BACKGROUND/AIM: The decision as to whether teeth in the line of jaw fractures should be extracted or retained remains a controversial issue. The aim of this study was to assess the prognosis of teeth directly in the line of, and adjacent to jaw fracture sites. MATERIALS AND METHODS: The study consisted of 50 patients with facial fractures in the dentate region, the diagnosis of which was made on the basis of clinical and radiographic examinations. A total of 124 teeth were present in 69 fracture sites (50 patients), of which 89 teeth were evaluated both, clinically (tooth mobility, pocket depth, pulp sensibility) and with periapical radiographs (degree of fracture displacement, marginal bone loss, root resorption)...

Today Miliary Tuberculosis in Central Europe is a rare disease, quite often with resulting diagnostic uncertainty. The terms "miliary" and "tubercle" are outlined with their up to now accepted historical roots. An analysis of Marcello Malpighi's quite unknown post-mortem reports by the Italian author L. Munster reveals an earlier use of both terms than described till now.

Memetic Algorithms are population-based metaheuristics intrinsically concerned with exploiting all available knowledge about the problem under study. The incorporation of problem domain knowledge is not an optional mechanism, but a fundamental feature of the Memetic Algorithms. In this paper, we present a Memetic Algorithm to tackle the three-dimensional protein structure prediction problem. The method uses a structured population and incorporates a Simulated Annealing algorithm as a local search strategy, as well as ad-hoc crossover and mutation operators to deal with the problem...

A total of 208 therapists and therapists-in-training were surveyed to better understand if clinical assessments and recommendations regarding "sex addiction" changed based upon a client's gender, relationship status, or exclusivity status. Using clinical vignettes, this study examined the clinical assessment and recommendations of licensed mental health providers (n = 92) and mental health providers in-training (n = 116). Results indicated that professional ratings differed based on relationship exclusivity and gender; specifically, female nonmonogamous behavior was rated more negatively than male nonmonogamous behavior, while male monogamous behavior was rated more negatively than female monogamous behavior...

Lindera aggregate (Sims) Kosterm root has been used in traditional Chinese medicine for the treatment of rheumatism palsy, dyspepsia and frequent urination for a long history. Norisoboldine (NOR), the main active constituent of this herb drug, possesses outstanding anti-arthritis activity. However, in vivo disposition of NOR has been known to a limited extent, especially under the pathological condition of rheumatoid arthritis (RA). The aim of this study is to investigate whether and how the absorption of NOR is altered in adjuvant-induced arthritis (AIA) rats...

Short day length-induced alteration of potassium (K) localization in perennial trees is believed to be a mechanism for surviving and adapting to severe winters. To investigate the relationship between cesium (Cs) and K localizations, a model tree poplar, hybrid aspen T89, was employed. Under short day length conditions, the amount of (137)Cs absorbed through the root and translocated to the root was drastically reduced, but (42)K was not. Potassium uptake from the rhizosphere is mediated mainly by KUP/HAK/KT and CNGC transporters...

It is generally known that gold nanoparticles are localised in the cytoplasm and, if synthesised in small sizes or functionalized with specific proteins, they enter the cell nucleus. However, there is no report emphasising the importance of surface functionalization in their accumulation in the nucleolus. Here, for the first time in the literature, it is proposed that functionalization of gold nanoparticles with a thin layer of polyethyleneimine (PEI) spearheads them to the nucleolus of hard-to-transfect post-mitotic dorsal root ganglion neurones in a size-independent manner...

Cells respond to changes in their environment, to developmental cues, and to pathogen aggression through the action of a complex network of proteins. These networks can be decomposed into a multitude of signaling pathways that relay signals from the microenvironment to the cellular components involved in eliciting a specific response. Perturbations in these signaling processes are at the root of multiple pathologies, the most notable of these being cancer. The study of receptor tyrosine kinase (RTK) signaling led to the first description of a mechanism whereby an extracellular signal is transmitted to the nucleus to induce a transcriptional response...

Nitrogen (N) and phosphorus (P) deposition are increasing worldwide largely due to increased fertilizer use and fossil fuel combustion. Most work with N and P deposition in natural ecosystems has focused on temperate, highly industrialized, regions. Tropical regions are becoming more developed, releasing large amounts of these nutrients into the atmosphere. Nutrient enrichment in nutrient-poor systems such as tropical montane forest can represent a relatively large shift in nutrient availability, especially for sensitive microorganisms such as arbuscular mycorrhizal fungi (AMF)...

The ability of nanoparticles to alter protein structure and dynamics plays an important role in their medical and biological applications. We investigate allosteric effects of gold nanoparticles on human serum albumin protein using molecular simulations. The extent to which bound nanoparticles influence the structure and dynamics of residues distant from the binding site is analyzed. The root mean square deviation, root mean square fluctuation and variation in the secondary structure of individual residues on a human serum albumin protein are calculated for four protein-gold nanoparticle binding complexes...

Qiaoqiao Teng, Han Vinh Huynh
The properties and reactivities of transition metal complexes are rooted in the stereoelectronic properties of their ligands. While the bulk of a ligand can be easily evaluated and compared by the drawing of its Lewis structure, prediction on the electronic contributions is often less straightforward. Thus, several electronic parameters have been developed for the experimental evaluation of ligands throughout the years. This article accounts for the most recent one developed by the Huynh group, which employs (13)C NMR spectroscopy to determine ligand donor strengths using N-heterocyclic carbene complexes...

Certain cultivars of some crops, including durum wheat (Triticum durum Desf.), have a propensity to accumulate cadmium in the grain. In the 1980s, a Canadian wheat breeding program generated five pairs of near-isogenic lines of durum wheat that vary in cadmium-accumulation. Within each pair, one member accumulates twofold to threefold higher concentrations of cadmium in the shoot and grain. However, the physiological explanation for the high-low phenotype is unknown. We studied correlations between concentrations of cadmium and non-protein thiols, including phytochelatins, in these five pairs of near-isogenic lines to test the hypothesis that differential retention of cadmium-binding complexes in the root would explain the phenotype...
