The intratumoral oxygen level can be replenished during the PTT cycle for the next round of PDT to generate 1 O2 . The working principle and phototherapy efficacy are preliminarily demonstrated in living cells and tumor-bearing mice, respectively.

To establish an artery and venous sinus occlusion image score (AVOIS) which is compatible in both cerebral arteries and venous system diseases.

A total of 188 consecutive patients with the final diagnosis of anterior circulation infarct (ACI) and 56 consecutive patients with cerebral venous and sinus thrombosis (CVST) were retrospectively studied. The AVOIS was developed based on the severity of occlusive changes of main intracranial arteries and venous sinuses (present=0, partial occlusion=1, absent=2), and divided into four groups (CVST group 0, 1-5, 6-10, >10. ACI group 0, 1-5, 6-10, >10) arbitrarily. A receiver operating characteristic (ROC) curve was applied to discover the sensitivity and specificity of AVOIS. click here The National Institutes of Health Stroke Scale (NIHSS), Clot Burden Score (CBS) were set as the reference. Logistic regression models were developed to adjust for baseline clinical variables and AVOIS. Length of hospital stay (LOS) was also evaluated using the Kaplan-Meier estimator.

For the CVST group, a positive correlation between AVOIS and NIHSS was discovered (Spearman’s ρ=0.54, p<0.001). For the ACI group, ROC showed relatively high sensitivity (84.8%) and specificity (81.8%). Besides, the probability of time to discharge was significantly different among the AVOIS subgroups as well (p<0.001).

The AVOIS can be used to evaluate the treatment of patients with acute stroke caused by cerebral venous sinus thrombosis and anterior circulation large vessel occlusion. It is a reliable and convenient method that may help prompt prognosis and guide the treatment of individual patients.

However, the reported high performance rTENG all have complex structures for output enhancement. In this work, an ultra-simple strategy to build high performance rTENG is developed. With only one small paper strip added to the conventional structure, the output of the TENG is promoted hugely. The voltage is triplicated to 2.3 kV, and the current and charge are quintupled to 133 µA and 197 nC, respectively. The small paper strip, with the merits of ultra-simplicity, wide availability, easy accessibility and low cost, functions as a super-effective charge supplement. This simple and delicate structure enables ultra-high durability with the 2.3 kV voltage output 100% maintained after 1 000 000 cycles. This charge supplementary strategy is universally effective for many other materials, and decouples the output enhancement from any friction or contact on the metal electrodes, emphasizing a critical working principle for the rTENG. Atmospheric cold plasma is generated using the paper strip rTENG (ps-rTENG), which demonstrates strong ability to do bacteria sterilization. This simple and persistent charge supplementary strategy can be easily adopted by other designs to promote the output even further.Effective and reliable encapsulation of phase change materials (PCMs) is essential and critical to the high-performance solar-thermal energy harvesting and storage. However, challenges remain pertaining to manufacturing scalability, high efficiency in energy storage/release, and anti-leakage of melted PCMs. Herein, inspired by natural legume, a facile and scalable extrusion-based core-sheath 3D printing strategy is demonstrated for directly constructing bean-pod-structured octadecane (OD)/graphene (BOG) phase change microlattices, with regular porous configuration as well as individual and effective encapsulation of OD “beans” into highly interconnected graphene network wrapping layer built by closely stacked and aligned graphene sheets. The unique architectural features enable the ready spreading of light into the interior of phase change microlattice, a high transversal thermal conductivity of 1.67 W m-1 K-1 , and rapid solar-thermal energy harvesting and transfer, thereby delivering a high solar-thermal energy storage efficiency, and a large phase change enthalpy of 190 J g-1 with 99.1% retention after 200 cycles. Most importantly, such encapsulated PCMs feature an exceptional thermal reliability and stability, with no leakage and shape variation even at 1000 thermal cycles and partial damage of BOG. This work validates the feasibility of scalably printing practical encapsulated PCMs, which may revolutionize the fabrication of composite PCMs for solar-thermal energy storage devices.Phytochemical investigation of Walsura trichostemon leaves led to the isolation of a new apotirucallane-type triterpenoid, 11,25-dideacetyl-16-hydroxytrichostemonate (1), along with two known apotirucallane-type triterpenoids (2 and 3), two known tirucallane-type triterpenes (4 and 5), and two known steroids (6 and 7). Their structures were identified by intensive analysis of 1D and 2D nuclear magnetic resonance, infrared, and mass spectrometry data, which were compared with data reported in the literature. Compounds 2, 3, and 5 exhibited moderate antibacterial activity against Pseudomonas aeruginosa (minimum inhibitory concentration (MIC) value 64 μg/mL), and compound 4 showed weak antibacterial activity against P. aeruginosa (MIC 128 μg/mL). Furthermore, compound 5 displayed activity against Bacillus cereus (MIC 64 μg/mL). In addition, compound 4 showed stronger α-glucosidase inhibitory activity than the control, acarbose. The active compound 4 was subjected to molecular docking experiments using AutoDock4 and revealed precise interactions with the active gorge of the enzyme through hydrogen bonding, supporting the in vitro results.
