This study aimed to investigate the effects of laminarin (LA) and ferulic acid (FA) on the gelatinization, rheological properties, freeze-thaw stability, and digestibility of cassava starch (CS). The results indicated that LA increased the peak viscosity, trough viscosity, final viscosity, storage modulus, and loss modulus of CS, while decreasing the breakdown viscosity. Conversely, FA exerted opposite effects.

Hypothesis: Monodisperse phospholipid-coated microbubbles, with a size and resonance frequency tuned to the ultrasound driving frequency, have strong potential to enhance sensitivity, efficiency, and control in emerging diagnostic and therapeutic applications involving bubbles and ultrasound. A key requirement is that they retain their gas volume and shell material during physiologic pressure changes and withstand the overpressure during intravenous injection. The shell typically comprises a mixture of a phospholipid (e.

In this work, an integrated microfluidic microwave array sensor is proposed for the enrichment and detection of mixed biological solution. In individuals with urinary tract infections or intestinal health issues, the levels of white blood cells (WBCs) and () in urine or intestinal extracts can be significantly elevated compared to normal. The proposed integrated chip, characterized by its low cost, simplicity of operation, fast response, and high accuracy, is designed to detect a mixed solution of WBCs and .

CD4 T lymphocytes play a key role in initiating the adaptive immune response, releasing cytokines that mediate numerous signal transduction pathways across the immune system. Therefore, CD4 T cell counts are widely used as an indicator of overall immunological health. HIV, one of the leading causes of death in the developing world, specifically targets and gradually depletes CD4 cells, making CD4 counts a critical metric for monitoring disease progression.

We analyse mathematical models of blood flow in two simple vascular networks in order to identify structural features that lead to the formation of multiple equilibria. Our models are based on existing rules for blood rheology and haematocrit splitting. By performing bifurcation analysis on these simple network flow models, we identify a link between the changing flow direction in key vessels and the existence of multiple equilibria.
