Lifetime suicidal thoughts, attempts, and lethality of attempts as major outcome domains of psychotic disorders: a 21-year prospective cohort study after a first-episode psychosis
Background: Suicidal thoughts and behaviors (STBs) are a major concern in people with psychotic disorders. There is a need to examine their prevalence over long-term follow-up after first-episode psychosis (FEP) and determine ...
Cyclin A1 is essential for setting the pluripotent state and reducing tumorigenicity of induced pluripotent stem cells
The proper differentiation and threat of cancer rising from the application of induced pluripotent stem (iPS) cells are major bottlenecks in the field and are thought to be inherently linked to the pluripotent nature of ...
Increased dosage of tumor suppressors limits the tumorigenicity of iPS cells without affecting their pluripotency
Embryonic stem (ES) cells and induced pluripotent stem (iPS) cells represent a promising therapeutic tool for many diseases, including aged tissues and organs at high risk of failure. However, the intrinsic self-renewal ...
GNIP1 E3 ubiquitin ligase is a novel player in regulating glycogen metabolism in skeletal muscle.
Background: Glycogenin-interacting protein 1 (GNIP1) is a tripartite motif (TRIM) protein with E3 ubiquitin ligase activity that interacts with glycogenin. These data suggest that GNIP1 could play a major role in the control ...
Stable and Efficient Genetic Modification of Cells in the Adult Mouse V-SVZ for the Analysis of Neural Stem Cell Autonomous and Non-autonomous Effects
Relatively quiescent somatic stem cells support life-long cell renewal in most adult tissues. Neural stem cells in the adult mammalian brain are restricted to two specific neurogenic niches: the subgranular zone of the ...
Using iPS Cells toward the Understanding of Parkinson's Disease
Cellular reprogramming of somatic cells to human pluripotent stem cells (iPSC) represents an efficient tool for in vitro modeling of human brain diseases and provides an innovative opportunity in the identification of new ...
Access to Enantiopure Advanced Intermediates en Route to Madangamines
The synthesis of enantiopure ABCE and ABCD tetracyclic advanced intermediates en route to madangamine alkaloids and studies for the construction of the triunsaturated 15-membered D ring of madangamine B and the saturated ...
Lyophilized Maqui (Aristotelia chilensis) Berry Induces Browning in the Subcutaneous White Adipose Tissue and Ameliorates the Insulin Resistance in High Fat Diet-Induced Obese Mice
Maqui (Aristotelia Chilensis) berry features a unique profile of anthocyanidins that includes high amounts of delphinidin-3-O-sambubioside-5-O-glucoside and delphinidin-3-O-sambubioside and has shown positive effects on ...
Validation of the CAchexia SCOre (CASCO). Staging Cancer Patients: The Use of miniCASCO as a Simplified Tool
The CAchexia SCOre (CASCO) was described as a tool for the staging of cachectic cancer patients. The aim of this study is to show the metric properties of CASCO in order to classify cachectic cancer patients into three ...
A low-protein diet induces body weight loss and browning of subcutaneous white adipose tissue through enhanced expression of hepatic Fibroblast Growth Factor 21 (FGF21).
Scope: Fibroblast growth factor 21 (FGF21) is considered a promising therapeutic candidate for the treatment of obesity. Since FGF21 production is regulated by various nutritional factors, we analyze the impact of low ...

Liver X receptors and inflammatory-induced C/EBPβ selectively cooperate to control CD38 transcription
Introduction: Macrophages abundantly express liver X receptors (LXRs), which are ligand-dependent transcription factors and sensors of several cholesterol metabolites. In response to agonists, LXRs promote the expression ...
Caveolin interaction governs Kv1.3 lipid raft targeting
The spatial localization of ion channels at the cell surface is crucial for their functional role. Many channels localize in lipid raft microdomains, which are enriched in cholesterol and sphingolipids. Caveolae, specific ...
Neuropilin-2 upregulation by stromal TGFβ1 induces lung disseminated tumor cells dormancy escape and promotes metastasis outgrowth
Metastasis is the main cause of death from solid tumors. Therefore, identifying the mechanisms that govern metastatic growth poses a major biomedical challenge. Tumor microenvironment signals regulate the fate and survival ...
Fine tuning the extracellular environment accelerates the derivation of kidney organoids from human pluripotent stem cells
The generation of organoids is one of the biggest scientific advances in regenerative medicine. Here, by lengthening the time that human pluripotent stem cells (hPSCs) were exposed to a three-dimensional microenvironment, ...
Ubiquitination mediates Kv1.3 endocytosis as a mechanism for protein Kinase C-dependent modulation
The voltage-dependent potassium channel Kv1.3 plays essential physiological functions in the immune system. Kv1.3, regulating the membrane potential, facilitates downstream Ca2+ -dependent pathways and becomes concentrated ...
The Ninth data release of the Sloan Digital Sky Survey: first spectroscopic data from the SDSS-III Baryon Oscillation Spectroscopic Survey
The Sloan Digital Sky Survey III (SDSS-III) presents the first spectroscopic data from the Baryon Oscillation Spectroscopic Survey (BOSS). This ninth data release (DR9) of the SDSS project includes 535,995 new galaxy spectra ...
Constraints on deviations from ΛCDM within Horndeski gravity.
Recent anomalies found in cosmological datasets such as the low multipoles of the Cosmic Microwave Background or the low redshift amplitude and growth of clustering measured by e.g., abundance of galaxy clusters and redshift ...
Understanding the mechanism of direct activation of AMP-kinase: Towards a fine allosteric tuning of the kinase activity
This research deals with the regulation of the AMPK activity by direct activators, such as compound A-769662. AMPK is a key enzyme to maintain the cellular energy homeostasis, as it regulates the levels of ATP, being an ...
Enantioselective Synthesis of Spiro[indolizidine-1,3 '-oxindoles]
A three-step procedure for the enantioselective synthesis of spiro[indolizidine-1,3'-oxindoles], consisting of a stereoselective cyclocondensation reaction between (S)-tryptophanol and a prochiral or racemic 5-oxoester, ...
