In the majority of cervical cancers, DNAs high-risk mucosotpropic human papillomaviruses (HPVs), such as type 16, are maintained so to express two viral proteins, E6 and E7, suggesting an essential importance carcinogenesis. The HPV proteins known inactivate p53 tumor suppressor protein but appear have additional, molecularly unknown function(s). this study, we demonstrate that these can bind second PDZ domain homologue Drosophila discs large (hDLG) through their C-terminal XS/TXV/L (where X...

The internal conductance for CO2 diffusion (gi) and assimilation rate were measured the related anatomical characteristics investigated in transgenic rice leaves that overexpressed barley aquaporin HvPIP2;1. This study was performed to test hypothesis facilitates within leaves. gi value estimated intact by concurrent measurements of gas exchange carbon isotope ratio. plants expressed highest levels Aq-anti-HvPIP2;1 showed a 40% increase as compared wild-type plants. accompanied 14% 27%...

Background— Previous animal and clinical studies suggest that bystander-initiated cardiac-only resuscitation may be superior to conventional cardiopulmonary (CPR) for out-of-hospital cardiac arrests. Our hypothesis was both bystander CPR would improve outcomes from arrests of ≤15 minutes’ duration, whereas the addition rescue breathing lasting >15 minutes. Methods Results— We carried out a prospective, population-based, observational study involving consecutive patients with emergency...

Background— The impact of ongoing efforts to improve the “chain survival” for out-of-hospital cardiac arrest (OHCA) is unclear. objective this study was evaluate incremental effect changes in prehospital emergency care on survival after OHCA. Methods and Results— This prospective, population-based observational involved consecutive patients with OHCA from May 1998 through December 2006. primary outcome measure 1-month favorable neurological outcome. Multiple logistic regression analysis used...

We have described clinical features of 53 cases with pustulotic arthro-osteitis. Anterior chest wall symptoms such as intersterno-costoclavicular or manubriosternal lesions were observed in all cases. Spondylitis spondylodiscitis was found 18 Sacroiliitis resembling ankylosing spondylitis seen 7 Peripheral inflammatory arthritis 14 cases, which nonerosive, oligoarthritis type, and cured within 1 to 2 months, leaving no residue. HLA B27 never found, RAW factor negative. Histological...

We engineered a salt‐sensitive rice cultivar ( Oryza sativa cv. Kinuhikari ) to express vacuolar‐type Na + /H antiporter gene from halophytic plant, Atriplex gmelini AgNHX1 ). The activity of the in transgenic plants was eight‐fold higher than that wild‐type plants. Salt tolerance assays followed by non‐stress treatments showed overexpressing could survive under conditions 300 mM NaCl for 3 days while not. These results indicate overexpression significantly improves their salt tolerance.

We assessed out-of-hospital cardiac arrests (OHCAs) for various pediatric age groups.This prospective, population-based, observational study included all emergency medical service-treated OHCAs in Osaka, Japan, between 1999 and 2006 (excluding 2004). Patients were grouped as adults (>17 years), infants (<1 year), younger children (1-4 older (5-12 adolescents (13-17 years). The primary outcome measure was 1-month survival with favorable neurologic outcome.Of 950 OHCAs, resuscitations...

The strategy to place public-access automated external defibrillators (AEDs) has not yet been established in real settings.This, prospective, population-based observational study Osaka, Japan, included consecutive out-of-hospital cardiac arrest (OHCA) patients with resuscitation attempts during 7 years, from January 2005 through December 2011. trends the proportion of AED use and 1-month survival neurologically favorable outcome were evaluated by location. Factors associated (defined as...

Barley HvPIP2;1 is a plasma membrane aquaporin and its expression was down-regulated after salt stress in barley [Katsuhara et al. (2002)Plant Cell Physiol. 43: 885]. We produced analyzed transgenic rice plants over-expressing the present study. Over-expression of increased (1) radial hydraulic conductivity roots (Lpr) to 140%, (2) mass ratio shoot root up 150%. In these under 100 mM NaCl, growth reduction greater than non-transgenic plants. A decrease water content (from 79% 61%) or (both...

Background: The effectiveness of epinephrine administration for cardiac arrests has been shown in animal models, but the clinical effect is still controversial. Methods and Results: A prospective, population-based, observational study Osaka involved consecutive out-of-hospital arrest (OHCA) patients from January 2007 through December 2009. We evaluated outcomes among adult non-traumatic bystander-witnessed OHCA whom local protocol directed emergency medical service personnel to administer...

Abstract Introduction Both supraglottic airway devices (SGA) and endotracheal intubation (ETI) have been used by emergency life-saving technicians (ELST) in Japan to treat out-of-hospital cardiac arrests (OHCAs). Despite traditional emphasis on management during arrest, its impact survival from OHCA time dependent effectiveness remains unclear. Methods All adults with witnessed, non-traumatic OHCA, 1 January 2005 31 December 2008, treated the medical services (EMS) an advanced Osaka, were...
