Microplastics (MPs) have emerged as widespread environmental pollutants in aquatic ecosystems, primarily due to the extensive use of plastic products, their persistent nature, and improper disposal methods. It is essential to develop effective purification methods to treat the hazardous MPs in water. Chitin and chitosan (CS) have gained attention as promising adsorbents for MPs because of their low cost, abundance, biodegradability, and the presence of functional groups such as amino and hydroxyl groups, which facilitate the removal of various toxins from wastewater.

Background: Next-generation sequencing (NGS) is widely used for assessing CDKN2A status in cancers due to its high throughput and efficiency. However, discrepancies between NGS and fluorescence in situ hybridization (FISH)-the gold standard for detecting copy number variations (CNVs)-are occasionally observed. This study aimed to evaluate the accuracy of NGS in detecting CDKN2A deletions by comparing it with FISH.

Achieving underwater adhesion remains challenging due to the disruption of interfacial interactions by hydration layers and the ionic environment. This study shows how high adhesion in a saline environment can be achieved in adhesive peptide systems relying on π-π and cation-π interactions using multivalent ions. Monovalent ions (K) disrupt native peptide-peptide interactions, drastically reducing adhesion strength.

The TOX protein (thymocyte selection-associated high mobility group box) is a critical transcription factor implicated in both T acute lymphoblastic leukemia (T-ALL) and CD8 T cell exhaustion. Gene perturbation studies suggest that inhibiting TOX may have therapeutic implications for both leukemia and T cell exhaustion. However, due to its complex molecular mechanisms and intrinsically disordered structure, TOX has not been effectively targeted by small molecules to date.

Hydroxide exchange membranes (HEMs) have attracted extensive attention in energy-related fields, such as fuel cells and water electrolysis, primarily due to their suitability for alkaline environments. However, the practical application of membranes is hindered significantly by their limited conductivity. In this study, a series of amphoteric metal ion-coordinated chitosan (CTS-AM) membranes with enhanced hydroxide ion conductivity are reported.

Marine biofouling and corrosion have become the main problems affecting the development of the marine industry. Silicone-based coatings have been widely used for antifouling and anticorrosion due to their low surface energy. However, the poor adhesion and low mechanical stability of these materials limit their application in complex marine environments.

Rapid and accurate state of health (SOH) estimation of retired batteries is a crucial pretreatment for reuse and recycling. However, data-driven methods require exhaustive data curation under random SOH and state of charge (SOC) retirement conditions. Here, we show that the generative learning-assisted SOH estimation is promising in alleviating data scarcity and heterogeneity challenges, validated through a pulse injection dataset of 2700 retired lithium-ion battery samples, covering 3 cathode material types, 3 physical formats, 4 capacity designs, and 4 historical usages with 10 SOC levels.

Patients with schizophrenia often experience symptoms such as poor insight and disorganized thought, which limit their ability to seek and receive care consistently. In rural settings, systemic factors, including limited resources and transportation, further contribute to difficulties in health care access. Long-acting injectable antipsychotics (LAIs) can improve medication adherence and reduce hospitalizations from relapse.

Purpose: The neuroregulatory center of intraocular pressure (IOP) is located in the hypothalamus. An efferent neural pathway exists between the hypothalamic nuclei and the autonomic nerve endings in the anterior chamber of the eye. This study was designed to investigate whether the paraventricular hypothalamic nucleus (PVH) regulates IOP as the other nuclei do.

  • The study aimed to analyze HER2 status in invasive breast cancer cases where HER2 levels fall between 4.0 and 6.0, which has been a subject of debate in medical literature.
  • The research involved 40 cases classified into two groups based on their HER2/CEP17 ratio, examining various clinicopathological features, treatment responses, and molecular typing to understand the implications of HER2 status.
  • Findings indicated that many cases classified as HER2 positive (from Group A) might actually be HER2 negative, suggesting these patients may not benefit significantly from anti-HER2 treatments, highlighting the need for re-evaluation of HER2 classification criteria.

  • The study explores an automated method using a deep learning AI model to quantify HER2 FISH signals in breast cancer patients, aiming to assist pathologists with efficiency.
  • The AI model analyzed 918 FISH images and showed an overall classification accuracy of 85.33%, with high consistency (95.90%) in the most common group (Group 5).
  • Inconsistencies in other groups were linked to issues like clustered HER2 signals and section quality; more data could enhance accuracy for these less common categories.

-3,4-dihydroxyphenylalanine is an important molecule in the adhesion of mussels, and as an oxidative precursor of natural melanin, it plays an important role in living system. Here, we investigate the effect of the molecular chirality of 3,4-dihydroxyphenylalanine on the properties of the self-assembled films by tyrosinase-induced oxidative polymerization. The kinetics and morphology of pure enantiomers are completely altered upon their co-assembly, allowing the fabrication of layer-to-layer stacked nanostructures and films with improved structural and thermal stability.

Synergistic interactions between 3,4-dihydroxyphenylalanine (Dopa, Y*), cationic residues, and the aromatic rings have been recently highlighted as influential factors that enhance the underwater adhesion strength of mussel foot proteins and their derivatives. In this study, we report the first ever evidence of a cation-catechol-benzene ternary synergy between Y*, lysine (Lys, K), and phenylalanine (Phe, F) in adhesive peptides. We synthesized three hexapeptides containing a different combination of Y*, K, and F, , (KY*), (KF), and (KY*F), respectively, exploring the relationship between the cohesive performance and molecular architecture of peptides.

This study presents novel adhesive materials that use cation-π interactions to achieve highly specific cohesive interaction under water. The materials are short length peptides based on the FKF motif flanked by different side groups. Using the surface forces apparatus, we show that the composition of the side group allows to finely tune the strength of the cohesive and adhesive energies of the peptide and its specificity, meaning its capacity to bind strongly only to substrates bearing the same peptide.

Accumulated clinical evidence has shown that Posner-Schlossman syndrome (PSS) is most likely the result of recurrent human cytomegalovirus (HCMV) infection in the anterior chamber (AC). Establishing an animal model is necessary to investigate the pathogenesis of PSS. In this study, we constructed a mouse model of (PSS) by injecting murine cytomegalovirus (MCMV) into the AC of BALB/c mice.

Transient receptor ion potential (TRP) channels are a cluster of non-selective cation channels present on cell membranes. They are important mediators of sensory signals to regulate cellular functions and signaling pathways. Alterations and dysfunction of these channels could disrupt physiological processes, thus leading to a broad array of disorders, such as cardiovascular, renal and nervous system diseases.

The αvβ3 integrin, a receptor for many extracellular matrix proteins with RGD-sequence motif, is involved in multiple physiological processes and highly expressed in tumor cells, therefore making it a target for cancer therapy and tumor imaging. Several RGD-containing cyclic octapeptide (named LXW analogs) were screened as αvβ3 antagonists with dramatically different binding affinity, and their structure-activity relationship (SAR) remains elusive. We performed systematic SAR studies and optimized LXW analogs to improve antagonistic potency.

Article Synopsis
  • Abnormal aquaporin (AQP) expression, particularly AQP8, has been linked to the progression of human cancers, including esophageal cancer.
  • The study explored how epidermal growth factor (EGF) affects AQP8 expression and cell migration in esophageal cancer Eca-109 cells, demonstrating that EGF significantly enhances both AQP8 levels and cell movement.
