Strange, Rare and Peculiar Symptoms of COVID-19 Cases Managed by Practitioners of the Homeopathy Help Network.

BACKGROUND: More than 670 million people have been infected by COVID-19. This case series reports 8 of 55 cases in a broader study of COVID-positive clients who sought homeopathic care for symptoms. Existing studies of homeopathy and COVID-19 have sometimes failed to employ the underpinning theoretical framework of homeopathy-the genus epidemicus. Special focus has been placed on standout symptoms not often reported in conventional medical outlets, known among homeopaths as "strange, rare and peculiar" (SRP) symptoms. The Homeopathy Help Network (HHN) team of practitioners noted SRP symptoms across dozens of cases and studied how they shifted collectively as different variants of the virus emerged. METHODS: COVID-positive individuals self-selected for individualized care for their symptoms using homeopathy. They received tele-health consultations and individualized homeopathy interventions in an out-patient homeopathy clinical setting. Clients were seen by individual professional homeopathy practitioners and students under supervision working at the HHN in the United States. Cases for the series were hand-picked with the aim of being an average representation of the more than 4,000 COVID-positive cases seen by members of the HHN. Cases in the full compendium are grouped according to a predominant case feature: Multiple remedies, Posology, Time ill, Single remedy resolution, Hospitalization and, in this case series, SRP symptoms. RESULTS: SRP symptoms included: continually on the verge of unconsciousness; dark green stools; very low pulse alternating with tachycardia; sensation of strong or burning chemical smells; sensation of inhaling water through the nose; recurring electric shock sensations in head or extremities; yellow-green stools. CONCLUSION: Collective SRP symptoms from the pandemic provided the opportunity to study the hallmark features of COVID-19 in depth. The importance of these symptoms highlights the applicability of Hahnemannian principles and good case-taking practices.

The CD4(+) T cell methylome contributes to a distinct CD4(+) T cell transcriptional signature in Mycobacterium bovis-infected cattle.

We hypothesised that epigenetic regulation of CD4(+) T lymphocytes contributes to a shift toward a dysfunctional T cell phenotype which may impact on their ability to clear mycobacterial infection. Combined RNA-seq transcriptomic profiling and Reduced Representation Bisulfite Sequencing identified 193 significantly differentially expressed genes and 760 differentially methylated regions (DMRs), between CD4(+) T cells from M. bovis infected and healthy cattle. 196 DMRs were located within 10 kb of annotated genes, including GATA3 and RORC, both of which encode transcription factors that promote TH2 and TH17 T helper cell subsets respectively. Gene-specific DNA methylation and gene expression levels for the TNFRSF4 and Interferon-γ genes were significantly negatively correlated suggesting a regulatory relationship. Pathway analysis of DMRs identified enrichment of genes involved in the anti-proliferative TGF-ß signaling pathway and TGFB1 expression was significantly increased in peripheral blood leukocytes from TB-infected cattle. This first analysis of the bovine CD4(+) T cell methylome suggests that DNA methylation directly contributes to a distinct gene expression signature in CD4(+) T cells from cattle infected with M. bovis. Specific methylation changes proximal to key inflammatory gene loci may be critical to the emergence of a non-protective CD4(+) T cell response during mycobacterial infection in cattle.

Comparative epigenetics: relevance to the regulation of production and health traits in cattle.

With the development of genomic, transcriptomic and bioinformatic tools, recent advances in molecular technologies have significantly impacted bovine bioscience research and are revolutionising animal selection and breeding. Integration of epigenetic information represents yet another challenging molecular frontier. Epigenetics is the study of biochemical modifications to DNA and to histones, the proteins that provide stability to DNA. These epigenetic changes are induced by environmental stimuli; they alter gene expression and are potentially heritable. Epigenetics research holds the key to understanding how environmental factors contribute to phenotypic variation in traits of economic importance in cattle including development, nutrition, behaviour and health. In this review, we discuss the potential applications of epigenetics in bovine research, using breakthroughs in human and murine research to signpost the way.

Exploring genome wide bisulfite sequencing for DNA methylation analysis in livestock: a technical assessment.

Recent advances made in "omics" technologies are contributing to a revolution in livestock selection and breeding practices. Epigenetic mechanisms, including DNA methylation are important determinants for the control of gene expression in mammals. DNA methylation research will help our understanding of how environmental factors contribute to phenotypic variation of complex production and health traits. High-throughput sequencing is a vital tool for the comprehensive analysis of DNA methylation, and bisulfite-based strategies coupled with DNA sequencing allows for quantitative, site-specific methylation analysis at the genome level or genome wide. Reduced representation bisulfite sequencing (RRBS) and more recently whole genome bisulfite sequencing (WGBS) have proven to be effective techniques for studying DNA methylation in both humans and mice. Here we report the development of RRBS and WGBS for use in sheep, the first application of this technology in livestock species. Important technical issues associated with these methodologies including fragment size selection and sequence depth are examined and discussed.
