Advanced techniques for overcoming problems encountered during in situ electron holography experiments in which a voltage is applied to an ionic conductor are reported. The three major problems encountered were 1) electric-field leakage from the specimen and its effect on phase images, 2) high electron conductivity of damage layers formed by the focused ion beam method, and 3) chemical reaction of the specimen with air. The first problem was overcome by comparing experimental phase distributions with simulated images in which three-dimensional leakage fields were taken into account, the second by removing the damage layers using a low-energy narrow Ar ion beam, and the third by developing an air-tight biasing specimen holder...

The synthesis of a series of CgPAr ligands is reported, where CgP is the 6-phospha-2,4,8-trioxa-1,3,5,7-tetramethyladamant-6-yl moiety and Ar = 2-pyridyl (L2), 3-pyridyl (L3), 2-pyrimidyl (L4), 4-R-2-pyridyl [R = Me (L5a), CF3 (L6a), SiMe3 (L7a)] or 6-R-2-pyridyl [R = Me (L5b), CF3 (L6b), SiMe3 (L7b). Testing of these ligands in the Pd-catalysed methoxycarbonylation of phenylacetylene reveals that the activity and branched selectivity of the catalysts derived from these ligands varies as a function of the N-heterocycle, with the catalyst derived from L5b being the most active of those tested...

Activin B is induced in response to inflammation in the liver and enhances hepcidin expression, but the source of activin B and the molecular mechanism underlying hepcidin induction are not clear yet. Lipopolysaccharide (LPS)-induced inflammation induced inhibin βB but not inhibin α or inhibin βA expression in the liver, implicating activin B induction. Immunoreactive inhibin βB was detected in endothelial cells and Kupffer cells in LPS-treated liver. Activin B, but not activin A or activin AB, directly increased hepcidin expression...

Allergic rhinitis is one of the most common health problems with a major effect on the quality of life. We intended to treat Allergic Rhinitis (AR) in patients who are either unresponsive to antihistamines or their job requires optimal alertness that may be disturbed by antihistamine's side effects and those who do not comply with the regular use. We tried short term phototherapy and evaluated its effect on AR. As phototherapy is effective in the treatment of atopic dermatitis (AD) and the same allergens can produce both AD and AR, phototherapy is proposed as a new tool in the AR treatment...

Mosquitoes act as vectors of key pathogens and parasites. Plant essential oils have been recognized as important sources of biopesticides, which do not induce resistance and have limited toxic effects on human health and non-target organisms. In this research, we evaluated the larvicidal and oviposition deterrence activity of Hedychium larsenii essential oil (EO) and its major compounds ar-curcumene and epi-β-bisabolol. Both molecules showed high toxicity against early third instars of Anopheles stephensi (LC50=10...

The aims of this study were to describe the internal and external match load (ML) of refereeing activity during official matches and also to investigate the relationship among the methods of ML quantification across a competitive soccer season. A further aim was to examine the usefulness of differential perceived exertion (dRPE) as a tool for monitoring internal ML in soccer referees. Twenty field referees (FR) and 43 assistant referees (AR) participated in this study. Data were collected from 30 competitive matches (FR = 20 observations, AR = 43 observations) and included measures of internal (Edwards' heart rate derived training impulse [TRIMPEDW]), external (total distance covered [TD], distance covered at high speeds [HSR] and player load [PL]) ML, differentiated ratings of perceived respiratory [sRPEres ML] and leg muscle [sRPEmus ML] exertion)...

REVIEW

Molecular and histopathological profiling have classified breast cancer into multiple sub-types empowering precision treatment. Although estrogen receptor (ER) and human epidermal growth factor receptor (HER2) are the mainstay therapeutic targets in breast cancer, the androgen receptor (AR) is evolving as a molecular target for cancers that have developed resistance to conventional treatments. The high expression of AR in breast cancer and recent discovery and development of new nonsteroidal drugs targeting the AR provide a strong rationale for exploring it again as a therapeutic target in this disease...

