Delayed Tooth Development and the Impaired Differentiation of Stem/Progenitor Cells in Incisors from Type 2 Diabetes Mice.

Patients with diabetes mellitus (DM) have an increased risk of tooth decay caused by alterations in their tooth development and their oral environment, as well as a tendency to present with pulp infection due to compromised immune response. The present study analyzed the characteristic alterations in tooth development under DM conditions using incisors from type 2 diabetic mouse model (T2DM mice). In micro-CT analyses, T2DM mice showed delayed dentin and enamel formation.

Genomic reconstruction reveals impact of population management strategies on modern Galápagos dogs.

Free-breeding dogs have occupied the Galápagos Islands at least since the 1830s; however, it was not until the 1900s that dog populations grew substantially, endangering wildlife and spreading disease. In 1981, efforts to control the population size of free-roaming dogs began. Yet, there exist large free-roaming dog populations on the islands of Isabela and Santa Cruz whose ancestry has never been assessed on a genome-wide scale.

Practical considerations in the establishment of psychedelic research programs.

Rationale: There is increasing interest in establishing psychedelic research programs at academic medical centers. However, psychedelics are intensely psychoactive, carry considerable sociopolitical baggage, and most are Schedule I drugs, creating significant potential impediments to implementation. There is little formal guidance for investigators on navigating the complex on-the-ground obstacles associated with establishing psychedelic research programs.

Diagnosis and hybrid interventional and surgical removal of ectopic heartworms (Dirofilaria immitis) in a dog.

An adult male castrated French bulldog mix was presented for suspected caval syndrome and bilateral pelvic limb paresis. After emergency transjugular heartworm extraction, abdominal ultrasound revealed occlusive adult heartworms in the abdominal aorta extending into the pelvic limb arteries. Hybrid interventional and surgical extraction was pursued, and heartworms were removed via bilateral femoral arteriotomy and caudal abdominal aortotomy.

Installation of Copper(I) and Silver(I) Sites into TREN-Based Porous Organic Cages via Postsynthetic Metalation.

Porous organic cages (POCs) and metal-organic polyhedra (MOPs) function as zero-dimensional porous materials, able to mimic many functions of insoluble framework materials while offering processability advantages. A popular approach to access tailored metal-based motifs in extended network materials is postsynthetic metalation, which allows metal installation to be decoupled from framework assembly. Surprisingly, this approach has only sparingly been reported for molecular porous materials.

Perinatal continuity of care for mothers with depressive symptoms: perspectives of mothers and clinicians.

Background: Mothers with mild to moderate depression in pregnancy are at risk of developing postpartum depression. Midwife-led continuity of care may support maternal mental health throughout the perinatal period. Research is needed to better understand how continuity of care may support mothers experiencing depression in pregnancy.

How to perform an electrocardiogram in an awake pond slider turtle (Trachemys scripta): a comparative study of five noninvasive methodologies.

Objective: To compare multiple noninvasive ECG methods in pond sliders based upon repeatability, ability to recognize standard waveforms, and measurability.

Methods: The study was performed from November 2023 through January 2024. Ten healthy adult pond turtles were enrolled in the study.

This study examined the associations between maternal depression and oxytocin in pregnancy, caregiving sensitivity and adult attachment style, and infant temperament. One hundred and six women recruited from a public hospital antenatal clinic in Australia, and their infants completed assessments at three time points (Time 1: pregnancy; Time 2: 3-month postpartum; Time 3: 12-month postpartum). Mothers completed self-report questionnaires assessing maternal depression symptom severity at Time 1-3, adult attachment style at Time 2, and infant temperament at Time 3.

Symbolic and non-symbolic representations of numerical zero in the human brain.

Representing the quantity zero as a symbolic concept is considered a unique achievement of abstract human thought. To conceptualize zero, one must abstract away from the (absence of) sensory evidence to construct a representation of numerical absence: creating "something" out of "nothing." Previous investigations of the neural representation of natural numbers reveal distinct numerosity-selective neural populations that overlap in their tuning curves with adjacent numerosities.

Hypertensive Emergency Secondary to Combining Psilocybin Mushrooms, Extended Release Dextroamphetamine-Amphetamine, and Tranylcypromine.

