Understanding the consequences of Female Genital Mutilation: a phenomenological study in sub-Saharan women living in Spain.

Background: Female Genital Mutilation (FGM), which is culturally accepted in some African communities, has serious consequences on the physical, psychological, urogynecological, obstetrical and sexual health of girls and women. It is therefore important to understand women's experiences of the consequences of FGM.

Objective: to understand the experiences of the consequences of female genital mutilation in sub-Saharan female survivors living in Spain.

Effects of Plyometric, Strength and Change of Direction Training on High-School Basketball Player's Physical Fitness.

The study aim was to compare the effects of a 7-week plyometric, strength and change of direction (COD) training program on basketball-specific performance measures in high-school players. Forty male players were randomly assigned to one of the four groups: plyometric (PG, n = 10), strength (SG, n = 10), COD (CODG, n = 10), and control group training (CG, n = 10). Two training sessions were performed at weekly intervals before basketball training.

Downregulation of CFIm25 amplifies dermal fibrosis through alternative polyadenylation.

Systemic sclerosis (SSc; scleroderma) is a multisystem fibrotic disease. The mammalian cleavage factor I 25-kD subunit (CFIm25; encoded by NUDT21) is a key regulator of alternative polyadenylation, and its depletion causes predominantly 3'UTR shortening through loss of stimulation of distal polyadenylation sites. A shortened 3'UTR will often lack microRNA target sites, resulting in increased mRNA translation due to evasion of microRNA-mediated repression.

Adenosine and hyaluronan promote lung fibrosis and pulmonary hypertension in combined pulmonary fibrosis and emphysema.

Combined pulmonary fibrosis and emphysema (CPFE) is a syndrome that predominantly affects male smokers or ex-smokers and it has a mortality rate of 55% and a median survival of 5 years. Pulmonary hypertension (PH) is a frequently fatal complication of CPFE. Despite this dismal prognosis, no curative therapies exist for patients with CPFE outside of lung transplantation and no therapies are recommended to treat PH.

Cleavage factor 25 deregulation contributes to pulmonary fibrosis through alternative polyadenylation.

Idiopathic pulmonary fibrosis (IPF) is a chronic and deadly disease with a poor prognosis and few treatment options. Pathological remodeling of the extracellular matrix (ECM) by myofibroblasts is a key factor that drives disease pathogenesis, although the underlying mechanisms remain unknown. Alternative polyadenylation (APA) has recently been shown to play a major role in cellular responses to stress by driving the expression of fibrotic factors and ECMs through altering microRNA sensitivity, but a connection to IPF has not been established.

The Antifibrotic Effect of A Adenosine Receptor Antagonism in a Mouse Model of Dermal Fibrosis.

Objective: Systemic sclerosis (SSc; scleroderma) is a chronic disease that affects the skin and various internal organs. Dermal fibrosis is a major component of this disease. The mechanisms that promote dermal fibrosis remain elusive.

HIF1A up-regulates the ADORA2B receptor on alternatively activated macrophages and contributes to pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a deadly chronic lung disease. Extracellular accumulation of adenosine and subsequent activation of the ADORA2B receptor play important roles in regulating inflammation and fibrosis in IPF. Additionally, alternatively activated macrophages (AAMs) expressing ADORA2B have been implicated in mediating adenosine's effects in IPF.

Inhibition of hyaluronan synthesis attenuates pulmonary hypertension associated with lung fibrosis.

Background And Purpose: Group III pulmonary hypertension (PH) is a highly lethal and widespread lung disorder that is a common complication in idiopathic pulmonary fibrosis (IPF) where it is considered to be the single most significant predictor of mortality. While increased levels of hyaluronan have been observed in IPF patients, hyaluronan-mediated vascular remodelling and the hyaluronan-mediated mechanisms promoting PH associated with IPF are not fully understood.

Experimental Approach: Explanted lung tissue from patients with IPF with and without a diagnosis of PH was used to identify increased levels of hyaluronan.

