Bistable Functions and Signaling Motifs in Systems Chemistry: Taking the Next Step Toward Synthetic Cells.

ConspectusA key challenge in modern chemistry research is to mimic life-like functions using simple molecular networks and the integration of such networks into the first functional artificial cell. Central to this endeavor is the development of signaling elements that can regulate the cell function in time and space by producing entities of code with specific information to induce downstream activity. Such artificial signaling motifs can emerge in nonequilibrium systems, exhibiting complex dynamic behavior like bistability, multistability, oscillations, and chaos.

Proper 5'-3' cotranslational mRNA decay in yeast requires import of Xrn1 to the nucleus.

The budding yeast Xrn1 protein shuttles between the nucleus, where it stimulates transcription, and the cytoplasm, where it executes the major cytoplasmic mRNA decay. In the cytoplasm, apart from catalyzing 5'→3' decay onto non translated mRNAs, Xrn1 can follow the last translating ribosome to degrade the decapped mRNA template, a process known as "cotranslational mRNA decay". We have previously observed that the import of Xrn1 to the nucleus is required for efficient cytoplasmic mRNA decay.

Disparities of women's authorship in Colombia: A cross-sectional analysis.

Using interpretative phenomenological analysis, we conducted in-depth interviews with nine Israeli adults who lost a parent in childhood. The study drew on the dual process model of coping with loss to examine how early loss of a parent is expressed through adult relationships.

DoxyPEP Implementation Preferences for Bacterial STD Prevention Among Gay, Bisexual, and Other Men Who Have Sex with Men Living With and Without HIV in Los Angeles: A Mixed-Methods Approach.

Bacterial sexually transmitted diseases (STDs) remain prominent in the United States among gay, bisexual, and other men who have sex with men (GBMSM). Doxycycline for post-exposure prophylaxis (DoxyPEP) is a regimen by which the antibiotic doxycycline is taken after sex to prevent bacterial STDs, such as, chlamydia, gonorrhea, and syphilis. Despite this, this study was conducted because there are a limited number of publications that describe GBMSM's knowledge of, and interest in, taking DoxyPEP and preferences regarding its implementation.

A Multipotent PROX1+ Tumor Stem/Progenitor Cell Population Emerges During Intestinal Tumorigenesis and Mediates Radioresistance in Colorectal Cancer.

Colorectal carcinoma (CRC) progression is associated with an increase in PROX1+ tumor cells, which exhibit features of CRC stem cells and contribute to metastasis. Here, we aimed to provide a better understanding to the function of PROX1+ cells in CRC, investigating their progeny and their role in therapy resistance. PROX1+ cells in intestinal adenomas of ApcMin/+ mice expressed intestinal epithelial and CRC stem cell markers, and cells with high PROX1 expression could both self-renew tumor stem/progenitor cells and contribute to differentiated tumor cells.

Chiral Bis-8-Aryl-isoquinoline Bis-alkylamine Iron Catalysts for Asymmetric Oxidation Reactions.

A novel class of bis-8-aryl-isoquinoline () bis-alkylamine iron complexes, Fe()(OTf) and Fe()(OTf) ( = dipyrrolidinyl or = ,'-dimethylcyclohexyl-diamine), for asymmetric oxidation reactions is reported. The scalable divergent synthesis of 8-aryl-3-formylisoquinolines (), the key intermediates in preparing these ligands, enables precise structural and electronic tuning around the metal center. The enantioselective epoxidation and hydroxy carbonylation of conjugated alkenes, mediated by the Fe() catalyst with HO as the oxidant, demonstrates the potential of these redox Fe[N] catalysts in inducing face selection in oxygen transfer transformations.

Moreover, the intrinsic difficulty of ordering the bio-organic self-assemblies into stable large-scale arrays in the liquid environment for engineering devices severely restricts their extensive applications.

Hypotensive Episodes Identified on 24-Hour Ambulatory Blood Pressure and Impaired Cognitive Function: Insights From the SPRINT Study.

Background: Hypotensive episodes detected by 24-hour ambulatory blood pressure (BP) monitoring capture daily cumulative hypotensive stress and could be clinically relevant to cognitive impairment, but this relationship remains unclear.

Methods: We included participants from the Systolic Blood Pressure Intervention Trial (receiving intensive or standard BP treatment) who had 24-hour ambulatory BP monitoring measured near the 27-month visit and subsequent biannual cognitive assessments. We evaluated the associations of hypotensive episodes (defined as systolic BP drops of ≥20 mm Hg between 2 consecutive measurements that reached <100 mm Hg) and hypotensive duration (cumulative time of systolic BP <100 mm Hg) with subsequent cognitive function using adjusted linear mixed models.
