Perichondrial telocytes (TCs) play a pivotal role in cartilage development, as demonstrated by their expression of CD34, CD117, VEGF, MMP-9, CD21, and CD68. These markers highlight their involvement in angiogenesis, extracellular matrix (ECM) remodeling, immune modulation, and tissue homeostasis. VEGF expression suggests a role in promoting vascularization, while MMP-9 indicates their contribution to ECM remodeling.

The heart of date palm powder serves as a valuable source of various biological macromolecules, such as dietary fibers and proteins, which contribute to its benefits as a health-enhancing ingredient. The main component of the heart date palm is carbohydrates, which provide a rapid energy source and its fiber content aids digestion and promotes feelings of fullness, thereby enhancing any diet. This research studied the possibility of incorporating the heart of date palm powder at varying concentrations (0, 3 %, 6 %, 9 %, and 12 % w/v) into low-fat bio Labneh made from a mix of camel and corn milk (75 %: 25 %).

Inhibition of the adenosine 2A receptor (AR) is recognized as a promising immunotherapeutic strategy but is challenged by the ubiquity of AR function in the immune system. To develop a safe yet efficacious immunotherapy, the discovery of a novel negative allosteric modulator (NAM) was preferred. Leveraging an in-house, sensitive, high-throughput screening cellular assay, novel AR NAM scaffolds were identified, followed by an extensive structure-activity relationship (SAR) study, leading to the discovery of potent 2-amino-3,5-dicyanopyridine derivatives.

Traditional electrospinning is a promising technique for fabricating nanofibers for tissue engineering and drug delivery applications. The method is highly efficient in producing nanofibers with morphology and porosity similar to the extracellular matrix. Nonetheless, and in many instances, the process has faced several limitations, including weak mechanical strength, large diameter distributions, and scaling-up difficulties of its fabricated electrospun nanofibers.

NADPH oxidase (NOX) has been identified as a crucial contender of oxidative damage in Alzheimer's disease (AD). However, the capability of diapocynin, a NOX inhibitor, to offer neuroprotection in AD models is still a matter of debate. Hence, the current work is dedicated to investigate the influence of diapocynin on cognitive impairment prompted by ovariectomy combined with D-galactose injection in rats (an AD animal model), and to elucidate the signaling mechanisms regulating diapocynin-induced effects.
