Abstract
Isothermal constant strain rate compression tests on Mg-1Nd-1Mn-2Zn magnesium alloys were performed using the Gleeble-1500 thermal simulation testing system at 200-350 °C and 0.001-1 s-1. The Arrhenius model was used to create the constitutive equation model. According to the processing diagram of magnesium alloy in the dynamic material model, the findings demonstrate that the peak stress increases with increasing strain rate and decreases with increasing deformation temperature. The constitutive equation model is constructed with excellent precision using the Arrhenius model, the average relative error is 4.21, and the correlation coefficient is 98 %. According to the analysis of the processing diagram, the optimum processing parameters of Mg-1Nd-1Mn-2Zn magnesium alloy are 300 °C and 0.001 s-1.

Abstract
The populations of Notopterus notopterus or commonly known as Javan Belida, in some places are rarely found and their populations have decreased. Domestication is one strategy of fisheries resources management related to the rare condition, threatened extinction, or even disappearance of fish species. Domestication is also part of the initiative for developing the aquaculture effort of this species. The purpose of this study is to assess the adaptation of N. notopterus on gonad maturation in several rearing systems as a base of the initial domestication. Fish were collected from the Rawa Pening reservoir in Central Java, Indonesia. Gonad maturation assessment was carried out on different rearing system, namely semi-ground pond, square concrete pond, three units of the oval concrete pond and square concrete pond with closed recirculation system. As a comparison, another group of fish also reared in their natural habitat using cage system. Results showed that the maturity level of female fish is the highest in an oval tube, while the lowest was in a semi-ground pond. The square concrete pond is a potential container for gonadal maturation processes since it produces from low to high levels of gonad maturity and produces the largest value of high-level gonad maturation.

Abstract
A study on the cultivation of Porphyra spp. has been carried out in the waters of Ambon Island. This plant is in great favor with local communities but has not been able to meet broader demands. The purpose of this research was to look into the future of mass culture. In the splashing zone, which is about 10 m above sea level, samples of gametophyte foliose or thalli were taken. The thallus was brought to the laboratory and maintained in a 100-liter container. During the rearing period, the thallus released spermatia and fertilized carpogonia. Carpogonia develop into carposporangia and release zygotospores outside the thallus. A small zygotospore develops into a large carpospore. Carpospores are the forerunners of new sporophytes if they find the correct substrate. In the laboratory, the nacre layer of pearl oyster shells was used to replace the natural substrates. Carpospores attached to the nacre layer germinated and grew into conchocelis. The conchocelis then develops the conchosporangia outward, followed by the release of the conchospores. Conchospores are a source of new thalli grown on polyethylene nylon nets. Conchospores that grew into new thalli on nylon nets were then moved to their natural environments so they could keep growing.

Abstract
Traditional dried anchovy processing from the Kei archipelago is very simple that is only through the process of drying by spreading the fish on the net or tarpaulins on the side of the road under direct sunlight. The purpose of this study was to profile the traditional dried anchovy product from Selayar Village, Southeast Maluku, including processors, businesses, and constraints faced. This study used a descriptive method to describe the profile of dried anchovy, processing, business, and constraints faced. The business profile is done through questionnaires and interviews. Data were processed using Microsoft Office Excel. The quality of dry anchovy products was considered good with the advantages of protein and mineral content. The dry anchovy production business from Selayar village is a home industry business and is an ancestral heritage and involves processors who graduated from Elementary School and High School. Marketing at the producer level is classified smoothly and conducted in the village by consumers, especially collecting merchants. Processing was done in the catch season without special treatment that is only by drying the fish with the sun so it takes a long time and very much depends on the weather.

Abstract
Morotai Island Regency is located in North Maluku Province which 89% of villages in the district are located in coastal areas which are rich in marine resource potentials. Fish is a food that is easily damaged so it is necessary to handle to maintain its quality. Fish processing also needs to be done to anticipate the abundance of catches. The problem that occurs in Titigogoli Village is the lack of fishermen’s knowledge about fish handling, as well as the lack of fish processing knowledge (fishermen’s wife) to produce the good quality products. This study aims to determine the quality of fish caught by Titigogoli Village fishermen and it’s handling method, and provide alternative businesess. This study was conducted in June - August 2022. The analysis was pH analysis and organoleptic test to see the quality of fish and SWOT analysis to formulate a strategy for developing business of fishery product. The results showed that the quality of fish was included in the fresh category with an average pH value and organoleptic were ranging from 6.20-6.43 and 7.27-9.00, respectively. The recommended alternative business is smoked fish because it quite potential. Strategy formulation for the development of fisheries businesses for fishermen/business actors in Titigogoli Village is (a) increasing the independence of fishermen/business actors through support the facilities and training in processing quality products; (b) increasing village cooperation with related agencies; (c) Improving fisheries business management; (d) Development of infrastructure to accommodate fishermen’s catch.

