Light scattering has been used for label-free cell detection. The angular light scattering patterns from the cells are unique to them based on the cell size, nucleus size, number of mitochondria, and cell surface roughness. The patterns collected from the cells can then be classified based on different image characteristics. We have also developed a machine learning (ML) method to classify these cell light scattering patterns. As a case study we have used this light scattering technique integrated with the machine learning to analyze staurosporine-treated SH-SY5Y neuroblastoma cells and compare them to non-treated control cells. Experimental results show that the ML technique can provide a classification accuracy (treated versus non-treated) of over 90%. The predicted percentage of the treated cells in a mixed solution is within 5% of the reference (ground-truth) value and the technique has the potential to be a viable method for real-time detection and diagnosis.  相似文献

Introduction

There is scarcity of data validating portable digital ankle-brachial index (ABI) with contrast angiography in peripheral arterial disease (PAD). Our aim was to provide an objective analysis of the relationship between digital ABI (dABI) and peripheral angiographic data.

Methods

Consecutive patients with symptoms of PAD between May 2014 to May 2015 at Einstein Medical Center, Philadelphia, who were undergoing simultaneous dABI and peripheral angiography, were evaluated. Measurements were made using the FloChec? Digital ABI system (Bard) prior to the scheduled peripheral angiogram.

Results

The final cohort consisted of 51 patients. Mean age was 68.8?±?9.5?years with 55% being male. Aorto-iliac disease accounted for 13% of the total lesions, while femoro-popliteal lesions comprised 55%. The FloChec? digital ABI had a sensitivity of 84% and a positive predictive value of 84%. The area under the receiver operating characteristic curve was 0.74 (p?=?0.007). On multivariate analysis, FloChec? digital ABI was still an independent predictor of PAD, Odds ratio 6.8 (2.3–20.6, p?=?0.001).

Conclusion

A portable, point-of-care digital ABI system can be used as a valuable, simple, cost-effective and reliable screening tool with high sensitivity and accuracy. To date, ours is the first study validating FloChec? digital ABI with the gold standard angiographic data.  相似文献

The authors studied the outcome of 108 infants <??6 mo with severe acute malnutrition (SAM) admitted in the Nutritional Rehabilitation Centres (NRC) at a teaching hospital. The most common symptom that the children presented with, was acute diarrhoea (35.2 %) followed by failure to gain weight (26.9 %). Seventy five (69.4 %) infants were cured after nutritional rehabilitation and 29 (26.8 %) were non responders. Fifty two (48 %) infants showed good weight gain after proper counseling or supplementary suckling technique alone.  相似文献
