The Effectiveness of Newborn Care Promotion on Increasing Knowledge, Attitude, and Breastfeeding Practice among Mothers in North Jakarta

Background: Breastfeeding is one of the most important contributors to the health, growth and development of the newborns. This study aimed to determine the effect of the promotion of newborn care by health cadres on increasing knowledge, attitude, and practice of breastfeeding among mothers. Subjects and Method: This study was quasi-experimental design with one group preposttest in 2020. The population in this study were mothers who had newborns in Koja, Cilincing, and Tanjung Priok sub-districts, North Jakarta. A total of 50 mothers were selected. The dependent variables were knowledge, attitude, and practice. The independent variable was promotion of newborn care. Data was collected by questionnaire. Data were analyzed using paired-t test and Mc Nemar test. Results: The mean score of breastfeeding knowledge was higher after intervention (Mean= 16.10; SD=1.11) than before intervention (Mean= 13.34; SD= 1.14) and it was statistically significant (p < 0.001). The mean score of breastfeeding attitude was higher after intervention (Mean= 15.38; SD= 1.25) than before intervention (Mean= 15.38; SD= 0.83) and it was statistically significant (p<0.001). Mothers were more likely to practice breastfeeding after participation in the promotion of the newborn care (OR= 2.00; 95% CI= 1.22 to 3.33; p= 0.008). Conclusion: Promotion of newborn care by health cadres improves knowledge, attitude, and practice of breastfeeding.
Factors Predicting Training Delays and Attrition of Recruits during Basic Military Training

Ensuring a balance between training demands and recovery during basic military training (BMT) is necessary for avoiding maladaptive training responses (e.g., illness or injury). These can lead to delays in training completion and to training attrition. Previously identified predictors of injury and attrition during BMT include demographic and performance data, which are typically collected at a single time point. The aim of this study was to determine individual risk factors for injury and training delays from a suite of measures collected across BMT. A total of 46 male and female recruits undertaking the 12-week Australian Army BMT course consented to this study. Injury, illness, attrition, and demographic data were collected across BMT. Objective measures included salivary cortisol and testosterone, step counts, cardiorespiratory fitness, and muscular endurance. Perceptions of well-being, recovery, workload, fatigue, and sleep were assessed with questionnaires. Baseline and mean scores across BMT were evaluated as predictors of injury and attrition using generalized linear regressions, while repeated-measures ANOVA was used for the group comparisons. From the 46 recruits, 36 recruits completed BMT on time; 10 were delayed in completion or discharged. Multiple risk factors for injury during BMT included higher subjective ratings of training load, fatigue, and stress, lower sleep quality, and higher cortisol concentrations. Higher ratings of depression, anxiety, and stress, and more injuries were associated with a higher risk of delayed completion. Higher concentrations of testosterone and higher levels of fitness upon entry to BMT were associated with reduced risk of injury and delayed completion of BMT. Ongoing monitoring with a suite of easily administered measures may have utility in forewarning risk of training maladaptation in recruits and may complement strategies to address previously identified demographic and performance-based risk factors to mitigate injury, training delays, and attrition.
Effects of Late Pleistocene Climatic Fluctuations on the Phylogeographic and Demographic History of Japanese Scad (Decapterus maruadsi)

The Late Pleistocene-Holocene climate fluctuations have greatly influenced the phylogeographic structure and historical dynamics of many marine organisms in the western Pacific marginal seas. Here, we investigated the impact of Pleistocene glacial-interglacial cycles on the phylogeographic structure and demographic dynamics of Decapterus maruadsi, an economically important fish along the coast of the East China Sea (ECS) and northern South China Sea (NSCS). We obtained 430 concatenated sequences (Cyt b + control region, 1548–1554 bp) of D. maruadsi, including 246 newly sampled from the ECS and 184 previously determined from the NSCS. Genetic structure and phylogenetic analysis demonstrated a lack of significant population structure among 16 populations. Moreover, there was no significant differentiation among populations from Chinese coastal waters and northern Vietnam. Neutrality tests, unimodal mismatch distributions, Bayesian skyline plots, and the star-like haplotype networks all indicated a recent demographic expansion for D. maruadsi population during the Late Pleistocene-Holocene, explaining the low genetic diversity in D. maruadsi along the southeast coast of China. Notably, phylogenetic analyses and net genetic distances based on Cyt b jointly confirmed that 57 Cyt b haplotypes identified as D. maruadsi from the previously defined Sundaland-Rosario-Ranong clade actually represented D. russelli. These results not only reveal the complex effects of Pleistocene-Holocene climate fluctuations on the phylogeographic structure and demographic history of D. maruadsi but also provide useful genetic information for the management of genetic resources.

