objective:  unaccustomed and intense eccentric exercise is a common cause of delayed-onset muscle soreness (doms). there are multiple remedies for the treatment of doms, but its clinical and laboratory pieces of evidence are scarce. currently, the treatments proposed for doms are numerous and include pharmaceuticals, herbal remedies, stretching, massage, nutritional supplements, and other alter...

objective: malaria is an infectious disease commonplace in tropical countries. for many years, major antimalarial drugs consisted of natural products, but since 1930s these drugs have been largely replaced with a series of synthetic drugs. this article tries to briefly indicate that some plants which previously were used to treat malaria, as a result of deficiencies of synthetic drugs, have rev...

recently, some natural products have been used in the fields as alternative to synthetic compounds, to minimize the negative impacts to the environment. this study aimed to verify the effects of neem-based bio-pesticide in causing acute toxicity for a fish and chronic toxicity for a microcrustacean. to this end, danio rerio and daphnia magna were exposed to various concentrations of a neem-base...

introduction: angiogenesis, the process of new blood vessel formation from pre-existing vessels, has important physiological roles in embryonic development, female reproduction cycle, and wound healing. it is also crucial for pathological processes in several diseases especially tumor growth and metastasis. thereby, inhibition of angiogenesis as an addition to the conventional therapies such as...
