Clin Chem Lab Med 2021 Jun 14. Epub 2021 Jun 14.

Haematology, Institute of Clinical Pathology and Medical Research (ICPMR), NSW Health Pathology, Westmead Hospital, Westmead, NSW, Australia.

Objectives: Thrombophilia testing is commonly performed within hemostasis laboratories, and the ACL TOP 50 family of instruments represent a new 'single platform' of hemostasis instrumentation. The study objective was to evaluate these instruments and manufacturer reagents for utility of congenital thrombophilia assays.

Methods: Comparative evaluations of various congenital thrombophilia assays (protein C [PC], protein S [PS], antithrombin [AT], activated protein C resistance [APCR]) using newly installed ACL TOPs 550 and 750 as well as comparative assessments with existing, predominantly STAGO, instrumentation and reagents.

SARS-CoV-2 in pregnancy and possible transfer of immunity: assessment of peripartal maternal and neonatal antibody levels and a longitudinal follow-up.

J Perinat Med 2021 Jun 11. Epub 2021 Jun 11.

University Department of Obstetrics and Gynecology at the Hospital St. Hedwig of the Order of St. John, University of Regensburg, Regensburg, Germany.

Objectives: In the current Severe Acute Respiratory Distress Coronavirus 2 (SARS-CoV-2) pandemic there is still great uncertainty about the effects of an infection in pregnancy especially regarding a possible fetal transmission of antibodies to SARS-CoV-2 and the longevity of this immunity.

Ethical challenges in management of critically ill pregnant patients with coronavirus disease 2019 (COVID-19).

J Perinat Med 2021 Jun 11. Epub 2021 Jun 11.

Department of Obstetrics and Gynecology, Lenox Hill Hospital - Zucker School of Medicine at Hofstra/Northwell, New York, NY, USA.

Despite the overwhelming number of coronavirus disease 2019 (COVID-19) cases worldwide, data regarding the optimal clinical guidance in pregnant patients is not uniform or well established. As a result, clinical decisions to optimize maternal and fetal benefit, particularly in patients with critical COVID-19 in the early preterm period, continue to be a challenge for obstetricians. There is often uncertainty in clinical judgment about fetal monitoring, timing of delivery, and mode of delivery because of the challenge in balancing maternal and fetal interests in reducing morbidity and mortality.

Pre-sleep cognitive arousal exacerbates sleep disturbance in chronic pain: an exploratory daily diary and actigraphy study.

Scand J Pain 2021 Jun 14. Epub 2021 Jun 14.

Department of Psychological Medicine, The University of Auckland, Auckland, New Zealand.

Objectives: Insomnia is commonly comorbid with chronic pain, and typically leads to worse outcomes. Two factors that could contribute to a cycle of pain and sleeplessness are pre-sleep cognitive arousal (repetitive thought processes) and low mood. This study aimed to examine how pain, sleep disturbance, mood, and pre-sleep cognitive arousal inter-relate, to determine whether low mood or pre-sleep cognitive arousal contribute to a vicious cycle of pain and insomnia.

Ann & Robert H. Lurie Children's Hospital of Chicago, Northwestern University Feinberg School of Medicine, Chicago, IL, USA.

After more than 1 year of the SARS-CoV-2 pandemic, a great deal of knowledge on how this virus affects pregnant women, the fetus and the newborn has accumulated. The gap between different guidelines how to handle newborn infants during this pandemic has been minimized, and the American Academy of Pediatrics (AAP)'s recommendations are now more in accordance with those of the World Health Organization (WHO). In this article we summarize present knowledge regarding transmission from mother to the fetus/newborn. Read More

The molecular mechanism underlying pathogenicity inhibition by sanguinarine in Magnaporthe oryzae.

Pest Manag Sci 2021 Jun 11. Epub 2021 Jun 11.

Fuzhou Institute of Oceanography, Minjiang University, Fuzhou, 350108, China.

Background: Sanguinarine (SAN) is a benzophenanthridine alkaloid that broadly targets a range of pathways in mammalian and fungal cells. In this study we set to explore the molecular mechanism how sanguinarine inhibits fungal development and pathogenicity of Magnaporthe oryzae with the hope that sanguinarine will bolster the development of anti-blast agents.

