Coxiella burnetii is a Gram-negative intracellular pathogen and is the causative agent of the zoonotic disease Q-fever. To cause disease, C. burnetii requires a functional type IVB secretion system (T4BSS) to transfer effector proteins required for the establishment and maintenance of a membrane bound parasitophorous vacuole (PV) and further modulation of host cell process. However, it is not clear how the T4BSS interacts with the PV membrane since neither a secretion pilus nor an extracellular pore forming apparatus has not been described...

We report high-temperature superconductivity in B-doped amorphous quenched carbon (Q-carbon). This phase is formed after nanosecond laser melting of B-doped amorphous carbon films in a super undercooled state and followed by rapid quenching. Magnetic susceptibility measurements show the characteristics of type-II Bardeen-Cooper-Schrieffer superconductivity with a superconducting transition temperature (Tc) of 36.0±0.5 K for 17.0±1.0 atomic percent boron concentration. This value is significantly higher than the best experimentally reported Tc of 11 K for crystalline B-doped diamond...

The relationship between blood pressure variability (BPV) and stroke recurrence is controversial. This study aimed to evaluate the predictive value of short-term and long-term BPV for stroke recurrence. The data from blood pressure and clinical outcome in TIA or ischemic stroke (BOSS) study included participants with acute ischemic stroke or transient ischemic attack (TIA) within 7 days after onset. Short-term BPV was measured by 24-h ambulatory BP measurement during hospitalisation. Long-term BPV, based on home blood pressure measurement, was measured by patients or their families from discharge to 90 days after qualifying events onset (twice daily)...

Co3O4-δ quantum dots (Co3O4-δ-QDs) with a crystallite size of approximately 2 nm and oxygen vacancies were fabricated through multicycle lithiation/delithiation of mesoporous Co3O4 nanosheets. Used as an oxygen evolution reaction (OER) electrocatalyst for water splitting, the catalytic performance (an overpotential of 270 mV@10 mA cm-2 and no decay within 30 h) of Co3O4-δ-QDs is superior to that of previously reported Co-based catalysts and the state-of-the-art IrO2. Compared with the Co3O4 nanosheets, the enhanced OER activity of Co3O4-δ-QDs is attributed to two factors: one is the increased quantity of the Faradaic active sites, including the total active sites (q*Total), the most accessible active sites (q*Outer) and their ratio (q*Outer/q*Total); the other is the enhanced intrinsic electroactivity per active site evaluated by the turnover frequency (TOF) and the current density normalized by the most accessible active sites (j/q*Outer) related to OER...

Previous research has shown the impact of the emotional dimension of nouns (i.e., valence and arousal) on the completion of relative clauses (RC) that are preceded by a double antecedent [e.g.,: Someone shot the servant (the first noun phrase, NP1) of the actress (the second noun phrase, NP2) who was on the balcony] (Fraga et al. in Q J Exp Psychol 65:1740-1759, 2012). The present study explored for the first time the role of emotional valence, specifically emotional positive nouns, on RC disambiguation in a self-paced reading experiment...

17-Ethinyl-3,17-dihydroxyandrost-5-ene (EAD) is an agent designed for the treatment of acute radiation syndrome (ARS). Given its vital role played in the prevention and mitigation of ARS, the development of a sharp, sensitive and robust liquid chromatography tandem mass spectrometry (LC-MS/MS) method to monitor the metabolism of EAD in vivo was crucial. A new method was constructed and validated for the determination of EAD with the internal standard of androst-5-ene-3β,17β-diol (5-AED). The blood samples were precipitated with methanol, centrifuged, from which the supernatant was separated on UPLC with C18 column and eluted in gradient with acetonitrile and Milli-Q water both containing 0...

The cardiac troponin C (TnC)-A8V mutation is associated with hypertrophic and restrictive cardiomyopathy (HCM and RCM) in human and mice. The residue affected lies in the N-helix, a region known to affect Ca(2+)-binding affinity to the N-terminal domain. Here we report on the functional effects of this mutation in skinned papillary muscle fibers from homozygous knock-in TnC-A8V mice. Muscle fibers from left ventricle were activated at 25°C under the ionic conditions of working cardiomyocytes. The pCa-tension relationship showed a 3× increase in Ca(2+)-sensitivity and a decrease (0...

Claudins provide tight junction barrier selectivity. The human CLDN5 gene contains a high-frequency single-nucleotide polymorphism (rs885985), where the G allele codes for glutamine (Q) and the A allele codes for an amber stop codon. Thus, these different CLDN5 alleles define nested open reading frames (ORFs) encoding claudin-5 proteins that are 303 or 218 amino acids in length. Interestingly, human claudin-16 and claudin-23 also have long ORFs. The long form of claudin-5 contrasts with the majority of claudin-5 proteins in the National Center for Biotechnology Information protein database, which are less than 220 amino acids in length...

The realization of long-range ferromagnetic order in two-dimensional van der Waals crystals, combined with their rich electronic and optical properties, could lead to new magnetic, magnetoelectric and magneto-optic applications. In two-dimensional systems, the long-range magnetic order is strongly suppressed by thermal fluctuations, according to the Mermin-Wagner theorem; however, these thermal fluctuations can be counteracted by magnetic anisotropy. Previous efforts, based on defect and composition engineering, or the proximity effect, introduced magnetic responses only locally or extrinsically...
