Circular RNAs (circRNAs) are a new group of non-coding RNAs that play vital roles in cancer occurrence, including gastric cancer (GC). Nevertheless, the role and underlying regulatory mechanisms of circHIPK3 in GC remain unclear.

The expression levels of circHIPK3, miR-876-5p, and phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1) were estimated by real-time quantitative polymerase chain reaction (RT-qPCR) assay. The proliferation, migration, and invasion of GC cells were determined by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl-2H-tetrazol-3-ium bromide (MTT) and transwell assay. Glutaminolysis of GC cells was assessed by measuring glutamine, glutamate, and α-ketoglutarate levels. The western blot was employed to examine the related-protein expression. The association between miR-876-5p and circHIPK3 or PIK3R1 was predicted and affirmed by bioinformatics database starBase v2.0 and dual-luciferase reporter assay, respectively. Eventually, the xenograft experiment was used to assess the role of circHI regulation of miR-876-5p/PIK3R1 axis by the mechanism of competing endogenous RNAs (ceRNA), indicating circHIPK3 was a GC-associated circRNA that promoted GC development.

The introduction of combined conventional cytostatics and pathway-specific inhibitors has opened new treatment options for several cancer types including hematologic neoplasia such as leukaemias. As the detailed understanding of the combination-induced molecular effects is often lacking, the identification of combination-induced molecular mechanisms bears significant value for the further development of interventional approaches.

Combined application of conventional cytostatic agents (cytarabine and dexamethasone) with the PI3K-inhibitor Idelalisib was analysed on cell-biologic parameters in two acute pro-B lymphoblastic leukaemia (B-ALL) cell lines. In particular, for comparative characterisation of the molecular signatures induced by the combined and mono application, whole transcriptome sequencing was performed. Atogepant Emphasis was placed on pathways and genes exclusively regulated by drug combinations.

Idelalisib + cytostatics combinations changed pathway activation for, e.g., "Retinoblastoma in cancer", "TGF-b signalling", "Cell cycle" and "DNA-damage response" to a greater extent than the two cytostatics alone. Analyses of the top-20 regulated genes revealed that both combinations induce characteristic gene expression changes.

A specific set of genes was exclusively deregulated by the drug combinations, matching the combination-specific anti-proliferative cell-biologic effects. The addition of Idelalisib suggests minor synergistic effects which are rather to be classified as additive.

Modelled outputs could be used to complement data from multi-environment trials. Field experiments were conducted in the rainy and dry seasons of 2015 and 2016 across four locations in maize growing regions of Northern Nigeria using 16 maize varieties planted under near-optimal conditions of moisture and soil nitrogen. The CERES-Maize model was calibrated using data from three locations and two seasons (rainy and dry) and evaluated using data from one location and two seasons all in 2015. Observed data from the four locations and two seasons in 2016 was used to create eight different environments. Two profile pits were dug in each location and were used separately in the simulations for each environment to provide replicated data for stability analysis in a combined ANOVA. The effects of the environment, genotype and GEI were highly significaen properly calibrated and evaluated, the CERES-Maize model can be used to generate data for GEI and stability studies of maize genotype in the absence of observed field data.Dengue illness is characterised by plasma leakage with or without bleeding, which may lead to dengue shock syndrome. Proteinuria and hypoalbuminaemia are common in dengue infection, and few cases of heavy proteinuria have been reported. Dengue infection features may mimic nephrotic syndrome in clinical practice. As dengue infection is endemic in India, it can be associated with other illnesses such as nephrotic syndrome. We report a child with nephrotic syndrome complicated with severe dengue infection.The term infant is remarkably resistant to bleeding despite physiologically low levels of procoagulant proteins. However, because of their unique haemostatic systems, neonates are vulnerable to haemorrhagic disorders. The prevention of early vitamin K deficiency bleeding (VKDB) of newborn by oral or parenteral administration of vitamin K has been well established. However, rarely, a newborn can present with bleeding manifestations even after routine vitamin K prophylaxis at birth. A 2-day-old healthy male baby presented with catastrophic pulmonary haemorrhage with severely deranged coagulation profile even after receiving vitamin K prophylaxis at birth. His presentation, initial laboratory findings and course in the hospital were very much in favour of haemophilia B, but follow-up factor IX level and clinical exome sequencing did not confirm it. However, protein induced in vitamin K absence-II was found to be raised just before the discharge, and we concluded this case as a rare presentation of classical VKDB.Systemic lupus erythematosus (SLE) is an autoimmune multisystem disease. Childhood-onset SLE is extremely rare and comprises only 10% to 20% of all cases. In this case report, we present a 9-year-old boy from northeastern India who presented with fever, cough, vague abdominal pain, lethargy and swelling of face and legs. Initial impression was one of sepsis with central nervous system (CNS) involvement and was treated accordingly. Detailed clinical examination with subsequent laboratory and imaging studies clinched the diagnosis of SLE. The patient showed rapid resolution of symptoms with immunoglobulins, cyclophosphamide and steroid therapy. A brief discussion on childhood neuropsychiatric lupus syndrome and SLE with CNS infections is included here.
