Diabetes mellitus (DM) is a serious health problem in Indonesia. Type 2 diabetes is a metabolic disease which primarily caused by obesity-linked insulin resistance. There is a link between insulin resistance and bacterial populations in the gut. Therefore, the aims of this study was to analyze composition of bacteria belong to the phylum Firmicutes and Bacteroidetes in women with type 2 diabetes and non-diabetic persons as control. The study included five female adults type 2 diabetes patients and five healthy controls. The bacteria composition was analyzed for abundance by denaturing gradient gel electrophoresis (DGGE). Metagenomic analysis based on 16S rRNA gene was represented by 12 DGGE bands. The twelve respective bands showed the similarity ranging from 77 up to 98%. Diversity of microbial composition in women type 2 diabetes was represented by five DGGE bands are Bacteroides fragilis, Bacteroides vulgatus, uncultured Bacteroides sp. clone Lb4eF4, uncultured bacterium clone 16sms90-5g05, and uncultured bacterium clone Malaga 1F14. Four DGGE bands in women healthy controls are closely related to uncultured bacterium isolate DGGE gel band Eub42, uncultured bacterium isolate DGGE gel band K115, uncultured bacterium clone HFV04255, and Enterococcus sp. the finding shows bacterial species belong to the phylum Bacteroidetes was mostly found in women diabetic group, while those belong to the phylum Firmicutes was mostly found in healthy controls.

This study is intended to examine the growing phases and the harvest of sugarcane crops. The growing phases is analyzed with remote sensing approaches. The remote sensing data employed is Landsat 8. The vegetation indices of Normalized Difference Vegetation Index (NDVI) and Enhanced Normalized Difference Vegetation Index (ENDVI) are employed to analyze the growing phases and the harvest of sugarcane crops. Field survey was conducted in March and August 2017. The research results shows that March is the peak of the third phase (Stem elonging phase or grand growth phase), the period from May to July is the fourth phase (maturing or ripening phase), and the period from August to October is the peak of harvest. In January, the sugarcane crops begin to grow and some sugarcane crops enter the third phase again. The research results also found the sugarcane plants that do not grow well near the oil and gas field. This condition is estimated due as the impact of hydrocarbon microseepage. The benefit of this research is to identify the sugarcane growth cycle and harvest. Having knowing this, it will be easier to plan the seed development and crops transport.

Cynomolgus macaques (Macaca fascicularis) are an established animal model of asthma, which exhibit different responses to allergen exposure that are clinically relevant. The chemokine ligand gene (CCL7) encodes Monocyte Chemotactic Protein-3, which has an important role in asthma pathogenesis. While CCL7 polymorphism in humans is associated with asthma phenotype, very little is known about CCL7 in nonhuman primate models of respiratory disease. The objective of this study was to isolate and characterize CCL7 gene in cynomolgus macaques of Indonesian origin. In this study, we used sequencing and bioinformatics technique for gene isolation, characterization, and protein 3D structure prediction. We isolated a 2253 base-pair (bp) sequence of CCL7 in cynomolgus macaques, which exhibited 95% similarity in coding sequence to human CCL7. The amino acid sequence was more closely clustered with human CCL7 than with that of rodents. Importantly, the predictive protein structure of CCL7 was similar to that in humans. These similarities in CCL7 suggests the potential of cynomolgus macaque as a translational model to study asthma, particularly in the context of genetics and role of chemokines such as CCL7.

Jatropha curcas (J. curcas) is usually monoecious plants, which have male and female flowers on the same inflorescence. However, J. curcas can be found as an androgynomonoecious plant (have male, female, and hermaphrodite flowers), even though very rare. Androgynomonoecious J. curcas can be identified after six months of planting when it had started flowering. Therefore, it is important to identify the characteristics of androgynomonoecious J. curcas that can differentiate between androgynomonoecious and monoecious plants in earlier stages of growth. The objectives of the research were to observe isozymes, chromosome and flowers gender of androgynomonoecious and monoecious J. curcas Banten and Lampung accessions. Seeds from five genotypes of J. curcas were used in the research. The observation was carried out on the chromosome and isozymes (Peroxidase and Esterase isozymes) could be used as markers to differentiate androgynomonoecious and monoecious plants. Observations about the flower gender from offsprings derived from different seeds were important to know the inheritance of flower gender. The androgynomonoecious and monoecious J. curcas were diploid with number of chromosomes 2n=2x=22. The chromosomes of androgynomonoecious have longer than that of monoecious J. curcas. The isozymes of androgynomonoecious J. curcas had four alleles and monoecious J. curcas (Banten female monoecious) had three alleles. The flower inflorescence and gender derived from androgynomonoecious plants were unstable, due to androgynomonoecious is intermediate state.

This study aims to obtain the physiological value of dugongs that live in natural habitats (in-situ) as protected wildlife, namely on the coast of Lingayan Island, Toli-Toli Regency. Wild dugongs caught on the beach were put into a net cage. After 14 days of living in a beach cage, measurements of heart rate, respiration, and body temperature were measured using non-invasive methods. This study showed that the value of heart rate, respiration, and body temperature were measured (80.00±17.32) beats/minutes, (17.33±6.80) inspiration/minute, and (32.75±0.07)°C. This physiological value is higher when compared to dugongs that live in captivity, this is likely due to the process of homeostasis through physiological adaptation mechanisms. The physiological value of the dugong is very important for the advancement of dugong animal health science and technology. Besides this finding can be a medical reference that is very useful for veterinarians in the diagnostic and therapeutic process.
