Abstract
This study aimed to examine the relationship between type 2 diabetes mellitus (T2DM) and renin-angiotensin system gene polymorphisms in the Iranian population. Additionally, we performed a straightforward meta-analysis of the present articles to better understand this role. A total of 100 Iranian individuals, 50 patients with T2DM, and 50 age-matched healthy individuals were included in this study. DNA was extracted using the salting-out approach, polymerase chain reaction was used to amplify the angiotensin-converting enzyme (ACE) gene, electrophoresis techniques were used, and genotyping was performed. We also searched PubMed, Web of Science, Scopus, and Google Scholar databases for papers published in 2023. We found a significantly higher frequency of I/D genotype in the patient group than in the control group, and the risk of T2DM was 10 times higher in individuals with the I/D genotype (OR, 10 [95% CI, 3.7 to 27]; p < 0.0001) and also 2.85 time higher in individuals with the D allele OR, 2.85 [95% CI, 1.55 to 5.24]; p < 0.001). The ACE polymorphism alleles D and I/D genotypes may increase the risk of developing T2DM in an Iranian population.

Abstract
Breast cancer is a complex malignancy with diverse molecular and cellular subtypes and clinical outcomes. Despite advances in treatment, breast cancer remains a significant health challenge. However, recent advances in cancer immunotherapy have shown promising results in the treatment of breast cancer, particularly the use of inhibitors that target the immune checkpoint PD1/PDL1. Also, the cGAS-STING pathway, an important part of the innate immune response, has been considered as a major potential therapeutic target for breast cancer. In this narrative review, we provide an overview of the cGAS-STING and PD1/PDL-1 pathway in breast cancer, including their role in tumor development, progression, and response to treatment. We also discuss potential future directions for research.

Abstract
Colorectal cancer (CRC) is a common and deadly form of cancer, leading to the need for new therapeutic targets and strategies for treatment. Recent studies have shown the cGAS-STING pathway to be a promising target for cancer therapy. The cGAS-STING pathway is a part of the innate immune system and serves to identify DNA damage and viral infection, promoting an immune response. Activation of this pathway leads to the production of immune mediators, such as type I interferons, that activate immune cells to attack cancer cells. Research has identified the cGAS-STING pathway as a frequently dysregulated component in CRC, promoting tumor growth and metastasis, or leading to chronic inflammation and tissue damage. The modulation of this pathway presents a potential therapeutic approach, either activating or inhibiting the pathway to enhance the immune response and prevent inflammation, respectively. Developing drugs that can modulate the cGAS-STING pathway offers promise for improving treatment outcomes for CRC patients. The present review explores recent research on the role of cGAS-STING in CRC and highlights the potential therapeutic benefits of targeting this pathway.

Abstract
PURPOSE Doxorubicin (DOX) is a common chemotherapeutic agent, with toxic side effects, and chemoresistance. Combination chemotherapy is a successful approach to overcome these limitations. Here, we investigated the effects of pioglitazone (PGZ), a PPARγ agonist, and/or DOX on the viability, cell cycle, apoptosis on THP-1 cells and normal human monocytes (NHMs). METHODS MTT assay was used to evaluate the cytotoxicity of DOX and/or PGZ. Cell cycle progression and apoptosis induction were examined by PI or Annexin V-PI double staining, and analyzed by flow cytometry. Quantitative RT-PCR was used to evaluate the changes in the mRNA expression of cell cycle progression or apoptosis-associated genes including P27, P21, CDK2, P53, BCL2 and FasR. RESULTS DOX, PGZ and DOX + PGZ exerted their cytotoxic effects in a dose- and time-dependent manner with low toxicity on NHMs. The cell growth inhibitory effects of DOX were in association with G2/M arrest, while PGZ executed S phase arrest. PGZ treatment enhanced G2/M among DOX-treated combinations with moderate elevation in the S phase. DOX, PGZ and combined treatments induced apoptosis (mostly late phase) in a dose-dependent manner. All treatments resulted in the significant overexpression of p21, p27, p53 and FasR genes and downregulation of CDK2. DOX + PGZ combined treatments exhibited the most significant changes in mRNA expression. CONCLUSION We demonstrated that the antiproliferative, cell cycle regulation and apoptosis-inducing capacity of DOX was enhanced by PGZ in THP-1 leukemia cells in a dose-dependent manner. Therefore, the combination of DOX + PGZ could be used as a novel combination to target AML.

