This brief provides an insight into the present scenario of the role of nanotechnology in the diagnosis and treatment of lung cancer at an early stage. Currently, lung cancer is the subject of major concern owing to the very high mortality rate throughout the world. Most of the conventional treatment methods such as surgery, chemotherapy, radiotherapy, etc., fail to prolong life of the patients. Incidents of recurrence are also very common in case of lung cancer. Researchers have shown that nanoparticles may act as a powerful anti cancer tool, especially for lung cancer. Unique surface properties and easy surface functionalization of nanoparticles enable early detection, diagnosis, imaging and treatment of lung cancer. The authors have elaborately presented how various nanoparticles (natural, semi synthetic and synthetic) may help in the treatment of lung cancer. They have also detailed works of various scientists who succeeded in developing effective nanoparticles and enabled very specific lung cancer therapy without any undesirable side effects and minimized death.

The experiment was conducted to see the effect of spacing and poultry manure (PM) based integrated plant nutrient management in SRI method on the growth and yield of transplant aman rice. The experiment included three spacings viz. 25cm 15cm (conventional spacing), 30cm 30cm and 40cm 40cm, and seven PM based integrated fertilizer (NPKSZn) management viz. control i.e. without fertilizer, 100% NPKSZn i.e. recommended dose of fertilizer by BRRI 80, 26, 33, 11 and 2 kg/ha of N, P, K, S and Zn, respectively], 5 t/ha of PM, 50% NPKSZn+5 t/ha of PM, 50% NPKSZn+2.5 t/ha of PM, 75% NPKSZn+5 t/ha of PM and 75% NPKSZn+2.5 t/ha of PM were used. From this study it is found that both conventional spacing with 50% NPKSZn and 5 t/ha PM, and conventional spacing with BRRI recommended dose of fertilizer gives the highest grain yield. Based on the results obtained the best combination for the cultivation of BRRI dhan41 under SRI method during aman season was to use the conventional spacing 50% NPKSZn with 5 t/ha of PM to obtain the highest grain yield. Because it not only reduced the production cost but also had a long term impact on improvement of soil properties.
