Maternal microchimeric cell trafficking and its biological consequences depend on the onset of inflammation at the feto-maternal interface.

Microchimerism is defined as the presence of a small population of genetically distinct cells within a host that is derived from another individual. Throughout pregnancy, maternal and fetal cells are known to traffic across the feto-maternal interface and result in maternal and fetal microchimerism, respectively. However, the routes of cell transfer, the molecular signaling as well as the timing in which trafficking takes place are still not completely understood.

Decreasing miR-433-3p activity in the osteoblast lineage blunts glucocorticoid-mediated bone loss.

Glucocorticoid excess causes bone loss due to decreased bone formation and increased bone resorption; miR-433-3p is a miRNA that negatively regulates bone formation in male mice by targeting Runx2 as well as RNAs involved in Wnt, protein kinase A and endogenous glucocorticoid signaling. To examine the impact of miR-433-3p on glucocorticoid-mediated bone loss, transgenic mice expressing a miR-433-3p tough decoy inhibitor in the osteoblast lineage were administered prednisolone via slow-release pellets. Bone loss was greater in control mice treated with prednisolone compared with miR-433-3p tough decoy mice due to higher osteoclast activity in the controls.

SmERF6 Promotes the Expression of Terpenoid Pathway in Salvia officinalis and Improves the Production of High Value Abietane Diterpenes, Carnosol and Carnosic acid.

Carnosol (CO) and carnosic acid (CA) are pharmaceutically important diterpenes predominantly produced in members of Lamiaceae, Salvia officinalis (garden sage), Salvia fruticosa and Rosmarinus officinalis. Nevertheless, availability of these compounds in plant system is very low. In an effort to improve the in planta content of these diterpenes in garden sage, SmERF6 (Salvia miltiorrhiza Ethylene Responsive Factor 6) transcription factor was expressed heterologously.

An exosome-based liquid biopsy predicts depth of response and survival outcomes to cetuximab and panitumumab in metastatic colorectal cancer: The EXONERATE Study.

PURPOSE EXONERATE (EXOsome and cell-free micro-RNAs of anti-EGFR ResistAnce) was an open-label, biomarker interventional study designed to develop, test, and validate a liquid biopsy predictive of progression-free survival (PFS), overall survival (OS), and objective response rate (ORR) for first-line EGFR inhibitors in metastatic colorectal cancer (mCRC). PATIENTS AND METHODS Patients with newly diagnosed RAS-WT, chemotherapy-naïve mCRC, both right- and left-sided, were enrolled in 2-nationwide trials to receive cetuximab or panitumumab along with chemotherapy. The primary endpoint was 12-month PFS, which was hierarchically tested in left- and right-sided mCRC to predict PFS, OS, and ORR.

Postnatal management of preterm infants with congenital diaphragmatic hernia.

Introduction: Congenital diaphragmatic hernia (CDH) in the preterm population is increasingly common in the current era of fetal endoluminal tracheal occlusion (FETO) therapy. There remains a lack of clinical guidance for clinicians and surgeons regarding optimal management strategies for such infants. We aimed to describe our experience in managing preterm CDH in a single quaternary neonatal intensive care unit (NICU).

Doxorubicin treatment has a biphasic effect over time on dopamine release and impulsive behavior in Wistar rats.

Doxorubicin (Dox) is a chemotherapy agent commonly used to treat multiple types of cancers and is associated with cognitive impairment. The goal of this work was to determine the effect of Dox treatment on dopamine release and uptake and behavior in rats. Rats received one dose per week of Dox (2.

Feasibility and acceptability of a mindfulness app-based intervention among patients with metastatic renal cell carcinoma: a multinational study.

The purpose of this study was to investigate patient experience in the radiation department during COVID-19 and compare results to previous data collected in 2019.

Methods: Patient experience data was collected using the Your Voice Matters (YVM) survey.

Recommendations for mitochondria transfer and transplantation nomenclature and characterization.

Intercellular mitochondria transfer is an evolutionarily conserved process in which one cell delivers some of their mitochondria to another cell in the absence of cell division. This process has diverse functions depending on the cell types involved and physiological or disease context. Although mitochondria transfer was first shown to provide metabolic support to acceptor cells, recent studies have revealed diverse functions of mitochondria transfer, including, but not limited to, the maintenance of mitochondria quality of the donor cell and the regulation of tissue homeostasis and remodelling.

Pregnancy entails a U-shaped trajectory in human brain structure linked to hormones and maternal attachment.

Growing evidence places the gestational period as a unique moment of heightened neuroplasticity in adult life. In this longitudinal study spanning pre, during, and post pregnancy, we unveil a U-shaped trajectory in gray matter (GM) volume, which dips in late pregnancy and partially recovers during postpartum. These changes are most prominent in brain regions associated with the Default Mode and Frontoparietal Network.

Genome-wide association study of urinary cadmium levels in current smokers from the multiethnic cohort study.

Background: Cadmium (Cd), classified as an International Agency for Research on Cancer (IARC) Group 1 human carcinogen, is present in cigarette smoke. Recent studies have illustrated the potential role of genetics in influencing Cd biomarker levels.

