Prevalence and determinants of delayed gastric emptying in hospitalised Type 2 diabetic patients

引用

World Journal of Gastroenterology 2008年第10期14卷 1564-1569页

作者： Vladimir Kojecky Jaromir Bernatek Michael Horowitz Stanislav Zemek Jiri Bakala ales Hep Internal clinic of the Postgraduate Medical School Zlin Bata Regional Hospital Zlin 76000 Czech Republic Department of Nuclear medicine Bata Regional Hospital Zlin 76000 Czech Republic Department of Medicine Royal Adelaide Hospital University of Adelaide Adelaide Australia Endoscopy center Masaryk University Hospital Brno Czech Republic

AIM: To determine the prevalence of delayed gastric emptying (GE) in older patients with Type 2 diabetes mellitus. METHODS: One hundred and forty seven patients with Type 2 diabetes, of whom 140 had been hospitalised, mean age 62.3 ± 8.0 years, HbA1c 9.1% ± 1.9%, treated with either oral hypoglycemic drugs or insulin were studied. GE of a solid meal (scintigraphy), autonomic nerve function, upper gastrointestinal symptoms, acute and chronic glycemic control were evaluated. Gastric emptying results were compared to a control range of hospitalised patients who did not have diabetes. RESULTS: Gastric emptying was delayed (T50 > 85 min) in 17.7% patients. Mean gastric emptying was slower in females (T50 72.1 ± 72.1 min vs 56.9 ± 68.1 min, P = 0.02) and in those reporting nausea (112.3 ± 67.3 vs 62.7 ± 70.0 min, P < 0.01) and early satiety (114.0 ± 135.2 vs 61.1 ± 62.6 min, P = 0.02). There was no correlation between GE with age, body weight, duration of diabetes, neuropathy, current glycemia or the total score for upper gastrointestinal symptoms. CONCLUSION: Prolonged GE occurs in about 20% of hospitalised elderly patients with Type 2 diabetes when compared to hospitalised patients who do not have diabetes. Female gender, nausea and early satiety areassociated with higher probability of delayed GE.

The Role of the Matemal Archetype in the Work of Flannery O＇Connor

引用

Journalism and Mass Communication 2016年第11期6卷 700-710页

作者： Natalie ales Brigham Young University Provo USA

This paper explores the motivations behind the behaviors of characters in the work of renowned southern writer, Flannery O＇Connor, and displays that these characters behave the way that they do because of their relationships with their mothers. Herein the author investigates Attachment Theory, a theory regarding the human need to connect with caregivers and nurturers in childhood, and--through a psychological lens--how this principle influences the grown characters in O＇Connor＇s work. In an examination of the prevalent archetype of ＂The Great Mother＂ in her stories, namely ＂The Lame Shall Enter First＂, ＂The Enduring Chill＂, and ＂Parker＇s Back＂, we can see the effects of secure---or confident, warm and reliable--parent-child attachment as well as the effects of insecure---unstable and unreliable--attachment. These different attachment styles contribute to the lifelong development of different behaviors and even personalities in the characters of Norton, Asbury, and O.E. Parker. In the cases above mentioned, the relationship between characters and their maternal figures contribute not only to the plot of the story, but also to the fate of the characters--driving them to do things that are often extreme and climactically catalytic. It proves that parent-child relationships have lasting psychological effects, and, in the case of O＇Connor＇s work, spiritual ones as well. O＇Connor is well known for the religious morals of her works, and in this study it is ultimately evident that the relationships between characters and their maternal figures reflect and influence each character＇s relationship with and attitude towards Deity.

