Reports on the effects of length of dry period (DP) on udder health of cows that were not treated with dry cow antibiotics are scarce. Additionally, the effects of a reduced dietary energy level for cows with a 0-d DP on udder health have not yet been studied. The aims of this study were (1) to compare effects of a 0-d or 30-d DP without use of dry cow antibiotics on udder health across the DP and subsequent lactation in dairy cows fed different dietary energy levels and (2) to evaluate associations between udder health and metabolic status of dairy cows...

A new route to lactide, key building block of the bioplastic polylactic acid, is proposed via a continuous catalytic gas-phase transesterification of renewable alkyl lactates in a scalable fixed-bed setup. Supported TiO2/SiO2 catalysts are highly selective to lactide, with only minimal lactide racemization. The solvent-free process allows for easy product separation and recycling of unconverted alkyl lactates and recyclable lactyl intermediates. The catalytic activity of TiO2/SiO2 catalysts was strongly correlated to their optical properties by DR UV-VIS spectroscopy...

Neurocysticercosis is a parasitic infection of the central nervous system caused by the larval stage of Taenia solium. Although this zoonotic infection is one of the major public health problems in some developing countries, it is extremely rare in Turkey. In this article, we present the case of a pediatric patient with neurocysticercosis who was misdiagnosed with brain abscess because of focal seizures in another hospital.

In pursuit of more sustainable and competitive biorefineries, the effective valorisation of lignin is key. An alluring opportunity is the exploitation of lignin as a resource for chemicals. Three technological biorefinery aspects will determine the realisation of a successful lignin-to-chemicals valorisation chain, namely (i) lignocellulose fractionation, (ii) lignin depolymerisation, and (iii) upgrading towards targeted chemicals. This review provides a summary and perspective of the extensive research that has been devoted to each of these three interconnected biorefinery aspects, ranging from industrially well-established techniques to the latest cutting edge innovations...

To investigate alleviative effect of selenium (Se) on lead (Pb)-induced apoptosis in chicken nervous tissues, 7-day-old chickens were randomly divided into four groups. The control group was fed a standard diet and drinking water. In the Pb and Se/Pb groups, (CH3OO)2Pb was dissolved in drinking water. In the Se and Se/Pb groups, Na2SeO3 was put into the standard diet. Embryonic neurocytes were divided into the control, Se (containing Na2SeO3), Pb (containing (CH3COO)2Pb), and Se/Pb (containing Na2SeO3 and (CH3COO)2Pb) groups...

The lab-on-a-chip (LOC) field has witnessed an excess of new technology concepts, especially for the point-of-care (POC) applications. However, only few concepts reached the POC market often because of challenging integration with pumping and detection systems as well as with complex biological assays. Recently, a new technology termed SIMPLE was introduced as a promising POC platform due to its features of being self-powered, autonomous in liquid manipulations, cost-effective and amenable to mass production...

In 2012 a seismic survey campaign involving four vessels was conducted in Baffin Bay, West Greenland. Long-distance (150 km) pre-survey acoustic modeling was performed in accordance with regulatory requirements. Four acoustic recorders, three with hydrophones at 100, 200, and 400 m depths, measured ambient and anthropogenic sound during the survey. Additional recordings without the surveys were made from September 2013 to September 2014. The results show that (1) the soundscape of Baffin Bay is typical for open ocean environments and Melville Bay's soundscape is dominated by glacial ice noise; (2) there are distinct multipath arrivals of seismic pulses 40 km from the array; (3) seismic sound levels vary little as a function of depth; (4) high fidelity pre-survey acoustic propagation modeling produced reliable results; (5) the daily SEL did not exceed regulatory thresholds and were different using Southall, Bowles, Ellison, Finneran, Gentry, Greene, Kastak, Ketten, Miller, Nachtigall, Richardson, Thomas, and Tyack [(2007) Aquat...

BACKGROUND: Spinal epidural lipomatosis (SEL) is a rare pathologic growth of histologically normal unencapsulated adipose tissue in the epidural space. Although rare, SEL can compress the spinal cord or nerve roots causing myelopathy or radiculopathy. While SEL has been associated with long-term exposure to endogenous or exogenous steroids and obesity, idiopathic forms of SEL are much rarer. CASE REPORT: In this report, we present the first case of SEL isolated to the cervical region compressing the spinal cord in a healthy, non-obese, preadolescent patient...

Functionally redundant genes present a puzzle as to their evolutionary preservation, and offer an interesting opportunity for molecular specialization. In Caenorhabditis elegans, either one of two presenilin genes (sel-12 or hop-1) facilitate Notch activation, providing the catalytic subunit for the gamma secretase proteolytic enzyme complex.  For all known Notch signaling events, sel-12 can mediate Notch activation, so the conservation of hop-1 remains a mystery. Here, we uncover a novel "late-onset" germline Notch phenotype in which HOP-1-deficient worms fail to maintain proliferating germline stem cells during adulthood...
