Abstract

RNA virus infections pose a significant challenge to vertebrate health due to their high mutation rates and capacity for rapid evolution. This review aims to synthesize the understanding of the central role of the adaptive immune system in recognizing, controlling, and eliminating RNA virus infections. Through a narrative literature review approach, an in-depth analysis of the two main pillars of adaptive immunity—humoral and cell-mediated immunity—was conducted. The findings indicate that humoral immunity, mediated by B cells and antibodies, is crucial for neutralizing extracellular virus particles, thereby preventing viral attachment and entry into host cells. In parallel, cell-mediated immunity, driven by cytotoxic T cells (CD8+), is essential for eliminating already infected cells, while helper T cells (CD4+) act as key coordinators that regulate the entire response. A fundamental advantage of this response is the formation of immunological memory, which provides long-term protection and serves as the basis for vaccine efficacy. Nevertheless, the immune system faces a continuous challenge from viral evasion strategies, such as antigenic drift, which fuels an evolutionary arms race. A comprehensive understanding of this dynamic interaction is vital for the development of more effective next-generation vaccines and antiviral therapies.

Abstract

Amphibians are important bioindicators of environmental health due to their sensitivity to changes in habitat quality, particularly during the embryonic phase. This study aimed to observe and compare the effects of varying temperature and pH conditions on the embryogenesis of the frog, Rana sp. A laboratory experimental method was employed with several treatment groups: a control group (25°C, pH 7.0), low temperature (20°C), high temperature (30°C), and acidic pH (pH 5.0). Observed parameters included developmental rate, mortality rate, and morphological abnormalities. The results showed that the control group underwent normal development with a survival rate exceeding 95%. The low-temperature treatment significantly slowed the developmental rate, whereas high temperature accelerated development but caused mass mortality and severe malformations. The acidic pH condition (pH 5.0) proved to be lethal, resulting in nearly 100% embryonic mortality at an early developmental stage. It was concluded that the embryonic development of Rana sp. is highly dependent on optimal temperature and pH conditions. Deviations from this ideal range lead to serious developmental disruptions, confirming the vital role of frog embryos as sensitive indicators of environmental changes such as global warming and water acidification.

Abstract

Ultraviolet (UV) radiation is a primary environmental mutagen that threatens genomic stability by causing various types of DNA damage. This study aimed to quantitatively analyze the effect of UV-B radiation on the induction of DNA damage, repair efficiency, and its consequent impact on the cellular mutation rate. Using human keratinocyte (HaCaT) cell cultures, cells were exposed to varying doses of UV-B radiation (0-200 J/m²). The level of DNA damage, specifically cyclobutane pyrimidine dimers (CPDs), was measured using an ELISA method, while the mutation rate was evaluated through the HPRT locus assay. The results showed that UV-B exposure caused a significant and dose-dependent increase in the number of CPDs. Although cells demonstrated a time-dependent capacity for DNA repair, this process was incomplete, especially at high doses, leaving persistent DNA lesions. The presence of this unrepaired damage directly correlated with a dose-dependent increase in mutation frequency. In conclusion, this study demonstrates a clear mechanistic pathway from UV exposure to DNA damage, which is then processed through incomplete repair into permanent genetic mutations. This process forms the molecular basis for the initiation of photocarcinogenesis, affirming the crucial role of UV protection in maintaining genomic integrity and preventing skin cancer.

Abstract

The catalase enzyme is a vital antioxidant enzyme whose activity is influenced by environmental factors such as temperature. This research aimed to investigate the effect of temperature variation on the activity of the catalase enzyme isolated from chicken liver (Gallus gallus domesticus). A laboratory experimental method was used by measuring the catalase activity in a crude extract of chicken liver. The enzyme extract was incubated at five different temperatures: 5°C, 27°C, 37°C, 47°C, and 57°C. Enzyme activity was determined spectrophotometrically by measuring the decomposition rate of the hydrogen peroxide (H2O2) substrate. The results showed that temperature has a significant influence. Enzyme activity was observed to be low at 5°C, then increased with rising temperature, reaching its peak (optimal) activity at 37°C. At higher temperatures (47°C and 57°C), the enzyme's activity decreased sharply. The decrease in activity at low temperatures was caused by reversible inactivation, whereas at high temperatures it was caused by irreversible thermal denaturation. The optimal temperature of 37°C indicates the enzyme's adaptation to function efficiently at the normal physiological temperature of chickens. In conclusion, temperature is a critical factor that controls the catalytic function of the catalase enzyme.

Abstract

This study aims to examine the effectiveness of Augmented Reality (AR)-based learning media in enhancing students’ motivation in Science (IPA) learning at the junior high school level. The research background lies in the low learning motivation of students, as Science is often perceived as abstract and difficult to understand. A quasi-experimental method with a Nonequivalent Control Group Design was employed, involving two eighth-grade classes as the experimental and control groups. The research instrument was a motivation questionnaire that had been tested for validity and reliability. Data analysis results revealed a significant increase in learning motivation among students in the experimental group using AR media compared to those in the control group taught through conventional methods, with a significance value of 0.000 < 0.05. These findings indicate that AR provides interactive, concrete, and immersive learning experiences, making it effective in stimulating students’ motivation. This study recommends the integration of AR-based media as an innovative strategy to improve the quality of Science learning in schools..

Abstract

Growing media is one of the key factors influencing the growth of horticultural crops, particularly under controlled environmental conditions. This study aimed to analyze the effects of different growing media compositions on the growth of horticultural plants in a controlled environment. The research employed an experimental method using a completely randomized design, with various growing media compositions as treatments. Growth parameters observed included plant height, number of leaves, and plant biomass. The results showed that differences in growing media composition had a significant effect on all observed growth parameters. Mixed growing media containing soil, organic matter, and porous materials produced better plant growth compared to single-media treatments. The controlled environment played an important role in minimizing external environmental influences, allowing plant responses to growing media to be observed more accurately. It can be concluded that selecting appropriate growing media composition is essential to support optimal growth of horticultural crops and can be applied to efficient and sustainable cultivation systems.
