Published: December 2022

The population of feeder cattle in feedlots is not significant compared to the total cattle population. However, the intensive management system in feedlots has negative impact on the environment. Currently, there is limited information on manure handling in the beef cattle feedlots in Indonesia. This study aimed to describe the manure management system of surveyed feedlots in Lampung Province, Indonesia. The method of this study was descriptive with field observation and survey in three feedlots in Lampung. Data related to manure management were collected on the farm, while the data on manure management systems, animal characteristics, and housing system were gathered from questionnaires in the survey. The data were described and analysed using comparison with previous studies. The result showed that the surveyed feedlots utilize manure as organic fertilizer. The manure and effluent were treated and pumped onto forage fields. One feedlot company with an advanced manure treatment facility has implemented a sustainable manure management strategy. The study suggests further research to measure the carbon cycle for several types of feedlot’s manure management systems as an environmental product declares of beef cattle production in Indonesia.

The Best Management Practices (BMP) could improve oil palm production in smallholder plantations. This study aims to identify the effect of BMP and farmers’ practice (REF) on bulk density (BD), total N, available P, and organic C. The research was conducted in the smallholder oil palm plantations in Jambi Province, Indonesia. BMP applied pruned fronds stacks in inter-rows and within rows with fertilizer application above it except nitrogen fertilizer applied in the weeded circle. Besides, REF practice applied prune fronds stacks in inter-rows with all type of fertilizer application in the weeded circle. The result based on transect analysis showed that organic C, total N, and available P significantly higher near oil palm trees. In contrast, BD did not show a significantly different. Comparing BMP and REF practice revealed that BD, organic C, and total N did not differ significantly in all point observations. However, available P showed significantly different in point 2, 4, and 6. As this study was conducted in the second year of BMP treatment, the soil properties of BD, organic C, and total N were not influenced by BMP treatment. BMP study give land management information to improve soil properties that support oil palm production.

Published: December 2022

The fall armyworm Spodoptera frugiperda (FAW) is an alien invasive species that attacked maize crops in Indonesia in 2019. This pest is reported to cause significant damage, so control measures are required. Understanding farmers’ perceptions, knowledge, and management of FAW are important steps towards developing sustainable integrated management strategies as farmers are important actors in this context. A total of 102 farmers were selected for interviews from Bandung, Garut, and Sumedang districts. We found that most respondents surveyed were of productive ages, and the majority were male. Most farmers in all districts were able to differentiate FAW based on distinguishing morphological features and level of damage on infested maize plants. Farmers consider a significant yield reduction if the pest is not controlled. However, due to limited information, most farmers relied on chemical insecticides to control this pest. Farmers in Sumedang, nevertheless, also practiced mechanical and cultural methods for FAW management. In addition, extension agents and farmer groups can help improve farmers’ knowledge of the fall armyworm related to control measures applied to manage FAW. Therefore, enhancing farmers’ capacity through participation in training courses and farmer groups, as well as extension agents’ role as information sources about FAW should be increased.

Published: December 2022

Zinc oxide nanoparticles (ZnONPs) incorporated cellulose acetate bio-polymer (CA) sustainable nanofiber (NFs) seed coating material was produced by electrospinning technique. Varying concentrations (12wt% to 17wt%) of CA as binder and 100mg/L of Zinc oxide nanoparticle (ZnONPs) as an active ingredient were used to produce electrospun nanofiber seed coating. FESEM, water contact angle (WCA), and membrane porosity analysis were performed to determine the physical properties of the CA/ZnONPs NFs. The germination capacity (%) of the aerobic paddy seed cv. MRIA was used to examine the effect of treated coated seeds. Results indicate that CA-ZnONPs of 17wt% CA with 100mg/L of ZnONPs produced beads-free homogenous morphological fiber with a nanometric scale of 526±139nm. 17wt% of CA-ZnONPs electrospun nanofiber results in high porosity by 94% and increases hydrophobicity to 131±2.0° compared to (CA NFs) respectively. The highest germination percentage was obtained from coated seed with 17wt% of CA with 100mg/L of ZnONPs with 60% and 67%, respectively, at 3 and 7 days after incubation. It was enhanced by about 45% and 33% (3 days), 20.8% and 29.8% (7 days) as compared to CA NFs and control. Higher germination capacity is essential to paddy cultivation as it is a physiological element that contributes to producing good in growth performance and quality of rice yield.

