Reprogramming of small noncoding RNA populations in peripheral blood reveals host biomarkers for latent and active Mycobacterium tuberculosis infection
(American Society for Microbiology, 2019)
Cognitive impairment in late-life bipolar disorder is not associated with Alzheimer's disease pathological signature in the cerebrospinal fluid
(2016-02-01)
Objectives: Cognitive impairment is a common feature of late-life bipolar disorder (BD). Yet, there is limited information on the biological mechanisms associated with this process. It is uncertain whether cognitively ...
Inhabited subsurface wet smectites in the hyperarid core of the Atacama Desert as an analog for the search for life on Mars
(Nature Research, 2020-12-01)
The modern Martian surface is unlikely to be habitable due to its extreme aridity among other environmental factors. This is the reason why the hyperarid core of the Atacama Desert has been studied as an analog for the ...
Preserved flora and organics in impact melt breccias
(Geological Society of America, 2014-06)
Impact cratering can destroy life from local to global scales and result in sudden turnovers of dominant genera and/or species. Here we report that it can also preserve components of the local biology present at the time ...
High stellar FUV/NUV ratio and oxygen contents in the atmospheres of potentially habitable planets
(Elsevier Science, 2014-01)
Recent observations of several planet-hosting M dwarfs show that most have FUV/NUV flux ratios 1000 times greater than that of the Sun. Here we show that the atmospheric oxygen contents (O2 and O3) of potentially habitable ...
Life is everywhere in sinters: examples from Jurassic hot-spring environments of Argentine Patagonia
(Cambridge University Press, 2019-07)
Jurassic siliceous hot-spring (sinter) deposits from Argentine Patagonia were evaluated to determine the distribution and preservation quality of their entombed microbial fabrics. Detailed study showed that the Claudia ...
Comprehensive plasma proteomic profiling reveals biomarkers for active tuberculosis
(American Society for Clinical Investigation, 2020)
BACKGROUND. Tuberculosis (TB) kills more people than any other infection, and new diagnostic tests to identify active cases are required. We aimed to discover and verify novel markers for TB in nondepleted plasma. METHODS. ...
Dysregulated Immune Activation in Second-Line HAART HIV+ Patients Is Similar to That of Untreated Patients

Circulating Biomarkers of Immune Activation, Oxidative Stress and Inflammation Characterize Severe Canine Visceral Leishmaniasis
