Abstract
Patients with very early-onset inflammatory bowel disease (VEO-IBD) may present because of underlying monogenic inborn errors of immunity (IEI). Strong differences have been observed in the causes of monogenic IBD among ethnic populations. This multi-center study was carried out on 16 Iranian patients with VEO-IBD. We reviewed clinical and basic immunologic evaluation including flow cytometry and immunoglobulin levels. All patients underwent clinical whole exome sequencing (WES). Sixteen patients (8 females and 8 males) with a median age of 43.5 months were enrolled. The median age at the onset of symptoms was 4 months. Most patients (12, 75%) had consanguineous parents. Chronic non-bloody diarrhea (13, 81.3%) and perianal diseases including perianal abscess (6, 37.5%), anal fissure (6, 37.5%), or anal fistula (2, 12.5%) were the most common manifestations. WES identified a spectrum of genetic variants in 13 patients (81.3%): IL10RB (6, 37.5%), MVK (3, 18.8%), and CASP8, SLC35C1, G6PC3, and IKBKB in one patient, respectively. In 3 patients (18.7%) no variant was identified. Flow cytometry identified a spectrum of abnormalities that helped to assess the evidence of genetic diagnosis. At the end of the survey, 3 (18.8%) patients were deceased. This high rate of monogenic defects with a broad spectrum of genes reiterates the importance of investigating IEI in patients with infantile-onset IBD.

Abstract
BACKGROUND In April 2020, an association between multisystem inflammatory syndromes (MIS-C) was observed in children with severe acute respiratory syndrome coronavirus infection (SARS-CoV-2). Most patients had heart involvement alone, and most patients had pericardial effusion. This study aimed to express and emphasize cardiac involvement in pediatric patients with respiratory symptoms who were diagnosed with COVID-19. METHODS This study was conducted in July 2021 in Kerman province, Southeastern Iran, during a notable surge in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections. The study included 904 pediatric patients diagnosed with COVID-19. Data collection involved a comprehensive assessment of clinical symptoms and manifestations. Patients with fever lasting more than five days were admitted to the hospital. Echocardiography was utilized for cardiac involvement diagnosis, with 47 patients undergoing this diagnostic procedure. RESULTS Of the 904 patients, most of them had high fevers (74%). Fifty-five patients had a fever for more than five days and were hospitalized. Of the 47 patients who underwent echocardiography, 45 (81%) had heart involvement. In 75% of patients, pericardial effusion was the only cardiac involvement. Patients with pericardial effusion were treated with dexamethasone up to 3 mg every 8 h for 72 h. CONCLUSIONS MIS-C has a wide range of clinical symptoms. In cases where the fever is prolonged and there are gastrointestinal symptoms, physicians have clinical suspicion to diagnose this syndrome. Most cases of pericardial effusion are alone and improve with treatment with glucocorticosteroids.

Abstract
Programmable nucleases are powerful genomic tools for precise genome editing. These tools precisely recognize, remove, or change DNA at a defined site, thereby, stimulating cellular DNA repair pathways that can cause mutations or accurate replacement or deletion/insertion of a sequence. CRISPR-Cas9 system is the most potent and useful genome editing technique adapted from the defense immune system of certain bacteria and archaea against viruses and phages. In the past decade, this technology made notable progress, and at present, it has largely been used in genome manipulation to make precise gene editing in plants, animals, and human cells. In this review, we aim to explain the basic principle, mechanisms of action, and applications of this system in different areas of medicine, with emphasizing on the detection and treatment of parasitic diseases.

