Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

[EX Q]: To investigate the prevalence and temporal development of N-methyl-d-aspartate receptor (NMDAR) autoantibodies in relation to neurocognitive performance in patients with herpes simplex encephalitis (HSE).', "This prospective observational study enrolled a total of 49 HSE patients within a randomized controlled trial of valacyclovir. Cerebrospinal fluid and serum samples were drawn in the initial stage of disease, after 2 to 3\xa0weeks and after 3\xa0months. Anti-NMDAR IgG was detected with HEK293\xa0cells transfected with plasmids encoding the NMDA NR1 type glutamate receptor. A batch of neurocognitive tests, including the Mattis Dementia Rating Scale (MDRS), Glasgow Coma Scale (GCS), Reaction Level Scale (RLS85), Mini-Mental State Examination (MMSE) and National Institutes of Health (NIH) stroke scale, was performed during 24\xa0months' follow-up.", "Anti-NMDAR IgG was detected in 12 of 49 participants. None were antibody positive in the initial stage of disease. In ten of 12 positive cases, specific antibodies were detectable only after 3\xa0months. Notably, the development of NMDAR autoantibodies was associated with significantly impaired recovery of neurocognitive performance. After 24\xa0months' follow-up, the median increase in MDRS total score was 1.5 vs. 10 points in antibody-positive and -negative participants (p=0.018).

[EX Q]: The purpose of the present study was to evaluate the detection rate of genomic aberrations in haematological malignancies using oligobased array-CGH (oaCGH) analysis in combination with karyotyping and fluorescence in situ hybridization (FISH) analyses, and its feasibility in a clinical pragmatic approach.', 'The 4x180K Cancer Cytochip array was applied in 96 patients with various haematological malignancies in a prospective setting and in 41 acute myeloid leukemia (AML) patients retrospectively.', 'Combined use of oaCGH analysis and karyotyping improved the overall detection rate in comparison to karyotyping-alone and vice versa. In cases with normal karyotypes oaCGH analysis detected genomic aberrations in 66% (39/60) of cases. In the group of simple karyotypes oaCGH analysis extended karyotypic findings in 39% (12/31) while oaCGH analysis extended the karyotypic findings in 89% (39/44) of cases with complex karyotypes. In 7% (5/75) of cases oaCGH analysis failed in detecting the observed abnormalities by karyotyping.

[EX Q]: Caffeine is frequently used during pregnancy and associated with teratogenic effects, such as low birth weight, hearth and digital defects, cleft palate and abortion with fetal loss. This study investigated histopathologically the effects of caffeine on neonatal rat cornea.', 'Fifty pregnant Wistar-Albino rats (dams) were randomly divided into five groups, one control and four experimental. Between day 9 and 21 of gestation, group 1 dams (control, n=10) were exposed to intraperitoneal (i.p.) SF daily until delivery. Group 2 (n=10), group 3 (n=10) and group 4 (n=10) dams were treated with i.p. caffeine at doses of 25, 50 and 100 mg/kg/d, respectively, for the same period. Group 5 dams were given caffeine in distilled water in a gavage at a dose of 50 mg/kg/d during the same period. After normal delivery, the litters were killed at postnatal day 1 or 30 and the eyes were enucleated for corneal histopathologic investigation.', 'Control and group 1 eyes had normal corneal epithelium, regular stromal fibers, descement membrane and monolayer inner corneal endothelium. The remaining experimental litters demonstrated changes, such as vacuolated endothelial cells with proliferation, hyperchromasia, polymorphism, endothelial cell agenesis, increased stromal mitotic activity and focal increase in corneal thickness with widely separated corneal lamellae in the injured area. These changes occurred most often in the litters treated with high doses of caffeine.
