Physiological responses of typical subtropical landscape shrubs to artificial light at night.

Artificial light at night is rapidly spreading and has become an important component of global change. Although numerous studies have focused on its potential ecological impacts, the physiological response mechanisms of landscape plants to artificial light at night have rarely been quantified. With common landscape shrubs in subtropical regions of China, , and , as test materials, we exa-mined the responses of antioxidant enzyme system and biomass in the light environment at night under different light quality (yellow light, white light) with different light intensities (20, 40, 60 lx) .

Astrocytic connexin 43 deletion ameliorates SNI-induced neuropathic pain by reducing microglia activation.

Neuropathic pain (NP) is a chronic disease caused by damage to the peripheral or central nervous system. Connexin 43 (Cx43), the primary connexin expressed by astrocytes, has been reported to be significantly increased in NP. However, the roles and mechanisms of Cx43 in the development and maintenance of NP remain largely unknown, while microglia activation has been commonly regarded as a key factor of NP.

The near-infrared dye IR-61 restores erectile function in a streptozotocin-induced diabetes model via mitochondrial protection.

This study aimed to evaluate the therapeutic effect of IR-61, a novel mitochondrial heptamethine cyanine dye with antioxidant effects, on diabetes mellitus-induced erectile dysfunction (DMED). Eight-week-old male Sprague-Dawley rats were intraperitoneally injected with streptozotocin (STZ) to induce type 1 diabetes. Eight weeks after STZ injection, all rats were divided into three groups: the control group, DM group, and DM + IR-61 group.

Effect of the substitution pattern on the intramolecular charge-transfer emissions in organoboron-based biphenyls, diphenylacetylenes, and stilbenes.

Three series of organoboron-based molecules, including biphenyls 1a-c, diphenylacetylenes 2a-c, and stilbenes 3a-c, in which the electron-accepting boryl and the electron-donating amino groups are introduced at different positions, have been comprehensively investigated to explore the effect of the substitution pattern on the intramolecular charge-transfer emissions. In cyclohexane solution, the change of substitution pattern from p,p' to o,p' by introduction of boryl at the lateral o-position rather than the terminal p-position leads to bathochromism in the absorption and emission spectra. With further variation of the amino position from the terminal p'-position in o,p'-substitution to the lateral o'-position in an o,o'-substitution pattern, a blueshift was observed in the absorption owing to the less-efficient conjugation extension of the amino group as the result of sp(3) hybridization.

[Degradation and bioaccumulation characteristics of ciprofloxacin in soil-vegetable system].

A pot experiment was conducted to investigate the effects of applying ciprofloxacin (CIP) on the growth of flowering Chinese cabbage (Brassica campestris), radish (Raphanus sativus), tomato (Solanum lycopersicum) and long bean (Vigna unguiculata), the bioaccumation of CIP in the vegetables, and the degradation of the antibiotics in soil. The results showed that applying 5, 30 and 75 mg x kg(-1) of CIP had no significant effects on the plant biomass of flowering Chinese cabbage, tomato and long bean, but the high concentration of CIP (> or = 30 mg x kg(-1)) inhibited the radish growth significantly. The degradation of CIP in soil was fast at beginning, but slowed down gradually since then.

[Effects of lead stress on the growth and reproduction of Spodoptera litura fabricius (Lepidoptera:Noctuidae)].

Standard artificial diet was added with different concentration lead (Pb) to feed herbivorous insect Spodoptera litura larvae to study their growth and reproduction under the effects of Pb stress.
