Muscle fibers are closely related to human diseases and livestock meat quality. However, the genetics basis of microRNAs (miRNAs) in regulating muscle fibers is not completely understood. In this study, we constructed the whole genome-wide miRNA expression profiles of porcine fast-twitch muscle [biceps femoris (Bf)] and slow-twitch muscle [soleus (Sol)], and identified hundreds of miRNAs, including four skeletal muscle-highly expressed miRNAs, ssc-miR-378, ssc-let-7f, ssc-miR-26a, and ssc-miR-27b-3p. Moreover, we identified 63 differentially expressed (DE) miRNAs between biceps femoris vs. soleus, which are the key candidate miRNAs regulating the skeletal muscle fiber types. In addition, we found that the expression of DE ssc-miR-499-5p was significantly correlated to the expression of Myoglobin (r = 0.6872, P less then 0.0001) and Myosin heavy chain 7 (MYH7; r = 0.5408, P = 0.0020), and pH45 min (r = 0.3806, P = 0.0380) and glucose content (r = -0.4382, P = 0.0154); while the expression of DE ssc-miR-499-3p was significantly correlated to the expression of Myoglobin (r = 0.5340, P = 0.0024) and pH45 min (r = 0.4857, P = 0.0065). Taken together, our data established a sound foundation for further studies on the regulatory mechanisms of miRNAs in skeletal muscle fiber conversion and meat quality traits in livestock, and could provide a genetic explanation of the role of miRNAs in human muscular diseases.Many people are worried about developing dementia, fearing the losses and burdens that accompany the condition. Dementia-specific advance directives are intended to address dementia's progressive effects, allowing individuals to express their treatment preferences for different stages of the condition. But enthusiasm for dementia-specific advance directives should be tempered by recognition of the legal, ethical, and practical issues they raise. Dementia-specific advance directives are a simplistic response to a complicated situation. Although they enable people to register their future care preferences, in many cases, those preferences will not, and should not, determine their later care.Two articles in the March-April 2021 issue of the Hastings Center Report consider alterations to traditional informed consent. In "The Consent Continuum A New Model of Consent, Assent, and Nondissent for Primary Care," Marc Tunzi and colleagues argue that, in primary care settings, patient consent should be understood as taking a range of forms depending on the procedure, the patient, and the patient-care context. Traditional informed consent is at the ceremonious end; for many things done in these settings, the authors assert, assent or even nondissent is fine. In the lead article, health policy scholars Stephanie Morain and Emily Largent consider another continuum for informed consent, this one occurring with pragmatic research, at the intersection of clinical care with research.Cultural historians and historians of medicine are a rarity in bioethics. Even those who write histories of bioethics are philosophers, sociologists, or theologians. Where have all the historians gone? If bioethics is to contribute to the urgent work of addressing social justice, structural racism, and health inequity, we bioethicists need to embrace history as a fully constituent part of our field. Historians can help us apprehend the ideas that shaped bioethics, and health policy more broadly, and discover the dissenting arguments that might inspire us now. Given our annus horribilis, history has become an instrumental necessity. It is only through the study of history that we can understand the past so as to reimagine how bioethics can influence health policy and work toward health equity.This is a response to the letter to the editor "Prioritizing the Prevention of Early Deaths during Covid-19," by Govind Persad.This letter responds to the article "The Social Risks of Science," by Jonathan Herington and Scott Tanona, published in the November-December 2020 issue of the Hastings Center Report.This letter responds to the essay "When Is Age Choosing Ageist Discrimination?," by Teneille R. Brown, Leslie P. BAY-985 mw Francis, and James Tabery, published in the January-February 2021 issue of the Hastings Center Report.Research that is integrated into ongoing clinical activities holds the potential to accelerate the generation of knowledge to improve the health of individuals and populations. Yet integrating research into clinical care presents difficult ethical and regulatory challenges, including how or whether to obtain informed consent. Multiple empirical studies have explored patients' and the public's attitudes toward approaches to consent for pragmatic research. Questions remain, however, about how to use the resulting empirical data in resolving normative and policy debates and what kind of data warrants the most consideration. We recommend prioritizing data about what people consider acceptable with respect to consent for pragmatic research and data about people's informed, rather than initial, preferences on this subject. In addition, we advise caution regarding the weight given to majority viewpoints and identify circumstances when empirical data can be overridden. We argue that empirical data bolster normative arguments that alterations of consent should be the default in pragmatic research; waivers are appropriate only when the pragmatic research would otherwise be impracticable and has sufficiently high social value.The practice around informed consent in clinical medicine is both inconsistent and inadequate. Indeed, in busy, contemporary health care settings, getting informed consent looks little like the formal process developed over the past sixty years and presented in medical textbooks, journal articles, and academic lectures. In this article, members of the Society of Teachers of Family Medicine (STFM) Collaborative on Ethics and Humanities review the conventional process of informed consent and its limitations, explore complementary and alternative approaches to doctor-patient interactions, and propose a new model of consent that integrates these approaches with each other and with clinical practice. The model assigns medical interventions to a consent continuum defined by the discrete categories of traditional informed consent, assent, and nondissent. Narrative descriptions and clinical exemplars are offered for each category. The authors invite colleagues from other disciplines and from the academic ethics community to provide feedback and commentary.The Covid-19 pandemic has revealed myriad social, economic, and health inequities that disproportionately burden populations that have been made medically or socially vulnerable. Inspired by state and local governments that declared racism a public health crisis or emergency, the Anti-Racism in Public Health Act of 2020 reflects a shifting paradigm in which racism is considered a social determinant of health. Indeed, health inequities fundamentally rooted in structural racism have been exacerbated by the Covid-19 pandemic, which calls for the integration of antiracist praxis to promote ethical public health research processes. This commentary describes ways in which antiracist praxis-which emphasizes empowerment of traditionally marginalized populations-offers strategies to explicitly address power imbalance, stigmatization, and other consequences of structural racism in public health research.Harrowing stories reported in the media describe Covid-19 ravaging through families. This essay reports professional experiences of this phenomenon, family clustering, as encountered during the pandemic's spread across Southern California. We identify three ethical challenges following from it Family clustering impedes shared decision-making by reducing available surrogate decision-makers for incapacitated patients, increases the emotional burdens of surrogate decision-makers, and exacerbates health disparities for and the suffering of people of color at increased likelihood of experiencing family clustering. We propose that, in response to these challenges, efforts in advance care planning be expanded, emotional support offered to surrogates and family members be increased, more robust state guidance be issued on ethical decision-making for unrepresented patients, ethics consultation be increased in the setting of conflict following from family clustering dynamics, and health care professionals pay more attention to systemic and personal racial biases and inequities that affect patient care and the surrogate experience.

