State of nutrition amongst US college students: dataset of a national survey study

Abstract Objective This article presents the dataset titled “Nutrition habits amongst college students in the United States. [1]” The dataset contains the survey responses of 200 US college students aged 18–24 years regarding their knowledge, attitudes, and challenges with regard to nutrition. The recommended USDA (US daily allowance) is 200 calories, comprised of 2 cups fruits, 2.5 cups vegetables, 5.5 ounces of protein, 6 ounces of grains, and 3 cups of dairy [2]. Adhering to these nutritional guidelines however can be complicated by rising tuition prices, food insecurity, and inability to make one’s own food. Data description The data in the dataset attempt to estimate the incidence of these barriers. These data could be useful to understand the barriers to healthy eating amongst young adults, and design targeted solutions

Targeting multidrug resistant Mycobacterium tuberculosis htra2 with identical chemical entities of fluoroquinolones

Tuberculosis is a highly communicable and chronic respiratory disease caused by pathogenic bacterium Mycobacterium tuberculosis. The drug - resistant species of Mycobacterium tuberculosis are tough to cure due to its resistant activity toward potential drugs. Available inhibitors of tuberculosis include few antimicrobial fluoroquinolone agents like ciprofloxacin, ofloxacin, and moxifloxacin to treat resistant Mycobacterium strains. Literature study elucidates that macromolecular target namely, HtrA2 of Mycobacterium tuberculosis play a dual role of protease and chaperone. These two activities are dependent on temperature, with low temperatures promoting the chaperone function and high temperatures promoting serine protease activity. Under normal physiological conditions HtrA2 acts as a quality control factor and promotes cell survival. In the present investigation, we screened fluoroquinolone such as ciprofloxacin, moxifloxacin and ofloxacin and their analogues based on better Docking score, absorption, distribution, metabolism and excretion screening and Lipinski′s rule of 5, to find out their efficiency on resistant strain through in silico study. From the results observed, the analogues are suggested to be potent inhibitors of HtrA2 with sufficient scope for further exploration

Antibacterial Activity of Neem Extract and its Green Synthesized Silver Nanoparticles against Pseudomonas aeruginosa

Azadirachta indica, generally called as neem, margosa or Indian lilac is an Indian subcontinent native species, it ie well known for its various bioactivity In this study, neem leaves were collected and extracted. The extract was subjected for TLC and antibacterial activity against Pseudomonas aeruginosa. The extract was subjected for green synthesis of silver nanoparticles and it was able to reduce silver to silver nanoparticle of size around 65nm. The silver nanoparticle was also exhibiting antibacterial activity against P.aeruginosa

Evaluation of nanotoxicity of Araucaria heterophylla gum derived green synthesized silver nanoparticles on Eudrilus eugeniae and Danio rerio

Metal nanoparticles found its application in most fields because of its different physiochemical properties. Although there are several methods for synthesis of nanoparticles, where green and biological synthesis of nanoparticles reduces the toxicity. These metal nanoparticles are not properly disposed to the environment. Thus, this study was focussed to evaluate the effects of Araucaria heterophylla mediated green synthesised silver nanoparticles on various in vivo models such as earth worm—Eudrilus eugeniae and zebra fish—Danio rerio. Even the biologically synthesised nanoparticles were showing negative impacts on these models. Silver nanoparticles was found to cause epithelial erosion and lipofucshin deposits on Eudrilus eugeniae, where it was causing erosion and structure deformation in guts of Danio rerio

A study on influence of superparamagnetic iron oxide nanoparticles (SPIONs) on green gram (Vigna radiata L.) and earthworm (Eudrilus eugeniae L.)

Nanoparticles usage are now emerging as hazardous nanopollutants due to inappropriate usage and improper disposal. Superparamagnetic Iron Oxide Nanoparticles(SPIONs)is a widely used nanoparticle with various applications. In this study, SPIONs was evaluated for its impact against Vigna radiata and Eudrilus eugeniae. SPIONs were synthesized by chemical co-precipitation method in presence of cobalt chloride. The produced SPIONs was characterized using UV-Visible Spectroscopy, SEM (Scanning electron microscopy), EDX (Energy dispersive X-ray spectroscopy), XRD (X-ray diffraction), TEM (Transmission electron microscopy), AFM (Atomic force microscopy), XPS (X-ray photoelectron spectroscopy) and Zeta potential. The synthesized SPIONs were crystalline and monodispersed with size ranging between 15 nm and 20 nm. The seedlings of SPIONs treated Vigna radiatawere found to have reduced root and shoot growth. The bioaccumulation of iron oxide in the treated plants was confirmed by ICP-OES (Inductively coupled plasma - optical emission spectrometry) analysis and Prussian blue staining. Cellular destruction and reduced reproduction rate were found in SPIONs exposed Eudrilus eugeniae and ICP-OES analysis of earthworm samples affirmed the bioaccumulation of SPIONs
