This study identifies the missing link between Lewy bodies and the type of damage that's been observed in neurons affected by Parkinson's. Parkinson's is a disorder of the mitochondria, and we discovered how Lewy bodies are releasing a partial break-down product that has a high tropism for the mitochondria and destroys their ability to produce energy." Lewy bodies were described a century ago, but it was not until 1997 that scientists discovered they were made of clumps of a misfolded protein called α-synuclein. When it's not misfolded, α-synuclein is believed to carry out functions related to the transmission of signals between neurons. Researchers looked at cell cultures of neurons that were induced to accumulate fibrils made of misfolded α-synuclein, mimicking Lewy bodies in patients with Parkinson's. They discovered that when α-synuclein fibrils are broken down, it often creates a smaller protein clump, which they named pα-syn* (pronounced "P-alpha-syn-star"). It turns out that the result of that partial degradation, pα-syn*, is toxic. Researchers made this discovery by labeling the pα-syn* with an antibody so they could follow it throughout the cell after it was created. They observed that pα-syn* traveled and attached itself to the mitochondria. Further investigation revealed that once the pα-syn* attached, the mitochondria started to break down. These fragmented mitochondria lose their ...

Publication date: May 2020Source: Clinica Chimica Acta, Volume 504Author(s): Damian Jacenik, Jakub FichnaAbstractChemerin is a multifunctional protein involved among others in adipogenesis, angiogenesis and lipid as well as glucose metabolism. Chemerin is an essential factor in promotion of chemotaxis of numerous immune cell types and plays an important role in several pathophysiologic conditions. Chemerin receptors are present on monocytes/macrophages, T cells, natural killer and dendritic cells as well as neutrophils. However, the role of chemerin and chemerin receptors in immune response and gastrointestinal diseases is...

ConclusionsPatients with CMS were more likely to present with increased comorbidities. Patients with CMS undergoing CABG were at risk for worse short ‐term secondary postoperative outcomes and reduced long‐term survival. The data supports the need for further investigation for risk reduction surrounding operative revascularization.

AbstractCoarctation is rare in patients over 50 years of age; however, if present, it can be associated with complex intracardiac pathologies and represent a formidable surgical challenge. Herein, we report a single ‐stage approach for surgical repair of coarctation associated with aortic, mitral, and tricuspid valve pathology using an ascending‐to‐descending aortic bypass with posterior pericardial access.

The levels of HMF and F in Chinese vinegars from different regions were analyzed and discussed. F ranged from 4.35 to 313.95 mg/L, with an average value of 136.71 mg/L, while the mean level of HMF was 103.69 mg/L (26.83–455.13 mg/L). A significant positive corr...

ByardAbstractIn previous years individuals with tattoos were thought to have a higher rate of mental illness and risk taking behaviour. With the widespread adoption of tattoos in Western countries in recent years this negative association has been questioned. An issue which arises, however, is that “tattooing” is a heterogeneous activity that covers a wide spectrum of designs and motivations. To examine the characteristics of individuals presenting to medicolegal autopsy with “expletive tat...
