PURPOSE: Anastomotic or "stitch hole" bleeding is common during vascular surgery with synthetic material such as Dacron or polytetrafluoroethylene (PTFE). Hemostatic adjuncts such as fibrin sealant (FS) may reduce blood loss and operating time in such circumstances. We evaluated the safety and the hemostatic effectiveness of a ready-to-use human plasma-derived FS in vascular surgery. METHODS: Patients with mild / moderate suture line bleeding during elective, open, vascular surgery using synthetic grafts or patches were studied...

The ibogaine derivative 18-methoxycoronaridine (18-MC) has been found to decrease self-administration of morphine, nicotine and alcohol in rats after systemic injection. However oral dosing is the preferred route clinically. The current study evaluated the effect of oral 18-MC dosing in rats on alcohol and nicotine self-administration. For the nicotine study, young adult female Sprague-Dawley rats were fitted with IV jugular infusion catheters and trained for nicotine self-administration in 45min. sessions...

Low back pain (LBP) is the world's most disabling condition. Modic changes (MC) are vertebral bone marrow changes adjacent to the endplates as noted on magnetic resonance imaging. The associations of specific MC types and patterns with prolonged, severe LBP and disability remain speculative. This study assessed the relationship of prolonged, severe LBP and back-related disability, with the presence and morphology of lumbar MC in a large cross-sectional population-based study of Southern Chinese.We addressed the topographical and morphological dimensions of MC along with other magnetic resonance imaging phenotypes (eg, disc degeneration and displacement) on the basis of axial T1 and sagittal T2-weighted imaging of L1-S1...

Systemic 18-methoxycoronaridine, an alpha3beta4 nicotinic antagonist, slows the rate of induction of behavioral sensitization to nicotine (Glick et al., 1996; 2011). The primary mechanism of action of 18-MC is believed to be the inhibition of α3β4 nicotinic acetylcholine receptors which are densely expressed in the medial habenula and interpeduncular nucleus (Pace et al., 2004; Glick et al., 2012). Recently, these habenular nicotinic receptors and their multiple roles in nicotine aversion and withdrawal have been increasingly emphasized (Antolin-Fontes et al...

BACKGROUND: Human and financial resources are increasingly bound due to economic pressure and the working hours Act whereby the already restricted further training times are further limited. The industry also has less funding available for sponsorship of conferences and workshops. Against this background the question arises whether a reduction or focusing of the conferences is necessary; therefore, the aim of this survey was to obtain an opinion from members of the German Society of General and Visceral Surgery (DGAV) and possibly to derive a need for action to submit to the board members...

BACKGROUND: Inequalities in cancer research participation are thought to exist with certain groups under-represented in research populations; however, much of the evidence is based on small-scale studies. The aim of this study was to explore data from in-depth interviews with cancer patients and a large national survey to investigate variation in who is asked to participate in research and who takes part. METHODS: Factors associated with research discussion and participation were explored in National Cancer Patient Experience Survey data using multivariate logistic regression and during in-depth interviews with 25 breast cancer patients...

Understanding how neuromuscular factors that are associated with lower extremity injury risk, such as landing kinematics, muscle strength, and flexibility, change as children mature may enhance age-specific recommendations for injury prevention programs. The purpose of this study was to compare these factors in prepubertal, pubertal, and postpubertal male and female athletes. Subjects were classified on maturation stage (prepubertal: 16 males, 15 females, age: 9 ± 1 years; pubertal: 13 males, 12 females, age: 12 ± 3 years; postpubertal: 30 males, 27 females, age: 16 ± 2 years)...

Noribogaine is the long-lived human metabolite of the anti-addictive substance ibogaine. Noribogaine efficaciously reaches the brain with concentrations up to 20 μM after acute therapeutic dose of 40 mg/kg ibogaine in animals. Noribogaine displays atypical opioid-like components in vivo, anti-addictive effects and potent modulatory properties of the tolerance to opiates for which the mode of action remained uncharacterized thus far. Our binding experiments and computational simulations indicate that noribogaine may bind to the orthosteric morphinan binding site of the opioid receptors...

Mineral carbonation (MC) represents a promising alternative for sequestering CO2. In this work, the CO2 sequestration capacity of the available calcium-bearing materials waste concrete and anorthosite tailings is assessed in gas-solid-liquid and gas-solid routes using 18.2% flue CO2 gas. The objective is to screen for a better potential residue and phase route and as the ultimate purpose to develop a cost-effective process. The results indicate the possibility of removing 66% from inlet CO2 using waste concrete for the aqueous route...

PURPOSE: A 2-part biomechanical study was constructed to test the hypothesis that coronal morphology of the thumb metacarpophalangeal joint impacts the assessment of instability in the context of radial collateral ligament (RCL) injury. METHODS: Fourteen cadaveric thumbs were disarticulated at the carpometacarpal joint. Four observers measured the radius of curvature of the metacarpal (MC) heads. In a custom jig, a micrometer was used to measure the RCL length as each thumb was put through a flexion and/or extension arc under a 200 g ulnar deviation load...
