In eukaryotes, histone acetylation is a major modification on histone N-terminal tails that is tightly connected to transcriptional activation. HDA6 is a histone deacetylase involved in the transcriptional regulation of genes and transposable elements (TEs) in Arabidopsis thaliana. HDA6 has been shown to participate in several complexes in plants, including a conserved SIN3 complex. Here, we uncover a novel protein complex containing HDA6, several Harbinger transposon-derived proteins (HHP1, SANT1, SANT2, SANT3, and SANT4), and MBD domain-containing proteins (MBD1, MBD2, and MBD4). We show that mutations of all four SANT genes in the sant-null mutant cause increased expression of the flowering repressors FLC, MAF4, and MAF5, resulting in a late flowering phenotype. Transcriptome deep sequencing reveals that while the SANT proteins and HDA6 regulate the expression of largely overlapping sets of genes, TE silencing is unaffected in sant-null mutants. Our global histone H3 acetylation profiling shows that SANT proteins and HDA6 modulate gene expression through deacetylation. Collectively, our findings suggest that Harbinger transposon-derived SANT domain-containing proteins are required for histone deacetylation and flowering time control in plants.Epithelial-to-mesenchymal transition (EMT) describes the loss of epithelial traits and gain of mesenchymal traits by normal cells during development and by neoplastic cells during cancer metastasis. The long noncoding RNA HOTAIR triggers EMT, in part by serving as a scaffold for PRC2 and thus promoting repressive histone H3K27 methylation. In addition to PRC2, HOTAIR interacts with the LSD1 lysine demethylase, an epigenetic regulator of cell fate during development and differentiation, but little is known about the role of LSD1 in HOTAIR function during EMT. Here, we show that HOTAIR requires its LSD1-interacting domain, but not its PRC2-interacting domain, to promote the migration of epithelial cells. PTEN inhibitor This activity is suppressed by LSD1 overexpression. LSD1-HOTAIR interactions induce partial reprogramming of the epithelial transcriptome altering LSD1 distribution at promoter and enhancer regions. Thus, we uncover an unexpected role of HOTAIR in EMT as an LSD1 decommissioning factor, counteracting its activity in the control of epithelial identity.This systematic review examined the impact of exercise intervention programs on selected cardiometabolic health indicators in adults with overweight or obesity. Three electronic databases were explored for randomized controlled trials (RCTs) that included adults with overweight or obesity and provided exercise-training interventions. Effects on blood pressure, insulin resistance (homeostasis model of insulin resistance, HOMA-IR), and magnetic resonance measures of intrahepatic fat in exercise versus control groups were analyzed using random effects meta-analyses. Fifty-four articles matched inclusion criteria. Exercise training reduced systolic and diastolic blood pressure (mean difference, MD = -2.95 mmHg [95% CI -4.22, -1.68], p  less then  0.00001, I2 = 63% and MD = -1.93 mmHg [95% CI -2.73, -1.13], p  less then  0.00001, I2 = 54%, 60 and 58 study arms, respectively). Systolic and diastolic blood pressure decreased also when considering only subjects with hypertension. Exercise training significantly decreased HOMA-IR (standardized mean difference, SMD = -0.34 [-0.49, -0.18], p  less then  0.0001, I2  = 48%, 37 study arms), with higher effect size in subgroup of patients with type 2 diabetes (SMD = -0.50 [95% CI -0.83, -0.17], p = 0.003, I2  = 39%). Intrahepatic fat decreased significantly after exercise interventions (SMD = -0.59 [95% CI -0.78, -0.41], p  less then  0.00001, I2 = 0%), with a larger effect size after high-intensity interval training. In conclusion, exercise training is effective in improving cardiometabolic health in adults with overweight or obesity also when living with comorbitidies.
In 2018, the first device to use high-intensity focused electromagnetic (HIFEM) technology to non-invasively build muscle was brought to market. Even more recently, the first HIFEM and radiofrequency combination device designed to both build muscle and eliminate fat cells came into use (HIFEM+). In view of the increase in recently published original data pertaining to HIFEM, an advisory board recently convened to discuss the group's clinical experiences with this technology.

Communicate an advisory group's recommendations for the current use of HIFEM+technology for aesthetic indications.

An advisory board meeting to discuss challenges and opportunities for HIFEM devices in aesthetic medicine took place in November 2020, via remote conference. The expert advisory board consisted of a group of senior aesthetic physicians regularly treating patients with non-invasive body contouring devices. A narrative review of the literature and key recommendations from the meeting are presented herein.

