Effects of high-intensity chronic noise on spatial memory in male versus female rats.

The detrimental effects of high-intensity noise on the auditory system and emotional status, including the induction of anxiety, are well documented. Preclinical as well as epidemiological and clinical studies have solidly established differential responses between males and females to various stressful stimuli, including high-intensity white noise (HIWN). However, whether chronic exposure to noise affects cognitive functions and whether this effect is sex dependent has not been adequately addressed.

ONYCHOLYSIS AS A COMPLICATION OF TAXANE-BASED CHEMOTHERAPY WITH CONCOMITANT CRYOTHERAPY IN BREAST CANCER PATIENTS: TWO CASE REPORTS.

Nail changes are a common side effect of taxane chemotherapy, although onycholysis is quite a rare complication the correct management of which is poorly standardized. These case reports provide a description and analysis of onycholysis, a rare but noteworthy complication observed during taxane-based chemotherapy with concomitant cryotherapy in two patients with breast cancer. Despite prophylactic measures, both cases experienced nail complications during Paclitaxel treatment, underlining the complex nature of onycholysis during taxane therapy and highlighting the critical role of nail assessment and infection screening.

Propionic acid affects the synaptic architecture of rat hippocampus and prefrontal cortex.

It is well documented that propionic acid (PPA) produces behavioral, morphological, molecular and immune responses in rats that are characteristic of autism spectrum disorder in humans. However, whether PPA affects the ultrastructure and synaptic architecture of regions of autistic brain has not been adequately addressed. Earlier we show that single intraperitoneal (IP) injection of PPA (175 mg/kg) produces superficial changes in the spatial memory and learning of adolescent male Wistar rats.

Differential effects of aging on hippocampal ultrastructure in male vs. female rats.

Age-related decline in physical and cognitive functions are facts of life that do not affect everyone to the same extent. We had reported earlier that such cognitive decline is both sex- and context-dependent. Moreover, age-associated ultrastructural changes were observed in the hippocampus of male rats.

Short- and long-term effects of chronic toluene exposure on spatial memory in adolescent and adult male Wistar rats.

Addiction to toluene-containing volatile inhalants is of significant medical and social concern, particularly among youth. These concerns are underscored by the fact that the majority of adult abusers of toluene started as teenagers. Surprisingly, however, the lasting effects of chronic toluene exposure, especially in various age groups, have not been well investigated.
