Maximal respiratory pressure reference values for Navajo children ages 6-14

Background Since anthropometric variables are critical to the creation of pulmonary nomograms for FVC, FEV1, and other volumes and capacities, it is logical that anthropometric variables also influence the values of the maximal respiratory pressures (MRPs). Since nomograms are race-specific, it is important that tribe-specific tables of normal maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) be developed. To date normal tables for MRPs do not exist for Navajo children. Objective Therefore the purpose of this study was to derive MRP normative reference values for Navajo children in the age range of 6–14 years. Methods—Participants and Measurements A cross-sectional st…

Physical frailty in liver transplantation.

In patients with cirrhosis, frailty represents a status of global physical dysfunction associated with a multiplicity of factors, including muscle wasting, undernutrition and malnutrition, and functional impairment. This condition is particularly prevalent among those with advanced cirrhosis, such as liver transplant (LT) candidates. Studies in this vulnerable population have demonstrated that its presence is independently predictive of adverse outcomes both pre- and post-transplantation, and thus that its incorporation into clinical practice could result in improved clinical decision-making, particularly regarding the identification of candidates for physical and nutritional interventions.…

Using the Updated EWGSOP2 Definition in Diagnosing Sarcopenia in Spanish Older Adults : Clinical Approach

Recently the European Working Group on Sarcopenia in Older People (EWGSOP2) has updated diagnostic criteria for sarcopenia, which consist of one or more measures of muscle strength, muscle mass, and physical performance, plus an initial screening test called SARC-F. The main objective was to compare the number of cases of sarcopenia, using the different measurements and screening options. A cross-sectional study was conducted on Spanish older adults (n = 272, 72% women). Combining the different measures proposed by the steps described in the EWGSOP2 algorithm, 12 options were obtained (A–L). These options were studied in each of the three models: (1) using SARC-F as initial screening

Nueva evidencia sobre la Statistical Anxiety Scale (SAS)

Title: New evidence on the Statistical Anxiety Scale (SAS). Abstract: As anxiety is negatively related to academic performance, and it is broadly known the existence of both anxiety towards statistics and nega- tive statistics results, statistical anxiety may play a role of mediating negative outcomes in this subject. In this context, the Statistical Anxiety Scale (Vigil- Colet, Lorenzo-Seva, & Condon, 2008) aims to be a useful tool in the comparison of the predictive power of specific and general measures of statistics performance. In order to achieve this goal, the scale is based on three dimensions of anxiety, referred to three specific issues: regarding the exam, when asking for help or…

Structural mannoproteins released by β-elimination fromCandida albicanscell walls

Abstract Mild alkaline solutions (β-elimination), after removing the non-covalently bonded wall materials by hot SDS, released 13% and 26% of remaining wall proteins from mycelial and yeast cells of Candida albicans, respectively. When the β-elimination was carried out after digestion of the walls with chitinase, four-fold more proteinaceous materials were released from mycelium and a similar amount in yeast walls. The solubilized materials were shown to be highly polydisperse, and endo-glycosidase H reduced their polydispersity and molecular masses, revealing different electrophoretic patterns in yeast and mycelial cell walls. The solubilized mycelial proteins carried N-glycosidic sugar ch…

Abstract Iranzo, M., Marcilla, A., Elorza, M. V., Mormeneo, S., and Sentandreu, R. 1994. Preparation of anti-protein and anti-mannan antisera against fungal cell wall by affinity chromatography. Experimental Mycology 18, 159-167. A novel and easy chromatographic method has been developed for the isolation of anti-protein and anti-mannan antisera from a population of polyclonal antibodies obtained against Candida albicans and Yarrowia lipolytica cell wall mannoproteins. The technique is based on the immobilization of mannan (to be used as immunoadsorbent) by Affi-Prep H z resin after the oxidation of neighboring hydroxyl groups of the polysaccharide with sodium periodate. For Y. lipolytica p…

Study of supramolecular structures released from the cell wall of Candida albicans by ethylenediamine treatment

Candida albicans cell wall components were analyzed by ethylenediamine (EDA) treatment. Based on their different solubility properties, the cell wall components produced three fractions (A, B, and C). Fractions B (EDA-soluble, water-insoluble) and C (EDA-insoluble) contained glucan, chitin, and protein in different proportions. After zymolyase (mainly a beta-glucanase complex) or chitinase treatment of fractions B and C, more polysaccharides and proteins were solubilized by a second EDA treatment, suggesting that the solubility of the polymers in EDA depends on the degree of polymer interactions. Western blot analysis using two monoclonal antibodies (1B12 and 4C12) revealed electrophoretic …

Frailty and Sarcopenia in Acute‐on‐Chronic Liver Failure

In patients with cirrhosis, sarcopenia is a critical reduction in skeletal muscle mass and frailty represents a status of global physical dysfunction caused by under nutrition, muscle wasting, and functional impairment. Both are prevalent conditions in liver transplant candidates and have shown to be independent predictors of adverse outcome. Evidence supports their incorporation into clinical practice both as a prognostic factor guiding clinical decision making and as a tool to identify candidates for physical and nutritional interventions. The wide heterogeneity of instruments used for sarcopenia and frailty measurement, the absence of a single suitable instrument for sarcopenia and frail…

