Fishes are often exposed to environmental sounds such as those associated with shipping, seismic experiments, sonar and/or aquaculture pump systems. While efforts have been made to document the effects of such anthropogenic (human-generated) sounds on marine mammals, the effects of excess noise on fishes are poorly understood. We examined the short- and long-term effects of increased ambient so...

Low frequency noise characteristics of gate and drain currents are investigated for prestressed and poststressed AlGaN/GaN high electron mobility transistors. High reverse bias voltage stresses on the gate stack changes both drain and gate current noise. A temporary increase in drain current noise was observed during stress which recovered to prestress level a few weeks later. This is explained...

abstract background: advancements in neonatal intensive care unit (nicu) science and technology have increased the survival rate of preterm infants. despite these advances, they are still facing with neurobehavioral problems. noise level in nicu is a potential source of stress for preterm infants. it should be decreased to the standard level as much as possible. the purpose of this study was to...

There is increasing evidence that individuals in many species avoid areas exposed to chronic anthropogenic noise, but the impact of noise on those who remain in these habitats is unclear. One potential impact is chronic physiological stress, which can affect disease resistance, survival and reproductive success. Previous studies have found evidence of elevated stress-related hormones (glucocort...

Past research has emphasized the association between stress and the manifestation of psychotic symptoms in schizophrenia, yet relatively little is known about how environmental stressors affect cognitive processes in the illness. The present study sought to determine the effects of a loud noise stressor on a range of cognitive tasks, including spatial working memory (SWM), short-term visual mem...

Background: Induction of cellular response after exposure to electromagnetic fields is limited to coherent fields. An incoherent noise field is supposed to suppress the bioeffects of regular RF electromagnetic fields. The purpose of this study was to investigate the effect of GSM mobile phone-induced radiofrequency (RF) on the induction of oxidative stress in SP2/0 cell line. Materials and Meth...

Frequent blood sampling from males rats was used to study hypothalamic-pituitary-adrenal (HPA) axis activation during arthritis and its association with diminished responses to acute psychological stress. In control rats, corticosterone release occurred in a series of 13 +/- 1 pulses per 24 h. Induction of arthritis by Mycobacterium-adjuvant injection initially increased the rate of hormone rel...

Indigofera tinctoria and Scoparia dulcis are being widely used in Indian folk medicine for the treatment of various disorders. Environmental noise pollution is thought to be an important factor for many health problems and it causes immune abnormalities. In the present study immune-regulating potential of I. tinctoria and S. dulcis aqueous extracts on innate and adaptive immune system of wistar...

Endocrine responses to noise stress and anxiety-related behaviors were measured in groups of ovariectomized, estradiol-treated female rats given central infusions of oxytocin. Control animals receiving isotonic saline showed a large increase in plasma corticosterone concentrations in response to 10 min of white noise. This response to noise stress was significantly and dose dependently decrease...

Anthropogenic noise can have important physiological and behavioral effects on wild animals. For example, urban noise could lead to a state of chronic stress and could alter the development of the hypothalamus-pituitary-adrenal (HPA) axis. Supporting this hypothesis, several studies have found that human disturbance is associated with increased circulating corticosterone (CORT) levels. However,...
