The Lung Mass and Nodule: A Case Series The Lung Mass and Nodule

Lung mass is an abnormal region of 3 cm or more in size present in the lungs mainly due to underlying pulmonary caner. It is usually round, opaque and poorly differentiated on X-ray. Common etiological key players are smoking, exposure to asbestos, radon, however, familial history may also play a role. We presented retrospectively7 cases of lung mass and nodule encountered during our clinical practice. We have discussed their clinical presentation, manifestation, medical history, radiological findings and differential diagnosis. In this case series, most of the patients were young, only 2 cases were older patients. There was one infant one month old, one female child 12 years old, one female 25 years, 2 males, 22 and 21 years, one male of 50 years and another male of 60 years age. Correct diagnosis on the basis of clinical profile, radiological findings and histology may help in proper management and hence, timely treatment of the patient

Synthesis of Polymer Nanomaterials and Their Analytical Applications

The preparation and properties of polymers are related to the conditions of synthesis and processing. The structural properties can easily be customized by strictly controlling such conditions. On the other hand, slight variation in some conditions may cause drastic variations in the characteristics of structure, and consequently properties. These conditions are the precursor concentrations, catalyst, time and temperature of curing. Herein we report facile and convenient syntheses of polymers with/without using surfactants and with/without using base or acid as a catalyst at low temperature. Polymers derived from 3-Aminophenol and formaldehyde, furfural alcohol was also used for the syntheses of polymers. These polymers were characterized by different techniques like SEM, EDX, XPS, TGA, FTIR, and Raman spectroscopy. These polymer spheres were converted into carbon spheres which show promising properties for supercapacitors. Later on these nano materials were used for the electrochemical detection of nitrite via cyclic voltammetry and Amperometry with the help of surface modified and carbon paste electrodes. These electrodes are highly selective and sensitive for estimation of nitrite. In addition to electrochemical, fluorogenic sensing of nitrite was also done which was also highly sensitive and selective towards nitrite.