Cardiopulmonary rehabilitation improves respiratory muscle function and functional capacity in children with congenital heart disease : a prospective cohort study

Critical surgical and medical advances have shifted the focus of congenital heart disease (CHD) patients from survival to achievement of a greater health-related quality of life (HRQoL). HRQoL is influenced, amongst other factors, by aerobic capacity and respiratory muscle strength, both of which are reduced in CHD patients. This study evaluates the influence of a cardiopulmonary rehabilitation program (CPRP) on respiratory muscle strength and functional capacity. Fifteen CHD patients, ages 12 to 16, with reduced aerobic capacity in cardiopulmonary exercise testing (CPET) were enrolled in a CPRP involving strength and aerobic training for three months. Measurements for comparison were obtai…

Maximal Respiratory Pressure Reference Values For Navajo Children Ages 6 To 14 Years

Comparison Of Patient Satisfaction And Compliance With Two Respiratory Muscle Training Programs In The Frail Elderly

Possible Roles of Mannoproteins in the Construction of Candida Albicans Cell Wall

The shape of Candida albicans cells depends on their cell walls and some of their mannoproteins may act as modulators of the final molecular architecture. If that were the case, the wall mannoproteins might form part of what could be called a “morphogenetic code”.

Involvement of transglutaminase in the formation of covalent cross-links in the cell wall of Candida albicans.

Activity of the enzyme glutaminyl-peptide--glutamylyl-transferase (EC 2.3.2.13; transglutaminase), which forms the interpeptidic cross-link N epsilon-(gamma-glutamic)-lysine, was demonstrated in cell-free extracts obtained from both the yeast like and mycelial forms of Candida albicans. Higher levels of enzymatic activity were observed in the cell wall fraction, whereas the cytosol contained only trace amounts of activity. Cystamine, a highly specific inhibitor of the enzyme, was used to analyze a possible role of transglutaminase in the organization of the cell wall structure of the fungus. Cystamine delayed protoplast regeneration and inhibited the yeast-to-mycelium transition and the inc…

Reaggregation and binding of cell wall proteins from Candida albicans to structural polysaccharides

Urea or hot sodium dodecyl sulphate extracted a significant amount of the same proteins from the matrix of the cell wall of the yeast form and mycelial cells of Candida albicans. Gel filtration analysis of the urea-extracted proteins revealed that they occurred in the form of large complexes which were unaffected by up to 8 M urea. Among them, proteins en route to becoming covalently associated within the wall scaffold were identified by their reaction with specific antibodies. When urea was removed by dialysis, some of these proteins specifically reassociated into large aggregates which bound strongly with ConA, whereas others remained soluble in smaller associated products. The ability of…

Characteristics of rice straw and sewage sludge as composting materials in Valencia (Spain).

This work supports the idea that composting can be useful for minimizing the rice straw and sewage sludge environmental impact. Several physical, chemical and microbiological properties of these raw materials were analyzed. The characteristics of the rice straw were complementary to those of the sewage sludge for the application of composting. The C/N ratios suitable for a rapid increased in microbial activity were the lowest (17-24). A temperature of 62 degrees C during 48 h removed pathogenic microorganisms from rice straw and sewage sludge mixture. The results obtained in the present work suggested that these materials could be use in the composting process.

The use of trypsin to solubilize wall proteins from Candida albicans led to the identification of chitinase 2 as an enzyme covalently linked to the yeast wall structure

The use of trypsin to break proteins covalently linked to the yeast walls of Candida albicans released approx. 50% of the proteins, but also glucose and N-acetylglucosamine. Analysis by affinity chromatography indicated that glucose and/or N-acetylglucosamine formed part of the same supramolecular complexes with mannoproteins. These complexes would represent a new type of cell wall structuration in which beta-1,6 glucan and chitin are linked to proteins. An internal peptide from a 50-kDa protein released by trypsin was sequenced, showing 100% identity with chitinase 2 protein and 92% with chitinase 3. The electrophoretic mobility of the chitinase 2 protein was changed by treatment with Endo…

The Candida albicans ENO1 gene encodes a transglutaminase involved in growth, cell division, morphogenesis, and osmotic protection

Candida albicans is an opportunistic fungus that is part of the normal microflora commonly found in the human digestive tract and the normal mucosa or skin of healthy individuals. However, in immunocompromised individuals, it becomes a serious health concern and a threat to their lives and is ranked as the leading fungal infection in humans worldwide. As existing treatments for this infection are non-specific or under threat of developing resistance, there is a dire necessity to find new targets for designing specific drugs to defeat this fungus. Some authors reported the presence of the transglutaminase activity in Candida and Saccharomyces, but its identity remains unknown. We report here…
