Background: Despite the decreasing cases, SARS-CoV-2, with its endemic status, still threatens public health, and developing a variant-proof vaccine could be a promising strategy to prevent future infection. In this study, utilizing immunoinformatics and reverse vaccinology, we aimed to develop a multi-epitope mRNA vaccine with high population coverage, targeting multiple variants of SARS-CoV-2.

Methods: To design a multivariant vaccine, 20,567 sequences consisting of all SARS-CoV-2's variants of concern whole genome were retrieved.

As an important crop, bananas still encounter fruit quality and shelf-life problems that are affected by the ripening process. Improving postharvest technologies may effectively address these challenges, such as by studying the ripening mechanism of banana cultivars with a slow ripening process. A banana cultivar that exhibits this characteristic is Musa balbisiana cv.

Agarwood is a highly prized resinous wood produced by select members of the Thymelaeaceae plant family. Its formation in Aquilaria species has been expedited using various induction techniques, revealing insights into factors affecting the chemical constituents of artificially induced agarwood. Building on this, our research delved into the potential of another Thymelaeaceae member, Gyrinops versteegii, as an alternate agarwood source.

Background: The marine environment boasts distinctive physical, chemical, and biological characteristics. While numerous studies have delved into the microbial ecology and biological potential of the marine environment, exploration of genetically encoded, deep-sea sourced secondary metabolites remains scarce. This study endeavors to investigate marine bioproducts derived from deep-sea water samples at a depth of 1,000 m in the Java Trench, Indonesia, utilizing both culture-dependent and whole-genome sequencing methods.

Background And Purpose: Massive vaccine distribution is a crucial step to prevent the spread of SARS-CoV2 as the causative agent of COVID-19. This research aimed to design the multi-epitope self-amplifying mRNA (saRNA) vaccine from the spike and nucleocapsid proteins of SARS-CoV2.

Experimental Approach: Commonly distributed constructions class I and II alleles of the Indonesian population were used to determine peptide sequences that trigger this population's high specificity T-cell response.

Article Synopsis
  • Deep-sea bacteria thrive in extreme conditions like low light, high pressure, and nutrient scarcity, developing unique survival strategies in their habitat.
  • This study investigated the biodiversity of these bacteria in Indonesian waters, specifically in the Makassar and Lombok Strait, using advanced DNA sequencing techniques to create a genomic database.
  • Findings showed that bacteriological communities at station 48 and 50 were more similar than those at station 33, with the most common bacterial phyla being Proteobacteria and Firmicutes, alongside key genera that adapt to deep-sea environments.

The heterogeneity of the lung microbiome and its alteration are prevalently seen among chronic lung diseases patients. However, studies to date have primarily focused on the bacterial microbiome in the lung rather than fungal composition, which might play an essential role in the mechanisms of several chronic lung diseases. It is now well established that spp.

Article Synopsis
  • The study aimed to compare gene expression and bacterial coinfection profiles in asymptomatic and mildly symptomatic COVID-19 patients using RNA sequencing of nasal swabs.* -
  • Results showed that asymptomatic patients experienced changes in macroautophagy and cell cycle processes, while mildly symptomatic patients had modifications in RNA transport and upregulation of certain genes, though no link between the severity of disease and viral variants was established.* -
  • The findings suggest that issues in autophagy and RNA processing could affect disease progression, highlighting the importance of considering bacterial coinfections like Streptococcus pneumoniae in symptomatic patients.*

Klutuk Wulung banana ( Colla, BB Group) is a climacteric fruit whose ripening is influenced by ethylene production. This banana fruit has a relatively slow ripening process time and long shelf-life compared with A genome banana (, AA). Bananas are usually harvested at a pre-climacteric stage and ripened artificially by exogenous ethylene.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is responsible for coronavirus disease (COVID-19), potentially have severe kidney adverse effects. This organ expressed angiotensin-converting enzyme 2 (ACE2), the transmembrane protein which facilitate the entering of the virus into the cell. Therefore, early detection of the kidney manifestations of COVID-19 is crucial.

Banana ripening is a complex molecular process that produces visible changes in the texture, aroma, taste and nutritional content. Ripening is controlled by genetic code, metabolic pathway and associated microbiome. We reported the microbial community structure during banana ripening with alcohol treatment to discover endophytic and epiphytic microbes.
