Abstract
Most clinical miscarriages often occur throughout the first trimester of pregnancy, with fetal chromosomal abnormalities being identified as the primary reason for such occurrences. The objective is to analyze the fetal chromosomal aberrations in the product of conception among Iraqi patients suffering from recurrent miscarriages. The cross-sectional study was performed on 60 cases of products of conception in women suffering from multiple miscarriages, obtained from Department of Obstetrics and Gynecology is located in Ramadi Teaching Hospital for Child and Maternity, as well as other Private Clinics in the Ramadi City. Long-term culture of conventional cytogenetic analysis using the G-banding technique was employed to determine the chromosomal disorder of fetal tissue part or villus samples. Fetal chromosomal abnormalities were detected in 86.7 %. Numerical chromosomal abnormalities were revealed in 98.1 %, while structural abnormalities were detected in 1.9 %. Additionally, the commonest gestation loss occurs in parents under 35 years in the first trimester (92.3 %). Trisomy 21 was the most frequent (46.2 %) in gestational loss. Fetal chromosomal abnormalities have been linked with gestational loss in Iraqi couples. Therefore, it is recommended that cytogenetic analysis should be performed to identify the genetic cause of recurrent miscarriage. This is important for providing appropriate genetic counseling and educating couples about the risk of future pregnancies.

Abstract
The prognostic evaluation of myelodysplastic syndromes has evolved considerably over time, both due to the evolution of diagnostic classifications and the improvement in the prediction of the outcome. Many prognostic scores that have been developed over time take into account number and depth of blood cytopenias, as well bone marrow blast, cytogenetic, and more recently, molecular mutations. All these variables have been grouped together in IPSS-M score since 2022, which should quickly become a reference for the prognostic evaluation of MDS, as soon as molecular information is available for the patient.

Abstract
Myeloproliferative neoplasms, mastocytosis, myeloid/lymphoid neoplasms with hypereosinophilia and tyrosine kinase gene fusions, and myelodysplastic/myeloproliferative neoplasms are clonal hematopoietic cancers that, with the exception of certain entities, have an indolent course. In addition to their increasingly important role in the diagnosis of these entities, as shown by the recent classification of hematolymphoid tumors in the 5th edition of the World Health Organization and the International Consensus Classification of myeloid neoplasms and acute leukemias, identification of the profile of acquired genetic abnormalities is essential for adapting patient management and early detection of patients at high risk of progression. Alongside molecular abnormalities, cytogenetic abnormalities play an important role in the diagnosis, prognosis and follow-up of these diseases. Here, we review the recent literature on the impact of chromosomal abnormalities in these different entities and provide updated cytogenetic recommendations and guidelines for their management.

Abstract
Green biosynthesized nanoparticles have a bright future because they can be produced using a method that is more energy-efficient, cost-effective, repeatable, and environmentally friendly than physical or chemical synthesis. In this study, silver nanoparticles (AgNPs) were produced using the Fusarium nygamai isolate AJTYC1. Several techniques were used to characterize the synthesized AgNPs, including UV-Vis spectroscopy, transmission electron microscope, zeta potential analysis, X-ray diffraction analysis, energy dispersive X-ray, and Fourier transform-infrared spectroscopy. AgNPs showed a distinctive surface plasmon resonance (SPR) peak in the UV-visible range at 310 nm. The morphology of the biosynthesized AgNPs was spherical, and the TEM image shows that they ranged in size from 27.3 to 53.1 nm. The notable peaks of the FT-IR results show the different groups for the alkane, alkynes, cyclic alkenes, carboxylic, aromatic amine, esters, and phenolics. Additionally, the results showed that AgNPs had superior antioxidant activity when compared to ascorbic acid and butylated hydroxytoluene, which is a powerful antioxidant. Additionally, AgNPs have antibacterial action utilizing agar diffusion against gram-positive bacteria, gram-negative bacteria, and antifungal activity. AgNPs' anticancer activity varied depending on the type of cancer it was used to treat, including hepatocellular cancer (HepG2), colorectal carcinoma (HCT116), and breast cancer of the mammary gland (MCF7). The viability of the cancer cell lines was reduced with increasing AgNP concentration. AgNPs also demonstrated promising photocatalytic activity by reducing methylene blue, safranin, crystal violet, and green malachite by 88.3%, 81.5%, 76.4%, and 78.2%, respectively. In addition, AgNPs significantly affected the Allium cepa plant's mitotic index and resulted in chromosomal abnormalities as compared to the control. Thus, the synthesized AgNPs demonstrated an efficient, eco-friendly, and sustainable method for decolorizing dyes as well as antioxidant, antibacterial, antifungal, and anticancer activities. This could be a huge victory in the fight against numerous dynamic diseases and lessen wastewater dye contamination.

Abstract
INTRODUCTION Bladder cancer (BCa) is the most frequent cancer of the urinary tract, with more than 500,000 reported cases and nearly 200,000 related deaths yearly. Cystoscopy is the standard examination used for the initial diagnosis and follow-up of BCa in the noninvasive stage. However, the American Cancer Society does not include BCa screening in its list of recommended cancer screenings. AREAS COVERED Recently, several urine-based bladder tumor markers (UBBTMs) that identify genomic, transcriptomic, epigenetic, or protein alterations have been introduced, some of which have been approved by the Food and Drug Administration (FDA) to improve its diagnosis and surveillance. Several biomarkers have been found in the tissues and blood of individuals with BCa or predisposed to develop the disease, further enriching our information. EXPERT OPINION From a prevention perspective, alkaline Comet-FISH could be a valuable tool with broad potential for clinical application. Furthermore, a comet assay could be more beneficial for diagnosing and monitoring bladder cancer and determining individual susceptibility. Thus, we recommend further studies to understand the potential of this combined assay in the general population as a potential screening test and in patients initiated into the diagnostic process.

Abstract
OBJECTIVE To compare cytogenetic abnormalities among people living with HIV (PLWH) with and without previous exposure to Mycobacterium tuberculosis (Mtb) (both latent tuberculosis infection [LTBI] and active tuberculosis [TB]). METHODS Adult PLWH (≥18 years) were randomly selected at three HIV clinics in Uganda. Previous active TB was confirmed in the clinics' TB records. LTBI was defined as a positive QuantiFERON-TB Gold Plus assay. Participants' buccal mucosal exfoliated cells were examined (per 2000 cells) using the buccal micronucleus assay for chromosomal aberrations (micronuclei and/or nuclear buds), cytokinetic defects (binucleated cells), proliferative potential (normal differentiated cells and basal cell frequency) and/or cell death (condensed chromatin, karyorrhexis, pyknotic and karyolytic cells). RESULTS Among 97 PLWH, 42 (43.3%) had exposure to Mtb;16 had previous successfully treated active TB and 26 had LTBI. PLWH with exposure to Mtb had a higher median number of normal differentiated cells (1806.5 [1757.0 - 1842.0] vs. 1784.0 [1732.0 - 1843.0], p = 0.031) and fewer karyorrhectic cells (12.0 [9.0 - 29.0] vs. 18.0 [11.0 - 30.0], p = 0.048) than those without. PLWH with LTBI had fewer karyorrhectic cells than those without (11.5 [8.0 - 29.0] vs. 18.0 [11 - 30], p = 0.006). CONCLUSION We hypothesized that previous exposure to Mtb is associated with cytogenetic damage among PLWH. We found that exposure to Mtb is associated with more normal differentiated cells and less frequent karyorrhexis (a feature of apoptosis). It is unclear whether this increases the propensity for tumorigenesis.

