Blood Drop

Often called a “Digital Age Leonardo da Vinci”, Alexander Tsiaras is a digital innovator, technologist and artist. You might know him from his work that showcases beautiful digital images of the human body, made using cutting edge imaging software along with artsy tweaks. Guided by a passion for the human form and insides, Tsiaras founded the TheVisualMD, an extensive online library that documents human anatomy and illness, as well as Anatomical Travelogue, a company specialized in creating digital works of art that faithfully show the workings of the human body. He also authored a number of well received books like From Conception to Birth: A Life Unfolds, The Architecture and Design of Man and Woman: The Marvel of the Human Body, Revealed, The InVision Guide to a Healthy Heart and The InVision Guide to Sexual Health.

Sabotaging flagella of bacteria to halt infections

Some bacteria have the ability to ‘swim’ in a controlled fashion through the use of appendages called flagella. Researchers think that disabling these flagella is a key step towards infection control.

Motile bacteria move through the function of flagella. These appendages rotate, which propels an organism forwards. This is a little like the propellers on a boat. Some bacteria have one flagellum, others have many, and some possess none at all. Some of the bacteria regarded as human pathogens have flagella. An example of a flagellate bacterium is the ulcer-causing Helicobacter pylori, which uses multiple flagella to propel itself through the mucus lining to reach the stomach epithelium. Some flagella also serve a function in environmental detection, sensing different conditions and signalling to a bacterium to move to or away from a given niche.

New finding: Biobank storage time affects blood test results

The amount of time a blood sample has been stored at a biobank may affect the test results as much as the blood sample provider’s age. These are the findings of a new study from Uppsala University, which was published in the scientific journal EBioMedicine. Until now, medical research has taken into account age, sex and health factors of the person providing the sample, but it turns out that storage time is just as important.

They analysed 380 different samples from 106 women between the ages of 29 and 73. To study the impact of storage time, only samples from 50-year-old women were used in order to isolate the time effect. 108 different proteins were analysed. In addition to how long a sample had been frozen, the researchers also looked at what year the sample was taken and the age of the patient when the sample was taken.

‘We suspected that we’d find an influence from storage time, but we thought it would be much less’, says Professor Ulf Gyllensten. ‘It has now been demonstrated that storage time can be a factor at least as important as the age of the individual at sampling.’

Blood from biobanks has been used in research aimed at producing new drugs and testing new treatment methods. The results of this study are important for future drug research, but it is not possible or necessary, to repeat all previous biobank analyses.

Scientists have finally figured out how cancer spreads through the bloodstream

In what could be a major step forward in our understanding of how cancer moves around the body, researchers have observed the spread of cancer cells from the initial tumour to the bloodstream.

The findings suggest that secondary growths called metastases 'punch' their way through the walls of small blood vessels by targeting a molecule known as Death Receptor 6 (no, really, that's what it's called). This then sets off a self-destruct process in the blood vessels, allowing the cancer to spread.

According to the team from Goethe University Frankfurt and the Max Planck Institute in Germany, disabling Death Receptor 6 (DR6) may effectively block the spread of cancerous cells - so long as there aren't alternative ways for the cancer to access the bloodstream.

Free sBook - Atlas of Clinical Hematology

This 6th edition of the atlas has integrated the 2001 WHO classification and made use of figures and descriptions to document recently described types of leukemia and lymphoma. The latter include leukemias of dendritic cells, rare lymphomas and persistent polyclonal B lymphocytosis, which takes a special place in the classification.
