inhibition of biofilm and virulence factor production in azole-resistant strains of isolated from diabetic foot by stabilized tin (IV) oxide nanoparticles.

The advent of nanotechnology has been instrumental in the development of new drugs with novel targets. Recently, metallic nanoparticles have emerged as potential candidates to combat the threat of drug-resistant infections. Diabetic foot ulcers (DFUs) are one of the dreadful complications of diabetes mellitus due to the colonization of numerous drug-resistant pathogenic microbes leading to biofilm formation.

Carrageenan oligomers and salicylic acid act in tandem to escalate artemisinin production by suppressing arsenic uptake and oxidative stress in Artemisia annua (sweet wormwood) cultivated in high arsenic soil.

The present study is aimed to elucidate the effects of concomitant application of irradiated carrageenan (IC) oligomers and salicylic acid (SA) on Artemisia annua L. varieties, viz. "CIM-Arogya" (tolerant) and "Jeevan Raksha" (sensitive) exposed to arsenic (As) stress.

Comparative genomic analysis reveals evolutionary and structural attributes of MCM gene family in Arabidopsis thaliana and Oryza sativa.

The mini-chromosome maintenance (MCM) family, a large and functionally diverse protein family belonging to the AAA+ superfamily, is essential for DNA replication in all eukaryotic organisms. The MCM 2-7 form a hetero-hexameric complex which serves as licensing factor necessary to ensure the proper genomic DNA replication during the S phase of cell cycle. MCM 8-10 are also associated with the DNA replication process though their roles are particularly unclear.

Ecological variations and role of heat shock protein in L. in response to temperature regimes of Tabuk, Saudi Arabia.

L. (Compositae) are shrubby herbs growing wildly in Tabuk region and distributed in the desert regions. This region is characterized by extremely variable environmental conditions where the temperature varies from extreme low to extreme high.

Assessment of biotransfer and bioaccumulation of cadmium, lead and zinc from fly ash amended soil in mustard-aphid-beetle food chain.

The present study investigates the extent of biotransfer and bioaccumulation of cadmium (Cd), lead (Pb) and zinc (Zn) from fly ash amended soil in mustard (Brassica juncea)-aphid (Lipaphis erysimi)-beetle (Coccinella septempunctata) food chain and its subsequent implications for the beetle. The soil was amended with fly ash at the rates of 0, 5, 10, 20 and 40% (w/w). Our results showed that the uptake of Cd, Pb and Zn from soil to mustard root increased with the increase in fly ash application rates, but their root to shoot translocation was relatively restricted.

Piriformospora indica: Potential and Significance in Plant Stress Tolerance.

Owing to its exceptional ability to efficiently promote plant growth, protection and stress tolerance, a mycorrhiza like endophytic Agaricomycetes fungus Piriformospora indica has received a great attention over the last few decades. P. indica is an axenically cultiviable fungus which exhibits its versatility for colonizing/hosting a broad range of plant species through directly manipulating plant hormone-signaling pathway during the course of mutualism.

Role of DNA barcoding in marine biodiversity assessment and conservation: An update.

More than two third area of our planet is covered by oceans and assessment of marine biodiversity is a challenging task. With the increasing global population, there is a tendency to exploit marine resources for food, energy and other requirements. This puts pressure on the fragile marine environment and necessitates sustainable conservation efforts.

Recent incidence and descriptive epidemiological survey of breast cancer in Saudi Arabia.

Objective: To review and analyze the pattern of breast cancer (BC) in the Kingdom of Saudi Arabia (KSA).

Methods: A retrospective review of BC among female patients was conducted at the Faculty of Sciences, Department of Biology, University of Tabuk, Tabuk, Saudi Arabia from January 1990 to December 2014. This report contains information obtained from the Saudi Cancer Registry and from King Faisal Specialist Hospital and Research Center.

Phytochemical, antioxidant and mineral composition of hydroalcoholic extract of chicory (Cichorium intybus L.) leaves.

The phytochemical, antioxidant and mineral composition of hydroalcoholic extract of leaves of Cichorium intybus L., was determined. The leaves were found to possess comparatively higher values of total flavonoids, total phenolic acids.
