Valence-engineering modulation of MoS clusters for enhancing biocatalytic activity.

Earth-abundant MoS with the advantages of a stable structure, tunable bandgap, and easy shear has great potential for applications in the fields of catalysis, biomedicine, and so on. However, the biocatalytic activity of MoS remains little investigated and is insufficient for biomedical applications. In this work, we develop ultra-small and water-soluble MoS clusters with superior antioxidant activity and enzyme-like activity valence-engineering modulation with Ce doping.

Unveiling the Photoluminescence Mechanism of Carbonized Polymer Dots: Evolution and Synergistic Photoluminescence of Multiple Molecular Fluorophores.

Carbonized polymer dots (CPDs) are a class of exceptional fluorescent materials with diverse applications. However, their photoluminescence (PL) mechanism remained enigmatic and controversial, hindering further development and application. While molecular fluorophores explain primary fluorescence in some CPDs, the overall PL of CPDs still cannot be fully explained, such as their excitation-dependent behaviors, let alone the modulation of PL.

Intensity correlations in the Wigner representation.

We derive a compact expression for the second-order correlation function [Formula: see text] of a quantum state in terms of its Wigner function, thereby establishing a direct link between [Formula: see text] and the state's shape in phase space. We conduct an experiment that simultaneously measures [Formula: see text] through direct photocounting and reconstructs the Wigner function via homodyne tomography. The results confirm our theoretical predictions.

Reversible and irreversible retention of heavy metals in saturated porous media: association with kaolin.

Contamination of heavy metals (HMs) has caused increasing concern due to their ecological toxicities and difficulties in degradation. The transport, retention, and release of HMs in porous media are highly related to their environmental fate and risk to groundwater. Column transport experiments and numerical simulations were conducted to investigate the retention and release behaviors of Cu, Pb, Cd, and Zn in the presence and absence of kaolin under varying ionic strengths and cation types.

Different studies showed that the association between muscular atrophy and mortality in patients with chronic obstructive pulmonary disease (COPD) was unclear.

The design and development of LRRK2 inhibitors as novel therapeutics for Parkinson's disease.

Parkinson's disease (PD) is a common neurodegenerative disease affecting nearly 10 million people worldwide and placing a heavy medical burden on both society and families. However, due to the complexity of its pathological mechanisms, current treatments for PD can only alleviate patients' symptoms. Therefore, novel therapeutic strategies are urgently sought in clinical practice.

Methods: One hundred patients with NSCLC who underwent surgery, systematic lymph node dissection, who had undergone 18FFDG PET/CT for initial staging were divided into two groups: lymph node metastasis and non-metastasis.

Prospects for potential therapy targeting immune‑associated factors in endometriosis (Review).

Endometriosis (EM) is a chronic inflammatory disease that is one of the most common causes of gynecological systemic lesions in women before menopause. The most representative histological feature of EM is that the endometrium appears outside of the uterine cavity, often in the ovary. Although it is generally accepted that the epithelial and stromal cells of the ectopic endometrium are not malignant, they still have numerous similarities to malignant tumors, including considerable changes to the immune microenvironment (immune monitoring disorder), the creation of a specific hormone environment, high levels of oxidative stress, chronic inflammation and abnormal immune cell regulation.

NIR-II upconversion nanomaterials for biomedical applications.

As a nonlinear optical phenomenon, upconversion (UC) occurs when two or more low-energy excitation photons are sequentially absorbed and emitted. Upconversion nanomaterials exhibit superior photostability, non-invasiveness, a unique near-infrared anti-Stokes shift, and enhanced tissue penetration capability. However, general upconversion nanomaterials typically utilize visible light (400-700 nm) for excitation, leading to limited tissue penetration, background signal interference, limited excitation efficiency and imaging quality issues due to tissue absorption and scattering.

Insights into renal damage in hyperuricemia: Focus on renal protection (Review).

The incidence of hyperuricemia has increased recently, posing a serious threat to public health. Hyperuricemia is associated with an increased risk of gout, chronic kidney disease (CKD), obesity, metabolic syndrome, type 2 diabetes mellitus, hypertension, hypertriglyceridaemia, metabolic dysfunction‑associated steatotic liver disease, acute kidney injury, coronary heart disease and cardiovascular disease (CVD). These diseases are commonly accompanied by varying degrees of kidney damage.

[Retracted] NG25, an inhibitor of transforming growth factor‑β‑activated kinase 1, ameliorates neuronal apoptosis in neonatal hypoxic‑ischemic rats.

Following the publication of this paper, it was drawn to the Editors' attention by a concerned reader that certain of the TUNEL assay data shown in Fig. 4B were strikingly similar to data appearing in different form in another article written by different authors at different research institutes that had already been submitted for publication to the journal (which has subsequently been retracted). Owing to the fact that these contentious data had already apparently been submitted for publication prior to the receipt of this paper to , the Editor has decided that this paper should be retracted from the Journal.

Recent advances in nanomaterials for the detection of mycobacterium tuberculosis (Review).

The world's leading infectious disease killer tuberculosis (TB) has >10 million new cases and ~1.5 million mortalities yearly. Effective TB control and management depends on accurate and timely diagnosis to improve treatment, curb transmission and reduce the burden on the medical system.

Thermodynamics and models for small nanoparticles upon protein adsorption.

Proteins are some of the most important components in living organisms. When nanoparticles enter a living system, they swiftly interact with proteins to produce the so-called "protein corona", which depicts the adsorption of proteins on large nanoparticles (normally tens to hundreds of nanometers). However, the sizes of small nanoparticles (typically, fluorescent nanomaterials such as quantum dots, noble metal nanoclusters, carbon dots, ) are less than 10 nm, which are comparable or even much smaller than those of proteins.

Quercetin attenuates the symptoms of osteoarthritis and by suppressing ferroptosis via activation of AMPK/Nrf2/Gpx4 signaling.

Osteoarthritis (OA) is a common joint disorder involving the cartilage and other joint tissues. Quercetin (QCT) serves a protective role in the development of OA. However, to the best of our knowledge, the regulatory mechanisms of QCT in the progression of OA have not yet been fully elucidated.

Research progress on the molecular mechanisms of Saikosaponin D in various diseases (Review).

Bupleurum, a Traditional Chinese Medicine (TCM) herb, is widely used in China and other Asian countries to manage chronic liver inflammation and viral hepatitis. Saikosaponin D (SSD), a triterpenoid saponin extracted from Bupleurum, exhibits extensive pharmacological properties, including anti‑inflammatory, antioxidant, anti‑apoptotic, anti‑fibrotic and anti‑cancer effects, making it a therapeutic candidate for numerous diseases. Clarifying the targets and molecular mechanisms underlying TCM compounds is essential for scientifically validating TCM's therapeutic roles in disease prevention and treatment, as well as for identifying novel therapeutic targets and lead compounds.
