The increasing industrial activity in Indonesia, that is not equipped with appropriate waste treatment, has caused an increase of heavy metal contaminants in water bodies. Heavy metals contamination such as copper (Cu), mercury (Hg), cadmium (Cd), and lead (Pb) contamination in water bodies have endangered aquatic life and public health. For this reason, it is urgently important to lower down the concentration of heavy metal pollutants in the water bodies surrounding industrial areas. Compared to chemical remediation, bioremediation of heavy metal by using indigenous bacteria is more effective and economical, since it can be applied in situ directly and be used repeatedly. Acinetobacter sp. IrC2, used in this study, is Indonesian indigenous bacteria isolated from the industrial waste treatment facility in Rungkut, Surabaya. This study aims, firstly, to investigate the heavy metal multiresistance of Acinetobacter sp. IrC2 against mercury, cadmium, and lead. Secondly, this study intends to examine its bioaccumulation capacity for single and heavy metal alloys. The heavy metal multiresistance test was carried out by measuring the minimum heavy metal concentrations that inhibit bacterial growth (Minimum Inhibitory Concentration/MIC). The bioaccumulation capacity was measured using an atomic absorption spectrophotometer (AAS). Â It is shown that Acinetobacter sp. IrC2 has high multiresistance to mercury, cadmium, and lead with MIC values of 12 mM, 8 mM, and 18 mM, respectively. Furthermore, Â it is also resistant to Â heavy metal mixture of 4.5 mM. Â The mechanism of bacterial resistance in response to heavy metal toxicity, in general, is by accumulating heavy metals in the cells. The highest amount of accumulated heavy metals identified, from bacteria grown in the medium contains a mixture of heavy metals, were 0.023 mg, 0.084 mg, 0.684 mg, and 1.476 mg per gram of cell dry weight for copper, mercury, cadmium and lead respectively. Â In conclusion, Acinetobacter sp. IrC2 is a promising heavy metal bioremediation agent due to its heavy metal multiresistance and accumulator characteristics.Â Â Key words: Acinetobacter sp.

The genetic diversity of typical clinical isolated Plasmodium falciparum in the malaria population varies greatly, especially at the location where malaria disease were recorded at high incidence rate. MSP2 is known as glycoprotein expressed on the surface of merozoites, which is an antigenic protein and has a potential to act as vaccine candidate for malaria. The MSP2 gene has two main allelic groups called FC27 and 3D7/IC. Block 3 from MSP2 gene is the most polymorphic to describe the diversity of parasite populations. The P. falciparum parasite population is often characterized by wide genetic diversity in areas of high transmission intensity. Therefore, the study on P. falciparum diversity is useful to describe the level of malaria transmission. The study of genetic diversity focused on clinical isolated species at Wamena General Hospital was aimed to determine the presence of the MSP2 gene, variety of MSP2 gene alleleÂ and the dominant frequency of the MSP2 gene allele. This research has been carried out from March 2018 to February 2019 using a cross sectional approach. The research sample was taken and prepared from Wamena Regional Hospital and followed by the analyzing of DNA isolation, PCR, electrophoresis of the research samples was done at the genetic science laboratory in Jakarta, Indonesia. The samples studied were patients who met the inclusion criteria, namely a single P. falciparum infection with an asexual parasite density >1000 parasites/Âµl or >3+ (1-10 P/Lp), and were agreed to become respondents by signing an informed consent. A total of 26 clinical isolates of P. falciparum were isolated with the MSP2 gene distribution on the FC27 allele with the highest as many as 25 samples (96.2%), 22 samples (84.6%) of the 3D7 / IC allele while the mixture of the two alleles was 22 samples (84.6%). From a total of 26 samples, there were samples with the male gender category counted for 77.3% and female 41%. The results of the identification of clinical isolated P. falciparum at Wamena Hospital with a total of 26 samples were found in productive age, between 15-34 years with a single allele (95.8%), while 23 cases and mix (both alleles 87.5%) about 21 cases, meanwhile in cases of before-productive age, in which ages were 12 and 14 years of age with a single allele 100% (FC27) 2 cases and 50% (3D7/IC) found to be 1 case, The mixture of the two alleles is 50% was only 1 case and there was no sample at non-productive age observed.Â Key words: Malaria; MSP-2; P. falciparum; Wamena

