We report the identification of a new family of proteins, termed the HEM family, which show distinct expression patterns in blood cells and the central nervous system. Through the isolation and characterization of the corresponding brain-specificDrosophila(dhem-2) and rat orthologues (Hem-2), and through the detection of theCaenorhabditis elegansHem-2 orthologue in the database, we show that this
Colloidal all-inorganic perovskite nanocrystals have gained significant attention as a promising material for both fundamental and applied research due to their excellent emission properties. However, reported photoluminescence quantum yields (PL QYs) of blue-emitting perovskite nanocrystals are rather low, mostly due to the fact that the h
The plant microbiome is an important factor for plant health and productivity. While the impact of nitrogen (N) availability for plant growth and development is well established, its influence on the microbial phyllosphere community structure is unknown. We hypothesize that nitrogen impacts the growth and abundance of several microorganisms on the leaf surface. The bacterial and fungal communities
Bacterial pathogens evolve during the course of infection as they adapt to the selective pressures that confront them inside the host. Identification of adaptive mutations and their contributions to pathogen fitness remains a central challenge. Although mutations can either target intergenic or coding regions in the pathogen genome, studies of host adaptation have focused predominantly on molecula
As it is well known, one of the keys to improve traffic performance of two lane rural roads with high traffic volumes is to provide passing sections. However, providing a long segment in which the passing maneuver is allowed, is not always feasible, especially when suburban areas are considered. The retrofitting of some road sections by adding a passing relief lane can improve traffic performance
Objective. Obsessive-compulsive disorder (OCD) is a heterogeneous condition with well-established symptom dimensions across the lifespan. The objective of the present study was to use network analysis to investigate the internal structure and central features of these dimensions in unselected schoolchildren and in youth with OCD.Method. We estimated the network structure of OCD symptom dimensions
Bifurcating Futures, 2014HD video, 9:46 min.Through the staging of an experienced dancer, the video work Bifurcating Futures explores the body’s limitations and potentials in relation to modernist and futuristic architecture in the Esposizione Universale di Roma (EUR) district of Rome. The dancer’s movements are ruptured by fragments from Thom Donovan’s poem “The Commons.”In the video, the dancer
The X-linked DDX3X gene encodes an ATP-dependent DEAD-box RNA helicase frequently altered in various human cancers, including melanomas. Despite its important roles in translation and splicing, how DDX3X dysfunction specifically rewires gene expression in melanoma remains completely unknown. Here, we uncover a DDX3X-driven post-transcriptional program that dictates melanoma phenotype and poor dise
The deposition of dust on snow accelerates melt by perturbing snow albedo, directly by darkening the snow surface and indirectly by enhancing snow grain growth. The snow darkening process impacts hydrology by shifting runoff timing and magnitude. Dust on snow deposition has been documented in the Wasatch Mountains, snowmelt from which accou
Optical DNA mapping (ODM) allows visualization of long-range sequence information along single DNA molecules. The data can for example be used for detecting long range structural variations, for aiding DNA sequence assembly of complex genomes and for mapping epigenetic marks and DNA damage across the genome. ODM traditionally utilizes sequence specific marks based on nicking enzymes, combined with
Although acute flaccid paralysis (AFP) surveillance is the “gold standard” for detecting cases of polio, environmental surveillance can provide supplementary information in the absence of paralytic poliomyelitis cases. This study aimed to detect the introduction and/or circulation of wild poliovirus or vaccine-derived polioviruses (VDPV) in wastewater, covering a significant population of Armenia,
The effects of N iodoacetyl 2 amino 2 deoxy (D) glucose and various N bromoacetylglycosylamines on the release of insulin from microdissected pancreatic islets of non inbred ob/ob mice were studied. N Bromoacetyl β (D) glucosylamine (10 m(M)) initiated insulin release in the absence of (D) glucose and, at concentrations of 2.5-10 m(M), but not 20 m(M), potentiated insulin release in response to 10
The Greatwall kinase/Mastl is an essential gene that indirectly inhibits the phosphatase activity toward mitotic Cdk1 substrates. Here we show that although Mastl knockout (MastlNULL) MEFs enter mitosis, they progress through mitosis without completing cytokinesis despite the presence of misaligned chromosomes, which causes chromosome segregation defects. Furthermore, we uncover the requirement of
The two mitotic centrosomes direct spindle bipolarity to maintain euploidy. Centrosome amplification - the acquisition of ≥3 centrosomes - generates multipolar mitoses, aneuploidy, and chromosome instability to promote cancer biogenesis. While much evidence suggests that Cdk2 is the major conductor of the centrosome cycle and that it mediates centrosome amplification induced by various altered tum
BACKGROUND: Patients with platinum-sensitive recurrent ovarian cancer are a heterogeneous group, and it is not possible to accurately predict the progression-free survival (PFS) in these patients. We developed and validated a nomogram to help improve prediction of PFS in patients treated with platinum-based chemotherapy.METHODS: The nomogram was developed in a training cohort (n=955) from the CALY
