The in vitro antioxidant activity of n-hexane, chloroform, ethyl acetate and alcoholic fraction of the total ethanolic extract of the leaves of Garcinia brasiliensis have been tested using various antioxidant model systems viz., ferric reducing power assay and hydrogen peroxide scavenging assay. Ethyl acetate fraction is found to possess higher ferric reducing power and superoxide radical scavenging activity. The estimation of total phenolic and flavonoid contents of the various fractions are studied and the ethyl acetate fraction is found to possess high total phenolic and flavonoid content, thus correlating it with the antioxidant potential of the ethyl acetate...

Nano-sized ZnO particles of specific morphology were synthesized using the plant leaf extracts of Aloe vera. In modern science Nanotechnology is an ablaze field for the researchers. Nanoparticles having a size of 1-100 nm in one dimension are used significantly concerning medical chemistry, atomic physics and all other known fields. Nanoparticles are used immensely due to its small size, orientation, physical properties, which are reportedly shown to change the performance of any other material which is in contact with these tiny particles. The biological approach is the most emerging approach of preparation, because, this method is easier than the other methods, eco-friendly and less time consuming. The semiconductor ZnO has gained substantial interest in the research community in part because of its large exciton binding energy 60 meV which could lead to lasing action based on exciton recombination even above room temperature. The Green synthesis was done by using the methanol of Aloe vera extract and zinc oxide. A fixed ratio of plant extract to metal ion was prepared...

Now days the potential toxic effect of heavy metals in the aquatic organisms has been intensively studied. The present study was aimed to determine the proximate composition and the heavy metal concentrations (Cd, Pb & Cr) of three different marine fish species Grey mullet (Mugil cephalus), Red snapper (Lutjanus sanguineus), and Indian sardine (Sardinella longiceps) along with the water sample collected from the southeast coast region located in Pondicherry state. These results revealed that the proximate composition of L. sanguineus had higher protein content (19.98%) and S. longiceps had higher fat content (10.03%), Fresh M. cephalus had higher moisture content (84.04%) whereas L. sanguineus had the highest ash content (2.59%) respectively. The metal concentration in seawater was found in the following order: Cr 0.91±0.04 > Cd 80±0.03 > Pb 0.08±0.01. The biomonitoring of the heavy metal concentration in the fish falls in the following order: Chromium 1.62±0.57 (Mugil cephalus) > 1.12±0.32 (Sardinella longiceps) > 0.90±0.04 (Lutjanus sanguineus). Lead 0.17±0.04 (Sardinella longiceps) > 0.33±0.07 (Lutjanus sanguineus) > 0.33±0.07 (Mugi cephalus)....

Artemisia vulgaris leaves are known to have anectodatal evidence of antioxidant activity which can be of use as an anti – stress remedy. However, this claim is yet to be proven and no available data on its adaptogenic potential hence, this study aimed to determine the adaptogenic potential of Artemisia vulgaris leaf extract on male albino rats using acute restraint stress. Six male albino rats were used as test animals and were subdivided into the following: control group, untreated normal group, negative group, and three doses of the test solution [500mg/200g rat (T1), 250mg/200g rat (T2), and 150 mg/200g rat (T3)]. T3 rats exhibited the highest adaptogenic activity of -3,111.11% based on cholesterol levels and -1916.67% based on glucose levels. Moreover, glucose levels of T2 and T1 rats were -345.41% and -6.60%, respectively while for their cholesterol levels, T2 exhibited -277.78% and T1 exhibited -90.05%. The median effective dose of the test suspension based on cholesterol levels and glucose levels is 169.70 mg/200g rat and 151.81mg/200g rats, respectively. From...

Pharmacists in all practice settings are in a key position to start providing care to people, who have diabetes or are at risk of developing it, or to expand and improve their care. Pharmacy programs for patients with diabetes involve activities ranging from identifying and referring at-risk patients, to supporting American Diabetes Association recognized multi-disciplinary diabetes care programs. Pharmacists can help identify patients with diabetes through screening and should target patients at high risk, people with a family history of the disease, and women with a history of gestational diabetes or who delivered a baby weighing more than nine pounds. Patient education should be provided immediately after diagnosis, at a second stage at which time a patient assessment can be performed, and at a third stage during which patients can receive continuing education to reinforce concepts and motivational boost. One of the pharmacist’s most important roles is the referral of patients to the other members of the diabetes care team. The pharmacist can play an important role in diabetes...
