Groundwater Depletion and Role of Direct Seeded Rice in Water Saving: A Move Towards Sustainable Agriculture of Punjab

Presently, out of 20 million tube wells in the country, almost 1.3 million are in Punjab, contributing to fast-paced groundwater extraction and its depletion. Direct seeding of rice has a great potential for optimizing the water-use efficiency in paddy cultivation without any disturbing and harmful effect on its productivity, if weeds are controlled properly. A significant saving of 18 per cent was achieved for irrigating one hectare of the DSR farm in basmati and non-basmati varieties as compared to non-DSR farm. The mean overall technical efficiency was more in DSR farms as compared with non-DSR farms, with difference of about 12 per cent in basmati and 5 per cent in non-basmati fields. However, this difference was 7 per cent in basmati and 14 per cent in non basmati while calculating the average technical efficiency w. r. t water-use. Popularization of this technology among farmers in a participatory mode on a comprehensive scale needs a focused attention through capacity building of farmers

Service Level Agreement Aware SaaS Placement in Cloud

Cloud computing is an encouraging and favourable paradigm for both providers and consumers in diverse scopes of endeavors. Software as a Service (SaaS) is a method of conveying services or applications through the Internet – as a service, and it is known to be one of the very crucial computing services in cloud computing. Cloud computing has become a major medium for the SaaS providers to provide their applications because required scalability can be achieved through this. The challenges of SaaS placement process depends on various factors comprising cloud network size, resource requirements, and communication among its components. This thesis analyzes the SaaS Placement Problem (SPP) and proposes a mathematical model for SaaS placement in Cloud. This thesis gives an evolutionary approach, known as Particle Swarm Optimization (PSO) that has been applied to find the optimal placement of SaaS component and aiming to minimize the total cost incurred to the SaaS provider, and then evaluated against the traditional Greedy approach in experiments. The obtained results show our proposed algorithm SPPSO generates better solutions than Greedy approach SPGA

Bone metastasis in head and neck squamous cell carcinoma – 5-year experience of an Indian Cancer Institute

Introduction. Bone metastasis (BM), a common and awful complication of advanced malignancy, is comparatively infrequent in head and neck squamous cell carcinoma (HNSCC). Having a discouraging survival of around 6-months only, BM decreases the quality of life in such patients. We reported 13 cases of BM in HNSCC patients in respect to clinical patterns, treatment modalities and outcome. Material and methods. This is a retrospective study conducted in a tertiary cancer institute of India. Records of all HNSCC patients reviewed and patients having BM were identified. Results. Total 13 cases of BM were found over a 5-year period; 5 patients having synchronous BM and the rest had developed metastasis later. Monostotic and polyostotic diseases were found in 8 and 5 patients, respectively, bone exclusive disease was seen in 6 patients only. Overall median survival was 6.7 months. Conclusions. Palliation seems to be the only option once BM is diagnosed in HNSCC. All of our patients received local palliative radiation, and systemic chemotherapy to increase survival. As there is no standardized treatment for such occurrence, more case series and prospective studies are welcomed

Detection of Echovirus-18 in Children Suspected With SARS-CoV-2 Infection With Multisystem Inflammatory Syndrome: A Case Report From India

There have been several reports across the globe regarding the presentation of a severe multi-system hyperinflammatory syndrome, resembling Kawasaki disease (KD), in the pediatric population during the SARS-CoV-2 pandemic. The exact pathophysiology is still unclear; however, children typically demonstrate multi-organ dysfunction and less respiratory system involvement compared to adults. The limited literature is available at present for the identification and management of such patients. In this study, we investigated four cases in children ages 11–15 years that fulfilled the case definition for the pediatric multi-system inflammatory syndrome. All were found negative for SARS-CoV-2 from oropharyngeal swabs and stool. As they were having symptoms of diarrhea, tests for bacterial and enteric viral infections were performed after SARS-CoV-2 testing. Molecular analysis revealed that all the children were infected with enterovirus (Echovirus-18). Early and exact diagnosis is vital for timely, effective, and potentially life-saving management of such cases

