  2020-02-26

  

  E1 is a classical initiator protein and, as such, plays several roles in the initiation and catalysis of viral DNA synthesis. E1 must first recognize a specific segment of the viral Dextran sulfate sodium salt known as the “origin of DNA replication”, or “ori” for short. For most PV types examined

  QSAR based on the 3D structures of ligands plays an important role in the ligand-based drug discovery and design [12]. Comparative molecular field analysis, CoMFA [11], and comparative molecular similarity index analysis, CoMSIA [12] are among the most popular QSAR models. They focus on changes in 3

  Introduction The endeavor to achieve a successful use of commercial-off-the-shelf (COTS) electronic devices in space is not new and the reasons are well known [1], [2], [3]. More recently, COTS have been widely employed in the manufacturing of low-cost, small satellites, for scientific and even c

  The availabilities of serotonin and dopamine are modulated by the serotonin transporter and catechol-O-methyltransferase enzyme. The serotonin transporter (5-HTT) is a key protein that reuptakes serotonin from the synaptic cleft back into synaptic boutons (Coleman et al., 2016; Talvenheimo et al., 1

  Synthetic progestogens (also known as ‘synthetic gestagens’, ‘synthetic progestins’ or simply ‘progestins’) are designed to mimic the effects of progesterone (P4) and are the active pharmaceutical ingredient in many contraceptives and hormone replacement therapies. Since most progestins are derived

  Introduction Breast cancer is a highly prevalent malignancy. There are some recognized risk factors for breast cancer, like early menarche or late menopause, which increase the length of the exposure to hormones, as a result of a higher number of ovarian cycles [1]. Moreover, there is evidence supp

  Conclusions ERK 1/2 and its phosphorylation plays an essential role in the hippocampus and can be triggered by both ROS accumulation and excessive Ca2+. DBP exposure can also affect the production of ROS and Ca2+ in the hippocampus. The question therefore arises as to whether the cell injury or a

  Halogenases Enzymatic C–H activation leading to halogenation is another emerging area in biocatalysis [55,56]. Incorporation of halogen atoms during medicinal chemistry eff ;orts is a well-established practice, presenting an effective means to control the molecule’s bioactivity and physicochemical

  The structure of the HOIP RBR–LDD module bound to UbcH5~Ub reveals insights into an activated HOIP component [47]. Contacts between the E2~Ub and the non-cognate RBR module in the crystal suggest how a structure in which the active sites of the E2 and the E3 are in close proximity might look. In thi

  Introduction The number of patients with type 2 diabetes is increasing globally, and has become a serious public health problem. Type 2 diabetic patients exhibit a higher risk of bone fracture [1]. In addition, clinical studies have indicated that increased fracture risk is associated with long-ter

  Our results implicate a critical role for CXCR-1 in promoting the migration of colonic tumor cells. Expression of this receptor, but not CXCR-2, increased significantly because of the EMT (Fig. 3). Moreover, although Clone A WH-4-023 express comparable levels of both IL-8 receptors, only CXCR-1 inh
