MHCI trafficking signal-based mRNA vaccines strengthening immune protection against RNA viruses.

The major histocompatibility complex class I (MHCI) trafficking signal (MITD) plays a pivotal role in enhancing the efficacy of mRNA vaccines. However, there was a lack of research investigating its efficacy in enhancing immune responses to RNA virus infections. Here, we have developed an innovative strategy for the formulation of mRNA vaccines.

Nonviral targeted mRNA delivery: principles, progresses, and challenges.

Messenger RNA (mRNA) therapeutics have garnered considerable attention due to their remarkable efficacy in the treatment of various diseases. The COVID-19 mRNA vaccine and RSV mRNA vaccine have been approved on the market. Due to the inherent nuclease-instability and negative charge of mRNA, delivery systems are developed to protect the mRNA from degradation and facilitate its crossing cell membrane to express functional proteins or peptides in the cytoplasm.

Fetal hepatocytes protect the HSPC genome via fetuin-A.

The maintenance of genomic integrity in rapidly proliferating cells is a substantial challenge during embryonic development. Although numerous cell-intrinsic mechanisms have been revealed, little is known about genome-protective effects and influences of developmental tissue microenvironments on tissue-forming cells. Here we show that fetal liver hepatocytes provide protection to haematopoietic stem and progenitor cell (HSPC) genomes.

The development and application of cleavage under targets and tagmentation (CUT&Tag) technology.

The regulation of chromatin structure and gene transcription in eukaryotic cells is an involved process mediated by histone modifications, chromatin-binding proteins, and transcription factors. Studying the distribution of histone modifications and transcription factors at the whole-genome level is crucial for understanding the mechanisms of gene transcription. Cleavage under targets and tagmentation (CUT&Tag) is a novel chromatin analysis method that has rapidly gained popularity in the field of epigenetics since its introduction.

Impact of Family Mutual Aid System for Personal Medical Insurance Accounts on Paediatric Patients' Outpatient Utilisation Patterns and Costs: a difference-in-differences analysis.

This study explores the effect of the transformation of paediatric healthcare through the implementation of the Family Mutual Aid System (FMAS) for personal medical insurance accounts, among paediatric patients at a children's hospital (Hospital A in Shanghai, China). We conducted a cohort study in the endocrinology department of Hospital A from August 2021 to July 2023 to assess the impact of the FMAS enrolment on patients' annual outpatient visits, annual outpatient expenditures, and the allocation of these costs among the Basic Medical Insurance Pooling Fund and patients' out-of-pocket (OOP) expenses, with a further subdivision into online and offline consultations. Analysis employed a weighted Difference-in-Differences approach within a fixed-effects model following Propensity Score Matching.

Genome-Wide Development and Characterization of Microsatellite Markers in the Great Web-Spinning Sawfly .

The great web-spinning sawfly is notorious for damaging forests across the Palearctic region. At present, uncertainties persist regarding its intraspecies variation and presumed subspecies. To use as tools for future studies, herein we developed genome-wide microsatellite markers for .

SETD3-mediated histidine methylation of MCM7 regulates DNA replication by facilitating chromatin loading of MCM.

The minichromosome maintenance complex (MCM) DNA helicase is an important replicative factor during DNA replication. The proper chromatin loading of MCM is a key step to ensure replication initiation during S phase. Because replication initiation is regulated by multiple biological cues, additional changes to MCM may provide better understanding towards this event.

Replication-coupled inheritance of chromatin states.

During the development of eukaryote, faithful inheritance of chromatin states is central to the maintenance of cell fate. DNA replication poses a significant challenge for chromatin state inheritance because every nucleosome in the genome is disrupted as the replication fork passes. It has been found that many factors including DNA polymerases, histone chaperones, as well as, RNA Pol II and histone modifying enzymes coordinate spatially and temporally to maintain the epigenome during this progress.

Storage practice and wastage of pharmaceuticals in Chinese urban-dwelling households: Description of urban-dwelling households.

At-home storage of medications could pose a threat to public health and the environment if not handled appropriately. Excessive storage also creates health care and economic burdens. This study investigated storage practices, waste, and their determinants in China.

AfSwi6 Regulates the Stress Response, Chlamydospore Production, and Pathogenicity in the Nematode-Trapping Fungus .

Nematode-trapping (NT) fungi are a major resource for controlling parasitic nematodes. , as a typical NT fungus, can capture nematodes by producing three-dimensional nets. The APSES transcription factor plays a vital role in fungal growth and the pathogenicity of pathogens.

Proximity induced charge density wave in a graphene/1T-TaS heterostructure.

The proximity-effect, whereby materials in contact appropriate each other's electronic-properties, is widely used to induce correlated states, such as superconductivity or magnetism, at heterostructure interfaces. Thus far however, demonstrating the existence of proximity-induced charge-density-waves (PI-CDW) proved challenging. This is due to competing effects, such as screening or co-tunneling into the parent material, that obscured its presence.

J147 treatment protects against traumatic brain injury by inhibiting neuronal endoplasmic reticulum stress potentially via the AMPK/SREBP-1 pathway.

Endoplasmic reticulum (ER) stress is recognized as a crucial contributor to the progression of traumatic brain injury (TBI) and represents a potential target for therapeutic intervention. This study aimed to assess the potential of J147, a novel neurotrophic compound, in alleviating ER stress by modulating related signaling pathways, thereby promoting functional recovery in TBI. To this end, adult mice underwent controlled cortical impact (CCI) injury to induce TBI, followed by oral administration of J147 one-hour post-injury, with daily dosing for 3 to 7 days.

Cryogen-free modular scanning tunneling microscope operating at 4-K in high magnetic field on a compact ultra-high vacuum platform.

One of the daunting challenges in modern low temperature scanning tunneling microscopy (STM) is the difficulty of combining atomic resolution with cryogen-free cooling. Further functionality needs, such as ultra-high vacuum (UHV), high magnetic field (HF), and compatibility with μm-sized samples, pose additional challenges to an already ambitious build. We present the design, construction, and performance of a cryogen-free, UHV, low temperature, and high magnetic field system for modular STM operation.
