Insights into the photoactivatable CO releasing properties of dicarbonyl Ru(II) complex with 8-amino quinoline ligand: Experimental and theoretical studies.

Reaction between the polymeric [RuCl(CO)] and the N,N-bidentate ligand, 8-amino-quinoline (Quin), in methanol, afforded the photoactivated CO releasing molecule with the formula of trans-(Cl,Cl)-[RuCl(CO)Quin]. In the presence of biomolecules or in solvents with varying polarity and coordinating abilities, the solvatochromic characteristics and dark stability were investigated. A new board band emerged in the visible spectrum during the illumination, and its position varies according to the type of solvent used, indicating the role of the solvent in controlling the nature of the CO-depleted species.

Chromosomal abnormalities in infertile men with azoospermia and severe oligozoospermia in Qatar and their association with sperm retrieval intracytoplasmic sperm injection outcomes.

Objective: To study the types and incidence of chromosomal abnormalities in infertile men with azoospermia and severe oligozoospermia in Qatar, and to compare the hormonal changes, testicular sperm retrieval rate, and intracytoplasmic sperm injection (ICSI) outcome between patients with chromosomal abnormalities and patients with idiopathic infertility.

Patients And Methods: This study involved the retrospective chart review of 625 infertile male patients attending an academic tertiary medical centre in Qatar. Retrieved information included data on medical history, family history, clinical examination, semen analysis, initial hormonal profiles, and genetic studies, ICSI, and sperm retrieval results.

Prostatic massage: a simple method of semen retrieval in men with spinal cord injury.

The aim of this study was to evaluate the efficacy of prostatic massage (PM) as a method for obtaining semen in men with spinal cord injury (SCI) and to evaluate the semen parameters in the semen samples obtained by this method. Sixty-nine patients with SCI underwent PM as a trial for semen retrieval. History taking, examination and hormonal assay analysis (follicle-stimulating hormone, luteinizing hormone, prolactin and testosterone) were performed in all patients.
