Effective use of species distribution models can assess the risk of spreading forest pests. In this study, based on 434 occurrence records and eight environmental variables, an ensemble model was applied to identify key environmental factors affecting the distribution of Chevrolat, 1852 and predict its potential habitat and its relative areas of change under current and future climatic conditions. The results indicate that humidity, solar radiation, topography, and human activities were the main factors influencing the distribution of .

Background: Non-small cell lung cancer (NSCLC) shows the highest morbidity among malignant tumors worldwide. Despite improvements of diagnosis and treatment, patient prognosis remains unfavorable. Therefore, there is a need to discover a novel treatment strategy for NSCLC.

The faunal composition, host relationships and biological information of the subfamily Cassidinae (Coleoptera, Chrysomelidae) remain poorly known in many Chinese regions. Based on the seven-year field survey, faunal composition and host associations of Cassidinae beetles were systematically compiled for Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province. In particular, through direct field observations, detailed biological information, such as life history and behavioural features and host plants were first recorded for 56 species of Cassidinae beetles.

Rationale: Titanium mesh is one of the most widely used implant materials applied in cranioplasty; however, it has been reported to encounter the risk of progressive scalp thinning and implant exposure over time. Here we present 2 cases of exposed titanium mesh (TM) and unusual phenomena of full-thickness skin regeneration beneath the mesh.

Patient Concerns: Two patients, 1 with an 8-year and 1 with a 2-year history of implant exposure after cranial TM implantation.

Few systematic studies have been conducted on the faunal composition and food web structure of Cassidinae of China. During 2013-2019, we systematically investigated Cassidinae beetles and their host plants in the southern Guangxi. A total of 2,255 Cassidinae individuals from 66 species, 23 genera and ten tribes were collected in southern Guangxi.

The utilization of carbon dioxide (CO) has drawn much attention because of the increasing serious environmental problems. In order to promote the cycloaddition reaction of CO to epoxides, a new synthesis strategy for friendly nonmetal catalyst to combine polymeric ionic liquid (PIL) with mesoporous silica (mSiO) was proposed. By thorough characterizations, those catalysts (mSiO-PIL-n, n = 1, 2, 3, 4) were verified that PIL with multiply catalytic active sites such as carboxyl group, imidazole ring and Br, was mainly anchored in mesoporous SiO structures.

Much endeavor has been devoted to efficient heterogeneous catalysts for carbon dioxide (CO) conversion to high-value chemicals. Meanwhile, the cycloaddition of CO to epoxides is considered as a green and atom-economy reaction to produce cyclic carbonates. Herein, a series of K, B co-doped CN with various doping contents (K, B-CN-X) were developed by simple one-step calcination of melamine and KBH.

Aim: To investigate the effects of polarizing cardioplegia solution with sodium channel inhibitor tetrodotoxin (TTX) on intracellular free Na+ concentration ([Na+]i) in isolated cardiomyocytes of rat.

Methods: Ventricular myocytes with beating were isolated from adult rat hearts by enzymatic dissociation, randomly created in group base, group STH2 (contrast group of ischemia/reperfusion) and group TFX (treated group). Both Group STH2 and group TTX were arrested by St.

Objective: To investigate the protective effects of polarizing cardioplegia with Na(+) channel inhibitor tetrodotoxin (TTX) in ex vivo rat heart preservation.

Methods: Using a Langendorff preparation, Wistar rat hearts were arrested and preserved with St. Thomas (STH) solution (n=10) or with polarizing cardioplegia (TTX, n=10) for 7 h in hypothermic storage (10 degrees Celsius).
