Fu-Sheng Deng, Ching-Hsuan Lin
Cellular signaling pathways involved in cell growth and differentiation mediated by mitogen-activated protein kinase (MAPK) cascades have been well characterized in fungi. However, the mechanisms of signaling crosstalk between MAPKs to ensure signaling specificity are largely unknown. Previous work showed that activation of the Candida albicans Cek1 MAPK pathway resulted in opaque cell formation and filamentation, which mirrored the phenotypes to hog1Δ. Additionally, deleting the HOG1 gene stimulated Cek1p...

Campylobacter concisus is a bacterium that is associated with inflammatory bowel disease (IBD). Immunosuppressive drugs including azathioprine (AZA) and mercaptopurine (MP), and anti-inflammatory drug such as 5-aminosalicylic acid (5-ASA) are commonly used to treat patients with IBD. This study aimed to examine the effects of AZA, MP, and 5-ASA on the growth of IBD-associated bacterial species and to identify bacterial enzymes involved in immunosuppressive drug metabolism. A total of 15 bacterial strains of five species including 11 C...

PURPOSE: The loss of potency of protein therapeutics can be linked to the oxidation of specific amino acid residues leading to a great variety of oxidative modifications. The comprehensive identification of these oxidative modifications requires high-resolution mass spectrometry analysis, which requires time and expensive resources. Here, we propose a fluorogenic derivatization method of oxidized Tyr and Phe yielding benzoxazole derivatives, as an orthogonal technique for the rapid screening of protein oxidation...

BACKGROUND: Avulsion fractures of the pelvic apophyses typically occur in adolescent athletes due to a sudden strong muscle contraction while growth plates are still open. The main goals of this systematic review with meta-analysis were to summarize the evidence on clinical outcome and determine the rate of return to sports after conservative versus operative treatment of avulsion fractures of the pelvis. METHODS: A systematic search of the Ovid database was performed in December 2016 to identify all published articles reporting outcome and return to preinjury sport-level after conservative or operative treatment of avulsion fractures of the pelvis in adolescent patients...

Pseudomonas aeruginosa is an efficient biofilm-dwelling microbial pathogen, associated with nosocomial infections. These biofilm-associated infections are resistant to antibiotics and immune defenses, therefore pose major problem against their treatment. This scenario demands alternative therapeutic regimens, and bacteriophage therapy is one among potential strategies for clinical management of multiple drug resistance. In this investigation, the efficacy of a bacteriophage, JHP, is evaluated to eradicate P...

We report on the detection of the time-dependent B-field amplitude and topology in a laser-driven solenoid. The B-field inferred from both proton deflectometry and Faraday rotation ramps up linearly in time reaching 210 ± 35 T at the end of a 0.75-ns laser drive with 1 TW at 351 nm. A lumped-element circuit model agrees well with the linear rise and suggests that the blow-off plasma screens the field between the plates leading to an increased plate capacitance that converts the laser-generated hot-electron current into a voltage source that drives current through the solenoid...

Fractures of the upper limbs are frequent and often need operative treatment in addition to a well-indicated conservative management. This depends on the maturity of the nearest growth plate and the local remodeling potential, which is dependent on age. Following conventional x‑ray imaging an individual prognostic growth analysis leads to the therapeutic decision. Around the elbow and the shaft of the forearm, criteria are stricter than near the shoulder or wrist. Gilchrist or Desault bandages as well as braces are adequate for most subcapital and humeral shaft fractures...

Xiao Li Yang, Li Guo Qi, Feng Juan Lin, Zhou Luo Ou
Considerable attention has recently been paid to the application of chemokines to cancer immunotherapy due to their complex role in cell proliferation, invasion, metastasis, and tumorigenesis, which extends beyond the regulation of lymphocyte migration during immune responses. The expression and the function of the chemokine receptor XCR1 on breast cancer have remained elusive to date. In this study, the expressions of XCR1 mRNA were tested by quantitative real-time polymerase chain reaction in one breast epithelial cell line (MCF-10A) and nine breast cancer cell lines (MDA-MB-231, 231HM, 231BO, MDA-MB-468, MCF-7, T47D, Bcap-37, ZR-75-30, and SK-BR-3)...

The objective of this study was to determine whether common bacterial catfish pathogens could attach and colonize surfaces commonly found in aquaculture facilities. In addition, we evaluated the role of calcium in biofilm formation. Attachment to polystyrene plates was used to quantify biofilm formation by five bacterial pathogens (i.e., Flavobacterium columnare, Aeromonas hydrophila, Edwardsiella ictaluri, E. tarda, and E. piscicida). Flavobacterium columnare and A. hydrophila formed thick biofilms that were enhanced by calcium supplementation...

Experiments were conducted on an aqueous growth medium containing cultures of Escherichia coli (E. coli) XL1-Blue, to investigate, in a single experiment, the effect of two types of dynamic mechanical loading on cellular integrity. A bespoke shock tube was used to subject separate portions of a planktonic bacterial culture to two different loading sequences: (i) shock compression followed by cavitation, and (ii) shock compression followed by spray. The apparatus allows the generation of an adjustable loading shock wave of magnitude up to 300 MPa in a sterile laboratory environment...

A comparison between plate counting (PC) and dynamic light scattering (DLS) is reported. PC is the standard technique to determine bacterial population as a function of time; however, this method has drawbacks, such as the cumbersome preparation and handling of samples, as well as the long time required to obtain results. Alternative methods based on optical density are faster, but do not distinguish viable from non-viable cells. These inconveniences are overcome by using DLS. Two different bacteria strains were considered: Escherichia coli and Staphylococcus aureus...

Maggot debridement therapy (MDT) refers to the use of blowfly larvae to clean or debride an infected wound. Most commonly, larvae of Lucilia sericata (Meigen) (Diptera: Calliphoridae) are used, and are sterilized prior to use to ensure no further bacterial infections are introduced during treatment. Current methods sterilize eggs from laboratory-reared blowfly colonies, after which sterile early second instar maggots can be provided to hospitals for use in treatment. Maggots not required for treatment are used for colony regeneration, in which sterility is not maintained...
