Expression of matrix metalloproteinase-2 and 9 with their inhibitors, tissue inhibitors of metalloproteinase-1 and 2 in oral lichen planus
No full textObjectives: The study aims to explore the expression of the matrix metalloproteinases (MMP-2, -9) and their inhibitors (tissue inhibitors of metalloproteinase [TIMP]-1, -2) as well as the correlation between them in the different morphological forms of oral lichen planus (OLP). Materials and Methods: 28, formalin-fixed, paraffin-embedded specimens of OLP and six specimens of squamous cell carcinoma, which served as the positive control and another six normal oral tissue specimens, which served as the negative control were used in this study. All the 40 samples were investigated immunohistochemically for the expression of MMP-2, -9 with their tissue inhibitors TIMP-1, -2. Results: The immune reactivity of MMP-2, -9, TIMP-1 and TIMP-2 were detected at significant levels within the keratinocytes and lymphocytes of the OLP cases when compared with the normal control group (P < 0.0001) while the MMP-2, -9 immune reactivity was found to be about 1/5-1/10 of that detected in the positive control group. The TIMP-1, -2 were strongly expressed in both keratinocytes and lesional lymphocytes. However, no significant relationship was discovered between the expressions of MMP-2, MMP-9, TIMP-1 and TIMP-2 and the morphological types of OLP. Conclusion: A distinct imbalance is observed between the MMP and TIMP activities when the normal mucosa and OLP sample are compared. The TIMP intensities, on the other hand, were found to be very high, suggesting an endogenous protection of the basement membrane against the degrading effect of the MMP enzymes
Prevalence of odontogenic cysts and tumors among UAE population
No full textBackground: Odontogenic cysts and tumors are lesions that tend to arise from the tooth apparatus or its remnants. Odontogenic cysts and tumors constitute an important aspect of oral maxillofacial pathology as they can be diagnosed in general dental practice. Aim: The purpose of this study was to evaluate the prevalence of odontogenic cysts and tumors diagnosed in the UAE and to compare the results with findings in the literature. Materials and Methods: Data of odontogenic cysts diagnosed between 1990 and 2010 were collected from the files of the Oral Pathology Laboratory and Oral Surgery Department of Tawam Hospital, UAE. Results: Most of the prevalent odontogenic cysts are radicular cysts (69.1%) - followed by dentigerous cysts (7.9%). Among the odontogenic tumors, the most prevalent is odontoma (12.2%) followed by ameloblastoma (2.9%). The middle and posterior mandible was the most common anatomic site for the formation of cysts and tumors. In fact, 93.4% of patients over 40 years presented with odontogenic cysts, whereas 6.3% presented with odontogenic tumor. Odontoma as odontogenic tumor was seen mostly in the first and second decades of life. Conclusion: The prevalence of odontogenic cysts was similar to that reported in the literature, with inflammatory cysts occurring most frequently
Spatial analysis of mandibular condyles in patients with temporomandibular disorders and normal controls using cone beam computed tomography
No full textABSTRACT
Objectives: The aim of the study is to investigate the condylar position and its relation to articular eminence and axial condylar angle in temporomandibular joint disorder (TMD) patients and in normal controls using cone beam computed tomography (CBCT). Materials and Methods: CBCT temporomandibular joint (TMJ) images of 70 participants (38 males and 32 females, mean age 26.4 years) were analyzed. They were divided into control group (including 35 subjects) and study group (including 35 subjects). Linear measurements of joint space and condyle determined the condylar position of each TMJ. Articular eminence height and inclination were also measured with axial condylar angle to determine its relation to condylar position. Independent and paired sample t-test was applied to compare between the groups and TMJ sides of the same group at significance level of 0.05. Results: Statistical significant differences were found between males and females of both groups regarding superior joint space (SJS), lateral joint space, A-P, and M-L condyle distance (P < 0.05). SJS, medial joint space (MJS), and eminence angle were greater (P < 0.01) in male's joints with TMD with flatter axial condylar angle (P < 0.05), when compared with normal TMJ counterpart. Females TMJs showed significantly higher values of MJS of affected side when compared with normal counterpart with flatter axial condylar angle (P < 0.05). Conclusion: Superior and MJS parameters were the ones that showed significant differences between affected and nonaffected joints. The mean axial condylar angle was smaller in joints with abnormal TMJ. This indicates that the condyles of the affected joints may rotate inward.</jats:p
Magnetism in drug delivery: The marvels of iron oxides and substituted ferrites nanoparticles
No full textIn modern drug delivery, seeking a drug delivery system (DDS) with a modifiable skeleton for proper targeting of loaded actives to specific sites in the body is of extreme importance for a successful therapy. Magnetically guided nanosystems, where particles such as iron oxides are guided to specific regions using an external magnetic field, can provide magnetic resonance imaging (MRI) while delivering a therapeutic payload at the same time, which represents a breakthrough in disease therapy and make MNPs excellent candidates for several biomedical applications. In this review, magnetic nanoparticles (MNPs) along with their distinguishable properties, including pharmacokinetics and toxicity, especially in cancer therapy will be discussed. The potential perspective of using other elements within the MNP system to reduce toxicity, improve pharmacokinetics, increase the magnetization ability, improve physical targeting precision and/or widen the scope of its biomedical application will be also discussed

