Mitochondrial metabolism as a potential therapeutic target in myeloid leukaemia
Authors: de Beauchamp Lucie , Himonas Ekaterini , Helgason G. Vignir
Published: September 2021

While the understanding of the genomic aberrations that underpin chronic and acute myeloid leukaemia (CML and AML) has allowed the development of therapies for these diseases, limitations remain. These become apparent when looking at the frequency of treatment resistance leading to disease relapse in leukaemia patients. Key questions regarding the fundamental biology of the leukaemic cells, such as their metabolic dependencies, are still unresolved. Even though a majority of leukaemic cells are killed during initial treatment, persistent leukaemic stem cells (LSCs) and therapy-resistant cells are still not eradicated with current treatments, due to various mechanisms that may contribute to therapy resistance, including cellular metabolic adaptations. In fact, recent studies have shown that LSCs and treatment-resistant cells are dependent on mitochondrial metabolism, hence rendering them sensitive to inhibition of mitochondrial oxidative phosphorylation (OXPHOS). As a result, rewired energy metabolism in leukaemic cells is now considered an attractive therapeutic target and the significance of this process is increasingly being recognised in various haematological malignancies. Therefore, identifying and targeting aberrant metabolism in drug-resistant leukaemic cells is an imperative and a relevant strategy for the development of new therapeutic options in leukaemia. In this review, we present a detailed overview of the most recent studies that present experimental evidence on how leukaemic cells can metabolically rewire, more specifically the importance of OXPHOS in LSCs and treatment-resistant cells, and the current drugs available to target this process. We highlight that uncovering specific energy metabolism dependencies will guide the identification of new and more targeted therapeutic strategies for myeloid leukaemia.

Authors: Ghasemi S. , Khosravi A. , Hashemifard S. A.
Published: September 2021

Rapid population growth and industrial development have led to increasing environmental pollution caused by a variety pollutants such as radionuclides, heavy metals, and pesticides in surface and underground water resources. Magnetic nanoparticles (MNPs) and nanocomposites have received significant attention over recent decades in both fundamental research as well as environmental sciences. The unique characteristics of these materials, such as high physical and chemical stabilities, biocompatibility, low toxicity, easy synthesis, excellent recycling capability, and processability under a magnetic field, make them promising candidates as part of the next-generation technology for the treatment of pollutants. Iron-based nanoparticles (INPs), including magnetite (Fe3O4), maghemite (γ-Fe2O3), hematite (α-Fe2O3), and goethite (α‐FeOOH) have been exploited in environmental applications such as the removal of metalloids, heavy metals, dyes, and organic compounds because of their large surface area to volume ratio, various morphologies, and catalytic properties. In fact, the large iron surface area plays an essential role in the interaction with pollutant contaminants. Unlike the bulk, MNPs exhibit unique magnetism, easily tuned to the desired applications. In this chapter, various properties, different synthesis methods, and characterization of magnetic NPs have been summarized. Finally, the application of the different MNPs have been considered to eliminate and purify hazardous and harmful pollutants from water and wastewater.

Molecular mechanisms of mammalian autophagy
Authors: Trelford Charles B. , Di Guglielmo Gianni M.
Published: September 2021

The ubiquitin-proteasome pathway (UPP) and autophagy play integral roles in cellular homeostasis. As part of their normal life cycle, most proteins undergo ubiquitination for some form of redistribution, localization and/or functional modulation. However, ubiquitination is also important to the UPP and several autophagic processes. The UPP is initiated after specific lysine residues of short-lived, damaged or misfolded proteins are conjugated to ubiquitin, which targets these proteins to proteasomes. Autophagy is the endosomal/lysosomal-dependent degradation of organelles, invading microbes, zymogen granules and macromolecules such as protein, carbohydrates and lipids. Autophagy can be broadly separated into three distinct subtypes termed microautophagy, chaperone-mediated autophagy and macroautophagy. Although autophagy was once thought of as non-selective bulk degradation, advancements in the field have led to the discovery of several selective forms of autophagy. Here, we focus on the mechanisms of primary and selective mammalian autophagy pathways and highlight the current knowledge gaps in these molecular pathways.

