ABSTRACT
The DSSAT CANEGRO model was calibrated and verified using field experimental data from five Tamil Nadu Agroclimatic Zones (1981-2022). The genetic coefficients of the sugarcane cultivar (CO-86032) were calculated. R2 obtained between measured and simulated stalk fresh mass was 0.9 with the nRMSE (0.01) and RMSE (1.6) and R2 between measured and simulated sucrose mass was 0.9 with the nRMSE (0.16) and RMSE (1.2). For yield R2 obtained between measured and simulated was 0.9 with the nRMSE (0.01) and RMSE (1.6). As a result, the CANEGRO model may be used to mimic the phenology and yield features of the sugarcane cultivar in Tamil Nadu's Agro Climatic Zones. Temperature increases in Agro Climatic Zones resulted in varying yield reductions, with 2 °C increases causing a 3% loss, 3 °C increases 5%, and 4 °C increases 9%. The Water Requirement rose throughout all of the ACZ due to the high temperature, but to differing degrees. A 2 °C increase often results in an average 4% increase in the WR. 3 °C rise in temperature increased WR to 9% and WR rose by 13% when the temperature was raised by 4 °C.
ABSTRACT
CYFRA21 - 1, a fragment of cytokeratin19, has been widely assessed as a serum marker of squamous malignancies. Previous studies using CYFRA21 - 1 and SCC-Antigen have shown mixed results but have indicated a better predictive prognostic value for SCC-Ag as compared to CYFRA21-1. The aim of our prospective, observational, pilot study was to evaluate the role of CYFRA21-1 and SCC-Ag in primary cervical carcinoma. Pre-operative serum CYFRA21-1 and SCC-Ag were measured (n = 14) in women with cervical carcinoma and correlated with staging, clinico-pathological parameters and prognostic data. Logistic regression analysis with CYFRA 21 - 1 test status (positive or negative) as a dependent variable showed that nodal metastases (p = 0.001) and lymphovascular space invasion (LVSI) (p = 0.005) were significant predictors, whereas stage and SCC-Ag levels were not significant. There was also no statistically significant correlation between SCC-Ag and CYFRA21-1 levels. If larger studies confirm these preliminary results, the option of laparoscopic surgical staging in patients with raised CYFRA21-1 levels could be considered.
