Delayed Presentation of Congenital Diaphragmatic Hernia in the Emergency Department: Case Report
No full textIntroduction: Congenital diaphragmatic hernia (CDH) is an embryological defect of the diaphragm that typically presents in the neonatal period with respiratory distress. However, delayed presentations do occur rarely and can pose diagnostic and therapeutic challenges.
Case Report: We describe the case of a 9-month-old male who presented to the emergency department with respiratory distress and was subsequently diagnosed with congenital diaphragmatic hernia.
Conclusion: This case underscores the importance of considering CDH in the differential diagnosis of pediatric patients presenting to the Emergency Department (ED) with unexplained respiratory or gastrointestinal symptoms, even beyond the neonatal period

No full textThe fall of Egyptian president Morsi from the perspective of coop-proofing
No full textThe Arab Spring caused a political turmoil in the Middle East. An established order has undergone significant changes in many countries including Egypt. The Muslim Brotherhood emerged as the most powerful actor in Egyptian politics after the fall of a regime of Husni Mubarak. This was manifested by victories in both parliamentary and presidential elections. However, a year later after his triumph, Islamist president Mohammad Morsi was toppled by the military. By using the concept of coup-proofing, this diploma thesis examines, whether Morsi attempted to prevent such event from the occurence. The author forms a particular concept of coup-proofing from its general counterpart in order to reflect the specifics of Egypt. With its help, he analyzes relevant events of Morsi's presidency and identifies the application of coup-proofing measures. In its last part, the thesis answers which coup-profing methods were used by Morsi's regime and gives an interpretation of those political moves. This thourough examination of a development prior to the ouster of Muslim Brotherhood from power contributes to a contemporary civil-military relations debate, which was recently given an impulse by the Arab Spring
Clinical research using extracellular vesicles: insights from the International Society for Extracellular Vesicles 2018 Annual Meeting
No full textThe abstracts presented at the 2018 International Society for Extracellular Vesicles Annual Meeting offer unique insight into the newest discoveries related to the biology and applied use of extracellular vesicles (EVs). As an extension of a recent “Clinical-Wrap Up” discussion at the International Society for Extracellular Vesicles 2018 Annual Meeting, a systematic review of each abstract was performed to determine which abstracts could be considered clinical research. Once the clinical research abstracts were identified, systematic data extraction included: the major focus of each clinical research abstract; the countries in which the work was done; and the sample size, if provided in the abstract. Each abstract was reviewed by two independent authors, with a third author resolving discrepancies in cases of disagreement. 174 out of 656 (27%) unique abstracts were determined to be clinical research. Oncology was a principal research focus (51 of the 174 clinical research abstracts, 29%). Many other clinical research abstracts presented at the International Society for Extracellular Vesicles 2018 Annual Meeting focused on the use of human samples for development of methods for potential application in the clinic. Beyond oncology and methods development, a wide range of topics was represented, including cardiovascular disease, neurodegenerative disease, genetics, and many others. Current research involving EVs highlights the common, but false dichotomy of science into curiosity-driven basic science or application-driven clinical research, when in fact both quest for understanding and intent to apply the findings appeared to drive much of the work at the International Society for Extracellular Vesicles 2018 Annual Meeting. Using Pasteur’s Quadrant as a framework, we discuss where the field of EV research is heading and how we may gain insight into the biological function of EVs in tandem with how they may benefit individual health
Photochemical oxidation of short-chain polychlorinated n-alkane mixtures using H2O2/UV and the photo-Fenton reaction.
