Atherosclerosis (AS) formation is enhanced by different mechanisms including cytokine generation, vascular smooth muscle cell proliferation, and migration. One of the recent treatments towards endothelial dysfunction and AS is Vinpocetine (VPN). VPN is a potent inhibitor of phosphodiesterase enzyme 1 (PDE-1) and has anti-inflammatory and antioxidant effects through inhibition the expression of nuclear factor kappa B (NF-κB).

Albendazole is the most common benzimidazole derivative used for trichinellosis treatment but has many drawbacks. The quest for alternative compounds is, therefore, a target for researchers. This work aims to assess the in vitro anthelmintic effect of nifedipine, a calcium channel blocker, and a methanol extract of the flowers of Chrysanthemum coronarium as therapeutic repurposed drugs for treating different developmental stages of Trichinella spiralis in comparison with the reference drug, albendazole.

Background: and are among the most common intestinal protozoa worldwide. Treatment of infection by metronidazole (MTZ) has some limitations. The objective of this study was to detect the prevalence of and among school-age children from December 2021 till March 2022 from Motoubes, Kafrelsheikh, Egypt, and determine the efficacy of nitazoxanide (NTZ), NTZ plus garlic and tinidazole (TIN) on and giardiasis infection.

Helminths are metazoan parasites affecting about one third of the worldwide population. Chronic helminth infections (CHIs) confer immunological tolerance to harmless and self-antigens mediated by regulatory T cells (Treg) that are up-regulated. In coronavirus disease 2019 (COVID-19), abnormal adaptive immune response and unrestrained innate immune response could result in local and systemic immune-mediated tissue damage.

Objective: Lactoferrin is an 80 KDa iron-binding glycoprotein that plays a significant role in the innate immune system and is considered to be an important microbicide molecule. This study aimed to assess the concentration of lactoferrin in Schistosoma mansoni-infected cases before and after praziquantel treatment.

Methods: A cross-sectional study was carried out on 250 individuals aged from 5 to 30 years.

Background: In certain settings, the prevalence and severity of schistosoma infection do not lessen despite repeated rounds of preventative chemotherapy; these areas are known as hotspots. This study aimed to investigate the role of human practices, besides environmental and malacological factors, in the maintenance of the Schistosoma mansoni infection transmission chain in hotspot areas in Egypt.

Methods: This cross-sectional study was conducted between July and November 2019 in Kafr El-Sheikh Governorate, Egypt.

is one of the less well-understood waterborne protozoa of medical and veterinary importance. The present study aimed to detect, identify, and subtype in cattle and humans in northern Egypt and to investigate the potential for zoonotic transmission. Fecal samples were collected from 136 humans (68 in contact with animals and 68 no animal contact) and 190 cattle from a rural area in Kafr El-Sheikh Province, Egypt.

The epidemic of the novel coronavirus disease (COVID-19) that started in 2019 has evoked an urgent demand for finding new potential therapeutic agents. In this study, we performed a molecular docking of anti-HIV drugs to refine HIV protease inhibitors and nucleotide analogues to target COVID-19. The evaluation was based on docking scores calculated by AutoDock Vina and top binding poses were analyzed.

Our objective was to study the prevalence of intestinal parasitic infections among humans and their contact livestock animals in a rural community in Gharbia governorate, Egypt. The collected human and livestock animal fecal samples were examined by formol ether sedimentation technique and modified Ziehl-Neelsen stain. Human samples were further examined by the Kato-Katz technique.

Article Synopsis
  • Asymptomatic leishmaniasis significantly contributes to the ongoing transmission of Leishmania within endemic communities, complicating efforts to eliminate the disease.
  • A systematic review and meta-analysis of 111 articles found an overall prevalence of 11.2% for asymptomatic leishmaniasis in the general population, with higher rates (36.7%) in those living with symptomatic patients.
  • The study revealed that 64.9% of individuals with leishmaniasis were asymptomatic, and males were more likely to develop symptoms, with a notable prevalence remaining stable over the past 40 years.

The study aimed to compare the diagnostic performance of the Kato-Katz, formalin ether concentration method (FECM) and FLOTAC using Sheather's sugar solution (FS1), saturated sodium chloride (FS2) and zinc sulfate (FS7) for the diagnosis of intestinal parasites among school children, focusing on Schistosoma mansoni. Ninety fecal samples were examined using the above mentioned techniques. The overall infection rate was 87.
