Abstract
Introductioni Glycation is a non enzymatic
reaction initiated by the primary addition of
sugar to the amino groups of proteins.In the
early stage of glycation, the synthesis of
intermediates leading to formation of
Amadori compounds occurs. In the late
stage, advanced glycation end product
(AGE)is irrevesibly formed after a complex
cascade of reactions. Glycation also affect
diabetes-related complications
physiological aging and neurodegenerative
diseases such as alzeimers.
Materials & Methodsi In this study, HSA
incubation with glucose and different
concentration of papaverine for 42 days at
37°C. as well as HSA incubation alone
(control sample), with glucose(glycated
sample)were treated respectively under the
same conditions. After 42 days, the samples
by use of circular dichroism, fluorescence
and UV spectroscopy were investigated.
Findingsi HSA glycation increases alon
with rising of papaverine concentration.
Samples containing papaverine showed
more changes in secondary structure free
amino groups and AGE fluorescence in
relation to glycated and control samples.
Discussion & Conclusion: In glycated
helix and sheet a 5.7% decrease and 3.1%
increase were seen in comparison to the
control respectively. Glycated showed
14.2% fluorescence more than the control.
Free lys number in glycated showed 8%
less in relation to the control. All this cases
showed more changes in samples which
contained papaverine. HSA absorb in
presence of papaverine showed that
papaverine cause more lys contact with
sugar and an increase in glycation.

Abstract
Objectives: Sleep quality has neurobehavioral consequences that impact academic performance. Irregular and insufficient sleep habits and time inevitably leads to sleep problems. The aim of this survey was to understand of correlation between sleep quality with sleep habits and times among college students. Methods: Simple random sampling was used to select 80 students from the entire Iranshahr faculty of medical sciences for this cross sectional study. Bed time, sleep latency, waking time and nap time of participants during 1 month recorded. In the end of month, students were asked to complete Pittsburgh Sleep Quality Index questionnaires. Then, all of them interviewed by the someone. Results: Individuals with good sleep quality went to bed at 23:12, awoke at 6:14 and had 8.05 h total sleep time (TST) .There were positive and significant correlation between sleep quality with sleep latency and bed time. And also, there were a negative correlation (p<0.005, r=-0. 33) between sleep quality and TST. Rise time and nap time were not correlated with sleep quality. Conclusion: Selecting appropriate sleep time and following sufficient and regular sleep habits increase the sleep quality.

Abstract
Introduction: Frozen shoulder syndrome is a pathological condition associated with pain and restricted glenohumeral joint movement. It is divided into two types: idiopathic and secondary. The present study aimed to compare pain, as well as the condition of the cervical and dorsal spine, in patients with idiopathic and secondary frozen shoulder syndrome.
Material & Methods: This analytical observational study was conducted on 25 women with idiopathic frozen shoulder and 30 women with secondary frozen shoulder, referring to clinics of Tabriz, who were purposively selected. The pain level was measured using a visual analog scale, the posture of the cervical spine was measured using a photograph, and the posture of the thoracic spine was measured using a flexible ruler. An independent t-test was performed to compare the mean values of the variables. The data were analyzed using SPSS software at a significance level of 0.05.
Results: The obtained results demonstrated that there was a significant difference in the comparison of pain between patients with idiopathic and secondary frozen shoulder (P=0.001). Nonetheless, the comparison of the posture of the cervical spine revealed no significant difference between the two groups (P=0.057). However, the thoracic spine arch was significantly higher in patients with idiopathic frozen shoulders than in the secondary group (P=0.002).
Discussion & Conclusion: Pain and thoracic spine arch were more common in idiopathic frozen shoulder patients than in secondary patients. Although the difference in the condition of the cervical spine in the two groups was not significant, it is generally necessary to evaluate the posture of the spine to treat the pain of patients with frozen shoulders, especially idiopathic patients.
