Cytovale®, a medical diagnostics company focused on providing rapid and insightful tools to improve early detection of fast-moving and immune-mediated diseases, will reveal its 510(k) pending Cytovale system and 10-minute IntelliSep® sepsis risk stratification test at the American Association for Clinical Chemistry (AACC) annual meeting, where new data featuring the test will also be shared. The instrument can be seen in the Cytovale booth, no. 5045, in the exhibit hall during Clinical Lab Expo hours. The IntelliSep test was recently named an AACC Disruptive Technology Award Semifinalist and is also being featured in the Disruptive Tech area of the exhibit hall during the meeting.
Researchers at Mayo Clinic's Center for Individualized Medicine have discovered key human genomic signatures that could help explain why COVID-19 is severe in some people and mild in others. After analyzing volumes of diverse worldwide DNA sequence data, the scientists identified mutations in two human proteins that might sway the course of SARS-CoV-2 — the virus responsible for COVID-19.
The Omicron variant of the SARS-CoV-2 virus was first detected in South Africa in November 2021. The high level of infectiousness of the virus and its ability to quickly spawn additional variants has also been observed in Germany: Since January 2022 the Omicron variant BA.1 has dominated here, followed in subsequent months by the variant BA.2.
For patients with lymphoma, multiple myeloma, or certain types of leukemia, treatment with chimeric antigen receptor T cells (CAR T cells) is sometimes the last chance of overcoming the cancer.

Patients infected with SARS-CoV-2 develop protective immune responses, mediated by virus-specific T cells and antibodies, shortly after the infection.
Cancer cells produce small amounts of their own form of collagen, creating a unique extracellular matrix that affects the tumor microbiome and protects against immune responses, according to a new study by researchers at The University of Texas MD Anderson Cancer Center. This abnormal collagen structure is fundamentally different from normal collagen made in the human body, providing a highly specific target for therapeutic strategies.
Protection against severe COVID-19 by two doses of Pfizer-BioNTech and AstraZeneca COVID-19 vaccines remained high up to six months after second doses, finds new research which analysed NHS health record data on over seven million adults. Reassuringly, the University of Bristol-led study published in The BMJ today [July 20], found protection in older adults aged over 65 years, and in clinically vulnerable adults.
Paramyxoviruses have the potential to trigger a devastating pandemic. This family of viruses includes measles, Nipah virus, mumps, Newcastle disease and canine distemper. An international team of collaborators has published the first-ever look at a key stage in the life cycles of measles and Nipah viruses. It reveals how future therapies might stop these viruses in their tracks.
