(1990)Spontaneous intramural hematoma of the esophagus (SIHE) is a rare condition usually affecting middle-aged or elderly women. It presents as acute substernal or epigastric pain, typically accompanied by dysphagia or hematemesis. ...

Early holocene climate change and human occupation along the semiarid coast of north-central Chile (2010)The brief, terminal Pleistocene archaeological site at Santa Julia (SJ, 318 500 S; 718 450 W) is the only one with fluted projectile preforms and megafauna consumption known from the Chilean semiarid coastline. Here, we ...

(2011-03)Researchers in the High Andes in northern Chile report the study of a fine cave sequence, supported by 19 radiocarbon dates. The initial occupation at c. 11 500 cal BP represents the earliest human occupation known ...
-
(1993)BACKGROUND: Hepatitis B vaccine has demonstrated to be very effective and safe preventing hepatitis B virus infection. Long term protection induced by hepatitis B vaccination depends on the initial immune response and the ...

High- and low-latitude forcings drive Atacama desert rainfall variations over the past 16,000 years (Amer Assoc Advancement Science, 2021)Late Quaternary precipitation dynamics in the central Andes have been linked to both high- and low-latitude atmospheric teleconnections. We use present-day relationships between fecal pellet diameters from ashy chinchilla rats ...
-
(Wiley, 2015)Archaeological sites composed only of surficial lithics are widespread in arid environments. Numerical dating of such sites is challenging, however, and even establishing a relative chronology can be daunting. One potentially ...
-
(1993)Batrachotoxin-modified Na+ channels from toad muscle were inserted into planar lipid bilayers composed of neutral phospholipids. Single-channel conductances were measured for [Na+] ranging between 0.4 mM and 3 M. When ...
-
(Wiley, 2015)Aim In deserts, past climate change (and particularly past rainfall variability) plays a large role in explaining current plant species distributions. We ask which species were most and which were least affected by changes ...
-
(1987)Large unitary conductance Ca2+-activated K+ channels from smooth muscle membrane were incorporated into phospholipid planar bilayers, and the blockade induced by internally and externally applied Cs+ was characterized. ...
-
(1992)Collagenous and microscopic colitis have been described as causes for abundant watery diarrhea with a normal radiologic and endoscopic aspect of the colonic mucosa. Microscopic colitis is characterized by diffuse intraepithelial ...

(2011)Sudamérica cuenta con evidencias de ocupación humana desde los 14.600 años calibrados a.p. (14,6 ka). Sin embargo, en el desierto de Atacama existe una notoria ausencia de ocupaciones pre-11,5 ka entre las latitudes 17° ...

(1990)We randomized 31 cirrhotic patients with tense ascites to a Group A receiving only diuretic therapy (spironolactone, furosemide, n = 14) or a Group B treated with paracentesis and intravenous albumin infusion (n = 17). ...
-
(NATL ACAD SCIENCES, 2007-12-11)A large fraction of the vital groundwater in the Atacama Desert of northern Chile is likely composed of "fossil" or "ancient" reserves that receive little or no recharge in today's hyperarid climate. Here, we present ...
-
(JOHN WILEY & SONS LTD, 2005-07)Precipitation in northern Chile is controlled by two great wind belts-the southern westerlies over the southern Atacama and points south (>24 degrees S) and the tropical easterlies over the northern and central Atacama ...
-
(1992)Pre S2 was investigated using a monoclonal ELISA in 100 samples from 52 patients with different forms of infection with Hepatitis B virus. Pre S2 was present in 18 of 19 patients with acute hepatitis. Its persistence for ...

(1990)Primary biliary cirrhosis is a chronic, progressive and often fatal cholestatic liver disease. We report clinical characteristics and follow up in 33 consecutive patients studied at a single university hospital during the ...
