These variants, predicted to truncate FVIII in the C1 domain, were detected in the patient. CHO cells transduced with the two FVIII transcripts, confirmed protein retention and absence of the C2 domain. HA mice injected with LV carrying FVIII mutants, partially recovered FVIII activity without the appearance of anti-FVIII antibodies. CONCLUSIONS Herein, we demonstrate the aberrant impact of a FVIII synonymous mutation on its transcription, activity and pathological outcomes. Our data underline the importance of increasing the knowledge regarding the functional consequences of F8 mutations and their link to inhibitor development and an effective replacement therapy.

Natural hosts are asymptomatic or show moderate signs of the disease. Accidental hosts develop a severe, often lethal, form of the disease. All young southern tamanduas died suddenly at the zoo in the city of João Pessoa, Brazil. The animals were found dead without any noticeable clinical signs. Necropsy revealed extensive haemorrhage in the subcutaneous tissues, kidneys, lungs in addition to the presence of red fluid in the thoracic, abdominal and pericardial cavities. Histopathology of kidneys exhibited acute interstitial nephritis and tubular necrosis. Immunohistochemical staining revealed typical leptospiral wavy forms and aggregates in the lumen of several kidney tubules and lungs. Pathological and molecular investigations confirmed Leptospira interrogans infection. Phlorizin manufacturer The adult tamanduas did not present with clinical alterations. To our knowledge, this investigation is the first study to report that leptospirosis should be considered as a possible cause of death in tamanduas. This article warns of the risks of anthropization with respect to Leptospira transmission to tamanduas, other animals and humans. © 2020 Blackwell Verlag GmbH.Cystinuria Type A is a relatively common genetic kidney disease occurring in 1 in 7,000 people worldwide that results from mutation of the cystine transporter rBAT encoded by Slc3a1. We used CRISPR/Cas9 technology to engineer cystinuria Type A mice via genome editing of the C57BL/6NHsd background. These mice are an improvement on currently available models as they are on a coisogenic genetic background and have a single defined mutation. In order to use albinism to track Cas9 activity, we co-injected gRNAs targeting Slc3a1 and tyrosinase (Tyr) with Cas9 expressing plasmid DNA into mouse embryos. Two different Slc3a1 mutational alleles were derived, with homozygous mice of both demonstrating elevated urinary cystine levels, cystine crystals, and bladder stones. We used whole genome sequencing to evaluate for potential off-target editing. No off-target indels were observed for the top 10 predicted off-targets for Slc3a1 or Tyr. Therefore, we used CRISPR/Cas9 to generate coisogenic albino cystinuria Type A mice that could be used for in vivo imaging, further study, or developing new treatments of cystinuria. © 2020 Wiley Periodicals, Inc.BACKGROUND Ultrasound has become the initial approach to evaluating thyroid nodules, facilitating the distinction between benign and malignant nodules based on composition, echogenicity, nodule border or margin, shape, the presence of calcifications, and nodule dimensions. The American College of Radiology (ACR) recommended the Thyroid Imaging Reporting and Data System (TI-RADS) as a classification system to standardize thyroid ultrasound reports and to predict the probability of malignancy in thyroid nodules using a scoring system (TR1-TR5) based on multiple ultrasound characteristics and nodule size. Fine-needle aspiration (FNA) is recommended as the next step for nodules that warrant further workup. The authors assessed the accuracy of the ACR TI-RADS based on the corresponding FNA cytology results (Bethesda system diagnoses I-VI). METHODS ACR TI-RADS ultrasound reports and corresponding FNA cytology diagnoses from January 1, 2018 to August 30, 2018 were evaluated. RESULTS From January 1, 2018 to August 30, 2018, 2306 thyroid ultrasound-guided FNAs were performed at our institution. Of 2306 cases, 361 had ACR TI-RADS reports available. The majority of FNAs were TR4 (180; 49.9%) or TR3 (108; 29.9%). No TR2 or TR3 nodules were associated with Bethesda category V or VI diagnoses. The majority of TR4 nodules (142 of 180; 78.9%) and TR5 nodules (42 of 65; 64.6%) exhibited benign (Bethesda category II) cytology. Fourteen TR5 cases (21.5%) had malignant (Bethesda category VI) cytology. CONCLUSIONS Although there were no TR2 or TR3 malignant (Bethesda category VI) diagnoses, and there were only a few malignancies in the TR4 and TR5 categories, the current results reassert the notion that the ACR TI-RADS scoring system shows at least some correlation between benign or malignant cytology diagnoses, as illustrated by the greater number of malignant cases in the higher ACR TI-RADS categories. © 2020 American Cancer Society.Pure 2D lead-iodide perovskites typically demonstrate poor charge transport and compromised visible light absorption, relative to their 3D congeners. This hinders their potential use as solar absorbers. Herein, we report systematic tuning of pyridinium-based templating cations to introduce intermolecular interactions that provide access to a series of new 2D lead-iodide perovskites with reduced inter-octahedral distortions (largest Pb-( μ -I)-Pb bond angles of 170 - 179°) and very short inorganic interlayer separations (shortest I···I contacts ≤ 4.278 - 4.447 Å). These features manifest in reduced band gaps (2.35 - 2.46 eV) and relaxed dielectric confinement (excitonic binding energies of 130 - 200 meV). As a consequence, they demonstrate (more than 10-fold) improved photo- and electrical conductivities relative to conventional 2D lead-iodide perovskites, such as that templated by 2-(1-naphthyl)ethylammonium). Through computational studies, the origin of this behaviour was shown to derive from a combination of short iodoplumbate layer separations and the aromaticity of the organic dications.
