Adverse childhood experiences amplify the longitudinal associations of adult daily stress and health.

Child Abuse Negl 2021 Sep 21;122:105337. Epub 2021 Sep 21.

Human Development and Family Studies, The Pennsylvania State University, University Park, PA 16802, United States of America.

Background And Objective: The long-term negative impact of Adverse Childhood Experiences (ACEs) is now well-recognized; however, little research has explored the link between ACEs and daily stress processes in adulthood. The current study aimed to examine the effect of ACEs in the association between daily stressor exposure and daily negative affect, and whether such associations would predict long-term health and well-being.

Methods: Using data from the National Study of Daily Experiences 2 (NSDE 2) and the Midlife in the United States (MIDUS) studies, multilevel moderated mediation analyses were conducted to account for daily measurements nested within individuals. Read More

Increasing diagnostic possibilities using the geneLEAD VIII platform for detection of SARS-CoV-2.

J Virol Methods 2021 Sep 22:114291. Epub 2021 Sep 22.

Department of Medical Microbiology, Leiden University Medical Center, 2300 RC, Leiden, the Netherlands.

At the time SARS-CoV-2 was identified as the cause of coronavirus disease 2019 (COVID-19) no in vitro diagnostic (IVD) tests were available since it was a new virus. Very shortly after the release of the genomic sequence of SARS-CoV-2, laboratory-developed tests (LDTs) were developed, made available and implemented in several laboratories in the Netherlands and globally. In this study, the performance of an E-gene Sarbeco specific real-time reverse-transcriptase PCR (RT-PCR) was verified on the open modus of the geneLEAD VIII sample-to-answer platform. Read More

Clinical performance of methylation as a biomarker for cervical carcinoma-in-situ and cancer diagnosis: a worldwide study.

Int J Cancer 2021 Sep 25. Epub 2021 Sep 25.

Centre for Cancer Prevention, Wolfson Institute of Population Health Queen Mary University of London, Charterhouse Square, London, United Kingdom.

The shift towards primary HPV-based screening has necessitated the search for a secondary triage test that provides sufficient sensitivity to detect high grade cervical intraepithelial neoplasia (CIN) and cancer, but also brings an improved specificity to avoid unnecessary clinical work and colposcopy referrals. We evaluated the performance of the previously described DNA-methylation test (S5) in detecting CIN3 and cancers from diverse geographic settings in high, medium and low income countries, using the cut-off of 0.80 and exploratory cut-offs of 2.

Petroleum-Gas University of Ploiești, Bucharest Blvd. 39, 100680, Ploiești, Romania.

The hydrodesulphurization of a model component and equimolar ternary mixture of thiophene, 2-ethylthiophene and benzothiophene over sulphided CoMo/γ-AlO and CoMo/γ-AlO-NbO catalysts were investigated in a fixed bed flow reactor. The catalysts were prepared by incipient wetness impregnation method and characterized by textural characteristics, total acidity and chemical species present on the catalysts surface. The characterization results showed that both CoMo/γ-AlO-NbO and sulphided CoMo/γ-AlO catalysts exhibit a mesoporous structure with cylindrical pores open at both ends, evidenced by the IV type adsorption-desorption isotherm with a H1 hysteresis loop and have an average pore diameter between 3 and 4 nm.

β-arrestin-biased allosteric modulator potentiates Carvedilol stimulated β adrenergic receptor cardioprotection.

Mol Pharmacol 2021 Sep 24. Epub 2021 Sep 24.

Medicine, Duke University, United States

β adrenergic receptors (βARs) are central regulators of cardiac function and a drug target for cardiac disease. As a member of G protein-coupled receptor family, βARs activate cellular signaling by primarily coupling to Gs proteins to activate adenylyl cyclase and cAMP-dependent pathways, and the multifunctional adaptor-transducer protein β-arrestin. Carvedilol, a traditional β-blocker widely used in treating high blood pressure and heart failure by blocking βAR-mediated G-protein activation, can selectively stimulate Gs-independent β-arrestin signaling of βARs, a process known as β-arrestin-biased agonism.

Preliminary Study of Virtual-reality-guided Meditation for Veterans with Stress and Chronic Pain.

Altern Ther Health Med 2021 Sep 24. Epub 2021 Sep 24.

Context: Studies have found evidence for meditation's positive effects on health and well-being, but the difficulty of learning and engaging in meditation practice has been identified as a major barrier. Virtual reality (VR) technology may facilitate meditation practice by immersing users in a distraction-free and calming virtual environment, although this theory has yet to be rigorously tested.

Objective: This study intended to examine the efficacy of VR-guided meditation in a population of US veterans as a tool to facilitate meditation and relaxation practice for reduction of stress and chronic pain as well as to elicit participants' feedback regarding their perceptions of VR-guided meditation.

Influence of the Amount of Fresh Specimen on the Isolation of Tumor Mesenchymal Stem-Like Cells from High-Grade Glioma.

Yonsei Med J 2021 Oct;62(10):936-942

Yonsei University College of Medicine, Seoul, Korea.

Purpose: A critical indicator of the overall survival of patients with high-grade glioma is the successful isolation of tumor mesenchymal stem-like cells (tMSLCs), which play important roles in glioma progression. However, attempts to isolate tMSLCs from surgical specimens have not always been successful, and the reasons for this remain unclear. Considering that the amount of surgical high-grade glioma specimens varies, we hypothesized that larger surgical specimens would be better for tMSLC isolation. Read More

Role of mass spectrometry in the study of interactions between amylin and metal ions.

Mass Spectrom Rev 2021 Sep 24. Epub 2021 Sep 24.

Department of Medicine, University of Padova, Padova, Italy.

Amylin (islet amyloid polypeptide [IAPP]) is a neuroendocrine hormone synthesized with insulin in the beta cells of pancreatic islets. The two hormones act in different ways: in fact insulin triggers glucose uptake in muscle and liver cells, removing glucose from the bloodstream and making it available for energy use and storage, while amylin regulates glucose homeostasis. Aside these positive physiological aspects, human amyloid polypeptide (hIAPP) readily forms amyloid in vitro. Read More
