Systematic review and meta-analysis of the efficacy and safety of minocycline in schizophrenia
2017
ObjectiveOur aim was to perform an updated systematic review and meta-analysis on the efficacy and safety of adjunctive minocycline as a treatment of schizophrenia.MethodsWe conducted a PubMed/Scopus database search from inception to 3 February 2016 for randomized, placebo-controlled trials (RCTs), open non-randomized studies, and case reports/series evaluating minocycline in patients with schizophrenia. Random-effects meta-analysis of positive, negative, depressive, and cognitive symptom rating scales, discontinuation and adverse effects rates calculating standardized mean difference (SMD), and risk ratios±95% confidence intervals (CI95%) were calculated.ResultsSix RCTs were eligible (mino…
High training volume is associated with increased prevalence of non-allergic asthma in competitive cross-country skiers.
2022
BackgroundCross-country skiers have a high prevalence of asthma, but its phenotypes and association with success in competitions are not known.ObjectiveTo investigate, by means of a postal survey, the relative proportions of allergic and non-allergic asthma in competitive cross-country skiers compared with the general population, to study how performance level and training volume are related to asthma and its type and to assess the possible risk factors for allergic and non-allergic asthma in competitive skiers.MethodsAll Finnish cross-country skiers enrolled in the largest national competitions in winter 2019 (n=1282), and a random sample (n=1754) of the general population of the same age …
Controlling the crystal growth of potassium iodide with a 1,1'-bis(pyridin-4-ylmethyl)-2,2'-biimidazole ligand (L) – formation of a linear [K4I4L4]n …
2018
The crystal growth of potassium iodide was controlled by using the neutral organic 1,1′-bis(pyridin-4-ylmethyl)-2,2′-biimidazole (L) ligand as a modifier. The selected modifier allows the preservation of original cubic [K4I4] units and their arrangement into a linear ligand-supported 1D chain. The supported [K4I4] cubes are only slightly distorted compared to the cubes found in pure KI salt. The N–K binding of the ligand to the KI salt, as well as weak I⋯H, N⋯H, and N⋯I interactions, stabilizes the structure to create a unique 1D polymer of neutral potassium iodide ionic salt inside the [K4I4L4]n complex.
Ehdotus ihmistä suhteellistavaksi sanastoksi
2021
”Ehdotus ihmistä suhteellistavaksi sanastoksi” käsittelee ja esittelee teoriasuuntausta, joka tunnetaan ”posthumanistisena”, keskittyen erityisesti sen käsitteisiin ja termeihin. Posthumanistinen ajattelu pyrkii käsitteelliseen uudistamiseen, jotta tunnistaisimme paremmin ne suhteellisuudet, joiden varassa ja lomassa ihmisten elämä ja merkitykset muotoutuvat – ja ne historiat, joissa ihminen on muotoutunut erilliseksi. Ehdotamme sanastoa, joka suhteellistaa juuri tätä käsitteellistä, kartesiolaisen humanismin ihmistä. Yhtäältä seuraamme käsitteellisen ajattelun muotoutumista erilaisten kontekstien paineissa, toisaalta pysähdymme tarkastelemaan tiettyjä, työskentelyssämme tärkeitä käsitteitä…
Nonlinear Absorption and Refraction of Picosecond and Femtosecond Pulses in HgTe Quantum Dot Films
2021
We report measurements of the saturated intensities, saturable absorption, and nonlinear refraction in 70-nm thick films containing 4 nm HgTe quantum dots. We demonstrate strong nonlinear refraction and saturable absorption in the thin films using tunable picosecond and femtosecond pulses. Studies were carried out using tunable laser pulses in the range of 400–1100 nm. A significant variation of the nonlinear refraction along this spectral range was demonstrated. The maximal values of the nonlinear absorption coefficients and nonlinear refractive indices determined within the studied wavelength range were −2.4 × 10−5 cm2 W−1 (in the case of 28 ps, 700 nm probe pulses) and −3 × 10−9 cm2 W−1 …
Psychrophiles: A source of cold-adapted enzymes for energy efficient biotechnological industrial processes
2021
Biocatalysts are the backbone of bioprocessing industries that are going through a phase of transition with reference to the requirement of extraordinary enzymes for various biochemical processes. This transition is well reported and documented by various researchers through elucidation of different features and applications of mesophilic and thermophilic enzymes. However, there is little information available about psychrophilic enzymes and their involvement in industrial processes. Therefore, understanding the features and functions of psychrophilic enzymes could suggest some of their novel applications in various industries such as food, agriculture, chemicals, pharmaceuticals, and waste…
Experimental Observation of a Large Low-Frequency Band Gap in a Polymer Waveguide
2018
The quest for large and low-frequency band gaps is one of the principal objectives pursued in a number of engineering applications, ranging from noise absorption to vibration control, and to seismic wave abatement. For this purpose, a plethora of complex architectures (including multiphase materials) and multiphysics approaches have been proposed in the past, often involving difficulties in their practical realization. To address the issue of proposing a material design that enables large band gaps using a simple configuration, in this study we propose an easy-to-manufacture design able to open large, low-frequency complete Lamb band gaps exploiting a suitable arrangement of masses and stif…
Community planning e community visioning. Visioni e scenari dal basso come “progetto tentativo” per riequilibrare spazio e società e ricostruire terr…
2017
Già dalla seconda metà degli anni 60 del secolo scorso in Italia, alcuni urbanisti (e non solo se si pensa alla poliedrica attività di Adriano Olivetti) incoraggiavano nuove metodologie di costruzione degli spazi urbani e territoriali mediante il recepimento della domanda sociale attraverso le pratiche di partecipazione degli abitanti alle scelte di governo del territorio. Tutto ciò avveniva sulla scia dell’advocacy planning molto in voga negli states, lanciato nel decennio precedente, ma anche dalla contaminazione del “situazionismo internazionale” principalmente di derivazione francese. Così dal nord al sud del nostro Paese, dalla scala urbana a quella territoriale, alcuni pionieri del ri…
Mappe dell'eccesso. Scenari: potenza e insidie (Maps of Excess, Scenarios, Potentialities and Pitfalls)
2012
Obiettivo dell’articolo è analizzare un "nuovo" strumento di pianificazione: lo scenario. Partendo dalle matrici teoriche e storiche alla base dello scenario stesso, e richiamando esempi pregressi di pianificazione, si prosegue nell’analisi al fine di far emergere i punti di forza e quelli critici dello strumento. Anche attraverso un’elencazione ragionata di entrambi, specificando cosa sia possibile pianificare, realizzare, tramite lo scenario, e quali - tra soggetti e Istituzioni - siano gli attori deputati, in che tempi e con quali esiti.
Environmental factors influencing the distribution and prevalence of Schistosoma haematobium in school attenders of ILembe and uThungulu Health Distr…
2017
Schistosoma haematobium infection is reported to facilitate the development of urogenital diseases. Its symptoms include haematuria, dysuria and tiredness, and it may cause cognitive decline in children. The prevalence of S. haematobium infection needs to be known in endemic areas and a mass treatment programme against the disease implemented. The aim of this study was to investigate the prevalence and intensity of S. haematobium infection in ILembe and uThungulu health districts, using the major symptom, haematuria, as an indicator. A total of 6 265 urine samples, from 96 rural schools, was collected for analysis using dipsticks. The prevalence of haematuria in the ILembe health district w…