Data on medication interactions with psychedelics are limited. Here we present what may be the first published report of a hypertensive emergency following the combination of psilocybin mushrooms with a monoamine oxidase inhibitor (MAOI). A 42-year-old man with treatment-resistant major depressive disorder took 1 g of mushrooms, while prescribed tranylcypromine, extended-release dextroamphetamine-amphetamine, and other medications.

Comparison of Length of Stay Between Children Admitted to an Observation Versus Inpatient Unit.

Objectives: Many children who require hospitalization are ideal candidates for care in pediatric observation units (POUs) rather than inpatient pediatric units. Differences in outcomes between children cared for in these 2 practice settings have not been thoroughly evaluated.

Methods: In this retrospective cohort study, children aged 0 to 18 years admitted to a POU at a community hospital or inpatient unit at a children's hospital were enrolled if they met specific clinical criteria.

Selective adsorption of fluorinated super greenhouse gases within a metal-organic framework with dynamic corrugated ultramicropores.

Perfluorocompound (PFC) gases play vital roles in microelectronics processing. Requirements for ultra-high purities traditionally necessitate use of virgin sources and thereby hinder the capture, purification, and reuse of these costly gases. Most importantly, gaseous PFCs are incredibly potent greenhouse gases with atmospheric lifetimes on the order of 10-10 years, and thus any environmental emissions have an outsized and prolonged impact on our climate.

Understanding 2p core-level excitons of late transition metals by analysis of mixed-valence copper in a metal-organic framework.

The L-edge X-ray absorption spectra of late transition metals such as Cu, Ag, and Au exhibit absorption onsets lower in energy for higher oxidation states, which is at odds with the measured spectra of earlier transition metals. Time-dependent density functional theory calculations for Cu/Cu reveal a larger 2p core-exciton binding energy for Cu, overshadowing shifts in single-particle excitation energies with respect to Cu. We explore this phenomenon in a Cu metal-organic framework with ∼12% Cu defects and find that corrections with self-consistent excited-state total energy differences provide accurate XAS peak alignment.

Formulary Coverage of Esketamine and Ketamine for Depression in Ohio Health Insurance Marketplace and Medicaid Plans.

For more than 2 decades, intravenous ketamine has been demonstrated to have rapid antidepressant effects. However, access to this generic drug is limited due to insurers claiming it is "experimental" because ketamine does not have a Food and Drug Administration indication for depression. In contrast, intranasal esketamine, an enantiomer of ketamine, is approved by the Food and Drug Administration for depression and is still under patent.

Identifying content-invariant neural signatures of perceptual vividness.

Some conscious experiences are more vivid than others. Although perceptual vividness is a key component of human consciousness, how variation in this magnitude property is registered by the human brain is unknown. A striking feature of neural codes for magnitude in other psychological domains, such as number or reward, is that the magnitude property is represented independently of its sensory features.

Preexisting Psychiatric Conditions as Risk Factors for Diagnosed Long COVID-19 Syndrome Within Aggregated Electronic Health Record Data.

Objective: This study aimed to investigate the frequency of long COVID diagnosis among patients infected with severe acute respiratory syndrome coronavirus 2 with preexisting psychiatric conditions versus those without preexisting psychiatric conditions.

Methods: The TriNetX Analytics platform, an aggregated electronic health record research network containing the deidentified electronic health record data of more than 90 million patients, was queried for patients who were diagnosed with COVID-19 infection based on International Classifications of Disease, Tenth Revision codes. Patients were stratified based on their preexisting psychiatric conditions, and new diagnoses of long COVID were recorded and reported as the primary outcome.

Phencyclidine Positivity on Urine Drug Screening in Patients Treated for Alcohol Withdrawal on a Dual-diagnosis Medically Assisted Withdrawal Unit.

Objectives: Little contemporary research has explored phencyclidine (PCP) use in people with alcohol use disorder. Therefore, we sought to determine the prevalence of PCP positivity on urine toxicology screening among patients admitted for alcohol withdrawal, identify correlates of PCP positivity, and investigate PCP positivity's relationship to length of stay (LOS) and risk of facility readmission.

Methods: This was a retrospective study of patients admitted to a dual-diagnosis medically assisted withdrawal unit for alcohol withdrawal from 2014 to 2019.
