Centella asiatica, a traditional medicinal plant, possesses potent antioxidant activity and may therefore prevent cellular aging exert antiapoptotic effects. However, these effects remain to be fully elucidated. This study aimed investigate the protective of C. asiatica extract against senescence apoptosis caused by hydrogen peroxide (H2O2)-induced oxidative stress in human epidermal keratinocytes (HaCaT cells). To evaluate H2O2 on HaCaT cells, we measured cell viability as marker death;...

Inhaled nitric oxide (NO) has been shown to reduce the mean pulmonary artery pressure (mPAP) and improve PaO2 in patients with acute respiratory failure undergoing oxygen (O2) therapy. However, inhaled NO reduced hypertension without improving chronic obstructive disease (COPD). This study was intended compare hemodynamic gas exchange responses during inhalation of or O2 those observed combined 10 spontaneously breathing COPD patients. Hemodynamic blood parameters were measured after...

In the rituximab era, several large studies have suggested that full-dose plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) might be best treatment for patients with diffuse B-cell lymphoma (DLBCL) aged 60 years older. However, it remains unclear whether this is also case those 70 Previously untreated DLBCL older (elderly) were treated R-70%CHOP, younger than (younger) R-CHOP every 3 weeks, a total of 6-8 cycles. Complete remission (CR) rates in elderly versus 75 vs....

Abstract Background Hay fever is a common allergic disease, with an estimated worldwide prevalence of 14.4% and variety symptoms. This study assessed the minimal clinically important difference (MCID) nasal symptom score (NSS), non‐nasal (NNSS), total symptoms (TSS) for app‐based hay‐fever monitoring. Methods MCIDs were calculated based on data from previous large‐scale, crowdsourced, cross‐sectional using AllerSearch, in‐house smartphone application. determined anchor‐based...

Abstract Introduction We studied the mortality risk of long term and new antipsychotic drug use in Alzheimer's disease (AD) patients Japan to determine improved treatment protocols. Methods This 24‐week prospective cohort study included 10,079 Japanese AD (female, 69%; average age, 81 years) under routine clinical care 357 medical sites. The medication history was varied (63.7% were long‐term users). Mortality rates odds ratio analyzed (initial 10 weeks from 11–24 weeks). Results exposed...

Using traditional patient-reported outcomes (PROs), such as paper-based questionnaires, is cumbersome in the era of web-based medical consultation and telemedicine. Electronic PROs may reduce burden on patients if implemented widely. Considering promising reports DryEyeRhythm, our in-house mHealth smartphone app for investigating dry eye disease (DED) electronic Ocular Surface Disease Index (OSDI) should be evaluated compared to determine their equivalency.

The aim of this study was to determine whether low-dose inhalation nitric oxide (NO) improves pulmonary haemodynamics and gas exchange in patients with stable idiopathic fibrosis (IPF). investigation included 10 IPF breathing spontaneously. Haemodynamic blood parameters were measured under the following conditions: 1) room air; 2) during 2 parts per million (ppm) NO 3) whilst O2 alone (1 L.min-1); 4) combined ppm L.min-1). During air mean arterial pressure (Ppa 25 +/- 3 vs 30 4 mmHg)...
