miRNA-10a is rhythmically expressed and regulates genes involved in lipid and glucose metabolism. However, the effects of miRNA-10a on obesity and glucose intolerance, as well as on the diurnal pattern of expression of circadian clock genes, remain unknown. We explored the effects of miRNA-10a-5p on insulin resistance and on the diurnal patterns of serum triglycerides and gut microbiota in high-fat diet- (HFD-) fed mice. The results showed that oral administration of miRNA-10a-5p significantly prevented body weight gain and improved glucose tolerance and insulin sensitivity in HFD-fed mice. Administration of miRNA-10a-5p also maintained the diurnal rhythm of Clock, Per2, and Cry1 expression, as well as serum glucose and triglyceride levels. Surprisingly, the diurnal oscillations of three genera of microbes, Oscillospira, Ruminococcus, and Lachnospiraceae, disrupted by HFD feeding, maintained by administration of miRNA-10a-5p. Xevinapant purchase Moreover, a strong positive correlation was found between hepatic Clock expression and relative abundance of Lachnospiraceae, both in control mice (r = 0.877) and in mice administered miRNA-10a-5p (r = 0.853). Furthermore, we found that along with changes in Lachnospiraceae abundance, butyrate content in the feces maintained a diurnal rhythm after miRNA-10a-5p administration in HFD-fed mice. In conclusion, we suggest that miRNA-10a-5p may improve HFD-induced glucose intolerance and insulin resistance through the modulation of the diurnal rhythm of Lachnospiraceae and its metabolite butyrate. Therefore, miRNA-10a-5p may have preventative properties in subjects with metabolic disorders.Chronic kidney disease is a common disease closely related to renal tubular inflammation and oxidative stress, and no effective treatment is available. Activation of the nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome is an important factor in renal inflammation, but the mechanism remains unclear. Micheliolide (MCL), which is derived from parthenolide, is a new compound with antioxidative and anti-inflammatory effects and has multiple roles in tumors and inflammatory diseases. In this study, we investigated the effect of MCL on lipopolysaccharide- (LPS-) induced inflammation in renal tubular cells and the related mechanism. We found that MCL significantly suppressed the LPS-induced NF-κB signaling and inflammatory expression of cytokines, such as tumor necrosis factor-α and monocyte chemoattractant protein-1 in a rat renal proximal tubular cell line (NRK-52E). MCL also prevented LPS- and adenosine triphosphate-induced NLRP3 inflammasome activation in vitro, as evidenced by the inhibition of NLRP3 expression, caspase-1 cleavage, and interleukin-1β and interleukin-18 maturation and secretion. Additionally, MCL inhibited the reduction of mitochondrial membrane potential and decreases the release of reactive oxygen species (ROS). Moreover, MCL can prevent NLRP3 inflammasome activation induced by rotenone, a well-known mitochondrial ROS (mROS) agonist, indicating that the mechanism of MCL's anti-inflammatory effect may be closely related to the mROS. In conclusion, our study indicates that MCL can inhibit LPS-induced renal inflammation through suppressing the mROS/NF-κB/NLRP3 axis in tubular epithelial cells.A set of novel, easily synthesized aluminum complexes, Al[κ2-N,N-2-(methylamino)pyridine]2R (R = Et, iBu) are reported. When subjected to 1 atm of CO2 pressure, each hemilabile pyridine arm dissociates and facilitates cooperative activation of the CO2 substrate reminiscent of a Frustrated Lewis Pair. This reaction has limited precedent for Al/N based Lewis Pair systems, and this is the first system readily shown to sequester multiple equivalents of CO2 per aluminum center. The ethyl variant then reacts further, inserting a third equivalent of CO2 into the aluminum alkyl to generate an aluminum carboxylate. Examples of this type of reactivity are rare under thermal conditions. A joint experimental/computational study supports the proposed reaction mechanism.In this study, taxonomic and phylogenetic analyses of Junghuhnia were performed. Three new species were characterised according to morphological characteristics and molecular phylogenetic analysis using ITS and nLSU sequences. They are J. austrosinensissp. nov., J. nandinaesp. nov. and J. subcollabenssp. nov.Junghuhnia austrosinensis is characterised by resupinate, thin basidiomata with white to buff-yellow hymenophore, small pores (9-11 per mm), clamped generative hyphae possessing hymenial cystidia, ellipsoid basidiospores (2.5-3 × 1.7-2 µm) and growth on fallen bamboo or angiosperm branch. Junghuhnia nandinae is characterised by resupinate basidiomata with pink to salmon pores and a distinct white margin, clamp generative hyphae, interwoven tramal hyphae, ellipsoid basidiospores measuring 2.6-3.2 × 1.8-2 µm and growth on Nandina domestica. Junghuhnia subcollabens is characterised by resupinate basidiomata with pale salmon to brownish vinaceous hymenophore, small pores (10-12 per mm), generative hyphae with simple septa and clamp connections, interwoven tramal hyphae, lunate basidiospores measuring 2.9-3.4 × 1.6-1.8 µm and thriving on rotten wood of angiosperms.
