Ramalina sp. (Ramalinaceae) is a type of lichen known to contain many active secondary metabolite compounds that have the potential to be used as medicine or medicinal raw materials. One of the biological activities possessed by Ramalina sp. lichen is its anticancer activity. This research aims to isolate and identify active secondary metabolite compounds from the methanol extract of the Ramalina sp. lichen and to find out the cytotoxic activity of the isolated compound against MCF7 breast cancer cells. Compound 1 (usnic acid) was successfully isolated from fraction A. The isolation and purification process was carried out starting with a maceration process using acetone solvent, followed by silica gel column chromatography using a gradient solvent system consisting of n-hexane, n-hexane: EtOAc, EtOAc, EtOAc: MeOH, and MeOH with 5% increment of polarity to obtain 17 fractions (F-1 to F-17). From the 17 fractions obtained, fraction 3 (F-3) and fraction 4 (F-4) (eluted with n-hexane: EtOAc 30%), which had the same TLC profile, were combined and named as fraction A. Compound 1 (50 mg) is a yellow needle crystal that was formed in a bottle of fraction A, which was obtained after the process of combining fractions F-3 and F-4 and solvent evaporation process. The crystals were then separated and purified with CHCl3 and MeOH. Compound 1 was then characterized based on spectroscopic data. Various spectroscopic analysis data, including FTIR, 1D- and 2D-NMR, and LC-ESI-MS, show that Compound 1 is a dibenzofuran derivative compound with 18 carbons (3 from carbonyl groups (C=O) and 3 from methyl groups) and 2 hydroxyls (-OH). Cytotoxicity assay showed that at a low concentration of 18.75 ug/mL, Com-pound 1 caused a 67.06% decrease in MCF7 viability.

Mycobacterium leprae is an acid-fast bacterium that causes leprosy diseases, which remains a problem worldwide. Even though leprosy prevalence in the world has decreased significantly, many endemic pocket areas continue reporting new cases and harbor M. leprae in the environment, including water and soil. The presence of obligate intracellular bacteria-M. leprae in the environment raises a question on how it survives. Free-living amoeba has been proposed as its reservoir host in the environment. The study was conducted to give evidence that M. leprae can survive inside free-living amoeba isolated from water sources of leprosy endemic areas. M. leprae from leprosy patients was cultured together with Acanthamoeba sp. isolated from the water source of the leprosy endemic area. Viability and duplication of M. leprae inside amoeba then observed at days 14 and 28 using reverse transcriptase PCR and qPCR. The results showed that M. leprae survived inside the amoeba until day 28, but no bacterial replication was observed. The study reveals in vitro evidence of viable M. leprae inside free-living amoeba of leprosy endemic area environment

Dysbiosis, marked by a decline in Firmicutes (such as Clostridium spp.) and a rise in Proteobacteria (such as Escherichia coli), is recognized as a pathway linked to the progression of non-alcoholic fatty liver disease (NAFLD). High-fat food may influence the development of NAFLD. This study investigates the effect of different high-fat diets on gut microbiota composition and butyrate levels in a rat model. Four groups of Rattus norvegicus strain Wistar (n=27) were fed specific diets for 12 weeks: normal diet (ND, n=7), high-fat diet (HFD, n=6), western diet (WD, n=7), and high-fat-high-fructose diet (HFHFD, n=7). Stools were cultured on Eosin Methylene Blue (EMB) for Escherichia coli and Forget Fredette Agar (FFA) for Clostridium spp. Colonies were counted using Total Plate Count (TPC), and butyrate levels were measured with gas chromatography. Liver histology was assessed with the NAFLD activity score (NAS). Gut microbiota were analyzed using Crosstab and Chi-Square tests, and butyrate levels with the Kruskal-Wallis test. Butyrate levels decreased in NAFLD-inducing diet groups (HFD, WD, HFHFD) compared to ND (p=0.021). Escherichia coli colony counts were significantly higher in NAFLD-inducing diet groups (p=0.048), while Clostridium spp. counts were higher in ND (p=0.001). Liver histological changes, particularly in the WD group, resembled NAFLD. These findings imply that different high-fat diets can alter the gut microbiome, potentially influencing NAFLD development.

