The practice of restorative dentistry dates back to the 1st century AD. These restorations are done to restore form, function and esthetics. In current restorative practice, the materials to choose from are dental amalgam, composite resin (and its modifications) and glass ionomer cements (and its modifications). Dental amalgam was the material of choice for nearly two centuries. This was because it has such properties as durability, ease of placement, high compressive strength and it was cheap. It however was not esthetic and there was concern of its use due to its mercury content. Composite resin was initially only restricted to the anterior portion of the mouth and for small Class I cavities this was because though it was esthetic, it lacked strength, but with modifications, new research now shows it can be a good substitute for dental amalgam. Glass ionomer cement bonds to both enamel and dentine, it also has sustained release of fluoride which helps to remineralize tooth structure as well as prevent future caries occurrence. It can now also serve as a definitive restoration in the posterior stress bearing portion of the mouth. Although dental amalgam has been the material of choice almost two centuries, there is now a paradigm shift towards non-amalgam restorative materials. This paradigm shift has been occasioned by the need to restore tooth with materials that best match the tooth in terms of function and esthetics. The biomimetics are in as they fulfil the conditions and conserve tooth tissue.

Introduction: A much controversy exists regarding treatment of neck of femur fractures in elderly. Currently, choices available options for an Orthopaedic surgeon for treating these fractures in elderly are Canulated cancellous screw fixation, Girldstone, unipolar hemiarthroplasty, bipolar hemiarthroplasty and total hip arthroplasty. One of the most common treatments of Garden type-III & IV fracture of femoral neck in elderly in low- and middle-income countries is bipolar hemiarthroplasty. This study was conducted to evaluate functional outcome of fracture neck of femur treated with cemented bipolar hemiarthroplasty in elderly. Materials and Methods: Multicentered based non randomized quasi experimental prospective study was performed in Rajshahi Medical College Hospital, Dhaka Medical College Hospital and Spine & Orthopaedic Specialized Centre, Rajshahi, Bangladesh from January 2010 to December 2019.Total number of patients n=1156 with fracture neck of femur were operated with cemented bi-polar prosthesis of femoral component and their functional outcomes were assessed on the basis of modified Harris Hip Score. Results: At the end of 10 year after surgery, the functional results were analyzed by SPSS 18.0. All patients were in the age group of 50-85 years with mean age of 62.09 years for males and 69.42 years for females. 48% percent of the patients had sub-capital fracture radiologically, while 52% had Transcervical. In 68% of cases, the mode of injury was trivial trauma. Complications observed were superficial surgical site infection (1%), affected sided mild hip pain (15%), LLD < 1.25 cm of 0.01% and post-operative dislocation within 3 months in another patient. There were 64% excellent results, 28% good results and 8% fair results. No poor results were found in our study. Conclusions: Elderly neglected patients with displaced fracture of neck femur are able to ambulate early after Cemented bipolar hemi arthroplasty. The complication rate is very low and pre injury functional status is restored in majority of patients.

The torque will be in proportion to the crank and linkage length. That may be fitted to the stroke ratio γ well. The bigger the γ is the bigger the torque is. The crank acceleration and block angle will be low when the γ becomes big. The linkage acceleration and speed may incline as the stroke ratio and rotation is big. The movement will be big when the stroke ratio is small and the rotation is inclining on the crank linkage mechanism in vehicle

Noonan syndrome is a genetic disorder characterized by facial dysmorphism and several birth defects including lymphatic abnormalities. There are familial cases and sporadic cases. In practice, it is sometimes very difficult to confirm the diagnosis, as the manifestations are variable and & quot; subtle & quot; for the non-specialist. We report the case of a patient in whom the diagnosis was made late at the age of 37 years and whose reason for consultation was an increase in abdominal volume related to chylous ascites. Chylous ascites in Noonan syndrome seems to be more frequent than expected hence the need to know how to evoke this syndrome in its presence especially since there is a typical dysmorphic picture.

This paper aims to study women’s realities and conditions through motherhood realities in Linda Pastan’s poem entitled “Marks”. Indeed thanks to the microcosm of a familial and motherhood reality, the poet Linda Pastan sheds light in general to the macrocosm of familial and motherhood reality in the whole society and further to the macrocosm of women’s realities and conditions in the society. It is like a cry from the heart of a woman which calls for anyone attention about women’s conditions and sufferings in family, in society, and further in the world. In fact, thanks to an ironic style she depicts the daily life of a mother in her own family showing the difficulties she encounters by explaining the household sufferings. This ironic depiction is indeed a kind of metaphor to denounce the ingratitude or ungratefulness on the part of the other members of the family (husband, son and daughter). When transcending the familial context described by Linda Pastan, we observe obviously that this poem is topical about women’s realities and conditions, and also that the problem of women’s conditions and sufferings is universal and a world concern. On the basis of this simple but true reality and in a thorough analysis following sociocriticism, a psychoanalytic criticism, a feminism perspective and stylistics, we will study on the one hand, motherhood realities and women’s conditions and sufferings and on the other hand, we will analyze family or people or society ingratitude toward women and the need for women recognition and emancipation.

