The Prediction in Ungauged Basins (PUB) initiative of the International Association of Hydrological Sciences (IAHS), launched in 2003 and concluded by the PUB Symposium 2012 held in Delft (23–25 ...October 2012), set out to shift the scientific culture of hydrology towards improved scientific understanding of hydrological processes, as well as associated uncertainties and the development of models with increasing realism and predictive power. This paper reviews the work that has been done under the six science themes of the PUB Decade and outlines the challenges ahead for the hydrological sciences community. Editor D.

One of the most frequent solid tumors in children is neuroblastoma, which has a variety of clinical behaviors that are mostly influenced by the biology of the tumor. Unique characteristics of ...neuroblastoma includes its early age of onset, its propensity for spontaneous tumor regression in newborns, and its high prevalence of metastatic disease at diagnosis in individuals older than 1 year of age. Immunotherapeutic techniques have been added to the previously enlisted chemotherapeutic treatments as therapeutic choices. A groundbreaking new treatment for hematological malignancies is adoptive cell therapy, specifically chimeric antigen receptor (CAR) T cell therapy. However, due to the immunosuppressive nature of the tumor microenvironment (TME) of neuroblastoma tumor, this treatment approach faces difficulties. Numerous tumor-associated genes and antigens, including the MYCN proto-oncogene (MYCN) and disialoganglioside (GD2) surface antigen, have been found by the molecular analysis of neuroblastoma cells. The MYCN gene and GD2 are two of the most useful immunotherapy findings for neuroblastoma. The tumor cells devise numerous methods to evade immune identification or modify the activity of immune cells. In addition to addressing the difficulties and potential advancements of immunotherapies for neuroblastoma, this review attempts to identify important immunological actors and biological pathways involved in the dynamic interaction between the TME and immune system.
Introduction: Coronavirus disease 2019 (COVID-19) has resulted in significant morbidity and mortality worldwide. The pre-immunosuppressed state along with other existing co-morbidities can influence ...the outcomes of COVID-19 in transplant patients Material and Methods: This was a single centre prospective cohort study done in kidney transplant recipients (KTRs), who underwent kidney transplantation (from December 2012 to November 2020), who were actively followed up at our centre and were diagnosed with COVID-19 disease between 1 April and 30 November 2020. Results: A total of 62 kidney-transplant recipients tested positive for COVID-19. Their median age was 39 (19-61). Males were predominantly infected (87.1%). Fever was the most common symptom (77.42%). Thirteen (20.9%) had mild form of disease, 32 (51.6%) had moderate form and 17 (27.4%) had severe disease. Based on initial symptom, 18 (29.03%) were given home treatment, 29 (46.7%) were treated in isolation wards and 15 (24.1%) were treated in intensive care unit. Decrease in the dose of immunosuppressant (anti-metabolites in 67.7%, calcineurin inhibitor in 22.5%) was predominantly carried out as the initial mode of treatment. Remdesivir in 64.5% and anticoagulant therapy in 54.84% were given as a modality of treatment. Mortality rate in our study was 14.5%. Conclusions: Patients of kidney transplant are at high risk of getting infected with COVID-19, due to their immunosuppressed state. Initial symptoms in KTRs with COVID-19 are similar to that of the general population. Mortality rate is comparatively higher in KTRs as compared to general population.
Observing system simulation experiments were used to investigate ensemble Bayesian state-updating data assimilation of observations of leaf area index (LAI) and soil moisture (θ) for the purpose of ...improving single-season wheat yield estimates with the Decision Support System for Agrotechnology Transfer (DSSAT) CropSim-Ceres model. Assimilation was conducted in an energy-limited environment and a water-limited environment. Modeling uncertainty was prescribed to weather inputs, soil parameters and initial conditions, and cultivar parameters and through perturbations to model state transition equations. The ensemble Kalman filter and the sequential importance resampling filter were tested for the ability to attenuate effects of these types of uncertainty on yield estimates. LAI andθobservations were synthesized according to characteristics of existing remote sensing data, and effects of observation error were tested. Results indicate that the potential for assimilation to improve end-of-season yield estimates is low. Limitations are due to a lack of root zone soil moisture information, error in LAI observations, and a lack of correlation between leaf and grain growth.
Soil organic matter (SOM) contributes to the productivity and physical properties of soils. Although crop productivity is sustained mainly through the application of organic manure in the Indian ...Himalayas, no information is available on the effects of long-term manure addition along with mineral fertilizers on C sequestration and the contribution of total C input towards soil organic C (SOC) storage. We analyzed results of a long-term experiment, initiated in 1973 on a sandy loam soil under rainfed conditions to determine the influence of different combinations of NPK fertilizer and fertilizer

To determine the cold tolerance and plant growth promotion potential of Serratia marcescens strain SRM (MTCC 8708). Serratia marcescens strain SRM was isolated from the flowers of summer squash ...plants, showing no apparent symptoms of yellow vine disease. It was evaluated for growth and plant growth promotion attributes at 15 and 4°C. At 15°C, the isolate was able to solubilize 76·6 μg ml⁻¹ of P and produce Indole Acetic Acid, IAA (11·1 μg ml⁻¹). HCN and siderophore production were also detected at 15°C. The isolate retained all the plant growth promotion traits at 4°C. Seed bacterization with the isolate significantly enhanced plant biomass and nutrient uptake of wheat seedlings grown in cold temperatures. Serratia marcescens strain SRM is a promising cold-tolerant isolate that can significantly influence wheat seedling growth at cold temperatures. This strain can be employed as a bioinoculant in cold temperature conditions.
