Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Input: Consider Input: We demonstrated previously that striatal adenosine modulates ethanol-induced motor incoordination (EIMI) via adenosine A1 receptors coupled to pertussis toxin (PT)-sensitive G protein and adenylyl cyclase-cyclic adenosine monophosphate (cAMP). Additionally, intrastriatal (IST) PT antagonizes EIMI and its potentiation by the adenosine A1 agonist N-cyclohexyladenosine; it also inhibits cAMP concentration.', 'Guide cannulas were stereotaxically implanted for IST pretreatment with PT followed 5 days later by IST of N-cyclohexyladenosine and intraperitoneal ethanol. The adenosine diphosphate (ADP) ribosylation reaction involved PT-catalyzed [P]nicotinamide adenine dinucleotide (NAD) labeling of rat striatal membranes. Antagonism of EIMI (Rotorod method) after IST microinfusion of PT was investigated to determine whether it was due to a decrease in the functional activity of G proteins due to ADP ribosylation of the Gialpha subunit caused it.', 'Striatal membranes from IST PT (0.5 microg)-treated animals exhibited significantly attenuated (up to 90%) in vitro ADP ribosylation with [P]NAD. Striatal membranes from animals injected with ethanol (1.5 g/kg intraperitoneally) exhibited statistically significant increase (11%) in in vitro ADP ribosylation. Similarly, ethanol (50 mM) added to striatal membranes from untreated animals produced significant stimulation of in vitro ADP ribosylation. The decrease in the functional activity of G proteins due to ADP ribosylation of the Gialpha subunit after IST PT was functionally correlated with marked attenuation in EIMI, as observed previously. This finding suggests a blockade of functional activity of PT-sensitive striatal Gi/Go proteins (i.e., fewer available sites for labeled NAD incorporation). The in vivo ethanol results indicate that it must have caused an increase in the ribosylation capacity of Gialpha in vivo (i.e., increased Gi activity). Increased ADP ribosylation by in vitro ethanol increases Gi/Go activity, consistent with EIMI, as previously reported.

Input: Consider Input: Intravenous tissue-type plasminogen activator (tPA) is a proven treatment for acute ischemic stroke, but there has been limited evaluation among patients aged ≥90 years.', 'We analyzed data from the Get With The Guidelines-Stroke national quality improvement registry from January 2009 to April 2013. Frequency, determinants, and outcomes of tPA use were compared among patients aged ≥90 and 3 younger age groups (18-64, 65-79, and 80-89 years).', 'Among 35\u2009708 patients from 1178 sites who arrived within 2 hours of time last known well and received tPA, 2585 (7.2%) were ≥90 years. Compared with younger patients, the rate of tPA use among patients without a documented contraindication was lower among patients aged ≥90 years (67.4% versus 84.1% in 18-89-year olds; P<0.0001). Discharge outcomes among individuals aged ≥90 years included discharge to home or acute rehabilitation in 31.4%, independent ambulation at discharge in 13.4%, symptomatic hemorrhage in 6.1%, and in-hospital mortality or hospice discharge in 36.4%. On multivariable analysis, good functional outcomes generally occurred less often and mortality more often among patients aged ≥90 years. The risk of symptomatic hemorrhage was increased compared with patients <65 years but was not significantly different than the risk in 66- to 89-year olds.

Input: Consider Input: Adequate visualization of the placenta or umbilical cord during fetoscopic procedures in complicated monochorionic twin pregnancies may be difficult because of placental position and spatial constraints, as well as stained amniotic fluid. Partial amniotic carbon dioxide insufflation (PACI) has made it possible to overcome these obstacles in other fetoscopic procedures, but its value has not yet been reported in monochorionic twins.', 'Partial amniotic carbon dioxide insufflation was carried out in five expectant women with complicated monochorionic twin pregnancies between 19 + 6 to 29 + 4 weeks of gestation when adequate fetoscopic visualization of pathological placental surface vessels or the umbilical cord was impossible because of stained or too little amniotic fluid. In four cases, five fetoscopic laser ablations of pathological placental vessels in twin-to-twin transfusion syndrome (TTTS) were performed. In one discordant twin pregnancy with TTTS, PACI was carried out in order to achieve umbilical cord ligation in a recipient with omphalocele and cardiac malformation.', 'Partial amniotic carbon dioxide insufflation offered superior visualization and did not result in any acute maternal or fetal complications. After fetoscopic laser coagulation, three women delivered one fetus at 27 + 5, two fetuses at 28 + 6, and two fetuses at 35 + 4 weeks of gestation, respectively. One set of twins with TTTS was lost. Following umbilical cord ligation, the surviving twin was delivered at 37 + 2 weeks of gestation.
