Background: The PIWI-interacting RNA (piRNA) pathway has an essential role in transposon silencing, meiosis progression, spermatogenesis, and germline maintenance. HIWI genes are critical for piRNA biogenesis and function. Therefore, polymorphisms in HIWI genes contribute to spermatogenesis defects and can be considered as risk factors for male infertility. The aim of the present study was to i...

We consider a fully decentralized multi-player stochastic multi-armed bandit setting where the players cannot communicate with each other and can observe only their own actions rewards. The environment may appear differently to different players, i.e., reward distributions for given arm are heterogeneous across players. In case of collision (when more than one player plays same arm), we allow c...

BACKGROUND In the current study we aimed to find out the impact of cytokine-inducible Src homology 2 domain protein (CISH) gene polymorphisms on the risk of pulmonary tuberculosis (PTB) in a sample of Iranian population. MATERIALS AND METHODS Polymorphisms of CISH rs2239751, rs414171, and rs6768300 were determined in 200 PTB patients and 200 healthy subjects using T-ARMS-PCR or PCR-RFLP metho...

AIMS An abnormality in the glycated haemoglobin peak (Hb A1c) on Diastat (Bio-Rad) cation exchange low pressure liquid chromatography (LPLC) was found in three Punjabi patients with diabetes. The aims of this study were to identify the variant by chromatography and electrophoresis and to determine whether a DNA analysis test could be designed for confirmation that could be generally applied for...

BACKGROUND A significant role of Renin-angiotensin system (RAS) genetic variants in the pathogenesis of essential hypertension and cardiovascular diseases has been proved. This study aimed to develop a new, fast and cheap method for the simultaneous detection of two missense single nucleotide polymorphisms (T207M or rs4762 and M268T orrs699) of angiotensinogen (AGT) in single-step Multiplex Hex...

BACKGROUND Wilson disease is a rare disorder of copper metabolism due to mutation in ATP7B gene. Proper counseling of patients with Wilson disease, and their families necessitates finding mutation in ATP7B gene. Finding mutations in ATP7B gene with 21 exons, and more than 500 mutations is expensive and time-consuming. OBJECTIVES The aim of this study was to provide a simple multiplex amplific...

BACKGROUND Structural brain abnormalities have been described in individuals with an at-risk mental state for psychosis. However, the neuroanatomical underpinnings of the early and late at-risk mental state relative to clinical outcome remain unclear. AIMS To investigate grey matter volume abnormalities in participants in a putatively early or late at-risk mental state relative to their prosp...

BACKGROUND A beta-hemoglobin variant (beta 126 (H4) Val-->Gly) was reported from Thailand and Naples (Southern Italy) as Hb Dhonburi (1) and Hb Neapolis (2), respectively. This abnormal hemoglobin, resulting from a valine to glycine substitution in the contact region between alpha and beta subunits, gives rise to instability at non-physiological conditions. However, it was difficult to distingu...

BackgroundIt has been confirmed that the connective tissue growth factor (CTGF) gene rs9402373 polymorphism is associated with fibrotic and inflammatory diseases. However, studies on relationship between polymorphisms in CTGF bowel disease (IBD) remain rare. Therefore, aim of this study was to assess association IBD susceptibility a Chinese population.Materials methodsTo establish an amplificat...