Methods: We conducted a genome-wide association study (GWAS) of urinary Cd levels in 1977 current smokers from the Multiethnic Cohort Study, comprising participants from five different racial and ethnic groups.

Social inequalities in youth mental health in Canada, 2007-2022: a population-based repeated cross-sectional study.

Purpose: Rising concern surrounds youth mental health in Canada, with growing disparities between females and males. However, less is known about recent trends by other sociodemographic factors, including sexual orientation, ethnocultural background, and socioeconomic status.

Methods: This study analyzed data from 96 683 youths aged 15-24 who participated in the nationally representative Canadian Community Health Survey (CCHS) between 2007 and 2022.

Brief exposure to (-) THC affects zebrafish embryonic locomotion with effects that persist into the next generation.

Cannabis is one of the most widely used drugs, and yet an understanding of its impact on the human brain and body is inconclusive. Medicinal and recreational use of cannabis has increased in the last decade with a concomitant increase in use by pregnant women. The major psychoactive compound in cannabis, Δ-tetrahydrocannabinol (THC), exists in different isomers, with the (-) trans isomer most common.

Sex-specific response of intramuscular fat to diet-induced obesity in rats.

Metabolic abnormalities associated with excess adiposity in obesity contribute to many noncommunicable diseases, including sarcopenic obesity. Sarcopenic obesity is the loss of muscle mass coupled with excess fat mass and fatty infiltrations in muscle tissue called myosteatosis. A diet-induced obesity model was developed to study fat infiltration in muscle tissue.

Change Over Time in Hospital Care for Medicaid Beneficiaries: Analysis of Hospitalizations from 2016-2019.

Background: Historically, access to high-quality care has been a central challenge for Medicaid programs. Prior single-year analyses demonstrated that Medicaid beneficiaries account for disproportionately high patient volumes at low-quality hospitals. Given major Medicaid shifts including expansion and increased managed care, we examined recent trends in low-quality hospital use for Medicaid beneficiaries.

Functional test of a naturally occurred tumor modifier gene provides insights to melanoma development.

Occurrence of degenerative interactions is thought to serve as a mechanism underlying hybrid unfitness in most animal systems. However, the molecular mechanisms underpinning the genetic interaction and how they contribute to overall hybrid incompatibilities are limited to only a handful of examples. A vertebrate model organism, Xiphophorus, is used to study hybrid dysfunction, and it has been shown from this model that diseases, such as melanoma, can occur in certain interspecies hybrids.

Enhanced neurogenesis after ischemic stroke: the interplay between endogenous and exogenous stem cells.

Ischemic stroke is a significant global health crisis, frequently resulting in disability or death, with limited therapeutic interventions available. Although various intrinsic reparative processes are initiated within the ischemic brain, these mechanisms are often insufficient to restore neuronal functionality. This has led to intensive investigation into the use of exogenous stem cells as a potential therapeutic option.

VEXAS syndrome: is it more a matter of inflammation or hematopoietic clonality? A case series approach to diagnosis, therapeutic strategies and transplant management.

VEXAS syndrome is a complex hemato-inflammatory disorder, driven by somatic mutations in the UBA1 gene within hematopoietic precursor cells. It is characterized by systemic inflammation, rheumatological manifestations, and frequent association with myelodysplastic syndrome (MDS). We present a series of four VEXAS cases, all of which include concomitant MDS, each displaying distinct genetic signatures and clinical features at diagnosis, with a focus on their diagnostic and therapeutic implications.

An activity concentration-based proposal for radon management in workplaces involving NORM in Canada.

The Canadian Guidelines for the Management of Naturally Occurring Radioactive Materials (NORM) have been developed to manage radiation doses received in workplaces involving NORM, such as mineral extraction and processing, oil and gas production, metal recycling or water treatment facilities. This management strategy works well for most naturally occurring radioactive materials in workplaces, with the exception of radon. Radon is a naturally occurring radioactive gas generated by the decay of uranium-bearing minerals in rocks and soils.

RSK1 is an exploitable dependency in myeloproliferative neoplasms and secondary acute myeloid leukemia.

Myeloid malignancies are heterogenous disorders characterized by distinct molecular drivers but share convergence of oncogenic signaling pathways and propagation by ripe pro-inflammatory niches. Here, we establish a comprehensive transcriptional atlas across the spectrum of myeloproliferative neoplasms (MPN) and secondary acute myeloid leukemia (sAML) through RNA-sequencing of 158 primary samples encompassing CD34+ hematopoietic stem/progenitor cells and CD14+ monocytes. Supported by mass cytometry (CyTOF) profiling, we reveal aberrant networks of PI3K/AKT/mTOR signalling and NFκB-mediated hyper-inflammation.

Parental loss at age 0-21 and daughters' breast cancer and tumor characteristics.

Background: Adverse events in childhood are linked to cancer risk across the life course, but evidence is lacking regarding parental death during childhood and breast cancer (BrCa) characteristics. We investigated whether parental loss in childhood defines women at higher risk of BrCa incidence and aggressive disease.

Methods: The Child Health and Development Studies (CHDS) comprises over 15,000 families who enrolled during mothers' pregnancies between 1959-1967; family members were followed for cancer incidence and cause-specific mortality.
