<b>Background and Objective:</b> Methotrexate is an anti-metabolic medication used to treat cancer. It causes oxidative stress in nerve tissue and has neurotoxic effects. A strong antioxidant and effective free radical scavenger is vitamin C. The current research aims to investigate the potential protective impact of vitamin C and the toxic consequences of methotrexate. <strong>Materials and Methods:</strong> Thirty-six rats were used in this research and group one (Group 1) got no treatment at all. For 4 weeks, (Group 2) underwent a single intraperitoneal injection of methotrexate at a dose of 20 mg/kg once a week and (Group 3) got methotrexate at the same dosage as Group 2 and vitamin C (20 mg/kg) intragastrically every other day for four weeks. Rats were killed after the experiment and brain hemispheres were removed and prepared for light microscopic analysis. The cerebral hemispheres were ready for biochemical analysis to determine the brain tissue's concentrations of MDA, CAT, GSH and SOD. Data analysis was conducted using SPSS software version 20. <b>Results:</b> In the methotrexate (2)-treated group, there were histological alterations manifested as a reduction in granular layer thickness. Purkinje cells exhibit a reduction in number, a shrinking of the cell bodies and a loss of monolaminar organization. Reduced cellularity was seen in the molecular layer. These cellular alterations are lessened and the thickness of the granular and molecular cell layers is restored following vitamin C treatment. When compared to the MTX+Vitamin C group, vitamin C greatly attenuates the biochemical and histological alterations caused by MTX. <b>Conclusion:</b> Results concluded that although methotrexate is a toxic medication that damages the brain cortex, its toxicity is reduced when vitamin C is taken with it.

<b>Background and Objective:</b> The biodiversity of rice cultivars, including local rice from North Sulawesi, represents a potential source of germplasm for fulfilling national food needs. A few publications related to the characteristics of salinity stress resistance in rice cultivars, including local rice from North Sulawesi. This study aimed to examine the morphological response to salinity stress at the germination phase in eight rice cultivars cultivated in North Sulawesi, Indonesia. <b>Materials and Methods:</b> The randomized block design experiment was conducted in the laboratory using eight rice cultivars (Superwin, Ombong, Temo, Burungan, Ciherang, Inpari 31, Inpago 10 and TB) using the Roll Paper Test method during the germination phase. The treatments in this experiment were salinity stress of 0, 10, 20 and 30% seawater for 14 days. The morphological characteristics evaluated as a response to salinity stress consisted of germination percentage, normal germination percentage, root length, shoot length and root-to-shoot ratio. To determine the significant differences and interactions between treatments (where, p<0.05), the data were analyzed using Analysis of Variance (ANOVA) followed by Least Significant Difference (LSD) 5%. <b>Results:</b> Salinity stress reduced germination rates, including overall and normal germination and shorter shoot and root lengths. However, this stress caused an increase in the root-to-shoot ratio. The Roll Paper Test with salinity treatment at the germination phase could be used as a simple selection method to obtain salinity-tolerant-rice cultivars. <b>Conclusion:</b> Shoot length and root-to-shoot ratio were potential morphological indicators for salinity tolerance in rice.

Methamphetamine (METH) is a highly addictive and dangerous drug that mainly affects neurotransmitters in the brain and leads to feelings of alertness and euphoria. The METH use can lead to addiction, which has become a worldwide problem, resulting in a slew of public health and safety issues. Recent studies showed that chronic METH use can lead to neurotoxicity, neuro-inflammation and oxidative stress which can lead to neuronal injury. This review discussed the history of METH use, the link between METH use and neurotoxicity, the molecular mechanism and the different treatment strategies. This study attempted to discuss some of the drug's principal impacts and gave proof in favor of a few of the cellular and molecular causes of METH neurotoxicity. In addition, it demonstrates the most recent treatment strategies involving mitigating METH-induced neurotoxicity. However, future studies are needed to better understand the mechanism by which METH use induced neurotoxicity.

