Caracterización de patrones alimentarios durante la pandemia por COVID 19 en Chile
(2022-04)Background: Confinement to prevent contagion by COVID-19 has been shown to have a negative impact on different components of the population's health, food being one of the most notable. The objective of this work was to ... -
Ultra-processed food and homemade fried food consumption is associated with overweight/obesity in Latin American university students during COVID-19
(2023)Objective: We estimated the association between the consumption of select ultra-processed food (UPF), homemade fried food and overweight/obesity in Latin American university undergraduate students during the COVID-19 ... -
Asociacion entre nivel de Actividad Física, y Motivacion en personas mayores que practican Running
(2022)The objective of the study was To associate the Level of Physical Activity and Motivation in Older People (OP) who practice Running, with variables of Sex and Age. An observational cross-sectional study was carried out. A ... -
Asociación entre nutrientes y hemoglobina glicosilada en diabéticos tipo 2
(2016)Introduction: Hyperglycemia is the main characteristic of diabetes (DM). CHO restriction in diet has the greatest effect decreasing blood glucose levels in both type 1 and 2 DM. Objective: To associate intake of macro and ... -
Solitonic self-sustained charge and energy transport on the superconducting cylinder
(2023-03-15)We present an exact time-dependent solution for a charged scalar field on a two-dimensional cylinder, that can be interpreted as representing a long-standing excitation on a S-wave superconducting state, which propagates ... -
Denervation Drives YAP/TAZ Activation in Muscular Fibro/Adipogenic Progenitors
(2023-03)Loss of motoneuron innervation (denervation) is a hallmark of neurodegeneration and aging of the skeletal muscle. Denervation induces fibrosis, a response attributed to the activation and expansion of resident fibro/adipogenic ... -
Activation of skeletal muscle FAPs by LPA requires the Hippo signaling via the FAK pathway
(2023-05)Lysophosphatidic acid (LPA) is a lysophospholipid that signals through six G-protein coupled receptors (LPARs), LPA1 to LPA6. LPA has been described as a potent modulator of fibrosis in different pathologies. In skeletal ... -
Aromaticity in P8 allotropes and (CH)8 analogues : significance of their 40 valence electrons?
(2023-03-07)The currently unknown phosphorus allotrope P8 is of interest since its 40 total valence electrons is a “magic number” corresponding to a filled 1S21P61D101S21F142P6 shell such as found in the relatively stable main group ... -
Infinitene as two fused helicoidal trails of fused rings : evaluation of the magnetic behavior of [12]infinitene and anionic species displaying global aromaticity and antiaromaticity
(2023-02-16)The unique formation of an infinity-shaped carbon backbone made exclusively from fused benzene rings has recently been achieved. The structure of [12]infinitene can be viewed as two fused [6]helicene structures with a ... -
On the Cation-π capabilities of infinitene (∞). Evaluation of bonding and circular dichroism properties for Infinitene-Ag(I)n (n = 1–4) complexes from relativistic DFT calculations
(2023-04-01)The helicoidal π-conjugated structure from helicenes is able to feature cation-π bonding towards Ag(I) atoms, resulting in the variation of their inherent high optical rotation values. Recently, the characterization of ... -
The interplay of d and f orbitals in the chemistry of the early actinides : High spin versus low spin
(2023-08-01)Early actinides lie at the borderline between d- and f-block elements. Here we describe the coordination capabilities of thorium featuring characteristics from both blocks. Thus analysis of the recently synthesized monoanion ... -
Intermediate Silver Doping of Au25(SR)18 : Variation of Electronic, Optical, and Chiroptical Properties along Au25-xAgx(SH)18- (x = 0-12) Stoichiometry from DFT Calculations
(2023-05-08)The silver analogue of the prominent Au25(SR)18 nanocluster reveals the possibility of finding “gold”-like behavior despite their different nature, in addition to the common features among molecular AgNP. Herein, we explore ... -
Size-dependent cellular uptake of sodium alginate passivated tin dioxide nanoparticles in triple-negative breast cancer cells
(2023-07-25)The new development of inorganic (IO) nanoparticle (NPs)-based nanomedicines in anticancer therapy is an active area of research. The cellular uptake of IO NPs plays a crucial role in their efficacy as anticancer agents. ... -
Hybrid nanomaterial composed of chitosan, curcumin, ZnO and TiO2 for antibacterial therapies
(2023-07-01)Metal nanoparticles have been tremendously utilised, such as; antibacterial and anticancer agents. Although metal nanoparticles exhibits antibacterial and anticancer activity, but the drawback of toxicity on normal cells ... -
