Study on the Anti-Aging Performance of Different Nano-Modified Natural Ester Insulating Oils Based on Molecular Dynamics.

In order to investigate the anti-aging performance of nano-modified natural ester insulating oils, in this paper, two different types of nanoparticles are selected to modify insulating oils. We studied the microscopic mechanism of nano-modified models using molecular simulation techniques. Three models were established: an oil-water model without the addition of nanoparticles and two which contained nano-FeO and nano-AlO particles, where the concentration of water was 1 wt.

Cobalt-catalyzed ring-opening addition of azabenzonorbornadienes via C(sp)-H bond activation of 8-methylquinoline.

The first ring-opening addition of a benzylic C(sp)-H bond to azabenzonorbornadienes is demonstrated. The reaction proceeded under the catalytic system of [Cp*CoI(CO)], AgSbF and Fe(OAc) in PhOMe. The methodology showed a good substrate scope with up to 96% yield.

Male sexual dysfunction: A review of literature on its pathological mechanisms, potential risk factors, and herbal drug intervention.

Sexual dysfunction (SD) is a disorder of sexual behavior and sexual sensation that appears as an abnormality or absence of sexual psychology and physiological reaction. It is a general term for many different symptoms includes several aspects, erectile dysfunction (ED), failure of sexual intercourse and loss of libido/desire. According to statistics, 52% of 40˜70 year old men suffer from varying degrees of SD.

Involvement of growth factors in diabetes mellitus and its complications: A general review.

Diabetes mellitus (DM) is a major endocrine metabolic disease and is marked by a lack of insulin. The complication of DM is one of the most difficult problems in medicine. The initial translational studies revealed that growth factors have a major role in integrating tissue physiology and in embryology as well as in growth, maturation and tissue repair.
