Abstract Early diagnosis of leptospirosis is critical for timely treatment and effective disease management. This study evaluated the diagnostic performance of a novel electrochemical aptasensor targeting the electron transfer flavoprotein subunit beta (EtfB) of Leptospira interrogans in clinical samples collected during the acute phase of leptospirosis. The aptasensor assay was tested using plasma samples and […]

Abstract Dengue is an important tropical disease with considerable global impact. Despite this, there remains an urgent need for reliable biomarkers to predict disease severity, as well as effective antiviral drugs and targeted treatments. In this study, we conducted a comprehensive profiling of 41 plasma mediators in patients with asymptomatic dengue (AD) and symptomatic dengue […]

Abstract Cellular protein homeostasis relies on a complex network of protein synthesis, folding, sub-cellular localization, and degradation to sustain a functional proteome. Since most of these processes are energy-driven, proteostasis is inescapably afflicted by cellular metabolism. Proteostasis collapse and metabolic imbalance are both linked to aging and age-associated disorders, yet they have traditionally been studied […]

Abstract Vibrio parahaemolyticus (VP) is a major bacterial species that causes early mortality syndrome (EMS) in shrimps. EMS can be classified into two groups based on histological signs of hepatopancreatic tissues, i.e., acute hepatopancreatic necrosis disease (AHPND) and non-AHPND. To investigate how toxin-producing AHPND and toxin-lacking non-AHPND VP could lead to EMS, growth characteristics and […]

Abstract Candida auris, one of the emerging multidrug-resistant Candida species, was first discovered in 2009 from the ear canal of a patient in Tokyo, Japan. Since then, several studies exhibit the possible threats of C. auris due to its versatile resistance to frontline antifungal agents. The number of studies focusing on genetic variants associated with […]

Abstract Leber’s hereditary optic neuropathy (LHON) is a maternally inherited disorder caused by mitochondrial DNA mutations in complex I of the respiratory chain, leading to impaired ATP production, mitochondrial fragmentation, and oxidative stress that contribute to vision loss. This study investigated the potential repurposing of metformin, a widely used antidiabetic drug, in fibroblasts from LHON […]

Abstract The starch and protein in rice grains determine their nutritional value, eating and cooking quality (ECQ), and potential applications as a biopolymer. Building on previously identified functional differences between two Thai indica cultivars, waxy RD6 and high-amylose RD57, we examined the transcriptional regulation of their storage polymers by profiling key starch-biosynthetic and storage-protein genes […]

Abstract Conventional mass spectrometry imaging (MSI), even when combined with low-resolution ion mobility, lacks the resolving power to distinguish stereoisomers. To address this limitation, we developed a high-resolution desorption electrospray ionization cyclic ion mobility mass spectrometry (DESI-cIM-MS) method for in situ separation and spatial mapping of stereoisomeric compounds, using Mitragyna speciosa (kratom) as a model […]
