Determination of collagen content within picrosirius red stained paraffin-embedded tissue sections using fluorescence microscopy

MethodsX, 2015
Picrosirius red (PSR) staining is a commonly used histological technique to visualize collagen in paraffin-embedded tissue sections. PSR stained collagen appears red in light microscopy.

Porphyromonas gingivalis GroEL exacerbates orthotopic allograft transplantation vasculopathy via impairment of endothelial cell function

Molecular Oral Microbiology, EarlyView.
Abstract Orthotopic allograft transplantation (OAT) is a significant approach to addressing organ failure. However, persistent immune responses to the allograft affect chronic rejection, which induces OAT vasculopathy (OATV) and organ failure. Porphyromonas gingivalis can infiltrate remote organs via the bloodstream, thereby intensifying the severity ...

Porphyromonas gingivalis GroEL accelerates abdominal aortic aneurysm formation by matrix metalloproteinase‐2 SUMOylation in vascular smooth muscle cells: A novel finding for the activation of MMP‐2

Molecular Oral Microbiology, EarlyView.
Abstract Infection is a known cause of abdominal aortic aneurysm (AAA), and matrix metalloproteases‐2 (MMP‐2) secreted by vascular smooth muscle cells (SMCs) plays a key role in the structural disruption of the middle layer of the arteries during AAA progression.

Picrosirius red e tricrômico de masson como ferramentas para detecção de fibras colágenas em pele de cães com dermatopatologias endócrinas [PDF]

, 2019
Canine endocrinopathies, such as hypothyroidism and hyperadrenocortism,induce typical dermatological alterations. Collagen fibers are significant for the maintenance of structural integrity,as well as in the determination of tissue function.

Effects of photobiomodulation therapy on pulmonary inflammation in chronic asthma: Dosimetric study in an experimental model

Photochemistry and Photobiology, EarlyView.
Photobiomodulation therapy (PBMT) was evaluated across a radiant energy range (1–7.5 J) in a murine model of chronic ovalbumin‐induced asthma to identify the optimal therapeutic dose. PBMT attenuated airway inflammation and remodelling, suppressed Th2 cytokines, and enhanced regulatory immune responses, highlighting a dose‐dependent immunomodulatory ...

Periodontitis and metabolic dysfunction‐associated steatotic liver disease

Periodontology 2000, EarlyView.
Abstract Objective Periodontitis is a chronic inflammatory disease with systemic effects that extend beyond the oral cavity and contribute to systemic immune and metabolic dysregulation. Chronic liver diseases, particularly metabolic dysfunction‐associated steatotic liver disease (MASLD) and its progressive phenotypes, have emerged as major global ...

mTOR blockade prevents progressive proteinuria but induces hyperglycaemia in obese Dahl salt‐sensitive rats before puberty

Experimental Physiology, EarlyView.
Abstract Previous studies have demonstrated that mammalian target of rapamycin (mTOR) activity is significantly increased in the kidneys of Dahl salt‐sensitive (SS) rats during the development of renal injury. Therefore, in the present study we examined whether blockade of mTOR with rapamycin inhibits renal injury in Dahl salt‐sensitive leptin receptor
