Procalcitonin (PCT) is an innovative and highly specific marker for diagnosis of clinically relevant bacterial infection and sepsis. PCT supports early diagnosis and Clinical decision making. A retrospective study of two classical cases of neutropenic sepsis with elevated PCT levels in cardiac ICU was done. PCT was analyzed using Elecsys Brahms PCT kit. Serum PCT levels <0.5 ng/ml and ANC <1,000/mm3 was taken as cutoff. The first patient had initial high levels of PCT 100 ng/ml, TLC 13,600/mm3 and ANC 12,250/mm3. It was followed by drop with subsequent rise in PCT levels and drop in TLC 1,000/mm3 and ANC 70/mm3. The second patient had normal PCT 0.116 ng/ml, TLC 5,600/mm3 and ANC 4,420/mm3 levels followed with sharp increase in all the values with subsequent drop in TLC 2,000/mm3 and ANC 880 cells/mm3. Both the patients died of neutropenic sepsis with multiorgan failure. The case reports showed the correlation of PCT with TLC and ANC levels in predicting the mortality of patients with neutropenic sepsis in cardiac ICU. 相似文献

The main aim of this article is to extend the notion of strongly Cesàro summable and strongly lacunary summable real sequences to n-normed linear space valued (n-nls valued) difference sequences. Consequently we introduce the spaces |σ1|(X,?) and Nθ(X,?), respectively, where X is an n-normed space and ? is a difference operator. We investigate these spaces for completeness as well as for the relationship between these spaces. 相似文献

A 60-year-old patient suffering from easy fatigability was noted to have high total but normal conjugated bilirubin level though serum colour was pale. On further investigation the patient was found to be suffering from multiple myeloma and gamma globulin was possibly interfering with total bilirubin estimation. 相似文献

In this paper, emphasis has been put on providing the result of a detailed simulation study on the dynamics and efficiency of a vector-controlled voltage source inverter (VSI)-fed surface-mounted permanent magnet synchronous motor (SPMSM) drive; which employs firstly a model-based loss-minimization algorithm (MLMA) and secondly a binary search-based online loss-minimization algorithm (BSOLMA), so as to reduce the total controllable electrical losses without much affecting the dynamic performance of the drive. The steady-state SPMSM model taking into account the core loss has been considered. The dynamic performances of the SPMSM drive employing individually the abovementioned loss minimization algorithms (LMAs) have been compared with that employing conventional zero d-axis current control (ZDCC) through extensive digital computer simulations. The simulation results show that efficiency of the drive enhances with the employment of the LMA. 相似文献

The study was undertaken to evaluate the possible involvement of oxidative stress in the pathogenesis of ethanol induced testicular
atrophy in rats. Adult male rats were orally administered ethanol at a dose of 1.6 g/kg body weight/day for four weeks. Twenty-four
hours after the last treatment the rats were sacrificed using anesthetic ether. Testes were removed and weighed. Apoptosis
was studied by using the Feulgen reaction on 5 μ thin paraffin sections of testis. Testicular homogenate was prepared and
centrifuged. The supernatant was used for the estimation of extent of lipid peroxidation and antioxidant defense status. There
was significant reduction in body weight: and in testicular weight and diameter in ethanol treated rats. Extent of germ cell
apoptosis was significantly high in ethanol treated rats. Ethanol treated rats showed significantly high tissue TBARS level
and glutathione S-transferase activity; and low tissue ascorbic acid, reduced glutathione, superoxide dismutase, catalase,
glutathione peroxidase and glutathione reductase activities. Chronic ethanol administration resulted in high oxidative stress
in the testes either due to increased extent of lipid peroxidation or due to decreased antioxidant defenses, and thereby induces
germ cell apoptosis leading to testicular atrophy. 相似文献

