The body lipid content ranged from 0.22 ± 0.06 to 0.87 ± 0.07 mg and was negatively associated with the WLR. This association indicates that the increase in internal metabolic water was mediated by lipid catabolism. Stable isotope analysis results revealed that the Paederus beetles shifted their diet to carbohydrate-rich plants when the saturation deficit increased and the associated WLR reached its peak; otherwise, they consumed a high amount of staple carbohydrate-poor herbivore prey. The accumulation of energy reserves in the form of lipids through seasonal dietary shifts may exert major effects on the survival and population success of mesic-adapted Paederus beetles.Spiders of the genus Dysdera are peculiar for their preying on terrestrial isopods though the preference for this prey type varies between species. We tested prey acceptance of two isopod and two non-isopod prey in 8 species endemic to the Canary Islands, and analyzed growth and metabolic parameters (growth efficiency; dry mass, lipid and N extraction efficiency; lipidprotein consumption ratio) of 6 of these species when fed either house flies (Musca domestica) or isopods (Porcellio scaber) in the laboratory. The species represented four morphological types (unmodified chelicerae, slightly elongated chelicerae, concave chelicerae, flattened fang), supposedly reflecting different specializations to isopod prey. The results showed reduced relative acceptance of non-isopod and increased acceptance of isopod prey in species groups with specialised morphologies compared to the unmodified species group. All species had similar or lower growth and growth efficiency when feeding on isopods than on flies. Extraction efficiency of dry mass and lipid were higher for flies than for isopods, while extraction efficiency of protein was higher for isopods than for flies. All species also utilized isopod protein equally well, but protein utilization of flies was lower in the presumed specialist compared to generalist species, indicating a possible metabolic trade-off from isopod specialisation. Thus, morphological adaptations were associated with increased behavioural preferences for isopods and reduced metabolic ability to handle 'generalist' prey.NADPH oxidase (Nox) mediates ROS production and contributes to cardiac remodeling. However, macrophage p47phox, a Nox subunit regulating cardiac remodeling, is unclear. We aimed to investigate the role of macrophage p47phox in hypertensive cardiac remodeling. Pressure-overload induced by Angiotensin II (AngII) for two weeks in young adult male p47phox deficient (KO) mice showed aggravated cardiac dysfunction and hypertrophy as indicated from echocardiographic and histological studies in comparison with wild-type littermates (WT). Additionally, LV of AngII-infused KO mice showed augmented interstitial fibrosis, collagen deposition and, myofibroblasts compared to AngII-infused WT mice. Moreover, these changes in AngII-infused KO mice correlated well with the gene analysis of hypertrophic and fibrotic markers. Similar results were also found in the transverse aortic constriction model. Further, AngII-infused KO mice showed elevated circulating immunokines and increased LV leukocytes infiltration and CD206+ macrophages compared to AngII-infused WT mice. Likewise, LV of AngII-infused KO mice showed upregulated mRNA expression of anti-inflammatory/pro-fibrotic M2 macrophage markers (Ym1, Arg-1) compared to AngII-infused WT mice. G150 AngII and IL-4 treated bone marrow-derived macrophages (BMDMs) from KO mice showed upregulated M2 macrophage markers and STAT6 phosphorylation (Y641) compared to AngII and IL-4 treated WT BMDMs. These alterations were at least partly mediated by macrophage as bone marrow transplantation from KO mice into WT mice aggravated cardiac remodeling. Mechanistically, AngII-infused KO mice showed hyperactivated IL-4/STAT6/PPARγ signaling and downregulated SOCS3 expression compared to AngII-infused WT mice. Our studies show that macrophage p47phox limits anti-inflammatory signaling and extracellular matrix remodeling in response to pressure-overload.Gene therapy (GT) has been reported to improve bone marrow function in individuals with Fanconi anemia (FA); however, its clinical application is still in the initial stages. We conducted this systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, to assess the long-term safety and clinical outcomes of GT in FA patients. Electronic searches from PubMed, Web of Science, Cochrane Library, and Google Scholar were conducted and full texts of articles meeting our inclusion criteria were reviewed. Three clinical trials were included, with a total of nine patients and mean age of 10.7 ± 5.7 years. All patients had lentiviral-mediated GT. A 1-year follow-up showed stabilization in blood lineages, without any serious adverse effects from GT. A metaregression analysis could not be conducted, as very little long-term follow-up data of patients was observed, and the median survival rate could not be calculated. Thus, we can conclude that GT seems to be a safe procedure in FA; however, further research needs to be conducted on the longitudinal clinical effects of GT in FA, for a better insight into its potential to become a standard form of treatment.

To investigate the impact of high-intensity local treatment (LT) on overall survival (OS) in patients with stage IV upper tract urothelial carcinoma (UTUC).

Within the National Cancer Database, we identified 7,357 patients diagnosed with stage IV UTUC from 2004 to 2015. Patients who underwent high-intensity LT, defined as radical surgery of the primary tumor, were compared with those who did not. Inverse probability of treatment weighting (IPTW) was used to balance baseline characteristics. Weighted survival analyses were used to test the association between high-intensity LT and OS. Multivariable Cox model was used to assess for independent predictors of OS. Sensitivity analysis was used to account for possible biases.

Among stage IV patients, 10.6% (n = 779) had locally advanced disease (T4), 32.6% (n = 2,399) had node-positive disease (N+) and 56.8% (N = 4,179) had distant metastases (M+). Fewer than half of the patients underwent high-intensity LT (n = 2,908, 39.5%) while the remainder did not. On IPTW-adjusted survival analysis, high-intensity LT was associated with a prolonged OS (11.
