16S rDNA-based analysis of dominant bacterial populations associated with early life stages of coho salmon (Oncorhynchus kisutch)
(SPRINGER, 2006-05)In this study, we used a 16S rDNA-based approach to determine bacterial populations associated with coho salmon (Oncorhynchus kisutch) in its early life stages, highlighting dominant bacteria in the gastrointestinal tract ... -
17-beta-Estradiol upregulates COX-2 in the rat oviduct
(ELSEVIER, 2006-09)We investigated the regulation of cyclooxygenase-2 (COX-2) by 17-beta-estradiol (E-2) in the rat oviduct. We observed that COX-2 is expressed mainly in proestrous and estrous stages, periods under estrogenic influence. ... -
2,3-butanedione monoxime affects cystic fibrosis transmembrane conductance regulator channel function through phosphorylation-dependent and phosphorylation-independent mechanisms: The role of bilayer material properties
(AMER SOC PHARMACOLOGY EXPERIMENTAL THERAPEUTICS, 2006-12)2,3-Butanedione monoxime (BDM) is widely believed to act as a chemical phosphatase. We therefore examined the effects of BDM on the cystic fibrosis transmembrane regulator ( CFTR) Cl- channel, which is regulated by ... -
2-Aminoethyldiphenylborinate modifies the pulmonary circulation in pulmonary hypertensive newborn lambs partially gestated at high altitude
(Amer Physiological Soc., 2016-10)Calcium signaling through store-operated channels (SOC) is involved in hypoxic pulmonary hypertension. We determined whether a treatment with 2-aminoethyldiphenylborinate (2-APB), a compound with SOC blocker activity, ... -
2-hydroxyoestradiol and 2-methoxyoestradiol, two endogenous oestradiol metabolites, induce DNA fragmentation in Sertoli cells
(Blackwell, 2016)Elevated intratesticular levels of hydroxyoestradiols and methoxyoestradiols, two classes of endogenous oestradiol metabolites, have been associated with male infertility. The aim of this study was to explore the effects ... -
2-Methoxyestradiol in the human corpus luteum throughout the luteal phase and its influence on lutein cell steroidogenesis and angiogenic activity
(Elsevier, 2013-11)To quantitate 2-methoxyestradiol (2-ME) in human corpus luteum (CL) of different ages and to determine the expression of cytochrome-P450-1A1 (CYP1A1) and catechol-O-methyl transferase (COMT) in CL and the action of 2-ME ... -
2-Phenylaminonaphthoquinones and related compounds: Synthesis, trypanocidal and cytotoxic activities
(Elsevier, 2014)A series of new 2-aminonaphthoquinones and related compounds were synthesized and evaluated in vitro as trypanocidal and cytotoxic agents. Some tested compounds inhibited epimastigote growth and trypomastigote viability. ... -
24‐Year‐Old Woman with An Internal Auditory Canal Mass
(International Society of Neuropathology, 2013-05)Benign peripheral nerve sheath tumors are divided into schwannomas, neurofibromas and perineuriomas. In recent years, tumors with hybrid features, composed of multiple, discrete areas of different histological types, were ... -
3,4-dihydroxyphenylacetic acid, a microbiota-derived metabolite of quercetin, protects against pancreatic beta-cells dysfunction induced by high cholesterol
(Elsevier, 2015)Cholesterol plays an important role in inducing pancreatic beta-cell dysfunction, characterized by an impaired insulin secretory response to glucose, representing a hallmark of the transition from pre-diabetes to diabetes. ... -
A 10 gene classifier for indeterminate thyroid nodules: development and multicenter accuracy study
(Mary Ann Liebert, Inc., 2017)Background: In most of the world, diagnostic surgery remains the most frequent approach for indeterminate thyroid cytology. Although several molecular tests are available for testing in centralized commercial laboratories ... -

A chloride channel from human placenta reconstituted into giant liposomes
(Mosby-Year book, 1995)OBJECTIVE: Ion channels play important roles in epithelial transport, but they are difficult to access for conventional electrophysiologic studies in intact placenta. The purpose of this work was to explore the suitability ... -
A cholinergic gating mechanism controlled by competitive interactions in the optic tectum of the pigeon
(2007)We describe the operation of a midbrain neural circuit in pigeons that may participate in selecting and attending to one visual stimulus from the myriad displayed in their visual environment. This mechanism is based on a ... -
A cien años de la Psicopatología General de Jaspers. Su concepto del límite y sus relaciones con el posmodernismo
(Sociedad Chilena para el Desarrollo de la Psiquiatría, 2013)En 2013 se cumplen cien años de la primera edición de la Psicopatología General. Dicen los filósofos que Jaspers era psiquiatra y los psiquiatras, filósofos, de modo que todos despachan rápidamente el asunto y lo dan por ... -
A Circadian Clock Entrained by Melatonin Is Ticking in the Rat Fetal Adrenal
(ENDOCRINE SOC, 2011-05)The adrenal gland in the adult is a peripheral circadian clock involved in the coordination of energy intake and expenditure, required for adaptation to the external environment. During fetal life, a peripheral circadian ... -
A combined docosahexaenoic acid thyroid hormone protocol upregulates rat liver beta - Klotho expression and downstream components of FGF21 signaling as a potential novel approach to metabolic stress conditions
(Royal Society Chemistry, 2017)Liver preconditioning by a docosahexaenoic acid (DHA) and triiodothyronine (T-3) combined protocol underlies peroxisome-proliferator activated receptor alpha (PPAR alpha)-fibroblast growth factor 21 (FGF21) upregulation, ... -
A critical review of conscientious objection and decriminalisation of abortion in Chile
(BMJ Publishing Group, 2018)From 1989 through September 2017, Chile's highly restrictive abortion laws exposed women to victimisation and needlessly threatened their health, freedom and even lives. However, after decades of unsuccessful attempts to ... -
A decade of HAART in Latin America: Long term outcomes among the first wave of HIV patients to receive combination therapy
