ABSTRACT
Background: Cucumber is one of the vegetables that are widely preserved by fermentation in brine. Vegetables such as cucumber are normally not washed in the commercial centers and this causes microbial growth during fermentation. At the beginning of the fermentation process, lactic acid bacteria, depending on the environmental conditions, begin to grow. The aim of this study was to compare the microbial, chemical, and sensorial characteristics of canned and bulk pickles
Methods: In this study, a random sampling was implemented from the pickles of three locations in Shiraz city as suppliers of pickles. The sensorial evaluation was also conducted by 60 members of the hospital staff. Data was collected through questionnaires. Sensorial evaluation was performed using a hedonic scale of nine points. For microbial assessment, Iran National Standards 2326 was used
Results: The results of the microbiological tests showed that bulk pickles were infected with mesophilic aerobic bacteria at 26.6%, aerobic thermophilic bacteria at 6.6%, and 43.3% by mold and yeast; while canned pickles [with license the Ministry of Health] were infected 13.3% by mesophilic aerobic bacteria. The average pH of the bulk samples based on the national standard was more than the maximum allowed level. The results of the sensorial evaluation of taste, texture, color, and overall acceptability showed that canned pickles had the most overall acceptance and texture acceptance points and bulk pickles had the most points of flavor and color acceptance
Conclusions: According to the findings, it seems that the use of herbs in bulk pickles is the main cause of increase in the microbial load and rated the taste, because fragrant fresh vegetables have a greater impact on the microbial load than dried vegetables
ABSTRACT
Background: Substance abuse has significant impact on nutritional status. Due to the increased malnutrition during drug use and withdrawal, this study aimed at assessing the anthropometric indices in individuals referring to drug treatment centers in Qom
Methods: In this descriptive-analytical study, 329 addicted individuals referring to addiction centers in Qom were randomly selected. A questionnaire was used with three parts including demographic characteristics, drug abuse history, and anthropometric indices including measurement of height, weight, waist circumference, arm circumference, and skinfold thickness in triceps and calf muscles
Results: The participants consisted of 328 men and only one woman, 29% of whom were in detoxification. The participants' mean age was 39.0 +/- 7.1 years. The first and most-frequently used drug was opium. All anthropometric indices were associated with the consumption of opium substances and drug use was associated significantly with some parameters. With the exception of skinfold thickness in the calf, all the indices were affected by the type of consumed substances. The opium addicts had a higher body mass index compared with other drug users
Conclusions: Due to the importance of nutrition status in drug abusers' health and their lack of self-care, careful monitoring and evaluation of dietary intake, as well as nutrition status can play important roles in the rehabilitation of these individuals and help to prevent from reappearance of these habits
ABSTRACT
Background: The present study was conducted to investigate the possible effects of L-carnitine and glutamine and their synergistic effects on male soccer athletes
Methods: 28 male soccer players [21.1 +/- 0.7 y] were enrolled in a randomized pre and post intervention, double-blind design. Before the intervention, their performances were assessed by Bruce protocol, and their body composition was measured with the body composition analyzer. Then, athletes were randomly allocated into four groups: 2 g L-glutamine, 2 g L-carnitine, 2 g L-carnitine + 2 g L-glutamine and placebo. Supplements were prescribed for 21 days and after three weeks, athletes' performances and body composition were re-evaluated
Results: The results showed that body weight, body fat percentage, lean muscle mass, and dietary intake made no significant changes in different groups of athletes. In between groups comparison, results did not significantly change in any performance indices. However, in L-carnitine supplement group, the results of pre and post intervention showed that the running distance and maximal oxygen uptake [VO2max] increased significantly while the subjective sense of fatigue decreased significantly
Conclusions: Based on our findings, a three-week prescription of separateor combined glutamine and L-carnitine, had no effects on body composition or dietary intake in soccer players. But, the athletes' energy intake was more than the one reported in other studies. Although further studies are required to assess these effects on athletic performance
ABSTRACT
No reflow is one major side effect that occurs in angioplasty and makes prognosis poor. This article reported the vital role of utilization of new thrombus aspiration catheters in treatment of this phenomenon to succeed in rescue angioplasty. [A 36-year-old man with failed response to streptokinase, 3.5 hrs after anterior STEMI was referred to cath-lab for rescue angioplasty. At angiography, LAD was totally occluded with thrombotic lesion. Because of high clot load, standard angioplasty failed to establish the flow aggravating hemodynamics, so we used the device to aspirate thrombus. This procedure was successful and normal coronary flow was restablished; chest pain terminated and blood pressure rose The presence of new thrombus aspiration catheters in cath-lab is an essential treatment device for success of primary and rescue angioplasty
ABSTRACT
Background and Purpose: Extracorporeal lithotripsy is one of the low risk treatments of renal stones. Its severe complication is hematoma and the most common complication is hematuria. Its cardiovascular effects include diastolic BP increase and ventricular arrhythmias, aggravation of heart failure and disturbance in cardiac pacemaker. The use of extracorporeal lithotripsy is nowadays on the rise in metropolitans. Prevention of life-threatening complications and the adoption of the best treatment procedure are essential for such patients
The Patient: A 48-year-old man underwent extracorporeal lithotripsy due to renal stone, and experienced chest pain two hours later. Diagnosed as the lower cardiac infarction, he received aspirin, streptokinase and heparin at the emergency department. Six hours later, he experienced severs hematuria and renal hematoma; anticoagulants was cut down; he was rescued by appropriate hydrotherapy, and drugs such as vasoconstrictives and aprotinin. He was discharged later
Conclusion: The occurrence of acute myocardial infarction due to extracorporeal lithotripsy must be considered; in order to prevent infarction, patients must be examined for cardiovascular conditions before and after extracorporeal lithotripsy
