Exosomes are small vesicles that form when multivesicular bodies fuse with the plasma membrane and are released into body fluids. They play a vital role in facilitating communication between cells by transferring different biomolecules, including DNA, RNA, proteins, and lipids, over both short and long distances. They also function as vital mediators in both states of health and disease, exerting an impact on several physiological processes.

Clustered Regions of Interspersed Palindromic Repeat (CRISPR)-based techniques have been utilized in various research areas, including agriculture, biotechnology, and medicine. With the use of a short sequence guide RNA and CRISPR-associated (Cas) protein, this technique allows for robust, site-specific manipulation of the genome, aiding researchers in making important biomedical discoveries and scientific advancements. In this review, we explored the applications of CRISPR/Cas systems in the field of parasitology for the identification and validation of novel functional genes, diagnosis of parasitic infections, reduction of parasite virulence, and the disruption of disease transmission.

Article Synopsis
  • The study aimed to evaluate the skin-lightening effects of Zerumbone (ZER) on human participants, noting a lack of prior clinical trials despite promising lab results.
  • Twenty-six participants used either ZER or a placebo cream on their forearms for four weeks, and skin irritation was monitored to ensure safety.
  • Results showed that ZER cream significantly reduced melanin levels after one week and continued to show effective results without any adverse effects.

The human gastrointestinal tract is populated with a diverse microbial community. The vast genetic and metabolic potential of the gut microbiome underpins its ubiquity in nearly every aspect of human biology, including health maintenance, development, aging, and disease. The advent of new sequencing technologies and culture-independent methods has allowed researchers to move beyond correlative studies toward mechanistic explorations to shed light on microbiome-host interactions.

Article Synopsis
  • Human umbilical cord mesenchymal stem cell-derived small extracellular vesicles (hUC-MSCs-sEVs) have shown potential in treating diabetes, but previous dosages used in animal studies were too high for human application.
  • This study evaluated the effects of lower doses of hUC-MSCs-sEVs on human skeletal muscle cells and type 2 diabetes mellitus (T2DM) rats, finding no significant cytotoxicity at 100 μg/mL and an 80-90% increase in glucose uptake at 20 μg/mL.
  • The treatment improved glucose tolerance and had protective effects on blood count, while also demonstrating no significant harm to liver and kidney functions, indicating that hUC-M

Since the commercialization of morphine in 1826, numerous alkaloids have been isolated and exploited effectively for the betterment of mankind, including cancer treatment. However, the commercialization of alkaloids as anticancer agents has generally been limited by serious side effects due to their lack of specificity to cancer cells, indiscriminate tissue distribution and toxic formulation excipients. Lipid-based nanoparticles represent the most effective drug delivery system concerning clinical translation owing to their unique, appealing characteristics for drug delivery.
