This work aims to study the construction of reverse aspirin-loaded micelles prepared from amphiphilic PEG-PLA-SA triblock copolymers and the optimization of the preparation process. Using polyethylene glycol (PEG) as the initiator, ring-opening polymerization of L-lactide (L-LA) was used to prepare PEG-PLA diblock copolymers. Final product PEG-PLA-SA triblock copolymers were prepared by the reaction of stearic acid (SA) and PEG-PLA catalyzed by 4-dimethylaminopyridine (DMAP) and N,N'-Dicyclohexylcarbodiimide (DCC). Fourier transform infrared spectrometer (FT-IR) was used to characterize the product structure. PEG-PLA-SA triblock copolymers self-assembled in toluene/ethanol/water system to form reverse micelles, which could encapsulate aspirin into a hydrophilic core. Dynamic light scattering (DLS) and transmission electron microscopy (TEM) were used to determine the size and morphology of reverse micelles. The results showed that the reverse micelles are spherical, with a particle size of less than 70 nm. Response surface analysis method was applied to optimize the preparation process of PEG-PLA-SA. In vitro drug release was achieved by embedding reverse aspirin-loaded micelles in the biocompatible membrane in phosphate buffer saline (PBS) at 37°C. In the first 8 h, the drug release rate of the triblock copolymers was slower than that of the diblock copolymers. After 8 h, the drug release rate of both tended to be flat. The stability of aspirin-loaded reverse micelles was studied through accelerated test. These results indicate that reverse micelle PEG-PLA-SA may be a promising carrier for hydrophilic drugs like aspirin.This study examines bilingual effects in Spanish-English bilingual children with good maintenance of the minority language. The present study compares the performance of a group of Spanish-monolingual children (MON; n=30) with two groups of Spanish-speaking bilingual children (Low English proficiency group LEP; n=36; High English proficiency group, HEP; n=36) on the elicited productions of Spanish articles and object clitics. Our results suggest that children with LEP performed significantly lower than MON children of the same age on both articles and clitics in Spanish. However, children with HEP, who were a year older on average, performed similarly to the MON group. Both groups of bilingual children produced errors of clitic omission and substitution, but these errors were minimal in the MON group. The results suggest that Spanish clitics and articles are vulnerable to bilingual effects for English/Spanish speaking children with good Spanish maintenance.A third species of Hiroshia László, Ronkay & Ronkay, 2001, H. shennongjiaensis Ronkay, Ronkay & Han, sp. nov. is described from Hubei Province in China. this website The adult and the male genitalia of the new species are illustrated and compared with those of its congeners, H. albinigra László, Ronkay & Ronkay, 2001 and H. nanlingana Zhuang, Owada & Wang, 2014; an identification key based on the male genitalia is presented.The southwestern Andes of Peru harbors a hidden taxonomic diversity of Lepidoptera. Here a new leaf-mining species of Gracillariidae (Lepidoptera) is described, Phyllocnistis furcata Vargas & Cerdeña, sp. nov., from a dry Andean valley of southern Peru, at 2400 m above sea level. The morphological aspects of adults (male and female) and the immature stages associated with Baccharis alnifolia Meyen & Walp. (Asteraceae) are given, under optical microscopy and scanning electron microscopy. DNA barcodes show that its nearest neighbor is the Atlantic Forest species Phyllocnistis ourea Brito & Moreira, 2017 that feeds on Baccharis anomala DC. The importance of morphological characters from immature stages for diagnosis among congeneric species is also discussed. Phyllocnistis furcata represents the fourth species of Phyllocnistis Zeller for Peru, and first record from the south of Peru for the genus.Two new species of the genus Trispinaria Quicke, 1986, from Vietnam, viz. T. seminigra Long, sp. nov. and T. vietnamica Long, sp. nov., are described and fully illustrated. Additionally, this is the first record of the genus Trispinaria in Vietnam. A checklist with distributions of previously described species of the genus Trispinaria is given. Comparative characters of the Vietnamese species are provided and modified key couplets are provided to facilitate their identification.Two new species of Bohayella Belokobylskij, 1987 from Costa Rica are described Bohayella geraldinae Kang, sp. nov. and Bohayella hansoni Kang, sp. nov. These are new distribution records for the genus in the Neotropical region. In addition, a key to species of the genus Bohayella of Costa Rica is presented. The current work elevates the number of species included in Bohayella from nine to eleven.The micropolydesmoid millipede family Haplodesmidae is here recorded from Cambodia for the first time through the discovery of the first, new species of the genus Eutrichodesmus Silvestri, 1910 E. cambodiensissp. nov. This new species is described from two limestone habitats in Kampot Province, based on abundant material. It is easily distinguished from all related congeners by the following combination of characters body greyish-brown; limbus roundly lobulate; solenomere partially divided from acropodite by a digitiform lobe, but without hairpad. Brief remarks on the previously-proposed "pecularis-group" are provided and a second group, the "demangei-group", is established and discussed on the basis of morphological evidence, updating the number of recognised species groups of Eutrichodesmus to two. Detailed morphological illustrations, photographs and a distribution map, as well as remarks on its habitat and mating behaviour of the new species are presented. Furthermore, the current distributions of all 55 presently-known species of Eutrichodesmus are provided and a key to all 23 species that occur in mainland Southeast Asia is given.In this study, four new dextral camaenid from China are reported, based on shell morphology, reproductive system anatomy, and molecular phylogenetic analyses Camaena funingensis Zhou, Wang & Lin, sp. nov., Camaena gaolongensis Zhou, Wang & Lin, sp. nov., Camaena maguanensis Zhou, Wang & Hu, sp. nov., and Camaena yulinensis Zhou, Wang & Hu, sp. nov. Detailed descriptions of the morphological characteristics including shells and genitalia, DNA sequences, and living environments of the four new species are provided, with further comparisons with congeners.
