BACKGROUND: The interest in detailed anatomy of the sella and parasellar regions has resurged recently due to the wide clinical applications of the expanded endoscopic approaches to the skull base. The middle clinoid process (MCP) is a bony structure that can affect wide endoscopic exposure of the sella and parasellar region. OBJECTIVE: To study and analyze the anatomic variations of the MCP in the general population using computed tomography scans. METHODS: A total of 150 maxillofacial computed tomography scans were reviewed to characterize the MCP...

Over the last decade it has become increasingly clear that Zetaproteobacteria are widespread in hydrothermal systems and that they contribute to the biogeochemical cycling of iron in these environments. However, how chemical factors control the distribution of Zetaproteobacteria and their co-occurring taxa remains elusive. Here we analysed iron mats from the Troll Wall Vent Field (TWVF) located at the Arctic Mid-Ocean Ridge (AMOR) in the Norwegian-Greenland Sea. The samples were taken at increasing distances from high-temperature venting chimneys towards areas with ultraslow low-temperature venting, encompassing a large variety in geochemical settings...

Between-female variation in reproductive output provides a strong measure of individual fitness and a quantifiable measure of the health of a population which may be highly informative to management. In the present study, we examined reproductive traits in female bottlenose dolphins from the east coast of Scotland using longitudinal sightings data collected over twenty years. From a total of 102 females identified between 1997 and 2016, 74 mothers produced a collective total of 193 calves. Females gave birth from 6 to 13 years of age with a mean age of 8...

MBI9915 is an introgression cotton line with excellent fiber quality. It was obtained by advanced backcrossing and continuous inbreeding from an interspecific cross between the upland cotton (Gossypium hirsutum) cultivar CCRI36 as the recurrent parent and the sea island cotton (G. barbadense) cultivar Hai1, as the donor parent. To study the genetic effects of the introgressed chromosome segments in G. hirsutum, an F2 secondary segregating population of 1537 individuals was created by crossing MBI9915 and CCRI36, and an F2:3 population was created by randomly selecting 347 individuals from the F2 generation...

The all-female Caucasian rock lizard Darevskia rostombekowi and other unisexual species of this genus reproduce normally via true parthenogenesis. Typically, diploid parthenogenetic reptiles exhibit some amount of clonal diversity. However, allozyme data from D. rostombekowi have suggested that this species consists of a single clone. Herein, we test this hypothesis by evaluating variation at three variable microsatellite loci for 42 specimens of D. rostombekowi from four populations in Armenia. Analyses based on single nucleotide polymorphisms of each locus reveal five genotypes or presumptive clones in this species...

RATIONALE: With refinements in the operative technique, laparoscopic surgery has become the standard practice for liver resection. In the field of living donor liver transplantation, a few centers adopted laparoscopic surgery as an alternative to conventional open donor hepatectomy, and the application of pure laparoscopic donor right hepatectomy has been limited to the donors with simple, favorable biliary anatomy. PATIENT CONCERNS: The candidate donor was a 19-year-old woman with type 3a bile duct variation...

BACKGROUND: The valid estimation of the usual dietary intake remains a challenge till date. We applied the method suggested by the National Cancer Institute (NCI) to data from the 2nd Bavarian Food Consumption Survey (BVS II) and compared it to an individual means approach. METHODS: Within the cross-sectional BVS II, 1,050 Bavarian residents aged 13-80 years participated in a personal interview and completed three 24-h dietary recalls by telephone interview. For the 13 main food groups and 23 subgroups the usual intake was calculated by (1) an individual means approach and (2) by the NCI method...

Antibodies that target both group 1 and group 2 influenza A viruses are valuable for therapeutic and vaccine development, but only a few have been reported to date. Here, we describe a new VH1-69 antibody 27F3 that broadly recognizes heterosubtypic hemagglutinins (HAs) from both group 1 and group 2 influenza A viruses. Structural characterization of 27F3 Fab with A/California/04/2009 (H1N1) hemagglutinin illustrates that 27F3 shares the key binding features observed in other VH1-69 antibodies to the HA stem...

Some microbial metabolites can be immunomodulatory, but there is limited understanding of how these contribute to inter-individual variation in response to infection. In a recent study in Science, Steed et al. (2017) show that the bacterial metabolite desaminotyrosine (DAT) increases type I interferon expression, resulting in an improved immune response to influenza infection.

Exosomes are a subset of extracellular vesicles (EVs) that have important roles in intercellular communication. They contain and carry bioactive molecules within their membranes which are delivered to target cells. Reproducible isolation and enrichment of these exosomes will aid in evaluation of cellular communication. We present an approach that involved the pre-processing of plasma, combined with ultracentrifugation (UC) and size exclusion chromatography (SEC) to isolate EVs and subsequently enrich exosomes...
