Abstract: The electromagnetic spectrum consists of radiant energy that is classified according to specific wavelengths. Man is constantly exposed to a portion of the electromagnetic spectrum, particularly to radiation in the ultraviolet, visible and infrared regions. The tissues of the eye and skin are particularly sensitive to the non-ionizing wavelengths of radiant energy. Although both tissues possess endogenous protective mechanisms to minimize the effects of such exposure, problems still occur due to the absorption of radiation. The cornea, lens and retina have been shown to be susceptible to damage from light in the ultraviolet, visible and infrared range. Part I of this two-part article examines the structures of the eye that are most susceptible to light damage; part II, which will be published in the next issue of the Journal, focuses on eye protection.
Which is the apt title for the abstract? option1: The potential damaging effects of light on the eye (Part I). option2: Increased compound 48/80 induced local histamine release from nonlesional skin of patients with chronic urticaria.
answer:
The potential damaging effects of light on the eye (Part I).

Abstract: We have assigned the rat GH gene to chromosome 10 and the rat PRL gene to chromosome 17. DNA from a series of mouse BWTG3 x rat hepatocyte somatic cell hybrids, each of which has retained a unique complement of rat chromosomes, was analyzed for the presence of rat GH and PRL genomic fragments by Southern blotting. Radiolabeled complementary DNAs (cDNAs) encoding rat GH and rat PRL were used as molecular probes. Based upon these assignments, we conclude that the evolutionarily related GH and PRL genes have been dispersed to different chromosomes in rat as in man.
Which is the apt title for the abstract? option1: The related genes encoding growth hormone and prolactin have been dispersed to chromosomes 10 and 17 in the rat. option2: A randomized study comparing a high and a standard dose of cisplatin in combination with etoposide in the treatment of advanced non-small-cell lung carcinoma.
answer:
The related genes encoding growth hormone and prolactin have been dispersed to chromosomes 10 and 17 in the rat.

Abstract: In cases of exposure to unknown substances, analyzing environmental or biological samples for elevated levels of toxicants can be extremely complex. We assessed a method for prioritizing toxic substances according to the agreement between toxic-specific and incident-reported signs and symptoms by analyzing 25 reported case histories of exposure to inorganic toxicants. In all but one case, this analysis scheme successfully prioritized toxicants for subsequent analysis. Despite its limitations, the scheme is a substantial improvement over other available methods.
Which is the apt title for the abstract? option1: Assessment of a scheme for prioritizing inorganic toxicants by using signs-and-symptoms analysis. option2: Pittsburgh Insulin-Dependent Diabetes Mellitus Morbidity and Mortality Study: physical activity and diabetic complications.
answer:
Assessment of a scheme for prioritizing inorganic toxicants by using signs-and-symptoms analysis.