Published: December 2022

The extraction process in herbal plants maintains the quality of herb extracts by reducing the water content to prevent the growth of microorganisms and minimize the alteration of metabolites in plants. In this study, we investigate the effect of drying methods and incubation temperature on the flavonoid content of Phyllanthus niruri. Herb samples were fresh, oven-dried, and air-dried. Air-dried sample produced the highest total flavonoid level compared to other drying methods incubating at -20 degrees Celcius and 27-30 degrees Celcius. Air-dried samples incubated at room temperature had the highest total flavonoid content compared to other methods, followed by oven-dried and fresh samples. Fresh samples produced the highest yield compared to other drying methods on incubation at room temperature and -20 degrees Celcius. Various drying methods show a similar result of total flavonoids on incubation at -20 degrees Celsius, despite air-dried samples having the highest flavonoid content. Incubation temperatures have no significant difference in yield and flavonoid content, but the drying method shows otherwise. There is no interaction between the drying method and incubation temperature. Air-dried and oven-dried samples incubated at room temperature produce higher yield and flavonoid content than those incubated at -20 degrees Celcius, having a similar pattern.

Published: December 2022

The Green Economy concept is an important component of Indonesia’s economic development plan. This concept is a comprehensive approach to reflect the interdependence between the economy and the ecosystem, taking into account the negative impact of economic activities on the environment from a sustainable development point of view. The trust growth program seeks to create a conducive environment for investment and capital raising, which is carried out with the government to build investors, attract capital, and create sustainable ‘green’ business models that can generate profits, as well as open up new untapped opportunities. The purpose of this study was to determine the importance of the role of budgeting in realizing a green economy and economic growth. This study uses library/literature research. An important step towards realizing green growth for Indonesia is to establish a convention for a vision of what Indonesia wants to achieve by 2050 – a vision linked to a comprehensive green growth strategy. Achieving this vision requires taking advantage of current and future green growth opportunities strategies. The obligation to carry out budgeting, if any, must also be carried out at the regional level.

Published: December 2022

Our previous study found five genes consist of Insulin-like growth factor-1 (IGF-1), Growth hormone (GH1), Growth hormone receptor (GHR), Myostatin (MSTN), and Leptin (LEP) are responsible for the economic traits of Madura Cattle. This paper aimed to identify the protein-to-protein interaction of genes responsible for the economic traits of Madura Cattle. In silico study was done using STRING v.11.5 with Bos taurus IGF1, GH1, GHR, MSTN, and LEP as input analysis. Results show 24 biological processes, 3 molecular functions, and 6 KEGG pathways as potential protein interactions between genes. All genes are involved in six biological processes i.e. response to the hormone, response to oxygen-containing compound, cell surface receptor signalling pathway, regulation of signal transduction, positive regulation of the cellular metabolic process, and positive regulation of the macromolecule metabolic process. Five genes were predicted as functional partner genes, namely Leptin receptor (LEPR), Tyrosine-protein kinase receptor (INSR), Activin receptor type-2b precursor (ACVR2B), Insulin-like growth factor 1 receptor (IGF1R), and Insulin-like growth factor-binding protein 3 (IGFBP3). Based on the results, we can demonstrate the protein-to-protein interaction of IGF-1, GH, GHR, MSTN, and LEP genes which are potentially related to each other. Further experimental study is required to validate the interaction.

