background and purpose: microorganism-based synthesis of nanostructures has recently been noted as a green method for the sustainable development of nanotechnology. nowadays, there have been numerous studies on the emerging resistant pathogenic bacteria and fungal isolates, the probable inability of bacteria and fungi to develop resistance against silver nanoparticles’ (snps) antibacterial, ant...
دست یابی به سیل ایده آل در ترمیم های کامپوزیتی یکی از مهمترین اهداف دندانپزشکی ترمیمی در سالهای اخیر بوده است. بررسی نفوذ رنگ رایج ترین شیوه مطالعه ریز نشت است. این روش از ارزیابی سه بعدی حساسیت کمتری دارد. به دلیل فقدان مطالعات ارزیابی ریزنشت کامپوزیت ها به روشfluid filtration در دندان های شیری، در این تحقیق بر آن شدیم تا میزان ریزنشت باندینگهایself etch و total etchرا در دندان های شیری به روش...
Tissue glucose levels affect the refractive index of the extracellular fluid. The difference in refractive index between the extracellular fluid and the cellular components plays a role in determining the reduced scattering coefficient (micro(s)') of tissue. Hence a physical correlation may exist between the reduced scattering coefficient and glucose concentration. We have designed and construc...
Cystoid macular oedema (CMO) is a major cause of reduced vision following intraocular surgery. Although the aetiology of CMO is not completely clarified, intraocular inflammation is known to play a major role in its development. The macula may develop cytotoxic oedema when the primary lesion and fluid accumulation occur in the parenchymatous cells (intracellular oedema) or vasogenic oedema when...
The choroid plexus and cerebrospinal fluid have recently begun to emerge as essential regulators of neural function. Factors produced by the choroid plexus are released into the ventricular environment and thus provide a rich source of extracellular signaling molecules throughout the central nervous system. Identified factors in the cerebrospinal fluid include growth factors, hormones, proteins...
1. Sodium and potassium transport rates were studied in normal human leucocytes exposed to iso-osmolal and hypo-osmolal extracellular fluid. 2. Hypo-osmolality of the extracellular fluid led to an increase in sodium influx and a decrease in potassium influx expressed as mmol h-’ kg-’ cell dry weight. The fall in potassium influx was smaller than the rise in sodium influx and was confined to the...
FIGURE 12-7 Acute renal failure (ARF). This figure depicts the most commonly used schema to classify and diagnostically approach the patient with ARF [1, 6, 9]. The most common general cause of ARF (60% to 70% of cases) is prerenal factors. Prerenal causes include those secondary to renal hypoperfusion, which occurs in the setting of extracellular fluid loss (eg, with vomiting, nasogastric suct...
Fluid overload is one of the major presentations in patients with late stage chronic kidney disease (CKD). Diabetes is the leading cause of renal failure, and progression of diabetic nephropathy has been associated with changes in extracellular fluid volume. The aim of the study was to assess the association of fluid overload and diabetes in commencing dialysis and rapid renal function decline ...
Ten ongoing studies designed to test the possibility that extracellular RNAs may serve as biomarkers in human disease are described. These studies, funded by the NIH Common Fund Extracellular RNA Communication Program, examine diverse extracellular body fluids, including plasma, serum, urine and cerebrospinal fluid. The disorders studied include hepatic and gastric cancer, cardiovascular diseas...
