A thiol-functionalized zirconium metal-organic cage for the effective removal of Hg from aqueous solution.

The mercury ions in waste water have threatened public health and environmental protection. In this sense, novel materials with outstanding performances for removal of Hg are imperative. Herein, we demonstrate a thiol-functionalized zirconium metal-organic cage (MOC-(SH)) with excellent dispersion displays ideal properties for Hg capture.

[Glutathione and male reproduction].

Reduced glutathione (GSH) , the most abundant non-protein thiol in mammalian cells, exists extensively in the human body and plays a key role in many biological processes, including the synthesis of proteins and DNA and the transport of amino acids, especially in protecting cells against oxidation. GSH also shows its important clinical value in the treatment of many diseases. It has been reported that GSH also widely exists in the male reproductive system and has a therapeutic role in male infertility.

[Determination of uric acid in the expressed prostatic secretion of chronic prostatitis patients and its clinical significance].

Objective: To determine the level of uric acid (UA) in the expressed prostatic secretion (EPS) of chronic prostatitis patients and explore its clinical significance.

Methods: A total of 91 patients with chronic prostatitis diagnosed by NIH standard were divided into a III A (n = 48) and a III B (n = 43) group, and healthy volunteers were selected as the control. The scores on the NIH-Chronic Prostatitis Symptom Index (CPSI) and the WBC count, pH value and UA level in EPS were evaluated for all the three groups.

[Evaluation of sperm mitochondrial membrane potential by JC-1 fluorescent staining and flow cytometry].

Objective: To investigate the feasibility and clinical significance of detecting sperm mitochondrial membrane potential (MMP) by JC-1 fluorescent staining and flow cytometry, and to explore the relationship between the results of JC-1 staining and seminal parameters.

Methods: Sixty-three semen samples were divided into a fertile (n = 31) and an infertile group (n = 32) and underwent computer-assisted semen analysis (CASA). All the samples were washed, followed by JC-1 staining and evaluation of sperm MMP by flow cytometry.

[Clinical, molecular and cytogenetic studies on 4 patients with 46, XX (SRY positive) male syndrome].

Objective: To analyze the clinical, molecular and cytogenetic features of 46, XX (SRY positive) male syndrome.

Methods: The clinical features of 4 patients with 46, XX (SRY positive) male syndrome were analyzed retrospectively. Karyotyping, FISH, PCR amplification of the SRY gene, and Y-chromosome microdeletion were performed to study their molecular cytogenetic features.
