Study of biochemical predictors of bone loss and bone mineral density in postmenopausal women

Measurement of bone remodelling biomarkers combined with assessing bone mineral density (BMD) helps in identification of postmenopausal women at  increased risk of  recurrent fractures and in  monitoring therapeutic efficacy.
Objective: To assess BMD using ultrasound based regional bone densitometry and to determine the levels of serum markers of bone turnover in postmenopausal women.

Optimization of indole-3-acetic acid production by Bacillus subtilis TIB6 using response surface methodology

The influence of carbon, nitrogen sources and tryptophan supplementation on indole-3-acetic acid (IAA) production of Bacillus subtilis TIB6 isolated from pepper rhizosphere, Tay Nguyen province of Viet Nam was investigated and obtained results showed that sucrose and yeast extract were the most favorable carbon and nitrogen sources for TIB6’s IAA production, respectively, while the presence of L-tryptophan in culture medium stimulated the formation of IAA.

Turkish peasant vis-à-vis the republic

The Turkish Republican Revolution followed the National Struggle for the independence of the remaining Turkish sections of the former Ottoman State. The republican material gains as well as social changes and opinions made scene on city centers soon after if not all at once. But republican ways’ and gains’ “leaking into” villages were to take much more time, overcoming resistance and natural obstructions on the way. The Trial of village institutions and the mechanization of agriculture are two important events on the way to modernization of the countryside.

Assessment of impact significance of oil spill in the Niger Delta, Nigeria

Oil pollution is a serious threat to the bio-physical environment and consequently the socio-economic life of the people living within the oil bearing environment. This paper examined the significance of oil contamination on the socio-economic life of the people of Mgbede in Rivers State, Ekakpamre and Kwale in Delta State, with a view to determining the need for mitigation. Survey was conducted on the communities and with a well-structured questionnaire the data for the study were generated.

Woody plant diversity along disturbance gradients in the northern afro-montane forests of the bale mountains, Ethiopia

The effects of human disturbances on woody plant species diversity was assessed by comparing species richness, Shannon diversity and evenness, population abundance and composition along three disturbance gradients in the northern Bale Mountains, Ethiopia. Data on woody plant species were collected in six forest patches along three levels of disturbances in 20 by 20 m-2 quadrates in each forest patches.

Phytochemical analysis in different solvent extracts of padina tetrastromatica

The phytochemical constituents of the aqueous, acetone and methanol extracts of Padina tetrastromatica were studied. The qualitative analysis revealed the presence of alkaloids, steroids, tannin, phenols, saponins, terpenoids and flavonoids. The methanol extract of Padina  tetrastromatica, was used for quantitative estimation of alkaloid, tannin, flavanoid, phenol, Chlorophyll, Protein and Carbohydrate.

Qualitative phytochemical screening in different solvents of rauwolfia serpentina (Linn.) Benth., ex Kurz. stem

Indian medicinal plant (Rauwolfia serpentina (Linn.) were analyzed for their phytochemical constituents. The results revealed the presence of bioactive constituents comprising carbohydrate, glycosides, steroids, alkaloids, flavonoids, saponin and triterpenes. Rauwolfia serpentina (Linn.) is a good source of glycosides, alkaloids, flavonoids, and triterpenes. Hence it is used for the extraction of useful drugs.

Isolation of protein from cell free culture filtrate: A noble approach

Bacteria are well known for their ability to liberate proteins and enzymes into their environment. Pseudomonad sp. being important micro-organisms produces wide range of extra-cellular enzymes including proteases. The pseudomonad strains R62 and R81 has been used in this study for electrophoresis analysis of extracellular protease enzymes which were present in the cell free culture of nutrient broth (NB) and protease specific broth (PB) media.

Characterization of a new Al3+-selective fluorescent probe based on naphthalene derivative

A new compound derived from naphthalene was successfully characterized as Al3+-selective fluorescent probe. The proposed probe has better selectivity and sensitivity compared to other tested metal ions. A prominent fluorescence enhancement was observed in the presence of Al3+, accompanied by the change in the absorption spectrum.

Prevalence and causes of infertility among women of Jammu and Kashmir

The problem of infertility has not given its due attention in India because it is not a life threatening condition. Infertility is a life crisis with invisible losses and its consequences are manifold. The study was done to find out the prevalence and causes of infertility in ethnic population of J and K. The study was carried out in the hospital settings. The finding of the study Indicates that Jammu region shows highest prevalence of infertility rate followed by Kashmir region, where as Ladakh region shows the lowest prevalence.
