Insights from the molecular docking analysis of compounds from with targets from causing urinary tract infection.

Antimicrobial resistance among bacterial strains has emerged out to be a serious threat and contributes to the loss of effectiveness of the common antibiotics. New Delhi metallo-β-lactamase-1 (blaNDM-1) is an enzyme present in several pathogenic bacteria with a high incidence in and plays a crucial role in the development of antibacterial resistance. Mur enzymes are also important alternative drug targets in addition to blaNDM-1 which are crucial for the survival of the bacteria.

Pharmacokinetics and relative bioavailability of tiamulin in broiler chicken as influenced by different routes of administration.

The bioavailability and pharmacokinetic disposition of tiamulin in broiler chicken were investigated after administration through the crop, drinking water, and feed at 40 mg/kg body weight. Residues of tiamulin in tissues of broiler chicken were also assessed. Plasma and tissue concentrations of tiamulin were analyzed by reverse-phase high-performance liquid chromatography (HPLC) method.

Gross, histopathological and immunohistochemical study on strobilocercus of Taenia taeniaeformis infection in the liver of laboratory rats (Rattus norvegicus) in India.

We report the detailed gross, histopathological and immunohistochemical study of Strobilocercus fasciolaris infection, the metacestodal stage of Taenia taeniaeformis, in the liver of laboratory Wistar rats. Necropsy examination of seventeen rats revealed transparent or white or cream to clear, thick walled cysts, 1 to 97 in number, measuring about 2mm to 12mm on one or many of the liver lobes and containing strobilocercus of Taenia taeniaeformis. Histopathological examination revealed the presence of the cross-section of larva surrounded by a thick fibrous capsule and moderate infiltration of lymphocytes, plasma cells and a few eosinophils.

Effect of sulphated polysaccharides on erythrocyte changes due to oxidative and nitrosative stress in experimental hyperoxaluria.

Kidney stones are known to haunt humanity for centuries and increase in oxalate is a predominant risk factor for stone formation. The present study was initiated with a notion to study the oxidative and nitrosative stress on erythrocytes under oxalate stress and the putative role of sulphated polysaccharides. Hyperoxaluria was induced in two groups by the administration of 0.

Role of sulphated polysaccharides from Sargassum Wightii in Cyclosporine A-induced oxidative liver injury in rats.

Background: Seaweeds or marine algae have long been made up a key part of the Asian diet, and as an antioxidant, sulphated polysaccharides have piqued the interest of many researchers as one of the ocean's greatest treasures. The present investigation suggests the therapeutic potential of sulphated polysaccharides from marine brown algae "Sargassum wightii" in Cyclosporine A (CsA)- induced liver injury. CsA is a potent immunosuppressive agent used in the field of organ transplantations and various autoimmune disorders.

Mitochondrial dysfunction in an animal model of hyperoxaluria: a prophylactic approach with fucoidan.

Oxalate/calcium oxalate toxicity is mediated through generation of reactive oxygen species in a process that partly depends upon events that induce mitochondrial damage. Mitochondrial dysfunction is an important event favoring stone formation. The objective of the present study was to investigate whether mitochondria is a target for oxalate/calcium oxalate and the plausible role of naturally occurring glycosaminoglycans from edible seaweed, fucoidan in ameliorating mitochondrial damage.

Beneficial effects of sulfated polysaccharides from Sargassum wightii against mitochondrial alterations induced by Cyclosporine A in rat kidney.

Sulfated polysaccharides from marine seaweeds are receiving continuous attention owing to their wide therapeutic applications and are known to inhibit free radical generation. It has been well known that mitochondria are the major sources as well as the target of free radicals. The renal tubules have high density of mitochondria and therefore show structural and functional defects in acute renal failure.

Oxidative and nitrosative stress mediated renal cellular damage induced by cyclosporine A: role of sulphated polysaccharides.

Oxidative and nitrosative stress are known to exert various adverse effects on biological systems and this seems to be one of the major contributor of nephrotoxicity induced by cyclosporine A (CsA), which is a major clinical challenge, despite its potent immunosuppressive effect. Sulphated polysaccharides of marine origin are well known for its antioxidant properties, among its other biological applications. CsA administration (25 mg/kg body weight, orally, for 21 d) showed increased level of oxidants and xanthine oxidase activity.

Sulphated polysaccharides: new insight in the prevention of cyclosporine A-induced glomerular injury.

The scope of the current study was to examine the possible effects of sulphated polysaccharides against cyclosporine A-induced glomerular injury. Nephrotoxicity induced by cyclosporine A continues to be a major problem despite its potent immunosuppressive action. Adult male albino rats of Wistar strain were categorized into four groups.

Physico-chemical alterations of urine in experimental hyperoxaluria: a biochemical approach with fucoidan.

Urinary supersaturation-induced crystal formation has been attributed as one of the key factor for the pathogenesis/progression of lithogenesis. This study was aimed at investigating whether fucoidan, a naturally occurring sulfated glycosaminoglycan, could ameliorate the biochemical changes in urine induced by stone formation. Two groups of male albino Wistar rats (120+/-20 g) received 0.

Protective role of sulphated polysaccharides in abating the hyperlipidemic nephropathy provoked by cyclosporine A.

Cyclosporine A (CsA)-induced nephrotoxicity hampers the immense therapeutic potential of such a powerful immunosuppressant. The present study was conducted with an aim to explicate the contribution of sulphated polysaccharides (SPS) in abating the lipid abnormalities induced by CsA in the rat kidney. Hyperlipidemia associated with nephrotic syndrome may play a role in the worsening of renal function.

Renal peroxidative changes mediated by oxalate: the protective role of fucoidan.

Oxalate, one of the major constituents of renal stones is known to induce free radicals which damage the renal membrane. Damaged epithelia might act as nidi for stone formation aggravating calcium oxalate precipitation during hyperoxaluria. In the present study, the beneficial effects of fucoidan on oxalate-induced free radical injury were investigated.

Lupeol ameliorates aflatoxin B1-induced peroxidative hepatic damage in rats.

Aflatoxins are potent hepatotoxic and hepatocarcinogenic agents. Reactive oxygen species and consequent peroxidative damage caused by aflatoxin are considered to be the main mechanisms leading to hepatotoxicity. The present investigation aims at assessing the hepatoprotective effect of lupeol, a pentacyclic triterpene isolated from the stem bark of Crataeva nurvala, on aflatoxin B(1) (AFB(1))-induced hepatotoxicity in a rat model.

Evaluating the effect of sulphated polysaccharides on cyclosporine a induced oxidative renal injury.

Cyclosporine A (CsA) has been universally used as an immunosuppressant for the management of organ transplantation and various autoimmune diseases. However, nephrotoxicity due to CsA remains to be an important clinical challenge. In the present investigation, an attempt has been made to appraise the effect of sulphated polysaccharides on oxidative renal injury caused by CsA.
