Metabolic Carcinogenesis.

Several types of environmental, chemical and metabolic carcinogens exist both exogenously and endogenously. Humans are daily exposed to aforementioned carcinogens through various sources such as through water, air and food or through metabolic and inflammatory products. This chapter will summarize the links between exogenous and endogenous carcinogen exposure and their metabolism with the cancer pathogenesis and associated risks.

Daidzin improves neurobehavioral outcome in rat model of traumatic brain injury.

Traumatic brain injury (TBI) is associated with the etiology of multiple neurological disorders, including neurodegeneration, leading to various cognitive deficits. Daidzin (obtained from kudzu root and soybean leaves) is known for its neuroprotective effects through multiple mechanisms. This study aimed to investigate the pharmacological effects of Daidzin on sensory, and biochemical parameters, cognitive functions, anxiety, and depressive-like behaviors in the TBI rat model.

'Breast Cancer Resistance Likelihood and Personalized Treatment Through Integrated Multiomics'.

In recent times, enormous progress has been made in improving the diagnosis and therapeutic strategies for breast carcinoma, yet it remains the most prevalent cancer and second highest contributor to cancer-related deaths in women. Breast cancer (BC) affects one in eight females globally. In 2018 alone, 1.

Binge eating disorder during COVID-19.

With the onset of coronavirus disease in December 2019, the normal routine and lifestyle of the humans has adversely affected all over the world. This change in lifestyle not only increased the level of stress and anxiety, but also badly modified the eating habits during the lockdown period. This increased the rate of binge eating disorder in people who were already immune-compromised.

Climate beast: a potential threat for repercussions of disease status in Pakistan.

Pakistan is amongst the developing countries, which have been strongly affected by several emerging and re-emerging disease outbreaks as a consequence of climate change. Various studies have clearly demonstrated the impact of climate change on human health in Pakistan. This has increased the rate of morbidity and mortality, related not only to vector-borne, water-borne and food-borne diseases but has also contributed to the prevalence of neurological, cardiovascular and respiratory disorders.

Expression of DnMTs and MBDs in AlCl-Induced Neurotoxicity Mouse Model.

Alteration in DNA methylation after aluminum exposure has been shown to contribute in pathogenesis of Alzheimer's disease (AD). This study is aimed to determine the effect of Al exposure (42 and 60 days) on learning and memory and the expression of proteins involved in DNA methylation (MBD1, MBD2, MBD3, MeCP2 (methyl CpG binding protein 2), DnMT1 and DnMT3a). Male BALB/c mice were treated with AlCl for either 42 days or 60 days.

Aluminum Suppresses Effect of Nicotine on Gamma Oscillations (20-40 Hz) in Mouse Hippocampal Slices.

Background: Aluminum (Al) causes neurodegeneration and its toxic effects on cholinergic system in the brain is well documented. However, it is unknown whether and how Al changes oscillation patterns, driven by the cholinergic system, in the hippocampus.

Objective: We studied acute effects of Al on nicotinic acetylcholine receptors (nAChRs)-mediated modulation of persistent gamma oscillations in the hippocampus.

Cortex- and Amygdala-Dependent Learning and Nicotinic Acetylcholine Receptor Gene Expression is Severely Impaired in Mice Orally Treated with AlCl.

Recent industrialization has increased human exposure to bio-available aluminum (Al). If more Al enters the brain than leaves, Al concentration will rise in the brain leading to neurodegenerative disorders. The aim of the present study was to determine Al concentration, neurodegeneration, and nicotinic acetylcholine receptor (nAChR) gene expression in the cortex and amygdala after oral ingestion of Al salt.

Neuroprotective and Neurotoxic Implications of α7 Nicotinic Acetylcholine Receptor and Aβ Interaction: Therapeutic Options in Alzheimer's Disease.

Background: Alzheimer's disease, a neurodegenerative disorder, is characterized by accumulation of amyloid beta (Aβ) plaques, neurofibrillary tangles and loss of cholinergic neurons.

Literature Review: The localization of Aβ plaques particularly in the cholinergic neuron-rich areas has led to the discovery that Aβ binds to α7 nicotinic acetylcholine receptors (nAChRs) with very high affinity. This discovery has led to extensive exploration of the possible outcomes of this binding, ranging from the subcellular signaling pathways to its effects on behavioral and cognitive functions.

Aluminum-Induced Cholinergic Deficits in Different Brain Parts and Its Implications on Sociability and Cognitive Functions in Mouse.

Aluminum is associated with etiology of many neurodegenerative diseases specially Alzheimer's disease. Chronic exposure to aluminum via drinking water results in aluminum deposition in the brain that leads to cognitive deficits. The study aimed to determine the effects of aluminum on cholinergic biomarkers, i.

Memory Enhancing Effect of Black Pepper in the AlCl3 Induced Neurotoxicity Mouse Model is Mediated Through Its Active Component Chavicine.

Unlabelled: Black pepper (Piper nigrum Linn.) has vital pharmacological properties with profound effects on central nervous system. Neurotoxic agents like Aluminum Chloride (AlCl3) cause the oxidative stress and result in improper processing of amyloid proteins leading to accumulation of amyloid β plaques.

Cholinergic System and Post-translational Modifications: An Insight on the Role in Alzheimer's Disease.

Background: Alzheimer's disease (AD) is the most common form of old age dementia. The formation of amyloid plaques (Aβ), neurofibrillary tangles and loss of basal forebrain cholinergic neurons are the hallmark events in the pathology of AD.

Literature Review: Cholinergic system is one of the most important neurotransmitter system involved in learning and memory which preferentially degenerates in the initial stages of AD.

Alpha-lipoic acid-mediated activation of muscarinic receptors improves hippocampus- and amygdala-dependent memory.

Aluminum (Al) is a neurotoxic agent which readily crosses the blood-brain-barrier (BBB) and accumulates in the brain leading to neurodegenerative disorders, characterised by cognitive impairment. Alpha-lipoic acid (ALA) is an antioxidant and has a potential to improve cognitive functions. This study aimed to evaluate the neuroprotective effect of ALA in AlCl3-induced neurotoxicity mouse model.