A Scoping Review and Preliminary Illustrative Analysis of Biomarkers in Stress-Related Psychiatric Illness: Diagnostic and Prognostic Implications

Stress is the body's response to any changes that might place it under mental, emotional, or physical strain and could either demand attention or prompt action. A stress reaction can be brought on by both internal and external factors. The conditions, demands, issues, and expectations you deal with every day are all regarded as external influences, as are your physical surroundings, your job, your contacts with others, your family, and all other related factors. The ability of your body to respond to and handle external stimuli depends on internal factors. Your ability to handle stress is influenced internally by your food habits, level of general health and fitness, mental health, and the amount of sleep and rest you get. Such demanding conditions could affect how certain stress hormone levels are regulated. Biomarkers such as mGlu2/3, 5-hydroxyindoleacetic acid (5-HIAA), serum alpha-amylase, amygdala reactivity, neuropeptide Y (NPY), heat shock proteins, cortisol, and catecholamines are used to assess the hormone imbalance. Disease prevention, early detection, and therapy are all possible uses for biomarkers. In this review, we looked at a wide range of stress-related biomarkers that might cause different psychiatric illnesses and how those conditions can, over time, alter a person's lifestyle

A Prolific Solvate Former, Galunisertib, under the Pressure of Crystal Structure Prediction, Produces Ten Diverse Polymorphs

The solid form screening of galunisertib produced many solvates, prompting an extensive investigation into possible risks to the development of the favored monohydrate form. Inspired by crystal structure prediction, the search for neat polymorphs was expanded to an unusual range of experiments, including melt crystallization under pressure, to work around solvate formation and the thermal instability of the molecule. Ten polymorphs of galunisertib were found; however, the structure predicted to be the most stable has yet to be obtained. We present the crystal structures of all ten unsolvated polymorphs of galunisertib, showing how state-of-the-art characterization methods can be combined with emerging computational modeling techniques to produce a complete structure landscape and assess the risk of late-appearing, more stable polymorphs. The exceptional conformational polymorphism of this prolific solvate former invites further development of methods, computational and experimental, that are applicable to larger, flexible molecules with complex solid form landscapes

Honokiol Arrests Cell Cycle, Induces Apoptosis, and Potentiates the Cytotoxic Effect of Gemcitabine in Human Pancreatic Cancer Cells

Survival rates for patients with pancreatic cancer are extremely poor due to its asymptomatic progression to advanced and metastatic stage for which current therapies remain largely ineffective. Therefore, novel therapeutic agents and treatment approaches are desired to improve the clinical outcome. In this study, we determined the effects of honokiol, a biologically active constituent of oriental medicinal herb Magnolia officinalis/grandiflora, on two pancreatic cancer cell lines, MiaPaCa and Panc1, alone and in combination with the standard chemotherapeutic drug, gemcitabine. Honokiol exerted growth inhibitory effects on both the pancreatic cancer cell lines by causing cell cycle arrest at G1 phase and induction of apoptosis. At the molecular level, honokiol markedly decreased the expression of cyclins (D1 and E) and cyclin-dependent kinases (Cdk2 and Cdk4), and caused an increase in Cdk inhibitors, p21 and p27. Furthermore, honokiol treatment led to augmentation of Bax/Bcl-2 and Bax/Bcl-xL ratios to favor apoptosis in pancreatic cancer cells. These changes were accompanied by enhanced cytoplasmic accumulation of NF-κB with a concomitant decrease in nuclear fraction and reduced transcriptional activity of NF-κB responsive promoter. This was associated with decreased phosphorylation of inhibitor of kappa B alpha (IκB-α) causing its stabilization and thus increased cellular levels. Importantly, honokiol also potentiated the cytotoxic effects of gemcitabine, in part, by restricting the gemcitabine-induced nuclear accumulation of NF-κB in the treated pancreatic cancer cell lines. Altogether, these findings demonstrate, for the first time, the growth inhibitory effects of honokiol in pancreatic cancer and indicate its potential usefulness as a novel natural agent in prevention and therapy
