Dual α-globin-truncated erythropoietin receptor knockin restores hemoglobin production in α-thalassemia-derived erythroid cells.

The most severe form of α-thalassemia results from loss of all four copies of α-globin. Postnatally, patients face challenges similar to β-thalassemia, including severe anemia and erythrotoxicity due to the imbalance of β-globin and α-globin chains. Despite progress in genome editing treatments for β-thalassemia, there is no analogous curative option for α-thalassemia.

Objective: This study aims to evaluate the success rates and complications associated with different free flap donor sites used in surgical reconstruction for mandibular osteoradionecrosis, providing insights to aid clinical decision-making.

Data Sources: MEDLINE, Embase, Cochrane, and Web of Science.

Review Methods: Comprehensive database searches were conducted up to October 2023.

Corn stover variability drives differences in bisabolene production by engineered Rhodotorula toruloides.

Unlabelled: Microbial conversion of lignocellulosic biomass represents an alternative route for production of biofuels and bioproducts. While researchers have mostly focused on engineering strains such as Rhodotorula toruloides for better bisabolene production as a sustainable aviation fuel, less is known about the impact of the feedstock heterogeneity on bisabolene production. Critical material attributes like feedstock composition, nutritional content, and inhibitory compounds can all influence bioconversion.

Four-dimensional computed tomography and ultrasonography for prediction of pathological parathyroid location: a retrospective review of a single surgeon's patients at a single institution.

Background: Pre-operative imaging is a well-established practice for managing hyperparathyroidism with the plan for excision; however, there is a paucity of information regarding the success rate of concordant imaging studies. Our goal was to compare the accuracy (sensitivity) of four-dimensional computed tomography (4DCT) and ultrasound (US) when predicting the side and quadrant of parathyroid lesions, confirmed with surgical location (from a single surgeon).

Methods: A retrospective review of 437 patients from a single surgeon undergoing parathyroidectomy from December 2013 to January 2020 at an academic medical center was performed.

Association between blood transfusion and outcomes of free flap head and neck cancer surgery.

Objective: Investigate the impact of patient risk factors and blood transfusions in Head and Neck free flap surgeries.

Study Design: Retrospective chart review.

Setting: Single tertiary referral center.

First-Principles Nonadiabatic Dynamics of Molecules at Metal Surfaces with Vibrationally Coupled Electron Transfer.

Accurate description of nonadiabatic dynamics of molecules at metal surfaces involving electron transfer has been a long-standing challenge for theory. Here, we tackle this problem by first constructing high-dimensional neural network diabatic potentials including state crossings determined by constrained density functional theory, then applying mixed quantum-classical surface hopping simulations to evolve coupled electron-nuclear motion. Our approach accurately describes the nonadiabatic effects in CO scattering from Au(111) without empirical parameters and yields results agreeing well with experiments under various conditions for this benchmark system.

Functional Status Predicts Delay to Radiation in Free Tissue Transfer for Head and Neck Cancer.

Objective: Evaluate the effect of functional status and patient factors on delays in treatment with adjuvant therapy.

Methods: Retrospective chart review (2020-2022) was conducted at a single tertiary referral center. Data were collected between January 2020 and October 2022, and 63 patients underwent free flap reconstructive surgery of the head and neck due to the presence of cancer and received adjuvant radiation therapy (RT).

A microporous polymer based on nonconjugated hindered biphenyls that emits blue light.

Microporous organic polymers that have three-dimensional connectivity stemming from monomers with tetrahedral or tetrahedron-like geometry can have high surface areas and strong fluorescence. There are however few examples of such polymers based on hindered biaryls, and their fluorescence has not been studied. Hypothesizing that the contortion in a hindered biphenyl moiety would modulate the optical properties of a polymer built from it, we synthesized a meta-enchained polyphenylene from a 2,2',6,6'-tetramethylbiphenyl-based monomer, in which the two phenyl rings are nearly mutually perpendicular.

Functional Outcomes After the Sacrifice of Mandibular Condyle Using Fibula Free Flap for Immediate Surgical Reconstruction.

Introduction Head and neck cancer with mandibular invasion often necessitates composite resection, leading to defects requiring reconstruction. Microvascular fibula free flap (FFF) surgery is a common approach for this purpose. In this study, we focus on our experience with condyle sacrifice, emphasizing treatment outcomes and functional results.

Dual α-globin and truncated EPO receptor knockin restores hemoglobin production in α-thalassemia-derived red blood cells.

Alpha-thalassemia is an autosomal recessive disease with increasing worldwide prevalence. The molecular basis is due to mutation or deletion of one or more duplicated α-globin genes, and disease severity is directly related to the number of allelic copies compromised. The most severe form, α-thalassemia major (αTM), results from loss of all four copies of α-globin and has historically resulted in fatality .

Copper(I) Iodide Thin Films: Deposition Methods and Hole-Transporting Performance.

The pursuit of p-type semiconductors has garnered considerable attention in academia and industry. Among the potential candidates, copper iodide (CuI) stands out as a highly promising -type material due to its conductivity, cost-effectiveness, and low environmental impact. CuI can be employed to create thin films with >80% transparency within the visible range (400-750 nm) and utilizing various low-temperature, scalable deposition techniques.

Reconstruction for Salvage Laryngectomy With Limited Pharyngectomy.

Importance: Closure technique for optimization of postoperative and functional outcomes following salvage laryngectomy remains an area of debate among head and neck surgeons.

Objective: To investigate the association of salvage laryngectomy closure technique with early postoperative and functional outcomes.

Design, Setting, And Participants: This retrospective cohort study included patients from 17 academic, tertiary care centers who underwent total laryngectomy with no or limited pharyngectomy after completing a course of definitive radiotherapy or chemoradiotherapy with curative intent between January 2011 and December 2016.

Achieving the Fundamental Quantum Limit of Linear Waveform Estimation.

Sensing a classical signal using a linear quantum device is a pervasive application of quantum-enhanced measurement. The fundamental precision limits of linear waveform estimation, however, are not fully understood. In certain cases, there is an unexplained gap between the known waveform-estimation quantum Cramér-Rao bound and the optimal sensitivity from quadrature measurement of the outgoing mode from the device.