The success of embryo transfer in cattle may depend on several factors. The blood progesterone level of the embryo recipient would be one of the main factors secondary to the size and quality of the corpus luteum. Per-rectal palpation and by-hand grading of corpora lutea have been practiced routinely, even under commercial embryo transfer programs in cattle. This experiment aimed to evaluate the accuracy of the per-rectal hand grading technique of mid-phase corpora lutea in embryo recipient cows. A group of healthy cows (Friesian× Jersey, n=25), which had been selected as recipient animals with the special consideration of reproductive history in an embryo transfer program, was used in this study. Estrous of those animals were synchronized using a standard progesterone intravaginal devise-PGF2α protocol. Conven-tional evaluation and grading of corpora lutea were conducted at the per-rectal hand grading as 'A', 'B', 'C' and 'Cystic' (If diameters; < 1cm=C, 1-1.9cm=B, 2-2.5cm= A, >2.5cm= Cystic). In this study, the accuracy of those hand-grading techniques was evaluated using ultra-sound scanning technology on the same day. Identification accuracy of grades C, B, A, and Cysts in hand grading technique was 45%, 56%, 67%, and 50%, respectively. The average accuracy in the hand grading technique was 52%, and identification accuracy as suitable (A or B) corpora lutea for embryo transfer was 76%. Results raised the 24% probable loss of embryo transferrable recipients due to the hand-grading technique. Further, 8% of unsuitable cows can be selected as embryo recipients due to the practice of hand-grading techniques at embryo transfer programs. Although higher accuracy is a characteristic of the hand grading technique, the technology causes considerable loss due to inaccurate selection probability of recipients at embryo transfer programs.

The effect of inoculation of a combination of the arbuscular mycorrhizal fungus of Glomus and Acaulospora on micropropagated banana plantlets cultivar Raja from Bali during the acclimatization phase was investigated. The experiment was conducted at the Experimental Station of the Faculty of Agriculture, Udayana University, Denpasar, Bali, Indonesia, over the period of March to June 2022. The objective of this research was to evaluate the impact of various doses of mycorrhizae on the growth of tissue culture banana plantlets that had undergone acclimatization for a period of six weeks. A total of five different doses of mycorrhiza were applied to the acclimatized plantlets, namely M0=without mycorrhiza and M5=5g mycorrhizal. kg1, M10=10 g mycorrhiza.kg-1, M15=15 g mycorrhiza.kg-1, M20=20 g mycorrhizal. kg 1. A significant effect was discovered at M15; however, compared to M20, M20 gave better results for root length and fresh weight of the above-ground part, indicating the best dose was 20 g mycorrhiza kg-1. This study concluded that mycorrhiza has a very significant role in supporting the growth of micro-propagated banana plantlets at post-acclimatization. Variables observed, such as the average number of leaves, stem diameter, above-ground plant fresh and dry weight, and root fresh and dry weight, increased with the application of AMF (Glomus and Acaulospora).

Acute lung injury tends to be induced by infection or sepsis that disrupts alveolar and vascular permeability, neutrophil influx, and edema. Those impairments are worsened by the increase of oxidative stress along with hyperinflammation response. Oxidative stress in lung tissue could be indicated by malondialdehyde (MDA) and nuclear fac-tor erythroid 2-related factor 2 (Nrf2) expression. This research aimed to evaluate the efficacy of Baby Java citrus peel extract (BJE) in suppressing oxidative stress and preventing lung injury in lipopolysaccharides (LPS)-induced mice. Twenty-five male BALB/c mice were divided into five groups consisting of untreated (N), LPS (A), and LPS-induced followed by treatment using BJE at various doses: 75 mg/kg BW (BJE-1), 105 mg/kg BW (BJE-2), and 150 mg/kg BW (BJE-3). Lungs were isolated for histopathological analysis also detection of MDA and Nrf2 using flow cytometry. BJE at the dose of 105 mg/kg BW could inhibit the alteration of lung histology following LPS challenge including alveolar and interstitial neutrophil infiltration, proteinaceous debris, and septal thickening. The same dose also showed good potency in suppressing MDA and Nrf2 levels as oxidative stress indicators. Our findings demonstrated the protective effects of Baby Java citrus peel in acute lung injury and oxidative stress prevention after LPS exposure

Cancer is an incurable fatal disease wreaking havoc on the population of countries either developed or developing. Hepatocellular carcinoma (HCC) is the fifth most frequent type of cancer having a poor prognosis. Globally, HCC management and treatment intervention using medicinal plants from generation to generation is rapidly increasing and remains an area of promising research. This review provided insight into medicinal plants' ethnomedicinal use, photochemistry and mechanisms of action on HCC exhibiting anti-cancer potentials subjected to scientific investigations. Furthermore, clinical, toxicity studies and detailed mechanisms of action would provide an understanding of the development of lead compounds in drug discovery and development for HCC.