Abstract
Background: It is well established that upper and lower airways are often clumped together when diagnosing and treating a disease. This study was designed to determine the prevalence of upper and lower airway diseases and to assess the effect of sociodemographic factors on the prevalence and the comorbidity of these disorders. Methods: This cross-sectional population-based study included patients with ages ranging between 15 to 65 years, who were referred to allergy outpatient clinics in various provinces of Iran from April to September 2020. A modified global Allergy and Asthma European Network (GA2LEN) screening questionnaire was filled out by local allergists of the 12 selected provinces in Iran. Information about the patients and sociodemographic factors was also recorded. Statistical analysis was done by univariate statistical analyses and multiple logistic regressions in SPSS software Version 26. Results: Out of 4988 recruited patients, 1078 (21.6%) had the symptoms of allergic rhinitis (AR) and 285 (5.7%) met the criteria of asthma. The prevalence of acute rhinosinusitis (ARS) and chronic rhinosinusitis (CRS) was 21.6 % and 22%, respectively. The highest prevalence of AR and ARS was in Tehran with the arateof of 33.9% each. Asthma was more prevalent in Khuzestan (14.2%) and CRS in Baluchestan (57.5%). Our analysis showed that the patients with asthma were most likely to have other allergic diseases as well-CRS (OR = 4.8; 95% CI, 2.02- 5.82), AR (OR= 2.5, 95% CI, 2.10-3), ARS (OR = 1.8; 95% CI, 2.10-3), followed by eczema (OR = 1.4; 95% CI, 1.13-1.67).We found that those individuals with CRS were most likely to have painkiller hypersensitivity (OR= 2.1; 95% CI, 1.21-3.83). Furthermore, smoking has been found more than 1.5 folds in patients with ARS. After adjusting variables, there was no correlation between education, occupation, and ethnicity with the studied diseases. Conclusion: Rhinosinusitis is a common condition among Iranian patients. This study confirmed that inflammation of the upper and lower airways can occur simultaneously. Gender, education, occupation, and ethnicity were found to be irrelevant in the development of either AR, asthma, ARS, or CRS.

Abstract
Abstract
Background
Inflammation during pregnancy including elevated C-reactive protein (CRP) is associated with adverse pregnancy outcomes. Understanding relationships between CRP and modifiable factors such as dietary patterns is key to identifying opportunities for pregnancy intervention. This study assessed change in adherence to the Dietary Approaches to Stop Hypertension (DASH) and Mediterranean diet (MED-diet) from early to late-pregnancy and the relationship between adherence to both dietary patterns at early-pregnancy with plasma CRP at early and late-pregnancy.
Methods
Women (n = 215) attending antenatal clinics at Monash Health, Melbourne were recruited at 10-20 weeks gestation. Medical history and blood samples were collected at 5 antenatal visits. Adapted DASH and MED-diet scores were calculated from Food Frequency Questionnaires completed at early ([mean±SD] 15±3 weeks) and late (36±1 week) pregnancy. CRP was measured in maternal plasma samples collected at early and late-pregnancy. Adjusted linear regression assessed associations of early-pregnancy DASH and MED-diet scores with early and late-pregnancy plasma CRP.
Results
DASH score at early (23.5±4.8) and late (23.5±5.2) pregnancy was not significantly different (p = 0.971). There was no statistically significant change in MED-diet score from early (3.99±1.6) to late-pregnancy (4.08±1.8) (p = 0.408), however, MED-diet adherence and plasma CRP at early pregnancy were significantly and inversely associated (β= -0.14 [95%CI= -0.27, -0.01], p = 0.039).
Conclusions
Adherence to the MED-diet in early pregnancy may be beneficial in reducing inflammatory markers and assisting optimal pregnancy outcomes. Assessment of dietary patterns is important to assist identifying modifiable factors which impact maternal and child health.

Abstract
Background:
The coronavirus disease 2019 (COVID‐19) was first reported in December 2019 in Wuhan, China. Skin manifestations of COVID-19 have been reported sporadically. Staphylococcus aureus occurs after viral infection due to unregulated IFN-α. We designed this reported case to pay more attention to the rare skin manifestations following COVID-19.
Case Report:
The patient was a 12-months-old girl who presented with fever and skin rashes. Two days before admission, erythematous rashes spread around the mouth, nose, eyes, and trunk. Erythematous lesions begin to peel the next day. RT-PCR of the nasopharynx was positive for COVID-19. Treatment with vancomycin and clindamycin was started. The patient was discharged with complete recovery of skin lesions.
Conclusion:
One of the early manifestations of COVID-19 in children can be fever and rash. Clinical suspicion led to more attention to complications of bacterial superinfection such as staphylococcal scalded skin syndrome.

