PEG-DOX, novel pH responsive prodrug nanoparticles
Authors: Li Longyu , Liu Bailun
Published: December 2020

pH responsive prodrug nanoparticles (PEG-DOX) were prepared by attaching free Doxorubicin ( DOX) onto the amphipathic polyethylene glycol-aldehyde (PEG-CHO). The hydrophobic core of PEG-CHO enabled free DOX to be attached, while the hydrophilic outer layer of the carrier enabled the water solubility of the entire structure. This nanocarrier enabled a greater carrying capacity than free DOX, making its circulation time longer. The prodrug remained stable within neutral pH, ensuring its prolonged circulation time, but disassembled rapidly when reaching in the acidic environment of tumor tissues to release the free DOX. The newly designed nanocarriers have the potential to be applied clinically as a future DOX formulation in cancer chemotherapy.

Authors: Sukmawan Sony
Published: December 2020

The diversity and uniqueness of Tenggerese cuisine is a small part of the complexity of gastro-ritual. So far there have not been many comprehensive studies on the gastronomy in Tengger, especially the one in Tenggerese rituals. This article is focused on the ways Karo ritual reveals the aspects of art, aesthetics, socio-culture, history, and science and knowledge. Using the perspective of gastronomic literature, this research found out that the sacredness of traditional Tenggerese cuisine is stabilized in the oral literary piece of Cangkriman. This oral literary piece, which falls into the category of puzzle, becomes an integral part of the performance of Sodoran dance. Sodoran dance in turn becomes an integral part of Karo festival. The symbols of mercy, generosity, thoroughness, detailedness, and ancestor veneration can be seen in the preparation and serving of ritual foods (sesaji [food offerings]) and foods for the participants (cooked rice, side dishes, and snacks) in Karo festival. The preparation and serving of Karo ritual foods show unique culinary aesthetics. The preparation and serving of foods, side dishes, and snacks, which are done by the village institution bethek-sinoman, show a social activity that is full of the value of gotong royong (mutual cooperation). Specifically the genealogy and embryology of the Tenggerese people are symbolized in the traditional snacks of pepes and pasung.

A song can manifest itself as a critical instrument in the vast socio-political atmosphere. Often times a song conceals its real meaning within layers of linguistic elements and through visual communication. Upon the release of Childish Gambino’s This is America (2018), the music video has been assumed widely assumed to contain semiotic elements that criticize the injustice politics of race in America. To dig deeper into this assertion, we use Machin’s Lyrics Analysis (2010) and Kress and van Leeuwen’s Visual Grammar approach (2006) to analyze the illustrated semiotic elements. Both frameworks are two Multimodal Discourse Analysis approaches that explore interdisciplinary analysis in the discourse-oriented research. This article finds that Gambino does question the practice of black discrimination through gun and police violence in present America by utilizing distant words and excessive gestures in his visual communication as a diversion. They are purposefully placed to gain a profound observation from the audience, and thus able to spark a conversation regarding the issue in a greater scale. Furthermore, it is found that This is America applies comical aspects in the visual elements as a layering device. Through humorous semiotic elements, Gambino is discovered to highlight the commodification of black art in his music video.

ABSTRACTThis research aims to describe the use of adverb literally by a native speaker. It is qualitative descriptive research. The main source of this research is the data from one of the online corpora, namely Corpus of Contemporary American English (COCA). There are three steps used in this research, namely the data collection, the data analysis, and the display of the analysis of the results. Based on the data from COCA, this research tries to describe the frequency of the use of adverb literally in COCA and how the adverb is used in the sentence by knowing the particle that follows it. Theories used in this research are the theory of adverb by Pichler (2016) which is supported by the theory by Murphy (1993) and the types of an adverb by Frank (1972). The result shows that the frequency of use of the word literally in COCA amounted to 39.109 contained in the range of 1990 to 2019. The adverb is mostly used in the context of spoken language which is 8.339. The collocation and the concordance lines in COCA are used to find out the particle that follows the adverb literally. The collocation in this research is divided into three classes of words, namely verbs, adjectives, and adverbs. Based on the concordance lines of adverbs in COCA, we can know that the adverb does not have the same position in the sentence. The position of adverb literally can change based on the context of the sentence.
