The effect of redox bacteria on the programmed cell death-1 cancer immunotherapy.

Background And Purpose: Extracellular electron transferring (EET) or redox bacteria employ a shuttle of flavins to transfer electrons to the oxygen in the intestinal mucosa. Although clinical studies suggest that the gut microbiome modulates the efficiency of immune checkpoint therapy in patients with cancer, the modulation mechanisms have not been well-characterized yet.

Experimental Approach: In the present study, the oral gavage administration of MR-1 as a prototypic EET bacteria was assayed in a mouse model of lung cancer to determine the effect of EET bacterium on the efficacy of the programmed cell death protein 1 (PD1)-immune checkpoint therapy.

The microbiota-gut- hippocampus axis.

Introduction: It is well known that the intestinal bacteria substantially affect physiological processes in many body organs. Especially, through a bidirectional communication called as gut-microbiota-brain axis, the gut microbiota deeply influences development and function of the nervous system. Hippocampus, as a part of medial temporal lobe, is known to be involved in cognition, emotion, and anxiety.

Protective effects of nanocurcumin against stress-induced deterioration in the intestine.

The therapeutic activities of curcumin have long been investigated in some chronic and inflammatory diseases. This study was designed to investigate the protective effects of nanocurcumin on intestinal barrier function, apoptosis, and oxidative stress in rats exposed to traffic noise. Forty rats were divided into four groups: two traffic noise-exposed groups of animals that received either vehicle (NOISE) or nanocurcumin (NCUR + NOISE) and two control groups that either remained intact (CON) or received nanocurcumin (NCUR).

Good bacteria, oxidative stress and neurological disorders: Possible therapeutical considerations.

Although oxidative agents such as free radicals can fight pathogens, an imbalance of oxidant/anti-oxidant activity can lead to harmful effects in our body known as oxidative stress. Various cellular organelles produce oxidative agents as well as anti-oxidants. The main oxidative stressors are classified under the free radical species; reactive oxygen species and reactive nitrogen species.

Effects of nano-curcumin on noise stress-induced hippocampus-dependent memory impairment: behavioral and electrophysiological aspects.

Background: Noise pollution is one of the fundamental factors in the etiology of many disorders. Noise stress adversely affects cognitive behaviors and long-term potentiation (LTP), the candidate mechanism of learning and memory. In the present study, we examined the neuroprotective effects of nano-curcumin on behavioral and electrophysiological aspects of hippocampus-dependent memory in noise-exposed animals.

Alzheimer's disease treatment: The share of herbal medicines.

One of the most frequent forms of dementia in neurological disorders is Alzheimer's disease (AD). It is a chronic neurodegenerative disease characterized by impaired learning and memory. Pathological symptoms as extracellular amyloid-beta (Aβ) plaques and intracellular accumulation of neurofibrillary tangles occur in AD.

Probiotic treatment differentially affects the behavioral and electrophysiological aspects in ethanol exposed animals.

Objectives: Harmful effects of alcohol on brain function including cognitive phenomena are well known. Damage to gut microbiota is linked to neurological disorders. Evidence indicates that intestinal flora can be strengthened by probiotic bacteria.

Corrigendum: Does Severity of Alzheimer's Disease Contribute to Its Responsiveness to Modifying Gut Microbiota? A Double Blind Clinical Trial.

Lavandula angustifolia biological characteristics: An in vitro study.

Objective: Lavender is an aromatic shrub belonging to the Lamiaceae family. The flowers and leaves in different forms of extracts are used as herbal medicine. The accumulation of amyloid beta (Aβ) plaques, reduction of acetylcholine due to hyperactivity of acetylcholinesterase, and glutamate neurotoxicity are known to be involved in decreased level of cognitive function.

Does Severity of Alzheimer's Disease Contribute to Its Responsiveness to Modifying Gut Microbiota? A Double Blind Clinical Trial.

Alzheimer's disease (AD) is associated with cognitive dysfunction. Evidence indicates that gut microbiota is altered in the AD and, hence, modifying the gut flora may affect the disease. In the previous clinical research we evaluated the effect of a probiotic combination on the cognitive abilities of AD patients.

Lavandula angustifolia extract improves deteriorated synaptic plasticity in an animal model of Alzheimer's disease.

Objectives: Neurodegenerative Alzheimer's disease (AD) is associated with profound deficits in synaptic transmission and synaptic plasticity. Long-term potentiation (LTP), an experimental form of synaptic plasticity, is intensively examined in hippocampus. In this study we evaluated the effect of aqueous extract of lavender (Lavandula angustifolia) on induction of LTP in the CA1 area of hippocampus.
