Main specifications of CFD codes for WUIVIEW activities

CFD simulations will be the core activity of the WUVIEW performance based fire safety analysis. The purpose of this document is to provide WUIVIEW partners with a general overview of the CFD codes to be used in the Action. The general simulation framework is described, particularly highlighting data inputs and scenario description requirements, to be developed in subsequent WUIVIEW WPs. This TN provides the technical foundations and main specifications of the databases to be designed within the WUIVIEW working program (ongoing action by UPC).Postprint (updated version

Coexistence of Wolbachia with Buchnera aphidicola and a secondary symbiont in the aphid Cinara cedri.

Intracellular symbiosis is very common in the insect world. For the aphid Cinara cedri, we have identified by electron microscopy three symbiotic bacteria that can be characterized by their different sizes, morphologies, and electrodensities. PCR amplification and sequencing of the 16S ribosomal DNA (rDNA) genes showed that, in addition to harboring Buchnera aphidicola, the primary endosymbiont of aphids, C. cedri harbors a secondary symbiont (S symbiont) that was previously found to be associated with aphids (PASS, or R type) and an alpha-proteobacterium that belongs to the Wolbachia genus. Using in situ hybridization with specific bacterial probes designed for symbiont 16S rDNA sequences, we have shown that Wolbachia was represented by only a few minute bacteria surrounding the S symbionts. Moreover, the observed B. aphidicola and the S symbionts had similar sizes and were housed in separate specific bacterial cells, the bacteriocytes. Interestingly, in contrast to the case for all aphids examined thus far, the S symbionts were shown to occupy a similarly sized or even larger bacteriocyte space than B. aphidicola. These findings, along with the facts that C. cedri harbors the B. aphidicola strain with the smallest bacterial genome and that the S symbionts infect all Cinara spp. analyzed so far, suggest the possibility of bacterial replacement in these species

Bisphosphonate-associated osteonecrosis of the jaw : a proposal for conservative treatment

The use of bisphosphonates (BPs) has proven effective in the treatment of bone-related diseases, despite the potential risk of developing osteonecrosis of the jaw (ONJ). So far, results for the treatment of ONJ have not been satisfactory. In our study, we have treated two patients diagnosed with ONJ. In addition to local treatments a hydrogel was applied, with promising results. The fistulae disappeared 2-3 weeks into the treatment. After a six-month follow-up period there has been no sign of recurrence. The extent of maxillary bone exposure has diminished notably, although not entirely disappeared. In all cases, the patients exhibit no other symptoms (they suffer from no pain or swelling or functional impotence). For this reason we believe this protocol might be useful in the case of patients who suffer from pain and fistulation secondary to BP-associated ONJ to improve the state of their lesions until definitive treatment can be undertaken. Although these findings are not conclusive, given that we are reporting data on two patients only, we believe that this might be an alternative treatment in refractory cases where other therapies are counter-indicated. A controlled randomized and prospective study would be required to confirm our findings

Cervical artrosis: effectiveness of a conventional physiotherapic treatment

El objetivo de este estudio consiste en valorar la efectividad de un tratamiento de fisioterapia convencional para la cervicoartrosis (microondas, tracción cervical, movilización activa, masaje e higiene postural). Para su realización, se han seleccionado 32 pacientes (26 mujeres y 6 hombres) diagnosticados de cervicoartrosis. Se han valorado factores como el dolor y el balance articular. Tras analizar los resultados, concluimos que el tratamiento planteado es efectivo en la patología de artrosis cervical.Terapia y Rehabilitació

Soybean Seed Lectin Prevents the Accumulation of S-Adenosyl Methionine Synthetase and the S1 30S Ribosomal Protein in <i>Bradyrhizobium japonicum</i> Under C and N Starvation

Soybean lectin (SBL) participates in the recognition between Bradyrhizobium japonicum and soybean although its role remains unknown. To search for changes in the proteome in response to SBL, B. japonicum USDA 110 was incubated for 12 h in a C- and N-free medium with or without SBL (10 μg ml ⁻¹), and the soluble protein profiles were compared. Two polypeptides, S-adenosyl-methionine synthetase (MetK) and the 30S ribosomal protein S1 (RpsA), were found only in the fractions from rhizobia incubated without SBL. Transcript levels of metK and rpsA were not correlated with polypeptide levels, indicating that there was regulation at translation. In support of this proposal, the 5′ translation initiation-region of rpsA mRNA contained folding elements as those involved in regulation of its translation in other species. Disappearance of MetK and RpsA from the soluble protein fractions of SBL-treated rhizobia suggests that SBL might have attenuated the nutritional stress response of B. japonicum.Instituto de Biotecnología y Biología Molecula

Familial pulmonary fibrosis is the strongest risk factor for idiopathic pulmonary fibrosis

SummaryIdiopathic pulmonary fibrosis (IPF) is a lethal lung disorder of unknown etiology. The disease is likely the result of complex interactions between genetic and environmental factors. Evidence suggests that certain environmental factors, such as cigarette smoking and metal dust exposures, or comorbidities like gastroesophageal reflux, and type 2 diabetes mellitus (DM2) may increase risk to develop IPF. Substantial uncertainty remains, however, regarding these and other putative risk factors for IPF. In this study we performed a case–control analysis including 100 patients with IPF and 263 controls matched for age sex and place of residence. We used a structured questionnaire to identify potential risk factors for IPF, including environmental and occupational exposures as well as the relevance of family history of pulmonary fibrosis. The multivariate analysis revealed that family history of pulmonary fibrosis [OR = 6.1, CI95% 2.3–15.9; p < 0.0001] was strongly associated with increased risk of IPF. Actually, 20% of the cases reported a parent or sibling with pulmonary fibrosis. Gastroesophageal reflux [OR = 2.9, CI: 1.3–6.6; p = 0.007], former cigarette smoking [OR = 2.5, CI: 1.4–4.6, p = 0.003], and past or current occupational exposure to dusts, smokes, gases or chemicals [OR = 2.8, CI: 1.5–5.5; p = 0.002] were also associated with the disease. Despite being a significant risk factor on univariate analysis DM2 was not significant in multivariate analysis. These findings indicate that family history of pulmonary fibrosis is a strong risk factor for IPF. Also, we confirmed that occupational exposures, gastroesophageal reflux and former smoking increase the risk for this disease

The efficacy of acupuncture and decompression splints in the treatment of temporomandibular joint pain-dysfunction syndrome

Objectives: The goal of the present study was to evaluate the results of applying acupuncture or occlusal decompression splints in the treatment of patients diagnosed with the temporomandibular joint pain-dysfunction syndrome. Design of the study: We conducted a randomized clinical trial including 20 patients to whom the mentioned treatments were applied. Results were evaluated through an analogue pain scale, measurements of mouth opening and jaw lateral deviation in millimetres, and assessment of sensitivity to pressure on different points: preauricular, masseter muscle, temporal muscle and trapezius. Parameters were evaluated before and 30 days after the treatment. For standardized pressure, we used a pressure algometer. Results: Patients treated with decompression splints showed reductions in subjective pain and pain upon pressure on temporal, masseter and trapezius muscles, as well as increased mouth opening after the treatment. Patients treated with acupuncture showed pain reduction in the short term and improvements in all of the evaluated para- meters (stronger pressure was required to produce pain; mouth opening was improved). Conclusion: Acupuncture was an effective complement and/or an acceptable alternative to decompression splints in the treatment of myofascial pain and temporomandibular joint pain-dysfunction syndrome