Abstract
OBJECTIVE The current study was designed to investigate the effects of some nucleoside reverse transcriptase inhibitors (NRTIs) on HSV-1 infection. MATERIALS AND METHODS Initially, the SwissTargetPrediction server was used to predict the interactions between HSV-1 thymidine kinase and acyclovir, stavudine, zidovudine, didanosine, and entecavir. The effect of each component on Vero cell viability was assessed by the MTT assay. After treatment, the cell supernatants were collected, and HSV-1 replication was analyzed by quantitative real-time PCR. RESULTS The qPCR results revealed that viral titers were reduced 41, 40, 19, 44, and 31-fold in the presence of acyclovir, zidovudine, stavudine, didanosine, and entecavir, respectively. CONCLUSIONS Our findings indicate that NRTIs significantly reduce HSV-1 replication in cell culture.

Abstract
BACKGROUND The maintenance of postural control is a key component in dynamic physical activity, especially during muscle fatigue and against external forces. Despite many studies in this field, there is no consensus regarding the effects of plantar flexor muscles fatigue on postural control during different postural tasks. OBJECTIVE To evaluate the effects of plantar flexor muscles fatigue on postural control during quiet stance and external perturbation in healthy subjects. MATERIAL AND METHODS Twenty four healthy individuals (20-35 years) participated this interventional study. The foot center of pressure data was measured using a single force platform, and then the postural control parameters, including the center of pressure displacement and velocity in the anterior-posterior and medial-lateral direction and also path length calculated under two conditions; quiet and perturbed stance, before and after plantar flexor muscles fatigue. RESULTS The statistical analysis demonstrated that mean displacement and velocity of the center of pressure in the anterior-posterior direction and also path length increased after the fatigue protocol in the perturbed condition. However, fatigue had no significant effects on postural control parameters in the quiet standing condition. CONCLUSION These results indicated that the effects of muscle fatigue on postural control depend on the difficulty of the task and the relevance of proprioceptive information. The postural control system appears to use distinct control strategies in different situations such as quiet and perturbed stance conditions, and these strategies may be differentially altered by fatigue. In conclusion, due to the potential risk of loss of balance, it is important to take the role of plantar flexor muscle fatigue into account during more difficult postural tasks.

Abstract
BACKGROUND Chronic low back pain (CLBP) disability has been particularly frustrating because its treatment has been a great therapeutic challenge. Disability has been suggested to depend on different factors that should be found and considered in the medical management. The inter-segmental coordination is often impaired in CLBP subjects; however, to the best of our knowledge, there is no evidence about the relationship between the existence of coordination problems and disability in CLBP patients. OBJECTIVE To evaluate the correlation between sagittal plane trunk-pelvis inter-segmental coordination parameters during walking and disability level in CLBP patients. METHODS Kinematic data were collected from 16 non-specific CLBP (18-40 years) volunteers during walking. Sagittal plane time-normalized segmental angles and velocities were used to calculate continuous relative phase for each data point. Coordination parameters, mean absolute relative phase (MARP) and deviation phase (DP) were derived to quantify the trunk-pelvis coordination pattern and variability during gait cycles, respectively. The disability level was quantified through Oswestry Disability Index (ODI) questionnaire. Pearson correlation coefficient was used to find the probable correlation between coordination parameters and disability level. RESULTS The analysis demonstrated a significant correlation between sagittal plane MARP or DP and disability level (%ODI) in CLBP subjects during walking (r= -0.806 P<0.001 and r= -0.856, P<0.001, respectively). CONCLUSION This study demonstrated that the lower the MARP (more in-phase pattern) and DP (less variable pattern) in the CLBP subjects, the more disability existing in such patients. The results suggest that clinicians should look beyond pain management when prescribing rehabilitation for CLBP and consider interventions that target segmental coordination improvement to manage CLBP induced disability.

Abstract
BACKGROUND Diabetes mellitus (DM) is considered as an important health confounder in our world, which necessitates its better management by new methods. In this study, we have evaluated the effects of oral Arnebia Euchroma (AE) extract on different stereological parameters of the pancreas as well as blood glucose in Streptozotocin (STZ)-induced diabetes in rats. METHODS We divided 48 Wistar rats into 4 groups: C1 including normal rats, C2 not-treated diabetic rats, E1 with diabetic rats receiving 100 mg/kg AE extract orally, and E2 including diabetic rats treated with 300 mg/kg AE extract. Stereological study was done and the levels of blood glucose were also estimated and compared between experimental and control groups. RESULTS There were significant differences in volumes of pancreatic islets, β cell populations, blood glucose levels in AE treated groups compared with not-treated diabetic group. CONCLUSION Although AE did not completely prevent or heal the pancreatic damage, its oral administration showed promising effects on maintaining the population of beta cells, the main insulin secreting cells, after STZ-induced injury and also lowered blood glucose levels compared to the not-treated diabetic group.

