Effect of pH on Isoliquiritigenin (ISL) fluorescence in lipo- polymeric system and metallic nanosystem.

Flavonoids have various medicinal properties such as anti-inflammatory, anti-oxidant, anti-cancer, antiviral. Yet, the fluorescent properties of flavonoids are less explored and termed as autofluorescence in general. This study investigates the fluorescence properties of Isoliquiritigenin (ISL) in various alkaline conditions.

Knowledge, attitude, and awareness of childhood cancer among undergraduate medical students in South India.

Background: In India roughly 60000 childhood cancer cases are diagnosed annually with only nearly 100 pediatric oncologists. So it's pertinent that the physicians and pediatricians are adequately equipped to recognize and refer them appropriately. Hence this study was conducted to assess the knowledge, attitude and awareness of childhood cancer among undergraduate medical students in South India.

Linear and neural models for classifying breast masses.

Computational methods can be used to provide an initial screening or a second opinion in medical settings and may improve the sensitivity and specificity of diagnoses. In the current study, linear discriminant models and artificial neural networks are trained to detect breast cancer in suspicious masses using radiographic features and patient age. Results on 139 suspicious breast masses (79 malignant, 60 benign, biopsy proven) indicate that a significant probability of detecting malignancies can be achieved at the risk of a small percentage of false positives.

An evolutionary algorithm that constructs recurrent neural networks.

Standard methods for simultaneously inducing the structure and weights of recurrent neural networks limit every task to an assumed class of architectures. Such a simplification is necessary since the interactions between network structure and function are not well understood. Evolutionary computations, which include genetic algorithms and evolutionary programming, are population-based search methods that have shown promise in many similarly complex tasks.
