In vitro studies represent a reliable model to investigate the action of several homeopathic medicines or even high diluted/succussed substances on cell function and much evidence concerning a critical reappraisal about basic research in homeopathy has appeared. Human granulocytes are a good promising cellular model due to their involvement in inflammatory and immune response and to their rathe...

Porins from outer membrane of Gram-negative bacteria have a highly stable structure. Our previous studies on porin from Paracoccus denitrificans showed that the outer membrane protein porin is extremely stable toward heat, pH, and chemical denaturants. The major question we have addressed in this paper is whether the high stability of porin is a consequence of the beta-barrel structure and whet...

in this research, effect of bovine serum albumin (bsa) on motility and fertility of indigenous rooster spermatozoa was evaluated using 20 and 48 indigenous roosters and hens, respectively. semen was collected and pooled. in the first experiment, the pooled semen was diluted and divided into four aliquots.the treatments were included the diluted semen without bsa and with 1% bsa; in each group, ...

We outline a scenario of galaxy formation in which the gas in galaxy-forming regions was preheated to high entropy by vigorous energy feedback associated with the formation of stars in old ellipticals and bulges and with AGN activity. Such preheating likely occurred at redshifts z ∼ 2 – 3, and can produce the entropy excess observed today in low-mass clusters of galaxies without destroying the ...

In the CleanSky 2 ComAir study, subject tests were conducted in Fraunhofer Flight Test Facility cabin mock-up. This mock-up consists of front section a former in-service A310 hosting up to 80 passengers. 12 sessions outdoor/recirculation airflow ratio was altered from today’s typically applied fractions 88% recirculation fraction. leads increased relative humidity, carbon dioxide (CO2) and Tota...

The photo catalytic oxidation of Surfactant Hexadecyltrimethyl-ammonium bromide in aqueous diluted solution has been investigated. Compressed air was used as oxidant and the temperature was maintained at 25-30°C. Effect of UV rays alone and in combination of hydrogen peroxide (H O ) and titanium 2 2 dioxide (TiO ) on Hexadecyltrimethyl-ammonium bromide (C H NBr) was recorded. Finally, from HPLC...

When small tubes (75 by 10 mm), containing 1 or 2 ml of SIM medium (Difco) or Trypticase Agar Base (semisolid) (BBL), are preheated to 37 C, "stabinoculated" from a young agar slant culture, and incubated in a water bath at 37 C, motility may be observed in a fraction of the time required by the methods usually employed with these media. In a series of cultures which were studied, motility coul...

The effect of using preheated whey protein isolate (WPI) to replace part of the poultry meat proteins in batters formulated with different salt levels was studied. Substitution with 2% preheated whey proteins followed by cold set gelation (16 h at 1 C) significantly (P < 0.05) improved binding and water holding capacity of the raw batters. In the cooked state, WPI substitution reduced cook loss...

The rate of heat loss from legs and feet (HLEG) w a s studied in resting pigeons preheated to a body temperature (43-l°C) close to those recorded during flight. The experimental system was designed to allow the calculation of HLEG from whole-body cooling rates following exposure of the legs and feet to various combinations of wind speed (0-75 km h") and air temperature (5-25 °C). The pigeons re...
