This study is the first report on antioxidant activities and chemical composition of S. cambodianum Baill. ethanolic leaf extract. The results showed that ethanolic extract had potent in vitro antioxidant activities in DPPH, ABTS•+ assays (the low concentrations of IC50 were 19.51 ± 0.78 μg/mL and 4.89 ± 0.07 μg/mL, respectively), and in RP, TAC methods (the Abs0.5 were 20.80 ± 0.26 μg/mL and 36.15 ± 1.03 μg/mL).

In this study, we used the reliable GC-FID/MS technique to analyze the methyl ester derivatives of 37 different kinds of fatty acids. The results showed that high saturated fat concentration in all samples was mostly palmitic acid, whereas the low unsaturated fatty acid content in the cis form was primarily oleic acid and linoleic acid. The amount of monounsaturated and polyunsaturated fats is quite low.

The highest luminescence product consists of spheroidal and relatively uniform particles with sizes around 0.6-1.0 µm. The variation of the precipitated precursor with temperature, the influence of sintering temperature on structure and luminescence, the mineralization role of boric acid and the chemical reactions that occur with generation of precipitated precursors and upon heating to give luminescent solid solution products are mentioned.

Ebook "Artemisia annua - Pharmacology and biotechnology" is an effective antimalarial agent, particularly for multi-drug resistant and cerebral malaria. However, the concentration of artemisinin in the plant is very low. Because the chemical synthesis of artemisinin is complicated and not economically feasible in view of the poor yield of the drug, the intact plant remains the only viable source of artemisinin production. Therefore, it is necessary to increase the concentration of artemisinin in A. annua to reduce the cost of artemisinin based antimalarial drugs.

Tamoxifen is used in low dose concentrations (20–40 mg per day) as a therapy for breast cancer but is known to have ocular side effects. In this case report, the foveal cone integrity in a tamoxifen-treated patient who complained of a small central scotoma in the left eye while reading was examined using high-resolution adaptive optics imaging.

In this paper, we reported NO2 sensors based on the ZnO nanorods with different sizes fabricated using a simple hydrothermal method without surfactants. The sensors offered the excellent response and sensitivity to NO2 at very low concentrations as low as 100 ppb. The influence of the size of the ZnO nanorods on the NO2 sensing response was focused.

Neuroblastoma (NB) is a childhood malignant tumor,50% of high-risk NB children still have recurrence, and the long-term survival rate is very low. NB tumors expressing high levels of BDNF/TrkB are associated with poor survival outcomes.In this study, we show that the trends of serum concentration of BDNF at different growth stages after birth, and explore the relationship with NB replase.

A portable and simple Raman scattering and photoluminescence spectroscopy system was set up for sensitive and rapid determination of nitrate/nitrite at low concentrations in water samples. The SERS (Surface Enhanced Raman Scattering) e active Ag/ITO substrates were prepared and employed to obtain the enhanced Raman scattering light from the sample.

Germanium doped photonic crystal fibers with differences in the layers' air hole diameters in the cladding are presented to obtain flat dispersion, small effective mode area, and low attenuation property for supercontinuum generation applications. The flatness and small value of the dispersion depend on the lattice geometry when the fibers have the same germanium doping concentration.

The model also promised a stable foundation to develop into a larger−scale model with more treatment stages and low electricity consumption. Moreover, it is possible to reuse the products produced by the ED model with two separate streams: a concentrated stream that can be applied to separate salts and a dilute stream that can be used as domestic water.

In this study, the sugarcane bagasse grafted with citric acid was used as a low-cost biosorbent for removal of dyes from the textile wastewater. The adsorption parameters such as initial pH values, dyes concentrations, adsorbent dosages and contact times were investigated by the batch experiments. The Freundlich and Langmuir adsorption isotherm models were used to evaluate the experimental data.
