An appropriate surface chemical property is crucial in tissue engineering scaffolds, which promotes cell attachment and proliferation. A biomimetic composite scaffold with a polydopamine (PDA) coating layer on electrospun poly(lactic acid) (PLA)/cellulose nanofibrils (CNF) composite nanofiber was developed in this study. PLA/CNF composite nanofibers were fabricated and then coated via treatment with a dopamine solution. The PDA coating layer was successfully formed on the surface of the PLA/CNF composite nanofiber by using a simple, environment-friendly, and effective procedure...

Successful reconstruction of the oromandibular defect with the osteoseptocutaneous fibula flap necessitates flawless design and inset, an experience-demanding endeavor. Laterality of the fibula flap has been thought to pose a certain challenge to the reconstruction. To address this concern and guide flap design and inset, the authors propsed using the surgeon's fist with the thumb up to replicate key anatomic land marks of the fibula flap: the peroneal vessels and proximal bone end, the posterior crural septum including the septal vessels, the skin, and the lateral surface of the fibula bone...

Acute suppurative bacterial dacryoadenitis (ASBD) with abscess formation is rarely seen in clinical practice. A retrospective review of medical records in the past 8 years identified two unilateral cases in children, one developed presumably after methicillin-sensitive Staphylococcus aureus (MSSA) conjunctivitis and the other due to community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infection. Computerized tomography scans showed globe indentation by the enlarged lacrimal glands with rim-enhancing lesions...

Christopher A Chung
In 2010, the article Location and Analysis of Emergency Management Point of Distributions (PODs) for Hurricane Ike was published in the Journal of Emergency Management. Using a program titled point of distribution locator (POD Locator 1.0), the article reported a 46 percent improvement in positioning PODs over the locations selected by emergency managers during Hurricane Ike in 2008. While the program could produce more effective POD locations for a given situation, a major weakness of the program was the difficulty with which population and location data were manually entered into the program for subsequent analysis...

A bacterial strain designated LYH-12T was isolated from a freshwater fish culture pond in Taiwan, ROC and characterized by taking a polyphasic taxonomy approach. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain LYH-12T belonged to the genus Hymenobacter and was most closely related to Hymenobacter xinjiangensis X2-1gT and Hymenobacter rigui WPCB131T with a sequence similarity of 96.6 % and less than 96.5 % with other members of the genus. Cells of strain LYH-12T were Gram-stain-negative, aerobic, non-motile rods that were covered by large capsules and formed light pink-coloured colonies...

OBJECTIVE: To evaluate the feasibility of predicting labor outcome using serial transperineal ultrasound (TPU) in the early active phase of labor. METHODS: This is a single center prospective observational study in a tertiary obstetrics unit in Hong Kong. Nulliparous women carrying singleton pregnancy at the onset of active phase of labor were recruited. Serial 3D volumes by TPU were acquired and then repeated after 1 and 2 hours, which were subsequently analyzed for fetal head symphyseal distance (HSD), angle of progression (AoP) and fetal head progression distance (PD)...

BACKGROUND: Mammography detects calcium deposits sensitively, but the specificity for differentiating malignancy from benign calcifications is low. Thus, we investigated whether adjunctive breast-specific gamma imaging (BSGI) has incremental value for detecting cancer in women with suspicious calcifications detected by mammography, and compared BSGI with adjunctive ultrasonography (US). METHODS: The medical records of women without a personal history of breast cancer who underwent mammography for breast evaluation from 2009 to 2014 were reviewed retrospectively...

Examining the hematogenous compartment for evidence of metastasis has increased significantly within the oncology research community in recent years, due to the development of technologies aimed at the enrichment of circulating tumor cells (CTCs), the subpopulation of primary tumor cells that gain access to the circulatory system and are responsible for colonization at distant sites. In contrast to other technologies, filtration-based CTC enrichment, which exploits differences in size between larger tumor cells and surrounding smaller, non-tumor blood cells, has the potential to improve CTC characterization through isolation of tumor cell populations with greater molecular heterogeneity...

The accurate detection of disease-related biomarkers is crucial for the early diagnosis and management of disease in personalized medicine. Here, we present a molecular imaging of human epidermal growth factor receptor (EGFR)-expressing malignant tumors using an EGFR-specific repebody composed of leucine-rich repeat (LRR) modules. The repebody was labeled with either a fluorescent dye or radioisotope, and used for imaging of EGFR-expressing malignant tumors using an optical method and positron emission tomography...

