Objective: To propose a new typing method for sylvian arachnoid cysts (SACs) and to provide a basis for the choice of surgical approaches of SACs. Methods: 34 cases of SACs were divided into 3 types: I type. SACs medial cyst wall was located in the outer 1/3 of sylvian fissure; type II. SACs medial cyst wall was located in median 1/3 of sylvian fissure; III type. Type I and Type II accepted neu...

Dendritic and axonal arbors of many neuronal types exhibit self-avoidance, in which branches repel each other. In some cases, these neurites interact with those of neighboring neurons, a phenomenon called self/non-self discrimination. The functional roles of these processes remain unknown. In this study, we used retinal starburst amacrine cells (SACs), critical components of a direction-selecti...

An accurate description of the number, location and relative position of the air sacs and their diverticula in the ostrich is essential for a better understanding of the pathogenesis of air sacculitis in this bird. The air sacs were studied in ten ostriches of varying ages by latex or silicone casting of the respiratory tract and dissection. Results revealed that the air sacs of the ostrich con...

Tumours of the perianal region occur frequently in dogs (Bennett et al. 2002), with benign adenomas comprising 5896% of tumours at this site (Turek & Withrow 2013). In some cases these may transform to become malignant perianal adenocarcinomas, and these need to be distinguished from adenocarcinomas which derive from the apocrine secretory epithelium within the wall of the anal sacs (Polton & B...

Cytoplasmic polyadenylation element binding protein 3 (CPEB3) regulates target RNA translation in neurons. Here, we examined CPEB3 distribution and function in the mouse retina. CPEB3 is expressed in retinal neurons, including those located in the inner nuclear layer (INL) and ganglion cell layer (GCL) but not in cone and rod photoreceptors in the outer nuclear layer (ONL). A previous study fou...

OBJECTIVE To investigate the prevalence of detectable jugular lymphatic sacs in a setting for first trimester screening for Down syndrome, and to evaluate the influence of jugular lymphatic sacs on the screening performance for chromosomal abnormalities. METHODS A prospective single center study (Erasmus University Medical Center, Rotterdam, The Netherlands) over a period of one year (January...

The long-unresolved issue of CO2 release and the resulting atmospheric change can be solved through application effective catalysts. Thus, single-atom catalysts (SACs) have been rapidly developed for reduction reaction (CO2RR), as they show improved catalytic metrics enable generation C2+ products. Among numerous novel SACs, such those based on graphene, metal–organic frameworks, covalent organ...

Many microorganisms synthesize a wide range of surface active compounds (SACs), classified according to their molecular weights, properties and localizations. The low molecular weight SACs or biosurfactants lower the surface tension at the air/water interfaces and the interfacial tension at oil/water interfaces, whereas the high molecular weight SACs, also known as bioemulsifiers, are more effe...

The purpose of this article was to evaluate the accuracy of predicting amnionicity using the number of yolk sacs by diagnostic ultrasound examination in monochorionic (MC) multifetal pregnancies between 7 + 0 and 9 + 6 gestational weeks. A total of 97 patients with MC multifetal pregnancies underwent early ultrasound examination from 2004 to 2014 at Cheil General Hospital and Women's Healthcare...
