The length of the menstrual cycle (MC) varies among women, with an average regularity between 21 and 40 days. Six temporal frames can be observed within the monthly cycle, based on the fluctuations of the hormone levels. These fluctuations are accompanied by alterations in the central nervous system (CNS) and autonomic nervous system (ANS) and can be quantified using psychophysiological techniques. In this systematic review, we discussed the studies conducted with healthy females that examined aspects associated wi [...]

Preparations of Zingiber officinale are used in Nigerian folk medicine to manage colds, pain, arthritis, nausea, and epilepsy. The ameliorative effects of co-administering aqueous Zingiber officinale extract (GE) and sodium valproate (SDV) on pentylenetetrazole-kindled mice were evaluated regarding cognitive deficits, neuronal cell loss, and seizure severity. GFAP was also quantified. Male mice were pretreated with GE (50 mg/kg), SDV (100 and 200 mg/kg), and GE + SDV before kindling. After kindling, the mice underw [...]

COVID-19 greatly affected the lives of adolescents through restrictions such as less playtime, more screen time, and limited interaction with peers. In this study, we assessed the impact of the COVID-19 pandemic on the dietary and physical activity-related behavior of school students aged 10–16 years. This cross-sectional study was conducted with adolescents recruited from seven randomly selected private schools in Delhi, India, during 2021. A self-administered web-based survey was conducted to evaluate the behavio [...]

We fabricated three thermo-rechargeable batteries using low-cost transition metal hexacyanoferrate and determined the thermal voltage (Vcell) and discharge capacity (Qcell) per unit weight of the total active material in the cathode and anode. The obtained values were compared with the calculated values, which were determined by analyzing the temperature and capacity coefficients of the redox potential.

Cerebrovascular atherosclerosis, and several other cardiovascular (or "inflamm-aging" type) diseases, are more frequent and advanced in subjects with Alzheimer's disease compared with normal aging. In addition, the observed pathogenic link to dementia (and its associated cerebral microvascular damage) is readily explained by alterations of arterial elasticity. A therapeutic strategy to delay dementia could be based upon localized drug delivery, using lipid nanocarriers (i.e., biobased nanoemulsion technology), targ [...]

Herein, we report the coating of nanostructured germanium using a polypyrrole (PPy) polymer coat as a composite anode material for the fabrication of lithium-ion batteries. The Ge/PPy composites were synthesized following the direct electrochemical deposition method in an ionic liquid (IL). The results revealed that the coating of PPy on Ge helped realize stable battery cycling and reversible capacities, which were not observed in uncoated Ge. The PPy layers could effectively inhibit side reactions between the elec [...]

Glaucomatous optic neuropathy (GON) associated with different forms of glaucoma and chronic ocular hypertension (cOHT) is characterized by progressive loss of retinal ganglion cells and their axons in the optic nerves that project to the brain to transmit visual information. The resultant thinning of the optic nerves cause loss of peripheral vision, which if not halted or slowed, can lead to irreversible blindness. Whilst the precise triggering insult(s) for the primary open angle glaucoma (POAG), the most prevalen [...]

Maize is consumed as a food and used as an industrial product in the form of starch, pharmaceuticals, alcoholic beverages, oil, cosmetics, and textiles. In ancient times, landraces were more popular due to the presence of high genetic variability, resistance to biotic and abiotic factors, and the heterogeneous nature of maize; however, it has been replaced by improved and uniform cultivars with a higher yield. Modern maize has more homogeneity that enhances its vulnerability to biotic and abiotic stresses. Thus, we [...]

Photobiomodulation therapy (PBMT) for minimal to moderate Kellgren and Lawrence grade knee osteoarthritis has significant evidence for effectiveness. The effect of PBMT in severe grades of osteoarthritis is less clear; and no studies have investigated the effect of PBMT before and after knee replacement surgery. This small study (n=4) aimed to understand the potential feasibility of undertaking a future randomised controlled clinical trial of a self-administered, home-based light patch system before and after total [...]

Cyanobacteria are the most ancient phytoplankton that first appeared at least 2.5 billion years ago and have a prolonged evolutionary history. They can form impenetrable and toxic blooms in aquatic ecosystems such as freshwater and marine environments. Cyanobacterial blooms produce cyanotoxins that endanger ecosystem functioning and deteriorate water quality used for recreation, drinking, and in fisheries, thus, adversely affecting human health and the economy. Some bloom-producing genera are Aphanizomenon, Plankto [...]
