Urease, also known as urea amide hydrolase, contains two metal nickel ion active centers that catalyze the decomposition of urea to ammonia and carbon dioxide. Urease is widely found in nature, including plants, animals, and microorganisms, and greatly affects the utilization of nitrogen-containing nutrients by plants and animals. At the same time, its content can also affect the normal physiological metabolism of microorganisms, which in turn affects the survival rate of microorganisms. It can be seen that the role of urease inhibitors is very important. Urease inhibitors, such substances, can affect or even inhibit the activity of urease by direct or indirect means. Guided by computer-aided drug design, the team developed two new urease inhibitors, which are low-cost, non-toxic to plants, animals and humans, and environmentally friendly urease inhibitors. After experimentally measuring the activity of urease inhibitors, the two urease inhibitors have stronger inhibition ability than the widely used acetohydroxamic acid on the market.

Ganoderma lucidum has been a well-known herb since ancient times and has the reputation of “Xiancao”. In modern times, Ganoderma Lucidum is used more in nourishing health products. Chinese medicine believes that Ganoderma lucidum is sweet, flat, and beneficial to qi and blood. It has the effect of soothing the mind, strengthening the spleen and nourishing the stomach. Clinically, it is also often used to treat insomnia, fatigue, and asthma. The Ganoderma lucidum real estate area has changed greatly from ancient to modern. The wild production area has changed from the ancient Wuyue Mountain to the current major lakes and seas. The cultivation of Ganoderma lucidum began in the 1950s, and the production area has changed to today’s Hubei, Hainan and other places. Currently cultivated Ganoderma lucidum. Has become the main body of Ganoderma lucidum. Hubei is an important real estate area. This paper mainly summarizes and analyzes the original plant and growth environment, cultivation techniques, pest control, medicinal properties, chemical composition, pharmacological effects and clinical use of the existing Chinese herbal medicine Ganoderma lucidum. From the research on the origin, traits, growth habits, medicinal properties and clinical application of Ganoderma lucidum, it provides practical information for the cultivation, use and pharmacological properties of Ganoderma lucidum. At the same time, the summary and analysis of Ganoderma lucidum information will be conducive to further research on the efficacy and marketization of Ganoderma lucidum.

Conversational implicature and conversational principle are proposed by the American language philosopher Grice. The principle of conversation is an important part of the study in the field of pragmatics, represented by Grice’s Cooperative principle and Leech’s Politeness principle, which constitutes the main reference principle and basis for understanding the meaning of conversation. To a certain extent, they regulate people’s verbal communication behavior. Grice believes that in the process of people’s communication, the two sides of the dialogue seem to follow a certain principle intentionally or unintentionally in order to complete the communicative task effectively. But sometimes, to make the communication activities go smoothly, the communicative parties usually break the cooperative principles in order to achieve some kind of communicative purpose. Based on the daily communicative dialogue as corpus, this paper analyzes the communicative implicature that violates the principle of conversation. Through the analysis of communicative implicature and pragmatic effect to explore the main forms of conversational implicature in verbal communication in the context of real communication.

With the development of the Internet, the expression of information is not limited to words, but it develops into other modes, such as images, sounds, actions, etc. This study is based on the visual grammar. The visual grammar proposed by Kress and Van Leeuwen is based on Halliday’s systemic functional linguistics. Coca-Cola as a popular soft drink brand, its graphic advertising design can be said to be very mature and representative. This study is based on visual grammar to carry on the thorough analysis to the American Coca-Cola classic print advertisement, carries on the analysis to each print advertisement from the reproduction meaning, the interactive meaning and the composition meaning. The following conclusions can be drawn: 1. In the Coca-Cola print advertisement in the United States, the professional characteristics of the characters are obvious. 2. Advertising language can directly express the benefits of the product. 3. The combination of image mode and language mode in the Coca-Cola print advertisement can be explained by visual grammar.

An individual’s dietary and supplement strategies can influence markedly their physical performance. Issues related to knowledge of nutrition and dietary supplementation (DS) are understudied in professional athletes. Supplements nowadays are used with the aim of improve body composition, of which the origins are multiplex in structure. Many approaches to improve the response to resistance training are the use of pre-/post-/in between workout nutritional interventions; with beverages garnering significant interest. The health benefits and risks of dietary supplement use are controversial as there is no visible immediate benefits observed. Sports nutrition recommendations for endurance exercise however remains a complex issue with often opposing views and advice by various health care professionals. Many athletes, at all levels of competition, place great emphasis on the use of dietary supplements, but of all the factors that determine athletic performance, supplements can play only a very small role. Compared with factors such as talent, training, tactics, and motivation, nutrition has a small effect on performance, and supplements can be no more than a minor part of the athlete’s nutrition strategy.

