TL;DR: In this article, the relationship between physicochemical properties of the solution against the membrane support layer and ICP was explored by incorporating constrictivity, and four solutions with different diffusivities, ion/molecule sizes and viscosities were systematically investigated using a bench-scale forward osmosis system.

TL;DR: Increased cortisol and reduced sex hormone binding globulin (SHBG) are both consistent with development of insulin resistance, although hepatic insulin resistance calculated from fasting HOMA did not change significantly.
Abstract: Background Sleep restriction is associated with development of metabolic ill-health, and hormonal mechanisms may underlie these effects. The aim of this study was to determine the impact of short term sleep restriction on male health, particularly glucose metabolism, by examining adrenocorticotropic hormone (ACTH), cortisol, glucose, insulin, triglycerides, leptin, testosterone, and sex hormone binding globulin (SHBG). Methodology/principal findings N = 14 healthy men (aged 27.4±3.8, BMI 23.5±2.9) underwent a laboratory-based sleep restriction protocol consisting of 2 baseline nights of 10 h time in bed (TIB) (B1, B2; 22:00-08:00), followed by 5 nights of 4 h TIB (SR1-SR5; 04:00-08:00) and a recovery night of 10 h TIB (R1; 22:00-08:00). Subjects were allowed to move freely inside the laboratory; no strenuous activity was permitted during the study. Food intake was controlled, with subjects consuming an average 2000 kcal/day. Blood was sampled through an indwelling catheter on B1 and SR5, at 09:00 (fasting) and then every 2 hours from 10:00-20:00. On SR5 relative to B1, glucose (F(1,168) = 25.3, p Conclusions/significance Sleep restriction impaired glucose, but improved lipid metabolism. This was associated with an increase in afternoon cortisol, without significant changes in ACTH, suggesting enhanced adrenal reactivity. Increased cortisol and reduced sex hormone binding globulin (SHBG) are both consistent with development of insulin resistance, although hepatic insulin resistance calculated from fasting HOMA did not change significantly. Short term sleep curtailment leads to changes in glucose metabolism and adrenal reactivity, which when experienced repeatedly may increase the risk for type 2 diabetes.

TL;DR: The results of this study suggest that motor control exercises and graded activity have similar effects for patients with chronic nonspecific low back pain.
Abstract: Background. Motor control exercises to improve control and coordination of trunk muscles and graded activity under the principles of cognitive-behavioral therapy are 2 commonly used exercise therapies, yet there is little evidence to support the use of one intervention over the other. Objective. The objective of this study was to compare the effectiveness of motor control exercises and graded activity for patients with chronic nonspecific low back pain. Design. This study was a prospectively registered randomized controlled trial with outcome assessment and statistical analyses conducted blind to group. Setting. The study was conducted in primary care settings. Patients. The participants were 172 patients with chronic (12 weeks) nonspecific low back pain. Interventions. Patients were randomly assigned to receive either motor control exercises or graded activity. There was no attempt to subclassify patients to match them to a treatment. Patients in both groups received 14 sessions of individualized, supervised exercise therapy. Measurements. Primary outcomes were average pain over the previous week (numeric rating scale) and function (Patient-Specific Functional Scale); secondary outcomes were disability (24-item Roland-Morris Disability Questionnaire), global impression of change (Global Perceived Effect Scale), and quality of life (36-Item Short-Form Health Survey questionnaire [SF-36]). Outcome measures were collected at baseline and at 2, 6, and 12 months after intervention. Results. A linear mixed models analysis showed that there were no significant differences between treatment groups at any of the time points for any of the outcomes studied. For example, the effect for pain at 2 months was 0.0 (0.7 to 0.8). Limitations. Clinicians could not be blinded to the interventions. Conclusion. The results of this study suggest that motor control exercises and graded activity have similar effects for patients with chronic nonspecific low back pain.

TL;DR: How nanosystems are being increasingly exploited for topical and cutaneous delivery, particularly for these previously difficult substances is described, which is driven by the development of novel technologies, which include minimally invasive delivery systems and more precise fabrication techniques.
