Cellular communication network factor 1 (CCN1), also known as cysteine-rich angiogenic inducer 61 (CYR61), is a pivotal member of the CCN family, which comprises six secretory matricellular proteins. CCN1 exhibits multifaceted biological functions, including regulation of cell proliferation, differentiation, senescence, angiogenesis and tissue repair. Current evidence demonstrates that CCN1 activates intracellular signalling cascades by binding to receptors such as integrins and heparan sulphate proteoglycans (HSPGs), thereby mediating its biological effects.

Rab GTPases are key regulators of vesicular trafficking, not only switching between active and inactive forms but also cycling between donor/resident and target membranes, a process regulated by factors including guanine nucleotide dissociation inhibitors (RabGDIs), whose function is largely unknown in plants. By reverse genetic approaches, we demonstrate that Arabidopsis RabGDIs redundantly mediate male fertility such that the functional loss of RabGDIs compromises pollen development, germination, and directional growth of pollen tubes. By combining cellular and pharmacological approaches, we demonstrate that RabGDIs are critical for the targeting of Rab GTPases not only in secretory but also in vacuolar pathways.

Ethnopharmacological Relevance: Primary dysmenorrhea (PD) is a prevalent condition affecting women globally. Corydalis rhizoma (known as Yanhusuo in Chinese, YHS) is commonly used to treat PD. However, the mechanisms by which raw-YHS (YHS-R) and vinegar-processed YHS (YHS-V) exert the therapeutic effects on PD remain unclear.

The 23-valent pneumococcal polysaccharide vaccine (PPV23) is recommended for adults to prevent pneumococcal diseases, while its effectiveness over time remains unclear. This study aimed to assess the age- and time-dependent effectiveness of PPV23 in reducing community-acquired pneumonia (CAP) incidence among adults aged 60 and older in China. We conducted a prospective cohort study in Shanghai, China, identifying CAP cases via inpatient and outpatient medical records.

Both probiotics and prebiotics can regulate gut microbiota and produce metabolites that are beneficial to the host, showing potential therapeutic prospects for ulcerative colitis (UC). This study aimed to investigate the therapeutic effects and mechanisms of low-, medium-, and high-dose probiotic mixtures ( subsp. XLTG11: Glory LP16: CCFM8661) combined with oligofructose (FOS) on DSS-induced colitis mice.

Introduction: Myasthenia gravis (MG), an IgG-mediated autoimmune disorder targeting neuromuscular junctions, shows refractory in 12-20% of generalised MG (gMG) patients despite immunotherapies. Plasma exchange (PLEX) transiently depletes pathogenic mediators, while neonatal Fc receptor antagonists (eg, efgartigimod) offer novel therapeutic potential. Both PLEX and efgartigimod require adjunctive non-steroidal immunosuppressive therapy (NSIST) for sustained remission.

Surface-enhanced Raman scattering (SERS), despite its high sensitivity in molecular fingerprint detection, typically lacks chiral specificity. Chiral metal nanoclusters (CMNCs) with sub-3 nm cores hold promise for chiral molecular sensing, yet their application in SERS-based chiral recognition remains largely unexplored. In this study, two-dimensional self-assembly of Au nanoparticles (NPs, 30 ∼ 50 nm) functionalized with D- or L-penicillamine (Pen) stabilized sub-3 nm Au nanoclusters (NCs) were constructed as SERS-active substrates.

Glioblastoma (GBM), one of the most aggressive malignant tumors of the central nervous system, exhibits high recurrence rates and multiple pathological mechanisms, leading to an extremely poor prognosis for patients. Photodynamic therapy (PDT) has emerged as a significant research focus in solid tumor therapy due to its high efficacy and safety, inducing tumor cell-specific damage through a series of reactions mediated by photosensitizers. However, the blood-brain barrier (BBB) impedes drug delivery, and enhancing the penetration of photosensitizers across the BBB and targeting the lesion has become a critical challenge in the application of PDT for GBM.

Real-time visualization of immune effector functions remains pivotal for advancing cancer immunotherapy. However, most existing molecular probes are hindered by limited sensitivity and specificity due to their "always on" signals and the absence of targeted characteristics. To address this limitation, we engineered an activatable nanoprobe (A-GNP) through the integration of granzyme B-cleavable peptide substrates with CD63-targeting aptamers on gold nanoparticles.

Introduction: Constipation is a common gastrointestinal disease, the incidence of which has been increasing year by year in recent years, and prolonged constipation seriously affects the physical and mental health of patients. Constipation often leads to dysbiosis of the intestinal flora, which in turn exacerbates intestinal dysfunction, and this may be an important mechanism for the development of constipation. Studies have shown that probiotics may be effective in relieving constipation by regulating intestinal flora.

Intrathoracic airway segmentation in computed tomography is important for quantitative and qualitative analysis of various chronic respiratory diseases and bronchial surgery navigation. However, the airway tree's morphological complexity, incomplete labels resulting from annotation difficulty, and intra-class imbalance between main and terminal airways limit the segmentation performance.Three methodological improvements are proposed to deal with the challenges.

Non-thermal processing encompasses a range of emerging food technologies, including high-pressure processing (HPP), pulsed electric field (PEF), cold atmospheric plasma (CAP), high-pressure carbon dioxide (HPCD), and ultrasound (US). Unlike traditional thermal processing or chemical preservatives, these methods offer advantages such as lower energy consumption, enhanced environmental sustainability, and effective microbial inactivation, thereby extending food shelf life. Moreover, they can better preserve the nutritional integrity, color, flavor, and texture of food products.

Recent advancements in deep learning techniques have contributed to developing improved polyp segmentation methods, thereby aiding in the diagnosis of colorectal cancer and facilitating automated surgery like endoscopic submucosal dissection (ESD). However, the scarcity of well-annotated data poses challenges by increasing the annotation burden and diminishing the performance of fully-supervised learning approaches. Additionally, distribution shifts due to variations among patients and medical centers require the model to generalize well during testing.
