The title complex, [Cu(2)Br(3)(C(11)H(9)N(2)O(2))](n), was one of three isolated by slow evaporation of an acetonitrile reaction mixture of CuBr(2) with di-2-pyridyl ketone (1:1 molar ratio). The title complex contains a 2:1 metal-to-ligand ratio of copper(II) with the hydrated form of the ligand, di-2-pyridylmethane-diol. The two copper centers are bridged by a bromide ion and the alk-oxy O atom, and the Cu-Cu distance is 2.9801 (5) Å. The dimeric units are further linked by bromide ions, leading to a two-dimensional extended bridged structure. O-H⋯O hydrogen bonds are present in the crystal structure.

Dependability of Procalcitonin as an Early Predictor of Infection in Open Fractures: An Observational Study.
Cureus
December 2024
Department of Orthopaedics, K S Hegde Medical Academy, Mangaluru, IND.
Introduction Open extremity fractures are complex injuries involving soft tissue disruption and bone discontinuity, often associated with significant morbidity and mortality due to complications such as infection. Infection remains a primary concern, exacerbating patient outcomes and increasing healthcare costs. Procalcitonin (PCT) is a biomarker with potential utility for early detection of infection in these cases.

Quantitative genomic mapping of DNA damage may provide insights into the underlying mechanisms of damage and repair. Sequencing based approaches are bound to the limitations of PCR amplification bias and read length which hamper both the accurate quantitation of damage events and the ability to map them to structurally complex genomic regions. Optical Genome mapping in arrays of parallel nanochannels allows physical extension and genetic profiling of millions of long genomic DNA fragments, and has matured to clinical utility for characterization of complex structural aberrations in cancer genomes.

Eur Radiol

Department of Radiology, Seoul National University College of Medicine, Seoul National University Hospital, Seoul, Republic of Korea.
Objective: This study aimed to develop an open-source multimodal large language model (CXR-LLaVA) for interpreting chest X-ray images (CXRs), leveraging recent advances in large language models (LLMs) to potentially replicate the image interpretation skills of human radiologists.
Materials And Methods: For training, we collected 592,580 publicly available CXRs, of which 374,881 had labels for certain radiographic abnormalities (Dataset 1) and 217,699 provided free-text radiology reports (Dataset 2). After pre-training a vision transformer with Dataset 1, we integrated it with an LLM influenced by the LLaVA network.
ETV2/ER71 regulates hematovascular lineage generation and vascularization through an H3K9 demethylase, KDM4A.

Department of Pediatrics, Emory University School of Medicine, Atlanta, GA, USA.
ETV2/ER71, an ETS (E-twenty six) transcription factor, is critical for hematopoiesis and vascular development. However, research about the molecular mechanisms behind ETV2-mediated gene transcription is limited. Herein, we demonstrate that ETV2 and KDM4A, an H3K9 demethylase, regulate hematopoietic and endothelial genes.

University College London, London, United Kingdom.
Background: The deteriorating mental health of children and young people in the United Kingdom poses a challenge that services and policy makers have found difficult to tackle. Kailo responds to this issue with a community-based participatory and systemically informed strategy, perceiving mental health and well-being as a dynamic state shaped by the interplay of broader health determinants. The initiative works to explore, define and implement locally relevant solutions to challenges shaping the mental health and well-being of young people.
