The Biggest Obstacle to the Integration of Acupuncture: The Meaning of Qi from the Ancients to Einstein.

Qi continues to be questionably translated in the West as the biblical idea of lifeforce. The true meaning of qi may be closer to the Western scientific definition of energy as the material basis of everything in the Universe. To illustrate this, parallels are drawn between the writings of ancient Chinese thinkers and Western definitions of energy, including the laws of thermodynamics underlying Western scientific thought and yin-yang theory underlying Chinese scientific thought. The focus is on the similarities in theories of material reality while acknowledging how differences in cultural mindset create distinct styles of description of the same ideas. The purpose in establishing a more accurate translation of qi, by removing Western projections, is to improve patient-practitioner communication and to remove obstacles to the acceptance of acupuncture and Traditional Chinese Medicine as a mainstream medical intervention in the West.

Gender equality in academic gastroenterology: a review of gastroenterology literature over four decades.

BACKGROUND: Historically males have dominated the physician ranks, although in recent years, there has been an increase in the proportion of female doctors to redress this imbalance. With such attention being paid to gender equality in society, this study aimed to characterise the changing prevalence of female authorship of peer-reviewed published research with in the field of gastroenterology. AIMS: In order to quantitatively assess the growth of female gastroenterologists, we decided to examine the changing face of gender equality within the field of academic gastroenterology from 1971 to 2010. METHODS: All research published in the January and July issues of Gastroenterology from 1971 to 2010 was reviewed. The gender of the first author and last author (considered the senior author) of each study was recorded. Research was subsequently categorised by type: basic science research, clinical trials, and epidemiologic research. Data was analysed in 5-year time periods. RESULTS: Author gender could be identified from a total of 865 abstracts from 80 journal issues. In total, there were 120 (13.8%) female first authors and 91 (10.5%) female senior authors. Female first authorship has tripled since 1995, from 11% (1991-1995) to 32% (2006-2010). Female senior authorship has also tripled since 2000, from 7% (1996-2000) to 24% (2006-2010). DISCUSSION: Results demonstrated that there has been a significant increase in the prevalence of female authorship of published research in Gastroenterology since 1995. The increasing prevalence of females within the field of academic gastroenterology can therefore be extrapolated to demonstrate the growing numbers of female gastroenterologists in the entire field including clinical and academic gastroenterology.

A Biophysical Model for Cardiovascular Effects of Acupuncture-Underlying Mechanisms Based on First Principles.

According to recent translations by medical professionals of the foundational texts of Chinese Medicine, the acupuncture channel system can be reconciled with the neurovasculature. From there, the underlying mechanisms of the effects of acupuncture can be drawn from established physiology and known physical laws. A large body of research has been carried out using cardiovascular markers to measure the effects of acupuncture. Three of these parameters are re-viewed and explored anew in detail. The focus is on changes in microcirculation, blood pressure, and heart rate variability. The physiological mechanisms accounting for the observed changes are proposed to be ascending vasodilatation, resetting of the baroreceptor reflex, and re-organization of heart beating patterns around intrinsically assigned attractor sets.

Altered Degranulation and pH of Neutrophil Phagosomes Impacts Antimicrobial Efficiency in Cystic Fibrosis.

Studies have endeavored to understand the cause for impaired antimicrobial killing by neutrophils of people with cystic fibrosis (PWCF). The aim of this study was to focus on the bacterial phagosome. Possible alterations in degranulation of cytoplasmic granules and changes in pH were assessed. Circulating neutrophils were purified from PWCF (n = 28), PWCF receiving ivacaftor therapy (n = 10), and healthy controls (n = 28). Degranulation was assessed by Western blot analysis and flow cytometry. The pH of phagosomes was determined by use of BCECF-AM-labelled Staphylococcus aureus or SNARF labelled Candida albicans. The antibacterial effect of all treatments tested was determined by colony forming units enumeration. Bacterial killing by CF and healthy control neutrophils were found to differ (p = 0.0006). By use of flow cytometry and subcellular fractionation the kinetics of intraphagosomal degranulation were found to be significantly altered in CF phagosomes, as demonstrated by increased primary granule CD63 (p = 0.0001) and myeloperoxidase (MPO) content (p = 0.03). In contrast, decreased secondary and tertiary granule CD66b (p = 0.002) and decreased hCAP-18 and MMP-9 (p = 0.02), were observed. After 8 min phagocytosis the pH in phagosomes of neutrophils of PWCF was significantly elevated (p = 0.0001), and the percentage of viable bacteria was significantly increased compared to HC (p = 0.002). Results demonstrate that the recorded alterations in phagosomal pH generate suboptimal conditions for MPO related peroxidase, and α-defensin and azurocidine enzymatic killing of Staphylococcus aureus and Pseudomonas aeruginosa. The pattern of dysregulated MPO degranulation (p = 0.02) and prolonged phagosomal alkalinization in CF neutrophils were normalized in vivo following treatment with the ion channel potentiator ivacaftor (p = 0.04). Our results confirm that alterations of circulating neutrophils from PWCF are corrected by CFTR modulator therapy, and raise a question related to possible delayed proton channel activity in CF.