No full textThe photochem. oxidn. of short-chain polychlorinated n-alkane (PCA) mixts. were studied using H2O2/UV and modified photo-Fenton conditions (Fe3+/H2O2/UV) in both Milli-Q and lake water. All PCA mixts., including chlorinated (Cl5 to Cl8) decanes, undecanes, dodecanes and tridecanes degraded in 0.02M H2O2/UV at pH 2.8 in pure water, with 80 ± 4% disappearance after 3 h of irradn. using a 300. nm light source. Degrdn. was somewhat enhanced under similar conditions but in natural water. The modified photo-Fenton system was more effective in degrading PCAs, with 72% and 80% disappearance of chlorinated decanes in 4 S min of irradn. in pure and natural water, resp. Carbon chain-length had minimal effect on degrdn. rates; however, increased degree of chlorination (from Cl5 to Cl8) resulted in slower initial degrdn. rates and less complete conversion after 3 h of irradn. Three hours of irradn. in natural water/H2O2/UV resulted in 95% degrdn. of parent PCAs accompanied by 93% release of chloride ion. Quant. dechlorination, which may be indicative of complete mineralization, suggests that this is an effective water remediation technique for PCAs
Photocatalytic degradation of 1,10-Dichlorodecane in Aqueous suspensions of TiO2: a reaction of Adsorbed chlorinated alkane with Surface hydroxyl radicals.
No full text1,10-Dichlorodecane (D2C10) is shown to be effectively photodegraded in aqueous suspensions of TiO2 using a photoreactor equipped with 300 nm lamps. Solutions exposed to UV light intensities of 3.6 × 10-5 Ein L-1 min-1, established by ferrioxalate actinometry, showed negligible direct photolysis in the absence of TiO2. The degradation rate was optimal with 150 mg/L of TiO2 and a D2C10 concentration (240 μg/L) approaching its solubility limit. Kinetics of photodegradation followed a Langmuir−Hinshelwood model suggesting that the reaction occurred on the surface of the photocatalyst. The presence of h+vb and OH• radical scavengers, including methanol and iodide, inhibited the degradation supporting a photooxidation reaction. Electron scavengers (Ag+, Cu2+, and Fe3+) had small effects on the degradation rate. The lack of transformation of D2C10 in acetonitrile as solvent indicated that the major oxidants were OH• radicals. The presence of tetranitromethane, effectively eliminating the formation of free OH• radicals, did not affect the degradation rates significantly. This result, combined with observed increases in photolysis rates with the degree of adsorption of D2C10 onto the surface of the photocatalyst, confirmed that the reaction involved adsorbed 1,10-dichlorodecane and surface bound OH• radicals
Homogeneous degradation of 1,2,9,10-tetrachlorodecane in aqueous solutions using hydrogen peroxide, iron and UV light
No full textThe homogeneous degradation of the polychlorinated n-alkane, 1,2,9,10-tetrachlorodecane (T4C10), was studied in aqueous solutions of hydrogen peroxide, including Fenton and photo-Fenton reaction conditions. All solutions were adjusted to a pH of 2.8 and an ionic strength of 0.1 M NaClO4 prior to photolysis. T4C10 (2 x 10(-6) M) was substantially degraded by the H2O2/UV system (1.0 x 10(-2) M H2O2), with 60% disappearance in 20 min of irradiation in a photoreactor equipped with 300 nm lamps of light intensity 3.6 x 10(-5) Ein L(-1) min(-1) (established by ferrioxalate actinometry). The reaction produced stoichiometric amounts of chloride ion indicating complete dechlorination of the chlorinated n-alkane. T4C10 degraded very slowly under Fenton (Fe2+/H2O2/dark) and Fenton-like (Fe3+/H2O2/dark) conditions. However, when the same solutions were irradiated, T4C10 degraded more rapidly than in the H2O2/UV system, with 61% disappearance in 10 min of exposure. The rapid degradation is related to the enhanced degradation of hydrogen peroxide to oxidizing *OH radicals under photo-Fenton conditions. Degradation was inhibited in both the H2O2/UV and photo-Fenton systems by the addition of KI and tert-butyl alcohol due to *OH scavenging
Morsi: rave e taranta, un’estetica della corporeità ebbra
No full textThe end of the Eighties and till to the beginning of the Nineties were the years of the beginning of Rave culture in Europe and in Italy. The study will analyze the analogies between the origin of the Taranta night and the rave wave who lasted for a few years. Through the categories of tribù (Maffesoli), music, night and TAZ (Bey), the author will accompany the reader into a journey where space and time are not the traditional ones anymore: they are subverted thanks to the repetitivity of a music like Taranta and Techno. Dystopian places and sciamanic attitude to rituals within the praxis of the dance, make Taranta Night and Rave culture in a constant dynamic between past and futur