Abstract
INTRODUCTION Fanconi anemia (FA) is a rare autosomal recessive disease characterized by chromosomal instability and increased predisposition to malignancy. The diagnosis of FA requires clinical evaluation, confirmation of chromosomal fragility and/or analysis of genetic mutations. Therefore, this study aims to identify the clinical profile of patients with FA in the state of Pernambuco, Brazil. METHOD We analyzed 100 individuals referred from the major hematology and bone marrow (BM) transplant centers in the state of Pernambuco, Brazil, between the years 2018 and 2022. The diagnosis of FA was performed using the mitomycin C chromosomal fragility test, clinical data and classical and molecular cytogenetic analyses. RESULTS We enrolled a total of 16 patients with FA to comprise this study. Most of these individuals (87.5%) came from the Agreste and Sertão regions of Pernambuco. We observed a slight female prevalence of FA (1.3:1). The primary clinical and laboratory findings were café au lait spots (62.5%) and bone abnormalities (53%, mainly thumb deformities [40%]). We performed BM cytogenetic analysis for eight patients - seven showed no chromosomal abnormalities and one presented the karyotype 47,XY,+21 [15]. CONCLUSIONS Our results are important to promote public health measures for the early diagnosis of FA, as well as to foster the engagement of a multidisciplinary group in the treatment of this disease.

Abstract
Plasma cell myeloma (PCM) is defined as a clonal disease of terminally differentiated plasma cells that secrete immunoglobulin. The biologic underpinnings of IgA-type multiple myeloma's (IgAMM) aggressive nature, including its increased morbidity and mortality, have not been elucidated. We describe the clinical, phenotypic, and cytogenetic characteristics of IgA-MM. Flow-cytometry analysis was performed to phenotype clonal plasma cell populations, and interface with fluorescent in situ hybridization (iFISH) to exploit cytogenetics to determine risk stratification; 68.1% of cases were of intermediate or high risk. On flow cytometry, samples from our IgA-PCM cohort revealed less frequent CD56 expression when compared to samples with other PCM subtypes. Our study demonstrated lower frequency of CD56 expression (52.8%). We hypothesize that loss of CD56 may play a significant role in the aggressive behavior of IgA-PCM due to the loss of cell-to-cell adhesion resulting in a higher propensity for extramedullary presentation.

Abstract
The dose-related effects of citrinin (CTN) on various physiological, cytogenetic, biochemical, and anatomical parameters using Allium cepa L. bulbs as a test material were researched in the present study. The physiological parameters examinated were fresh weight, root length, root number, and germination percentage; the cytogenetic parameters were micronucleus (MN) frequency, chromosome aberration (CA), and mitotic index (MI); the biochemical parameters were catalase (CAT), superoxide dismutase (SOD) activities, malondialdehyde (MDA) level, and free proline contents. And the anatomical changes in root tip cells were investigated by cross-sections. For this aim, onion bulbs were splitted four groups as three applications and one control. The bulbs in the control group were treated with distilled water; the bulbs in the application groups were treated with 1 μM, 5 μM, and 10 μM doses of CTN for 7 days. CTN application caused a decrease in the physiological parameters compared to the control group. This treatment created an increase in the frequency of MN and CA, and a reduce in the MI. In addition, it induced a dose-dependent increase in CAT and SOD activities and MDA and proline contents compared to the control group. Moreover, after CTN application, anatomical changes such as flattened nucleus, cell wall thickening, and cell deformation were identified and it was found that these changes reached their maximum at 10 mg/L dose CTN. Concequently, CTN caused inhibitory effects and the Allium test material was found to be a useful bioindicator for monitoring these effects.

Abstract
Background The karyotype is the important factor for the diagnosis and prognosis of primary myelodysplastic syndromes (MDS). Some previous studies have suggested that the incidence of chromosomal variations in MDS was related to race. We analyze the chromosomal characteristics in Vietnamese patients with MDS to find differences compared to other races and the association with subtypes by WHO classification. Methods Sixty patients with new primary MDS diagnoses underwent cytogenetic analysis and FISH for del(5q). Results Twenty-five patients (41.67%) had an abnormal karyotype at the time of diagnosis, in which 18 patients with a complex karyotype (≥3 chromosomal abnormality) represented the highest percentage (30%). The most frequent chromosomal abnormalities were +8 found in 10/60 patients (16.7%), del (5q) in 9/60 patients (15%), -18 in 5/60 patients (8.3%), only one patient had isolated del(5q) with 1.67%. Patients with abnormal karyotype had higher odds of being MDS-EB (MDS with excess blast) compared to those with normal karyotype (OR = 3.407, 95% CI = 1.164 - 9.976). Patients with complex karyotypes had a higher probability of having MDS-EB compared to those without complex karyotype (OR = 3.25, 95% CI = 1.018 - 10.379). Conclusions The complex karyotype was the most frequent chromosomal abnormality. Patients with an abnormal or complex karyotype had a higher probability of having MDS with excess blast. The isolated del (5q) ratio is very low compared to Europe and North Africa, but similar to China and Japan as they are the same countries in East Asia.

Abstract
Lippia alba is a phenotypically variable tropical shrub thought to comprise a young autopolyploid complex. Chromosome numbers in L. alba include 2n = 30, 38, 45, 60, and 90. High levels of chemical and phenotypic variation associated with economic and medicinal importance were reported. However, the genetic background including chromosome composition remains under-explored. Furthermore, the occurrence of at least four ploidal levels in L. alba and the lack of data for polyploid plants in tropical areas also merit further study of L. alba. Here we assessed the chromosome composition using two new satellite repeats (CL98 and CL66) applied as FISH probes to mitotic chromosomes, and we proposed to calculate the degree of homozygosis for CL66 satDNA (named as index h) and to associate it to meiotic instability. The CL98 mapping showed few variations in both number of signals and position. However, the levels of structural homozygosity for a satellite repeat CL66 were very variable. The numbers of CL66-bearing-chromosomes were under-represented in tetraploids relative to diploids implying that CL66 arrays have been lost in tetraploid lineages as a result of increased meiotic instability. High percentage of irregularities was observed in meiotic cells, especially in polyploids. L. alba complex comprised a mixture of homomorphic and heteromorphic chromosomes. Overall, the polyploid complex presents features typical of both young and older stable polyploids. It seems that L. alba genome is still in the process of stabilization.

Abstract
BACKGROUND Autologous stem cell transplantation (ASCT) after induction treatment is the standard of care. Our understanding of myeloma genetics has been very limited and its effect to stem cell mobilization is not widely investigated. We aimed to investigate the effect of genetic abnormalities on stem cell mobilization in myeloma. METHODS The data of 150 MM patients who underwent stem cell mobilization at our center between 2009-2020 were included and analyzed retrospectively. Pre-treatment bone marrow cytogenetics and fluorescence in situ hybridization tests were performed for each patient. RESULTS Groups were divided into two as patients with normal cytogenetic and abnormal cytogenetic. No difference observed between groups regarding age, gender and ECOG (p = 0.4; p = 0.2; p = 0.3). Groups were similar concerning myeloma characteristics, received treatment and treatment response. Median CD34+ cells/kg harvested was 444(2-11.29) in normal cytogenetic group whereas it was 4,8(2.4-8.6) in abnormal cytogenetic group(p = 0.2). Optimal CD34+ cells level achievement was 73 (67 %) in normal cytogenetic group while it was 25(71.4 %) in abnormal cytogenetic group(p = 0.6). Neutrophil and platelet engraftment durations were similar among cytogenetic groups (p = 0.7; p = 0.9). R-ISS based groups were also did not differ regarding harvested CD34+ cells and achievement optimal CD34 level (p = 0.79, p = 0.74). Engraftment durations for neutrophil and platelet were comparable between R-ISS based groups (p = 0.59, p = 0.65) CONCLUSIONS: Here we were not able to find any impact of genetic abnormalities on stem cell mobilization in myeloma patients. Expanded studies can aid to identify the effect of particular genetic anomalies on the stem cell mobilization.

