Multiple sclerosis(Ms)is the most common chronic disease of the central nervous system(CNs)in young adults and represents the first cause of severe handicap,originally non-traumatic(Oh et al.,2018).Ms is chara cterized by the infiltration of auto reactive lymphocytes specific to myelin through the blood-brain barrier,which results in the appearance of inflammatory demyelinating lesions caused by the death of the central nervous system myelinating cells,oligodendrocytes(Oh et al.,2018).There is a prevalence sexual with a ratio of three times more affected women than men.

Progeria is a rare genetic disease that causes accelerated aging and death in children at a mean age of 13.5 years. An?aminobisphosphonate-statin combination has been shown to reduce the toxicity of the mutated protein, progerin, in progeria patient cell cultures and in a mouse model of the disease. This combination is currently being tested in a European Therapeutic Trial for progeria in Marseille (*** identifier NCT00731016). Progerin has been shown to be produced by skin cells during physiological aging. The objective of this study was to assess the efficiency of a new and original cosmetic formulation containing alendronate and pravastatin sodium salts, reduce crow’s feet wrinkles, and cheek hollow in a double blind, randomized and placebo controlled comparative study. Three cosmetic preparations were evaluated using Fast Optical in vivo Topometry of human skin (FOITs): one containing sodium alendronate and sodium pravastatin, a placebo, and a commercial anti-aging product. Fifty-seven female and twenty-five male volunteers between 51 and 71-year-old were selected. Each subject tested two of the three products once a day, in the evening, by spreading each selected product on one side of the face. skin micro-relief was analyzed at 0, 28, 56 and 84 days. statistical analysis of 7 clinical qualitative (left or right side of face, gender, and 3 skin types) and 6 quantitative parameters (age, weight at each test time, wrinkle clinical grade at inclusion time) showed no statistical differences between the three tested products. In contrast, most of the 8 quantitative FOITs parameters describing skin micro-relief were statistically improved by the alendronate-pravastatin combination compared to the placebo or to the commercial anti-aging product. A cosmetic preparation containing alendronate and pravastatin sodium salts exhibited anti-aging effects by reducing crow’s feet wrinkles and restoring cheek volume.

Chronic epididymitis and varicocele are frequently observed genital disorders in men consulting for couple infertility, but their impact on semen characteristics at the time of infertility consultation is still a matter of debate. We investigated 652 male partners of couples who had their first infertility consultation between 1999 and 2015 in Argentina. Men with chronic epididymitis （n = 253）, Grade III varicocele （n = 106）, and both conditions （n = 125） were compared with a control group （n = 168） composed of men without these disorders or any other recognized causes of male infertility. We showed that men who presented isolated chronic epididymitis were more likely to have high percentages of low sperm motility and abnormal sperm morphology as well as a high number of white blood cells. Men with isolated Grade III varicocele had low sperm production and motility and an increased percentage of abnormal sperm morphology. Finally, men who simultaneously presented chronic epididymitis with Grade III varicocele had a low sperm motility and increased percentage of abnormal sperm morphology as well as a high number of white blood cells. Physical examination of the genital organs may identify common disorders, potentially involved as causal factors of patient＇s infertility. These disorders are associated with specific seminal profiles that should help in identifying the best treatment from the available therapeutic options, effectiveness, safety, and allowing as much as possible natural conception.
