What is missing from the sturgeon jaw: Developmental morphology of the upper jaw in Acipenser
J Anat. 2023 Sep 22. doi: 10.1111/joa.13953. Online ahead of print.ABSTRACTSturgeons belong to the family Acipenseridae, the most species-rich extant family of Acipenseriformes, a basal actinopterygian group of key importance in assessing the early radiations of the actinopterygians. At the same time, acipenseriforms display unique specializations in the morphology of the snout and jaws which make them a valuable model for studying evolutionary novelties. However, despite a long history of research, the homologies of the snout and the mandibular arch of acipenseriforms remain uncertain preventing further studies on the evo...

Detransition Narratives Trouble the Simple Attribution of Madness in Transantagonistic Contexts: A Qualitative Analysis of 16 Canadians' Experiences
Cult Med Psychiatry. 2023 Sep 22. doi: 10.1007/s11013-023-09838-0. Online ahead of print.ABSTRACTEmerging evidence suggests that transgender individuals are more likely than cisgender peers to receive a diagnosis with a primary mental disorder. Attributions of madness, though, may serve the social function of dismissing and discrediting transgender individual's self-perceptions. The narratives of individuals who stop or reverse an initial gender transition who also identify as living with mental health conditions can sometimes amplify these socio-political discourses about transgender people. Through a critical mental heal...

Hwiccewyrm trispiculum gen. et sp. nov., a new leptopleuronine procolophonid from the Late Triassic of southwest England
Anat Rec (Hoboken). 2023 Sep 21. doi: 10.1002/ar.25316. Online ahead of print.ABSTRACTThe fissure fill localities of southwest England and South Wales are well-known for preserving rich assemblages of predominantly small-bodied Late Triassic to Early Jurassic tetrapods, but many aspects of these assemblages remain contentious. The age of the Late Triassic fissures is disputed, with some lines of argument suggesting a latest Triassic (Rhaetian) age, whereas other evidence suggests they may be as old as Carnian. The fissures have been hypothesized by some workers to have formed on an archipelago, with island effects invoked ...

Telehealth as an Effective Care Delivery Method During the COVID-19 Pandemic for the Rhode Island Behavioral Health Population
This study investigated (1) if telehealth allowed for patients who seek mental health services to maintain visit frequency and (2) if subpopulations were less likely to utilize telehealth. We used descriptive statistics to analyze the change in total number of visits, in-person visits from pre-waiver to post-waiver, and a multivariate linear regression to identify relationships between demographics and telehealth utilization. Participants were able to maintain the frequency of visits during the COVID-19 pandemic. Race/ethnicity, age, gender, employment status, and housing status were all statistically significant predictor...

Epigenetic reprogramming of a distal developmental enhancer cluster drives SOX2 overexpression in breast and lung adenocarcinoma
Nucleic Acids Res. 2023 Sep 22:gkad734. doi: 10.1093/nar/gkad734. Online ahead of print.ABSTRACTEnhancer reprogramming has been proposed as a key source of transcriptional dysregulation during tumorigenesis, but the molecular mechanisms underlying this process remain unclear. Here, we identify an enhancer cluster required for normal development that is aberrantly activated in breast and lung adenocarcinoma. Deletion of the SRR124-134 cluster disrupts expression of the SOX2 oncogene, dysregulates genome-wide transcription and chromatin accessibility and reduces the ability of cancer cells to form colonies in vitro. Analysis...

Fructose-induced mTORC1 Activation Promotes Pancreatic Cancer Progression through Inhibition of Autophagy
In this study, we investigated the functional association between fructose utilization and pancreatic ductal adenocarcinoma (PDAC) progression. Fructose could be taken up and metabolized by PDAC cells and provided an adaptive survival mechanism for PDAC cells under glucose deficient conditions. GLUT5-mediated fructose metabolism maintained the survival, proliferation, and invasion capacities of PDAC cells in vivo and in vitro. Fructose metabolism not only provided ATP and biomass to PDAC cells but also conferred metabolic plasticity to the cells, making them more adaptable to the tumor microenvironment. Mechanistically, fr...

Galectin-3 Cooperates with CD47 to Suppress Phagocytosis and T cell Immunity in Gastric Cancer Peritoneal Metastases
Cancer Res. 2023 Sep 22. doi: 10.1158/0008-5472.CAN-23-0783. Online ahead of print.ABSTRACTThe peritoneal cavity is a common site of gastric adenocarcinoma (GAC) metastasis. Peritoneal carcinomatosis (PC) is resistant to current therapies and confer poor prognosis, highlighting the need to identify new therapeutic targets. CD47 conveys a "don't eat me" signal to myeloid cells upon binding its receptor SIRPα, which helps tumor cells circumvent macrophage phagocytosis and evade innate immune responses. Previous studies demonstrated that the blockade of CD47 alone results in limited clinical benefits, suggesting that other t...
