Notes

Grams protein-coupled excess estrogen receptor-1 enhances excitatory synaptic reactions inside the entorhinal cortex.
Transfer-of-training effects included measures of short-term memory, cognitive speed, math and reading fluency, complex reasoning, and ADHD symptoms.

Performance on 5/7 criterion measures indicated that shortened-length CWMT conferred as much benefit on WM performance as did standard-length training, with both CWMT groups improving more than the waitlist-control group. Only 2 of these findings remained robust after correcting for multiple comparisons. Follow-up analyses revealed that post-training improvements on WM performance were maintained for at least three months. There was no evidence of any transfer effects but the standard-length group showed improvement in task-specific strategy use.

This study failed to find robust evidence of benefits of standard-length CWMT for improving WM in college students with ADHD and the overall pattern of findings raise questions about the specificity of training effects.

Recent genome-wide association studies have identified several loci influencing lipid levels. The present study focused on the triglycerides (TG)-associated locus, the APOA4-APOA5-ZNF259-BUD13 gene cluster on chromosome 11, to explore the role of genetic variants in this gene cluster in the development of increasing TG levels and coronary heart disease (CHD).

Six single nucleotide polymorphisms (SNPs), rs4417316, rs651821, rs6589566, rs7396835, rs964184 and rs17119975, in the APOA4-APOA5-ZNF259-BUD13 gene cluster were selected and genotyped in 5374 healthy Chinese subjects. There were strong significant associations between the six SNPs and TG levels (P < 1.0 × 10(-8)). Moreover, a weighted genotype score was found to be associated with TG levels (P = 3.28 × 10(-13)). The frequencies of three common haplotypes were observed to be significantly different between the high TG group and the low TG group (P < 0.05). However, no significant effects were found for the SNPs regarding susceptibility to CHD in the Chinese case-control populations.

This study highlights the genotypes, genotype scores and haplotypes of the APOA4-APOA5-ZNF259-BUD13 gene cluster that were associated with TG levels in a Chinese population; however, the genetic variants in this gene cluster did not increase the risk of CHD in the Chinese population.

