A novel peptide has been developed to selectively detect and neutralize an early molecular trigger of Alzheimer's disease. The technology allows for the detection of the disease at all stages, including presymptomatic cases, with high sensitivity and specificity.
SourceBioscribe·JournalProceedings of the National Academy of Sciences·TypeExperimental study·DateDec 5, 2022 Researchers have identified unique metabolic signatures, called metabotypes, in over 50% of children with autism spectrum disorder. These biomarkers, detected through metabolomics tests, show promise in detecting early risk and potentially personalized therapies for ASD.
A new cell-based test developed by Stemina Biomarker Discovery accurately predicts the potential of drugs and chemicals to cause birth defects in humans. The devTOXqP test uses human embryonic stem cells to detect developmental toxicity with an accuracy of 82%, highlighting a promising alternative to animal testing.
The study demonstrated the potential of body-on-a-chip systems to transform the drug discovery process by accurately predicting cardiotoxic mechanisms and replicating in vivo results. The findings support the use of in vitro models to evaluate temporal pharmacokinetic/pharmacodynamic relationships.
A human-on-a-chip model developed by Hesperos, Inc. realistically replicates the responses of cancer treatments, enabling more accurate and efficient preclinical testing. The model demonstrated efficacy and toxicity of anticancer drugs on various cell lines, informing treatment decisions for individual patients.
Researchers have developed a human-on-a-chip model that can mimic the effects of chronic drug exposure, overcoming limitations of previous organ-on-a-chip systems. This breakthrough technology allows for realistic replication of system responses to compounds, enabling more accurate prediction of toxicity and efficacy.
Scientists have assembled a comprehensive map of Aedes aegypti mosquito DNA using long-read sequencing technology, providing a much more complete and accurate picture of gene elements. The new genome has already revealed critical clues into how the insects sense chemical cues and has identified 49 new genes involved in immune responses.
A saliva-based RNA panel and algorithm can differentiate children with autism from non-autistic peers with 85% accuracy. This test could improve early diagnosis, enabling earlier intensive behavioral therapy to improve symptoms.
A novel saliva-based panel is being developed to aid clinicians in the early diagnosis of autism spectrum disorder based on changes in oral microbial communities. The study found altered microbial gene expression patterns associated with energy processing and lysine degradation, indicating potential biomarkers for ASD.
The Wellcome Sanger Institute has sequenced the genomes of over 3,000 bacteria, including some of the world's most dangerous pathogens. This collection will help researchers better understand antibiotic resistance and develop new diagnostic tests, vaccines, or treatments for deadly diseases such as tuberculosis, gonorrhoea, and cholera.
A preclinical study demonstrates the effectiveness of PRO 140, a humanized anti-CCR5 monoclonal antibody, in preventing graft-versus-host disease (GvHD) in bone marrow stem cell transplantation. The study shows that PRO 140 successfully blocked GvHD development without affecting hematopoietic cell engraftment.
A Phase 2 study of a novel colonoscopy prep found it to be at least as effective and safe as existing products, while offering higher levels of patient satisfaction and preference. The investigational treatment allows patients to eat solid food bars and drink palatable beverages, leading to nearly four times more recommendations.
Scientists have assembled the gorilla genome using PacBio's long-read SMRT sequencing, achieving a 150-fold improvement over previous assemblies. The new assembly recovers nearly all missing sequence and provides additional euchromatic sequence, enabling researchers to study biological mechanisms and traits.
Researchers at Osel have engineered Lactobacillus jensenii to stably express broadly neutralizing antibody fragments against the HIV-1 virus, offering a cost-effective and long-lasting new barrier to HIV-1 transmission. The engineered bacteria reduced vaginal HIV transmission in a primate animal model by over 63%.
A new single-cell gene expression technology allows for the study of large numbers of genes in tens of thousands to hundreds of thousands of cells at once. The technology uses cell- and molecule-specific barcodes to enable the analysis of gene activity with absolute quantification.
The Cancer Genome Atlas study identifies four main breast cancer subtypes defined by PAM50, with diverse genetic and epigenetic alterations converging into these phenotypes. The study's findings advance understanding of breast cancer biology and support the use of PAM50 as a gold standard for categorizing breast cancer by subtype.
An international team of scientists used single molecule, real-time DNA sequencing technology to analyze the pathogenicity and evolutionary origins of the highly virulent German E. coli outbreak strain. The results provide the most detailed genetic profile to date, highlighting the importance of DNA sequencing in understanding how bact...
The study provides the first whole genome sequence analysis of the Haitian Vibrio cholerae outbreak strain, confirming a South Asian lineage. This understanding has important public health policy implications for preventing future cholera outbreaks.
