Staphylococcus aureus continually threatens the safety of meat products, especially multidrug-resistant (MDR) strains. The screening MDR S. prevalence in marketed products Saudi Arabia was conducted via molecular identification resistance genes (cfr, gyrA, and gyrB) that occurred isolated bacteria. green phytosynthesis selenium nanoparticles (Se-NPs) also conducted, using fruits’ extract Phylla...

Objective(s):Hyperglycemia mediated oxidative stress plays a key role in the pathogenesis of diabetic complications like nephropathy. In the present study, we evaluated the effect of ethanolic extract of Ensete superbum seeds (ESSE) on renal dysfunction and oxidative stress in streptozotocin-induced diabetic rats. Materials and Methods:Glucose, HbA1c, total protein, albumin, renal function mar...

A proteolytic enzyme from L. muta stenophrys was isolated by gel filtration on Bio Gel P-100 followed by FPLC on MONO S column. The enzyme exhibited proteolytic activity toward casein, hemoglobin and fibrinogen with a pH optimum around 10. The activity was inhibited by EDTA while trypsin inhibitors were not inhibitory. It is a glycoprotein, Mr 14 kDa with a high content of Asp, Glu, and Leu res...

A strain of Pseudomonas aeruginosa has been shown to produce an enzyme that lyses viable cells of Staphylococcus aureus. The maximal yield of the enzyme was obtained from shake flask cultures of P. aeruginosa which were grown for 18 to 22 hr at 37 C in Trypticase Soy Broth. A 333-fold purification of the enzyme was obtained by acetone precipitation of the culture liquor, followed by column chro...

Activation of plasminogen by agents such as tissue-type plasminogen activator (tPA), yields plasmin, lyses fibrin, and thereby restores flow to blood vessels occluded by thrombi. Because tPA binds to fibrin, as does plasminogen, at low doses, tPA-mediated generation of plasmin is localized, rendering tPA clot selective. This result, plus its short half-life (4.5 minutes), led to the hope that i...

During the initial stages of intraperiplasmic growth of Bdellovibrio bacteriovorus on Escherichia coli, the peptidoglycan of the E. coli becomes acylated with long-chain fatty acids, primarily palmitic acid (60%) and oleic acid (20%). The attachment of the fatty acids to the peptidoglycan involves a carboxylic-ester bond, i.e., they were removed by treatment with alkaline hydroxylamine. Their l...

Trichoplax is a small disk-shaped marine metazoan that adheres to substrates and locomotes by ciliary gliding. Despite having only six cell types and lacking synapses Trichoplax coordinates a complex sequence of behaviors culminating in external digestion of algae. We combine live cell imaging with electron microscopy to show how this is accomplished. When Trichoplax glides over a patch of alga...

One inflammatory event that may be involved in erythema nodosum leprosum (ENL) is the activation of complement, and thalidomide could suppress ENL by inhibiting its activation. To determine if thalidomide inhibits the activation of complement, we first incubated normal serum with Mycobacterium leprae or with zymosan in the presence of thalidomide. Residual functional complement was then determi...

considering the ease of isolation and high expansion potential of pulp stem/progenitor cells isolated from wisdom and primary teeth they have been implicated as the most reliable autologous cell source in dental tissue engineering. meanwhile, different isolation methods have remarkable impacts on the expansion potential of adult stem cells. in enzymatic digestion method extracted teeth as denta...