Abstract
OBJECTIVE Ring chromosome 15 [r (15)], accompanied by a series of clinical symptoms, is a rare genetic disease. The genotype and phenotypic diversity of patients with r (15) still needed further enrichment. In this study we present a rare case of mosaic ring chromosome 15 with facial anomalies and extremities slenderness. CASE REPORT This case involves a 30-year-old woman, unpregnancy within 6 years. Clinical examination of the patient only revealed facial anomalies and extremities slenderness. The result of routine G-band karyotyping was 46,XX,r(15)(p12q26.3)[53]/46,XX,r(15;15)(p11.2q26.3;p11.2q11.2)[28]/45,XX, -15[10]/46,XX,r(15;15)(p11q26.3;p11q26.3)[4]. SNP array was employed to investigate the genome copy number variations (CNVs). The result revealed that there was a micro-duplication of 2.0 Mb at 15q26.3(arr[ph19]15q26.3 (100,400,214- 102,429,112)×3). The duplicated chromosomal section encompassed genes including CHSY1, ALDHIA3, LRRK1, and INS1. We further compared to the cytogenetic characteristics and clinical symptoms of the patient with those already reported by reviewing the literature. CONCLUSION This report is especially helpful to supplement the phenotypic diversity of patients with r (15).

Abstract
Background Myelodysplastic syndrome (MDS), a heterogeneous group of hematopoietic malignancy, has been shown to present different cytogenetic abnormalities, risk factors, and clinico-hematological features in different populations and geographic areas. Herein, we determined the cytogenetic spectrum and clinico-hematological features of Iranian MDS patients for the first time.
Methods This prospective cross-sectional study was conducted on 103 patients with MDS in Ahvaz, southwest of Iran, from 2014 to 2018. Clinical presentations, complete blood counts (CBC), and bone marrow (BM) biopsy samples were assessed. Perls' staining was used to evaluate BM iron storage. The cytogenetic evaluation was performed using the conventional G banding method on the BM. Results Patients’ median age was 62.3 (ranged from 50–76), and the majority were male (72.8%). The most common clinical symptom at the time of admission was fatigue (n = 33) followed by pallor (n = 27). The most common subgroup was MDS-Multi Lineage Dysplasia (MDS-MLD) (n = 38, 36.8%), followed by MDS-Single Lineage Dysplasia (MDS-SLD) (n = 28, 18.4%). A normal karyotype was observed in 59 patients (57.3%), while 44 patients (42.7%) had cytogenetic abnormalities. Trisomy 8 (+ 8) was the most common cytogenetic abnormality (n = 14) followed by del 17p (n = 9) and monosomy 7 (− 7) (n = 7). Twelve patients (11.65%) were transformed to AML. Conclusion Our data betokened that among our MDS patients, Trisomy 8 is the predominant cytogenetic abnormality, and MDS-MLD and MDS-SLD are the most common of subtypes. Noteworthy, the male: female ratio was slightly higher in Iran than in previous reports from other parts of the world. Our study is the first report of the clinical, hematological, and cytogenetic spectrum of MDS patients in Iran

Abstract
Autism spectrum disorders are neurodevelopmental complex diseases with causative de-novo and inherited genetic factors. They include a range of cognitive and behavioral conditions such as pervasive developmental disorder, Asperger's syndrome, and autism. Cytokinesis-block micronucleus assay, as a cytogenetic study has been considered as one of the indicators of chromosomal damage in peripheral blood. This study aimed to investigate the frequency of micronucleus (MN) in peripheral blood lymphocytes of parents with autistic children. The study was case-control and the cases were parents of autistic children referring to the psychiatric department of the Ali-Asghar Hospital of Tehran. The total number of samples was 60 cases and 30 controls. The results showed that autistic children's parents had a significant increase in MN frequency in binucleated lymphocytes. Further researches are suggested to analyze the environmental and genetic reasons for MN increase in autistic children parents.

Abstract
Isodicentric Y chromosome [idic(Y)] is one of the most common structural abnormalities of the Y chromosome and has been observed in patients with reproductive disorders and in patients with disorders of sexual development. Most idic(Y) chromosomes are found in mosaic form with a 45,X cell line. These chromosomes are highly unstable during mitosis due to the presence of 2 centromers, which explains their probable loss in early mitosis or mitosis of the embryo and therefore the presence of the 45,X line. It has been hypothesized that the proportion of 45,X cells in various tissues probably influences the phenotypic sex of individuals carrying an idic(Y) chromosome, ranging from infertile men, hypospadias, ambiguous genitalia, and Turner syndrome to sex reversal. In this article we present 5 cases of patients with idic(Y) referred for suspected disorder of sex development (DSD), 3 with a male assignment and 2 with a female assignment. All cases have variable clinical characteristics, which were assessed by the transdisciplinary group of Disorders of Sex Development of the Hospital Universitario San Ignacio, Bogotá, Colombia. Patients were analyzed by conventional and molecular cytogenetics using high-resolution G-band and FISH techniques. Our findings highlight the importance of cytogenetic studies in the diagnosis of DSD patients.

Abstract
The prognosis of patients with hypoplastic myelodysplastic syndrome (hMDS) after receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains unclear. This study aimed to evaluate the outcomes of patients with hMDS after allo-HSCT. Between September 2013 and October 2019, a total of 20 consecutive patients with hMDS and 1 patient with clonal cytopenia of undermined significance (CCUS) who underwent allo-HSCT, which included procedures with 9 matched sibling donors, 2 matched unrelated donors, 4 mismatched unrelated donors and 6 haploidentical donors, were enrolled in this study. The median time for myeloid engraftment was 11 days (range 9-17 days), and that for platelet engraftment was 10 days (range 7-17 days). The cumulative incidence (CI) of myeloid and platelet recovery was 95.2 ± 6.0% and 90.5 ± 7.3%, respectively. The CI rates were 40.0 ± 11.3% for grades II-III acute graft-versus-host disease (GVHD), 36.8 ± 11.5% for chronic GVHD and 23.8 ± 9.6% for nonrelapse mortality. No patients experienced relapse. Sixteen surviving patients were followed up for a median of 1113 days (range 110-2305 days), and the overall survival and relapse-free survival rates were both 72.7 ± 10.6%. This limited retrospective analysis suggests that patients with hMDS had a favorable survival after allo-HSCT.

Abstract
Citrinin (CIT) is a cytotoxic, hepatotoxic, nephrotoxic and cardiotoxic metabolite obtained from Penicillium citrinum, that has been increasingly searched as an anticancer drug candidate. In this study, we assessed the antitumor effects of citrinin, using cytogenetic biomarkers for genotoxicity in Sarcoma 180 (S-180) ascitic fluid cells of mice. Citrinin, extracted from P. citrinum acetonitrile extract, was characterized by LC-MS. Cytotoxic assessment was done through using comet (alkaline version) and micronucleus assays. In S-180 cells, CI50 of CIT was 3.77 μg/mL, while at 12.5 and 100 μg/mL, CIT was as cytotoxic as doxorubicin (2 μg/mL). At 0.5, 1.0 and 2.0 μg/mL, it induced genotoxicity and mutagenicity in S-180 cells, especially at 2 μg/mL, triggering oxidative damage similar to hydrogen peroxide (10 mM). The antitumor effects were evidenced by a marked increase in S-180 cells apoptosis and necrosis due to clastogenic and/or aneugenic cytogenetic effects (micronucleus formation), as well as by induction of nucleoplasm bridges and nuclear buds, culminating in S-180 apoptosis and necrosis. CIT has potential as drug candidate for antitumor purposesbyinvolving cytogenetic mechanisms.

