Abstract
For achieving accurate and safe measurements of the force and power exerted on a load during resistance exercise, the Smith machine has been used instead of free weights. However, because some Smith machines possess counterweights, the equation for the calculation of force and power in this system should be different from the one used for free weights. The purpose of this investigation was to calculate force and power using an equation derived from a dynamic equation for a Smith machine with counterweights and to determine the differences in force and power calculated using 2 different equations. One equation was established ignoring the effect of the counterweights (Method 1). The other equation was derived from a dynamic equation for a barbell and counterweight system (Method 2). 9 female collegiate judo athletes performed bench throws using a Smith machine with a counterweight at 6 different loading conditions. Barbell displacement was recorded using a linear position transducer. The force and power were subsequently calculated by Methods 1 and 2. The results showed that the mean and peak power and force in Method 1 were significantly lower relative to those of Method 2 under all loading conditions. These results indicate that the mean and peak power and force during bench throwing using a Smith machine with counterweights would be underestimated when the calculations used to determine these parameters do not account for the effect of counterweights.

Abstract
Allergic rhinitis (AR) and asthma represent global health problems for all age groups. Asthma and rhinitis frequently coexist in the same subjects. Allergic Rhinitis and its Impact on Asthma (ARIA) was initiated during a World Health Organization workshop in 1999 (published in 2001). ARIA has reclassified AR as mild/moderate-severe and intermittent/persistent. This classification closely reflects patients' needs and underlines the close relationship between rhinitis and asthma. Patients, clinicians, and other health care professionals are confronted with various treatment choices for the management of AR. This contributes to considerable variation in clinical practice, and worldwide, patients, clinicians, and other health care professionals are faced with uncertainty about the relative merits and downsides of the various treatment options. In its 2010 Revision, ARIA developed clinical practice guidelines for the management of AR and asthma comorbidities based on the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) system. ARIA is disseminated and implemented in more than 50 countries of the world. Ten years after the publication of the ARIA World Health Organization workshop report, it is important to make a summary of its achievements and identify the still unmet clinical, research, and implementation needs to strengthen the 2011 European Union Priority on allergy and asthma in children.

Abstract
We employed immunohistochemical methods to investigate the overexpression of cyclin D1 protein as well as p53 protein and retinoblastoma protein (pRb) in 57 patients with transitional cell carcinoma (TCC) of the urinary tract, in order to determine their frequency and significance, and also association with the clinicopathological behavior of this tumor. Nuclear immunostaining with cyclin D1 antibody revealed 7 homogeneously stained tumors (12.3%), including 4 heterogeneous pRb expressions, of which only one was also positive for p53. Positive immunostaining with each antibody to p53 or pRb was obtained in 15 (26.3%) and 49 (86%) tumors, respectively. The 49 pRb-positive tumors included 6 homogeneous and 43 heterogeneous nuclear immunostaining patterns. The remaining pRb-negative 8 tumors included 5 cyclin D1-negative tumors. The prevalence of p53 staining was higher in high-grade (P<0.05) and invasive types of tumors (P<0.05) than the other types studied. On the other hand, no significant relationship was found between cyclin D1- or pRb-immunoreactivity and clinicopathological factors. These findings provide evidence for infrequent cyclin D1 protein overexpression in TCC independently associated with p53 protein and/or pRb overexpression.

Abstract
A spectrophotometric method for the determination of trace amounts of manganese with 1-(2-pyridylazo)-2-naphthol (PAN) is described. The method is based on the measurement of absorbance of the manganese-PAN chelate solubilized with a non-ionic surfactant, Triton X-100. No extraction procedure is required in the method proposed. High concentrations of calcium, aluminium and magnesium do not interfere. The presence of up to 10 ppm of lead can be tolerated. Iron, cadmium, zinc, cobalt and nickel can be effectively masked with potassium cyanide. Beer's law is obeyed up to 2 ppm of manganese. The molar absorptivity of the manganese-PAN chelate found was 4.4 x 10(4) l. mole (-1). cm(-1) at 562 nm. The overall stability constant of Mn(PAN)(2) in 0.4% Triton X-100 medium is 10(16.8).

