Evaluation and optimization of nanosuspensions of Chrysanthemum coronarium and Azadirachta indica using Response Surface Methodology for pest management.

The rapidly emerging field of nanotechnology is considered an important achievement in the agriculture sector to increase the pest mortality rate and improve the crop production. The present study evaluates the novel pesticidal and anti-microbial activities of Chrysanthemum coronarium and Azadirachta indica in the nano-suspensions form. The anti-solvent precipitation method was used to formulate nano-suspensions proposed by Response Surface Methodology (RSM).

PTU, a novel ureido-fatty acid, inhibits MDA-MB-231 cell invasion and dissemination by modulating Wnt5a secretion and cytoskeletal signaling.

Migration and invasion promote tumor cell metastasis, which is the leading cause of cancer death. At present there are no effective treatments. Epidemiological studies have suggested that ω-3 polyunsaturated fatty acids (PUFA) may decrease cancer aggressiveness.

Identification of Hypotensive Biofunctional Compounds of and Evaluation of Their Angiotensin-Converting Enzyme (ACE) Inhibition Potential.

The aim of this study was to identify and characterize the bioactive compounds of responsible for the treatment of hypertension and to explore their mechanism of action as angiotensin-converting enzyme (ACE) inhibitors. Bioactive fractions like alkaloids, flavonoids, steroids, and tannins were extracted and evaluated for their ACE inhibition potential. Among them, only flavonoid-rich fraction showed high ACE inhibition potential with IC value of 28.

Synergistic interactions of polyphenols and their effect on antiradical potential.

The aim of the current study was to evaluate interactions among polyphenols from different plants and their effect on antioxidant potential. Different mixtures of plant extracts of Crataegus oxyacantha (C), Elettaria cardamomum (Cr), Terminalia arjuna (T) and Rauvolfia serpentina (R) were prepared and evaluated for total phenolics, flavonoid contents, and antioxidant activity. A correlation was also established between total phenolics, flavonoids and antioxidant activity.

Protection of DNA during oxidative stress and cytotoxic potential of Artemisia absinthium.

Medicinal plants are rich in secondary metabolites (alkoloids, glycosides, coumarins, flavonides, steroids, etc.) and considered to be more effective and a safer alternative source to manage a variety of diseases related to liver, heart and kidney disordered.

Dopamine-β-Hydroxylase Activity and Levels of Its Cofactors and Other Biochemical Parameters in the Serum of Arsenicosis Patients of Bangladesh.

Dopamine-β-hydroxylase (DBH) is a neurotransmitter (catecholamine)-mediating enzyme, which catalyzes the formation of norepinephrine from dopamine. The levels of DBH activity, its coenzyme (ascorbic acid) and cofactor (Cu(++)) and other biochemical parameters were measured in the serum of 32 arsenicosis patients of Bangladesh at three different age groups, namely, group 1 (10-18 years, 9 patients), group 2 (19-40 years, 14 patients) and group 3 (41-70 years, 9 patients) of the locality of Stadium Para of Meherpur district of Bangladesh. The values were compared with the same number of age-matched normal healthy individuals of the respective group.
