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).

Input: Consider Input: Abstract: Identifying the parathyroid glands is of fundamental importance in thyroid and parathyroid surgery. We found that intravenous infusion of methylene blue was beneficial in intraoperative identification of the parathyroid glands in patients undergoing surgery for hyperparathyroidism as well as total and bilateral subtotal thyroidectomy. The technique is safe and easy to use, and it clearly reduces the operative time. We suggest that it be used routinely in thyroid and parathyroid surgery.
Which is the apt title for the abstract? option1: Methylene blue infusion for intraoperative identification of the parathyroid glands. option2: MR-guided aspiration biopsy: needle design and clinical trials.

Output: Methylene blue infusion for intraoperative identification of the parathyroid glands.

Input: Consider Input: Abstract: Macroporous polystyrene and polyvinylpyridine beads with quaternary ammonium and tertiary groups were tailor-made for the adsorption of unconjugated bilirubin. In vitro studies in order to obtain high adsorption capacity, the synthesized macroporous resin should have an average pore size of about 160 A and with surface area as large as possible. As the crosslinking of the resin increased from 4%-40% the amount of bilirubin adsorbed increased from 0.17 mg/g to 2.0 mg/g. Resins containing strong basic groups have higher adsorption capacities than their corresponding weak base groups. Adsorption mechanism studies showed that both chemical and physical adsorption took place. Adsorption of bilirubin in plasma was some what lower than in buffer solution.
Which is the apt title for the abstract? option1: Removal of unconjugated bilirubin by macroreticular resin in hemoperfusion. option2: Small intestinal complications of diverticulitis of the sigmoid colon.

Output: Removal of unconjugated bilirubin by macroreticular resin in hemoperfusion.

Input: Consider Input: Abstract: In black patients seen at Baragwanath Hospital, Johannesburg, appendicitis occurs most frequently in the 10-19-year-old age group. There is a pronounced male bias. Parasitic ova in the appendix are very seldom observed (3.6%). Fecaliths, present in 20% of diseased appendices, are noted far less frequently than are reported for white patients (50%-75%). There are about two cases of appendicitis per 1,000 admissions of adults annually, a low frequency consistent with the tenfold differential of appendectomies reported to prevail in urban black and white adolescents. The progressively changing diet of urban blacks, currently low in fat and in dietary fiber, has not yet become associated with a marked increase in the occurrence of the disease (nor of most other noninfective bowel diseases).
Which is the apt title for the abstract? option1: Characteristics and occurrence of appendicitis in the black population in Johannesburg, South Africa. option2: Mathematics for natural hierarchy [news]
Output: Characteristics and occurrence of appendicitis in the black population in Johannesburg, South Africa.
