The new Argentine Civil and Commercial Code includes the prevention principle. The precautionary Principle is regulated by the Environmental Protection Act.A significant number of cases have reached the Supreme Court of the Nation. This Court, in general, estimates that the decisions concerning the precautionary principle have definitive nature, i.e., are not merely provisional. Usually, the situation is caused by the State itself, which fails to control. The different decisions show a Judiciary worried about protecting the environment...

Novel approaches for classification, including molecular features, are needed to direct therapy for men with low-grade prostate cancer (PCa), especially men on active surveillance. Risk alleles identified from genome-wide association studies (GWAS) could improve prognostication. Those risk alleles that coincided with genes and somatic copy number aberrations associated with progression of PCa were selected as the most relevant for prognostication. In a systematic literature review, a total of 698 studies were collated...

Pseudomonas aeruginosa is an opportunistic pathogen implicated in nosocomial infections for which no vaccines have been approved. Larrea divaricata Cav. (Jarilla) is a widely spread plant in America and it is used in folk medicine to treat several pathologies. It has also been shown that antibodies elicited against Jarilla proteins of crude extract (JPCE) cross-react with proteins from gram-negative bacteria. In this study we aim to assess the contribution of anti-JPCE antibodies in the opsonophagocytosis of P...

The capsid of P22 bacteriophage undergoes a series of structural transitions during maturation that guide it from spherical to icosahedral morphology. The transitions include the release of scaffold proteins and capsid expansion. Although P22 maturation has been investigated for decades, a unified model that incorporates thermodynamic and biophysical analyses is not available. A general and specific model of icosahedral capsid maturation are of significant interest to theoreticians searching for fundamental principles as well as virologists and material scientists seeking to alter maturation to their advantage...

Patients undergoing allogenic hematopoietic stem cell transplantation (allo-HSCT) are at a very high risk of hepatitis B virus reactivation (HBVr). Lamivudine is commonly used as prophylaxis against HBVr in high risk patients undergoing allo-HSCT. Unfortunately, its efficacy is diminishing due to the development of HBV mutant drug resistant strains. With the availability of newer antiviral agents like Entecavir, Telbivudine, Adefovir and Tenofovir, it is important to assess their role in HBVr prophylaxis. A comprehensive search of seven databases was performed to evaluate efficacy of antiviral prophylaxis against HBVr in allo-HSCT patients (PubMed/Medline, Embase, Scopus, Cochrane Library, Web of Science, CINAHL, and ClinicalTrials...

BACKGROUND: In medical practice, long term interventions are common and they require timely planning of the involved processes. Unfortunately, evidence-based statements about time are hard to find in Clinical Practice Guidelines (CPGs) and in other sources of medical knowledge. At the same time, health care centers use medical records and information systems to register data about clinical processes and patients, including time information about the encounters, prescriptions, and other clinical actions...

High fat diet (HFD) exposure is associated with various pathological dysfunctions, including haematological disorders and oxidative stress. The in vitro analysis of AECG revealed the presence of important levels of polyphenols and flavonoids, and denoted antioxidant capacities confirmed by nitric oxide radical (NO• ), reducing the power and HPLC chemical components' determinations. The animals exposed to HFD revealed a severe damage in the blood cells structure and haematological parameters accompanied with a significant decrease in serum Mg2+ and Ca2+ ATPase activities...

Goodpasture antigen-binding protein (GPBP) is an exportable1 Ser/Thr kinase that induces collagen IV expansion and has been associated with chemoresistance following epithelial-to-mesenchymal transition (EMT). Here we demonstrate that cancer EMT phenotypes secrete GPBP (mesenchymal GPBP) which displays a predominant multimeric oligomerization and directs the formation of previously unrecognized mesh collagen IV networks (mesenchymal collagen IV). Yeast two-hybrid (YTH) system was used to identify a260 SHCIE264 motif critical for multimeric GPBP assembly which then facilitated design of a series of potential peptidomimetics...

We aim to investigate some of the pathogenetic mediators of the human echinococcosis and to obtain updated epidemiological findings on cases of echinococcosis in Calabria, Southern Italy. Echinococcosis diagnosis was based on imaging, serological investigations, and molecular assay. Indeed, real-time PCR indicated the presence of G2/G3 genotypes of Echinococcus granulosus complex. Regarding pathogenesis, a relevant novel tool of immune depression should be deemed the reduced level of serum MCP-1. Also, we found a previously unreported VEGF, possibly associated with neovascularization requested by the parasite cyst metabolism...

Endoscopic resection (ER) has become the standard therapy for superficial Barrett's carcinoma (BC) in Japan and other countries. Patients undergoing ER sometimes require additional treatment because of recurrence of lymph node metastasis (LNM). We attempted to clarify the histopathologic risk factors for LNM, and the difference between these risk factors for Japanese patients and the conventional risk factors documented for Western patients. This multi-center study included 12 leading institutions belonging to the Japan Research Society for Early Esophageal Cancer and Chromoendoscopy, and was based on a questionnaire designed to gather data on the features of superficial BC cases, except for high-grade intraepithelial neoplasia, treated at those institutions...

BACKGROUND: Sustained growth in longevity raises questions as to why some individuals report a good quality of life in older ages, while others seem to suffer more markedly the effects of natural deterioration. Health-related quality of life (HRQL) is mediated by several easily measurable factors, including socio-demographics, morbidity, functional status and lifestyles. This study seeks to further our knowledge of these factors in order to outline a profile of the population at greater risk of poor ageing, and to identify those attributes that might be modified during younger stages of the life course...

Quantifying three-dimensional upper body kinematics can be a valuable method for assessing upper limb function. Considering that kinematic model characteristics, performed tasks, and reported outcomes are not consistently standardized and exhibit significant variability across studies, the purpose of this review was to evaluate the literature investigating upper body kinematics in non-disabled individuals via optical motion capture. Specific objectives were to report on the kinematic model characteristics, performed functional tasks, and kinematic outcomes, and to assess whether kinematic protocols were assessed for validity and reliability...

The use of cardiovascular progenitor cells (CPCs) to repair damaged myocardium has been the focus of intense research. Previous reports have shown that pretreatments, including hypoxia, improve cell function. However, the age-dependent effects of short-term hypoxia on CPCs, and the role of signaling in these effects, are unknown. Cloned neonatal and adult CPCs expressing Isl1, c-Kit, KDR, PDGFRA, and CXCR4, were preconditioned using hypoxia (1% O2 for six hours). Intracellular signaling pathway changes were modeled using Ingenuity Pathway Analysis (IPA), while qRT-PCR, flow cytometry, and immunoblotting were used to measure pathway activation...
