  In order to improve the methodology of the synthesis of steroidal derivatives, our goal was the investigation of aza-Michael addition of different N-nucleophiles to 16-dehydropregnenolone in the presence of [DBU][OAc] as catalyst and reaction medium. Michael addition of electron deficient steroidal

  2023-10-07

  

  Evidences have suggested that impairment of CK activity contributes to inhibition of Na+, K+-ATPase and H+-ATPase activities during infectious diseases, since these ATPases are dependent of ATP, as observed by Baldissera et al. [31] in fish experimentally infected by Aeromonas caviae. We observed th

  ATM is required for the proper function of the DNA-repair pathway in response to bleomycin-induced DNA damage in mammalian cells [55], [56]. Recent reports suggest that ATM activation by double-strand breaks leads to the subsequent ATR activation [57], [58], [59]. The recruitment of ATR to double-s

  There are however, concerns of potential side-effects that should also be taken into account. Even though some studies pointed towards a potentially greater radiosensitising effect in p53-deficient tumours, ATM inhibition radiosensitises CZC-25146 in general, which raises the concern of normal tiss

  2023-10-07

  

  Two critical determinants of receptor trafficking are found within the GABAB1 cytoplasmic tail: the di-leucine internalization signal (EKSRLL) (Margeta-Mitrovic et al., 2000, Restituito et al., 2005) and the ER retention signal (RSRR) (Calver et al., 2001, Margeta-Mitrovic et al., 2000, Pagano et al

  2023-10-07

  

  The growth of cancer can control by inhibiting the rate of cell proliferation or increasing the rate of selective apoptosis and effectiveness of anticancer agents varies according to genetic constitution of cancer. Hence, we investigated the anticancer activity of arginase against different kinds of

  Similar to the importance of MeJA in postharvest A. bisporus quality maintenance at 10°C storage (Meng et al., 2012a), MeJA was also observed to play a pivotal role in this event at 4°C storage. Cap opening is an important mushroom quality indicator (Braaksma et al., 1999). During postharvest storag

  Among steroid saponins, ginsenosides are the active components of ginseng, a well-known chinese medicinal plant. More than hundreds of different ginsenosides have been isolated from ginseng and have shown in the past to be membrane active substances and to influence the membrane by modulating lipid

  To clarify the molecular mechanism of maduramicin-induced apoptosis in chicken myocardial cells, the mRNA levels of bcl-2, bax, and cytochrome C, as well as the mRNA levels and activities of caspase-3/8/9 were determined. The mRNA expressions and activities of initiator casapase-9 and executioner ca

  Nanoparticles are submicrometric systems smaller than 1000 nm which high surface area and composite materials may allow their greater interaction with biological membranes and control of the drug release. These features are directly associated with the efficacy of treatment and the presence of adver

  Acknowledgements Introduction The angiogenic ocular conditions represent the most common cause of blindness in developed countries [1]. It can affect all ages, for example, retinopathy of prematurity (ROP) in infants [2], [3], diabetic retinopathy (DR) [4] in working age adults and age-related

  A phase I trial has recently evaluated enzalutamide, an anti-androgen agent, in patients with ER- and AR-positive advanced BC to estimate safety and tolerability of enzalutamide therapy alone or in association to anastrozole, exemestane or fulvestrant [65]. The results of major clinical trials with

  Material and methods Results Table 1 shows that in addition to Leu/CysAP and DPPIV, genes for AspAP, ArgAP, MetAP, APM and PSA are expressed in adipocytes. The kinetic parameters of these AP are also shown in Table 1, revealing that APM has the highest Vmax and catalytic efficiency (Kcat/Km),

  Introduction Lipoxygenases (LOXs) are key enzymes that catalyze the polyunsaturated fatty acids (PUFAs) such as arachidic Tranexamic Acid (AA), linoleic acid (LA) and others unsaturated fatty acids (Brash, 1999). LOXs are expressed in immune, neural, epithelial, tumor cells and other cells (Claess

  Pioneering studies on the immunomodulatory role of adenosine date back to the early ‘70 s of last century (Fig. 1), when the critical role of this nucleoside in shaping the development and the activity of several immune cell populations was first established [[18], [19], [20], [21], [22]].
