Abstract

Lipopolysaccharide (LPS) is a major component of a gram-negative bacterial wall that is widely used and well-established to induce inflammation in vitro. In addition, the in vitro model using RAW 264.7 cells is the most commonly applied in screening the anti-inflammatory and elucidating the pathophysiology of inflammation-based disease, as well.  However, there is still limited data on the efficacy of different doses of LPS in inducing inflammation in RAW 264.7 cells. This study aimed to evaluate the effect and safety of LPS at various doses in RAW 264.7 cells. RAW 264.7 cells were exposed to LPS at different dose ranges (10ng/mL-10µg/mL) for 24 hours. The nitric oxide (NO) release as inflammatory responses and viability test were evaluated using Griess assay and CCK-8 assays, respectively. The result showed that NO production was increased at different doses of LPS compared to the control although not significant. Whereas, All LPS-treated RAW 264.7 cells tended to increase but not significantly compared to the control groups. This study showed that the LPS treatment effectively induced inflammation in RAW 264.7 cells as shown by NO production and was considerably safe as the viability was comparable between LPS and control group for RAW cells 264.7 at least up to 10µg/mL for 24 hours.

Abstract

The study examined the influence of family and school environment on the English language skills of early childhood children at “TK Al-Falah Balombong”. The main objective of this research was to identify the factors hindering English language learning in that place, as well as to determine the extent of children’s interest to know, learn, understand, and master English. This research used a qualitative method with a descriptive approach. We found that the family and school environment at “TK Al-Falah Balombong” was not optimal in supporting English language learning. This could be seen from the language they often used at home and in their community, their local language and Indonesian, as well as the gadgets provided by their parents that did not focus on English language learning. The school also lacked competent English language teachers and adequate supporting facilities. Despite these limitations, the children showed high enthusiasm when the researchers introduced English through engaging methods such as songs and animations. To optimize this potential, interactive approaches, competent teachers, and parental support are needed to facilitate their children's English learning.

The implementation of this study was conducted at SMA 3 Majene which is a boarding school student. This study used a quantitative descriptive method where there were 28 samples from 58 populations who participated in the data collection process. The instrument used is a test consisting of a pre-test and post-test, and an observation guide. From the results of observation, the prominent skill was speaking skill which was seen from several activities, namely providing material, morning talk, talk show, talent night, and treasure hunt consisting of five activities, namely Spelling bee, Word Guessing, Constructing Sentences, Once Upon A Time, Arrange the picture. This was in line with the test results which showed that this program could improve students' speaking skills with an average score of -0.767. The researchers concluded that this program can improve speaking, but it did not have much effect on other skills. Therefore, researchers recommended that further research can construct more active activities furthermore all skills can be covered. This research can provide benefits for pre-service teachers who can use this research as a reference for carrying out activities in the classroom. It was also useful for future researchers who wanted to develop English area programs in other places or by using different indicators.
