Comparative Analysis of Electrocautery Versus LigaSure Energy-based Device for Anterolateral Thigh Free Flap Dissection

open access: yesPlastic and Reconstructive Surgery, Global Open
Background:. The anterolateral thigh (ALT) free flap is widely used in reconstructive surgery, but intramuscular perforator dissection remains technically demanding and time-consuming.

The plastic limit of clays [PDF]

open access: yes, 2013
The plastic limit of soils was first described by Atterberg in 1911. The thread-rolling test was standardised at the US Public Roads Bureau in the 1920s and 1930s, and has subsequently become one of the standard tests of soil mechanics.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Retention of Broken Cannula Tip Following Liposuction-assisted Debulking of Lower Limb Flap: Rare Case Report

open access: yesPlastic and Reconstructive Surgery, Global Open
Summary:. Liposuction has become a highly common procedure performed by plastic surgeons since its advent in 1979. However, it is not without risk. The authors report their experience with breakage and retention of the tip of a liposuction infiltration ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Comparing phthalate exposure between bottlenose dolphins (Tursiops truncatus) residing in urban and rural environments

open access: yesFrontiers in Marine Science
IntroductionExposure to phthalate esters has previously been documented in bottlenose dolphins (Tursiops truncatus) inhabiting an urban estuary (Sarasota Bay, FL, USA; 2010-2019).

Processing of Plastics [PDF]

open access: yesEnvironmental Health Perspectives, 1975
An overview is given of the processing of plastic materials from the handling of polymers in the pellet and powder form to manufacturing of a plastic fabricated product. Various types of equipment used and melt processing ranges of various polymer formulations to make the myriad of plastic products that are commercially available are discussed.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