Published: September 2021

The difference in the levels of light intensity was responded with changes in morphophysiological and biochemical characters of plants, especially in leaves of black pepper. The aim of this study was to determine the effect of several levels of light intensity on the morphophysiological and biochemical characters of leaves of black pepper. The research was conducted in July - November 2017 in Kemuja, Mendobarat, Bangka Belitung. This study used split-plot design with three replications. The main plots were the levels of light intensity, namely 100%, 75%, and 50%. Subplots were varieties of black pepper, namely Petaling 1, Petaling 2, and Nyelungkup. The results showed that there was no interaction between varieties and light intensities. The morphophysiological and biochemical responses of the leaves of the three varieties tested were the same at all levels of light intensity. Light intensity up to 50% has no effect on leaf morphological characters, but leaves become thinner at lower light intensities. Chlorophyll, nitrate reductase activity and leaf sucrose concentration were same at all light intensities up to 50%. Plants exposed to higher light intensity have a higher number of stomata. The results concluded that the light intensity of up to 50% did not cause changes in leaf morphology and biochemistry and only affected leaf stomata density.

Pontianak tangerine citrus (Siam Pontianak) is the most popular tangerine citrus in Indonesia. Induced mutation with colchicine treatment on Pontianak tangerine was intended to produce polyploid plants. The study aimed to analyze the cytological diversity in colchiploid of Pontianak tangerine citrus. The study was conducted at ICISFRI from January – May 2018. The cytological analysis was performed on a five-year-old of 36 colchiploids of Pontianak tangerine and a mother plant as control. The results showed that the colchiploid plants had higher chromosome numbers, stomatal sizes, and chloroplast numbers than the control. However, the stomatal density in several genotypes did not differ from that of the control. Colchicine treatment resulted in an aneuploid plant with chromosome number 18+x. Based on the clustering analysis results, all colchiploid plants differed from the control with a variability coefficient of 0.65. The colchiploid plants were not grouped according to colchicine concentration and duration of treatment. The increase of colchicine concentration and treatment duration did not correlate with the increasing ploidy number of colchiploid plants. The implication of the research result was the stomatal density, stomatal size, and chloroplast number were useful tools for rapid pre-screening of plant polyploidy.
A promising breeding strategy for tomato resistance to Cucumber Mosaic Virus based on genetic analysis
Authors: Gaswanto Redy , Gunaeni Neni
Published: September 2021

Infection of CMV can reduce tomato yield. One of the controlling methods to solve the problem by using a resistant variety. However, the existence of resistant variety was still not available yet. Therefore, we needed the breeding program for resistance tomato to CMV to obtain a new variety. Information of previous genetic analysis results can be used to determine a promising strategy. Two tomato genotypes namely R8 51-12 as resistant and RG-57 as susceptible accession were crossed reciprocally to obtain F1, F1R, BC1.1, BC1.2, F2. Then, all of the breeding materials were inoculated by strain CMV-2 and observed on symptom disease and virus concentration. Genetic analysis results showed that there was no maternal effect and the resistance controlled by two major genes as recessive, but there was the epistatic effect on disease symptom as a selection parameter. Based on these information, the tomato’s breeding strategy were to use a susceptible genotype as female parent, while a resistant genotype as male parent. Phenotypically disease symptom selection can be conducted in the middle or late generation. However, the selection should be supported by serologically using the Elisa test. The breeding program could be addressed as a F1 hybrid variety.

Beef cattle cultivation is a side job for farmers which is carried out by family labor and the incomes are used to finance various needs of the farmers’ family. This study aims to determine the use of family labor in beef cattle cultivation and the use of livestock sales. The research was carried out from October 2020 to April 2021 in two Women Farmers Groups (WFG) in Bengkulu City and Seluma Regency who received beef cattle assistance from the government. Data were analyzed descriptively. The results showed that in general, beef cattle cultivation was carried out jointly by man and women farmers with a labor allocation of 39.59%. In intensive farming, farmers are more dominant in cultivation activities amounting to 46.25%, while in semi-intensive farming women farmers are more dominant in cultivation activities (41.06%). The income from the sale of livestock are mainly used for children's education expenses and buying vehicles (91.67% each), building or renovating houses (87.50%), and buying feeder cattle (79.17%). For the development of beef cattle in farmer group, it is necessary to consider the cultivation system before determining the target of recipient of the program. The development by WFG is more suitable for semi-intensive cultivation systems.

