Stress-tension-pain occur more often in health disorders of women than anywhere in the entire spectrum of human illness. No where is the effect of rapid change more apparent than in the changing role of today's women who are subjected to pressures from all sides. Now a days women virtually take part occupy positions, in day to day activities similar to their male counterparts. An outline of conceptual consideration, biochemical overview of stress and intricacies of coping mechanisms are delineated from the point of view of stress situations in female (during reproductive life span) peculiar to them only viz menarche, menstrual cycle, pregnancy-eventualities of pregnancy-labour-delivery, purperium, postpartum psychosis, abortions-induced, spontaneous, menopause. Lipid profile and oxidative stress status as biochemical responses in these stresses were investigated. As expected observed maximal/minimal biochemical responses well correlated with peak time and at termination of stress. Present day emphasis is on menstrual regulation by intake of oral contraceptive to improve health if women prefer not to bleed every month and hormone replacement therapy for elderly women to improve post menopausal quality of life and avoiding menstrual problems at the same time. 相似文献

Course-based undergraduate research experiences (CUREs) may be a more inclusive entry point to scientific research than independent research experiences, and the implementation of CUREs at the introductory level may therefore be a way to improve the diversity of the scientific community.The U.S. scientific research community does not reflect America''s diversity. Hispanics, African Americans, and Native Americans made up 31% of the general population in 2010, but they represented only 18 and 7% of science, technology, engineering, and mathematics (STEM) bachelor''s and doctoral degrees, respectively, and 6% of STEM faculty members (National Science Foundation [NSF], 2013 ). Equity in the scientific research community is important for a variety of reasons; a diverse community of researchers can minimize the negative influence of bias in scientific reasoning, because people from different backgrounds approach a problem from different perspectives and can raise awareness regarding biases (Intemann, 2009 ). Additionally, by failing to be attentive to equity, we may exclude some of the best and brightest scientific minds and limit the pool of possible scientists (Intemann, 2009 ). Given this need for equity, how can our scientific research community become more inclusive?Current approaches to improving diversity in scientific research focus on graduating more STEM majors, but graduation with a STEM undergraduate degree alone is not sufficient for entry into graduate school. Undergraduate independent research experiences are becoming more or less a prerequisite for admission into graduate school and eventually a career in academia; a quick look at the recommendations for any of the top graduate programs in biology or science career–related websites state an expectation for undergraduate research and a perceived handicap if recommendation letters for graduate school do not include a discussion of the applicant''s research experience (Webb, 2007 ; Harvard University, 2013 ).Independent undergraduate research experiences have been shown to improve the retention of students in scientific research (National Research Council, 2003 ; Laursen et al., 2010 ; American Association for the Advancement of Science, 2011 ; Eagan et al., 2013 ). Participation in independent research experiences has been shown to increase interest in pursuing a PhD (Seymour et al., 2004 ; Russell et al., 2007 ) and seems to be particularly beneficial for students from historically underrepresented backgrounds (Villarejo et al., 2008 ; Jones et al., 2010 ; Espinosa, 2011 ; Hernandez et al., 2013 ). However, the limited number of undergraduate research opportunities available and the structure of how students are selected for these independent research lab positions exclude many students and can perpetuate inequities in the research community. In this essay, we highlight barriers faced by students interested in pursuing an undergraduate independent research experience and factors that impact how faculty members select students for these limited positions. We examine how bringing research experiences into the required course work for students could mitigate these issues and ultimately make research more inclusive. 相似文献

Informal environments provide students with unique experiences that allow them to actively participate in activities while promoting a positive attitude toward and an increased interest in science. One way to enhance informal science experiences is through the integration of mobile technologies. This integration is particularly useful in engaging underrepresented students in learning science. Our informal environmental science program engages underrepresented, fifth-grade students in an informal learning environment supplemented with mobile tablet technology (iPads). The purpose of this study was to explore how fifth-grade students interacted with nature using mobile technology during a nature hike series. Participants included 55 fifth-grade students from two low-income schools. We found that students used the mobile technology to explore nature and stay engaged throughout the hike. The iPads were used as references, data collectors, and engagement tools. Students had an intense desire in returning to the site and responded positively toward interacting with nature. Prior research has indicated that students in this age group are likely to lose interest in science and the incorporation of field-friendly technology that engages students with nature, not technology alone, is a useful tool for keeping students interested in science. 相似文献

Light chain disease is a variant of multiple myeloma in which the malignant population of marrow cells produces free monoclonal
light chains but no heavy chain or complete immunoglobulin. The monoclonal light chains are small enough to be freely filtered
by the kidneys and become Bence–Jones protein. Light chain disease comprises about 18% of multiple myeloma patients. Here
we present a case report of a 38-year-old man who initially presented with complaints of pain in back and low grade fever
off and on. He was found to have collapse of D9 and D12 vertebrae along with ascites and right pleural effusion and massive
proteinuria. Multiple myeloma was considered as a differential diagnosis based on the investigations but eventually the patient
was lost to follow up. This case is reported here as the light chain variant of multiple myeloma leading to deposition disease
is less commonly reported and presents considerable difficulties in diagnosis. 相似文献