Abstract
Breast cancer is one of the leading causes of cancer mortality. Growing evidence indicates that interleukins and its polymorphisms are involved in the pathogenesis of breast cancer. Variable number of tandem repeat (VNTR) polymorphism can affect transcription rate, mRNA stability and also the resulting protein expression and activity. Hence, present study aimed to assess the possible association between interleukin-1 receptor antagonist (IL-1Ra) VNTR polymorphism, and breast cancer susceptibility in Iranian population. A total of 300 Iranian individuals, 150 breast cancer patients and 150 age-matched healthy women, were included in this study. DNA extracted by salting out method and genotyping was done using the polymerase chain reaction. The frequency of the allele 2(5% vs. 22%) and the 2/2 genotype (22% vs. 46%) of IL-1Ra VNTR polymorphism was significantly higher in healthy control compared to breast cancer patient: therefore, A2 allele may play a protective role against breast cancer and its progression (p = .0001 and OR = 0.105, 95% CI: [0.044-0.248]). The allele 2 and 2/2 genotype of the IL-Ra VNTR polymorphism can be a protective factor against breast cancer susceptibility.

Abstract
Human leukocyte antigen-G (HLA-G) has immune-modulatory functions. Although the role of genetic variant HLA-G (rs1063320) in susceptibility to human papillomavirus (HPV) infection has been widely considered, it is still a matter of discussion. In order to shed light on the issue, we, therefore, conducted a meta-analysis to evaluate the common impact of the HLA-G (rs1063320) variant on susceptibility to HPV infection. Subsequently, the distribution of genotypes, genotyping techniques and ethnicity groups was collected, and general analyses were performed. A total number of five studies with 953 cases and 877 controls were found to meet our criteria. The polymorphism of HLA-G (rs1063320) was evaluated. This is the first meta-analysis to explore the connection between the HLA-G 3' UTR + 3142C/G (rs1063320) genetic variant and the risk of HPV infection. Our results showed no association between the variant of HLA-G 3' UTR + 3142C/G (rs1063320) and susceptibility to HPV infection in studied target populations.Impact StatementWhat is already known on this subject? Human papillomavirus (HPV) is the most widespread sexually transmitted infection in both men and women all over the world. It is correlated with prominent load of diseases and malignancies, including anogenital warts and anogenital and oropharyngeal cancers. In recent years, several studies manifested that different SNPs located on special genes seems to influence HPV infection risk.What the results of this study add? Our findings disclosed no relation between the variant of HLA-G 3' UTR + 3142C/G (rs1063320) and vulnerability to HPV infection in the target individuals.What are the implications of these findings for clinical practice and/or further research? The findings in current survey may offer a basis for further study on HLA-G variant in future investigation.

Abstract
Background: Several single-nucleotide polymorphisms (SNPs) in IL1B genes have been associated with KTCN. However, the results of these studies were not conclusive. This meta-analysis association study is aimed to quantitatively estimate the association of IL1B rs16944 (g.4490T>C) and rs1143627 (g.4970C>T), and IL1A rs2071376 (c.615 + 169C>A) polymorphisms with KTCN susceptibility.Materials and Methods: Systematic literature search was performed in Web of Science, MEDLINE, PubMed, Scopus, and Google Scholar databases. The odds ratios (ORs) and 95% confidence intervals (CI) were calculated assuming different contrasted genetic models.Results: The reference T allele of IL1B (g.4490T>C) polymorphism was significantly associated with decreased KTCN risk under all assessed genetic models. Regarding the reference C allele of IL1B (g.4970C>T) polymorphism, decreased risk of KTCN was found. The reference C allele of IL1A (c.615 + 169C>A) polymorphism conferred a decreased risk of KTCN under heterozygous codominant (AC vs. AA), homozygous codominant (CC vs. AA), and dominant (AC+CC vs. AA) genetic models. The pooling estimates showed that the T C haplotype was associated with a significant increase in KTCN risk. In contrast, the T T haplotype was correlated with a decreased risk of KTCN. With the assumption of a prior probability of 0.25, the false-positive report probability (FPRP) values were less than 0.2, indicating the observed significant associations were notable.Conclusion: These findings propose that the studied IL1B polymorphisms and the IL1A variation have opposite effects on KTCN susceptibility. More large-scale replication studies are warranted to illuminate the precise role of these SNPs on the etiology of eye disorders.

