TASK DEFINITION: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
PROBLEM: Question: Do an update in the palliative management of malignant dysphagia?
Answer: Palliative treatment for oesophageal cancer should be individualized and relate to tumour stage, size and location, the patient's medical condition and his/her personal wishes. The palliative treatment largely includes self-expanding metal stents (SEMS), laser (including photodynamic therapy (PDT)) or a combination of the two to relieve symptoms, this may be employed with or without other treatments such as radiotherapy/chemotherapy (RT/CT) with the aim of reducing tumour bulk and possibly prolonging survival. A multi-disciplinary approach is vital in patients with advanced oesophageal cancer.

SOLUTION: yes

PROBLEM: Question: Does unloading of baroreceptors by carotid occlusion increase heart rate in fetal sheep?
Answer: We conclude that in contrast to adult animals, in fetal sheep carotid occlusion with subsequent unloading of baroreceptors does not increase heart rate even when the baroreflex had been activated by arterial hypertension. It seems likely that stimulation of carotid chemoreceptors prevents the expected baroreceptor mediated heart-rate response.

SOLUTION: no

PROBLEM: Question: Does deletion of the G6pc2 gene encoding the islet-specific glucose-6-phosphatase catalytic subunit-related protein affect the progression or incidence of type 1 diabetes in NOD/ShiLtJ mice?
Answer: These results demonstrate that G6pc2 is an important driver for the selection and expansion of islet-reactive CD8(+) T cells infiltrating NOD/ShiLtJ islets. However, autoreactivity to G6pc2 is not essential for the emergence of autoimmune diabetes. The results remain consistent with previous studies indicating that insulin may be the primary autoimmune target, at least in NOD/ShiLtJ mice.

SOLUTION:
no
