Purpose: The present experimental study seeks to evaluate the in vitro and in vivo effects, as well as the potential mechanisms of action, of Rhanterium epapposum essential oil (REE) and its main constituents against Giardia lamblia infection.

Methods: The analysis of REE was performed using the Gas Chromatography-Mass Spectrometry (GC-MS) detector. The in vitro effects of REE and its main constituents on viability of G.

A new series of thieno[2,3-][1,2,4]triazolo[1,5-]pyrimidines was designed and synthesized using readily available starting materials, specifically, -enaminoester. Their cytotoxicity was screened against three cancer cell lines, namely, MCF-7, HCT-116, and PC-3. 2-(4-bromophenyl)triazole and 2-(anthracen-9-yl)triazole afforded excellent potency against MCF-7 cell lines (IC = 19.

Background: Doxorubicin (DOX), an anthracycline antibiotic, is a powerful chemotherapeutic agent effective against multiple types of cancer, particularly lung, breast, bladder and hematologic neoplasia (lymphomas and leukemia). However, its therapeutic usage is restricted by its known cardiotoxicity, which is associated with the production of oxidative stress. Enhancing antioxidant capacity represents a promising approach to mitigate DOX-induced cardiotoxicity.

Background: Dogs can act as reservoirs of canine leishmaniasis, caused by species. The aims of this study were to determine the prevalence of canine leishmaniasis using a PCR technique among stray dogs living in three provinces of Saudi Arabia, Riyadh, Al-Ahsa Oasis and Al-Qaseem, where the disease is endemic; and to identify and document different to species levels.

Methods: This cross-sectional investigation was conducted, from Mar 2016 to Apr 2018, in three parts of Saudi Arabia: Central province (Riyadh), Eastern province (Al-Ahsa Oasis) and Al-Qaseem province.

Article Synopsis
  • In Saudi Arabia, there has been increasing resistance of Parascaris spp. to common anthelmintics like ivermectin, abamectin, and fenbendazole over the past decade.
  • A study examined 341 foals and revealed that 53% were infected, with the highest resistance recorded for fenbendazole in 55% of farms, followed by ivermectin in 27% of farms.
  • The findings highlight significant concerns regarding anthelmintic-resistant Parascaris spp. in horses, suggesting a need for improved management strategies on these farms.

Translin and Trax proteins are highly conserved nucleic acid binding proteins that have been implicated in RNA regulation in a range of biological processes including tRNA processing, RNA interference, microRNA degradation during oncogenesis, spermatogenesis and neuronal regulation. Here, we explore the function of this paralogue pair of proteins in the fission yeast. Using transcript analysis we demonstrate a reciprocal mechanism for control of telomere-associated transcripts.

Cadmium (Cd) is the most prevalent toxic metal present in livestock feed; therefore, the present study aimed to examine the ameliorative effects of grape seed extract (GSE) on cadmium chloride (CdCl2)‑induced testicular dysfunction of Wistar rats. Male adult Wistar rats (40 rats; n=10/group) were divided into four equal groups. Group one was used as a control, and was given ad libitum access to food and water.

Tobacco smoking represents major national and international health hazard that interferes with wide range of physiological functions and biomarkers. In the current study we have investigated the influence of tobacco smoking on some biological markers such as serum amyloid protein-A, rheumatoid factor, serum glucose level and lipid profile in Saudi population. The fore mentioned parameters were investigated in a total of 275 cases in 3 different age categories (less than 20 years old, 20-40 years old and older than 40 years old).
