  Several 16-dehidropregnenolone derivatives functionalized at C3, C4, C5 and C6 (Fig. 7) were prepared and evaluated as 5α-reductase inhibitors bearing in mind that after the formation of an enzyme-steroid complex a nucleophilic portion of the enzyme attacks the double bond of the steroid through Mic

  2024-08-15

  

  Many coumarin derivatives can be found in nature. There are more than 1300 types of those purely derived from plants, and if synthetic products are included, their number is immeasurable. According to the earliest existing records extant, herbs containing Psoralen-type compounds, e.g., methoxsalen,

  Here the so-called alkali assay [18] is proposed as a method to be applied directly on the purified recombinant enzyme sharing the same structural and functional features of the wild-type enzyme [19], [20], [21] using its physiological substrate androstenedione. The assay that was already successful

  The apocrine sweat glands of the human axilla produce odor substances with pheromone functions whose nature corresponds to volatile steroids (Cowley and Brooksbank, 1991, Grosser et al., 2000, Sobel et al., 1999, Weller, 1998). These functions only begin with puberty, indicating that sex hormones st

  2024-08-15

  

  AMPK as a druggable target AMPK signaling has attracted considerable attention within the past decades, owing to the capacity of pharmacological compounds (e.g., 5-aminoimidazole-4-carboxamide-1-β-D-ribofuranoside [AICAR] and metformin) or natural compounds (e.g., resveratrol) to activate AMPK in

  2024-08-15

  

  A characteristic of iron present in brain fluids is considerable differences between measured values of ferritin and transferrin and the total iron content value (Table 1). Variation of the latter is compatible with differences in individual metabolisms. However differences between total iron conten

  2024-08-15

  

  As one of emerging high-throughout methods, metabolomics detects metabolites which are ultimate response of biological systems to environmental changes [14]. Metabolomics uncovers metabolic alteration at the systems level. Comparison of global metabolic profiling reflects some unidentified biologica

  While the mechanisms by which ALDH2 regulates cardiac responses to pathological stress remain unclear, the capillary rarefaction found in pressure-overloaded ALDH2 Tg hearts provides potential clues. Loss of capillary density and diminished endothelial function occur in pathological hypertrophy [46]

  However, there are a lot of external magnetic field disturbances in urban environments, for example when the AHRS is close to a ferrous or magnetic object, which will disturb the output of magnetometer, then the observational errors cannot satisfy the assumption of Kalman filtering, and so, the atti

  Heart failure is a chronic syndrome in which the heart is unable of pumping an adequate supply of blood to meet the metabolic requirements of the body or generating the required elevated ventricular filling pressures to maintain output [34]. Despite considerable advances in the treatment of heart fa

  There are several reports about the expression of AChRs and their modulation to osteogenic factors in osteoblasts (Rothem et al., 2011, Sato et al., 2010, Walker et al., 2001). The normal osteocytic MLO-Y4 BS-181 HCl expressed multiple subtypes, which was demonstrated by the detection of M1, M2, M5,

  Using our infection assays, we also explored whether low-pH compartments were required for the entry of ZIKVs in mammalian cells. Lysosomotropic agents such as ammonium chloride, chloroquine and Bafilomycin A1, strongly inhibited the ability of ZIKVs to enter mammalian cells. Our results are in agre

  Regulators of the DDR have therefore become attractive targets for cancer therapy primarily through two potential approaches. First, to be used as chemo- or radiosensitisers to increase the effectiveness of standard genotoxic treatments and to help prevent or overcome the development of resistance.