Abstract. Fatimah, Suroiyah F, Solikha N, Rahayuningtyas ND, Surtiningsih T, Nurhariyati T, Ni’matuzahroh, Affandi M, Geraldi A, Thontowi A. 2022. Antimicrobial activity of actinomycetes isolated from mangrove soil in Tuban, Indonesia. Biodiversitas 23: 2957-2965. This study aims to isolate, identify, and investigate the antimicrobial activity of actinomycetes isolated from mangrove soil of the Mangrove Center Tuban in Jenu Village, Tuban District, Indonesia. Soil sampling was carried out with a purposive sampling technique. The dry-heating and pour plate methods were used to isolate actinomycetes. Four isolates (LIB.2; LIA.4; LIA.9; and LIA.10) were selected and tested for their antimicrobial activities against Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, and Candida albicans ATCC 10231 using disc diffusion method. Colony morphology characterization and Gram staining were then conducted on the 4 isolates. The identification of LIB.2 was performed by biochemical assay and 16S rRNA gene sequence analysis. The results showed that crude antimicrobial extracts (CACs) of all isolates inhibited the growth of E. coli but not S. aureus and C. albicans. Isolate LIB.2 showed the highest inhibition zone with a diameter of 15,65 ± 2,33 mm, followed by LIA.9 (10,19 ± 2,78 mm), LIA.4 (9,80 ± 0,47), and LIA.10 (8,75 ± 0,42 mm). The most potential isolate was identified as a member of Streptomyces genera. Based on biochemical assay and 16S rRNA gene sequence analysis, LIB.2 was identified as Streptomyces vellosus strain LIB.2.

A New Hybrid Metaheuristic Algorithm for Wind Farm Micrositing

This work focuses on proposing a new algorithm, referred as HMA (Hybrid Metaheuristic Algorithm) for the solution of the WTO (Wind Turbine Optimization) problem. It is well documented that turbines located behind one another face a power loss due to the obstruction of the wind due to wake loss. It is required to reduce this wake loss by the effective placement of turbines using a new HMA. This HMA is derived from the two basic algorithms i.e. DEA (Differential Evolution Algorithm) and the FA (Firefly Algorithm). The function of optimization is undertaken on the N.O. Jensen model. The blending of DEA and FA into HMA are discussed and the new algorithm HMA is implemented maximize power and minimize the cost in a WTO problem. The results by HMA have been compared with GA (Genetic Algorithm) used in some previous studies. The successfully calculated total power produced and cost per unit turbine for a wind farm by using HMA and its comparison with past approaches using single algorithms have shown that there is a significant advantage of using the HMA as compared to the use of single algorithms. The first time implementation of a new algorithm by blending two single algorithms is a significant step towards learning the behavior of algorithms and their added advantages by using them together.
The Optimization of Dietary Protein Level and Carbon Sources on Biofloc Nutritive Values, Bacterial Abundance, and Growth Performances of Whiteleg Shrimp (Litopenaeus vannamei) Juveniles

