The Use of Glycated Albumin in the Diagnosis of Gestational Diabetes Mellitus

Journal of Biosciences and Medicines 2024年第1期12卷 19-28页

作者： Atochi Prince Woruka Celestine Osita john Obstetrics and Gynecology Department University of Port Harcourt Teaching Hospital Port Harcourt Nigeria Obstetrics and Gynecology Department University of Port Harcourt Port Harcourt Nigeria

Gestational diabetes mellitus is the most common endocrine disorder in pregnancy and a cause of maternal and fetal morbidities and mortalities. The oral glucose tolerance test is the gold standard for diagnosing gestational diabetes mellitus. Nevertheless, the oral glucose tolerance test is time-consuming and requires patient preparation. On the contrary, Glycated albumin does not require patient preparation or administration of any substance. Most studies on glycated albumin in pregnancy were among the non-African population, and black Americans have higher glycated albumin levels than Caucasians. This study determined the use of glycated albumin in diagnosing gestational diabetes mellitus among pregnant women. The study was a prospective study of 160 pregnant women between 24 and 28 weeks of gestation at the University of Port Harcourt Teaching Hospital. The diagnosis of gestational diabetes mellitus was based on the World Health Organization 2013 criteria. The diagnostic value of glycated albumin was determined using the area under the receiver operator characteristic curve. The prevalence of gestational diabetes mellitus was 9.4% and the mean glycated albumin was 16.91% (±2.77). The area under the receiver operator characteristic curve for glycated albumin was 0.845 (95% CI 0.733 - 0.956;p = 0.0001). The optimal cut-off value of glycated albumin in the diagnosis of gestational diabetes mellitus was 18.9%. Glycated albumin was useful in the diagnosis of gestational diabetes mellitus at 24 to 28 weeks of gestation.

World Journal of Cardiovascular Diseases 2024年第9期14卷 588-602页

作者： Lamwaka Alice Veronica Mboowa john Bosco Department of Pharmacy Faculty of Medicine Gulu University Gulu City Uganda

Hypertension is a big problem worldwide. The purpose of this study is to examine the prevalence, knowledge, attitude, and practice about hypertension at Gulu University, Gulu city, Gulu district, Acholi subregion, Northern Uganda. A literature search on hypertension was done. It showed that, in Uganda, a representative number of 17,777 adult patients’ data were analyzed from January 2014 to February 2024. The epidemiological data on awareness of hypertension was found to be at 8%. Of this, 18.3% of the people with hypertension had it under control. The results of the findings were promising. Hypertension is an important public health challenge in Uganda particularly in Northern Uganda where Gulu University falls. In comparison with the two regions of Central Uganda and Northern Uganda, there was a significant number of populations that were not aware of their condition. Those diagnosed were on treatment but the treatment was not adhered to due to stock outs of medicines. Therefore, Measures are required to prevent hypertension, improve awareness, treatment and control within the community, especially at Gulu University where research has never been done.

作者： john Joseph Tedesco Gerald Thomas Tedesco Harvard Universitys Galileo Project Independent Research Affiliate Cambridge USA Consortium for The Scientific Understanding of Natures Mysteries Holbrook USA Institute of Electrical and Electronic Engineers Washington USA American Academy of Environmental Engineers and Scientist Annapolis USA Independent Researcher Holbrook USA

A ten-month field research study was meticulously conducted at Robert Moses State Park (RMSP) on the south shore of Long Island, NY. The objective was to determine if aerial phenomena of an unknown nature exist over a coastal location and to characterize their properties and behaviors. Primary and secondary field observation methods were utilized in this data-centric study. Forensic engineering principles and methodologies guided the study. The challenges set forward were object detection, observation, and characterization, where multispectral electro-optical devices and radar were employed due to limited visual acuity and intermittent presentation of the phenomena. The primary means of detection utilized a 3 cm X-band radar operating in two scan geometries, the X- and Y-axis. Multispectral electro-optical devices were utilized as a secondary means of detection and identification. Data was emphasized using HF and LF detectors and spectrum analyzers incorporating EM, ultrasonic, magnetic, and RF field transducers to record spectral data in these domains. Data collection concentrated on characterizing VIS, NIR, SWIR, LWIR, UVA, UVB, UVC, and the higher energy spectral range of ionizing radiation (alpha, beta, gamma, and X-ray) recorded by Geiger-Müller counters as well as special purpose semiconductor diode sensors.

Mott devices, featuring low hardware cost and high energy efficiency, have been demonstrated as a key oscillatory element in artificial neurons to enable spiking neural networks(SNNs) such as conversionbased SNNs(CSNNs). However, there will be inevitably non-ideal fluctuation in the oscillation behavior,causing the accuracy degradation of networks. In this paper, we investigate the Mott neuronal oscillation fluctuation(NOF) through experiments and modeling. The results show that the NOF phenomenon conforms to Gaussian distribution and originates from thermal fluctuation induced switching voltage variations. We construct a two-layer CSNN for image recognition tasks to study the NOF effect and propose the activation function boundary(AFB) method to strengthen the stability of the network. The results indicate that AFB can improve the accuracy of CSNN by up to 15.5% by tightening output distribution.

Transformer for the Design of Automatic Control Systems with Prefilters

引用

World Journal of Engineering and Technology 2024年第3期12卷 575-586页

作者： Isaac Hughes john F. O’Brien Department of Electrical Engineering and Computer Science University of Wyoming Laramie USA

A machine learning model, using the transformer architecture, is used to design a feedback compensator and prefilter for various simulated plants. The output of the transformer is a sequence of compensator and prefilter parameters. The compensator and prefilter are linear models, preserving the ability to analyze the system with linear control theory. The input to the network is a window of recent reference and output samples. The goal of the transformer is to minimize tracking error at each time step. The plants under consideration range from simple to challenging. The more difficult plants contain closely spaced, lightly damped, complex conjugate pairs of poles and zeros. Results are compared to PID controllers tuned for a similar crossover frequency and optimal phase margin. For simple plants, the transformer converges to solutions which overly rely on the prefilter, neglecting the maximization of negative feedback. For more complex plants, the transformer designs a compensator and prefilter with more desirable qualities. In all cases, the transformer can start with random model parameters and modify them to minimize tracking error on the step reference.