Abstract
Biomarkers are indicators of pathogenic processes, typical biological processes, or pharmacological reactions to a therapy. It has several potential usages in cancer; differential diagnosis, prognosis, risk assessment, therapeutic response, and monitoring of disease progression. Recently, advances in oncomarkers raised significant opportunities for enhancing management of cancer. Chromosomal aberration, molecular impairment and epigenetic alteration might be applied to diagnose and prognose cancer and its epidemiology. Some oncomarkers are specific and highly sensitive for detection. An oncomarker might be used to see how the body reacts to an intervention or a situation. The present study represents a short review about various genetic oncomarkers with diagnostic and prognostic values.

Abstract
Background Uveal melanoma is the commonest intraocular malignant tumor in adults and the choroid is the commonest involved location. It is more prevalent in Caucasians; however, the demographics are widely variable based on ethnicity. Histopathological features have been correlated to the cytogenetic profile, which we intend to report through the study of enucleated eyes with choroidal melanoma (CM). Materials and Methods A retrospective review of 28 enucleated globes with CM in 2 tertiary eye centers (January 2000-December 2017). The tumors were histopathologically classified based on the 8th edition of the American Joint Committee on Cancer (AJCC). The histopathological risk factors and the AJCC classifications were correlated with Fluorescence in situ hybridization (FISH) for chromosomes 3 and 8 available results in 18/28 eyes. Results We have included 28 patients with a mean age of 56 years, 13 males (46.4%) and 15 females (53.6%). None had lymph node involvement or metastatic disease. The tumor size was categorized as 3 and 4 in 68% of eyes. Half tumors were of spindle cell type and were associated with absent cytogenetic abnormality in chromosomes 3 and 8 (P=0.005). Closed vascular loops presence was significantly associated with abnormal chromosomes 3 and 8 (P=0.027). Conclusion Patients in our area presented late with larger tumor size. The spindle cell CM was the commonest and correlated with negative FISH results, while the presence of closed vascular loops was a risk factor for abnormal FISH results hence expected worse prognosis. AJCC classification did not correlate well with our FISH results.

Abstract
To function, mobile phone systems require transmitters that emit and receive radiofrequency signals over an extended geographical area exposing humans in all stages of development ranging from in-utero, early childhood, adolescents and adults. This study evaluates the question of the impact of radiofrequency radiation on living organisms in vitro studies. In this study, we abstract data from 300 peer-reviewed scientific publications (1990-2015) describing 1127 experimental observations in cell-based in vitro models. Our first analysis of these data found that out of 746 human cell experiments, 45.3% indicated cell changes, whereas 54.7% indicated no changes (p = 0.001). Realizing that there are profound distinctions between cell types in terms of age, rate of proliferation and apoptosis, and other characteristics and that RF signals can be characterized in terms of polarity, information content, frequency, Specific Absorption Rate (SAR) and power, we further refined our analysis to determine if there were some distinct properties of negative and positive findings associated with these specific characteristics. We further analyzed the data taking into account the cumulative effect (SAR × exposure time) to acquire the cumulative energy absorption of experiments due to radiofrequency exposure, which we believe, has not been fully considered previously. When the frequency of signals, length and type of exposure, and maturity, rate of growth (doubling time), apoptosis and other properties of individual cell types are considered, our results identify a number of potential non-thermal effects of radiofrequency fields that are restricted to a subset of specific faster-growing less differentiated cell types such as human spermatozoa (based on 19 reported experiments, p-value = 0.002) and human epithelial cells (based on 89 reported experiments, p-value < 0.0001). In contrast, for mature, differentiated adult cells of Glia (p = 0.001) and Glioblastoma (p < 0.0001) and adult human blood lymphocytes (p < 0.0001) there are no statistically significant differences for these more slowly reproducing cell lines. Thus, we show that RF induces significant changes in human cells (45.3%), and in faster-growing rat/mouse cell dataset (47.3%). In parallel with this finding, further analysis of faster-growing cells from other species (chicken, rabbit, pig, frog, snail) indicates that most undergo significant changes (74.4%) when exposed to RF. This study confirms observations from the REFLEX project, Belyaev and others that cellular response varies with signal properties. We concur that differentiation of cell type thus constitutes a critical piece of information and should be useful as a reference for many researchers planning additional studies. Sponsorship bias is also a factor that we did not take into account in this analysis.

Abstract
To investigate the role of CD27 in multiple myeloma(MM), bone marrow samples from 165 newly diagnosed MM were analysed by flow cytometry. CD27- group (n = 93) had higher level of plasma cell proportion (37.00% vs 22.50%, p < .05), β2-MG (5.42 vs 3.20 mg/L, p < .05), calcium (2.45 vs 2.28 mmol/L, p < .05),higher percentage of ISS stage III (49.46% vs 22.22%, p < .05) and patients with ≥2 high-risk cytogenetics (24.73% vs 15.28%, p < .05) than CD27+ group (n = 72). After 4 cycles of chemotherapy, the overall response rate in CD27- group were lower than CD27+ group (56.67% vs 73.02%,p < .05). After a median follow-up of 18 months, progression-free survival was significantly shorter in CD27- group than in CD27+ group (22 vs 40 months, p < .05), so was overall survival (median OS not reached, p < .05). Gene sequencing showed more adverse mutations in CD27- group than CD27+ group.

Abstract
In this study, the toxic effects of epiclorohidrine (ECh) were investigated in vivo by Allium test. The toxic effects have been investigated in terms of physiological, cytogenetic, anatomical, and biochemical aspects. The changes in germination percentage, weight gain, and root length were investigated as physiological parameter; micronucleus (MN), mitotic index (MI), and chromosomal abnormality (CA) frequencies were as cytogenetic parameter. Oxidative stress indicators such as superoxide dismutase (SOD), catalase (CAT), and malondialdehyde (MDA) were analyzed for biochemical changes and also damages in root tip cells were evaluated as anatomical parameter. It was determined that germination percentage, weight gain, root length, and MI decreased; MN and CA frequencies were increased with the increase of ECh treatment dose. ECh treatment caused significant increase in SOD and CAT enzyme activities and MDA levels and these results indicated a stress formation. A variety of anatomical changes and damages were observed in the root tip cells induced by ECh. In conclusion, the toxic effects of ECh on A. cepa which is a model of eucaryotic cell were investigated in a multi-directional way and serious toxic effects of ECh treatment were determined.

Abstract
OBJECTIVE This study aimed to evaluate the genotoxic effects in the oral epithelial cells of patients undergoing fixed orthodontic treatment and to compare these to a control group without treatment. The null hypothesis to be tested is that corrective orthodontic treatment at different periods does not cause genotoxic effects in patients. MATERIAL AND METHODS An observational cross-sectional study including 74 patients enrolled in corrective orthodontic treatment and 21 control patients, between 11 and 35 years of age, of both genders, participated in the research. Patients undergoing treatment were divided into four treatment groups differentiated by treatment periods: G1, n = 21 (1 month to 12 months); G2, n = 21 (13 to 24 months); G3, n = 23 (25 to 48 months); and G4, n = 9 (over 48 months). Cells were collected by scraping the internal side of the cheek and subsequently placed in tubes containing 0.9% sodium chloride solution. The sample underwent evaluation for genotoxic effects by means of the micronucleus test (MNT). Bivariate analyses were performed using parametric tests (t test or ANOVA) and nonparametric tests (Chi-square test, Kruskal-Wallis test, Dunn post-test). The adopted level of significance was 5%. RESULTS Statistically significant differences for any of the genotoxic abnormalities (binucleated, trinucleated, karyolysis, piknosis, nuclear buds) were not found except for karyolysis, which was higher in the control group than in G4 (p < 0.05). CONCLUSIONS This study did not demonstrate evidence of genotoxic effects even after long periods of corrective orthodontic treatment. CLINICAL RELEVANCE This study explores genotoxic effects in fixed orthodontic patients.

