Summary: This study aims to investigate the mechanisms of the protective effect against hypoxic-ischemic brain damage (HIBD) of mfat-1 transgenic mice. The results showed that mfat-1 transgenic mice not only exhibited improved neurological function and reduced neuronal damage after HIBD, but also maintained the physiological permeability of the blood-brain barrier (BBB). It was found that the protective effect of mfat-1 transgenic mice was associated with increased expression of major facilitator superfamily domain-containing 2a (Mfsd2a) on the BBB.

Summary: The use of nanomaterials in polymeric composite membranes has the potential to improve separation performance. However, the dispersion and stability of these nanomaterials have been major issues for commercial applications. In this study, zinc oxide powders were blended into polyvinyl chloride ultrafiltration membranes, resulting in improved membrane microstructure, separation performance, and bulk properties. The membranes with 0.05% weight MicNo (R) platelets had higher water flux and enhanced antifouling properties compared to pristine PVC and commercial ZnO-doped membranes.

Summary: The causative agent of Covid-19 is a new type of coronavirus called SARS-CoV-2, which severely affects the respiratory tract. Efforts have been made to test different drugs and agents for treatment, but their use has been associated with adverse events. The emergence of SARS-CoV-2 variants has raised the need for effective and safe agents to combat the infection, even in vaccinated individuals. Obeticholic acid (OCA), with its anti-inflammatory effects, may be a potential treatment for Covid-19. This perspective study focuses on the possible medicinal effectiveness of OCA in managing the disease.

Summary: The anti-inflammatory potential of Penicillium brefeldianum endophytic fungus was investigated in carrageenan-induced inflammation in rats. The results showed that the fungus-treated group (200 mg/kg) had a significant decrease in edema weight, fewer inflammatory cells, and thickened epidermis. Immunostaining and qRT-PCR analysis both demonstrated a decrease in immune cells and interleukin gene expression in the fungus-treated group. Additionally, the levels of inflammatory and oxidative stress markers were considerably diminished in this group. These findings suggest that P. brefeldianum endophytic fungus has promising anti-inflammatory properties.

Summary: This study investigated the allelopathic properties of alfalfa seedling exudates on seed germination and identified the compounds responsible by using liquid chromatography ion mobility high-resolution mass spectrometry. Crude exudates inhibited the germination of all tested plant species. Nine compounds, including a flavonoid glucoside, a non-proteinogenic amino acid, and two dipeptides, were identified in alfalfa. The antibacterial and antibiofilm activities of the exudate and its compounds were also explored.

Summary: Parkinson's disease (PD) is caused by the degeneration of dopaminergic neurons in the substantia nigra (SN) and current management options focus on symptom relief. However, there is a need for novel treatments that can effectively manage both motor and non-motor symptoms of PD. Dipeptidyl peptidase 4 (DPP-4) inhibitors have shown promising results in protecting against PD. This study aims to uncover the mechanism of DPP-4 inhibitors in managing PD.

Summary: This study evaluated the topical effect of Lepidium sativum lyophilized seed extract (LSLE) in treating Sustanon-induced alopecia in rats. LSLE treated group showed changes in alopecia biomarkers, androgenic markers, testosterone level, and 5 alpha-reductase. On the other hand, LSLE treated group showed improvement in vascular markers. LC-MS/MS analysis identified 17 constituents in LSLE. The study suggests the potential role of LSLE in treating alopecia by decreasing 5(alpha)-dihydrotestosterone levels.

Summary: This study isolated chlorogenic acid (CGA) from Euphorbia milii flowers and prepared CGA nanoparticles using the electrospraying technique in a polyvinyl alcohol (PVA)/poly(lactic-co-glycolic acid) (PLGA) polymeric matrix. The optimized formula (F2) exhibited significant antibacterial activity against Pseudomonas aeruginosa and antiviral activity against HCoV-229E and MERS-CoV. The encapsulation of CGA into electrospray PVA/PLGA nanoparticles shows promise as an antimicrobial agent.

Summary: In this study, the anti-Alzheimer's potential of Abelmoschus esculentus (okra) was evaluated through in vitro and in vivo experiments. The results showed significant anti-Alzheimer's activity of the total seed extract, as confirmed by DPPH free radical assay and AChE inhibition potential screening. In vivo experiments also demonstrated the improvement in Alzheimer's rats, with restored levels of various biomarkers and histological findings of brain tissue. Network pharmacology analysis further revealed the relation between identified compounds in okra and genes associated with Alzheimer's disorders.

Summary: Currently, antimicrobial resistance is spreading at an accelerated rate, leading researchers to investigate alternative treatments. This study evaluated the antibacterial properties of zinc-oxide nanoparticles synthesized from Cycas circinalis against Proteus mirabilis clinical isolates. The nanoparticles were found to be effective in inhibiting bacterial growth in vitro and in vivo, reducing bacterial count and improving survival rates in a mouse model. The study suggests that zinc-oxide nanoparticles could be a potential solution to bacterial infections caused by Proteus mirabilis.
