Fight Aging! Newsletter, September 10th 2018

In conclusion, HSC ageing is characterised by reduced self-renewal, myeloid and platelet HSC skewing, and expanded clonal haematopoiesis that is considered a preleukaemic state. The underlying molecular mechanisms seem to be related to increased oxidative stress due to ROS accumulation and DNA damage, which are influenced by both cell- and cell non-autonomous mechanisms such as prolonged exposure to infections, inflammageing, immunosenescence, and age-related changes in the HSC niche. Thus, HSC ageing seems to be multifactorial and we are only beginning to connect all the dots. The Price of Progress or the Waste of Regulation? https://www.fightaging.org/archives/2018/09/the-price-of-progress-or-the-waste-of-regulation/ The average cost of delivering a new therapy from laboratory to clinic is increasing at a fast pace, more than doubling since the turn of the century according to some studies, to stand at 2.5 billion or more. This is not driven by the work of research and development becoming more expensive: if anything, the price of the tools of biotechnology is in free fall, even as capacity increases by orders of magnitude. Biotechnology has gone through, and is still going through, its own echoed version of the computing revolution of recent decades. A mix of advances in computational power and materials science means that a graduate student of today requires six months of lab time and a few tens of thousands in funding to accomplish what would have tak...

Publication date: March–April 2020Source: Journal of Applied Developmental Psychology, Volume 67Author(s): Claudine FoxAbstractThis paper reports a study that adopted age-appropriate terminology to investigate 6–11-year-old children's attitudes towards mental illness (N = 120). The study utilized a semi-structured interview technique and card selection tasks to assess the children's attitudes to individuals diagnosed with different mental illnesses (anorexia nervosa, depression and dementia). Their attitudes were measured in terms of social distance, social functioning, emotional response and trait at...

Dave OomahAbstractCranberry (Vaccinium macrocarpon) fruits are known for their high polyphenolics content making them a rich source of antioxidants. These polyphenolics have been reported to promote human health and are gaining attention for their antimicrobial activities against foodborne pathogens. We investigated the antimicrobial activity of an ethanolic extract #(FC111-1) prepared from cranberry pomace against Listeria spp. Many polyphenolics were identified ...

Therefore, inhibition of protein glycation could be a key strategy to prevent these diabetic abnormalities. Evaluation of phenolic compositions and their antiglycation activity revealed that p-coumaric and chlorogenic acids were major phenolic acids in barnyard millet. These phenolics exhibited multiple antioxidant activities in various mechanisms and protected the oxidative DNA damage and hydroxyl radical-...

The aim of this study was to identify biomarkers of B. cinerea infection in sweet wines with a focus on laccases which are exocellular oxidase enzymes produced by this fungus during fruit contamination. Total proteins from six commercial sweet wines, including three naturally botrytized wines and three non-botrytized wines were analysed by LC-QTOF-MS. Five laccases, namely laccase-1...

We examined sexual dimorphism and variability of craniomandibular morphology in the Japanese giant flying squirrel (Petaurista leucogenys) using different statistical analyses. Among 31 measurements using 33 adult skulls (19 males and 14 females), females showed slightly larger mean size for all traits. Univariate analysis revealed that females were significantly larger than males for the greatest length of skull, zygomatic breadth, and mandibular length. Discriminant functions indicated well distinctiveness between the sexes. Moreover, six additional mandibular measurements were taken for estimating the mechanical advanta...

This study assessed whether the endemic status of this disease was stable or instable, which is important for disease control efforts. For this aim, 4115 sheep blood samples were collected from 81 cities in the seven geographical regions of Turkey. The diagnosis of Babesia ovis was made using microscopic and serological techniques. Thin blood smears were prepared from anticoagulated venous blood. Serum samples were screened for specific antibodies using an enzyme-linked immunosorbent assay (ELISA) and indirect fluorescent antibody test (IFAT). Recombinant Babesia ovis secreted antigen 1 (rBoSA1) was used in the ELISA. The ...