Endogenous Hypoxia in Lateral Root Primordia Controls Root Architecture by Antagonizing Auxin Signaling in Arabidopsis

Molecular Plant 2019年第4期12卷 538-551页

As non-photosynthesizing organs, roots are dependent on diffusion of oxygen from the external environment and, in some in stances, from the shoot for their aerobic metabolism . Establishment of hypoxic niches in the developing tissues of plants has been postulated as a consequence of insufficient diffusion of oxygen to satisfy the demands throughout development. Here, we report that such niches are established at specific stages of lateral root primordia development in Arabidopsis thaliana grown under aerobic conditions. Using gain- and loss-of-function mutants, we show that ERF-Ⅶ transcription factors, which mediate hypoxic responses, control root architecture by acting in cells with a high level of auxin signaling. ERF-Ⅶs repress the expression of the auxin-induced genes LBD16, LBD18, and PUCHI, which are essential for lateral root development, by binding to their promoters. Our results support a model in which the establishment of hypoxic n iches in the developing lateral root primordia con tributes to the shutting down of key auxin-induced genes and regulates the production of lateral roots.

Quality Assurance of Bread and Bakery Pastries in Public Institutions According to the Law on Public Procurement

引用

Journal of Life Sciences 2017年第6期11卷 296-303页

作者： Ana Repse ales Krulec Kindergarten of Ljubljana (VrtecPod Gradom) Praprotnikova 2 Ljubljana 1000 Slovenia lnstitut of Public and Environmentalh Health Zaloska cesta 155 Ljubljana 1000 Slovenia

Public institutions, such as kindergartens, are committed to ordering food according to the Slovenian Law on public procurement （ZJN-3）, which is compliant with EU legislation. There are many bread manufacturers in the market, therefore contracting authority has the challenging task to provide a diverse and high-quality bread and bakery pastries through the process of public procurement. Each buyer has the option of ordering food through the so-called ＂short chain＂, which allows the ordering of locally produced cereals, bread from the organic and integrated production. The Ministry of Health of the Republic of Slovenia issued a ＂Guide to Quality Standards of Food in Public Ordering for Educational Institutions＂ which supports the ordering process. In addition to quality requirements, the buyer divides the tender documentation into several groups and subgroups （e.g. Bread, Bakery pastries and Bread of organic production）. The bakery industry is aware that in kindergartens high-quality bread and bakery pastries are required, therefore they already offer products with reduced salt, sugars, fats, products without trans-fatty acids and gluten. Taking into account the appropriate purchasing specifications and good knowledge of legislation, with respect to public procurement law-related orders, children in kindergartens can be provided with high-quality bread and bakery pastries.

Newtonian Quantum Gravity

引用

Journal of High Energy Physics, Gravitation and Cosmology 2017年第4期3卷 715-726页

作者： Jorge Gabriel ales Corona National Distance Education University of Spain (UNED) Madrid Spain

The quantum treatment of gravity has been researched for more than fifty years. The focus of the efforts was the investigation of the “gravitational quantum field” concept. This article paves the way to solving this puzzle. Gravity is a phenomenon that emerges from the undulating nature of the universe. To support this claim, I deduce a more generalized expression than that of Newton’s gravity from simple considerations relating to the wave function, the probability density function, and a hypothesis of how all particles in the universe are related. This expression uncovers the true nature of the gravitational phenomenon, dark matter, and dark energy. This true nature of the gravitational field allows its renormalization and the definition of its elementary charge. The result obtained considers the Mach’s principle and deduces the origin of the inertial force. Finally, it is concluded that a new model of the universe is necessary.

Temperature Dependence of Sensitivity of Avalanche Photodiode Based Optical Receiver

Temperature Dependence of Sensitivity of Avalanche Photodiod...

引用

2006 10th International Conference on Communication Technology（ICCT 2006）

作者： ales Prokes Institute of Radio Electronics Brno University of Technology Brno Czech Republic

In the paper, the temperature dependence of the sensitivity of an avalanche-photodiode-based receiver applied in the free space optical communication link is discussed. Communication systems of this type are exposed to a wide range of operating temperatures, which markedly affect many photodiode and preamplifier parameters. The paper describes receiver sensitivity calculation, taking into consideration the temperature dependence of avalanche photodiode gain, excess noise factor, dark current and thermal noise of preamplifier resistances. Presented calculation is demonstrated on the connection of a small-area silicon APD operating in the wavelength range from 820 to 1150 nm with a transimpedance preamplifier using a bipolar junction transistor.
