SNHG16 regulates invasion and migration of bladder cancer through induction of epithelial-to-mesenchymal transition
Abstract Bladder cancer (BCa) is one of the most common urinary malignancies in the world. Growing evidence suggests that epithelial-to-mesenchymal transition (EMT) is a major contributor for BCa metastasis. lncRNA small nucleolar RNA host gene 16 (SNHG16) has been reported as a tumor promoter in many cancers. This study aims to investigate the function and mechanism of SNHG16 on EMT in BCa. Quantitative RT-PCR (qRT-PCR) was used to determine the expression of SNHG16 in human BCa...

Fractional Theoretical Model for Gravity Waves and Squall Line in Complex Atmospheric Motion
The evolution of nonlinear gravity solitary waves in the atmosphere is related to the formation of severe weather. The nonlinear concentration of gravity solitary wave leads to energy accumulation, which further forms the disastrous weather phenomenon such as squall line. This paper theoretically proves that the formation of squall line in baroclinic nonstatic equilibrium atmosphere can be reduced to the fission process of algebraic gravity solitary waves described by the (2 + 1)-dimensional generalized...

Shear Resistance of Rock Joint under Nonuniform Normal Stress
Many factors influence the shear resistance of rock joints. Among them, the above overburden load is the most important factor. The uneven thickness of the overburden causes the joints to be subjected to the nonuniform distribution load. While the peak shear strength shows nonlinear relationship with normal stress, linear superposition cannot be used to calculate the overall shear resistance of joint under nonuniform normal stress distribution. In this paper, the nonlinear shear strength model, JRC-JCS...

Metabolic lesion-deficit mapping of human cognition
AbstractIn theory the most powerful technique for functional localization in cognitive neuroscience, lesion-deficit mapping is in practice distorted by unmodelled network disconnections and strong ‘parasitic’ dependencies between collaterally damaged ischaemic areas. High-dimensional multivariate modelling can overcome these defects, but only at the cost of commonly impracticable data scales. Here we develop lesion-deficit mapping with metabolic lesions—discrete areas of hypometabolism typically...

Cortical interneuron-mediated inhibition delays the onset of amyotrophic lateral sclerosis
AbstractAmyotrophic lateral sclerosis is a fatal disease resulting from motor neuron degeneration in the cortex and spinal cord. Cortical hyperexcitability is a hallmark feature of amyotrophic lateral sclerosis and is accompanied by decreased intracortical inhibition. Using electrophysiological patch-clamp recordings, we revealed parvalbumin interneurons to be hypoactive in the late pre-symptomatic SOD1*G93A mouse model of amyotrophic lateral sclerosis. We discovered that using adeno-associated virus-mediated...

Editorial
Every month, it is hoped that reading the Table of Contents of Brain elicits curiosity and anticipation about the latest developments in translational neuroscience. The reaction that probably does not occur, however, is consternation that men almost always outnumber women among senior authors, at least as far as their genders can be surmised from their first names. The reason that this pattern does not surprise the reader is simply that it has always been thus, yet another manifestation of the under-representation...

Basal forebrain volume reliably predicts the cortical spread of Alzheimer’s degeneration
AbstractAlzheimer’s disease neurodegeneration is thought to spread across anatomically and functionally connected brain regions. However, the precise sequence of spread remains ambiguous. The prevailing model used to guide in vivo human neuroimaging and non-human animal research assumes that Alzheimer’s degeneration starts in the entorhinal cortices, before spreading to the temporoparietal cortex. Challenging this model, we previously provided evidence that in vivo markers of neurodegeneration within...

Dissociation between frontal and temporal-parietal contributions to connected speech in acute stroke
AbstractHumans are uniquely able to retrieve and combine words into syntactic structure to produce connected speech. Previous identification of focal brain regions necessary for production focused primarily on associations with the content produced by speakers with chronic stroke, where function may have shifted to other regions after reorganization occurred. Here, we relate patterns of brain damage with deficits to the content and structure of spontaneous connected speech in 52 speakers during the...

In vivo CRISPRa decreases seizures and rescues cognitive deficits in a rodent model of epilepsy
AbstractEpilepsy is a major health burden, calling for new mechanistic insights and therapies. CRISPR-mediated gene editing shows promise to cure genetic pathologies, although hitherto it has mostly been applied ex vivo. Its translational potential for treating non-genetic pathologies is still unexplored. Furthermore, neurological diseases represent an important challenge for the application of CRISPR, because of the need in many cases to manipulate gene function of neurons in situ. A variant of...

Impaired automatic but intact volitional inhibition in primary tic disorders
AbstractThe defining character of tics is that they can be transiently suppressed by volitional effort of will, and at a behavioural level this has led to the concept that tics result from a failure of inhibition. However, this logic conflates the mechanism responsible for the production of tics with that used in suppressing them. Volitional inhibition of motor output could be increased to prevent the tic from reaching the threshold for expression, although this has been extensively investigated...
