    In this paper, we propose a novel framework for replacing advertisement contents in soccer videos with an automatic way by using deep learning strategies. We begin by applying UNET (an image segmentation convolutional neural network technique) for content segmentation and detection. Subsequently, after reconstructing the segmented content in the video frames (considering the apparent loss in detection), we will replace the unwanted content by new one using a homography mapping procedure. Furthermore, the replacement key points in each frame will be tracked into the next frames considering the camera zoom-in and zoom-out controlling. Since the movement of objects in video can disrupt the alignment between frames and correspondingly make the homography matrix calculation erroneous, we use Mask R-CNN to mask and remove the moving objects from the scene. Such framework is denominated as REP-Model which stands for a replacing model.

    Summary Eukaryotic mRNA degradation often initiates with the recruitment of the CCR4-NOT deadenylase complex and decay factors to the mRNA 3′ terminus. How the 3′-proximal decay machinery interacts with the 5′-terminal cap structure in order to engender mRNA decapping and 5′–3′ degradation is unclear. Human 4E-T is an eIF4E-binding protein that has been reported to promote mRNA decay, albeit via an unknown mechanism. Here, we show that 4E-T is a component of the mRNA decay machinery and interacts with factors including DDX6, LSM14, and the LSM1-7-PAT1 complex. We also provide evidence that 4E-T associates with, and enhances the decay of, mRNAs targeted by the CCR4-NOT deadenylase complex, including microRNA targets. Importantly, we demonstrate that 4E-T must interact with eIF4E to engender mRNA decay. Taken together, our data support a model where 4E-T promotes mRNA turnover by physically linking the 3′-terminal mRNA decay machinery to the 5′ cap via its interaction with eIF4E.

    AbstractMemristorsrepresent the fourth electrical circuit element complementing resistors, capacitors and inductors. Hallmarks of memristive behavior include pinched and frequency-dependent I–V hysteresis loops and most importantly a functional dependence of the magnetic flux passing through an ideal memristor on its electrical charge. Microtubules (MTs), cylindrical protein polymers composed of tubulin dimers are key components of the cytoskeleton. They have been shown to increase solution’s ionic conductance and re-orient in the presence of electric fields. It has been hypothesized that MTs also possess intrinsic capacitive and inductive properties, leading to transistor-like behavior. Here, we show a theoretical basis and experimental support for the assertion that MTs under specific circumstances behave consistently with the definition of a memristor. Their biophysical properties lead to pinched hysteretic current–voltage dependence as well a classic dependence of magnetic flux on electric charge. Based on the information about the structure of MTs we provide an estimate of their memristance. We discuss its significance for biology, especially neuroscience, and potential for nanotechnology applications.

    AbstractHuman skin is constantly exposed to solar light containing visible and ultraviolet radiation (UVR), a powerful skin carcinogen. UVR elicits cellular responses in epidermal cells via several mechanisms: direct absorption of short‐wavelength UVR photons by DNA, oxidative damage caused by long‐wavelength UVR, and, as we recently demonstrated, via a retinal‐dependent G protein‐coupled signaling pathway. Because the human epidermis is exposed to a wide range of light wavelengths, we investigated whether opsins, light‐activated receptors that mediate photoreception in the eye, are expressed in epidermal skin to potentially serve as photosensors. Here we show that four opsins—OPN1‐SW, OPN2, OPN3 and OPN5—are expressed in the two major human epidermal cell types, melanocytes and keratinocytes, and the mRNA expression profile of these opsins does not change in response to physiological UVR doses. We detected two OPN3 splice variants present in similar amounts in both cell types and three OPN5 splice isoforms, two of which encode truncated proteins. Notably, OPN2 and OPN3 mRNA were significantly more abundant than other opsins and encoded full‐length proteins. Our results demonstrate that opsins are expressed in epidermal skin cells and suggest that they might initiate light–induced signaling pathways, possibly contributing to UVR phototransduction.

