Solitary Langerhans cell histiocytosis of the sternum in a 21‐year‐old woman

Clinical Case Reports
Key Clinical Message Children are more likely to develop Langerhans cell histiocytosis (LCH), a rare disorder with an unknown cause. LCH often invades skeletal systems, while it has occasionally been seen in the sternum or ribs.

Biosilicification in monocots: Comparative analysis highlights contrasting patterns of deposition

American Journal of Botany, EarlyView.
Abstract Premise New insights into biomineral uptake and sequestration are important for understanding how plants grow. Some plants accumulate silica accretions in precise locations in particular cells. Among monocots, controlled biosilicification occurs in several different forms and is restricted to commelinids and orchids. Methods We utilized energy‐

Efficient Red Light–Driven Singlet Oxygen Photocatalysis with an Osmium‐Based Coulombic Dyad

Angewandte Chemie, EarlyView.
Red light‐absorbing bichromophores with straightforward preparation and superior photocatalytic activity were developed. Spectroscopic studies provided deep insights into the intra‐ion‐pair energy transfer key step and the novel approach. Abstract Photoactive osmium complexes are widely used sensitizers for the generation of singlet oxygen because they

Association Between Moraxella catarrhalis and Nodular Lymphocyte‐Predominant Hodgkin Lymphoma

American Journal of Hematology, EarlyView.
ABSTRACT Nodular lymphocyte‐predominant Hodgkin Lymphoma (NLPHL) may be an antigen‐driven malignancy. Recent studies demonstrated that in NLPHL patients, lymphoma B‐cell receptor can bind proteins derived from Moraxella catarrhalis (MC) and Rothia mucilaginosa (RM). We examined whether MC and RM can be detected in NLPHL lymph nodes.

Harnessing Bifunctional N‐Benzoyloxyamides for Photoredox Amidative Dual Functionalizations of Alkenes

Angewandte Chemie, EarlyView.
A novel photocatalytic strategy is presented for intermolecular amidative dual functionalization of alkenes using N‐benzoyloxyamides as bifunctional N─O reagents. The method enables efficient olefin 1,2‐amidooxygenation and significantly extends its reactivity to encompass amidoazidation, diamination, and formal anti‐Markovnikov hydroamidation.

A Population‐Based Study of Limb Body Wall Complex With Proposed Features for Prenatal Diagnosis

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Limb body wall complex (LBWC) is a lethal condition comprising major congenital anomalies. Although currently diagnosed in the early prenatal period, historical diagnostic criteria are based on detailed pathological assessments. Prenatal and postnatal findings of LBWC and their phenotypic overlap with body stalk anomaly (BSA) and recurrent ...

Research Note: A deep learning method segments chicken keel bones from whole-body X-ray images

Poultry Science
: Most commercial laying hens suffer from sternum (keel) bone damage including deviations and fractures. X-raying hens, followed by segmenting and assessing the keel bone, is a key to automating the monitoring of keel bone condition.

Management of Cardiovascular Health Issues in Turner Syndrome: Expert Insights and Expanded Recommendations From the 2024 Guideline Development Team

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Turner syndrome (TS) is frequently complicated by congenital heart disease (CHD). While left‐sided lesions such as bicuspid aortic valve (BAV) and coarctation of the aorta are the most common structural heart lesions in TS, other anomalies, such as aortic arch malformations, hypoplastic left heart syndrome (HLHS), persistent left superior vena

Deconstructive Radical–Radical Coupling for Programmable Remote Acylation

Angewandte Chemie, EarlyView.
A unified approach to access a variety of 1,n‐dicarbonyls through a radical‐promoted deconstructive process utilizing dual photocatalysis/carbene catalysis is reported. The utility of this strategy is demonstrated with a broad scope with robust functional group tolerance along with application in the preparation of γ‐amino esters, three‐component ...
