Reversible light-responsive protein hydrogel for on-demand cell encapsulation and release.

The design of biomaterials that can reconfigure on-demand in response to external stimuli is an emerging area in materials research. However, achieving reversible assembly of protein-based biomaterials by light input remains a major challenge. Here, we present the engineering of a new protein material that is capable of switching between liquid and solid state reversibly, controlled by lights of different wavelengths.

Integrating CNN and Bi-LSTM for protein succinylation sites prediction based on Natural Language Processing technique.

Protein succinylation, a post-translational modification wherein a succinyl group (-CO-CH₂-CH₂-CO-) attaches to lysine residues, plays a critical regulatory role in cellular processes. Dysregulated succinylation has been implicated in the onset and progression of various diseases, including liver, cardiac, pulmonary, and neurological disorders. However, identifying succinylation sites through experimental methods is often labor-intensive, costly, and technically challenging.

In Situ Raman Spectroscopy for Early Corrosion Detection in Coated AA2024-T3.

Here we describe the synthesis and evaluation of a molecular corrosion sensor that can be applied in situ in aerospace coatings, then used to detect corrosion after the coating has been applied. A pH-sensitive molecule, 4-mercaptopyridin (4-MP), is attached to a gold nanoparticle to allow surface-enhanced Raman-scattering (SERS) for signal amplification. These SERS nanoparticles, when combined with an appropriate micron-sized carrier system, are incorporated directly into an MIL-SPEC coating and used to monitor the process onset and progression of corrosion using pH changes occurring at the metal-coating interface.

Vaginal Antiseptic Preparation at the Time of Hysterectomy: A Systematic Review and Meta-Analysis.

Objective: To compare the rates of surgical site infection (SSI) after hysterectomy using vaginal antisepsis with chlorhexidine gluconate (CHG) versus povidone-iodine (PI).

Data Sources: PubMed, Embase, and Clinicaltrials.gov databases were queried from January 1, 1985 through Dec 7, 2023.

Effect of a Narrative-Based Online Course Aimed at Reducing Stigma Toward Transgender Children and Adolescents: Longitudinal Observational Study.

Background: Stigma toward transgender children and adolescents negatively impacts their health and educational outcomes. Contact with members of stigmatized groups can dismantle stereotypes and reduce stigma by facilitating exposure to the unique cognitive and emotional perspectives of individuals within the group. Recent evidence suggests that video-based contact interventions can be as effective as face-to-face encounters, but challenges lie in protecting the identities of transgender youth, since many of them live in stealth.
