Photothermal actuators have attracted increasing attention due to their ability to convert light energy into mechanical deformation and locomotion. This work reports a freestanding, multidirectional photothermal robot that can walk along a predesigned pathway by modulating laser polarization and on-off switching. Magnetic-plasmonic hybrid Fe3 O4 /Ag nanorods are synthesized using an unconventional templating approach. The coupled magnetic and plasmonic anisotropy allows control of the rod orientation, plasmonic excitation, and photothermal conversion by simply applying a magnetic field. Once the rods are fixed with desirable orientations in a bimorph actuator by magnetic-field-assisted lithography, the bending of the actuator can be controlled by switching the laser polarization. A bipedal robot is created by coupling the rod orientation with the alternating actuation of its two legs. Irradiating the robot by a laser with alternating or fixed polarization synergistically results in basic movement (backward and forward) and turning (including left-, right-, and U-turn), respectively. A complex walk along predesigned pathways can be potentially programmed by combining the movement and turning modes of the robots. This strategy provides an alternative driving mechanism for preparing functional soft robots, thus breaking through the limitations in the existing systems in terms of light sources and actuation manners.The term boron-ligand cooperation was introduced to describe a specific mode of action by which certain metal-free systems activate chemical bonds. The main characteristic of this mode of action is that one covalently bound substituent at the boron is actively involved in the bond activation process and changes to a datively bound ligand in the course of the bond activation. Within this review, how the term boron-ligand cooperation evolved is reflected on and examples of bond activation by boron-ligand cooperation are discussed. It is furthermore shown that systems that operate via boron-ligand cooperation can complement the reactivity of classic intramolecular frustrated Lewis pairs and applications of this new concept for metal-free catalysis are summarized.Recent articles report elevated markers of coagulation, endothelial injury, and microthromboses in lungs from deceased COVID-19 patients. However, there has been no discussion of what may induce intravascular coagulation. Platelets are critical in the formation of thrombi and their most potent trigger is platelet activating factor (PAF), first characterized by Demopoulos and colleagues in 1979. PAF is produced by cells involved in host defense and its biological actions bear similarities with COVID-19 disease manifestations. PAF can also stimulate perivascular mast cell activation, leading to inflammation implicated in severe acute respiratory syndrome (SARS). Mast cells are plentiful in the lungs and are a rich source of PAF and of inflammatory cytokines, such as IL-1β and IL-6, which may contribute to COVID-19 and especially SARS. The histamine-1 receptor antagonist rupatadine was developed to have anti-PAF activity, and also inhibits activation of human mast cells in response to PAF. Rupatadine could be repurposed for COVID-19 prophylaxis alone or together with other PAF-inhibitors of natural origin such as the flavonoids quercetin and luteolin, which have antiviral, anti-inflammatory, and anti-PAF actions.
We describe and compare eating disorder (ED) psychopathology prevalence in Canadian females and males across five age groups.

This secondary data analysis study used the Eating Disorder Examination Questionnaire (EDE-Q) to assess ED psychopathology in 1,316 Alberta community-based female and male participants, aged 15 to 71.

Overall, 15.3% of female and 8.2% of male participants reported clinically-significant ED disturbances. Female participants reported greater global ED psychopathology than male participants, except older men and women aged 65-71, who reported similar, relatively low levels of global ED psychopathology. Women aged 65-71 endorsed less global ED psychopathology than younger females. More females than males reported regular binge eating and self-induced vomiting, whereas other ED behaviors were endorsed at similar rates.

This large-scale study, the first involving a Canadian sample, contributes to a small literature on ED psychopathology in community-based samples. The finding that 15% of female and 8% of male Albertans aged 15 to 71 endorsed clinically-significant ED disturbances is concerning; however, women aged 65-71 reported lower ED psychopathology than younger females. Gender and age differences were observed in global ED psychopathology. Routine ED screening of non-clinical adolescents and adults is warranted to permit prevention and early intervention.

Paraquat and diquat are widely used in agricultural production in many countries, which are very toxic to human beings. Paraquat can be detected in some diquat solution sold in the market. The blood concentration of paraquat or diquat is an important indicator for clinical diagnosis of paraquat or diquat poisoning. So, it is very meaningful to develop a method for simultaneous determination of paraquat and diquat in human plasma.

To develop and validate a HPLC-DAD method for simultaneous determination of paraquat and diquat in human plasma and to apply it in the acute poisoning patients by these two herbicides.

Paraquat and diquat were simultaneously determined by HPLC-DAD. Ceralasertib The plasma was treated using Waters OASIS
Column and then separated on a Thermo Hypersil GOLD (250×4.6mm, 5μm) Column with the mobile phase consisted of 75mmol/L sodium heptane sulfonate (containing 0.1mol/L phosphoric acid, pH 3.0) and acetonitrile (8713, vv) at a flow rate of 1.0mL/min. The full-wavelength scanning was 200-400nm, and the detection wavelength of paraquat and diquat was 257nm and 310nm, respectively.
