#1
P Gailloud, L Gregg, M S Pearl, D San Millan
Thoracic vertebral arteries are anastomotic chains similar to cervical vertebral arteries but found at the thoracic level. Descending thoracic vertebral arteries originate from the pretransverse segment of the cervical vertebral artery and curve caudally to pass into the last transverse foramen or the first costotransverse space. Ascending thoracic vertebral arteries originate from the aorta, pass through at least 1 costotransverse space, and continue cranially as the cervical vertebral artery. This report describes the angiographic anatomy and clinical significance of 9 cases of descending and 2 cases of ascending thoracic vertebral arteries...

BACKGROUND: Antibody-mediated rejection is the main cause of deterioration of kidney transplants and frequently is detected only by means of protocol biopsies. The aim of this study was to relate the presence of albuminuria throughout the 1st year to the histologic findings detected by 1-year protocol biopsies in kidney graft recipients. METHODS: Retrospective observational study of 86 protocol biopsies 1 year after transplantation. Albuminuria was measured at 3, 6, 9, and 12 months in urine samples and expressed as albumin/creatinine (mg/g)...

It is established that hematopoietic stem cells (HSC) in the hypoxic bone marrow have adapted their metabolism to oxygen-limiting conditions. This adaptation includes suppression of mitochondrial activity, induction of anerobic glycolysis, and activation of hypoxia-inducible transcription factor 1α (Hif1α)-dependent gene expression. During progression of hematopoiesis, a metabolic switch towards mitochondrial oxidative phosphorylation is observed, making this organelle essential for determining cell fate choice in bone marrow...

The expansion of CAG repeats (≥36 CAG) in the HTT gene is the only known genetic cause of Huntington's disease (HD) and the main determinant of the course of the disease. The length of the expanded CAG repeats correlates inversely with the age of onset (AOO) but does not completely determine it. We investigated the role of the melanocortin 1 receptor (MC1R) gene as a modifier factor of AOO in 600 HD patients from Spain. We sequenced the entire region of the MC1R gene and analyzed all the nonsynonymous MC1R genetic variants with a minor allele frequency of at least 0...

Ongoing climate change is driving dramatic range shifts in diverse taxa worldwide, and species responses to global change are likely to be determined largely by population responses at geographical range margins. Here we investigate the metabolic and reproductive plasticity in response to water temperature and salinity variation of two populations of the eurythermic saline water bug Sigara selecta: one population located close to the northern edge of its distribution, in a relatively cold, thermally stable region (SE England - 'marginal'), and one close to the range centre, in a warmer and more thermally variable Mediterranean climate (SE Spain - 'core')...

The Mediterranean fruit fly (medfly), Ceratitis capitata is a highly polyphagous pest, which infests multiple species of fruits and vegetables worldwide. In addition to the traditional control with chemical insecticides, sterile insect technique (SIT) has been implemented in integrated programs worldwide, and has become an essential measure for the control of this pest. A key issue for SIT is to release sterile males that are sufficiently competitive with males from the wild population. Using sequence information available in public databases, three novel picornaviruses infecting medflies were discovered and named as C...

We maintain a stable perception of the visual world despite continuous movements of our eyes, head and body. Perception of upright is a key aspect of such orientation constancy. Here we investigated whether changes in upright perception during sustained head tilt were related to simultaneous changes in torsional position of the eyes. We used a subjective visual vertical (SVV) task, modified to track changes in upright perception over time, and a custom video method to measure ocular torsion simultaneously. We tested 12 subjects in upright position, during prolonged (~15 min) lateral head tilts of 20 degrees, and also after the head returned to upright position...

BACKGROUND: Guidelines recommend that patients with hepatitis C virus (HCV)-related liver disease be treated for HCV before liver transplant (LT) to eliminate the virus prior to surgery. However, the unpredictability of donor organ availability may limit treatment duration. Interruption of HCV treatment with resumption post-LT is one potential solution which has not been investigated widely. METHODS: Patients from 5 clinical centres included in the large, national, noninterventional Hepa-C registry who started treatment with direct-acting antiviral agents (DAAs) while awaiting LT were identified retrospectively and followed up prospectively...

