A case for broadening our view of mechanism in developmental biology.

Development

January 2025

Department of Organismic and Evolutionary Biology, Museum of Comparative Zoology, Harvard University, Cambridge, MA 02138, USA.

Developmental biologists can perform studies that describe a phenomenon (descriptive work) and/or explain how the phenomenon works (mechanistic work). There is a prevalent perception that molecular/genetic explanations achieved via perturbations of gene function are the primary means of advancing mechanistic knowledge. We believe this to be a limited perspective, one that does not effectively represent the breadth of work in our field.

Generalized Hartree-Fock (GHF) is a long-established electronic structure method that can lower the energy (compared to spin-restricted variants) by breaking physical wave function symmetries, namely and . After an exposition of GHF theory, we assess the use of GHF trial wave functions in phaseless auxiliary field quantum Monte Carlo (ph-AFQMC-G) calculations of strongly correlated molecular systems including symmetrically stretched hydrogen rings, carbon dioxide, and dioxygen. Imaginary time propagation is able to restore symmetry and yields energies of comparable or better accuracy than CCSD(T) with unrestricted HF and GHF references, and consistently smooth dissociation curves─a remarkable result given the relative scalability of ph-AFQMC-G to larger system sizes.

Background: Few population-based studies have assessed sex differences in stroke recurrence. In addition, contributors to sex differences in recurrence and poststroke mortality, including social factors, are unclear. We investigated sex differences in these outcomes and the contribution of social, clinical, and behavioral factors to the sex differences.

Department of Cardiology, The University of Texas MD Anderson Cancer Center, Houston. (B.C.-C., N.A.V.G., N.L.P., L.P.E., V.S.K.S., A.M.O., J.L., G.M., O.H., A.D., S.W.Y., C.A.I., K.C.O.M., S. Kotla, J.-i.A.).

Modulating immune function is a critical strategy in cancer and atherosclerosis treatments. For cancer, boosting or maintaining the immune system is crucial to prevent tumor growth. However, in vascular disease, mitigating immune responses can decrease inflammation and slow atherosclerosis progression.

Downscaling of Non-Van der Waals Semimetallic WN with Resistivity Preservation.

ACS Nano

January 2025

Department of Chemistry, Boston University, 590 Commonwealth Ave., Boston, Massachusetts 02215, United States.

The bulk phase of transition metal nitrides (TMNs) has long been a subject of extensive investigation due to their utility as coating materials, electrocatalysts, and diffusion barriers, attributed to their high conductivity and refractory properties. Downscaling TMNs into two-dimensional (2D) forms would provide valuable members to the existing 2D materials repertoire, with potential enhancements across various applications. Moreover, calculations have anticipated the emergence of uncommon physical phenomena in TMNs at the 2D limit.

Background: Robotic assistance has become increasingly prevalent in spinal surgery in recent years, emerging as a tool to increase accuracy and precision and lower complication rates and radiation exposure. The 7 and 8 Annual Seattle Science Foundation (SSF) Robotics Courses showcased presentations and demonstrations from some of the field's most experiences leaders on latest topics in robotics and spinal surgery, including cutting-edge preoperative planning technologies, augmented reality (AR) in the operating room, cervical fusion with transpedicular screws, and neuro-oncologic management. We provide a scoping review of the use of robotics technology in spinal surgery featuring highlights from the 7 and 8 Annual SSF Robotics Courses.

Background: Early clinical outcomes data for adjunctive systemic sirolimus therapy (SST) for moderate to severe pediatric pulmonary vein stenosis (PVS) are promising but limited.

Objectives: The authors aimed to characterize a cohort of patients treated with SST to determine if SST was associated with a reduction in frequency of PVS interventions.

Methods: Medical records of 45 patients with PVS treated with SST for ≥1 month from 2015 to 2022 were retrospectively reviewed.

The burden of cardiovascular disease has declined in high-income countries in the past 3 decades but is growing in low- and middle-income countries due to epidemiological, demographic, and socioeconomic shifts. A range of cost-effective policies and interventions are available for advancing cardiovascular health (CVH) through primordial, primary, and secondary prevention. We showcase multifaceted challenges that stifle the global progress of CVH including shortcomings in financial protection, health systems, primary health care, national health policies, service coverage, and surveillance.

Background: Recent data showed an association between malnutrition and increased all-cause mortality and thromboembolic risk in patients with atrial fibrillation (AF). However, the impact of malnutrition on the clinical outcomes for patients undergoing catheter ablation for AF is still debated. Our study aimed to examine this relationship using all existing available data.

Introduction: This was the first phase 1 study conducted in the United States. It consisted of dose-escalation (part A) and multiple indication-specific cohort expansion (part B), investigating the safety and preliminary efficacy of toripalimab (anti-programmed cell death-1 inhibitor) in patients with advanced malignancies.

Methods: Patients with advanced malignancies that progressed after treatment with at least one prior line of standard systemic therapy, including the patients with advanced/recurrent cholangiocarcinoma (CCA), received toripalimab 240 mg every 3 weeks in part B.

Introduction: Uveal melanoma remains a disease with aggressive behavior and poor prognosis despite advances in clinical management. Because monotherapy with immune checkpoint inhibitors has led to limited improvement in response rates, combination with other agents that act on the biological basis of oncogenesis has been proposed as a possible therapeutic strategy.

Methods: We designed a phase 1b trial to test the safety and tolerability of selinexor in combination with immune checkpoint inhibitors in patients with advanced uveal melanoma.

Plast Reconstr Surg Glob Open

January 2025

From the Division of Plastic Surgery, Michael E. DeBakey Department of Surgery, Baylor College of Medicine, Houston, TX.

Successful rhinoplasty relies on a deep understanding of nasal anatomy and precise nasal tip control for lasting functional and aesthetic outcomes. Structural grafts, like septal extension grafts, are instrumental in maintaining tip position and projection with minimal long-term changes. This article details a systematic technique to harvest septal cartilage that maximizes graft material and allows for effective septal deviation correction.

Molecular Targets and Small Molecules Modulating Acetyl Coenzyme A in Physiology and Diseases.

ACS Pharmacol Transl Sci

January 2025

Department of Pharmaceutical Sciences, School of Pharmacy, Texas Tech University Health Science Center, Amarillo, Texas 79106, United States.

Acetyl coenzyme A (acetyl-CoA), a pivotal regulatory metabolite, is a product of numerous catabolic reactions and a substrate for various anabolic responses. Its role extends to crucial physiological processes, such as glucose homeostasis and free fatty acid utilization. Moreover, acetyl-CoA plays a significant part in reshaping the metabolic microenvironment and influencing the progression of several diseases and conditions, including cancer, insulin resistance, diabetes, heart failure, fear, and neuropathic pain.
