Background: Activating the ubiquitin-proteasome system to dismantle disease- related proteins such as tau, β-amyloid, APP, and α-synuclein is an important focus in the research of neurodegenerative proteinopathy. By analyzing the serum RNA extracted from wild-type and Alzheimer's disease (AD) transgenic mice at different ages (4, 8, and 12 months), this study revealed a new protective role of FBXL16 in AD, primarily through facilitating the degradation of disease-related proteins via the ubiquitin proteasome system.
Methods: Proteomic analysis were conducted using protein lysates from HEK293 cells overexpressing FBXL16 to identify potential interacting proteins that interact with FBXL16.
Recent advancements in the field of medical artificial intelligence (AI) have led to the widespread adoption of foundational and large language models. This review paper explores their applications within medical AI, introducing a novel classification framework that categorizes them as disease-specific, general-domain, and multi-modal models. The paper also addresses key challenges such as data acquisition and augmentation, including issues related to data volume, annotation, multi-modal fusion, and privacy concerns.

Consequently, identifying key therapeutic GPCRs targets for CNS-related diseases is garnering immense interest in research labs and pharmaceutical companies. However, using GPCRs drugs for treating neurodegenerative diseases has limitations, including side effects and uncertain effective time frame.

Many studies have confirmed or validated the efficacy and safety of FIR in various diseases, benefiting from new insights into FIR mechanisms and the excellent performance of many applications. However, the lack of consensus on the biological effects and therapeutic parameters of FIR limits its practical applications in the clinic.

Previous studies have confirmed Caulerpa chemnitzia polysaccharides (CRVP) have immunomodulatory activity, but the immunomodulatory mechanism of CRVP in macrophages has not been thoroughly explored yet. In our research, we found that CRVP has outstanding immunomodulatory activity in macrophages, which is reflected in promoting cell proliferation, upregulating cytokines (IL-1β, IL-6, and TNF-α) expression, and increasing NO and ROS levels.

In this investigation, a novel polysaccharide was extracted from the culture medium of the marine fungus Aspergillus medius SCAU-236. Compositional analysis revealed a structure composed of glucose units with (1,4)-α-D-Glcp, (1,3,4)-β-D-Glcp, and (1,4,6)-α-D-Glcp, along with side chains of 1-α-D-Glcp linked to carbon 6 of (1,4,6)-α-D-Glcp and carbon 3 of (1,3,4)-β-D-Glcp.

We explored the possible p53 aggregation formation mechanisms commonly occur after ischemic stroke, such as hypoxia and the presence of reactive oxygen species (ROS). The angiogenic pathways involving p53 mainly occur in nucleus or cytoplasm, with one exception that occurs in mitochondria.

The aim of this study was to determine and quantify the predictive performance of depressive symptoms in the second trimester for postnatal depressive symptoms and to raise awareness of psychosocial problems. This was a prospective longitudinal study. The experimental group comprised Chinese women who completed the Edinburgh Postnatal Depression Scale (EPDS) two times (once during the second trimester and once at 6-8 weeks postdelivery) at Fong Son Tong Health Center (CSSL), Macau.

Background: In the primary care setting in Macau, type 2 diabetes mellitus (T2DM) is the seventh most common reason for consultation. Inadequate glycaemic control constitutes a major public health problem and is associated with premature death and disability and decreased quality of life. Moreover, this condition substantially increases healthcare expenditures.

We also identified the FANCM-related DNA helicase Fml1 as a potential suppressor of IFSA.

Replication fork barriers are a commonly encountered problem, which can cause fork collapse and act as hotspots for replication termination. Collapsed forks can be rescued by homologous recombination, which restarts replication.

Bacteriophage T5 has a 120 kb double-stranded linear DNA genome encoding most of the genes required for its own replication. This lytic bacteriophage has a burst size of ∼500 new phage particles per infected cell, demonstrating that it is able to turn each infected bacterium into a highly efficient DNA manufacturing machine. To begin to understand DNA replication in this prodigious bacteriophage, we have characterized a putative helicase encoded by gene D2.
