Now a days measurement of molecular forms of PSA has gained importance in clinical practice. Several studies have demonstrated
the production of PSA in female tissues, such as breast. The present piece of work has been undertaken with an objective to
estimate the relative proportion of the molecular forms of PSA in serum along with serum testosterone in benign and malignant
breast tumor cases and to analyze their association with the severity of the disease process 34 malignant and 26 benign breast
disease cases along with 33 healthy controls of same age group were enrolled in this study for evaluation. Serum testosterone
was measured by ELISA, whereas serum total PSA (TPSA) and free PSA (FPSA) were estimated by electrochemiluminescence immunoassay.
A significant rise of fasting plasma glucose along with prominent dyslipidemia was observed in breast tumor cases. Marked
rise in serum testosterone as well as TPSA and FPSA was documented in both benign and malignant breast tumor cases. Serum
testosterone revealed a significant positive association with both TPSA and FPSA pointing towards an etiological association
between them. However, surgical removal of tumor mass resulted in a marked decline of presurgical value of both TPSA and FPSA
with a non-significant fall in serum testosterone revealing tumor tissue as the source of FPSA and TPSA. Thus, estimation
of PSA provides prognostic information that may assist in future treatment. 相似文献

The rate of glucose consumption and pyruvate and lactate production in red blood cells of normal, sickle cell trait and SS disease subjects were measured. Glucose consumption was found to be increased significantly (p<0.05) in red cells of sickle cell patients than the sickle cell trait and normal persons. There was also an increased rate (p<0.05) of pyruvate formation and a significant (p<0.05) increase in lactate formation in sickle red cells. 相似文献

This paper proposes to use a hybrid Stochastic Fractal Search (SFS) and Local Unimodal Sampling (LUS) based multistage Proportional Integral Derivative (PID) controller consisting of Proportional Derivative controller with derivative Filter (PDF) plus (1 + Proportional Integral) for Automatic Generation Control (AGC) of power systems. Initially, a single area multi-source power system consisting of thermal hydro and gas power plants is considered and parameters of Integral (I) controller is optimized by Stochastic Fractal Search (SFS) algorithm. The superiority of SFS algorithm over some recently proposed approaches such as optimal control, Differential Evolution (DE) and Teaching Learning Based Optimization (TLBO) is demonstrated. To improve the system performance further, LUS is subsequently employed. The study is further extended for different controllers like PID, and proposed multistage PID controller and the superiority of multistage PID controller over conventional PID controller structure is demonstrated. The study is further extended to a two-area six unit multi-source interconnected power system and the superiority of proposed approach over, TLBO and optimal control is demonstrated. Finally the study is extended to a three unequal area system power system with appropriate nonlinearities such as Generation Rate Constraint (GRC), Governor Dead Band (GDB) and time delay. From the analysis, it is found that hybrid SFS–LUS algorithm is superior to the original SFS algorithm and substantial improvement in system performance are realized with proposed multistage PID controller over conventional PID controller structure. 相似文献

Online professional development (OPD) has potential to improve teacher quality by improving teachers' knowledge and instructional practices. These changes, in turn, have potential to improve student achievement. Unfortunately, there is a dearth of scientific research on the effects of OPD on teachers and, more importantly, on students. This article presents the results of a randomized controlled trial exploring the effects of a series of three learning-community model OPD workshops on teachers' content knowledge, teachers' instructional practices, students' content knowledge, and students' practices in the context of seventh-grade English language arts. There were statistically significant effects on teachers' vocabulary and overall English language arts content knowledge and on vocabulary and writing practices. The effect sizes of these changes ranged from small to medium. There were statistically significant effects on students' reading comprehension practices. 相似文献

Multiple myeloma is a group of B-cell disorders resulting in the secretion of a specific and unique monoclonal immunoglobulin
(M-protein). Protein electrophoresis is advised whenever multiple myeloma is suspected. The monoclonal protein migrates as
a single entity in the electric field and is detected by the non-specific protein stain as a more intensely stained band superimposed
on the usual protein pattern. The M-protein usually migrates in the gamma or beta region of the normal protein pattern; very
rarely it may appear in the α2 or even in α1 region. Here we have given an atypical case presentation where the patient with
multiple myeloma presented with two M-spike one each in α2 and β-globulin region on agarose gel protein electrophoresis with
hypoglobulinemia but with reversed A:G ratio. 相似文献

This article addresses the issue of Caribbean cultural under‐representation in school art departments. It argues that diasporic subjects are not seen and their cultures not recognised precisely because their contributions to the way we live are indivisible from the mainstream. This in contradistinction to some groups whose cultures and heritages are relatively distinct and separate from Western mores. Our ways of understanding culture do not take this into account. Yet diasporic contributions to the way we live have buttressed Western lifestyles since the beginning of the slave trade. The article argues that this relationship, characterised by multiple entanglements, must be recognised if Caribbean cultural identities are to be seen and valued. In doing so it challenges the way we construct notions of cultural heritage and belonging, and promotes the adoption of more risk‐taking pedagogies possibly based on contemporary practices. 相似文献

The Education Departments of Tate Modern and Goldsmiths College collaborated with a group of teachers to find out what they understood by the term ‘contemporary art’ and to discover the conditions that enable contemporary art practices in the classroom. We explored questions with eleven teachers, from both primary and secondary schools, during the Autumn of 2004. Although the cultural/ethnic context of the schools the teachers worked within was diverse, they shared a commitment to working with contemporary art in the classroom and exploring new pedagogies in this field. Their engagement with contemporary art and their revealing and compelling experiences are documented, contextualized and summarized. Samples of the discussions form the substance of this article. This is preceded by an analysis of the success of socially‐orientated contemporary art in the wider global context and its contrast with the omission of these practices in many schools. Conclusions have been tentatively drawn about how the curriculum may be better served by the use of contemporary art, as well as the means by which new learning methods may be facilitated. 相似文献

This article looks at the concept of Black History Month and its implications for teaching and learning in art and design education. It argues that the concept of Black History Month should be discarded because it tends to promote a separatist notion of culture and that it deflects from an understanding of culture as a plural and intermeshing process. The paper interrogates history as a discourse, problematising our use of the word. The article then looks through the eyes of two groups of African Caribbean young people at Black History Month, as a curriculum initiative. The first group was interviewed at a south London gallery and the second at a conference for African Caribbean learners in Oxford. Two art and design educationalists who participated in the research project that included the south London young people make a significant contribution to the paper. It concludes with a personal interpretation of movements in art and the practice of a contemporary artist whose work endorse the key philosophical position posited in the text that culture is always a process on interweaving. 相似文献

Total thiol status of plasma, especially thiol groups over protein contributes maximum to the plasma antioxidant status of
the body. Serum protein thiols were found to be decreased in various disease conditions including chronic renal failure patients.
Only few studies determined the levels of urinary protein thiols in disease conditions. The current study was designed to
know the levels of urinary protein thiols in patients with different grades of proteinuria. The study was conducted on urine
of 40 healthy controls and 61 cases with proteinuria. Based on proteinuria cases were further divided into two groups; group
I - microproteinuria (150–300 mg protein/d), 32 cases, group II - frank proteinuria (>300 mg protein/d), 29 cases. Urinary
thiol levels were determined by spectrophotometric method using dithionitrobenzoic acid. A significant decrease (p<0.01) in
urinary thiol in group I and group II cases was observed in present study and this decrease was associated with proteinuria. 相似文献
