Article Synopsis
  • * The study investigated the potential protective effects of water-extracted Artemisia argyi (AA) on heart cells (H9c2) exposed to DOX, focusing on specific cellular signaling pathways (IGF-IIR/Drp1/GATA4).
  • * Results indicated that AA extract not only reduced damage caused by DOX but also mitigated symptoms of cardiac toxicity, suggesting it could be a promising option to protect the heart during cancer treatment.

Cardiovascular disease is one of the leading causes of death worldwide and has a high prevalence. Insulin-like growth factor-II receptor α (IGF-IIRα) acts as a stress-inducible negative regulator. This study focused on the substantial impact of heightened expression of IGF-IIRα in cardiac myoblasts and its association with the exacerbation of cardiac dysfunction.

Bladder cancer stands as a prevailing neoplasm among men globally, distinguished for its pronounced malignancy attributed to invasiveness and metastatic proclivity. Tannic acid (TA), an organic compound in many plants, has garnered recent attention for its discernible anti-mutagenic attributes. This investigation endeavored to scrutinize the repercussions of TA on grade II bladder cancer, with a concerted focus on unraveling its anti-cancer mechanisms.

Article Synopsis
  • The skin acts as a crucial barrier for protection against mechanical damage, pathogens, and UV radiation while maintaining physiological balance.
  • The study explores how low-concentration imiquimod can enhance skin barrier function by promoting melanin production, as shown in animal and cell model experiments.
  • Findings suggest that imiquimod increases melanin synthesis without causing inflammation, highlighting its potential as a treatment to improve skin barrier functions by regulating pigmentation.

Aging-associated cardiovascular diseases depend on the longitudinal deterioration of stem cell dynamics. The entire mechanism behind it is not completely understood. However, many studies suggest that endocrine pathways, particularly the insulin-like growth factor-1(IGF1) signaling pathway are involved in cardioprotection, especially in stem-cell treatments.

CPT-11 is one of the drugs employed in colorectal cancer treatment and has faced challenges in the form of resistance. The insulin-like growth factor 1 receptor is a tyrosine kinase receptor that mediates cancer cell survival and drug resistance. It is frequently overexpressed in colorectal cancer and has previously been identified as a microRNA target.

Pathological cardiac hypertrophy is a considerable contributor to global disease burden. Chinese herbal medicine (CHM) has been used to treat cardiovascular diseases since antiquity. Enhancing stem cell-mediated recovery through CHM represents a promising approach for protection against doxorubicin (Dox)-induced cardiac hypertrophy.

Cardiovascular diseases in post-menopausal women are on a rise. Oxidative stress is the main contributing factor to the etiology and pathogenesis of cardiovascular diseases. Diosgenin, a member of steroidal sapogenin, is structurally similar to estrogen and has been shown to have antioxidant effects.

Fibroblast-like synoviocytes accumulation, proliferation and activation, and the subsequent inflammatory mediators production play a key role in the progression of rheumatoid arthritis (RA). It is well established that Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling triggers inflammation, and induces cytokine levels in RA. Ohwia caudata have long been used against many disorders.

This study evaluated the risks of childhood acute bronchitis and bronchiolitis (CABs) for children with asthma or allergic rhinitis (AR). Using insurance claims data of Taiwan, we identified, from children of ≤12 years old in 2000-2016, cohorts with and without asthma (N = 192,126, each) and cohorts with and without AR (N = 1,062,903, each) matched by sex and age. By the end of 2016, the asthma cohort had the highest bronchitis incidence, AR and non-asthma cohorts followed, and the lowest in the non-AR cohort (525.

Background: Diabetic cardiomyopathy is a progressive disease caused by inexplicit mechanisms, and a novel factor, insulin-like growth factor II receptor-α (IGF-IIRα), may contribute to aggravating its pathogenesis. We hypothesized that IGF-IIRα could intensify diabetic heart injury.

Methods And Results: To demonstrate the potential role of IGF-IIRα in the diabetic heart, we used (SD-TG [IGF-IIRα]) transgenic rat model with cardiac-specific overexpression of IGF-IIRα, along with H9c2 cells, to study the effects of IGF-IIRα in the heart under hyperglycemic conditions.

Parkinson's disease (PD) is a common disorder attributed to the loss of midbrain dopamine (mDA) neurons and reduced dopamine secretion. Currently, the treatment regimes for PD comprise deep brain stimulations, however, it attenuates the PD progression marginally and does not improve neuronal cell death. We investigated the function of Ginkgolide A (GA) to reinforce Wharton's Jelly-derived mesenchymal stem cells (WJMSCs) for treating the model of PD.

Oxaliplatin-based therapy is used as a first-line drug to treat metastatic colorectal cancer. However, long-term and repeated drug treatment resulted in drug resistance and the failure of chemotherapy. Various natural compounds were previously reported to act as chemosensitizers to reverse drug resistance.

Objectives: Patient and provider-facing screening tools for social determinants of health have been explored in a variety of contexts; however, effective screening and resource referral remain challenging, and less is known about how patients perceive chatbots as potential social needs screening tools. We investigated patient perceptions of a chatbot for social needs screening using three implementation outcome measures: acceptability, feasibility, and appropriateness.

Methods: We implemented a chatbot for social needs screening at one large public hospital emergency department (ED) and used concurrent triangulation to assess perceptions of the chatbot use for screening.

Parkinson's disease (PD), a chronic and progressive neurodegenerative disease, can reduce the population of dopaminergic neurons in the substantia nigra. The cause of this neuronal death remains unclear. 1-Methyl-4-phenylpyridinium ion (MPP+) is a potent neurotoxin that can destroy dopaminergic (DA) neurons and promote PD.

Introduction: As the significance of social workers (SW) in improving healthcare delivery in the emergency department (ED) continues to expand, emergency physicians will increasingly be expected to effectively partner with SWs in both academic and community settings. In this scoping review we sought to provide evidence-based recommendations for effective emergency clinician educational interventions on how to incorporate SWs in the ED to address health-related social needs while also identifying directions for future research.

Methods: We conducted a systematic literature review of publications in PubMed, CINAHL, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and APA PsycINFO.

Studies have associated the human respiratory syncytial virus which causes seasonal childhood acute bronchitis and bronchiolitis (CABs) with climate change and air pollution. We investigated this association using the insurance claims data of 3,965,560 children aged ≤ 12 years from Taiwan from 2006−2016. The monthly average incident CABs increased with increasing PM2.

This study reports the effect of cardiac-specific insulin-like growth factor-II receptor α (IGF-IIRα) overexpression on the development of liver dysfunction in transgenic rats via STZ-induced diabetic hepatocyte damage. The cardio-hepatic syndrome comprises a number of heart and liver illnesses in which an acute or chronic disease in one organ can lead to acute or chronic disease in the other. However, the molecular mechanism involved in such a set of conditions is unclear.

Aging is accompanied by functional loss of many cellular pathways, creating an increased risk of many age-related complications (ARC). Aging causes stem cell exhaustion with a concomitant increase in cellular dysfunction. Recently, interest in senotherapeutics has been growing rapidly to promote healthy aging and as an intervention for ARCs.

Oxidized low-density lipoprotein (ox-LDL) is a type of modified cholesterol that promotes apoptosis and inflammation and advances the progression of heart failure. Leucine-zipper and sterile-α motif kinase (ZAK) is a kinase of the MAP3K family which is highly expressed in the heart and encodes two variants, ZAKα and ZAKβ. Our previous study serendipitously found opposite effects of ZAKα and ZAKβ in which ZAKβ antagonizes ZAKα-induced apoptosis and hypertrophy of the heart.
