New bioprinting process uses ultrashort peptides to print hydrogel scaffolds
A new automated process prints a peptide-based hydrogel scaffold containing uniformly distributed cells. The scaffolds hold their shapes well and successfully facilitate cell growth that lasts for weeks. Bioprinting 3D printing that incorporates living cells has the potential to revolutionize tissue engineering and regenerative medicine. Scientists have experimented with natural and synthetic bioinks to print out scaffolds that hold cells in place as they grow and form a tissue with a specific shape. But there are challenges with cell survival.
Natural bioinks, such as gelatin and collagen, need to be treated with chemicals or ultraviolet light to hold their shape, which affects the cell viability. The synthetic polymer hydrogels tested to date also require the use of harsh chemicals and conditions that threaten cell survival.

In some cancers, including leukemia in children and adolescents, obesity can negatively affect survival outcomes. Obese young people with leukemia are 50% more likely to relapse after treatment than their lean counterparts.
Study: One in six men with advanced prostate cancer experiences reduced sense of smell and taste
One in six men being treated for advanced prostate cancer experiences a reduced sense of smell and taste, a symptom that could cause increased anxiety among patients because it is also a side effect of COVID-19, according to Tulane researchers.
A study published in the journal Supportive Care in Cancer says a reduced sense of smell and taste among some prostate cancer patients is largely associated with poor appetite and weight loss.
Although the data collection for the study predated the COVID-19 pandemic, the results pose important implications for cancer patients undergoing hormone therapy, chemotherapy and/or bone antiresorptive during the coronavirus crisis.
