Bee sting envenomation severe cases in Manaus, Brazilian Amazon: clinical characteristics and immune markers of case reports

open access: yesRevista da Sociedade Brasileira de Medicina Tropical, 2020
Bee venom is a natural toxin composed of several peptides. Massive envenoming causes severe local and systemic reactions. We report two cases of severe bee envenomation, of which one was fatal. We also describe clinical characteristics and immune markers.

Assessment of cell-free DNA for early detection of ovarian cancer in women [PDF]

open access: yesJournal of Bioscience and Applied Research, 2019
Objectives: To assess circulating cell-free DNA’s diagnostic potential in Egyptian women with ovarian cancer. Background: Ovarian cancer (OC), one of the most common cancers worldwide, is the most lethal form of gynecological cancer, but the early ...

Clinical application of exosomes and circulating microRNAs in the diagnosis of pregnancy complications and foetal abnormalities

open access: yesJournal of Translational Medicine, 2020
During pregnancy in humans, the physiology of the mother and foetus are finely regulated by many factors. Inappropriate regulation can result in pregnancy disorders, such as complications and foetal abnormalities.

Apoptosis-related deregulation of proteolytic activities and high serum levels of circulating nucleosomes and DNA in blood correlate with breast cancer progression

open access: yesBMC Cancer, 2011
Background As cell-free circulating DNA exists predominantly as mono- and oligonucleosomes, the focus of the current study was to examine the interplay of circulating nucleosomes, DNA, proteases and caspases in blood of patients with benign and malignant

Current challenges and best practices for cell-free long RNA biomarker discovery

open access: yesBiomarker Research, 2022
The analysis of biomarkers in biological fluids, also known as liquid biopsies, is seen with great potential to diagnose complex diseases such as cancer with a high sensitivity and minimal invasiveness. Although it can target any biomolecule, most liquid

Circulating mitochondrial DNA is an early indicator of severe illness and mortality from COVID-19

open access: yesJCI Insight, 2021
Background Mitochondrial DNA (MT-DNA) are intrinsically inflammatory nucleic acids released by damaged solid organs. Whether circulating cell-free MT-DNA quantitation could be used to predict the risk of poor COVID-19 outcomes remains undetermined ...

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

open access: yesFEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.

Peripheral Blood-Based Biopsy for Breast Cancer Risk Prediction and Early Detection

open access: yesFrontiers in Medicine, 2020
Among women, breast cancer (BC) is not only the most common cancer worldwide but also the leading cause of cancer death. Only 5–10% of breast cancer cases are attributed to inherited mutations (BRCA1, BRCA2, and other breast cancer susceptibility genes).

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Recent advances in liquid biopsy in cancers: Diagnosis, disease state and treatment response monitoring

open access: yesClinical and Translational Discovery, 2022
Recent years have witnessed the development of scientific research and clinical trials of liquid biopsy in various diseases, especially cancers. Liquid biopsy refers to a procedure in which components, including circulating tumour cells (CTCs), cell‐free