Eosinophilic esophagitis (EoE) is a T-cell-mediated disease that is caused by specific foods and results in esophageal dysfunction. Existing allergy testing modalities are not helpful when attempting to identify EoE-causal foods necessitating empiric food elimination and recurrent endoscopy. The goal of this study was to identify and compare allergen-specific immune features that can be assayed in a minimally invasive manner to predict clinical food allergy in EoE.

We obtained blood samples from control subjects (n=17), subjects with clinical EoE milk allergy (n=17), and subjects with immunoglobulin E-mediated milk allergy (n=9). We measured total and milk-specific plasma immunoglobulin G (IgG)4 levels and peripheral memory CD4

T helper (T

) cell proliferation and cytokine production after stimulation with endotoxin-depleted milk proteins. Sensitivity and specificity for predicting clinical EoE milk allergy were calculated and compared between approaches.

Total and milk-specific IgG4 levels were notost accurately predicts clinical EoE milk allergy.Biochar application has recently gained increased attention to reclaim heavy metal degraded soils. In this context, the present study investigated the effects of biochar on the growth regulation and heavy metal accumulation in tomato grown on contaminated soils. A two-factorial design with factor A including three treatments with mine (contaminated soil) and garden soil in the following ratio viz., T1 = 12, T2 = 11, and T3 = 21, and garden soil only as control; whereas factor B consists of biochar amendments at three levels viz., B1 (3%), B2 (6%), and B3 (9%). Our results revealed significant negative effects of heavy metal-contaminated soil on plant growth, and besides resulted heavy metal accumulation in tomato fruit. Tomato plants showed maximum reduction of growth in T3 followed by T2, and lowest in T1, a similar pattern was found for accumulation of heavy metals in the fruit. However, the application of biochar reduced the bioavailability and accumulation of heavy metals in the tomato fruit, as well as improved plant growth in contaminated soils. Overall, among the three biochar treatments, B2 was determined as the optimum level for improved growth coupled with reduced heavy metal accumulation in the tomato fruit. Besides, biochar application decreased the daily intake of metals and human health risk index values, thus alleviating the health risk. Hence, the present study demonstrated a positive role of biochar in reclaiming heavy metal-contaminated soils and in increasing the plant growth.

This study aimed to assess the association between iron deficiency anaemia (IDA) and dental caries in early childhood.

A total of 40 children with proven IDA and another 40 healthy age and sex-matched children were enrolled in this cross-sectional study. Legal guardians were interviewed to collect data on oral hygiene measures and dietary habits. Anthropometric measurements were performed for all participants, and blood samples were collected to assess complete blood count and body iron status. Patients were confirmed to have IDA based on haemoglobin level (Hb), red blood cells indices and body iron status. Caries experience was determined based on the number of decayed, missing and filled primary teeth using dmft index.

A statistically significant negative correlation between dmft index scores and haemoglobin level (r=-0.454, P<0.001) and mean corpuscular haemoglobin (MCH) level (r=-0.380, P=0.001) was detected, and in accordance there was a positive statistically significant correlation between caries experience and the presence of anaemia (r=-0.
