Introduction: The sense of sight is one of the most vital human senses and help the environment gets most of its information. Whatever one's job is more subtle, more work will be given brightness. Good lighting, increase work efficiency and general physiological effects on people's moods. The relationship between low and high frequency illumination accidents there Methods: This study was con...
Introduction: Outdoor workers are exposed to heat from solar radiation and the atmospheric conditions, in addition to the heat from the working process, which is worse by global warming. The purpose of this study was to evaluate heat stress based on wet bulb globe temperature index and also to examine the relationship between WBGT and physiological indices among outdoor workers of Shabestar cit...
Introduction: Heat stress is considered as a serious risk factor to the health and safety of workers in most working environments, especially in outdoor works and jobs that workers are exposed to heat due to the working process. This study aimed to evaluate heat stress among workers of brick-manufacturing units in Qom city based on WBGT index as well as the relationship between WBGT and physiol...
the interaction between isatin-β-thiosemicarbazone (ibt) and calf thymus dna (ct-dna) was investigated in physiological buffer (ph 7.4) using neutral red (nr) dye as a spectral probe by uv–vis absorption and fluorescence spectroscopy, as well as viscosity measurements. the ibt is stabilized by intercalation in the dna ( k [ibt –dna] =1.03×105 m−1), and displaces the nr dye from the nr–dna comple...
Background: Data suggest that V. arctostaphylos, B. thunbergii var. atropurpurea, E. angustifolia and L. acanthodes may prevent gastric ulcers induced by Non-steroidal anti-inflammatory drugs (NSAIDs). Objective: To explore the ulcer-protective potential of these plants in indomethacin-induced gastric ulcers in rats. Methods: Saline, hydro-alcoholic extract of each plant (100, 400, 800 mg/...
