Oxidative stress associated with bacterial infections, are recognized as being a key factor in the appearance and complications of many chronic pathologies. To help overcome these difficulties, herbal remedies are one of the alternatives for the development of traditionally improved drugs. The objective of this work is to evaluate the antiradical and antibacterial activities of the ethanolic extract of the bark of the trunk of Terminalia avicennioides. Plant used in traditional medicine in Chad in the treatment of infectious diseases.

The endeavor of this research accounts for a superficial green route scheme by using an extract of leaves of Smilax aspera as a stabilizing and capping agent. Zinc Oxide nanoparticles (ZnO-NPs) were examined through UV-visible Spectrophotometer, X-Ray Diffraction (XRD), EDX (Energy Dispersive X-rays spectroscopy), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM). The NPs demonstrates potential photo catalytic activity for the degradation of Methyl Orange (MO) and Methylene Blue (MB) dyes upon exposure to sunlight.

This experimental study evaluated the release of fluoride and several minerals related to remineralization from novel functional cement, apatite ionomer cement (AIC), and its anti-bacterial properties compared with glass ionomer cement (GIC) and surface pre-reacted glass-ionomer filler containing composite resin (giomer). Conventional GIC (Fuji III, GC Co., Tokyo, Japan) was used as the control and fundamental materials. In the AIC powder, 28% wt of GIC powder was replaced with spherical-shaped hydroxyapatite powder. The giomer, BeautiSealant (Shofu Co., Kyoto, Japan), was used as a positive control. Each specimen was immersed in deionized water and analyzed by inductively coupled plasma atomic emission spectrometry (for Al, Si, P, Ca and Sr) and a fluoride-selective electrode. Antibacterial activity against Streptococccus mutans was evaluated using the adenosine-5’-triphosphate luminescence method. Concentrations of released ions from AIC specimens were significantly higher than those from GIC and giomer specimens. Regarding antibacterial activity, luminescence intensity of the AIC group was significantly lower than that of the control and giomer groups. It was concluded that AIC could be a most suitable material for pit and fissure sealant for enamel remineralization and anti-cariogenic and -bacterial activity.

Streptomyces species are medically, industrially, and microbiologically important bacteria that are found in soils and other habitats. Streptomyces isolates and QUBC97 were cultured on a new medium (CCG). Agar plug diffusion test showed antibacterial activity. N-butanol extracts analysed by silica thin layer chromatography (TLC), HPLC purified and identified by MS analysis. QUBC97 was identified based on morphology, PCR, and DNA sequencing of two loci.

The first patient was a 77 year old man who had been on abiraterone for 12 months before his phosphorous was checked. At that point, it was 0.6 mg/dl, which is severely decreased. A full work up for hypophosphatemia showed normal parathyroid hormone and 25-hydroxyvitamin D. A urine study showed inappropriate excretion of phosphorous along with aminoaciduria and normoglycemic glucosuria.
