Insulin resistance, which affects insulin-sensitive tissues, including adipose tissues, skeletal muscle, and the liver, is the central pathophysiological mechanism underlying type 2 diabetes progression. Decreased glucose uptake in insulin-sensitive tissues disrupts insulin signaling pathways, particularly the PI3K/Akt pathway. An in vitro model is appropriate for studying the cellular and molecular mechanisms underlying insulin resistance because it is easy to maintain and the results can be easily reproduced. The application of cell-based models for exploring the pathogenesis of diabetes and insulin resistance as well as for developing drugs for these conditions is well known. However, a comprehensive review of in vitro insulin resistance models is lacking. Therefore, this review was conducted to provide a comprehensive overview and summary of the latest in vitro insulin resistance models, particularly 3T3-L1 (preadipocyte), C2C12 (skeletal muscle), and HepG2 (liver) cell lines induced with palmitic acid, high glucose, or chronic exposure to insulin.

Background: Transmission of pathogenic and non-pathogenic microorganisms from animals to humans can affect the composition of gut bacteria (gut microbiome) in humans and can also be a potential source of transmission of zoonotic diseases. Therefore, this study aimed to analyze the gut microbiome interactions between the human and the livestock. Method: This study was a cross-sectional study conducted in Mlati District, Slemanm Yogyakarta. The fecal sample was used to identify parasites by using trichrome staining. Then NGS selected samples were used to analyze the gut microbiome using Illumina high throughput 16S rRNA region V3-V4 sequencing. Result: The analysis showed that Bacteroidetes was prevalent in the HCA group (57%), while Firmicutes (70%) were commonly found in HNC. Regarding the potential parasitic infection, direct microscopic examination and trichrome staining showed that Blastocystis sp and Entamoeba coli cyst was found in several subjects in HCA groups, with prevalence rate at 7.69% and 2.5%. Meanwhile, no parasite was found in HNC feces. Conclusion: There was a significant difference in the gut microbiome and parasitic infections between the HCA and HNC groups, with Blastocystis sp and Entamoeba coli as the most prevalent parasites.

Infections caused by parasites infect millions of people worldwide, especially in developing countries. Most parasites have a life cycle that lives in hosts (animals or humans) and the environment; thus, the One Health approach is an advanced strategy to overcome these challenges. Recently, One Health has become important as it considers several factors of the connection between humans, animals and the environment. This study aims to understand the One Health Approach as a strategy to prevent and control parasitic zoonosis globally and in Indonesia. We used a literature review using PubMed and Google Scholar based on PRISMA guidelines. Our review identified 22 recommendations and applications of the One Health strategy to handle zoonotic parasitic diseases globally and in Indonesia. There are theoretical and practical gaps in the implementation of this strategy. Further studies are needed to implement better One Health of combating parasitic zoonosis globally and in Indonesia.

Background: Coronavirus Disease 2019 (COVID-19) is an easily contagious disease, and not much is known about the characteristics of COVID-19, both in terms of susceptibility, severity, and spreadability of various SARS-CoV-2 strains. Patient genomic factors, especially related to genomic polymorphisms that affect the body's immune system, can influence the course of infectious diseases. The aim of this study is to get an adequate picture regarding gene polymorphisms, both susceptibility and related to the clinical degree in COVID-19 patients. Methods: The PCR preparations were carried out in the Biomedical laboratory of the Faculty of Medicine, Universitas Sebelas Maret. The qualitative PCR (qPCR) examination was sent to the Genetica Science laboratory, Tangerang, West Java. The research subjects were divided into 3 groups, namely COVID-19 patients with no symptoms, COVID-19 patients with mild-moderate symptoms, COVID-19 patients with severe-critical symptoms. The research subjects were taken 6 cc of venous blood (3 cc for examination of serum IL-6 and TNFα levels and 3 cc for DNA examination). Results: Serum levels of IL-6 and TNF-α in the clinical grade group were almost all above normal values. The frequency of TNF- α polymorphisms (-376G/A) all showed homozygote GG. TNF-α (-308G/A) also showed homozygote GG was dominant for SARS CoV2. IL-6 (-572G/C) polymorphism for cases requiring medium and severe clinical degree hospitalization was found to have more C allele than G allele. IL-6 polymorphism (intron A/G) the G allele is less common in cases requiring hospitalization. Conclusion: TNF-α(−308A) allele has an influence on the development of clinical symptoms of SARS CoV2 infection. The rs1800796GG genotype in the IL-6 promoter contributes to milder symptoms in SARS CoV2 infection. Allelic variants of the gene under study may show different effects in other races depending on their interactions with other risk factors.

