Anthropogenic activities are dramatically changing marine ecosystems. Wildlife tourism is one of the fastest growing sectors of the tourism industry and has the potential to modify the natural environment and behaviour of the species it targets. Here, we used a novel method to assess the effects of wildlife tourism on the activity of white sharks ( Carcharodon carcharias ). High frequency three-axis acceleration loggers were deployed on ten white sharks for a total of ~9 days. A combination of multivariate and univariate analysis revealed that the increased number of strong accelerations and vertical movements when sharks are interacting with cage-diving operators result in an overall dynamic body acceleration (ODBA) ~61% higher compared with other times when sharks are present in the area where cage-diving occurs...

The case of Charlie Gard, an infant with a genetic illness whose parents sought experimental treatment in the USA, brought important debates about the moral status of parents and children to the public eye. After setting out the facts of the case, this article considers some of these debates through the lens of parental rights. Parental rights are most commonly based on the promotion of a child's welfare; however, in Charlie's case, promotion of Charlie's welfare cannot explain every fact of the case. Indeed, some seem most logically to extend from intrinsic parental rights, that is, parental rights that exist independent of welfare promotion...

Targeted therapies against FLT3-mutated acute myeloid leukemia have shown limited clinical efficacy primarily because of the acquisition of secondary mutations in FLT3 and persistent activation of downstream pro-survival pathways such as MEK/ERK, PI3K/AKT, and STAT5. Activation of these additional kinases may also result in phosphorylation of tumor suppressor proteins promoting their nuclear export. Thus, co-targeting nuclear export proteins (i.e., XPO1) and FLT3 concomitantly may be therapeutically effective...

The amount of marine debris washed ashore on a beach in Newport, Oregon, USA was observed automatically and sequentially using a webcam system. To investigate potential causes of the temporal variability of marine debris abundance, its time series was compared with those of satellite-derived wind speeds and sea surface height off the Oregon coast. Shoreward flow induced by downwelling-favorable southerly winds increases marine debris washed ashore on the beach in winter. We also found that local sea-level rise caused by westerly winds, especially at spring tide, moved the high-tide line toward the land, so that marine debris littered on the beach was likely to re-drift into the ocean...

Sorghum grains with different applications had different phenolic profiles, which were corresponded to various antioxidant capacities. In this study, total phenolic, proanthocyanidins and flavonoids contents, as well as contents of individual phenolic compounds from sorghum grains with various applications were determined, and their antioxidant capacities were evaluated. Total phenolic contents (TPC) and total proanthocyanidins contents (TPAC) showed strong correlation with antioxidant activities ( r > 0...

All-electronic DNA biosensors based on graphene field effect transistors (GFETs) offer the prospect of simple and cost-effective diagnostics. For GFET sensors based on complementary probe DNA, the sensitivity is limited by the binding affinity of the target oligonucleotide, in the nM-range for 20-mer targets. We report a ~20,000× improvement in sensitivity through the use of engineered hairpin probe DNA that allows for target recycling and hybridization chain reaction. This enables detection of 21-mer target DNA at sub-fM concentration and provides superior specificity against single-base mismatched oligomers...

OBJECTIVES: Asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) is recognized increasingly as a distinct clinical entity and is associated with higher comorbidities compared with patients with asthma and COPD alone. Little is known about the leading causes of death related to ACO in the US general population, however. Our aim was to define the causes of mortality among patients with ACO compared with asthma and COPD in the US population. METHODS: We examined questions using the National Health and Nutrition Examination Survey III database linked to the National Death Index...

Robust fluorescence-based biosensors are emerging as critical tools for high-throughput strain improvement in synthetic biology. Many biosensors are developed in model organisms where sophisticated synthetic biology tools are also well established. However, industrial biochemical production often employs microbes with phenotypes that are advantageous for a target process, and biosensors may fail to directly transition outside the host in which they are developed. In particular, losses in sensitivity and dynamic range of sensing often occur, limiting the application of a biosensor across hosts...

Pterosaurs were a successful group of Mesozoic flying reptiles. They were the first vertebrate group to achieve powered flight and varied enormously in morphology and ecology, occupying a variety of niches and developing specialized feeding strategies. Ecomorphological principles suggest this variation should be reflected by great morphological diversity in the lower jaw, given that the mandible served as the primary apparatus for prey acquisition. Here we present the first study of mandibular shape disparity in pterosaurs and aim to characterize major aspects of variation...

