Patent landscape of small molecule inhibitors of METTL3 (2020-present).

Introduction: Methyltransferase-like protein 3 (METTL3), in complex with METTL14, is the key 'writer' protein for RNA mA methylation, accounting for almost all mRNA mA modifications. Recent studies reveal that METTL3 is implicated in the development and progression of various types of cancers. Targeting METTL3 with small molecule inhibitors represents a promising therapeutic strategy for cancer.

A Milk Extracellular Vesicle-Based Nanoplatform Enhances Combination Therapy Against Multidrug-Resistant Bacterial Infections.

The increasing occurrence of infections caused by multidrug-resistant (MDR) bacteria drives the need for new antibacterial drugs. Due to the current lack of antibiotic discovery and development, new strategies to fight MDR bacteria are urgently needed. Efforts to develop new antibiotic adjuvants to increase the effectiveness of existing antibiotics and design delivery systems are essential to address this issue.

Gossypium spp. pigment glands are a good model for studying plant secretory cavity structures. GoPGF (GOSSYPIUM PIGMENT GLAND FORMATION) is a well-characterized master transcription factor that controls gland formation in cotton; however, little is known about its transcriptional regulation.

High-Performance Boiling Surfaces Enabled by an Electrode-Transpose All-Electrochemical Strategy.

High-performance boiling surfaces are in great demand for efficient cooling of high-heat-flux devices. Although various micro-/nano-structured surfaces have been engineered toward higher surface wettability and wickability for enhanced boiling, the design and fabrication of surface structures for realizing both high critical heat flux (CHF) and high heat transfer coefficient (HTC) remain a key challenge. Here, a novel "electrode-transpose" all-electrochemical strategy is proposed to create superhydrophilic microporous surfaces with higher dendrites and larger pores by simply adding an electrochemical etching step prior to the multiple electrochemical deposition steps.

Lactylation of Histone H3k18 and Egr1 Promotes Endothelial Glycocalyx Degradation in Sepsis-Induced Acute Lung Injury.

Circulating lactate is a critical biomarker for sepsis-induced acute lung injury (S-ALI) and is strongly associated with poor prognosis. However, whether elevated lactate directly promotes S-ALI and the specific mechanism involved remain unclear. Here, this work shows that lactate causes pulmonary endothelial glycocalyx degradation and worsens ALI during sepsis.

The Current Advances in Design Strategy (Indirect Strategy and Direct Strategy) for Type-I Photosensitizers.

Type-I photosensitizers (PSs) are among the most potential candidates for photodynamic therapy (PDT), as their low dependence on oxygen endow them with many advantages for treating hypoxic tumor. However, most of the reported type-I PSs have a contingency of molecular design, because electron transfer (ET) reaction is more difficult to achieve than energy transfer (EET) process. Therefore, it is urgent to understand molecular design mechanisms for type-I PSs.

Microglia heterogeneity during neuroinflammation and neurodegeneration in the mouse retina.

Microglia play important roles in maintaining homeostasis and immunoreactive defense in the central nervous system including retina. To accomplish such a wide range of functions, microglia are highly heterogeneous. Dark microglia (DM) were recently identified by electron microscopy (EM).

In-situ Growth of Metallocluster inside Heterometal-organic Cage to Switch Electron Transfer for Targeted CO2 Photoreduction.

Construction of metal-organic cages (MOCs) with internal modifications is a promising avenue to build enzyme-like cavities and unlocking the mystery of highly catalytic activity and selectivity of enzymes. However, current interests are mainly focused on single-metal-node cages, little achievement has been expended to metalloclusters-based architectures, and the in situ endogenous generation of metal clusters. Herein, based on the hard-soft-acids-bases (HSAB), the metalloclusters-based heterometallic MOC (Cu3VMOP) constructed of [Cu3OPz3]+ and [V6O6(OCH3)9(SO4)(CO2)3]2- clusters was obtained by one-pot method.

Palladium-Catalyzed Enantioselective Cyclization of 1,6-Enynes to Access Chiral γ-Butyrolactam.

A palladium-catalyzed asymmetric chlorocyclization of 1,6-enynes has been described. Controlling the chloride ion concentration in the system by substrate design is the key to achieving asymmetric chlorinated cyclization. In the presence of Pd(PhCN)Cl and chiral phosphoramidite ligands, the reaction accesses diverse chiral ()-α-chloromethylene-γ-butyrolactams with excellent selectivity and enantioselectivity.

Switch-Type Electrochemiluminescence Aptasensor for AFB1 Detection Based on CoS Quantum Dots Encapsulated in Co-LDH and a Ferrocene Quencher.

Among the various aflatoxin B1 (AFB1) assays, performing accurate detection is difficult because false positives and false negatives are frequent due to limited sensitivity, expensive equipment, or inadequate pretreatment during operation. Here, an "off-on" switch-type electrochemiluminescence (ECL) aptasensor armed with cobalt-sulfur quantum dots was encapsulated in hollow cobalt-layered double hydroxide nanocages as an enhanced luminescent probe (Co-LDH@QDs), and a ferrocene-modified aptamer (Fc-APT) was used as a luminescent quencher. In general, when Fc-APT was hybridized with complementary DNA modified with a DNA nanotetrahedron, electron transfer between ferrocene and Co-LDH@QDs was facilitated, leading to efficient quenching of the ECL intensity into an "off" state in the absence of AFB1.

Relation of 91 Circulating Inflammatory Proteins to Nonalcoholic Fatty Liver Disease: A Two-Sample Mendelian Randomisation Study.

Background: Mutations commonly occur in cancer cells, arising neoantigen as potential targets for personalized immunotherapy of lung adenocarcinoma (LUAD). However, the substantial heterogeneity observed among individuals and distinct foci within the same patient presents significant challenges in formulating immunotherapy strategies. The aim of the work is to characterize the mutation pattern and identify neopeptides across different patients and diverse foci within the same patients with LUAD.

Objective: To investigate the effects of perceived sports environment on Chinese college students' sport gains, and to verify the mediating roles of physical activity behavior and self-efficacy in sport learning.

Methods: A survey of 2,207 Chinese university students was conducted using the sport environment perception scale, sport gain scale, physical activity behavior scale, and sport learning self-efficacy scale.

LncRNA EGFR‑AS1 promotes lung cancer cell proliferation, invasion and metastasis via regulation of miR‑449a/HDAC1.

There is increasing evidence that long non-coding (lnc)RNA EGFR-AS1 is involved in the development of numerous types of cancer, including non-small-cell lung cancer (NSCLC). The Cancer Genome Atlas (TCGA) demonstrates that EGFR-AS1 is highly expressed in NSCLC. Downregulation of EGFR-AS1 in A549 and PC9 NSCLC cells demonstrates inhibition of NSCLC proliferation, invasion and metastasis.

3D convolutional neural network based on spatial-spectral feature pictures learning for decoding motor imagery EEG signal.

Non-invasive brain-computer interfaces (BCI) hold great promise in the field of neurorehabilitation. They are easy to use and do not require surgery, particularly in the area of motor imagery electroencephalography (EEG). However, motor imagery EEG signals often have a low signal-to-noise ratio and limited spatial and temporal resolution.

A survey of attitudes towards the curriculum for clinical medicine postgraduates pursuing professional master's degrees: perspectives of supervisors and students.

Background: Based on the recommendation of the Ministry of Education in China to differentiate between "academic" and "professional" degrees, medical schools offer both professional and academic degrees for postgraduates. In China, clinical postgraduates who are pursuing a professional master's degree also participate in standardised residency training (SRT). However, little attention has been given to feedback from students and supervisors regarding postgraduate curricula.
