Toxoplasmosis is a significant food-borne protozoal disease in humans and animals. The study aimed to find out Toxoplasma seropositivity in sheep, estimate epidemiological risk factors and assess haemato-biochemical parameter changes. Blood samples were collected from 276 indigenous sheep in five districts surrounding Sulaymaniyah Province in the northern region of Iraq.

Immunogenic cell death (ICD) offers a promising avenue for the treatment of triple-negative breast cancer (TNBC). However, optimizing immune responses remains a formidable challenge. This study presents the design of RBCm@Pt-CoNi layered double hydroxide (RmPLH), an innovative sonosensitizer for sonodynamic therapy (SDT), aimed at enhancing the efficacy of programmed cell death protein 1 (PD-1) inhibitors by inducing robust ICD responses.

Polyunsaturated fatty acids (PUFAs) including omega-3 and omega-6 are obtained from diet and can be measured objectively in plasma or red blood cells (RBCs) membrane biomarkers, representing different dietary exposure windows. In vivo conversion of omega-3 and omega-6 PUFAs from short- to long-chain counterparts occurs via a shared metabolic pathway involving fatty acid desaturases and elongase. This analysis leveraged genome-wide association study (GWAS) summary statistics for RBC and plasma PUFAs, along with expression quantitative trait loci (eQTL) to estimate tissue-specific genetically predicted gene expression effects for delta-5 desaturase (FADS1), delta-6 desaturase (FADS2), and elongase (ELOVL2) on changes in RBC and plasma biomarkers.

Severe valproic acid (VPA) overdose is characterized by coma (sometimes with cerebral oedema), respiratory depression, hypotension and metabolic abnormalities. Traditional management of VPA poisoning has been limited to gastrointestinal decontamination, L-carnitine supplementation and, in severe cases, haemodialysis. Recently, interest has developed in the use of carbapenem antibiotics as an adjunctive therapy in patients with severe VPA poisoning.

A sustained blood-stage infection of the human malaria parasite P. falciparum relies on the active exit of merozoites from their host erythrocytes. During this process, named egress, the infected red blood cell undergoes sequential morphological events: the rounding-up of the surrounding parasitophorous vacuole, the disruption of the vacuole membrane and finally the rupture of the red blood cell membrane.
