Abstract

Neuroinflammation, an inflammatory response within the central nervous system (CNS), plays a critical role in various neurological disorders, including neurodegenerative diseases. Alpha linolenic acid (ALA), an essential omega-3 polyunsaturated fatty acid, has shown promising health benefits due to its antioxidant and anti-inflammatory properties. This article aims to thoroughly examine the potential effects of ALA in reducing neuroinflammation, emphasizing its roles as an anti-inflammatory and antioxidant agent. The review focuses on studies published between 2018 and 2023, sourced from reputable academic databases such as PubMed, Semantic Scholar, Google Scholar, and ScienceDirect, with nine key papers selected. The findings indicate that ALA significantly mitigates neuroinflammation by decreasing reactive oxygen species (ROS) via the Nrf-2/HO-1/JNK signaling pathway. Additionally, ALA reduces inflammatory cytokines by inhibiting p-JNK activation, disrupting lipid rafts, blocking the pro-inflammatory transcription factor NF-κB, and altering cell membrane phospholipid composition. The review concludes that ALA may have potential therapeutic effects in reducing neuroinflammation through its antioxidant and anti-inflammatory actions, offering possible benefits for various neurological conditions, including Alzheimer's and Parkinson's diseases.

Abstract

One of Indonesia's local wisdom is Timba Nyale. The Timba Nyale tradition is held every year in March-April, where the people of Sumba flock to the coast while waiting for the appearance of Nyale. This research aims to understand the meaning of Timba Nyale cultural studies and analyze the importance of Science in Nyale to be used as authentic Science learning material. This research was conducted in Buku Bani Village, Ate Dalo Village, Kodi District, Southwest Sumba Regency, East Nusa Tenggara. The method used is a qualitative method using grounded theory. Data collection was done through interviews, observation, documentation, and literature study. The results showed that Nyale has a significant meaning which is a marker for the success or failure of the harvest for the people of Sumba. Nyale in the Sumba tradition also has scientific values, including the importance of preservation and maintaining the conservation of species called Nyale. Analysis of learning outcomes in Animal Anatomy and Physiology courses in one of the private universities in Sumba shows that Nyale can be studied in the practicum of animal anatomy and physiology courses.

Abstract

Lemon pepper does not only have a unique taste but also has some active compounds, which has anti-inflammatory activity. This study intended to investigate the anti-inflammatory effect of lemon pepper nanoemulsion on carrageenan-induced Wistar rats. This experimental study used Twenty-five male Wistar rats that were grouped into five different groups, including control, standard, lemon pepper nanoemulsion dose of 25, 50, and 75 mg/ kgBW. Initially, all rats received air injection in the back area for 5 days to form an air pouch. After that, all rats were injected with 1% carrageenan solution, and received treatment based on the groups for 48 hours via oral route. Then, it counted the number of white blood cells by Giemsa Stain that was expressed as a number of cells per High Power Field (HPF). The increasing of Lemon pepper nanoemulsion dose significantly decreased the number of leucocytes in the carrageenan aspiration after 48 hours of treatment (P-Value < 0.001). The lowest number of leucocytes was found in the Lemon Pepper Nanoemulsion dose of 75 mg/kgBW (2.40 leukocytes per HPF). Hence, it can be deducted that the lemon pepper nanoemulsion has an anti-inflammatory effect, especially at a dose of 50-75 mg/kgBW.

Abstract

This article examines how in an educational setting communication skills can enhance critical thinking abilities through guided inquiry. Human resources (HR) must be improved in light of the Industrial Revolution 4.0, but obstacles to learning include low student engagement, a lack of enthusiasm, and a lack of critical thinking abilities. Although communication skills are frequently a barrier, guided inquiry is recognized as a learning model capable of advancing students' critical thinking abilities. The activity steps in guided inquiry are covered in this article, along with pertinent communication skills such as explanation of delivery, material mastery, group interaction, and responding. It is highlighted how critical thinking abilities and communication skills are linked in 21st-century learning. It is widely acknowledged that effective verbal, written, and listening communication skills are essential for guided inquiry. Source triangulation was employed as a qualitative research method with a post-positivism approach to gather data. The article emphasizes how communication skills help students develop their critical thinking abilities by enabling them to assess and connect information to a wider context in addition to gathering and analyzing it. The conclusion highlights the need of communication abilities
