The levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), progesterone and estradiol were measured in all the subjects before and after Ramadan. Measurements were carried out three days before the start of Ramadan, and one day afterwards. In this study, FSH levels significantly increased in the non-fasting group (P=0.01), and the level of Dehydroepiandrostenedione (DHEA) had a significant decrease during the time of study in both groups (P=0.001, P=0.006). In addition, serum levels of LH significantly increased in the non-fasting group after Ramadan (P=0.006), and estradiol significantly increased in both groups (P=0.008, P=0.004). Given the similar changes in the levels of DHEA, progesterone and estradiol in both study groups, it could be concluded that fasting has no effects on these parameters, and the changes in LH and FSH levels could be due to other contributing factors.","PeriodicalId":90593,"journal":{"name":"Journal of fasting and health","volume":"3 1","pages":"43-49"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68364173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, only one study has been carried out to explore the potential benefit of carbohydrate mouth rinse on exercise performance during Ramadan fasting. This single observation showed that a 10-km time trial performance was enhanced when performing mouth rinsing with either a carbohydrate or a placebo solution as compared with not performing mouth rinsing.

A systematic research was conducted in electronic databases in order to identify trials published between 1990 and 2014 concerning preoperative fasting, early resumption of oral intake and the effects of oral carbohydrate mixtures on gastric emptying and postoperative recovery. The publications were classified in terms of their evidence level, scientific validity and clinical relevance. The key recommendations are that children be encouraged to drink clear fluids within up to 2 hours before elective surgery (including Caesarean section) and all but one member of the guideline groups consider that tea or coffee, with milk added (up to about one fifth of the total volume), are still clear fluids .Furthermore, solid food consumption should be prohibited for up to 6 hours before elective surgery for children. However, patients should not have their operation cancelled or delayed only because they are chewing gums or sucking a boiled sweet immediately prior to the induction of anaesthesia. These recommendations also apply to those patients with obesity, gastro-oesophageal reflux and diabetes. There is insufficient evidence to support the routine use of antacids, metoclopramide or H2-receptor antagonists before elective surgery in non-obstetric patients. Infants should be fed before elective surgery. Breast milk is considered a safe option for up to 4 hours and other kinds of milk for up to 6 hours. The present review takes into account the safety and possible benefits of preoperative carbohydrates while offering advice on the postoperative resumption of oral intake.","PeriodicalId":90593,"journal":{"name":"Journal of fasting and health","volume":"2 1","pages":"131-135"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68363645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we intended to clarify the correlation between fasting and oral injections, bleeding following tooth extraction, and brushing to overcome common misconceptions which indicate the breach of religious disciplines under such circumstances.

Fasting for a short while before PET imaging is an example of such preparation. In this paper, we attempted to collect the studies evaluating the effects of fasting in the three sections of cardiac, brain and abdominal PET imaging. Conclusively, we found that the effects of fasting on PET imaging can be different depending on the type of PET scanning, radiotracer, patient’s diseases, fasting duration and in case of any additional dietary plans.

There is a direct relationship between fasting, abstaining from eating and drinking, and man’s health as well as ill-health. Therefore, through fasting the religious and medical issues are interwoven with each other; so that man can maintain his physical heath by performing a religious worship.Findings: Medical propositions which are based on experience can prove what would be harmful or urgent for body to take. In contrast, religious propositions relying on the meta-physical world are set for all people in every place at every time. Fasting is a religious term and in medicine, it is merely dealt with abstaining from eating and drinking. The concept of harmfulness means making a defect or disorder in the system of body, the recognition of which is the responsibility of medicine and the decision about which is within the responsibility of man. Conclusion: Medical science can determine the effects and consequences of thirst and hunger in the specific hours of the month of Ramadan. According to the religious perspective, it has been emphasized that fasting is for maintaining man’s health, and the conditions in which there is the probability of harmfulness for man’s health due to fasting, man shouldn’t fast. As a result, medical science can determine the interval of fasting.","PeriodicalId":90593,"journal":{"name":"Journal of fasting and health","volume":"2 1","pages":"158-161"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68364397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the cellular level it is possible to possess pathological starvation during ischemia and solid tumors. Blood provides many nutrients to our cells, and researchers provide these nutrients to cells in culture in the form of enriched culture medium plus serum from animal sources. In response to starvation, animals use hormonal cues to mobilize stored resources to provide nutrients to individual cells. Besides whole-body responses to nutrient deprivation, individual cells sense and react to lack of nutrients. At the cellular level, starvation triggers different responses such as cell cycle arrest and apoptosis. Stop cycling for proliferating cells is the primary response to nutrient deprivation. Under certain conditions, the cell reacts to nutrient deprivation by engaging the mitochondrial pathway of apoptosis. Thus, serum starvation is regarded as a procedure to prepare cells for an experiment in serum-free conditions such as induction cell cycle synchronization. Several researchers have used serum starvation as a tool to study molecular mechanisms involved in different cellular process, metabolic researches and evaluation of a drug effect.","PeriodicalId":90593,"journal":{"name":"Journal of fasting and health","volume":"2 1","pages":"147-150"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68364129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