Abstract
BACKGROUND Single-Nucleotide Polymorphisms (SNPs) in genes responsible for coding microRNAs (miRNAs) are shown to be crucial in progression of Breast Cancer (BC). OBJECTIVE The purpose of this meta-analysis is to obtain more definitive and reliable results due to the ambiguity and inconsistency of the previous findings in this regard. This study aimed at clarifying the association of mir14a polymorphisms with breast cancer. METHODS We searched PubMed, EMBASE, Web of Science and Google Scholar databases for papers published before August 10, 2019. Afterward, genotypes' distribution, genotyping methods and ethnicity groups were extracted and Overall analyses were conducted. A total number of seventeen researches on 7676 subjects and 7476 controls were found to meet our criteria in this meta-analysis. RESULTS Our observations confirmed the increased risk in breast cancer with rs 2910164 polymorphism in three genetic models: allele contrast fixed genetic model, Recessive fixed genetic model and CC vs. GG genetic model (P value 0.0109, 0.0404 and 0.0019, respectively). CONCLUSION The rs2910164 polymorphism is associated with increased breast cancer risk. We suggest that more multicenter studies with larger samples investigate this matter to further clarify the association and verify our findings.

Abstract
Background:
The pH variation of the injury site is an important factor in the failure of styptic
and its structural damage. In this study, the behaviour of a gelatin-silica hybrid in severe bleeding was
evaluated under different pH values. On the other hand, the effect of the hybrid particle size, which is one
of the key physical properties of the hybrid, has been studied in rapid control of haemostasis.
</P><P>
Method: The hybrid haemostatic behaviour varied drastically by changing the particle size, so that the
hybrid containing SiO2 with the average particle size of about 1 micro-meter (Hyb Gel-MSiO2) demonstrated
very poor ability in platelet adhesion in neutral pH, about 24%. Also, the aPTT was not
shorter than the normal time, whereas reduction of the particle size beyond a certain limit (with nanometer
SiO2 for Hyb Gel-NSiO2) led to both increasing platelet adhesion to 32% and very considerable
reduction of aPTT.
</P><P>
Results: Alignment of all results showed that the particle size reduction improves the haemostatic
behaviour of the hybrid toward its best performance by controlling excessive bleeding. By changing
the pH for a certain particle size, structural integrity, and thereby the hybrid haemostatic behaviour
changed dramatically. Therefore, the nano-hybrid showed the most blood absorption (around 470%) in
natural pH and acceded to a coherent structure. The results demonstrated that in alkaline or acidic
environment, the hybrid haemostatic behaviour was limited. Based on the results of this study, it was
found that changes in the hybrid behaviour in acidic pH were much more drastic than in alkaline pH,
and also the hybrid with the optimum particle size (Hyb Gel-NSiO2) can maintain the structural integrity
with rapid haemostasis (<3 seconds).
</P><P>
Conclusion: Based on the objective that the pH at the injury site change to the alkaline side, the resulting
hybrid has an excellent ability to control excessive bleeding and can be proposed for further in
vivo studies as a novel styptic.</P>

Abstract
An algorithm based on mean squares successive difference test applied to near-infrared and principal component analysis scores was developed to monitor and determine the blending profile and to assess the end-point in the statistical stabile phase. Model formulations consisting of an active compound (acetylsalicylic acid), together with microcrystalline cellulose and two grades of calcium carbonate with dramatically different particle shapes, were prepared. The formulation comprising angular-shaped calcium carbonate reached blending end-point slower when compared with the formulation comprising equant-shaped calcium carbonate. Utilizing the ring shear test, this distinction in end-point could be related to the difference in flowability of the formulations. On the basis of the two model formulations, a design of experiments was conducted to characterize the blending process by studying the effect of CaCO3 grades and fill level of the bin on blending end-point.

Abstract
BACKGROUND Dentistry is a therapeutic health care profession that is related to people's health. Moreover medical emergencies often occur in dental offices that little awareness of the professional workers can have unpleasant consequences. MATERIALS AND METHODS In this interventional study, a survey of 45 final year dental students was examined. To do so, a test in terms of knowledge was taken as a standard questionnaire, and in the practical part a test was taken as on objective structured clinical examinations (OSCE) test in three stations, before and after the workshop; identification of emergency instruments, the performance of intramuscular and intravenous injections and cardiopulmonary resuscitations before and after the workshop obtained data were analyzed using, SPSS version 16, Student's t-test and paired T. RESULTS Using the t-test, mean score of the students' knowledge prior to and after the workshop were 51 ± 13.08 and 83.41 ± 8.65 respectively (P = 0.000). The practical score (OSCE) of dental students was 50.85 ± 13.09, which after the workshop came up to 85.73 ± 7.06 came up (P = 0.000). T-test of the performance before and after the workshop had a significant difference in each of the three stations. Significant differences between male and female students' knowledge and performance scores don't exist before and after the workshop (P > 0.05). CONCLUSION The level of knowledge and performance of students were assessed as average, therefore, training courses and revised the curriculum units are required.