A biofloc technology-based 75-day indoor growth trial in an 80 L glass aquaria was conducted to evaluate the effects of two different carbon sources (sugarcane bagasse, SB, and wheat flour, WF) on the biofloc composition, bacterial abundance, and growth of whiteleg shrimp (Litopenaeus vannamei) juveniles (0.23 ± 0.04 g). Three different levels of dietary protein content (250, 300, and 350 g protein kg−1 diet) and two carbon sources (SB and WF) were applied (SB250, WF250, SB300, WF300, SB350, and WF350, respectively), comparing to a controlled diet without biofloc and fed on a 450 g protein kg−1 diet (C450). With the addition of SB and WF, water quality was in the ideal recommended ranges for L. vannamei culture. At the end of the experiment, the biofloc volume increased with increasing dietary protein levels. The nutritional value of biofloc in different treatments was influenced by dietary protein and added SB and WF. Increasing dietary protein significantly increased the protein and lipid contents of the produced biofloc. The use of WF as a carbon source significantly increased lipids and nitrogen-free extract in the biofloc. The total heterotrophic bacterial (THB) count was significantly higher (p < 0.05) in WF300 and WF350 than in the other treatments. The mean effect of the protein levels and carbon source was significantly reported, whereas the highest significant THB count was recorded with 300 dietary protein and using WF as a carbon source. The growth performances of L. vannamei fed with biofloc treatments were significantly (p < 0.05) higher than the C450 group. The highest final weight and weight gain were recorded in SB350 treatment. The feed conversion ratio was not affected by reducing dietary protein levels; meanwhile, the protein efficiency ratio increased significantly in biofloc treatments than in the control. Overall, the results demonstrate that, compared to the control treatment of 450 dietary protein, the biofloc treatments using WF as a carbon source could compensate for the reduction in the dietary protein levels in the diet of L. vannamei and maintain higher zootechnical performance.
The Effect of Elevated Alanine Transaminase on Non-invasive Prenatal Screening Failures

Objective To determine the effects of alanine transaminase (ALT) levels on the screening failure rates or “no calls” due to low fetal fraction (FF) to obtain a result in non-invasive prenatal screening (NIPS). Methods NIPS by sequencing and liver enzyme measurements were performed in 7,910 pregnancies at 12–26 weeks of gestation. Univariate and multivariable regression models were used to evaluate the significant predictors of screening failure rates among maternal characteristics and relevant laboratory parameters. Results Of the 7,910 pregnancies that met the inclusion criteria, 134 (1.69%) had “no calls. ” Multiple logistic regression analysis demonstrated that increased body mass index, ALT, prealbumin, albumin levels, and in vitro fertilization (IVF) conception rates were independently associated with screening failures. The test failure rate was higher (4.34 vs. 1.41%; P < 0.001) in IVF pregnancies relative to those with spontaneous conceptions. Meanwhile, the screening failure rates increased with increasing ALT levels from 1.05% at ≤10 U/L to 3.73% at >40 U/L. In particular, IVF pregnancies with an ALT level of >40 U/L had a higher test failure rate (9.52%). Compared with that for an ALT level of ≤10 U/L, the adjusted odds ratio of “no calls” for ALT levels of 10–20, 21–40, and >40 U/L was 1.204 [95% confidence interval (CI), 0.709–2.045], 1.529 (95% CI, 0.865–2.702), and 2.764 (95% CI, 1.500–5.093) (Ptrend < 0.001), respectively. Conclusions Increased ALT and IVF conceptions were associated with a higher screening failure rates in NIPS. Therefore, a feasible strategy to adjust these factors to reduce the probability of “no calls” due to low FF would be of great clinical significance.
Occurrence of common core structure and genotype-specific signatures among the Vibrio of environmentally diverse vended crabs and shrimps from selected Lagos seafood markets, Nigeria

