Virtual tactile feedback technology based on microcurrent stimulation: current status, challenges and future prospects.

With the rapid development of information technology, virtual reality (VR) technology and metaverse, which highlight personalized experience, have become hot spots in the development of information application industry. Visual, auditory, and tactile systems are the most common sensory systems used by human beings to perceive information about the external environment, facilitated by organs such as the eyes, ears, and skin, making it convenient and natural to interact with the outside world. The integration of virtual tactile feedback technology with audiovisual technology can further enhance the richness of interaction and achieve better immersion experience.

LncRNA linc01194 promotes the progress of endometrial carcinoma by up-regulating SOX2 through binding to IGF2BP1.

Objective: Endometrial carcinoma (EC) is one of the most common gynecological malignant tumors. Our study showed that long non-coding RNA (lncRNA) linc01194 plays an important role in EC. We explored the mechanism of lncRNA linc01194 in EC.

Effects of uteroplacental insufficiency on growth-restricted rats with altered lung development: A metabolomic analysis.

Background: Intrauterine growth restriction (IUGR) is among the most challenging problems in antenatal care. Several factors implicated in the pathophysiology of IUGR have been identified. We aimed to investigate the effect of UPI on lung development by identifying metabolic changes during the first seven days of postnatal life.

snoRNAs: functions and mechanisms in biological processes, and roles in tumor pathophysiology.

Small nucleolar RNAs (snoRNAs), a type of non-coding RNA, are widely present in the nucleoli of eukaryotic cells and play an important role in rRNA modification. With the recent increase in research on snoRNAs, new evidence has emerged indicating that snoRNAs also participate in tRNA and mRNA modification. Studies suggest that numerous snoRNAs, including tumor-promoting and tumor-suppressing snoRNAs, are not only dysregulated in tumors but also show associations with clinical prognosis.

Research progress on the tsRNA classification, function, and application in gynecological malignant tumors.

A large number of small non-coding RNAs derived from tRNAs, called tRNA-derived small RNA (tsRNAs), have been identified by high-throughput RNA sequencing of cell lines. Further research has revealed that they are not produced via random tRNA degradation, but through degradation by specific nuclease cleavages, such as Elac Ribonuclease Z 2 (ELAC2)/RNase Z, RNase L, Dicer, and angiogenin (ANG), the tsRNAs can be classified into the following types based on the location from which they have been derived from the parental tRNA: tRF-1s, tRF-3s, tRF-5s, tiRNA, and tRF-2s/i-tRFs. Moreover, tsRNAs are a type of small RNAs with diverse functions, including gene expression regulation, anti-apoptosis, translation inhibition, participation in epigenetic regulation, initial virus reverse transcription, promote virus replication and cell-to-cell communication.

Insights into roles of METTL14 in tumors.

N6-Methyladenosine (m6A) is considered the most common and endogenous modification of eukaryotic RNAs. Highly conserved in many species, m6A regulates RNA metabolism, cell differentiation, cell circadian rhythm, and cell cycle; it also responds to endogenous and exogenous stimuli and is associated with the development of tumors. The m6A methyltransferase complex (MTC) regulates the m6A modification of transcripts and involves two components, methyltransferase-like enzyme 3 (METTL3) and methyltransferase-like enzyme 14 (METTL14), and other auxiliary regulatory distinct components.

Secreted Frizzled Related Proteins in Cardiovascular and Metabolic Diseases.

Abnormal gene expression and secreted protein levels are accompanied by extensive pathological changes. Secreted frizzled related protein (SFRP) family members are antagonistic inhibitors of the Wnt signaling pathway, and they were recently found to be involved in the pathogenesis of a variety of metabolic diseases, which has led to extensive interest in SFRPs. Previous reports highlighted the importance of SFRPs in lipid metabolism, obesity, type 2 diabetes mellitus and cardiovascular diseases.

Isomalabaricane Triterpenes from the Marine Sponge sp.

