Equine endometriosis is a multifactorial disease considered to be a major cause of equine infertility. The purpose of this study was to evaluate the reliability of histomorphological grading for biopsy-like samples compared to entire uterine wall samples, to examine the association between the degree of endometriosis with animal age, and to investigate the role of inflammation in endometriosis and the expression of different matrix metalloproteinases in equine endometrium. Histomorphological lesions in 35 uterine samples were examined while comparing biopsy-like samples and entire-wall samples. Seventeen uterine samples were stained with antibodies against MMP-2, MMP-9, MMP-14, and TIMP-2. The morphologic evaluation results of the biopsy-like tissue and entire-wall samples were significantly correlated. Endometriosis in older mares (>12 years of age) was more severe than in young mares (2∼4 years of age), confirming the positive correlation between animal age and disease severity, while inflammation was poorly related to the degree of endometriosis. MMP-2 and MMP-14 were detected in stromal cells, while MMP-9 and TIMP-2 were both found in stromal and glandular epithelial cells. There were no significant differences in MMPs expression between the two groups (young vs. old mares). Additional studies on the activity of MMPs could further define the role of these enzymes in equine endometriosis.

The use of social media has increased considerably in recent years. However, these tools are not always used consciously, and the stress that can result from their inappropriate use is often underestimated. Children, who tend to be heavy users of social media, are exposed to risks associated with their intensive use. Data on the consequences of social media on children’s health are extensive; however, few studies have examined the association between their use and functional gastrointestinal disorders (FGIDs). Our research showed that social media use is associated with adverse health outcomes such as stress, poor sleep quality, and gastrointestinal disorders in children and adolescents. FGIDs should be considered a group of biopsychosocial disorders involving gut dysfunction and psychological health. Stress may exacerbate the symptoms of these disorders and is associated with psychological comorbidities. Recent findings demonstrated a high prevalence of social media use and the incidence of psychological disorders, such as anxiety and depression, and decreased well-being in children with FGIDs. This review underlines that social media use is an emerging aspect of the psychosocial lives of children and adolescents; thus, it may be involved in FGID onset. Further studies in this field are needed to elucidate the link between social media and gastrointestinal health. Clinicians and politicians can play an important role in promoting the regulated and responsible use of digital platforms to protect the psychological health and preserve the well-being of children and adolescents.

Gene polymorphisms involved in homocysteine- methionine pathway result in hyperhomocysteinemia, a predisposing condition to several diseases. Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme in folate and homocysteine metabolism. The two known functional polymorphisms of MTHFR gene, 677C>T and 1298A>C have been implicated in a variety of multifactorial diseases: cardio-cerebrovascular and neurodegenerative disorders, autoimmune diseases, birth defects, diabetes, neuropsychiatric disorders, cancer and renal disease. C667T, and to a lesser extent A1298C polymorphisms, have been also reported to have a pharmacogenetic role in predicting drug toxicity in cancer and rheumatoid arthritis treatment. We review here the principal effects of the MTHFR gene variations in different clinical conditions.
Current status and outlook on the clinical translation of biodegradable metals

<P><B>Abstract</B></P> <P>During the last decade, translational research on biodegradable metallic materials has shown the feasibility of these novel materials for use in the fields of cardiology and orthopedics. Implants prepared with biodegradable metals are significantly stronger than their polymer counterparts, and there is now convincing evidence demonstrating that these materials fully biodegrade <I>in vivo</I>, thus reducing the need for secondary surgery. Clinical trials of such novel materials show significant potential, with the prospect of a paradigm shift in the way musculoskeletal and cardiovascular conditions are treated. This work provides an overview of the rapidly advancing technology of biodegradable metals, as well as defining some challenges in the application of these new biodegradable materials in the medical field.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

<P><B>Significance</B></P><P>Interleukin-1 family members are highly inflammatory but IL-37 member broadly suppresses inflammation and specific immunity. Initially, the mechanism of this suppression was shown to be via translocation to the nucleus following cleavage of the precursor by intracellular caspase-1. We now show that recombinant forms of IL-37 limit inflammation by extracellular binding to surface receptors but require the IL-1 family decoy receptor IL-1R8. Unexpectedly, picomolar concentrations of the IL-37 precursor optimally suppress IL-1β, IL-6, and TNFα production from human blood M1 macrophages, suggesting a unique function for a coreceptor function of IL-1R8. Assessment of IL-37 as well as IL-1R8 levels may provide previously unidentified insights into how the host limits inflammation.</P><P>Similar to IL-1α and IL-33, IL-1 family member IL-37b translocates to the nucleus and is associated with suppression of innate and adaptive immunity. Here we demonstrate an extracellular function of the IL-37 precursor and a processed form. Recombinant IL-37 precursor reduced LPS-induced IL-6 by 50% (<I>P</I> < 0.001) in highly inflammatory human blood-derived M1 differentiated macrophages derived from selective subjects but not M2 macrophages. In contrast, a neutralizing monoclonal anti–IL-37 increased LPS-induced IL-6, TNFα and IL-1β (<I>P</I> < 0.01). The suppression by IL-37 was consistently observed at low picomolar but not nanomolar concentrations. Whereas LPS induced a 12-fold increase in TNFα mRNA, IL-37 pretreatment decreased the expression to only 3-fold over background (<I>P</I> < 0.01). Mechanistically, LPS-induced p38 and pERK were reduced by IL-37. Recombinant IL-37 bound to the immobilized ligand binding α-chain of the IL-18 receptor as well as to the decoy receptor IL-1R8. In M1 macrophages, LPS increased the surface expression of IL-1R8. Compared with human blood monocytes, resting M1 cells express more surface IL-1R8 as well as total IL-1R8; there was a 16-fold increase in IL-1R8 mRNA levels when pretreated with IL-37. IL-37 reduced LPS-induced TNFα and IL-6 by 50–55% in mouse bone marrow-derived dendritic cells, but not in dendritic cells derived from IL-1R8–deficient mice. In mice subjected to systemic LPS-induced inflammation, pretreatment with IL-37 reduced circulating and organ cytokine levels. Thus, in addition to a nuclear function, IL-37 acts as an extracellular cytokine by binding to the IL-18 receptor but using the IL-1R8 for its anti-inflammatory properties.</P>

Coccoloba mollis (Family Polygonaceae) is a medicinal plant popularly used in cases of memory loss, stress, insomnia, anemia, impaired vision, and sexual impotence, but the scientific literature, to date, lacks studies on the biological effects of this species, particularly with regard to cytotoxicity and induction of DNA damage. The aim of the present study was to assess in vitro (in hepatic HTC cells) ethanolic extracts of the roots and leaves of C. mollis for cytotoxicity, genotoxicity, and induction of apoptosis. For these evaluations the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cytotoxicity assay, comet assay, micronucleus test with cytokinesis block, and an in situ test for detection of apoptotic cells with acridine orange staining were used. The results showed that the extract obtained from the roots of C. mollis is more cytotoxic than that obtained from the leaves and that the reduction in cell viability observed in the MTT assay was a result, at least in part, from the induction of apoptosis. Both extracts induced DNA damage at a concentration of 20μg/mL in the comet assay, but no genotoxicity was detected with any of the treatments carried out in the micronucleus test.