Abstract
INTRODUCTION Chimerism is defined as coexistence of different cell lines in an individual. 46,XX/46,XY chimerism is very rare and exhibits broad range of clinical phenotypes. Most cases are detected at infancy or younger age due to disorders of sex development, while phenotypically normal cases are incidentally discovered through abnormal blood grouping results or multiple genotypes in HLA. OBJECTIVE Aim was to determine the genetic expression of numerous HLA alleles detected in phenotypically normal 46,XX/46,XY chimerism. MATERIALS AND METHODS A patient was admitted for lung transplantation due to end-stage pulmonary disease. Pre-transplantation work-up included blood group typing and HLA DNA typing analyses. Peripheral blood and hair follicle specimens were used to confirm unusual tri-allelic results by high-resolution PCR-SBT. Cytogenetic analyses of karyotyping, FISH and chromosomal microarray were done. Flowcytometry crossmatch analysis was conducted using lymphocytes and anti-HLA sera defined by Luminex panel reactive antibody test (One Lambda, Inc., Canoga Park, CA), to determine antigen expression of HLA alleles. RESULTS 46,XX/46,XY chimerism was confirmed through series of cytogenetic analyses. HLA typing of the patient revealed three alleles from HLA-A, -B and -DRB1 loci. Antigen expression of all 3 HLA alleles was confirmed by flow cytometry crossmatch. DISCUSSION A case of normal phenotype 46,XX/46,XY chimerism was detected for the first time in Korean patient admitted for lung transplantation. Cytogenetic results were confirmatory for chimerism and HLA typing using PCR-SBT method was able to detect the presence of 3 HLA alleles. Flowcytometry crossmatch was proven sensitive for detecting antigen expression of different cell lines of small proportions.

Abstract
The domestic water buffalo (Bubalus bubalis) is an economically important livestock species in many Asian and Mediterranean countries. Two types of water buffalos are river and swamp buffaloes. Genetically, the swamp buffalo has 48 chromosomes (2n = 48) and the river buffalo has 50 chromosomes (2n = 50). Khuzestan province is one of the important centers of buffalo farming in Iran. Since there was no cytogenetic information about Khuzestani buffalo breed, the present study was performed to provide karyotype and cytogenetic study in Khuzestan buffaloes. In this study, blood samples of 40 buffaloes were collected randomly from jugular vein via heparinized syringes. For metaphase smear, blood samples were cultured in RPMI 1640 medium containing fetal bovine serum and phitohemaglutination and then transferred to water bath for 69 hr. After stopping cell division by colcemide and using fixed solution, from each sample six slides were stained with Giemsa staining. Based on the results, number of chromosomes of the Khuzestani buffaloes was 50 (2n = 50). Among the 25 pairs of chromosomes, the first 5 pairs of autosomal chromosomes were sub-metacentric, 19 pairs of autosomal ones were acrocentric and the sex chromosomes (X and Y) were acrocentric. Furthermore, X and Y chromosomes were the largest and smallest acrocentric ones, respectively. Therefore, the buffaloes of Khuzestan province are considered as a river type. .

Abstract
In this article several members of diverse scientific associations and reproduction experts from Spain have updated different genetic and immunological procedure recommendations in couples affected by reproductive dysfunction with the goal of providing a set of useful guidelines for the clinic. The laboratory test has been considered as highly recommendable for making clinical decisions when the result of the diagnostic test is relevant, moderately recommendable when the results are of limited evidence because they are inconsistent, and low when the benefit of the test is uncertain. It is expected that these recommendations will provide some useful guidelines for the diagnosis, prognosis and treatment of couples presenting reproductive dysfunction.

Abstract
Objective: To evaluate the difference between chromosomal abnormalities between the gender of couples affected by Recurrent miscarriage (RM) and if there is an association between previous obstetric history and chromosomal abnormalities of the parents.Methods: Multicenter, retrospective, observational study from seven different RM clinics between 2006 and 2016. We enrolled 707 couples (1014 participants) with a history of RM. We compared the frequency of chromosomal abnormalities between groups of couples with primary and secondary RM and separated between women and their partners. Furthermore, we compared the prevalence of chromosomal abnormalities between groups based on the number of previous spontaneous abortions.Results: The overall prevalence of all cytogenetic abnormalities was 5.59% (n = 1414, women and their partners). Excluding cases of polymorphism and inversion of chromosome 9, which are considered variants of normality, the prevalence in all individuals was 2.26% (n = 32/1414). The comparative analysis of cases of chromosomal abnormalities among couples with primary and secondary RM based on the number of previous miscarriages (PM) revealed a similar frequency between groups. The statistical analysis of the total cases (primary PM + secondary PM) in these three groups were as follows: (a) couple, 2 pm versus 3 pm vs. ≥4 PM, p = .514; (b) women, 2 pm versus 3 pm vs. ≥4 PM, p = .347; and (3) partner, 2 pm versus 3 pm vs. ≥4 PM, p = .959. Chromosomal abnormalities were significantly more prevalent among women than among their partners (6.9 versus 4.2%; p = .027). Moreover, the distribution of leading chromosomal abnormalities among women was different compared with their partners. Among women, we observed these abnormalities in the following frequency order: mosaicism (38.8%), polymorphism (32.6%), translocation (16.3%), and inversion (12.3%). Among their partners, these abnormalities were polymorphism (73.3%), inversion (13.3%), mosaicism (6.7%), and translocation (6.7%).Conclusion: The number of PM and the history of full-term pregnancy does not correlate with an increase or decrease in the prevalence of cytogenetic abnormalities in couples with RM.

Abstract
Selenium nanoparticles has important role in repression of cytogenetic toxicity and DNA damage in hepatocellular carcinoma rat model. HCC rat model treated with doxorubicin drug had low frequencies in DNA damage, chromosomal aberrations and micronucleus formation than untreated animals. Treatment of HCC rat model with doxorubicin and Nano-Se together resulted in decreased cytogenetic toxicity. So the combination of doxorubicin with nanoselenium better than doxorubicin alone. More scientific studies are needed to support the use of Nano-Se for human disease prevention or lifespan extension.
The present study aimed to demonstrate the potent role of nanoselenium and Doxorubicin in retrogression of genotoxicity induced in hepatocellular carcinoma rat model by studying chromosomal aberration, micronuclei formation, DNA fragmentation as well as comet assay. Male rats hepatocellular carcinoma model were treated with Se-Nanoparticles, Doxurobicin (DOX) and the combination of both. The results revealed the protective effect of nanoselenium, Doxorubicin and their combination on bone marrow cytogenetic toxicity by decreasing chromosomal aberrations and micronuclei formation as well as their effects on rat's liver by decreasing DNA damage. Nevertheless, the treatment with nanoselenium either alone or in combination with Doxorubicin was more effective than treatment with doxorubicin alone.

