Operationalizing Equity, Inclusion, and Access in Research Practice at a Large Academic Institution.

Introduction: Healthcare advances are hindered by underrepresentation in prospective research; sociodemographic, data, and measurement infidelity in retrospective research; and a paucity of guidelines surrounding equitable research practices.

Objective: The Joint Research Practices Working Group was created in 2021 to develop and disseminate guidelines for the conduct of inclusive and equitable research.

Methods: Volunteer faculty and staff from two research centers at the University of Pennsylvania initiated a multi-pronged approach to guideline development, including literature searches, center-level feedback, and mutual learning with local experts.

Cell type specific transcriptomic differences in depression show similar patterns between males and females but implicate distinct cell types and genes.

Major depressive disorder (MDD) is a common, heterogenous, and potentially serious psychiatric illness. Diverse brain cell types have been implicated in MDD etiology. Significant sexual differences exist in MDD clinical presentation and outcome, and recent evidence suggests different molecular bases for male and female MDD.

Complications of Thyroidectomy and Learning Curve for Thyroid Surgeons: An Institutional Experience.

To study the complications of thyroidectomy and the various methods to be followed in the intra and post-operative period to prevent complications. It is a prospective study of 5 years and 9 months duration from 1/1/2015 to 31/9/2020 done in a tertiary care hospital. A total of 268 patients were included in this study.

Associations of psychiatric disease and ageing with FKBP5 expression converge on superficial layer neurons of the neocortex.

Identification and characterisation of novel targets for treatment is a priority in the field of psychiatry. FKBP5 is a gene with decades of evidence suggesting its pathogenic role in a subset of psychiatric patients, with potential to be leveraged as a therapeutic target for these individuals. While it is widely reported that FKBP5/FKBP51 mRNA/protein (FKBP5/1) expression is impacted by psychiatric disease state, risk genotype and age, it is not known in which cell types and sub-anatomical areas of the human brain this occurs.

Three-Dimensional Fruit Tissue Habitats for Culturing Caenorhabditis elegans.

Environmental factors influence many traits of biological interest, but reproducing an animal's natural habitat in a controlled laboratory environment is challenging. Environmental enrichment-adding complexity to the usually simplistic conditions under which laboratory animals are raised-offers a potential tool for better understanding biological traits while maintaining controlled laboratory conditions. For the model nematode Caenorhabditis elegans, the contrast between the natural environment and the laboratory conditions in which they are raised is enormous.

Extraction of nuclei from archived postmortem tissues for single-nucleus sequencing applications.

Single-cell and single-nucleus sequencing techniques are a burgeoning field with various biological, biomedical and clinical applications. Numerous high- and low-throughput methods have been developed for sequencing the RNA and DNA content of single cells. However, for all these methods, the key requirement is high-quality input of a single-cell or single-nucleus suspension.

A three-dimensional habitat for C. elegans environmental enrichment.

As we learn more about the importance of gene-environment interactions and the effects of environmental enrichment, it becomes evident that minimalistic laboratory conditions can affect gene expression patterns and behaviors of model organisms. In the laboratory, Caenorhabditis elegans is generally cultured on two-dimensional, homogeneous agar plates abundantly covered with axenic bacteria culture as a food source. However, in the wild, this nematode thrives in rotting fruits and plant stems feeding on bacteria and small eukaryotes.

Deep feature extraction of single-cell transcriptomes by generative adversarial network.

Motivation: Single-cell RNA-sequencing (scRNA-seq) offers the opportunity to dissect heterogeneous cellular compositions and interrogate the cell-type-specific gene expression patterns across diverse conditions. However, batch effects such as laboratory conditions and individual-variability hinder their usage in cross-condition designs.

Results: Here, we present a single-cell Generative Adversarial Network (scGAN) to simultaneously acquire patterns from raw data while minimizing the confounding effect driven by technical artifacts or other factors inherent to the data.