In recent years, there has been increased interest in carcinomas of the urologic tract, that demonstrate association with the polyoma virus BK arising in immunosuppressed individuals, though the nature of this association is uncertain. To begin to understand this phenomenon, we reviewed the clinical, morphological, and immunohistochemical features of 11 carcinomas of the urologic tract, mainly urothelial (N = 9) and collecting duct carcinomas (N = 2), occurring during immunosuppression, and expressing polyoma virus T-antigen by immunohistochemistry...

Circadian rhythms coordinate an organism's activities and biological processes to the optimal time in the 24-h daylight cycle. We previously demonstrated that male C57BL/6 mice develop sepsis more rapidly when the disease is induced in the nighttime versus the daytime. In this report, we elucidate the mechanism of this diurnal difference. Sepsis was induced via cecal ligation and puncture (CLP) at zeitgeber time (ZT)-19 (2 am) or ZT-7 (2 pm). Like the males used in our prior study, female C57BL/6 mice had a worse outcome when CLP was induced at ZT-19 versus ZT-7, and these effects persisted when we pooled the data from both sexes...

Murine norovirus (MNV) is an RNA virus that can prove lethal in mice with impaired innate immunity. We found that MNV-4 infection of Stat1-/- mice was not lethal, but produced a 100% penetrant, previously undescribed lymphatic phenotype characterized by chronic-active lymphangitis with hepatitis, splenitis, and chronic cecal and colonic inflammation. Lesion pathogenesis progressed from early ileal enteritis and regional dilated lymphatics to lymphangitis, granulomatous changes in the liver and spleen, and ultimately, typhlocolitis...

This paper explores patients' views and experiences of undergoing treatment-focused BRCA1 and BRCA2 genetic testing (TFGT), either offered following triaging to clinical genetics (breast cancer) or as part of a mainstreamed care pathway in oncology (ovarian cancer). Drawing on 26 in-depth interviews with patients with breast or ovarian cancer who had undergone TFGT, this retrospective study examines patients' views of genetic testing at this point in their care pathway, focusing on issues, such as initial response to the offer of testing, motivations for undergoing testing, and views on care pathways...

BACKGROUND: Clinical high risk (CHR) status is characterized by impairments in social cognition, but questions remain concerning their stability over development. In cross-sectional analysis of a large naturalistic sample, the current study examined whether those at CHR status show deviant trajectories for age-related change in social cognitive ability, and whether these trajectories are influenced by treatment history. METHOD: Emotion perception (EP) and theory of mind (ToM) were assessed in 675 CHR and 263 healthy comparison (HC) participants aged 12-35...

Exploiting the host endocytic trafficking pathway is a common mechanism by which bacterial exotoxins gain entry to exert virulent effects upon the host cells. A previous study identified a small-molecule, 1-(2,6-dimethyl-1-piperidinyl)-3-[(2-isopropyl-5-methylcyclohexyl)oxy]-2-propanol, that blocks the process of anthrax lethal toxin (LT) cytotoxicity. Here, we report the characterization of the bioactivity of this compound, which we named RC1. We found that RC1 protected host cells independently of LT concentration and also blocked intoxication by other bacterial exotoxins, suggesting that the target of the compound is a host factor...

Background Ameloblastoma is a rare benign odontogenic tumor with a metastasis rate estimated at 2% of cases, mainly involving the lung (80%) and lymph nodes (20%). Methods We hereby present the case of a 26 year old patient with a history of locally recurrent mandibular ameloblastoma who developed a temporal intracranial ameloblastoma tumor requiring a collaborative neurosurgical and maxillo-facial radical surgical approach. Conclusion Although ameloblastomas are histologically benign, the temporal topography questions the dissemination pathophysiology of the tumor (metastasis or local extension through temporal muscle fibers), mainly relevant in cases of multiple recurrences...

PURPOSE: The goal of this study was to develop a fast MR fingerprinting (MRF) method for simultaneous T1 and T2 mapping in DCE-MRI studies in mice. METHODS: The MRF sequences based on balanced SSFP and fast imaging with steady-state precession were implemented and evaluated on a 7T preclinical scanner. The readout used a zeroth-moment-compensated variable-density spiral trajectory that fully sampled the entire k-space and the inner 10 × 10 k-space with 48 and 4 interleaves, respectively...