Historically low average pass rate has been a perennial challenge for the universities and provincialised colleges in the North-Eastern states of India (Assam, Meghalaya, Mizoram, Nagaland, Tripura, Manipur and Arunachal Pradesh). Pass rate refers to the proportion of students promoted from one semester to the next and also the proportion of students who pass the final examination to be a graduate. The paper attempts to trace the key parameters for quality improvement for higher education in the region and subsequently augment the pass rate. An inductive content analysis was conducted based on focus group interviews at various levels at Assam University, Silchar and its affiliated provincialised colleges. The four broad categories thus identified (academic, administrative, socio-economic and placement issues) were subjected to Pareto 80-20 principle to identify the issues that are to be given priority for evolving the system. The study would help the administrators to measure the quality of higher education system in a hostile environment characterised by adverse topography, political disturbances, skewed distribution of income, widespread poverty and lack of literacy. 相似文献

Pathogens, especially Gram-negative bacteria or bacterial endotoxin, along with other classical factors, may be involved in
inflammatory response within the aortic endothelium during the progression of cardiovascular disease. Studies have shown that
bacterial endotoxin activates various inflammatory processes in the body. Our study aims to establish a correlation between
endotoxemia and vascular expression of antioxidant enzymes. Swiss albino mice (4 weeks old) were fed a high fat diet for 24
weeks and then were administered Escherichia coli endotoxin intraperitonealy, for 4 weeks. Tissue antioxidant enzymes, serum
levels of IL-6 and TNF alpha were measured from the mice. We report that i.p. administration of endotoxin to hyperlipidemic
mice resulted in elevation of superoxide dismutase and catalase enzymes, which was paralleled by a systemic reduction of serum
cholesterol and LDL expression. Myeloperoxidase levels were also found to be elevated in aortic tissue, while an increase
was also observed in the serum cytokine levels. 相似文献

ABSTRACT The essay explores the mobility of Whiteness in networks of Communication Studies that posture themselves as speaking from the Global South. Depoliticized languages of de-westernizing, internationalizing, and decolonizing are often articulated by elites in North-South networks pushing neoliberal governmentality, erasing claims to radical equality that emerge from within socialist struggles in the Global South. In resistance, a radical framework of knowledge from the Global South emerges from within subaltern struggles for hegemony, achieved through (a) delinking from the metropoles of the North and (b) explicitly crafting a socialist anticolonial politics that names and dismantles Whiteness as a capitalist project. 相似文献

Total plasma homocysteine was analysed in 64 cases of retinal vein occlusion (RVO) of which 24 cases of central retinal vein occlusion (CRVO) and 40 cases of branch retinal vein occlusion (BRVO) and compared with 45 age and sex matched control. Homocysteine was significantly increased in RVO cases in respect to control (P < 0.001). Analysis also revealed that prevalence of rise of plasma homocysteine was more in cases of CRVO (OR = 13) than that of BRVO (OR = 5.03). 相似文献

It is universally recognized that cadaveric dissection is an essential part of anatomy training. However, it has been reported to induce mental distress in some students and impair their intrinsic motivation (IM) to study. One of the postulated reasons for this behavior is the lack of adequate information and preparation of students for cadaveric dissection. Therefore, it is hypothesized that providing relevant information prior to cadaveric dissection will ameliorate the mental distress, enhance the IM of students, and improve their academic performance. A cohort of occupational therapy students enrolled in an anatomy course were psychologically prepared for cadaveric dissection. Students were provided with a curated list of YouTube videos and peer-reviewed journal articles related to cadaveric dissection prior to the commencement of the anatomy course. All students were also required to attend an oral presentation immediately before commencing dissection. The control group included students who had not been provided with any resources in preparation for cadaveric dissection. Compared to the control group, students who had been prepared demonstrated better quality of cadaveric dissection, improved academic performance, reported less mental distress and greater IM. Moreover, students reported the oral presentation to be most relevant and journal articles to be least useful in their preparation. Therefore, this is an effective approach in the amelioration of mental distress and improvement of performance in anatomy students. Consequently, this study represents a paradigm shift in the pedagogy of anatomy, and could represent a vital element in the evolution of a revitalized anatomy curriculum. 相似文献
