Over the years, the silkworm, Bombyx mori, has been manipulated by means of chemical and genetic approaches to improve silk production both quantitatively and qualitatively. The silk is produced by the silk gland, which degenerates quickly once the larva has finished spinning the cocoon. Thus, interfering with this degeneration process could help develop new technologies aimed at ameliorating silk yield. To this end, in this work we studied the cell death processes that lead to the demise of posterior silk gland of B...

The Juno spacecraft acquired direct observations of the jovian magnetosphere and auroral emissions from a vantage point above the poles. Juno's capture orbit spanned the jovian magnetosphere from bow shock to the planet, providing magnetic field, charged particle, and wave phenomena context for Juno's passage over the poles and traverse of Jupiter's hazardous inner radiation belts. Juno's energetic particle and plasma detectors measured electrons precipitating in the polar regions, exciting intense aurorae, observed simultaneously by the ultraviolet and infrared imaging spectrographs...

Structure based design and synthesis of pyrimidine containing reversible epidermal growth factor receptor (EGFR) inhibitors 1a-d are reported. The compounds (1a-d) inhibited the EGFR kinase activity in vitro with IC50 range 740 nM to 3 μM. mRNA expression of EGFR downstream target genes i.e. twist, c-fos and aurora were found to be altered upon treatment with compounds 1a-d. The compounds 1a-d exhibited excellent anticancer activity at low micromolar level (3.2-9 μM) in lung, colon and breast cancer cell lines...

Hepcidin is the main regulator of iron homeostasis and dysregulation of proteins involved in iron metabolism has been associated with tumorogenesis. However, to date, no epidemiological study has researched the association between hepcidin levels and gastric cancer risk. To further investigate the relationship between hepcidin levels and gastric cancer risk, we conducted a nested case-control study (EURGAST) within the multicentric European Prospective Investigation into Cancer and Nutrition (EPIC) study. The study included 456 primary incident gastric adenocarcinoma cases and 900 matched controls that occurred during an average of 11 years of follow-up...

Reducing the levels of the androgen receptor (AR) is one of the most viable approaches to combat castration-resistant prostate cancer (CRPC). Previously, we observed that proteasomal-dependent degradation of AR in response to 2-methoxyestradiol (2-ME) depends primarily on the E3 ligase C-terminus of HSP70-interacting protein (STUB1/CHIP). Here, 2-ME stimulation activates CHIP by phosphorylation via Aurora kinase A (AURKA). Aurora A kinase inhibitors and RNAi knockdown of Aurora A transcript selectively blocked CHIP phosphorylation and AR degradation...

During cell division, genome inheritance is orchestrated by microtubule attachments formed at kinetochores of mitotic chromosomes. The primary microtubule coupler at the kinetochore, the Ndc80 complex, is regulated by Aurora kinase phosphorylation of its N-terminal tail. Dephosphorylation is proposed to stabilize kinetochore-microtubule attachments by strengthening electrostatic interactions of the tail with the microtubule lattice. Here, we show that removal of the Ndc80 tail, which compromises in vitro microtubule binding, has no effect on kinetochore-microtubule attachments in the Caenorhabditis elegans embryo...

INTRODUCTION: Little is known about the prevalence of kidney diseases according to renal biopsy in Israel. Since updated literature worldwide emphasizes changing etiologies of chronic kidney disease, it is crucial to research and define the epidemiology and pathology of kidney disease in Israel. Hereby, we introduce an original review of the prevalence of kidney diseases in our study population, which we believe reflects the prevalence of kidney diseases in the population of Israel. AIMS: To investigate the prevalence of kidney diseases diagnosed by renal biopsy, according to age, gender, race and clinical symptoms...

A strong relationship between abnormal functions of Aurora kinases and tumorigenesis has been reported for decades. Consequently, Aurora kinases serve as potential targets for anticancer agents. Here, we identified aminobenzothiazole derivatives as novel inhibitors of Aurora B kinase through bioisosteric replacement of the previous inhibitors, aminobenzoxazole derivatives. Most of the urea-linked aminobenzothiazole derivatives showed potent and selective inhibitory activity against Aurora B kinase over Aurora A kinase...

