Chitin is mainly formed by the chitin synthase III complex (CSIII) in yeast cells. This complex is considered to be composed of the catalytic subunit Chs3 and the regulatory subunit Chs4, both of which are phosphoproteins and transported to the plasma membrane by different trafficking routes. During cytokinesis, Chs3 associates with Chs4 and other proteins at the septin ring, which results in an active CSIII complex. In this study, we focused on the role of Chs4 as a regulatory subunit of the CSIII complex...

The mycobacterial cell envelope is a complex multilayered structure that provides the strength to the rod-shaped cell and creates the permeability barrier against antibiotics and host immune attack. In this review, we will discuss the spatial coordination of cell envelope biosynthesis and how plasma membrane compartmentalization plays a role in this process. The spatial organization of cell envelope biosynthetic enzymes as well as other membrane-associated proteins is crucial for cellular processes such as polar growth and midcell septum formation...

PURPOSE: Whether pathologic alterations of right ventricle (RV) in chronic obstructive pulmonary disease (COPD) affect intra- and interventricular dyssynchrony due to changes in mechanical activation of the septum and RV is unclear. The aim of this study was to determine mechanical activation and its changes after pulmonary rehabilitation program (PRP) with speckle tracking echocardiography (STE) in COPD patients. METHODS: After the exclusion of 15 patients due to poor echogenicity and 5 patients not tolerating PRP out of 69 consecutive COPD patients undergoing PRP, the remaining 49 patients and 41 healthy subjects were enrolled...

Different types of ependymal areas were studied and labelled in the human brain lateral ventricle. Periventricular structures were included in coining the names of the ependymal areas because they represent a basic and stable part of brain nerve structures suitable for the sake of clarity of localization of the ependyma. The labelling of individual ependymal areas was composed from letters: "Lv" (lateral ventricle); "E" (ependymal area) and letters for abbreviations of the closest periventricular structure, e...

Understanding the neurobiology of social bonding in non-human primates is a critical step in understanding the evolution of monogamy, as well as understanding the neural substrates for emotion and behavior. Coppery titi monkeys ( Callicebus cupreus ) form strong pair bonds, characterized by selective preference for their pair mate, mate-guarding, physiological and behavioral agitation upon separation, and social buffering. Mate-guarding, or the "maintenance" phase of pair bonding, is relatively under-studied in primates...

Although the hypothalamus is classified into more than 10 compartments, it still contains uncharacterized areas. In this study, we identified a new triangular-shaped area between the paraventricular hypothalamic nucleus (PVN) and the fornix area in the mouse anterior hypothalamus, which is enriched in chondroitin sulfate proteoglycans (CSPGs). We designated this region as the perifornical area of the anterior hypothalamus (PeFAH) based on its anatomical location. As evidenced by Nissl staining, the PeFAH was distinguishable as an area of relatively low density...

Early life stress (ELS) shapes the way individuals cope with future situations. Animals use cognitive flexibility to cope with their ever-changing environment and this is mainly processed in forebrain areas. We investigated the performance of juvenile gilthead seabream, previously subjected to an ELS regime. ELS fish showed overall higher brain catecholaminergic (CA) signalling and lower brain derived neurotrophic factor (bdnf) and higher cfos expression in region-specific areas. All fish showed a normal cortisol and serotonergic response to acute stress...

The hormone ghrelin promotes eating and is widely considered to be a hunger signal. Ghrelin receptors, growth hormone secretagogue receptors (GHSRs), are found in a number of specific regions throughout the brain, including the lateral septum (LS), an area not traditionally associated with the control of feeding. Here we investigated whether GHSRs in the LS play a role in the control of food intake. We examined the feeding effects of ghrelin and the GHSR antagonists ([D-Lys3]-GHRP-6 and JMV 2959), at doses subthreshold for effect when delivered to the lateral ventricle...

BACKGROUND: A-V-sequential pacing has been shown to induce reversible conduction delay and subsequent asymmetric remodelling of the left ventricle (LV) in dogs and pigs. Both species have disadvantages in animal experiments. Therefore aim of this study focusses at developing a more feasible and easy-to-use animal model in sheep. METHODS: Dual-chamber pacing (DDD) pacemakers (right atrium + right ventricular free wall) were surgically implanted in 13 sheep. All animals underwent 8 weeks of chronic rapid pacing at 180 bpm...
