Background Muscles and tendons are subjected to a high level of stress in everyday life and sports. This often leads to injuries and is associated with training failure and reduced performance as well as with high costs for treatment and rehabilitation. Fast and successful treatment is therefore very important, both from an athletic and economic point of view. This study aims to demonstrate the relevance of biomechanical procedures for the objective monitoring of rehabilitation. At the same time, the results are to be used to establish progress and evaluation criteria for an efficient and controlled rehabilitation...

Controlling translation initiation is an efficient way to regulate gene expression at the post-transcriptional level. However, current knowledge regarding regulatory proteins and their modes of controlling translation initiation is still limited. In this study, we employed tandem affinity purification and mass spectrometry to screen for unknown proteins associated with the translation initiation machinery. Ubiquitin specific peptidase 9, X-linked (USP9X), was identified as a novel binding partner, that interacts with the eukaryotic translation initiation factor 4B (eIF4B) in a mRNA-independent manner...

Dermatophytes are keratinophilic fungi belonging to the family Arthrodermataceae. Despite having a monophyletic origin, its systematics has always been complex and controversial. Sequencing of nuclear ribosomal ITS and D1/D2 rDNA has been proposed as an efficient tool for identifying species in this group of fungi, while multilocus analyses have been used for phylogenetic species recognition. However, the search for new markers, with sequence and size variation, which enable species identification in only one polymerase chain reaction (PCR) step, is very attractive...

The human CST (Ctc1, Stn1 and Ten1) complex binds the telomeric overhang and regulates telomere length by promoting C-strand replication and inhibiting telomerase-dependent G-strand synthesis. Structural and biochemical studies on the human Stn1 and Ten1 complex revealed its mechanism of assembly and nucleic acid binding. However, little is known about the structural organization of the multi-domain Ctc1 protein and how each of these domains contribute to telomere length regulation. Here, we report the structure of a central domain of human Ctc1...

Mutations in tumors can create a state of increased cellular plasticity that promotes resistance to treatment. Thus, there is an urgent need to develop novel strategies for identifying key factors that regulate cellular plasticity in order to combat resistance to chemotherapy and radiation treatment. Here we report that prostate epithelial cell reprogramming could be exploited to identify key factors required for promoting prostate cancer tumorigenesis and cellular plasticity. Deletion of phosphatase and tensin homolog (Pten) and transforming growth factor-beta receptor type 2 (Tgfbr2) may increase prostate epithelial cell reprogramming efficiency in vitro and cause rapid tumor development and early mortality in vivo...

Arf, a well-established tumor suppressor, is either mutated or downregulated in a wide array of cancers. However, its role in hepatocellular carcinoma (HCC) progression is controversial. Conflicting observations have been published regarding its expression in HCC. In this study, we provide clear genetic evidence demonstrating a protective role of p19Arf in hepatocarcinogenesis. Using Ras-induced mouse model, we show that p19Arf deficiency accelerates progression of aggressive HCC in vivo. To investigate the role of p14ARF in human liver cancers, we analyzed its expression in human HCC using immunohistochemistry...

Background: Electroconvulsive therapy (ECT) is a fast acting and efficient treatment of depression used in the clinic. The underlying mechanism of its therapeutic effect is still unclear. However, recovery of synaptic connections and synaptic remodeling is thought to play a critical role for the clinical efficacy obtained from a rapid antidepressant response. Here, we investigated the relationship between, synaptic changes and concomitant non-neuronal changes in microvasculature and mitochondria, and it relationship to Brain-derived neurotrophic factor (BDNF) level changes after repeated electroconvulsive seizures (ECS), an animal model of ECT...

Microalgae are among the most productive biological systems for converting sunlight into chemical energy which is used to capture and transform inorganic carbon into biomass. The efficiency of CO2 capture depends on the cultivation system configuration (photobioreactors or open systems) and can vary according to the state of the algal physiology, the chemical composition of the nutrient medium and environmental factors, such as irradiance, temperature and pH. This mini-review is focused on some of the most important environmental factors determining photosynthetic activity, CO2 biofixation, cell growth rates and biomass productivities by microalgae...

Paracoccus denitrificans PD1222 accumulates short-length polyhydroxyalkanoates, poly(3-hydroxybutyrate), under nitrogen deficient conditions. Polyhydroxybutyrate metabolism requires the 3-ketoacyl-CoA thiolase PhaA, the acetoacetyl-CoA dehydrogenase/reductase PhaB, and the synthase PhaC for polymerization. Additionally, P. denitrificans PD1222 grows aerobically with nitrate as sole nitrogen source. Nitrate assimilation is controlled negatively by ammonium through the two-component NtrBC system. NtrB is a sensor kinase that autophosphorylates a histidine residue under low nitrogen concentrations and, in turn transfers a phosphoryl group to an aspartate residue of the response regulator NtrC protein, which acts as a transcriptional activator of the P...

Extensive production of SHV-14 beta-lactamase makes Klebsiella pneumoniae resistant to beta-lactams. The presence of omega-loop has been reported to influence the beta-lactamase activity, which is also present in SHV-14. Its omega-loop has three glutamates in nearly alternating positions, 162, 164 and 167 but their concise role on the behaviour of SHV-14 is unknown. To uncover the influence of each glutamate on SHV-14, we replaced glutamates with alanine and estimated the effect of each mutation by assessing the change in beta-lactam sensitivities in the surrogate Escherichia coli cells and catalytic efficiencies for hydrolysis with the purified proteins...

Thrombospondin-1 (THBS1) is an important mediator of corpus luteum (CL) regression. Highly induced during luteolysis, it acts as a natural anti-angiogenic, proapoptotic compound. THBS1 expression is regulated in bovine luteal endothelial cells (LECs) by fibroblast growth factor-2 (FGF2) and transforming growth factor-beta1 (TGFB1) acting in an opposite manner. In this study we sought to identify specific microRNAs (miRNAs) targeting THBS1 and investigate their possible involvement in FGF2 and TGFB1-mediated THBS1 expression...

Economic bubbles are an empirical puzzle because they do not readily fit the notion of an efficient market. We argue that bubbles are associated with a conflict and a gap in the allocation of effort during negotiation by sellers and buyers. We examined 21 experimental asset markets where in one condition players could buy and sell and in the other they could either buy or sell. The results indicated that when making concurrent buying and selling decisions the mean number of asks for sellers was 71% higher than the number of bids for buyers...

Olfactory ensheathing cell (OEC) transplantation is a promising strategy for treating spinal cord injury (SCI), as has been demonstrated in experimental SCI models and naturally occurring SCI in dogs. However, the presence of chondroitin sulphate proteoglycans within the extracellular matrix of the glial scar can inhibit efficient axonal repair and limit the therapeutic potential of OECs. Here we have used lentiviral vectors to genetically modify canine OECs to continuously deliver mammalian chondroitinase ABC at the lesion site in order to degrade the inhibitory chondroitin sulphate proteoglycans in a rodent model of spinal cord injury...

Our ability to perform arithmetic relies heavily on working memory, the manipulation and maintenance of information in mind. Previous research has found that in adults, procedural strategies, particularly counting, rely on working memory to a greater extent than retrieval strategies. During childhood there are changes in the types of strategies employed, as well as an increase in the accuracy and efficiency of strategy execution. As such it seems likely that the role of working memory in arithmetic may also change, however children and adults have never been directly compared...