Abstract
The presence of cytogenetic clonal heterogeneity has been associated with poor prognosis in patients with acute myeloid leukemia (AML). Here, we reassessed this association. The study cohort consisted of all patients with an abnormal karyotype randomized in the EORTC/GIMEMA AML-10 and AML-12 trials. Abnormal karyotypes were classified as no subclones present (cytogenetic abnormality in a single clone), defined subclones present (presence of one to three subclones), and composite karyotypes (CP) (clonal heterogeneity not allowing enumeration of individual subclones). The main endpoints were overall survival (OS) and disease-free survival (DFS). Among 1291 patients with an abnormal karyotype, 1026 had no subclones, 226 at least 1 subclone, and 39 a CP. Patients with defined subclones had an OS similar to those with no subclones (hazard ratio (HR) 1.05, 95% confidence interval (CI) 0.88-1.26), but CP patients had a shorter OS (HR = 1.58, 95% CI 1.11-2.26). However, in a multivariate Cox model stratified by protocol and adjusted for age, cytogenetic risk group, secondary versus primary AML, and performance status, clonal heterogeneity lost its prognostic importance (HR = 1.10, 95% CI 0.91-1.32 for defined subclones versus no subclones; HR = 0.96, 95% CI 0.67-1.38 for CP versus no subclones). Also, the impact of having a donor on DFS was similar in the three clonal subgroups. In summary, in patients with cytogenetic abnormality, presence of subclones had no impact on OS. The dismal outcome in patients with a CP was explained by the known predictors of poor prognosis.

Abstract
OBJECTIVES To evaluate the genotoxic and cytotoxic effects of Haas appliances through micronuclei test and cytogenetic damage analysis in buccal mucosa epithelial cells of patients undergoing orthodontic treatment. MATERIALS AND METHODS Twenty-eight patients, 6-12 years of age and of both genders, who required a Haas appliance for the correction of a posterior crossbite were included. Epithelial cells from the mucosa were collected by gently scraping the inside of both the right and left cheeks. The cells were collected before the insertion of the appliance (T0), 1 month after the device was installed (T1), and again 3 months after the appliance was immobilized (T2). The cells were processed to obtain slides. Feulgen/Fast Green was used as the staining method, and the number of normal, karyolytic, pyknotic, nuclear buds, bi/trinucleated, and micronucleus cells were counted under light microscopy. Cellular abnormalities were evaluated with parametric and nonparametric tests for comparison of the means by analysis of variance testing, Tukey posttest, or the Kruskal-Wallis test and then by Dunn's posttest. The significance level was 5%. RESULTS There were no statistically significant changes in the micronuclei in the evaluated periods ( P > .05). Nuclear buds increased at T1 ( P < .05), returning to baseline levels at T2. Other abnormalities (cariolytic, pyknotic, and bi/trinucleated cells) showed a significant increase at T1 and T2 ( P < .0001). CONCLUSIONS The Haas appliance did not cause an increase in micronuclei in cells of the buccal mucosa. However, statistically significant increases in cariolytic, pyknotic, and bi/trinucleated cells were observed during treatment, suggesting possible DNA damage.

Abstract
The male factor contributes to 50% of infertility. The cause of male infertility is idiopathic and could be congenital or acquired. Among different factors which are involved in idiopathic male infertility, genetic factors are the most prevalent causes of the disease. Considering, the high prevalence of male infertility in Iran and the importance of genetic factors in the accession of it, in this article we reviewed the various studies which have been published during the last 17 yr on the genetic basis of male infertility in Iran. To do this, the PubMed and Scientific information database (SID) were regarded for the most relevant papers published in the last 17 yr referring to the genetics of male factor infertility using the keywords ''genetics'', "cytogenetic", ''male infertility", and "Iranian population". Literatures showed that among the Iranian infertile men Yq microdeletion and chromosomal aberrations are two main factors that intervene in the genetics of male infertility. Also, protamine deficiency (especially P2) is shown to have an influence on fertilization rate and pregnancy outcomes. The highest rate of sperm DNA damages has been found among the asthenospermia patients. In several papers, the relation between other important factors such as single gene mutations and polymorphisms with male infertility has also been reported. Recognition of the genetic factors that influence the fertility of Iranian men will shed light on the creation of guidelines for the diagnosis, consultation, and treatment of the patients."

Abstract
Background The only potentially curative therapy for myelodysplastic syndrome is allogeneic hematopoietic cell transplant; unfortunately, there is a high relapse rate. The objective of this study was to perform a detailed clinicopathologic study of patients with relapsed myeloid neoplasm following allogeneic hematopoietic cell transplant for myelodysplastic syndrome. Methods Pre-transplant, post-transplant, and relapse bone marrow and peripheral blood morphologic features (including dysplasia) were retrospectively evaluated by study authors. Clinical features and results of cytogenetic analysis and engraftment/chimerism studies were obtained from the medical record. Results Our study describes 21 patients with a median time to relapse of 6 months (range 2-82). Ten of the patients relapsed with higher grade disease, including six with overt acute myeloid leukemia. Pre-transplant megakaryocyte dysplasia was associated with dysplastic megakaryocytes in the relapse specimen; however, neither erythroid dysplasia nor granulocytic dysplasia were associated with their counterpart in the relapse specimen. Relapse specimens had a lower marrow cellularity and higher blast percentage than pre-transplant disease. Cytogenetic comparisons before and after transplant showed variety, including clonal evolution (22%), the same abnormal clone (33%), or a different abnormal clone (22%). Conclusions Our detailed review of post-transplant marrow biopsies prior to relapse highlights the difficulty in diagnosing relapse and particularly impending relapse.

Abstract
PURPOSE To determine the factors associated with outcomes in patients with core binding factor acute myeloid leukemia (CBF-AML) in first relapse. MATERIAL AND METHODS We conducted a retrospective analysis of 92 patients with CBF-AML in first relapse who presented to our institution from 1990-2014. Clinical and demographic parameters were included in univariate and multivariate Cox proportional hazards regression model to predict overall survival. RESULTS Among the 92 relapsed patients, 60 (65%) patients had inv (16) and 32 (35%) had t (8;21). The median survival for patients with inv(16) cytogenetic group was 15.6 months (range 10.32 to 20.88 months) while for the t(8;21) group was 9 months (range 3.68 to 14.32) (P = .004). Univariate Cox model analysis showed that increased age, high white blood cell count, t (8;21) cytogenetic group, and high bone marrow blast percentage were associated with poor overall outcome, while stem cell transplant intervention was associated with better survival. Additional cytogenetic aberrations at relapse were not associated with survival outcomes (P = .4). Multivariate Cox model analysis showed that t(8;21) cytogenetic group has more hazard of death after adjusting, age, marrow blast percentage, blood cell count, and stem cell transplant(hazard ratio 1.802; P = .02). CONCLUSION Among patients with relapsed CBF-AML, median survival was less than a year and half and the outcome was worse in patients with t (8;21). Despite the relatively better outcomes, dedicated clinical trials are needed to improve the outcome in all patients with relapsed CBF-AML.

Abstract
Acute myeloid leukemia (AML) is a group of hematological diseases, phenotypic and genetically heterogeneous, characterized by abnormal accumulation of blast cells in the bone marrows and peripheral blood. Its incidence rate is approximately 1.5 per 100,000 in infants younger than 1 year of age and 25 per 100,000 persons in octogenarians. Traditionally, cytogenetic markers are used to stratify patients in three risk categories: favorable, intermediate and unfavorable. However, the forecast stratification and the treatment decision for patients with normal karyotype shows difficulties due to the high clinical heterogeneity. The identification of several genetic mutations additional to classical molecular markers has been useful in identifying new entities. Nowadays, many different mutations and epigenetic aberrations have been implicated in the diagnostic, prognostic and treatment of AML. This review is focused on describing the most important molecular markers with implications for clinical practice.

