Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).

Example Input: Abstract: For the treatment of familial hypercholesterolemia, Liposorber LA-40 was clinically applied. The Liposorber is a commercially developed affinity adsorbent for plasma perfusion which selectivity adsorbs low density lipoproteins and very low density lipoproteins and is specially designed for plasmapheretic treatment of hypercholesterolemia. The Liposorber column, containing activated cellulose beads having an affinity for lipoprotein containing apolipoprotein-B, has an excellent adsorption capacity, excellent selectivity, minimum albumin loss. This new apheresis system was applied to 2 clinical cases. After seven months of trial perfusion every 2 weeks, patient condition was good, with a level of total cholesterol under 300 mg/dl. No replacement fluids were given during or after treatment. In this paper, clinical results of these patients were shown and the mechanism of adsorption of this specific adsorbent was discussed.
Which is the apt title for the abstract? option1: Adsorption of lipoprotein containing apolipoprotein-B through plasma separation for treatment of familial hypercholesterolemia. option2: Increase in AIDS-associated illnesses focuses new attention on an old nemesis [news]
Example Output: Adsorption of lipoprotein containing apolipoprotein-B through plasma separation for treatment of familial hypercholesterolemia.

Example Input: Abstract: An emergency environmental health investigation of a mass poisoning of unknown origin is a multidiscipline effort that requires the cooperation and close communication of epidemiologists, toxicologists, and chemists. The laboratory's role in this effort is important; special instruments, knowledge, and experience are needed. Our approach to such an investigation is discussed and past cases are used as illustrations. The role of the analytical chemist is presented, and the major resources needed for these investigations are described.
Which is the apt title for the abstract? option1: The laboratory's role in environmental health emergency investigations. option2: Selective screening device for the early detection of normal or delayed cognitive development in infants at risk for later mental retardation.
Example Output: The laboratory's role in environmental health emergency investigations.

Example Input: Abstract: To summarize the results: Bilirubin removal by hemoperfusion was successfully performed for the first time on a premature infant. The hemoperfusion caused no adverse effects on the clinical state of the infant. The bilirubin removed in 90 min--13 mg--indicates the existence of a large extravascular pool. Hemoperfusion is suggested for bilirubin removal from newborn babies, reducing the need for blood exchange with bank blood.
Which is the apt title for the abstract? option1: Bilirubin removal from a jaundiced premature infant by resin hemoperfusion. option2: The potential role of common dermatologic practice technics in transmitting disease [letter]
Example Output:
Bilirubin removal from a jaundiced premature infant by resin hemoperfusion.
