Gain-of-function mutations in fibroblast growth factor receptor (FGFR) genes lead to chondrodysplasia and craniosynostoses. FGFR signaling has a key role in the formation and repair of the craniofacial skeleton. Here, we analyzed the impact of Fgfr2- and Fgfr3-activating mutations on mandibular bone formation and endochondral bone repair after non-stabilized mandibular fractures in mouse models of Crouzon syndrome (Crz) and hypochondroplasia (Hch).

The implementation of large-scale universal quantum computation represents a challenging and ambitious task on the road to quantum processing of information. In recent years, an intermediate approach has been pursued to demonstrate quantum computational advantage via non-universal computational models. A relevant example for photonic platforms has been provided by the Boson Sampling paradigm and its variants, which are known to be computationally hard while requiring at the same time only the manipulation of the generated photonic resources via linear optics and detection.

The only current strategy to test efficacy of novel interventions for sustained HIV control without antiretroviral therapy (ART) among people with HIV (PWH) is through an analytical treatment interruption (ATI). Inclusion of 'placebo' controls in ATIs poses ethical, logistical, and economic challenges. To understand viral dynamics and rates of post-treatment control (PTC) after ATI among PWH receiving either placebo or no intervention, we undertook an individual-participant data meta-analysis.

GABAergic neurons in basal forebrain (BF) nuclei project densely to all layers of the mouse main olfactory bulb (OB), the first relay in odor information processing. However, BF projection neurons are diverse and the contribution of each subtype to odor information processing is not known. In the present study, we used retrograde and anterograde tracing methods together with whole-brain light-sheet analyses, patch-clamp recordings coupled with optogenetic and chemogenetic approaches during spontaneous odor discrimination, and go/no-go odor discrimination/learning tests to characterize the synaptic targets in the OB of BF calretinin-expressing (CR+) GABAergic cells and to reveal their functional implications.

Background: Surgeons' reliance on intraoperative fluoroscopy during vertebroplasty procedures has raised concerns regarding the level of patient and surgeon radiation. Navigation systems have shown a potential to reduce the overall patient and medical staff exposure during dose exposure studies. The main objective of this study was to determine whether the Surgivisio platform (eCential Robotics, France), a unified imaging and navigation platform, lowers the patient dose during routine clinical usage as compared with published fluoroscopy and other navigation options that are published in the literature.

Background And Hypothesis: ATP6V1B1 encodes a subunit of the vacuolar H+-ATPase and pathogenic variants are associated with autosomal recessive distal renal tubular acidosis (dRTA) with deafness. Heterozygous variants predicted to affect a specific amino acid, Arg394, have been recurrently reported in dRTA but their significance has been unclear. We hypothesised that these variants are associated with a dominant disease mechanism.

Background: The Hemophilia Functional Ability Scoring Tool (Hemo-FAST), consisting of a patient-reported outcome (PRO) part and a clinician-reported outcome (ClinRO) part, was developed as a rapid and effective tool to assess functional mobility in clinical practice. This study (NCT04731701) aimed to validate the psychometric properties of Hemo-FAST for assessment of joint health in people with haemophilia (PwH).
Methods: PwH A or B aged ≥18 years completed questionnaires including the PRO part of Hemo-FAST and the short-form 36 health survey (SF-36) during one study visit.
While research on auditory attention in complex acoustical environment is a thriving field, experimental studies thus far have typically treated participants as passive listeners. The present study-which combined real-time covert loudness manipulations and online probe detection-investigates for the first time to our knowledge, the effects of acoustic salience on auditory attention during live interactions, using musical improvisation as an experimental paradigm. We found that musicians were more likely to pay attention to a given co-performer when this performer was made sounding louder or softer; that such salient effect was not owing to the local variations introduced by our manipulations but rather likely to be driven by the more long-term context; and that improvisers tended to be more strongly and more stably coupled when a musician was made more salient.

Many swimmers, especially small- to medium-sized animals, use intermittent locomotion that differs from continuous swimming of large species. This type of locomotion, called burst and coast, is often associated with an energetic advantage. In this work, we investigate the intermittent locomotion inspired by fish locomotion but applied to a propeller.

Pharmaceutical excipients, commonly known as inactive ingredients, encompass any substance aside from the active ingredient that fulfills a distinct and vital role in a formulation. Their purpose is to enhance specific characteristics, whether associated with the performance of the formulation or aspects related to patient comfort, safety, and acceptability. Because of the limited toxicity studies provided, and the several allergic and toxic side effects that have been reported throughout the years, it is not trivial for the regulatory agencies to approve inactive ingredients for human use.

Internal contamination by inhalation of plutonium poorly soluble compounds leads to their long time retention in alveolar macrophages inducing delayed pathology development. As previous studies highlighted co-localization of retained Pu and inflammatory lesions, this study was designed to assess the combined effect of the reference treatment (DTPA) and anti-inflammatory drugs on Pu-induced early response of macrophages in vitro. Pu colloids, mimicking poorly soluble Pu, were characterized using filtration and solid-state nuclear track detectors CR39.

Detecting surface contamination on thin thermoformed polymer plates is a critical issue for various industrial applications. Lamb waves offer a promising solution, though their effectiveness is challenged by the strong attenuation and anisotropy of the polymer plates. This issue is addressed in the context of a calcium carbonate (CaCO) layer deposited on a polypropylene (PP) plate.

Orange carotenoid protein (OCP) is a photoactive protein that mediates photoprotection in cyanobacteria. OCP binds different ketocarotenoid chromophores such as echinenone (ECN), 3'- hydroxyechinenone (hECN), and canthaxanthin (CAN). In the dark, OCP is in an inactive orange form known as OCP; upon illumination, a red active state is formed, referred to as OCP, that can interact with the phycobilisome.

A single exposure to a stressful event can result in enduring changes in behaviour. Long-term modifications in neuronal networks induced by stress are well explored but the initial steps leading to these alterations remain incompletely understood. In this study, we found that acute stress exposure triggers an immediate increase in the firing activity of calretinin-positive neurons in the paraventricular thalamic nucleus (PVT/CR+) that persists for several days in mice.

Human papillomavirus (HPV) infections drive one in 20 new cancer cases, exerting a particularly high burden on women. Most anogenital HPV infections are cleared in less than two years, but the underlying mechanisms that favour persistence in around 10% of women remain largely unknown. Notwithstanding, it is precisely this information that is crucial for improving treatment, screening, and vaccination strategies.

The development of novel therapeutic strategies enabling the selective destruction of tumors while sparing healthy tissues is of great interest to improve the efficacy of cancer chemotherapy. In this context, we designed a β-glucuronidase-responsive albumin-binding prodrug programmed to release a potent Isocombretastatin A-4 analog within the tumor microenvironment. When injected at a non-toxic dose in mice bearing orthotopic triple-negative mammary tumors, this prodrug produced a significant anticancer activity, therefore offering a valuable alternative to the systemic administration of the parent drug.
