BACKGROUND: Systemic therapies are routinely used for the management of cutaneous warts. However, there is a lack of evidence-based data on their effectiveness. OBJECTIVE: To assess the evidence for the efficacy of systemic treatments for cutaneous warts. METHODS: We designed a systematic review of the randomized controlled clinical trials (1962 to April 2010) investigating systemic therapies for the treatment of cutaneous warts. We obtained data from MEDLINE, PubMed, Current Contents, reference lists, and specialist textbooks, with no restriction on language.

To assess the efficacy and safety, essential (Cl, Co, Cr, Fe, K, Mn, Na, Se, Zn), toxic (As, Br, Hg, Sb,) and other elements (Ba, Ce, Cs, Eu, Rb, Sc) were determined in Emblica officinalis (EO), Terminalia belerica (TB) and Terminalia chebula (TC) using instrumental neutron activation analysis. These herbs contain K as a major element, while Co, Cr and Na in EO, Fe, K and Mn in TB and Cl and Zn in TC are the highest.

The emphasis on harmful substances that may occur in potable waters has almost obscured the fact that important beneficial constituents are commonly present. The chemical substances in water that make positive contributions to human health act mainly in two ways: (i) nutritionally, by supplying essential macro and micro elements that the diet (excluding water) may not provide in adequate amounts (for example, Mg, I and Zn); and (ii) by providing macro and micro elements that inhibit the absorbtion and/or effects of toxic elements such as Hg, Pb and Cd.

Nutritional modulation is one approach to successful aging. In animals, dietary restriction increases life span. Alterations in the macronutrient and micronutrient constituent of the diet can modulate gene expression. Anorexia is common in elderly persons. The results of studies in animals suggest that aging is associated with a decrease in the opioid feeding drive and an increase in the satiating effect of cholecystokinin. Unrecognized depression is a common, treatable cause of anorexia and weight loss in elderly persons.

The recent Expert Consultation of World Health Organization (WHO)/Food and Agricultural Organization (FAO)/International Atomic Energy Agency (IAEA) defined essentiality of a trace element as follows: "An element is considered essential to an organism when reduction of its exposure below a certain limit results consistently in a reduction in a physiologically important function, or when the element is an integral part of an organic structure performing a vital function in the organism." This definition omits a previous postulate that the mechanism of action of an essential trace e

OBJECTIVE: To make a survey of the nutritional composition of the diets of centenarians. METHODS: Thirty-four centenarians were selected as subjects. Retrospective surveys were made on the variety and amounts of food consumed and their nutritional composition. Physical examinations with laboratory tests such as cardiograms, ultrasonic B rays, and blood, urine and hair tests were performed. Neutron activation testing was done on hair content. The transmission turbidimetric method was used to measure apolipoprotein content.

A major obstacle to the progress of the Millennium Development Goals has been the inability of health systems in many low- and middle-income countries to effectively implement evidence-informed interventions. This article discusses the relationships between implementation research and knowledge translation and identifies the role of implementation research in the design and execution of evidence-informed policy.

Medicinal plants described in the Indian "Ayurvedic" literature viz. Tulsi (Ocimum sanctum), Gulvel (Tinospora cardifolia), bitter Neem (Azadirachta indica), Kanher (Nerium Andicum), Vekhand (Acorus calamus), and Peacock's feather (ash) were analyzed for minor and trace elements by instrumental neutron activation analysis.

Specific parts of several plants (fruits, leaves, stem, bark, and roots) often used as medicines in the Indian Ayurvedic system have been analysed for 20 elements (As, Ba, Br, Ca, Cl, Co, Cr, Cu, Fe, K, Mn, Mo, Na, P, Rb, Sb, Sc, Se, Sr and Zn) by employing instrumental neutron activation analysis (INAA). The samples were irradiated with thermal neutrons in a nuclear reactor and the induced activity was counted using high resolution gamma ray spectrometry. Most of the medicinal herbs have been found to be rich in one or more of the elements under study.