Background and objectives: Pit and fissure sealants have been long suggested as the method of preventing dental caries. The aim of the study was to provide an overview of the latest evidence on clinical effectiveness of pit and fissure sealants in prevention of dental caries. Materials and methods: Literature survey was carried out from 2010 to 2020 in electronic databases such as PubMed, Google Scholar and Virtual Health Library database using key words such as “Pit and fissure sealants” and “systematic reviews,”. The searches revealed 457 articles out of which 5 were selected after reading the full text articles. Results: The review of 5 articles revealed that high viscosity GIC and resin-based sealants have similar caries-preventive efficacy in permanent molar teeth after 48 months. The evidence for a potential superiority of high viscosity GIC over resin-based sealants after 60 months is still low. Sealants alone had a 2- to 3-fold higher risk of arresting or reversing lesions (moderate certainty for all comparisons) as compared to no treatment. In comparison to no therapy, the combination of sealants and 5% NaF varnish was the most effective in arresting or reversing lesions. When compared to varnish, Fissure sealants had limited superiority in minimizing occlusal caries. Conclusions: The evidence suggests that sealing pit and fissures are effective in prevention of dental caries however it is hampered by high risk of bias. Hence, future studies with high quality should be conducted assessing the effectiveness of different types of sealants.

Islamic banking has developed as an important tool for the progress of the economy in many countries because it based on investment and financing projects globally, reported by World Bank's 2015 report. In many parts of the world, Islamic economics has the prospective to contribute and to face the encounters of termination of poverty and rising development. This study undertaken in Bahrain in order for investigate the nexus of Islamic banking and economic growth. Bahrain become one among the most developed Islamic banking activities and other Islamic instruments like Takaful, capital market and so on. This paper based on two correlated specific objectives that were survey the long-term relationship and causal linkage between economic growth and Islamic banking in the Bahrain. Although Bahrain have many Islamic banks operated but for the purpose of the study and research problem with availability of data only one bank was selected which called Al Salam Bank. This bank have good experience, existed for long time and have already announce as one of the as the best and better performance Islamic bank in Bahrain. The study based on quantitative approach and data was secondary and collected from al salam annually financial statements and world bank data set for the period from 2000 to 2020 which was time series. Study variables were Islamic bank’s assets, Great fixed capital formation, GDP per capital and foreign direct investment. Methodology which applied were the unit root problem was tested, then testing the co-integration with long run structural model, then the VECM, then Variance decomposition then Impulse Response Function and finishing persistence profile. Findings shown that Islamic banking in Bahrain have positive long run with positive short run relationship with economic growth. Also result shown that Islamic bank asset take the leading variable on the affect the GDP in Bahrain which supported by VECM. These outcomes give implication that the growth and development of Islamic banks in Bahrain have advantageous on the economy and households income of Bahrain. So it is better for police markers in Bahrain to increase more for taking considerable efforts for Islamic banks operation in order to provide much positive relation with their economy and to be a source for improvement of other sectors of economy in Bahrain.

Aim: The aim of this study was to detailed analysis of the donor corneal tissue using Eye Bank Specular Microscope (EBSM). Materials and Methods: Retrospective analysis was done for 408 donor corneas procured and processed between April 2016 and March 2020, at an Eye Bank in a Tertiary Care Hospital for Endothelial cell density (ECD), coefficient of variance (CV), and percentage of hexagonality (6A) and were compared across different age groups & gender of the donor tissue. Results: The mean age of the donors was 66.78 ± 17.27 (range 12–95 years). The mean ECD of the donor cornea was 1400.65 ± 627.01 cells/mm2; the average CV was 37.5 ± 18.2; and the average percentages of hexagonal cells were 44.9%. The cell count was significantly greater in the donor corneas in age groups of <20, 21-30 & 41-50 years when compared to rest of the age groups. There were no significant differences between the age groups on basis of CV and 6A. The ECD of the male donors (65%) was more than that of female donors (35%). Conclusion: ECD is significantly greater in younger age group as compared to older age groups; however, there were no significant differences in CV and 6A. Endothelial cell analysis by Eye Bank Specular Microscopy is a great tool for the grading of donor tissues, its subsequent utilization for corneal transplantation & prognostic value of the graft survival.

