Notes

Minimal recognition and under-diagnosis associated with an under active thyroid.
Compared with H9N2 IAV, H1N1 IAV induced higher mortality rates and more obvious body weight loss in the mice. In addition, IAV or H1N1 IAV induced a significantly higher level of CXCL10 mRNA in the human respiratory epithelial cells or the mouse lungs, respectively. In mice, the high level of Cxcl10 mRNA was accompanied by the abundant infiltrated neutrophils and more severe pathological changes in the lungs. Together, the data presented here indicate that the pathogenicity of influenza viruses is correlated with the IFN-α subtypes induced by influenza viruses. KEY POINTS • Different influenza viruses induce differential inflammation responses. • Various influenza viruses induce diverse expression profiles of IFN-α subtypes. • The locally produced IFN-α subtypes correlated to the differential inflammation. Graphical abstract.Symbiotic partnerships are widespread in nature and in industrial applications yet there are limited examples of laboratory communities. Therefore, using common photobionts and mycobionts similar to those in natural lichens, we create an artificial lichen-like symbiosis. While Aspergillus nidulans and Aspergillus niger could not obtain nutrients from the green algae, Chlorella, and Scenedesmus, the cyanobacteria Nostoc sp. PCC 6720 was able to support fungal growth and also elevated the accumulation of total biomass. The Nostoc-Aspergillus co-cultures grew on light and CO2 in an inorganic BG11 liquid medium without any external organic carbon and fungal mycelia were observed to peripherally contact with the Nostoc cells in liquid and on solid media at lower cell densities. Overall biomass levels were reduced after implementing physical barriers to indicate that physical contact between cyanobacteria and heterotrophic microbes may promote symbiotic growth. The synthetic Nostoc-Aspergillus nidulans co-cultures also exhibited robust growth and stability when cultivated in wastewater over days to weeks in a semi-continuous manner when compared with axenic cultivation of either species. These Nostoc-Aspergillus consortia reveal species-dependent and mutually beneficial design principles that can yield stable lichen-like co-cultures and provide insights into microbial communities that can facilitate sustainability studies and broader applications in the future. KEY POINTS • Artificial lichen-like symbiosis was built with wild-type cyanobacteria and fungi. • Physical barriers decreased biomass production from artificial lichen co-cultures. • Artificial lichen adapted to grow and survive in wastewater for 5 weeks.Atherosclerosis is a chronic inflammatory disease mediated by monocyte infiltration and cholesterol deposition into the subendothelial area, resulting in foam cell development. Probiotics are live bacteria that are beneficial for health when administered orally in adequate amounts. In this study, 8-week-old atherosclerosis-prone apolipoprotein E-deficient (ApoE-/-) mice were fed with or without Lactobacillus plantarum ATCC 14917 per day for 12 weeks. Serum was collected to analyse the lipid profile, oxidative status and proinflammatory cytokines. The heart was isolated to quantify the atherosclerotic lesion size in the aortic arch. Quantitative real-time polymerase chain reaction was performed to determine the expression levels of tumour necrosis factor-alpha (TNF-α) and interleukin (IL)-1β in the aorta. The proteins extracted from the aorta were used for Western blot analysis to assess the expression levels of nuclear factor kappa B (NF-κB) and inhibitor of NF-κB (IκBα). The composition of gut microbiota was also examined through high-throughput sequencing. Results showed that the daily consumption of L. plantarum ATCC 14917 had no effect on body weight and lipid profile. L. plantarum ATCC 14917 treatment significantly inhibited atherosclerotic lesion formation. In addition, the oxLDL, MDA, TNF-α and IL-1β levels were significantly reduced, whereas the SOD level was induced in the bacteria + high-fat diet group. Furthermore, the administration of L. plantarum ATCC 14917 significantly attenuated IκBα protein degradation and inhibited the translocation of P65 subunits of NF-κB. L. plantarum ATCC 14917 treatment also modulated the composition of gut microbiota in ApoE-/- mice. Our findings showed that L. plantarum ATCC 14917 supplementation decreases the progression of atherosclerotic lesion formation by alleviating the inflammatory process and lowering oxidative stress.Purpose Obesity, neoadjuvant-radiotherapy, tumour proximity to the anal verge and previous abdominal surgery are factors that might increase the intra-operative difficulty of laparoscopic rectal cancer surgery. However, whether patients with these 'high-risk' characteristics are subject to worse short- or long-term outcomes is debated. The aim of this study is to examine the short- and long-term clinical and oncological outcomes of patients receiving laparoscopic rectal surgery with any of these high-risk characteristics and compare them with patients that do not possess any of these high-risk features. Methods For the purpose of this study data from consecutive patients receiving laparoscopic rectal cancer resections between 2006 and 2016 from two centres were analysed. High-risk patients were defined as patients with either one of the following characteristics BMI ≥ 30, neoadjuvant chemoradiotherapy, tumour less then 8 cm from the anal verge and previous abdominal surgery. Results A total of 313 patients were identified (227 high risk, 86 low risk). Short-term outcomes were similar between the two groups with the exception of blood loss and length of stay, which were higher in the high-risk group (10 vs 2.5 ml, p = 0.045; 7 vs 5 days, p = 0.001). There were no statistically significant differences in 5-year overall survival (79.7% vs 79.8%, p = 0.757), disease-free survival (76.8% vs 69.3%, p = 0.175), distant disease-free interval (84.8% vs 79.7%, p = 0.231) and local recurrence-free interval (100%, 97.4%, p = 0.162) between the two groups. Conclusion Similar short- and long-term outcomes can be achieved in high-risk and low-risk patients receiving laparoscopic rectal surgery. selleck chemical The presented data support the suitability of laparoscopic surgery for this group of patients.
