INTRODUCTION: Peer teaching is a well-established teaching method in medical education. During the 2012/13 winter term, the Institute of Anatomy and Cell Biology in Ulm, Germany, introduced a longitudinal didactics program ("Train the Tutor": TtT) to train student tutors as near-peer teachers (NPT) in the dissection course (DC). Twenty-three of 38 tutors participated in the programme. Our study describes the educational concept and the NPTs' activities in the dissection course. METHODS: NPTs documented their activities on a daily basis in the form of semi-structured reports...

Ammoniated lignin, prepared through the Mannich reaction of lignin, has more advantages as a slow-release carrier of urea molecules than ammoxidized lignin and lignin. The advantages of the ammoniated lignin include its amine groups added and its high molecular mass kept as similar as that of lignin. Three organic molecules including guaiacyl, 2-hydroxybenzylamine and 5-carbamoylpentanoic acid are monomers respectively in lignin, ammoniated lignin and ammoxidized lignin. We studied the difference between the interactions of lignin, ammoniated lignin and ammoxidized lignin with respect to urea, based on radial distribution functions (RDFs) results from molecular dynamics (MD) simulations...

Tessa Jalink, Tom Farrand, Carmelo Herdes
A critical appraisal of the current strategies for the synthesis of enantiopure drugs is presented, along with a systematic background for the computational design of stereoselective porous polymers. These materials aim to achieve the enantiomeric excess of any chiral drug, avoiding the racemic separation. Particular emphasis is given to link statistical mechanics methods to the description of each one of the experimental stages within the catalyst's synthesis, setting a framework for the fundamental study of the emerging field of molecularly imprinted catalysts...

BACKGROUND: All health workers should take responsibility for infection prevention and control (IPC). Recent reduction in key reported healthcare-associated infections in the UK is impressive, but the determinants of success are unknown. It is imperative to understand how IPC strategies operate as new challenges arise and threats of antimicrobial resistance increase. METHODS: The authors undertook a retrospective, independent evaluation of an action plan to enhance IPC and 'ownership' (individual accountability) for IPC introduced throughout a healthcare organization...

In order to determine the adsorption mechanism of water on the crystal surfaces of the explosive JOB-9003 and the effect of this adsorption on the sensitivity and detonation performance of this explosive, a model of the crystal of JOB-9003 was created in the software package Materials Studio (MS). The adsorption process was simulated, and molecular dynamics simulation was performed with the COMPASS force field in the NPT ensemble to calculate the sensitivity and detonation performance of the explosive. The results show that the maximum trigger bond length decreases whereas the interaction energy of the trigger bond and the cohesive energy density increase after adsorption, indicating that the sensitivity of JOB-9003 decreases...

BACKGROUND: Undescended testis is a common problem, which is prevalent in 3 % of male infants. This study aimed to determine the effect of leaving the deep inguinal ring (DIR) without closure during laparoscopic orchiopexy (LO), with regard to post-operative hernia formation and other outcomes. METHODS: From 2012 to 2014, 63 testicular units were managed with laparoscopy for non-palpable testis (NPT). Diagnostic laparoscopy was performed for all NPTs, and when they were intra-abdominal (42 testicular units), the DIR was left open after mobilization of the testis into the scrotum medial to the inferior epigastric vessels (Prentiss manoeuvre)...

BACKGROUND: Context is a problem in research on health behaviour change, knowledge translation, practice implementation and health improvement. This is because many intervention and evaluation designs seek to eliminate contextual confounders, when these represent the normal conditions into which interventions must be integrated if they are to be workable in practice. DISCUSSION: We present an ecological model of the ways that participants in implementation and health improvement processes interact with contexts...

TRAIL is a member of the TNF family of cytokines which induces apoptosis of cancer cells via its binding to its cognate receptors, DR5 a high affinity site and DR4 a site of low affinity. Our working group has recently demonstrated that nanovectorization of TRAIL with single wall carbon nanotubes (abbreviated NPT) enhanced TRAIL affinity to the high affinity site DR5 and increased pro apoptotic potential in different human tumor cell lines. In this paper, the DR4 low affinity site was immobilized on a chromatographic support and the effect of temperature on a wide temperature range 1°C-50°C was studied to calculate the thermodynamic parameters of the binding of TRAIL and NPT to DR4 and DR5 receptors...

Difference spectroscopy between two close systems is widely used to augment its selectivity to the different part of the observed system, though the molecular dynamics calculation of tiny difference spectra would be computationally extraordinary demanding by subtraction of two spectra. Therefore, we have proposed an efficient computational algorithm of difference spectra without resorting to the subtraction. The present paper reports our extension of the theoretical method in the isothermal-isobaric (NPT) ensemble...

Treating tinnitus with the resources offered in hospitals can become necessary for patients suffering from complex tinnitus if a high symptom severity, usually accompanied by a corresponding psychosomatic comorbidity, is present. For such costly therapies, for example, the neuro-otologic psychosomatic tinnitus therapy (NPT) examined here, the long-term effect is particularly important; however, reliable catamnesis studies for inpatient treatments are not yet available. Data from 169 (from a total of 327 contacted) inpatients suffering from complex tinnitus were analysed here...

Treatment of bronchial fistula (BF) after pulmonary lobectomy is a challenge. Often, patients require long hospital stay, have recurrent empyema and pneumonia, are susceptible to sepsis, often need broad-spectrum antibiotics, as well as various surgical approaches. With the advent and growing evidence of the benefits of negative pressure therapy (NPT), its use in some patients with BF has been reported with encouraging results concerning its feasibility and cost-effectiveness. The aim of this study was to demonstrate the application of NPT as a resource for BF treatment and comparatively analyze the overall cost of treatment...

INTRODUCTION    Allergic rhinitis (AR) is the most common atopic disease. Specific immunotherapy (SIT) is the only effective treatment method for AR. In uncertain diagnostic cases, before establishing eligibility for SIT, nasal provocation tests (NPTs) should be performed. However, there are numerous contraindications to performing NPTs, and there is ongoing search for an alternative in vitro method. OBJECTIVES    The aim of the study was to determine whether a specific in vitro provocation, that is, the basophil activation test (BAT), may replace a specific in vivo provocation, that is, the NPT, in establishing patient's eligibility for SIT...
