An accessible digital imaging workflow for multiplexed quantitative analysis of adult eye phenotypes in .

The compound eye of has long been a model for studying genetics, development, neurodegeneration, and heterochromatin. Imaging and morphometry of adult and other insects is hampered by the low throughput, narrow focal plane, and small image sensors typical of stereomicroscope cameras. When data collection is distributed among many individuals or extended time periods, these limitations are compounded by inter-operator variability in lighting, sample positioning, focus, and post-acquisition processing.

Analysis of the northern pitcher plant (Sarracenia purpurea L.) phytotelm bacteriome throughout a temperate region growing season.

The insectivorous Northern Pitcher Plant, Sarracenia purpurea, recruits a dynamic biotic community in the rainwater collected by its pitcher-shaped leaves. Insect capture and degradation within the pitcher fluid (phytotelma) has been well documented as a mechanism for supplementing the plant's nitrogen, phosphorous, and micronutrient requirements. Metagenomic studies have shown a diverse microbiome in this phytotelm environment, including taxa that contribute metabolically to prey digestion.

The Role of Atypical Chemokine Receptors in Neuroinflammation and Neurodegenerative Disorders.

Neuroinflammation is associated with several neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), and multiple sclerosis (MS). Neuroinflammation provides protection in acute situations but results in significant damage to the nervous system if chronic. Overexpression of chemokines within the brain results in the recruitment and activation of glial and peripheral immune cells which can propagate a cascading inflammatory response, resulting in neurodegeneration and the onset of neurodegenerative disorders.

Multiomic analysis reveals conservation of cancer-associated fibroblast phenotypes across species and tissue of origin.

Cancer-associated fibroblasts (CAFs) are integral to the solid tumor microenvironment. CAFs were once thought to be a relatively uniform population of matrix-producing cells, but single-cell RNA sequencing has revealed diverse CAF phenotypes. Here, we further probed CAF heterogeneity with a comprehensive multiomics approach.

Humans can navigate complex graph structures acquired during latent learning.

Humans appear to represent many forms of knowledge in associative networks whose nodes are multiply connected, including sensory, spatial, and semantic. Recent work has shown that explicitly augmenting artificial agents with such graph-structured representations endows them with more human-like capabilities of compositionality and transfer learning. An open question is how humans acquire these representations.

Quality of Life and Symptom Management in Advanced Biliary Tract Cancers.

Biliary tract carcinomas (BTCs) account for less than 1% of all cancers but are increasing in incidence. Prognosis is poor for BTC patients, with 5-year survival rates of less than 10%. While chemotherapy has been the mainstay treatment for patients with advanced BTC, immunotherapy and targeted therapies are being evaluated in numerous clinical trials and rapidly incorporated into clinical practice.

Increased and biased deliberation in social anxiety.

A goal of computational psychiatry is to ground symptoms in basic mechanisms. Theory suggests that avoidance in anxiety disorders may reflect dysregulated mental simulation, a process for evaluating candidate actions. If so, these covert processes should have observable consequences: choices reflecting increased and biased deliberation.

Context-sensitive valuation and learning.

A variety of behavioral and neural phenomena suggest that organisms evaluate outcomes not on an absolute utility scale, but relative to some dynamic and context-sensitive reference or scale. Sometimes, as in foraging tasks, this results in sensible choices; in other situations, like choosing between options learned in different contexts, irrational choices can result. We argue that what unites and demystifies these various phenomena is that the brain's goal is not assessing utility as an end in itself, but rather comparing different options to choose the better one.

Impact of a Medical Diagnosis on Decision to Stop Smoking and Successful Smoking Cessation.

Introduction: Smoking cessation counseling is a central part of the Medicare guidelines for lung cancer screening. With increasing age, many heavy smokers eventually stop smoking, however, factors influencing the decision to stop smoking are poorly understood. We postulated that declining health or physician-diagnosis of a medical condition may be associated with successful smoking cessation.

Vitamin D deficiency cardiomyopathy in Scotland: a retrospective review of the last decade.

Objective: To determine the incidence, demography and prognosis of vitamin D deficiency dilated cardiomyopathy (DCM) in Scotland over the last decade.

Study Design: A retrospective review of cases of vitamin D deficiency DCM presenting to a national paediatric cardiac centre between 1 January 2008 and 1 January 2018. The departmental database and electronic and paper case notes were used to identify patients and extract data.

