Ion mobility action spectroscopy of flavin dianions reveals deprotomer-dependent photochemistry

The intrinsic optical properties and photochemistry of flavin adenine dinucleotide (FAD) dianions are investigated using a combination of tandem ion mobility spectrometry and action spectroscopy. Two principal isomers are observed, the more stable form being deprotonated on the isoalloxazine group and a phosphate (N-3,PO4 deprotomer), and the other on the two phosphates (PO4,PO4 deprotomer). Ion mobility data and electronic action spectra suggest that photo-induced proton transfer occurs from the isoalloxazine group to a phosphate group, converting the PO4,PO4 deprotomer to the N-3,PO4 deprotomer. Comparisons of the isomer selective action spectra of FAD dianions and flavin monoanions with solution spectra and gas-phase photodissociation action spectra suggests that solvation shifts the electronic absorption of the deprotonated isoalloxazine group to higher energy. This is interpreted as evidence for significant charge transfer in the lowest optical transition of deprotonated isoalloxazine. Overall, this work demonstrates that the site of deprotonation of flavin anions strongly affects their electronic absorptions and photochemistry

Comparison of Intravenous Ranitidine with Pantoprazole in Decreasing Gastric Fluid Acidity in Emergency Cesarean Section

Objectives: Peri-operative aspiration of gastric contents is a problem that causes certain respiratory problems including ARDS. Prophylaxis against aspiration of gastric contents is performed routinely in elective surgeries, but there is rare evidence on the efficacy of this method in emergency cesarean section. Materials and Methods: This is a randomized, controlled, double-blinded clinical trial. 60 parturients undergoing emergency cesarean section were randomly assigned into three groups of 20 each. They were allocated into two study and one placebo groups. The study group one and two received intravenous ranitidine (IV) 50 mg or IV pantoprazole 40 mg, half an hour before induction of GA, respectively. The placebo group was administered just 5 ml of isotonic saline half an hour before GA induction. After intubation and confirmation of endotracheal tube insertion, the gastric contents were aspirated through a nasogastric tube for evaluation of acidity and volume. Results: A statistical difference between group one and two with the control group was observed in the acidity of gastric contents, but there was no difference in volume. Also, the PH level of gastric contents in patients receiving pantoprazole was significantly higher than the isotonic saline (

An overview of filtration efficiency through the masks: Mechanisms of the aerosols penetration

The masks have always been mentioned as an effective tool against environmental threats. They are considered as protective equipment to preserve the respiratory system against the non-desirable air droplets and aerosols such as the viral or pollution particles. The aerosols can be pollution existence in the air, or the infectious airborne viruses initiated from the sneezing, coughing of the infected people. The filtration efficiency of the different masks against these aerosols are not the same, as the particles have different sizes, shapes, and properties. Therefore, the challenge is to fabricate the filtration masks with higher efficiency to decrease the penetration percentage at the nastiest conditions. To achieve this concept, knowledge about the mechanisms of the penetration of the aerosols through the masks at different effective environmental conditions is necessary. In this paper, the literature about the different kinds of face masks and respiratory masks, common cases of their application, and the advantages and disadvantages of them in this regard have been reviewed. Moreover, the related mechanisms of the penetration of the aerosols through the masks are discussed. The environmental conditions affecting the penetration as well as the quality of the fabrication are studied. Finally, special attention was given to the numerical simulation related to the different existing mechanisms

Involvement of PPARγ in the protective action of tropisetron in an experimental model of ulcerative colitis

Inflammatory bowel disease (IBD) is a chronic inflammation of the gastrointestinal (GI) tract. Tropisetron, a selective 5-HT3 receptor antagonist, is highly used to counteract chemotherapy-induced emesis. Previous studies revealed the anti-in�ammatory properties of this drug. The aim of this study was to evaluate the role of peroxisome proliferator-activated receptor gamma (PPARγ) receptor in the protective effect of tropisetron in an animal model of ulcerative colitis. Experimental colitis was induced by a single intra-colonic instillation of 4 (V/V) acetic acid in male rats. Tropisetron (3 mg/kg) and GW9662 (PPARγ antagonist) (5 mg/kg) were given twice daily for 2 days after colitis induction. Forty-eight hours after induction of colitis, colon was removed and macroscopic and microscopic features were given. Moreover, colonic concentrations of malondialdehyde (MDA), nitric oxide (NO), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) levels, myeloperoxidase (MPO), and PPARγ activity were assessed. Both macroscopic and histopathological features of colonic injury were markedly ameliorated by tropisetron. Likewise, levels of NO, MDA, TNF-α, and IL-1β diminished significantly (p <.05). GW9662 reversed the effect of tropisetron on these markers partially or completely. In addition, tropisetron increased the PPARγ and decreased the MPO activity (p <.05). Tropisetron exerts notable anti-in�ammatory effects in acetic acid-induced colitis in rats, which is probably mediated through PPARγ receptors. © 2016 Informa UK Limited, trading as Taylor & Francis Group

Educational Needs of Nurses in Intensive Care Unit for Poisoned Patients

Objectives: Poisoned patients are at risk of impaired ventilation in many situations. The purpose of this descriptive study was to investigate the impact of educational workshops on nurses' knowledge, confidence, and attitude in taking care of poisoned patients. Materials and Methods: This descriptive study was performed on 60 nursing staff in the intensive care unit (ICU) for poisoned patients in Imam Reza (p) hospital, Mashhad, Iran. Data was gathered by a researcher-designed questionnaire. Studied scales included perceived importance and novelty of educational meeting, matching with professional and educational needs, illustration of practical and knowledge weaknesses and strength and finally satisfaction in holding regular workshops annually. Two, half day workshops were held and various items were taught with various methods. The knowledge of participants was assessed by pretests and post-tests consisting of 12 items related to workshop topics. The impact of these educational meetings was evaluated and the results were analyzed by the SPSS software. Results: According to the results, workshops improved awareness of nurses about their weakness and strength points, professional knowledge and their interest and attention; likewise all participants had the same opinion about a strong need to hold similar workshops more than once and preferably 2 to 3 times annually. Conclusion: It seems that short educational courses in small groups for reviewing the old data and recent findings in the context of critical care are useful in order to promote the knowledge and skills of ICU staff in taking care of poisoned patient

Treg-Cell Control of a CXCL5-IL-17 Inflammatory Axis Promotes Hair-Follicle-Stem-Cell Differentiation During Skin-Barrier Repair.

Restoration of barrier-tissue integrity after injury is dependent on the function of immune cells and stem cells (SCs) residing in the tissue. In response to skin injury, hair-follicle stem cells (HFSCs), normally poised for hair generation, are recruited to the site of injury and differentiate into cells that repair damaged epithelium. We used a SC fate-mapping approach to examine the contribution of regulatory T (Treg) cells to epidermal-barrier repair after injury. Depletion of Treg cells impaired skin-barrier regeneration and was associated with a Th17 inflammatory response and failed HFSC differentiation. In this setting, damaged epithelial cells preferentially expressed the neutrophil chemoattractant CXCL5, and blockade of CXCL5 or neutrophil depletion restored barrier function and SC differentiation after epidermal injury. Thus, Treg-cell regulation of localized inflammation enables HFSC differentiation and, thereby, skin-barrier regeneration, with implications for the maintenance and repair of other barrier tissues
