Comparative Proteomics Study on Human High-metastatic Large Cell Lung Cancer Cell Lines with Differential Metastatic Potential

Background and Objective Lung cancer is not only the most dangerous threating tumor to humans health and life, but also a malignant tumor with poor prognosis. It has been well-known     

Alterations and Its Mechanisms of Wnt Signal Pathway in Human High-matastatatic Large Cell Lung Cancer Cell Line L9981 by Transfecting with Nm23-H1 Gene

Backgroud and Objective Tumor metastasis is not only the malignant marker and characteristics of lung cancer, but also the main cause of failure to cure and lose their life of the patients     

Is hypertension associated with arthritis? The United States national health and nutrition examination survey 1999–2018

ObjectiveHypertension and arthritis are two common diseases in the general population, with multiple common risk factors. This study aimed to assess the association between hypertension (HTN) and arthritis.Patients and methodsThis cohort study included 48,372 eligible non-pregnant participants aged ≥ 20 years who had valid data on hypertension and arthritis from the National Health and Nutrition Examination Survey (NHANES) 1999–2018. The association between hypertension and arthritis was studied by logistic regression, adjusting for demographics, socioeconomic factors, excess sodium intake, physical activity, ever smoking, diabetes status and body mass index (BMI).ResultsAmong the participants, 48.0% (95% CI: 47.2–48.9) had hypertension and 24.5% (95% CI: 23.8–25.3) had self-reported arthritis. Hypertension was associated with arthritis [OR = 2.90, (95% CI: 2.74–3.07), p < 0.01], which remained significant [OR = 1.27, (95% CI:1.18–1.37), p < 0.01] after adjustments. Stratified by the types of arthritis, the association remained significant in rheumatoid arthritis (RA) [OR = 1.25, (95% CI: 1.11–1.41), p < 0.01] and osteoarthritis (OA) [OR = 1.32, (95% CI: 1.16–1.50); p < 0.01]. There was no clear association between hypertension and OA in participants aged 60 years old and above [OR = 1.08, (95% CI: 0.92–1.26); p = 0.37].ConclusionsIn this large nationally representative survey over 20 years, arthritis, including both RA and OA, was strongly associated with hypertension. Our study demonstrates a need for hypertension screening and blood control among patients with arthritis.

Key Messages

• Arthritis was associated with hypertension.
• Both rheumatoid arthritis and osteoarthritis are strongly associated with hypertension.
• There is an urgency for hypertension screening and blood control among patients with arthritis.

     

IgE-neutralizing UB-221 mAb,distinct from omalizumab and ligelizumab,exhibits CD23-mediated IgE downregulation and relieves urticaria symptoms

Over the last 2 decades, omalizumab is the only anti-IgE antibody that has been approved for asthma and chronic spontaneous urticaria (CSU). Ligelizumab, a higher-affinity anti-IgE mAb and the only rival viable candidate in late-stage clinical trials, showed anti-CSU efficacy superior to that of omalizumab in phase IIb but not in phase III. This report features the antigenic-functional characteristics of UB-221, an anti-IgE mAb of a newer class that is distinct from omalizumab and ligelizumab. UB-221, in free form, bound abundantly to CD23-occupied IgE and, in oligomeric mAb-IgE complex forms, freely engaged CD23, while ligelizumab reacted limitedly and omalizumab stayed inert toward CD23; these observations are consistent with UB-221 outperforming ligelizumab and omalizumab in CD23-mediated downregulation of IgE production. UB-221 bound IgE with a strong affinity to prevent FcԑRI-mediated basophil activation and degranulation, exhibiting superior IgE-neutralizing activity to that of omalizumab. UB-221 and ligelizumab bound cellular IgE and effectively neutralized IgE in sera of patients with atopic dermatitis with equal strength, while omalizumab lagged behind. A single UB-221 dose administered to cynomolgus macaques and human IgE (ε, κ)–knockin mice could induce rapid, pronounced serum-IgE reduction. A single UB-221 dose administered to patients with CSU in a first-in-human trial exhibited durable disease symptom relief in parallel with a rapid reduction in serum free-IgE level.     

Effects of luminance combinations on the characteristics of the global flash multifocal electroretinogram (mfERG)

Purpose  

This study aims to ascertain the characteristics of the response triggered by the global flash multifocal electroretinogram (MOFO mfERG) under various combinations of global and focal flash luminance, and to determine the optimal conditions for this measurement.
