Neuronal plasticity and its role in Alzheimer's disease and Parkinson's disease.

Neuronal plasticity, the brain's ability to adapt structurally and functionally, Is essential for learning, memory, and recovery from injuries. In neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease, this plasticity is disrupted, leading to cognitive and motor deficits. This review explores the mechanisms of neuronal plasticity and its effect on Alzheimer's disease and Parkinson's disease.

A potential toxicological risk assessment of heavy metals and pesticides in irrigated rice cultivars near industrial areas of Dhaka, Bangladesh.

Rice intake represents a significant pathway through which humans accumulate heavy metals. This study presents a comprehensive analysis of heavy metal and pesticide contamination in rice cultivars irrigated with industrial wastewater near Dhaka, Bangladesh, a region heavily influenced by industrial activities. This study employed a unique methodology that not only quantified the concentrations of heavy metals and pesticide residues in rice grains but also extended to evaluating the physicochemical properties of rice stems, husks, soil, and irrigation water.

Bio-Inspired Nanomaterials for Micro/Nanodevices: A New Era in Biomedical Applications.

Exploring bio-inspired nanomaterials (BINMs) and incorporating them into micro/nanodevices represent a significant development in biomedical applications. Nanomaterials, engineered to imitate biological structures and processes, exhibit distinctive attributes such as exceptional biocompatibility, multifunctionality, and unparalleled versatility. The utilization of BINMs demonstrates significant potential in diverse domains of biomedical micro/nanodevices, encompassing biosensors, targeted drug delivery systems, and advanced tissue engineering constructs.

Effect of sizes of vinyl modified narrow-dispersed silica cross-linker on the mechanical properties of acrylamide based hydrogel.

Polymeric hydrogel with the incorporation of nano to submicro-meter sized materials forms an exhilarating new generation of composite hydrogels. Most of the applications of hydrogels are in aqueous environments in which they swell to a very high degree. This emanates from low density of the polymer chains, making them highly inferior in terms of physical strength and their prospective applications.

Green Polymer Nanocomposites in Automotive and Packaging Industries.

Green polymer nanocomposites referred to as completely biodegradable, renewable, environmentally friendly, and benign materials, have received a surge of attention to promote sustainable development. Polymer nanocomposites, where nanomaterials are used for reinforcement, possess a large interfacial area per volume, and the intervals between the filler nanoparticles and polymer matrix are significantly short. Molecular interactions between the filler particles and the matrix, therefore, provide polymer nanocomposites with novel characteristics that ordinary polymers or conventional macrocomposites do not possess.

Rapid diagnosis of COVID-19 nano-biosensor-implemented biomedical utilization: a systematic review.

The novel human coronavirus pandemic is one of the most significant occurrences in human civilization. The rapid proliferation and mutation of Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) have created an exceedingly challenging situation throughout the world's healthcare systems ranging from underdeveloped countries to super-developed countries. The disease is generally recognized as coronavirus disease 2019 (COVID-19), and it is caused by a new human CoV, which has put mankind in jeopardy.

Far lateral approach: Is condylar resection required?

Background: We report our experience with the far lateral approach (FLA) and its modifications in the surgical resection of tumors of craniocervical junction (CCJ).

Materials And Methodology: We retrospectively reviewed data of 36 patients with CCJ lesions who underwent surgical excision. Data are presented as frequency/percentages.

Structurally coloured secondary particles composed of black and white colloidal particles.

This study investigated the colourful secondary particles formed by controlling the aggregation states of colloidal silica particles and the enhancement of the structural colouration of the secondary particles caused by adding black particles. We obtained glossy, partially structurally coloured secondary particles in the absence of NaCl, but matte, whitish secondary particles were obtained in the presence of NaCl. When a small amount of carbon black was incorporated into both types of secondary particles, the incoherent multiple scattering of light from the amorphous region was considerably reduced.

Structural colored gels for tunable soft photonic crystals.

A periodically ordered interconnecting porous structure can be embodied in chemical gels by using closest-packed colloidal crystals as templates. The interconnecting porosity not only provides a quick response but also endows the porous gels with structural color arising from coherent Bragg optical diffraction. The structural colors revealed by porous gels can be regulated by several techniques, and thus, it is feasible to obtain desirable, smart, soft materials.
