A combination of gliclazide and metformin attenuates obesity-induced polycystic ovary syndrome in female Wistar rats.

Presently, it is known that the progression of obesity concomitantly leads to polycystic ovary syndrome and infertility. This study aimed to evaluate the potential effects of metformin (M; insulin secretagogues) and gliclazide (G; insulin sensitizer) alone and their combination at different doses to treat obesity-induced PCOS. High high-fat diet was given to all female Wistar rats for nine weeks to induce obesity except for the normal control group which received a normal chow diet.

Development of biomedical hydrogels for rheumatoid arthritis treatment.

Rheumatoid Arthritis (RA) is an autoimmune disorder that hinders the normal functioning of bones and joints and reduces the quality of human life. Every year, millions of people are diagnosed with RA worldwide, particularly among elderly individuals and women. Therefore, there is a global need to develop new biomaterials, medicines and therapeutic methods for treating RA.

Development of mRNA nano-vaccines for COVID-19 prevention and its biochemical interactions with various disease conditions and age groups.

This review has focused on the development of mRNA nano-vaccine and the biochemical interactions of anti-COVID-19 mRNA vaccines with various disease conditions and age groups. It studied five major groups of individuals with different disease conditions and ages, including allergic background, infarction background, adolescent, and adult (youngsters), pregnant women, and elderly. All five groups had been reported to have background-related adverse effects.

Micro- and nanoplastics: Contamination routes of food products and critical interpretation of detection strategies.

Micro-and nanoplastics (M/NPs) are emerging pollutants released into the food, beverages, and environment from plastic products by weathering, oxidative damage, and mechanical stress. Detection of M/NPs in food and beverages is a vital factor in preventing the deleterious effects of these materials on human health and other ecosystems. Analytical strategies for M/NPs demonstrate numerous drawbacks, including detection sensitivity limitation, matrix digestion, and sample pretreatment.

Exploring the robustness of DNA nanotubes framework for anticancer theranostics toward the 2D/3D clusters of hypopharyngeal respiratory tumor cells.

This study aimed to develop a robust approach for the early diagnosis and treatment of tumors. Short circular DNA nanotechnology synthesized a stiff and compact DNA nanotubes (DNA-NTs) framework. TW-37, a small molecular drug, was loaded into DNA-NTs for BH3-mimetic therapy to elevate the intracellular cytochrome-c levels in 2D/3D hypopharyngeal tumor (FaDu) cell clusters.

Topical lycopene emulgel significantly improves biophysical parameters of human skin.

Carotenoids, including lycopene, are promising antioxidants that sequester free radicals and counterbalance oxidative stress, preventing cardiovascular diseases, cancer, photo-damage, and decelerating aging. Fabricating the antioxidant effective and stable topical formulations with efficient skin penetration and preserving their activity by minimizing the oxidative damage due to ionization, pH extremes, high storage temperature, and metal ions, has been challenging. Herein, we developed a lycopene-based topical emulgel and investigated its impact on biophysical parameters of human skin using non-invasive in vivo techniques and sensory evaluation for consumer acceptability to bottleneck the demerits of conventional formulations.

Hepatoprotective effect of Cordia rothii extract against CCl-induced oxidative stress via Nrf2-NFκB pathways.

Cordia rothii Roem. & Schult. possesses various beneficial effects and is traditionally used in folk medicine against liver diseases but its molecular mechanism remains unclear.

Disrupting biofilm and eradicating bacteria by Ag-FeO@MoS MNPs nanocomposite carrying enzyme and antibiotics.

In this study, novel multilayered magnetic nanoparticles (ML-MNPs) loaded with DNase and/or vancomycin (Vanc) were fabricated for eliminating multispecies biofilms. Iron-oxide MNPs (IO-core) (500-800 nm) were synthesized via co-precipitation; further, the IO-core was coated with heavy-metal-based layers (Ag and MoS NPs) using solvent evaporation. DNase and Vanc were loaded onto the outermost layer of the ML-MNP formed by nanoporous MoS NPs through physical deposition and adsorption.

Nanoscale packing of DNA tiles into DNA macromolecular lattices.

Nanoscale double-crossovers (DX), antiparallel (A), and even half-turns-perimeter (E) DNA tiles (DAE-tiles) with rectangular shapes can be packed into large arrays of micrometer-scale lattices. But the features and mechanical strength of DNA assembly made from differently shaped large-sized DAE DNA tiles and the effects of various geometries on the final DNA assembly are yet to be explored. Herein, we focused on examining DNA lattices synthesized from DX bi-triangular, DNA tiles (T) with concave and convex regions along the perimeter of the tiles.

Nanostructured Lipid Carrier-Based Delivery of Pioglitazone for Treatment of Type 2 Diabetes.

Pioglitazone (PGZ) is utilized as a therapeutic agent in the management of (type 2) diabetes to control blood glucose levels. The existing research work was intended to make and optimize PGZ-containing NLCs (nanostructured lipid carriers). The fabricated nanostructured lipid carrier preparation was optimized by using different concentrations of the surfactants (Tween 80 and Span 80) and solid lipid (Compritol 888 ATO) and liquid lipid (Labrasol) while keeping the concentration of drug (PGZ), and co-surfactants (poloxamer 188) the same.

Application Perspectives of Nanomedicine in Cancer Treatment.

Cancer is a disease that seriously threatens human health. Based on the improvement of traditional treatment methods and the development of new treatment modes, the pattern of cancer treatment is constantly being optimized. Nanomedicine plays an important role in these evolving tumor treatment modalities.

Controlled release floating drug delivery system for proton pump inhibitors lansoprazole: In-vitro, In-vivo floating and pharmacokinetic evaluation.

Lansoprazole (LPZ) show poor bioavailability because of first pass effect and absorption factors. The floating delivery systems could reduce fluctuations in plasma drug concentration through maintaining desirable plasma drug concentration. The objective of present study was to enhance bioavailability despite first pass effect through continuous availability of drug from floating system.

2D DNA lattices assembled from DX-coupled tiles.

Hypothesis: Formation of coupled double crossovers (DXs) in a circular 106-mer oligonucleotide (c106nt) could generate stable tiles with the tile core span of 10 half turns. The large-span tiles with complicated curvatures and mechanics could assemble 2D lattices under different environments. Hence, 2D DNA lattice structures based on tile types and sequences, tile packing modes of corrugation and non-corrugation, and assembly media of solution and the substrate-solution interface are yet to be explored.

Therapeutic interventions to urologic chronic pelvic pain syndrome and UPOINT system for clinical phenotyping: How far are we?

The assessment and management of urologic chronic pelvic pain syndrome (UCPPS), is controversial. It is classified by voiding symptoms, pelvic pain, and bladder pain, which is weekly treated, weekly understood, and bothersome. In the aspect of clinical efforts and research to help people with this syndrome have been hampered by the deficiency of a widely reliable, accepted, and a valuable tool to evaluate the patient symptoms and quality of life (QoL) impact.

2D DNA nanoporous scaffold promotes osteogenic differentiation of pre-osteoblasts.

Biofunctional materials with nanomechanical parameters similar to bone tissue may promote the adherence, migration, proliferation, and differentiation of pre-osteoblasts. In this study, deoxyribonucleic acid (DNA) nanoporous scaffold (DNA-NPS) was synthesized by the polymerization of rectangular and double-crossover (DX) DNA tiles. The diagonally precise polymerization of nanometer-sized DNA tiles (A + B) through sticky end cohesion gave rise to a micrometer-sized porous giant-sheet material.
