SINCE MYOCARDIAL INFARCT SIZE is the major contributor to the development of heart failure, interventions aiming to limit irreversible damage of ischemic myocardium are essential. In the clinical setting, reduction of myocardial oxygen demand and restoration of blood flow to the ischemic myocardium remain the primary targets to accomplish this goal, despite experimental evidence that reperfusio...

The fungal genus Knufia mostly comprises extremotolerant species from environmental sources, especially rock surfaces. The draft genome sequence of the rock fungus Knufia petricola presented here is the first whole-genome sequence of the only species among black fungi known to have a nonmelanized spontaneous mutant.

in the this research, the hydrocarbon generation potential of the gadvan formation as a probable source rock was investigated in the central part of the persian gulf at the borders of iran. type and maturity level of kerogen were investigated in six wells using the results of rock-eval pyrolysis and compared with results yielded by the modelling software program known as pars basin modeler (pbm...

eastern rock nuthatch (sitta tephronota) and western rock nuthatch (s. neumayer) are two closely related and sympatric species in iran, which have been known as the classical case of character displacement since 1950. nevertheless, some questions related their niche partitioning is still unanswered. this study was conducted to determine the diet differentiation, as an important niche dimension,...

The weathering of volcanic rocks contributes significantly to the global silicate weathering budget, effecting carbon dioxide drawdown and long-term climate control. The rate of chemical weathering is influenced by the composition of the rock. Rock-dwelling micro-organisms are known to play a role in changing the rate of weathering reactions; however, the influence of rock composition on bio-we...

Reducing the time required for initial integration of bone-contacting implants with host tissues would be of great clinical significance. Changes in osteoblast adhesion formation and reorganization of the F-actin cytoskeleton in response to altered topography are known to be upstream of osteoblast differentiation, and these processes are regulated by the Rho GTPases. Rac and RhoA (through Rho K...

AIMS Deleted in liver cancer 1 (DLC1), a member of RhoGTPase activating protein (GAP) family, is known to have suppressive activities in tumorigenicity and cancer metastasis. However, the underlying molecular mechanisms of how DLC1 suppresses cell motility have not been fully elucidated. Rho-kinase (ROCK) is an immediate down-stream effector of RhoA in mediating cellular cytoskeletal events and...

RhoA/Rho kinases (ROCK) play a critical role in vascular smooth muscle cell (VSMC) actin cytoskeleton organization, differentiation, and function and are implicated in the pathogenesis of cardiovascular disease. We have previously determined that an important step in the regulation of calcification is fetuin-A endocytosis, a process that is dependent on changes in the cytoskeleton, which, in tu...

INTRODUCTION Jasonia glutinosa is an endemic plant species of the Iberian Peninsula and Southern France traditionally used in infusions as a spasmolytic; this plant is also known as "té de roca" (rock tea) but there is no scientific evidence about the effects of this plant. AIM To evaluate the spasmolytic effect of rock tea. METHODS We have studied the in vitro effect of a rock tea extract ...
