Abstract
The successful development of sheep farming in the meat sector is largely determined by the use of molecular genetic methods and modern genotypes. The Altai Mountain breed of sheep optimally combines high wool and meat with unsurpassed adaptability to grazing in the highlands of the Altai Republic throughout the year. The genes of calpastatin (CAST) and differential growth factor (GDF9) are considered as promising markers of quantitative and qualitative signs of sheep meat productivity. It was established that in the Altai Mountain breed the polymorphism of the CAST and GDF9 genes is represented by three genotypes MM, MN, and NN; AA, AG and GG with a frequency of occurrence of 0.23; 0.72 and 0.05; 0.10; 0.35 and 0.55, respectively. The level of homozygosity (Ca) in the CAST gene was 73.1%, GDF9 – 60.6%. The level of effective alleles (Na) was higher in the GDF9 gene (1.65) compared with CAST (1.44). The level of factual (Ho) and theoretical (He) expected heterozygosity for the GDF9 gene was 0.538 and 0.651, respectively, for the CAST gene – 0.290 and 0.368, which indicates a certain lack of heterozygotes in both genes. The analysis of slaughter qualities established the superiority of carriers of the NN genotype over the MM genotype in the CAS gene in terms of pre-slaughter and carcass weight, meat ratio by 4.96 and 2.83 kg, respectively (P<0.05), 0.26 units (P<0.05). In the GDF9 gene, the AA-type sheep exceeded the peers of AG and GG-genotypes in the pre-slaughter weight, carcass weight and its output, meat ratio by 1.62 and 7.01 kg, respectively; 1.34 and 3.98 kg (P<0.05); 1.21 and 1.86 abs. percent; 0.16 and 0.39 (P<0.05) units.

Abstract
The research objects in the work were natural sources of chondroprotectors. The research purpose was to study perspective natural sources of substances with chondroprotective properties. Such natural chondroprotectors as nutraceutical products made from green tea are studied in the work. Turmeric and ginger have been used since ancient times to treat osteoarthrosis. It has been established that collagen is a part of combined chondroprotectors. The mass fraction of structural protein in various tissues and organs of a living organism varies to a large extent. In pig skin the mass fraction of structural protein reaches 64%, in human skin the content of collagen is 8% higher, in cattle skin 80%, in marine mammals more than 80%; a significant amount of collagen is found in the skin of fish. In the connective tissue of whale fat, up to 88% of collagen is contained, in whale fins up to 83%. The percentage of collagen-containing raw fish is as follows: skin up to 12.6% (of the total weight of the fish); fins up to 8%, air bladder up to 11.4%, scales to 6%, bones up to 19%, sturgeon chord up to 10.2%. Glucosamine, extracted from mollusk shells, chondroitin from shark and bovine cartilage, and collagen hydrolysates are widely used since they are the main components of cartilage matrix. The novelty of this work lies in the systematization of scientific data on perspective natural sources of substances with chondroprotective and combined properties.

Abstract
Fruit and berry sauces are an important and valuable component of nutrition due to sugars, organic acids and biologically active substances. Sauce recipe development should include methods of pre-processing of berries to provide the highest yield of puree while preserving the valuable components of fresh berries. The study focuses on effective methods for processing cornel berries to obtain the maximum yield of puree with high physical and chemical properties. It is shown that the yield of puree can be increased through maximum disruption of the cell cytoplasmic membrane before pulping raw materials that can be attained by blanching (short-term action of steam or hot water for 5–15 minutes), freezing, and microwave treatment. Fresh, ripe, pure, odorless, and mold-free cornel berries of the same pomological variety were taken to conduct the study. The berries pre-sorted and prepared were subjected to freezing, steam and hot water blanching, and microwave treatment at three power modes of the microwave oven. The processed mass of cornel berries was pulped to determine the content of solids, vitamin C, and pH value. It was found that the highest yield of puree (77.5%) from cornel berries is attained through microwave treatment at 350 W. Freezing and steam blanching provide the puree yield of 71.5 and 69.3%, respectively. However, freezing of berry raw materials is accompanied by losses during defrosting. Hot water blanching reduces the amount of soluble solids, which is confirmed by the values of physical and chemical properties of cornel puree.

Abstract
Today energy industry is a fundamental sector of the world economy as it is an energy component that industrialization and digitalization processes of modern society depends on. Economical activities require the following energy properties: reliability, efficiency, non-stop consumer supply. Each year, to implement these requirements becomes more difficult, since dramatic transition from the available energy supply systems to different and innovative ones is taking place in the energy supply sector. In addition, the problem of improving energy-saving technologies becomes the priority in the agro-industrial complex (APK). This article considers the issue of improving energy-saving technologies in irradiation units of greenhouse complexes due to the optimization of reactive power compensation modes using predictive algorithms for controlling devices of compensation of reactive power under non-stationary modes of non-linear loadings. A compensator control algorithm is proposed based on the correlation analysis of energy processes.

