Left ventricular (LV) diastolic dysfunction is a fundamental impairment in congestive heart failure (CHF). This study examined LV diastolic function in the canine model of CHF induced by chronic coronary embolization (CCE). Dogs were implanted with coronary catheters (both left anterior descending and circumflex arteries) for CCE and instrumented for measurement of LV pressure and dimension. He...
در کار پژوهشی حاضر، الکترود کربن سرامیک تهیه شده به روش سل- ژل توسط نانوکامپوزیتی از اصلاحگرهای نانولوله های کربنی چند دیواره (MWCNT) و مایع یونی (IL) اصلاح شد. فرآیند اصلاح از طریق قطرهگذاری سوسپانسیونی ازMWCNT/IL در دی متیل فرم آمید و آب بر سطح الکترود کربن سرامیک صورت گرفت. مطالعات الکتروشیمیائی نشان داد که الکترود کربن سرامیک اصلاح شده با کامپوزیت نانولولههای کربنی چنددیواره و مایع یون...
A collimated Au source was used to determine the charge collection efficiency (CCE) at several locations along the length of a 3.4 x 3.4 x 5.5 mm CdZnTe bar detector both in planar configuration and with Frisch collars of varying length. For each configuration, a 0.50 mm long region spanning the width of the device was irradiated with 411 keV gamma rays produced by a neutron activated gold foil...
PURPOSE OF REVIEW To reiterate the necessity of integrating echocardiography in the management of shocked patients and to propose a step-by-step functional evaluation of hemodynamics proven to optimize hemodynamic monitoring and to adapt the treatment. RECENT FINDINGS Echocardiography has become the cornerstone to hemodynamic monitoring. By providing real-time images, echocardiography has the...
The objective of this retrospective field study was to evaluate the effect of chronic clinical endometritis (CCE) on days open in German Holstein Friesian cows. Two hundred and sixty-four cows diagnosed with CCE from day 14 to 42 postpartum were included in this study. A Cox’s proportional hazards regression model with stepwise forward selection for days open was used and the variables type of ...
Ca(2+)-sensitive adenylyl cyclases (ACs) orchestrate dynamic interplay between Ca(2+) and cAMP that is a crucial feature of cellular homeostasis. Significantly, these ACs are highly selective for capacitative Ca(2+) entry (CCE) over other modes of Ca(2+) increase. To directly address the possibility that these ACs reside in discrete Ca(2+) microdomains, we tethered a Ca(2+) sensor, GCaMP2, to t...
Contraction regulates heart development via a complex mechanotransduction process controlled by various mechanical forces. Here, we exploit zebrafish embryos as an in vivo animal model to discern the contribution from different mechanical forces and identify the underlying mechanotransductive signaling pathways of cardiogenesis. We treated 2 days postfertilization zebrafish embryos with Blebbis...
Hyperglycemia alters cardiac function and often leads to diabetic cardiomyopathy as cardiomyocyte apoptosis causes a hypertrophied heart to deteriorate to dilation and failure. Paradoxically, many short-term animal models of hyperglycemia protect against ischemia-induced damage, including apoptosis, by limiting Ca(2+) overload. We have determined that, like nonexcitable cells, both neonatal and...
in the present work, the electrooxidation of formic acid and formaldehyde; potentially important fuels for future fuel cells, was investigated on the fe3o4@pt core-shell nanoparticles/carbon-ceramic electrode (fe3o4@pt/cce). the fe3o4@pt nanoparticles were prepared via a simple and fast chemical method and their surface morphology, nanostructure properties, chemical composition, crystal phase, ...
We study the ground-state properties of a dilute gas of strongly-interacting fermions in the framework of the coupled-cluster expansion (CCE). We demonstrate that properties such as universality, opening of a gap in the excitation spectrum and applicability of s-wave approximations appear naturally in the CCE approach. In the zero-density limit, we show that the ground-state energy density depe...
