Hydroponics, a soil-less agriculture system, consumes less water and resources compared to traditional soil-based farming. However, it requires simultaneous monitoring of various parameters, making it challenging. This article explores a ground-breaking hydroponic system designed to revolutionize modern farming by creating a precision-controlled environment for plant growth. Our research developed a Smart Hydroponic farm using Internet of Things (IoT) technology to highlight its advantages over traditional humanintervened hydroponics. Given the high costs of organic farming, this paper offers a more feasible solution through automated hydroponics with remote monitoring and control. The system exemplifies smart agriculture by utilizing real-time sensors for light, pH, EC, temperature, water level, and a camera module, all managed by a Raspberry Pi processor. It aims to save labor and resources while providing precise control over watering and fertilization. The primary function of this hydroponic system is to automate parameter monitoring and control via actuators, facilitating faster production of green leafy vegetables and eliminating the labor-intensive tasks typically associated with farming.

Germ cell tumors (GCTs) are the most common cancer in men between the ages of 15 and 40. Although most patients are cured, those with disease arising in the mediastinum have distinctly poor outcomes. One in every 17 patients with primary mediastinal nonseminomatous GCTs develop an incurable hematologic malignancy and prior data intriguingly suggest a clonal relationship exists between hematologic malignancies and GCTs in these cases. To date, however, the precise clonal relationship between GCTs and the diverse additional somatic malignancies arising in such individuals have not been determined. Here, we traced the clonal evolution and characterized the genetic features of each neoplasm from a cohort of 15 patients with GCTs and associated hematologic malignancies. We discovered that GCTs and hematologic malignancies developing in such individuals evolved from a common shared precursor, nearly all of which harbored allelically imbalanced p53 and/or RAS pathway mutations. Hematologic malignancies arising in this setting genetically resembled mediastinal GCTs rather than de novo myeloid neoplasms. Our findings argue that this scenario represents a unique clinical syndrome, distinct from de novo GCTs or hematologic malignancies, initiated by an ancestral precursor that gives rise to the parallel evolution of GCTs and blood cancers in these patients., Introduction Germ cell tumors (GCTs) are a model of curable cancer, as most patients with metastatic GCTs are successfully treated with cisplatin-based chemotherapy (1). However, up to 30% of patients [...]

The advent of Online Social Networks (OSNs) and the Internet-of-Things (IoT) has catalyzed an unprecedented surge in data generation at smart device endpoints. This phenomenon necessitates robust strategies for efficient data distribution and processing on data servers. Furthermore, the burgeoning volume of data intensifies challenges associated with data placement, replication, and migration in edge-cloud computing paradigms. Considerations such as access delay, cost implications, workload balance, and data security become critical parameters in the storage and processing of data from OSNs and IoT devices. Researchers have proposed various strategies to optimize data placement costs, access latency, migration costs, and load balancing constraints. This paper presents an extensive survey on the existing strategies for data placement, data replication, and data migration. The future research directions in edge-cloud computing informed by this survey are also delineated herein. [ABSTRACT FROM AUTHOR]

PD-1 blockade (nivolumab) efficacy remains modest for metastatic sarcoma. In this paper, we present an open-label, non-randomized, non-comparative pilot study of bempegaldesleukin, a CD122-preferential interleukin-2 pathway agonist, with nivolumab in refractory sarcoma at Memorial Sloan Kettering/MD Anderson Cancer Centers (NCT03282344). We report on the primary outcome of objective response rate (ORR) and secondary endpoints of toxicity, clinical benefit, progression-free survival, overall survival, and durations of response/treatment. In 84 patients in 9 histotype cohorts, all patients experienced ≥1 adverse event and treatment-related adverse event; 1 death was possibly treatment-related. ORR was highest in angiosarcoma (3/8) and undifferentiated pleomorphic sarcoma (2/10), meeting predefined endpoints. Results of our exploratory investigation of predictive biomarkers show: CD8 + T cell infiltrates and PD-1 expression correlate with improved ORR; upregulation of immune-related pathways correlate with improved efficacy; Hedgehog pathway expression correlate with resistance. Exploration of this combination in selected sarcomas, and of Hedgehog signaling as a predictive biomarker, warrants further study in larger cohorts. The activity of PD-1 blockade in patients with sarcoma has been modest so far. Here, the authors report the results of a pilot clinical trial to assess the efficacy and safety of bempegaldesleukin, a CD122-preferential interleukin-2 (IL-2) pathway agonist, in combination with the PD1 blockade (nivolumab) in patients with locally advanced or metastatic high-grade sarcoma.

Understanding naturally acquired immune responses to Plasmodium in India is key to improving malaria surveillance and diagnostic tools. Here we describe serological profiling of immune responses at three sites in India by probing protein microarrays consisting of 515 Plasmodium vivax and 500 Plasmodium falciparum proteins with 353 plasma samples. A total of 236 malaria-positive (symptomatic and asymptomatic) plasma samples and 117 malaria-negative samples were collected at three field sites in Raurkela, Nadiad, and Chennai. Indian samples showed significant seroreactivity to 265 P. vivax and 373 P. falciparum antigens, but overall seroreactivity to P. vivax antigens was lower compared to P. falciparum antigens. We identified the most immunogenic antigens of both Plasmodium species that were recognized at all three sites in India, as well as P. falciparum antigens that were associated with asymptomatic malaria. This is the first genome-scale analysis of serological responses to the two major species of malaria parasite in India. The range of immune responses characterized in different endemic settings argues for targeted surveillance approaches tailored to the diverse epidemiology of malaria across the world.

