Collagen, a naturally occurring fibrous protein, is a potential resource of biological materials for tissue engineering and regenerative medicine because it is structurally biocompatible, has low immunogenicity, is biodegradable, and is biomimetic. Numerous studies have documented in the literature how Collagen nanofibers exhibit limited cell adhesion, poor viscosity, and no interior fibril structure. The biomedical industry is using Poly Glycerol Sebacate prepolymer(PGSp), a biodegradable and biocompatible polyester with high adhesion and very viscous appearance, more often.

The methylation pattern of non-imprinting genes was little studied, although it is widely known that the abnormal methylation levels of imprinting genes are associated with different forms of male infertility. The purpose of this research was to assess the CREM gene's methylation status and seminal characteristics in infertile individuals who were potential intracytoplasmic sperm injection (ICSI) candidates. A total of 45 semen samples (15 normospermia, 15 asthenospermia, and 15 oligoasthenoteratospermia) were examined.

Article Synopsis
  • Harmaline and green-synthesized silver nanoparticles were combined with folate-linked chitosan to create a drug delivery system aimed at targeting human ovarian and epithelioid cancer cells for pro-apoptotic and anti-metastatic effects.
  • The nanoparticles were characterized using various techniques, and their cytotoxicity was tested on cancer and normal cell lines, with results showing a selective impact on cancer cells.
  • The study concluded that the synthesized nanoparticles demonstrated significant cancer-selective cytotoxicity and anti-metastatic properties, indicating potential for future anticancer treatment applications.

Male infertility accounts for nearly 40%-50% of all infertile cases. One of the most prevalent disorders detected in infertile men is errors in the MEST differentially methylated region (DMR), which has been correlated with poor sperm indexes. The aim of our study was to characterize the methylation pattern of the MEST gene, along with assessing seminal factors and chromatin condensation in sperm samples from both infertile patients and fertile cases, all of whom were candidates for intracytoplasmic sperm injection.

One of the main health concerns of diabetes is testicular dysfunction and impairment of reproductive function and sperm quality which can cause male infertility. kisspeptin is a hypothalamic neuropeptide hormone that is involved in the regulation of energy metabolism, gonadotrophin-releasing hormone (GnRH), and reproductive function. In the present study, the therapeutic effects of empagliflozin (sodium-glucose co-transporter 2 inhibitors) on kisspeptin expression along with reproductive function were investigated in diabetic male Wistar rats.

Objective: Insulin insufficiency due to the reduced pancreatic beta cell number is the hallmark of diabetes, resulting in
an intense focus on the development of beta-cell replacement options. One approach to overcome the problem is to
search for alternative sources to induce insulin-producing cells (IPCs), the advent of mesenchymal stem cells (MSCs)
holds great promise for producing ample IPCs. Encapsulate the MSCs with alginate improved anti-inflammatory effects
of MSC treatment.

Amyloidosis is a heterogeneous group of protein deposition diseases associated with the presence of amyloid fibrils in tissues. Analogs of insulin that are used for treating diabetic patients (including regular insulin) can form amyloid fibrils, both in vitro and in vivo as reported in patients. The main purpose of this study was the induction of localized insulin-generated amyloidosis and the observation of effects on this process.

Diabetes is a serious public health problem in low- and middle-income countries. There is a strong link between hyperglycemia, oxidative stress, inflammation, and the development of diabetes mellitus. PI3K/Akt/mTOR is the main signaling pathway of insulin for controlling lipid and glucose metabolism.

The main purpose of neural tissue engineering and regenerative medicine is the development of biological substitutions to preserve, improve, and regenerate the damaged functions of tissues and organs. Three novel conduits, including polyurethane (PU), polyurethane/collagen (PU/C), and polyurethane/collagen/nano-bio glass (PU/C/NBG), were fabricated by the electrospinning technique. After confirming the suitability of conduits in the in-vitro environment, conduits were surgically sutured in a 10-mm gap in the sciatic nerve of a rat to evaluate their role in sciatic nerve reconstruction.