Red tilapia is a one of the economically important fish species. In order to increase growth and feed efficiency, feed restriction strategies can be carried out. This study aims to determine the effect of periodic (weekly) restriction of feed on compensatory growth and physiological responses of red tilapia during the enlargement phase. The activity was carried out at the Fish Breeding Research Center for 4 months. The research method used a completely randomized design (CRD) 4 treatments with 3 replications, namely control (fish were fed daily), 1 (1 fasting day a week), 2 (2 fasting days a week), and 3 (3 fasting days a week). Fish rearing was conducted on the concrete tub measuring 2 x 1 x 0.8 m3 with a stocking density of 10 fish m-2. During the maintenance period of 120 days the fish were fed satiation twice a day. The results showed significant differences (P <0.05) in the value of weight growth, specific growth rate, daily growth and feed conversion ratio between control and other treatments, but not significantly different from treatment S1. The highest survival value was indicated by S1 treatment. The blood faal values of fish that were given feed restrictions consisting of red blood cells, white blood cells, hematocrit and hemoglobin showed that there was not significantly different than control fish (P> 0.05), which was at normal values. Restriction of feed to 1 day a week showed partial compensatory growth with better feed efficiency than fish fed daily.

Published: March 2021

Fisheries management or conservation requires information on length-weight relationship (LWR) for the fishing regulation and biomass estimation. This study aims to assess LWR estimation using two methods, regular and Bayesian hierarchical approached for big-eye Scad (Selar crumenophthalmus). Samples of big eye Scad were collected at several fish landings around Ambon Island from March to August 2020. Length-weight relationship measurement to obtain the parameters of W = a*Lb was tested using generalized linear model and t-test. The parameter b for monthly sampling was not significantly different (F = 0.77, df = 70, P = 0.89) and showed isometric growth b=3 (t = -1.13, df = 4, P = 0.32). Regular measurement resulted parameter log10(a) = -1.99 (±SD = 1.06) dan b = 3.06 (±SD = 0.084). Bayesian method produced parameter log10(a) = -2.07 (±SD = 0.2365) dan parameter b = 3.21 (±SD = 0.1497). Weight measurement from HB approach was significantly higher than the regular method (t = 1.65; df = 405; P <0.0001), and might produce over-estimated of weight from length data. Discrepancy of these methods was overcome by combining all information of LWR to obtain the best estimation on LWR parameters.

<img src=” https://s3.amazonaws.com/production.scholastica/article/21978/large/graphical_abstract300.jpg?1616953934”> With the advancement of technologies, the evolution of nanoscience is occurring at a rapid pace. The demand for nanomaterials in various industries has increased. However, they may pose an increased risk upon exposure to living organisms, demanding toxicological studies. Alt-hough risk assessment of nanomaterials is a challenge due to their varieties in sizes and variabil-ity in properties, different methodologies of toxicity screenings have been used successfully to evaluate the potential risks. Although nanotechnology has contributed to technology develop-ment and well-being, information in these fields is still incomplete. Fortunately, those areas are under continuous research, and there are increasing experimental efforts in determining the envi-ronmental effects on humans exposed to nanoparticles. Since the field of nanotechnology is continuously expanding, we need medium- to high throughput nanotoxicity screenings to deter-mine any potential risks caused by nanomaterials. Zebrafish, a well-established model for mammalian research, have advantages when used in these toxicity screenings. This review de-scribes various kinds of toxicities induced in zebrafish embryos by different kinds of nanopar-ticles. A significant number of experimental data from toxicological studies are also presented that determine nanomaterials’ effects, which can be modulated or further mitigated to create a positive impact on living organisms.

AbstractAlthough significant improvements have been made in the outcomes of children with cancer, the pace of improvement has slowed in recent years as the limits of therapy intensification may have been reached for many pediatric cancers. Furthermore, with increasing numbers of pediatric cancer survivors, the long‐term side effects of treatment have become increasingly apparent. Therefore, attention has shifted to the use of molecularly targeted agents and immunotherapies to improve the outcomes of children who are not cured by traditional cytotoxic chemotherapies and to decrease exposure to cytotoxic chemotherapy and reduce late effects. This review describes the recent progress in the treatment of children with cancer, focusing in particular on diseases in which targeted and immunotherapeutic agents have made an impact.