The use of gamification to enhance learning in education has been well documented. However, little is known about whether gamification can impact supply chain management knowledge and behaviors among healthcare professionals. In this study, we tested the effectiveness of a simulation app (ShipShape) designed and developed to gamify the fundamental concepts of supply chain management. We field tested the effectiveness of the app to impact knowledge gain and supply chain practice by asking healthcare professionals to use the app in their day-to-day operations. We collected longitudinal data spanning the period before and after the introduction of the app. The analysis and results of different types of data collected provide support for the positive impact of the app on both supply chain knowledge and practice among healthcare professionals. 相似文献

This meta-analytic review of 148 studies on child and adolescent direct and indirect aggression examined the magnitude of gender differences, intercorrelations between forms, and associations with maladjustment. Results confirmed prior findings of gender differences (favoring boys) in direct aggression and trivial gender differences in indirect aggression. Results also indicated a substantial intercorrelation (r = .76) between these forms. Despite this high intercorrelation, the 2 forms showed unique associations with maladjustment: Direct aggression is more strongly related to externalizing problems, poor peer relations, and low prosocial behavior, and indirect aggression is related to internalizing problems and higher prosocial behavior. Moderation of these effect sizes by method of assessment, age, gender, and several additional variables were systematically investigated. 相似文献

ABSTRACTThis paper analyses how community, national and ethnic identities are affirmed, negotiated, marginalized as a part of hegemony-making and resistance in the context of English education in Indian universities. We argue and demonstrate that a complex and ambivalent hegemony that has been operational since the colonial times, continues to shape English education in India. Today, English and English education play a major role in articulating, binding and dividing multiple identities and knowledge systems. In the first part of the paper, we critically review debates and discussions on the significance of English language education in institutes of higher education in India. Specifically, we focus on discourses on the rationale behind continuing and contesting English education. The second part examines how in the postmodern context, English is being taught differently to different groups and highlights how these contexts of teaching have been defining knowledge systems, patterns of dominance and also, articulating resistance. 相似文献

Stereotype threat theory (STT) offers one explanation for achievement differences in math and science for both women and minority students. Specifically, STT posits that the perceived risk of confirming a negative stereotype about an individual’s identity group acts as a psychological burden that negatively impacts performance. This study examined the impact of stereotype threat (ST) on gender differences in chemistry achievement, self-efficacy, and test-anxiety using a four-group, quasi-experimental design. 153 introductory-level college chemistry students were randomly assigned to one of four ST conditions including an explicit ST condition, an implicit ST condition, a reverse ST condition, and a nullified condition. Results indicated that there were no gender differences by ST condition; however, overall, the men had higher self-efficacy and lower test-anxiety than the women. An analysis of open-ended questions asking students about their intent to major in chemistry, beliefs regarding barriers to their achievement on the chemistry test, and gender differences in opportunities and mental capacity to achieve in chemistry provided insight into the quantitative results. Implications of our findings for future research on ST are discussed. 相似文献

Mitochondrial diseases are a heterogeneous group of disorders in which a primary mitochondrial dysfunction is proven by morphological,
biochemical, and genetic examinations. The mitral valve has important function in the regulation of blood flow from one chamber
to another. Often, the mitral valve becomes abnormal with age, in Rheumatic fever or it is abnormal from birth (Congenital)
or it can be destroyed by infection i.e. bacterial endocarditis and needs replacement. Myocardial function depends on energy
produced by mitochondria and in any of these disease conditions, mitochondrial functions and enzyme activities may be impaired.
With this in view, we analyzed the relationship between preoperative clinical conditions (as per New York heart Association)
and extent of mitochondrial enzyme activities in damaged Human mitral valve in two types of heart disease such as Rheumatic
Heart Disease (RHD) and Bacterial Endocarditis (BE). Thirty nine Patients undergoing cardiopulmonary bypass (CPB) for routine
valvular heart surgery were included in the study. Controls included 11 normal porcine mitral valve samples without any evidence
of heart disease. Mitochondrial enzymes like cytochrome oxidase (COX), succinate dehydrogenase (SDH), malate dehydrogenase
(MDH), citrate synthase (CS) and ATPase were determined. Mitochondrial COX, SDH, CS and Total ATPase activities were significantly
decreased in disease condition like BE and RHD when compared with control (P<0.001). On the other hand as per New York Heart
Association (NYHA) preoperative clinical classification, all the mitochondrial enzymes were significantly (p<0.05) impaired
in class IV as compared with NYHA class I, II and III. Present study shows that impairment in the mitochondrial enzymes activities
are more pronounced in bacterial endocarditis (BE). It also indicates that damage to mitochondrial enzymes are most pronounced
in NYHA class IV. 相似文献
