BACKGROUND Airway compromise caused by massive fluid extravasation in association with arthroscopic shoulder surgery is rare. However, it is even more rare to occur as a result of pleural effusion. We present this case to increase the awareness of this rare complication and show how to minimize the likelihood of this uncommon incident. [https://www.selleckchem.com/mTOR.html mTOR inhibitor review] CASE REPORT We describe a case of a 68-year-old woman who underwent elective shoulder arthroscopy for rotator cuff repair. She had immediate postoperative shortness of breath and was found to have bilateral pulmonary edema and pleural effusion accompanied by metabolic acidosis. She was managed conservatively in the intensive care unit and then transferred to the general ward after clinical and radiological improvement the next day. CONCLUSIONS This uncommon complication was self-limiting, and the patient recovered uneventfully. High clinical suspicion is required to address this event so proper rapid management can be made.BACKGROUND Bone fracture, a common injury to bones leads to various biophysiological changes and pathological responses in the body. The current study investigated curcumin for treatment of bone fracture in a rat model of bone trauma, and evaluated the related mechanism. MATERIAL AND METHODS The rats were separated randomly into 3 groups; sham, model, and curcumin treatment groups. The fracture rat model was established by transverse osteotomy in the right femur bone at the mid-shaft. The osteoblast count was determined using hematoxylin and eosin staining. Vascular endothelial growth factor (VEGF) and proliferating cell nuclear antigen (PCNA) expression were measured by western blotting. RESULTS The rpS6-phosphorylation was suppressed and light chain 3 (LC3II) expression elevated in the curcumin treated group of the fracture rat model. In the curcumin-treated group, mineralization of fracture calluses was markedly higher on day 14 of fracture. The formation of osteoblasts was observed at a greater rate in the curcumin treated group compared to the model rat group. Treatment of rats with curcumin significantly (P less then 0.05) promoted expression of PCNA and VEGF. The decrease in CD11b+/Gr-1+ cell expansion in rats with bone trauma was alleviated significantly by curcumin treatment. A marked increase in arginase-1 expression in rats with bone trauma was caused by curcumin treatment. CONCLUSIONS In summary, curcumin activates autophagy and inhibits mTOR activation in bone tissues of rats with trauma. The curcumin promoted myeloid-derived suppressor cell (MDSC) proliferation and increased expansion of MDSCs in a rat model of trauma. Therefore, curcumin may have beneficial effect in patients with bone trauma and should be evaluated further for development of treatment.Post-translational modification (PTM) in histone proteins is a covalent modification which mainly consists of methylation, phosphorylation, acetylation, ubiquitylation, SUMOylation, glycosylation, and ADP-ribosylation. PTMs have fundamental roles in chromatin structure and function. Histone modifications have also been known as epigenetic markers. The PTMs that have taken place in histone proteins can affect gene expression by altering chromatin structure. Histone modifications act in varied biological processes such as transcriptional activation/inactivation, chromosome packaging, mitosis, meiosis, apoptosis, and DNA damage/repair. Defects in the PTMs pathway have been associated with the occurrence and progression of various human diseases, such as cancer, heart failure, autoimmune diseases, and neurodegenerative disorders such as Parkinson's disease, Alzheimer's disease, and Huntington's disease. Histone modifications are reversible and used as potential targets for cancer therapy and prevention. Recent different histone PTMs have key roles in cancer cells since it has been shown that histone PTMs markers in cancers are acetylation, methylation, phosphorylation, and ubiquitylation. In this review, we have summarized the six most studied histone modifications and have examined the role of these modifications in the development of cancer.Correction to J Biosci (2019) 44119 https//doi.org/10.1007/s12038-019-9933-z In the October 2019 Special Issue of the Journal of Biosciences on Current Trends in Microbiome Research, in the Review article titled "Visual exploration of microbiome data" by Bhusan K.

To study the roles of SOD3 in inflammatory regulation of MP infection, human A549 type II alveolar epithelial cells were stimulated with 107 CCU/ml of MP to build MP infection in vitro. Secretion of pro-inflammatory cytokine interleukin (IL)-8 and tumor necrosis factor (TNF)-α were measured via enzyme-linked immunosorbent assay (ELISA) to assess the inflammatory response of A549 cells. Levofloxacin (LVFX) was used as an anti-inflammatory drug while recombinant TNF-α was used as an inflammatory promotor in MP-infected cells. Transcriptional activity of nuclear factor (NF)-κB was assessed by detecting protein levels of nuclear NF-κB and cytoplasm NF-κB using Western blot analysis. Our data suggested that the expression of SOD3 mRNA and protein, as well as content of SOD3 in cultured supernatant, were time-dependently inhibited in MP-infected A549 cells. However, lentiviruses-mediated SOD3 overexpression alleviated inflammatory response of MP-infected A549 cells, and prevented the unclear translocation of NF-κB, as evidenced by obviously reducing the production of IL-8 and TNF-α in cell cultured supernatant, as well as decreasing nuclear NF-κB while increasing cytoplasm NF-κB. Inspiringly, SOD3 overexpression induced anti-inflammatory effect and the inactivation of NF-κB was similar to that of 2 lg/ml of LVFX, but reversed by additional TNF-α treatment. Therefore, we can conclude that transcriptional activity of NF-jB was the underlying mechanism, by which SOD3 regulated inflammatory response in MP infection in vitro.