Abstract
Concepts of disease severity, activity, control and responsiveness to treatment are linked but different. Severity refers to the loss of function of the organs induced by the disease process or to the occurrence of severe acute exacerbations. Severity may vary over time and needs regular follow-up. Control is the degree to which therapy goals are currently met. These concepts have evolved over time for asthma in guidelines, task forces or consensus meetings. The aim of this paper is to generalize the approach of the uniform definition of severe asthma presented to WHO for chronic allergic and associated diseases (rhinitis, chronic rhinosinusitis, chronic urticaria and atopic dermatitis) in order to have a uniform definition of severity, control and risk, usable in most situations. It is based on the appropriate diagnosis, availability and accessibility of treatments, treatment responsiveness and associated factors such as comorbidities and risk factors. This uniform definition will allow a better definition of the phenotypes of severe allergic (and related) diseases for clinical practice, research (including epidemiology), public health purposes, education and the discovery of novel therapies.

Abstract
Specific strains of Lactobacillus have been found to be beneficial in treating some types of diarrhea and vaginosis. However, a high mortality rate results from underlying immunosuppressive conditions in patients with Lactobacillus casei bacteremia. Cyclic AMP (cAMP) is a small second messenger molecule that mediates signal transduction. The onset and progression of inflammatory responses are sensitive to changes in steady-state cAMP levels. L. casei cell wall extract (LCWE) develops arteritis in mice through Toll-like receptor-2 signaling. The purpose of this study was to investigate whether intracellular cAMP affects LCWE-induced pathological signaling. LCWE was shown to induce phosphorylation of the nuclear factor κB (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways and cell proliferation in mice fibroblast cells. Theophylline and phosphodiesterase inhibitor increased intracellular cAMP and inhibited LCWE-induced cell proliferation as well as phosphorylation of NF-κB and MAPK. Protein kinase A inhibitor H89 prevented cAMP-induced MAPK inhibition, but not cAMP-induced NF-κB inhibition. An exchange protein activated by cAMP (Epac) agonist inhibited NF-κB activation but not MAPK activation. These results indicate that an increase in intracellular cAMP prevents LCWE induction of pathological signaling pathways dependent on PKA and Epac signaling.

Abstract
OBJECTIVE Protein-energy malnutrition is a common disorder in the elderly. Although serum albumin is commonly used as a nutritional marker, data is lacking on serum albumin levels in the elderly. The purpose of this study was to determine whether serum albumin levels decrease with advancing age and to establish reference value and interval of laboratory data for elderly people (75 years and over). PARTICIPANTS Blood samples from 13821 healthy people, 42064 outpatients, and 15959 inpatients were collected during 2008. Blood from 127 of our nutrition support team (NST) patients was also collected during August 2006 and May 2009, and analyzed. MEASUREMENTS Serum albumin, hemoglobin, total cholesterol levels and lymphocyte count were determined. We analyzed the change in each parameter in accordance with age, compared the data for elderly people with younger people, and established new reference values. Clinical outcomes were examined depending on the improved reference values. RESULTS Albumin was lower in older persons than in younger persons. The estimated reference value and interval were 42 (48-36) g/l in older persons and was much lower in NST patients. Hemoglobin was decreased while cholesterol and lymphocyte count were not changed in older persons: all were markedly decreased in NST patients. Terms of hospital stay were significantly longer and mortality rates were significantly higher in older persons, comparing from above to below using a new reference value of albumin (36 g/l). CONCLUSIONS The serum albumin level decreases with advancing age, but it was maintained to some extent in healthy older people. Serum albumin levels related to the clinical outcome. Hemoglobin and cholesterol levels and lymphocyte count were all lower in NST patients. These measurements may be valuable markers of nutritional status and can help in guiding the need for nutritional support.