To date, the combined results of several clinical studies (including over 500 patients and 30 investigators) support that patients treated with HIFEM+experience on average, 30% less fat, 25% more muscle, 19% reduction in abdominal separation and up to 5.9cm reduction in waist circumference. Moreover, HIFEM+induces a 30% increase in satellite cell content, which is similar to the 36% increase observed following twelve weeks of exercise.

The advisory board unanimously agreed on several messages related to HIFEM technology, including that the pairing of HIFEM and radiofrequency (HIFEM+) enables a higher intensity of muscle stimulation and lipolysis, compared to HIFEM alone.

Here, we report that turning on human CDX2 expression in the hematopoietic lineage of mice induces acute monoblastic leukemia, characterized by the decrease in erythroid and lymphoid cells at the benefit of immature monocytic and granulocytic cells. One of the highly stimulated genes in leukemic bone marrow cells was BMP and activin membrane-bound inhibitor (Bambi), an inhibitor of transforming growth factor-β (TGF-β) signaling. The CDX2 protein was shown to bind to and activate the transcription of the human BAMBI promoter. Moreover, in a leukemic cell line established from CDX2-expressing mice, reducing the levels of CDX2 or Bambi stimulated the TGF-β-dependent expression of Cd11b, a marker of monocyte maturation. Taken together, this work demonstrates the strong oncogenic potential of the homeobox gene CDX2 in the hematopoietic lineage, in contrast with its physiological tumor suppressor activity exerted in the gut. It also reveals, through BAMBI and TGF-β signaling, the involvement of CDX2 in the perturbation of the interactions between leukemia cells and their microenvironment.
To understand how emergency nurses develop resilience in the context of workplace violence.

This study employed grounded theory methodology. Thirty nurses from three hospital emergency departments in Taiwan were interviewed between August and December 2018.

Semistructured interviews were used to collect data. Interviews were audio-recorded and transcribed verbatim.

The process through which emergency nurses who had experienced workplace violence developed resilience took place in three stages the release of emotions after the assault; the interpretation of conflicting thoughts and actions; and the establishment of strategies to cope with workplace violence in the future. The core theme was the motivating role of professional commitment to emergency patient care.

The results of this study can inform the development of support systems to enhance the resilience of nurses experiencing workplace violence by alerting healthcare administrators and governing institutions to their needs.

Emergency nurses viewed professional growth and professional commitment as an invisible motivator in the development of resilience following an encounter with workplace violence.

Pubmed, Web of Science, PsychInfo, and SportDiscus were searched up to October 2019 for peer-reviewed papers assessing exercise training effects on psychosocial outcomes in adults with overweight/obesity. Thirty-six articles, 32 randomized controlled trials (RCTs), were included in this review. Most interventions were supervised (65%), ranging between 6 and 76 weeks (median = 12). Sixteen psychological outcomes were studied. Exercise induced positive changes in quality of life but did not reduce depression. link2 Large effect sizes were observed on quality of life's physical component, but exercise was also able to improve vitality and mental health. Most psychological outcomes (e.g., body image, anxiety, and perceived stress) are poorly studied, evidencing either conflicting or null exercise effects. Exercise self-efficacy and autonomous motivations were also consistently improved. link3 Exercise types and gender seem to moderate exercise psychological effects. Exercise training programs might lead to positive changes in some psychological outcomes, especially in quality of life, in adults with overweight and obesity, but more studies, with greater systematization in program characteristics, and longer follow-ups are still required to allow more solid conclusions.
Wheat is a valuable food source that is exposed to many diseases that reduce its quantity and quality. One of the most important diseases affecting wheat is take-all, caused by Gaeumannomyces graminis var. tritici. The application of bacterial inoculants into the soil can increase plant nutrient absorption and enhance the efficiency of probiotic bacteria. For increased beneficial bacteria efficiency, the encapsulation technique has been used in agriculture.

The results of Fourier transform infrared (FTIR) and X-ray diffraction analysis (XRD) indicated that the prepared formulation is a mixture of gellan and chitosan. Using SEM, the spherical structure of the microcapsules was confirmed. It was observed that the increase in bacterial release was gradual, and the highest amount of bacteria was released (10
 CFU mL
) on the 50th day. Greenhouse experiments showed that plants treated with S. fulvissimus Uts22 microcapsules had the highest efficiency with 90% disease control. Moreover, the highest fresh and dry weights of roots and shoots were observed in this treatment.

In this study, a new type of formulation aiming at controlling wheat take-all disease was developed through bacterial and nanoparticles loaded chitosan- gellan gum microcapsules with spray drying method. This formulation has many advantages, such as a large surface area and high internal porosity and increased water-holding capacity, while it also provides a proper habitat for bacteria to increase colonization rates and offers protection of the soil.
