Currently two factors hinder the use of collagen as building block of regenerative devices: the limited mechanical strength in aqueous environment, and potential antigenicity. Polymeric collagen is naturally found in the cross-linked state and is mechanically tougher than the monomeric, acid-soluble collagen ex vivo. The antigenicity of collagen, on the other hand, is mainly ascribed to inter-species variations in amino acid sequences of the non-helical terminal telopeptides. These telopeptides can be removed through enzymatic treatment to produce atelocollagen, although the effect of this cleavage on triple helix organization, amino acidic composition and thermal properties is often disregarded...

Emerging evidence suggests young people at ultra-high risk for psychosis (UHR) are also at-risk for poor physical health, and display high rates of modifiable cardiometabolic risk factors. However, before we can develop effective interventions there is a need to understand factors affecting lifestyle choices in the UHR group. We conducted semi-structured qualitative interviews with 20 UHR individuals (50% male; mean age 21.7), 5 parents (4 mothers, 1 father), and 6 clinicians from early intervention services in the Northwest of England to identify barriers and facilitators to living a healthy lifestyle, including achieving regular exercise, eating well and refraining from excessive substance use...

Adverse effects (AEs) are an important factor in antidepressant treatment decision-making, though common AE profiles from clinical trial research highlight physical AEs to the neglect of emotional and behavioral AEs. First-hand accounts of antidepressant users on the Internet can supplement AE profiles with information gained from real-world treatment experiences. We examined online user reviews of two older (escitalopram; duloxetine) and two newer (vilazodone; vortioxetine) antidepressants for differences in their AE profiles and determined which categories of AEs were associated with users' satisfaction...

In this study, we propose an innovative, bio-based, environmentally friendly approach for the covalent functionalization of multi-walled carbon nanotubes using clove buds. This approach is innovative because we do not use toxic and hazardous acids which are typically used in common carbon nanomaterial functionalization procedures. The MWCNTs are functionalized in one pot using a free radical grafting reaction. The clove-functionalized MWCNTs (CMWCNTs) are then dispersed in distilled water (DI water), producing a highly stable CMWCNT aqueous suspension...

Objective: fall-related injuries constitute major health risks in older individuals, and these risks are projected to increase in parallel with increasing human longevity. Impaired postural stability is a potential risk factor related to falls, although the evidence is inconclusive, partly due to the lack of prospective studies. This study aimed to investigate how objective measures of postural sway predict incident falls. Design, setting and participants: this prospectively observational study included 1,877 community-dwelling individuals aged 70 years who participated in the Healthy Ageing Initiative between June 2012 and December 2015...

Anxiety is a psychological problem that often emerges during the normal course of human life. The detection of anxiety often involves a physical exam and a self-reporting questionnaire. However, these approaches have limitations, as the data might lack reliability and consistency upon application to the same population over time. Furthermore, there might be varying understanding and interpretations of the particular question by the participant, which necessitating the approach of using biomarker-based measurement for stress diagnosis...

Total daily energy expenditure (TEE) and physical activity level (PAL) are important for adequate nutritional management in athletes. The PAL of table tennis has been estimated to about 2.0: it is categorized as a moderate-activity sport (4.0 metabolic equivalents [METs]) in the Compendium of Physical Activities. However, modern table tennis makes high physiological demands. The aims of the present study were to examine (1) TEE and PAL of competitive table tennis players and (2) the physiological demands of various types of table tennis practice...

REVIEW
Hagit Cohen, Zeev Kaplan, Joseph Zohar
Glucocorticoids (GCs) play a major role in orchestrating the complex physiological and behavioral reactions essential for the maintenance of homeostasis. These compounds enable the organism to prepare for, respond to and cope with the acute demands of physical and emotional stressors. The appropriate GC release, commensurate with stressor severity, enables the body to properly contain stress responses so as to promote recovery by rapidly restoring homeostasis. Indeed, inadequate GC release following stress not only delays recovery by disrupting biological homeostasis in the short run but can also interfere with the processing or interpretation of stressful information that results in long-term disruptions in memory integration...

Noam Shohat, Dror Lindner, Iftach Beer, Gabriel Agar
Patellofemoral instability is a complex anatomical phenomena that requires deep understanding. The cause for instability could be a result of an anatomical defect or a soft tissue pathology. A thorough patient history, physical examination and imaging are paramount for a correct diagnosis and for deciding on the correct treatment. The proper treatment is often debatable. Conservative treatment is suitable for acute dislocation but has a high failure rate in chronic instability, which usually necessitates surgical treatment...

Bothersome urinary symptoms during the storage phase are common among women and men. These symptoms described as urinary urgency, frequency and nocturia with or without urge urinary incontinence may be caused by various pathologies including bladder overactivity. Diagnosis of an overactive bladder is based on the patient's clinical presentation after exclusion of other disorders that may cause these symptoms. The minimal requirements for a urological evaluation include medical history, physical examination and urinalysis...

Poor aqueous solubility of anticancer drug, albendazole (ABZ), prevents parenteral application. Here, we demonstrate how to increase the aqueous solubility of ABZ to 6- 8 mg/ml using sulfobutylether - β-cyclodextrin (SBE-β-CD) or Hydroxypropyl- β-cyclodextrin (HP- β-CD) by manipulation of complexation parameters such as the physical state of ABZ (ionized in acetic acid), the concentration of ionised ABZ, agitation time and temperature. Solubility was first examined with suspension of excess ABZ powder in cyclodextrin (CD) solutions at pH (2...

Attachment anxiety is associated with greater perceived physical pain, whereas social support is associated with lower pain perceptions. Few studies, however, have examined the joint effects of attachment and support on acute physical pain in a dyadic context. In this study, first-time expectant mothers (N=140) and their male partners completed romantic attachment measures (prenatally) and postnatal assessments of women's pain and men's emotional support during labor and delivery. More securely attached women benefited from emotional support in terms of reduced pain, more avoidantly attached women reported greater pain when given more support, and more anxiously attached women reported greater pain, regardless of their partner's support...