Introduction: To date, no specific therapeutic drug has been approved to target SARS-CoV-2. Hence, it remains a major challenge to decide what potential therapeutic regimens to treat COVID-19 patients. This study aims to investigate curcumin and virgin coconut oil (VCO) effects on cytokine levels (IL-1β, IL-2, IL-6, IL-18, TNF-α, and IFN-β) in COVID-19 patients. Methods: This study was a single-center, controlled trial with a parallel Arm or a Randomized Clinical trial design. A total of sixty COVID-19 patients admitted to the Universitas Sebelas Maret Hospital, Surakarta, Indonesia, were divided into two groups. The first group, consisting of 30 patients, was treated with Azithromycin 500 mg + Oseltamivir 2×75 mg + Hydroxychloroquine 400 mg/day for 5 days. The second group, comprising 30 patients, was treated with Azithromycin 500 mg + Oseltamivir 2×75 mg + Hydroxychloroquine 400 mg/day for 5 days, added with VCO 30 mL and curcumin 3×1 g/day for 21 days. The cytokine profiles of the serum samples were analyzed by the enzyme-linked immunosorbent assay (ELISA) on days 1, 14, and 21. Results: Our study showed that the second group had a significant reduction in IL-1β, IL-2, IL-6, TNF-α, and IFN-β levels after being treated with standard therapy added with curcumin and VCO on day 21 (p<0.05). Conclusion: These results su ested that curcumin and VCO mi ht benefit the treatment of COVID-19 atients

Abstract: Giardiasis is a gastrointestinal disease caused by the protozoan Giardia sp. Recent data showed that constant contact with livestock could pose greater risk of contracting this disease, especially without any protective gears. Unfortunately, this condition is still prevalent in several areas in Indonesia. Therefore, this study was aimed to evaluate the prevalence of giardiasis and its risk factors in the community around livestock areas and rivers in Mlati, Sleman, DIY, Indonesia. Methods: A cross-sectional study was conducted from JanuaryAugust 2019 around the livestock area and rivers in Mlati, Sleman, DIY. Stool samples were obtained from subjects who have livestock and live along the rivers or its tributaries. The status of Giardiasis were determined from microscopic examination and PCR using beta-giardin as the reference conducted in Parasitology and Biomedical Laboratory, Faculty of Medicine, UNS. Results: A total of 179 subjects were were enrolled in this study. The prevalence of giardiasis among study population was found to be at 5.02% (n=9), 19 (10.6%) of them were cattleman, and 122 (68.1%) had a history of contact with cattle. Subjects who did not own any cattle seemed to have a significantly lower risk of contracting giardiasis (AOR: 0.041, 95%CI: 0.009-0.185; p=0.000) since contact with cattle also proved to be the risk factor of giardiasis (AOR: 1.080, 95%CI: 1.027-1.135; p<0.002). Conclusion: This study revealed that constant contact with cattle lead to significantly higher risk of giardiasis for those who live among livestock and along the rivers in Mlati, Sleman DIY.

Toxoplasma gondii Surface Antigen 1 (SAG1) is often used as a diagnostic tool due to its immunodominant-specific as antigen. However, data of the Toxoplasma gondii SAG1 protein from Indonesian isolate is limited. To study the protein, genomic DNA was isolated from a Javanese acute toxoplasmosis blood samples patient. A complete coding sequence of Toxoplasma gondii SAG1 was cloned and inserted into an Escherichia coli expression plasmid and sequenced. The sequencing results were subjected to bioinformatics analysis. The Toxoplasma gondii SAG1 complete coding sequences were successfully cloned. Physicochemical analysis revealed the 336 aa of SAG1 had 34.7 kDa of weight. The isoelectric point and aliphatic index were 8.4 and 78.4, respectively. The N-terminal methionine half-life in Escherichia coli was more than 10 hours. The antigenicity, secondary structure, and identification of the HLA binding motifs also had been discussed. The results of this study would contribute information about Toxoplasma gondii SAG1 and benefits for further works willing to develop diagnostic and therapeutic strategies against the parasite.

Diagnosis and identification of the genetic group of T. gondii (Toxoplasma gondii) are important to control better the T. gondii infection, particularly in immunocompromised people as HIV patients. This study aimed to identify strain-specific variations in T. gondii GRA1, GRA5, GRA6, GRA8, and GRA14 in order to help design such diagnostic tool to detect and characterize the parasite. Forty-three T. gondii GRA1, GRA5, GRA6, GRA8, and GRA14 sequences deposited in GenBank were aligned. A number of positions in the gene sequences were highly conserved. All GRA sequences had strain-specific positions, however, only GRA1, GRA5, and GRA6, which contained specific variations for each T. gondii lineage. In conclusion, T. gondii GRA1, GRA5, GRA6, GRA8, and GRA14 are predicted to contain highly conserved regions and positions with strain-specific variation, which might be useful for the design of diagnostic tools detecting and distinguishing T. gondiistrains.