In addition to the problem of water availability and quality, the Citratum watershed is also experiencing problems with soil erosion and sedimentation. Climate change and land use cover are the leading causes of this. Therefore, monitoring water conditions and soil erosion is prioritized in the central Citarum watershed covering an area of 227,020 hectares. The purpose of this study was to determine soil erosion and the spatial distribution of sediment exports. The InVEST SDR method was used to calculate sediment exports and soil erosion. The results showed that the total sediment export of the Central Citarum watershed was 4.61 x million tons/year or an average of 20.31 tons/ha/year. Significant distributions occur in several sub-watersheds, including Cilawang, Cihalaya, Cipada, Citarum 58, and Cimurah, each contributing 36.56%, 14.83%, 13.70%, 4.73%, and 4.53 %. Meanwhile, total soil erosion is 23.16 million tons/year or an average of 102 tons/ha/year, with the most extensive distribution in the Cilawang sub-watershed, 35.12%. High sediment discharge occurs in areas with steep slopes, high rainfall, and dry land agriculture. Furthermore, efforts to reduce sediment exports to the Cirata and Jatiluhur reservoirs should focus on these five sub-watersheds.

Published: December 2022

The shift in women’s roles from domestic to public is a phenomenon in the development of the social, economic, and political reality of women. Women’s awareness of non-domestic roles is increasing but their involvement does not mean they are more empowered or that more attention is given to women’s rights. This research describes the shift in women’s roles and their contribution to meeting household needs, and how the empowerment of women is implemented. The research method is descriptive qualitative and the data analysis uses an interactive analysis. The research results show that there is a division of work in daily life, in which men work to fulfil their social needs while women have to bear the burden of their economic needs. This work division is seen in farm management, where men’s work is dominated by crops with a high economic value or livestock farming, while women’s work focuses on crops with a low economic values and small livestock. Empowerment of women is carried out in three ways: capacity building, cultural change, and structural adjustment, based on the social, political, and psychological strengths of women tea pickers.

Climate change and extreme weather have negative impacts on human life. Efforts are needed to prevent environmental damage. In the Indonesian economy, there is a Green Growth Program, which is a program to realize economic growth that can reduce poverty and ensure social inclusion, environmental sustainability, and resource efficiency. One of the programs is green budgeting which consists of actions and fiscal policy to prevent environmental problems. This study focuses on the relationship between green budgeting and financial and development policies, it aims to see how the proportion of the budget is set on finance and development. This study uses a quantitative approach by employing descriptive analysis. Green budgeting has been implemented in Indonesia, but it is facing various problems. At the local level, the government does not understand green budgeting. There is also a lack of data for formulating the next green budgeting policy. Lack of government commitment causes the budget for environmental management not as a priority. This causes the limited local government budget (APBD) allocated. Limited budget constraints have to be overcome by finding other sources, for example, prepare of sustainable programs or environmental approach.

Respondents were taken randomly and the number of respondents was determined using the Slovin formula with a margin of error of 10%, obtaining 212 respondents. The analytical method used was descriptive analysis and rank spearman. The results showed that the motivation of buffalo farmers with the medium to the high category, the perception of farmers was in the high category, and the commitment of buffalo farmers was in the medium to high category. The correlation between the motivation and perception with the commitment of farmers to raising buffalo was in a strong category (0.590 and 0.531).

The mutated plants from Indigofera zolligeriana were screened using 14 SSR primers, to know the polymorphic DNA profiles of mutated plants. For screening these primers we used 12 DNA genomes of mutated I. zolligeriana plants. DNA genomes from 12 mutated plants were isolated. Amplification of 12 DNA genomes using multiplex PCR method followed by optimization of the method to obtain the best band profiles. Screening with the 14 SSR primers showed that not of the 14 primers used could amplify DNA genomes of mutated I. zollingeriana. Five primers showed polymorphic bands at 59°C and 13 primers at 48°C. After all treatments, 12 primers are suitable for use in further DNA profiling of other mutated I. zolligeriana plants.

Published: December 2022

Urea has been utilized as a non-protein nitrogen supplement for ruminants due to its affordable price, abundantly available, easy to use, and positively affect microbial protein synthesis in the rumen. However, urea have a weakness since it is rapidly converted into ammonia in the rumen and may lead to nitrogen loss and even ammonia toxicity. Development of a slow release urea (SRU) is therefore important in order to overcome such potential negative impacts. This experiment was conducted to evaluate the effects of SRU, made by complexing the urea with tannin from chestnut, on in vitro rumen fermentation parameters. The treatments were the addition of different forms and levels of urea into a basal diet, i.e., 1% conventional urea (T0), 1% SRU (T1), 2% SRU (T2), and 3% SRU (T3). Data were analyzed by using analysis of variance and continued with a post-hoc test namely the Tukey’s test. Results revealed that the SRU treatments (T1-T3) reduced (P<0.05) ruminal ammonia concentration at various time point intervals than that of the conventional urea (T0). However, the SRU did not alter microbial protein synthesis and nutrient digestibility. In conclusion, SRU made from tannin is an effective supplement for enhancing nitrogen utilization in the rumen.
CD27 on human memory B cells–more than just a surface marker
Authors: Grimsholm Ola
Published: December 2022

