Dynamic visualization of DNA methylation in cell cycle genes during iPSC cardiac differentiation.

Background: Existing analyses with conventional assays have generated significant insights into static states of DNA methylation but were unable to visualize the dynamics of epigenetic regulation.

Materials & Results: We utilized a genomic DNA methylation reporter (GMR) system carrying Snrpn minimal promoter and CpG regions of (Cyclin-dependent kinase 1) or (SRY-Box Transcription Factor 2). Mouse Sox2 GMR iPSCs rapidly lost fluorescent reporter signal upon the induction of cardiac differentiation.

Using the Kirkpatrick Model to Evaluate the Effect of a Primary Trauma Care Course on Health Care Workers' Knowledge, Attitude, and Practice in Two Vietnamese Local Hospitals: Prospective Intervention Study.

Background: The Primary Trauma Care (PTC) course was originally developed to instruct health care workers in the management of patients with severe injuries in low- and middle-income countries (LMICs) with limited medical resources. PTC has now been taught for more than 25 years. Many studies have demonstrated that the 2-day PTC workshop is useful and informative to frontline health staff and has helped improve knowledge and confidence in trauma management; however, there is little evidence of the effect of the course on changes in clinical practice.

Due to the latent infection of and its heterogenous species complex, controlling the disease becomes difficult.

COVID-19 in Vietnam and Its Impact on Road Trauma: Retrospective Study Based on National Data.

Background: Despite significant improvement in the last decade, road trauma remains a substantial contributor to deaths in Vietnam. The COVID-19 pandemic necessitated public health measures that had an unforeseen benefit on road trauma in high-income countries. We investigate if this reduction was also seen in a low- to middle-income country like Vietnam.

Plant associated protists-Untapped promising candidates for agrifood tools.

The importance of host-associated microorganisms and their biotic interactions for plant health and performance has been increasingly acknowledged. Protists, main predators and regulators of bacteria and fungi, are abundant and ubiquitous eukaryotes in terrestrial ecosystems. Protists are considered to benefit plant health and performance, but the community structure and functions of plant-associated protists remain surprisingly underexplored.

Trauma Care Training in Vietnam: Narrative Scoping Review.

Objective: This study aimed to establish if medical training in the developing country of Vietnam has adapted to the new disease pattern of road trauma emerging in its economy.

Livestock manure spiked with the antibiotic tylosin significantly altered soil protist functional groups.

With the increasing global antibiotic uses in livestock husbandry, animal manures upon land application pose potential threats to the environments and soil microbiome. Nevertheless, effects of manures and antibiotic-administered manures on soil protists, an integral component of soil food web and primary regulators of bacteria, remain unknown. Here, we assessed impacts of cattle and poultry manures with or without an antibiotic tylosin on soil protists and their functional groups in a 130-day microcosm incubation.

Precipitation increases the abundance of fungal plant pathogens in Eucalyptus phyllosphere.

Understanding the current and future distributions of plant pathogens is critical to predict the plant performance and related economic benefits in the changing environment. Yet, little is known about the roles of environmental drivers in shaping the profiles of fungal plant pathogens in phyllosphere, an important habitat of microbiomes on Earth. Here, using a large-scale investigation of Eucalyptus phyllospheric microbiomes in Australia and the multiple linear regression model, we show that precipitation is the most important predictor of fungal taxonomic diversity and abundance.

Termite mound formation reduces the abundance and diversity of soil resistomes.

Termites are pivotal ecosystem engineers in tropical and subtropical habitats, where they construct massive nests ('mounds') that substantially modify soil properties and promote nutrient cycling. Yet, little is known about the roles of termite nesting activity in regulating the spread of antimicrobial resistance (AMR), one of the major Global Health challenges. Here, we conducted a large-scale (> 1500 km) investigation in northern Australia and found distinct resistome profiles in termite mounds and bulk soils.

Termite mounds reduce soil microbial diversity by filtering rare microbial taxa.

Termites are ubiquitous insects in tropical and subtropical habitats, and some of them construct massive nests ('mounds'), which substantially promote substrate heterogeneity by altering soil properties. Yet, the role of termite nesting process in regulating the distribution and diversity of soil microbial communities remains poorly understood, which introduces uncertainty in predictions of ecosystem functions of termite mounds in a changing environment. Here, by using amplicon sequencing, we conducted a survey of 134 termite mounds across >1500 km in northern Australia and found that termite mounds significantly differed from bulk soils in the microbial diversity and community compositions.

Localized skin inflammation during cutaneous leishmaniasis drives a chronic, systemic IFN-γ signature.

Cutaneous leishmaniasis is a localized infection controlled by CD4+ T cells that produce IFN-γ within lesions. Phagocytic cells recruited to lesions, such as monocytes, are then exposed to IFN-γ which triggers their ability to kill the intracellular parasites. Consistent with this, transcriptional analysis of patient lesions identified an interferon stimulated gene (ISG) signature.