This paper assessed the Transport and Logistics Education as a University undergraduate programme being offered by some selected universities in Southwestern Nigeria. The specific objectives of this study are to examine the programmes of transport and logistics education with a view to understand areas where they are lagging behind across the selected Universities. Secondly, to determine those attributes that may facilitate qualitative education, not only in transport sector; but also at improving Nigerian universities education system. The total of 250 recently graduating students of the selected universities were randomly sampled and given both questionnaires and assessment form which covers six major subjects in the areas of Logistics and Transport. Descriptive analytical technique was used to achieve the first objective and Principal Component Analysis (PCA) was used to factorize fifteen identified variables and reduced it to eight principal components considered to facilitate qualitative education in Transport and Logistics Education in Nigeria. The results showcased the areas of strength and weaknesses of the selected schools and principal factors that must be available for qualitative logistics and transport education system in Nigeria.

Psychiatric disorders are one of the major causes of global burden of diseases. Stigma remains a major impediment in the delivery of mental healthcare. It has been found across various studies that attitudes of doctors of other specialties and other healthcare professionals also contribute to stigma due to their lack of knowledge and awareness about psychiatry and mental health problems. The number of mental health professionals remains abysmally low. Community pharmacists are accessible, knowledgeable, and capable of providing mental health promotion and care in communities. This may not be a role that is recognized by the public, and men in particular. However, psychotherapy paired with medication is the most effective way to promote recovery. Examples include: Cognitive Behavioral Therapy, Exposure Therapy, Dialectical Behavior Therapy, etc. Pharmacists can play a key role by providing mental health medication management support to improve access and address patients’ mental health needs.

Athletes utilize numerous strategies to reduce body weight or body fat and to increase stamina prior to competition. Personalized nutrition in athletic populations aims to optimize health, body composition, and exercise performance by targeting dietary recommendations to an individual’s genetic profile. Additionally, athletes’ nutritional requirements may vary widely depending on sport, position, timing of season, and training vs rest day. Bodily hydration during sporting activity is one of the best indicators of health in athletes and can be a limiting factor for sport performance. Treatment for athletes is primarily to increase energy availability and often requires a team approach including a sport physician, sports dietitian, physiologist, and psychologist. Maximizing athletic performance is a passion that athletes, coaches, athlete support professionals, and sports scientists share. A thorough understanding of the basics of all aspects of human physiology and the ability of the body to adapt to the environmental stress of exercise training is the foundation we use to explain the incredible athletic and sport performances that are commonplace in today’s world.

Background: Depression is a very important part of global mental health concerns. Many of the studies on correlates of depression stopped short of finding the predictors. Predictive models will empower preventative efforts by healthcare providers and policy makers. The purpose of this study was to determine the factors predicting depressive symptoms among a population of older men and women in rural South Africa. Methods: Data were obtained from “Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) in the INDEPTH Health and Demographic Surveillance System (HDSS) site of Agincourt” in rural Mpumalanga province, South Africa. Previously validated short-version Center for Epidemiologic Studies Depression Scale (CES-D 8) was used to assess for depressive symptoms. Multivariable logistic regression model with stepwise selection, and receiver operating curve were used to examine the predictors of depression. Results: Of the 4027 participants included in this study, 743 (18.5%) met the criterion for depression (CES-D 8 score ≥3). Older age (OR 1.025, CI 1.016-1.034), diabetes (OR 1.467, CI 1.152-1.868), and alcohol consumption (OR 1.536, CI 1.261-1.872) predicted depression. Being male (OR 0.734, CI 0.588-0.915) and homemaker rather than not working (OR 0.513, CI 0.372-0.707) were protective. Compared to those who were married, depressive symptoms were significantly higher among the separated/divorced (OR 1.372, CI 1.027-1.834) and the widowed (OR 1.468, CI 1.172-1.839). Conclusions: It is possible to predict the development of depression in this community, and findings are generalizable to other communities and countries. Healthcare workers and policy makers should use the findings for preventative care and policies.

Scholars note that failing public schools are the civil rights issue of our day (Frankenberg, 2011; Orfield, 2004). The current discussion about school reform in the U.S. over the past two decades has shifted from one of equity to one based on excellence in the form of student achievement. A primary solution for student achievement has been popularized and made into dominant discourse through legislation such as No Child Left Behind (2001) and Race to the Top (2009). In this analysis, the author provides a historical context of the charter school movement as a backdrop for charter school enrollment trends and policy in Georgia. As charter schools in Georgia continue to gain popularity as a primary school choice option for African American students, it is essential that policymakers create charter legislation that encourages the creation of socioeconomically and racially diverse schools. Moreover, both policymakers and stakeholders in education need to decide to what end are we expanding choice, and what kinds of choice might get us closer to more integrated, and ultimately, democratic schools?