Abstract. Odeniyi OA, Olawuyi OJ, Ogunsanya O, Unuofin JO. 2022. Occurrence of common core structure and genotype-specific signatures among the Vibrio of environmentally diverse vended crabs and shrimps from selected Lagos seafood markets, Nigeria. Biodiversitas 23: 3081-3090. This study investigated the occurrence of Vibrio species from the gastrointestinal tract of vended crabs and shrimps using Multiplex polymerase chain reactions (Multiplex PCR) method. Different primer pairs were used to detect the presence of hsp, sodB, SodB-R, ctx, toxR, and Vchol virulent genes in the samples. The phylogenetic relationships among the Vibrio species were determined and the polymorphic information content of selected Vibrio primer products was generated using Powermarker V3.25 Dendo-UPGMA program based on Jaccard’s coefficient. The detection of Vibrio virulence genes confirmed the presence of Vibrio species in the DNA extracts of 19 out of the 60 crustacean samples. Among the Vibrio species, Vibrio parahaemolyticus was the most frequently identified species (47.4%), followed by Vibrio cholerae (36.8%), and Vibrio mimicus (15.8%), while the presence of Vibrio vulnificus was not detected in the crab and shrimp samples. Phylogenetically, the Vp.tdh primer constituted the highest allele number, gene diversity and polymorphic information content of 18.00, 0.9444 and 0.9415, respectively, while the mean of the Vp.tdh and Vp.trh primer sequence combination was polymorphic (0.7153). Among the 19 positive Vibrio strains, different major clusters and subclusters were identified, indicating the relatedness between the identified species. The result of this study indicates that the innocuously vended crab and shrimp samples are indeed reservoirs of pathogenic Vibrio species whose consumption by humans might affect the health of the general populace.
A checklist of cephalopods from continental shelf of Sarawak, Malaysian Borneo

Abstract. Morni WZW, Hassan R, Abit LY, Latif K. 2022. A checklist of cephalopods from continental shelf of Sarawak, Malaysian Borneo. Biodiversitas 23: 3203-3208. Cephalopods can be discovered in all the oceans of the world ranging from shallow to deep oceans. It is a naturally inhabited seawater medium and indirectly limits the number of research regarding the species composition of the cephalopods group. Previously, samples of cephalopods were collected from selected stations in Sarawak Exclusive Economic Zone (EEZ) using an otter trawl net with a stretch mesh size of 38 mm at the cod end. All samples used in this study were the by-catch of trawling activities during National Demersal Fish Resource Survey in Sarawak (16 August until 6 October 2015). Trawling operations were conducted beyond 12 nautical miles from the coast, and the area was divided into three depth strata, I) 20-50 m; II) 50-100 m; and III) 100-200 m. In total, 16 species of cephalopods were found to inhabit Sarawak waters, representing five families and eight genera. The present findings found that there was a higher number of species recorded in-depth strata I (14 species) in comparison to strata II (12 species) and III (11 species). Six species of the cephalopods captured in this study were the first recorded in Malaysian water, namely Amphioctopus marginatus, Amphioctopus rex, Ommastrephes bartramii, Sepia brevimana, Sepia vietnamica and Sepia prashadi. Thus, the information on cephalopod diversity and distribution at different depth strata will be useful for updating the current database on Malaysian marine species diversity.
Exploring the Impact of TREM2 in Tumor-Associated Macrophages

Simple Summary TREM2+ macrophages were recently reported to be highly enriched and associated with immunosuppression in various cancer types. Hence, TREM2 targeting represents a new promising approach for cancer treatment that is based on reprogramming of tumor-associated macrophages to reshape anti-tumor immunity and overcome resistance to current therapies. Abstract Tumor-associated macrophages (TAMs) represent a key component of the tumor microenvironment and are generally associated with immunosuppression and poor prognosis. TREM2 is a transmembrane receptor of the immunoglobulin superfamily expressed in myeloid cells. TREM2 has been extensively studied in microglia and neurodegenerative diseases and recently emerged as a marker of pro-tumorigenic macrophages. The accumulation of TREM2-expressing TAMs was reported across numerous cancer patients and tumor models. TREM2 genetic blockade or TREM2 targeting with antibodies resulted in improved tumor control, enhanced response to anti-PD1, and significant changes in the tumor immune landscape. Preclinical studies paved the way for an ongoing clinical trial with a TREM2 depleting antibody and inspired further exploration of TREM2 targeting therapies. Here, we review the current knowledge about the impact of TREM2 in cancer, with an emphasis on the TREM2+ macrophage signature across different cancer types, the contribution of TREM2 to TAM phenotype and function, and the promising effects of TREM2 modulation.
Entanglement Between Two Mechanical Oscillators in a Dual-Coupling Optomechanical System