The dense granular (GRA) proteins of Toxoplasma gondii(T. gondii) have been demonstrated as potential sources of T. gondii vaccine antigens. However, data of the GRA5 protein are limited. This study analyzed twenty-one complete GRA5 sequences of T. gondii GT1, RH, ME49, VEG, MAS, RUB, FOU, p89, VAND, and GAB2-2007-GAL-DOM2 strains to identify potential epitopes restricted by Major Histocompatibility Complex class II (MHC- II) molecules (human leukocyte antigen (HLA)-DP, HLA-DQ, and HLA-DR) in the protein. In all T. gondii strains, peptides positioned at amino acid (aa) 15-29, 16-30, 17-31, 18-32, 19-33, 83-97, 84-98, 86-100, 87-101, 89-103, and 90-104 were predicted to pose high affinity and binding with HLA-DRB1*0101, HLA-DRB1*0301 (DR17), HLA-DRB1*0401 (DR4Dw4), HLA-DRB1*0701, HLA-DRB1*1101, HLA-DRB1*1501 (DR2b), and/or HLA-DRB5*0101. Considering the epitope's affinity, ligation strength, and hydrophilicity, LRLLRRRRRRAIQEE sequence (aa 90-104) restricted by HLA-DRB1*0101, HlA- DRB1*0301 (DR17), and HLA-DRB1*0401 (DR4Dw4) was considered as the most potential MHC-II epitope in GRA5 of T. gondii. These results would be useful for studies concerning in developing T. gondii vaccine and diagnostic method.

Abstract Objective To investigate the association of polymorphisms in genes that code for interferon-γ (IFN-γ) and interleukin-10 (IL-10), which play important roles in Toxoplasma gondii ( T. gondii ) infection, with the occurrence of T. gondii co-infection in HIV patients. Methods The IFN-γ +874A/T and IL-10 −1082A/G polymorphism statuses of 306 HIV seropositive samples were characterized using PCR. The polymorphism statuses were analyzed together with the clinical data for each patient. Results Immunoglobulin M anti- T. gondii seropositivity was associated with high IL-10 levels [adjusted odds ratio (OR): 0.4, 95% confidence intervals ( CI ): 0.181–0.825; P = 0.014], but not with either the IL-10 −1082A/G or IFN-γ +874A/T polymorphism. In addition, the IFN-γ +874A allele was associated with immunoglobulin G (IgG) anti- T. gondii seropositivity (OR: 1.5, 95% CI : 1.043–2.193; P = 0.029). In patients with CD4 + T cell levels ≥ 200 cells/µL, the IFN-γ +874 AA genotype was associated with IgG anti- T. gondii seropositivity (adjusted OR: 2.5, 95% CI : 1.278–4.950; P = 0.008). Conclusions The IFN-γ +874A/T polymorphism is associated with IgG anti- T. gondii seropositivity. This polymorphism might be useful to predict the susceptibility of HIV patients to toxoplasmosis.

BACKGROUND
Data regarding the influence of the APOBEC3B deletion on infectious diseases remain limited and shown discrepancies.
OBJECTIVES
To characterize the APOBEC3B deletion polymorphism status and its association with prevalence of co-infection with blood-borne pathogens in Indonesian HIV-infected individuals.
MATERIALS AND METHODS
A total of 597 HIV-positive blood samples were tested for the hepatitis B virus (HBV), hepatitis C virus (HCV), Torque Teno virus (TTV), GB virus-C (GBV-C), and Toxoplasma gondii. Nucleic acid was extracted from plasma samples and used for the molecular detection of HIV RNA, HBV DNA, HCV RNA, TTV DNA, and GBV-C RNA, whereas HBsAg, anti-HCV, IgM and IgG anti-T. gondii were detected through serological testing. The APOBEC3B deletion polymorphism was genotyped by polymerase chain reaction (PCR).
RESULTS
The deletion genotype was associated with HCV viremia (p<0.001) as well as elevated IgG anti-T. gondii (adjusted OR [aOR]=3.4). The deletion genotype was also associated with decreased levels of HBsAg (aOR=0.03), and anti-HCV (aOR=0.1). D/D was frequently found in HIV-infected individuals with CD4+T cells<14% (aOR=5.8). The intact genotype was associated with a reduced likelihood of a CD4+T cell count<200 cells/μL (aOR=0.2) but a higher prevalence of TTV co-infection (aOR=8.6).
CONCLUSIONS
The APOBEC3B deletion polymorphism was found to be associated with HBV, HCV, TTV, and T. gondii co-infection in Indonesian HIV-infected individuals.

Objective: This study was conducted to determine the distribution of the single nucleotide polymorphism (SNP) at position -1082 of the proximal promoter region of the interleukin (IL)-10 gene and its association with hepatitis virus co-infection in Indonesian Javanese human immunodeficiency virus (HIV)-infected patients. Methods: Blood samples were collected from 156 Indonesian Javanese HIV-infected patients; tested with serological and molecular assays for hepatitis B virus (HBV), hepatitis C virus (HCV), and hepatitis D virus (HDV); and subjected to SNP -1082 G/A polymorphism analysis. Results: Hepatitis B surface antigen (HBsAg) (+)/HBV DNA (+), HBsAg (-)/HBV DNA (+), anti-HCV antibodies (+)/HCV RNA (+), and anti-HCV antibodies (-)/HCV RNA (+) were detected from all of HIV-infected individuals at rates of 3.8% (6/156), 0.6% (1/156), 16.0% (25/156), and 11.5% (18/156), respectively. The frequencies of -1082 GG, -1082 GA, and -1082 AA were 14.7% (23/156), 60.3% (94/156), and 25% (39/156), respectively. HBV co-infection was found only in -1082 A allele carriers, and these patients also showed higher rates of HCV co-infection (odds ratio: 2.24, 95% confidence interval: 1.22–4.10, P=0.009).
