The skin, as the largest organ in the human body, serves as the primary physical barrier and plays a crucial role in the immune defense process. Immune-related skin diseases encompass a spectrum of complex dermatological conditions characterized by aberrant immune responses, including the production of autoantibodies and dysregulation of inflammatory mediators. Growing evidence suggest a heightened prevalence of comorbid neuropsychiatric disorders among patients with immune-related skin diseases, indicative of potential shared pathogenesis.

The precise mechanism by which sleep disturbances elevate Aβ levels is unclear. Our previous study has demonstrated that knocking down encoding gene Grin2a of astrocytic N-methyl-D-aspartate (NMDA) receptors GluN2A subunit could aggravate sleep deprivation (SD)-induced elevation of Aβ, indicating a protective role of astrocytic GluN2A in SD; but the underlying mechanism needs to be further elucidated.

To explore how balance and hamstring training improve individuals with nonspecific lower back pain (NSLBP). A total of 26 NSLBP people were randomly allocated into either the experimental group (EG) (n = 13) or the control group (CG) (n = 13).

Despite local therapeutic interventions remaining the primary mode of treatment, the dynamic nature of the oral cavity, characterized by continuous muscular activity and salivary secretion, poses barriers to sustained drug retention and thereby limits therapeutic efficacy. To address this issue, an approach has been devised that aims to facilitate transdermal delivery of bioactive components to promote the healing of diabetic oral ulcers.

We conducted a simulation experiment to examine whether and how legumes influence the response of coexisting grass to salt stress. We compared the effects of salt stress on the plant biomass, root cell viability, antioxidant enzyme activities, soil extracellular enzyme activities and microbial functional gene abundances associated with N and phosphorus (P) cycling between pure grass communities and legume-grass mixtures.

Transdermal drug delivery presents a compelling alternative to both needle injection and oral ingestion of medication, as it enhances patient adherence and convenience through its non-invasive and painless administration method. The use of microneedles penetrates the barrier of the stratum corneum, facilitating the sustained delivery of drugs across the skin. However, their efficacy has been limited by the slow diffusion of molecules and often requires external triggers.

The automated diagnosis of low-resolution and difficult-to-recognize breast ultrasound images through multi-modal fusion holds significant clinical value. However, prevailing fusion methods predominantly rely on image modalities, neglecting the textual pathology information, and only benign and malignant diagnosis of breast tumors is not satisfying for clinical applications. Consequently, this paper proposes a novel multi-modal fusion interactive diagnostic framework, termed the MIC framework, to achieve the multi-label classification of breast cancer, namely benign-malignant classification and breast imaging reporting and data system (BI-RADS) 3, 4a, 4b, 4c, and 5 gradings.

In laparoscopic surgery, a 30° lens is frequently used to obtain a wider field of view. However, it is difficult for inexperienced surgeons to maintain the horizontal state of the image in laparoscopic camera navigation (LCN). If there is a great deviation in the camera's horizontal axis, it may result in ambiguous anatomical recognition, which could impair patient safety.

The role of adipose tissue in vitiligo remains unclear. To investigate the role of adipose tissue in the pathogenesis of vitiligo, 50 patients newly diagnosed with vitiligo and 40 age- and sex-matched healthy controls were enrolled, and fat mass and distribution using dual-energy X-ray absorptiometry (DXA) and serum adipokine levels using enzyme-linked immunosorbent assay were assessed.

Chemotherapy treatment outcomes are severely restricted by multidrug resistance (MDR), in which tumors develop a multiple cross-resistance toward drug involving the pump and nonpump resistance mechanisms, resulting in drug efflux and defending against drug toxicity. Herein, we constructed a pH and near infrared (NIR) light responsive nanomedicine DOX@FG based on gold nanorods (GNRs) that demonstrated the potential to improve chemotherapy outcomes by overcoming MDR. DOX@FG was constructed by conjugating folic acid (FA) and doxorubicin (DOX) derivatives onto GNRs, where the DOX derivatives possessed an acid-labile hydrazone bond.

However, the concrete mechanisms of N6-methyladenosine (m6A) modification of circRNAs in PCa remain unclear. In our study, we identified circRPS6KC1, a novel and up-regulated circular RNA in PCa, through circRNA sequencing.

Deep learning technology is widely used in the field of medical imaging. Among them, Convolutional Neural Networks (CNNs) are the most widely used, and the quality of the dataset is crucial for the training of CNN diagnostic models, as mislabeled data can easily affect the accuracy of the diagnostic models. However, due to medical specialization, it is difficult for non-professional physicians to judge mislabeled medical image data.

Background: Fibrosis is a tissue damage repair response caused by multiple pathogenic factors which could occur in almost every apparatus and leading to the tissue structure damage, physiological abnormality, and even organ failure until death. Up to now, there is still no specific drugs or strategies can effectively block or changeover tissue fibrosis. JNKs, a subset of mitogen-activated protein kinases (MAPK), have been reported that participates in various biological processes, such as genetic expression, DNA damage, and cell activation/proliferation/death pathways.
