Erythrocytes from patients with chronic hemolytic variants of glucose-6-phosphate dehydrogenase (G-6-PD) deficiency have structural membrane protein abnormalities accompanied by decreased cell membrane deformability which we postulate represent the consequences of oxidant-induced membrane injury. To evaluate the pathophysiologic significance of oxidant-induced membrane injury, we studied the in...

PURPOSE We investigated if programmed death-ligand 1 (PD-L1) expression levels were prognostic of survival outcomes after intensity-modulated radiation therapy (IMRT) for non-metastatic nasopharyngeal carcinoma (NPC). METHODS AND MATERIALS 104 patients with non-metastatic NPC treated with radical IMRT were investigated for their PD-L1 expression by immunohistochemistry (IHC) which were correl...

This review paper describes new data on the role of aquaporins in peritoneal function, peritoneal membrane permeability, peritoneal dialysis (PD) adequacy and peritoneal membrane histology, new aspects of the use of PD solutions alternative to glucose ones and indications for use of peritoneal catheters with different configurations. Results of main studies, published predominantly in 2003-2004...

Glucagon inhibits gastric acid secretion and increases the negativity of gastric mucosal potential difference (PD) in man. To test the hypothesis that the increased negativity of PD after glucagon in man could be due to decreased parietal cell canalicular membrane area, a quantitative ultrastructural analysis was carried out. Four healthy volunteers with normal gastric mucosa were submitted to ...

BACKGROUND It has been demonstrated that platycodin D (PD) exhibits anti-cancer activities. This study aims to investigate the anti-proliferative effects of the combination of PD and doxorubicin (DOX) on human breast cancer cells (MCF-7 and MDA-MB-231 cells). METHODS The anti-proliferative effects of different dosages of PD, DOX, and PD + DOX on MCF-7 and MDA-MB-231 cells were determined by t...

In fifty-seven resting nerve fibers of the squid Sepioteuthis sepioidea impaled from outside to inside, three potential difference (PD) levels were recorded. In twelve nerve fibers the position of the tip of the micropipette, when it was recording one of the PD levels, was labeled with carmine, and the minute spot of dye was localized histologically. The first PD level of -10 to -26 mv, was loc...

Pathogenic microorganisms deliver protein effectors into host cells to suppress immune responses. Recent findings reveal that phytopathogens manipulate the function of plant cell-to-cell communication channels known as plasmodesmata (PD) promote diseases. Several bacterial and filamentous pathogen have been shown regulate PD in their cells. A few pathogens reported move from infected neighborin...

BACKGROUND Pompe disease (PD) is a metabolic myopathy caused by alpha-glucosidase (GAA) deficiency and characterized by generalized glycogen storage. Heterogeneous GAA gene mutations result in wide phenotypic variability, ranging from the severe classic infantile presentation to the milder intermediate and late-onset forms. Enzyme replacement therapy (ERT) with recombinant human GAA (rhGAA), th...

Abstract Parkinson’s disease (PD) is the second-most common neurodegenerative worldwide. Several studies have investigated PD for decades; however, exact mechanism of development remains unknown. To study PD, SH-SY5Y cells are often treated with 6-hydroxydopamine (6-OHDA) or 1-methyl-4-phenylpyridinium (MPP+) to induce PD. understand pathogenesis, we confirmed protein changes between 6-OHDA- an...

after alzheimer disease, parkinson disease (pd) is considered the most common neurodegenerative disease. its prevalence is the same in all area but it is common in males than females. from every 100 persons who are above 60 years old, one of them has pd. also 5-10% of patients are less than 40 years old. this progressive neuroinflammation disease isn’t fatal. in 60% of cases is with depression....