Abstract
This pocket guide is the result of a consensus reached between members of the Global Allergy and Asthma European Network (GA(2) LEN) and Allergic Rhinitis and its Impact on Asthma (ARIA). The aim of the current pocket guide is to offer a comprehensive set of recommendations on the use of skin prick tests in allergic rhinitis-conjunctivitis and asthma in daily practice. This pocket guide is meant to give simple answers to the most frequent questions raised by practitioners in Europe, including 'practicing allergists', general practitioners and any other physicians with special interest in the management of allergic diseases. It is not a long or detailed scientific review of the topic. However, the recommendations in this pocket guide were compiled following an in-depth review of existing guidelines and publications, including the 1993 European Academy of Allergy and Clinical Immunology position paper, the 2001 ARIA document and the ARIA update 2008 (prepared in collaboration with GA(2) LEN). The recommendations cover skin test methodology and interpretation, allergen extracts to be used, as well as indications in a variety of settings including paediatrics and developing countries.

Abstract
Originally found in stomach mucosa, ghrelin is a peptide appetite hormone that has been implicated as an immuno-modulatory factor. Ghrelin has also been found in salivary glands and saliva; however, its expression patterns and biological properties in the oral cavity remain unclear. Therefore, we investigated the expression patterns of ghrelin in saliva, gingival crevicular fluid (GCF), and gingival tissue, as well as its in vitro effects on IL-8 production by TNF-α or LPS-stimulated oral epithelial cells. In the clinical samples obtained from 12 healthy volunteers, the concentration of ghrelin in GCF remarkably exceeded that detected in saliva. The expression of ghrelin mRNAs and growth hormone secretagogue (GHS) receptors could be detected in human oral epithelial cells. Immunohistochemical analysis revealed the expression of ghrelin in gingival epithelium, as well as in fibroblasts in the lamina propria. Ghrelin increased intracellular calcium mobilization and cAMP levels in oral epithelial cells, suggesting that ghrelin acts on epithelial cells to induce cell signaling. Furthermore, synthetic ghrelin inhibited the production of IL-8 from TNF-α or LPS-stimulated oral epithelial cells. These results indicate that ghrelin produced in the oral cavity appears to play a regulatory role in innate immune responses to inflammatory infection.

Abstract
Wiskott-Aldrich syndrome (WAS) is a rare X-linked disorder caused by mutations in the WAS gene. Glomerulonephritis is a frequent complication, however, histopathological data from affected patients is scarce because the thrombocytopenia that affects most patients is a contraindication to renal biopsies. We found that WASp-deficient mice develop proliferative glomerulonephritis reminiscent of human IgA nephropathy (IgAN). We examined whether increased aberrant IgA production is associated with the development of glomerulonephritis in WASp-deficient mice. Serum IgA and IgA production by splenic B cells was increased in WASp-deficient mice compared to wild-type (WT) mice. A lectin-binding study revealed a reduced ratio of sialylated and galactosylated IgA in the sera from old WASp-deficient mice. Circulating IgA-containing immune complexes showed significantly higher titers in WASp-deficient mice compared to WT mice. These results indicate that the increased IgA production and aberrant glycosylation of IgA may be critically involved in the pathogenesis of glomerulonephritis in WAS.

Abstract
BACKGROUND Asthma and rhinitis are common co-morbidities everywhere in the world but nation-wide studies assessing rhinitis in asthmatics using questionnaires based on guidelines are not available. OBJECTIVE To assess the prevalence, classification, and severity of rhinitis using the Allergic Rhinitis and its Impact on Asthma (ARIA) criteria in Japanese patients with diagnosed and treated asthma. METHODS The study was performed from March to August 2009. Patients in physicians' waiting rooms, or physicians themselves, filled out questionnaires on rhinitis and asthma based on ARIA and Global Initiative for Asthma (GINA) diagnostic guides. The patients answered questions on the severity of the diseases and a Visual Analog Scale. Their physicians made the diagnosis of rhinitis. RESULTS In this study, 1910 physicians enrolled 29,518 asthmatics; 15,051 (51.0%) questionnaires were administered by physician, and 26,680 (90.4%) patients were evaluable. Self- and physician-administered questionnaires gave similar results. Rhinitis was diagnosed in 68.5% of patients with self-administered questionnaires and 66.2% with physician-administered questionnaires. In this study, 994 (7.6%) patients with self-administered and 561 (5.2%) patients with physician-administered questionnaires indicated rhinitis symptoms on the questionnaires without a physician's diagnosis of rhinitis. Most patients with the physician's diagnosis of rhinitis had moderate/severe rhinitis. Asthma control was significantly impaired in patients with a physician's diagnosis of rhinitis for all GINA clinical criteria except exacerbations. There were significantly more patients with uncontrolled asthma as defined by GINA in those with a physician's diagnosis of rhinitis (25.4% and 29.7%) by comparison with those without rhinitis (18.0% and 22.8%). CONCLUSION Rhinitis is common in asthma and impairs asthma control.