Abstract
Infertility affects up to 15% of reproductive-aged couples worldwide, with male factor being detected in 40%-50% of the cases. Proper sperm production is associated with the establishment of appropriate epigenetic marks in developing germ cells. Several studies have demonstrated the association between abnormal spermatogenesis and epigenetic disturbances with the major focus on DNA methylation. Imprinted genes are expressed in a parent-of-origin-specific manner, and the role of their DNA methylation in proper spermatogenesis has been documented recently. The existing evidence along with the absence of relevant data in south of Iran prompted us to study the methylation of H19 imprinted gene in spermatozoa of idiopathic infertile patients (males with abnormalities in sperm parameters) and healthy controls by Combined Bisulfite Restriction Analysis. According to our results, the lowest methylation percentage of H19 imprinted gene belongs to three cases with sperm characteristics under normal range (two cases Oligoasthenoteratozoospermia and one case Oligoteratozoospermia). However, our results show that the median of methylation percentage for H19 is not statistically significant between case and control groups. Our results and those of others introduce DNA methylation as a potential marker of fertility and should be investigated with more patients in future studies.

Abstract
Soil and ground water resource pollution by petroleum compounds and chemical solvents has multiple negative environmental impacts. The aim of this research was to investigate the impacts of kerosene and gas oil pollutants on some physical and chemical properties, breakthrough curve (BTC), and water retention curve (SWRC) of silty clay soil during a 3-month period. Therefore, some water-saturated soils were artificially contaminated in the pulse condition inside some glassy cylinders by applying half and one pore volume of these pollutants, and then parametric investigations of the SWRC were performed using RETC software for Van Genukhten and Brooks-Corey equations in the various suctions and the soil properties were determined before and after pollution during 3 months. The results showed that gas oil and kerosene had a slight effect on soil pH and caused the cumulative enhancement in the soil respiration, increase in the bulk density and organic matter, and reduction in the soil porosity and electrical and saturated hydraulic conductivity. Furthermore, gas oil retention was significantly more than kerosene (almost 40%) in the soil. The survey of SWRC indicated that the contaminated soil samples had a little higher amount of moisture retention (just under 15% in most cases) compared to the unpolluted ones during this 3-month period. The parametric analysis of SWRC demonstrated an increase in the saturated water content, Θ s, from nearly 49% in the control sample to just under 53% in the polluted ones. Contaminants not only decreased the residual water content, Θ r, but also reduced the SWRC gradient, n, and amount of α parameter. The evaluation of both equations revealed more accurate prediction of SWRC's parameters by Van Genukhten compared to those of Brooks and Corey.

Abstract
Nonsyndromic cleft lip with or without palate (CL/P) is thought to be caused by the interplay of genetic and environmental factors, and this has thus hindered the process of identifying genetic causative factors. Numerous studies in the past decade have implicated IRF6 in CL/P, but this has not often been replicated in other populations. In specific, the only etiologic single-nucleotide polymorphism (SNP) identified in the IRF6 locus (rs642961) has recently been shown not to be associated with CL/P in diverse populations. We therefore used a genewide tagging SNP (tagSNP) haplotyping approach (including rs642961 as a tagSNP) to detect all potential risk-conferring haplotypes and combined this with detailed subphenotyping of CL/P cases ( N = 150) according to severity. We observed a significant overrepresentation of a tagSNP haplotype carrying the rs642961 risk allele in the most severe subphenotype of CL/P (complete bilateral CL/P; P = 0.008, odds ratio = 4.97, 95% confidence interval = 1.33 to 18.46). It was recently shown that >80% of IRF6 mutations in syndromic CL/P occur on the same haplotype background. We therefore suggest that IRF6 is a marker of CL/P severity.