Abstract
BACKGROUND Meningiomas are the most common primary intracranial tumor, but the lack of prospective randomized trials has led to different guidelines for their treatment. We proposed a classification of meningiomas that considers surgical removal, histology, and cytogenetic profile, based on a literature review of these 3 criteria. The classification can be used to guide adjuvant treatment and follow-up. METHODS A retrospective literature review was performed of PubMed from 2007 to 2016. Search terms were "meningioma," "surgery," "WHO classification," "cytogenetic," and "algorithm." RESULTS Meningiomas were classified into 5 groups (A-E) according to the Simpson resection grade, World Health Organization grade, and cytogenetic profile. Adjuvant therapy, follow-up magnetic resonance imaging, and management of recurrence and/or regrowth were proposed according to the classification. CONCLUSIONS The proposed meningioma classification was based on our experience and retrospective evidence collated from the literature and supported by recommendations. The application of the classification criteria yielded an algorithm for treatment and follow-up of patients with meningioma.

Abstract
Pesticides are a complex mixture of chemicals used to protect crops from a number of pests and diseases. They have been considered as potential mutagenic agents. This study aims at evaluation of the mutagenic effect of pesticide exposure to agricultural workers through chromosomal aberrations (CA) and micronucleus (MN) assay in peripheral blood lymphocytes and oral mucosal cells, respectively. The exposed group was consisted with 97 farmers, while the control (un-exposed) group consisted of 55. The results showed a significant (p < 0.05) increase in frequency of CA and MN in the exposed group. Both CA and MN profiles were linked to a significant (p < 0.05) co-relation with the confounding factors such as smoking habits, alcohol, vegetables, tea/coffee, vitamins, and sweetener consumptions. More cytogenetic events were denoted in smoking and alcohol consumption as well as non-personal protective equipment (non-PPE) and low/no vegetables user farmers. In conclusion, a deficiency of dietary and medicaments-derived antioxidants, while consumption of alcohol and tobacco, as well as effects of radiation, heavy metal poisoning (especially from sweeteners), and non-PPE using habits, may contribute cytogenetic damage to the workers.

Abstract
BACKGROUND Brazilian gas station workers are chronically exposed to benzene, toluene, xylene (BTX) during their working time. Describe below two cases of latin female gas station workers with benzene poisoning symptoms and miscarriage history. CASE PRESENTATION In both cases were identified complex chromosomal rearrangements (CCR) with fluorescence in situ hybridization, applied to whole chromosome paints by chromosomes 1, 2 and 4. The lower natural killer cell (NK) cells have also been observed in cases correspondents, especially the rare type of NK (NKbright) in their peripheral blood cells. CONCLUSIONS It is known that acquired chromosomal aberrations are positively correlated with cancer and reproductive risk. In concordance, lower NK cytotoxicity increases the risk for cancer, as well. Thus, this is the first study providing hints on a possible causative relation of lower NK cytotoxicity and increase rates of chromosomal rearrangements including CCRs.

Abstract
The main databases devoted stricto sensu to cancer cytogenetics are the "Mitelman Database of Chromosome Aberrations and Gene Fusions in Cancer" ( http://cgap.nci.nih.gov/Chromosomes/Mitelman ), the "Atlas of Genetics and Cytogenetics in Oncology and Haematology" ( http://atlasgeneticsoncology.org ), and COSMIC ( http://cancer.sanger.ac.uk/cosmic ).However, being a complex multistep process, cancer cytogenetics are broadened to "cytogenomics," with complementary resources on: general databases (nucleic acid and protein sequences databases; cartography browsers: GenBank, RefSeq, UCSC, Ensembl, UniProtKB, and Entrez Gene), cancer genomic portals associated with recent international integrated programs, such as TCGA or ICGC, other fusion genes databases, array CGH databases, copy number variation databases, and mutation databases. Other resources such as the International System for Human Cytogenomic Nomenclature (ISCN), the International Classification of Diseases for Oncology (ICD-O), and the Human Gene Nomenclature Database (HGNC) allow a common language.Data within the scientific/medical community should be freely available. However, most of the institutional stakeholders are now gradually disengaging, and well-known databases are forced to beg or to disappear (which may happen!).

Abstract
Objective This study was carried out to investigate the ability of Propolis to ameliorate the adverse cytogenetic effects of Dacarbazine on bone marrow cells Methods In this experimental in vivo study, 18 mice were used, divided into four groups: control group; Propolis-treated group (treated with 50mg/kg Propolis); and Dacarbazine-treated group (treated with 3.5mg/kg Dacarbazine). The fourth, fifth, and sixth were treated with Dacarbazine and Propolis as pre 2h, post 2h, and concomitant treatment. After five days, the Bone Marrow (BM) samples were obtained for cytogenetic investigation. Results The in vivo studies revealed that Dacarbazine induced an abnormalities in polychromatic erythrocytes cells (PECs) as increase of cell with micronuclei, while the dual treatment accompanied with improvement of this abnormalities. Conclusions It could be concluded that there are protective effects of Propolis against the adverse effects of Dacarbazine. It could be recommended to use Propolis as an adjuvant with chemotherapeutic agents.

Abstract
MYC and BCL2 translocations in B-cell lymphomas are defined as "double-hit" associated with poor prognosis in adult patients. Such double-hit events are extremely rare in B-cell precursor acute lymphoblastic leukemia (BCP-ALL), especially in pediatric patients or young adults. This study is to investigate the clinical manifestation of de novo MYCyBCL2 double-hit BCP-ALL in young patients. Two pediatric and one young adult patients were identified after a retrospective data review and all without previous history of lymphoma. There were two females and one male aged 15, 18, and 24, respectively. All patients had an unremarkable medical history before presenting with extensive bone marrow and central nervous system involvement at diagnosis. Flow cytometry immunophenotypic analysis showed an immature B-cell immunophenotype (CD10+, CD19+, TdT+, surface Ig-) and immunohistochemistry showed high expression of MYC and BCL2 in all cases. All patients showed complex karyotypes associated with 8q24 abnormalities in the form of t(8;9)(q24;p13) or t(8;14)(q24;q32) and t(14;18)(q32;q21) and fluorescence in situ hybridization confirmed MYC and BCL2 rearrangements. Two patients died of refractory disease or disease progression 7 and 13 months after initial diagnosis, respectively, and the third patient was treated with protocol AALL0232 under the Children's Oncology Group study, achieved complete remission and remained in remission for 53 months at last follow-up. Our study showed that De novo MYCyBCL2 double-hit BCP-ALL is a rare disease that also occurs in pediatric and young adult patients and associated with complex karyotypes and poor prognosis. Younger patients may benefit from intensified chemotherapy.

Abstract
Leukemic non-nodal mantle cell lymphoma (lMCL) is a particular subtype of mantle cell lymphoma (MCL), characterized by leukemic non-nodal disease and slow progression. Recognition of this entity is relevant to avoid overtreatment. Despite indolent clinical behaviour, lMCL might transform to a more aggressive disease. The purpose of this study was to compare lMCL with classical MCL (cMCL) and aggressive MCL (aMCL) using immunohistochemistry, interphase fluorescence in situ hybridization (FISH), and array-based comparative genomic hybridization, in order to identify biomarkers for lMCL diagnosis and prognosis. Seven lMCL patients were included. All had bone marrow involvement without lymphadenopathy. An lMCL phenotype was distinct from that of cMCL and aMCL: SOX11-, ATM+, PARP1+/-, and low KI67 (average 2 %). Beyond the t(11;14) translocation, fewer secondary cytogenetic alterations were found in lMCL compared to cMCL and aMCL, including deletion of PARP1 and 13q14. At last follow-up, one patient with lMCL had died of disease and another had progressive disease. These patients were respectively 13q14 deletion- and PARP1-positive. One other case of lMCL harbored a 13q14 deletion associated with PARP1 deletion. This patient had indolent disease. lMCL has a particular phenotype and fewer secondary cytogenetic alterations than cMCL and aMCL. PARP1 protein expression and 13q14 deletion are associated with a progressive clinical course of lMCL and should be included in initial diagnostic studies as predictors of unfavorable outcome. PARP1 deletion is involved in lMCL pathogenesis and might confer advantage.

