Aaron Diamond AIDS Research Center, Columbia University Vagelos College of Physicians and Surgeons, New York, NY 10032, USA; Department of Biochemistry and Molecular Biophysics, Columbia University, New York, NY 10027, USA. Electronic address:

Highly pathogenic avian influenza has spilled into many mammals, most notably cows and poultry, with several dozen human breakthrough infections. Zoonotic crossovers, with hemagglutinins mutated to enhance viral ability to use human α2-6-linked sialic acid receptors versus avian α2-3-linked ones, highlight the pandemic risk. To gain insight into these crossovers, we determined the cryoelectron microscopy (cryo-EM) structure of the hemagglutinin from the zoonotic H5N1 A/Texas/37/2024 strain (clade 2.

Sustainable removal of gaseous Hg using sulfur functionalized biochar: Adsorption experiment and life cycle assessment.

Chemosphere

January 2025

Department of Environmental Engineering, Korea University Sejong Campus, 2511 Sejong-ro, Sejong City, 30019, Republic of Korea. Electronic address:

Maximizing the sorption capacity of gaseous Hg by sulfur-functionalized biochar can lead to increased energy consumption and the production of secondary environmental pollutants such as greenhouse gases. This study evaluates the environmental impact of producing sulfurized biochar through a life cycle assessment (LCA), weighing these impacts against the benefits of enhanced Hg removal efficiencies. The biochar's Hg adsorption capacity, which ranges between 3 and 22 μg-Hg/g-biochar, is influenced by several factors: it increases with higher sulfur loading (0-15 %), higher O levels (0-21 %), and longer pyrolysis times (1-5 h).

Objectives: To develop a more robust understanding of the relationship between increased recreational marijuana access and opioid overdose deaths. Increasing opioid-related deaths in conjunction with the rising popularity of liberalized marijuana laws make additional research examining the interrelation of both a timely and insightful question.

Study Design: We use synthetic control method to assess the impact of opening recreational marijuana dispensaries via recreational marijuana legalization (RML) on opioid death rates in Colorado, Washington, and Oregon.

Objectives: Thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy associated with severe deficiency in ADAMTS13. ADAMTS13 deficiency may be secondary to absent or dysfunctional protein production due to mutations in the ADAMTS13 gene (congenital TTP) or autoantibody-mediated clearance and/or inhibition (immune-mediated TTP). This autoimmunity may, albeit rarely, occur secondary to certain medications (eg, ticlopidine).

Deep learning-based quick MLC sequencing for MRI-guided online adaptive radiotherapy: a feasibility study for pancreatic cancer patients.

Phys Med Biol

January 2025

Department of Radiation Oncology, Division of Medical Physics and Engineering​ , UT Southwestern Medical Center, 2280 Inwood Road, Dallas, Texas, 75390-9096, UNITED STATES.

One bottleneck of MRI-guided Online Adaptive Radiotherapy (MRoART) is the time-consuming daily online replanning process. The current leaf sequencing method takes up to 10 minutes, with potential dosimetric degradation and small segment openings that increase delivery time. This work aims to replace this process with a fast deep learning-based method to provide deliverable MLC sequences almost instantaneously, potentially accelerating and enhancing online adaption.

Chimeric antigen receptor (CAR) T-cell products axicabtagene ciloleucel (axi-cel), tisagenlecleucel (tisa-cel), and lisocabtagene maraleucel (liso-cel) are approved for relapsed/refractory large B-cell lymphoma (R/R LBCL). Emerging evidence indicates that delayed CAR T-cell infusion, including prolonged time from leukapheresis to infusion, known as vein-to-vein time (V2Vt), may adversely impact clinical outcomes. We conducted a systematic literature review (SLR) and meta-analysis to identify differences in V2Vt in patients with R/R LBCL treated with axi-cel, tisa-cel, or liso-cel.

Although nucleoporin 98 (NUP98) fusion oncogenes often drive aggressive pediatric leukemia by altering chromatin structure and expression of HOX genes, underlying mechanisms remain elusive. Here, we report that a Hoxb-associated lncRNA HoxBlinc was aberrantly activated in NUP98-PHF23 fusion-driven leukemias. HoxBlinc chromatin occupancies led to elevated MLL1 recruitment and aberrant homeotic topologically associated domains (TADs) that enhanced chromatin accessibilities and activated homeotic/hematopoietic oncogenes.

Importance: Triple-negative breast cancer is an aggressive subtype with a high incidence in young patients, a high incidence in non-Hispanic Black women, and a high risk of progression to metastatic cancer, a devastating sequela with a 12- to 18-month life expectancy. Until recently, one strategy for treating early-stage triple-negative breast cancer was chemotherapy after surgery. However, it was not known whether the addition of immune therapy to postsurgery chemotherapy would be beneficial.

Do unions facilitate or hamper the effectiveness of high-performance work systems (HPWS)? Despite the long-standing interest among labor and human resource scholars on this matter, relevant studies are limited and dated. This research investigates whether and how the interplay between HPWS and unions affects both organizational performance and employee well-being outcomes. The authors argue while unions may attenuate the HPWS effects on organizational performance due to decreased performance climate, the overall impacts of unions are likely beneficial, as they facilitate cooperative climate that contributes to organizational performance and enhances employee well-being, which positively affects longer term organizational outcomes.

Background: People with type 2 diabetes mellitus (T2DM) commonly report a higher fatigue intensity than the general population. However, effective fatigue management is lacking because little is known about other fatigue characteristics, including timing, distress, and quality, as well as the potential fatigue subtypes experienced in people with T2DM.

Objective: To describe fatigue intensity, timing, distress, and quality, and identify fatigue subtypes in people with T2DM.

Chronic itch in older patients is a common problem, with a significant impact on quality of life. Chronic itch in the older population may be attributable to several causes, such as age-related changes, skin conditions, systemic conditions, medications, and psychological conditions. Given the complexity of itch in this population, comorbidities, and polypharmacy in most geriatric patients, treating chronic itch can be challenging for healthcare providers.