Immunological memory protects the human body from re-infection with an earlier recognized pathogen. This memory comprises the durable serum antibody titres provided by long-lived plasma cells and the memory T and B cells with help from other cells. Memory B cells are the main precursor cells for new plasma cells during a secondary infection. Their formation starts very early in life, and they continue to form and undergo refinements throughout our lifetime. While the heterogeneity of the human memory B-cell pool is still poorly understood, specific cellular surface markers define most of the cell subpopulations. CD27 is one of the most commonly used markers to define human memory B cells. In addition, there are molecular markers, such as somatic mutations in the immunoglobulin heavy and light chains and isotype switching to, for example, IgG. Although not every memory B cell undergoes somatic hypermutation or isotype switching, most of them express these molecular traits in adulthood. In this review, I will focus on the most recent knowledge regarding CD27+ human memory B cells in health and disease, and describe how Ig sequencing can be used as a tool to decipher the evolutionary pathways of these cells.

Published: December 2022

Aims

Psychoeducational interventions focusing on self-management of heart failure (HF) patients may improve patient health knowledge and reduce hospitalizations, but data regarding the effects on caregiver outcomes are inconclusive.

Methods and results

We conducted a single-centre, randomized controlled study to evaluate the effect of a nurse-led educational intervention in dyads of recently hospitalized HF patients and their caregivers on caregiver burden, feelings of guilt and health-related quality of life (HR-QoL). Dyads were randomized to usual care plus intervention group 1 (IG-1) or 2 (IG-2) or usual care only (control group, CG). Educational sessions in IG-1 and IG-2 were initiated before hospital discharge and continued with combination of home visits and telephone sessions in IG-1, or telephone sessions only in IG-2, delivered on regular intervals for 6 months. Caregiver burden was assessed by Heart Failure Caregiver Questionnaire (HF-CQ v5.0), guilt by Caregiver Guilt Questionnaire (CGQ), and QOL by EuroQol EQ-5D. Fifty-seven patient/caregiver dyads were included: 12 in IG-1, 18 in IG-2, and 27 in CG, of whom 11, 16, and 20, respectively, completed the study. All domains of HF-CQ and CGQ improved in IG-1 and IG-2 at 6 months, whereas deteriorated in CG (all P < 0.01). EQ-5D improved in IG-1 and IG-2 only in visual analogue scale part (P = 0.002), but not in the descriptive part.

Conclusion

A nurse-led, 6-month educational intervention on recently hospitalized HF patients/caregiver dyads, delivered through either combined home visits and telephone sessions or telephone sessions only, reduced caregiver burden and feelings of guilt, with lesser effect on HR-QoL.

Published: December 2022

Aims

This retrospective study sought to compare complication rates and efficacy of power-controlled very high-power short-duration (vHPSD) and conventional catheter ablation in a large cohort of patients with atrial fibrillation (AF).