    MicroRNA156 (miR156) is a regulator of flowering time and biomass production through regulation of members of SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) gene family. To expand our investigations on the utility of miR156 in alfalfa, we generated transgenic alfalfa expressing a heterologous miR156 from Lotus japonicus (LjmiR156a). 5′ RACE and qRT-PCR analysis confirmed that the same three SPL genes (MsSPL6, MsSPL12, and MsSPL13) targeted by MsmiR156d are also targets of LjmiR156a in alfalfa. Ectopic expression of LjmiR156a down-regulated these SPL genes in transgenic alfalfa, coupled with reduced internode length, a more extreme delay in flowering time than occurred with MsmiR156d, enhanced shoot branching, and elevated biomass production. While root length was maintained, nodulation was reduced in some transgenic genotypes. Furthermore, heterologous expression of LjmiR156a enhanced the contents of starch, soluble sugars, and phenolics in all transgenic genotypes in contrast to the impact from MsmiR156d enhancement, even though the effects on lignin, cellulose, pectin, structural sugars, flavonoids, and carotenoids were variable among the new alfalfa genotypes. The variations among the traits/genotypes reflect the change in expression of alfalfa SPL genes targeted by LjmiR156a and show that LjmiR156a could be employed as a tool to improve quality and yield of alfalfa biomass.

    Abstract Heat shock protein 90 (HSP90) modulates exercise‐induced cutaneous vasodilation in young men via nitric oxide synthase (NOS), but only when core temperature is elevated ~1.0°C. While less is known about modulation of this heat loss response in women during exercise, sex differences may exist. Further, the mechanisms regulating cutaneous vasodilation can differ between exercise‐ and passive‐heat stress. Therefore, in 11 young women (23 ± 3 years), we evaluated whether HSP90 contributes to NOS‐dependent cutaneous vasodilation during exercise (Protocol 1) and passive heating (Protocol 2) and directly compared responses between end‐exercise and a matched core temperature elevation during passive heating. Cutaneous vascular conductance (CVC%max) was measured at four forearm skin sites continuously treated with (a) lactated Ringers solution (control), (b) 178 μM Geldanamycin (HSP90 inhibitor), (c) 10 mM L‐NAME (NOS inhibitor), or (d) combined 178 μM Geldanamycin and 10 mM L‐NAME. Participants completed both protocols during the early follicular (low hormone) phase of the menstrual cycle (0–7 days). Protocol 1: participants rested in the heat (35°C) for 70 min and then performed 50 min of moderate‐intensity cycling (~55% VO2peak) followed by 30 min of recovery. Protocol 2: participants were passively heated to increase rectal temperature by 1.0°C, comparable to end‐exercise. HSP90 inhibition attenuated CVC%max relative to control at end‐exercise (p < .05), but not during passive heating. While NOS inhibition and combined HSP90 + NOS inhibition attenuated CVC%max relative to control for both protocols (all p < .05), they did not differ from each other. We show that HSP90 modulates cutaneous vasodilation NOS‐dependently during exercise in young women, with no effect during passive heating, despite a similar NOS contribution. We evaluated whether HSP90 contributes to NOS‐dependent cutaneous vasodilation during exercise and passive heating in young women. We directly compared these responses at end‐exercise and the matched core temperature elevation during passive heating. We showed that HSP90 modulates cutaneous vasodilation NOS‐dependently during exercise in young women, while there was no effect of HSP90 inhibition during passive heating, despite a similar NOS contribution.

    C. It appeared that strains from Europe were more prone to lose their TTSS locus compared to Canadian strains. More specifically, it was not possible to induce TTSS loss in Canadian strains that have AsaGEI2a, a genomic island, and prophage 3, or in Canadian strains without a genomic island. A comparative genomic approach revealed an almost perfect correlation between the presence of a cluster of genes, not yet characterized, and the susceptibility of various groups of strains to lose their locus. This cluster of genes encodes putative proteins with DNA binding capacity and phage proteins. This discovery creates new opportunities in the study of pAsa5 thermosensitivity. C. The loss of the locus is due to the recombination of the insertion sequences flanking the TTSS region. However, the mechanism involved in this recombination is still elusive. Here, we analyzed 22 A. salmonicida subsp. salmonicida strains that had already lost their TTSS locus, and we systematically explored another 47 strains for their susceptibility to lose the same locus when grown at 25 ° The type three secretion system (TTSS) locus of Aeromonas salmonicida subsp. salmonicida, located on the plasmid pAsa5, is known to be lost when the bacterium is grown at temperatures of 25 °