Objectives: Therapy outcomes for newly diagnosed, critically ill lung cancer patients have seldom been evaluated. This study evaluated therapy outcomes for treatment-naïve lung cancer patients in the intensive care unit (ICU). Materials and Methods: Patients were excluded if they had previously received lung cancer treatment, such as systemic chemotherapy, targeted therapy, radiotherapy, or surgical lung resection before ICU admission. The therapeutic strategies for the treatment-naïve patients were determined while they were in the ICU...

To investigate the role of TGF-β and IL-6 in myofibroblasts (MFs) - lung cancer cell interactions, lung cancer cells (Lewis and CTM-167 cell lines) were stimulated by IL-6, MF-conditioned medium (MF-CM) or MFs, with or without TGF-β signaling inhibitor - SB431542 and/or JAK2/STAT3 inhibitor - JSI-124. MFs were stimulated by TGF-β, cancer cell-CM or cancer cells, with or without SB431542 and JSI-124. Cell proliferation, the levels of cytokines, expression of mRNA and protein were determined. Mice bearing xenograft tumors were intraperitoneally treated with SB431542 or JSI-124 and monitored for up to 45 days...

In contrast to their terrestrial call, the offshore call of penguins during their foraging trips has been poorly studied due to the inaccessibility of the foraging site-the open ocean-to researchers. Here, we present the first description of the vocal behaviour of penguins in the open ocean and discuss the function of their vocal communication. We deployed an animal-borne camera on gentoo penguins (Pygoscelis papua) and recorded their foraging behaviour during chick guarding. From the video recordings, we collected 598 offshore calls from 10 individuals in two breeding seasons (2014-2015 and 2015-2016), and we analysed the acoustic characteristics and behavioural contexts of these calls, including diving patterns, group association events, and foraging behaviour...

Outbreaks of multidrug-resistant Gram-negative bacterial infections have been reported worldwide. Colistin, an antibiotic with known nephrotoxicity and neurotoxicity, is now being used to treat multidrug-resistant Gram-negative strains. In this study, we applied an on-spot internal standard addition approach coupled with an ultra high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to quantify colistin A and B from dried blood spots (DBSs). Only 15μL of whole blood was required for each sample...

The green microalga Botryococcus braunii of the B race accumulates various lipophilic compounds containing a 10,11-oxidosqualene epoxide moiety in addition to large amounts of triterpene hydrocarbons. While 2,3-squalene epoxidases have already been isolated and characterized from the alga, the enzyme that catalyzes the 10,11-epoxidation of squalene has remained elusive. In order to obtain a molecular tool to explore a 10,11-squalene epoxidase, cDNA cloning of an NADPH-dependent cytochrome P450 reductase (CPR) that is required by both squalene epoxidases and cytochrome P450 enzymes was carried out...

We present a new thermomechanical method and a platform to measure the phase transition temperature at microscale. A thin film metal sensor on a membrane simultaneously measures both temperature and mechanical strain of the sample during heating and cooling cycles. This thermomechanical principle of operation is described in detail. Physical hydrogel samples are prepared as a disc-shaped gels (200 μm thick and 1 mm diameter) and placed between an on-chip heater and sensor devices. The sol-gel transition temperature of gelatin solution at various concentrations, used as a model physical hydrogel, shows less than 3% deviation from in-depth rheological results...

This study proposes a different angle to social network analysis that evaluates patent value and explores its influencing factors using the network centrality and network position. This study utilizes a logistic regression model to explore the relationships in the LED industry between patent value and network centrality as measured from out-degree centrality, in-degree centrality, in-closeness centrality, and network position, which is measured from effect size. The empirical result shows that out-degree centrality and in-degree centrality have significant positive effects on patent value and that effect size has a significant negative effect on patent value...

During spinal cord development, endogenous progenitors expressing nestin can migrate into the target and differentiate into neurons and other glial cells. Microglial cells can also be derived from nestin progenitor cells, even in the adult brain. Knockdown of Jak kinase 3 (Jak3) signaling can increase neurogenesis with longer neurite outgrowth in cortical progenitor cells. This study investigated the effect of Jak3 signaling on differentiation from nestin progenitor cells using E13.5 spinal progenitor cell cultures...