Abstract
BACKGROUND In Algeria, the data on infertility and its various causes are rare. Recently, the introduction of assisted reproduction has allowed expecting that 300000 couples, which represent 7% of couples of reproductive age, face difficulty conceiving a child. Knowing that most idiopathic cases are likely to be due to chromosomal abnormalities, we aimed to investigate genetic defects by karyotype analysis in Algerian infertile men, using peripheral blood lymphocytes. METHODS A cytogenetic study was conducted on 10 men from infertile couples by Karyotype analysis of R-banding performed by lymphocyte culture technique. Fluorescence in situ hybridization was performed and molecular abnormalities were investigated by polymerase chain reaction. Follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels were evaluated by immunoradiometric method. RESULTS Chromosomal abnormalities were observed in 30% of the patients. We identified a homogenous Klinefelter syndrome patient with 47, XXY karyotype, a mosaic Klinefelter syndrome patient with 47, XXY/46, XY karyotype and a 46, XX male. Fluorescence in situ hybridization showed that the sex-determining region Y was translocated to the short arm of the X chromosome in patient with 46, XX chromosomal constitution and the presence of the SRY gene was confirmed by polymerase chain reaction and electrophoresis. CONCLUSION The occurrence of chromosomal abnormalities in 30% of the infertile men strongly supports the inclusion of routine cytogenetic testing for diagnostic establishment and suitable counseling for couples seeking for assisted reproduction technologies.

Abstract
The present study was performed to determine whether the adherence to regular follow-up assessments using standardized real-time quantitative polymerase chain reaction (qPCR) and/or cytogenetic tests in Lebanese patients with chronic myeloid leukemia (CML) meet the European LeukemiaNet recommendations. The present study was a retrospective analysis of 34 patients diagnosed with chronic phase CML who had been treated with tyrosine kinase inhibitors and monitored with regular cytogenetic tests and/or measurement of the BCR-ABL transcript level at 3, 6, and 12 months from 2006 until 2015 in 3 university hospitals in Lebanon. All patients were included and monitored in an adherence program (SAWA program). The male/female ratio was 3:1. The median age was 50 years, and the mean age was 50 years. As frontline treatment, 29 patients started imatinib and 5 patients received second-generation tyrosine kinase inhibitors. We defined compliance to the monitoring tests as regulary realizing the qPCR at 3, 6, and 12 months. Of the 36 patients, 15 underwent the recommended tests at 3, 6, and 12 months, representing a compliance rate of 41.6%; 28 of the 34 patients underwent the recommended tests only twice in the first follow-up year. Only 14 patients underwent qPCR at 3 months. We believe that despite the inclusion of our patients in an adherence program, the compliance rate is still low. We also believe that greater effort is required to improve the adherence to regular follow-up examinations.

Abstract
Monoclonal B-cell lymphocytosis (MBL) is defined as a laboratory abnormality where small (<5 x 10(9)/L) clonal B-cell populations are detected in the peripheral blood of otherwise healthy subjects. According to the immunophenotype, MBL is labeled as chronic lymphocytic leukemia (CLL)-like (75% of cases), atypical CLL, and CD5-negative. Concentration of clonal B cells differentiates low- (LC) and high-count (HC)-MBL (< or ≥ 0.5 x 10(9)/L, respectively). Thanks to technical improvements, we are able to identify CLL-like clonal B-cell populations at increased frequency with age, but we are still far from understanding its relationship with clinically overt CLL. LC-MBL, requiring high-throughput screening technique to be identified in population studies, seems to be a bird of a different feather and several hints suggest that LC-MBL is related to aging and/or chronic antigenic stimulation. Immunogenetic, cytogenetic and genetic data support the notion that HC-MBL, usually identified in the clinical setting, is a premalignant condition and, based on biological parameters, it is frequently difficult to differentiate it from early stage CLL. The rapid improvement and widespread availability of cutting-edge technology, in particular next-generation sequencing (NGS), raises hope that we are getting closer to unveiling the fundamental nature of MBL and CLL and how they are related to each other.

Abstract
SET and MYND domain containing 2 (SMYD2) and the SET and MYND domain containing 3 (SMYD3) are the most studied and well-characterized members of SMYD family. It has been demonstrated that their altered expression is associated with the progression of several solid tumors. Nevertheless, whether these methyltransferases exert any impact in chronic lymphocytic leukemia (CLL) remains unknown. Here, we investigated the gene expression profile of SMYD2 and SMYD3 in 59 samples of CLL and 10 normal B cells. The obtained results were associated with white blood cells (WBC) and platelet counts, ZAP-70 protein expression, and cytogenetic analysis. We found that SMYD2 and SMYD3 are overexpressed in CLL patients and, interestingly, patients with residual expression of both genes presented a high WBC count and complex karyotype. Furthermore, a strong correlation between SMYD2 and SMYD3 gene expression was unveiled. Our data demonstrate the association of a residual expression of SMYD2 and SMYD3 with CLL progression indicators and suggests both genes are regulated by a common transcriptional control in this type of cancer. These results may provide the basis for the development of new therapeutic strategies to prevent CLL progression.

Abstract
INTRODUCTION Data from 51 patients (23 women) with chronic myeloid leukemia (CML) in blast phase (BP) were analyzed in order to identify prognostic factors for complete hematologic response (CHR) and survival. PATIENTS AND METHODS Forty-four patients experienced disease progression from chronic or accelerated phase, and 7 cases presented as CML-BP. Thirteen patients (25.5%) had extramedullary involvement at diagnosis, and 71% were myeloid BP. Clonal evolution was identified in 53% of the cases, and the abnormalities most frequently observed were isochromosome (17q), double Philadelphia chromosome, and trisomy 8. Forty-five patients received treatment: 60% chemotherapy (CT) alone and 40% CT plus tyrosine kinase inhibitors (TKI) or TKI alone; 42% of them experienced CHR. RESULTS Median overall survival (OS) in patients whose disease responded to treatment was 7 months (95% confidence interval, 1.7-6.2 months), with a median disease-free survival of 5 months (95% confidence interval, 2.8-5.8 months). One out of 3 patients who underwent hematopoietic stem-cell transplantation remains alive. Multivariate analysis revealed that lymphoid BP and TKI therapy had a statistically significant positive impact as prognostic factors for CHR. In the multivariate analysis, age > 60 years, hemoglobin < 10 g/dL, and complex karyotype were statistically significant negative prognostic factors for OS. There was no statistical significant difference in OS between patients who received only CT (1988-2002) with those treated with CT plus TKI (2003-2013). CONCLUSION This is the first study in Mexico to report prognostic factors associated with CHR and OS in patients with CML-BP.

Abstract
Myelodysplastic syndromes are heterogeneous diseases whose molecular characteristics have only been identified in recent years. Better identification of prognostic factors, larger access to allogeneic stem cell transplantation and the advent of new drugs notably hypomethylating agents (azacitidine, decitabine) and lenalidomide have improved patient outcome.
