Proton arc therapy plan optimization with energy layer pre-selection driven by organ at risk sparing and delivery time.

Objective: As proton arc therapy (PAT) approaches clinical implementation, optimizing treatment plans for this innovative delivery modality remains challenging, especially in addressing arc delivery time. Existing algorithms for minimizing delivery time are either optimal but computationally demanding or fast but at the expense of sacrificing many degrees of freedom. In this study, we introduce a flexible method for pre-selecting energy layers (EL) in PAT treatment planning before the actual robust spot weight optimization.

Social, Emotional, and Behavioral Functioning in Adolescents with Klinefelter Syndrome.

Objective: Klinefelter syndrome (KS) is a common genetic condition in males associated with an extra X chromosome (i.e., 47,XXY).

Meat intake in relation to composition and function of gut microbiota.

Objective: Meat intake is suggested to affect gut microbiome composition and the risk of chronic diseases. We aimed to identify meat-associated gut microbiome features and their association with host factors.

Design: Gut microbiota species were profiled by deep shotgun metagenomics sequencing in 9669 individuals.

Herpes Simplex Virus 1 Infection of Human Brain Organoids and Pancreatic Stem Cell-Islets Drives Organoid-Specific Transcripts Associated with Alzheimer's Disease and Autoimmune Diseases.

Viral infections leading to inflammation have been implicated in several common diseases, such as Alzheimer's disease (AD) and type 1 diabetes (T1D). Of note, herpes simplex virus 1 (HSV-1) has been reported to be associated with AD. We sought to identify the transcriptomic changes due to HSV-1 infection and anti-viral drug (acyclovir, ACV) treatment of HSV-1 infection in dissociated cells from human cerebral organoids (dcOrgs) versus stem cell-derived pancreatic islets (sc-islets) to gain potential biological insights into the relevance of HSV-1-induced inflammation in AD and T1D.

Clinical variability of across siblings.

Bardet-Biedl syndrome (BBS), an autosomal recessive ciliopathy with pleiotropic effects, manifests as a spectrum of anomalies involving multiple genes and affects fewer than 3,000 individuals in the USA. Due to its rarity and phenotypic variability, early diagnosis of BBS poses a significant challenge. Therefore, we aim to shed light on the intrafamilial phenotypic variation of BBS resulting from a variant by delineating the clinical presentation in two siblings.