Future dentists will, after all, be confronted with new guidelines and need to be able to integrate them in their daily practice. Various guidelines and protocols have been established within the 3 dental schools. For students and instructors, however, the motivation for these guidelines and protocols is not always sufficiently clear. In addition, the terms guideline, clinical practice guideline and protocol are used interchangeably, resulting in terminological confusion. Embedding within and coordination with theoretical education is also still limited in all programmes and it is proposed that the 3 dental schools collaborate on this issue. Finally, it is advised to replace the term 'evidence-based' with 'evidence-informed' because this indicates more clearly that other factors (patients opinion, available financial means, etc.) play a role in the final choice of treatment in a specific situation.Systems for cone-beam computed tomography make a high-quality 3D reconstruction of dentomaxillofacial structures possible, without exposing the patient to excessive doses of radiation. Due to its 3D nature cone-beam computed tomography is superior to conventional dental radiographic imaging methods for many aspects of endodontic diagnosis and treatment planning. There are multiple indications for the use of cone-beam computed tomography scans in endodontics, including detection of periapical lesions or root fractures and the exploration of the root canal anatomy and its deviations. Depending on conditions, a judicious decision will always have to be made with regard to the radiographic technique to be applied. Primary in that respect must be the means by which the most accurate diagnostic image can be achieved with the lowest possible dose of radiation. Making a cone-beam computed tomography scan is justified only when the required diagnostic information cannot be achieved adequately using lower dose conventional dental radiographic imaging techniques.In 1990, the thesis 'Removable complete dentures in older people, an issue dealing with adaptability?' was published. Among other things, this thesis aimed at finding a method of measuring older people's adaptability to removable complete dentures. Its conclusion was that a subscale of the "Beoordelingsschaal voor Oudere Patiënten" (Rating scale for older patients) had predictive value. Subsequently, only a few research projects on this topic have been carried out. They dealt with demonstrated adaptation achieved after treatment, the realised adaptation. The results were disappointing. Ever since the availability of endosseous oral implants, research into adaptability to conventional removable complete dentures seems less relevant. During the last decades, inquiries into a method of measuring treatment effectiveness has focused on older people's quality of life and general health condition. However, to assess with respect to oral health care an older person's general health condition and load-taking capacity adequately, some experience is indispensable.A twenty-year-old man was referred to an orthodontist for orthodontic re-treatment of dental element 32 by his dentist and a periodontist. At the buccal surface of the dental element a significant gingival resorption had occurred and the root of the element was located outside of the processus alveolaris buccally. This case will be presented at the thematic tour 'Door de beugel team up' on 27 October 2015, which is organised by the Nederlandse Vereniging van Tandartsen (Dutch Dentists' Society) and will be held at 4 different locations in the Netherlands. Readers of the Nederlands Tijdschrift voor Tandheelkunde get an exclusive preview of the case. The treatment of choice will be published in the December 2015 issue.Coeliac disease is a chronic autoimmune enteropathy, which is caused by exposure to dietary gluten in genetically pre-disposed individuals. -Approximately 0.5-1% of the Dutch population has coeliac disease, diag-nosed at both younger and older age. Treatment consists of a strict gluten-free diet. Symptoms can be diverse, including dental and oral manifestations. These dental and oral manifestations are often seen in patients with coeliac disease, although most of them are nonspecific. This is not the case for the symmetric enamel defects described by Aine and colleagues, which are very specific for coeliac disease. Early diagnosing of coeliac disease is important to prevent complications by (vitamin) deficiencies or rare (pre) malignant forms of coeliac disease. There seems to be a role for dentists in early diagnosing of coeliac disease.The crystal structures of monomeric RNA-dependent RNA polymerases and reverse transcriptases of more than 20 different viruses are available in the Protein Data Bank. They all share the characteristic right-hand shape of DNA- and RNA polymerases formed by the fingers, palm and thumb subdomains, and, in many cases, "fingertips" that extend from the fingers towards the thumb subdomain, giving the viral enzyme a closed right-hand appearance. Six conserved structural motifs that contain key residues for the proper functioning of the enzyme have been identified in all these RNA-dependent polymerases. These enzymes share a two divalent metal-ion mechanism of polymerization in which two conserved aspartate residues coordinate the interactions with the metal ions to catalyze the nucleotidyl transfer reaction. The recent availability of crystal structures of polymerases of the Orthomyxoviridae and Bunyaviridae families allowed us to make pairwise comparisons of the tertiary structures of polymerases belonging to the four main RNA viral groups, which has led to a phylogenetic tree in which single-stranded negative RNA viral polymerases have been included for the first time. This has also allowed us to use a homology-based structural prediction approach to develop a general three-dimensional model of the Ebola virus RNA-dependent RNA polymerase. Our model includes several of the conserved structural motifs and residues described in other viral RNA-dependent RNA polymerases that define the catalytic and highly conserved palm subdomain, as well as portions of the fingers and thumb subdomains. The results presented here help to understand the current use and apparent success of antivirals, i.e. Brincidofovir, Lamivudine and Favipiravir, originally aimed at other types of polymerases, to counteract the Ebola virus infection.Cancer stem cells (CSCs) possess capacity to both self-renew and generate all cells within a tumor, and are thought to drive tumor recurrence. Targeting the stem cell niche to eradicate CSCs represents an important area of therapeutic development. The complex nature of many interacting elements of the stem cell niche, including both intracellular signals and microenvironmental growth factors and cytokines, creates a challenge in choosing which elements to target, alone or in combination. Stochastic stimulation techniques allow for the careful study of complex systems in biology and medicine and are ideal for the investigation of strategies aimed at CSC eradication. We present a mathematical model of the breast cancer stem cell (BCSC) niche to predict population dynamics during carcinogenesis and in response to treatment. Selleckchem Bcl-2 inhibitor Using data from cell line and mouse xenograft experiments, we estimate rates of interconversion between mesenchymal and epithelial states in BCSCs and find that EMT/MET transitions occur frequently. We examine bulk tumor growth dynamics in response to alterations in the rate of symmetric self-renewal of BCSCs and find that small changes in BCSC behavior can give rise to the Gompertzian growth pattern observed in breast tumors. Finally, we examine stochastic reaction kinetic simulations in which elements of the breast cancer stem cell niche are inhibited individually and in combination. We find that slowing self-renewal and disrupting the positive feedback loop between IL-6, Stat3 activation, and NF-κB signaling by simultaneous inhibition of IL-6 and HER2 is the most effective combination to eliminate both mesenchymal and epithelial populations of BCSCs. Predictions from our model and simulations show excellent agreement with experimental data showing the efficacy of combined HER2 and Il-6 blockade in reducing BCSC populations. Our findings will be directly examined in a planned clinical trial of combined HER2 and IL-6 targeted therapy in HER2-positive breast cancer.