Abstract
BACKGROUND Bone healing and its reconstruction in fractures, especially in long bones are of particular importance in regenerative medicine. This study compares the bone healing rate after a human xenograft of mineralized bone and together with an allograft of bone marrow mesenchymal stem cells (MSCs) in an experimental tibial bone fracture rabbit model. METHODS In fall 2009, twenty New Zealand white rabbits were randomly divided into 2 equal groups. In both groups, a 5 mm segmental defect was created in the right tibia. In group A, a scaffold pin was seeded with allogenic rabbit MSCs and was placed in the defect area and in group B, the defect was filled with an unseeded pin human mineralized bone xenograft. An untreated defect was induced in the left tibia of all animals serving as the control. After 4-8 weeks, the segmental defects were histologically evaluated and also by a compressive test. RESULTS In groups A and B, healing and formation of new bony tissue were significantly more than the control group and with a significant less inflammation. CONCLUSION Tissue engineering of mineralized bone xenograft and MSCs allograft may be significant steps in bone healing and regenerative medicine.

Abstract
BACKGROUND Finding more efficient agents with fewer side effects for treatment of burns has always been a concern for researchers. Silver sulfadiazine (SSD), apparently due to its antimicrobial effect, is still one of the most common prescribed agents. Previous studies suggested that Arnebia euchroma (AE) has shown antimicrobial and anti-inflammatory activities. This study investigates the healing effect of AE extract in comparison with SSD in second degree burn wounds. METHODS Fort eight female Wistar rats (220±20 g) were divided into four groups. Standard second degree burn wounds were induced on the back of their necks. One group was treated with SSD; two groups were treated with AE cream at concentrations of 10% (AE10) and 20% (AE20) and the control group which received no treatment. The duration of treatment was 28 days. RESULTS This study revealed that AE and SSD noticeably improved re-epithelization, fibroblasts proliferation, and collagen bundle synthesis and had a noticeable anti-inflammatory effect compared with the control group. CONCLUSION Results of the present study revealed that Arnebia euchroma herbal extract was an effective treatment for second degree burn wounds when compared with SSD.

Abstract
IntroductionADHD is one of the most prevalent psychiatric disorders in children.ObjectiveADHD have co-morbidity with many other psychiatric disorders.AimsAim of this study was Comparing of prevalence of three subtypes of ADHD with psychiatric Co- morbidity in primary school students of Arak-Iran.MethodsThis study was a descriptive analytic, cross- sectional one, which carried on 2000 (960 girls and 1040 boys)primary school students in 1st state of Arak in academic year of 2009–2010, which screened by Intelligence Raiven scale and 48 Canner’s questionnaire (parents and teachers)and if there were existed of any subtypes of ADHD, we have done K-SADS-E questionnaire(Schedule for Affective disorder and Schizophrenia -epidemiological version)for them, then data were analyzed by using descriptive- statistical methods and Logistic- regression for obtaining R. R.Results2.3, 3.5 and 2.7 percent of children have one of the subtypes of ADHD. The findings showed that prevalence of hyperactivity and attention deficit subtypes decreased while combined type increased by increasing age. The prevalence of two subtypes of hyperactivity and attention deficit in boys and girls were not significantly different but combined type was significantly different. Finally, there were differences between ADHD subtypes and Co morbidity of psychiatric disorders such as conduct, depressive,enuresis, tic, schizophrenia, oppositional, obsessive- compulsive, manic and social phobia, but these differences were not significant between girls and boys.ConclusionsPrevalence of subtypes of the ADHD were different between age and gender but there were not significant differences between Co morbidity of ADHD subtypes and psychiatric disorders.

Abstract
An antigen-based ELISA system was evaluated for diagnosis of visceral leishmaniasis (VL). Urine samples from confirmed VL cases were tested by the system in comparison with urine samples from patients with non-VL infectious disease and patients with non-infectious diseases. Antigen was detected in urine of 21 out of 35 (60%) of VL cases. No cross reaction was found with samples from healthy individuals except in 3 samples from non-VL infectious diseases. Two samples from cutaneous leishmaniasis patient and one from patient with toxoplasmosis. The results obtained with the antigen-based ELISA were compared to those obtained with direct agglutination test (DAT), an antibody-based ELISA and indirect immunofluorescent antibody (IFA) revealed that the antigen-based ELISA is comparable in terms of specificity (91.2%; 95% CI=75.2-97.7%) but with a lower sensitivity (60%; 95% CI=42.2-75.6%). These results suggest that the antigen detection in urine by the noninvasive antigen-based ELISA system might offer a useful method for diagnosis of VL.

