We also find that mouse and human striatal regions are strongly conserved, with the mouse caudoputamen exhibiting an equal degree of similarity to both the human caudate and putamen.Tribocatalysis, as a new approach in environmental purification, has drawn increasing attention in the past few years. In this work, we successfully convert mechanical energy to chemical energy by Bi12TiO20, which was synthesized by a hydrothermal method. Under magnetic stirring, electrons transfer from the surface of Bi12TiO20 to the polytetrafluoroethylene-sealed magnetic bar due to their friction. Moreover, the holes that remain on Bi12TiO20 provide oxidation properties in the process for organic matter degradation. According to a series of tests, it is noticed that the shape of the stirring bar and the material of the reaction vessel have a remarkable influence on the removal efficiency of contaminants. Simultaneously, multiple tests reveal the high stability of Bi12TiO20. A great potential for Bi12TiO20 to control water pollutants under dark conditions during collection of ambient mechanical energy was clearly demonstrated in this study.The α2δ3 auxiliary subunit of voltage-activated calcium channels is required for normal synaptic transmission and precise temporal processing of sounds in the auditory brainstem. In mice its loss additionally leads to an inability to distinguish amplitude-modulated tones. Furthermore, loss of function of α2δ3 has been associated with autism spectrum disorder in humans. To investigate possible alterations of network activity in the higher-order auditory system in α2δ3 knockout mice, we analyzed neuronal activity patterns and topography of frequency tuning within networks of the auditory cortex (AC) using two-photon Ca2+ imaging. Compared to wild-type mice we found distinct subfield-specific alterations in the primary auditory cortex, expressed in overall lower correlations between the network activity patterns in response to different sounds as well as lower reliability of these patterns upon repetitions of the same sound. Higher AC subfields did not display these alterations but showed a higher amount of well-tuned neurons along with lower local heterogeneity of the neurons' frequency tuning. Our results provide new insight into AC network activity alterations in an autism spectrum disorder-associated mouse model.The growing interest in porcine coronaviruses (CoVs) is due to both their negative effect on the swine industry and their propensity to mutate and overcome host barriers. Since information on CoVs in wild boar (Sus scrofa) is limited, especially in Italy, a serosurvey was conducted to assess the epidemiologic situation in the Campania region and to clarify the role of wild boar as reservoirs for enteric (porcine epidemic diarrhea virus [PEDV], transmissible gastroenteritis virus [TGEV]) and respiratory (respiratory coronavirus [PRCV]) swine CoVs. During the 2016-17 hunting season, serum samples were collected from 444 wild boars and tested for antibodies to enteric (PEDV, TGEV) and respiratory (PRCV) porcine CoVs by enzyme-linked immunosorbent assay. The highest seroprevalence in wild boars was for PEDV, with a positivity of 3.83% (95% confidence interval [CI] 2.05-5.6), whereas very low seroprevalences were found for TGEV and PRCV (0.67% positivity; 95% CI 0-1.44 in both cases). There was no statistical association between seropositivity to CoVs, sex, and location, whereas the prevalence of seropositive animals was positively correlated with young age (0-12 mo old). Our data confirm the presence of CoVs in wild boars in the Campania region. Our data are in agreement with the results of similar studies from other European countries, which attribute a minor role to wild boar in the transmission of these infections to domestic pigs. Our results suggest that continuous serologic surveys are necessary to monitor wild animals and detect emerging threats to livestock and humans.Herein, we report carbene-mediated benzannulation of vinyl sulfoxonium ylides with electron-deficient alkynes and alkenes to synthesize oxygenated arenes. This protocol features excellent regioselectivity, a broad substrate scope, and mild reaction conditions. Mechanistic studies revealed that the reaction proceeds through furan generation, cycloaddition, ring cleavage, and aromatization cascades. The synthesized arenes have been utilized in diverse product transformations and arene ring homologation.Among the known hydrosilylation or carbosilylation conditions of alkynes, anti-addition of the two units across the triple bond is considered rare compared to the syn counterpart. For anti-silylative vicinal difunctionalizations, transition-metal catalysts, such as ruthenium or palladium complexes, are generally required. Accordingly, silyl alkali metals have not been employed for those anti-addition transformations. Here we demonstrate that silyllithiums can add across the triple bond of a series of propargylic alkoxides regioselectively in an anti-fashion. Upon treatment with a variety of electrophiles, the trisubstituted alkenyl lithium intermediates were transformed into highly functionalized β-silyl allylic alcohols with high regiocontrol, eventually providing tri- or tetrasubstituted alkenylsilanes stereoselectively. A classic trick for anti-addition with propargylic alkoxides has transformed anti-silylative functionalizations into a robust and reliable strategy.Since the interfacial binding strength and structural integrity have a strong influence on the active sites of nanocomposites, this study focused on exploring the structural and electronic properties at the interface between the implanted metal ion and host support. For this, nanocomposites of gold embedded in CeO2-ZrO2 and CeO2-Al2O3 matrices were fabricated, and their structural and morphological properties were investigated using ICP-OES, UV-vis, XRD, Raman, HRTEM, and high-resolution XPS studies and compared. From