Published: December 2020

Abstract
In this study, the first time a 2d finite element models of the titanium dental implant with Ti–Zr or Ti–Nb coating sprayed by electro explosive method and bone tissue located near were constructed. The present models simulate small surface implant section and bone located near. Three models with or without bioinert coating were studied in two configurations with cortical or cancellous bone tissue. All materials used in this study were assumed to be linearly elastic, homogenous, and isotropic to simplify the calculation. The stress distribution in the implant and bone tissue located near is uniform. The largest von Mises stress was obtained near the bone-implant interface in the implant area. It has shown that the stress pattern changed in the models with bioinert coatings. The second stress maximum appeared on the boundary between titanium subtract and the coating layer. The most significant changes in stress distribution were reached in the model with Ti–Zr coating. The electro explosive bioinert coatings help to reduce the stress shielding effect and implant failure probability because of bone strength loss. It also was found shear stress changes in the bone tissue.
Effect of doping Al on the microstructure of Cu-Ni-NiFe2O4-NiO cermets
Authors: Tao Yu-Qiang , Feng Jun-Jun , Chen Yu-Long 
Published: December 2020

Abstract
Cu-Ni-NiFe2O4-NiO cermets doped with Al (0, 0.8, 2, 3.2 wt% ) were prepared by a powder metallurgy process. The effect of Al content, Al adding method and sintering temperature on the microstructure of the cermets were studied using XRD, SEM/EDS, and DSC. The results show that NiO and NiFe2O4 phase are partly reduced to Ni by adding Al at the sintering temperature. The Al element is mainly distributed in the NiFe2O4 phase, and the doping of Al is not conducive to the densification of cermet. The density of the cermet decreases with increasing Al content. The morphology of the metallic phase is related to the Al adding method. Specimens prepared by pre-alloying of Al show smaller metallic particle size than that by mixing of Al. However, the Al adding methods have little effect on the densification and the phase composition. The sintering temperature around the solid phase line of the metallic phase is beneficial to the densification.

Authors: Kane Michael P , Triplitt Curtis L , Solis-Herrera Carolina D 
Published: December 2020

AbstractPurposeTo provide pharmacists with information on counseling patients with type 2 diabetes (T2D) receiving oral semaglutide.SummaryOral semaglutide, the first oral glucagon-like peptide 1 (GLP-1) receptor agonist (GLP-1RA), was approved for the treatment of adults with T2D by the US Food and Drug Administration in September 2019. Semaglutide has been coformulated with the absorption enhancer sodium N-(8-[2-hydroxybenzoyl] amino) caprylate to improve bioavailability of semaglutide following oral administration. Oral semaglutide has been shown to have efficacy and safety profiles similar to those of other GLP-1RAs. Many patients with T2D have a complex oral medication regimen to manage their T2D and concomitant chronic comorbid conditions. Therefore, it is important that patients follow the dose administration instructions closely: oral semaglutide should be taken on an empty stomach upon waking with a sip (≤120 mL) of plain water and at least 30 minutes before the first food, beverage, or other oral medications of the day. The most common adverse effects of oral semaglutide are gastrointestinal (typically nausea, diarrhea, and vomiting). It is important for pharmacists to counsel patients prescribed oral semaglutide about optimal oral dosing, why correct dosing conditions are necessary, expected therapeutic response, and effective strategies to mitigate potential gastrointestinal adverse events.ConclusionInformation and practical strategies provided by pharmacists may facilitate initiation and maintenance of oral semaglutide therapy and ensure that each patient achieves an optimal therapeutic response.

Published: December 2020

Abstract

Background
On March 11, 2020, the World Health Organization declared the novel Coronavirus-19 (COVID-19) a worldwide pandemic, resulting in an unprecedented shift in the Canadian healthcare system, where protection of an already overloaded system became a priority; all elective surgeries and non-essential activities were ceased. With the impact being less than predicted, on May 26, 2020, elective surgeries and non-essential activities were permitted to resume.

Objectives
The authors sought to examine outcomes following elective aesthetic surgery and the impact on the Canadian healthcare system with the resumption of these services during the COVID-19 worldwide pandemic.

Methods
Data were collected in a prospective manner on consecutive patients who underwent elective plastic surgery procedures in 6 accredited ambulatory surgery facilities. Data included patient demographics, procedural characteristics, COVID-19 polymerase chain reaction (PCR) test status, airway management, and postoperative outcomes.

Results
A total of 368 patients underwent elective surgical procedures requiring a general anesthetic. All 368 patients who underwent surgery were negative on pre-visit screening. A COVID-19 PCR test was completed by 352 patients (95.7%) and all were negative. In the postoperative period, 7 patients (1.9%) had complications, 3 patients (0.8%) required a hospital visit, and 1 patient (0.3%) required hospital admission. No patients or healthcare providers developed COVID-19 symptoms or had a positive test for COVID-19 within 30 days of surgery.

Conclusions
With appropriate screening and safety precautions, elective aesthetic plastic surgery can be performed in a manner that is safe for patients and healthcare providers and with a very low risk for accelerating virus transmission within the community.

