Dandelion (Taraxacum officinale) Improves the Therapeutic Efficiency of Praziquantel in Experimental Schistosomiasis.

Purpose: Although praziquantel (PZQ) has a wide use as an anti-schistosome agent, many of its imperfections and side effects have been reported in many studies. The current study aims to evaluate the curative effect of a natural dandelion extract (Taraxacum officinale) on schistosomiasis either alone or in combination with PZQ based on parasitological, immunological, histopathological and molecular investigations.

Methods: Mice were experimentally infected with Schistosoma mansoni cercariae and then divided into four groups, Schistosoma spp.

Scalable nanoporous carbon films allow line-of-sight 3D atomic layer deposition of Pt: towards a new generation catalyst layer for PEM fuel cells.

Although nanoporous carbons are ubiquitous materials that are used in many clean energy and environmental applications, most are in powder form, thus requiring binders to hold particles together. This results in uncontrolled and complex pathways between particles, potentially exacerbating mass transport issues. To overcome these problems, we have developed an unprecedented binderless, self-supported, nanoporous carbon scaffold (NCS) with tunable and monodisperse pores (5-100+ nm), high surface area ( 200-575 m g), and 3-dimensional scalability (1-150+ cm, 1-1000 μm thickness).

A new myxozoan parasite, Myxobolus allami sp. n. (Myxozoa: Myxobolidae) from the intestinal wall of Sparidentex hasta (Valenciennes) in Arabian Gulf.

Myxobolus allami sp. n. is described from the intestinal wall of the silvery black porgy, Sparidentex hasta (Valenciennes), off Saudi Arabian coast of Arabian Gulf.

Wetting dynamics of nanoliter water droplets in nanoporous media.

Hypothesis: The Lucas-Washburn (L-W) equation is the classical theory to describe the dynamics of spontaneous imbibition in single micro-channels and micro-scale porous media. However, for nanoliter droplets imbibition in nanoporous media, the L-W equation may not be suitable, due to the nanoscale liquid-solid interactions, e.g.

Highly Ordered Nanoporous Carbon Scaffold with Controllable Wettability as the Microporous Layer for Fuel Cells.

We introduce a novel self-standing, nanoporous carbon scaffold (NCS, 25 μm thick), with an ordered inverse opal pore structure (∼85 nm pore) as a microporous layer (MPL) in a polymer electrolyte membrane fuel cell. Unlike previous studies, through chemical functionalization of the pore surfaces, the wettability of the MPL is controllably modified without altering the pore structure. environmental scanning electron microscopy experiments revealed water sorption in the hydrophilic NCS under moderate relative humidity (RH) conditions but not in the hydrophobic NCS, wherein water condensation on the surface was noted only at high RH.

The prevalence and intensity of external and internal parasites in working donkeys () in Egypt.

Aim: This study aims to record and update the prevalence and intensity of external and internal parasites in working donkeys () in Egypt during the period from January to December 2017.

Materials And Methods: A total of 120 donkeys (10 donkeys each month) were examined at Giza zoo abattoir through bimonthly visits. The examined donkeys were obtained from five governorates (Giza [20], Fayoum [40], Beni Suef [30], Monofia [20], and Assiut [10]).

Three cercariae from snail, Qarun Lake, Fayoum, Egypt.

Aim: The present study aims to focus on the role of common marine snails ( as a vector for some trematode parasites.

Materials And Methods: A total of 327 marine water snails were collected during the summer of 2016 from a Qarun lake in the EL-Fayoum Governorate, Egypt. The snails were investigated for infection by trematode parthenitae through induction of cercarial shedding by exposure to light and crushing the snails.
