Dr. Victor Kuete is a scholar-scientist at the University of Dschang, Cameroon. Dr. Kuete has been a fellow of TWAS (2007), AUF (2008), DAAD (2009), University of Mainz-Germany (2010), Alexander von Humboldt (2012-2014), etc., and International Foundation for Science Grantee (2008-2009; 2012-2013). His Research Programme is focused on Pharmacognosy and Dr. Kuete mainly investigates African medicinal plants and isolated compounds as potential antimicrobial, antiviral, anti-proliferative agents. Dr. Kuete is the author of more than 120 scientific publications related to the bioactivity of medicinal plants and their derived products, and has also authored several books and more than forty book chapters.
Antioxidant nutrients, including vitamins A, C , E , B6 , B3 and selenium , zinc , magnesium , coenzyme Q10 , N-Acetyl-L-Cysteine , alpha lipoic acid , essential fatty acids and an excellent diet rich in lean protein, complex carbohydrates with adequate amounts of organic fruits and vegetables should also be adopted to provide a powerful nutritional defense against the negative effects of stress. The mind and body is one unit, interrelated and highly complex. Though it may take a while for scientists to truly understand the intricacies of how stress affects immunity and the aging process, today we know that having a positive attitude, a loving family, friends and effective stress-coping strategies enhance our immune system and give us a few extra years.
Posterior capsular opacification, also known as after-cataract, is a condition in which months or years after successful cataract surgery, vision deteriorates or problems with glare and light scattering recur, usually due to thickening of the back or posterior capsule surrounding the implanted lens, so-called 'posterior lens capsule opacification'. Growth of natural lens cells remaining after the natural lens was removed may be the cause, and the younger the patient, the greater the chance of this occurring. Management involves cutting a small, circular area in the posterior capsule with targeted beams of energy from a laser, called Nd:YAG laser capsulotomy, after the type of laser used. The laser can be aimed very accurately, and the small part of the capsule which is cut falls harmlessly to the bottom of the inside of the eye. This procedure leaves sufficient capsule to hold the lens in place, but removes enough to allow light to pass directly through to the retina. Serious side effects are rare.  Posterior capsular opacification is common and occurs following up to one in four operations, but these rates are decreasing following the introduction of modern intraocular lenses together with a better understanding of the causes.
