Off the shelf scaffolds for replacing ultra-small diameter vascular grafts are valuable for reconstruction of diseased or damaged vessels. The limitations for such grafts include optimal handling with ready availability of varied lengths of grafts, graft patency with the ability to replace the function of active cellular mechanisms and adequate mechanical properties to maintain physicochemical function. We used a well-established, solvent casting method for potential tissue replacement scaffold fabrication with incorporated bioactive molecules, which we have previously explored to confer haemocompatibility...

Proteins are the major constituents of muscle and are key molecules regulating the metabolic changes during conversion of muscle to meat. Brazil is one of the largest exporters of beef and most Brazilian cattle are composed by zebu (Nellore) genotype. Bos indicus beef is generally leaner and tougher than Bos taurus such as Angus. The aim of this study was to compare the muscle proteomic and phosphoproteomic profile of Angus and Nellore. Seven animals of each breed previously subjected the same growth management were confined for 84 days...

BACKGROUND: Herpes zoster (HZ) has a significant negative effect on the productive work life of individuals, and has been shown to be responsible for cases of absenteeism, presenteeism and decreased work effectiveness. The aim of this study was to evaluate health utility scores and associated predictors in an actively employed population of Herpes Zoster (HZ) patients with and without work time loss (WTL). METHODS: This was a pooled analysis of the prospective, observational MASTER cohort studies, conducted in 8 countries across North America, Latin America and Asia...

BACKGROUND: Aspirin is a safe and effective prophylaxis for the prevention of venous thromboembolism following total joint arthroplasty. The optimal dose of aspirin prophylaxis is unknown. Our hypothesis was that lower-dose aspirin is as effective as higher-dose aspirin for the prevention of venous thromboembolism and is associated with fewer gastrointestinal side effects. METHODS: In a prospective, crossover study, we analyzed 4,651 primary total joint arthroplasty cases performed from July 2013 to June 2015...

BACKGROUND: Sublingual immunotherapy has been proven as a well-tolerated and effective treatment for allergic rhinitis. Within this type of treatment, GRAZAX(®) is the most documented product in terms of safety and efficacy. The objective of this study was to identify the patients' expectations and level of treatment satisfaction, as well as the clinical management of patients with moderate/severe allergic rhinoconjunctivitis treated with GRAZAX(®). METHODS: This was a non-interventional, observational, multi-centre, open-label study involving a total of 131 adult patients aged 18-66 years with confirmed diagnosis of grass-allergy and initiated treatment with GRAZAX(®) between June 2010 and April 2011...

Smallholder agricultural systems, strongly dependent on water resources and investments in shared infrastructure, make a significant contribution to food security in developing countries. These communities are being increasingly integrated into the global economy and are exposed to new global climate-related risks that may affect their willingness to cooperate in community-level collective action problems. We performed field experiments on public goods with private and collective risks in 118 small-scale rice-producing communities in four countries...

Recently, the involvement of various authors coming from the social sciences and the arts has reinforced the humanistic component of bioethics. Their contributions vary from very theoretical perspectives to rather practical ones. In this paper, Martha Nussbaum's books, The Fragility of Goodness (1986), Love's Knowledge (1990), Cultivating Humanity (1997) and Creating Capabilities (2011) are analysed from the vantage point of narrative bioethics. It is argued that Nussbaum's notions of 'Narrative', 'Imagination' and 'Cultivation' open up the possibility of developing an action-oriented form of narrative bioethics, that is, a bioethics committed to social action and justice...

BACKGROUND: Joubert syndrome is a clinically and genetically heterogeneous ciliopathy. Neuroimaging findings have not been systematically evaluated in a large cohort of patients with Joubert syndrome in correlation with molecular genetic cause and cognitive function. METHODS: Brain MRI of 110 patients with Joubert syndrome was included in this study. A comprehensive evaluation of brain MRI studies for infratentorial and supratentorial morphological abnormalities was performed...

Epilepsy is characterized by spontaneous recurrent seizures and temporal lobe epilepsy (TLE) is the most common serious neurological example of acquired and frequent epilepsy. Oxidative stress is recognized as playing a contributing role in several neurological disorders, and most recently have been implicated in acquired epilepsies. The MTs occur in several brain regions and may serve as neuroprotective proteins against reactive oxygen species causing oxidative damage and stress. The main aim of this work was to describe the immunohistochemical localization of MT in the specimens derived from the patients affected by TLE...

The large multimeric glycoprotein von Willebrand Factor (VWF) plays a pivotal adhesive role during primary hemostasis. VWF is cleaved by the protease ADAMTS13 as a down-regulatory mechanism to prevent excessive VWF-mediated platelet aggregation. For each VWF monomer, the ADAMTS13 cleavage site is located deeply buried inside the VWF A2 domain. External forces in vivo or denaturants in vitro trigger the unfolding of this domain, thereby leaving the cleavage site solvent-exposed and ready for cleavage. Mutations in the VWF A2 domain, facilitating the cleavage process, cause a distinct form of von Willebrand disease (VWD), VWD type 2A...

BACKGROUND: Polyphosphate (polyP) is a linear biopolymer found in all living cells. In bacteria, mutants lacking polyphosphate kinase 1 (PPK1), the enzyme responsible for synthesis of most polyP, have many structural and functional defects. However, little is known about the causes of these pleiotropic alterations. The link between ppk1 deletion and those numerous phenotypes observed can be the result of complex molecular interactions that can be elucidated via a systems biology approach...

Predation risk is allegedly reduced in Batesian and Müllerian mimics, because their coloration resembles the conspicuous coloration of unpalatable prey. The efficacy of mimicry is thought to be affected by variation in the unpalatability of prey, the conspicuousness of the signals, and the visual system of predators that see them. Many frog species exhibit small colorful patches contrasting against an otherwise dark body. By measuring toxicity and color reflectance in a geographically variable frog species and the syntopic toxic species, we tested whether unpalatability was correlated with between-species color resemblance and whether resemblance was highest for the most conspicuous components of coloration pattern...

BACKGROUND: Brazil is a developing country struggling to reduce its extreme social inequality, which is reflected on shortage of health-care infrastructure, mainly to the low-income class, which depends exclusively on the public health system. In Brazil, less than 1% of stroke patients have access to intravenous thrombolysis in a stroke unit, and constraints to the development of mechanical thrombectomy in the public health system increase the social burden of stroke. OBJECTIVE: Report the feasibility of mechanical thrombectomy as part of routine stroke care in a Brazilian public university hospital...