Abstract
A high-voltage microfluidic controller designed using DALSA semiconductor's 0.8-mum low-voltage/high-voltage complementary metal-oxide semiconductor/double diffused metal-oxide semiconductor process is presented. The chip's four high-voltage output drivers can switch 300 V, and the dc-dc boost converter can generate up to 68 V using external passive components. This integrated circuit represents an advancement in microfluidic technology when used in conjunction with a charge coupling device (CCD)-based optical system and a glass microfluidic channel, enabling a portable and cost-efficient platform for genetic analysis.

Abstract
Electrophoresis is a mainstay of lab-on-a-chip (LOC) implementations of molecular biology procedures and is the basis of many medical diagnostics. High voltage (HV) power supplies are necessary in electrophoresis instruments and are a significant part of the overall system cost. This cost of instrumentation is a significant impediment to making LOC technologies more widely available. We believe one approach to overcoming this problem is to use microelectronic technology (complementary metal-oxide semiconductor, CMOS) to generate and control the HV. We present a CMOS-based chip (3 mm x 2.9 mm) that generates high voltages (hundreds of volts), switches HV outputs, and is powered by a 5 V input supply (total power of 28 mW) while being controlled using a standard computer serial interface. Microchip electrophoresis with laser induced fluorescence (LIF) detection is implemented using this HV CMOS chip. With the other advancements made in the LOC community (e.g. micro-fluidic and optical devices), these CMOS chips may ultimately enable 'true' LOC solutions where essentially all the microfluidics, photonics and electronics are on a single chip.

Abstract
Choosing the most suitable treatment for scoliosis relies heavily on accurate and reproducible Cobb angle measurement from successive radiographs. The objective is to reduce variability of Cobb angle measurement by reducing user intervention and bias. Custom software to automate Cobb angle measurement from posteroanterior radiographs was developed using active shape models. Validity and reliability of the automated system against a manual and semi-automated measurement method was conducted by two examiners each performing measurements on 3 occasions from a test set (N=22). A training set (N=47) of radiographs representative of curves seen in a scoliosis clinic was used to train the software to recognize vertebrae from T4 to L4. Images with a maximum Cobb angle between 20 degrees and 50 degrees, excluding surgical cases, were selected for training and test sets. Automated Cobb angles were calculated using best-fit slopes of the detected vertebrae endplates. Intra-class correlation coefficient (ICC) and standard error of measurement (SEM) showed high intra-examiner (ICC > 0.90, SEM 2-3 degrees) and inter-examiner (ICC > 0.82, SEM 2-4 degrees), but poor inter-method reliability (ICC=0.30, SEM 8-9 degrees). The automated method underestimated large curves. The reliability improved (ICC = 0.70, SEM 4-5 degrees) with exclusion of the 4 largest curves (>40 degrees) in the test set. The automated method was reliable for moderate sized curves, but did not properly detect vertebrae in larger curves. Optimization of constraints on scaling, rotation, translation, and iteration may improve reliability with larger curves.

Abstract
Walnut (Juglans regia L.) is described as an anticancer, tonic, blood purifier, and detoxifier agent. It is said that nuts have favorable fatty acids and nutrients. This study was performed to determine the lipid-lowering properties of walnut in a population in Shiraz, Southern Iran. In a randomized case-control study, 52 volunteers were divided into 2 groups: Group A consumed walnuts, 20 grams per day for 8 weeks and the control group (group B) consumed no walnuts. Triglycerides, total high-density lipoprotein (HDL), and low-density lipoprotein (LDL) levels were checked for each subject prior to, after 4 weeks, and at 8 weeks after the beginning of the study. In group A, the mean plasma TG level dropped by 17.1% from the baseline and HDL cholesterol also increased significantly by 9%. It was shown that frequent consumption of nuts in the daily diet was associated with a potentially decreased risk of coronary artery disease by decreasing the level of triglyceride and increasing the level of HDL.

Abstract
Cefuroxime and ampicillin were compared in a randomized double-blind trial in the treatment of severe lower respiratory tract infections. 750 mg of cefuroxime were given to 57 patients and 500 mg of ampicillin to 54 patients by intramuscular injection three times daily for 7-10 days. The patients had acute exacerbations of chronic bronchitis with or without pneumonia, a few had bronchiectasis and an underlying bronchial carcinoma was present in nearly a quarter. By the end of treatment the sputum, initially always mucopurulent, had become mucoid in 87.7% of patients receiving cefuroxime in comparison to 48.1% of those receiving ampicillin. A satisfactory clinical response was observed in 94.7 and 68.5%, respectively. Both these differences between cefuroxime and ampicillin are statistically significant (p less than 0.001).
