North American avian species that migrate in flocks show greater long-term non-breeding range shift rates.

Background: Many species are exhibiting range shifts associated with anthropogenic change. For migratory species, colonisation of new areas can require novel migratory programmes that facilitate navigation between independently-shifting seasonal ranges. Therefore, in some cases range-shifts may be limited by the capacity for novel migratory programmes to be transferred between generations, which can be genetically and socially mediated.

Synthesis of Lewis Acid-Base Adducts Between Potassium Dihydrogenpnictogenides and Group 13 Lewis Acids.

Lewis acid-base adducts between potassium dihydrogenpnictogenides [K(18c6)PnH] (Pn=P, As) and Trialkylgallanes (GaMe, GaEt, GatBu) as well as BH were synthesized. In the course of these investigations, we were able to fully characterize a row of compounds of the type [K(18c6)(thf)][PnH(ER)] (E=B: R=H; E=Ga: R=Me, Et, tBu). Based on the successful syntheses of these species, we also synthesized several compounds of the composition [K(18c6)(thf)][Pn(SiMe)(ER)] (n=1, 2) starting from [KPn(SiMe)] (Pn=P and As) and ER (E=B, Al, In: R=Me; E=Ga: R=Me, Et, tBu).

Editorial: Understanding Adolescent Mental Health Disparities Through the Lens of Environmental Stress Exposure.

Increasing evidence suggests that, as in other medical fields, there are pronounced pediatric mental health disparities with greater burden among marginalized racial and ethnic youth. The reasons for these disparities are not fully understood. One way to explain pediatric mental health disparities is through the lens of environmental stress as a driver of mental health burden, given that marginalized populations are exposed to more structural and individual stress.

A Dedicated Outpatient Pharmacy Improves Access to Discharge Medications in a Pediatric Emergency Department: A Quality Improvement Study.

Study Objective: Following discharge from a pediatric emergency department (ED) or urgent care, many families do not pick up their prescribed medications. The aim of this quality improvement study was to increase the percentage of patients discharged home with medications in-hand from 6% to 30% within 6 months.

Methods: Due to the planned construction of a new ED, urgent care, and dedicated pharmacy, a multidisciplinary team was formed to increase access to discharge medications.

Nickel-Catalyzed Reductive Arylation of Redox Active Esters for the Synthesis of α-Aryl Nitriles: Investigation of a Chlorosilane Additive.

A nickel-catalyzed reductive cross-coupling of redox active -hydroxyphthalimide (NHP) esters and iodoarenes for the synthesis of α-aryl nitriles is described. The NHP ester substrate is derived from cyanoacetic acid, which allows for a modular synthesis of substituted α-aryl nitriles, an important scaffold in the pharmaceutical sciences. The reaction exhibits a broad scope, and many functional groups are compatible under the reaction conditions, including complex highly functionalized medicinal agents.

Description of the Proton-Decaying 0_{2}^{+} Resonance of the α Particle.

The recent precise experimental determination of the monopole transition form factor from the ground state of ^{4}He to its 0_{2}^{+} resonance via electron scattering has reinvigorated discussions about the nature of this first excited state of the α particle. The 0_{2}^{+} state has been traditionally interpreted in the literature as the isoscalar monopole resonance (breathing mode) or, alternatively, as a particle-hole shell-model excitation. To better understand the nature of this state, which lies only ∼410  keV above the proton emission threshold, we employ the coupled-channel representation of the no-core Gamow shell model.

Strong Evidence for ^{9}N and the Limits of Existence of Atomic Nuclei.

The boundaries of the chart of nuclides contain exotic isotopes that possess extreme proton-to-neutron asymmetries. Here we report on strong evidence of ^{9}N, one of the most exotic proton-rich isotopes where more than one half of its constitute nucleons are unbound. With seven protons and two neutrons, this extremely proton-rich system would represent the first-known example of a ground-state five-proton emitter.

Femoral cartilage ultrasound echo-intensity is a valid measure of cartilage composition.

This study aimed to create a conversion equation that accurately predicts cartilage magnetic resonance imaging (MRI) T2 relaxation times using ultrasound echo-intensity and common participant demographics. We recruited 15 participants with a primary anterior cruciate ligament reconstruction between the ages of 18 and 35 years at 1-5 years after surgery. A single investigator completed a transverse suprapatellar scan with the ACLR limb in max knee flexion to image the femoral trochlea cartilage.

Study of terbium production from enriched Gd targets via the reaction Gd(d,2n)Tb.

