objective: bioactive glass 45s5 is a surface reactive glass-ceramic biomaterial, developed in 1969. bag 45s5 with particle size of 20-60 nm has the ability of bone regeneration, broad spectrum antibacterial effect, repairs and replaces diseased or damaged bone. the aim of this study was to evaluate the antibacterial activity and determine mic and mbc values of nano-bag45s5 on streptococcus muta...

The production of conidia of entomopathogenic Beauveria bassiana by solid-state fermentation was studied for the development of a biocontrol agent against aphid Myzus persicae. The optimal conditions for conidia production on polished white rice were 40% moisture content, 25℃ culture temperature, 2-day-old seeding culture grown in 3% corn meal, 2% rice bran, 2% corn steep powder medium, initial...

of Research 1. Evaluation of BBM BBM of the flight hardware was evaluated by repeated culture experiment under the simulated conditions for space experiment. As a part of device development, materials of a fixed container (an EPDM bag) and the fixation ability of the fixatives were also evaluated. After long term storage (> one month) in the EPDM bag gave little damage on the fixed specimens wh...

Brief electrical or hormonal stimulation of the bag cell neurons of Aplysia triggers a long-lasting discharge during which alpha bag cell peptide (alpha-BCP) and other neuropeptides are released from the cells. We have carried out experiments, using both intact abdominal ganglia and isolated neurons, demonstrating that alpha-BCP acts directly on the bag cell neurons to influence cAMP levels and...

The proliferation of human bone marrow cells was studied in a liquid culture system without colony-stimulating factor. Bone marrow cells suspended in medium containing horse serum and fetal calf serum were incubated in the Teflon culture bag. During the first week there was an increase in the number of blast cells and early cells of the granulocytic series, both of which showed a high 3H-thymid...

Information on the use of disposable nappies in childhood was available for 296 testicular cancer cases and 287 population controls in Denmark. No association was found between disposable nappy use and the subsequent risk of testicular cancer in adulthood.

OBJECTIVE To evaluate the accuracy of urine sample collection methods among children suspected of having urinary tract infections. SUBJECTS AND METHODS Four methods for urine sample collection were evaluated in 1,067 children aged 0-16 years with suspected urinary tract infections over 2 months at Dr. Sami Ulus Children's Hospital. Within 30 min of collection, all specimens were sent to the l...

Here we report a simple new method for exposing cells to normoxic and hypoxic conditions using vacuum bags, normally employed for food storage, to establish and maintain low oxygen levels in vitro. Vacuum bags were gassed with a mixture containing specified levels of oxygen, then sealed, creating a hypoxic microenvironment for cells cultured in flasks placed therein. Oxygen levels in the gas mi...