- Abstract
Precision oncology relies on the accurate molecular characterization of individual patients with cancer at the time of treatment initiation. However, tumor molecular profiles are not static, and cancers continually evolve because of ongoing mutagenesis and clonal selection. Here, we performed genomic analyses of primary tumors, metastases, and plasma collected from individual patients to define the concordance of actionable genomic alterations and to identify drivers of metastatic disease progression. We observed a high degree of discordance of actionable genomic alterations, with 23% discordant between primary and metastatic disease sites. Among chromatin-modifying genes, ARID1A mutations, when discordant, were exclusive to the metastatic tumor samples. Our findings indicate that the high degree of lesion-to-lesion genomic heterogeneity may be a barrier to precision oncology approaches for bladder cancer and that circulating tumor DNA profiling may be preferred to tumor sequencing for a subset of patients. [Display omitted] • Mutations of chromatin-modifying genes vary between grade/stage in bladder cancer • Characterized by early branched evolution and lesion-to-lesion genomic heterogeneity • Primary and metastatic sites have 23% discordance in actionable genomic alterations • Plasma cfDNA identifies targetable genes not detected in tumor specimens Clinton et al. define the concordance of genomic alterations in urothelial carcinoma from a localized to metastatic state to identify drivers of progression. Within individual patients, there is significant discordance between primary and metastatic sites. Additionally, plasma cell-free DNA (cfDNA) can identify alterations not detected by tumor sequencing. [ABSTRACT FROM AUTHOR]

Abstract: A complex of three phosphoproteins (P0, P1 and P2) constitutes the stalk region at the GTPase center of the eukaryotic large ribosomal subunit, amongst which the protein P0 plays the most crucial role. Earlier studies have shown the functional complementation of the conditional P0-null mutant of Saccharomyces cerevisiae (W303dGP0) with orthologous P0 genes from fungal and mammalian organisms, but not the protozoan parasite Leishmania infantum. In this paper we show that the PfP0 gene from the protozoan malaria parasite Plasmodium falciparum can functionally complement the conditional P0-null W303dGP0 mutant of S. cerevisiae. Unlike the above orthologous genes, PfP0 gene could also rescue the D67dGP0 strain, which in addition to being a conditional null for ScP0 gene, is a null-mutant for both ScP1α and β genes. However, under stress conditions such as high temperature, salt and osmolarity, PfP0 gene could not rescue D67dGP0 strain. Ribosomes purified from W303dGP0 carrying PfP0 gene did not contain ScP1 protein, indicating a lack of binding of ScP1 to PfP0 protein. Yeast 2-hybrid analysis further confirmed the lack of binding of ScP1 to PfP0 protein. The polymerizing activities of ribosomes with ScP0 or PfP0 protein, in the absence of ScP1 protein, were found to be about 40–45% that of ribosomes with all the yeast P-proteins. In its sensitivity to the inhibitor sordarin, PfP0 was similar to the P0 protein from the fungus Aspergillus fumigatus. These results indicate a closer functional relationship of P. falciparum P0 gene to fungal P0 genes. [Copyright &y& Elsevier]

- Abstract
Background: Tracking the emergence and spread of antimalarial drug resistance has become critical to sustaining progress towards the control and eventual elimination of malaria in South Asia, especially India., Methods: An amplicon sequencing protocol was used for high-throughput molecular surveillance of antimalarial drug resistance in a total of 158 isolates at three sites in India: Chennai, Nadiad and Rourkela. Five genes of the Plasmodium falciparum implicated in antimalarial resistance were investigated here; Pfcrt for chloroquine resistance, Pfdhfr for pyrimethamine resistance, Pfdhps for sulfadoxine resistance, Pfk13 for artemisinin resistance and Pfmdr1 for resistance to multiple antimalarials., Results: Mutations in the propeller domain of PfK13 were observed in two samples only, however these mutations are not validated for artemisinin resistance. A high proportion of parasites from the P. falciparum dominant site Rourkela showed wild-type Pfcrt and Pfdhfr haplotypes, while mutant Pfcrt and Pfdhfr haplotypes were fixed at the P. vivax dominant sites Chennai and Nadiad. The wild-type PfDHPS haplotype was predominant across all study sites. Finally, we observed the largest proportion of suspected multi-clonal infections at Rourkela, which has the highest transmission of P. falciparum among our study sites., Conclusion: This is the first simultaneous high-throughput next generation sequencing of five complete P. falciparum genes from infected patients in India., Competing Interests: Competing interests All authors have declared that no competing interests exist.

- Abstract
A major challenge to global malaria control and elimination is early detection and containment of emerging drug resistance. Next-generation sequencing (NGS) methods provide the resolution, scalability, and sensitivity required for high-throughput surveillance of molecular markers of drug resistance. We have developed an amplicon sequencing method on the Ion Torrent PGM platform for targeted resequencing of a panel of six Plasmodium falciparum genes implicated in resistance to first-line antimalarial therapy, including artemisinin combination therapy, chloroquine, and sulfadoxine-pyrimethamine. The protocol was optimized using 12 geographically diverse P. falciparum reference strains and successfully applied to multiplexed sequencing of 16 clinical isolates from India. The sequencing results from the reference strains showed 100% concordance with previously reported drug resistance-associated mutations. Single-nucleotide polymorphisms (SNPs) in clinical isolates revealed a number of known resistance-associated mutations and other nonsynonymous mutations that have not been implicated in drug resistance. SNP positions containing multiple allelic variants were used to identify three clinical samples containing mixed genotypes indicative of multiclonal infections. The amplicon sequencing protocol has been designed for the benchtop Ion Torrent PGM platform and can be operated with minimal bioinformatics infrastructure, making it ideal for use in countries that are endemic for the disease to facilitate routine large-scale surveillance of the emergence of drug resistance and to ensure continued success of the malaria treatment policy., (Copyright © 2016 Rao et al.)
