Diets, but also overall food environments, comprise a variety of significant factors with direct and indirect impacts on human health. Eco-Regions are geographical areas with a territorial approach to rural development, utilizing organic food and farming practices, and principles and promoting sustainable communities and food systems. However, so far, little attention has been given to quantifying aspects of the health of citizens living in these sustainable transition territories.

Background: Drug desensitization allows for safe administration of a drug to a patient with a previous hypersensitivity reaction. Successful desensitization protocols have been described for different medications, including protocols for oncology patients. Few cases of desensitization to sorafenib and imatinib have been described in the literature so far.

Excessive synthesis of type I collagen is a hallmark of fibrotic diseases. Binding of La-related protein 6 (LARP6) to the 5' stem-loop (5'SL) of collagen mRNAs regulates their translation leading to an unnaturally elevated rate of collagen biosynthesis in fibrosis. Previous work suggested that LARP6 needs two domains to form stable complex with 5'SL RNA, the La domain and the juxtaposed RNA recognition motif (RRM), jointly called the La-module.

Mechanistic aspects of type I procollagen biosynthesis in cells are poorly understood. To provide more insight into this process we designed a system to directly image type I procollagen biogenesis by co-expression of fluorescently labeled full size procollagen α1(I) and one α2(I) polypeptides. High resolution images show that collagen α1(I) and α2(I) polypeptides are produced in coordination in discrete structures on the ER membrane, which we termed the collagenosomes.

Burnout is a special a state of physical or emotional exhaustion that also involves a sense of reduced accomplishment and loss of personal identity. To evaluate the predictors of burnout among work staff in the seven private agencies for support and defense of persons and their property. We performed a multicentric cross-sectional study that involved representative sample of working staff from Agencies of Private Security in Central Serbia.

Fibrosis is defined by excessive production of type I collagen in various organs. Excessive type I collagen production in fibrosis is stimulated by binding of RNA protein LARP6 to the structural element of collagen mRNAs, the 5' stem loop (5'SL). The LARP6-dependent regulation is specific for type I collagen and critical for fibrosis development.

Fibrosis is characterized by excessive production of type I collagen. Biosynthesis of type I collagen in fibrosis is augmented by binding of protein LARP6 to the 5' stem-loop structure (5'SL), which is found exclusively in type I collagen mRNAs. A high throughput screen was performed to discover inhibitors of LARP6 binding to 5'SL, as potential antifibrotic drugs.

IntroductionThis paper reviews the current knowledge and understanding of spp and spp. in humans, animals and the environment in 10 countries in the eastern part of Europe: Bosnia and Herzegovina, Croatia, Czech Republic, Estonia, Hungary, Latvia, Poland, Romania, Serbia and Slovenia. Published scientific papers and conference proceedings from the international and local literature, official national health service reports, national databases and doctoral theses in local languages were reviewed to provide an extensive overview on the epidemiology, diagnostics and research on these pathogens, as well as analyse knowledge gaps and areas for further research.

Type I collagen is composed of 2 polypeptides, α1(I) and α2(I), which fold into triple helix. Collagen α1(I) and α2(I) mRNAs have a conserved stem-loop structure in their 5' UTRs, the 5'SL. LARP6 binds the 5'SL to regulate type I collagen expression.

Fibroproliferative diseases are one of the leading causes of death worldwide. They are characterized by reactive fibrosis caused by uncontrolled synthesis of type I collagen. There is no cure for fibrosis and development of therapeutics that can inhibit collagen synthesis is urgently needed.

Purpose: Differentiated thyroid microcarcinoma (DTM) has a good prognosis and survival, but recurrent disease may appear during follow-up. The aim of this study was to evaluate the influence of initial treatment including surgery and radioactive iodine (131I) on the survival and recurrence in patients with DTM.

Methods: Between January 1979 and December 2006, 130 patients with DTM were retrospectively evaluated, with a median follow-up of 10 years.

Aim: To elucidate the role of cytokine receptor-like factor 1 (CRLF1) in hepatic stellate cells and liver fibrosis.

Methods: Rat hepatic stellate cells (HSCs) were isolated by Nykodenz gradient centrifugation and activated by culturing in vitro. Differentially expressed genes in quiescent and culture activated HSCs were identified using microarrays.

Introduction: Polymiositis belongs to the group of inflammatory myopathies which are manifested by muscle weakness of the shoulder blade and pelvic region. The presence of typical skin manifestations is suggestive of dermatomyositis. These patients may also develop dysphagia (10-54%) as a result of involvement of the oropharyngeal and upper oesophageal striated muscles.

Type I collagen is the most abundant protein in human body. Fibrosis is characterized by excessive synthesis of type I collagen in parenchymal organs. It is a leading cause of morbidity and mortality worldwide, about 45% of all natural deaths are attributable to some fibroproliferative disease.

Type I collagen, synthesized in all tissues as the heterotrimer of two alpha1(I) polypeptides and one alpha2(I) polypeptide, is the most abundant protein in the human body. Here we show that intact nonmuscle myosin filaments are required for the synthesis of heterotrimeric type I collagen. Conserved 5' stem-loop in collagen alpha1(I) and alpha2(I) mRNAs binds the RNA-binding protein LARP6.

Type I collagen is the most abundant protein in the human body, produced by folding of two alpha1(I) polypeptides and one alpha2(I) polypeptide into the triple helix. A conserved stem-loop structure is found in the 5' untranslated region of collagen mRNAs, encompassing the translation start codon. We cloned La ribonucleoprotein domain family member 6 (LARP6) as the protein that binds the collagen 5' stem-loop in a sequence-specific manner.

Background: Differentiated thyroid carcinoma (DTC) usually has a good prognosis and rarely develops distant metastases. Although it might be expected that avid radioiodine uptake in distant metastases would be associated with a favorable outcome, there are few long-term studies regarding this. The present study was performed to evaluate the influence of radioiodine uptake in distant metastases on the disease-specific survival (DSS) in DTC patients.

Although microsatellite mutation rates generally increase with increasing length of the repeat tract, interruptions in a microsatellite may stabilize it. We have performed a direct analysis of the effect of microsatellite interruptions on mutation rate and spectrum in cultured mammalian cells. Two mononucleotide sequences (G(17) and A(17)) and a dinucleotide [(CA)(17)] were compared with interrupted repeats of the same size and with sequences of 8 repeat units.

The purpose was to analyze survival and its predicting factors in differentiated thyroid carcinoma (DTC) patients with distant metastases (M1). Radioiodine ((131)I) therapy was performed in 363 DTC patients from 1977 to 2000. Among 75 patients, 44 patients had M1 at the time of initial therapy and 31 patients had M1, which developed during the follow up.
