28-5.25) decline of eGFR during follow-up. In particular, DKK3 was associated with a significantly higher risk for declining eGFR in patients with eGFR over 90 ml/min/1.73m2 and proteinuria under 30 mg/g. DKK3 was also associated with declining COPD marker (2.90 1.70-4.68). The impact of DKK3 was further explored in wild-type and Dkk3-/- mice subjected to cigarette smoke-induced lung injury combined with a CKD model. In this model, genetic abrogation of DKK3 resulted in reduced pulmonary inflammation and preserved kidney function. Thus, our data highlight urinary DKK3 as a possible marker for early identification of patients with silent progressive CKD and for adverse outcomes in patients with COPD.The effect of GFAP-positive astrocytes, as positive or negative factors on stroke complications such as infarct volume and neurological deficits is currently under debate. This review was aimed to evaluate and compare the frequency of studies that showed a positive or negative relationship between astrocyte activation with the improvement of neurological deficits and/or the decrease of infarct volume. In addition, we reviewed two possible causes of differences in results including timepoint of stroke and stroke severity. Time of GFAP assessment was considered as time point and type of stroke induction and duration of stroke as stroke severity. According to our review in the most relevant English-language studies in the PubMed, Web of Science, and Google Scholar databases from 2005 to 2020, the majority of studies (77 vs. 28) showed a negative coincidence or correlation between GFAP-positive cells with neurological improvement as well as between GFAP-positive cells with infarct volume reduction. In most reviewed studies, GFAP expression was reported as a marker related to or coinciding with worse neurological function, or greater infarct volume. However, there were also studies that showed helpful effects of GFAP-positive cells on neurological function or stroke lesion. Although there are some elucidations that the difference in these findings is due to the time point of stroke and stroke severity, our review did not confirm these interpretations.Ageing is the biggest risk factor for impaired cardiovascular health, with cardiovascular disease being the cause of death in 40 % of individuals over 65 years old. Ageing is associated with an increased prevalence of atherosclerosis, coronary artery stenosis and subsequent myocardial infarction, thoracic aortic aneurysm, valvular heart disease and heart failure. An accumulation of senescence and increased inflammation, caused by the senescence-associated secretory phenotype, have been implicated in the aetiology and progression of these age-associated diseases. Recently it has been demonstrated that compounds targeting components of anti-apoptotic pathways expressed by senescent cells can preferentially induce senescence cells to apoptosis and have been termed senolytics. In this review, we discuss the evidence demonstrating that senescence contributes to cardiovascular disease, with a particular focus on studies that indicate the promise of senotherapy. Based on these data we suggest novel indications for senolytics as a treatment of cardiovascular diseases which have yet to be studied in the context of senotherapy. Finally, while the potential benefits are encouraging, several complications may result from senolytic treatment. We, therefore, consider these challenges in the context of the cardiovascular system.In acute ischemic stroke due to large vessel occlusion (LVO) infarcts rapidly grow into the penumbra, which represents dysfunctional, but still viable brain tissue amenable to rescue by vessel recanalization. However, infarct progression and/or delayed patient presentation are serious and frequent limitations of this so far only acute therapy. Thus, a major goal of translational research is to "freeze" the penumbra already during LVO (before opening the vessel) and thereby extend individual time windows for non-futile recanalization. We used the filament occlusion model of the middle cerebral artery (MCAO) in mice and assessed progressive infarction under occlusion at 2, 3, and 4 h after onset. We show that blocking the activatory platelet receptor glycoprotein (GP)VI substantially delayed progressive neocortical infarction compared to isotype control antibody treated mice. Moreover, the local vascular recruitment of infiltrating neutrophils and T-cells was mitigated. In conclusion, our experimental data support ongoing clinical trials blocking platelet GPVI in acute ischemic stroke.The funny current, and the HCN channels that form it, are affected by the direct binding of cyclic nucleotides. Binding of these second messengers causes a depolarizing shift of the activation curve, which leads to greater availability of current at physiological membrane voltages. This review outlines a brief history on this regulation and provides some evidence that other cyclic nucleotides, especially cGMP, may be important for the regulation of the funny channel in the heart. Current understanding of the molecular mechanism of cyclic nucleotide regulation is also presented, which includes the notions that full and partial agonism occur as a consequence of negatively cooperative binding. selleck Knowledge gaps, including a potential role of cyclic nucleotide-regulation of the funny current under pathophysiological conditions, are included. The work highlighted here is in dedication to Dario DiFrancesco on his retirement.Date palm (Phoenix dactylifera L.) is among the most ancient cultivated crops, of special value owing to its fruits high nutritive and economic benefits. Asides, date palm pollen is a high energy material that has been used traditionally used for fertility enhancement. In this study, effects of date palm pollen crude extract and its fractions viz., petroleum ether, methylene chloride, ethyl acetate and n-butanol on the female reproductive system were evaluated for the first time in relation to its metabolite fingerprint. Fertility activity was evaluated in immature female rats by assessing their FSH-, LH- and estrogen- activities. To pinpoint active hormonal agents in crude pollen extract and fractions, UPLC- MS analysis was employed for metabolites profiling, and in correlation to extract/fraction bioassays using multivariate OPLS analysis. Results revealed that both polar n-butanol and non-polar petroleum ether fractions exhibited the strongest activities; with a significant increase in FSH (25.7 mIU/ml in n-butanol group), estradiol (414.
