1. Ketone-body utilization in fed and starved adult and suckling rats has been investigated by measuring arterio-venous differences across the brain. Venous blood was collected from the confluence of sinuses and arterial blood from the femoral artery in adult rats and by cardiac puncture in suckling rats. 2. During starvation the arterio-venous difference of ketone bodies increased in proportio...

Phytases have been one of the focal enzymes for animal nutrition during the past two decades. In this work, the use of wheat bran as substrate for phytase production in Solid State Fermentation (SSF) was studied. In order to find the best fermentation conditions for phytase production using a laboratory strain indentified as Aspergillus niger, three different pretreatments (1: wheat bran withou...

BACKGROUND Platelet-rich plasma (PRP) preparations are a common treatment in osteoarthritis (OA) and inflammatory synovitis. However, there is ambiguity regarding the ideal concentration of leukocytes and platelets in these preparations necessary to induce an adequate anti-inflammatory and anabolic response in joint tissues, such as the synovial membrane. This research aimed to study, in normal...

This study assessed the potential of omega-3 long chain polyunsaturated fatty acids (n-3 LC-PUFA) enrichment in red earthworm (Eisenia fetida, REW), via addition fish oil (FO, anchovy oil) to culture-compost. FO compost was tested at graded inclusion doses (0, 2.5, 5 and 10 g/100 g compost) for different timeperiods, up 96h. Dose, time, as well dose time interactions had significant effects on ...

This study focused on the production of phytohormone indole-3-acetic acid (IAA) using tomato plant tissues as feedstock and highlighting its growth promotion effect seedlings. Twelve actinobacterial strains were screened for IAA under standard conditions strain Streptomyces plicatus PT2 was selected a promising producer. The establishment to increase by S. conducted Plackett-Burman mathematical...

Polystyrene (PS) is the most widely used plastic polymer. It mainly to produce disposable products. Due its resistance degradation, PS can remain in environment for a long time. Its mechanical, physical and biological actions determine release of smaller fragments, which are able penetrate organisms accumulate target organs. Fertilized Danio rerio eggs were exposed concentrations 10 20 mg/L flu...

The alterations in the activities of acid and alkaline phosphatase are good indicators stress due to exposure fish any toxicant. perturbations their may result decreased immune responses intestinal microflora activity. In present study, effect sublethal concentrations lindane (0.025, 0.05 0.1 mg/l) different tissues C. punctatus exposed for 96h has been studied. data showed decrease (AcP) activ...
