The trophic transfer of cyclic methylsiloxanes (cVMS) in aquatic ecosystems is an important criterion for assessing bioaccumulation and ecological risk. Bioaccumulation and trophic transfer of cVMS, specifically octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclohexasiloxane (D6), were evaluated for the marine food webs of the Inner and Outer Oslofjord, Norway. The sampled food webs included zooplankton, benthic macroinvertebrates, shellfish, and finfish species. Zooplankton, benthic macroinvertebrates, and shellfish occupied the lowest trophic levels (TL ≈2 to 3); northern shrimp (Pandalus borealis) and Atlantic herring (Clupea harengus) occupied the middle trophic levels (TL ≈3 to 4), and Atlantic cod (Gadus morhua) occupied the highest tropic level (TL>4...

There is an ever-increasing need to develop dental implants with ideal characteristics to achieve specific and desired biological response in the scope of improve the healing process post-implantation. Following that premise, enhancing and optimizing titanium implants through superficial treatments, like silica sol-gel hybrid coatings, are regarded as a route of future research in this area. These coatings change the physicochemical properties of the implant, ultimately affecting its biological characteristics...

Liver tissue engineering has emerged as a promising approach in organ transplantation, but has been hampered by the lack of a reliable and readily available cell source. Induced pluripotent cells (hiPSC) have been highlighted a desirable source, due to their differentiation potential, ability to self-renew and the possibility of making patient specific cells. We developed a decellularization protocol that efficiently removes cellular material, while retaining extracellular matrix components. Subsequently, hiPSC were differentiated on the decellularized human liver matrix (hDLM) scaffolds using an established hepatic differentiation protocol...

Oat crown rust is one of the most damaging diseases of oat. We identified a new source of resistance and developed KASP and TaqMan markers for selection in breeding programs. A new highly effective resistance to oat crown rust (Puccinia coronata f. sp. avenae) was identified in the diploid oat Avena strigosa PI 258731 and introgressed into hexaploid cultivated oat. Young plants with this resistance show moderate susceptibility, whereas older plant tissues and adult plants are resistant with no virulent isolates encountered in over 8 years of testing...

Interaction between tumour and host triggers a systemic inflammatory response. This situation has been associated to cancer progression. Several peripheral blood inflammatory scores have been recently developed, as PLR. Data about the relationship between these scores and cancer prognosis are contradictory. Therefore, the aim of our work is to evaluate the capability of PLR to predict long-term outcomes (OS and RFS) in patients who underwent curative surgery for colon cancer. A retrospective study was designed with patients who underwent curative surgery for colon cancer between September 2008 and January 2012 at Rio Hortega University Hospital, Valladolid (Spain)...

Monitoring of forest resources through national forest inventory programmes is carried out in many countries. The expected climate changes will affect trees and forests and might cause an expansion of trees into presently treeless areas, such as above the current alpine tree line. It is therefore a need to develop methods that enable the inclusion of also these areas into monitoring programmes. Airborne laser scanning (ALS) is an established tool in operational forest inventories, and could be a viable option for monitoring tasks...

Saving the outer ear in burn injuries is a challenging task for the treating surgeon that should not be underestimated. Burns which are initially evaluated as superficial, particularly in this region, often have a tendency to undergo progressive tissue destruction whereby conservative treatment is often no longer sufficient to preserve the skin of the auricle with the underlying cartilage. Various possibilities for saving the ear and for ear reconstruction are described, but in the case of severely burned patients it is often necessary to carry out a quick and relatively simple treatment...

Most people with mantle cell lymphoma (MCL) present with diffuse adenopathy and benefit from early initiation of rituximab and high-dose cytarabine- or bendamustine-based therapies. Some patients, however, present with primarily nonnodal disease that can follow either an indolent or a rapidly progressive, treatment-resistant clinical course. Rarely, patients present with explosive disease that can be challenging to manage and often involves the central nervous system. New agents with improved therapeutic indices facilitate treatment while maintaining quality of life, but also present new complications at the time of treatment failure...

Centrosomes are microtubule-nucleating organelles that facilitate chromosome segregation and cell division in metazoans. Centrosomes comprise centrioles that organize a micron-scale mass of protein called pericentriolar material (PCM) from which microtubules nucleate. During each cell cycle, PCM accumulates around centrioles through phosphorylation-mediated assembly of PCM scaffold proteins. During mitotic exit, PCM swiftly disassembles by an unknown mechanism. Here, we used Caenorhabditis elegans embryos to determine the mechanism and importance of PCM disassembly in dividing cells...

The role of extracellular vesicles in cancer biology has emerged as a focus of the study of great importance and has been shown to directly influence tumour development in several cancers including brain tumours, such as gliomas. Gliomas are the most aggressive brain tumours, and in the last time, a considerable effort has been made to understand their biology. Studies focus in the signalling pathways involved in the processes of angiogenesis, viability, drug resistance and immune response evasion, as well as gliomas ability to infiltrate healthy tissue, a phenomenon regulated by the migratory and invasive capacity of the cells within a tumour...