Methods and results

We analyzed 1115 consecutive patients with AF (38.7% paroxysmal, 61.3% persistent) who received first-time catheter ablation at our centre from 2015 to 2021. Circumferential pulmonary vein isolation ± additional substrate ablation using an irrigated-tip catheter was performed with vHPSD (70 W/5–7 s or 60 W/7–10 s) in 574 patients and with conventional power (30–35 W/15–30 s) in 541 patients. Baseline characteristics were well-balanced between groups (mean age 65.1 ± 11.2 years, 63.4% male). The 30-day incidence of cardiac tamponade [2/574 (0.35%) vs. 1/541 (0.18%), P = 0.598], pericardial effusion ≥ 10 mm [2/574 (0.35%) vs. 1/541 (0.18%), P = 0.598] and transient ischaemic attack [1/574 (0.17%) vs. 2/541 (0.37%), P = 0.529] was not significantly different between vHPSD and conventional ablation. No stroke, atrio-esophageal fistula, cardiac arrest or death occurred. Procedure (122.2 ± 46.8 min vs. 155.0 ± 50.5 min, P < 0.001), radiofrequency (22.4 ± 19.3 min vs. 52.9 ± 22.0 min, P < 0.001), and fluoroscopy (8.1 ± 7.2 vs. 9.2 ± 7.4, P = 0.016) duration were significantly shorter in the vHPSD group. At 12 months follow-up, freedom of any atrial arrhythmia was 44.1% vs. 34.2% (P = 0.010) in persistent AF and 78.1% vs. 70.2% in paroxysmal AF (P = 0.068).

Conclusion

vHPSD ablation is as safe as conventional ablation and is associated with an improved long-term efficacy in persistent AF.

Aims

Thyroid dysfunction is considered the most frequent complication to amiodarone treatment, but data on its occurrence outside clinical trials are sparse. The present study aimed to examine the incidence of thyroid dysfunction following initiation of amiodarone treatment in a nationwide cohort of patients with and without heart failure (HF).

Methods and results

In Danish registries, we identified all patients with first-time amiodarone treatment during the period 2000–18, without prior thyroid disease or medication. The primary outcome was a composite of thyroid diagnoses and initiation of thyroid drugs. Outcomes were assessed at 1-year follow-up, and for patients free of events in the first year, in a landmark analysis for the subsequent 5 years. We included 43 724 patients with first-time amiodarone treatment, of whom 16 939 (38%) had HF. At 1-year follow-up, the cumulative incidence and adjusted hazard ratio (HR) of the primary outcome were 5.3% and 1.37 (95% confidence interval 1.25–1.50) in patients with a history of HF and 4.2% in those without HF (reference). In the 1-year landmark analysis, the subsequent 5-year cumulative incidences and adjusted HRs of the primary outcome were 5.3% (reference) in patients with 1-year accumulated dose <27.38 g [corresponding to average daily dose (ADD <75 mg)], 14.0% and HR 2.74 (2.46–3.05) for 27.38–45.63 g (ADD 75–125 mg), 20.0% and HR 4.16 (3.77–4.59) for 45.64–63.88 g (ADD 126–175 mg), and 24.5% and HR 5.30 (4.82–5.90) for >63.88 g (ADD >175 mg).

Conclusion

Among patients who initiated amiodarone treatment, around 5% had thyroid dysfunction at 1-year follow-up, with a slightly higher incidence in those with HF. A dose–response relationship was observed between the 1-year accumulated amiodarone dose and the subsequent 5-year cumulative incidence of thyroid dysfunction.

Published: December 2022

Aims

Atrial fibrillation (AF) is the most common cardiac arrhythmia. Pathogenic variants in genes encoding ion channels are associated with familial AF. The point mutation M1875T in the SCN5A gene, which encodes the α-subunit of the cardiac sodium channel Nav1.5, has been associated with increased atrial excitability and familial AF in patients.

Methods and results

We designed a new murine model carrying the Scn5a-M1875T mutation enabling us to study the effects of the Nav1.5 mutation in detail in vivo and in vitro using patch clamp and microelectrode recording of atrial cardiomyocytes, optical mapping, electrocardiogram, echocardiography, gravimetry, histology, and biochemistry. Atrial cardiomyocytes from newly generated adult Scn5a-M1875T+/− mice showed a selective increase in the early (peak) cardiac sodium current, larger action potential amplitude, and a faster peak upstroke velocity. Conduction slowing caused by the sodium channel blocker flecainide was less pronounced in Scn5a-M1875T+/− compared to wildtype atria. Overt hypertrophy or heart failure in Scn5a-M1875T+/− mice could be excluded.

Conclusion

The Scn5a-M1875T point mutation causes gain-of-function of the cardiac sodium channel. Our results suggest increased atrial peak sodium current as a potential trigger for increased atrial excitability.
