3 years Soon after CARMENA: Exactly what Have We Realized?
In addition, blood ADRB2 5'-UTR methylation level significantly correlated with whole blood aluminum concentration in asthmatic children (r = 0.480, p less then 0.001). We concluded that increasing blood aluminum concentration is an important independent correlate of risk for uncontrolled bronchial asthma as well as increased blood aluminum concentration caused ADRB2 5'-UTR hyper-methylation with increasing risk of uncontrolled bronchial asthma.Aim To develop a strategy to improve response to bacillus Calmette-Gueri (BCG) using cytokine gene therapy (Gmcsf + Ifnα). Materials & methods MB49-PSA tumor-bearing C57BL/6N mice were assigned into four groups control; Gmcsf + Ifnα therapy; BCG therapy or combined therapy (Gmcsf + Ifnα and BCG). In schedule 1, cytokine gene therapy was delivered before BCG therapy (eight instillations). In schedule 2, cytokine gene and BCG therapy were instilled alternatively (eight instillations). Tumors were analyzed by immunohistochemistry and mRNA analysis and urinary immune cells by flow cytometry. Results Combined therapy in schedule 2 reduced tumor growth, increased immune cell recruitment and was associated with reduced inflammation when compared with BCG therapy. Conclusion Alternating cytokine gene delivery with BCG therapy modulates the tumor environment increasing receptivity to BCG.Background Complete regeneration after skin injury remains a critical clinical challenge. Hydrogels, modified with growth factors or mimicking peptides, have been applied for functional tissue regeneration by increasing the bioactivity of engineered matrices. Methodology & results We synthesized an injectable biological hydrogel, C domain of IGF-1 (IGF-1C)-modified chitosan (CS-IGF-1C) hydrogel. Mouse model of cutaneous wound healing was established to investigate whether this hydrogel could promote wound healing. Our results demonstrated that CS-IGF-1C hydrogel exhibited superior proangiogenic effects, resulting in accelerated wound closure and improved extracellular matrix remodeling. Bioluminescence imaging and histology analysis confirmed the proangiogenic role of CS-IGF-1C hydrogel. Conclusion CS-IGF-1C hydrogel could accelerate cutaneous wound healing by stimulating angiogenesis.Chronic obstructive pulmonary disease (COPD), characterized by chronic inflammation, is a recognized global health crisis. Sialic acid-binding immunoglobulin-like lectin 1 (siglec1 or CD169), mainly expressed in macrophages and dendritic cells, is markedly upregulated after encountering pathogens or under acute/chronic inflammation conditions. However, it is rarely reported that whether siglec1 plays a role in the development of COPD. In this study, we found that siglec1 had higher expression in the lungs from COPD rats and in peripheral blood mononuclear cells (PBMCs) from COPD patients. Knockdown of siglec1 in vivo and in vitro dramatically decreased pro-inflammatory cytokines production in pulmonary macrophages and alleviated pulmonary inflammatory responses in COPD rats as well as inactivated nuclear factor kappa B (NF-κB) signaling. In addition, we identified a new microRNA, miR-195-5p, which has never explored in COPD, was lower expressed in COPD rats and PBMC of COPD patients, and could negatively modulate siglec1 expression in macrophages. Moreover, overexpression of miR-195-5p via miR-195-5p mimics in vitro and in vivo could significantly alleviate pro-inflammatory cytokines production in pulmonary macrophages and pulmonary inflammatory responses in COPD rats. Together, our findings suggested that miR-195-5p inhibited the development of COPD via targeting siglec1, which might become a therapeutic target to improve COPD.BACKGROUND The present study was aimed to explore the effects and the underlying mechanism of prophylactic low-molecular-weight heparin (LMWH) treatment on taurocholate-induced severe acute pancreatitis (SAP) in a rat model. METHODS Rat SAP model was induced by injection of 4% sodium taurocholate into the pancreatic duct. LMWH was applied half an hour before the induction of pancreatitis at the dose of 200 IU/kg subcutaneous injection. The rats were euthanized at 1 h, 6 h, and 12 h after taurocholate-induced SAP. The inflammatory and oxidative response markers were assessed. And the vascular endothelial growth factor (VEGF) and Fms-related tyrosine kinase 1 (Flt-1) expression were evaluated by immunohistochemistry (IHC) and western blot methods. RESULTS The expression of inflammatory and oxidative response markers increased after induction of SAP. IHC and western blot results showed the VEGF and Flt-1 expression were increased in SAP group. Prophylactic LMWH administration reduced the inflammatory and oxidative response markers expression and decreased the expression of VEGF and Flt-1. CONCLUSIONS This study suggested that prophylactic LMWH treatment mitigated the severity of pancreatitis in rat SAP model by anti-inflammation and oxidative response. The underlying mechanism may result from downregulating VEGF/Flt-1 signaling of LMWH in SAP rat model.OBJECTIVE To explore and describe the experience of growing up with unilateral cleft lip and palate (CLP) in adults. DESIGN Face-to-face interviews. Giorgi's phenomenological method was used for analysis. PARTICIPANTS Twenty-one (mean age 40.8 years) adults treated for unilateral CLP during childhood and adolescence participated in the study. RESULTS Growing up with CLP meant to become aware of bodily otherness. The possible reactions from peers early in life complicated the striving for inclusion outside the close family. Being self-confident, clever in school, physically fit, and having trusted friends represented barriers against teasing and bullying. Nevertheless, the reflected image, in mirrors, windows, and photos, reminded the participants of the objectifying looks from others and often led to bodily adjustments that persisted into adulthood. The trajectory of treatment was not questioned during childhood, and the participants accepted the decisions on care made by experts and