Effect of Capsaicin on 3-NP-Induced Neurotoxicity: A Pre-Clinical Study.

The study objectives are to investigate the ability of capsaicin to revert the toxic effects in glutamate and lipopolysaccharide (LPS)-induced neurotoxicity in Neuro2a (N2a) cells as well as thwarting cognitive impairments, mitochondrial deficits, and oxidative insults induced by 3-nitropropanoic acid (3-NP) in a rodent model of Huntington's disease. In-vitro study with N2a cells was performed through MTT and LDH assay and their biochemical examinations were also performed. 3-NP-administered mice (n = 6) were treated with capsaicin (5, 10, and 20 mg/kg) through the per-oral (p.

Aim: To evaluate the potential beneficial role of Capsaicin in cognitive dysfunction, mitochondrial impairment, and oxidative damage induced by scopolamine in mice.

Background: Capsaicin is the chief phenolic component present in red chili and is responsible for its pungent and spicy flavor. It affects TRPV1 channels in nociceptive sensory neurons and is present in the hippocampus, and hypothalamus of the brains of rodents and humans.

Alternative Approaches for the Management of Huntington's Disease: A Narrative Review.

Huntington's disease (HD) is an autosomal neurodegenerative disease that involves movement disorders, cognitive impairments, and psychiatric symptoms. It is characterized by regionally selective cortical degeneration that proceeds from posterior to anterior cortical region which explains its heterogeneity. At present, the psychiatric symptoms of HD are mostly managed by antidepressant such as selective serotonin reuptake inhibitors or selective nor-epinephrine reuptake inhibitors, and atypical antipsychotics.

Potential of Capric Acid in Neurological Disorders: An Overview.

To solve the restrictions of a classical ketogenic diet, a modified medium-chain triglyceride diet was introduced which required only around 60% of dietary energy. Capric acid (CA), a small molecule, is one of the main components because its metabolic profile offers itself as an alternate source of energy to the brain in the form of ketone bodies. This is possible with the combined capability of CA to cross the blood-brain barrier and achieve a concentration of 50% concentration in the brain more than any other fatty acid in plasma.

Protective Role of Capsaicin in Neurological Disorders: An Overview.

Different pathological conditions that begin with slow and progressive deformations, cause irreversible affliction by producing loss of neurons and synapses. Commonly it is referred to as 'protein misfolding' diseases or proteinopathies and comprises the latest definition of neurological disorders (ND). Protein misfolding dynamics, proteasomal dysfunction, aggregation, defective degradation, oxidative stress, free radical formation, mitochondrial dysfunctions, impaired bioenergetics, DNA damage, neuronal Golgi apparatus fragmentation, axonal transport disruption, Neurotrophins (NTFs) dysfunction, neuroinflammatory or neuroimmune processes, and neurohumoral changes are the several mechanisms that embark the pathogenesis of ND.

Potential of Antibiotics for the Treatment and Management of Parkinson's Disease: An Overview.

Evidence has emerged over the last 2 decades to ascertain the proof of concepts viz. mitochondrial dysfunction, inflammation-derived oxidative damage and cytokine-induced toxicity that play a significant role in Parkinson's disease (PD). The available pharmacotherapies for PD are mainly symptomatic and typically indicate L-DOPA to restrain dopamine deficiency and its consequences.

Neurological manifestations and comorbidity associated with COVID-19: an overview.

First in 2002, severe acute respiratory syndrome coronavirus (SARS-CoV), second in 2012, Middle East respiratory syndrome coronavirus (MERS-CoV), and now the third in the December 2019, emergence of tremendously pathogenic and large-scale epidemic novel coronavirus (SARS-CoV-2) has brought the worst conditions into the human inhabitants of the twenty-first century. The SARS-CoV-2 uses the resembling receptor, angiotensin-converting enzyme 2 (ACE2) as that for SARS-CoV, and mainly feasts through the respiratory tract. The ACE2 receptor appearances have been also detected upon glial cells and neurons, which makes them a potential target of SARS-CoV-2 disease (COVID-19).

: antileishmanial efficacy & immumomodulatory activity.

Background & Objectives: The existing antileishmanial drugs for complete cure of visceral leishmaniasis (kala-azar) are limited. The available drugs are either toxic or less effective leading to disease relapse or conversion to post-kala-azar dermal leishmaniasis. Several herbal extracts have been shown to have antileishmanial activity, but a herbal drug may not always be safe.

Immunization with Leishmania donovani protein disulfide isomerase DNA construct induces Th1 and Th17 dependent immune response and protection against experimental visceral leishmaniasis in Balb/c mice.

In the present study, the efficacy of Leishmania donovani protein disulfide isomerase (LdPDI) as a DNA vaccine was evaluated in BALB/C mice. Mice immunized with the LdPDI-DNA construct were found to be the most immuno-reactive, as the construct induced higher T-cell proliferation. The increased T-cell proliferation was associated with a substantial rise in Th1 and Th17+ CD4 cell response and triggered a higher proportion of CD8+ T cells for the release of interferon-gamma along with a reduced splenic parasite load on Days20 and 60 post challenge (PC).

Beneficial effects of an Andrographis paniculata extract and andrographolide on cognitive functions in streptozotocin-induced diabetic rats.

Context Andrographolide containing Andrographis paniculata (Burm. F.) Wall.

Adaptogenic potential of andrographolide: An active principle of the king of bitters (Andrographis paniculata).

Andrographolide is a major bioactive secondary plant metabolite isolated Andrographis paniculata (Burm. F.) Wall.

Protective effects of Andrographis paniculata extract and pure andrographolide against chronic stress-triggered pathologies in rats.

This study was designed to experimentally verify the possibility that Andrographis paniculata could be another medicinal herb potentially useful for prevention of diverse spectrums of pathologies commonly associated with chronic unavoidable environmental stress, and whether andrographolide could as well be its quantitatively major bioactive secondary metabolite. Preventive effects of 21 daily oral 50, 100 and 200 mg/kg doses of a therapeutically used extract of the plant (AP) and 30 and 60 mg/kg/day of pure andrographolide were compared in rats subjected to 1-h daily unavoidable foot-shocks. A pharmaceutically well-standardized Withania somnifera (WS) root extract was used as a reference herbal anti-stress agent in all experiments.

Antidepressant-like effects of Brassica juncea L. leaves in diabetic rodents.

The objective of the study was to evaluate for antidepressant like activity of a methanolic extract of B. juncea leaves (BJ 100, 200, and 400 mg/kg/day, po), and Imipramine (15 mg/kg/day, po) in alloxan monohydrate (120 mg/kg, ip) induced diabetic and nondiabetic rodents, using behavioural despair, learned helplessness, and tail suspension tests for antidepressants and locomotor activity test for quantifying the behavioural effects of treatments. In addition, effects of BJ treatments on brain levels of norepinephrine, serotonin and dopamine were also estimated.

Unlabelled: CONTEXT. Brassica juncea (BJ; Linnaeus) Czern & Coss (Brassicaceae), commonly known as Indian mustard, are enriched in redox-active polyphenols with antidiabetic activities. Diverse other health benefits of this edible plant have been described in classical Ayurvedic texts.

Agar barrier method for removal of yeast and other fungal contamination from Leishmania promastigotes culture.

The present study explains a novel method of Leishmania promastigotes culture decontamination. The method is based on motility of Leishmania promastigotes across agar barrier which facilitates decontamination from yeast and other non motile contamination. This is inexpensive, easy, rapid and reliable physical method and is able to save valuable isolates in culture.
