N′-[(E)-(5-Bromo-2-hydroxyphenyl)(phenyl)methylidene]-4-chlorobenzohydrazide
The Schiff base, C20H14BrClN2O2, displays a trans conformation with respect to the C=N double bond. The aromatic rings at either end of the –C(=O)–NH–N=C– fragment are nearly parallel [dihedral angle = 3.4 (5)°]. The hydroxy group forms an intramolecular hydrogen bond to the imino N atom
Outcomes of treatment of sudden deafness using different Protocols: a retrospective analysis of 104 cases
AbstractObjectiveTo compare different treatment protocols for sudden deafness(SD), for the purpose of identifying an appropriate approach to SD.MethodsA total of 104 patients with diagnosis of sudden hearing loss treated from Jan 2006 to December 2008 were included in this study, of which 31 received the typical pharmaceutical treatment(group I), 40 received the typical pharmaceutical treatment plus polarized liquid(Group II) and 33 received the hyperbaric oxygen in addition to the treatment included in Group II (Group III).ResultsThe total improvement rate(67.74%, 62.50% and 75.76% for Groups I, II and III respectively) was not statistically different between the three groups (P>0.05).ConclusionThe three treatment protocols are similar when judged by the treatment outcomes in SD, neither being superior to the others. The two important factors that appear to influence treatment outcomes are the audiogram pattern and duration of hearing loss before seeking treatment. Patients with upsloping or peak–type audiograms and treated within 7 days from the onset have better prognosis than others

A case-control study on the dietary taurine intake, nutrient status and life stress of functional constipation patients in Korean male college students
Dietary taurine intake, nutrients intake, dietary habits and life stress by depression in Korean female college students: a case-control study
<p>Abstract</p> <p>Background</p> <p>The purpose of this study was to investigate the dietary taurine intake, nutrients intake, dietary habits and life stress by depression in Korean female college students.</p> <p>Methods</p> <p>In this study, research data were collected in March 2009 and 65 patients with depression and 65 controls without depression participated. The CES-D (Center for Epidemiologic Studies Depression) scale was used for depression measure and controls were matched for age. A 3-day recall method was used for dietary assessment (2 weekdays and 1 weekend day).</p> <p>Results</p> <p>Average height, weight and body mass index (BMI) were 161.3±0.5cm, 55.3±1.0kg and 21.2±0.4kg/m<sup>2</sup> for depression patients and those of control group were 161.4±0.7cm, 53.1±0.8kg and 20.3±0.2kg/m<sup>2</sup>, respectively. Average dietary taurine intakes of depression patients and control group were 89.1 and 88.0 mg/day, respectively. There was no significant difference in dietary taurine intake between depression patients and control group. The average intakes of vitamin A (p<0.05), β-carotene (p<0.01), vitamin C (p<0.05), folic acid (p<0.05) and fiber (p<0.05) of depression patients were significantly lower compared to control group. The average total dietary habit score of depression patients (47.2) was significantly lower than that of control group (51.3) (p<0.01). The average dietary habit scores of “eating meals at regular times” (p<0.05), “eating adequate amount of meals” (p<0.05), “having meals with diverse foods” (p<0.05), “avoiding eating spicy foods” (p<0.01) and “eating protein foods such as meat, fish, eggs, beans more than 2 times a day” (p<0.05) were significantly lower in depression patients compare to control group. The average scores of total life stress (p<0.001) and all stress categories of depression patients were significantly higher than those of control group except faculty problem score.</p> <p>Conclusions</p> <p>These results show that depression patients have poor dietary habits and unbalanced nutrition status. Also depression patients have higher life stress score.</p> <p>Therefore, continuous nutrition education and counselling for good dietary habits and balanced nutrition status are needed to prevent depression in Korean college students.</p
N′-[(E)-1-(5-Bromo-2-hydroxyphenyl)ethylidene]benzohydrazide
The C=N double bond in the title compound, C15H13BrN2O2, is trans

(5-Bromo-2-hydroxyphenyl)(phenyl)methanone
In the title compound, C13H9BrO2, the dihedral angle between the aromatic ring planes is 53.6 (1)°. The crystal structure is stabilized by intramolecular O—H⋯O and intermolecular C—H⋯O hydrogen bonding and C—H⋯π interactions
(meso-5,7,7,12,14,14-Hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene)nickel(II) bis[O,O′-bis(4-methylphenyl) dithiophosphate]
In the title compound, [Ni(C16H32N4)](C14H14O2PS2)2 or [Ni(trans[14]dien)][S2P(OC6H4Me-4)2]2, where trans[14]dien is meso-5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene, the NiII ion lies across a centre of inversion and is four-coordinated in a relatively undistorted square-planar arrangement by the four N atoms of the macrocyclic ligand trans[14]dien. The two O,O′-di(4-methylphenyl)dithiophosphates act as counter-ions to balance the charge. Important geometric data include Ni—N = 1.9135 (16) and 1.9364 (15) Å
{N′-[(E)-(5-Bromo-2-oxidophenyl)(phenyl)methylene]benzohydrazidato}pyridinenickel(II)
