Fingerprint Raman spectroscopy for two-dimensional MoSSealloys.

Two-dimensional transition metal dichalcogenides (TMDs) and alloys based on them, is a promising platform for creating opto- and nanoelectronic devices. For layered alloys, there is a strong need to theoretically determine the frequencies of vibrational modes and dependences of their energies on the stoichiometric composition. By comparing experimentally measured Raman modes with theoretical predictions, it becomes possible to determine the stoichiometric composition of the manufactured alloys.

The incidence of iron deficiency anemia post-Roux-en-Y gastric bypass and sleeve gastrectomy: a systematic review.

Setting: The physiological and anatomical changes that occur as a consequence of bariatric surgery result in macro- and micro-nutritional deficiencies, especially iron deficiency. The reported incidence of iron deficiency and associated anemia after bariatric surgery varies widely across studies.

Objectives: The aim of this systematic review is to quantify the impact of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) on the incidence of iron deficiency.

Elevated pre-activation basal level of nuclear NF-κB in native macrophages accelerates LPS-induced translocation of cytosolic NF-κB into the cell nucleus.

Signaling via Toll-like receptor 4 (TLR4) in macrophages constitutes an essential part of the innate immune response to bacterial infections. Detailed and quantified descriptions of TLR4 signal transduction would help to understand and exploit the first-line response of innate immune defense. To date, most mathematical modelling studies were performed on transformed cell lines.

[Psychological resources of coping with somatic illness in adolescents].

Objective: Introduction: Somatic illness, objectively and subjectively, can become a difficult life situation for a person. The adolescent's experience of illness is determined by the specifics of a particular age period. To develop an effective rehabilitation program, it is necessary to study the personal characteristics of the adolescent and his social environment, which may be resourceful.

The differences in immunoadjuvant mechanisms of TLR3 and TLR4 agonists on the level of antigen-presenting cells during immunization with recombinant adenovirus vector.

Background: Agonists of TLR3 and TLR4 are effective immunoadjuvants for different types of vaccines. The mechanisms of their immunostimulatory action differ significantly; these differences are particularly critical for immunization with non-replicating adenovirus vectors (rAds) based vaccines. Unlike traditional vaccines, rAd based vaccines are not designed to capture vaccine antigens from the external environment by antigen presenting cells (APCs), but rather they are targeted to the de novo synthesis of vaccine antigens in APCs transfected with rAd.

A scoping review of assessment tools for laparoscopic suturing.

Background: A needs assessment identified a gap in teaching and assessment of laparoscopic suturing (LS) skills. The purpose of this review is to identify assessment tools that were used to assess LS skills, to evaluate validity evidence available, and to provide guidance for selecting the right assessment tool for specific assessment conditions.

Methods: Bibliographic databases were searched till April 2017.

Synthetic peptide TEKKRRETVEREKE derived from ezrin induces differentiation of NIH/3T3 fibroblasts.

Synthetic 14 AA peptide (Gepon) derived from the hinge region of ezrin, a protein that links cell surface molecules to intracellular actin filaments, accelerates and facilitates wound and ulcer healing in clinical applications. However, the molecular mechanisms underlying this phenomenon and involved in enhanced healing of wounds with Gepon are not yet understood. The purpose of current study was to investigate intracellular signaling pathways involved in the effect of this peptide on wild type and genetically modified (CD44 KO) NIH/3T3 embryonic mouse fibroblasts.

Draft Genome Sequence of a Multidrug-Resistant Nosocomial Strain That Persisted in a Hospital in Kemerovo, Russian Federation.

is a frequent cause of health care-associated infections and has led to multiple outbreaks. Here, we report the draft genome of a multidrug-resistant strain 189 which was isolated in 2012 as a predominant clone in a neonatal hospital in Kemerovo.

A systematic review of performance assessment tools for laparoscopic cholecystectomy.

Background: Multiple tools are available to assess clinical performance of laparoscopic cholecystectomy (LC), but there are no guidelines on how best to implement and interpret them in educational settings. The purpose of this systematic review was to identify and critically appraise LC assessment tools and their measurement properties, in order to make recommendations for their implementation in surgical training.

Methods: A systematic search (1989-2013) was conducted in MEDLINE, Embase, Scopus, Cochrane, and grey literature sources.

You have a message! Social networking as a motivator for FLS training.

Objectives: Despite evidence supporting the value of the Fundamentals of Laparoscopic Surgery (FLS) curriculum, surgical educators still find it challenging to motivate residents to practice. Wiggio is an online networking and collaboration tool that allows learners to track performance, see what their peers are doing, and send and receive updates. The purpose of this study was to assess whether using Wiggio increases practice and improves performance of the FLS manual skills.

On association between cortical 5-HT2A receptors and behavior in rats with experimental thyroid disturbances.

Thyroid hormones (TH) were hypothesized to affect behavior via neurotransmission alterations. The present study was aimed to reveal effects of chronic TH deficit and excess on some types of adaptive behavior (catalepsy, acoustic startle reflex, open-field performance), sexual arousal and cerebral 5-HT2A serotonin receptors of adult Wistar rats. Administration of thyroxine synthesis inhibitor, propylthiouracil (PTU, 50 mg/l, 28 days), in drinking water produced substantial decrease in plasma thyroxine level and body weight gain, attenuated significantly acoustic startle reflex amplitude, sexual motivation and plasma testosterone surge in response to receptive female introduction, increased predisposition to catalepsy without considerable effects on open-field performance.
