Dilution-driven gel-sol-gel-sol transitions by the sequential evolution of surfactant micelles.

Here are described the dilution-driven gel-sol-gel-sol transitions in aromatic hydrotrope/zwitterionic surfactant bi-component aqueous mixtures. Long and entangled wormlike micelles (WLMs) of concentrated erucyl dimethyl amidopropyl betaine (EAPB) solutions sequentially transform into hexagonal liquid crystal phase (H), highly concentrated spherical micelles (HCSMs), and finally hexagonal close packed micellar phase (HCP) upon gradual introducing an aromatic hydrotrope, sodium salicylate (NaSal). The HCP then successively converts into HCSMs, WLMs, and spherical micelles (SMs) upon further dilution with water, corresponding to a gel-sol-gel-sol transition.

Natural rhythmic speech activates network reorganization with frontal community enhancing communication efficiency in patients with intrinsic brain tumor.

Brain tumors provide unique insights into brain plasticity due to their slow growth compared to acute cerebrovascular diseases. Despite relying on sophisticated functional networks, patients with brain tumors exhibit minimal deficits in higher language functions and demonstrate positive post-injury plasticity; however, the underlying neural mechanisms remain unclear. We utilized high-density electroencephalography to investigate language network plasticity in brain tumor patients without evident language deficits.

V-ATPase in cancer: mechanistic insights and therapeutic potentials.

Vacuolar-type H+-ATPase (V-ATPase) is a crucial proton pump that plays an essential role in maintaining intracellular pH homeostasis and a variety of physiological processes. This review provides an in-depth exploration of the structural components, functional mechanisms, and regulatory modes of V-ATPase in cancer cells. Comprising two main domains, V and V, V-ATPase drives the proton pump through ATP hydrolysis, sustaining the pH balance within the cell and organelles.

A brain-to-text framework for decoding natural tonal sentences.

Speech brain-computer interfaces (BCIs) directly translate brain activity into speech sound and text. Despite successful applications in non-tonal languages, the distinct syllabic structures and pivotal lexical information conveyed through tonal nuances present challenges in BCI decoding for tonal languages like Mandarin Chinese. Here, we designed a brain-to-text framework to decode Mandarin sentences from invasive neural recordings.

Spatiotemporal Microstate Dynamics of Spike-Free Scalp EEG Offer a Potential Biomarker for Refractory Temporal Lobe Epilepsy.

Refractory temporal lobe epilepsy (TLE) is one of the most frequently observed subtypes of epilepsy and endangers more than 50 million people world-wide. Although electroencephalogram (EEG) had been widely recognized as a classic tool to screen and diagnose epilepsy, for many years it heavily relied on identifying epileptic discharges and epileptogenic zone localization, which however, limits the understanding of refractory epilepsy due to the network nature of this disease. This work hypothesizes that the microstate dynamics based on resting-state scalp EEG can offer an additional network depiction of the disease and provide potential complementary evaluation tool for the TLE even without detectable epileptic discharges on EEG.

Computational Design of Ligands for the Ir-Catalyzed C5-Borylation of Indoles through Tuning Dispersion Interactions.

The indole moiety is ubiquitous in natural products and pharmaceuticals. C-H borylation of the benzenoid moiety of indoles is a challenging task, especially at the C5 position. We have combined computational and experimental studies to introduce multiple noncovalent interactions, especially dispersion, between the substrate and catalytic ligand to realize C5-borylation of indoles with high reactivity and selectivity.

Analysis of abdominal adhesion using the ileostomy model.

Abdominal adhesion occurs commonly in clinical practice, causing unfavorable symptoms and readmission. The ileostomy operation is a common surgical procedure and we utilized this model to evaluate abdominal adhesion. Adhesion grade score was calculated in 35 patients (Cohort 1) and subjected to correlation and receiver operating characteristic analysis.

Cerebral blood flow measured by diffuse correlation spectroscopy in children with autism spectrum disorder.

Diffuse correlation spectroscopy (DCS) was used to measure resting-state cerebral blood flow (CBF) in temporal lobes of children with autism spectrum disorder (ASD) and typically developing (TD) children. Twenty-two children with ASD and 34 age-matched TD children were recruited to participate in the experiment. DCS signals were recorded with 3 long source-detector (SD) channels (SD distance = 22.

DNA-encoded chemical libraries yield non-covalent and non-peptidic SARS-CoV-2 main protease inhibitors.

The development of SARS-CoV-2 main protease (M) inhibitors for the treatment of COVID-19 has mostly benefitted from X-ray structures and preexisting knowledge of inhibitors; however, an efficient method to generate M inhibitors, which circumvents such information would be advantageous. As an alternative approach, we show here that DNA-encoded chemistry technology (DEC-Tec) can be used to discover inhibitors of M. An affinity selection of a 4-billion-membered DNA-encoded chemical library (DECL) using M as bait produces novel non-covalent and non-peptide-based small molecule inhibitors of M with low nanomolar K values.

Ca efflux facilitated by co-transport of inorganic phosphate anion in the H/Ca antiporter YfkE.

Ca is an important signaling messenger. In microorganisms, fungi, and plants, H/Ca antiporters (CAX) are known to play key roles in the homeostasis of intracellular Ca by catalyzing its efflux across the cell membrane. Here, we reveal that the bacterial CAX homolog YfkE transports Ca in two distinct modes: a low-flux H/Ca exchange mode and a high-flux mode in which Ca and phosphate ions are co-transported (1:1) in exchange for H.

Mutagenesis and structural analysis reveal the CTX-M β-lactamase active site is optimized for cephalosporin catalysis and drug resistance.

CTX-M β-lactamases are a widespread source of resistance to β-lactam antibiotics in Gram-negative bacteria. These enzymes readily hydrolyze penicillins and cephalosporins, including oxyimino-cephalosporins such as cefotaxime. To investigate the preference of CTX-M enzymes for cephalosporins, we examined eleven active-site residues in the CTX-M-14 β-lactamase model system by alanine mutagenesis to assess the contribution of the residues to catalysis and specificity for the hydrolysis of the penicillin, ampicillin, and the cephalosporins cephalothin and cefotaxime.
