Insulin, the most potent anabolic hormone, is critical for somatic growth and metabolism in vertebrates. Type 2 diabetes, which is the primary cause of hyperglycemia, results from an inability of insulin to signal glycolysis and gluconeogenesis. Our previous study showed that double knockout of insulin receptor a (insra) and b (insrb) caused β-cell hyperplasia and lethality from 5 dpf to 16 dpf. In this study, we characterized the physiological roles of Insra and Insrb, in somatic growth and fueling metabolism, respectively...

Acute lung injury (ALI) and the acute respiratory distress syndrome (ARDS) are high-mortality and life-threatening diseases that are associated with neutrophil activation and accumulation within lung tissue. Emerging evidence indicates that neutrophil-platelet aggregates (NPAs) at sites of injury increases acute inflammation and contributes to the development of ALI. Even though numerous studies have increased our understanding of the pathophysiology of ALI, there is still a lack of innovative and useful treatments that reduce mortality, emphasizing that there is an urgent need for novel treatment strategies...

Acupuncture, including manual and electroacupuncture (MA and EA), at the P5-6 acupoints stimulates afferents in the median nerve (MN) to modulate sympathoexcitatory cardiovascular reflexes. Transient receptor potential vanilloid type-1 (TRPV1) is present in afferents distributed in the region of acupoints. However, contribution of TRPV1 to activation of sensory nerves by acupuncture, leading to modulation of pressor responses has not been studied. We hypothesized that TRPV1 participates in acupuncture's activation of sensory fibers and neurons to modulate pressor reflexes...

Zn2+ is an essential element for cell survival/growth, and its deficiency is linked to many disorders. Extracellular Zn2+ concentration changes participate in modulating fundamental cellular processes such as proliferation, secretion, ion transport, and cell signal transduction in a mechanism that is not well understood. Here, we hypothesize that the Zn-sensing receptor ZnR/GPR39, found in tissues where dynamic Zn2+ homeostasis takes place, enables extracellular Zn2+ to trigger intracellular signaling pathways regulating key cell functions in vascular cells...

MiR-199a is a novel gene regulator with an important role in inflammation and lung injury. However, its role in the pathogenesis of sepsis-induced acute respiratory distress syndrome (ARDS) is currently unknown. Our study explored the role of miR-199a in sepsis-induced ARDS and its mechanism of action. First, we found that LPS could up-regulate miR-199a in alveolar macrophages. Down-regulation of miR-199a inhibited the up-regulation of inflammatory cytokines in alveolar macrophages and induced the remission of histopathologic changes, the reduction of pro-inflammatory cytokines, and the up-regulation of apoptosis protein expression in an ARDS lung, showing a protective role for miR-199a...

RNAs may act as competing endogenous RNAs (ceRNAs), a critical mechanism in determining gene expression regulations in many cancers. However, the roles of ceRNAs in thyroid carcinoma remains elusive. In this study, we have developed a novel pipeline called Molecular Network-based Identification of ceRNA (MNIceRNA) to identify ceRNAs in thyroid carcinoma. MNIceRNA first constructs micro RNA (miRNA)-messenger RNA (mRNA)long non-coding RNA (lncRNA) networks from miRcode database and weighted correlation network analysis (WGCNA), based on which to identify key drivers of differentially expressed RNAs between normal and tumor samples...

Flow-induced crystallization (FIC) is a typical nonequilibrium phase transition and a core industry subject for the largest group of commercially useful polymeric materials: semicrystalline polymers. A fundamental understanding of FIC can benefit the research of nonequilibrium ordering in matter systems and help to tailor the ultimate properties of polymeric materials. Concerning the crystallization process, flow can accelerate the kinetics by orders of magnitude and induce the formation of oriented crystallites like shish-kebab, which are associated with the major influences of flow on nucleation, that is, raised nucleation density and oriented nuclei...

In this study, a series of Ge1-xMnxTe (x=0-0.21) compounds were prepared by melting-quenching-annealing process combined with Spark Plasma Sintering (SPS). The effect of alloying MnTe into GeTe on the structure and thermoelectric properties of Ge1-xMnxTe is profound. With increasing content of MnTe, the structure of the Ge1-xMnxTe compounds gradually changes from rhombohedral to cubic, and the known R3m to Fm-3m phase transition temperature of GeTe moves from 700 K closer to room temperature. First-principles density functional theory calculations show that alloying MnTe into GeTe decreases the energy difference between the light and heavy valence bands in both the R3m and the Fm-3m structures, enhancing a multi-band character of the valence band edge that increases the hole carrier effective mass...