Streptokinase is a novel bacterial enzyme that binds with plasminogen and activates it. Streptokinase is produced by different species of streptococcus. Activity of streptokinase is determined by different methods such as fibrin clot method, casein hydrolysis and Chromozym test. High production of streptokinase was obtained in experiments with batch cultures. Production of streptokinase increases 2-3 times in continuous culture. Different species of streptococcus was selected for Optimum production of streptokinase by using different concentration of substrates such as CSL, molasses, sugarcane bagass, rice polishing. Maximum activity was overserved by 0.3% CSL, 0.5% molasses, 0.4% sugarcane bagass and 0.5% rice polishing. Physical parameters such temperature, pH at optimum conditions (370C, 7.0) enhance the streptokinase activity by using RSM. Nitrogen sources, carbon sources, incubation time, Growth factors such as glycine, thiamine and traces elements such as FeSO4, MgSO4, when uses in limited amount enhance the enzyme production. 1% (v/v) inoculum increase the yield of streptokinase (0.360 U/ml).

Introduction: Tuberculosis is still commonly found in many developing countries. Spinal tuberculosis can cause vertebral deformity and neurological disorders. It was discovered thousands years ago and its management was aimed to eradicate infection and maintain the integrity of the vertebrae. Previously, the management of spinal TB was using drugs and external stabilization. Surgical techniques were developed afterwards to clean the infected vertebral segment. Because of the vertebral deformity remained inevitable and had impacts on neurological disorders, new paradigm had been developed by using instrumentation to stabilize the deformity of infected vertebral segment and to restore and maintain neurological function. TNF-a has a major role in immune process of spinal TB. Spinal TB instrumentation uses metal devices composed of ions and particles that can interact each other so it could produce physical and chemical energy that is transmitted to the vertebrae. The energy is expected to enhance the biomolecular and biocellular activity of the body's immune cells so the healing process could be better. Methods: An experimental study was carried out on New Zealand Rabbits which were given TB H37Rv strain infection in the vertebral body. Samples were divided into five groups namely control rabbits, infected rabbits without intervention, infected rabbits treated by instrumentation, infected rabbits given anti-tuberculosis drugs and infected rabbits treated by instrumentation and given drugs. Then the cytokine levels of TNFa were evaluated and compared. Results: The results showed a significant TNF-a level increase in infected rabbits given drugs alone and instrumentation alone compared to infected rabbits without intervention. There was a significant TNFa decrease in infected rabbits given drugs and treated by instrumentation compared to control rabbits and rabbits who received drugs only. Conclusions: Instrumentation can improve the healing process in spinal tuberculosis by increasing the body's cytokine levels.

In every society, when a crime is committed, it affects the victim and the community as a whole thus, promoting criminality and insecurity in the society. This calls for efforts to address the worrisome situations in order to heal the plight of the victim who suffers injuries as a result of crime waves. It should be noted that from investigation to trial, victims of crime are faced with numerous challenges. These challenges range from participating in the investigation and trial and more importantly adequate compensation for damage suffered following the commission of an offence. The key guiding principle in criminal justice for victims of crimes is to ensure that the person who suffers injuries or losses is compensated or restituted. Injuries or damage suffered by victims’ results from the commission of offences by either physical or juristic persons. Some of these offences include: murder, assaults, sexual offences, theft, destruction, human rights violations, environmental hazards, etc. Most at times the victims never have their compensations paid by the perpetrators of these heinous crimes. The preeminent query is whether there are options available for victims to ensure their compensations when real offenders cannot repair the harm. This paper through a content analysis, seeks to examine the challenges of victims’ rights to compensation in the administration of criminal justice in Cameroon. It seeks also to examine whether there are existing legal and institutional framework adequate and efficient in addressing the plight of victims of crime with regard to compensation.

Leiomyoma is the most common benign tumor of uterus but rarely it may be seen in round ligament, uterosacral ligament, inguinal canal and vagina. Vaginal fibroid more commonly arises from anterior vaginal wall and present with varied clinical features. Here we report a case of primary subfertility with vaginal leiomyoma, arising from anterior wall of vagina. Case Description: A 31-year-old nulliparous lady attended the Reproductive Endocrinology and Infertility Clinic with the complaints of infertility and something coming down per vagina for 6 years. Vaginal examination revealed a mass originating from anterior and lateral vaginal wall, pulling the cervix up. On bimanual examination, a 3x3 cm mass is felt through the anterior and lateral vaginal wall but upper limit could not be delineated. Transvaginal sonography showed a mixed echogenic, predominantly hypoechoeic mass in lower part of cervix and anterior vaginal wall. Myomectomy was done through vaginal route along with laparoscopy with chromopertubation test and hysteroscopy. Histopathology report revealed leiomyoma. She was counseled for IVF due to bilateral tubal block on dye test.

