Cephalometric norms for a sample of Emirates adults

Open Journal of Stomatology 2011年第3期1卷 75-83页

作者： Huda M. Abu-Tayyem amna H. Alshamsi Sayed Hafez Eman Mohie ElDin 不详

Introduction—European-American norms are still used in the orthodontic treatment of Emirates patients despite the different ethnic backgrounds of the Emirates. The purpose of this study was to formulate cephalometric norms for lateral cephalometric mea-surements of Emirates adults and to study gender differences. Methods—Lateral cephalometric radio-graphs of 176 Emirates adults, 91 males and 85 fe-males, were selected according to the following crite-ria;an age range between 19 to 25 years, esthetically pleasing and harmonious faces with balanced and acceptable profiles and occlusions, normal skeletal and dental relationship, all permanent teeth present, and no history of orthodontic treatment or facial trauma. The mean values and standard deviations of 91 angular and 21 linear cephalometric variables were calculated using the Dolphin version 10.5 soft-ware package. The resulting norms for Emirates male and female groups were compared using a student t-test. Results—Several statistically significant gender differences were noticeable. Skeletally, Emirates males showed significantly greater (p < 0.001) total, anterior, and posterior cranial base lengths as well as longer facial heights, greater SGn-FH (°), ANS Xi PM (°),and FH/MP (°) angles than females. In addition, Emirates males had significantly greater (p < 0.001) Co-A (mm), Co-Gn (mm), and significantly greater (p < 0.05) Pog-N vert (mm) than females. Dentally, Emirates males had significantly greater (p < 0.05) UI-SN (°) and U1-NA (°), U1-NA (mm), and L1-NB (mm) (p < 0.001) than females. For soft tissue measurements there were significant gender differences (p < 0.001) for all angular and linear measurements except for lower lip to E-plane and nose prominence measurements which have no significant gender difference. Emirates males revealed greater measurements than females except for soft tissue con-vexity, Z-angle, and both upper and lower lips pro-trusion which were significantly greater in Emirates females.

Support vector machine (SVM) has become an increasingly popular tool for machine learning tasks involving classification. In this paper, we present a simple and effective method of detect and classify hard exudates. Automatic detection of hard exudates from retinal images is worth-studying problem since hard exudates are associated with diabetic retinopathy and have been found to be one of the most prevalent earliest signs of retinopathy. The algorithm is based on Discrete Cosine Transform (DCT) analysis and SVM makes use of color information to perform the classification of retinal exudates. We prospectively assessed the algorithm performance using a database containing 1200 retinal images with variable color, brightness, and quality. Results of the proposed system can achieve a diagnostic accuracy with 97.0% sensitivity and 98.7% specificity for the identification of images containing any evidence of retinopathy.

The confluence of cheap wireless communication, sensing and computation has produced a new group of smart devices and by using thousands of these kind of devices in self-organizing networks has formed a new technology that is called wireless sensor networks (WSNs). WSNs use sensor nodes that placed in open areas or in public places and with a huge number that creates many problems for the researchers and network designer, for giving an appropriate design for the wireless network. The problems are security, routing of data and processing of large amount of data etc. This paper describes the types of WSNs and the possible solutions for tackling the listed problems and solution of many other problems. This paper will deliver the knowledge about the WSN and types with literature review so that a person can get more knowledge about this emerging field.

Effect of Growth Media, pH and Temperature on Yeast to Hyphal Transition in <i>Candida albicans</i>

Open Journal of Medical Microbiology 2013年第3期3卷 185-192页

The transition of C. albicans from unicellular yeast form to filamentous form i.e., pseudohyphae and hyphae is referred to as morphogenesis. C. albicans has the ability to respond to environmental conditions and accordingly changing its cell morphology. Three main morphological forms of C. albicans are unicellular yeast, pseudohyphae and hyphae. The effect of different growth media (Horse serum medium, RPMI-1640, MSGB), incubation temperatures (34°C, 37°C, 40°C) and pH values (5.4, 6.4, 7.4) on germ tube production by C. albicans was evaluated. Horse serum medium noticeably promotes filamentation while RPMI-1640 medium shows moderate filamentation and MSGB media shows moderately low filamentation. The germ tube of C. albicans developed early in 1.5 hr at high temperature i.e., 40°C. Incubation temperature of 37°C was associated with highest germ tube formation while 34°C shows low filamentation. A pH of 5.4 also induces low filamentation, pH 6.4 gives moderately lower than pH 7.4. A pH of 7.4 was best suited for germ tube induction. The peak of mycelium production appears between 1.5 and 6 hr after inoculation of C. albicans culture. These results suggested that environmental factors are important in selectively favoring yeast or hyphal form, most important being the growth medium, incubation temperature and external pH value.

