BACKGROUND: Increasing of oxygen consumption in fast-growing broiler chickens is associated with the more pronounced occurrence of right ventricular hypertrophy and ascites. While, rearing of susceptible chickens in dark condition could reduce the metabolic rate of birds and hence the incidence of ascites. OBJECTIVES: The present study was designed to investigate a comparative study on the inf...

Background: Potassium permanganate (PP) is a highly corrosive and deadly agent with a reported lethal dose of 10 g in adults. In this report, successful treatment of a patient poisoned with three times the lethal dose of PP is presented, and effective and early approach to such emergency toxicologic condition is discussed. Case Presentation:A 24-year-old woman presented to emergency room of our...

introduction: the a im of this study is the evaluation of the effect of antimicrobial photodynamic therapy with radachlorin on staphylococcus aureus and escherichia coli. new windows are open in the antimicrobial field so-call photodynamic therapy that incorporates a nonpoisonous photosensitizer (ps) with innocuous special wavelength photons to excite the ps. methods: two strains of bacteria us...

In a small, pitch-dark room at Baylor College of Medicine in Houston, Texas, a homing pigeon stands on a metal platform, its wings restrained in a leather harness and its head held in place by a plastic arm. The platform sits in the center of a 2-foot cubic frame containing electricity-conducting coils—one on every face of the cube. The coils are programmed to precisely deliver magnetic fields ...

Detection threshold in cone photoreceptors requires the simultaneous absorption of several photons because single photon photocurrent is small in amplitude and does not exceed intrinsic fluctuations in the outer segment dark current (dark noise). To understand the mechanisms that limit light sensitivity, we characterized the molecular origin of dark noise in intact, isolated bass single cones. ...

The irreducible upscattering of cold dark matter by cosmic rays opens up the intriguing possibility detecting even light in conventional direct detection experiments or underground neutrino detectors. mechanism also significantly enhances sensitivity to models with very large nuclear scattering rates, where atmosphere and rock overburden efficiently stop standard non-relativistic particles befo...
