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).

[Q]: 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.

[Q]: 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.

[Q]: Abstract: Prazosin, an antagonist of the alpha 1-adrenoceptor, has been found to suppress the clinical and histologic expression of experimental autoimmune encephalomyelitis (EAE) in the Lewis rat. This effect appears to be specific for the alpha 1-receptor. To determine the effect of this drug on vascular permeability to serum proteins and inflammatory cells, leakage of serum proteins into the central nervous system (CNS) was measured with [125I]albumin, and quantitation of cellular inflammation was determined by an estimation of total DNA. The results show that in both actively induced and passively transferred models of the disease, treatment with prazosin significantly suppresses leakage of serum proteins into the CNS but does not significantly suppress the increase of DNA. The results of the [125I]albumin studies additionally support the conclusion that the extent of vascular permeability to serum proteins in the spinal cord is a significant correlate of clinical disease. The results of the DNA estimation were at variance with the histologic evidence of cellular infiltration. We conclude that treatment with prazosin has a significant effect on the development of vascular edema in EAE. These results additionally validate a role for the adrenergic receptor in the development of EAE, and support the hypothesis that the primary site of action of prazosin is on the vascular alpha 1-adrenoceptor.
Which is the apt title for the abstract? option1: Prazosin treatment suppresses increased vascular permeability in both acute and passively transferred experimental autoimmune encephalomyelitis in the Lewis rat. option2: The v-fms oncogene induces factor independence and tumorigenicity in CSF-1 dependent macrophage cell line.
