Spinal accessory nerve transfer for shoulder abduction has no benefit over supraclavicular exploration and nerve grafting in brachial plexus birth injury: a systematic review.

Introduction: Brachial plexus birth injury (BPBI) has an incidence of 0.9 per 1,000 live births in the population. Techniques for repair classically include supraclavicular exploration and nerve grafting (SENG) and more recently nerve transfer, namely of the spinal accessory nerve (SAN) to the suprascapular nerve (SSN) to improve functional outcomes such as glenohumeral abduction and external rotation.

Modulating the Potency of BRD4 PROTACs at the Systems Level with Amine-Acid Coupling Reactions.

Protein degradation using proteolysis targeting chimeras (PROTACs) represents a promising therapeutic strategy. PROTACs are heterobifunctional molecules that consist of a target-binding moiety and an E3 ligase binding moiety, connected by a linker. These fragments are frequently united via amide bonds.

Estimation of fatty acid composition in mammary adipose tissue using deep neural network with unsupervised training.

Purpose: To develop a deep learning-based method for robust and rapid estimation of the fatty acid composition (FAC) in mammary adipose tissue.

Methods: A physics-based unsupervised deep learning network for estimation of fatty acid composition-network (FAC-Net) is proposed to estimate the number of double bonds and number of methylene-interrupted double bonds from multi-echo bipolar gradient-echo data, which are subsequently converted to saturated, mono-unsaturated, and poly-unsaturated fatty acids. The loss function was based on a 10 fat peak signal model.

Swedish female and male general surgeons differ in personality traits.

Background And Aims: Evidence suggests that female surgeons achieve comparable or even more favorable outcomes than male surgeons. It is currently unclear what factors contribute to these potential differences. Possible explanations might be differences in personality traits, communication style, attitude, and risk-taking behavior.