Resetting microbiota by Lactobacillus reuteri inhibits T reg deficiency-induced autoimmunity via adenosine A2A receptors.

Regulatory T (T reg) cell deficiency causes lethal, CD4 T cell-driven autoimmune diseases. Stem cell transplantation is used to treat these diseases, but this procedure is limited by the availability of a suitable donor. The intestinal microbiota drives host immune homeostasis by regulating the differentiation and expansion of T reg, Th1, and Th2 cells.

Macrophage bone morphogenic protein receptor 2 depletion in idiopathic pulmonary fibrosis and Group III pulmonary hypertension.

Idiopathic pulmonary fibrosis (IPF) is a lethal lung disease of unknown etiology. The development of pulmonary hypertension (PH) is considered the single most significant predictor of mortality in patients with chronic lung diseases. The processes that govern the progression and development of fibroproliferative and vascular lesions in IPF are not fully understood.

Loss of CD73-mediated actin polymerization promotes endometrial tumor progression.

Ecto-5'-nucleotidase (CD73) is central to the generation of extracellular adenosine. Previous studies have highlighted a detrimental role for extracellular adenosine in cancer, as it dampens T cell-mediated immune responses. Here, we determined that, in contrast to other cancers, CD73 is markedly downregulated in poorly differentiated and advanced-stage endometrial carcinoma compared with levels in normal endometrium and low-grade tumors.

Extracellular adenosine levels are associated with the progression and exacerbation of pulmonary fibrosis.

Idiopathic pulmonary fibrosis is a devastating lung disease with limited treatment options. The signaling molecule adenosine is produced in response to injury and serves a protective role in early stages of injury and is detrimental during chronic stages of disease such as seen in lung conditions such as pulmonary fibrosis. Understanding the association of extracellular adenosine levels and the progression of pulmonary fibrosis is critical for designing adenosine based approaches to treat pulmonary fibrosis.

Elevated adenosine signaling via adenosine A2B receptor induces normal and sickle erythrocyte sphingosine kinase 1 activity.

Erythrocyte possesses high sphingosine kinase 1 (SphK1) activity and is the major cell type supplying plasma sphingosine-1-phosphate, a signaling lipid regulating multiple physiological and pathological functions. Recent studies revealed that erythrocyte SphK1 activity is upregulated in sickle cell disease (SCD) and contributes to sickling and disease progression. However, how erythrocyte SphK1 activity is regulated remains unknown.

Deletion of ADORA2B from myeloid cells dampens lung fibrosis and pulmonary hypertension.

Idiopathic pulmonary fibrosis (IPF) is a lethal, fibroproliferative disease. Pulmonary hypertension (PH) can develop secondary to IPF and increase mortality. Alternatively, activated macrophages (AAMs) contribute to the pathogenesis of both IPF and PH.

Adenosine A2B receptor and hyaluronan modulate pulmonary hypertension associated with chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death worldwide. The development of pulmonary hypertension (PH) in patients with COPD is strongly associated with increased mortality. Chronic inflammation and changes to the lung extracellular matrix (ECM) have been implicated in the pathogenesis of COPD, yet the mechanisms that lead to PH secondary to COPD remain unknown.

Hypoxia-induced deoxycytidine kinase expression contributes to apoptosis in chronic lung disease.

Chronic obstructive pulmonary disease (COPD) is characterized by persistent inflammation and tissue remodeling and is a leading cause of death in the United States. Increased apoptosis of pulmonary epithelial cells is thought to play a role in COPD development and progression. Identification of signaling pathways resulting in increased apoptosis in COPD can be used in the development of novel therapeutic interventions.

Interleukin-6 contributes to inflammation and remodeling in a model of adenosine mediated lung injury.

Background: Chronic lung diseases are the third leading cause of death in the United States due in part to an incomplete understanding of pathways that govern the progressive tissue remodeling that occurs in these disorders. Adenosine is elevated in the lungs of animal models and humans with chronic lung disease where it promotes air-space destruction and fibrosis. Adenosine signaling increases the production of the pro-fibrotic cytokine interleukin-6 (IL-6).

