The environmental photoperiod plays an important role in regulation of seasonal reproductive events. However, with reference tooestrogen status the exact mechanism involved in testicular seasonality is still unclear in general and especially in long-day breeder golden hamster, Mesocricetus auratus. Therefore, in the present study we explored the ef...

Female reproductive physiology is greatly dependent on tight regulation of metabolic and survival factors. Photoperiod regulates female reproductive rhythms but very less information exists explaining whether photoperiod could modulate thyroid hormone homeostasis, metabolic/energy parameters along with survival, proliferation and gap junction prote...

Photoperiod modulates reproductive physiology at multiple levels in seasonally breeding animals. Golden hamsters are long-day breeders that diminish their fertility during the short days. Photoperiod is known to regulate hormonal milieu and uterus is a hormone-sensitive dynamic tissue. However, there is lack of molecular insight regarding the impac...

The association between inflammation and metabolic disturbances leads to various female pathophysiological conditions. Bacterial lipopolysaccharide (LPS), found in the outer membrane of gram-negative bacteria, elicits an oxidative and inflammatory response that profoundly interferes with female reproductive health. We investigated the ameliorative...

Ever-increasing occurrence of plastic-manufacturing industries leads to environmental pollution that has been associated with declined human health and increased incidence of compromised reproductive health. Female subfertility/infertility is a complex phenomenon and environmental toxicants as well as lifestyle factors have a crucial role to play....

Several factors are responsible for declined male and female reproductive potential such as altered lifestyle, nutritional deficiency, global industrialization and increased exposure to environmental toxicants.The World Health Organization documents that around15%couples face the problems of infertility but its underlyinga etiology and treatment st...

Oxidative Damage and Apoptosis Induction by L-thyroxine in the Spleen of a Tropical Bird Perdicula asiatica: Rescue by Melatonin

Many mammalian species are able to respond to annual changes in day length by adaptive alterations in physiological as well as in behavioural states in anticipation of the coming season. Seasonal fluctuations in reproductive status have evolved as an adaptive mechanism to cope with seasonal energy availability. However, in order to elucidate the mo...

Ultraviolet radiation (UVR) is classified as a complete carcinogen as it acts as both mutagen and non-specific damaging agent. By damaging the skin's cellular DNA, excessive UVR produces genetic mutations that can lead to skin cancer. Considering this, it can be suggested that the exposure to UVR triggers a complex cascade of pathological symptoms...

Ultraviolet radiation is causative of generation of reactive oxygen species (ROS) in the body that significantly affects normal physiology and disturbs homeostasis. In the present study we investigated the effect of UV-A radiation exposure on the first line of defence system such as skin and vital organs such as liver, kidney and spleen of Rattus n...
