The vitreous is involved in multiple diseases when an incomplete posterior vitreous detachment (PVD) occurs. An incomplete PVD can lead to several pathological conditions. Such visually threatening conditions are traditionally of exclusive surgical interest. In contrast, pharmacological vitreolysis is the effort to reduce or eliminate the pathogenetic role of the vitreous solely by means of dru...

The 316 L Stainless Steel is widely used as structural material in marine applications and subject to localized pitting corrosion chlorinated environments. main aim of the present work development coatings that are alternately deposited by a combination Physical Vapor Deposition (PVD) Atomic Layer (ALD) techniques. Three different architectures PVD/ALD, ALD/PVD PVD/ALD/PVD were studied. layer A...

Robust dendrite morphogenesis is a critical step in the development of reproducible neural circuits. However, little is known about the extracellular cues that pattern complex dendrite morphologies. In the model nematode Caenorhabditis elegans, the sensory neuron PVD establishes stereotypical, highly branched dendrite morphology. Here, we report the identification of a tripartite ligand-recepto...

In a color image every pixel value composed of red, green and blue component and each of which ranges from 0 to 255 in case of 8-bit representation. In this paper, we have used pixel value differencing (PVD) method for secret data embedding in each of the component of a pixel in a color image. But when we use pixel-value differencing (PVD) method as image steganographic scheme, the pixel values...

CONTEXT Acute onset of monocular floaters and/or flashes represents a common presentation to primary care physicians, and the most likely diagnosis is posterior vitreous detachment (PVD). A significant proportion of patients with acute PVD develop an associated retinal tear that can lead to retinal detachment and permanent vision loss if left untreated. OBJECTIVE To quantify the association b...

BACKGROUND Although considered a cornerstone therapy, the efficacy and safety of aspirin for prevention of ischemic events in patients with peripheral vascular disease (PVD) remains uncertain. Thus, we aimed to evaluate aspirin use in both symptomatic and asymptomatic patients with PVD. METHODS An electronic search of databases was conducted from inception until January 2017 for all randomize...

BACKGROUND Atrial natriuretic peptide (ANP) and its receptor, NPRA, have been extensively studied in terms of cardiovascular effects. We have found that the ANP-NPRA signaling pathway is also involved in airway allergic inflammation and asthma. ANP, a C-terminal peptide (amino acid 99-126) of pro-atrial natriuretic factor (proANF) and a recombinant peptide, NP73-102 (amino acid 73-102 of proANF...

PURPOSE To investigate the effects of intravitreal injection of nattokinase (subtilisin NAT), a serine protease that is produced by Bacillus subtilis (natto), for induction of posterior vitreous detachment (PVD). METHODS Different doses of nattokinase (1, 0.1, or 0.01 fibrin-degradation units [FU]) or physiologic saline as a control were injected into the vitreous cavity of rabbit eyes. Scann...

AIMS To see whether the diabetic individuals identified by the Indian Diabetes Risk Score (IDRS) also have a higher prevalence of diabetes related complications. METHODS Type 2 diabetic subjects were selected from the Chennai Urban Rural Epidemiology Study in south India. Four field stereo retinal colour photography was done and diabetic retinopathy [DR] was classified according to Early Trea...