Allergic rhinitis (AR) is an IgE-mediated upper airway disease, and its impact on asthma has been widely recognized. Protein tyrosine phosphatase non-receptor 22 (PTPN22) gene and the cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) gene polymorphisms have been reported to be associated with several immune-related diseases. Here we investigated the reffect of these two genes' polymorphisms on the risk of AR and asthma in Chinese Han children. A total of 106 AR patients, 112 AR with asthma patients, and 109 healthy children were enrolled in the study...

Both survival of motor neuron (SMN) genes are associated with spinal muscular atrophy; mutations in SMN1 cause the disease, and SMN2 modulates its severity. It is established that different alternative splicing of exon 7 occurs for SMN1 and SMN2, and a cryptic exon was recently found in intron 6 of both genes. Here, we characterize this cryptic exon and clarify its alternative splicing pattern in control and spinal muscular atrophy cells.

Fossil elytra of a small trechine carabid are reported from the Oliver Bluffs on the Beardmore Glacier at lat. 85°S. They were compared with counterparts from the extant genera Trechisibus, Tasmanorites, Oxytrechus and Pseudocnides. The fossils share some characters but are sufficiently different to be described as a new genus and species. We named the new species Antarctotrechus balli in honour of George E. Ball who made major contributions to the study of carabids through his own research and the training of students while at the University of Alberta, Edmonton, Alberta, Canada...

Patients with castration-resistant prostate cancer (CRPC) often are treated with drugs that target the androgen receptor (AR) ligand-binding domain. Constitutively active AR splice variant 7 (AR-V7) lacks the ligand-binding domain and, if detected in circulating tumor cells, may be associated with resistance to these agents. We validated an AR-V7 assay in a Clinical Laboratory Improvement Amendments (CLIA)-certified laboratory. Circulating tumor cells were isolated, and mRNA was reverse-transcribed into cDNA...

PURPOSE: Overactive bladder (OAB) causes urinary urgency, usually accompanied by frequency and nocturia. Alpha 1-adrenergic receptor (α1-AR) antagonists are known to improve lower urinary tract symptoms associated with OAB. The α1-AR antagonists constitute a variety of drugs according to the receptor subtype affinity. This study investigated the efficacy of tamsulosin, naftopidil, and a combination of the two on OAB rats. METHODS: The OAB rat model was induced by an intraperitoneal injection of cyclophosphamide for 14 days...

Recent evidence suggests that a high-fat diet (HFD) plays an important role in prostate carcinogenesis; however, underlying mechanisms largely remain unknown. Here, we investigated microRNA (miRNA) expression changes in murine prostate cancer (PCa) xenografts using two different diets: HFD and control diet. We then assessed the roles and targets of altered miRNAs in HFD-induced PCa progression. We identified 38 up- and 21 downregulated miRNAs in xenografts under HFD conditions using the miRCURY LNA™ microRNA array...

Small mammals have the ability to enter torpor, a hypothermic, hypometabolic state, allowing impressive energy conservation. Administration of adenosine or adenosine 5'-monophosphate (AMP) can trigger a hypothermic, torpor-like state. We investigated the mechanisms for hypothermia using telemetric monitoring of body temperature in wild type and receptor knock out (Adora1(-/-)-/-, Adora3(-/-)) mice. Confirming prior data, stimulation of the A3 adenosine receptor (AR) induced hypothermia via peripheral mast cell degranulation, histamine release, and activation of central histamine H1 receptors...

Apical revascularization (AR) and platelet-rich plasma have been used to restore dental pulp vitality in infected immature permanent teeth. Two regenerative therapies are cell transplantation and cell homing. This article updates and benchmarks these therapies with cell homing. A case report concluded that AR increased root length; however, quantitative and statistical assessments disproved this. Regenerative endodontic therapies require prospective clinical trials demonstrating safety and efficacy. These therapies are intrinsically susceptible to procedural and patient variations...

Atomic clusters can serve as ideal model systems for exploring ultrafast (∼100 fs) laser-driven ionization dynamics of dense matter on the nanometer scale. Resonant absorption of optical laser pulses enables heating to temperatures on the order of 1 keV at near solid density conditions. To date, direct probing of transient states of such nano-plasmas was limited to coherent x-ray imaging. Here we present the first measurement of spectrally resolved incoherent x-ray scattering from clusters, enabling measurements of transient temperature, densities, and ionization...
