The mitogen-activated protein kinase (MAPK) extracellular signal-regulated kinase signaling pathway can be activated through mutations of V-RAF murine sarcoma viral oncogene homolog B1 (BRAF) oncogene, frequently found in melanoma (60%), common nevi (CN) (73-82%), and atypical nevi (AN) (52-80%). MAPK activation has been reported between 0 and 22% in nevi,(More)
Sjögren's syndrome (SS) is a chronic inflammatory autoimmune disease that mainly affects tear and salivary glands, whereby SS-patients frequently complain of eye and mouth dryness. Salivary acinar cells of SS-patients display alterations in their cell polarity; which may affect the correct localization and function of proteins involved in regulated(More)
OBJECTIVE Oral and ocular dryness are frequent and serious symptoms of Sjögren's syndrome (SS) that reflect problems in secretion due to glandular dysfunction. Exocytosis, an important process in the secretory pathway, requires the participation of Rab family GTPases. This study was undertaken to analyze the expression and localization of Rab3D and Rab8A(More)
The antimicrobial susceptibility of 151 clinical Streptococcus suis strains isolated from diseased pigs in Spain was determined by a microdilution method. Isolates were mostly susceptible to beta-lactam antimicrobials, aminoglycosides, enrofloxacin, novobiocin and spectinomycin. More than 87% of the S. suis isolates were resistant to tetracyclines,(More)
Schwann cells produce myelin sheath around peripheral nerve axons. Myelination is critical for rapid propagation of action potentials, as illustrated by the large number of acquired and hereditary peripheral neuropathies, such as diabetic neuropathy or Charcot-Marie-Tooth diseases, that are commonly associated with a process of demyelination. However, the(More)
We present well sampled optical (UBV RI) and infrared (JHK) light curves of the nearby (≈18.0 Mpc) Type Ia supernova SN 2001el, from 11 days before to 142 days after the time of B-band maximum. The data represent one of the best sets of optical and infrared photometry ever obtained for a Type Ia super-nova. Based on synthetic photometry using optical(More)
—This paper presents a wireless interface to control a LEGO NXT robot using voice commands through a computer. To perform speech recognition is used CSLU TOOLKIT with a corpus of Mexican Spanish voice, recognized commands are sent via Bluetooth from computer to robot, programming and motion routines to control the motors are done using Java and LeJOS NXJ.(More)
The patient presented here is a 30-year-old woman who underwent anterior resection for the initial treatment of rectal cancer. A postoperative study showed a single liver metastasis. The patient received adjuvant pelvic radiotherapy with concomitant 5-fluorouracil (5-FU) treatment followed by liver metastasectomy 6 weeks after the completion of radiation(More)
BRAF mutations have recently been detected with a high frequency (66%) in cutaneous melanoma. All those mutations are activating, with a single substitution (T1796A) at codon 599 (V599E) accounting for over 90%. To investigate the stage in which those mutations occur in the currently proposed sequential malignant transformation of melanocytes, 22 benign(More)
Brucella melitensis is a major human and animal pathogen, with a wide host range that includes all domestic ruminant species, although small ruminants are its preferred hosts. Outbreaks in cattle due to B. melitensis have become a worldwide emerging problem particularly difficult to control due to the lack of knowledge on the epidemiology in this host(More)
