Rapid detection of the novel human pathogen Pantoea piersonii: advancements in methodology.

Pantoea piersonii a novel bacterium isolated from the International Space Station (ISS) presents a unique challenge for microbial monitoring in spaceflight and more recently in clinical environments. Identification of the organism currently involves culture, followed by whole genome sequencing and analysis of generated sequences. Since the MALDI-TOF profile of this pathogen is absent from the database and 16S rRNA sequencing fails to resolve its identity to the nearest neighbour, a definitive genetic marker is required for unambiguous identification of the organism.

Acute disseminated encephalomyelitis - a monophonic illness.

Acute Disseminated Encephalomyelitis (ADEM) is an autoimmune condition frequently caused by infections or immunisation activities and is characterised by inflammation and demyelination in the central nervous system (CNS). It primarily affects the brain and spinal cord, typically triggered by an immune response, and most often occurs in children but can also affect adults. The condition usually presents with a rapid onset of neurological symptoms and is considered a monophasic illness, meaning it generally occurs as a single episode.

Statistical analysis of the unique characteristics of secondary structures in proteins.

Protein folding is a complex process influenced by the primary sequence of amino acids. Early studies focused on understanding whether the specificity or the conservation of properties of amino acids was crucial for folding into secondary structures such as α-helices, β-sheets, turns, and coils. However, with the advent of artificial intelligence (AI) and machine learning (ML), the emphasis has shifted towards the precise nature and occurrence of specific amino acids.

Genomic analysis reveals the presence of emerging pathogenic lineages aboard the International Space Station.

The International Space Station (ISS) is a unique, hermetically sealed environment, subject to environmental pressures not encountered on Earth, including microgravity and radiation (cosmic ionising/UV).

Hydrophobicity─A Single Parameter for the Accurate Prediction of Disordered Regions in Proteins.

The prediction of disordered regions in proteins is crucial for understanding their functions, dynamics, and interactions. Intrinsically disordered proteins (IDPs) play a key role in many biological processes like cell signaling, recognition, and regulation, but experimentally determining these regions can be challenging due to their high mobility. To address this challenge, we present an algorithm called HydroDisPred (HDP).

Microbial Technologies in Waste Management, Energy Generation and Climate Change: Implications on Earth and Space.

Microbes are important decomposers of organic waste. By decomposing organic waste and using it for their growth, microbes play an important role in maintaining ecosystem's carbon and nitrogen cycles. An ecosystem's microbial shift may disturb it's carbon/nitrogen cycle as a result of any climate change or humanitarian factors, but heat produced by various instruments and greenhouse gases contribute significantly to global warming which in turn may be related to microbial shift of ecosystems.

Understanding the role of hydrophobic patches in protein disaggregation.

Protein folding is a very complex process and, so far, the mechanism of folding still intrigues the research community. Despite a large conformational space available (O(10) for a 100 amino acid residue), most proteins fold into their native state within a very short time. While small proteins fold relatively fast (a few microseconds) large globular proteins may take as long as several milliseconds to fold.
