Francesco Mariani, Luca Roncucci
The presence of chronic inflammation in the colonic mucosa leads to an increased risk of cancer. Among proteins involved in the regulation of mucosal inflammation and that may contribute both to structural damage of the intestinal mucosa and to intestinal carcinogenesis, there are myeloperoxidase (MPO) and vanins. The infiltration of colonic mucosa by neutrophils may promote carcinogenesis through MPO, a key enzyme contained in the lysosomes of neutrophils that regulates local inflammation and the generation of reactive oxygen species (ROS) and mutagenic species...

The acute respiratory distress syndrome (ARDS) is typically manifested by refractory hypoxemia with high mortality. A correct diagnosis is the first step to achieve better outcomes. An early intervention to manage modifiable risk factors of ARDS development and the avoidance of aggravating factors that increase disease severity and progression should be carefully addressed. A management plan is necessary at an early stage of ARDS to determine the level of intensive care. It should be carefully decided which therapeutic measures should be performed depending on the patient׳s underlying clinical condition...

The persistent inflammation and oxidative stress at the local site in ulcerative colitis reportedly extend to the testes via systemic circulation resulting in testicular dysfunction. The influence of 6-gingerol (6G), a phenolic compound isolated from Zingiber officinale, on colitis-mediated testicular dysfunction in mice was investigated in this study. Chronic ulcerative colitis was induced in mice using 2.5% dextran sulfate sodium (DSS) in drinking water for three cycles. Each cycle consisted of 7 consecutive days of exposure to DSS-treated water followed by 14 consecutive days of normal drinking water...

The healing of chronic wounds requires intensive medical intervention at huge healthcare costs. Dressing materials should consider the multifactorial nature of these wounds comprising deleterious proteolytic and oxidative enzymes and high bacterial load. In this work, multifunctional hydrogels for chronic wound application were produced by enzymatic cross-linking of thiolated chitosan and gallic acid. The hydrogels combine several beneficial to wound healing properties, controlling the matrix metalloproteinases (MMPs) and myeloperoxidase (MPO) activities, oxidative stress, and bacterial contamination...

Stress, including both psychological and physical stimulation, can cause changes in the microbiota and mucosal function of the gastrointestinal system. There are few research studies available about the faecal microbiota changes after stress, such as water immersion restraint stress (WIRS). Therefore, in this study, we focused on analysing the composition changes of faecal microbiota in WIRS mice. The WIRS model, in which Blab/c mice were immersed in 21 ± 2 °C water for 4 h each day for 14 days, was established...

18β-Glycyrrhetinic acid (18Gly), the major bioactive component of Glycyrrhizae Radix, possesses anti-ulcerative, anti-inflammatory, and other pharmacological properties. Although 18Gly is associated with immunoregulatory functions of allergic diseases, the pathophysiological mechanisms of 18Gly action in allergic inflammatory lung disease have not been examined. Moreover, there are no in vivo studies on the anti-asthmatic effects of 18Gly in allergic asthma. We investigated its effect and mechanism of action in airway inflammation in a BALB/c mouse model of allergic asthma...

Abomasal ulcers lead to several problems. They cause pain resulting in a decrease in productivity and even the possible loss of the animal. Because they are frequently difficult to diagnose, information on their prevalence is variable. Additionally, therapeutic options are limited. Abomasal ulcers are graded as type 1 through 4, type 1 being a superficial defect and type 2 an ulcer where a large blood vessel has been eroded, leading to substantial blood loss. Types 3 and 4 are perforated abomasal ulcers leading to local and diffuse peritonitis, respectively...
