Intracardiac Teratoma in a Patient With Nonseminomatous Germ Cell Tumor.

This case report describes the management of a 30-year-old male patient with a history of an advanced nonseminomatous germ cell tumor, hip fracture complicated by extensive deep vein thrombosis and pulmonary embolism, and on apixaban presenting with asymptomatic intracardiac teratoma and abdominopelvic metastases. Multidisciplinary intervention, including successful surgical excision of the intracardiac mass, highlights the importance of coordinated care and vigilant follow-up in optimizing patient outcomes and preventing life-threatening complications.

Inhibitors of acetohydroxyacid synthase as promising agents against non-tuberculous mycobacterial diseases.

Acetohydroxyacid synthase (AHAS), exclusively present in microorganisms and plants, is a promising target for several herbicides due to its catalytic role in the branched-chain amino acid biosynthetic pathway. Previous studies have shown that K13787, a pyrazolopyrimidine sulfonamide AHAS inhibitor, was moderately effective against pulmonary infection caused by M. tuberculosis and nontuberculous mycobacteria (NTM).

Transgelin 2 guards T cell lipid metabolism and antitumour function.

Mounting effective immunity against pathogens and tumours relies on the successful metabolic programming of T cells by extracellular fatty acids. Fatty-acid-binding protein 5 (FABP5) has a key role in this process by coordinating the efficient import and trafficking of lipids that fuel mitochondrial respiration to sustain the bioenergetic requirements of protective CD8 T cells. However, the mechanisms that govern this immunometabolic axis remain unexplored.

High-grade serous ovarian cancer development and anti-PD-1 resistance is driven by IRE1α activity in neutrophils.

High-grade serious ovarian cancer (HGSOC) is an aggressive malignancy that remains refractory to current immunotherapies. While advanced stage disease has been extensively studied, the cellular and molecular mechanisms that promote early immune escape in HGSOC remain largely unexplored. Here, we report that primary HGSO tumors program neutrophils to inhibit T cell anti-tumor function by activating the endoplasmic reticulum (ER) stress sensor IRE1α.

Field efficacy of a recombinant toxoid vaccine against Shiga toxin 2e during a naturally occurring edema disease infection.

The objective of this field trial was to determine the efficacy of a recombinant toxoid vaccine against Shiga toxin 2e (Stx2e) in piglets suffering from edema disease (ED). Three farms with confirmed ED cases were selected for the field trials. On each farm, a total of 40 4-day-old pigs were randomly allocated to either the vaccinated or unvaccinated group, with 20 pigs per group (10 males and 10 females).