The marine sponge of the genus , , , and are characterized chemically by a variety of isomalabaricane triterpenes. This class of compounds drew spotlights in marine lead discovery due to their profound anti-proliferative properties. Further research on exploring its chemical diversity led to the identifications of two new isomalabaricane-type triterpenes rhabdastin H () and rhabdastin I ().

Polydopamine Ultrathin Film Growth on Mica via In-Situ Polymerization of Dopamine with Applications for Silver-Based Antimicrobial Coatings.

The development of polydopamine (PDA) coatings with a nanometer-scale thickness on surfaces is highly desirable for exploiting the novel features arising from the specific structure on the molecular level. Exploring the mechanisms of thin-film growth is helpful for attaining desirable control over the useful properties of materials. We present a systematic study demonstrating the growth of a PDA thin film on the surface of mica in consecutive short deposition time intervals.

Difference in inflammation, atherosclerosis, and platelet activation between coronary artery aneurysm and coronary artery ectasia.

Background: Coronary artery aneurysm (CAA) and coronary artery ectasia (CAE) may be two different types of coronary artery dilatation with unknown etiology. This study aimed to compare the differences between CAA and CAE and to investigate their pathogenesis and the necessity of antiplatelet therapy.

Methods: One hundred patients each with confirmed CAA, CAE, and normal coronary artery (NCA) from September 2017 to July 2019 were included.

Intratracheal Instillation of Stem Cells in Term Neonatal Rats.

Prolonged exposure to high concentrations of oxygen leads to inflammation and acute lung injury, which is similar to human bronchopulmonary dysplasia (BPD). In premature infants, BPD is a major complication despite early use of surfactant therapy, optimal ventilation strategies, and noninvasive positive pressure ventilation. Because pulmonary inflammation plays a crucial role in the pathogenesis of BPD, corticosteroid use is one potential treatment to prevent it.

Multidrug-resistance Acinetobacter baumannii pneumonia in a rheumatoid arthritis patient receiving tumor necrosis factor inhibitor: A case report.

Introduction: Multidrug-resistant Acinetobacter baumannii (MDRAB) pneumonia with severe sepsis in a patient with rheumatoid arthritis (RA), who is predisposed after treatment with tumor necrosis factor inhibitor (TNFI), is a rare severe infection and can be successfully treated with prompt antibiotics.

Case Presentation: A 75-year-old woman was diagnosed with RA >30 years previously. After inadequate treatment responses to conventional disease-modifying antirheumatic drugs (DMARDs), she developed progressive RA, including swollen joints in both hands, and had a high disease activity score of 4.

Does nephrotic syndrome without chronic kidney disease increase the risk of Parkinson's disease and secondary parkinsonism? A nationwide population-based study in Taiwan.

Objectives: Previous research has shown that patients with nephrotic syndrome (NS) have a higher risk of cognitive impairment, dementia or neurodegenerative disorder. The present study aimed to examine a relationship, if any exists between NS and Parkinson's disease (PD), a neurodegenerative disorder and secondary parkinsonism (sPS).

Treatment of multiple refractory ankle ulcerations in thromboangiitis obliterans: A case report.

Rationale: Thromboangiitis obliterans (TAOs, or Buerger's disease) present as a non-atherosclerotic segmental occlusive vasculitis within medium- and small-sized blood vessels. TAO frequently occurs in young adults and is associated with cigarette smoking. At present, there are no accurately defined treatments for TAO.

Acute appendicitis complicated with necrotizing fasciitis in a patient with adult-onset Still's disease: A case report.

Rationale: Adult-onset Still disease (AOSD) is a rare systemic inflammatory disease of unknown etiology characterized by evanescent salmon-pink rash, spiking fever, arthralgia/ arthritis, and lymphadenopathy. AOSD sometimes was fatal when it is complicated by macrophage activation syndrome (MAS) or hemophagocytic lymphohistiocytosis (HLH). Nonetheless, the literature provides no recommendations for treatment of AOSD patients with severe sepsis.