The study proposed identifying the changes in bacterial community and diversity and exploring the potential correlations among sediment parameters and benthic bacterial communities under different mangrove ecosystem rehabilitation statuses. Three sites were investigated, 1. Kampung Blekok (KB) as the long rehabilitation period site; 2. Banyuurip Mangrove Center (BMC) as the short rehabilitation period site; 3. Pulau Lusi (PL) as the reclamation site. The physicochemical parameters and benthic bacteria from the mangrove sediment of the three locations were observed. The data were analyzed statistically to determine the sites' variation and the correlation between parameters. The results found that the physicochemical parameters among restoration sites varied. Soil organic matter (SOM) in long and short-rehabilitation period sites was more than 1.5-fold higher than those in the reclamation site. Cation exchange capacity (CEC), calcium and potassium ions, and soil conductivity of the restoration site have higher values and can reach more than 1.3 fold compared to the other sites. According to diversity indices and taxa richness, benthic bacteria in the restoration were the most diverse. Proteobacteria dominated in natural and restoration sites; meanwhile, Firmicutes dominated in the reclamation site. Sulfurovum aggregans were found abundant in the long and short rehabilitation sites; meanwhile, Mesobacillus subterraneus was the dominant species in the reclamation site. Furthermore, the bacterial taxa richness was positively correlated with SOM and the bacterial diversity was correlated with CEC and conductivity.

The Human Epididymis Protein 4 (HE4) biomarker has been extensively investigated for its potential in diagnosing ovarian cancer (OC). For the application of diagnostic techniques and drug delivery, it is crucial to understand the protein tertiary structure. However, the Protein Data Bank (PDB) does not currently contain the three-dimensional (3D) structure of HE4. Therefore, an in silico analysis was conducted to model the HE4 protein using AlphaFold, I-TASSER, and Robetta servers, with the sequence retrieved from UniProt (ID: Q14508). These three servers employed deep learning algorithms, threading templates, and de novo methods, respectively. Subsequently, Molecular Dynamics (MD) simulation using the GROMACS software package improved each 3D structure model, resulting in optimized and refined structures: RF1, RF2, and RF3. PROCHECK and ERRAT programs were employed to assess the structure quality. The Ramachandran plots from PROCHECK indicated that 100% of residues were within the allowed regions for all servers except for I-TASSER. For the refined structures, RF1 and RF3, all residues were concentrated within the allowed regions. According to the ERRAT program, the RF1 model exhibited the highest overall quality factor of 97.701, followed by RF3 and AlphaFold models with scores of 94.643 and 93.750, respectively. After these validations, RF1 emerged as the most accurately predicted 3D structure of HE4 and has one tunnel identified by CAVER 3.0 tool that facilitates the transportation of small particles to the active site, supported by FTsite and PrankWeb binding site predictions. This model holds potential for various computational studies, including the development of OC diagnostic kits. It will enhance our comprehension of the interactions between the protein and other biomolecules.

Ferritin is an acute-phase reactant that is elevated in autoimmune disorders, including systemic lupus erythematosus (SLE). However, their correlation with disease activity scores has not been confirmed. Pandemic Covid-19 makes children visitation to hospital to get the treatment of SLE were delayed. This study aimed to evaluate correlation between serum ferritin and disease activity and its role in screening for flare in pediatric SLE (pSLE) patients during pandemic Covid-19. This is a cross-sectional study conducted in Saiful Anwar General Hospital Malang. Sampling was carried out sequentially on pediatric patients who met the criteria for Systemic Lupus International Collaborating Clinics (SLICC) and were recorded between July 2021-May 2022. All patients were interviewed and assessed for disease activity using SLE Disease Activity Index 2000 (SLEDAI-2k). A score <4 was categorized as inactive disease. Biochemical, serological tests including markers of disease activity and ferritin level were measured by standard laboratory procedure. Comparison, correlation and ROC curve analyses were performed with SPSS software. There were 38 females pSLE participated in this study. The mean age of the patients were 12.6 ± 3.02 years. Serum ferritin significantly higher in active disease compared to inactive disease 84.50 ng/mL (68.00-151.75 ng/mL) ng/mL and 815.00 ng/mL (451.25-1570.00 ng/mL), a value of p<0.05 was determined to be statistically significant. A significant correlation was found between serum ferritin with SLEDAI 2K (r = 0.890, p = 0.000). Correlation was also found between serum ferritin and IgM anti-double stranded-DNA (r = 0.325, p = 0.046), but not with other laboratory and serological parameters. In ROC curve analysis, we found that Area Under The Curve (AUC) 0.989, 95%CI 0.964-1.014, p value 0,000, with cut off value 297.50 with sensitivity 85% and specificity 94.4%. Ferritin was increased in active disease as compared to inactive disease and correlated with SLEDAI score and IgM-dsDNA. Thus, ferritin may be potential as an affordable and available marker of disease activity in pSLE during pandemic Covid-19.