<b>Background and Objective:</b> Prolonged utilization of chemical fertilizers can harm the soil and disturb the equilibrium of nutrients, resulting in a decline in cherry tomato yield. To enhance the growth of cherry tomato plants, it is necessary to add organic chemicals. The research aimed to determine the best elicitor biosaka concentration to apply to evoke the plant growth of cherry tomatoes (<i>Solanum lycopersicum</i> L. var. <i>cerasiforme</i>). <b>Materials and Methods:</b> This study employed a complete random design with four treatments of biosaka formula: B0 (control, water), B1 (1.5 mL/L), B2 (2.5 mL/L), B3 (3.5 mL/L) and B4 (4.5 mL/L). Twenty-day-old tomato seedlings were transplanted into polybags filled with a compost and husk charcoal mixture. Biosaka application was done every four days by spraying at a 0.5 m distance, starting from the first day after transplanting. Lycopene levels were measured using a UV-vis spectrophotometer at 417 nm after a series of solvent extractions. Data were analyzed using ANOVA for significant effects. <b>Results:</b> The biosaka concentration of 4.5 mL/L gives the highest results for the variables of treatments such as the plant height is up to 167.8 cm, the number of petioles is 62.8 petioles, the number of fruit is 19.6 and the age at flowering is 44.4 days. The biosaka concentration of 4.5 mL/L gave the highest yield for the variable plant height of 167.8 cm, the number of petioles 62.8, the number of fruits per plant 19.6, the initial flowering age of 44.4 days, the wet weight of the plant was 740 g and the dry weight of the plant was 125.1 g. <b>Conclusion:</b> The optimal concentration of biosaka (4.5 mL/L) significantly improved cherry tomato growth and yield, resulting in increased plant height, number of petioles and fruit count. It also accelerated the initial flowering age and enhanced both wet and dry plant weights. This indicates that 4.5 mL/L of biosaka effectively promotes the growth and productivity of cherry tomato plants.

<b>Background and Objective:</b> Turmeric, strawberries and broccoli are popular in the community for their beneficial effects in improving lipid profile, but poor bioavailability and absorption of their phytochemical compounds might reduce their effects while given separately. Therefore, their combination might provide a synergistic enhancement of their property as hypolipidemic agents. This study aims to examine the effects of turmeric, strawberry and broccoli in improving lipid profile in adult patients with hypercholesterolemia. <b>Materials and Methods:</b> Twenty hypercholesterolemic adult patients from Unggul Karsa Medika Hospital in Bandung, Indonesia were recruited for the study, they were given 600 mg/day of turmeric/curcuminoid, 100 g of fresh strawberry and 100 g of boiled broccoli for 30 days. The measurement of the patient's characteristics (body weight, height, BMI) and biochemical parameters in the blood (total cholesterol, triglyceride, LDL-C, HDL-C, SGOT, SGPT, urea and creatinine) were conducted before and after the treatment. <b>Results:</b> The mean age of the patients was 49.15±1.9 years old, with mean height 1.56±0.014 m, weight 61.43±1.96 kg and mean body mass index 25.25±0.87 kg/m^{<a href="86677_op">2</a>}. Lipid profile before the treatment: Total cholesterol 239.75±6.56 mg/dL, LDL-C 172.9±6.53 mg/dL, HDL-C 66.55±3.37 mg/dL and triglyceride 193.7±18.45 mg/dL; after the treatment: Total cholesterol 220.7±9.39 mg/dL, LDL-C 153.95±9.98 mg/dL, HDL-C 59.2±2.45 mg/dL and triglyceride 145±16.55 mg/dL. The result showed a significant reduction of total cholesterol (p = 0.014), LDL-C (p = 0.036), HDL-C (p = 0.001) and triglyceride (p = 0.015) after the treatment. Other biochemical parameters (SGOT, SGPT, urea and creatinine) showed normal levels before and after the treatment. <b>Conclusion:</b> In summary, supplementation of turmeric, strawberry and broccoli improves lipid profile in adult patients with hypercholesterolemia.

<b>Background and Objective:</b> Cervical cancer is the second most common cancer in Indonesia, where traditional herbal treatments like <i>Zanthoxylum acanthopodium</i> (andaliman) are culturally used. Investigating protein biomarkers such as E7, pRb, EGFR and p16 can help assess the efficacy of these treatments. <b>Materials and Methods:</b> There were 5 groups in this study: 2 control groups (C- and C+) and 3 treatment groups (each receiving one of three doses). Oral administration of andaliman was performed for 30 days in cancer model rats, after which the cervix was dissected, cervical tissue was taken and immunohistochemistry repair was performed. Statistical analysis was performed using the Kruskal-Wallis test with a p<0.05. <b>Results:</b> As <i>Zanthoxylum acanthopodium</i> DC dose rose, cervical tissue E7, EGFR and p16 expression decreased. However, greater doses of this plant increased cervical tissue pRb protein. Cervical cancer histology exhibited increased nuclear size, irregular cellular structure, atypical cell shape, higher nuclear-cytoplasmic ratio and various nuclear shape variants. This herb induced tissue to show well-organized non-hyperchromatic cells that resembled normal clusters. <b>Conclusion:</b> <i>Zanthoxylum acanthopodium</i> DC improved cervical tissue and balanced cervical cancer biomarker proteins such E7, EGFR, pRB and p16.

