Several researchers are concentrated on cancellation of salt and pepper noise from the two-dimensional signals like digital images and uses several filters like mean filter, median filter, trimmed median filter etc. , for removal of noise. A novel approach has been implemented using a filter so called Additive White Median Filter (AWMF) for filtering the two-dimensional signal which uses a sche...

This article is devoted to the pharmaceutical development of medical hemostatic foam. The method parenchymal bleeding modeling in liver rats was used assess activity various concentrations aluminum and iron chloride. Also assessment sedimentation rate density samples foam made when polysorbates-20 -80 were added it concentration range 0-0,75%. It found that from point view its safety efficacy c...

Dynamic light scattering (DLS) measurements have been performed at 30 degrees C to see the effects of additives on the microstructure of gemini alkanediyl-alpha,omega-bis(dimethylcetylammonium bromide) surfactants, (Br-, n-C16H33N+Me2-(CH2)s-Me2- N+n-C16H33, Br-, 16-s-16, where s = 4, 5, 6). In pure aqueous solutions, the hydrodynamic diameter, Dh, was found to increase rapidly with geminis in ...

BACKGROUND Carbonic anhydrase inhibitors (CAI) reduce proximal reabsorption, activating tubuloglomerular feedback (TGF) and reducing glomerular filtration rate (GFR). Adenosine A(1) receptors (A(1)R) mediate the TGF response and stimulate proximal reabsorption. METHODS Clearance and micropuncture studies were performed in Wistar rats to determine whether blockade of A(1)R (KW3902 0.3 mg/kg i....

Controversial results obtained from human and animal studies on the prevention of heart disease by estrogens and progestins warrant a better understanding of nuclear hormone receptor function and interaction. To address this issue and taking into account that effects of synthetic progestins are not only referable to action through the progesterone receptor but may also be mediated by other ster...

Primordial cells presumably combined RNAs, which functioned as catalysts and carriers of genetic information, with an encapsulating membrane of aggregated amphiphilic molecules. Major questions regarding this hypothesis include how the four bases and the sugar in RNA were selected from a mixture of prebiotic compounds and colocalized with such membranes, and how the membranes were stabilized ag...

The authors conducted a genome-wide linkage scan and positional association analysis to identify the genetic determinants of salt sensitivity of blood pressure (BP) in a large family-based, dietary-feeding study. The dietary intervention was conducted among 1,906 participants in rural China (2003-2005). A 7-day low-sodium intervention was followed by a 7-day high-sodium intervention. Salt sensi...

Cosolvents are routinely used to modulate the (thermal) stability of proteins and, hence, their interactions with proteins have been studied intensely. However, less is known about their specific effects on protein-protein interactions, which we characterize in terms of the protein phase behavior. We analyze the phase behavior of lysozyme solutions in the presence of sodium chloride (NaCl), gua...

Scedosporium prolificans and Scedosporium apiospermum (Pseudallescheria boydii) cause pulmonary and disseminated infections refractory to most currently used antifungal agents in immunocompromised patients. We therefore investigated the potential antifungal activities of the triazoles itraconazole (ITC), voriconazole (VRC), and posaconazole (PSC) in combination with human polymorphonuclear leuk...
