Intracellular pathogens affect diverse host cellular defence and metabolic pathways. Here, we used infection with Francisella tularensis to identify SON DNA-binding protein as a central determinant of macrophage activities. RNAi knockdown of SON increases survival of human macrophages following F. tularensis infection or inflammasome stimulation. SON is required for macrophage autophagy, interferon response factor 3 expression, type I interferon response and inflammasome-associated readouts. SON knockdown has gene- and stimulus-specific effects on inflammatory gene expression. SON is required for accurate splicing and expression of GBF1, a key mediator of cis-Golgi structure and function. Chemical GBF1 inhibition has similar effects to SON knockdown, suggesting that SON controls macrophage functions at least in part by controlling Golgi-associated processes.Brain injuries due to abusive head trauma (AHT) in infants are not rare and they are probably under-diagnosed. Retinal hemorrhages (RH) constitute a cardinal symptom of AHT and AHT is the most common cause of RH in infants next to childbirth. Retinoschisis with or without retinal folds is highly suggestive of AHT and never seen secondary to childbirth. Bilateral extensive RH that are too numerous to count, multilayered and extending to the peripheral retina in infants less then 3 years of age, in combination with brain injury and in absence of leukemia, ruptured brain aneurysm/AVM, fatal head crush or known severe accidental trauma must be considered to be caused by AHT in the absence of any other compelling factors. selleck chemicals The ophthalmologist has an important role and a responsibility in describing the pattern of RH and in evaluating the likelihood of the diagnosis in the medical report and in communication with pediatricians and child protection team.We here describe the current knowledge about the radiologic and histologic pulmonary features of covid-19, caused by SARS-CoV-2, and present lung histology from a case with fatal disease. Initial findings on computed tomography (CT) typically include peripheral multifocal bilateral ground-glass opacities, and correspondingly microscopic alveolar edema. This is followed by peripheral consolidations with air bronchogram and perilobular pattern on CT, signs of organizing pneumonia, corresponding to loose (potentially reversible) fibrosis. The posterior parts of the lungs and the lower lobes are typically more markedly affected. In severe disease with acute respiratory distress syndrome, thickened interlobular septa and crazy paving pattern appear on CT, which corresponds to histologic diffuse alveolar damage with, depending on the stage of the disease, features such as edema, hyaline membranes, reactive epithelium, inflammation, and fibrosis.Background Hyperhomocysteinemia (HHcy) plays a synergistic role with hypertension in vascular injury; however, the relationship between HHcy and hypertension in renal injury remains unclear. Here, we sought to evaluate the relationship between HHcy and hypertension in the context of renal injury and to elucidate the mechanism of action underlying this relationship. Methods Wistar Kyoto (WKY) and spontaneously hypertensive (SHR) rats were randomized into WKY, WKY+HHcy, SHR, and SHR+HHcy groups. Blood pressure, plasma homocysteine, serum malondialdehyde (MDA), serum superoxide dismutase (SOD), urinary albumin creatinine ratio (UACR) and glomerular filtration rate (GFR) were measured. Renal histopathology and expression levels of NOX2, NOX4, and nephrin in the kidneys were examined. Results The WKY+HHcy and SHR groups exhibited lower serum SOD and GFR levels, relative to the WKY group, along with higher levels of both serum MDA and UACR. Higher mRNA and protein expression levels of NOX2 and NOX4, along with lower expression levels of nephrin, were observed in the kidneys of WKY+HHcy and SHR rats, relative to WKY controls, respectively. Similar effects were observed in the SHR+HHcy group, relative to the SHR group and WKY+HHcy group, respectively. PAS staining showed an increase in the glomerular extracellular matrix in the WKY+HHcy and SHR+HHcy groups compared to their respective controls. Conclusions HHcy appears to synergistically increase hypertensive renal damage by enhancing oxidative stress.Oncomelania hupensis is the unique intermediate host of Schistosoma japonicum. As an irreplaceable prerequisite in the transmission and prevalence of schistosomiasis japonica, an in-depth study of this obligate host-parasite interaction can provide glimpse into the molecular events in the competition between schistosome infectivity and snail immune resistance. In previous studies, we identified a macrophage migration inhibitory factor (MIF) from O. hupensis (OhMIF), and showed that it was involved in the snail host immune response to the parasite S. japonicum. Here, we determined the crystal structure of OhMIF and revealed that there were distinct structural differences between the mammalian and O. hupensis MIFs. Noticeably, there was a projecting and structured C-terminus in OhMIF, which not only regulated the MIF's thermostability but was also critical in the activation of its tautomerase activity. Comparative studies between OhMIF and human MIF (hMIF) by analyzing the tautomerase activity, oxidoreductase activity, thermostability, interaction with the receptor CD74 and activation of the ERK signaling pathway demonstrated the functional differences between hMIF and OhMIF. Our data shed a species-specific light on structural, functional, and immunological characteristics of OhMIF and enrich the knowledge on the MIF family.Long-term cancer survivorship is an emerging field that focuses on physical late-effects and psychosocial implications for the inflicted. This study wishes to cast light on the underlying ontological aspect of long-term survivorship by philosophically exploring how being in life post cancer is perceived by survivors. Sixteen in-depth interviews with 14 Danish cancer survivors were conducted by the author. Having faced a life-threatening disease but no longer being in imminent danger of dying, survivors still considered death a defining yet dynamic component in their approach to life as a moving toward the end, sparking a sense of vitality in mortality. In order to unfold the interviewees' renewed existential understanding post cancer, this study employs Martin Heidegger's ontological analysis of death. In survivorship, my participants can thus be understood as being left with the perpetual choice between living in inauthenticity or in authenticity. The difference between the two modes of existence exhibits two diverging ways of relating to death, self, and being-in-the-world.
