Due to strong light scattering in tissue, both the spatial resolution and maximum penetration depth of optical-resolution photoacoustic microscopy (OR-PAM) deteriorate sharply with depth. To reduce tissue scattering, we propose to use glycerol as an optical clearing agent in OR-PAM. Our results show that the imaging performance of OR-PAM can be greatly enhanced by optical clearing both in vitro...

BACKGROUND Cold atmospheric-pressure plasma (CAP) has been considered a promising strategy for anti-cancer treatment. Traditionally, CAP was employed to kill cancer cells or tumor tissues by direct irradiation. However, CAP has some disadvantages such as infiltration capacity and storage convenience. Recently, plasma-activated medium (PAM) was used as an alternative strategy to treat cancer cel...

Glutathione (GSH) plays a crucial role in the protection of normal and tumor tissue against the toxic effects of numerous chemotherapeutic drugs. Therefore, the possible therapeutic benefit of thiol depletion in cancer treatment is dependent upon the relative degree to which tumor or normal tissue is sensitized to the toxic effects of subsequent chemotherapy. To address this issue, the followin...

Soil erosion leads to environmental degradation and reduces soil productivity. The use of anionic polyacrylamide (PAM) and synthesized biopolymer (BP) using lignin, corn starch, acrylamide, and acrylic acid were tested to evaluate soil erosion, water quality, and growth of Chinese cabbage (Brassica campestris L.). Each treatment of PAM and BP was applied at 200 kg ha(-1) to loamy sand soil and ...

BACKGROUND The American short form Patient Activation Measure (PAM) is a 13-item instrument which assesses patient (or consumer) self-reported knowledge, skills and confidence for self-management of one's health or chronic condition. In this study the PAM was translated into a Dutch version; psychometric properties of the Dutch version were established and the instrument was validated in a pane...

The Salton Sea is the largest inland water body in California, covering an area of 980 km(2). Inflow to the Salton Sea (1.6 km(3) yr(-1)) is predominately nutrient-rich agricultural wastewater, which has led to eutrophication. Because internal phosphorus release from the bottom sediments is comparatively low and external phosphorus loading to the Salton Sea is high, reduction of tributary phosp...

OBJECTIVES We conducted a randomized trial to test the hypothesis that mother's voice played through a pacifier-activated music player (PAM) during nonnutritive sucking would improve the development of sucking ability and promote more effective oral feeding in preterm infants. METHODS Preterm infants between 34 0/7 and 35 6/7 weeks' postmenstrual age, including those with brain injury, who we...

Glutathione S-transferase (GST) isozymes play a central role in the protection of cells from cytotoxic chemicals and have a putative role in the intrinsic and acquired resistance of tumors to cytotoxic drugs. We have isolated and purified GST isozymes from mouse liver (M. Warholm et al., Biochemistry, 25: 4119-4125, 1986) and analyzed the metabolic products of the reaction of L-phenylalanine mu...

Traditional operating systems are overly restrictive and do not allow user-level applications to modify operating system abstractions. The exokernel operating system architecture safely gives untrusted applications efficient control over hardware and software resources by separating management from protection. Decentralized control, however, makes it very difficult for mutually distrustful appl...

Menispermum dauricum rhizome has been widely used in China to treat various cardiovascular and thrombosis disorders. Some studies have reported that the phenolic alkaloids of Menispermum dauricum rhizome (PAM) have protective effects against brain ischemia injury, but the mechanism of this action remains to be clarified. In the present study, we investigated the possible mechanisms of action of...
