Platinum micromotors for mucosal penetration and colorectal cancer therapy.

The therapeutic outcomes of medications were restricted by the colonic mucosal barrier during the treatment of colorectal cancer (CRC). Micro/nanomotors can overcome the mucus barriers to reach deep colorectal tumors. In this study, we constructed a novel microsized PLGA-Pt micromotor (MM) driven by hydrogen peroxide (HO) to enhance drug delivery to the CRC tissues and achieve effective antitumor therapy.

Small molecules that targeting p53 Y220C protein: mechanisms, structures, and clinical advances in anti-tumor therapy.

The p53 protein is regarded as the "Guardian of the Genome," but its mutation is tumor progression and present in more than half of malignant tumors. The pro-metastatic property of mutant p53 makes a strong argument for targeting mutant p53 with new therapeutic strategies. However, mutant p53 was considered as a challenging target for drug discovery due to the lack of small molecular binding pockets.

Tailoring pyridine bridged chalcogen-concave molecules for defects passivation enables efficient and stable perovskite solar cells.

Suppressing deep-level defects at the perovskite bulk and surface is indispensable for reducing the non-radiative recombination losses and improving efficiency and stability of perovskite solar cells (PSCs). In this study, two Lewis bases based on chalcogen-thiophene (n-Bu4S) and selenophene (n-Bu4Se) having tetra-pyridine as bridge are developed to passivate defects in perovskite film. The uncoordinated Pb and iodine vacancy defects can interact with chalcogen-concave group and pyridine group through the formation of the Lewis acid-base adduct, particularly both the defects can be surrounded by concave molecules, resulting in effective suppression charge recombination.

Direct reprogramming of human fibroblasts into hair-inducing dermal papilla cell-like cells by a single small molecule.

Dermal papilla cells (DPCs) are a crucial subset of mesenchymal cells in the skin responsible for regulating hair follicle development and growth, making them invaluable for cell-based therapies targeting hair loss. However, obtaining sufficient DPCs with potent hair-inducing abilities remains a persistent challenge. In this study, the Food and Drug Administration (FDA)-approved drug library was utilized to screen small molecules capable of reprogramming readily accessible human skin fibroblasts into functional DPCs.

Baicalin ameliorates neuroinflammation by targeting TLR4/MD2 complex on microglia via PI3K/AKT/NF-κB signaling pathway.

This study aims to elucidate the target and mechanism of baicalin, a clinically utilized drug, in the treatment of neuroinflammatory diseases. Neuroinflammation, characterized by the activation of glial cells and the release of various pro-inflammatory cytokines, plays a critical role in the pathogenesis of various diseases, including spinal cord injury (SCI). The remission of such diseases is significantly dependent on the improvement of inflammatory microenvironment.

Synthesis and biological evaluation of novel pyrrolo[2,3-b]pyridine derivatives as potent GSK-3β inhibitors for treating Alzheimer's disease.

The development of potent glycogen synthase kinase-3β (GSK-3β) inhibitor has been increasingly recognized as the candidate treatment against the multifactorial pathogenic mechanism of Alzheimer's disease (AD). This study prepared various new pyrrolo[2,3-b]pyridine derivatives, evaluated the anti-AD activities and detected the security based on the structure-guided rational design. Our results indicated that many pyrrolo[2,3-b]pyridine derivatives had strong GSK-3β inhibitory activities, particularly compounds 41, 46 and 54, with the half maximal inhibitory concentrations (IC) of 0.

Mixed grafting of small auto- and cryopreserved allo-skin for residual wound repair in severe burn patients: A retrospective study.

Background: The wound repair process for extensively deep burn patients is a recurring and highly challenging endeavor. A prolonged healing time beyond 3 weeks after injury often leads to compromised healing outcomes. The limited availability of autologous skin grafts remains the primary obstacle in achieving timely wound repair.

Effect of marine anoxia on the conversion of macroalgal biomass to refractory dissolved organic carbon.

The input of macroalgal biomass into the deep sea is a crucial process for macroalgal carbon sequestration, but this process may be affected by anoxia. We compared the breakdown of kelp biomass in both normoxic (>4 mg/L O) and anoxic (<2 mg/L O) environments. Following 240 days of decomposition experiment, complete degradation of the kelp biomass occurred in normoxic conditions, whereas under anoxic conditions, relatively 13.

Comparing the Effectiveness of Single Exercises on Improving Exercise Capacity in Chronic Obstructive Pulmonary Disease Patients: Network Meta-Analysis of Randomized Controlled Trials.

Background: Chronic Obstructive Pulmonary Disease (COPD) is a common respiratory disease that significantly impairs the quality of life of patients. Single exercises can help COPD patients focus on enhancing specific physical abilities, and enable a more precise analysis of the specific effects of single exercises on improving exercise capacity in COPD patients.

Objectives: To evaluate the effectiveness of single exercises in improving the exercise capacity of COPD patients and to conduct an indirect comparison to identify the most efficacious intervention.

Neuromuscular Strategies in Dominant and Non-Dominant Legs in Dancers During Dynamic Balance Tasks.

Ballet-based dance training emphasizes the equal development of both legs. However, dancers often perceive differences between their legs during balance or landing. There still needs to be more consensus on the functional difference between dominant (D) and non-dominant legs (ND).

Distinct Transmission of Left- and Right-Handed Magnon Modes in Compensated Ferrimagnet/Antiferromagnet Structures.

The chirality of magnons, exhibiting left- and right-handed polarizations analogous to the counterparts of spin-up and spin-down, has emerged as a promising paradigm for information processing. However, the potential of this paradigm is constrained by the controllable excitation and transmission of chiral magnons. Here, the magnon transmission is explored in the GdFeO/NiO/Pt structures.

Smith-Magenis syndrome with Dandy-Walker malformation in a 2-year-old girl: A case report.

Smith-Magenis syndrome (SMS) and Dandy-Walker malformation (DWM) are uncommon genetic conditions with nonspecific clinical features, which makes reaching a definitive diagnosis challenging. We describe here, a 2-year-old girl who was diagnosed with SMS at the age of 12 months due to delayed growth and development. The child presented to hospital with acute heart failure and respiratory failure.

Preharvest Treatment with Melatonin Improves Antioxidant and Phenylpropanoid Pathways During Postharvest Storage.

is known for its popularity and robust nutritional value. While fresh fruit is a perishable commodity, it has a short post-harvest life and is susceptible to fungal decay after harvest. Melatonin has been reported to delay the aging and quality decline of various fruits and vegetables after harvest.

Innovative Therapeutic Strategies for Myocardial Infarction Across Various Stages: Non-Coding RNA and Stem Cells.

Myocardial infarction (MI) is a highly challenging and fatal disease, with diverse challenges arising at different stages of its progression. As such, non-coding RNAs (ncRNAs), which can broadly regulate cell fate, and stem cells with multi-differentiation potential are emerging as novel therapeutic approaches for treating MI across its various stages. NcRNAs, including microRNAs (miRNAs) and long non-coding RNAs (LncRNAs), can directly participate in regulating intracellular signaling pathways, influence cardiac angiogenesis, and promote the repair of infarcted myocardium.

Interrelation of Natural Polyphenol and Fibrosis in Diabetic Nephropathy.

Diabetic nephropathy (DN) is a common and serious complication of diabetes mellitus and a major cause of end-stage renal disease (ESRD). Renal fibrosis, which corresponds to excessive deposition of extracellular matrix and leads to scarring, is a characteristic feature of the various progressive stages of DN. It can trigger various pathological processes leading to the activation of autophagy, inflammatory responses and a vicious circle of oxidative stress and inflammation.
