This study describes the reliability of pragmatic combinations of acupuncture points for lateral epicondylalgia (LE) as prescribed by physiotherapists who were experts in acupuncture. Raters (n Z 14; 33e59 years) independently prescribed acupuncture points for 30 simulated human patients with LE who were surveyed via a printed questionnaire. The frequency and cooccurrence of acupuncture points prescribed for patients with lateral epicondylitis were assessed. Absolute agreement and Light’s kappa (k Light ) with 95% confidence interval (CI) were used to quantify the interrater agreement. Raters prescribed 103 unique acupuncture points in different combinations with a median (min emax) of 5 (0e11) acupuncture points. The most prescribed acupuncture point was LI-11 (297 of 420; 71%), and the most common cooccurring acupuncture points were LI-11and LI-4 (160 of 420; 38%). The absolute agreement for prescribing the acupuncture points ranged from 70% (point GB-20) to 0% (points LI-10, SP-6, LI-11, GB-34, LI-12, and LI-4). Point LR-3 showed the highest interrater reliability for prescribing the acupuncture points [k Light Z 0.112, 95% CI Z (0.055e0.194)], whereas point LI-4 showed the lowest reliability [k Light Z À0.003, 95% CI Z (À0.024 to 0.024)]. These findings suggest that pragmatic prescriptions of acupuncture points for LE are unreliable among physiotherapists who are experts in acupuncture. Explicit, high-level evidence-based rules for prescribing and teaching combinations of acupuncture points for LE are warranted.

<P><B>Abstract</B></P> <P>Hydrogen was generated from ammonia borane complex by hydrolysis using cobalt nanocluster catalyst supported on polydopamine functionalized MWCNTs (multi-walled carbon nanotubes). The impregnation-chemical reduction method was used for the preparation of the supported catalyst. The nanocluster catalyst support was formed by in-situ oxidative polymerization of dopamine on the MWCNTs in alkaline solution at room temperature. The structural and physical–chemical properties of the nanocluster catalyst were characterized by FT-IR (Fourier transform infrared spectroscopy), EDX (energy-dispersive X-ray spectroscopy), SEM (scanning electron microscope), XRD (X-ray diffraction) and TEM (transmission electron microscopy). The nanocluster catalyst showed good catalytic activity for the hydrogen generation from aqueous ammonia borane complex. A reusability test to determine the practical usage of the catalyst was also investigated. The result revealed that the catalyst maintained an appreciable catalytic performance and stability in terms of its reusability after three cycle of reuse for the hydrolysis reaction. Also, the activation energy for the hydrolysis of ammonia borane complex was estimated to be 50.41 kJmol<SUP>−1</SUP>, which is lower than the values of some of the reported catalyst. The catalyst can be considered as a promising candidate in developing highly efficient portable hydrogen generation systems such as PEMFC (proton exchange membrane fuel cells).</P> <P><B>Highlights</B></P> <P> <UL> <LI> Co/Pdop-o-MWCNT (Pdop functionalized MWCNT supported cobalt nanocluster) catalyst was synthesized for hydrogen generation. </LI> <LI> It is an active catalyst for hydrogen generation via hydrolysis of ammonia borane. </LI> <LI> It showed good stability in terms of reusability for the hydrogen generation. </LI> </UL> </P>

Background: To create a sterile, non-pyrogenic solution, Sculptra must first be reconstituted with 5 ml sterile water for injection. This reconstitution process has evolved, has become the norm, and has been recommended for use across the globe since it was marketed to the public for aesthetic reasons. The granuloma formation problem of Sculptra Aesthetic is troublesome to some injectors. It can appear anywhere that you injected and is erratic. According to some patients, the inappropriate mixing of Sculptra microparticles with sterile water or the inability of the microparticles to fully dissolve into the solution are to blame for the development of granulomas. Objective: This article aimed to demonstrate a new reconstitution method (with images) for mixing Sculptra with normal saline. Methods: In the new reconstitution method, we attached a 21G sterile needle to a sterile, single-use 5 ml syringe. Thereafter, we withdrew 2.5 ml normal saline into the 5 ml syringe. The 21G sterile needle was then introduced into the stopper of the vial, and we slowly added all normal saline into the vial. The vial was shaken vigorously to ensure the full hydration of the content. After shaking, the physician could then add any volume of normal saline. Results: A homogenous mixture of Sculptra can be achieved using this new reconstitution method. The mixture is ready to use after the immediate reconstitution of Sculptra. Conclusion: This novel reconstitution technique for Sculptra will result in less unpleasant treatment and less foam wastage on the part of the physician.