Abstract
Pulmonary arterial hypertension (PAH) when associated with systemic sclerosis (SSc) (SSc-PAH) is one of the leading causes of mortality and is found in 10-15% of adult patients with SSc. The ET receptor antagonist bosentan has been shown to be effective in the treatment of adult patients with SSc-PAH. Furthermore, it has been shown that bosentan ameliorates decreased skin perfusion and digital ulceration secondary to SSc. However, the effectiveness and safety of bosentan for treatment of juvenile SSc still remains unclear. We describe a case of juvenile SSc-PAH successfully treated with bosentan. The present case shows that bosentan ameliorated PAH and peripheral circulation as evaluated by cold stress thermography. No bosentan-related adverse events such as liver dysfunction were observed. Prospective randomized trials are required to validate the effectiveness of bosentan for patients with juvenile SSc; however, bosentan might be useful for the management of patients with juvenile SSc.

Abstract
BACKGROUND Balloon angioplasty has recently been adopted as an acceptable form of treatment for stenotic vessel lesions of congenital heart diseases. However, precise mechanisms of restenosis and thrombosis, which are the most common complications after these procedures, are unknown. METHODS We examined the effects of antithrombin III (ATIII) on inflammation, thrombus formation, and remodeling of vascular wall after guidewire-induced injury in the femoral artery of mice. ATIII or saline was administered as a bolus intravenous infusion before injury. RESULTS Seventy-two hours after injury, approximately half of the saline-treated vessels showed macroscopic thrombus formation. In contrast, no thrombi were seen in the arteries pretreated with ATIII. Significantly higher levels of inflammation were induced in the injured vessels than in the sham-operated controls, as determined by CD11b-positive cell density in the adventitial area. ATIII treatment resulted in marked reduction of inflammatory cell infiltration. Twenty-eight days after injury, similar levels of neointimal proliferation were found in the injured arteries in both groups. CONCLUSIONS Our results suggested that a high dose of ATIII may influence the sequelae of arterial injury by reducing mural thrombus formation and limiting the inflammatory reaction of the vessel wall without altering the process of vascular remodeling.

Abstract
OBJECTIVE We assessed out-of-hospital cardiac arrests (OHCAs) for various pediatric age groups. METHODS 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 years), older children (5-12 years), and adolescents (13-17 years). The primary outcome measure was 1-month survival with favorable neurologic outcome. RESULTS Of 950 pediatric OHCAs, resuscitations were attempted for 875 patients (92%; 347 infants, 203 younger children, 135 older children, and 190 adolescents). The overall incidence of nontraumatic pediatric OHCAs was 7.3 cases per 100 000 person-years, compared with 64.7 cases per 100 000 person-years for adults and 65.5 cases per 100 000 person-years for infants. Most infant OHCAs occurred in homes (93%) and were not witnessed (90%). Adolescent OHCAs often occurred outside the home (45%), were witnessed by bystanders (37%), and had shockable rhythms (18%). One-month survival was more common after nontraumatic pediatric OHCAs than adult OHCAs (8% [56 of 740 patients] vs 5% [1677 of 33 091 patients]; adjusted odds ratio: 2.26 [95% confidence interval: 1.63-3.13]). One-month survival with favorable neurologic outcome was more common among children than adults (3% [21 of 740 patients] vs 2% [648 of 33 091 patients]; adjusted odds ratio: 2.46 [95% confidence interval: 1.45-4.18]). Rates of 1-month survival with favorable neurologic outcome were 1% for infants, 2% for younger children, 2% for older children, and 11% for adolescents. CONCLUSION Survival and favorable neurologic outcome at 1 month were more common after pediatric OHCAs than adult OHCAs.
