<![CDATA[The last few decades have seen an increase in the number of elderly populations around the world. One consequence of an aging population is an increased incidence of impaired cognitive function. Serotonin, or 5-hydroxytryptamine (5-HT), is found to be involved in many physiological or pathophysiological processes including cognitive function. Alterations in serotonin (5-HT) function have been hypothesized to underlie a range of physiological, emotional, and cognitive changes in eldery. This paper provide reviews and references that a serotonin plays a role in the cognitive function of the elderly.]]>

<![CDATA[Meatballs are one of the processed meat products that are in great demand by all levels of society. Along with the times and changes in public consumption trends, currently meatballs are turning into frozen food which is more simple and practical for cooking anytime. As processed frozen meat, making frozen food meatballs are often added with food additives (BTP) to maintain food quality such as preservatives, thickeners, and dyes. Borax is a dangerous chemical that is often added to food as a thickening agent. This study aims to determine and compare frozen food meatballs sold in modern markets and traditional markets in Palembang City which contain borax based on physical tests and to analyze borax levels using UV-Vis spectrophotometry. In this study, the maximum wavelength obtained to measure the absorbance of the 10 samples that have been prepared is 423,50 nm. Determination of the standard borax solution curve that has been made with various concentrations were 5 ppm, 10 ppm, 20 ppm, and 30 ppm. The obtained linear equation y = 0,0352x + 0,2047 with coefficient correlation (r) 0,9631. The levels of borax contained in the frozen food meatballs as the research samples were sample A contained 13,322 µg/ml, sample B contained 9,392 µg/ml, sample C contained 12,688 µg/ml, sample D contained 23,379 µg/ml, sample E contained 29,127 µg /ml, sample F was 24,821 µg/ml, sample G was 17,583 µg/ml, sample H was 15,595 µg/ml, the sample I was 26,665 µg/ml, sample J was 12,460 µg/ml. Based on physical tests, the characteristics of frozen food meatballs containing borax showed a brighter color, an unnatural smell, very chewy, and hard texture that is difficult to destroy. In conclusion, the ten samples of frozen food meatballs tested all contained borax with varying levels.]]>

<![CDATA[Obesity is defined as excessive fat accumulation that presents as risk factor for various chronic diseases such as diabetes, cardiovascular disease, hypertension, hyperlipidemia, and cancer. The number of obese population has reached 1 trillion people worldwide and is expected to increase at 42% of the world population until 2030. Excess calories in obesity increase the formation of Reactive Oxygen Species (ROS) that cause DNA damage. DNA damage results in inhibition of the cell cycle and lead to cellular senescence. The mechanism of cell senescence caused by cell cycle inhibition can occur through the cellular senescence pathway by p53/p21 WAF1/CIP1 and p16INK4A / pRB. White adipose tissue is an appropriate reservoir to study of cellular senescence. White adipose tissue of obese model mice showed that there was cellular senescence with marked increase in p21 and p16 gene expression in obese mice]]>

<![CDATA[One of the potential agricultural products from Pasinan Village, Lekok sub-district, Pasuruan, East Java Province is Kawista Fruit. Residents of Pasinan used kawista fruit for consumption, both raw and ripe. The large consumption of this kawista fruit leaves an abundance of fruit peels. Based on the results of phytochemical analysis, the extract of kawista fruit peel contains saponins, tannins, alkaloids, flavonoids, and terpenoids. Another income source of Pasinan residents comes from marine resources, that can be served in fresh fish, dried fish and other processed fish is susceptible to contaminated by microorganisms such as Salmonella sp. Salmonella sp. is pathogenic microbe lives on intestines of animals and humans. This study aims to determine the antibacterial activity of kawista rind extract on the growth of Salmonella sp. in-vitro and to determine the concentration of Kawista rind extract which is effective for inhibiting the growth of Salmonella sp using the paper disc diffusion method. The results of this study, the diameter of the inhibitory zone for the growth of Salmonella sp. using variables concentrations of kawista rind extract at 12.5%;25%;50%;75%;100%, with negative control of aquadest and methanol and positive control is tetracycline. At a concentration of 100% Kawista extract, the diameter of the bacterial inhibition test was the largest and significantly different from another treatment group at concentrations of 12.5%;25%;50%;75%. However, the 100% Kawista extract showed a smaller inhibitory zone than the tetracycline treatment group, but not significantly different. In methanol treatment, the inhibition test showed that the diameter of the bacteria was greater than Kawista extract treatment group of 12.5%;25%;50%;75% but not significantly different. Based on the results of the study, it can be concluded that kawista rind extract is effective for inhibiting the growth of Salmonella sp. bacteria, Kawista rind extract at a concentration of 100% is most effective for inhibiting the growth of Salmonella sp bacteria and shows results that are not significantly different from tetracycline]]>

<![CDATA[The high use of methamphetamine (MA) has resulted in many cases of overdose leading to death, where bodies are generally found after several days which complicates the investigation so that a forensic entomotoxicological analysis using insects is carried out. The use of necrophagous insects was chosen because necrophagous insects such as maggots were at the crime scene. Maggot was then analyzed using Gas Chromatography-Mass Spectrometry (GCMS) with several stages. The preliminary test was carried out using the marquis reagent which changed the color of the sample to orange if positive for methamphetamine, then continued with TLC (Thin Layer Chromatography) analysis and obtained the Rf value close to the comparative Rf value, which means that maggot positively contains methamphetamine. Maggot was extracted by maceration and sonication methods using methanol:chloroform 1:3 solvent. Finally, a confirmatory test was carried out using a GCMS and it was found that methamphetamine had a retention time of 3.554 minutes and a peak of 58.1. The results are matched with NIST (National Institute of Standards and Technology) library data. It can be concluded that the use of maggot in analyzing methamphetamine using GCMS can be realized properly]]>

<![CDATA[Extracts from the leaves of the kemuning plant have bioactive compounds that have potential as antibacterial. However, there are some difficulties when using bioactive compounds such as instability, reactivity and having a strong odor. To overcome this problem, it is important to carry out the treatment, namely, the microencapsulation technique. Microencapsulation is a technique for coating the active ingredient with a polymer that can protect the active component thereby increasing the bioavailability of the active compound to be covered by the coating material. The polymer materials used as coating materials in this study were chitosan and STTP using the ionic gelation method. The characteristics measured included the phytochemical test, PSA test, antibacterial, FTIR, and SEM. Phytochemical test results showed the presence of alkaloids, flavonoids, PSA test showed micro-sized encapsulation, antibacterial indicated the presence of a strong inhibitory zone which had potential as antibacterial, FTIR indicated the presence of OH, C=O, NH groups. Keywords: Microencapsulation, Antibacterial, Kemuning Leaf Extract, Ionic Gelation.]]>
