Developing a portable, high-speed, low-cost desktop photoacoustic tomography imaging system
Published 2019“…Usually Nd:YAG-OPO laser is bulky, heavy and needs an optical table to deliver non-fluctuating laser beam and it needs external op- tics (reflectors/prisms) to direct the laser beam onto the sample (there are portable OPO lasers from OpoTek, EKSPLA, and various other companies that do not require optical table but they are more expensive than conventional Nd:YAG-OPO lasers). …”

Roseburia intestinalis generated butyrate boosts anti-PD-1 efficacy in colorectal cancer by activating cytotoxic CD8⁺ T cells
Published 2023“…R. intestinalis or butyrate also significantly improved antiprogrammed cell death protein 1 (anti-PD-1) efficacy in mice bearing MSI-low CT26 tumours. Mechanistically, butyrate directly bound to toll-like receptor 5 (TLR5) receptor on CD8(+) T cells to induce its activity through activating nuclear factor kappa B (NF-& kappa;B) signalling. …”

Optimizing MC-ICP-MS with SEM protocols for determination of U and Th isotope ratios and 230Th ages in carbonates
Published 2019“…Non-linear behavior was not observed in the MasCom SEM with a retarding potential quadrupole in our MC-ICP-MS system when the beam intensity was limited to < ∼1 × 10 6 cps. We performed a series of tests to examine the influence of tuning parameters, peak shift, and operating voltage of the SEM on isotopic measurements. …”
