-
(Elsevier, 2014)Proteins involved in bacterial cell division often do not have a counterpart in eukaryotic cells and they are essential for the survival of the bacteria. The genetic accessibility of many bacterial species in combination with ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2010-04-08)The Atacama Desert, located in northern Chile, is one of the driest deserts on the Earth. However, in some years, short and sporadic rainfall in the southern end of this desert has increased the soil moisture that produces ...
-
(American Society for Microbiology, 2017)Bacteria of the genus Prosthecobacter express homologs of eukaryotic alpha- and beta-tubulin, called BtubA and BtubB (BtubA/B), that have been observed to assemble into filaments in the presence of GTP. BtubA/B polymers ...
-
(Oxford University Press, 2018)High-elevation lakes in the tropics are subject to extreme environmental fluctuations and microbes may harbor a unique genomic repertoire, but their composition and diversity are largely unknown. Here, we compared the ...
-
(Elsevier Ltd, 1996)Four new meroterpene derivatives have been isolated in a bioassay- guided study of the methanol extract of the leaves of Psoralea glandulosa, in addition to the known compounds bakuchiol and angelicin. Structures for the ...
-
(Springer-Verlag, 1990)We studied the energetics of two herbivorous desert rodents from South America. The two species had slightly lower basal metabolic rates, lower thermal conductances, and higher temperature differentials than those expected ...
-
(Elsevier, 2014)Glucocorticoids are essential for life and their secretion is regulated by the hypothalamic–pituitary–adrenal axis (HPA). The HPA axis is often divided into two components: baseline glucocorticoids levels and stress ...
-
(2011)The interaction of bisperhalophenyl aurates [AuR2]- (R = C6F5, C6F3Cl2, and C6Cl5) with the closed-shell Ag+, Cu+, and Tl+ ions has been studied theoretically and compared with the experimentally known X-ray diffraction ...
-
(2002)To facilitate a rational basis set selection for B3LYP studies of organic reactions in the interstellar medium, we analyzed energetic parameters for the main stationary points in the reaction HN=CH2 + •C≡N → H2N-C(•)H-C≡N ...
-
(Elsevier, 1999)In this work, the basis set superposition error (BSSE) has been analyzed for the systems Cu2, Cu3, Cu6 and Cu13 as prototypes of metallic clusters. Various basis sets have been tested. In addition, pseudopotentials of 1- ...
-
(Kluwer Academic Publishers, 1977)The dietary composition of the antarctic fish Notothenia gibberifrons Lönnberg in a depth gradient was studied, from sea level until 200 meters in South Bay, Doumer Island, West Antarctic. The diet of this species varied ...
-
(CELL PRESS, 2009-03-27)Adaptation to endoplasmic reticulum (ER) stress depends on the activation of an integrated signal transduction pathway known as the unfolded protein response (UPR). Bax inhibitor-1 (BI-1) is an evolutionarily conserved ...
-
(Springer, 2015)In this work we review the formalism used in describing the thermodynamics of first-order phase transitions from the point of view of maximum entropy inference. We present the concepts of transition temperature, latent ...
-
(1992)The solubility behavior in water of different salts of cetyltrimethyl ammonium (CTA+), such as iodide (CTAI), thiocyanate (CTASCN), and perchlorate (CTAClO4), is reported. The order of solubilities is CTASCN > CTAI > ...
-
(1990)The behavior of dental tissues from the rabbit, Oryctolagus cuniculus, in association with epithelium from the quail, Coturnix coturnix japonica, has been examined. Adult and embryo rabbits were employed in this study. ...
-
(IOS Press, 2018)Alzheimer's disease (AD) is the most frequent type of dementia in the elderly, severely affecting functional and executive skills of subjects suffering from this disease. Moreover, the distress of caregivers as well as the ...
-
(2002)The exact mechanism of cell death in neurodegenerative diseases remains obscure, although there is evidence that their pathogenesis may involve the formation of free radicals originating from the oxidative metabolism of ...
-
(Elsevier, 2019)Triadimefon (TDF) is a triazole fungicide extensively used in agriculture that has been found as a pollutant in numerous water sources. In mammals, it inhibits monoamine uptake through binding to the dopamine transporter, ...
-
(AMER PSYCHOLOGICAL ASSOC, 2010-06-30)3,4-methylenedioxymethamphetamine (MDMA; “ecstasy”) is a psychoactive drug structurally related to other phenylisopropylamines acting as stimulants or hallucinogens in humans. Although MDMA has a pharmacological identity ...