Competition for Active TGFβ Cytokine Allows for Selective Retention of Antigen-Specific Tissue- Resident Memory T Cells in the Epidermal Niche.

Following antigen-driven expansion in lymph node, transforming growth factor-β (TGFβ) is required for differentiation of skin-recruited CD8 T cell effectors into epidermal resident memory T (Trm) cells and their epidermal persistence. We found that the source of TGFβ -supporting Trm cells was autocrine. In addition, antigen-specific Trm cells that encountered cognate antigen in the skin, and bystander Trm cells that did not, both displayed long-term persistence in the epidermis under steady-state conditions.

Biodegradation of dioxins by Burkholderia cenocepacia strain 869T2: Role of 2-haloacid dehalogenase.

Dioxin compounds are persistent carcinogenic byproducts of anthropogenic activities such as waste combustion and other industrial activities. The ubiquitous distribution of dioxins is global concerns these days. Among of recent techniques, bioremediation, an eco-friendly and cost-effective technology, uses bacteria or fungi to detoxify in dioxins; however, not many bacteria can degrade the most toxic dioxin congener 2,3,7,8-tetrachlorinated dibenzo-p-dioxin (TCDD).

Granzyme B Inhibition by Tofacitinib Blocks the Pathology Induced by CD8 T Cells in Cutaneous Leishmaniasis.

In cutaneous leishmaniasis, the immune response is not only protective but also mediates immunopathology. We previously found that cytolytic CD8 T cells promote inflammatory responses that are difficult to treat with conventional therapies that target the parasite. Therefore, we hypothesized that inhibiting CD8 T-cell cytotoxicity would reduce disease severity in patients.

Oxytetracycline and Ciprofloxacin Exposure Altered the Composition of Protistan Consumers in an Agricultural Soil.

Protists, an integral component of soil microbiome, are one of the main predators of bacteria. Bacteria can produce toxic secondary metabolites, e.g.

Microbial regulation of natural antibiotic resistance: Understanding the protist-bacteria interactions for evolution of soil resistome.

The emergence, evolution and spread of antibiotic resistance genes (ARGs) in the environment represent a global threat to human health. Our knowledge of antibiotic resistance in human-impacted ecosystems is rapidly growing with antibiotic use, organic fertilization and wastewater irrigation identified as key selection pressures. However, the importance of biological interactions, especially predation and competition, as a potential driver of antibiotic resistance in the natural environment with limited anthropogenic disturbance remains largely overlooked.

Variable gene expression and parasite load predict treatment outcome in cutaneous leishmaniasis.

Patients infected with develop chronic lesions that often fail to respond to treatment with antiparasite drugs. To determine whether genes whose expression is highly variable in lesions between patients might influence disease outcome, we obtained biopsies of lesions from patients before treatment with pentavalent antimony and performed transcriptomic profiling on these clinical samples. We identified genes that were highly variably expressed between patients, and the variable expression of these genes correlated with treatment outcome.

Objective: The essential prerequisite for focused parathyroidectomy in patients with primary hyperparathyroidism (pHPT) is proper localization of all autonomic tissue. Sensitivity of conventional imaging modalities (ultrasound, Tc-sestamibi scintigraphy/SPECT/CT) is influenced by different factors (i.e.

Genetic background defines the regulation of postnatal cardiac growth by 17β-estradiol through a β-catenin mechanism.

Estrogen regulates several biological processes in health and disease. Specifically, estrogen exerts antihypertrophic effects in the diseased heart. However, its role in the healthy heart remains elusive.

Human classical monocytes control the intracellular stage of Leishmania braziliensis by reactive oxygen species.

Leishmania braziliensis are intracellular parasites that cause unique clinical forms of cutaneous leishmaniasis. Previous studies with other leishmania species demonstrated that reactive oxygen species (ROS) control promastigotes, the infective stage of the parasite, but not the amastigote form that exists in the mammalian host. Here we show that ROS inhibits growth of L.

Estrogen modulates cardiac growth through an estrogen receptor α-dependent mechanism in healthy ovariectomized mice.

The modulation of cardiac growth by estrogen in healthy mice is not completely understood. The aim was to investigate the effects of estrogen on cardiac growth in healthy mice lacking either estrogen receptor (ER) α or β. Wild-type (WT), ERα knockout (ERKO) and ERβ knockout (BERKO) 2-month-old mice were ovariectomized and randomly assigned to groups receiving an estradiol (E2)-containing or soy-free (control, CON) diet (n=5-7/group).

Dose-dependent effects of a genistein-enriched diet in the heart of ovariectomized mice.

The isoflavone genistein is used as a pharmacological compound and as a food supplement. The duration and the level of exposure of humans to genistein are considerable. However, the magnitude of genistein-supplemented dietary interventions necessary to induce any changes in the heart has not been studied so far.