Adenosine and osteopontin contribute to the development of chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is a major health concern. Adenosine, a signaling molecule generated in response to cell stress, contributes to the pathogenesis of COPD. An established model of adenosine-mediated lung injury is the adenosine deaminase-deficient (Ada(-/-)) mouse.

Enhanced airway inflammation and remodeling in adenosine deaminase-deficient mice lacking the A2B adenosine receptor.

Adenosine is a signaling nucleoside that is generated in response to cellular injury and orchestrates the balance between tissue protection and the progression to pathological tissue remodeling. Adenosine deaminase (ADA)-deficient mice develop progressive airway inflammation and remodeling in association with adenosine elevations, suggesting that adenosine can promote features of chronic lung disease. Furthermore, pharmacological studies in ADA-deficient mice demonstrate that A(2B)R antagonism can attenuate features of chronic lung disease, implicating this receptor in the progression of chronic lung disease.

A3 adenosine receptor signaling influences pulmonary inflammation and fibrosis.

Adenosine is a signaling molecule produced during conditions that cause cellular stress or damage. This signaling pathway is implicated in the regulation of pulmonary disorders through the selective engagement of adenosine receptors. The goal of this study was to examine the involvement of the A(3) adenosine receptor (A(3)R) in a bleomycin model of pulmonary inflammation and fibrosis.

Excess adenosine in murine penile erectile tissues contributes to priapism via A2B adenosine receptor signaling.

Priapism, abnormally prolonged penile erection in the absence of sexual excitation, is associated with ischemia-mediated erectile tissue damage and subsequent erectile dysfunction. It is common among males with sickle cell disease (SCD), and SCD transgenic mice are an accepted model of the disorder. Current strategies to manage priapism suffer from a poor fundamental understanding of the molecular mechanisms underlying the disorder.

Enhanced CXCL1 production and angiogenesis in adenosine-mediated lung disease.

Angiogenesis is a feature of chronic lung diseases such as asthma and pulmonary fibrosis; however, the pathways controlling pathological angiogenesis during lung disease are not completely understood. Adenosine is a signaling molecule that has been implicated in the exacerbation of chronic lung disease and in the regulation of angiogenesis; however, the relationship between these factors has not been investigated. The current study utilized adenosine deaminase (ADA)-deficient mice to determine whether chronic elevations in adenosine in vivo result in pulmonary angiogenesis.

Role of A2B adenosine receptor signaling in adenosine-dependent pulmonary inflammation and injury.

Adenosine has been implicated in the pathogenesis of chronic lung diseases such as asthma and chronic obstructive pulmonary disease. In vitro studies suggest that activation of the A2B adenosine receptor (A2BAR) results in proinflammatory and profibrotic effects relevant to the progression of lung diseases; however, in vivo data supporting these observations are lacking. Adenosine deaminase-deficient (ADA-deficient) mice develop pulmonary inflammation and injury that are dependent on increased lung adenosine levels.

Effects of adenosine deaminase and A1 receptor deficiency in normoxic and ischaemic mouse hearts.

Objective: Adenosine deaminase (ADA) may be multifunctional, regulating adenosine levels and adenosine receptor (AR) agonism, and potentially modifying AR functionality. Herein we assess effects of ADA (and A1AR) deficiency on AR-mediated responses and ischaemic tolerance.

Methods: Normoxic function and responses to 20 or 25 min ischaemia and 45 min reperfusion were studied in isolated hearts from wild-type mice and from mice deficient in ADA and/or A1ARs.

Adenosine-dependent pulmonary fibrosis in adenosine deaminase-deficient mice.

Pulmonary fibrosis is a common feature of numerous lung disorders, including interstitial lung diseases, asthma, and chronic obstructive pulmonary disease. Despite the prevalence of pulmonary fibrosis, the molecular mechanisms governing inflammatory and fibroproliferative aspects of the disorder are not clear. Adenosine is a purine-signaling nucleoside that is generated in excess during cellular stress and damage.
