After 1 h of release, honeycomb and coaxial annulus tablet gels exhibit higher release rates at approximately 80%. The experimental data is fitted to empirical release kinetic models and the Higuchi model is shown to yield the best fitting results. Overall, by using a novel biocompatible photochemistry and 3D printing we have shown that it is possible to successfully load and release ascorbic acid as a model agent, opening up a new class of manufacturing protocols to encapsulate ascorbic acid and other water-soluble vitamins as well as many different drugs for drug delivery applications.18-α-Glycyrrhetinic acid (GA) is a bioactive compound extracted from licorice that exhibits many biological and pharmacological effects such as anti-inflammatory and antioxidant activities on the skin. However, its lipophilic nature results in poor bioavailability that limits clinical applications. Liposomes, presenting the ability to carry both hydrophobic and hydrophilic payloads and a good cytocompatibility, are effective to overcome this barrier. Furthermore, the addition of permeation enhancers such as ethanol into liposomal formulations helps the diffusion of these systems through the skin barrier. Here, we aimed to formulate GA-loaded ethanolic liposomes, using a natural soybean lecithin via a microfluidic approach. Using a fused deposition modeling (FDM) 3D printer we customized a microfluidic chip, and manufactured vesicles that presented spherical shape with a size of 202 ± 5.2 nm, a narrow size distribution and a good stability over a period of 30 days. After reaching a drug encapsulation efficiency of 63.15 ± 2.2%, liposomes were evaluated for their cytocompatibility and skin permeation potentiality after hydrogelation using xanthan gum. The in vitro release and permeation studies were performed using Franz diffusion cells comparing two different media and three synthetic membranes including a polymeric skin-mimicking membrane. The selected formulation presented no cytotoxicity and an increased permeation compared to GA saturated hydrogel. It could perform therapeutically better effects than conventional formulations containing free GA, as prolonged and controlled release topical dosage forms, which may lead to improved efficiency and better patient compliance.Delirium is a common symptom in patients admitted to our hospital with COVID-19, and in cases of hyperactive delirium we have frequently observed behaviors that pose a significant risk of disease transmission to health care providers. Managing this symptom has emerged as an important challenge, as our local health care system has been strained by providers becoming sick or quarantined. Preventative and non-pharmacologic interventions remain critical for managing delirium in such patients, though occasionally pharmacologic treatment is required. When use of an antipsychotic medication is indicated, we recommend that providers consider foregoing the lowest common dose and instead start with the next incrementally higher dose to more quickly and reliably ensure the safety of both patients and providers. Navitoclax price We do not recommend initiating prophylactic treatment or escalating doses in a manner that conflicts with currently accepted guidelines without carefully considering the risks and benefits.Purpose Soccer match-play is typically contested over 90 min; however, in some cup and tournament scenarios, when matches are tied, they proceed to an additional 30 min, which is termed “extra-time” (ET). This systematic review sought to appraise the literature available on 120-min of soccer-specific exercise, with a view to identifying practical recommendations and future research opportunities. Methods The review was conducted according to the PRISMA guidelines. Independent researchers performed a systematic search of PubMed, CINAHL and Psych Info in May 2019, with the following keywords entered in various combinations “soccer,” “football,” “extra-time,” “extra time,” “120 minutes,” “120 min, “additional 30 minutes,” and “additional 30 min.” Results The search yielded an initial 73 articles. Following the screening process, 11 articles were accepted for analyses. Articles were subsequently organized into the following 5 categories movement demands of extra-time, performance responses to extra-time, physiologic and neuromuscular response during extra-time, nutritional inventions, and recovery and extra-time. The results highlighted that during competitive match-play, players cover 5%-12% less distance relative to match duration (i.e., meters per minute) during ET compared to the preceding 90 min. Reductions in technical performance (i.e., shot speed, number of passes and dribbles) were also observed during ET. Additionally, carbohydrate provision may attenuate and improve dribbling performance during ET. Moreover, objective and subjective measures of recovery may be further compromised following ET when compared to 90 min. Conclusion Additional investigations are warranted to further substantiate these findings and identify interventions to improve performance during ET.Purpose This quasi-experimental study examined the impact of height-adjustable desks in combination with prompts to break up prolonged sitting time during class time and identified social and motivational factors associated with breaking up sitting time among adolescents. Teachers’ perceptions of strategies were also examined. Methods Over 17 weeks, 1 classroom in a government secondary school in Melbourne, Australia, was equipped with 27 height-adjustable desks and prompts (posters and desk stickers) to break up classroom sitting time. Teachers received professional development in the use of the desks and prompts. One group of adolescents (n = 55) had 2-5 lessons/week using the height-adjustable desks in an intervention classroom, and a comparison group matched by year level and subject (n = 50) was taught in traditional “seated” classrooms. Adolescents wore an activPAL monitor at baseline (T0), 4 weeks (T1), and 17 weeks (T2) and completed a survey at T0 and T2. Six teachers participated in interviews at T2. Effect sizes were calculated (d). Results Linear mixed models found that, compared to the traditional “seated” classrooms, the adolescents in the intervention classroom had significantly lower sitting time (T1 -9.7 min/lesson, d = -0.96; T2 -6.7 min/lesson, d = -0.70) and time spent in sitting bouts >15 min (T2 -11 min/lesson, d = -0.62) and had significantly higher standing time (T1 7.3 min/lesson, d = 0.84; T2 5.8 min/lesson, d = 0.91), number of breaks from sitting (T1 1.3 breaks/lesson, d = 0.49; T2 1.8 breaks/lesson, d = 0.67), and stepping time (T1 2.5 min/lesson, d = 0.66). Intervention classroom adolescents reported greater habit strength (d = 0.58), self-efficacy for breaking up sitting time (d = 0.75), and indicated that having a teacher/classmate remind them to stand as helpful (d = 0.50). Conclusion This intervention shows promise for targeting sitting behaviors in the classroom and indicates that incorporating social and motivational strategies may further enhance outcomes.
