Ring-opening polymerization of O-carboxyanhydrides (OCAs) can furnish polyesters with a diversity functional groups that are traditionally hard to harvest by lactones. Typical ring-opening catalysts subject unavoidable racemization most OCA monomers, which hampers the synthesis highly isotactic crystalline polymers. Here, we describe an effective bifunctional single-molecule organocatalysis for selective OCAs without epimerization. The close vicinity both activating in same molecule...
The chemistry of α-amino acid N-carboxyanhydrides (NCAs) has a history over 100 years, but precise and efficient ring-opening polymerization methods for NCAs remain highly needed to facilitate the studies polypeptides─that is, mimics natural proteins─in various disciplines. Moreover, universally accepted NCA mechanisms are largely limited "amine" "activated monomer" mechanisms, anionic so far not been invoked. Herein, we show an unprecedented anion-binding catalytic system combining tripodal...
Abstract Anion‐binding can regulate anion transport in chloride channels through dynamic non‐covalent interactions, which gives insights into the designing of new organocatalytic transformations but is surprisingly unexplored polymerization catalysis. Herein, we describe an effective unimolecular anion‐binding organocatalysis where 4‐(dimethylamino)pyridine anchored to a thiourea for ring‐opening O ‐carboxyanhydrides (OCAs) furnish highly isotactic poly(phenyllactic acid) (Ph‐PLA) with...
Tree-ring samples from Chinese Pine (Pinus tabulaeformis Carr.) that were collected in the Taihe Mountains on western Loess Plateau, China, used to analyze effects of climate and drought radial growth reconstruct mean April-June Standardized Precipitation Evapotranspiration Index (SPEI) during period 1730–2012 AD. positively affected tree primarily wet seasons, while temperature negatively dry seasons. Tree responded SPEI at long time scales most likely because trees able withstand water...
To investigate the response mechanism and salt tolerance threshold of three willow seedlings (Salix matsudana, Salix gordejevii, linearistipularis), absorption, transport distribution ions (Na+, K+, Ca2+) were studied under hydroponic conditions with different concentrations (CK, 171, 342, 513, 684 mm) treatment times (1, 3, 5, 8, 11, 15 days). linearistipularis has weakest ability to maintain its apparent shape, while matsudana strongest ability. The plants have a certain Na+ interception...
The response of trees to climate is crucial for the health assessment and protection forests in alpine regions. Based on samples Pinus tabuliformis Abies fargesii, two typical evergreen coniferous species with distinct elevation differences vertical vegetation zones Qinling Mountains, we have developed tree-ring width chronologies southern slope central Mountains China. correlation analysis results showed that radial growth P. A. fargesii responded different climatic factors. Water stress...
Background/Objectives: The largemouth bass (Micropterus salmonides) is a farmed fish of significant economic value, and studying its adaptability crucial for enhancing the benefits aquaculture. changes gene expression pattern to rapidly adapt environmental maintain normal physiological function. Methods: In this study, from two distinct backgrounds—Huzhou Xingtai—were used as experimental materials, they have significantly different breeding conditions. Comparative transcriptomics was...
Porcine reproductive and respiratory syndrome virus (PRRSV) can cause disease failure in pregnant pigs. Previous transcriptome analyses susceptive cells have mainly concentrated on pulmonary alveolar macrophages (PAM) Marc-145 cells, the system. Some studies reported that apoptosis of placental pig endometrial epithelial (PECs) is an obvious sign linked to sows, but mechanism still unknown. In this study, Sn-positive PECs were isolated rates assessed by flow cytometry. PRRSV-infected...