    AbstractBackgroundNot all healthcare professionals are familiar with nutrigenomics. However, they recognise that nutrigenomics has great potential for the development of preventive health approaches. The present study aimed to provide an overall picture of the current situation about nutrigenomics in the practice of registered dietitians (RDs) from the province of Quebec (Canada).MethodsThree hundred and seventy‐three RDs members of the Ordre professionnel des diététistes du Québec completed an online survey that included 34 questions, most of which were closed‐ended questions.ResultsOverall, 76.9% of RDs knew about nutrigenomics. Among RDs with <5 years of experience, 49.2% knew about genetic testing related to nutrition compared to 11.7% for RDs with over 25 years of experience. Currently, 75.9% of RDs working in clinical nutrition in the public sector consider that they do not have the basic knowledge to integrate nutrigenomics in their practice compared to 62.9% for RDs in private practice. When asked about main limitations of genetic testing related to nutrition, RDs considered that genetic testing does not consider the other determinants of health, that genetic testing and their results have poor accuracy, and that there is a lack of scientific evidence. Concerns remained about ethical and legal aspects and its difficult application as a result of poor understanding and/or interpretation by professionals and/or customers. The high costs of these tests were also noted as a limitation.ConclusionsRegistered dietitians know and are interested in nutrigenomics, especially those with less experience, although they do not feel adequately qualified to integrate findings from nutrigenomics into their practice.

    Populations of Redside Dace Clinostomus elongatus have declined in many areas across the species' North American range. Therefore, the development of sperm cryopreservation technology would provide an invaluable means of preserving genetic diversity in populations that are in imminent danger of extirpation. We developed cryopreservation protocols by testing the effects of diluent (buffered sperm motility-inhibiting saline solution [BSMIS]; BSMIS+ glycine; sucrose; and Hanks' balanced salt solution [HBSS]), cryoprotectant (dimethyl sulfoxide [DMSO]; propylene glycol [PG]; N,N-dimethylacetamide [DMA]; and methanol), freezing rate (1, 5, and 10 degrees C/min), and male-to-male variation on sperm quality. Incubating sperm in extenders affected motility; BSMIS+ glycine + methanol, BSMIS+ glycine + PG, and HBSS + methanol were the only treatments for which motility was not significantly different from that of fresh sperm. Sperm frozen with sucrose had higher motility than sperm frozen with BSMIS + glycine, and sperm frozen with DMSO had higher motility than sperm frozen with methanol. Freezing rates were evaluated for BSMIS + glycine, HBSS, and sucrose; all diluents were frozen with DMSO. The effect of freezing rate was not significant for BSMIS + glycine or for HBSS, but an effect was detected for sucrose, with sperm frozen at 5 degrees C/min or 10 degrees C/min having higher motility than sperm frozen at 1 degrees C/min. The effect of extender was not significant at 1 degrees C/min or 5 degrees C/min, but an effect was detected at 10 degrees C/min such that sperm frozen with sucrose had the highest motility. Male-to-male variability was evaluated by using sucrose + DMSO and a freezing rate of 10 degrees C/min. For these males, the sperm motility recovery index ranged from 6.67% to 79.27%, and the sperm velocity recovery index ranged from 21.37% to 57.33%. Our findings demonstrate that cryopreservation of Redside Dace sperm in a sucrose + DMSO extender at a freezing rate of 10 degrees C/min is adequate for preserving genetic diversity via sperm banks.