Chromosomal abnormalities are one of the main causes of genetic infertility in horses. Currently, their detection rate is rising due to the use of new diagnostic tools employing molecular markers linked to the sex chromosome pair. Despite genetic similarities, there are no previous reports of sterility associated with chromosomal abnormalities in the domestic donkey (Equus asinus). Hereby, we determined the presence of a chromosomal mosaicism in a female donkey with reproductive problems using molecular methodologies developed for horses...

PURPOSE: Antinuclear autoantibodies (ANA) targeting the dense fine speckled antigen DFS70, also known as lens epithelium-derived growth factor p75 (LEDGF/p75), are attracting attention due to their low frequency in systemic rheumatic diseases but increased frequency in clinical laboratory referrals and healthy individuals (HI). These ANA specifically recognize the stress protein DFS70/LEDGFp75, implicated in cancer, HIV-AIDS, and inflammation. While their frequency has been investigated in various ethnic populations, there is little information on their frequency among Hispanics/Latinos...

ColE1 plasmids are small mobilizable replicons that play an important role in the spread of antibiotic resistance in Pasteurellaceae. In this study we describe how a natural single nucleotide polymorphism (SNP) near the origin of replication of the ColE1-type plasmid pB1000 found in a Pasteurella multocida clinical isolate, generates two independent plasmid variants able to coexist in the same cell simultaneously. Using Haemophilus influenzae Rd strain as a model system, we combined antibiotic susceptibility tests, quantitative PCRs, competition assays and experimental evolution to characterize the consequences of the coexistence of the pB1000 plasmid variants...

BACKGROUND: The outcome for patients with Multiple Myeloma (MM) is highly variable, therefore, the existence of robust and easy to determine prognostic markers is extremely important for an efficient management of these patients. Presently, there is a debate about the role of the serum free light chains (sFLC) in the prognosis of MM patients both at diagnosis and after treatment. The aim of this study is to evaluate in a cohort of newly diagnosed MM patients from the Southern area of Spain, the prognostic value of sFLC both at baseline and after treatment...

Quantitative glycomics represents an actively expanding research field ranging from the discovery of disease associated glycan alterations to the quantitative characterization of N-glycans on therapeutic proteins. Commonly used analytical platforms for comparative relative quantitation of complex glycan samples include MALDI-ToF-MS or chromatographic glycan profiling with subsequent data alignment and statistical evaluation. Limitations of such approaches include run-to-run technical variation and the potential introduction of subjectivity during data processing...

Fixational eye movements (FEM), including microsaccades, drift, and tremor, shift our eye position during ocular fixation, producing retinal motion that is thought to help visibility by counteracting neural adaptation to unchanging stimulation. Yet, how each FEM type influences this process is still debated. Recent studies found little to no relationship between microsaccades and visual perception of spatial frequencies (SF), and concluded that any effects microsaccades may have on vision do not extend to the SF domain...

PCSK9 is a protease, synthesized mainly in the liver, which promotes the hepatic degradation of the LDL receptor and consequently decreases LDL receptor density and clearance of LDL particles. Statins inhibit HMG-CoA-reductase activity, an enzyme that catalyses an important step in hepatic cholesterol biosynthesis. The decrease of the hepatic intracellular cholesterol pool produced by these drugs upregulates the activity of the SREBP2 transcription factor, which subsequently stimulates the expression of the LDL receptor gene, an effect that is followed by an increase in the serum concentration of PCSK9...

INTRODUCTION: The incidence of inflammatory bowel disease (IBD) is increasing in Spain but there is little information on the availability of multidisciplinary care. This study aims to assess surgeon's opinions on the current situation of surgery for IBD in Spain. METHODS: An electronic closed survey was sent to members of the Spanish Association of Surgeons (AEC) from January to March 2015. This was a 52-item anonymised questionnaire with questions about how the treatment of IBD patients is organized in each centre, the existence of specific units, the management strategy in IBD patients, and the opinion of colorectal, general and trainee surgeons about the surgical treatment of IBD in their centre and in Spain...