First-line pembrolizumab therapy in a cisplatin-ineligible patient with plasmacytoid urothelial carcinoma: A case report.

Background: Plasmacytoid urothelial carcinoma (PUC) is a rare but aggressive variant of transitional cell carcinoma. In patients with unresectable disease, cisplatin-based combination chemotherapy is the most commonly used treatment. However, many patients are cisplatin-ineligible due to poor performance status or other comorbidities.

Stimulus generalization as a mechanism for learning to trust.

How do humans learn to trust unfamiliar others? Decisions in the absence of direct knowledge rely on our ability to generalize from past experiences and are often shaped by the degree of similarity between prior experience and novel situations. Here, we leverage a stimulus generalization framework to examine how perceptual similarity between known individuals and unfamiliar strangers shapes social learning. In a behavioral study, subjects play an iterative trust game with three partners who exhibit highly trustworthy, somewhat trustworthy, or highly untrustworthy behavior.

Altered pupillary light response scales with disease severity in migrainous photophobia.

Background Autonomic dysfunction and light sensitivity are core features of the migraine attack. Growing evidence also suggests changes in these parameters between attacks. Though sensory and autonomic responses likely interact, they have not been studied together across the spectrum of disease in migraine.

Episodic memories predict adaptive value-based decision-making.

Prior research illustrates that memory can guide value-based decision-making. For example, previous work has implicated both working memory and procedural memory (i.e.

Amelogenesis Imperfecta with Coronal Resorption: Report of Three Cases.

Intracoronal resorption of the permanent dentition in cases of amelogenesis imperfecta (AI) is a rare finding which poses an added complication to the already complex management of this condition. This paper presents three cases of AI associated with delayed eruption of permanent teeth in which asymptomatic intracoronal resorption occurred. CPD/Clinical Relevance: This paper highlights the fact that teeth affected with amelogenesis imperfecta may undergo asymptomatic intracoronal resorption which is only identifiable radiographically.

Human Obesity Associated with an Intronic SNP in the Brain-Derived Neurotrophic Factor Locus.

Brain-derived neurotrophic factor (BDNF) plays a key role in energy balance. In population studies, SNPs of the BDNF locus have been linked to obesity, but the mechanism by which these variants cause weight gain is unknown. Here, we examined human hypothalamic BDNF expression in association with 44 BDNF SNPs.

Acute and subacute complications of pediatric and adolescent knee arthroscopy.

Purpose: The purposes of this study were to determine the frequency of acute and subacute complications (within 6 months) of arthroscopic knee procedures in patients aged 17 years or younger and to determine associated risk factors.

Methods: We identified all patients aged 17 years or younger who underwent arthroscopic knee procedures at our institution from 1997 to 2009. Patient demographic and surgical data were collected from the medical and surgical records, with specific focus on intraoperative and postoperative complications.

Effect of running retraining on pain, function, and lower-extremity biomechanics in a female runner with iliotibial band syndrome.

Context: Iliotibial-band syndrome (ITBS) is a common overuse running injury. There is inconclusive evidence to support current management strategies, and few advances have been made in the past few years. New management approaches should thus be developed and evaluated.

Characteristics of child dental neglect: a systematic review.

Objective: Neglect of a child's oral health can lead to pain, poor growth and impaired quality of life. In populations where there is a high prevalence of dental caries, the determination of which children are experiencing dental neglect is challenging. This systematic review aims to identify the features of oral neglect in children.

Impact of implementing mental health screening by mail with a primary care management model.

Background: Early recognition and treatment of social and emotional disorders in children is significant for school preparation. These disorders are frequently underdetected without the use of standardized screening instruments. The purpose of our study is to describe the implementation of the Ages and Stages Questionnaire: Social-Emotional (ASQ:SE) in primary care practice by mail when children are 30 months old.

Children's understandings and motivations surrounding novelty sweets: a qualitative study.

Background: Novelty sweets resemble or can be used as toys, are brightly coloured, with striking imagery, and sold at pocket money prices. They encourage regular consumption as packaging can be resealed, leading to prolonged exposure of these high-sugar and low pH products to the oral tissues, risk factors for dental caries and erosion, respectively.

Aim: To determine how children conceptualise novelty sweets and their motivations for buying and consuming them.
