Biochemical and In Silico Aspects of Active Compounds From Nyctanthes arbor-tristis Flower As Antidiabetic Agent.

Targeting alpha-glucosidase (maltase-glucoamylase [MGAM] and sucrase-isomaltase [SI]) under diabetes conditions is important to overcome hyperglycemia. Moreover, it is necessary to mitigate hyperglycemia-mediated oxidative stress to evade the progression of diabetes-associated secondary complications. Hence, in the present study, under-explored Nyctanthes arbor-tristis flowers (NAFs) were studied for inhibition of alpha-glucosidase activities.

Scanning electron microscopic investigation on Chicory tribe (Compositae) botanical sources and their antimicrobial potential.

This study discusses the micro-level structural details of Cichorieae pollen sources elucidated by scanning electron microscopy (SEM) and explains their symmetry and morphometry. The in-depth knowledge from the electron ultrastructure of Asteraceae pollen has provided insights into enhanced pollen morphology, and the antimicrobial significance of species under study presents novel avenues for their natural defense mechanisms in the development of antimicrobial agents. In this research, both quantitative and qualitative features of pollen were examined.

Assessment of the botanical origin of Saudi Arabian honey samples to identify pollen with chromatographic tools and packing and storage.

The increasing demand for honey purification and authentication necessitates the global utilization of advanced processing tools. Common honey processing techniques, such as chromatography, are commonly used to assess the quality and quantity of valuable honey. In this study, 15 honey samples were authenticated using HPLC and GC-MS chromatographic methods to analyze their pollen spectrum.

Marine fungi showing multifunctional activity against human pathogenic microbes and cancer.

Multifunctional drugs have shown great promise in biomedicine. Organisms with antimicrobial and anticancer activity in combination with antioxidant activity need further research. The Red Sea and the Arabian Gulf coasts were randomly sampled to find fungi with multifunctional activity.

Desert soil fungi isolated from Saudi Arabia: cultivable fungal community and biochemical production.

Desert soils harbor fungi that have survived under highly stressed conditions of high temperature and little available moisture. This study was designed to survey the communities of cultivable fungi in the desert soils of the Arabian Peninsula and to screen the fungi for the potentially valuable antioxidants (flavonoids, phenols, saponins, steroids, tannins, terpenoids, and alkaloids) and enzymes (cellulase, laccase, lipase, protease, amylase, and chitinase). Desert soil was sampled at 30 localities representing different areas of Saudi Arabia and studied for physico-chemical soil properties.

Ecofriendly and low-cost synthesis of ZnO nanoparticles from Acremonium potronii for the photocatalytic degradation of azo dyes.

Nanoparticles (NPs) have enormous applications in every field of science by their particular size, diverse morphology, and higher surface-ratio, which provide them for unique properties. Nanosized materials can be used to overcome almost every challenge in science. The development of nanoscience, metal or metal oxide NPs have emerged as promising materials.

Bioremediation of ossein effluents using the filamentous marine cyanobacterium Cylindrospermum stagnale.

Wastewater containg proteinaceous ossein effluents are problematic to be treated. We studied the possibility to treat ossein effluents with the marine cyanobacterium strain Cylindrospermum stagnale. After optimizing the culture conditions of the bacterium, three different types of ossein effluents were tested: dicalcium phosphate (DCP), high total dissolved solids (HTDS) and low total dissolved (LTDS).

A review on metal-based nanoparticles and their toxicity to beneficial soil bacteria and fungi.

The unregulated deposition of metal-based nanoparticles in terrestrial ecosystems particularly in agricultural systems has alarmingly threatened the sustainability of the environment and diversity of beneficial microbial populations such as soil bacteria and fungi. This occurs due to the poor treatment of biosolids during wastewater treatment and their application in agricultural fields to enhance the fertility of soils. Continuous deposition, low biodegradability, and longer persistence of metal nanoparticles in soils adversely impact the population of soil beneficial bacteria and fungi.

Isolation, identification and bioactivity analysis of an endophytic fungus isolated from Aloe vera collected from Asir desert, Saudi Arabia.

Endophytic fungi isolated from desert plants are among the less known organisms with potentially valuable applications. The bioactivities of an endophytic fungus isolated from Aloe vera, a plant found in central regions of Asir desert, Saudi Arabia. Based on primary phytochemical screening, an efficient isolate was selected and identified according to the sequence analysis of the internal spacer regions ITS1, ITS4 and the 5.

Marine microorganisms as an untapped source of bioactive compounds.

The search for novel biologically active molecules has extended to the screening of organisms associated with less explored environments. In this sense, Oceans, which cover nearly the 67% of the globe, are interesting ecosystems characterized by a high biodiversity that is worth being explored. As such, marine microorganisms are highly interesting as promising sources of new bioactive compounds of potential value to humans.

A review on biogenic synthesis of metal nanoparticles using marine algae and its applications.

Marine algae have long been explored as food, feed, additives, drugs, and pesticides, yet now the framework is moving towards the algae mediated green synthesis of nanoparticles (NPs). This work is expanding step by step, like algae, are a rich origin of natural compounds. Recently, algae capped and stabilized NPs have picked up far and wide consideration as a less toxic, easy handling, cost effective, eco-friendly, usage in several science fields in nano size, safer to use, and greener method.

A Flow Injection Chemiluminescence Method for the Determination of Retinol in Pharmaceutical Formulations by Using Luminol-Diperiodatoargentate(III) Reaction.

In this paper, a chemiluminescence (CL) method is proposed for retinol determination by combining flow injection (FI) methodology. The CL reaction is based on the oxidation of luminol by diperiodatoargentate(III) (DPA) in the presence of retinol. Under the optimum conditions, the relative CL intensity was linear to the concentration of retinol over the range 5.
