We discuss the cellular control of protein palmitoylation and depalmitoylation, the relationship between lipid microdomains and lipidated and phospholipid binding proteins, and highlight the important unanswered questions in this emerging field.Despite fundamental differences in disease course and outcomes, neurodevelopmental (autism spectrum disorders - ASD) and neurodegenerative disorders (Alzheimer's disease - AD and Parkinson's disease - PD) present surprising, common traits in their molecular pathomechanisms. Uncontrolled oligomerization and aggregation of amyloid β (Aβ), microtubule-associated protein (MAP) tau, or α-synuclein (α-syn) contribute to synaptic impairment and the ensuing neuronal death in both AD and PD. Likewise, the pathogenesis of ASD may be attributed, at least in part, to synaptic dysfunction; attention has also been recently paid to irregularities in the metabolism and function of the Aβ precursor protein (APP), tau, or α-syn. Commonly affected elements include signaling pathways that regulate cellular metabolism and survival such as insulin/insulin-like growth factor (IGF) - PI3 kinase - Akt - mammalian target of rapamycin (mTOR), and a number of key synaptic proteins critically involved in neuronal communication. Understanding how these shared pathomechanism elements operate in different conditions may help identify common targets and therapeutic approaches.Despite the prevalence of neuroinflammation in psychiatric disorders, molecular mechanism underlying it remains elusive. Translocator protein 18 kDa (TSPO), also known as peripheral benzodiazepine receptor, is a mitochondrial protein implicated in the synthesis of steroids in a variety of tissues. Multiple reports have shown increased expression of TSPO in the activated microglia in the CNS. Radioactive probes targeting TSPO have been developed and used for imaging assessment in neurological and psychiatric disorders to examine neuroinflammation. Recent studies revealed that the wide range of stressors ranging from psychological to physical insults induced TSPO in human, suggesting that this protein could be an important tool to explore the contribution of microglia in stressor-related disorders. In this review, we first overview the microglial activation with TSPO in a wide range of stressors in human and animal models to discuss prevalent roles of TSPO in response of CNS to stressors. With recent update of the signaling pathway revealing link connecting TSPO with neuroinflammatory effectors such as reactive oxygen species, we discuss TSPO as a therapeutic targeting tool for suppression of adverse effect of stressors on long-lasting changes in animal behaviors and activities. Targeting TSPO which mediates neuroinflammation under the stress might pave the way to develop therapeutic intervention and prophylaxis of stressor-related disorder.Cerebral venous sinus thrombosis (CVST) is a rare type of stroke, which is life-threatening in severe cases. However, considerably less attention has been concentrated on the mechanism of neural cell damage after CVST. This study aims to investigate the role of endoplasmic reticulum stress, oxidative stress, and pyroptosis in a well-established rodent model of CVST. Rat brains were harvested at 0 h, 6 h, days 1, days 3, days 7, and days 14 post-CVST for measurement of corresponding indexes. Endoplasmic reticulum stress sensors (including protein kinase RNA-like ER kinase (PERK) and inositol-requiring enzyme-1α (IRE1α)), oxidative stress markers (thioredoxin-interacting protein (TXNIP) and peroxynitrite), NLRP3, caspase p20, IL-1β, and gasdermin D (GSDMD, an indicator of pyroptosis) were separately evaluated by Western-blot and Immunohistochemistry/Immunofluorescence. Co-immunoprecipitation and Fluorescent double-labeling were employed to probe into the relationship between TXNIP/peroxynitrite and NLRP3 inflammasome. In the damaged cortex region, profuse p-PERK, p-IRE1α, TXNIP were produced and predominantly localized in neurons accompanied by a small amount expressed in microglia and astrocytes. The levels of 3-nitrotyrosine (3-NT, as a footprint of peroxynitrite), NLRP3, caspase p20, IL-1β, and GSDMD were distinctly elevated post-CVST and cellular localization of peroxynitrite, NLRP3, caspase p20, and IL-1β was largely observed in neurons and/or microglia. Importantly, sites of enhanced TXNIP and 3-NT immunoreactivity were colocalized with increased NLRP3 staining, indicating the involvement of TXNIP and peroxynitrite in NLRP3 inflammasome activation and subsequent pyroptosis. Besides, co-immunoprecipitation also hinted that there might be an interaction or causality between TXNIP/peroxynitrite and NLRP3 inflammasome. We concluded that endoplasmic reticulum stress and oxidative stress may jointly lead to neuronal NLRP3 inflammasome activation and pyroptosis after CVST.
  Pancreatic surgery is associated with high morbidity, mainly due to infectious complications, so many centres use postoperative antibiotics (ATBpo) for all patients. However, antibiotic regimens vary according to local practices. The aims of this study were to describe the occurrence of surgical site infection (SSI) and ATBpo prescription after pancreatic surgery, and to determine the risk factors of postoperative SSI, in order to better define the clinical indications for ATBpo in this context.
 
  All patients undergoing scheduled major pancreatic surgery from January 2007 to November 2018 were included in this retrospective study.  https://www.selleckchem.com/products/Ilginatinib-hydrochloride.html  Patients were classified into four groups according to SSI and routine ATBpo prescription SSI+/ATBpo+, SSI-/ATBpo+, SSI+/ATBpo- and SSI-/ATBpo-. In addition, risk factors (fever and pre-operative biliary prosthesis) associated with the occurrence of SSI and ATBpo were analysed using a logistic regression model.
 
  Data from 149 patients (115 pancreaticoduodenectomies and 34 spleno presence of a biliary prosthesis does not.
 Non-routine ATBpo after major pancreatic surgery resulted in 85 (56%) patients being spared unnecessary antibiotic treatment. This suggests that routine ATBpo prescription could be excessive, but further studies are needed to confirm such antibiotic stewardship. Fever appears to be a relevant clinical sign for individual-based prescription, but the presence of a biliary prosthesis does not.