In this study, we investigated the properties of entanglement of an optomechanical system including two mechanical oscillators, where two mechanical oscillators are coupled with the cavity field in different coupling modes: the interaction between one mechanical oscillator and cavity field is first-order coupling, and the interaction between the other and the cavity field is quadratic coupling. On the one hand, the entanglement between two mechanical oscillators is studied. The influence of the frequency of the cavity field, the mass of mechanical oscillators, and the temperature of mechanical oscillators on the entanglement between two mechanical oscillators are investigated. On the other hand, for the given parameters of the system, we also obtained the entanglement between the cavity field and the mechanical oscillator that has a quadratic coupling. Compared with the entanglement between microscopic particles, the stable macroscopic quantum entanglement between two mechanical oscillators has the characteristics of long existence life and can be reused, and it also plays an important role in quantum information processing and quantum network construction.
Morpho-physiological responses of iaa9 tomato mutants to different levels of PEG simulated drought stress

Abstract. Suminar E, Budiarto R, Nuraini A, Mubarok S, Ezura H. 2022. Morpho-physiologicalresponsesof iaa9 tomato mutants to different levels of PEG simulated drought stress. Biodiversitas 23: 3115-3126.This study aimed to analyze the morphological and physiological responses of iaa9 mutants and its WT-MT to different levels of drought stress in in vitro growing medium. This study applied a completely randomized design with two factors, i.e., tomato genotypes and polyethylene glycol (PEG) - induced drought stress levels. The factor of varieties consisted of three levels, i.e., WT-MT as control (G1), iaa9-3(G2), and iaa9-5 (G3). The factor of PEG-induced drought stress also consisted of four levels, i.e., 0% PEG as control (PEG0), 5% PEG (PEG5), 10% PEG (PEG10), and 15% PEG (PEG15). The results observed 12 weeks after culture showed the variations of the morpho-physiological response of WT-MT and mutant genotypes to PEG-induced in vitro drought stress. The WT-MT showed a higher reduction in plantlet height, root number, and root length than mutants under severe drought conditions. The plantlet fresh and dry weight of iaa9-3and iaa9-5were higher than its WT-MT under no drought conditions. The total chlorophyll content of WT-MT was lower than iaa9-5due to the significant gain of chlorophyll-b on that mutant rather than its WT-MT. However, the analysis of principal components and correlation revealed the reduction of morphological size and leaf pigment content in response to drought stress, irrespective of genotype factor. These results suggest that in vitro selection techniques using PEG is useful for the initial screening of drought-tolerant tomato.
Exploring L2 Engagement: A Large-Scale Survey of Secondary School Students

Engagement, a psychological individual difference variable with three facets (vigour, dedication and absorption), has recently attracted scholarly attention. Through a large-scale survey, we examined what we call ‘L2 engagement’ among 21,370 secondary school students in China, with an L2 engagement scale adapted from the Utrecht Work Engagement Scale (UWES)-student version. Factor analysis showed this scale to be empirically unidimensional with three highly intercorrelated facets and very high internal consistency; this contributes to our understanding of the conceptual challenges surrounding the construct of engagement (e.g., dimensionality) and the broader issue concerning the correspondence between empirical constructs and theoretical terms (e.g., engagement in our case). Hierarchical regression revealed that the selected sociobiographical variables (e.g., L2 proficiency) were linked to L2 engagement to varying degrees; adopting a more refined approach to gauge the unique contribution of a predictor to L2 engagement in hierarchical regression, we identified L2 proficiency, parental attention, study time and frequency of parental coaching as (very) important predictors for L2 engagement. We call for more studies to adopt our L2 engagement scale, a sufficiently valid and reliable instrument developed based on a large sample. We also propose a few future research directions (e.g., combining self-reports with other data sources).