Football its popularity compares to other sports at any age level, there is a lack of information on the technical, physiological and conditioning aspects of children players. Therefore, the purpose of this study was to investigate the physical, muscular performance and speed of 12-year-old football players. Eighty-two footballers who were actively participating in the Albanian Children's Championship participated in the study. Batteries for fitness testing: Standard height, body weight and calculated body mass index (BMI), speed (30m sprint), vertical jump, and rated lower body muscle strength (vertical jump) were the tests selected for to measure. Data were subjected to statistical analysis using the ANOVA method. Identifying the physical and physiological characteristics of football players provides insight into the physical and physiological qualities that are important to becoming a team member and playing successfully. The most important issue for the coach and football player is to determine the improvement of physical fitness through a well-modeled training programmer. Although anthropometric and physiological profiling is best seen as an objective tool for monitoring young player, physiological data may not be the only predictor of competitive success in football. On the other side, heritage in related physiological standards is an important prerequisite for success in football. Physiological standards play a crucial role in the selection of football talent.

The freshwater shrimp Atya scabra Leach, 1815 is traditionally captured in the Bia river, in the area of the South-Comoé, precisely in Biaka and Aboisso. The aim of this study was to investigate if sexual differences could affect external morphology in freshwater shrimp Atya scabra, to determine sexual dimorphism related to morphological differences during the maturation in this species. Thus, morphometric measurements in 360 specimens of A. Scabra were examined at each study site for sexual dimorphism from August 2014 to July 2015. In Aboisso, mean values recorded at lpp, Lantn and Lantl were 8.5 ± 7.8; 78.5 ± 84.1 and 47.5 ± 47.4 mm in males. The average values obtained were respectively 6.5 ± 4.9; 58.5 ± 46 and 25 ± 24 mm for lpp, Lantn and Lantl in females. In Biaka, Mean values in males were 7.5 ± 7.8; 71.5 ± 55.9 and 37.5 ± 31.8 mm. In females, mean values recorded were 6 ± 5.7; 60 ± 50.9 and 27.5 ± 21.9 mm. Concerning the sexual dimorphism index, the χ2 test showed that there is no significant difference (P > 0.05) between the SDI determined at the level of the width of cephalothorax and the 3rd pair of pereiopod (lpp) in the specimens of Atya scabra of Aboisso and those of Biaka. Analysis of the data shows two modal of distribution in males, females and in both sexes combined. When considering the sexes combined, the young recruits have an average size (Lt) of 83 ± 3.8 mm while the latter was 107.6 ± 12.1 mm in the oldest freshwater shrimps of the species A. scabra captured in Aboisso. But in Biaka, the young individuals had an average size (Lt) of 81.4 ± 4.3 mm. As for the oldest individuals, the value of the estimated average size is 107.0 ± 11.2 mm in the sexes combined. The present study was made in order to have data on the size frequency distribution and the sexual dimorphism index of this species.

Background: An attractive face, no doubt is pleasing to behold, however the definition of an attractive face is subject to factors such as personality, culture, age, ethnic background as well as personal preferences. Beauty, ugliness and handsomeness are subjective attributes ascribed to the facial appearance of individual. Though the determination of each is personal subjective, it is obvious that the human face is the most beautiful and attractive of all the mammals. Hence, this study was aimed at determining whether there is sexual dimorphism in the facial height, nasal height, mandibular height, maxillary height and orofacial height of the Ikwerre people in Rivers State. Materials and Methods: The study was cross-sectional that included males and females of the Ikwerre ethnicity of Rivers state of Nigeria. A total of 1,038 subjects comprising males (585) and females (453) aged between 5 – 45years were used for this study. The parents and grandparents were all from Ikwerre ethnic group. Each subject sat on a comfortable sitting position and then their facial measurements were taken including; facial height, nasal height, mandibular height, maxillary height and orofacial height. Results and Discussions: Results & Discussion: F.H. for males in the age grade 25yrs and above was 106.81±11.58, while for the females 101.24±6.98; N.H. for the males: 37.991±6.126, while for the females 38.344±6.255, Man. H. males: 47.511±8.016, females: 41.975±7.018; Max. H males: 22.08±21.16, females: 20.107±3.667, and O.H. males: 69.59±22.76, while females had 62.083±8.013. The result of the study showed that across the age categories the males consistently had higher values of the facial parameters investigated. Conclusion: The result of the study showed that there was sexual dimorphism with the male values of all the facial dimensions measured were significantly higher than female values (P<0.05).
