Many reproductive proteins from diverse taxa evolve rapidly and adaptively. These proteins are typically involved in late stages of reproduction such as sperm development and fertilization, and are more often functional in males than females. Surprisingly, many germline stem cell (GSC) regulatory genes, which are essential for the earliest stages of reproduction, also evolve adaptively in Droso...

background: cutaneous leishmaniasis constitutes a major public health problem in many parts of the world including iran. the primary objective of this study was to identify leishmania spe­cies in endemic districts of kerman province, south-eastern iran . methods: this study was conducted by random sampling as cross- sectional descriptive between 2008 and 2010. overall, 203 skin scraping smears ...

The early SV40 BstXI-BamHI (Bst/Bam) DNA fragment encodes exclusively for the second exon of the large T-antigen and contains the intact small t-antigen intron. Rat cells transformed by the p14T, a construct that carries the Bst/Bam DNA fragment as a tail-to-head tandem duplication, synthesize a truncated T-antigen (T1-antigen) without having a direct equivalent at the DNA level. Formation of t...

A simple method for attaching immunoglobulin G (IgG) on the cell surface was successfully developed for enhancing phagocytosis of apoptotic tumor cells (ATCs) by dendritic cells (DCs) ex vivo. By conjugating with a poly(ethylene glycol) (PEG)-lipid, named the biocompatible anchor for the membrane (BAM), arbitrary IgG could be incorporated into the cell membrane. In particular, when IgG-BAM conj...

Recently, strong interests in the real-time performance management are increasing to gain competitive advantages in the rapidly changing business environment. For better business performance or continuous process improvement of an enterprise, real-time measurement and analysis of the performance of managerial activities is essential. Business activity monitoring (BAM) which provides real-time a...

In the Drosophila ovary, germline stem cell (GSC) self-renewal is controlled by both extrinsic and intrinsic factors. The Bmp signal from niche cells controls GSC self-renewal by directly repressing a Bam-dependent differentiation pathway in GSCs. pelota (pelo), which has been previously shown to be required for Drosophila male meiosis, was identified in our genetic screen as a dominant suppres...

Stem cells execute self-renewing and asymmetric cell divisions in close association with stromal cells that form a niche. The mechanisms that link stromal cell signaling to self-renewal and asymmetry are only beginning to be identified, but Drosophila oogenic germline stem cells (GSCs) have emerged as an important model for studying stem cell niches. A member of the Bone Morphogenetic Protein (...

PURPOSE Balloon-assisted maturation (BAM) is emerging as a salvage management for arteriovenous fistula maturation failure (AVF MF). However, BAM is a relatively new, yet controversial technique for AVF maturation. Therefore, we evaluated the effectiveness of BAM for AVF MF. METHODS Between January 2012 and December 2014, 249 AVFs were created. The total MF rate was 24.8%. But, only 110 AVFs ...

UNLABELLED In Gram-negative bacteria, the Lol and Bam machineries direct the targeting of lipidated and nonlipidated proteins, respectively, to the outer membrane (OM). Using Pseudomonas aeruginosa strains with depleted levels of specific Bam and Lol proteins, we demonstrated a variable dependence of different OM proteins on these targeting pathways. Reduction in the level of BamA significantly...
