Abstract

Memory formation in mammals involves complex stages, from initial learning to long-term storage. This review highlights key memory-related genes and proteins such as SYNGAP1, Arc/Arg3.1, BDNF, FOXP2, COMT, NR3C1, KIBRA, H-Ras, ERK1/2, and other genes. Mammals serve as important models in memory research due to their evolutionary proximity to humans, providing insights into brain structures such as the hippocampus and prefrontal cortex, which are crucial in memory processes. Molecular mechanisms such as transcription, translation, synaptic plasticity, long-term potentiation (LTP), and long-term depression (LTD), as well as neurotransmitters like glutamate, GABA, acetylcholine, dopamine, and serotonin, are comprehensively discussed with a focus on small, large mammals, and humans. Neurotransmitters affect various functions, including emotion, cognition, memory, learning, and motor functions in test animals. Disruptions in neurotransmitter homeostasis have been linked to numerous neurological and neurodegenerative disorders, highlighting the need to understand the complex mechanisms behind memory in mammals. A brief overview of genes and neurotransmitters related to memory and learning will provide insights and considerations in basic neurobiology and biomedical research.

Abstract

In Indonesia, bone marrow transplantation is a treatment which not known yet to some people. Kariadi Hospital is the one hospital that do it first. On 1987, it was successful for acute myeloid leukemia case. Bone marrow transplantation is one of therapy used to treat patients with leukemia, severe aplastic anemia, Hodgkin's disease, non-Hodgkin's lymphoma, myeloma multiple, many blood disorder and solid tumor. This study described the patients characteristics who did hematopoietic stem cell transplantation during 2017-2021 at Kariadi General Hospital Semarang. This study is a quantitative research non-experiment with design retrospective analysis. Data was taken with a total sampling are 20 patients. Data analysis by describing the criteria. The results describe the sex of patients consist are 60% male and 40% female. Most range age at 35-44 years amount 30%. The diagnosis is 40% in the case of Myeloma Multiple. Most of transplantation doing an autologous transplant are 80%. It is indicated 90% of malignancy cases. All patient got 100% engraftment, all patients happen neutropenia, thrombocytopenia, oral mucositis, gut disorder, and electrolyte imbalance. Amount 15% are hematuria and 10% are urticaria, Veno Occlusive Disease, sepsis, brain infection and brain hemorrhage. The conclusion is patients who did hematopoietic stem cell transplantation have various adverse events and complications depending on many factors or comorbids. These are age, sex, diagnosis, stage of disease, state of remission, regiment conditioning. Health professionals should upgrade knowledge and skill for treatment of hematopoietic stem cell transplantation.

Abstract

Polyurethane is a class of polymers characterized by their substantial tensile strength and high melting points which enables them to be extremely durable. Despite its xenobiotic origin, polyure-thane has been found susceptible to biodegradation by microorgan-isms. The main object of this research was to investigate polyurethane degradation by the bacterium isolated from decayed teak wood (Tec-tona grandis Linn. f.). Polyurethane degrading bacteria were isolated using selective medium in the form of LB (Luria Bertani) with the ad-dition of 0.3% Impranil. Bacterial biodegradation activities shown by the changes of polyurethane structure analyzed by FT-IR spectrosco-py. The bacterial identification was carried out based on observations on the morphological characteristics of the colonies, cell morphology and sequences of 16S rRNA encoding genes. One of the potential iso-late that successfully isolated was K9, which demonstrates the disap-pearance of the 1735/cm peak of the characteristic function urethane in the FT-IR analysis. Analysis of the 16S rRNA encoding gene showed that the potential isolate having 98% similarity index to Bacillus safen-sis strain FO-36b. The activity shown by the isolate suggests that the bacteria could be a promising agent for polyurethane degradation.

Abstract

Among various edaphoclimatic factors influencing coffee bean quality, altitude is one of the primary factors that should be taken into account. This study aims to explore the relationship between altitude, morphological traits, and biochemical composition of robusta coffee in Temanggung Regency, the largest coffee-producing area in Central Java Province, Indonesia. Research sites were purposively selected and categorized into two altitude groups: GS, PS, and GN, located at circa 600 m a.s.l., and GT, WO, and TG, located at circa 900 m a.s.l. A total of 15 morphological traits were observed, consisting of eight vegetative and seven generative traits. Caffeine content was measured following the AOAC procedure using UV-Vis spectrophotometry, while brew acidity was evaluated using a pH meter. Several morphological traits of Temanggung robusta coffee demonstrated significant relationships with altitude. Canopy and stem diameter showed negative correlations with altitude, with correlation coefficients of -0.366 and  -0.408, respectively. Conversely, fruit width               (r = 0.041), bean length (r = 0.049), and bean thickness (r = 0.047) exhibited positive correlations. Regarding biochemical composition, caffeine content stood out by displaying a strong positive correlation with altitude (r = 0.816). Additionally, several morphological traits, including the number of primary branches, the number of productive branches, the number of fruits per bunch, and traits related to fruits and beans, appear to be advantageous for selection and breeding programs. Understanding these relationships provides valuable insights for developing superior Temanggung robusta coffee plants adapted to specific altitudinal conditions.

Abstract

Indonesia is home to 1,248 species of freshwater fish, which play a vital role in sustaining the ecosystem. Lakes Ranu Pani, Ranu Regulo, and Ranu Darungan, located within the Bromo Tengger Semeru National Park, lack data on freshwater fish. This study aimed to assess fish diversity in these lakes using environmental DNA (eDNA) metabarcoding and to establish phylogenetic relationships among the species present. Water samples were filtered using 0.45 µm mixed cellulose ester filter paper, after which the collected DNA was extracted utilizing a DNA miniprep kit. The 12S rRNA gene was amplified using the MiFish primer, and the amplicon DNA was sequenced with the Illumina MiSeq 2x250 platform. The sequences were aligned using Blast+ for species identification and subsequently analyzed for alpha and beta diversity. A phylogenetic tree was constructed with MEGA12. The findings revealed eight species from five families, with Gambusia affinis being the most abundant. Ranu Pani exhibited low species diversity, while Ranu Regulo and Ranu Darungan displayed moderate diversity. Beta diversity analysis indicated similarities between Ranu Pani and Ranu Regulo, but distinct communities were found in Ranu Darungan. Phylogenetic analysis showed close relationships between species from the Cichlidae and Osphronemidae families, while a more distant relationship was observed with the Cyprinidae family. These baseline data can serve as a reference for future research on developing conservation strategies, monitoring environmental changes, and supporting biodiversity management.

Abstract

Indole acetic acid (IAA) is an auxin hormone that can regulate plant growth and development. Bacteria produce IAA through L-tryptophan metabolism. The purpose of this study was to determine the ability of endophytic bacteria isolated from Daun Dewa plants to produce IAA to increase the germination and growth of tomato seedlings. Isolation of endophytic bacteria was carried out by sterilizing plant surfaces. The production of IAA is done by adding L-tryptophan precursors. The results showed that there were six endophytic bacteria, and three isolates of them have the potential to produce IAA, namely: AD1.1, UD1.1, and UD2.1. The highest IAA concentration was produced by isolate AD1.1. Growth in sprouts is significantly influenced by the concentration of IAA; the higher the concentration of IAA, the longer the shoots and the roots. Based on the 16S rRNA gene sequence, these isolates belong to the genus Klebsiella.
