20-Hydroxyecdysone (20-HE) is known as the insect moulting hormone. It is part of the ecdysteroids family. Combined with the juvenile hormone (JH), 20-HE plays a key role in the growth, development, metamorphosis, and reproduction of arthropods (i.e. invertebrates such as insects, crustaceans, arachnids, etc.). Little is known about the function of ecdysteroids in vertebrates. There […]

Stem cells can develop into multiple cell types through a process called differentiation. The cellular form of prion protein (PrPC) has been reported to be involved in various cellular pathways and could also have a role in the differentiation of stem cells into neurons. Several studies have shown that the prion protein PrPC may be […]

Irritable bowel syndrome (IBS) is a common condition arising from genetic and environmental factors. It is characterized by a group of symptoms affecting the digestive system, including abdominal discomfort and altered bowel movements. Little is known about the environmental triggers for IBS. The symptoms might result from an altered immune response. Aluminum is a common […]

Endocrine disruptors (EDCs) in the environment come from several origins. When they accumulate in organisms, they can lead to endocrine system dysfunctions and consequently to population decline. One such disruptor is the insecticide chlordecone (CLD). Although EDC biomarkers are well established in vertebrates, few are available in invertebrates, such as arthropods. In this application note, […]

Chronic Wasting Disease (CWD) is a fatal prion disease affecting cervids. It is one of the only spongiform encephalopathy that is environmentally transmitted. CWD prions are released into the environment either through carcasses or through biological fluids. Soils have been reported to play a major role in horizontal CWD transmission, however little is known about […]

Histamine is a molecule that plays a major role in local immune responses and acts as a neurotransmitter for the brain, spinal cord, and uterus. An increase in local histamine levels can lead capillaries to become more permeable to leucocytes and some proteins, enabling them to attack pathogens in infected tissues. Following its discovery in […]

Bertin’s field application scientist Mariana Gaboriau has prepared a selection of articles dedicated to emulsion preparation using Precellys tissue homogenizers and the Precellys emulsion kit. A research article on the standardization of antigen-emulsion preparations for the induction of autoimmune disease models: experimental autoimmune encephalitis, collagen II induced arthritis, antigen induced arthritis, and delayed type hypersensitivity […]

Hypertension, also known as high blood pressure, is one of the leading causes of global cardiovascular mortality. If left untreated, high blood pressure can lead to several pathologic changes in the cardiovascular system such as left ventricular hypertrophy and fibrosis. Angiotensin-converting enzyme inhibitors (ACEi) are a key component of the recommended treatment for hypertension and […]

DNA or RNA extractions are routine techniques in many molecular biology laboratories. In these 2 new Application Notes, we present the results obtained using the Precellys Tissue DNA Extraction Kit & the Precellys Tissue Total RNA Extraction Kit with the Precellys 24 Touch tissue homogenizer and how they compare to some of our competitors. Read […]
