Wireless sensor networks have been considered as an effective solution to a wide range of applications due to their prominent characteristics concerning information retrieving and distributed processing. When visual information can be also retrieved by sensor nodes, applications acquire a more comprehensive perception of monitored environments, fostering the creation of wireless visual sensor networks. As such networks are being more often considered for critical monitoring and control applications, usually related to catastrophic situation prevention, security enhancement and crises management, fault tolerance becomes a major expected service for visual sensor networks...

Retrogenes are a class of functional genes derived from the mRNA of various intron-containing genes. PIPSL was created through a unique mechanism, whereby distinct genes were assembled at the RNA level, and the resulting chimera was then reverse transcribed and integrated into the genome by the L1 retrotransposon. Expression of PIPSL RNA via its transcription start sites (TSSs) has been confirmed in the testes of humans and chimpanzee. Here, we demonstrated that PIPSL RNA is expressed in the testis of the white-handed gibbon...

Multilingual children and language impairment Abstract. For many children with a migration background, difficulties acquiring their second language skills influences their educational success. Because of the wide range of languages and their varieties, which are not described linguistically in detail, development of reliable and valid assessment procedures is hindered. This results in a diagnostic dilemma, as children who have problems learning their second language, along with many other reasons, have to be distinguished from children suffering from a specific language impairment (SLI)...

Ultra-weak bioluminescence (UWL) is a physiological phenomenon widely existing in all the biological activities including human, animals, plants, etc., which reflects the energy metabolism of the organism. Since the last century, ultra-weak photon emission (UPE) has been applied to the study of the essence of meridians and acupoints of traditional Chinese medicine and obtained some results as the higher luminescence characteristics, but many problems remain unsolved due to the limitation of detection technology...

Tropical scleractinian corals are dependent to varying degrees on their photosymbiotic partners. Under normal levels of temperature and irradiance, they can provide most, but not all, of the host's nutritional requirements. Heterotrophy is required to adequately supply critical nutrients, especially nitrogen and phosphorus. Scleractinian corals are known as mesozooplankton predators, and most employ tentacle capture. The ability to trap nano- and picoplankton has been demonstrated by several coral species and appears to fulfill a substantial proportion of their daily metabolic requirements...

The interface between filler and hydration products can have a significant effect on the mechanical properties of the cement paste system. With different adhesion properties between filler and hydration products, the effect of microstructural features (size, shape, surface roughness), particle distribution and area fraction of filler on the fracture behavior of a blended cement paste system is supposed to be different, as well. In order to understand the effect of the microstructural features, particle distribution and area fraction of filler on the fracture behavior of a blended cement paste system with either strong or weak filler-matrix interface, microscale simulations with a lattice model are carried out...

Eight enantiomeric pairs of new meromonoterpenoids (1a/1b-8a/8b) and four known compounds (9-12) were isolated from Rhododendron nyingchiense. Their structures were established by spectroscopic methods, quantum chemical calculations, and X-ray crystallography. The enantiomeric pairs were acquired from scalemic mixtures by chiral-phase HPLC and showed diverse heterocyclic frameworks. Compounds 1a/1b possess a rare 6/7/5/5 heterocyclic system, and 2a/2b incorporate a new 6/6/3/5 heterocyclic system featuring a quinone motif...

Transthyretin (TTR), a plasma thyroid hormone distributor protein (THDP), emerged from 5-hydroxyisourate hydrolase (HIUHase), an enzyme involved in urate metabolism, by gene duplication at a stage of chordate evolution. Comparison of amino acid sequences revealed the presence of two His-rich segments in the primitive TTRs. Using several HIUHase and TTR mutants, we investigated 5-hydroxyisourate (HIU) hydrolysis activity and thyroid hormone (TH) binding activity to elucidate how a novel function as a THDP arose...

The World Health Organization regards betel quid (BQ) as a human carcinogen. The current study analyzes whether the BQ cues can elicit activity in the chewers' craving-related brain areas. We adopted a cue-reactivity paradigm to examine the changes in the brain activities. The urge intensity was also included to examine whether it can moderate the brain areas stimulated by BQ cues. Sixteen male BQ chewers and 16 healthy male controls were recruited and analyzed. Four types of cues were adopted: BQ cues, matched food cues, visual control cues, and resting crosshair cued...

Epithelial to mesenchymal transition (EMT) is one of the acquired resistance mechanisms to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in lung cancers. Since EMT is related to tumor invasion, metastases, and resistance to various treatments, it is important to prevent the emergence of EMT. However, molecular mechanism(s) underlying EMT phenotypic changes, as well as biomarker(s) that predict the emergence of EMT in EGFR-mutated lung cancers are unclear to date. Through the comparison of expression data between isogenic lung cancer cell lines that acquired resistance to EGFR-TKI(s), we identified that high CD44 expression is related to a mesenchymal phenotype, and that sh-RNA-mediated knockdown of CD44 reversed the EMT change...

Bacterial infections acquired in healthcare facilities including hospitals, the so called healthcare acquired or nosocomial infections, are still of great concern worldwide and represent a significant economical burden. One of the major causes of morbidity is infection with Methicillin Resistant Staphylococcus aureus (MRSA), which has been reported to survive on surfaces for several months. Bactericidal activity of copper-TiO2 thin films, which release copper ions and are deposited on glass surfaces and heated to high temperatures, is well known even when illuminated with very weak UVA light of about 10 μW/cm2...

Previous studies on cortical volume and thickness measures in autism spectrum disorders (ASD) show inconsistent results. We acquired structural magnetic resonance images of 30 individuals with ASD and individually matched controls and extracted surface-based and deformation-based morphometry measures. All participants had an IQ>100. Neither surface-based cortical thickness nor deformation based gyrification measures differed significantly across groups. Significant decreases but no increases of the gyrification index and sulcus depth could only be observed in the ASD group before correcting for multiple comparisons...

Hospital-acquired pneumonia (HAP) is an infection of the lung parenchyma. It is the second most frequent nosocomial infection and the leading cause of death from infection in critically ill patients. Hospital-acquired and, particularly, ventilator-associated pneumonia prolong the hospital stay and increase treatment costs. The clinical signs of pneumonia are rather non-specific, with limited possibilities to distinguish the lung condition from other nosological entities. The yield, effectiveness and cost of new rapid diagnostic procedures as well as early biochemical markers specific for pneumonia have not been sufficiently verified and clinical translation of technological innovations is slow...
