Astrocytes and microglia, the immune competent cells of central nercous system, can be activated in response to metabolic signals such as obesity and hyperleptinaemia. In rats, maternal exposure to nicotine during lactation leads to central obesity, hyperleptinaemia, leptin resistance and
The hypothalamus controls food intake and energy expenditure. In rats, maternal exposure to nicotine during breastfeeding alters the hypothalamic circuitry of the adult offspring, resulting in leptin resistance, neuropeptides changes and gliosis. Tobacco smoke exposure during lactation causes
The area postrema is a densely vascularized small protuberance at the inferoposterior limit of the fourth ventricle, outside of the blood-brain barrier. This structure, besides to induce emetic reflex in the presence of noxious chemical stimulation, has a multifunctional integrative capacity to send
Cigarette smoke exposure during pregnancy into infancy affects brain growth and development in both short and long term (into adulthood). Using a mouse model of pre- into post- natal cigarette smoke exposure (SE), we aimed to determine the effects on brain derived neurotrophic factor (BDNF) and its
Ornithine decarboxylase (ODC) and the polyamines play an essential role in brain cell replication and differentiation and polyamines also regulate the function of nicotinic acetylcholine receptors (nAChRs). We administered alpha-difluoromethylornithine (DFMO), an irreversible inhibitor of ODC, to
The brains of people with Alzheimer's disease (AD) display several characteristic pathological features, including deposits (plaques) of beta-amyloid 1-42 (Abeta1-42), intraneuronal accumulations (tangles) of hyperphosphorylated tau, degeneration of the basal forebrain cholinergic pathway, and
Neurobehavioral approach uses behavioral paradigm towards comprehensive rehabilitation by identifying the neurological or neuropsychological constraints that can interfere with learning and behavior of an individual. The present case study highlights the role of functional skills approach in
Chronic hypoxia, viral infections/bacterial toxins, inflammation states, biochemical disorders, and genetic abnormalities are the most likely trigger of sudden infant death syndrome (SIDS). Autopsy studies have shown increased pulmonary density of macrophages and markedly more eosinophils in the
Evidence so far indicates that therapies targeting a single aspect of Alzheimer's disease (AD) have no sufficient efficacy in diminishing long-term the progression of AD. Neuroinflammation is an early event during the development of the disease and it is thought to exacerbate the abnormal
BACKGROUND
The pathological features in Alzheimer's disease (AD) brain include the accumulation and deposition of β-amyloid (Aβ), activation of astrocytes and microglia and disruption of cholinergic neurotransmission. Since the topographical characteristics of these different pathological processes
