Hepatocellular Carcinoma (HCC) is one of the most common cancers worldwide with largely unfavorable outcomes due to a lack of effective treatment options for patients in the later state of disease. The gold standard of care for HCC patients with intermediate to locally advanced tumors is transcatheter arterial chemoembolization (TACE), a procedure whereby the tumor is targeted both with local chemotherapy and restriction of local blood supply. TACE procedures are often not effective however, and a need exists to identify patients that will respond to TACE.

DNA or RNA-based diagnostic tests for infectious diseases are critical in modern medicine. The current gold standard for COVID-19 detection is testing SARS-CoV-2 viral RNA by quantitative reverse transcription Polymerase Chain Reaction (RT-qPCR). This method involves patient sample collection with a nasopharyngeal swab, storage of the swab in a universal transport medium during transport to testing site, RNA extraction, and analysis of the extracted RNA sample.

The pattern or latency connectome was hypothesized to change in physiological development and disease.  For example, in amyotrophic lateral sclerosis (ALS), large diameter axons are damaged selectively – while in autism, small-diameter axons may be over-expressed. These anatomical changes are expected to alter the latency connectome or pattern of delays of information transmission between different gray matter areas involved in salient brain networks. 

The use of tumor transcriptomics for precision oncology has made significant advances, mainly by identifying cancer driver genes or actionable mutations for treatment with targeted therapies.  However, this strategy misses out on broader genetic interactions that could reveal additional biologically testable biomarkers for therapy response prediction and inform the selection of more effective drugs for targeted treatment.

Traumatic brain injury (TBI) represents a major medical, social and economic concern worldwide due to significant mortality – especially among younger populations – and long-term disabilities. Various pathological brain lesions (e.g., intracerebral bleedings, necrotic-ischemic lesions, tissue avulsion) are produced by impacting mechanical forces. Among these, diffuse axonal injury (DAI) is one of the most significant brain lesions typically associated with trauma. However, DAI is not necessarily linked with TBI exposure. Therefore, the term “traumatic axonal injury (TAI)” is commonly used.

Primary mediastinal B-cell lymphoma (PMBCL) is an aggressive type of non-Hodgkin lymphoma that mostly occurs in people between the ages of 30-40. It accounts for 5-7% of all aggressive lymphomas. The diagnosis of PMBCL is challenging as the histological features of PMBCL overlap with diffuse large B-cell lymphoma (DLBCL), another most common type of non-Hodgkin lymphoma. Available evidence suggests that PMBCL responds much more favorably to the DA-EPOCH-R chemotherapy regimen than to the standard R-CHOP regimen used to treat DLBCL.

Molecular profiling with high throughput assays has gained utility in the management of select cancer patients and several gene expression-based assays are now marketed for improved prognostic accuracy for patients with cancer.

Current methods of labeling and synthesizing RNA do not allow for multiple labels or long RNA segments to be synthesized for large RNA on a milligram scale.

Researchers at the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) developed an MRI-method that is based on the acquisition of multiple pulsed field gradient (m-PFG) rather than single-pulsed field gradient (s-PFG) MRI sequences. In particular, double PFG (dPFG) MRI sequences offer higher sensitivity and greater robustness, as they are more sensitive to the effects of “restriction;” i.e., to water trapped within the axon’s intracellular space, and thus to the diameter of the axons.