Abstract
In this study, liquid smoke production waste gas (LSPW) was used as a substitute for carbon monoxide (CO) and filter smoke in handling frozen tuna steaks. Tuna steaks were packed in plastic bags, then inside the bag, tuna steak were sprayed with CO and LSPW, and stored at 4°C for two days. After that, each package was vacuumed and stored at -25°C for four weeks. Observation of quality deterioration of tuna steak started from the beginning of storage until the fourth week. The results showed a significant difference in the average TPC value of tuna steak sprayed with CO and LSPW during frozen storage. While the values of pH, TVB, myoglobin, and color were not significantly different. Until the end of the observation, the quality of tuna steak was still relatively good with myoglobin content values of CO and LSPW treatments, respectively: 36.65±4.78 and 42.04±4.47 mg%, color 34.67±9.07 and 35.67±8.50 °Hue, pH 6.47±0.15 and 6.60±0.10, TVB-N 18.04±0.93 and 17.86±0.98 mg N/100g, histamine 1.92±0.05 and 1.85±0.13 ppm, and TPC 7.41x102 and 8.70x102cfu/g.

Abstract
Shrimp fisheries are one of the targets for local governments in designing and developing a marine protected area, especially in East Aceh Regency. In general, one of the efforts to preserve shrimp production requires information on larval distribution. The larval phase in the shrimp life cycle is essential for continuing stock production in nature. This study aims to analyse the distribution of shrimp larvae which become potential resources. This study was conducted at ten stations in the coastal area in April and September 2015. The data collected used a “bongo net” with a mesh size of 500 mm with a mouth opening of 60 cm and a length of 3 metres which was pulled flat at a speed of ± 2 knots for 10 minutes. Faund, the highest shrimp larvae abundance, was the family Palaemonidae. At the same time, the lowest was the family Sergestidae. In addition, found two families (Squillidae and Penaidae) were besides these, other shrimp species were grouped in the unidentified category. To conduct further research, such as analysis of habitat utilisation and degradation status that can affect shrimp stocks, risk assessment and evaluation, and support factors, as input in determining the conservation area of shrimp resources.

Published: July 2023

Abstract
The local knowledge system puts the cultural capacity, knowledge system, religious value, tradition, and social capital as important in managing natural resources. The local community of Ilili Village has used the local wisdom, locally called sasi and siritaun in coastal resources management. The coastal natural resources managed through this local wisdom are sea cucumber, top shell, green turban, and fish. The objective of this study was to identify factors that affect the status of local wisdom implemented in the effectiveness of fish resource sustainability. The study was conducted from April to June 2022, and a purposive sampling method was used for respondent selection. FGD and interviews were used to collect the data. The Rapid appraisal of fisheries (Rapfish) was used to assess the local wisdom status, and the DPSIR conceptual model framework was used to propose the strategy for sustainable management of sasi and siritaun (local wisdom). The Analytic Hierarchy Process (AHP) was used to propose a priority strategy from a multicriteria strategy objective. The study shows that the local wisdom was generally fair sustained with ecology sustained while institutional was less sustained. There were seven strategies proposed for sustainable management at the first level criteria and three additional strategies at the second level. The combined strategy proposed following its ranking were the implementation of local wisdom, the establishment of village regulation, and the increase in the local community income.

