Abstract

The improved growth performance of chicks determines the production efficiency of chicken to local chicken farmers. Little has been done to understand the contribution of management systems and practices to the growth performance of chicks from farmers who are involved in rearing local chickens in Dodoma. We focused on assessing how the growth performance of chicks (length and weight) from local chicken farmers is affected by management systems (Free range and semi-intensive systems), management practices such as water provision, supplement feeding, regular cleaning, flock size, and size of banda (hut) used to raise chickens. Data were collected for 8 rounds within 2 months (once per week) from 5 farmers in three wards: Nkuhungu (n=2), Mbwanga (n=2), and Mtube (n=1). In each round, data were collected from 10 chicks per farmer (n=400 chicks for all 8 rounds and 5 farmers). Kruskal Wallis was used to determine the variation in growth performance while generalized linear model was used to assess the effect of flock size, management system on the growth performance of chicks. Growth performance was significantly increased and affected by age (P<0.05). The management system significantly contributed to the growth performance of the chicks (P<0.001). In addition, the small size of the banda (hut) with large flock size reduced the growth performance of chicks due to increased competition in terms of space, supplements, water supplied, feed provided, and treatment (P<0.05). In raising local chicken, local farmers need to be concerned in applying management practices such as supplement feeding, treatment, flock size and size of huts.

Abstract

The COVID-19 pandemic, which started in the beginning of 2020 was triggered by a new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, severely affected various sectors, especially health. The effect of COVID-19 on patients is exacerbated by bacterial co-infections and secondary bacterial infections. There are few studies on how bacterial co-infections and secondary bacterial infections worsen COVID-19 patients, including in Indonesia. Therefore, it is necessary to update and summarize the understanding of bacterial infections characteristics to help optimize the diagnosis, prevention, and treatment decisions. Antibiotics have been used in COVID-19 patients to treat bacterial infections to date, which could contribute to antimicrobial resistance in the future. The review's objective is to summarize bacterial infections in COVID-19 patients and several possible treatments, including antibiotics, phage therapy, probiotics/prebiotics, and nanomedicine for antimicrobial peptides (AMPs) delivery

Abstract

This study was designed to evaluate the role of sliced and dropping models of neem leaves (Azadirachta indica) and environmental factors on zebrafish wound shrinkage. This study employed two treatment models: neem leaf slices and drops model. The treatment in the neem leaf slice model was the control group (fish was injured without neem leaf slices treatment, and G1-G3 of each fish was injured at 0.3 cm + 0.5, 1, and 2 g. Treatment in the neem leaf drop model was control group (fish was injured without neem leaves drops, and G1-G3 of each fish was injured at 0.3 cm + 1, 2, 4 drops. Findings suggest that there is a significant difference between the control group by treating G1, G2, and G3 on the shrinkage of zebrafish wound area both in the neem leaf slice and drop models, but G1 was not significantly different from G2 and G3, as well as G2 and G3 both in the neem leaf slice and drop model. Neem leaves contain nutrients that play a vital role in the formation of collagen and the formation of new capillaries to help speed up the wound healing process. The healing process involves the dynamic interaction of physiological factors.

Abstract

Vaccines based on epitope are alternative treatments for snakebite aside from anti-venom immunoglobulin, which is specific and not cross-reaction. However, the potential kistomin epitope has not been known. This study identified the region of T cells epitope and evaluated their immunogenicity to induce an immune response by in-silico. Sequences of kistomin were collected from Swiss-Prot with ID P0CB14. The physico-chemical and conserved domain of kistomin were predicted by using ProtParam and the NCBI database. The T cell epitope was predicted by using the Artificial Neural Network (ANN) method on the IEDB website. Epitopes with MHC-IC50 values >250 nM were further analyzed for conservation and immunogenicity on the IEDB website as well. After that, the candidate 9-mer epitope was interacted by simulated docking with four Major Histocompatibility Complex (MHC) molecules (5ENW, 6VB0, 3PGD, 6DIG). The conserved 9-mer epitope candidates with high immunogenicity and having similarities with the 15-mer epitope candidates are 4-VLLVTICLA-12 and 27-NVNDYEVVY-35. The 4-VLLVTICLA-12 candidate epitope interacted at β-sheet structure of four MHC. In contrast, The 27-NVNDYEVVY-35 candidate epitope interacted at α-helix and β-sheet structures of HLA-B*15:02 MHC. This study suggested 27-NVNDYEVVY-35 is potentially used as vaccine from envenomation Calloselasma rhodhostoma. In future studies, other alelles can be used to predict epitope from metalloproteinase domain in kistomin.

Abstract

Nauclea orientalis L. is widely distributed in Indonesia. Secondary metabolites such as flavonoids, polyphenols, and saponins are abundant in the bark of N. orientalis L. These compounds have the potential to act as antioxidants. Endophytic fungi, through genetic transfer and coevolution, can produce the same metabolites as their host plant. As a result, understanding the potential of endophytic fungi from N. orientalis L. to produce antioxidant compounds that can be developed is critical. According to the findings of this study, twelve isolates have the potential to produce secondary metabolites with antioxidant properties. Three isolates had high antioxidant activity: DB2 was identified as Aspergillus minisclerotigenes with an IC50 of 21 g/mL containing tannins, terpenes, and flavonoids, AB3 as Colletotrichum perseae with an IC50 of 31 g/mL containing tannins and terpenoids, and AB1 as Diaporthe tulliensis with an IC50 of 48 g/mL containing tannins. The secondary metabolite group has the potential to be developed into an antioxidant agent

Abstract

In the cytokinesis-block micronucleus (CBMN) assay, micronuclei (MNi), nucleoplasmic bridges (NPBs), and nuclear budding (NBUD) are the most commonly analysed morphological types of nuclear abnormalities. In contrast, tailed and dumbbell-shaped nucleus have historically received little attention in the CBMN assay. Interestingly, the incidence of tailed and dumbbell-shaped nuclei in lymphocytes is closely related with that of dicentric chromosomes or NPBs in the CBMN assay. To provide a better picture of the implications and significance of tailed and dumbbell-shaped nuclei as markers of radiation exposure, a literature review was performed in this study. Twenty articles were found in PubMed, PubMed Central, and manually searched. The articles were screened and those that met the inclusion criteria and did not meet the exclusion criteria were reviewed by all authors. At the end, nine articles were included. In conclusion, the assessment of in vivo tailed nuclei in blood smears and accounting for the occurrence of dumbbell-shaped nuclei in the CBMN assay can increase the sensitivity of the CBMN assay for biodosimetry involving a high dose exposure.

Abstract

The unprecedented growth of human-dominated landscapes has led to population decline and the extinction of many animal species. A major paradigm shift that perceived wildlife as problem animals into threatened species that need protection triggered human-wildlife conflict studies. Although human-wildlife conflict incidences can be found globally, they have unique characteristics in each region of the world. However, little is known about the characteristics of human-wildlife conflicts in Southeast Asia, particularly Indonesia. There is a need for a comprehensive insight into human-wildlife conflict studies in Indonesia to understand past advancements and propose future priorities. This study examined the literature that provides the overall view of the human-wildlife conflict patterns in the country. The results showed that there was a comparatively small number of studies because this field was a relatively new subject in Indonesia. Furthermore, there were big gaps regarding animal species and the geographic distribution of study sites. A total of 35 species belonging to eight taxonomic groups experienced conflicts with humans. However, the studies heavily focused on three groups of animals and certain areas of the country. The predominant conflict sites were secondary forest, agroforestry, and farmlands. The conflicts in these areas unveiled the significance of local beliefs and social norms for formulating mitigation strategies.
