Medicinal herbs used in traditional diabetes treatment are a rich source of anti-diabetic compounds. Pancreatic α-amylase inhibitors offer an effective strategy to reduce postprandial hyperglycemic levels via control of starch degradation. In this context, our study for the first time investigates the effect of stamens extracts on α-amylase inhibition.

Article Synopsis
  • Varicocele, caused by dilated testicular veins, is a surgically correctable factor linked to male infertility, especially in men with severe oligoasthenoteratozoospermia (OAT).
  • A study involving 360 men demonstrated that varicocelectomy significantly improved sperm concentration, motility, morphology, and total motile sperm count (TMSC) at 6, 12, and 18 months post-surgery.
  • The procedure also led to a reduction in sperm DNA fragmentation, indicating better overall sperm quality and suggesting the potential for improved fertility outcomes.

Objective: Recently, oral antioxidants in combined forms have been used to treat men with idiopathic infertility. This study aimed to evaluate the effects of treatment with vitamin C, vitamin E, selenium, zinc, arginine, L-carnitine, and coenzyme Q10 on sperm quality parameters, DNA integrity, reproductive hormones, and pregnancy rates in men with infertility and idiopathic oligoasthenoteratozoospermia (OAT).

Methods: A prospective study was conducted on 420 men with infertility and idiopathic OAT who took an oral supplement of antioxidant SP-Power tablets twice daily for 6 months.

Four mononuclear complexes (HO){[NiL](ClO)} (), [CoL](ClO)·2HO (), [CdLCl] () and [CuL](NO) () have been prepared employing a newly synthesized 1,2,4-triazole ligand: 3-(3,5-dimethyl-1-pyrazol-1-yl)-1-1,2,4-triazole (). The structures of the complexes, which crystallized in (), (), (), and (), are reviewed within the context of the cooperative effect of the hydrogen bonding network and counter anions on the supramolecular formations. Moreover, within the framework of biological activity examination, these compounds showed favorable antibacterial performances compared to those of various species of bacteria, including both Gram-positive and Gram-negative strains.

Article Synopsis
  • Azoospermia affects 10-15% of infertile men, with a study in Morocco exploring its clinical, hormonal, and genetic aspects among 80 patients.
  • Most participants (96%) experienced primary infertility, with a majority of azoospermia cases being of excretory origin and linked to conditions like hydrocele.
  • The study revealed specific hormonal levels, a high prevalence of chromosomal abnormalities (30.7%), and microdeletion rates, highlighting important factors contributing to male infertility in Morocco.

A new pyrazole ligand, ,-bis(2(1',5,5'-trimethyl-1,1'-[3,3'-bipyrazol]-1-yl)ethyl)propan-1-amine (L) was synthesized and characterized by H-NMR, C-NMR, FT-IR and HRMS. The coordination ability of the ligand has been employed for the construction of a new family of coordination complexes, namely: [CuLCl] (1), [ML(CHOH)(HO)](ClO) (M = Ni (2), Co (3)) and [FeL(NCS)] (4). The series of complexes were characterized using single-crystal X-ray diffraction, HRMS, FT-IR and UV-visible spectroscopy.