Macrophage, a highly plastic population, is widely distributed. Macrophage functions are settled and acquired polarization programs in response to microenvironmental signals and involved in many inflammatory disorders, such as experimental autoimmune myocarditis (EAM). Phenotypic and functional changes in macrophage are considered as an important determinant of disease progression and/or regression. Angiotensin II (ANG II), as a powerful proinflammatory factor, plays critical roles in inflammatory diseases and macrophage recruitment...

Chronic hepatitis B virus (HBV) infection is the major cause of hepatocellular carcinoma (HCC). The pre-S2 mutant large HBV surface antigen (LHBS) is highly associated with HCC. This study aimed to analyze the expression of the large form of surface protein in tumors and to evaluate the LHBS with mutations within the pre-S2 region as a high-risk recurrence marker in HCC patients after curative hepatic resection. By the analyses of immunohistochemical staining (N = 12) and Western Blotting (N = 22), the HBV surface protein, which is mainly comprised of the major form of HBS, was greatly diminished in the tumors...

The bioremediation of polycyclic aromatic hydrocarbon (PAH)-contaminated sites is not running smoothly, because of the lower activity of PAH-degrading bacteria in actual bioremediation applications. The phenomenon of "viable but non culturable" (VBNC) state may be a main limiting factor for their poor biodegradation capabilities of PAHs. Due to their abilities of entering into the VBNC state, most of bacterial populations with PAH-degradation potential remain unculturable. Resuscitation of VBNC bacteria will enhance the degradation capability of indigenous bacteria which will eventually obtain their better capabilities in environmental bioremediation...

Hypoparathyroidism (HPT) is a rare disease with leading symptoms of hypocalcemia, associated with high serum phosphorus levels and absent or inappropriately low levels of parathyroid hormone (PTH). In patients with thalassemias it is mainly attributed to transfusional iron overload, and suboptimal iron chelation therapy. The main objectives of this survey were to provide data on the prevalence, demographic and clinical features of HPT in thalassemia major (TM) and intermedia (TI) patients living in different countries, and to assess its impact in clinical medical practice...

Although nanomedicines have been pursued for nearly 20 years, fundamental chemical strategies that seek to optimize both the drug and drug carrier together in a concerted effort remain uncommon yet may be powerful. In this work, two block polymers and one dimeric prodrug molecule were designed to be coassembled into degradable, functional nanocarriers, where the chemistry of each component was defined to accomplish important tasks. The result is a poly(ethylene glycol) (PEG)-protected redox-responsive dimeric paclitaxel (diPTX)-loaded cationic poly(d-glucose carbonate) micelle (diPTX@CPGC)...

Horizontal genes transfer (HGT) plays an important role in the dissemination of antibiotic resistance genes (ARGs) in the environment. However, the mechanisms of HGT of ARGs under the influence of antibiotics in sub-MIC remain rarely explored. Moreover, given its collective nature, HGT was considered to be relative to quorum sensing (QS) system. To investigate whether QS has any impact on horizontal gene transfer of ARGs, experiments were conducted to determine the conjugative efficiency of plasmid RP4 on Escherichia coli (E...

High levels of macrolide resistance and increasing fluoroquinolone resistance are found in Mycoplasma genitalium in many countries. We evaluated pristinamycin for macrolide-resistant M. genitalium in a sexual health center in Australia. Microbiologic cure was determined by M. genitalium-specific 16S PCR 14-90 days after treatment began. Of 114 persons treated with pristinamycin, infection was cured in 85 (75%). This percentage did not change when pristinamycin was given at daily doses of 2 g or 4 g or at 3 g combined with 200 mg doxycycline...

An example of Rh-catalyzed C-H activation with methyl trifluoroacrylate for the synthesis of fluoroolefins and heterocycles (benzoindolizines) is reported. The types of products were determined by the directing group. The benzoindolizines and fluoroolefins were obtained by using pyridine and pyrazole as the directing group, correspondingly. These transformations present a number of advantages, such as oxidant-free reaction conditions and broad functional group tolerance. Moreover, this reaction greatly extends the application of fluoroolefins...

Many experimental results reveal different activities among different low-index surfaces of photocatalysts. The current investigation focuses on theoretical understandings of the electronic characteristics, surface activity and stability of different low-index surfaces of BiVO4 towards water splitting using first-principles calculations. The results indicate that BiVO4 has four types of low-index surfaces, namely, the (010)T1, (010)T2, (110)T1, and (1 ̅11)T1. The different band edge potential of the surfaces, resulted from the variation of electrostatic potential, will lead to a higher oxidation ability for the (010)T1 and (010)T2 than (110)T1 and (1 ̅11)T1 surfaces...