AbstractWe studied 2351 participants with coronavirus disease 2019; 1177 (50%) reported previous dengue infection. Those without previous dengue had a higher risk of death (hazard ratio: .44; 95% confidence interval: .22–.89; P = .023) in 60-day follow-up. These findings raise the possibility that dengue might induce immunological protection against severe acute respiratory syndrome coronavirus 2.

Abstract
Formaldehyde is present in hair straightening products even when labeled as formaldehyde-free. Inhaled absorption of formaldehyde causes renal tubular cytotoxicity. We report a teenager who developed severe acute kidney injury requiring renal replacement therapy shortly after exposure to a formaldehyde-‘free’ hair straightening product. Kidney biopsy showed acute tubular necrosis and images compatible with microcalcifications. Kidney function improved while on continuous venous–venous hemodialysis.
A Call Center System based on Expert Systems for the Acquisition of Agricultural Knowledge Transferred from Text-to-Speech in China
Authors: Dong Yuhong , Fu Zetian , Stankovski Stevan , Peng Yaoqi , Li Xinxing 
Published: December 2020

Abstract
There is rich knowledge in expert systems that can be used to solve practical problems, but its promotion and application must rely on information facilities. The application of both computers and the Internet for Chinese farmers are not common, which leads to restrictions on the promotion and application of expert systems in rural areas of China. On the other hand, the existing call centers lack a professional knowledge base and the method of automatically calling the knowledge base in real-time, which makes it difficult to meet the needs of users wanting to obtain knowledge in a timely manner. To address these problems, a call center embedded in an expert system inference algorithm and knowledge base for farmers to obtain agricultural knowledge through mobile phones or fixed-line telephones was established. By studying the event-condition-action-based (ECA-based) database triggering model, remote method invocation-based (RMI-based) communication and iterative dichotomiser 3 algorithm-based (ID3-based) parameter extraction, the cohesion between the call center and the expert system was realized. The agricultural knowledge audio acquisition model was then coupled with the call center and the expert system was constructed, allowing farmers to acquire agricultural knowledge through mobile phones or fixed phones with fast responses. When used for cotton disease diagnosis, it can achieve a high diagnostic success rate (above 75%) when at least three disease symptoms are input into the expert system via the voice call, which provides an effective channel for Chinese farmers to obtain agricultural knowledge. It presents good application prospects in China, where 5G technology is currently developing rapidly.

Abstract

OBJECTIVES
Transcatheter pulmonary valve replacement has become a valid treatment option for right ventricular outflow tract diseases. However, some limitations occur in patients with wide, compliant right ventricular outflow tracts that might be amenable to treatment with self-expanding valved protheses. An experimental ovine study was designed to evaluate a novel dip-coated, low-profile trileaflet polycarbonate urethane (PCU) heart valve mounted into a self-expandable nitinol stent.

METHODS
The PCU valves were produced by a dip-coating technique, mounted in a conical-shaped nitinol stent and provided with a leaflet thickness of 100–150 µm. The valved stents were implanted percutaneously via transfemoral access in 6 consecutive sheep divided into 2 groups. Three animals were followed up for 1 month and the remainder, for 6 months. Angiographic measurements and transthoracic echocardiography were performed before and after implantation and at the end of the 1- or 6-month observation period, respectively.

RESULTS
Orthotopic positioning of the valve was achieved in all animals. All except 1 had competent valves during the follow-up period. The peak-to-peak gradient across the PCU valved stents was 4.6 ± 1.0 mmHg after 1 month and 4.4 ± 2.3 mmHg after 6 months of follow-up. Macroscopic and microscopic post-mortem evaluation indicated good morphological and structural results. There were no stent fractures, leaflet calcification or thrombus formation.

CONCLUSIONS
This study demonstrates successful transcatheter pulmonary valve replacement with a novel dip-coated valved nitinol stent. The trileaflet PCU prostheses indicated good functional and biocompatible properties after a 6-month observation period.

Factors influencing the implementation of the Health Promoting University initiative: experiences of Ibero-American universities
Authors: Suárez-Reyes Mónica , Muñoz Serrano Mónica , Van den Broucke Stephan 
Published: December 2020

SummaryThe Health Promoting University (HPU) concept encourages universities to incorporate health into the university context. HPU initiatives exist worldwide, yet information on how universities translate the HPU concept into actions is scarce. This study aimed to identify the factors influencing the implementation of HPU initiatives in Ibero-American universities. Semi-structured interviews were held with seventeen representatives of universities in Ibero-America that had implemented an HPU initiative. All interviewees had been involved in the initiative and had occupied a position of responsibility for at least 1 year before the study. The interviews were carried out remotely, and the data were analyzed using an inductive approach. The main factors influencing the implementation of an HPU initiative were political support by the university authorities, coordination structure, funding, collaboration inside and outside university and participation of the university community. Among them, political support by the university authorities was considered the most important, although some initiatives succeeded without it and managed to obtain support during the implementation process. This study is one of the first to investigate the factors influencing the implementation of the HPU concept. A better understanding of these factors would enable universities to address them to develop the HPU initiative in the best possible conditions.