    The success of hematopoietic stem cell transplantation depends in part on the number and the quality of cells transplanted. Cryoinjuries during freezing and thawing reduce the ability of hematopoietic stem and progenitor cells (HSPCs) to proliferate and differentiate after thawing. Up to 20% of the patients undergoing umbilical cord blood (UCB) transplant experience delayed or failed engraftment, likely because of the inadequate hematopoietic potency of the unit. Therefore, the optimization of cryopreservation protocols, with an emphasis on the preservation of HSPCs, is an important issue. Current protocols typically utilize a 10% dimethyl sulfoxide cryoprotectant solution. This solution ensures 70–80% post-thaw cell viability by diluting intracellular solutes and maintaining the cell volume during cryopreservation. However, this solution fails to fully protect HSPCs, resulting in the loss of potency. Therefore, a new class of cryoprotectants (N-aryl-d-aldonamides) was designed and assessed for the ability to inhibit ice recrystallization and to protect HSPCs against cryoinjury. Several highly active ice recrystallization inhibitors were discovered. When used as additives to the conventional cryoprotectant solution, these nontoxic small molecules improved the preservation of functionally divergent hematopoietic progenitors in the colony-forming unit and long-term culture-initiating cell assays. By contrast, structurally similar compounds that did not inhibit ice recrystallization failed to improve the post-thaw recovery of myeloid progenitors. Together, these results demonstrate that the supplementation of cryopreservation solution with compounds capable of controlling ice recrystallization increases the post-thaw function and potency of HSPCs in UCB. This increase may translate into reduced risk of engraftment failure and allow for greater use of cryopreserved cord blood units.

    In this paper, we propose a novel framework for replacing advertisement contents in soccer videos with an automatic way by using deep learning strategies. We begin by applying UNET (an image segmentation convolutional neural network technique) for content segmentation and detection. Subsequently, after reconstructing the segmented content in the video frames (considering the apparent loss in detection), we will replace the unwanted content by new one using a homography mapping procedure. Furthermore, the replacement key points in each frame will be tracked into the next frames considering the camera zoom-in and zoom-out controlling. Since the movement of objects in video can disrupt the alignment between frames and correspondingly make the homography matrix calculation erroneous, we use Mask R-CNN to mask and remove the moving objects from the scene. Such framework is denominated as REP-Model which stands for a replacing model.

    Summary Eukaryotic mRNA degradation often initiates with the recruitment of the CCR4-NOT deadenylase complex and decay factors to the mRNA 3′ terminus. How the 3′-proximal decay machinery interacts with the 5′-terminal cap structure in order to engender mRNA decapping and 5′–3′ degradation is unclear. Human 4E-T is an eIF4E-binding protein that has been reported to promote mRNA decay, albeit via an unknown mechanism. Here, we show that 4E-T is a component of the mRNA decay machinery and interacts with factors including DDX6, LSM14, and the LSM1-7-PAT1 complex. We also provide evidence that 4E-T associates with, and enhances the decay of, mRNAs targeted by the CCR4-NOT deadenylase complex, including microRNA targets. Importantly, we demonstrate that 4E-T must interact with eIF4E to engender mRNA decay. Taken together, our data support a model where 4E-T promotes mRNA turnover by physically linking the 3′-terminal mRNA decay machinery to the 5′ cap via its interaction with eIF4E.

    AbstractMemristorsrepresent the fourth electrical circuit element complementing resistors, capacitors and inductors. Hallmarks of memristive behavior include pinched and frequency-dependent I–V hysteresis loops and most importantly a functional dependence of the magnetic flux passing through an ideal memristor on its electrical charge. Microtubules (MTs), cylindrical protein polymers composed of tubulin dimers are key components of the cytoskeleton. They have been shown to increase solution’s ionic conductance and re-orient in the presence of electric fields. It has been hypothesized that MTs also possess intrinsic capacitive and inductive properties, leading to transistor-like behavior. Here, we show a theoretical basis and experimental support for the assertion that MTs under specific circumstances behave consistently with the definition of a memristor. Their biophysical properties lead to pinched hysteretic current–voltage dependence as well a classic dependence of magnetic flux on electric charge. Based on the information about the structure of MTs we provide an estimate of their memristance. We discuss its significance for biology, especially neuroscience, and potential for nanotechnology applications.
