It is well known that most patients with obstructive sleep apnoea/hypopnoea syndrome (OSAHS) suffer sleepiness, although the underlying mechanisms of this relationship remain unclear. The present study examined the relationship between nocturnal variables and the subsequent waking electroencephalogram (EEG), in order to determine if sleepiness was related to OSAHS severity and due to sleep fragmentation or to nocturnal hypoxaemia.In total, 12 moderate-to-severe OSAHS patients underwent a total sleep night followed by a 24-h period of sustained wakefulness where the waking EEG was measured every hour.The results showed that alpha (7.9-12.6 Hz) and beta (12.7-29.2 Hz) activities were strongly related to OSAHS severity, mainly reflected by the apnoea index. Moreover, spectral power in most of the waking EEG components was significantly correlated with nocturnal hypoxaemia indices, namely alpha and beta activity when hypoxaemia becomes severe. However, no correlation was found between the waking EEG and sleep fragmentation parameters.In conclusion, the present results suggest that the difficulty in maintaining an optimal level of alertness, reflected by a higher activity in awake alpha and beta bands (7.9-29.2 Hz) in obstructive sleep apnoea/hypopnoea syndrome, was better explained by: 1) the apnoea as opposed to the hypopnoea index; and 2) nocturnal hypoxaemia as opposed to sleep fragmentation.

Our results revealed a significant correlation between C282Y and H63D mutations and the development of CAD in T2D patients.

Introduction: An increase in the consumption of antibiotics has raised significant concerns over the treatment of Klebsiella pneumonia-infected patients. In this study, the resistance pattern of K. pneumoniae to antibiotics such as imipenem, meropenem, and ertapenem, as well as the frequency of Metallo-beta-lactamase (MBL) genes, namely VIM, IMP, and NDM-1 were investigated. Methods: Following the isolation of 200 K. pneumoniae isolates from 650 clinical samples, the antibiotic resistance pattern of these isolates against different antibiotics was evaluated. The isolates resistant to imipenem, meropenem, and ertapenem were identified, and the presence of VIM, IMP, and NDM-1 genes was examined by using PCR methods. Results: The K. pneumoniae isolates exhibited different resistance patterns in response to various antibiotics. The frequency of VIM, IMP, and NDM-1 genes showed that 48 strains are resistant to imipenem, meropenem, and ertapenem in which 15.6% was positive for IMP, 2.42% for VIM, and 1.92% positive for NDM-1 gene. The isolates showed the highest antibiotic resistance to ampicillin (97.5%) and the lowest to meropenem (5.5%). Conclusion: Considering carbapenem antibiotics such as imipenem, meropenem, and ertapenem which are known to be among the most frequently used antibiotics for the treatment of K. pneumoniae infections and the involvement of MBL genes in this scenario, we aimed to screen and identify MBL genes responsible for the resistance of K. pneumoniae to imipenem, meropenem, and ertapenem.

Aims: Propolis is one of the natural materials collected by the honeybees. The material is extensively used to treat some diseases. The aim of this study was to determine the effects of ethanol extract of propolis of Qazvin plain on some biochemical factors, as well as serum antioxidant capacity, in adult male Wistar rats. Materials & Methods: In the experimental study, 40 adult male Wistar rats were divided into four groups (n=10 per group). The first was control group. The experimental groups received 50, 100, and 200mg/kg propolis. After 10day gavage, the serum of the rats being extracted, glucose, triglyceride, aspartate aminotransferase, alanine aminotransferase, and total antioxidant capacity were measured. Data was analyzed by SPSS 20 software using one-way ANOVA and Tykey's post-hoc tests. Findings: There was no significant difference in the blood sugar level between different groups and control group. There was a significant reduction in triglyceride level in "100mg/kg" group than control group (p<0.001). There was a significant increase in aspartate aminotransferase level in "100mg/kg" (p<0.01) and "200mg/kg" (p<0.001) groups. There was a significant reduction in alanine aminotransferase level in "50mg/kg" group (p<0.001). Propolis led to a significant increase in the total antioxidant capacity of serum, especially at 50mg/kg (p<0.05) and 100mg/kg (p<0.01) doses. Conclusion: Oral consumption of propolis has a moderating effect on some blood biochemical factors especially triglyceride. In addition, it increases serum total antioxidant capacity. Nevertheless, its excessive consumption might damage patients with liver diseases.