Results: We found that the fungus exhibited a significant reduction in the vegetative growth and hyphal melanization while the spores produced long germ tubes on the artificial hydrophobic surface characteristic of a defect in thigmotropic sensing when exposed to 4 μM, 8 μM and 0. Read More

Circulating MicroRNA Responses to Postprandial Lipemia with or without Prior Exercise.

Int J Sports Med 2021 Jun 11. Epub 2021 Jun 11.

Department of Kinesiology, University of Maryland School of Public Health, College Park, United States.

Repeated exposure to a high-fat meal triggers inflammation and oxidative stress, contributing to the onset of cardiometabolic diseases. Regular exercise prevents cardiometabolic diseases and a prior bout of acute endurance exercise can counteract the detrimental cardiovascular effects of a subsequent high-fat meal. Circulating microRNAs (ci-miRs) are potential mediators of these vascular effects through regulation of gene expression at the posttranscriptional level. Read More

Nanoparticle-based drug delivery systems with platinum drugs for overcoming cancer drug resistance.

J Mater Chem B 2021 Jun 12. Epub 2021 Jun 12.

Department of Orthopedics, The Second Xiangya Hospital, Central South University, Changsha, Hunan 410011, China.

Platinum drugs are commonly used in cancer therapy, but their therapeutic outcomes have been significantly compromised by the drug resistance of cancer cells. To this end, intensive efforts have been made to develop nanoparticle-based drug delivery systems for platinum drugs, due to their multifunctionality in delivering drugs, in modulating the tumor microenvironment, and in integrating additional genes, proteins, and small molecules to overcome chemoresistance in cancers. To facilitate the clinical application of these promising nanoparticle-based platinum drug delivery systems, this paper summarizes the common mechanisms for chemoresistance towards platinum drugs, the advantages of nanoparticles in drug delivery, and recent strategies of nanoparticle-based platinum drug delivery.

Analyst 2021 Jun 12. Epub 2021 Jun 12.

State Key Laboratory of Analytical Chemistry for Life Science, School of Chemistry and Chemical Engineering, Nanjing University, 210023, Nanjing, China.

Nanopore electrochemistry, as one of the promising tools for single molecule sensing, has proved its capability in DNA sequencing and protein analysis. To achieve a high resolution for obtaining molecular information, the nanopore electrochemical technique not only urgently requires an appropriate nanopore sensing interface with atomic resolution but also requires advanced instrumentation and its related data processing methods. In order to reveal the fundamental biological process and process the point-of-care diagnosis, it is necessary to use a nanopore sensing instrument with a high amperometric and temporal resolution as well as high throughput.

Inhibition of the Ras/ERK1/2 pathway contributes to the protective effect of ginsenoside Re against intimal hyperplasia.

Food Funct 2021 Jun 12. Epub 2021 Jun 12.

Department of Pharmacology, School of Basic Medical Sciences, Xi'an Jiaotong University, Xi'an, Shaanxi 710061, China.

Neointimal hyperplasia is the major cause of carotid stenosis after vascular injury, which restricts the long-term efficacy of endovascular treatment and endarterectomy in preventing stenosis. Ginsenoside Re (Re) is a major active ingredient of ginseng having multifaceted pharmacological effects on the cardiovascular system, and is a potential treatment for restenosis. In this study, we demonstrated that Re treatment significantly inhibited vascular injury-induced neointimal thickening, reduced the intimal area and intima/media (I/M) ratio, increased the lumen area, and inhibited pro-inflammatory cytokines.

PLoS One 2021 11;16(6):e0252647. Epub 2021 Jun 11.

Department of Marine Biology and Ecology, Rosenstiel School of Marine and Atmospheric Science, University of Miami, Miami, FL, United States of America.

Aging of the nervous system is typified by depressed metabolism, compromised proteostasis, and increased inflammation that results in cognitive impairment. Differential expression analysis is a popular technique for exploring the molecular underpinnings of neural aging, but technical drawbacks of the methodology often obscure larger expression patterns. Co-expression analysis offers a robust alternative that allows for identification of networks of genes and their putative central regulators. Read More
