background and objectives: in marine actinomycetes, carotenoid production occurs in constitutive, light-dependent or cryptic manner. the present work deals with the fermentative production of carotenoids from marine actinomycetes. materials and methods: marine actinomycetes namely streptomyces strain aqbmm35 was isolated from the marine sponge mycale mytilorum collected from south west coast of...

BACKGROUND AND PURPOSE The prognostic value of dynamic contrast-enhanced MR imaging in patients with glioblastoma is controversial. We investigated the added prognostic value of dynamic contrast-enhanced MR imaging to clinical parameters and molecular biomarkers in patients with glioblastoma by using histogram analysis. MATERIALS AND METHODS This retrospective study consisted of 61 patients w...

this experiment was arranged as a strip-plot on the base of a completely randomized block design with three replications to study the effect of tillage (whether in day or night or in day by light-proof cover) and application of reduced dosage of imazethapyr and trifluralin on weed control, yield and yield components of chickpea. main plots consisted of tillage methods and subplots consisted of ...

the aim of the present research was to study the effects of weak cation exchange resins, polacrilex with exchangeable h+ and polacrillin potassium and strong cation exchange resin sodium polystyrene sulfonate on water uptake behavior of ranitidine hydrochloride. drug resin complexes (drc) were prepared and evaluated for the percentage of moisture gain when placed in a humidity chamber at 40e2 °...

PURPOSE A prior study demonstrated that pretreatment with phenyl-N-tert-butylnitrone (PBN), a synthetic antioxidant and free radical trapping agent, protects rats from light-induced photoreceptor cell death. The objective of the present study was to elucidate the molecular mechanism of PBN neuroprotection. METHODS Sprague-Dawley rats (5-6 weeks old) raised in dim (5 lux) cyclic light (12 hour...

the aim of the present study was to find out whether training in a specific visual condition was an advantage in learning the accuracy of skill performance in the basketball free throw shooting. 28 boys (mean age: 17.14+0.75 years) voluntarily participated in the study and practiced in two groups: with normal light (control group), and in a specific visual condition (focusing light on rim of ba...

The Brillouin shift and width for poly(acrylic acid) hydrogels have been obtained as a function of gel network volume fraction using a five-pass Fabry-Pdrot interferometer. A conspicuous peak has been observed in the Brillouin shift at high volume fraction. The results are discussed in the light of a theory for the Brillouin light-scattering from gels proposed by Marqusee and Deutch-

The incorporation of labelled leucine was measured in protein fractions of muscle in intact control and dystrophic female hamsters and also in cell-free preparations obtained from these animals. The labelling of the soluble sarcoplasmic protein fraction, the microsomal protein fraction and the sarcolemma protein fraction was increased in the dystrophic hindleg muscle. The specific radioactiviti...

the disease of thalassemia major requires mangement by repeated transfusions of packed cell and iron chelators such as deferoxamine. today, serum ferritin is used for estimation of adequacy of the management. as the most morbidities and mortalities of the disease are the consequences of cardiac complications. echocardiography is periodically periodically performed along with the management. in ...

In this paper, the influence of the constituent volume fractions by changing the values of the power-law exponent with uniform pressure on the vibration frequencies of reinforced functionally graded cylindrical shells is studied. The FGM shell with ring is developed in accordance to the volume fraction law from two constituents namely stainless steel and nickel. These constituents are graded th...