人类目前正面临着巨大的挑战,其中最大的挑战包括向全球80多亿人口提供充足的粮食,日益频繁的像新冠感染(COVID-19)这样的的病毒大流行,以及全球变暖和污染造成的不可挽回的地球环境恶化。而应用蘑菇生物学可部分解决这些挑战。蘑菇生物学是真菌学的一个分支,专门研究蘑菇真菌,由三个分支组成:蘑菇科学,描述与蘑菇栽培相关的活动;蘑菇生物技术,侧重于使用蘑菇和蘑菇衍生产品增进健康和福祉,预防和治疗疾病;蘑菇生物修复,涉及改善环境质量的特性。蘑菇既可以在大型工业规模的生产设施中培养,也可以在资本密集型操作不合适的情况下培养。在后一种情况下,作为“家庭手工业”的蘑菇生产可以丰富当地人口的饮食,特别是在蛋白质缺乏的地区,解决可耕地短缺的问题,特别是为妇女提供就业机会(从而提高她们的社会经济地位),还可作为经济作物为农民创造额外收入。蘑菇栽培过程中的持续技术改进和创新不断增加生产能力,提高产品质量,并在商业规模上扩大人工/半人工栽培的物种数量。蘑菇和蘑菇衍生产品(蘑菇营养药物)具有广泛的药用价值,包括抗肿瘤、抗癌、抗氧化、保肝、抗糖尿病、抗微生物、降低胆固醇、保护基因,以及预防动脉粥样硬化、心血管疾病、慢性炎症、自身免疫性疾病以及与神经退行性疾病相关的认知功能障碍。研究最广泛的蘑菇药理活性成分包括多糖(特别是β-葡聚糖)、多糖-蛋白复合物、三萜、凝集素和真菌免疫调节蛋白。蘑菇在农业也可用于天然生物控制剂、食品产业中的调味化合物和化妆品中的特性成分(药妆)。蘑菇转化栽培基质中木质素成分的生化系统也可用于降解污染我们环境的各种顽固的合成化合物(如合成染料、多环芳烃、多氯联苯、多溴联苯醚、杀虫剂和弹药)。在自然和人为管理的生态系统中,菌根菌对恢复和增强森林健康和多样性起着核心作用。菌根的共生通常在最极端的条件下达到最大,如在贫瘠的土壤、干旱或金属污染环境中。据报道,树木根部菌根真菌可保护树根免受几种根部病原真菌带来的有害影响。除了生态重要性外,黑块菌(黑松露)和松茸等菌根物种因其烹饪特性而备受重视。

Oral Hygiene in the Presence of Orthodontic Therapy

引用

Journal of Biosciences and Medicines 2024年第2期12卷 98-110页

作者： Emmanuel john Aryeetey Hicham Benyahia Fatima Zaoui Faculty of Dental Medicine Mohammed University in Rabat Rabat Morocco

Orthodontic treatment offers great advantages in improving facial and smile aesthetics, self-confidence and the function of the stomatognathic apparatus. The pursuit of these advantages makes use of orthodontic appliances that could be fixed or removable. However, it’s worth stating that these appliances interfere with tooth brushing, making it more difficult to brush teeth effectively. Orthodontics appliances therefore promote the accumulation of dental plaque, which results in both quantitative and qualitative changes in the oral microbiota, hence, exposing patients to several adverse effects such as White spot lesions, dental caries, periodontal pathologies and halitosis. For this reason, oral assessment of patients before, during and after treatment is necessary as well as oral hygiene instructions and motivation. Orthodontists therefore, should educate patients on oral and periodontal hygiene in order to control dental and periodontal complications. Prescriptions of plaque control materials adapted to each patient are done in order to optimize the final result and minimize unwanted complications.

Effect of Some Physical Factors on Interrill Erosion of Soils in Gidan-kwanu Area, Nigeria

引用

Journal of Environmental Protection 2024年第4期15卷 475-484页

作者： Ebierin Akpoebidimiyen Otuaro john Jiya Musa Micheal Abolarin Department of Civil Engineering Faculty of Engineering Maritime University Okerenkoko Nigeria Department of Agriculture and Bioresources Engineering Federal University of Technology Minna Nigeria

Savanna regions in Nigeria face environmental degradation and barren land, negatively impacting food and agricultural productivity. Inter-rill erosion occurs due to raindrop impact and transport, particularly on hill slopes. A study was conducted using a sprinkler rainfall simulator and plot experiment to study soil erosion processes. Soil samples were collected from four farms in Gidan kwanu, with varying moisture content. Sand content ranged from 46.0% to 76.20%, silt from 11.30% to 23.50%, and clay from 11.0% to 30.0%. Uncultivated and bare land had a higher average porosity (15.47% and 14.99%), while cultivated land had lower porosity (14.4%). The study found that most people in Gidan-kwanu primarily practice farming, which is season-dependent and rain-fed. Soil type and texture significantly contribute to inter-rill erosion, with cultivated and uncultivated soil being more resistant to erosion than bare land soil. The study concluded that farming practices in Gidan-kwanu are primarily season-dependent and rain-fed. Soil type and texture significantly contribute to inter-rill erosion, with cultivated and uncultivated soil being more resistant to erosion than bare land soil.