<b>Background and Objective:</b> Betta fish is one of the most popular ornamental fish because of their attractive body shape, especially for males. The fish development usually results in a similar number of males and females or an even higher number of females. This study aimed to determine the effect of various concentrations of honey and the age of larvae on the sex ratio of Betta fish. <b>Materials and Methods:</b> This study was conducted using a completely randomized design with two variables; the concentrations of honey and the ages of Betta fish larvae in 3 replications. There are 45 groups in total with 20 larvae in each group. The levels of honey concentration were 0 (control), 10, 20, 30 and 40 mL/L and the levels of larval ages were 3, 4 and 5 days old. All groups were immersed for 10 hrs in the honey mix and then maintained for 4 months. Sex ratio calculation was performed after 3 months. <b>Results:</b> The both factors have a significant effect on male sex formation. The highest number of males was produced in the honey concentration of 40 mL/L. A significant difference in the number of males was shown in the larval group of ages 3 and 4 days old but not in the groups of 5 days old. <b>Conclusion:</b> Honey treatment and the larval age affect the formation of male Betta fish.

<b>Background and Objective:</b> Todolo coffee (<i>Coffea arabica</i> L. var. typica) is the oldest commercially grown coffee in the Toraja region of South Sulawesi and is currently at risk of extinction. This study aims to induce callus from leaf explants of Todolo arabica coffee and improve the levels of caffeine compounds in Todolo coffee with the additional precursor L-methionine as elicitor. <b>Materials and Methods:</b> This research was conducted at the Tissue Culture Laboratory, Faculty of Mathematics and Natural Sciences, Hasanuddin University. This experimental study used a Complete Randomized Design (CRD) approach. The five stages involved callus induction, elicitation with L-methionine precursor, caffeine extraction, qualitative testing using the Parry Method and quantitative analysis via UV-Vis spectrophotometry. Tools and materials were sterilized using autoclaving and media preparation followed standard procedures with varying L-methionine concentrations. Callus induction from sterilized leaf explants was done under aseptic conditions, followed by L-methionine treatment and caffeine content extraction. Caffeine was analyzed using UV-Vis spectrophotometry at 272 nm and statistical analysis was conducted using ANOVA and DMRT at a 5% significance level. <b>Results:</b> The friable callus structure has a shiny and wavy appearance and is more easily detached, which is highly correlated with the speed of callus growth. The callus on the treatment medium is slightly yellowish-white to somewhat brownish, indicating the production of secondary metabolites. The best concentration of L-methionine treatment was 25 mg/L with a percentage of caffeine content of 0.0078%. <b>Conclusion:</b> Results concluded that the addition of L-methionine has a significant effect on the percentage of caffeine production.

<b>Background and Objective:</b> Non-Suicidal Self-Injury (NSSI) is a mental health threat that is a major concern among adolescents and young adults nowadays. It is assumed that NSSI is involved in the mesocortical dopamine reward system, the endogenous opioid system and the overstimulation of the stress system. This study aims to investigate the correlation between Opioid Receptor Kappa 1 (OPRK1) rs7016778 and rs7824175 gene polymorphisms, Kappa Opioid Receptor (KOR) and Dynorphin level with NSSI. <b>Materials and Methods:</b> This research was a cross-sectional comparative study between 84 subjects diagnosed with NSSI and 76 controls. The method used was purposive sampling. The NSSI was determined by using the NSSID and ISAS questionnaire according to DSM-5. The examination of polymorphism of the OPRK-I gene was examined using a Polymerase Chain Reaction (PCR) and the level of KOR and Dynorphin was determined using ELISA. <b>Results:</b> The OPRK1 rs7016778 gene polymorphism was more common in the NSSI group. The OPRK1 rs7824175 gene polymorphism was more common in the control group. The KOR and Dynorphin levels were higher in the NSSI group. There were differences in KOR levels between NSSI and the control group. There is a relationship between KOR levels and Dynorphin levels with NSSI. There were no differences in the OPRK1 gene polymorphisms rs7016778 and rs7824175 between NSSI subjects and controls. There was no difference in Dynorphin levels between NSSI subjects and controls. <b>Conclusion:</b> The role of the Kappa Opioid Receptor (KOR) and Dynorphin in the pathophysiology of NSSI can be considered.