The terbium (Tb) family has attracted much attention in recent years thanks to the diagnostic and therapeutic applications of the quadruplet Tb, Tb, Tb and Tb. However, the scarce availability of Tb radioisotopes is one of the main reasons hindering its clinical applications. To increase its availability, this work proposes to use enriched gadolinium (Gd) targets to produce some Tb radioisotopes (Tb, Tb, and Tb) via deuteron-induced reactions in cyclotrons.

Stand-alone kyphoplasty in recent thoracolumbar split fractures: A series of 36 patients reviewed at 19months.

Introduction: Spinal fractures with a split component present specific bone union problems (pseudarthrosis). The purpose of this study was to assess the rate of pseudarthrosis after stand-alone percutaneous kyphoplasties and analyze clinical and radiographic parameters that are predictive of its efficacy in thoracolumbar spine fractures with a split-type of injury.

Hypothesis: Stand-alone kyphoplasty results in satisfactory bone union of the treated vertebral body despite the diastasis of fracture fragments.

Effects of diversity on thermal niche variation in bird communities under climate change.

Climate change alters ecological communities by affecting individual species and interactions between species. However, the impacts of climate change may be buffered by community diversity: diverse communities may be more resistant to climate-driven perturbations than simple communities. Here, we assess how diversity influences long-term thermal niche variation in communities under climate change.

Therapeutic efficacy of Holmium siloxane in microbrachytherapy of induced glioblastoma in minipig tumor model.

Glioblastoma is considered the most common malignant primary tumor of central nervous system. In spite of the current standard and multimodal treatment, the prognosis of glioblastoma is poor. For this reason, new therapeutic approaches need to be developed to improve the survival time of the glioblastoma patient.

Modeled distribution shifts of North American birds over four decades based on suitable climate alone do not predict observed shifts.

As climate change alters the global environment, it is critical to understand the relationship between shifting climate suitability and species distributions. Key questions include whether observed changes in population abundance are aligned with the velocity and direction of shifts predicted by climate suitability models and if the responses are consistent among species with similar ecological traits. We examined the direction and velocity of the observed abundance-based distribution centroids compared with the model-predicted bioclimatic distribution centroids of 250 bird species across the United States from 1969 to 2011.

Ischemic Preconditioning and Postconditioning Protect the Heart by Preserving the Mitochondrial Network.

Background: Mitochondria fuse to form elongated networks which are more tolerable to stress and injury. Ischemic pre- and postconditioning (IPC and IPost, respectively) are established cardioprotective strategies in the preclinical setting. Whether IPC and IPost modulates mitochondrial morphology is unknown.

The Ancients and the Moderns: Chasles on Euclid's lost and the pursuit of geometry.

Of Euclid's lost manuscripts, few have elicited as much scholarly attention as the , of which a couple of brief summaries by late-Antiquity commentators are extant. Despite the lack of textual sources, attempts at restoring the content of this absent volume became numerous in early-modern Europe, following the diffusion of ancient mathematical manuscripts preserved in the Arabic world. Later, one similar attempt was that of French geometer Michel Chasles (1793-1880).

Transcription-associated DNA DSBs activate p53 during hiPSC-based neurogenesis.

Neurons are overproduced during cerebral cortical development. Neural progenitor cells (NPCs) divide rapidly and incur frequent DNA double-strand breaks (DSBs) throughout cortical neurogenesis. Although half of the neurons born during neurodevelopment die, many neurons with inaccurate DNA repair survive leading to brain somatic mosaicism.

Effects of Short Term Adiponectin Receptor Agonism on Cardiac Function and Energetics in Diabetic Mice.

Objective: Impaired cardiac efficiency is a hallmark of diabetic cardiomyopathy in models of type 2 diabetes. Adiponectin receptor 1 (AdipoR1) deficiency impairs cardiac efficiency in non-diabetic mice, suggesting that hypoadiponectinemia in type 2 diabetes may contribute to impaired cardiac efficiency due to compromised AdipoR1 signaling. Thus, we investigated whether targeting cardiac adiponectin receptors may improve cardiac function and energetics, and attenuate diabetic cardiomyopathy in type 2 diabetic mice.

Electrochemical co-deposition of Ni-GdO for composite thin targets preparation: Production of Tb as a case study.

In the last years, Tb has attracted enormous interest due to its potential role in theranostics in nuclear medicine. To estimate its production yield, the aim of this study was to develop a method to prepare thin Gd-enriched-containing targets aimed at the Gd(d, 2n)Tb nuclear cross section measurement. To this end, the electrochemical co-deposition method has been chosen to manufacture Ni-GdO composite targets.
