This study was intended to investigate the antioxidant activities of different solvent fractions (hexane (HEX), chloroform (CHL), ethylacetate (ETHYL) and methanol (MET) fractions) extract Andrographis paniculata GC-MS profiling most active fraction (MET). The crude fractionated using vacuum liquid chromatography method. Antioxidant activity evaluated total phenolic content (TPC), flavonoid (TF...

Two experiments were conducted, first was to estimate maize seedling damage in farmers’ fields and a simulation experiment. This study aim investigate the impact of rodent pest species, crop semi-arid areas at pre-harvest, with view provide farmers appropriate information on management interventions. In fields, assessment done by counting number damaged or removed seedlings each planting ...

This study aimed to attain a comparison in pharmacokinetic parameters of ondansetron after transdermal (as invasomes gel) and oral solution) routes. Ondansetron is 5 ? hydroxytryptamine receptor antagonist used for chemotherapy radiotherapy induced nausea emesis. The was performed using Wistar albino rats weighing 200 ±20 g divided into two groups (6 each). A dose 0.28 mg ondansetron, eq...

Tobacco sperm cells contain intact mitochondria within their nuclei with a frequency of 0.35 [plusmn] 0.13 per cell. These inclusions appear to originate from mitochondria found among chromatids in the highly elongated metaphase plate of the dividing generative cell. These organelles are apparently captured during the reconstitution of the nuclear envelope. Only sperm cells were observed to con...

Laser frequency-modulated (FM) spectroscopy has been used as an axial probe of a laser-guided electric discharge in sodium-argon vapor contained in an optically accessible metal heat pipe oven. Absorption measurements in the region 23 106-23 881 cm-1 provided accurate line positions (&plusmn;<0.006 cm-1) for 141 transitions in the v' = 3-8 <-- v" = 0 and v' = 5-9 <-- v" = 1 bands of NaH (A1Sigm...

When the extracellular pH was increased from 7.6 to 9.8, Clostridium paradoxum, a novel alkalithermophile, increased its pH gradient across the cell membrane ((Delta)pH, pH(infin) - pH(infout)) by as much as 1.3 U. At higher pH values (>10.0), the (Delta)pH and membrane potential ((Delta)(psi)) eventually declined, and the intracellular pH increased significantly. Growth ceased when the extrace...
