Neurodegenerative disorders (NDDs) have been prevalent for more than a decade, and the number of individuals affected per year has increased exponentially. Among these NDDs, Alzheimer's disease, which causes extreme cognitive impairment, and Parkinson's disease, characterized by impairments in motor activity, are the most prevalent. While few treatments are available for clinical practice, they have minimal effects on reversing the neurodegeneration associated with these debilitating diseases.

The microbiota-gut-brain axis is a pivotal medium of crosstalk between the central nervous system (CNS) and the gastrointestinal tract. It is an intricate network of synergistic molecular pathways that exert their effects far beyond their local vicinity and even affect the systemic functioning of the body. The current review explores the involvement of the gut-brain axis (GBA) in the functioning of the nervous system, with a special emphasis on the neurodegeneration, cognitive decline, and neuroinflammation that occur in Alzheimer's disease (AD) and Parkinson's disease (PD).

Caloric restriction mimetics mimic the beneficial effects of dietary restriction approaches, such as caloric restriction approaches, without limiting the dietary intake. Chlorogenic acid (CGA) acts as a caloric restriction mimetic; however, its neuroprotective mechanisms remain ambiguous. Therefore, in this study, we aimed to elucidate the neuroprotective effects of CGA on SH-SY5Y cells treated with amyloid-beta (Aβ)1-42.

Aging, an inevitable physiological process leading to a progressive decline in bodily functions, has been an abundantly researched domain with studies attempting to slow it down and reduce its debilitating effects. Investigations into the cellular and molecular pathways associated with aging have allowed the formulation of therapeutic strategies. Of these, caloric restriction (CR) has been implicated for its role in promoting healthy aging by modulating key molecular targets like Insulin/IGF-1, mTOR, and sirtuins.

Article Synopsis
  • - The study investigates how microwave treatment affects the phytochemical content, antioxidant properties, and anti-nutritional factors of de-oiled rice bran, with results varying based on wattage and duration of treatment.
  • - Total phenolics and flavonoids showed mixed results depending on microwave settings, while flavonol content consistently increased; some antioxidant activities improved with microwaving, but overexposure at high power decreased these benefits.
  • - Metabolomics analysis revealed variations in specific metabolites after treatment, suggesting that tailored microwaving can enhance beneficial compounds in de-oiled rice bran without significantly affecting overall metabolite levels.

Background: Antenatal hydronephrosis (ANH) is a common prenatal finding that requires careful evaluation to determine appropriate management strategies. The variability in outcomes underscores the need for refined diagnostic and monitoring protocols to differentiate between cases necessitating intervention and those likely to resolve spontaneously.

Materials And Methods: A prospective clinical study was conducted involving 150 pregnant women diagnosed with ANH between gestational weeks 18 to 24.

This study aims to investigate the physical stability, droplet size, zeta potential, and antimicrobial properties of nanoemulsions formulated with betel leaf extract using β-cyclodextrin (CD) and sodium alginate (SA) biopolymers. Nanoemulsions with β-cyclodextrin exhibit superior stability at lower temperatures, with limited droplet size, and strong electrostatic repulsion. Morphological images demonstrate the successful encapsulation of betel leaf extract within both biopolymers, highlighting their potential for antimicrobial applications.

Article Synopsis
  • - The study focuses on the thermal conductivity of β-GaO, emphasizing its significance for high-voltage and high-temperature uses, while highlighting unresolved discrepancies in calculated values along different crystal directions.
  • - It finds that understanding chemical bonding is key to resolving these discrepancies, especially in low-symmetry structures like β-GaO, which require large supercells to accurately capture a variety of bonding interactions.
  • - The research reveals that modeling bonding characteristics leads to better estimation of acoustic and optical contributions to thermal conductivity and shows that third-order interaction terms are sufficient for accurate calculations, aligning well with experimental data.

The gut microbiota (GM) produces various molecules that regulate the physiological functionality of the brain through the gut-brain axis (GBA). Studies suggest that alteration in GBA may lead to the onset and progression of various neurological dysfunctions. Moreover, aging is one of the prominent causes that contribute to the alteration of GBA.

We read with great interest the article "the deadly duo of hypertension and diabetes in India: further affirmation from a new epidemiological study" by Metri et al. They rightly pointed out that the prevalence of hypertension in Indian patients with type 2 diabetes patients is high and therefore early screening and management of hypertension should be included in the treatment of patients with type 2 diabetes. We wish to share our study findings on the prevalence of hypertension in newly onset diabetes mellitus (DM).

has been demonstrated to be an excellent platform for the multi-fragment assembly of large DNA constructs through its powerful homologous recombination ability. These assemblies have invariably used the stable centromeric single copy vectors. However, many applications of these assembled genomes would benefit from assembly in a higher copy number vector for improved downstream extraction of intact genomes from the yeast.

Article Synopsis
  • The study presents a new type of ammonia (NH) sensor made with nickel-doped cerium oxide (Ni-doped CeO), capable of detecting NH concentrations as low as 45 parts per billion (ppb) at room temperature.
  • It shows a significantly enhanced response (42) towards higher concentrations (225 ppm) compared to pure CeO, achieving performance improvements through the creation of oxygen vacancies and changes in bandgap and redox properties due to the doping.
  • The findings support the idea that engineering defects, like incorporating Ni into the CeO structure, can improve sensor capabilities, making this research valuable for developing advanced air quality monitoring technologies.

Psychedelics have traditionally been used for spiritual and recreational purposes, but recent developments in psychotherapy have highlighted their potential as therapeutic agents. These compounds, which act as potent 5-hydroxytryptamine (5HT) agonists, have been recognized for their ability to enhance neural plasticity through the activation of the serotoninergic and glutamatergic systems. However, the implications of these findings for the treatment of neurodegenerative disorders, particularly dementia, have not been fully explored.
