Double Deletion of EP402R and EP153R in the Attenuated Lv17/WB/Rie1 African Swine Fever Virus (ASFV) Enhances Safety, Provides DIVA Compatibility, and Confers Complete Protection Against a Genotype II Virulent Strain.

African swine fever virus (ASFV) is a devastating disease affecting domestic and wild suids and causing significant economic losses in the global pig industry. Attenuated modified live virus (MLV) vaccines are the most promising approaches for vaccine development. This study aimed to evaluate the safety and efficacy of four recombinant ASFV genotype II strains, derived from the non-hemadsorbing (non-HAD) attenuated isolate Lv17/WB/Rie1, through the single or simultaneous deletion of virulence-associated genes.

Asynchronous Transitions from Hepatoblastoma to Carcinoma in High-Risk Pediatric Tumors.

Most malignant hepatocellular tumors in children are classified as either hepatoblastoma (HB) or hepatocellular carcinoma (HCC), but some tumors demonstrate features of both HB and HCC . These tumors have been recognized under a provisional diagnostic category by the World Health Organization and are distinguished from HB and HCC by a combination of histological, immunohistochemical, and molecular features . Their outcomes and cellular composition remain an open question .

The impact of hypoalbuminemia on the long-term prognosis of patients with acute heart failure: The modifying role of carbohydrate antigen 125.

Aims: Hypoalbuminemia is frequently found in patients with heart failure (HF), associated with higher morbimortality in acute HF (AHF). Moreover, Carbohydrate Antigen 125 (CA125) is elevated in most of the AHF patients. In this cohort of patients admitted for AHF, our objective was to evaluate the association between hypoalbuminemia and long-term outcomes, including mortality and HF readmissions, stratified by CA125 concentration.

Initial antigen encounter determines robust T-cell immunity against SARS-CoV-2 BA.2.86 variant three years later.

Objectives: We aimed to evaluate the adaptive immune responses' cross-recognition of the hypermutated SARS-CoV-2 BA.2.86 variant and identify the determinants influencing this recognition.

Ionic Crosslinking of Linear Polyethyleneimine Hydrogels with Tripolyphosphate.

In this work, the mechanical properties of hydrogels based on linear polyethyleneimine (PEI) chemically crosslinked with ethyleneglycoldiglycidyl ether (EGDE) were improved by the ionic crosslinking with sodium tripolyphosphate (TPP). To this end, the quaternization of the nitrogen atoms present in the PEI structure was conducted to render a network with a permanent positive charge to interact with the negative charges of TPP. The co-crosslinking process was studied by H high-resolution magic angle spinning (H HRMAS) NMR and X-ray photoelectron spectroscopy (XPS) in combination with organic elemental analysis and inductively coupled plasma mass spectrometry (ICP-MS).