Farm labour plays significant roles in crops production. This paper aims to describe gender segregation in crops farming, its roles and dynamic during Covid pandemic in West Nusa Tenggara. A survey was conducted in three districts, East Lombok, Sumbawa and Bima, involving 102 farmers. Qualitative and quantitative data were collected using interview method which then analysed descriptively. The results showed that most respondents employed woman labours for planting and mixed labour for harvesting amid the land ownership discrepancy and agroecology conditions. Women were considered to be more skilful and diligent than men. Nevertheless, they received lower pay by 50-100% on daily basis. Covid pandemic situation has posed varying effects on labour prices, work availability and movement. Labour prices generally has increased due to increasing prices of basic needs, yet work availability decreased as land owners tried to reduce cost because of rocketing fertiliser prices. Pandemic situation did not affect labour movement was in East Lombok and Bima since majority farmers used local labour. While in Sumbawa, as many farmers relied on migrant labour from Lombok and Bima for harvesting, the 2020 has affected harvest quality and subsequently selling prices due to late harvest since labours were not allowed to travel.

One of the efforts to accelerate the flow of technological research results to users/farmers is through the development of Agricultural Techno Park (ATP). In this study, the performance evaluation of ATP development using cluster analysis was conducted by applying the Context, Input, Process, and Product (CIPP) model. The aims were to analyze the progress of ATP through clustering techniques and to formulate alternative strategy in the future. This study was conducted using a structured survey approach involving 76 farmers, April to June 2018, at the ATP Cigombong, West Java, Indonesia. The results of distance and similarity analysis showed that aspects of input and process had a closeness of satisfaction. Innovation assistance activities are not optimal, which should lead to becoming independent farmers. The future strategy has formulated context and product indicators in a participatory manner from the beginning, so that the target group understands and detects the progress. Farmers’ needs must be identified from the beginning of ATP development to strengthen self-reliance of supporting facilities. ATP needs to formulate a new method in planning of innovation assistance. It is also important to develop new training (such as motivational training, technical and managerial skills).

This research was carried out to know the status of agricultural technology innovation used by farmers in lowland swamps and formulate policy recommendations for relevant stakeholders in land management for sustainable farming. The study was conducted using a survey method with a structured questionnaire and focus group discussion in 5 villages in Banjar Regency, South Kalimantan, with a total of 48 respondents. The results showed that the main commodity cultivated by farmers in lowlands was rice, where the agricultural technology innovation used was still limited to the use of superior varieties, while the use of other technologies was still low which resulted in low farm productivity. The causes of limited use of agricultural technology innovations include poorly organized land conditions and high-water levels in the land that make it difficult for equipment operations, narrow land area per farmer, limited infrastructure for mobility of agricultural machinery, limited capital, and low educational level of the main actors. Some of the proposed recommendations are improving cultivation technology, especially fertilization according to nutrient status and yield targets, land and water management, using mechanical devices as needed, and increasing the role of related institutions.

The previous research showed that the duku’s peel which dried using infrared radiation could extend the shelf life up to 25 days. The aims of this study to illustrate using 3D visual analysis on microstructural of dried duku’s peel that had dried using infrared radiation. Scanning Electron Microscopy (SEM) technique with magnifications of x100, x500, and x2500, resolution of 10 μm, 50 μm, and 100 μm in dried duku’s peel using infrared radiation at a distance of infrared emitter (IRE) 6 cm and 10 cm with an exposure temperature of 300°C for 60 s. The 3D visual illustration using Mountain Maps Program shows the porosity value on 6 cm distance of IRE, with 300°C of IRE temperature and 60 s of exposure time has 90,91%, while the 10 cm distances of IRE, 300°C of IRE temperature and 60 s of exposure time has 146,95%. It could conclude that from 3D illustrative of SEM by reconstructing a single image into pseudo-color view and a profile curve produced at drying distance of 6 cm, 300°C, and 60 s has lower porosity value, and more stable contour when compared to drying with a distance of 10 cm, 300°C, 6 s, and control treatment. This condition could confirm the previous research. The duku’s peel microtexture condition which was exposed by IRE could create a dry condition as shell-likeness that could maintain the fruit quality and prolong the shelf life.
