Significance: Photoacoustic (PA) imaging is an emerging biomedical imaging modality that can map optical absorption contrast in biological tissues by detecting ultrasound signal. Piezoelectric transducers are commonly used in PA imaging to detect the ultrasound signals. However, piezoelectric transducers suffer from low sensitivity when the dimensions are reduced and are easily influenced by electromagnetic interference.

An animal model of NSCLC was established, and BEAS-2b, H1299, Lewis, and T cells were used for subsequent experimental verification. The level of miR-196b-5p was detected by quantitative real-time polymerase chain reaction.

The current systematic analysis and meta-analysis was aimed to evaluate the association between radiation-induced lymphopenia (RIL) and survival of women with cervical cancer (CC). PubMed, Embase, Web of Science, and Cochrane Library were searched for relevant cohort studies comparing survival between women with CC who developed versus not developed RIL after radiotherapy. We pooled the results using a random-effects model that incorporates heterogeneity.

This ecosystem also has a great ecological importance, but is highly susceptible to anthropogenic disturbances. The balance of mangrove ecosystem depends largely on the microbial communities in mangrove sediments.

The structural and optical properties of the SnO(2) nanorods were investigated using x-ray powder diffraction, transmission electron microscopy, high-resolution transmission electron microscopy, and infrared, Raman and photoluminescence spectroscopy. The experimental results show that lithium addition plays a critical role in the formation of SnO(2) nanorods, and the correlation between the surface energy change and morphological evolution of this material is also discussed.

Novel silica-coated iron-carbon composite particles were prepared to be used in the targeting therapy as a drug carrier. The composite particles with diameter of 200-300 nm were obtained successfully via high-energy planetary ball milling and hydrogen reduction processes. The composite particles possess the advantages of activated carbon and magnetic Fe, exhibiting excellent drug adsorption and desorption abilities as well as powerfully magnetic targeting.