Abstract
Mangroves can store carbon. However, it also produces carbon emissions by degrading organic matter in mangrove sediments. This research was conducted in a mangrove ecosystem at Waiheru, in the inner Ambon bay, to determine CO2 and CH4 emissions and their potential for global warming (GWP) from mangrove sediments. Gas is taken through a syringe mounted on the hood. Gas concentration analysis used the gas chromatography method, while the average gas concentration in each sediment was tested using ANOVA Single Factor. The results showed that the average concentration of CO2 gas was significantly different for each sediment (P-value <0.05), while the average concentration of CH4 gas was not significantly different (P-value >0.05). The largest CO2 gas emission in mangrove sediments in Waiheru Village was found in sandy mud sediments with an emission value of 136.99 mg.m−2.h−1, and the lowest was in sand sediments, namely 13.01 mg.m−2.h−1. Meanwhile, the largest emission of CH4 gas was in silty sand sediments, namely 0.32 mg.m−2.h−1, and the lowest was in sandy mud sediments, namely 0.15 mg.m−2.h−1. Fluctuations in carbon gas emissions in each sediment are inversely proportional, which indicates that the formation of CH4 gas is obtained through ethanol reduction, which utilizes CO2 gas concentrations. The total GWP in the mangrove sediments of Waiheru Village is 231.58 mg.m−2.h−1. The GWP contributed by the type of sandy silt sediment was 140.72 CO2-eq mg.m−2.h−1, muddy sand was 70.95 mg.m−2.h−1, and sand sediment was 19.91 CO2-eq mg.m−2. h−1.

Abstract
Although phytoplankton of the Banda Sea has been studied since 1970s, its information is still limited. In order to provide a better understanding of phytoplankton diversity, during the Expedition of Jala Citra 2 Banda 2022, phytoplankton sampling was done in the surface waters at five stations in the northern Banda Sea. The purpose of this study was to analyze the abundance and species composition of phytoplankton during the southeast monsoon season. Phytoplankton samples were taken at different mixing layers, kept them into sample bottle and were identify in the laboratory of Deep Sea Research Centre BRIN Ambon. Chemical and physical parameters were measured simultaneously. A total of 64 species of phytoplankton were found and they composed of diatom which the most diversified group with 48 species, followed by dinoflagellate with 16 species. Among diatoms, most dominant species were contributed by Thalassionema nitzschiodes (3640-1,266,573 cell/m3) and Thalassionema fraunfeldii (2800-288,570 cell/m3) followed by Chaetoceros sp and Skeletonema costatum. These dominant species composition were different from previous reports. Most of these species were found in a chain. For the dinoflagellates Ceratium longipes (280-5,231 cell/m3) dan Ceratium vulvur (280-1.960 cell/m3) were identified as the dominant species. The cell count of total phytoplankton varied from 280-1,266,573 cell/m3. Spesies diversity index was calculated using Shannon’s formula (H’) and dominance index (D) range from 1.089-2.552 and 0.117-0.418, respectively. Water temperature, salinity, pH and dissolved oxygen ranged from 26.7-29.5°C, 33-34 ppt, 7.85-8.14, and 5.57-7.03 mg/l, respectively.

Published: July 2023

Abstract
A facile, simple, green and sensitive spectrofluorometric method was developed for determination of the calcimimetic drug cinacalcet hydrochloride. It is used for the treatment of hyperparathyroidism. The drug showed high native fluorescence intensity at 320 nm after excitation at 280 nm. The method was linear over the range of 5.0–400.0 ng ml−1 with excellent correlation (R2 = 0.9999). Limit of detection (LOD) and limit of quantitation (LOQ) values were 1.19 and 3.62 ng ml−1, respectively. The percentage recovery was found to be 100.42% ± 1.39 (n=8). The proposed method was successfully applied for determination of cinacalcet in spiked human plasma samples with % recoveries of (87.23 to 109.69%). Two recent greenness metrics (GAPI and Analytical Eco-Scale) were chosen to prove the eco-friendly nature of the method. Furthermore, the proposed method was successfully applied to dissolution study of commercial cinacalcet tablets. The interference likely to be introduced by some commonly co-administrated drugs such as metoprolol and itraconazole was studied; the tolerance limits were calculated.
Development of a scoring system to identify high-yield specimens for bacterial broad-range 16S rRNA gene PCR with sequencing at a tertiary care medical center
Authors: Dumm Rebekah E , Glaser Laurel J , Rodino Kyle G 
Published: July 2023

Abstract

Objectives
Broad-range bacterial polymerase chain reaction with sequencing (BRBPS) provides valuable diagnostic data, especially in cases of culture-negative infections. However, as BRBPS testing demonstrates generally low positivity, cost per impactful result can be high and commonly involves longer turnaround times compared with other methods, targeting use of this assay to high-yield situations remains a challenging goal. Diagnostic stewardship can help alleviate these challenges and increase clinical utility, yet not all laboratories have a dedicated stewardship team, and little formal guidance exists on identifying high-yield samples outside of specific clinical syndromes. In this study, we performed a retrospective review of 86 BRBPS orders from a tertiary care medical center, with a focus on identifying high-yield cases using an infectious markers scoring system, visualized inflammation or organism (VIO) score, to predict return of actionable diagnostic data.

