Collisions with buildings cause up to 1 billion bird fatalities annually in North America. Bird-building collisions have recently received increased conservation, research, and policy attention. However, efforts to reduce collisions would benefit from studies conducted at large spatial scales across multiple study sites, with standardized methods, and with consideration of species- and life history-related variation and correlates of collisions. We addressed these research needs with a coordinated data collection effort at 40 sites across North America. We estimated collision vulnerability for 40 bird species by accounting for their North American population abundance, distribution overlap with study sites, and sampling effort. Of 10 species we identified as most vulnerable to collisions, some have been identified in past studies (e.g., Black-throated Blue Warbler [Setophaga caerulescens]) while others emerged for the first time (e.g., White-breasted Nuthatch [Sitta carolinensis]), possibly because we used a and risk correlates vary by species.

Herein, ultrasound is employed as a microscopic pressure resource to generate reactive oxygen species (ROS) for piezocatalytic tumor therapy under catalytic mediation by piezoelectric tetragonal BaTiO3 (T-BTO). Under the ultrasonic vibration, the electrons and holes are unpaired and they are separated by the piezoelectricity, resulting in the establishment of a strong built-in electric field, which subsequently catalyzes the generation of ROS such as toxic hydroxyl (• OH) and superoxide radicals (• O2 - ) in situ for tumor eradication. This modality shows intriguing advantages over typical sonoluminescence-activated sonodynamic therapy, such as more stable sensitizers and dynamical control of redox reaction outcomes. Furthermore, according to the finite element modeling simulation, the built-in electric field is capable of modulating the band alignment to make the toxic ROS generation energetically favorable. Both detailed in vitro cellular level evaluation and in vivo tumor xenograft assessment have demonstrated that an injectable T-BTO-nanoparticles-embedded thermosensitive hydrogel will substantially induce ultrasound irradiation-triggered cytotoxicity and piezocatalytic tumor eradication, accompanied by high therapeutic biosafety in vivo.Tooth root development occurs through the interaction of multiple growth factors and transcription factors expressed in Hertwig's epithelial root sheath (HERS) and dental mesenchyme. Previously, we demonstrated that bobby sox homolog (Bbx) regulates odontoblast differentiation of human dental pulp stem cells. Here, we generated Bbx knockout (Bbx-/- ) mice to address the functional role of Bbx in tooth formation. During tooth development, Bbx was expressed in both dental epithelium and mesenchyme. However, molar and incisor morphology in Bbx-/- mice at postnatal Day 0 (P0) exhibited no prominent abnormalities compared with their wild-type (Bbx+/+ ) littermates. Until P28, the crown morphology in Bbx-/- mice was not distinctively different from Bbx+/+ littermates. learn more Meanwhile, the length of the mandibular base in Bbx-/- mice was notably less at P28. Compared with Bbx+/+ mice, the mesial and distal root lengths of the first molar were reduced by 21.33% and 16.28% at P14 and 16.28% and 16.24% at P28, respectively, in Bbx-/- mice. The second molar of Bbx-/- mice also showed 10.16% and 6.4% reductions at P28 in the mesial and distal lengths, compared with Bbx+/+ mice, respectively. The gene expression analysis during early tooth root formation (P13) showed that the expression of dentin sialophosphoprotein (Dspp) was significantly decreased in Bbx-/- mice. Collectively, our data suggest that Bbx participates in tooth root formation and might be associated with the regulation of Dspp expression.Over the last decade, the development of new treatments for haemophilia has progressed at a very rapid pace. Despite all the promising advances in protein products, the prospect offered by gene therapy of a single potentially lifelong treatment remains attractive for people with haemophilia. Transfer to the liver of coagulation factor VIII (FVIII) or factor IX (FIX) transgenes has indeed the potential to stably restore the dysfunctional coagulation process. Recombinant adeno-associated virus (AAV)-derived vectors are widely employed for liver-directed gene therapy, given their very good efficacy and safety profile, shown in several preclinical and clinical studies. However, there are some limitations associated with AAV vectors, such as their predominantly episomal nature in the nucleus of target cells and the widespread pre-existing immunity against the parental virus in humans. By contrast, HIV-derived lentiviral vectors (LV) integrate into the target cell chromatin and are maintained as the cells duplicate their genome, a potential advantage for establishing long-term expression especially in paediatric patients, in which the liver undergoes substantial growth. Systemic administration of LV allowed stable multi-year transgene expression in the liver of mice and dogs. More recently, improved phagocytosis-shielded LV were generated, which, following intravenous administration to non-human primates, showed selective targeting of liver and spleen and enhanced hepatocyte gene transfer, achieving up to supra-normal activity of both human FVIII and FIX transgenes. These studies support further preclinical assessment and clinical evaluation of in vivo liver-directed LV gene therapy for haemophilia.Key points Increased plasma nitrite concentrations may have beneficial effects on skeletal muscle function. The physiological basis explaining these observations has not been clearly defined and it may involve positive effects on muscle contraction force, microvascular O2 delivery and skeletal muscle oxidative metabolism. In the isolated canine gastrocnemius model, we evaluated the effects of acute nitrite infusion on muscle force and skeletal muscle oxidative metabolism. Under hypoxic conditions, but in the presence of normal convective O2 delivery, an elevated plasma nitrite concentration affects neither muscle force, nor muscle contractile economy. In accordance with previous results suggesting limited or no effects of nitrate/nitrite administrations in highly oxidative and highly perfused muscle, our data suggest that neither mitochondrial respiration, nor muscle force generation are affected by acute increased concentrations of NO precursors in hypoxia. Abstract Contrasting findings have been reported concerning the effects of augmented nitric oxide (NO) on skeletal muscle force production and oxygen consumption ( V ̇ O 2 ).
