Thermosensitive Chitosan hydrogels which can be injected into defects with minimally invasive approach were prepared. Also starch micro/nano particles were synthesized via water-in-oil (W/O) miniemulsion technique. The starch particles were incorporated into the chitosan hydrogel to prepare injectable thermosensitive hydrogel composites. Tube inverting method, compression tests, swelling studies, XRD, SEM, OM, DLS, UV-vis spectroscopy were used for investigations. Results revealed that increasing crosslinker and surfactant contents and stirring rate leads to particle size reduction...

BACKGROUND: In April, 2004, chikungunya virus (CHIKV) re-emerged in Kenya and eventually spread to the islands in the Indian Ocean basin, South-East Asia, and the Americas. The virus, which is often associated with high levels of viremia in humans, is mostly transmitted by the urban vector, Aedes aegypti. The expansion of CHIKV presents a public health challenge both locally and internationally. In this study, we investigated the ability of Ae. aegypti mosquitoes from three distinct cities in Kenya; Mombasa (outbreak prone), Kisumu, and Nairobi (no documented outbreak) to transmit CHIKV...

Tube feeding (TF) is the most common form of nutrition support. In recent years, TF administration has increased among patient populations within and outside hospital settings, in part due to greater insurance coverage, reduced use of parenteral nutrition, and improved formularies suitable for sole source nutrition. With increasing life expectancy and improved access to TFs, the number of adults dependent on enteral nutrition is expected to grow. However, enteral TF intolerance (ETFI) is the most common complication of TFs, typically presenting with at least 1 adverse gastrointestinal event, including nausea, diarrhea, and constipation...

We report a novel self-rolling, conductive, and biocompatible multiwall carbon nanotube (MWCNT)-dopamine-polyethylene glycol (PEG) hydrogel film. The gel can self-fold into a thin tube when it is transferred from a glass slide to an aqueous environment, regardless of the concentrations of the MWCNT. The film presents a highly organized pattern, which results from the self-assembly of hydrophilic dopamine and hydrophobic carbon nanotubes. By exploring the biomedical potential, we found that MWCNT-included rolled film is nontoxic and can promote cell growth...

Kyoung Ha Cha, Mark E Meyerhoff
The compatibility of nitric oxide (NO) release coatings with implantable enzymatic glucose sensors based on osmium (III/II) mediated electrochemical detection is examined for the first time. NO-releasing osmium-mediated glucose sensors are prepared using a S-nitrosothiol impregnated outer tubing and are tested in vitro in both phosphate buffer (pH 7.4) and within whole porcine blood. It is demonstrated that after 3 days of continuous NO release at or above physiological levels, there are no negative effects on the osmium mediated elec-trochemical currents...

Transitionmetal oxides nanoparticles capsuled in amorphous carbon nanotubes (ACNTs) are attractive anode materials of lithium ion batteries (LIBs). Here we firstly designed a fast and universal method with a hydromechanics conception which is called Marangoni flow to fabricating transition bimetal oxides (TBOs) in ACNTs composite with a better electrochemistry performance. Maragoni flows can produce a liquid column with several centimeters high in a tube with one side immersion in the liquid. The key point to induce a Marangoni flow is to make a gradient of the surface tension between the surface and the inside of the solution...

Uterine perforation is an uncommon yet serious complication of surgical management of first and second trimester termination of pregnancies. The rate of uterine perforation is under reported, as patients are usually asymptomatic. Although uncommon, uterine perforation can cause life-threatening complications for some patients. This case report discusses a second trimester surgical termination resulting in uterine perforation and haemorrhage secondary to an avulsion of the infundibulopelvic ligament and prolapse of the left fallopian tube and ovary into the uterine cavity...

Negative effort dependence (NED), decreased airflow despite increased driving pressure, has been proposed as a specific obstructive sleep apnea (OSA) phenotypic characteristic. We examined conditions under which NED occurs in a collapsible tube, chamber enclosed, pharyngeal airway bench model, focusing on relationships with surrounding pressure levels and longitudinal strain. Using a vacuum source, graded airflows (V ̇, 0-5 L/s) were generated through a thin walled latex tube enclosed within a rigid, cylindrical chamber, sealed with initial chamber pressures (Pci) of 0-5 cmH2O (separate runs), or open to atmosphere...

Contractile injection systems mediate bacterial cell-cell interactions by a bacteriophage tail-like structure. In contrast to extracellular systems, the type 6 secretion system (T6SS) is defined by intracellular localization and attachment to the cytoplasmic membrane. Here we used cryo-focused ion beam milling, electron cryotomography, and functional assays to study a T6SS in Amoebophilus asiaticus The in situ architecture revealed three modules, including a contractile sheath-tube, a baseplate, and an anchor...

Versatile, simple and efficient sample preparation is desirable for point-of-care testing of emerging diseases such as zoonoses, but current sample preparation assays are insensitive, labour-intensive and time-consuming and require multiple instruments. We developed a single-tube sample preparation approach involving direct pathogen enrichment and extraction from human specimens using diatomaceous earth (DE). Amine-modified DE was used to directly enrich a zoonotic pathogen, Brucella, in a large sample volume...
