Ultradeformable archaeosomes (UDA) are nanovesicles made of total polar archaeolipids (TPA) from the archaea Halorubrum tebenquichense, soybean phosphatidylcholine and sodium cholate (3:3:1w/w). Fresh dispersions of UDA including different type of antigens are acknowledged as efficient topical vaccination agents. UDA dispersions however, if manufactured for pharmaceutical use, have to maintain colloidal stability upon liposomicidal processes such as sterilization and lyophilization (SLRUDA), needed to extend shelf life during storage...

Aqueous biphasic systems were investigated for the production of formate-amine-adducts via metal-catalyzed CO2-hydrogenation. Different hydrophobic organic solvents and ionic liquids could be employed as the stationary phase for cis-Ru(dppm)2Cl2 as prototypical catalyst without any modification or tagging of the complex. The solvent pair methyl-isobutylcarbinol (MIBC) and water led to the most practical and productive system and repetitive use of the catalyst phase was demonstrated achieving high endurance with a total TON 150...

Prospective studies describing and predicting individual differences in the course of posttraumatic stress symptoms (PTSS) after disasters are scarce. The present study aimed to describe and predict individual differences in both the level and the rate of change in PTSS after the 2011 Oslo bombing, a terrorist attack directed at the Norwegian government. Survey data from ministerial employees (N = 256) were collected 10, 22, and 34 months after the bombing. We used latent growth modeling to examine the development of PTSS, and to identify the strength of predictor variables...

BACKGROUND: This study addresses whether a unitary cardiac autonomic nervous system index (ANSI), obtained combining multiple metrics from Heart Rate Variability (HRV) into a radar plot could provide an easy appreciation of autonomic performance in a clinical setting. MATERIALS AND METHODS: Data are standardized using percentile ranking of autonomic proxies from a relatively large reference population (n= 1593, age 39±13 years). Autonomic indices are obtained from autoregressive spectral analysis of (ECG derived) HRV at rest and during standing up...

Preschool education is now firmly linked to two aspirational purposes: as the first step on a trajectory of academic and life success for all children and as wise economic policy for the nation. Both purposes are grounded in an assumption that the early developmental boost children receive from preschool will produce lasting impacts. However, efforts to identify enduring impacts of contemporary preschool programs have produced mixed evidence, leading the field to acknowledge that we have yet to adequately understand the essential conditions and processes in early education classrooms that increase the odds that children will flourish in school and thrive in their adult lives...

PURPOSE: Patients with advanced cancer frequently experience anxiety, depression and poor quality of life (QOL), as well as physical symptoms such as fatigue and weakness. Physical exercise has potential to help control these symptoms but the optimal training prescription is still not clear. We performed a study comparing medical Qigong (QG) and standard endurance and strength training (SET) in patients with advanced stage non-small cell lung (NSCLC) and gastrointestinal (GI) cancers...

Millennia of continuous innovation have driven ever increasing efficiency in the milling process. Mechanically characterizing wheat grains and discerning the structure and function of the wheat bran layers can contribute to continuing innovation. We present novel shear force and puncture force testing regimes to characterize different wheat grain cultivars. The forces endured by wheat grains during the milling process can be quantified, enabling us to measure the impact of commonly applied grain pretreatments, such as microwave heating, extended tempering, enzyme and hormone treatments on grains of different 'hardness'...

BACKGROUND: Postexercise nutrition is paramount to the restoration of muscle energy stores by providing carbohydrate and fat as precursors of glycogen and intramyocellular lipid (IMCL) synthesis. Compared with glucose, fructose ingestion results in lower postprandial glucose and higher lactate and triglyceride concentrations. We hypothesized that these differences in substrate concentration would be associated with a different partition of energy stored as IMCLs or glycogen postexercise...

Monitoring surface electromyographic (EMG) signals can provide useful insights for characterizing muscle fatigue, which is defined as an exercise-induced strength loss. This experiment investigated the muscle fiber conduction velocity (CV) changes induced by an endurance run. The day before and immediately after a half-marathon run (21.097 km) 11 amateur runners performed maximum voluntary contractions (MVCs) of knee extensor muscles. During the MVC, multichannel EMG was recorded from the vastus lateralis and EMG amplitude and CV were calculated...

The relationship between students' school environment and exercise habits is complex, and is affected by numerous factors. However, the few studies that have been conducted on this relationship have reported inconsistent results, especially regarding Taiwanese students. We conducted this cross-sectional study to investigate the association of school environment and after-school physical activity with health-related physical fitness in Taiwanese adolescents. Data were drawn from a national survey conducted by the Ministry of Education in Taiwan in 2008 of health-related physical fitness measurements among junior high school students (649,442 total) in grades seven to nine...

Joseph M Santin, Lynn K Hartzler
Semiaquatic frogs may not breathe air for several months because they overwinter in ice-covered ponds. In contrast to many vertebrates that experience decreased motor performance after inactivity, respiratory motor function in bullfrogs, Lithobates catesbeianus, remains functional following cold-submergence. Unlike mammalian hibernators with unloaded limb muscles and inactive locomotor systems, respiratory mechanics of frogs counterintuitively allow for ventilatory maneuvers when submerged. Thus we hypothesized that bullfrogs generate respiratory motor patterns during cold-submergence to avoid disuse and preserve motor performance...

INTRODUCTION: Patients undergoing coronary artery bypass graft surgery often experience a range of symptoms. Studies indicate that non-pharmacological interventions such as exercise training and psychoeducation have a positive physiological and psychological effect in early outpatient rehabilitation. The SheppHeartCABG trial will investigate the effect of early comprehensive rehabilitation in early phase rehabilitation versus usual care. The aim of this paper is to present the protocol for the SheppHeartCABG trial...

BACKGROUND: First-episode psychosis most often has its onset during late adolescence. In caring for the young person, families endure high levels of stress and depression. Meanwhile, the social networks of families often erode. Our group has previously shown that family cognitive behaviour therapy (CBT) leads to significantly improved perceived stress compared with specialist first-episode treatment as usual; however, there are well-known barriers to the dissemination of effective family interventions...

Luigi La Barbera, Tomaso Villa
Mechanical reliability tests on posterior spine stabilization devices are based on standard F1717 by the American Society for Testing and Materials, which describes how to assemble the implant with vertebrae-like test blocks in a corpectomy model. A recent study proposed to revise the standard to describe the anatomical worst-case scenario, instead of the average one currently implemented, and introduce the unsupported screw length as a mechanical parameter. This article investigates the implications of such revisions on the endurance properties of an implant already on the market...

Cross-country skiing is one of the most demanding of endurance sports, involving protracted competitions on varying terrain employing a variety of skiing techniques that require upper- and/or lower-body work to different extents. Through more effective training and extensive improvements in equipment and track preparation, the speed of cross-country ski races has increased more than that of any other winter Olympic sport and, in addition, new types of racing events have been introduced. To a certain extent this has altered the optimal physiological capacity required to win and the training routines of successful skiers have evolved accordingly...
