We describe the partial purification and characterization of a pore-forming material (PEM) from Entamoeba histolytica. The formation of ion channels by PFM was examined in three systems. (a) PFM depolarizes J774 macrophages and mouse spleen lymphocytes as measured by [3H]TPP+ uptake. (b) PFM induces rapid monovalent cation flux across the membrane of phosphatidylcholine-cholesterol vesicles. (c...

The objective of this study was to evaluate the relationship between aerobic capacity and pelvic floor muscles (PFM) function in adult women. Women aged 18 or over and without urinary dysfunction or other chronic diseases were eligible to participate. They completed the habitual physical activity (HPA) questionnaire, underwent a PFM functional evaluation by palpation and perineometry, and perfo...

The Pseudomonas aeruginosa quorum sensing (QS) system is controlled by the signal molecules acyl homoserine lactones (AHLs) that are synthesized from acyl enoyl-acyl carrier proteins (acyl-ACPs) provided by the fatty acid biosynthesis cycle. Pfm (PA2950), an enoyl-CoA reductase, has previously been shown to affect swimming mobility and fatty acid biosynthesis. In this report, we further show th...

INTRODUCTION It has been suggested that pelvic floor muscles (PFMs) play an important role in provoked vestibulodynia (PVD) pathophysiology. Controversy in determining their exact contribution may be explained by methodological limitations related to the PFM assessment tools, specifically the pain elicited by the measurement itself, which may trigger a PFM reaction and introduce a strong bias. ...

background: sickle cell disease (hbss) is a major health problem in nigeria and ma-laria has been implicated as a leading cause of morbidity/mortality in sickle cell disease patients. few reasons were put forward to explain the observed morbidity/mortality of hbss subjects due to plasmodium falciparum (p. falciparum) malaria. objectives: to determine the level of immunoglobulin classes (igm, ig...

The ability to detect single trial responses in functional magnetic resonance imaging (fMRI) studies is essential, particularly if investigating learning or adaptation processes or unpredictable events. We recently introduced paradigm free mapping (PFM), an analysis method that detects single trial blood oxygenation level dependent (BOLD) responses without specifying prior information on the ti...

INTRODUCTION AND OBJECTIVES several studies have been investigated co-activation can enhance the effectveness of PFM training protocols allowing preventive and therapeutic goals in pelvic floor dysfunctions. The objective of the present study was to investigate if an abdominal-pelvic protocol of training (APT) using gametherapy would allow co-activation of PFM and transversus abdominis/oblique ...

[Purpose] The aim of the present study was to examine the impact of the pelvic floor muscles (PFM) on dynamic ventilation maneuvers. [Subjects and Methods] The subjects were 19 healthy female adults in their 20s who consented to participate in the present study. Electromyography (EMG) was used to examine respiratory muscle activity, and a spirometer was used to examine vital capacity before and...

Objective: To perform a clinical trial to evaluate human embryos generated in the protein-free medium (PFM). Materials and methods: The quality of embryos generated in medium with (control; Medi-Cult) and without protein (test; ART-7b) and their viability were compared. Sperm was prepared in control or test media as appropriate. Effect of different antibiotic supplements in the PFM was investig...