Methods
Using chart review, we evaluated how results from high VIO score or low VIO score specimens contributed to clinical management.

Results
Testing low VIO score samples identified an organism in only 10% of samples, and of these positive results, 33% were considered to represent contamination. Despite negative routine workup and no identified pathogen via BRBPS, broad antimicrobial treatment was continued in 85% of cases with a low VIO score. In contrast, specimens with high VIO scores were more predictably positive by BRBPS, identified organisms that were universally considered pathogens, and provided opportunities to target or de-escalate antimicrobial therapy.

Conclusions
This study describes the VIO scoring system to guide the identification of high-yield samples and steward the appropriate use of BRBPS testing.

Abstract

Objectives
SRSF2 mutations are known to be associated with poor outcomes in myelodysplastic neoplasm, but studies on their prognostic impact on acute myeloid leukemia (AML) remain limited. In this retrospective study, we analyzed clinical and pathologic characteristics of patients with AML and correlated the outcomes with SRSF2 mutations.

Methods
We characterized the morphologic, immunophenotypic, molecular, and clinical findings in AML with mutated SRSF2 and compared them with SRSF2 wild-type (WT) myeloid neoplasms (MNs).

Results
Using next-generation sequencing, we identified 134 patients with MNs and SRSF2 mutations (85 with AML and 49 with MNs) in addition to 342 SRSF2-WT AMLs. Fifty-two (62%) patients with altered SRSF2 demonstrated a variable degree of morphologic dysplasia. The most frequent immunophenotypic aberrancies in SRSF2-mutant AML included diminished CD33 expression and overexpression of CD7, CD56, or CD123, similar to WT AML. More IDH1/2 (P = .015) and NPM1 (P = .002) mutations were seen in SRSF2-mutant AML than in SRSF2-mutant non-AML. Further, more IDH1/2, ASXL1, RUNX1, and STAG2 mutations were observed in SRSF2-mutant AML than in SRSF2-WT AML (P &lt; .0001 to P = .001). Finally, patients with SRSF2-mutant AML showed a significantly worse overall survival (OS) than patients with SRSF2-WT AML (P &lt; .0001), but this worse OS appeared to be rescued by allogeneic stem cell transplant (allo-SCT).

Conclusions
Acute myeloid leukemia with altered SRSF2 shows a variable degree of morphologic dysplasia without uniform immunophenotypic aberrancies. SRSF2 mutations appear to be independent poor prognostic factors, but allo-SCT has improved the clinical outcomes in patients with SRSF2-mutant AML.

Abstract

BACKGROUND
The prognostic utility of NT-proBNP in the setting of hypertension has not been well-characterized in the general US adult population.

METHODS
We measured NT-proBNP in stored blood samples collected from participants 1 year or older who participated in the 1999–2004 National Health and Nutrition Examination Survey. In adults 20 years or older without a history of cardiovascular disease, we assessed the prevalence of elevated NT-pro-BNP by blood pressure (BP) treatment and control categories. We examined the extent to which NT-proBNP identifies participants at higher risk for mortality across BP treatment and control categories.

RESULTS
Among US adults without CVD, the prevalence of elevated NT-proBNP (≥125 pg/ml) was 27.2% among those with untreated hypertension, 24.9% among those with treated controlled hypertension, and 43.3% among those with treated uncontrolled hypertension. Over a median follow-up of 17.3 years and after adjusting for demographic and clinical risk factors, US adults with treated controlled hypertension and elevated NT-proBNP had increased risk of all-cause mortality (HR 2.29, 95% CI 1.79, 2.95) and cardiovascular mortality (HR 3.83, 95% CI 2.34, 6.29), compared to adults without hypertension and with low levels of NT-proBNP (&lt;125 pg/ml). Across all levels of SBP and irrespective of antihypertensive medication use, elevated NT-proBNP was associated with an increased risk of mortality, compared to low levels of NT-proBNP.

CONCLUSIONS
Among a general population of adults free of CVD, NT-proBNP can provide additional prognostic information within and across categories of BP. Measurement of NT-proBNP may have potential for clinical use to optimize hypertension treatment.
