OBJECTIVE: Thyroid hormone has well recognized effects on the cardiovascular system. The purpose of this study was to define the influence of treatment of either hypothyroidism and hyperthyroidism on the values and circadial variations of arterial blood pressure measured by ambulatory blood pressure monitoring. MATERIAL AND METHODS: The study was carried out on 30 hypothyroidic and 30 hyperthyroidic patients without hypertension and 46 healthy participants. First, all the parameters of the groups, then blood pressure values obtained by ambulatory blood pressure monitoring before and after treatment (thyroid hormone replacement with levothyroxine and antithyroid treatment either with propylthyrouracil or metimazole) were compared...

Radiotherapy is ubiquitous in the treatment of patients with both primary brain tumors as well as disease which is metastatic to the brain. This therapy is not without cost, however, as cognitive decline is frequently associated with cranial radiation, particularly with whole brain radiotherapy (WBRT). The precise mechanisms responsible for radiation-induced morbidity remain incompletely understood and continue to be an active area of ongoing research. In this article, we review the hypothetical means by which cranial radiation induces cognitive decline as well as potential therapeutic approaches to prevent, minimize or reverse treatment-induced cognitive deterioration...

BACKGROUND/AIM: There is an urgent need to investigate the long-term impact of social skill interventions for children with attention deficit hyperactivity disorder (ADHD). Interventions targeting the social skills of children with ADHD have limited short-term effectiveness and rarely investigate the long-term impact. Furthermore, these interventions are most frequently conducted in the clinic setting, without including the child's natural settings and interactants, such as their regular playmates and parents...

Idiopathic pneumonia syndrome (IPS) is a common, often fatal, complication following hematopoietic stem cell transplantation (HSCT) characterized by severe pneumonitis and interstitial fibrosis. Fully reconstituted syngeneic bone marrow transplant (BMT) mice infected with murine γ-herpesvirus-68 develop interleukin-17 (IL-17)-driven pneumonitis and fibrosis, which mimics clinical manifestations of IPS. We found CD103+ and CD11b+ dendritic cells (DCs) are selectively deficient for the Notch ligand, DLL4, following BMT and CD4+ T cells isolated from lungs and spleens of infected BMT mice display Notch signaling defects...

Water keeps puzzling scientists because of its numerous properties which behave oppositely to usual liquids: for instance, water expands upon cooling, and liquid water is denser than ice. To explain this anomalous behaviour, several theories have been proposed, with different predictions for the properties of supercooled water (liquid at conditions where ice is stable). However, discriminating between those theories with experiments has remained elusive because of spontaneous ice nucleation. Here we measure the sound velocity in liquid water stretched to negative pressure, and derive an experimental equation of state, which reveals compressibility anomalies...

Vanadium is a transition metal that has a unique and beneficial effect on both humans and animals. For many years, studies have suggested that vanadium is an essential trace element. Its biological properties are of interest due to its therapeutic potential, including in the treatment of diabetes mellitus. Vanadium deficiencies can lead to a range of pathologies. However, excessive concentration of this metal can cause irreversible damage to various tissues and organs. Vanadium toxicity mainly manifests in gastrointestinal symptoms, including diarrhea, vomiting, and weight reduction...

BACKGROUND: General anesthesia and endotracheal intubation are a luxury rather than a necessity for many video-assisted thoracic surgery (VATS) operations. Twenty-three years ago the author began utilizing local anesthesia and sedation for pleural disease and subsequently for pericardial and lung disease. STUDY DESIGN: The records of all patients undergoing VATS utilizing local anesthesia and sedation at hospitals of the Geisinger Health System (Danville and Wilkes-Barre, PA) June 1, 2002 to June 30, 2011 and the Lifebridge Health System (Baltimore, MD) July 1, 2011 to March 1, 2017 were retrospectively reviewed...

In recent years photodynamic therapy (PDT) has received widespread attention in cancer treatment due to its smaller surgical trauma, better selectivity towards tumor cells, reduced side effects and possibility of repeatable treatment. Since cancer is the second cause of death worldwide, scientists constantly seek for new potential therapeutic agents including nanotechnology-based photosensitizers used in PDT. The new-designed nanostructures must be carefully studied and well characterized what require analytically useful and powerful tools that enable real progress in nanoscience development...

Recent studies have shown that subcutaneous or subfascial pacemaker- and ICD implantation with continued oral anticoagulation therapy is associated with lower risk for bleeding complications, when compared to heparin bridging strategies. However, ICD generators are often implanted submuscularly. We therefore compared the bleeding risk with continued phenprocoumon therapy vs. heparin bridging in patients receiving submuscular ICD implantation. Between 01/2013 and 12/2013, 104 patients with need for oral anticoagulation received submuscular ICD or CRT-D implantation in our institution...