parents. Although problems related to the cleft could persist or return after the termination of ordinary treatment, a more hesitant view on the possible benefits of additional surgery was typical in adulthood. CONCLUSIONS In retrospect, growing up with a unilateral CLP was found to have been an unquestioned part of the adult participants' childhood, a burden that they feared would, to some extent, also be passed to their own children. However, the CLP had not prevented them from achieving goals and satisfaction in life. The occurrence of persisting psychological, functional, and esthetic challenges in adults suggests the need for an individualized, lifelong, and multidisciplinary perspective on CLP follow-up.A screening program for abdominal aortic aneurysm (AAA), inviting 65-year-old men, was started in Stockholm in 2010 (2.3 million inhabitants). The aim was to present a long-term follow-up of men participating in screening, as well as AAA repair and ruptures among nonparticipants. Demographics were collected for men with screening detected with AAA 2010 to 2016 (n = 672) and a control group with normal aortas at screening (controls, n = 237). Medical charts and regional Swedvasc (Swedish Vascular registry) data were analyzed for aortic repair for men born 1945 to 1951. Ultrasound maximum aortic diameter (AD) as well as Aortic Size Index (ASI) was recorded. Participation was 78% and prevalence of AAA was 1.2% (n = 672). Aortic repair rates correlated with high ASI and AD. During the study period, 22% of the AAA patients were treated with the elective repair; 35 men in surveillance died (5.2%), non-AAA-related causes (82.9%) dominated, followed by unknown causes among 4 (11.4%), and 2 (5.7%) possibly AAA-related deaths. Abdominal aortic aneurysm rupture rate was higher among nonparticipants (0.096% vs 0.0036%, P less then .001). The low dropout rate confirms acceptability of follow-up after screening. The efficacy is shown by the much higher rupture rate among the nonparticipating men.Background Significant improvements in myocardial structure and function have been reported in some advanced heart failure (HF) patients (termed Responders-R) following left ventricular assist device (LVAD)-induced mechanical unloading. This therapeutic strategy may alter myocardial energy metabolism in a manner that reverses the deleterious metabolic adaptations of the failing heart. Specifically, our prior work demonstrated a post-LVAD dissociation of glycolysis and oxidative-phosphorylation characterized by induction of glycolysis without subsequent increase in pyruvate oxidation via the TCA cycle. Selleck Kinase Inhibitor Library The underlying mechanisms responsible for this dissociation are not well understood. We hypothesized that the accumulated glycolytic intermediates are channeled into cardioprotective and repair pathways, such as the pentose-phosphate pathway and one-carbon metabolism, which may mediate myocardial recovery in Responders. Methods We prospectively obtained paired LV apical myocardial tissue from non-failing donor htic metabolites into pentose-phosphate pathway and one-carbon metabolism which could contribute to cardioprotection by generating NADPH to enhance biosynthesis and by reducing oxidative stress. These findings provide further insights into mechanisms responsible for the beneficial impact of glycolysis induction during the recovery of failing human hearts following mechanical unloading.Coronavirus disease 19 (COVID-19) originated in Wuhan, China, in December 2019 has been declared pandemic by World Health Organization due to an exponential rise in the number of infected and deceased persons across the globe. Emerging reports suggest that susceptibility and mortality rates are higher in patients with certain comorbidities when compared to the average population. Cardiovascular diseases and diabetes are important risk factors for a lethal outcome of COVID-19. Extensive research ensuing the outbreak of coronavirus-related severe acute respiratory syndrome in the year 2003, and COVID-19 recently revealed a role of renin-angiotensin system (RAS) components in the entry of coronavirus wherein angiotensin-converting enzyme 2 (ACE2) had garnered the significant attention. This raises the question whether the use of RAS inhibitors, the backbone of treatment of cardiovascular, neurovascular, and kidney diseases could increase the susceptibility for coronavirus infection or unfortunate outcomes of COVID-19. Thus, currently, there is a lack of consensus regarding the effects of RAS inhibitors in such patients. Moreover, expert bodies like American Heart Association, American College of Cardiology, and so on have now released official statements that RAS inhibitors must be continued, unless suggested otherwise by a physician. In this brief review, we will elaborate on the role of RAS and ACE2 in pathogenesis of COVID-19. Moreover, we will discuss the potential effect of the use and disuse of RAS inhibitors in patients having COVID-19 with cardiometabolic comorbidities.The prevention and treatment of mental health disorders in childhood and adolescence is one among the major public health challenges in the United States today. Prior research has suggested that neighborhood is very important for children and adolescents' mental health. The present study extends the research on neighborhood and mental health by examining the association between childhood mental health and the identified specific built environment attributes in neighborhood as well as its intersection with race/ethnicity in the United States. Statistical analyses results of data from the 2016 National Survey of Children Health (NSCH) indicate that children's mental health and the built environment in neighborhood vary across racial/ethnic groups, with minority groups being more likely to live in the disadvantaged neighborhoods and to experience more mental health disorders, particularly American Indian children. Further, the relationship between built environment neighborhood mental health among children varies across race/ethnicity in the United States.
