Severe combined immunodeficiency disease (SCID), characterized by profound immune system dysfunction, can lead to life-threatening infections and death. Animal models play a pivotal role in elucidating biological processes and advancing therapeutic strategies. Recent advances in gene-editing technologies, including zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), CRISPR/Cas9, and base editing, have significantly enhanced the generation of SCID models.

DNA2, a multifunctional enzyme with structure-specific nuclease, 5 -to-3 helicase, and DNA-dependent ATPase activities, plays a pivotal role in the cellular response to DNA damage. However, its involvement in cerebral ischemia/reperfusion (I/R) injury remains to be elucidated. This study investigated the involvement of DNA2 in cerebral I/R injury using conditional knockout (cKO) mice ( -Cre) subjected to middle cerebral artery occlusion (MCAO), an established model of cerebral I/R.

The effect of physical cues on platelet storage lesion.

Hematology

December 2025

Department of Blood Transfusion, First Affiliated Hospital, Third Military Medical University (Army Medical University), Chongqing, People's Republic of China.

Background: Platelet concentrates play an important role in clinical treatment such as platelet function disorders and thrombocytopenia. In the process of preparation and storage of platelets, centrifugation, leukofiltration, and agitation will cause morphological changes and impaired function of platelets, which is associated with the increase of platelet transfusion refractoriness, and named as platelet storage lesion (PSL).

Method: This paper proposes three major operations (centrifugation, agitation, and leukofiltration) that platelets experience during the preparation and storage process, to explore the effect of physical cues on PSL.

Although the association between dementia such as Alzheimer's disease and traumatic brain injury (TBI) is well established, there are significant knowledge gaps with respect to the perspective of dementia and epilepsy without TBI. We aimed to investigate the relationship between dementia and epilepsy in a population-based study of patients without history of TBI. This study included a random sample of 30,715 patients with no history of TBI, including 6143 with epilepsy as the study cohort and 24,572 without epilepsy as the comparison cohort.

NEDD4-Mediated GSNOR Degradation Aggravates Cardiac Hypertrophy and Dysfunction.

Circ Res

January 2025

Key Laboratory of Drug Targets and Translational Medicine for Cardio-cerebrovascular Diseases, Key Laboratory of Targeted Intervention of Cardiovascular Disease, Collaborative Innovation Center for Cardiovascular Disease Translational Medicine, The Affiliated Suzhou Hospital of Nanjing Medical University, Suzhou Municipal Hospital, Gusu School, Nanjing Medical University, Jiangsu, China (X.T., X.L., X.S., Y. Zhang, Y. Zu, Q.F., L.H., S.S., F.C., L.X., Y.J.).

Background: The decrease in S-nitrosoglutathione reductase (GSNOR) leads to an elevation of S-nitrosylation, thereby exacerbating the progression of cardiomyopathy in response to hemodynamic stress. However, the mechanisms under GSNOR decrease remain unclear. Here, we identify NEDD4 (neuronal precursor cell expressed developmentally downregulated 4) as a novel molecule that plays a crucial role in the pathogenesis of pressure overload-induced cardiac hypertrophy, by modulating GSNOR levels, thereby demonstrating significant therapeutic potential.

Objectives: Physical function in RA is largely influenced by multiple clinical factors, however, there is a growing body of evidence that psychological state and other comorbidities also play an essential role. Using data obtained in the COVID-19 Vaccination in Autoimmune Diseases study, an international self-reported e-survey, we aimed to explore the predictive ability of sociodemographic and clinical variables on Patient-Reported Outcomes Measurement Information System Physical Function Short Form 10a (PROMIS PF-10a) in RA and to investigate variation in disease activity and functional outcomes based on country-level socio-economic parameters.

Methods: Patient demographics, disease characteristics including current symptom status, functional status and treatment variables, as well as income level of the country of residence, were extracted from survey responses.

Background And Aims: Hematopoietic stem cell transplantation (HSCT) is a key therapeutic approach for pediatric patients with hematologic and non-hematologic disorders. However, post-transplant pulmonary complications remain a significant cause of morbidity and mortality. Pulmonary Function Tests (PFTs) are essential for the early detection of pulmonary dysfunction, yet their application in pediatric HSCT recipients has yielded inconsistent results.

Background And Aims: Non-Alcoholic Steatohepatitis (NASH), a severe form of Non-Alcoholic Fatty Liver Disease (NAFLD), is characterized by inflammation and fibrosis in the liver, often progressing to cirrhosis and hepatocellular carcinoma. Despite its rising prevalence and significant disease burden, effective pharmacological treatments have been limited to lifestyle modifications and surgical interventions. Recently, resmetirom, a thyroid hormone receptor-β agonist, received FDA approval for treating NASH, offering new hope to patients.