Allogenic Stem Cell Transplantation and COVID-19 Antibodies: Mechanistic Insights and Recipient Concerns

Collecting umbilical cord stem cells is widely practiced due to its numerous benefits. Over the past decade, umbilical cord stem cells (UCSCs) have shown effectiveness in treating various conditions, such as bone pathologies, neuropsychiatry disorders, hereditary diseases, and metabolic disorders. However, factors like immunization affect the quantity and quality of cord harvesting. Studies suggest that antibodies from the mother pass through the umbilical cord to protect the infant against infections. Cleaning the umbilical cord before stem cell extraction is crucial to maintain sterility and cell integrity. Vaccinating a female donor, including for COVID-19, typically does not directly affect the stem cells. Although vaccines aim to trigger an immunological response, they generally do not affect the donor’s stem cells.

Case Reports in Clinical Medicine 2023年第10期12卷 408-417页

Invasive fungal infections have grown significantly over the last two decades, owing to an increase in immunocompromised hosts and geriatric patients. When the host’s defenses are compromised, such infections are associated with severe morbidity and mortality. Here, a rare case of fungal infection in a 61-year-old immunocompetent male patient from Saudi Arabia was reported, who suffered from pulmonary hemorrhage and Systemic Lupus Erythematous. Bronchoalveolar Lavage was used as a diagnostic tool to identify the fungus reported in the case. The pathogenic fungal specie identified as Magnusiomyces capitatus, in macroscopic and microscopic morphological characteristics of the colonies. Based on clinical evidence, liposomal amphotericin formulation was recommended for initial therapy against fungal infection. Also, liposomal amphotericin B induced mycological eradication up to 70 percent in patients with proven Magnusiomyces capitatus infection. In addition to addressing suspected Systemic lupus erythematosus, the patient’s health has improved with no evidence of pulmonary bleeding and hemoptysis.

磷对于生物是一种不可替代且不可再生的元素。磷矿在全球的储备量是有限的,磷矿的开采速度也在逐年递增,在将来会导致磷资源枯竭。因此磷的回收再利用对于可持续发展至关重要。由于生物除磷会产生富含磷的活性污泥,因此释放活性污泥中的磷放并加以回收是一种可行的方法。通过投加化学药剂强化除磷效果在活性污泥法污水处理中较为常见,但这会增加活性污泥释磷的难度。因此,本文将研究碱处理释放投加铝盐的活性污泥磷的机理,考察了三个污水处理厂(清河、北小河及小红门污水处理厂)的活性污泥在碱处理后的释磷效果、金属溶出以及随pH的变化细胞完整性的变化。研究结果表明,当碱处理的pH上升至12时,污泥液相中的磷浓度显著上升(>200 mg/L),在碱性条件下,污泥液相的磷浓度与铝浓度具有相关性。将污泥碱处理的pH从12调至8的结果表明,实验中的所释出的磷主要是与铝结合的磷,且细胞的完整度与污泥液相中磷的浓度没有显著的相关性。在本研究中,我们还考察了厌氧消化污泥碱处理的释磷情况以及所释放磷的种类,结果显示在pH为8、10到8及12到8的条件下释出的磷浓度随厌氧消化时间的增长而逐渐升高,厌氧消化时长达到15天时,碱处理释放的磷最多。结果表明在厌氧消化结束时(30天)磷灰石态磷增加了,非磷灰石态无机磷减少了7%左右。SMT磷提取结果表明无机磷和有机磷在厌氧消化的过程中随的改变而发生了变化。碱处理释放了非磷灰石态的磷.当碱处理的pH从10,12调回8时释放出的非磷灰石态无机磷形成了磷灰石态的磷,而在碱性条件下,磷灰石态的磷比非磷灰石态的磷更难溶解。碱处理后污泥中正磷酸盐的含量从69%上升至87%,这说明碱处理使磷向无机磷转变。因此,pH调节有利于将污泥中多种形态的磷向无机磷转变。
