Subacute studies of profenofos on mosquito fish, Gambusia affinis, were carried out for 20 days to assess the locomotor behavior and structural integrity of gill in relation to bioaccumulation and targeted enzyme acetylcholinesterase (AChE; EC 3.1.1.7). The sublethal concentration of 0.13 mg/L (1/5 of LC50) altered locomotor behavior such as distance traveled and swimming speed in exposed fish. This could be due to inhibition in the activity of acetylcholinesterase and deformities in the primary and secondary lamella of gill. The bioaccumulation values indicated that the accumulation of profenofos was highest in viscera followed by head and body. The average bioconcentration factor values are 254.83, 6.18, and 2.52 microg/g for viscera, head, and body. The findings revealed that profenofos is highly toxic even at sublethal concentrations to the mosquito fish, Gambusia affinis.

Background: Apolipoprotein E4 (apoE4) has been identified as the major genetic risk factor for late onset Alzheimer's disease (AD). Our lab has demonstrated that chronic administration of Aβ12-28P, a synthetic peptide that blocks apoE4/Aβ binding, in middle-aged transgenic AD mice significantly ameliorates pathology progression, resulting in reduced Aβ plaques deposition and cerebral amyloid angiopathy (CAA) along with improved memory and cognition. However, whether blocking apoE4/Aβ interaction by Aβ12-28P also has an ameliorating effect on the neuronal and cognitive function of old AD mice where Aβ pathology has been extensively developed remains unknown.

UIPS, CHANDIGARH, Punjab, India.
Background: Alzheimer's disease is a brain disorder that causes neurodegeneration and is linked with insulin resistance at molecular, clinical, and demographic levels. Defective insulin signaling promotes Aβ aggregation and accelerates Aβ formation in the brain leading to Type III diabetes.
Objective: The objective of this research project is to demonstrate a linkage if any between the risk of developing Alzheimer's disease and insulin resistance.

Integrating dietary interventions have been extensively studied for their health benefits, such as Alzheimer's disease, Huntington's disease, and aging. However, it is necessary to fully understand the mechanisms of long-term effects and practical applications of these dietary interventions for health. A 10-week intermittent fasting (IMF) regimen was implemented on the aging animals in the current study.

Background: Mitochondrial dysfunction and neuronal damage are major sign of cytopathology in Huntington's disease (HD), a neurodegenerative disease. Ubiquitin specific peptidase 11 (USP11) is a deubiquitinating enzyme involved in various physiological processes through regulating protein degradation. However, its specific role in HD is unclear.

Purpose: Essential tremor (ET) is a prevalent movement disorder, yet current therapeutic options remain limited. Emerging evidence implicates leucine-rich repeat and immunoglobulin-like domain-containing protein (Lingo-1) and neuroinflammation in the pathophysiology of ET. This study aimed to investigate whether agmatine, a biogenic amine neuromodulator attenuates tremors and modulates the expression of Lingo-1 and proinflammatory markers in a rodent model of ET.
