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.

Input: Consider Input: Anal intraepithelial neoplasia precedes the development of anal squamous cell carcinoma. Detection of the lesion is essential to management. This paper describes a prospective study to detect and ablate anal squamous intraepithelial lesions (SILs) using white light narrow band imaging (NBI) and NBI with acetic acid (NBIA).', 'Sixty patients with abnormal anal cytology and risk factors for anal dysplasia underwent examination of the anoderm with a high definition gastroscope and NBIA. Targeted biopsies were taken and the lesions were ablated and characterized histopathologically. Visualization of the anal transitional zone was facilitated by retroflexion and examination through a disposable anoscope.', 'Targeted biopsies were taken from lesions in 58 patients. No lesion was seen in two patients. Histopathology showed SIL in 48 (80.0%) of 60 biopsies. One biopsy showed lymphoid aggregates. Biopsies in nine (15%) of the 60 patients showed normal mucosa. Lesions were seen in white light in 27 (45%) of the 60 cases, NBI in 39 (65%) and NBIA in 57 (95%). There was no major morbidity. Sensitivity analysis showed that all methods were significantly different from each other.

Output: Is detection of anal dysplasia enhanced by narrow band imaging and acetic acid?


Input: Consider Input: An effective HIV vaccine will likely require induction of both mucosal and systemic cellular and humoral immune responses. We investigated whether intramuscular (IM) delivery of electroporated plasmid DNA vaccine and simultaneous protein vaccinations by intranasal (IN) and IM routes could be combined to induce mucosal and systemic cellular and humoral immune responses to a model HIV-1 CN54 gp140 antigen in mice.', 'Co-immunisation of DNA with intranasal protein successfully elicited both serum and vaginal IgG and IgA responses, whereas DNA and IM protein co-delivery did not induce systemic or mucosal IgA responses. Cellular IFNγ responses were preserved in co-immunisation protocols compared to protein-only vaccination groups. The addition of DNA to IN protein vaccination reduced the strong Th2 bias observed with IN protein vaccination alone. Luminex analysis also revealed that co-immunisation with DNA and IN protein induced expression of cytokines that promote B-cell function, generation of TFH cells and CCR5 ligands that can reduce HIV infectivity.

Output: Does plasmid DNA Vaccine Co-Immunisation modulate Cellular and Humoral Immune Responses Induced by Intranasal Inoculation in Mice?


Input: Consider Input: To explore the importance of follicle-stimulating hormone receptor (FSHR) in granulosa cells in the ovarian response to gonadotropin stimulation.', 'Prospective study.', "A women's hospital in China.", 'One hundred infertile women undergoing ovarian stimulation with recombinant follicle-stimulating hormone (rFSH).', 'These women were divided into three groups: poor, moderate, and high responders, according to the number of follicles with diameter >/=14 mm. The FSHR expression at both mRNA and protein levels was determined by either reverse transcription-polymerase chain reaction or Western blot in granulosa cells. E(2) concentrations in serum and FSH levels in serum/follicular fluid (FF) were measured by electrochemiluminescence immunoassay.', 'Relative expression of mRNA and protein of FSHR in granulosa cells, serum E(2), FSH level in serum and FF, and the number of mature follicles.', 'The expression of FSHR, at both the mRNA and protein levels, was significantly different among the three groups, with the lowest expression in the poor responders. The level of FSHR protein was positively correlated with the peak level of serum E(2) and the number of mature oocytes. FSH levels in FF and the dosage of rFSH used were significantly different among the three groups, with the highest values in the poor responders.


Output: Is poor ovarian response to gonadotropin stimulation associated with low expression of follicle-stimulating hormone receptor in granulosa cells?
