Microcystin-leucine arginine (MC-LR) is a harmful cyanotoxin produced by cyanobacteria. MC-LR can exert endocrine-disrupting activities in many organisms. We have previously demonstrated that MC-LR exerts both acute and chronic reproductive toxicity in male mice, resulting in a decline in sperm quality and damage to testicular structure. Moreover, we also observed extensive alterations in a pan...
■ Evidence summary Since natural menopause is clinically defined as the final menstrual period, the best way to diagnose it is to retrospectively observe 12 consecutive months of amenorrhea. Several studies followed women longitudinally and found the characteristics that best predicted actual transition to menopause within 4 years were amenorrhea of between 3 and 12 months duration (sensitivity...
در این مطالعه، سازوکار کانونی برای چهار زمین لرزه رخ داده در آذرماه 1392 در گستره کرمانشاه با بزرگی 5/4< mw، از طریق برگردان خطی تانسور گشتاور در حوزه زمان و با استفاده از الگوریتم ایزولا به دست آمده است. در این الگوریتم، روش واهمامیخت تکراری برای تمام شکل موج به کار گرفته شده و تابع گرین با روش عدد موج ناپیوسته محاسبه می شود. برگردان تانسور گشتاور برای این چهار زمین لرزه، لغزش معکوس با کمی مؤل...
علیرغم معرفی و بکارگیری روشهای متعدد بهنگام سازی ماتریس ضرایب مستقیم داده- ستانده در شش دهه گذشته، هنوز نکاتی از روشهای ras و ras تعدیل شده وجود دارند که در سالهای اخیر توجه تحلیلگران اقتصاد داده- ستانده را به خود معطوف کرده است. یکی از این نکات چالش برانگیز رابطه بین اطلاعات برونزا، برتر و یا اضافی بیشتر سال مقصد در روش ras تعدیل شده و کاهش خطاهای آماری آن نسبت به ras متعارف در بهنگام سازی ضرا...
This study examined the role of acid sphingomyelinase (ASM) and its redox amplification in mediating the formation of lipid raft (LR) redox signaling platforms in coronary arterial endothelial cells (CAECs). Using small interference RNA (siRNA) of ASM, Fas ligand (FasL)-induced increase in ASM activity, production of ceramide, and LR clustering in CAECs were blocked, and clustered Fas was also ...
BACKGROUND The relationship between surgical margin and local recurrence (LR) in osteosarcoma patients with poor responses to chemotherapy is unclear. Moreover, the incidences of LR according to three different resection planes (bone, soft tissue, and perineurovascular) are not commonly known. METHODS We evaluated the incidence of LR in three areas. To assess whether there is a role of surgic...
Lactobacillus reuteri 6475 (Lr) of the human microbiome synthesizes histamine and can suppress inflammation via type 2 histamine receptor (H2R) activation in the mammalian intestine. Gut microbes such as Lr promote H2R signaling and may suppress H1R proinflammatory signaling pathways in parallel by unknown mechanisms. In this study, we identified a soluble bacterial enzyme known as diacylglycer...
The aim of this study was to investigate whether the limbus-insertion distance (LID) of the lateral rectus (LR) muscle can be a useful indicator for predicting the surgical effect of recession surgery in intermittent exotropia (IXT). Patients who underwent unilateral or bilateral LR recession for the basic type of IXT were included. The distance between the corneal limbus and the posterior edge...
In recent years, microRNAs (miRNAs) in toxicology have attracted great attention. However, the underlying mechanism of miRNAs in the cytotoxicity of microcystin-LR (MC-LR) is lacking. The objective of this study is to analyze miRNA profiling in HepG2 cells after 24 h of MC-LR-exposure to affirm whether and how miRNAs were involved in the cytotoxicity of MC-LR. The results showed that totally 21...
