Get PDFInvestigation of the Effect of Black Pepper Powder on Microbiological and Physicochemical Properties of Processed Cheese
Get PDFABSTRACT: The recent tendency in cheese production is to produce flavored cheese using natural flavoring materials with nutritional and high-quality microbial value for human consumption. This research is aimed at investigating the microbiological and physicochemical properties of processed peppery cheese. Samples were kept
under the three temperatures of 6, 25 and 37°C; microbial and physicochemical evaluations were performed on the samples immediately after being produced, after the end of each month from the production date until 4 months, and one month after the expiration date. The test was performed using a sample of processed cheese without pepper powder. The used plan was quite random, and it was repeated for 3 times in every treatment. The results of
physicochemical analyses of peppery cheese compared to the control sample indicated that the peppery cheese had
lower changes in pH, dry matter content and texture during the period of being kept under different temperatures and less microbial contamination was observed in it compared to the control cheese. The obtained results showed that the peppery cheese could keep the product quality better than the control cheese under different time and temperature conditions of treatments while highly controlling the changes in the chemical and microbial factors

Get PDFRelationships between Severity of Internet Gaming Disorder, Severity of Problematic Social Media Use, Sleep Quality and Psychological Distress
Get PDFInternet gaming and social media use are prevalent and integral to many people’s lives. However, excessive engagement in either could lead to negative health impacts. This study aimed to investigate relationships between severities of internet gaming disorder (IGD) and problematic social media use (operationalized as social media addiction; SMA) with sleep quality and psychological distressamongyoungadults. Across-sectionalstudywithsnowballsamplingwasconductedamong Hong Kong university students in 2019. All participants (n = 300; mean (SD) age = 20.89 (1.48); 122 males(40.67%))respondedtoanonlinesurveythatincludedChineseversionsoftheInternetGaming Disorder Scale-Short Form (IGDS9-SF), Bergen Social Media Addiction Scale (BSMAS), Pittsburgh Sleep Quality Index (PSQI), and Depression Anxiety Stress Scales (DASS-21). Multiple linear regressionsdemonstratedthatIGDS-SF9scoresdemonstratedassociationswithpsychologicaldistress measures (standardized coefficient (β) = 0.295 for depression, 0.325 for anxiety, 0.339 for stress, all p < 0.001). BSMAS scores showed similar albeit numerically less robust associations (β = 0.235 for depression, p < 0.001; 0.219 for anxiety, p = 0.001; 0.262 for stress, p < 0.001). BSMAS scores demonstrated associations with poorer sleep quality (β = 0.292; p < 0.001) and IGDS9-SF scores (β = 0.157; p = 0.024) showed a significantly less robust association (p = 0.01 for comparing the two βs). These findings suggest that both severities of IGD and SMA associate with more psychological distress and poorer sleep quality, although the strengths of associations may differ
Effect of intravenous lignocaine infusion on bispectral index during spinal anaesthesia for caesarean section: A prospective randomised double-blind study
Get PDFBackground and Aims: Systemic lignocaine has been shown to have sedative effects. We designed
this randomised-double-blind, placebo-controlled study to evaluate the effect of intravenous
lignocaine on the bispectral index (BIS) during caesarean section under spinal anaesthesia.
Methods: 80 patients scheduled for elective caesarean section under spinal anaesthesia were
randomly allocated to 2 study groups. Group L received intravenous 1.5 mg/kg of lignocaine bolus,
15 minutes before spinal anaesthesia followed by an intravenous infusion 1.5 mg/kg/h for 60
minutes intravenously. The patients in the control group (C group) were given 0.9% sodium
chloride in a double-blind fashion. Spinal anaesthesia was performed with 10 mg of 0.5%
bupivacaine. The changes of Sao2, BIS and hemodynamic variables during caesarean section,
Apgar score of neonate and the incidence of adverse effects were recorded. Results: BIS values
were lower in the L group compared to C group (P ≤ 0.001). Comparison of mean arterial pressure
(MAP) changes during spinal anaesthesia and surgery reveal statistically significant difference
between two groups through repeated measure analysis (P ≤ 0.001), but comparision of heart rate
(HR) changes during spinal anaesthesia and surgery failed to reveal any statistically significant
difference between two groups. (P = 0.261). The Apgar scores did not reveal a significant
difference between the two groups at first and five minutes after delivery (P = 0.99). Conclusion:
Intravenous lignocaine infusion given with spinal anaesthesia in women undergoing elective
caesarean delivery providing lower BIS values without respiratory depression, in the absence of
foetal compromise
Molecular mechanisms and prevalence of colistin resistance of Klebsiella pneumoniae in the Middle East region: A review over the last 5 years
Get PDFThe increasing prevalence of multidrug-resistant (MDR) Klebsiella pneumoniae is a serious clinical and public health problem, and colistin is the last-resort treatment option for MDR infections. However, resistance to colistin has been increasingly reported in the world, such as the Middle East region, where antibiotics are used more in the human and agriculture industry. In this paper, we review the available data on the molecular mechanisms and prevalence of colistin resistance of K. pneumoniae in the Middle East over the last 5 years. To the best of our knowledge, 590 colistin-resistant K. pneumoniae isolates were reported from six countries, including Turkey (438), Iran (86), Saudi Arabia (24), United Arab Emirates (31), Kuwait (5), Israel (3) and Lebanon (3), between 2013 and 2018. However, there has been no reports about colistin resistance among K. pneumoniae isolates in Iraq, Yemen, Syria, Jordan, Palestine, Oman, Qatar, Bahrain and Cyprus. Moreover, it seems that mutations and insertion sequence transpositions in the mgrB gene were the most common colistin resistance mechanisms among K. pneumoniae in the Middle East region, which is similar to other parts of the world