The owner of the manuscript purchased it during a book fair in 2011 in Yola, the capital of Adamawa State. The publication date is not indicated but it is evidently a complete unbound copy of a market edition.This undated manuscript is a complete copy the Arabic work by Shaykh ʿAbd al-Bārī al-Rafā‘ī al-ʿAshmāwī, which is explained using Kanuri Ajami glosses by Goni Abubakar Koloma. The book is among the most well-known, well-read and most-cited authorities on Islamic rituals in northern Nigeria and West Africa. Considered more advanced than Qawā’id and Al-Akhdarī, Al-ʿAshmāwī is popular among clerics and students of Islamic jurisprudence. Like Al-Akhdarī and other similar books on Muslim rituals, this text contains many chapters dealing with the significance of good intent, purification of the heart, body, and the environment, ablution and ritual prayers, requirements of ritual prayers, factors that invalidate ritual prayers, and common mistakes in ritual prayers and how to correct them.The contents of this collection were developed with support of the Title VI National Resource Center grant # P015A180164 from the U.S. Department of Education.

Mada'in Salih, a Nabataean town in north west Arabia: analysis and interpretation of the excavation 1986-1990
No full textThis research concerns Mada'in Salih, an archaeological site in north-west Saudi Arabia. Historically, it was part of the Nabataean kingdom which flourished in northwest Arabia (Jordan, parts of Syria, Palestine and some parts of Saudi Arabia), with Petra in Jordan as its capital. The Nabataeans were famous for their trading role, as they transported frankincense and myrrh and exported balsam and bitumen. They built monumental tombs in Petra and Mada'in Salih as well as other public buildings such as temples theatres and baths. They were also famous for their skills in hydraulic engineering and the production of very thin, distinctively painted pottery. Mada'in Salih was an important station on the trade route which linked south Arabia with Mediterranean countries. The main feature of the site is the monumental tombs, which are about eighty in number, some of them dated and bearing inscriptions. Those inscriptions are in Aramaic and usually contain information about the owner name, legal rights, and occasionally the mason's name. Little was known about the site's history and other aspects such as the economy, culture, society and religions prior to the excavation. Various questions were raised which the thesis attempts to address. The archaeological work conducted on the site included a survey, several trenches around the town wall and in front of some of the tombs as well as an excavation in the settlement area. The excavation revealed a private house which furnished us with information regarding house planning, building techniques and materials. A large amount of pottery, small finds and coins were recovered, studied and classified. The results added some information to what was already known about the Nabataeans in general and Mada'in Salih in particular. The site had witnessed its peak during the first century A.D. As most previous archaeological work had been carried out in the northern parts of the Nabataean kingdom, the results of this excavation are important for comparative studies between this, the largest Nabataean settlement centre in the south, to the centres of the north. The trade which had been an important factor in the establishment of the site declined when the trade route was shifted from land to sea by the Romans during the last half of the first century A.D
Modernization in a traditional society: the case of Saudi Arabia, 1990
Get PDFSeveral states of the third world have experienced dramatic changes brought about by the process of modernization. This modernization began in the late 1950s. The level, rate and consequences of modernization vary from country to country. The author is undertaking the task of looking at the third world as a whole, to see the level of achievement and impact of modernization on the social and political environment. With this in mind, special emphasis is on Saudi Arabia as our case study. Of all the third world countries, Saudi Arabia's state of growth in modernization has grown much more rapidly than any other third world country, even though it is an unsecular government. Oil wealth made it possible for the state to speed up the process of social mobilization whereby major achievements were accomplished with respect to agriculture, education, foreign trade, health services, industry and petroleum. Finally, the study discusses to what extent the process of modernization was able to achieve its goals and overcome challenges of the old and the new waves in their competition for the loyalty of the Saudi citizen

There is no date of publication of the text, but the owner said that he grew up knowing that it was part of his father’s personal collection.This manuscript is a copy of the work of Shaykh Muḥammad b. Yūsuf al-Sanūsī (aka Abū ʿAbdullāh) with extensive explicatory marginal and interlinear Kanuri glosses. This short book is popularly known as Al-Sanūsiyya. There are many versions of the work, including those that have detailed commentaries. But this version is the short form. It is a foundational text on tawḥīd (oneness of Allāh). Al-Sanūsiyya al-Sughrā has been a popular work that is read, memorized, and chanted by students of the tsangaya traditional Islamic schools. It deals with attributes of Allāh and the features that are not His. It also deals with many messengers of Allāh and concludes with insights about Prophet Muḥammad. An outstanding feature in this manuscript is a pattern marking at the center (page 20) and on the cover page. Such markings are commonly found on Quranic manuscripts and not in books like this one.
