An overview of Neem (Azadirachta indica) and its potential impact on health

Global health and medical practice seek to merge alternative medicine with evidence-based medicine for a better understanding of the metabolic process and its effects in the human body. An example is the use of complementary medicine like phytotherapy. Azadirachta indica (Neem), a tree originally from India and Myanmar, called by many “The village pharmacy” or “Divine tree” because of its many health properties. In recent times, Neem-derived extracts have been shown to work from anywhere from insect repellent, to supplements to lower inflammation, diabetic control, and even to combat cancer. Herein, we state the health benefits found in diverse compounds and extracts derived from Neem, highlighting the mechanisms and pathways in which Neem compounds produce their effects, while warning that the improper and unstandardized conditions to produce extracts can lead to health issues, particularly certain compounds might have damaging effects on the liver and kidneys

Corrosion Prevention by Conducting Polyaniline based Paints on Low Carbon Steel

Abstract-Conducting polyaniline powder was synthesized chemically and paints containing conducting polyaniline powder were applied on low carbon steel samples. The conducting polyaniline powder was characterized by UV-Visible absorption spectroscopy and the morphology of paint coating on low carbon steel was studied by scanning electron microscopy. The corrosion protection performance of the coatingwas evaluated by using electrochemical impedance spectroscopy, alternating immersion and salt spray. It has been found that the 2 wt % polyanilinehydrochloric acid based paint coating offers significant corrosion protection to low carbon steel in chloride medium. In addition, these paintcoatings withstand drying and wetting cycles in atmosphere

157-164Graded doses of 50% ethanolic extract of dried fruit pulp of Aegle marmelos (AME) (100, 200 and 400 mg/kg) daily for 14 days in acetic acid (AA)-induced colitis in rats showed 200 mg/kg of AME as an optimal effective dose against AA-induced colonic damage score and weight. This dose (200 mg/kg; po) was further studied in AA-induced colitis for its effects on various physical (mucous/blood in stool, food and water intake and body weight changes), histology, antibacterial activity and biochemical parameters like free radicals (nitric oxide and lipid peroxidation), antioxidants (superoxide dismutase, catalase and reduced glutathione) and myeloperoxidase (acute-inflammatory marker) activities in rat colonic tissue. AME decreased colonic mucosal damage and inflammation (macroscopic and microscopic), mucous/bloody diarrhea, fecal frequency and increased body weight affected in AA-induced colitis. AME showed significant antibacterial activity and enhanced the antioxidants but decreased free radicals and myeloperoxidase activities thereby decreasing tissue damage and inflammation and thus, affording ulcer healing.
