Mannitol mediates the mummification behavior of larvae infected with .

Introduction: Parasites can facilitate their own spread and reproduction by manipulating insect hosts behavior, as seen in the interaction between and . Infection by leads to the mummification of larvae, but the underlying mechanisms remain mysterious.

Methods: The morphology of infected larvae and fungal growth were first observed.

Neurotransmitter acetylcholine mediates the mummification of -infected larvae.

Parasites can manipulate host behavior to facilitate parasite transmission. One such host-pathogen interaction occurs between the fungus and the ghost moth is involved in the mummification process of infected host larvae. However, the underlying molecular and chemical mechanism for this phenomenon is unknown.

Visualization diagnosis of acute cerebral ischemia sulfane sulfur-activated photoacoustic imaging.

A photoacoustic (PA) imaging probe, HCy-SH, was designed and synthesized. This probe can react rapidly and specifically with sulfane sulfur to produce a strong PA signal. This probe also exhibited low cytotoxicity and biotoxicity.

NIR-II photoacoustic imaging-guided synergistic cancer therapy with a tumor-targeting copper selenide-iron manganese layered double hydroxide nanocomplex.

A novel biodegradable layered double hydroxide-copper selenide nanocomplex was prepared by anchoring copper selenide on manganese iron layered double hydroxide nanosheets. This nanocomplex can specifically release CuSe, Mn and Fe in the tumor microenvironment, which implements NIR-II photoacoustic imaging-guided synergistic cancer therapy under 1064 nm laser irradiation.

Intracerebral Fluorescence-Photoacoustic Dual-Mode Imaging for Precise Diagnosis and Drug Intervention Tracing in Depression.

Unravelling the pathophysiology of depression is a unique challenge. Depression is closely associated with reduced norepinephrine (NE) levels; therefore, developing bioimaging probes to visualize NE levels in the brain is a key to elucidating the pathophysiological process of depression. However, because NE is similar in structure and chemical properties to two other catecholamine neurotransmitters, epinephrine and dopamine, designing an NE-specific multimodal bioimaging probe is a difficult task.

[Spatial-temporal evolution of ecological land and influence factors in Wuhan urban agglome-ration based on geographically weighted regression model].

Ecological land is essential to sustainable development of urban agglomeration. Based on the results of remote sensing image interpretation, we analyzed the spatial-temporal evolution of ecological land in 32 research units of ecological land in Wuhan urban agglomeration in 2000-2005, 2005-2010 and 2010-2015, using the land use transition matrix, exploratory regression analysis, the ordinary least squares (OLS) model, and geographically weighted regression (GWR) model. Then, the best regression model was selected after perfecting the traditional index system of influencing factors by data of the location and quantitative information of companies, enterprises and life services, etc.

Spatio-Temporal Pattern of the Urban System Network in the Huaihe River Basin Based on Entropy Theory.

As complex systems, the spatial structure of urban systems can be analyzed by entropy theory. This paper first calculates the interaction force between cities based on the gravity model, the spatial relationship matrix between cities is constructed using the method of network modeling, and the spatial network modeling of urban system can be calculated. Secondly, the Efficiency Entropy (EE), Quality Entropy (QE), and System Entropy (SE) of urban system network are calculated and analyzed by information entropy.

[Review of CO and CH Emissions from Rivers].

Streams and rivers play a major biogeochemical role in the global carbon cycle and act as hot spots for carbon dioxide (CO) and methane (CH) emissions to the atmosphere, excepting their roles of transporting the water and carbon from the terrestrial environment to the ocean. While carbon gases have been of great global concern, systematic reviews are still scarce. Given recent recognition of the pervasiveness of CO and CH in streams and rivers, this study synthesized existing research and discoveries to identify patterns and controls for riverine CO and CH, knowledge gaps, and research opportunities.

Review on Natural Enemies and Diseases in the Artificial Cultivation of Chinese Caterpillar Mushroom, Ophiocordyceps sinensis (Ascomycetes).

Ophiocordyceps sinensis (syn. Cordyceps sinensis), well known as DongChongXiaCao (DCXC), is one of the most valuable traditional Chinese medicinal species. In this article, we provide a systematic review of natural enemies and diseases encountered in artificial cultivation of DCXC.

[Phenological characteristics of introduced Polygonum viviparum from high altitude to low altitude area].

Objective: To explore the phenological characteristics of Polygonum viviparum introduced from high altitude to low altitude area.

Methods: To introduce the root and seed of Polygonum viviparum from high altitude to low altitude area and collect their growth and phenological data.

Results: In low altitude area, Polygonum viviparum germinated at the beginning of March, grew from March to the end of July, withered during the whole August due to high temperature, recovered from the end of August to the beginning of October, and then withered again due to low temperature.
