Filamentous hemagglutinin (FHA), the major 230-kDa adhesin of the whooping cough agent Bordetella pertussis, is one of the most efficiently secreted proteins in Gram-negative bacteria. FHA is secreted by means of the two-partner secretion (TPS) pathway. Several important human, animal, and plant pathogens also secrete adhesins and other virulence factors by using this mode of secretion. A TPS s...

Introduction: The effect of esophageal distension (ED) on gastric motility has been well documented, but a few investigations have been carried out on the effect of ED on gastric secretion. The aim of this study was to investigate the effect of ED on gastric acid and pepsin secretion and the mechanism(s) involved. Methods: Male adult Wistar rats (200-240 g) were anesthetized with urethane (1...

UNLABELLED Mycobacterium tuberculosis is a leading cause of death worldwide. The M. tuberculosis TAT (twin-arginine translocation) protein secretion system is present at the cytoplasmic membrane of mycobacteria and is known to transport folded proteins. The TAT secretion system is reported to be essential for many important bacterial processes that include cell wall biosynthesis. The M. tubercu...

Intimate partner violence (IPV) is a significant public health problem in South Africa. However, there is limited research on whether and how IPV changes during pregnancy and the postpartum period and on the factors that might affect women's risk during this time. In this study, we describe the mean trajectories of physical and psychological IPV during pregnancy and the postpartum period and ex...

The moderating effect of partner empathy on the relationship between both directions of work-family conflict (work-to-family and family-to-work) and psychological distress of both the job incumbent and partner are examined in this study. Considering empathy as a specific dimension of emotional social support, we hypothesized that receiving empathy would buffer negative spillover to the job incu...

Background: Multidrug resistance Pseudomonas aeruginosa (MDRPA) is most important issue in healthcare setting. It can secrete many virulence effector proteins via its secretion system type (T1SS-T6SS). They are using them as conductor for delivering the effector proteins outside to begins harmful effect on host cell increasing pathogenicity, competition against other microorganism and nutrient ...