Pulmonary fibrosis (PF) is the most common and aggressive interstitial lung disease, characterized by a patchy development of fibrosis leading to progressive destruction of the normal lung architecture which is preceded by an inflammatory process. Gene expression studies are important to understand the development of PF but the accuracy and reproducibility of Real-Time PCR depend on appropriate normalization strategies. This study aimed to analyze the expression variability of eight commonly used reference genes during the initial inflammatory phase of bleomycin-induced PF in a mouse model and to verify whether the selected reference genes could be applied to an in-vitro model of BLM-treated primary murine lung fibroblasts...

Neuroblastoma is the most common extracranial solid tumor in children and accounts for 8% to 10% of all childhood cancers. The spread of metastases is both lymphatic and hematogenous. Hematogenous route occurs most commonly in bone marrow and cortical bone; pancreatic metastases are very rare, and there are few reports about this topic in medical literature. We report the case of a 14-year-old boy who suffers a third relapse of neuroblastoma: in this patient I-MIBG confirms that lesions detected by CT were due to a relapse in pancreatic tissue and influenced subsequent therapeutic management...

This paper is concerned with the optimal fusion estimation problem in networked stochastic systems with bounded random delays and packet dropouts, which unavoidably occur during the data transmission in the network. The measured outputs from each sensor are perturbed by random parameter matrices and white additive noises, which are cross-correlated between the different sensors. Least-squares fusion linear estimators including filter, predictor and fixed-point smoother, as well as the corresponding estimation error covariance matrices are designed via the innovation analysis approach...

BACKGROUND: Current guidelines suggest treating blood pressure above 180/105 mm Hg during the first 24 hours in patients with acute ischemic stroke undergoing any form of recanalization therapy. Currently, no studies exist to guide blood pressure management in patients with stroke treated specifically with mechanical thrombectomy. We aimed to determine the association between blood pressure parameters within the first 24 hours after mechanical thrombectomy and patient outcomes. METHODS AND RESULTS: We retrospectively studied a consecutive sample of adult patients who underwent mechanical thrombectomy for acute ischemic stroke of the anterior cerebral circulation at 3 institutions from March 2015 to October 2016...

The activity and efficacy of Aurora inhibitors have been reported in a wide range of cancer types.   The most prominent Aurora inhibitor is Alisertib, an investigational Aurora inhibitor that has been the subject of more than 30 clinical trials.   Alisertib has inhibitory activity against both Aurora A and B, although it is considered to be primarily an Aurora A inhibitor in vivo.  Here we show that Alisertib inhibits both Aurora A and B in vivo in preclinical models of HPV-driven cervical cancer, and that it is the inhibition of Aurora A and B that provide the selectivity and efficacy of this drug in vivo in this disease setting...

Nanoparticles possessing functional groups that can be readily conjugated (e.g. through click chemistry) are important precursors for the preparation of customized nanohybrid products. Such nanoparticles, if they are stable against agglomeration, are easily dispersible and have well-defined surface chemistry and size. As click-ready reagents, they can be stored until their time of use and then simply dispersed and reacted with an appropriate substrate. Gold nanoparticles (AuNPs) are excellent candidates for this purpose and some clickable gold nanoparticles have been developed; however, AuNPs for use in aqueous systems are often prepared through difficult multistep processes and/or can be poorly dispersible in water...

An unconventional strategy is proposed that takes advantage of localized high-deformation areas, referred to as folded wrinkles, to produce microstructured elastic surfaces with precisely controlled pattern dimensions and chemical distribution. For that purpose, elastic PDMS substrates were pre-stretched to a different extent and oxidized in particular areas using a mask. When the stretching was removed and the PDMS substrate exhibited out-of-plane deformations that largely depend on the applied pre-stretching...

To identify barriers to maintaining and applying capabilities of US high-level isolation units (HLIUs) used during the Ebola virus disease outbreak, during 2016 we surveyed HLIUs. HLIUs identified sustainability challenges and reported the highly infectious diseases they would treat. HLIUs expended substantial resources in development but must strategize models of sustainability to maintain readiness.

The oligosaccharyl transferase (OST) complex, localized in the endoplasmic reticulum (ER) of eukaryotic cells, is responsible for the N-linked glycosylation of numerous protein substrates. The membrane protein STT3 is a highly conserved part of the OST, and likely contains the active site of the complex. However, understanding the catalytic determinants of this system has been challenging, in part because of a discrepancy in the structural topology of the bacterial vs eukaryotic proteins and incomplete information about the mechanism of membrane integration...