the results, it was found that the deposition of gold is highly favored over CeO2-ZrO2 (3.99 atomic %) than CeO2-Al2O3 (1.21 atomic %); however, the same amount of gold was used for the synthesis of both nanocomposites, as befits it. The HRTEM images of Au/CeO2-ZrO2 displayed well-organized yarn textured particles with less than 5 nm size, which lacks in Au/CeO2-Al2O3. The reason for this less systematized and less Au embedding in the presence of alumina in CeO2-Al2O3 was verified with the high-rence of less-desired γ-Al2O3 phases. These characteristics of Au/CeO2-ZrO2 ensured its performance as a promised photocatalyst for thioanisole degradation without using any harmful oxidants, and its stability towards different irradiation conditions, such as visible, ultraviolet, and solar light.Studies on the hydration properties, proton conductivity, and water content of perfluorinated ionomer thin films at temperatures relevant to fuel cell operation temperatures (around 80 °C) and the effect of ionomer chemistry are scarce. In this work, we report the water content and proton conductivity properties of thin-film ionomers (30 nm) at 80 °C over a wide range of relative humidity (0-90%) for seven different ionomers differing in the side-chain structure, including the number of protogenic groups, with the equivalent weight ranging from 620 to 1100 g/mol of sulfonic acid. The results show that the acid content or equivalent weight of the ionomer is the strongest determinant of both the swelling and the proton conductivity of ionomer films at a given relative humidity. The molar water content (λ) of ionomer films normalized to the molar protogenic group is observed to be equivalent-weight-dependent, implying that the affinity for water is acid-content-dependent. At high relative humidity conditions (>70%) pertinent to fuel cell operations, the proton conductivity of low-equivalent-weight ionomers was higher than that of higher-equivalent-weight ionomers. However, upon correlating the proton conductivity with molar water content (λ), the differences reduce dramatically, highlighting that water content is the controlling factor for proton conduction. Significantly higher values of both water content and proton conductivity are observed at 80 °C compared to those at 30 °C, implying that room temperature data are not reliable for estimating ionomer properties in the fuel cell catalyst layer.Deuteration of arylthianthren-5-ium triflates with CD3OD or CD3OD/CD3COCD3 in the presence of Cs2CO3 by palladium catalysis or photoirradiation allowed the convenient synthesis of deuterated arenes in good yields. The Pd-catalyzed reaction generally gave better yields than the photoinduced deuteration, but exceptions also exist. They could complement each other in some cases. These reactions featured eco-friendly conditions, simplicity, inexpensive deuterium sources, good functional group tolerance, and a range of substrates. Since arylthianthren-5-ium salts could be readily synthesized from arenes and thianthrene 5-oxide, this protocol provided a formal aromatic C-H deuteration with high selectivity, enabling efficient deuterium labeling of multifunctionalized arenes and drug molecules.Mammalian taxonomies are conventionally defined by morphological traits and genetics. How species differ in terms of neural circuits and whether inter-species differences in neural circuit organization conform to these taxonomies is unknown. The main obstacle to the comparison of neural architectures has been differences in network reconstruction techniques, yielding species-specific connectomes that are not directly comparable to one another. Here, we comprehensively chart connectome organization across the mammalian phylogenetic spectrum using a common reconstruction protocol. We analyse the mammalian MRI (MaMI) data set, a database that encompasses high-resolution ex vivo structural and diffusion MRI scans of 124 species across 12 taxonomic orders and 5 superorders, collected using a unified MRI protocol. We assess similarity between species connectomes using two methods similarity of Laplacian eigenspectra and similarity of multiscale topological features. We find greater inter-species similarities among species within the same taxonomic order, suggesting that connectome organization reflects established taxonomic relationships defined by morphology and genetics. see more While all connectomes retain hallmark global features and relative proportions of connection classes, inter-species variation is driven by local regional connectivity profiles. By encoding connectomes into a common frame of reference, these findings establish a foundation for investigating how neural circuits change over phylogeny, forging a link from genes to circuits to behaviour.Background Fucoidans extracted from sea cucumber Pearsonothuria graeffei (fuc-Pg) are rich in 4-O-sulfation, and have been shown to be potential functional polysaccharides for preventing metabolic syndromes. Objective The present study was conducted to investigate the effect of fuc-Pg on the prevention of obesity and its underlying mechanism. Method Mice were fed a normal diet, high-fat diet (HFD), HFD plus low and high dosage of fuc-Pg, and HFD plus simvastatin for 8 weeks. Results fuc-Pg intervention could significantly decrease weight gain and fat accumulation in the HFD-fed mice. Moreover, fuc-Pg improved serum lipid profile by decreasing serum concentrations of TG, TC, LDL-C, sCD36, ApoB48, and ApoB100 compared with the HFD group. HFD-induced upregulation of intestinal CD36, FABP-1, P-ERK1, and the ratio of p-ERK/ERK was reversed by the fuc-Pg treatment. Moreover, fuc-Pg improved the normal function of white adipose tissue by increasing the expression of UCP1, PPAR-γ, and PGC-1α in the HFD-fed mice. Furthermore, fuc-Pg alleviated systemic inflammation by reducing serum pro-inflammatory factors and breaking the TLR4/NF-κB pathway in both the colon and liver.
