Single stage direct -to- implant breast reconstruction following mastectomy (The use of Ultrapro® Mesh).

Background: Immediate breast reconstruction (IBR) with direct to implant (DTI) is the preferred method of reconstruction by many surgeons and patients, however, acellular dermal matrix (ADM) and other synthetic meshes are expensive especially in low- and middle-income countries. AIM OF THE WORK: To evaluate the technique, indications, aesthetic outcomes, and short and long-term complications of DTI breast reconstruction performed with Ultrapro®, a low-cost alternative mesh to ADM and other synthetic meshes.

Methods: Our study is a prospective cohort study that was conducted on 133 patients who experienced IBR following nipple-sparing mastectomy (NSM) or skin sparing mastectomy (SSM) using silicone implants and Ultrapro® mesh between December 2020 and December 2023.

Modelling human postural stability and muscle activation augmented by a supernumerary robotic tail.

Wearable robots have promising characteristics for human augmentation; however, the the design and specification stage needs to consider biomechanical impact. In this work, musculoskeletal software is used to assess the biomechanical implications of having a two-degrees-of-freedom supernumerary robotic tail mounted posterior to the human trunk. Forward and backward tilting motions were assessed to determine the optimal design specification.

GPT-4 performance on querying scientific publications: reproducibility, accuracy, and impact of an instruction sheet.

Background: Large language models (LLMs) that can efficiently screen and identify studies meeting specific criteria would streamline literature reviews. Additionally, those capable of extracting data from publications would enhance knowledge discovery by reducing the burden on human reviewers.

Methods: We created an automated pipeline utilizing OpenAI GPT-4 32 K API version "2023-05-15" to evaluate the accuracy of the LLM GPT-4 responses to queries about published papers on HIV drug resistance (HIVDR) with and without an instruction sheet.

Effect of Technological Factors on the Extraction of Polymeric Condensed Tannins from Acacia Species.

The aim of this research work was to investigate the influence of parameters such as particle size, mass/solvent ratio, temperature and spray drying on the tannin extraction process in order to develop cost-effective methods with better environmental and structural performance. The pods of ssp. (ANT) were fractionated into three fractions, coarse fraction (C) (>2 mm), medium fraction (M) (1-2 mm), and fine fraction (F) < 1 mµ), and extracted with different water-to-pod ratios (2:1, 4:1 and 6:1) at different temperatures (30, 50 and 70 °C).
