In order to assess the prevalence of target organ damage 78 men with borderline hypertension, according to the World Health Organization criteria, and 67 normotensive controls underwent echocardiographic, electrocardiographic and fundoscopic examination, followed by ambulatory blood pressure monitoring for 24 hours. Echocardiographic left ventricular hypertrophy was found in 13 borderline hypertensive subjects (16.6%), while no electrocardiographic or fundoscopic abnormalities could be detected. Our data suggest that noninvasive assessment of cardiovascular status, including echocardiography, allows recognition of a subset of borderline subjects with an increased risk for subsequent cardiac morbid events, thereby improving prognostic stratification.

Whole-body PET imaging of simian immunodeficiency virus using gp120-targeting probes fails to reveal regions of specific uptake in rhesus macaques.

Purpose: Following the initial reports demonstrating the feasibility of immunoPET imaging of simian immunodeficiency virus (SIV) using gp120-targeting monoclonal antibodies in non-human primates, replication efforts of the imaging system in human immunodeficiency virus (HIV)-infected individuals have yielded conflicting results. Herein, we used two anti-gp120 antibodies, 7D3 and ITS103.01LS-F(ab'), to interrogate the reproducibility of gp120-targeting probes for immunoPET imaging of SIV in rhesus macaques.

Background: Liver cirrhosis represents a critical stage of chronic liver disease, characterized by progressive liver damage, cellular dysfunction, and disrupted cell-to-cell interactions. Glycosylation, an essential post-translational modification, significantly influences cellular behavior and disease progression. Its role in cirrhosis at the single-cell level remains unclear, despite its importance.

Antibiotic-resistant bacteria often cause lethal infections in both the surficial and deep organs of humans. Failure of antibiotics in resistant infections leads to more effective alternative therapies, like spatiotemporally controllable piezodynamic therapy (PZDT) with deep penetration. Currently, PZDT demands further investigation for improved treatment outcomes and the corresponding therapeutic mechanisms.

Background: Proton pencil beam scanning (PBS) treatment planning for head and neck (H&N) cancers is a time-consuming and experience-demanding task where a large number of potentially conflicting planning objectives are involved. Deep reinforcement learning (DRL) has recently been introduced to the planning processes of intensity-modulated radiation therapy (IMRT) and brachytherapy for prostate, lung, and cervical cancers. However, existing DRL planning models are built upon the Q-learning framework and rely on weighted linear combinations of clinical metrics for reward calculation.

Sepsis-induced immunosuppression is related to increased susceptibility to secondary infections and death. Lung is the most vulnerable target organ in sepsis, but the understanding of the pulmonary immunosuppression state is still limited. Here, single-cell RNA sequencing of bronchoalveolar lavage fluid (BALF) is performed to map the landscape of immune cells, revealing a neutrophil-driven immunosuppressive program in the lungs of patients with immunosuppressive sepsis.
