Acrylamide (ACR) is a widely used industrial chemical. However, it is a dangerous compound because it showed neurotoxic effects in humans and act as reproductive toxicant and carcinogen in many animal species. In the environment, acrylamide has high soil mobility and may travel via groundwater. Phytoremediation is an effective method to remove the environmental pollutants, but the mechanism of plant response to acrylamide remains unknown. With the purpose of assessing remediation potentials of plants for acrylamide, we have examined acrylamide uptake by the model plant Arabidopsis grown on contaminated substrates with high performance liquid chromatography (HPLC) analysis. The result revealed that acrylamide could be absorbed and degraded by Arabidopsis. Further microarray analysis showed that 527 transcripts were up-regulated within 2-days under acrylamide exposure condition. We have found many potential acrylamide-induced genes playing a major role in plant metabolism and phytoremediation.

The denatured bovine serum albumin (dBSA) is coupled with the CdTe/CdS quantum dot and the resulting CdTe/CdS@dBSA complex is assembled and retained in the poly(n-isopropyl acrylamide) (PNIPAM) hydrogel via regulating temperature and pH to form the CdTe/CdS@dBSA-PNIPAM fluorescence hydrogel substrate, which is able to adsorb and sense cadmium ions (Cd). Based on this fluorescence hydrogel, a fluorescence and colorimetric dual-mode detection system is established to quantitatively detect Cd with a limit of detection (LOD) of 2.88 nM for fluorescence detection and 11.

Succinyldiamide derivatives are important structural motifs in various natural products, pharmaceuticals, and functional materials. Herein, a novel, mild, and environmentally friendly method was developed for synthesizing functionalized succinyldiamides each containing a quaternary carbon center. This strategy was designed to involve photocatalytic decarboxylation of readily available oxalic monoamide using a non-precious metal photocatalyst, 4CzIPN, followed by a free-radical addition/Smiles rearrangement cascade reaction of -aryl--(arylsulfonyl)acrylamides.

Hydrogels are promising materials for wearable electronics, artificial skins and biomedical engineering, but their limited stretchability, self-recovery and crack resistance restrict their performance in demanding applications. Despite efforts to enhance these properties using micelle cross-links, nanofillers and dynamic interactions, it remains a challenge to fabricate hydrogels that combine high stretchability, self-healing and strong adhesion. Herein, we report a novel hydrogel synthesized the copolymerization of acrylamide (AM), maleic acid (MA) and acrylonitrile (AN), designed to address these limitations.

Cryptosporidiosis is an infection induced by the single-celled protozoan Cryptosporidium parasite. This parasite commonly infects the intestines of humans and animals, leading to gastrointestinal symptoms such as diarrhea, stomach cramps, nausea, and vomiting. Cryptopain protein, a type of cysteine protease found in the genome of plays an important role in cell invasion and its survival.

Background: Uncommon EGFR mutations are a kind of heterogeneous group of mutations with various responses to EGFR-TKIs and are often excluded from most prospective clinical trials. In this real-world retrospective study, we retrospectively compared the efficacy and safety of chemotherapy or various generations of EGFR-TKIs as first-line therapy in NSCLC Chinese patients harboring non-ex 20 ins uncommon EGFR mutations.
Methods: We enrolled 139 NSCLC patients with non-ex 20 ins uncommon EGFR mutations in this study retrospectively.
