anti-acne activity of methanolic extract against .

Background: Acne vulgaris is a skin infection widely seen in adolescents between 10-19 years with males affected more than females. It mainly affects the face but may also affect the back and chest. The symptoms vary with mild acne manifesting as comedones and moderate acne as inflammatory lesions (papulopustular), nodules, and mild scarring while severe acne has the same symptoms that have not subsided within 6 months of treatment.

Effect of Leaf Extract on Excision Wound Infections in Rats: Antioxidant, Antimicrobial, and Gene Expression Analysis.

The present study investigated the wound healing activity of leaf extract on an infected excision wound model in rats. Infection was induced using methicillin-resistant (MRSA) or An investigation was also done to study the effect of extract on the vascular endothelial growth factor (VEGF) and transforming growth factor-beta 1 (TGF-β1) gene expression in vitro using human keratinocytes (HaCaT). The methanol extract of leaves was analyzed for the presence of phytochemicals by LCMS.

Leaf Extract Promotes Healing of Infected Wounds in Diabetic Rats: Evidence of Antimicrobial, Antioxidant and Proliferative Properties.

is known to possess wound healing activity. The present study evaluated the healing properties of methanolic extract of leaves in excision wounds infected with methicillin-resistant (MRSA) or in diabetic rats. An in vitro study was also carried out to determine the gene expression of VEGF and TGF-β1.

Effect of sampling time on the heavy metal concentrations of brown algae: A bioindicator study on the Arabian Gulf coast.

Macroalgae have often been studied as bioindicators for heavy metal pollution on sea coasts including the Arabian Gulf. On the Arabian Gulf coasts, heavy metals are continuously being released by industrial activities and therefore, pollution monitoring is needed. Biomonitoring studies using macroalgae has given highly different assessments due to the variability in algal species and sampling time points.

Accumulation of heavy metals in a macrophyte Phragmites australis: implications to phytoremediation in the Arabian Peninsula wadis.

Heavy metal-polluted wetlands could be remediated by harvesting metal accumulating plants, i.e., using phytoextraction.

Current prospective in using cold-active enzymes as eco-friendly detergent additive.

Advanced developments in the field of enzyme technology have increased the use of enzymes in industrial applications, especially in detergents. Enzymes as detergent additives have been extensively studied and the demand is considerably increasing due to its distinct properties and potential applications. Enzymes from microorganisms colonized at various geographical locations ranging from extreme hot to cold are explored for compatibility studies as detergent additives.

Potential use of green algae as a biosorbent for hexavalent chromium removal from aqueous solutions.

The hexavalent chromium Cr(VI) poses a threat as a hazardous metal and its removal from aquatic environments through biosorption has gained attention as a viable technology of bioremediation. We evaluated the potential use of three green algae (, and ) dry biomass as a biosorbent to remove Cr(VI) from aqueous solutions. The adsorption capacity of the biomass was determined using batch experiments.

Characterization of Cladosporium Species by Internal Transcribed Spacer-PCR and Microsatellites-PCR.

Background: This investigation compared genetic similarities and diversities within and among Cladosporium species populations using the two PCR-based markers; Internal Transcribed Spacer (ITS)-PCR and microsatellite-PCR.

Methodology: Nuclear ribosomal DNA internal transcribed spacers have been used to analyze intraspecific and interspecific relationships in various fungi. In the present study, the internal transcribed spacer (ITS)-PCR and microsatellite-PCR were used to identify the genetic diversities in Cladosporium species.

Adsorptive removal of cadmium ions by Spirulina platensis dry biomass.

Cadmium is one of the most toxic substances found in aquatic ecosystems. This metal tends to accumulate in photosynthetic plants and fish and is transferred to humans causing many diseases. It has to be removed from our environment to reduce any health risks.

Lead removal by Spirulina platensis biomass.

In this investigation, we report on the biosorption of Pb (II) from aqueous solutions by the nonliving biomass of the micro-alga (cyanobacterium) Spirulina platensis. Propagation of the micro-alga was carried out in outside oblong raceway ponds. The biomass was cleaned, dried and used for the investigation.
