Input: Consider Input: Context: Chronic stress is generally known to exacerbate the development of numerous neuropsychiatric diseases such as fear and anxiety disorders, which is at least partially due to the disinhibition of amygdala subsequent to the prolonged stress exposure. GABA receptor A (GABAAR) mediates the primary component of inhibition in brain and its activation produces two forms of inhibition: the phasic and tonic inhibition. While both of them are critically engaged in limiting the activity of amygdala, their roles in the amygdala disinhibition subsequent to chronic stress exposure are largely unknown.', 'We investigated the possible alterations of phasic and tonic GABAAR currents and their roles in the amygdala disinhibition subsequent to chronic stress. We found that both chronic immobilization and unpredictable stress led to long lasting loss of tonic GABAAR currents in the projection neurons of lateral amygdala. By contrast, the phasic GABAAR currents, as measured by the spontaneous inhibitory postsynaptic currents, were virtually unaltered. The loss of tonic inhibition varied with the duration of daily stress and the total days of stress exposure. It was prevented by pretreatment with metyrapone to block corticosterone synthesis or RU 38486, a glucocorticoid receptor antagonist, suggesting the critical involvement of glucocorticoid receptor activation. Moreover, chronic treatment with corticosterone mimicked the effect of chronic stress and reduced the tonic inhibition in lateral amygdala of control mice. The loss of tonic inhibition resulted in the impaired GABAergic gating on neuronal excitability in amygdala, which was prevented by metyrapone pretreatment.
Answer: Our study suggests that enduring loss of tonic but not phasic GABAAR currents critically contributes to the prolonged amygdala disinhibition subsequent to chronic stress. We propose that the preferential loss of tonic inhibition may account for the development of stress-related neuropsychiatric diseases.

Output: Does chronic stress impair GABAergic control of amygdala through suppressing the tonic GABAA receptor currents?


Input: Consider Input: Context: To assessdoctor's knowledge on the relevance of the problem of sleep disorders, methods of their diagnosis and treatment.", 'The survey was conducted among90physicians of different the rapeuticspecialties of Kazan medical institutions.', 'The doctors believe that main causes of sleep disorders are stressors (20%), depression (13%), neurosis (13%), chronic diseases (13%), asthenia (10%), pain (10%). An analysis of treatment prescribed to patients with sleep disorders revealed large differences.
Answer: Physicians are not well informed about the problems of sleep disorders, have a small idea of the methods of sleepresearch and drugs for their treatment as well as of a sequence of operations that should be used to resolve this problem.

Output: Do [ What do the doctors of different specialties know about sleep disorders and their treatment ]?


Input: Consider Input: Context: Severe alcoholic hepatitis occurs mainly in patients with cirrhosis, and has a high death rate. Corticosteroid therapy has been particularly advocated as reducing mortality in patients with severe histologic lesions. However, identification of these patients is difficult, requiring transvenous liver biopsy. Extracellular matrix serum markers have been proposed as non-invasive diagnostic tools in alcoholic liver disease. The aim of this study was to determine the accuracy of 5 extracellular matrix serum markers, i.e. laminin (Lam), N-terminal peptide of type III procollagen (PIIINP), type I (CI), type III (CIII) and type IV (CIV) collagens in identifying patients with severe histologic alcoholic hepatitis from among those with cirrhosis and suspected alcoholic hepatitis.', "We studied 80 consecutive patients with alcoholic cirrhosis and clinical suspicion of alcoholic hepatitis referred for transvenous liver biopsy. Clinical severity of alcoholic hepatitis was assessed according to Maddrey's score. Histological severity was scored using the sum of the 3 following items: polynuclear infiltration (0-3); hepatocytes alterations (0-3); Mallory bodies (0-2). According to this score, patients were divided into 3 groups: mild (1-3), moderate (4-6), and severe (7-8) alcoholic hepatitis. Serum levels of the 5 extracellular matrix serum markers were measured at the time of biopsy using radioimmunoassays. Diagnostic value for histologically severe alcoholic hepatitis of the 5 extracellular matrix serum markers was assessed using receiver operating characteristic curves.", "Histological alcoholic hepatitis was present in 67 patients (mean alcoholic hepatitis score: 3.4+/-2.3). Maddrey's score was 66% sensitive and 69% specific for the diagnosis of severe histologic alcoholic hepatitis. The serum Lam and CIV concentrations were the most accurate in identifying correctly patients with severe histologic alcoholic hepatitis. At a cut-off of 4.1 UI/ml, Lam was 90% sensitive and 77% specific, whereas at a cut-off of 150 ng/ml, CIV was 89% sensitive and 77% specific. Combination of markers did not result in improved diagnostic value.
Answer: In patients with cirrhosis, determination of serum Lam or CIV could represent a simple and accurate non-invasive method for identification of patients with histologically severe alcoholic hepatitis eligible for corticosteroid treatment.


Output: Are serum laminin and type IV collagen accurate markers of histologically severe alcoholic hepatitis in patients with cirrhosis?
