For example, surveys of laboratory and wild populations of zebra finches (Taeniopygia guttata) document consistent patterning of vocal elements ("syllables") with respect to their acoustic properties (e.g., duration, mean frequency). Furthermore, such universal patterns are also produced by birds that are experimentally tutored with songs containing randomly sequenced syllables ("tutored birds"). Despite extensive demonstrations of learning biases, much remains to be uncovered about the nature of biological predispositions that bias song learning and production in songbirds. Here we examined the degree to which "innate" auditory templates and/or biases in vocal motor production contribute to vocal learning biases and production in zebra finches. Such contributions can be revealed by examining acoustic patterns in the songs of birds raised without sensory exposure to song ("untutored birds") or of birds that are unable to hear from early in development ("early-deafened birds"). We observed that untutored zebra finches and early-deafened zebra finches produce songs with positional variation in some acoustic features (e.g., mean frequency) that resemble universal patterns observed in tutored birds. Similar to tutored birds, early-deafened birds also produced song motifs with alternation in acoustic features across adjacent syllables. That universal acoustic patterns are observed in the songs of both untutored and early-deafened birds highlights the contribution motor production biases to the emergence of universals in culturally transmitted behaviors.

It has long since suffered from the consequences of overexploitation of its resources, mainly fish stocks, and increasingly high pollution. The closure of 58% of the fish processing plants (FPPs) is attributed to the declining fish stocks due to overfishing and pollution in particular. The installation and operation of a pilot membrane bioreactor (MBR) in Kisumu, Kenya, adopts an integrated approach by providing an integral, sustainable, cost effective and robust solution for water sanitation which also meets the demand for clean water in fish processing industry, aquaculture and irrigation. The innovative system comprises a pilot MBR coupled with a recirculation aquaculture system (RAS). The RAS is able to recirculate 90-95% of its water volume; only the water loss through evaporation and drum filter back flushing has to be replaced. To compensate for this water deficit the MBR treats domestic wastewater for further reuse. Additionally, excess, purified water is used for irrigating a variety of local vegetables and could also be used in fish processing plants. The pilot-scale MBR plant with around 6 m2 submerged commercial polyethersulfone (PES) membranes provides treated water in basic agreement with FAO (Food and Agriculture Organization) standards for irrigation and aquaculture, showing no adverse effects on tilapia fingerlings production. A novel membrane module with a low-fouling coating is operating stably, but has not yet shown improved performance compared to the commercial one. This article is protected by copyright.

Due to their large drug uptake capacities and slow-release mechanisms, MOFs are desirable drug delivery vehicles that protect and transport sensitive drug molecules to target sites. The inclusion of other guest materials into MOFs to make MOF-composite materials has added further functionality, from externally triggered drug release to improved pharmacokinetics and diagnostic aids. MOF-composites are synthetically versatile and can include examples such as magnetic nanoparticles in MOFs for MRI image contrast and polymer coatings that improve the blood-circulation time. From synthesis to applications, this review will consider the main developments in MOF-composite chemistry for biomedical applications and demonstrate the potential of these novel agents in nanomedicine. We conclude that, although vast synthetic progress has been made in the field, it requires now to develop more biomedical expertise with a focus on rational model selection, a major comparative toxicity study, and advanced targeting techniques.

This progress has been achieved by the recent development of high throughput screening methods. We are all familiar with metabolites like sugars, amino acids, lipids or nucleotides. But there are many more of these small molecules. Metabolites include all intermediates and products of cellular metabolism. Metabolome refers to the whole collection of metabolites in a biological system. This article is protected by copyright.

We report four cases of COVID-19 in solid organ transplant recipients including recipients of kidney, liver, lung, and heart transplants. We describe each patient's medical history including transplantation history, their clinical presentation and workup, and their course from diagnosis to either hospital discharge or to improvement in symptoms. These reports demonstrate a range of symptoms, clinical severity, and disease course in solid organ transplant recipients with COVID-19, including two hospitalized patients and two patients managed entirely in the outpatient setting.

Tensile strain is known to improve the electrocatalytic activity of palladium electrodes for reduction of carbon dioxide or dioxygen, but determining how strain affects the hydrogen evolution reaction (HER) is complicated by the fact that palladium can absorb hydrogen concurrently with HER. We report here a custom electrochemical cell that applies tensile strain to a flexible working electrode that enabled us to resolve how tensile strain affects hydrogen absorption and HER activity for a thin film palladium electrocatalyst. When the electrodes were subjected to mechanically-applied tensile strain, the amount of hydrogen that absorbed into the palladium decreased, and HER electrocatalytic activity increased. BIRB 796 mw This study showcases how strain can be used to modulate the hydrogen absorption capacity and HER activity of palladium. © 2020 WILEY-VCH Verlag GmbH & Co.

Due to the intricate structure of DNA, visualization of the surface charge density of DNA nanostructures under physiological conditions was not previously possible. Here, we perform a simultaneous analysis of the topography and surface charge density of DNA nanostructures using atomic force microscopy and scanning ion conductance microscopy. The effect of in situ ion exchange using various alkali metal ions is tested with respect to the adsorption of DNA origami onto mica, and a quantitative study of surface charge density reveals ion exchange phenomena in mica as a key parameter in DNA adsorption. This is important for structure-function studies of DNA nanostructures. The research provides an efficient approach to study surface charge density of DNA origami nanostructures and other biological molecules at a single molecule level. © 2020 WILEY-VCH Verlag GmbH & Co.

This study explored whether maternal asthma in pregnancy is associated with the development of offspring microvascular structure and if it was related to biomarkers of angiogenesis in utero. Children aged 4 to 6 years, born to either asthmatic mothers (n=38) or healthy controls (n=25) had their retinal microvascular structure examined. Maternal plasma placental growth factor (PlGF) concentrations at 18 and 36 weeks gestation were measured. There was a significant global difference in all retinal microvascular measures between children of asthmatic mothers relative to controls and increased retinal venular tortuosity in children born to asthmatic mothers (7.1 (95% CI 0.7- 13.5); p=0.031). A rise in plasma PlGF from 18 to 36 weeks' gestation was observed in the control population which was significantly lower in the asthma group by 190.9 pg/mL. PlGF concentrations were correlated with microvascular structure including arteriolar branching and venular tortuosity. These exploratory findings indicate that exposure to maternal asthma during pregnancy is associated with persistent changes in microvascular structure in childhood that may be driven by alterations to angiogenic mechanisms in utero.

The rest of the country continued with the regular allocation policy (1). In Switzerland, which has more COVID-19 cases per capita than Italy (2), we have opted for a stepwise approach.

Lombardy has been the most affected region in Italy The current mortality rate of COVID-19 patients is 18,3% (10022 deaths) (April 10th) with hospitals in Lombardy having to expand the total number of ICU beds from 724 to 1381 to accommodate infected patients. There has been a drastic decrease in liver donors. From February 23rd until April 10th, 17 LTs were performed in Lombardy. Mean donor age was 49 years (range 18-74) whereas mean recipient age was 55 (13-69); mean MELD Score was 12 (6-24). All donors underwent screening for SARS CoV-2 prior to LT. Two patients tested positive after LT, and one patient died for COVID on POD 30. 16 patients are alive after an average of 30 days post LT (range 3-46). 10 patients have been discharged. This study has found no specific reason concerning the safety of recipients, to stop liver transplantation programmes.
