| Abstract | Alpha-1-antitrypsin deficiency (AATD) and tobacco smoke play a key role in the pathogenesis of early-onset emphysema. Differences in AATD-related chronic obstructive pulmonary disease stages imply the existence of modifying factors associated with disease severity. We present two male patients with emphysema caused by severe AATD (PiZZ genotype). Both are former smokers and have epoxide hydrolase low-activity phenotype. Extremely high level of oxidative stress (high urinary 8-oxo-7,8-dihydro-2′-deoxyguanosine), increased inflammation (high serum CRP), and GSTP1 105Val mutation were found in patient with a worse lung function and prognosis. These data provide more evidence that oxidative stress-related gene variants and inflammation are associated with worse symptoms of AATD-related emphysema. Therefore, prevention against severe stage of AATD-related emphysema would include early identification of the risk gene variants, cessation or never smoking, and treatment with anti-inflammatory and anti-oxidant drugs. Additionally, urinary 8-oxodG could be a candidate for predictive biomarker for routine assessment of the oxidative stress level in AATD patients. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
