The aim of this systematic review and meta-analysis was to determine the effect of physical exercise on fall prevention and the characteristics required for effective exercise.

Systematic review and meta-analysis of randomised controlled trials.

Six databases (PubMed, Cochrane Library, Web of Science, Excerpta Medica Database, SinoMed and China National Knowledge Infrastructure) were searched to find the relevant randomised controlled trials published before January 2021. The study was reported in compliance with PRISMA statement. The included studies were assessed for quality using the Cochrane "Risk of Bias" assessment tool, and the data were analysed with review manager.

Overall, fourteen studies were included. Compared physical exercise with normal daily life, the pooled effect size of all trials indicated that intervention had significant effect on fall prevention (RR=0.85, 95% CI=0.73-0.98). The result of subgroup revealed that long-term exercise and balance exercise could reduce falling, while short-term exercise and more complex exercise couldn't.

Exercise may be effective in reducing falls, and long-term balance exercise played a role in preventing falls in nursing homes.

Dermatobia hominis (D.hominis) is a botfly that causes furuncular myiasis in several species of domestic and wild animals. However, reports of feline infestation by larvae of this dipteran are rare.

To report the natural occurrence of furuncular myiasis caused by D.hominis in five cats and the efficacy of topical fluralaner for its treatment.

Five adult mixed-breed cats (four males, one female) were diagnosed and treated, all living in the state of Rio de Janeiro, Brazil.

The cats were treated with topical fluralaner. After this treatment, the larvae were dead after 24h in three cats and after 48h in two. There was spontaneous expulsion of larvae in two cats, and it was necessary to perform manual expression for removal of dead larvae in the other three cats.

Dermatobia hominis can cause furuncular myiasis in cats, although this appears to be less common than in other animal species. Topical fluralaner proved to be effective in the treatment of this parasitic disease.

However, dendrite growth severely destabilizes the electrode/electrolyte interface, and accelerates the generation of side reactions, which eventually degrade the electrochemical performance. Here, an artificial interface film of nitrogen (N)-doped graphene oxide (NGO) is one-step synthesized by a Langmuir-Blodgett method to achieve a parallel and ultrathin interface modification layer (≈120 nm) on Zn foil. The directional deposition of Zn crystal in the (002) planes is revealed because of the parallel graphene layer and beneficial zincophilic-traits of the N-doped groups. Meanwhile, through the in situ differential electrochemical mass spectrometry and in situ Raman tests, the directional plating morphology of metallic Zn at the interface effectively suppresses the hydrogen evolution reactions and passivation. Consequently, the pouch cells pairing this new anode with LiMn2 O4 cathode maintain exceptional energy density (164 Wh kg-1 after 178 cycles) at a reasonable depth of discharge, 36%. This work provides an accessible synthesis method and in-depth mechanistic analysis to accelerate the application of high-specific-energy AZIBs.Volatile organic compounds (VOCs) as a non-negligible aircraft cabin air quality (CAQ) factor influence the health and comfort of passengers and crew members. On-board measurements of carbonyls (short-chain (C1 -C6 )) and other volatile organic compounds (VOCs, long-chain (C6 -C16 )) with a total of 350 samples were conducted in 56 commercial airliner cabins covering 8 aircraft models in this study. The mean concentration for each individual carbonyl compound was between 0.3 and 8.3 μg/m3 (except for acrolein & acetone, average = 20.7 μg/m3 ) similar to the mean concentrations of other highly detected VOCs (long-chain (C6 -C16 ), 97% of which ranged in 0-10 μg/m3 ) in aircraft cabins. Formaldehyde concentrations in flights were significantly lower than in residential buildings, where construction materials are known formaldehyde sources. Acetone is a VOC emitted by humans, and its concentration in flights was similar to that in other high-occupant density transportation vehicles. Bicuculline supplier The variation of VOC concentr VOC database of cabin environment, especially for carbonyls. The literature review of carbonyls in the past 20 years contributes to the understanding the current status of cabin air quality (CAQ). The analysis of VOC concentration variation for different flight phases, flight duration, and aircraft age lays a foundation for exploring effective control methods, including ventilation and purification for cabin VOC pollution. The enriched VOC data is helpful to explore the key VOCs of aircraft cabin environment and to evaluate the acute/chronic health exposure risk of pollutants for passengers and crew members.Supplement-free induction of cellular differentiation and polarization solely through the topography of materials is an auspicious strategy but has so far significantly lagged behind the efficiency and intensity of media-supplementation-based protocols. Consistent with the idea that 3D structural motifs in the extracellular matrix possess immunomodulatory capacity as part of the natural healing process, it is found in this study that human-monocyte-derived macrophages show a strong M2a-like prohealing polarization when cultured on type I rat-tail collagen fibers but not on collagen I films. Therefore, it is hypothesized that highly aligned nanofibrils also of synthetic polymers, if packed into larger bundles in 3D topographical biomimetic similarity to native collagen I, would induce a localized macrophage polarization. For the automated fabrication of such bundles in a 3D printing manner, the strategy of "melt electrofibrillation" is pioneered by the integration of flow-directed polymer phase separation into melt electrowriting and subsequent selective dissolution of the matrix polymer postprocessing.
