作者： Awad Elsid Osman Sahar Alharbi atif Ali Ahmed Asim Ali Elbagir Pathology and Clinical Laboratory Management Department(PCLM) King Fahad Medical CityRiyadhSaudi Arabia Department of Pathology and Laboratory Medicine University of Missouri at Children's Mercy HospitalKansas CityMOUSA

Objective: Genome-wide association studies have demonstrated that single nucleotide polymorphisms (SNPs) are important risk factors for the development of prostate cancer (PCa). Preliminary studies have suggested that the incidence of PCa in Saudi males is low but is probably familial or genetically ***: To identify any possible association of SNP with PCa development in Saudi patients, we investigated a group of SNPs in Saudi PCa patients (n=85) and compared the outcomes to healthy normal controls (n=115) and nodular hyperplasia patients (n=120). DNA was extracted from paraffin-embedded formalin fixed tissue or whole blood from both patients’ groups and healthy control group. A total of thirteen SNPs were genotyped using TaqMan® minor groove binder polymerase chain reaction ***: The rs16901979A, s629242T and rs1447295A alleles were found at significantly higher frequency in PCa patients than controls (p< 0.05). The rs16901979 CA genotype was found at significantly greater frequency in PCa patients than in healthy controls (43% vs. 14%, odds ratio=4.6, p=0.0001) and benign hyperplasia group (43% vs. 25%, odds ratio=2.2, p=0.009).Conclusion: Our study has highlighted the association of rs16901979 SNP with PCa in Saudi males. Such findings have important implications in the PCa diagnosis and in screening unaffected family members of Saudi patients.

DNBP-CCA:A Novel Approach to Enhancing Heterogeneous Data Traffic and Reliable Data Transmission for Body Area Network

The increased adoption of Internet of Medical Things (IoMT) technologies has resulted in the widespread use ofBody Area Networks (BANs) in medical and non-medical domains. However, the performance of IEEE 802.15.4-based BANs is impacted by challenges related to heterogeneous data traffic requirements among nodes, includingcontention during finite backoff periods, association delays, and traffic channel access through clear channelassessment (CCA) algorithms. These challenges lead to increased packet collisions, queuing delays, retransmissions,and the neglect of critical traffic, thereby hindering performance indicators such as throughput, packet deliveryratio, packet drop rate, and packet delay. Therefore, we propose Dynamic Next Backoff Period and Clear ChannelAssessment (DNBP-CCA) schemes to address these issues. The DNBP-CCA schemes leverage a combination ofthe Dynamic Next Backoff Period (DNBP) scheme and the Dynamic Next Clear Channel Assessment (DNCCA)scheme. The DNBP scheme employs a fuzzy Takagi, Sugeno, and Kang (TSK) model’s inference system toquantitatively analyze backoff exponent, channel clearance, collision ratio, and data rate as input parameters. Onthe other hand, the DNCCA scheme dynamically adapts the CCA process based on requested data transmission tothe coordinator, considering input parameters such as buffer status ratio and acknowledgement ratio. As a result,simulations demonstrate that our proposed schemes are better than some existing representative approaches andenhance data transmission, reduce node collisions, improve average throughput, and packet delivery ratio, anddecrease average packet drop rate and packet delay.

具有除菌性能的电容去离子材料对于制备高效节能同时具备脱盐和抗微生物污染功能的电极材料至关重要,然而由于双电层电吸附机制的影响,多数碳基材料的吸附容量受到限制.同时,近年来部分研究学者通过对电极材料进行抗菌化合物的修饰并用于电容法水除菌已得到证明.因此为了实现高效、低成本的同时实现电容脱盐和除菌,本研究提出了一种简便的方法制备氧化石墨烯/聚苯胺/普鲁士蓝纳米复合材料作为类法拉第电极用于电容去离子和水消毒应用.所合成的电极材料具有较高的BET表面积(148.08m^(2)g^(-1))、介孔体积(34.02cm^(3)g^(-1))和孔体积(0.66cm^(3)g^(-1)),在1Ag^(-1)下的脱盐容量为91.6mgg^(-1),脱盐率为3.05mgg^(-1)min^(-1).此外,在未添加额外消毒剂的情况下,该复合材料所制备的电极能有效去除和灭活94.0%±3.1%的大肠杆菌,其杀菌效率是活性炭电极的7倍.本研究对未来将普鲁士蓝基复合材料的法拉第电极用于高效环保海水淡化和消毒材料的应用奠定了研究基础.
