Salinity impacts on humidification dehumidification (HDH) desalination systems: review.

The use of humidification-dehumidification water desalination technology has been shown to be a practical means of meeting the demand for freshwater. The aim of this review is to investigate the impact of salinity on HDH techniques that have various benefits in terms of both economics and the environment, including the capacity to operate at low temperatures, utilize sustainable energy sources, the need for low maintenance, and straightforward construction requirements. Also, in this review, it is observed that the HDH system's components are strong and capable of treating severely salinized water.

Screening Fungal Endophytes Derived from Under-Explored Egyptian Marine Habitats for Antimicrobial and Antioxidant Properties in Factionalised Textiles.

Marine endophytic fungi from under-explored locations are a promising source for the discovery of new bioactivities. Different endophytic fungi were isolated from plants and marine organisms collected from Wadi El-Natrun saline lakes and the Red Sea near Hurghada, Egypt. The isolated strains were grown on three different media, and their ethyl acetate crude extracts were evaluated for their antimicrobial activity against a panel of pathogenic bacteria and fungi as well as their antioxidant properties.

Environmentally sound approach for imparting antibacterial and UV-protection functionalities to linen cellulose using ascorbic acid.

In this work, multifunctional linen cellulose fabrics were facilely developed by using an eco-friendly finishing formulations and the pad-dry/microwave fixation technique. Both reactant resin and citric acid have been employed as low- and zero-formaldehyde crosslinkers along with their proper catalyzing agents. Individual incorporation of ascorbic acid and selected phenolic compounds namely salicylic acid, resorcinol, and gallic acid, as natural active ingredient (AI-OH) along with PEG-400 or modified nonionic silicone-softener in ether- or ester-crosslinking formulation and their impacts on the performance, functional properties and degree of coloration of the finished fabrics were investigated.

Green options for imparting antibacterial functionality to cotton fabrics.

This study demonstrated that antibacterial cellulosic textiles can be fabricated in eco-friendly manner by grafting of monochlorotriazinyl β-cyclodextin (MCT-βCD) onto knitted and woven cotton fabrics followed by post-loading of any of the green active ingredients namely Rosemary oil, Lavender oil, Clove oil, Cinnamon oil, Aloe vera gel, Vanillin, Ag-ions, Natural Yellow 7 and Natural Red 25 dyes into the hydrophobic cavities of grafted β-CD moieties. Some of the grafted, post-loaded fabric samples were characterized by FTIR, SEM, and EDS analysis. The enhancement in the imparted antibacterial functionality as well as durability to wash are governed by type of cellulosic substrate, kind, chemistry, antibacterial activity as well as extent of inclusion and subsequent release of the hosted bioactive agent.

Loading of chitosan - Nano metal oxide hybrids onto cotton/polyester fabrics to impart permanent and effective multifunctions.

New and durable multifunctional properties of cotton/polyester blended fabrics were developed through loading of chitosan (Cs) and various metal oxide nanoparticles (MONPs) namely ZnO, TiO, and SiO onto fabric surface using citric acid/Sodium hypophosphite for ester-crosslinking and creating new anchoring and binding sites, COOH groups, onto the ester-crosslinked fabrics surface. The surface morphology and the presence of active ingredients (Cs & MONPs) onto selected - coated fabric samples were analyzed by SEM images and confirmed by EDS spectrums. The influence of various finishing formulations on some performance and functional properties such as wettability, antibacterial activity, UV-protection, self-cleaning, resiliency and durability to wash were studied.

Retraction note to: The effect of lead acetate toxicity on experimental male albino rat.

Retraction to: Biol Trace Elem Res 144(1–3):1120–1132, DOI 10.1007/s12011-011-9149-z. Article has been retracted due to duplicate publication.

Effect of lead acetate toxicity on experimental male albino rat.

Objective: To evaluate the effect of different doses of lead acetate (1/20, 1/40 and 1/60 of LD50) on body weight gain, blood picture, plasma protein profile and the function of liver, kidney and thyroid gland.

Methods: Male albino rats were divided into four groups, the first group represented the health control animals, while the second, third and fourth groups were ingested orally with sub lethal doses of lead acetate (1/20, 1/40 and 1/60) of the oral LD50, respectively. One dose was ingested every two days during the experimental period (14 weeks) including the adaptation time.

The effect of lead acetate toxicity on experimental male albino rat.

The toxic effect of Pb ion (lead acetate) was investigated using male albino rats, which was ingested at 1/20, 1/40, and 1/60 sublethal doses. Relative to normal control, the ingestion of Pb(2+) induced significant stimulation in ALT and AST activity. In addition, total soluble protein and albumin contents of plasma were decreased, while the content of globulin was changed by the Pb(2+) treatments.

Parathyroid hormone-related protein (PTHrP) expression in ameloblastoma.

Objective: Parathyroid hormone-related protein (PTHrP) production has been demonstrated in a variety of tumor subtypes. Local production of PTHrP by metastatic tumor cells in bone has been linked to bone destruction and tumor growth. Ameloblastoma (AB) is a relatively common odontogenic epithelial neoplasm that manifests local infiltrative intraosseous growth.

An analysis of provider attitudes toward end-of-life decision-making.

The explosion of technological and biomedical interventions over the past half century appears to have enhanced the medical profession's ability to prolong life at a faster pace than society's ability to develop comprehensive bioethical laws governing end-of-life decisions. This study was conducted to determine if there was a correlation between educational and occupational backgrounds and participants' perceptions of end-of-life care. Study participants came from various areas and levels of healthcare at a large federal healthcare facility and included nurses, doctors, pharmacists, dietitians, administrators, and others.