Single-nucleus transcriptomics of the prefrontal cortex in major depressive disorder implicates oligodendrocyte precursor cells and excitatory neurons.

Major depressive disorder (MDD) has an enormous impact on global disease burden, affecting millions of people worldwide and ranking as a leading cause of disability for almost three decades. Past molecular studies of MDD employed bulk homogenates of postmortem brain tissue, which obscures gene expression changes within individual cell types. Here we used single-nucleus transcriptomics to examine ~80,000 nuclei from the dorsolateral prefrontal cortex of male individuals with MDD (n = 17) and of healthy controls (n = 17).

An efficient wavelet and curvelet-based PET image denoising technique.

Positron emission tomography (PET) image denoising is a challenging task due to the presence of noise and low spatial resolution compared with other imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT). PET image noise can hamper further processing and analysis, such as segmentation and disease screening. The wavelet transform-based techniques have often been proposed for PET image denoising to handle isotropic (smooth details) features.

The role of deliberate practice in expert performance: revisiting Ericsson, Krampe & Tesch-Römer (1993).

We sought to replicate Ericsson, Krampe & Tesch-Römer's (Ericsson, Krampe & Tesch-Römer 1993 , 363-406) seminal study on deliberate practice. Ericsson . found that differences in retrospective estimates of accumulated amounts of deliberate practice corresponded to each skill level of student violinists.

Epigenetic markers in inflammation-related genes associated with mood disorder: a cross-sectional and longitudinal study in high-risk offspring of bipolar parents.

Bipolar disorder is highly heritable and typically onsets in late adolescence or early adulthood. Evidence suggests that immune activation may be a mediating pathway between genetic predisposition and onset of mood disorders. Building on a prior study of mRNA and protein levels in high-risk offspring published in this Journal, we conducted a preliminary examination of methylation profiles in candidate immune genes from a subsample of well-characterized emergent adult (mean 20 years) offspring of bipolar parents from the Canadian Flourish high-risk cohort.

Mu opioid receptors in the medial habenula contribute to naloxone aversion.

The medial habenula (MHb) is considered a brain center regulating aversive states. The mu opioid receptor (MOR) has been traditionally studied at the level of nociceptive and mesolimbic circuits, for key roles in pain relief and reward processing. MOR is also densely expressed in MHb, however, MOR function at this brain site is virtually unknown.

Nonlinear state feedback controller design for underactuated mechanical system: a modified block backstepping approach.

This paper presents the formulation of a novel block-backstepping based control algorithm to address the stabilization problem for a generalized nonlinear underactuated mechanical system. For the convenience of compact design, first, the state model of the underactuated system has been converted into the block-strict feedback form. Next, we have incorporated backstepping control action to derive the expression of the control input for the generic nonlinear underactuated system.

Lung fibrosis-associated surfactant protein A1 and C variants induce latent transforming growth factor β1 secretion in lung epithelial cells.

Missense mutations of surfactant proteins are recognized as important causes of inherited lung fibrosis. Here, we study rare and common surfactant protein (SP)-A1 and SP-C variants, either discovered in our familial pulmonary fibrosis cohort or described by others. We show that expression of two SP-A1 (R219W and R242*) and three SP-C (I73T, M71V, and L188Q) variant proteins lead to the secretion of the profibrotic latent transforming growth factor (TGF)-β1 in lung epithelial cell lines.

Mutant surfactant A2 proteins associated with familial pulmonary fibrosis and lung cancer induce TGF-β1 secretion.

Mutations in the genes encoding the lung surfactant proteins are found in patients with interstitial lung disease and lung cancer, but their pathologic mechanism is poorly understood. Here we show that bronchoalveolar lavage fluid from humans heterozygous for a missense mutation in the gene encoding surfactant protein (SP)-A2 (SFTPA2) contains more TGF-β1 than control samples. Expression of mutant SP-A2 in lung epithelial cells leads to secretion of latent TGF-β1, which is capable of autocrine and paracrine signaling.