The Mediterranean basin is known to be the cradle of many endemic species. Within mayflies (Insecta, Ephemeroptera), North African species belonging to the family Baetidae remain poorly known and, traditionally, affinities to European fauna were proposed. Recent studies, based on molecular reconstructions, showed closer relationships to Mediterranean islands fauna.

Baetidae were sampled from North-West Algerian wadis (Tafna basin) and involved in COI barcoding reconstructions. Seven species were identified. The subgenus Rhodobaetis is represented by
known previously from Macaronesian islands, Europe and Morocco and the Maghrebian endemic
. Specimens, previously identified as Cloeon cf. dipterum, correspond to
and, until now, only reported from Macaronesia. Besides the confirmation of endemicity of some species, such as
and
, our molecular study showed quite original results for relationships between European, insular and Algerian species.
stood out as a North African endemic sister clade tnsular and Algerian species. Baetis maurus stood out as a North African endemic sister clade to an Iberian clade. Furthermore, we found clear interspecific distances between Algerian and European clades for A. cf. sinaica and B. cf. pavidus, suggesting the presence of cryptic species in Algeria. However, additional studies are needed, as, for the moment, no clear morphological characters were found to separate the different clades and support them as valid species.Work on the catalogue of type specimens of vascular plants deposited in the KRAM herbarium has highlighted uncertainties and errors in references to place of valid publication of numerous taxa described by Hugo Zapałowicz in his Conspectus florae Galiciae criticus - Krytyczny przegląd roślinności Galicyi (1904-1914). Zapałowicz published his work in an excerpt series, a serial publication and a multi-volume book, with much duplication amongst these three different forms. Despite the importance of this work, no studies have clarified the dates of publication of its various parts, as relevant to the nomenclature of numerous new taxa of Central European vascular plants described therein 94 species and hybrids, 10 subspecies and more than 2000 other infraspecific taxa. Here, the publication dates of the component parts of Zapałowicz's work are clarified and discussed. Archival sources that made it possible to determine publication dates of these works are described in detail.Niviventer confucianus sacer Thomas, 1908, which has been regarded as a subspecies of N. confucianus, was found to be a distinct species from N. confucianus based on molecular, karyotyping, and morphological characteristics in this study. Niviventer c. sacer was found to belong to a distinct phylogenetic clade in phylogenetic tree constructed using the mitochondrial gene Cytb, it clustered with N. bukit (Bonhote, 1903) from Vietnam and N. confucianus (Milne-Edwards, 1871) from Yunnan, but showed a distant relationship with N. confucianus from adjacent areas. The genetic distance between N. c. sacer and N. confucianus was more than 5.8%, reaching the level of interspecific differentiation. link2 The species delimitation indicates that N. c. sacer is a monophyletic group. The karyotype of N. c. sacer (FN = 55, 8m+4st+32t+X(sm)Y(t)) differed from that of N. confucianus (FN = 59, 6m+4sm+2st+32t+X(sm)Y(t)). In terms of morphological features, the length of incisive foramen (LIF) and length of auditory bulla (LAB) of N. c. sacer is significantly larger than that of N. confucianus and N. bukit (P less then 0.05) and the proportion of white tail tip to total tail length is significantly longer at N. c. sacer (≥ 1/3) than that at N. confucianus (≤ 1/3). Therefore, integrated analysis confirmed that N. link3 c. sacer is a distinct species of genus Niviventer rather than a subspecies of N. confucianus or N. bukit, namely N. sacer, which is only distributed in Shandong.A new species of Acanthosaura from Yunnan, China, is described based on morphological and genetic data. The new species can be separated from all other species of the genus by having a different shape of the black eye patch, a different coloration of the postorbital and occipital spines and nuchal crest, and a different color of the gular pouch. Genetically, uncorrected sequence divergences of COI between the new species and investigated congeners ranged from 16.12% to 24.11%. The conservation status of the new species is also discussed.Eidophasia assmannisp. nov., a new species of Plutellidae from the alpine zone of Russian Altai Mountains, is described from diagnostic morphology and DNA barcodes. Male adult and genitalia are illustrated, whereas the female sex remains unknown. The species inhabits alpine scree with patchy herbaceous plants and is considered as possible endemic species of the Altai Mountains. An updated checklist of the 13 global Eidophasia Stephens, 1842 species is provided. The likely polyphyly of the genus is discussed from molecular data of the barcode region of the mt COI gene.Dissomphalus is a cosmopolitan genus of Bethylidae and has 269 Neotropical species divided into 32 species-groups, mostly defined by the genital and the tergal process structures. Dissomphalus rectilineus and D. concavatus are sympatric species in the ulceratus species-group. Members of the species-group share many similarities in the morphology of the head, hypopygium, tergal process and genitalia, but may be distinguished by the structure of the hypopygium. Previous studies have found intermediate structures of the hypopygium in the sympatric areas and raised questions about the distinctiveness of these two species. We sequenced 340 bp of the mitochondrial gene cytochrome oxidase I of 29 specimens from Brazil and Paraguay, calculated the genetic divergence among specimens, and recovered the phylogenetic relationships between taxa. In addition, we compared the morphology of the hypopygium to evaluate its use as a species-specific diagnostic character using the genetic divergence values. We recovered three well-supported monophyletic groups (intraclade divergence from 1.
