Quantification of urinary albumin in clinical samples using smartphone enabled LFA reader incorporating automated segmentation.

Smartphone-assisted urine analyzers estimate the urinary albumin by quantifying color changes at sensor pad of test strips. These strips yield color variations due to the total protein present in the sample, making it difficult to relate to color changes due to specific analyte. We have addressed it using a Lateral Flow Assay (LFA) device for automatic detection and quantification of urinary albumin.

Posttransplant Outcomes in Older Patients With Hepatocellular Carcinoma Are Driven by Non-Hepatocellular Carcinoma Factors.

The incidence of hepatocellular carcinoma (HCC) is growing in the United States, especially among the elderly. Older patients are increasingly receiving transplants as a result of HCC, but the impact of advancing age on long-term posttransplant outcomes is not clear. To study this, we used data from the US Multicenter HCC Transplant Consortium of 4980 patients.

Impact of Bridging Locoregional Therapies for Hepatocellular Carcinoma on Post-transplant Clinical Outcome.

Long waiting times due to ongoing organ shortage have led to increased utilization of locoregional therapies (LRTs) to bridge patients with hepatocellular carcinoma (HCC) to liver transplantation (LT). We performed this study to evaluate the impact of LRTs on post-LT outcomes. We conducted a retrospective study of patients who were transplanted for HCC at Stanford University Hospital between 2008 and 2018 (n = 302).

Antigen-loaded monocyte administration induces potent therapeutic antitumor T cell responses.

Efficacy of dendritic cell (DC) cancer vaccines is classically thought to depend on their antigen-presenting cell (APC) activity. Studies show, however, that DC vaccine priming of cytotoxic T lymphocytes (CTLs) requires the activity of endogenous DCs, suggesting that exogenous DCs stimulate antitumor immunity by transferring antigens (Ags) to endogenous DCs. Such Ag transfer functions are most commonly ascribed to monocytes, implying that undifferentiated monocytes would function equally well as a vaccine modality and need not be differentiated to DCs to be effective.

Toward Elimination of Hepatitis C Infection: How Best to Address Gaps in the Cascade of Care?

Because of the changing demographics of hepatitis C, screening for viral hepatitis should be done routinely in all pregnant woman. This process should include linkage to care. The best elimination strategy would incorporate universal screening for hepatitis C in all individuals over the age of 18.

Heart-targeted overexpression of Nip3a in zebrafish embryos causes abnormal heart development and cardiac dysfunction.

We transiently expressed a proapoptotic protein, Nip3a, by a heart-specific BMP4 promoter in zebrafish embryos and generated two variants of embryos with abnormal heart phenotypes (A and B). Embryos with phenotype A heart defects showed hypoplastic or elongated ventricles, elongated or enlarged atriums with no normal cardiac looping resulting a significant longer SV-BA distance, and bradycardia at 48 h post-fertilization (hpf). Embryos with phenotype B heart defects showed an enlarged fluid-filled pericardium, severe hypoplasia, non-contracting ventricles, and elongated or enlarged slowly beating atriums with no normal looping.