Abstract
The study was conducted to determine the effect of Azotobacter chroococcum (Azotobacter) application on quality and quantity forage of the rapeseed cultivars (RGS 003, Hyolla 401 and Hyolla 330) and the possibility of cultivation the rapeseed forage in summer. The experimental design was spilt plot laid out in randomized complete block with three replications. Different levels of Azotobacter (zero and one kg hal) and cultivars were randomized to main plot and sub plot units, respectively. Results showed that Azotobacter significantly affected on all quantity traits except plant height. There were significant differences among cultivars for dry matter, biomass, sub branch number, plant height and forage glucosinolate concentration. Therefore Azotobacter can be considered as growth promoting for rapeseed in the future studies. Also, RGS003 cultivar was better than other cultivars when Azotobacter was applied.

Abstract
1. The aim of present study was to investigate the effects of magnesium (Mg) on cardiac function and infarct size and to compare it effects with those of adenosine. The mechanism of Mg-mediated cardioprotection was explored by combined use of Mg and a selective adenosine A(1) receptor antagonist. 2. Rat isolated hearts were used for Langendorff perfusion. Hearts were either non-preconditioned or preconditioned with Mg (6 mmol/L) or adenosine (1 mmol/L) before 30 min sustained ischaemia followed by 120 min reperfusion. Within each of these protocols, hearts were divided into two groups; one group was exposed to the A(1) receptor antagonist 8-cyclopentyl-1,3-dipropylxanthine (DPCPX; 200 nmol/L). Infarct size was measured by the triphenyltetrazolium chloride method. Left ventricular function was assessed by left ventricular developed pressure (LVDP), the product of heart rate x LVDP and coronary flow (CF). 3. The administration of Mg had an anti-infarct effect independent of its effect on postischaemic functional recovery in rats. Both Mg and adenosine equipotently reduced infarct size, but this effect of Mg was not blocked by the simultaneous administration of DPCPX. Cardiac function was improved by both adenosine and Mg and blockade of adenosine A(1) receptors attenuated these effects for both agents. 4. In conclusion, the results of the present study indicate that stimulation of adenosine A(1) receptors is not responsible for the anti-infarct effect of Mg in ischaemic myocardium in rats, but that the Mg-mediated protection of postischaemic functional recovery in rats is mediated by these receptors.

Abstract
In this study, the feasibility and engineering aspects of acidophilic ferrous iron oxidation in a continuous biofilm airlift reactor inoculated with a mixed culture of Acidithiobacillus ferrooxidans and Leptospirillum ferrooxidans bacteria were investigated. Specific attention was paid to biofilm formation, competition between both types of bacteria, ferrous iron oxidation rate, and gas liquid mass transfer limitations. The reactor was operated at a constant temperature of 30 degrees C and at pH values of 0-1.8. Startup of the reactor was performed with basalt carrier material. During the experiments the basalt was slowly removed and the ferric iron precipitates formed served as a biofilm carrier. These precipitates have highly suitable characteristics as a carrier material for the immobilization of ferrous iron-oxidizing bacteria and dense conglomerates were observed. Lowering the pH (0.6-1) resulted in dissolution of the ferric precipitates and induced granular sludge formation. The maximum ferrous iron oxidation rate achieved in this study was about 145 molFe(2+)/m(3).h at a hydraulic residence time of 0.25 h. Optimal treatment performance was obtained at a loading rate of 100 mol/m(3).h at a conversion efficiency as high as 98%. Fluorescent in situ hybridization (FISH) studies showed that when the reactor was operated at high ferrous iron conversion (>85%) for 1 month, the desirable L. ferrooxidans species could out-compete A. ferrooxidans due to the low Fe(2+) and high Fe(3+) concentrations.

Abstract
Murine Sipa-1 (signal-induced proliferation associated protein) is a mitogen induced GTPase activating protein (GAP). While mapping candidate genes for multiple endocrine neoplasia type 1 (MEN1) at 11q13, we cloned the human homologue of Sipa-1. Herein, we report the complete cDNA sequence, expression, and genomic organization of SIPA-1. SIPA-1 consists of 16 exons with highly conserved exon-intron boundaries. The predicted SIPA-1 protein is highly homologous to the mouse protein, particularly in the region of the GAP-related domain at the amino terminus and the leucine zipper at the carboxy terminus. It is widely expressed, including in fetal tissues, but is most highly expressed in lymphoid organs. During the course of cloning SIPA-1, the MEN1 gene was identified, thus excluding human SIPA-1 as a candidate for this disease.