The purpose of this study was to test a conceptual model linking parental support and parental physical activity (PA), with children's perception of parental support and children's PA. Baseline data were drawn from the Grade 5 ACT-i-Pass community-based PA intervention conducted in London, Ontario between May and October 2014. Parent and child PA were measured using the International Physical Activity Questionnaire and Physical Activity Questionnaire for Children, respectively. Questions pertaining to parental support and children's perception of that parental support were obtained via questionnaires...

As technologies change, MG-RAST is adapting. Newly available software is being included to improve accuracy and performance. As a computational service constantly running large volume scientific workflows, MG-RAST is the right location to perform benchmarking and implement algorithmic or platform improvements, in many cases involving trade-offs between specificity, sensitivity and run-time cost. The work in [Glass EM, Dribinsky Y, Yilmaz P, et al. ISME J 2014;8:1-3] is an example; we use existing well-studied data sets as gold standards representing different environments and different technologies to evaluate any changes to the pipeline...

OBJECTIVE: The aim of this study was to induce artificial caries in human sound dentin by means of a microcosm model using human saliva as source of bacteria and to apply a novel dual-energy micro-CT technique to quantify biofilm formation and evaluate its demineralization potential. DESIGN: Eight sound third molars had the occlusal enamel removed by cutting with a diamond disk and five cylindrical cavities (±2mm diameter; ±1.5mm depth) were prepared over the dentin surface in each specimen (n=40 cavities)...

BACKGROUND: Animal studies have shown that irisin is a myokine secreted following physical exercise, and that it induces the remodeling of white adipose tissue toward brown adipose tissue. Therefore, a protective role of irisin against obesity, diabetes, and other metabolic and cardiovascular conditions has been hypothesized. However, data in humans are contradictory and few data are available concerning the general population. AIMS: We aimed to evaluate the association between serum irisin concentrations and habitual physical activity, as well as other metabolic and cardiovascular factors in a general population in a Mediterranean area...

Metaproteomic analysis targets proteins, the catalytic entities in the habitat, thereby providing direct insights into the metabolic activity of the community studied. A major challenge still remaining for metaproteomics is the effective and comprehensive extraction of proteins from environmental samples, due to their high complexity with respect to organismic diversity and abundance range. Moreover, in certain habitats, the inherent matrix may interfere with protein extraction. In recent years, several studies reported different protein extraction methods for soils known for their complex geochemistry, but only two analyzed marine sediments that generally comprise different though similarly complex geochemistry...

The independent and central role of the patient with a complex chronic respiratory disease in targeted, personalized disease management strategies is becoming increasingly important. Patients are the ones living with the disease and are finally responsible for their lives underlining their role as essential members of the interdisciplinary treatment team. Areas covered: The present paper narratively reviews existing research and discusses the special, as well as specialized, role of the patient with a complex chronic respiratory disease in the healthcare system and highlights fundamental elements of the (future) relationship between patient and healthcare professionals...

Treatment of neovascular age-related macular degeneration (AMD) with anti-vascular endothelial growth factor agents has been improved since its introduction in Germany. Several observational studies have demonstrated an increased frequency of injections in parallel with improved visual outcomes during the first year of treatment over the last 7 years. These results are reflected in several case series. However, studies with a longer follow-up reported that visual function regressed to baseline vision following an initial improvement, e...

BACKGROUND: This study assessed Staphylococcus aureus infection risk in patients with type 2 diabetes mellitus (T2DM) undergoing an orthopedic knee, hip, or spine surgery. PATIENTS AND METHODS: All patients with a diagnosis of T2DM in the period from 2010 to 2012 were identified from a German claims database. First inpatient knee, hip, or spine surgery was used as index date. Cumulative incidence of S. aureus infections was calculated for several time intervals...

Manufacturable nanodevices must now be the predominant goal of nanotechnological research to ensure the enhanced properties of nanomaterials can be fully exploited and fulfill the promise that fundamental science has exposed. Here, we test the electrical stability of Au nanocatalyst-ZnO nanowire contacts to determine the limits of the electrical transport properties and the metal-semiconductor interfaces. While the transport properties of as-grown Au nanocatalyst contacts to ZnO nanowires have been well-defined, the stability of the interfaces over lengthy time periods and the electrical limits of the ohmic or Schottky function have not been studied...

Plant phenols may accumulate in end-stage kidney disease. The effect of hemodialysis on their plasma concentration remains poorly determined. Contingent on concentration, health-promoting or noxious effects occur; therefore, we assessed plasma concentration in hemodialyzed patients. In total, 21 maintenance hemodialyzed patients with diuresis < 500 mL per day (with oliguria), nine hemodialyzed patients with diuresis ≥ 500 mL per day (without oliguria) and 31 healthy volunteers were included. Nine phenolic acids were identified with high-performance liquid chromatography and total polyphenol concentration was determined with the Folin-Ciocalteu method in pre- or post-hemodialysis plasma and pre- or intra-hemodialysis dialysate...
