Appraisal of potentially toxic metals contamination in protein supplements for muscle growth: A chemometric approach and associated human health risks.

Background: The use of protein supplements by athletes has risen due to their effectiveness in meeting dietary needs. However, there is a growing concern about the presence of potentially toxic metals (PTMs. Al, Cr, Mn, Ni, Cu, Zn, Cd, and Pb) in these supplements.

Garlic and ginger essential oil-based neomycin nano-emulsions as effective and accelerated treatment for skin wounds' healing and inflammation: and studies.

Skin, largest organ of human, is directly exposed to environment and hence is prone to high rates of injuries and microbial infections. Over the passage of time these microbes have developed resistance to antibiotics making them ineffective especially in lower doses and hence, higher dosages or new drugs are required. The current study deals with designing of nano-emulsion (NE) formulations composed of garlic and ginger oils (0.

N-Sulfonated derivatives of (2-furoyl)piperazine: Promising antibacterial agents with mild cytotoxicity.

2-Furoyl-1-piperazine (1) was treated with a series of alkyl/aryl sulfonyl chlorides (2a-i) under benignant conditions to obtain its N-sulfonated derivatives (3a-i). These compounds were screened for their antibacterial potential against pathogenic bacteria. The low Minimum Inhibitory Concentration (MIC) values of these molecules, in comparison of ciprofloxacin, demonstrated their high antibacterial potential.

Synthesis of novel N-(2,3-dihydro-1,4-benzodioxin-6-yl)-2-{[5-(un/substituted-phenyl)-1,3,4-oxadiazol-2-yl]sulfanyl}acetamides as potent antibacterial agents.

The synthetic methodology was initiated by reacting 1,4-benzodioxane-6-amine (1) with 2-bromoacetyl bromide (2) in aqueous alkaline media under dynamic pH control to get compound 2,3-dihydro-1,4-benzodioxin-6-yl-2-bromoacetamide (3). In the subsequent reactions, a variety of un/substituted-benzoic acids (4a-k), through a succession of three steps, was converted into respective oxadiazole nucleophiles, 7a-k. Finally, the targeted molecules, 8a-k, were obtained by reacting 7a-k with electrophile 3 in an aprotic polar solvent.

Synthesis of gold and silver nanoparticles by use of arabinoglucan from Lallemantia royleana.

Highly stable gold and silver nanoparticles were synthesized by use of an arabinoglucan from Lallemantia royleana seeds without additional use of reducing or stabilizing agents. The mechanism involved the reduction potential of the hemicellulose as verified by cyclic voltammetry. The arabinoglucan used was substantially free from ferulic acid and phenolic content, suggesting the inherent reducing potential of arabinoglucan for gold and silver ions.

REPORT - Synthesis of promising antibacterial and antifungal agents: 2-[[(4-Chlorophenyl)sulfonyl](2,3-dihydro-1,4-benzodioxin-6-yl)amino]-N-(un/substituted-phenyl)acetamides.

In the presented work, 2,3-dihydro-1,4-benzodioxin-6-amine (1) was reacted with 4-chlorobenzenesulfonyl chloride (2) in presence of aqueous basic aqueous medium to obtain 4-chloro-N-(2,3-dihydro-1,4-benzodioxin-6-yl)benzenesulfonamide (3). In parallel, various un/substituted anilines (4a-l) were treated with bromoacetyl bromide (5) in basified aqueous medium to obtain corresponding 2-bromo-N-(un/substituted)phenylacetamides (6a-l) as electrophiles. Then the compound 3 was finally reacted with these electrophiles, 6a-l, in dimethylformamide (DMF) as solvent and lithium hydride as base and activator to synthesize a variety of 2-[[(4-chlorophenyl)sulfonyl](2,3-dihydro-1,4-benzodioxin-6-yl)amino]-N-(un/substituted)phenylacetamides (7a-l).

Pharmaco-Technical Evaluation of Statistically Formulated and Optimized Dual Drug-Loaded Silica Nanoparticles for Improved Antifungal Efficacy and Wound Healing.

The current research aimed at designing mesoporous silica nanoparticles (MSNs) for a controlled coadministration of salicylic acid (SA) and ketoconazole (KCZ) to effectively treat highly resistant fungal infections. The sol-gel method was used to formulate MSNs, which were further optimized using central composite rotatable design (CCRD) by investigating mathematical impact of independent formulation variables such as pH, stirring time, and stirring speed on dependent variables entrapment efficiency (EE) and drug release. The selected optimized MSNs and pure drugs were subjected to comparative antifungal studies, skin irritation, cytotoxicity, and histopathological evaluations.

Synthesis, spectral characterization and antimicrobial studies of novel series of allylidene based multifaceted chalcones analogues.

Following the Claisen Schmidt condensation a series of chalcone, their allylidene derivatives and metallic complexes were produced and subsequently screened for antibacterial assay. The precursors were simple acetophenone and different substituted aryl benzaldehydes; which were made to react in basic ethanolic conditions. The structure of synthesized targets was established by IR, 1H-NMR and EIMS data.

In vitro assessment of antibacterial, antifungal, enzyme inhibition and hemolytic activities of various fractions of Rhynchosia pseudo-cajan.

The aims of the present investigation were to assess the antibacterial, antifungal, enzyme inhibition and hemolytic activities of various fractions of Rhynchosia pseudo-cajan Cambess. The methanolic extract of the plant was dissolved in the water (distilled) and then partitioned with the n-hexane, chloroform, EtOAc and n-BuOH sequentially. Antibacterial activity was checked against Escherichia coli, Pasturella multocida, Bacillus subtilis and Staphylococcus aureus by the disc diffusion method using streptomycin sulphate, a standard antibiotic, as positive control.

Quadratic trigonometric B-spline for image interpolation using GA.

In this article, a new quadratic trigonometric B-spline with control parameters is constructed to address the problems related to two dimensional digital image interpolation. The newly constructed spline is then used to design an image interpolation scheme together with one of the soft computing techniques named as Genetic Algorithm (GA). The idea of GA has been formed to optimize the control parameters in the description of newly constructed spline.
