AbstractPolyamines are ubiquitous small basic molecules that play multiple
essential roles in mammalian physiology. Their cellular content is highly
regulated and there is convincing evidence that altered metabolism is
involvement in many disease states. Drugs altering polyamine levels may
therefore have a variety of important targets. This review will summarize the
current state of understanding ... hiện toàn bộ
AbstractThe antibacterial activity of honey has been known since the 19th
century. Recently, the potent activity of honey against antibiotic‐resistant
bacteria has further increased the interest for application of honey, but
incomplete knowledge of the antibacterial activity is a major obstacle for
clinical applicability. The high sugar concentration, hydrogen peroxide, and the
low pH are well‐kno... hiện toàn bộ
Tóm tắtCác glycerophospholipid phosphatidylcholine (PC) và
phosphatidylethanolamine (PE) chiếm hơn 50% tổng số loài phospholipid trong màng
eukaryote và do đó đóng vai trò quan trọng trong cấu trúc và chức năng của các
màng này. Trong hầu hết các tế bào eukaryote, PC và PE được tổng hợp thông qua
phản ứng aminocoholphosphotransferase, sử dụng sn‐1,2‐diradylglycerol và
CDP‐choline hoặc CDP‐ethanola... hiện toàn bộ
AbstractMonocarboxylate transporter (MCT) isoforms 1–4 catalyze the
proton‐linked transport of monocarboxylates such as L‐lactate across the plasma
membrane, whereas MCT8 and MCT10 are thyroid hormone and aromatic amino acid
transporters, respectively. The importance of MCTs is becoming increasingly
evident as their extensive physiological and pathological roles are revealed.
MCTs 1–4 play essenti... hiện toàn bộ

AbstractThe long term use of many insecticides is continually threatened by the
ability of insects to evolve resistance mechanisms that render the chemicals
ineffective. Such resistance poses a serious threat to insect pest control both
in the UK and worldwide. Resistance may result from either an increase in the
ability of the insect to detoxify the insecticide or by changes in the target
protein... hiện toàn bộ
AbstractGlucose‐6‐phosphate dehydrogenase (G6PD) is the rate‐limiting enzyme of
the pentose phosphate pathway. Many scientists think that the roles and
regulation of G6PD in physiology and pathophysiology have been well established
as the enzyme was first identified 80 years ago. And that G6PD has been
extensively studied especially with respect to G6PD deficiency and its
association with hemolysi... hiện toàn bộ
AbstractThe c‐Jun N‐terminal kinases (JNKs) were originally identified by their
ability to phosphorylate c‐Jun in response to UV‐irradiation, but now are
recognized as critical regulators of various aspects of mammalian physiology,
including: cell proliferation, cell survival, cell death, DNA repair and
metabolism. JNK‐mediated phosphorylation enhances the ability of c‐Jun, a
component of the AP‐1... hiện toàn bộ
AbstractIncreasing evidence suggests a role for intracellular reactive oxygen
species (ROS) as mediators of normal and pathological signal transduction
pathways. In particular, a growing list of recent reports have demonstrated a
rapid and significant increases in intracellular ROS following growth factor or
cytokine stimulation. These ROS appear essential for a host of downstream
signaling events... hiện toàn bộ
