PURPOSE Microaneurysms (MAs) are considered a hallmark of retinal vascular disease, yet what little is known about them is mostly based upon histology, not clinical observation. Here, we use the recently developed adaptive optics scanning light ophthalmoscope (AOSLO) fluorescein angiography (FA) to image human MAs in vivo and to expand on previously described MA morphologic classification schem...
The angiotensin type 2 receptor (AT2R) and the receptor MAS are receptors of the protective arm of the renin-angiotensin system. They mediate strikingly similar actions. Moreover, in various studies, AT2R antagonists blocked the effects of MAS agonists and vice versa. Such cross-inhibition may indicate heterodimerization of these receptors. Therefore, this study investigated the molecular and f...
BACKGROUND Follicular fluid meiosis-activating sterol (FF-MAS) overcomes hypoxanthine (HX)-mediated meiotic arrest in mammalian oocytes. METHODS In order to determine whether chromosome segregation was normal in oocytes matured in FF-MAS, the development, chromosomal constitution and chromosome alignment was analysed in spontaneously matured as well as HX-arrested mouse oocytes cultured in th...
There is a growing demand for Multi-Agent Systems (MAS) in the software industry. The autonomous agent interaction in a dynamic software environment can potentially lead to runtime behavioral failures including deadlock. In order to bring MAS to the main stream of commercial software development, the behavior of MAS must be tested and monitored against the risk of unwanted emergent behaviors in...
Macrophage activation syndrome (MAS), also known as secondary hemophagocytic lymphohistiocytosis, is mediated by cytokine overproduction from excessive activation of T lymphocytes and macrophages. We present a dermatomyositis patient with MAS, caused by hypercytokinemia. The combination of tacrolimus and plasma exchange therapy was effective in this case for treating MAS. This combination thera...
Our aim was to investigate the effect of the level of stringency of quantitative trait loci (QTL) detection in a genome scan on the accuracy of subsequent maker assisted selection (MAS). A genome scan and subsequent MAS were performed in a population of simulated pigs. The accuracy of MAS was greatest when QTL with P < 0.10 (on an individual gene basis) in the genome scan were used in MAS. More...
the classical triad of mccune-albright syndrome (mas) consists of polyostotic fibrous dysplasia (fd), skin hyperpigmentation (café-au-lait spots), and endocrine dysfunction, frequently seen in females as precocious puberty. etiology is genetically based and is explained by mosaicism of activating somatic mutations of the alpha-subunit of gs protein. clinical presentation is varied and is depend...
The morphology of the isolated sea-urchin mitotic apparatus (MA) was examined by light and electron microscopy. With the polarization microscope and the Nomarski differential interference microscope, the isolated MAs appeared to be similar to in vivo MAs. Electron microscopy of the isolated MAs revealed the presence of microtubules, ribosome-like particles and vesicles. A close association betw...
Retinal microaneurysms (MAs) are the earliest clinically observable lesions of diabetic retinopathy. Reliable automated MAs detection is thus critical for early diagnosis of diabetic retinopathy. This paper proposes a novel method for the automated MAs detection in color fundus images based on gradient vector analysis and class imbalance classification, which is composed of two stages, i.e. can...
