Near-Infrared spectroscopy (NIRs) coupled to chemometrics was investigated for the first time as a new tool for the analysis of black toners to evaluate its application in forensic cases. Ten black toners from four manufacturers were included in this study and the acquired spectra were compared in order to differentiate toners. Multivariate statistical analysis based on Principal Component Analysis (PCA) was considered to develop a model of comparison of toners in questioned documents. Results demonstrated the capabilities of the approach NIR/Chemometrics to correctly identify toners when printed on different papers and to be not affected by the printing process...

Fotini Boufidou, Angelos Halaris
The concept of neuroprogression describes the progressive course of the disorder and stresses the progressive, recurrent, and chronic course of the disease entity under consideration. It subsumes clinical manifestations of the disease process and may also entail morphological, biochemical, neurochemical, immunological, physiological, and genetic aspects that contribute to the progressive course of the disease in question. In an attempt to identify the appropriate agent or method that could arrest neuroprogression in psychiatric patients, we conducted an evaluation of the use of anti-inflammatory drugs under the perspective of current pharmacological and neurophysiological data...

BACKGROUND: Mammary analogue secretory carcinoma (MASC) of the salivary gland shows morphologic similarities and shares an immunophenotype and characteristic ETV6-NTRK3 translocation with secretory carcinoma of the breast. We present a buccal case of MASC along with a survey-based debate about its cytologic diagnosis by fine-needle aspiration (FNA). CASE: FNA of the buccal nodule of a 58-year-old Japanese man was initially performed by 3 cytologists who gave different assessments of the Papanicolaou classification (i...

Yu-Shu Huang, Christian Guilleminault
Pediatric obstructive sleep apnea (OSA) was initially described in 1976. In 1981, Dr. Guilleminault emphasized that pediatric OSA was different from the clinical presentation reported in adults. It was characterized by more disturbed nocturnal sleep than excessive daytime sleepiness, and presented more behavioral problems, particularly school problems, hyperactivity, nocturnal enuresis, sleep terrors, depression, insomnia, and psychiatric problems. The underlying causes of pediatric OSA are complex. Such factors as adenotonsillar hypertrophy, obesity, anatomical and neuromuscular factors, and hypotonic neuromuscular disease are also involved...

The continuous culture of Plasmodium falciparum is often seen as a means to an end, that end being to probe the biology of the parasite in question, and ultimately for many in the malaria drug discovery arena, to identify means of killing the parasite in order to treat malaria. In vitro continuous culture of Plasmodium falciparum is a fundamental requirement when undertaking malaria research where the primary objectives utilise viable parasites of a desired lifecycle stage. This investigation, and resulting data, compared the impact culturing Plasmodium falciparum long term (4 months) in different environmental conditions had on experimental outcomes and thus conclusions...

Thermodynamic properties are often modeled by classical force fields which describe the interactions on the atomistic scale. Molecular simulations are used for retrieving thermodynamic data from such models and many simulation techniques and computer codes are available for that purpose. In the present round robin study, the following fundamental question is addressed: Will different user groups working with different simulation codes obtain coinciding results within the statistical uncertainty of their data? A set of 24 simple simulation tasks is defined and solved by five user groups working with eight molecular simulation codes: DL_POLY, GROMACS, IMC, LAMMPS, ms2, NAMD, Tinker, and TOWHEE...

PURPOSE AND HYPOTHESIS: Although sex- and gender-specific analyses have been gaining more attention during the last years they have rarely been performed in orthopaedic literature. The primary purpose of this study was to investigate whether for injuries of the UCL the specific location of the rupture is influenced by sex. A secondary study question addressed the sex-independent effect of trauma intensity on the rupture site of the UCL. METHODS: This study is a retrospective analysis of all patients with either a proximal or distal bony avulsion or with a mid-substance tear or ligament avulsion of the UCL treated surgically between 1992 and 2015 at two level-I trauma centres...

Werner syndrome (WS) is a rare inheritable progeroid syndrome caused by a mutation in the WRN gene. Although WS has been described as a characteristic appearance of very slender extremities with a stocky trunk, few studies have investigated the loss of muscle mass, fat mass distribution (body composition), and mobility according to age and sex. Therefore, the aim of this study was to precisely describe the body composition in WS. Nine Japanese patients with WS (four males and five females; mean age 48±8.8 years) were recruited...

BACKGROUND: Patient review and restriction programs (PRRPs), used by state Medicaid programs to limit potential abuse and misuse of opioids and related controlled medications, often restrict members to a single pharmacy for controlled medications. While most states use a restricted pharmacy access model, not all states include restricted prescriber access. Oklahoma Medicaid (MOK) added a restricted prescriber access feature to its PRRP in July 2014. OBJECTIVE: To evaluate the incremental effect that the addition of a prescriber restriction to MOK's pharmacy-only PRRP had on the pharmacy and resource utilization of the enrolled members...

Metal borides have mostly been studied as bulk materials. The nanoscale provides new opportunities to investigate the properties of these materials, e.g., nanoscale hardening and surface reactivity. Metal borides are often considered stable solids because of their covalent character, but little is known on their behavior under a reactive atmosphere, especially reductive gases. We use molten salt synthesis at 750 °C to provide cobalt monoboride (CoB) nanocrystals embedded in an amorphous layer of cobalt(II) and partially oxidized boron as a model platform to study morphological, chemical, and structural evolutions of the boride and the superficial layer exposed to argon, dihydrogen (H2), and a mixture of H2 and carbon dioxide (CO2) through a multiscale in situ approach: environmental transmission electron microscopy, synchrotron-based near-ambient-pressure X-ray photoelectron spectroscopy, and near-edge X-ray absorption spectroscopy...

Ascites is a major complication of cirrhosis. There are several evidence-based articles and guidelines for the management of adults, but few data have been published in relation to children. In the case of pediatric patients with cirrhotic ascites (PPCA), the following questions are raised: How are the clinical assessment and ancillary tests performed? When is ascites considered refractory? How is it treated? Should fresh plasma and platelets be infused before abdominal paracentesis to prevent bleeding? What are the hospitalization criteria? What are the indicated treatments? What complications can patients develop? When and how should hyponatremia be treated? What are the diagnostic criteria for spontaneous bacterial peritonitis? How is it treated? What is hepatorenal syndrome? How is it treated? When should albumin be infused? When should fluid intake be restricted? The recommendations made here are based on pathophysiology and suggest the preferred approach to its diagnostic and therapeutic aspects, and preventive care...

The majority of cancer-associated mortality results from the ability of tumour cells to metastasise leading to multifunctional organ failure and death. Disseminated tumour cells in the blood circulation are faced with major challenges such as rheological shear stresses and cell-mediated cytotoxicity mediated by natural killer cells. Nevertheless, circulating tumour cells with metastatic ability appear equipped to exploit host cells to aid their survival. Despite the long interest in targeting tumour-associated host cells such as platelets for cancer treatment, the clinical benefit of this strategy is still under question...

OBJECTIVES: Feeding difficulties are frequent in children with neurological impairments and can be associated with undernutrition, growth failure, micronutrients deficiencies, osteopenia, and nutritional comorbidities. Gastrointestinal problems including gastroesophageal reflux disease, constipation, and dysphagia are also frequent in this population and affect quality of life and nutritional status. There is currently a lack of a systematic approach to the care of these patients. With this report, European Society of Gastroenterology, Hepatology and Nutrition aims to develop uniform guidelines for the management of the gastroenterological and nutritional problems in children with neurological impairment...
