Studies on the structure and catalytic performance of Cu-Zn-Al catalyst prepared by liquid-phase preparation technology under different heat treatment atmosphere

Cu-Zn-Al slurry catalysts were prepared using a complete liquid-phase preparation technology under different heat treatment atmospheres.The catalysts were characterized using X-ray diffraction,X-ray photoelectron spectroscope,and N2 adsorption-desorption.Their application in the single-step synthesis of dimethyl ether from syngas was also investigated.The results indicate that the type of heat treatment atmosphere has an influence on the Cu species and the Cu0/Cu＋ ratio on the catalyst surface.Moreover,the final Cu/Zn ratio on the catalyst surface is mainly dependent on the composition and reaction environment of the catalyst and less on the type of heat treatment atmosphere.The prepared catalysts can suppress sintering of active sites at high temperatures,and the type of heat treatment atmosphere mainly affects the capability of the catalyst for methanol synthesis.The catalysts perform best using N2 as the heat treatment atmosphere.

A Non-Invasive Skin Treatment Combining LED with Pharmacologic and Ultrasonic Technologies for Facial Rejuvenation

Background: Non-invasive facial treatments have the ability to rejuvenate the facial profile when specific pharmacologic agents and modalities are prescribed and used in combination taking into consideration each patient’s unique skin type and condition. RATIONALE Epinova is a non-invasive skin treatment that combines the correct concentrations and combinations of topicals and modalities to elicit facial rejuvenation with no down-time or side effects. Purpose: This paper focuses on facial rejuvenation improvements combining the RATIONALE Essential Six skincare system (RATIONALE, Victoria, Australia) to protect and repair the skin with the RATIONALE Epinova facial treatment every 4-6 weeks—which uses non-invasive technologies and professional strength active ingredients to deliver visible changes to skin tone and texture. Methods: Subjects underwent a RATIONALE consultation, including taking a skin history and skin imaging, followed by a data analysis and diagnosis of skin condition and prescription of a customized RATIONALE treatement (Epinova), including appropriate pharmacologic agents and treatment with personalized photo/sono therapeutic devices. Results: Subjects reported increased skin hydration, tactile improvements, skin firmness and visible radiance following the RATIONALE Epinova treatment. Further investigations will be initiated to explore the potential for longer term improvements, including connenctive tissue deposition, reduction of erythema etc. Treatments should be performed every 4-6 weeks for patients under 40 and every 3-4 weeks for patients over 40, to support cell differentiation, migration and desquamation to achieve non-invasive facial rejuvenation.

Is appendoscope a new option for the treatment of acute appendicitis?

Acute appendicitis is a common surgical emergency.It is commonly caused by obstruction of the appendiceal lumen due to fecaliths,tumors,or lymphoid hyperplasia.For over a century,appendectomy has been the primary treatment for acute appendicitis.Abraham Groves performed the first open appendectomy in 1883.In 1983,Kurt Semm completed the first laparoscopic appendectomy,heralding a new era in appendectomy.However,appendectomy is associated with certain complications and a rate of negative appendectomies.Studies have suggested controversy over the impact of appendectomy on the development of inflammatory bowel disease and Parkinson’s disease,but an increasing number of studies indicate a possible positive correlation between appendectomy and colorectal cancer,gallstones,and cardiovascular disease.With the recognition that the appendix is not a vestigial organ and the advancement of endoscopic technology,Liu proposed the endoscopic retrograde appendicitis therapy.It is an effective minimally invasive alternative for treating uncomplicated acute appendicitis.Our team has developed an appendoscope with a disposable digital imaging system operated through the biopsy channel of a colonoscope and successfully applied it in the treatment of appendicitis.This article provides an overview of the progress in endoscopic treatment for acute appendicitis and offers a new perspective on the future direction of appendiceal disease treatment.

Cardiac rehabilitation after cardiac surgery:An important underutilized treatment strategy

Physical inactivity remains in high levels after cardiac surgery,reaching up to 50%.Patients present a significant loss of functional capacity,with prominent muscle weakness after cardiac surgery due to anesthesia,surgical incision,duration of cardiopulmonary bypass,and mechanical ventilation that affects their quality of life.These complications,along with pulmonary complications after surgery,lead to extended intensive care unit(ICU)and hospital length of stay and significant mortality rates.Despite the well-known beneficial effects of cardiac rehabilitation,this treatment strategy still remains broadly underutilized in patients after cardiac surgery.Prehabilitation and ICU early mobilization have been both showed to be valid methods to improve exercise tolerance and muscle strength.Early mobilization should be adjusted to each patient’s functional capacity with progressive exercise training,from passive mobilization to more active range of motion and resistance exercises.Cardiopulmonary exercise testing remains the gold standard for exercise capacity assessment and optimal prescription of aerobic exercise intensity.During the last decade,recent advances in healthcare technology have changed cardiac rehabilitation perspectives,leading to the future of cardiac rehabilitation.By incorporating artificial intelligence,simulation,telemedicine and virtual cardiac rehabilitation,cardiac surgery patients may improve adherence and compliance,targeting to reduced hospital readmissions and decreased healthcare costs.

Preliminary study on treatment of waste organic matter from livestock by bacteria-mineral technology

The present study dealt with relationships between the degradation and humification process that the organic matter underwent during bacteria-mineral technology. An inverse correlation was found between the protein, lipid, and some of the humification indices considered, suggesting that the humification theory is actually humic substances produced from simple-structured natural organic substrates. Weight-average molecular weight （Mw）, number-average molecular weight （Mn）, and the ratio Mw/Mn of dissolved organic matters at different stages of the process were measured by gel permeation chromatography. The results showed that Mn and Mw increased with reaction time from 352 to 17,191, and from 78,707 to 104,564, respectively. The ratio of Mn/Mw decreased from 223.3 to 6.1. This reflected the growth of the polymerization degree of dissolvable organic matters in the process; furthermore, it indicated the formation of complex molecules （humic substances） from more simple molecules. Bacteria-mineral water （BMW） （the effluent of the process） treatments can exert hormone-like activity for enhanced seed germination of wheat and rice and greatly improved chlorophyll synthesis in wheat and rice leaves, Major polyamines （plant regulators） putrescine, spermidine, and spermine, were found in BMW by a high performance liquid chromatography （HPLC） method, which may explain the hormone-like activity of BMW.
