High-fidelity remote entanglement of trapped atoms mediated by time-bin photons.

Photonic interconnects between quantum processing nodes are likely the only way to achieve large-scale quantum computers and networks. The bottleneck in such an architecture is the interface between well-isolated quantum memories and flying photons. We establish high-fidelity entanglement between remotely separated trapped atomic qubit memories, mediated by photonic qubits stored in the timing of their pulses.

Impact of Chronic Inflammatory Diseases on Clinical Pharmacokinetics of Antibody-Based Therapeutic Proteins.

Antibody-based therapeutic proteins (TPs) emerged as a promising therapeutic modality for chronic inflammatory diseases. During clinical development, the impact of disease on pharmacokinetics (PK) should be carefully considered to reliably extrapolate PK from healthy volunteers (HVs) in early-phase studies to patients in later-phase studies. This paper aimed to provide an overview of the impact of chronic inflammatory diseases on the PK of antibody-based TPs.

Moderate physical activity and higher frequency are inversely associated with incidence of frailty in middle-aged and older population: a 4-year longitudinal study in Europe.

Background: Global aging is leading to an increase in frailty patients, and physical activity (PA) may have an impact on frail in middle-aged and older population. This study aimed to explore the relationship between the frequency of different PA intensities and the incidence and prevalence of frailty in middle-aged and older adults based on the Survey of Health, Ageing, and Retirement in Europe (SHARE).

Method: Self-reported questionnaires were used to obtain information on demographics and PA, and frailty was assessed using the SHARE Frailty Instrument (SHARE-FI).

Dosing Cefazolin for Surgical Site Infection Prophylaxis in Adolescent Idiopathic Scoliosis Surgery: Intermittent Bolus or Continuous Infusion?-A Pilot Study.

Cefazolin may minimize the risk of surgical site infection (SSI) following posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). Cefazolin dosing recommendations vary and there is limited evidence for achieved tissue concentrations. We performed a randomized, controlled, prospective pharmacokinetic pilot study of 12 patients given cefazolin by either intermittent bolus (30 mg/kg every 3 h) or continuous infusion (30 mg/kg bolus followed by 10/mg/kg per hour) during PSF for AIS.

Human mutations in implicated in GABAergic synapse development in mice.

This study reports on biallelic homozygous and monoallelic variants in in three unrelated families presenting with epileptic encephalopathy associated with a broad neurological involvement characterized by microcephaly, intellectual disability, seizures, and global developmental delay. encodes for a transmembrane protein that is involved in controlling neurite outgrowth and inhibitory synapse development and that has an important role in brain function and neurological diseases. Using primary cultures of hippocampal neurons carrying patients' SLITRK3 variants and in combination with electrophysiology, we demonstrate that recessive variants are loss-of-function alleles.

Can non-renal clearance and/or bioavailability of drugs be assessed reliably in renal impairment studies with oral drug administration?

Objective: The causes for the variable susceptibility of renal clearance (CLr) and bioavailability (F) of drugs in renal impairment are still unknown. We investigated whether the impact of chronic kidney disease (CKD) on non-renal clearance (CLnr) or F can be appraised when drug administration is by the oral route only in dedicated renal impairment studies (DRIS), as is routinely done when developing drugs intended for oral use.

Materials And Methods: A literature search on DRIS administering drugs orally only or orally and intravenously was conducted.

Changes in cardiac-driven perivascular fluid movement around the MCA in a pharmacological model of acute hypertension detected with non-invasive MRI.

Perivascular spaces mediate a complex interaction between cerebrospinal fluid and brain tissue that may be an important pathway for solute waste clearance. Their structural or functional derangement may contribute to the development of age-related neurogenerative conditions. Here, we employed a non-invasive low value diffusion-weighted ECG-gated MRI method to capture perivascular fluid movement around the middle cerebral artery of the anaesthetised rat brain.

Image-Guided Magnetic Thermoseed Navigation and Tumor Ablation Using a Magnetic Resonance Imaging System.

Medical therapies achieve their control at expense to the patient in the form of a range of toxicities, which incur costs and diminish quality of life. Magnetic resonance navigation is an emergent technique that enables image-guided remote-control of magnetically labeled therapies and devices in the body, using a magnetic resonance imaging (MRI) system. Minimally INvasive IMage-guided Ablation (MINIMA), a novel, minimally invasive, MRI-guided ablation technique, which has the potential to avoid traditional toxicities, is presented.

Remote and Selective Control of Astrocytes by Magnetomechanical Stimulation.

Astrocytes play crucial and diverse roles in brain health and disease. The ability to selectively control astrocytes provides a valuable tool for understanding their function and has the therapeutic potential to correct dysfunction. Existing technologies such as optogenetics and chemogenetics require the introduction of foreign proteins, which adds a layer of complication and hinders their clinical translation.

Pooled Analysis of Gastric Emptying in Patients With Obesity: Implications for Oral Absorption Projection.

Purpose: Gastric emptying time is one of limiting factors that determines the pharmacokinetic properties of drugs administered by mouth. Despite the high prevalence of obesity worldwide, modifications in gastric emptying time have not been systematically addressed in this set of patients. The current analysis aims to quantitatively address obesity-related changes in gastric emptying time of solids, semisolids, and liquids compared with lean individuals, highlighting the relevant pharmacokinetic implications of oral drug absorption in patients with obesity.

Attitude is everything: keep probe pitch neutral during side-fire prostate biopsy. A simulator study.

Objectives: To develop and validate on a simulator a learnable technique to decrease deviation of biopsied cores from the template schema during freehand, side-fire systematic prostate biopsy (sPBx) with the goal of reducing prostate biopsy (PBx) false-negatives, thereby facilitating earlier sampling, diagnosis and treatment of clinically significant prostate cancer.

Participants And Methods: Using a PBx simulator with real-time three-dimensional visualization, we devised a freehand, pitch-neutral (0°, horizontal plane), side-fire, transrectal ultrasonography (TRUS)-guided sPBx technique in the left lateral decubitus position. Thirty-four trainees on four Canadian and US urology programmes learned the technique on the same simulator, which recorded deviation from the intended template location in a double-sextant template as well as the TRUS probe pitch at the time of sampling.

Mechanosensory Signaling in Astrocytes.

Mechanosensitivity is a well-known feature of astrocytes, however, its underlying mechanisms and functional significance remain unclear. There is evidence that astrocytes are acutely sensitive to decreases in cerebral perfusion pressure and may function as intracranial baroreceptors, tuned to monitor brain blood flow. This study investigated the mechanosensory signaling in brainstem astrocytes, as these cells reside alongside the cardiovascular control circuits and mediate increases in blood pressure and heart rate induced by falls in brain perfusion.
