Nitric oxide synthase 2 gene polymorphisms are associated with prostatic volume in Korean men with benign prostatic hyperplasia

引用

Asian Journal of Andrology 2010年第5期12卷 690-696页

作者： koo han yoo Su Kang Kim Joo-Ho Chung Sung-Goo Chang Department of Urology School of Medicine Kyung Hee University Seou1130-702 Korea Kohwang Medical Research Institute School of Medicine Kyung Hee University Seoul 130-702 Korea

The precise aetiology of benign prostatic hyperplasia （BPH） remains unclear; however, it is known that immunological inflammatory processes have a role in the pathogenesis of BPH initiation and progression. Nitric oxide synthase 2 （NOS2） inducible expression is closely correlated with prostatic disease, including prostate cancer and BPH. The aim of this study was to investigate the relationship between NOS2 polymorphisms and BPH. With a cohort of 205 controls and 229 BPH subjects, we genotyped three single nucleotide polymorphisms （SNPs） in the NOS2 gene, including rs2779248 （promoter, -278 T/C）, rs 10459953 （5＇-untranslated region） and rs2297518 （exon 16, missense, Ser608Leu）, using direct sequencing and restriction fragment length polymorphism. The genotypic and allelic frequencies between control and BPH subjects were compared, and the associations among the BPH subjects were analyzed. SNPStats, SNPAnalyzer and HelixTree programmes were used to analyze SNPs. There was no association on SNPs between control and BPH subjects. When BPH subjects were analyzed, there was no association on SNPs between the low and high prostate-specific antigen groups. However, one SNP （rs 10459953, odds ratio [OR] = 0.44, 95% confidence interval [CI] = 0.29-0.65, P 〈 0.0001, in codominant model; OR = 0.23, 95% CI = 0.12-0.46, P 〈 0.0001, in dominant model; and OR = 0.46, 95% CI = 0.24-0.86, P = 0.015, in recessive model） was associated with prostatic volume in BPH. We detected a strong association in genotype frequencies of NOS2 SNP （rs10459953） between subjects with small and large prostatic volume in BPH. The result suggests that NOS2 may be associated with prostatic volume in BPH.

作者： Taesoo Choi koo han yoo Ran Song Dong-Gi Lee Department of Urology School of MedicineKyung Hee University Division of Rheumatology Department of Internal MedicineSchool of MedicineKyung Hee University

BACKGROUND Crossed fused renal ectopia is a rare congenital anomaly of the ascent of the kidney. This anomaly may be observed as a solitary kidney during initial evaluation. A solitary kidney must be evaluated for associated anomalies such as duplication,horseshoe kidney,or crossed renal *** SUMMARY An anomaly was observed in a 9-mo-old male child who was subsequently diagnosed with crossed fused renal ectopia and vesicoureteral reflux(VUR). In this condition,recurrent febrile urinary tract infection can be a serious problem,and can easily cause renal damage due to relatively short ureters and high pressure in the *** To prevent urosepsis and preserve renal function,early diagnosis and proper management including surgical correction should be considered for the management of renal ectopia with VUR.

Soft electromechanical sensors have led to a new paradigm of electronic devices for novel motion-based wearable applications in our daily lives. However, the vast amount of random and unidentified signals generated by complex body motions has hindered the precise recognition and practical application of this technology. Recent advancements in artificial-intelligence technology have enabled significant strides in extracting features from massive and intricate data sets, thereby presenting a breakthrough in utilizing wearable sensors for practical applications. Beyond traditional machine-learning techniques for classifying simple gestures, advanced machine-learning algorithms have been developed to handle more complex and nuanced motion-based tasks with restricted training data sets. Machine-learning techniques have improved the ability to perceive, and thus machine-learned wearable soft sensors have enabled accurate and rapid human-gesture recognition, providing real-time feedback to users. This forms a crucial component of future wearable electronics, contributing to a robust human–machine interface. In this review, we provide a comprehensive summary covering materials, structures and machine-learning algorithms for hand-gesture recognition and possible practical applications through machine-learned wearable electromechanical sensors.
