Article Abstract
The recent outbreaks of Marburg virus disease (MVD) in Guinea, Ghana, Equatorial Guinea, and Tanzania, none of which had reported previous outbreaks, imply increasing risks of spillover of the causative viruses, Marburg virus (MARV) and Ravn virus (RAVV), from their natural host animals. These outbreaks have emphasized the need for the development of rapid diagnostic tests for this disease. Using monoclonal antibodies specific to the viral nucleoprotein, we developed an immunochromatography (IC) assay for the rapid diagnosis of MVD. The IC assay was found to be capable of detecting approximately 10 50% tissue culture infectious dose (TCID)/test of MARV and RAVV in the infected culture supernatants. We further confirmed that the IC assay could detect the MARV and RAVV antigens in the serum samples from experimentally infected nonhuman primates. These results indicate that the IC assay to detect MARV can be a useful tool for the rapid point-of-care diagnosis of MVD.

This study introduces a new, highly sensitive, and reliable method for detecting and measuring orthophosphate in environmental water samples. This method combines cetyltrimethylammonium bromide (CTAB)-mediated coacervation extraction with digital image-based colorimetry, providing a robust and efficient approach for orthophosphate analysis. In this system, CTAB, a cationic surfactant, serves a dual role as both an ion-pairing agent and an extraction medium.

Objective: This study investigated the relationship of maternal serum uric acid, cystatin C (CysC), and coagulation indices [international normalized ratio (INR) and fibrinogen (FIB)] during pregnancy with clinical features and prognosis of early-onset pre-eclampsia.
Methods: Patients with pre-eclampsia (n = 133) were retrospectively selected, with clinical features and maternal uric acid, CysC, INR, and FIB levels collected. The relationship between clinical features and maternal uric acid, CysC, INR, and FIB was analyzed by Pearson's and Spearman's analyses.

Chronic kidney disease (CKD), heart failure (HF) and atherosclerotic cardiovascular disease (ASCVD) are pathologies that may remain silent for a long time and thus are largely underdiagnosed in clinical practice. The use of biomarkers may help detect people already suffering from these diseases at an early stage or at increased risk to develop them in a near future. The aim of this article is to discuss the place of the assays of albuminuria, natriuretic peptide (BNP/proBNP) and high-sensitivity troponin as well as lipoprotein(a) to help in the diagnosis and prognosis assessment of individuals at risk of presenting or developing a CKD, HF or ASCVD.

Type 1 diabetes (T1D) is an autoimmune chronic disease that leads to the destruction of pancreatic beta cells and thus requires lifelong insulin therapy. Constraints and adverse events associated to insulin therapy are well known as well as the risk of long-term complications linked to chronic hyperglycaemia. Symptomatic T1D is preceded by a preclinical asymptomatic period, which is characterized by the presence of at least two auto-antibodies against beta cell without disturbances of blood glucose control (stage 1) or, in addition to immunological biomarkers, by the presence of mild dysglycaemia reflecting a defect of early insulin secretion (stage 2).

Oral cancer is a major global health burden, ranking sixth in prevalence, with oral squamous cell carcinoma (OSCC) being the most common type. Importantly, OSCC is often diagnosed at late stages, underscoring the need for innovative methods for early detection. The oral microbiome, an active microbial community within the oral cavity, holds promise as a biomarker for the prediction and progression of cancer.
