The expected rise in temperature and decreased precipitation owing to climate change and unabated anthropogenic activities add complexity and uncertainty to agro-industry. The impact of soil nutrient imbalance, mismanaged use of chemicals, high temperature, flood or drought, soil salinity, and heavy metal pollutions, with regard to food security, is increasingly being explored worldwide. This review describes the role of soil-plant-microbe interactions along with organic manure in solving stressed agriculture problems. Beneficial microbes associated with plants are known to stimulate plant growth and enhance plant resistance to biotic （diseases） and abiotic （salinity, drought, pollutions, etc.） stresses. The plant growth-promoting rhizobemteria （PGPR） and mycorrhizae, a key component of soil microbiota, could play vital roles in the maintenance of plant fitness and soil health under stressed environments. The application of organic manure as a soil conditioner to stressed soils along with suitable microbial strains could further enhance the plant-microbe associations and increase the crop yield. A combination of plant, stress-tolerant microbe, and organic amendment represents the tripartite association to offer a favourable environment to the proliferation of beneficial rhizosphere microbes that in turn enhance the plant growth performance in disturbed agro-ecosystem. Agriculture land use patterns with the proper exploitation of plant-microbe associations, with compatible beneficial microbial agents, could be one of the most effective strategies in the management of the concerned agriculture lands owing to climate change resilience. However, the association of such microbes with plants for stressed agriculture management still needs to be explored in greater depth.

AIM： To study whether CCR5△32 mutation was associated with viral infection and severity of liver disease. METHODS： Two hundred and fifty two histologically proven, chronic HCV patients （mean age： 41±14 years; M/F： 164/88） were genotyped. PCR based genotyping of 32 bp deletion at the CCR5 locus was done. Fourhundred and eight matched healthy controls were studied to assess susceptibility to HCV infection. To assess correlation of immune gene polymorphism with severity of HCV related liver disease, patients with chronic HCV infection were divided into those with a fibrosis score of ≤ 2 （mild） or 〉 2 （severe） and histological activity index （HAI） of ≤ 5 or 〉 5. For correlation between CCR5△32 mutations and response to therapy, 129 patients who completed therapy were evaluated. RESULTS： The majority （89.4%） of the patients were infected with genotype 3. The frequency of homozygous CCR5△32 mutants was comparable to HCV patients as compared to the healthy controls （0.7% vs 0%, P = 0.1）. Further more, the frequency of CCR5△32 mutation was comparable in patients with mild or severe liver disease.（P = NS）. There was also no association observed with response to therapy and CCR5△32 mutation. CONCLUSION： CCR5△32 mutation does not have a role in disease susceptibility, severity or response to therapy in patients with chronic hepatitis C infection.

Impact of Variegated Temperature, CO<SUB>2</SUB>and Relative Humidity on Survival and Development of Beet Armyworm <i>Spodoptera exigua</i>(Hubner) under Controlled Growth Chamber

American Journal of Climate Change 2020年第4期9卷 357-370页

Climate change will have a noteworthy bearing on survival, development, and population dynamics of insect pests. Therefore, we contemplated the survival and development of beet army worm, Spodoptera exigua under different temperatures, (15°C, 25°C, 35°C, and 45°C), CO2 (350, 550, 750 ppm) and relative humidity (55%, 65%, 75% and 85%) regimes. Maximum larval and pupal weights were recorded in insects reared at 25°C. The growth of S. exigua was faster at 35°C (larval period 7.4 days and pupal period 4.5 days) than at lower temperatures. At 15°C, the larval period was extended for 61.4 days and there was no adult emergence from the pupae till 90 days. The S. exigua hatchling was absent at 45°C. The larval survival ranged from 31.6% - 57.2%, maximum survival was recorded at 25°C, and minimum at 45°C. The maximum (84.27%) and minimum adult emergence were recorded in insects reared at 25°C and 35°C respectively. Maximum fecundity (384.3 eggs/female) and egg viability (51.97%) were recorded in insects reared at 25°C. Larval and pupal periods increased with an increase in CO2 concentration. The highest pupal weights (128.6 mg/larva) were recorded at 550 ppm. The highest larval survival (73.50%) was recorded at 550 ppm and minimum (37.00%) at 750 ppm CO2. Fecundity was the highest in insects reared at 550 ppm CO2 (657.

“A Prospective Randomized Case-Control Study To Evaluate Mini Right Thoracotomy versus Conventional Sternotomy For Mitral Valve Repair In Rheumatic Heart Disease.”

World Journal of Cardiovascular Surgery 2016年第11期6卷 139-152页

作者： Ashok Kumar Chahal Preeti Gehlaut Sanjay Johar Ashish Asija Divya arora naveen Malhotra Kuldeep Singh Lallar Shamsher Singh Lohchab Department of Cardiac Surgery Pandit Bhagwat Dayal Sharma Post Graduate Institute of Medical Sciences Rohtak India Department of Anaesthesiology Pandit Bhagwat Dayal Sharma Post Graduate Institute of Medical Sciences Rohtak India Department of Cardiac Surgery Max Hospital Delhi India Department of Cardiology Pandit Bhagwat Dayal Sharma Post Graduate Institute of Medical Sciences Rohtak India

Purpose: Right mini thoracotomy has been evaluated in many studies for mitral valve repair mainly in degenerative valvular disease but not in rheumatic heart disease. Mitral valve repair is more challenging in rheumatic etiology due to complexity of lesions. This prospective randomized case control study was designed to evaluate repair through mini right thoracotomy and to compare the clinical and echocardiographic outcomes with sternotomy in rheumatic patients. Methods: 25 patients of rheumatic heart disease underwent mitral valve repair through mini right thoracotomy (group I). Various clinical and functional parameters were compared with 25 patients of mitral valve repair through sternotomy (group II). On follow up the results were compared in both groups for clinical and echocardiographic parameters. Results: The various pre-operative demographic parameters were comparable in two groups. Equal rate of mitral valve repair (group I-21/25, 84% and group II-21/25, 84%) was achieved in both groups. The various intra-operative and post-operative clinical parameters were better in group I .There were equivalent functional and valve related outcomes in both groups in term of NYHA class (1.28 ± 0.613 vs 1.08 ± 0.276, P = 0.144), post-operative mitral valve area (2.43 ± 0.891 vs 2.82 ± 0.662, P = 0.090), incidence of more than mild mitral regurgitation (0) and mean pressure gradient across mitral valve (4.98 ± 3.33 vs 4.23 ± 1.5, P = 0.309). Conclusion: Mitral valve repair through mini right thoracotomy approach in rheumatic etiology is feasible and safe with equivalent rate of successful repair as compared to median sternotomy. It is associated with lesser morbidity, cosmetic advantage and lesser resource utilization.
