In Raman spectroscopy, inelastic scattering of photons from an atomor molecule in chemical entities is utilized to analyze
the composition of solids, liquids and gases. However, the low cross-section limits its applications. The introduction of
surface-enhancedRamanspectroscopy in 1974has attracteda lot of attention fromresearchers due to the large enhancement of weak
Raman signal,which facilitates identification in chemical and biological systems. Recently, single-molecule Raman scattering
has enhanced the detection sensitivity limit of Raman Spectroscopy. 相似文献

This study is carried out to determine the prevalence of metabolic syndrome (MS) in 148 women between 36 to 65 years using the International Diabetes Federation criteria in the North-Eastern part of India. The prevalence of MS and all its individual components were found to be significantly higher among postmenopausal as compared to premenopausal and perimenopausal women. Various components of MS except waist circumference shows a significant increase and homeostasis model assessment index for insulin resistance also showed significant differences between the three groups. All the MS diagnostic markers (except serum high density lipoprotein) showed a strong positive correlation with MS score among the groups. Further MS score correlated with indicators of insulin resistance evaluated. This study concluded that MS is highly prevalent among North-East Indian postmenopausal women seeking primary health care and its determinant factors related to age and sedentary habits. Thus recognizing and treating MS early with proper intervention can minimize complication. 相似文献

Organoids are biological systems grown in vitro and are observed to self-organize into 3D cellular tissues of specific organs. Brain organoids have emerged as valuable models for the study of human brain development in health and disease. Researchers are now in need of improved culturing and imaging tools to capture the in vitro dynamics of development processes in the brain. Here, we describe the design of a microfluidic chip and bioreactor, to enable in situ tracking and imaging of brain organoids on-chip. The low-cost 3D printed microfluidic bioreactor supports organoid growth and provides an optimal imaging chamber for live-organoid imaging, with drug delivery support. This fully isolated design of a live-cell imaging and culturing platform enables long-term live-imaging of the intact live brain organoids as it grows. We can thus analyze their self-organization in a controlled environment with high temporal and spatial resolution. 相似文献

It has been proposed that sensitivity to the parameters underlying speech rhythm may be important in setting up well-specified
phonological representations in the mental lexicon. However, different acoustic parameters may contribute differentially to
rhythm and stress in different languages. Here we contrast sensitivity to one such cue, amplitude envelope onset (rise time),
in dyslexic and normally-developing children in two languages, Hungarian and English, ages from 7 to 11. Dyslexic and control
children received phonological tasks, reading and spelling tasks and auditory processing tasks. While sensitivity to rise
time was related to phonological representation in both languages, clear differences were found between languages. It is suggested
that these differences may reflect differential language-specific weighting of different acoustic cues to rhythm and stress.

The use of technology to facilitate education and the provision of an entire higher education degree has exploded in the last two decades. Social work educators have been a part of that trend and have started to utilize distance education (DE) technologies. There is a growing literature regarding the efficacy of DE instruction in social work, and scholars are actively developing best practices. However, there is little research in general to support the cost of DE, no cost studies in social work, and none comparing costs of DE delivery to costs associated with a face-to-face program. This study hopes to fill this gap by providing an analysis of the direct costs of an MSW DE program in comparison to similar costs of a face-to-face program. 相似文献