Abstract
A transcription map of a 1200-kb region encompassing the MEN1 locus was constructed by direct cDNA selection and mapping ESTs. A total of 29 genes were mapped. Ten transcripts were identified by cDNA selection of a focused 300-kb genomic region telomeric to the MEN1 consensus region. Since many of the sequences cloned by cDNA selection also identified ESTs from the region, 19 additional RH-mapped ESTs were mapped to the entire contig region by PCR amplification of genomic clones. Nine known genes, 2 putative human homologues to mouse genes, and 18 novel transcripts map to the region. Transcripts that map to the MEN1 interval PYGM-D11S449 include SGC35223, IB1256, AA147620, ZFM1, FAU, and CAPN1. The latter 3 known genes have already been excluded as candidate MEN1 genes. The 2 putative human homologues of mouse genes Ltbp2 and Spa-1 may be candidate tumor suppressor genes, but they map telomeric to D11S449. Although both of these genes map outside the MEN1 consensus region they may play a role in sporadic endocrine tumors independent of the MEN1 gene or in other tumors, such as breast cancer, that have loss of heterozygosity within this region.

Abstract
Immunophenotypic analysis of acute leukemias is time consuming and often requires flow cytometric analysis. A 1-hour alkaline phosphatase-labeled streptavidin-biotin immunocytochemical procedure was evaluated as an alternative. Seventeen cases of acute leukemia, including 10 acute lymphocytic (ALL) and 7 acute nonlymphocytic, were phenotyped by the rapid immunocytochemical procedure and the results were compared with standard analyses. In all 17 cases, the diagnoses made using standard cytochemical and immunologic methods were the same as obtained in blinded reviews by rapid immunocytochemical analysis. Nine cases of precursor B-cell ALL were positive for CD19 and/or CD22. Five CD19 + cases of ALL reacted with anti-myeloperoxidase, with one case also positive for CD15. CD15 positivity was confirmed on repeated study as well as with plastic section immunoperoxidase staining. Nine cases of ALL were positive for CD10 and eight were positive for terminal deoxynucleotidyl transferase. One case of ALL marked as T-cell ALL with CD1, CD2, CD3, and CD7. All cases of acute nonlymphocytic leukemia were positive for CD15, CD13, and/or CD33; anti-myeloperoxidase was positive in all but one case of monocytic leukemia. All cases of acute nonlymphocytic leukemia were negative for CD10 and one was positive for terminal deoxynucleotidyl transferase. Acute leukemias apparently may be phenotyped easily and accurately in 1 hour with this immunocytochemical technique, and slides may be stored permanently for review. There was in these 17 cases high correlation of the diagnoses with standard flow cytometric and cytochemical results. This rapid method allows a coordinated evaluation of morphologic features and immunophenotype; the latter features facilitated confirmation of unexpected reactivity of myeloid markers CD15 and MPO-7 in some cases of ALL.

Abstract
We studied 32 transverse left ventricular slices of myocardium from 16 pigs after 45 to 100 minutes of coronary artery occlusion followed by 180 minutes of reperfusion. Infarct area for each slice was determined as follows: (1) grossly, by triphenyl tetrazolium chloride staining of each slice, and (2) microscopically, by complete histologic sectioning of the triphenyl tetrazolium chloride-stained surface of each slice. Planimetry of necrotic and nonnecrotic areas was performed from tracings and photographs of triphenyl tetrazolium chloride-stained slices and from actual histologic sections. When triphenyl tetrazolium chloride and histologic measurements were compared, necrotic tissue area had decreased 11.4% +/- 15.0% (2.59 +/- 1.04 vs 2.09 +/- 0.86 cm2). Nonnecrotic tissue area decreased 20.6% +/- 24.0% (8.31 +/- 3.79 vs 5.16 +/- 2.73 cm2). In this model of ischemia followed by reperfusion, with fixation and processing, viable tissue shrank almost twice as much as necrotic tissue. This differential shrinkage introduces an error resulting in overestimation of infarct size by histologic quantitation.
