EquiRank: Improved protein-protein interface quality estimation using protein language-model-informed equivariant graph neural networks.

Comput Struct Biotechnol J

December 2024

Department of Computer Science, Virginia Tech, Blacksburg, 24061, VA, USA.

Quality estimation of the predicted interaction interface of protein complex structural models is not only important for complex model evaluation and selection but also useful for protein-protein docking. Despite recent progress fueled by symmetry-aware deep learning architectures and pretrained protein language models (pLMs), existing methods for estimating protein complex quality have yet to fully exploit the collective potentials of these advances for accurate estimation of protein-protein interface. Here we present EquiRank, an improved protein-protein interface quality estimation method by leveraging the strength of a symmetry-aware E(3) equivariant deep graph neural network (EGNN) and integrating pLM embeddings from the pretrained ESM-2 model.

Alterations to the excitation/inhibition (E/I) ratio are postulated to underlie behavioral phenotypes in autism spectrum disorder (ASD) patients and mouse models. However, in wild type mice the E/I ratio is not constant, but instead oscillates across the 24-h day. Therefore, we tested whether E/I regulation, rather than the overall E/I ratio, is disrupted in two ASD-related mouse lines: KO and BTBR, models of syndromic and idiopathic ASD, respectively.

A Longitudinal Investigation of Trans and Nonbinary Youth Identity: Individual Processes and Family Agreement in the Trans Teen and Family Narratives Project.

LGBTQ Fam

June 2024

Division of Adolescent/Young Adult Medicine, Boston Children's Hospital, Department of Pediatrics, Harvard Medical School, Department of Social and Behavioral Sciences, Harvard T. H. Chan School of Public Health, 300 Longwood Ave, Boston, MA 02115.

Few studies have focused on transgender and nonbinary youths' (TNBY) gender development and even less well understood is how family members understand TNBY identity. The current study investigated: a) how TNBY describe their gender identity over time, and b) how family members understand TNBY gender identity over time. The baseline sample included 96 members of 33 families (33 TNBY, 48 cisgender caregivers, 15 siblings) from the United States; 30 families continued after Wave 1.

Background: The TaqMan Array Card (TAC) is an arrayed, high-throughput qPCR platform that can simultaneously detect multiple targets in a single reaction. However, the manual post-run analysis of TAC data is time consuming and subject to interpretation. We sought to automate the post-run analysis of TAC data using machine learning models.

Neuromodulating Alkaloids from Millipede Defensive Secretions.

J Nat Prod

January 2025

Department of Chemistry, Virginia Tech, Blacksburg, Virginia 24061, United States.

Millipedes have long been known to produce structurally diverse chemical defenses, including hydrogen cyanide, terpenoid alkaloids, and oxidized aromatics. Although the hydrogen cyanide and oxidized aromatic producing millipedes have been well studied, less than 10% of the terpenoid alkaloid producers have been chemically investigated. Several previous studies have shown that alkaloids disorient predators, but their biochemical target is currently unknown.

Background: Acute lung injury and acute respiratory failure are frequent complications of cardiogenic shock and are associated with increased morbidity and mortality. Even with increased use of temporary mechanical circulatory support, such as venoarterial extracorporeal membrane oxygenation (VA-ECMO), acute lung injury related to cardiogenic shock continues to have a determinantal effect on patient outcomes.

Objectives: To summarize potential mechanisms of acute lung injury described in patients with cardiogenic shock supported by VA-ECMO and determine current knowledge gaps.

Currently, the World Health Organization (WHO) grade of meningiomas is determined based on the biopsy results. Therefore, accurate non-invasive preoperative grading could significantly improve treatment planning and patient outcomes. Considering recent advances in machine learning (ML) and deep learning (DL), this meta-analysis aimed to evaluate the performance of these models in predicting the WHO meningioma grade using imaging data.

Black Americans with Posttraumatic Stress Disorder have less access to mental healthcare compared to White Americans. Many factors contribute to this inequity, including broader disparities within the healthcare system driven by systemic racism, and an underutilization of mental health services by Black Americans due to provider bias and stigma around mental health care. These disparities are rooted in a racist historical context of exclusion and abuse of the Black community by the White psychiatric establishment, and a perpetration of further trauma on Black clients, a context that is largely missing from traditional mental health education and literature on Black mental health today.

The optimal therapeutic intervention for pediatrics with optic pathway glioma (OPG) remained controversial in the literature. Recently, due to substantial adverse events (AEs) of chemotherapy and its impact on children's lives, the efficacy of other options has been investigated. Bevacizumab (BVZ) is an anti-vascular endothelial growth factor (VEGF) agent that alters the lesion microenvironment.

Diagnosis of cryptococcal meningitis is typically aided through CSF analysis obtained via lumbar puncture (LP), revealing elevated WBCs, increased protein, decreased glucose, and increased opening pressure. While CSF culture confirms the diagnosis, it takes days, prompting reliance on these adjuncts. AIDS from Human Immunodeficiency Virus is less commonly diagnosed in the emergency setting due to advances in testing and treatment.

Oppenauer-type oxidations are catalyzed by air- and moisture-stable, sustainable, (cyclopentadienone)iron carbonyl compounds, but the substrate scope is limited due to the low reduction potential of acetone, which is the most commonly used hydrogen acceptor. We discovered that furfural, an aldehyde derived from cellulosic biomass, is an effective hydrogen acceptor with this class of catalysts. In general, reactions using furfural as the hydrogen acceptor led to higher isolated yields of ketones and aldehydes compared to those using acetone.

Importance: The effect of adjuvant chemotherapy following resection of pancreatic adenocarcinoma after preoperative (m)FOLFIRINOX (combination leucovorin calcium [folinic acid], fluorouracil, irinotecan hydrochloride, and oxaliplatin in full or modified dosing) chemotherapy on overall survival (OS) is unclear because current studies do not account for the number of cycles of preoperative chemotherapy and adjuvant chemotherapy regimen.

Objective: To investigate the association of adjuvant chemotherapy following resection of pancreatic adenocarcinoma after preoperative (m)FOLFIRINOX with OS, taking into account the number of cycles of preoperative chemotherapy and adjuvant chemotherapy regimen.

Design, Setting, And Participants: This retrospective cohort study included patients with localized pancreatic adenocarcinoma treated with 2 to 11 cycles of preoperative (m)FOLFIRINOX followed by resection across 48 centers in 20 countries from 2010 to 2018.
