Performance of no-till maize under drip-fertigation in a double cropping system in semi arid Telangana state of India

Availability of water for Agriculture is becoming increasingly difficult, besides the cost of power for applying it. Improving the water and nitrogen use efficiency has become imperative in present day’s Agriculture. Drip irrigation and fertigation provides the efficient use of limited water with increased water and nutrient use efficiency, respec- tively. A field experiment was conducted during post rainy season of two consecutive years (2011 and 2012), in sandy loam soils of Warangal, Telangana State, India to study the response of no-till maize (Zea mays L) after aerobic rice (Oryza sativa L) to drip irrigation and nitrogen fertigation under semi-arid environment. The experiment was laid out in split plot design with four replications. Three irrigation schedules viz. drip irrigation at 75% Pan Evaporation (PE); 100% PE and 125% PE were taken as main plots and three nitrogen levels through fertigation viz. 120, 160, and 200 kg ha-1 as sub plots. The growth parameters (plant height, LAI, drymatter accumulation), root volume and dry weight, yield attributes (cobs plant-1, kernels cob-1, kernel weight cob-1) kernel yield, stover yield and nitrogen uptake of no till maize increased with increase in water input from 75% PE to 100% PE irrigation schedule in drip irrigation but could not reach the level of significance at 125% PE. Tasseling and silking was hastened in 125% PE schedule. Increase in the level of N application through fertigation from 120 to 160 kg N ha-1 resulted in the increase of all the growth parameters, yield attributes, kernel yield, stover yield and nitrogen uptake. Barrenness and test weight were unaffected by either the irrigation schedules or nitrogen levels. The economic indicators (gross returns, net returns and net benefit: cost ratio) were higher with the irrigation schedule of 125% PE and nitrogen dose of 200 kg N ha-1 applied through fertigation. Increased water input from 75 to 125% PE resulted in decreased water use efficiency but enhanced nitrogen use efficiency while the reverse trend was found with respect to N levels under fertigation

Evaluation of the clinicoradiological profile in cases of allergic bronchopulmonary aspergillosis: An original research

Introduction: A complicated hypersensitive reaction to inhaled fungal antigens results in allergic bronchopulmonary aspergillosis (ABPA), an immunologic pulmonary disease. ABPA complicates nearly 2% of instances of persistent asthma as well as nearly 10% of chronic cases of steroid-dependent asthma, and it occurs most frequently in immunocompetent patients. The purpose of the current research was to analyze the radiological and clinical features of the participants as well as the serological association of ABPA. Materials and Methods: From April 2020 to April 2021, a retrospective investigation was conducted. The study included patients based on the International Society for Human and Animal Mycology's criteria for ABPA confirmation. Analysis was done on the demographic information and pathological and radiological test results of the patients. The patients' pre-bronchodilator and post-bronchodilator spirometry was compared, and asthmatic control was estimated. Results: A total of 50 patients were investigated at in this study. Demographic findings indicated young subjects and aa female predominance. Cough was the most prevalent symptom in 84% of patients. Asthma of the bronchi was a risk factor for all of the patients. The mean serum immunoglobulin E level and the mean absolute eosinophil count were 533 cells/L and 2269 UI/mL, respectively. Spirometry results from the study's participants indicated an obstructive pattern in about 80% of cases. The most typical radiological abnormality observed was bronchiectasis, followed by parenchymal opacities. Conclusion: In conclusion, when treating asthma that is challenging to control, the diagnosis of ABPA must be taken into account. Delay in diagnosis might result in declining lung function, worsening asthma control, possibly irreversible alterations, greater treatment costs, and declined quality of life

Carbazole–pyrrolo[2,1-c][1,4]benzodiazepine conjugates: design, synthesis, and biological evaluation

A series of carbazole–pyrrolobenzodiazepine conjugates (4a–g and 5a–f) have been designed, and synthesized as anticancer agents. These compounds are prepared by linking the C8-position of DC-81 with a carbazole moiety through simple alkane spacers as well as piperazine side-armed alkane spacers in good yields. The DNA binding ability of these conjugates has been determined by thermal denaturation studies and also supported by molecular docking studies. These conjugates showed potent anticancer activity with GI50 ranging from 5.27–0.01 μM. The FACS analysis and BrdU assay of selected conjugates (4c, 4f, 5a and 5f) on MCF-7 cell lines disclosed the increased G1 cell cycle arrest and one of the conjugates 5f has exhibited significant anticancer activity. The analysis of the intrinsic factors involved in causing the G1 arrest in MCF-7 cell lines by 5f conjugate has been demonstrated on the proteins which play a vital role in G1 arrest followed by apoptosis (Cyclin D1, CDK4, c-Jun, JunB, CREB, p53, JNK1/2, procaspase-7, cleaved PARP, pRb, and BAX). Thus, these PBD conjugates (in particular 5f) have promising potency for combating human carcinoma
