Human pluripotent stem (hPS) cells, mainly represented by human embryonic stem (hES) and human induced pluripotent stem (hiPS) cells, are considered as a virtually unlimited material for biomedical research and cell-based therapies. However, their use in the clinics requires efficient and bio-safe handling. Cryopreservation is an obligate key step of storage and transportation, during which the...
Physical stimuli can act in either a synergistic or antagonistic manner to regulate cell fate decisions, but it is less clear whether insoluble signals alone can direct human pluripotent stem (hPS) cell differentiation into specialized cell types. We previously reported that stiff materials promote nuclear localization of the Yes-associated protein (YAP) transcriptional coactivator and support ...
Two types of gap phenomena (types I and II ) have been described in human hearts and their electrophysiologic bases have been delineated. In both types of gap phenomena relatively early premature atrial impulses are blocked within some portion of the His-Purkinje system (HPS). By increasing the prematurity of the atrial depolarization, conduction to the ventricles resumes due to delay of the pr...
BACKGROUND Hantavirus pulmonary syndrome (HPS) is an emerging rodent-borne disease in the American continent, characterized by acute respiratory distress and a high case-fatality ratio. The present work describes a case of HPS, with favorable outcome, whose initial features were mistaken for leptospirosis or other less severe acute infections. METHODOLOGY The case of a 32-year-old male with a...
To study the effects of post-stripping oocyte ageing at low temperatures on the viability of kutum (Rutilus kutum) oocytes, unfertilised eggs of five females were stored in ovarian fluid at temperatures of 4 and 7 degree centigrade for 24 hours post stripping (HPS). The stored ova of five female kutum were separately fertilised at 0 (i.e., control eggs fertilised prior to storage), 4, 8, 12, 16...
Introduction : which is manifested by reduction in arterial blood oxygen. The present study was conducted to evaluate the frequency, clinical and para clinical features of HPS, and to determine their predictive values in diagnosis in a group of Iranian patients . Materials and methods : consecutively to the gastroenterology department of Taleghani Hospital between 2003 and 2004. Patients unde...
background : hepatopulmonary syndrome (hps) refers to arterial hypoxemia caused by pulmonary vasodilation, which is a consequence of portal hypertension. hps is associated with increased morbidity and mortality; thus, it is important to diagnose this entity as soon as possible for treatment to be administered. materials and methods: in a cross-sectional study, 40 children (6 months to 14 years ...
Kaposi sarcoma herpes virus (KSHV), also known as human herpesvirus-8, plays an important role in the pathogenesis of Kaposi sarcoma (KS), multicentric Castleman disease (MCD) of the plasma cell type, and primary effusion lymphoma. KSHV is rarely associated with the hemophagocytic syndrome (HPS), but when it does occur, it most occurs in immunocompromised patients. We report herein an unusual c...
Electrical stimulation of the frog glossopharyngeal (GP) nerve evoked slow hyperpolarizing potentials (HPs) in taste cells. This study aimed to clarify whether slow HPs were postsynaptically induced in taste cells. The slow HPs were recorded intracellularly with a microelectrode. When Ca2+ concentration in the blood plasma was decreased to approximately 0.5 mM, the amplitude of slow HPs reduced...
Hantavirus pulmonary syndrome (HPS) is a severe disease characterized by a rapid onset of pulmonary edema followed by respiratory failure and cardiogenic shock. The HPS associated viruses are members of the genus Hantavirus, family Bunyaviridae. Hantaviruses have a worldwide distribution and are broadly split into the New World hantaviruses, which includes those causing HPS, and the Old World h...
