  • In receptor-mediated sorting of soluble protein ligands in the endomem-brane system of eukaryotic cells, three completely different receptor pro-teins for mammalian (mannose 6-phosphate receptor), yeast (Vps10p) and plant cells (vacuolar sorting receptor; VSR) have in common the features of pH-dependent ligand binding and receptor recycling.

  • Harrison's Internal Medicine Chapter 29. Disorders of the Eye The Human Visual System The visual system provides a supremely efficient means for the rapid assimilation of information from the environment to aid in the guidance of behavior. The act of seeing begins with the capture of images focused by the cornea and lens upon a light-sensitive membrane in the back of the eye, called the retina. The retina is actually part of the brain, banished to the periphery to serve as a transducer for the conversion of patterns of light energy into neuronal signals.

  • Red or Painful Eye Corneal Abrasions These are seen best by placing a drop of fluorescein in the eye and looking with the slit lamp using a cobalt-blue light. A penlight with a blue filter will suffice if no slit lamp is available. Damage to the corneal epithelium is revealed by yellow fluorescence of the exposed basement membrane underlying the epithelium. It is important to check for foreign bodies. To search the conjunctival fornices, the lower lid should be pulled down and the upper lid everted.

  • Microbial contamination of drinking-water contributes to disease outbreaks and background rates of disease in developed and developing countries worldwide. Control of waterborne disease is an important element of public health policy and an objective of water suppliers.

  • Water Excretion In contrast to the ingestion of water, its excretion is tightly regulated by physiologic factors. The principal determinant of renal water excretion is arginine vasopressin (AVP; formerly antidiuretic hormone), a polypeptide synthesized in the supraoptic and paraventricular nuclei of the hypothalamus and secreted by the posterior pituitary gland.

  • Prognostic Factors The most important prognostic factor is the stage at the time of presentation. Fortunately, most melanomas are diagnosed in clinical stages I and II. The revised American Joint Committee on Cancer (AJCC) staging system for melanoma is based on microscopic primary tumor depth (Breslow's thickness), presence of ulceration, evidence of nodal involvement, and presence of metastatic disease to internal sites (Table 83-3). Certain anatomic sites may affect the prognosis.

  • Management The entire cutaneous surface, including the scalp and mucous membranes, should be examined in each patient. Bright room illumination is important, and a 7x to 10x hand lens is helpful for evaluating variation in pigment pattern. A history of relevant risk factors should be elicited. Any suspicious lesions should be biopsied, evaluated by a specialist, or recorded by chart and/or photography for follow-up. Examination of the lymph nodes and palpation of the abdominal viscera are part of the staging examination for suspected melanoma.

  • Numerous virus–target cell interactions have been described, and it is now clear that different viruses can use similar host-cell receptors for entry. The list of certain and likely host receptors for viral pathogens is long. Among the host membrane components that can serve as receptors for viruses are sialic acids, gangliosides, glycosaminoglycans, integrins and other members of the immunoglobulin superfamily, histocompatibility antigens, and regulators and receptors for complement components.

  • Internal Rate of Return (IRR) is the discount rate at which the Present Value of future cash flows equals the initial capital invested (i.e. the discount rate at which the Net Present Value of a series of cash flows equals 0) expressed as a percentage. An IRR less than your targeted rate of return suggests you are paying too much for the property to get your targeted rate of return An IRR greater than your target rate of return suggests you could pay more for the property and still get your targeted rate of return E.g....

  • The prospect of human cloning has been one of the most emotive and divisive issues to face UN negotiators and the international community in recent years. Despite widespread consensus amongst nations regarding the desirability of banning reproductive cloning, efforts to negotiate an international convention ground to a halt due to fundamental divisions regarding so-called research or therapeutic cloning.

  • The Agile family of development methodologies was born out of a belief that an approach more grounded in human reality would yield better results. Agile emphasizes building working software that people can get hands on with quickly, versus spending a lot of time writing specifications up front. Agile focuses on small, cross-functional teams empowered to make decisions, versus big hierarchies and compartmentalization by function, and Agile focuses on rapid iteration, with as much customer input along the way as possible.

  • Ear anatomy. A. Drawing of modified coronal section through external ear and temporal bone, with structures of the middle and inner ear demonstrated. B. High-resolution view of inner ear. Stereocilia of the hair cells of the organ of Corti, which rests on the basilar membrane, are in contact with the tectorial membrane and are deformed by the traveling wave. A point of maximal displacement of the basilar membrane is determined by the frequency of the stimulating tone. High-frequency tones cause maximal displacement of the basilar membrane near the base of the cochlea.

  • Lichen Planus Lichen planus (LP) is a papulosquamous disorder that may affect the skin, scalp, nails, and mucous membranes. The primary cutaneous lesions are pruritic, polygonal, flat-topped, violaceous papules. Close examination of the surface of these papules often reveals a network of gray lines (Wickham's striae). The skin lesions may occur anywhere but have a predilection for the wrists, shins, lower back, and genitalia (Fig. 53-5).

  • Chronic Granulomatous Disease Chronic granulomatous disease (CGD) is a group of disorders of granulocyte and monocyte oxidative metabolism. Although CGD is rare, with an incidence of 1 in 200,000 individuals, it is an important model of defective neutrophil oxidative metabolism. Most often CGD is inherited as an X-linked recessive trait; 30% of patients inherit the disease in an autosomal recessive pattern. Mutations in the genes for the four proteins that assemble at the plasma membrane account for all patients with CGD.

  • Pain Pain occurs with variable frequency in the cancer patient: 25–50% of patients present with pain at diagnosis, 33% have pain associated with treatment, and 75% have pain with progressive disease. The pain may have several causes. In ~70% of cases, pain is caused by the tumor itself—by invasion of bone, nerves, blood vessels, or mucous membranes or obstruction of a hollow viscus or duct.

  • PI3K is a heterodimeric lipid kinase that catalyses the conversion of phosphatidylinositol bisphosphate (PIP2) to phosphatidylinositol trisphosphate (PIP3), which acts as a plasma membrane docking site for proteins that contain a pleckstrin homology (PH) domain. These include the serine/threonine kinases Akt and PDK1 that are key downstream effectors of PI3K action (Fig. 80-2). The PI3K pathway is activated in 30–40% of human cancers and is thought to play a critical role in tumor cell survival, proliferation, growth, and glucose utilization.
