Sesame, L., is one of the oldest domesticated crops used for its oil and protein in many parts of the world. To build genomic resources for sesame that could be used to improve sesame productivity and responses to stresses, a USDA sesame germplasm collection of 501 accessions originating from 36 countries was used in this study.

has received considerable attention as a renewable biofuel crop for semi-arid zones due to its high oil content and polyunsaturated fatty acids contents. It is important to develop new drought-resistant cultivars of production to expand its areas into more arid regions. The accumulation of leaf cuticular wax on plant surfaces is one mechanism that reduces non-stomatal water loss, thus increasing drought resistance in plants.

Article Synopsis
  • The study explored using Hirudo medicinalis to discover new treatments for murine coccidiosis caused by Eimeria papillate.
  • Researchers separated hirudo extract antigens into different fractions and tested them, finding that some significantly reduced parasite output while enhancing goblet cell counts and MUC2 gene expression.
  • The most effective protein identified in the fractions was Eglin C, which displayed potential as a therapeutic or anti-inflammatory agent against coccidiosis infections, though higher concentrations negatively impacted lymphocyte activity.

Eimeriosis is a common parasitic disease in the chicken industry. The aim of this study was to assess the protective role of Hirudo extract antigens (HEA) against murine eimeriosis induced by Eimeria papillate. The oocyst output, developmental stages, goblet cells and oxidative stress, were investigated.

Introduction: After hepatocellular carcinoma (HCC) interventional therapies, noninvasive vascular diagnostic imaging [duplex, Color/power Doppler ultrasonography, and triphasic computed tomography (CT)] determines the lesion complete/incomplete ablation. The aim was to analyze the usefulness of duplex, color/power Doppler ultrasonography in HCC ablation after percutaneous ablative therapies (PATs).

Methods: We included 30 patients with 33 HCCs subjected to duplex/Doppler ultrasonography, ultrasound-guided fine-needle aspiration cytology (FNAC), and triphasic CT, all these before and after PATs.

Between June 2016 and June 2019, we surveyed 62 Mediterranean geckos, Hemidactylus turcicus, from Abu Rawash, Giza, Egypt, for the presence of endoparasites. In June 2016, we found 3 individuals to be infected with Eimeria lineri. We studied the morphology and inner structures of its sporulated oocysts, and the locations of its intestinal endogenous stages.

Background: Coccidiosis is an intestinal disease caused by protozoan parasites of the genus Eimeria and responsible for considerable economic loss in the livestock and poultry industries. Resistance to the current anticoccidial drugs is now a major challenge to efforts to control the disease, and this has stimulated the search for new compounds as alternative treatments. In this context, plant extracts have emerged as an alternative and complementary approach to control coccidiosis.

Nitrogen (N) plays a key role in plants because it is a major component of RuBisCO and chlorophyll. Hence, N is central to both the dark and light reactions of photosynthesis. Genotypic variation in canopy greenness provides insights into the variation of N and chlorophyll concentration, photosynthesis rates, and N fixation in legumes.

Background And Aims: This study aimed to assess the safety and efficacy of sofosbuvir (SOF)-based regimens in patients with moderate to severe renal impairment; a subject which has been questioned by many investigators with conflicting results.

Methods: This is a real-life multicentre retrospective cohort study on 4944 chronic Hepatitis C virus (HCV) patients with chronic kidney disease (CKD) (eGFR <60 mL/min/1.73 m ) who received SOF-based therapy in specialized treatment centres affiliated to the National Committee for the Control of Viral Hepatitis in Egypt.

Hepatozoon aegypti Bashtar, Boulos & Mehlhorn, 1984 was first described from the blood of the diadem snake (Spalerosophis diadema) in Egypt. During an investigation of the diversity of reptilian haemogregarines in Saudi Arabia, seven diadem snakes (100% of the sample) were found to be highly parasitised by H. aegypti, with an average parasitaemia of 37% per 500 counted erythrocytes.
