  • Cell navigation is the process whereby cells or cytoplasmic extensions are guided from one point to another in multicellular organisms or, in the case of unicellular eukaryotic organisms, in the environment. Recent work has demonstrated that membrane trafficking plays an important role in this process.

  • After the first edition published in 2007 that became a best seller, the continuous scientific developments in the field have prompted us to produce the second edition of this book. As it happens in life and science, some of the novel and promising data presented in the first edition have been confirmed, some not, and new breakthrough achievements have been accomplished. Stem Cells in Reproductive Medicine, Basic Science and Therapeutic Potential, second edition, updates the revolutionary advances in stem cell science that may potentially impact on human reproductive medicine.

  • FC01 CELLS Cells are tiny building blocks that make up all living things. Cells are so small that you need a microscope to see them. ANIMAL CELL This is the control centre of the cell. It contains chromosomes with DNA instructions for all the cell’s activities, including instructions to make new cells. This is a jelly like substance, in which many of the cell’s activities, e.g. respiration and protein synthesis occur. This is a thin skin around the cell. It is selectivelt permeable, controlling what goes in and out of the cell....

  • Control analysis of the glycolytic flux was carried out in two fast-growth tumor cell types of human and rodent origin (HeLa and AS-30D, respect-ively). Determination of the maximal velocity (Vmax) of the 10 glycolytic enzymes from hexokinase to lactate dehydrogenase revealed that hexokin-ase (153–306 times) and phosphfructokinase-1 (PFK-1) (22–56 times) had higher over-expression in rat AS-30D hepatoma cells than in normal freshly isolated rat hepatocytes.

  • Angiomotin, an 80 kDa protein expressed in endothelial cells, promotes cell migration and invasion, and stabilizes tube formationin vitro. Angiomotin belongs to a new protein family with two additional members, Amotl-1 and Amotl-2, which are characterized by conserved coiled-coil domains and C-terminal PDZ binding motifs.

  • Invasive Disease The treatment of a tumor that has invaded muscle can be separated into control of the primary tumor and, depending on the pathologic findings at surgery, systemic chemotherapy. Radical cystectomy is the standard, although in selected cases a bladder-sparing approach is used; this approach includes complete endoscopic resection; partial cystectomy; or a combination of resection, systemic chemotherapy, and external beam radiation therapy. In some countries, external beam radiation therapy is considered standard.

  • Complications Following Hematopoietic Cell Transplant Early Direct Chemoradiotoxicities The transplant preparative regimens commonly used cause a spectrum of acute toxicities that vary according to the specific regimen but frequently result in nausea, vomiting, and mild skin erythema (Fig. 108-1). Regimens that include high-dose cyclophosphamide can result in hemorrhagic cystitis, which can usually be prevented by bladder irrigation or with the sulfhydryl compound mercaptoethanesulfonate (MESNA); rarely, acute hemorrhagic carditis is seen.

  • Tuberculosis has been a major cause of illness and death in the Philippines yet TB control efforts have historically, been fragmented and uncoordinated. The National TB Control Program of the Department of Health has made significant advances in improving the quality and extent of its control efforts but the private sector and even other departments of government have not been integrated into the overall TB control activities.

  • The Ras⁄Raf⁄extracellular signal-regulated kinase (ERK) signaling path-way plays a crucial role in almost all cell functions and therefore requires exquisite control of its spatiotemporal activity. Depending on the cell type and stimulus, ERK activity will mediate different antiproliferative events, such as apoptosis, autophagy and senescence in vitro and in vivo.

  • Many protein substrates of caspases are cleaved at noncanonical sites in comparison to the recognition motifs reported for the three caspase sub-groups. To provide insight into the specificity and aid in the design of drugs to control cell death, crystal structures of caspase-7 were determined in complexes with six peptide analogs (Ac-DMQD-Cho, Ac-DQMD-Cho, Ac-DNLD-Cho, Ac-IEPD-Cho, Ac-ESMD-Cho, Ac-WEHD-Cho) that span the major recognition motifs of the three subgroups.
