The proposed paper focuses on art as a form of cultural expression and it presents data based on ethnographic information of famous Pakistani musical theatres in Lahore, Province of Punjab. Most description of the performing arts is written by men with an exclusive male perspective. Little or no attempt has been made to explore women lives in performing theatre apart from their assigned role as physical crowd-pullers. This study presents how symbols are used to communicate, as each member of theatre community uses entire repertoire to convey messages, manual gesticulations, body gestures, facial expressions, dance patterns, a particular dress etc. at the cultural level. The central idea of this study is how artists use the body in performance to imagine and enact culture, values, humor, selfhood, and the complex relations among them. It discusses their real backstage life experiences and problems faced as well how and what type of contact they maintain with their audience and admirers. What are their moral values and what kind of social dilemmas they face, how the sexuality of theatre women is being controlled, their fears emotions, distress of theatre women etc. are the major research questions. In short, this anthropological inquiry takes into account all relevant social, cultural, political, economic, and religious dimensions of performing art.

目的:探讨正电子发射断层扫描/磁共振成像-弥散加权成像(PET/MRI-DWI)在子宫内膜癌分期中的临床应用潜力。方法:本研究共纳入50例治疗前接受PET(PET/计算机断层扫描[CT])、PET/MRI-DWI、MRI-DWI检查的子宫内膜癌患者。随访的影像学和组织病理学结果作为金标准。以病理分期为金标准,采用Kappa一致性检验对三个分期的诊断一致性进行评价。采用χ检验比较三个分期的诊断差异。采用Wilcoxon秩和检验比较PET/MRI-DWI、PET(PET/CT)、MR-DWI在分期、肌层浸润深度、宫颈浸润、淋巴结转移等方面的诊断可信度差异。采用受试者工作特征(ROC)曲线分析三种影像学方法对肌层浸润深度、宫颈浸润、淋巴结转移的诊断效能。采用De Long检验比较ROC曲线下面积。结果:PET(PET/CT)、MRI-DWI、PET/MRI-DWI分期与金标准诊断一致性高。PET/MRI-DWI与PET/CT、PET/MRI-DWI与MRI-DWI在子宫内膜癌的分期和诊断可靠性方面存在统计学差异。PET/MRI-DWI对肌层浸润深度的诊断效能和可靠性优于PET/CT,但与MRI-DWI无差异。三种影像技术对宫颈浸润的诊断差异无统计学意义,但PET/MRI-DWI具有较高的诊断可靠性。PET/MRI-DWI对淋巴结转移的诊断效能和可靠性均显著优于MRI-DWI,但与PET/CT无显著差异。结论:MRI-DWI对子宫内膜癌的早期(I期)分期较好。PET/CT更适合晚期(II期和III期)分期。PET/MRI-DWI对早期和晚期分期都有优势,推荐用于子宫内膜癌的临床分期。

Interleukin-1α (IL-1α) is a proinflammatory cytokine that has also been found to act as a paracrine mediator involved in the regulation of testicular functions. The present review provides an overview of the role of IL 1α in testicular physiology. Bioactive IL-1α isolated from adult rat testis was found to consist of three distinct immunoreactive protein species with apparent sizes of 45, 24 and 19 kDa. These isoforms showed bioactivity in a thymocyte proliferation and steroidogenesis assays with different biopotencies. The background of the molecular heterogeneity and processing, secretion and regulation of the isoforms of testicular IL-1α are discussed. All three isoforms have been found to be secreted into the testis tubular lumen and interstitial space. We have provided evidence that IL-1α is a paracrine factor that may be of importance in, e.g., the regulation of Leydig cell steroidogenesis. Pathophysiologically, testicular IL-1α may contribute to testicular relapse of acute lymphocytic leukemia in boys.

Background: Gynaecological malignancies are the second most common cancer of females after cancer breast. Gynaecological malignancies contribute significantly to cancer burden and have a higher rate of mortality and morbidity. Carcinoma cervix is the commonest gynaecological malignancy in developing countries while in developed countries, ovarian cancer is the commonest. Comprehensive statistics on gynecologic malignancies reported from Bangladesh are deficient. This study was performed to ascertain the profile of gynecologic cancers reported at our center regarding demography, the frequency of involvement at various sites, clinical presentation, incidence, histologic subtypes and stage at presentation. Methods: This is a retrospective study where the records of the Departments of Gynecology and Pathology at Enam Medical College & Hospital, Dhaka, Bangladesh were retrospectively reviewed to identify all cases of Gynecologic malignancies and to determine the pattern of gynaecological malignancies identified between January 2015 and December, 2018. Results: Cervical cancer (53%) was the most common gynaecological malignancy, followed by ovarian cancer (29%), uterine cancer (8%), vulvar cancer (5%) and gestational trophoblastic neoplasm (GTN 5%). In the case of cervical and ovarian cancer the most common age group was 41 - 50 years and gestational trophoblastic neoplasm (GTN). The majority of patients presented at the ages of 31 - 40 years while uterine cancer presented in the elderly (>60 years). Among the patients studied 88% were multiparous. Of the cervical cancer cases, 96.22% was squamous cell carcinoma and commonest presenting complains were contact bleeding (33.96%) and excessive and irregular menstruation (26.41%). Among ovarian tumor cases 69% had epithelial while 31% had non-epithelial cancer and predo&

In order to control traffic congestion, many mathematical models have been used for several decades. In this paper, we study diffusion-type traffic flow model based on exponential velocity density relation, which provides a non-linear second-order parabolic partial differential equation. The analytical solution of the diffusion-type traffic flow model is very complicated to approximate the initial density of the Cauchy problem as a function of x from given data and it may cause a huge error. For the complexity of the analytical solution, the numerical solution is performed by implementing an explicit upwind, explicitly centered, and second-order Lax-Wendroff scheme for the numerical solution. From the comparison of relative error among these three schemes, it is observed that Lax-Wendroff scheme gives less error than the explicit upwind and explicit centered difference scheme. The numerical, analytical analysis and comparative result discussion bring out the fact that the Lax-Wendroff scheme with exponential velocity-density relation of diffusion type traffic flow model is suitable for the congested area and shows a better fit in traffic-congested regions.
