Qur'ān 2:183Arabic sense: الصيام, صيام | English sense: fasting
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ كُتِبَ عَلَيۡكُمُ ٱلصِّيَامُ كَمَا كُتِبَ عَلَى ٱلَّذِينَ مِن قَبۡلِكُمۡ لَعَلَّكُمۡ تَتَّقُونَ
You who believe, fasting is prescribed for you, as it was prescribed for those before you, so that you may be mindful of God
Qur'ān 2:187English sense: fasting | Arabic sense: الصيام, صيام
أُحِلَّ لَكُمۡ لَيۡلَةَ ٱلصِّيَامِ ٱلرَّفَثُ إِلَىٰ نِسَآئِكُمۡۚ هُنَّ لِبَاسࣱ لَّكُمۡ وَأَنتُمۡ لِبَاسࣱ لَّهُنَّۗ عَلِمَ ٱللَّهُ أَنَّكُمۡ كُنتُمۡ تَخۡتَانُونَ أَنفُسَكُمۡ فَتَابَ عَلَيۡكُمۡ وَعَفَا عَنكُمۡۖ فَٱلۡـَٰٔنَ بَٰشِرُوهُنَّ وَٱبۡتَغُواْ مَا كَتَبَ ٱللَّهُ لَكُمۡۚ وَكُلُواْ وَٱشۡرَبُواْ حَتَّىٰ يَتَبَيَّنَ لَكُمُ ٱلۡخَيۡطُ ٱلۡأَبۡيَضُ مِنَ ٱلۡخَيۡطِ ٱلۡأَسۡوَدِ مِنَ ٱلۡفَجۡرِۖ ثُمَّ أَتِمُّواْ ٱلصِّيَامَ إِلَى ٱلَّيۡلِۚ وَلَا تُبَٰشِرُوهُنَّ وَأَنتُمۡ عَٰكِفُونَ فِي ٱلۡمَسَٰجِدِۗ تِلۡكَ حُدُودُ ٱللَّهِ فَلَا تَقۡرَبُوهَاۗ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ ءَايَٰتِهِۦ لِلنَّاسِ لَعَلَّهُمۡ يَتَّقُونَ
You [believers] are permitted to lie with your wives during the night of the fast: they are [close] as garments to you, as you are to them. God was aware that you were betraying yourselves, so He turned to you in mercy and pardoned you: now you can lie with them- seek what God has ordained for you- eat and drink until the white thread of dawn becomes distinct from the black. Then fast until nightfall. Do not lie with them during the nights of your devotional retreat in the mosques: these are the bounds set by God, so do not go near them. In this way God makes His messages clear to people, that they may guard themselves against doing wrong

وَأَتِمُّواْ ٱلۡحَجَّ وَٱلۡعُمۡرَةَ لِلَّهِۚ فَإِنۡ أُحۡصِرۡتُمۡ فَمَا ٱسۡتَيۡسَرَ مِنَ ٱلۡهَدۡيِۖ وَلَا تَحۡلِقُواْ رُءُوسَكُمۡ حَتَّىٰ يَبۡلُغَ ٱلۡهَدۡيُ مَحِلَّهُۥۚ فَمَن كَانَ مِنكُم مَّرِيضًا أَوۡ بِهِۦٓ أَذࣰ ى مِّن رَّأۡسِهِۦ فَفِدۡيَةࣱ مِّن صِيَامٍ أَوۡ صَدَقَةٍ أَوۡ نُسُكࣲۚ فَإِذَآ أَمِنتُمۡ فَمَن تَمَتَّعَ بِٱلۡعُمۡرَةِ إِلَى ٱلۡحَجِّ فَمَا ٱسۡتَيۡسَرَ مِنَ ٱلۡهَدۡيِۚ فَمَن لَّمۡ يَجِدۡ فَصِيَامُ ثَلَٰثَةِ أَيَّامࣲ فِي ٱلۡحَجِّ وَسَبۡعَةٍ إِذَا رَجَعۡتُمۡۗ تِلۡكَ عَشَرَةࣱ كَامِلَةࣱۗ ذَٰلِكَ لِمَن لَّمۡ يَكُنۡ أَهۡلُهُۥ حَاضِرِي ٱلۡمَسۡجِدِ ٱلۡحَرَامِۚ وَٱتَّقُواْ ٱللَّهَ وَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ شَدِيدُ ٱلۡعِقَابِ
Complete the pilgrimages, major and minor, for the sake of God. If you are prevented [from doing so], then [send] whatever offering for sacrifice you can afford, and do not shave your headsuntil the offering has reached the place of sacrifice. If any of you is ill, or has an ailment of the scalp, he should compensate by fasting, or feeding the poor, or offering sacrifice. When you are in safety, anyone wishing to take a break between the minor pilgrimage and the major one must make whatever offering he can afford. If he lacks the means, he should fast for three days during the pilgrimage, and seven days on his return, making ten days in all. This applies to those whose household is not near the Sacred Mosque. Always be mindful of God, and be aware that He is stern in His retribution
Qur'ān 4:92English sense: fasting | Arabic sense: صيام
وَمَا كَانَ لِمُؤۡمِنٍ أَن يَقۡتُلَ مُؤۡمِنًا إِلَّا خَطَـࣰٔ اۚ وَمَن قَتَلَ مُؤۡمِنًا خَطَـࣰٔ ا فَتَحۡرِيرُ رَقَبَةࣲ مُّؤۡمِنَةࣲ وَدِيَةࣱ مُّسَلَّمَةٌ إِلَىٰٓ أَهۡلِهِۦٓ إِلَّآ أَن يَصَّدَّقُواْۚ فَإِن كَانَ مِن قَوۡمٍ عَدُوࣲّ لَّكُمۡ وَهُوَ مُؤۡمِنࣱ فَتَحۡرِيرُ رَقَبَةࣲ مُّؤۡمِنَةࣲۖ وَإِن كَانَ مِن قَوۡمِۭ بَيۡنَكُمۡ وَبَيۡنَهُم مِّيثَٰقࣱ فَدِيَةࣱ مُّسَلَّمَةٌ إِلَىٰٓ أَهۡلِهِۦ وَتَحۡرِيرُ رَقَبَةࣲ مُّؤۡمِنَةࣲۖ فَمَن لَّمۡ يَجِدۡ فَصِيَامُ شَهۡرَيۡنِ مُتَتَابِعَيۡنِ تَوۡبَةࣰ مِّنَ ٱللَّهِۗ وَكَانَ ٱللَّهُ عَلِيمًا حَكِيمࣰ ا
Never should a believer kill another believer, except by mistake. If anyone kills a believer by mistake he must free one Muslim slave and pay compensation to the victim’s relatives, unless they charitably forgo it; if the victim belonged to a people at war with you but is a believer, then the compensation is only to free a believing slave; if he belonged to a people with whom you have a treaty, then compensation should be handed over to his relatives, and a believing slave set free. Anyone who lacks the means to do this must fast for two consecutive months by way of repentance to God: God is all knowing, all wise

God does not take you [to task] for what is thoughtless in your oaths, only for your binding oaths: the atonement for breaking an oath is to feed ten poor people with food equivalent to what you would normally give your own families, or to clothe them, or to set free a slave- if a person cannot find the means, he should fast for three days. This is the atonement for breaking your oaths- keep your oaths. In this way God makes clear His revelations to you, so that you may be thankful

You who believe, do not kill game while you are in the state of consecration [for pilgrimage]. If someone does so intentionally the penalty is an offering of a domestic animal brought to the Kaba, equivalent- as judged by two just men among you- to the one he has killed; alternatively, he may atone by feeding the needy or by fasting an equivalent number of days, so that he may taste the full gravity of his deed. God forgives what is past, but if anyone re-offends, God will exact the penalty from him: God is mighty, and capable of exacting the penalty

726 to 750 of 832Risks and Benefits of Different Dietary Patterns in CKD.
Food has the potential to cause and exacerbate many lifestyle diseases. Or it can be used to prevent and treat illnesses like primary hypertension, the metabolic syndrome, and insulin resistance. In parallel, there is also a growing body of evidence of the role of diet in the treatment of kidney disease and its ensuing complications. Popular diets for this purpose have included low-carbohydrate diets, including the ketogenic diet, and higher carbohydrate diets like Mediterranean diets and other plant-based dietary patterns. Low-carbohydrate diets have not shown harm in patients with kidney disease and may benefit a select few. Mediterranean diets have an established record of cardioprotective benefits but also may be beneficial for the kidney. Intermittent fasting has benefits for metabolic health, but limited research exists on the risk or benefit for patients with kidney disease. Plant…

Walking Football During Ramadan Fasting for Cardiometabolic and Psychological Health Benefits to the Physically Challenged and Aged Populations.
Concurrent exercise and intermittent fasting regimens for long periods have been shown to enhance cardiometabolic health in healthy individuals. As exercise and fasting confer health benefits independently, we propose that Muslims who are fasting, especially those experiencing health and clinical challenges, continually engage in physical activity during the Ramadan month. In this opinion piece, we recommend walking football (WF) as the exercise of choice among Muslims who are fasting. WF can be played by any individual regardless of the level of fitness, skills, and age. WF has been shown to elicit cardiovascular and metabolic stress responses, which are suitable for populations with low fitness levels. Most importantly, WF has the inherent characteristics of being a fun team activity requiring social interactions among participants and, hence, likely to encourage long-term consistent a…

Impact of Ramadan diurnal intermittent fasting on the metabolic syndrome components in healthy, non-athletic Muslim people aged over 15 years: a systematic review and meta-analysis.
Studies on the impact of Ramadan diurnal intermittent fasting (RDIF) on the metabolic syndrome (MetS) components among healthy Muslims observing Ramadan month have yielded contradictory results. This comprehensive meta-analysis aimed to obtain a more stable estimate of the effect size of fasting during Ramadan on the MetS components, examine variability among studies, assess the generalisability of reported results and perform subgroup analyses for associated factors. We searched the CINAHL, Cochrane, EBSCOhost, Google Scholar, ProQuest Medical, PubMed/MEDLINE, ScienceDirect, Scopus and Web of Science databases for relevant studies published from 1950 to March 2019. The MetS components analysed were: waist circumference (WC), systolic blood pressure (SBP), fasting plasma/serum glucose (FG), TAG, and HDL-cholesterol. We identified eighty-five studies (4326 participants in total) that were…

Time-Restricted Feeding Reduces the Detrimental Effects of a High-Fat Diet, Possibly by Modulating the Circadian Rhythm of Hepatic Lipid Metabolism and Gut Microbiota.
Background: Time-restricted feeding, also known as intermittent fasting, can confer various beneficial effects, especially protecting against obesity, and related metabolic disorders, but little is known about the underlying mechanisms. Therefore, the present study aims to investigate the effects of time-restricted feeding on the circadian rhythm of gut microbiota and hepatic metabolism. Methods: Eight-week-old male Kunming mice received either a normal diet ad libitum, a high-fat diet ad libitum, or a high-fat diet restricted to an 8-h temporal window per day for an experimental period of 8 weeks. Weight gain and calorie intake were measured weekly. Serum metabolites, hepatic sections and lipid metabolites, gut microbiota, and the hepatic expression of Per1, Cry1, Bmal1, SIRT1, SREBP, and PPARα were measured at the end of the experimental period. The composition of gut microbiota and th…

Intermittent administration of a fasting-mimicking diet intervenes in diabetes progression, restores β cells and reconstructs gut microbiota in mice.
Fasting and especially intermittent fasting have been shown to be an effective intervention in many diseases, such as obesity and diabetes. The fasting-mimicking diet (FMD) has recently been found to ameliorate metabolic disorders. To investigate the effect of a new type of low-protein low-carbohydrate FMD on diabetes, we tested an FMD in db/db mice, a genetic model of type 2 diabetes. The diet was administered every other week for a total of 8 weeks. The intermittent FMD normalized blood glucose levels in db/db mice, with significant improvements in insulin sensitivity and β cell function. The FMD also reduced hepatic steatosis in the mice. Deterioration of pancreatic islets and the loss of β cells in the diabetic mice were prevented by the FMD. The expression of β cell progenitor marker Ngn3 was increased by the FMD. In addition, the FMD led to the reconstruction of gut microbiota. Int…

Mattson MP (2014)MEDLINE-indexed journal, not yet read by usDose-response : a publication of International Hormesis Society45 citations Challenging oneself intermittently to improve health.
Humans and their predecessors evolved in environments where they were challenged intermittently with: 1) food scarcity; 2) the need for aerobic fitness to catch/kill prey and avoid or repel attackers; and 3) exposure to biological toxins present in foodstuffs. Accordingly, cells and organ systems acquired and retained molecular signaling and metabolic pathways through which the environmental challenges enhanced the functionality and resilience of the cells and organisms. Within the past 60 years there has been a precipitous diminution of such challenges in modern societies because of the development of technologies that provide a continuous supply of energy-dense processed foods and that largely eliminate the need for physical exertion. As a consequence of the modern 'couch potato' lifestyle, signaling pathways that mediate beneficial effects of environmental challenges on health and dis…

Enriched environment ameliorates fear memory impairments induced by sleep deprivation via inhibiting PIEZO1/calpain/autophagy signaling pathway in the basal forebrain.
Aims: To verify the hypothesis that an enriched environment (EE) alleviates sleep deprivation-induced fear memory impairment by modulating the basal forebrain (BF) PIEZO1/calpain/autophagy pathway.
Methods: Eight-week-old male mice were housed in a closed, isolated environment (CE) or an EE, before 6-h total sleep deprivation. Changes in fear memory after sleep deprivation were observed using an inhibitory avoidance test. Alterations in BF PIEZO1/calpain/autophagy signaling were detected. The PIEZO1 agonist Yoda1 or inhibitor GsMTx4, the calpain inhibitor PD151746, and the autophagy inducer rapamycin or inhibitor 3-MA were injected into the bilateral BF to investigate the pathways involved in the memory-maintaining role of EE in sleep-deprived mice.
Results: Mice housed in EE performed better than CE mice in short- and long-term fear memory tests after sleep deprivation. Sleep deprivatio…

Melatonin ameliorates chronic sleep deprivation against memory encoding vulnerability: Involvement of synapse regulation via the mitochondrial-dependent redox homeostasis-induced autophagy inhibition.
Voluntary sleep curtailment is increasingly more rampant in modern society and compromises healthy cognition, including memory, to varying degrees. However, whether memory encoding is impaired after chronic sleep deprivation (CSD) and the underlying molecular mechanisms involved remain unclear. Here, using the mice, we tested the impact of CSD on the encoding abilities of social recognition-dependent memory and object recognition-dependent memory. We found that memory encoding was indeed vulnerable to CSD, while memory retrieval remained unaffected. The hippocampal neurons of mice with memory encoding deficits exhibited significant synapse damage and hyperactive autophagy, which dissipates during regular sleep cycles. This excessive autophagy appeared to be triggered by damage to mitochondrial DNA (mtDNA), resulting from oxidative stress within the mitochondria. The relief at the behavio…

Continuous Theta Burst Stimulation Inhibits Oxidative Stress-Induced Inflammation and Autophagy in Hippocampal Neurons by Activating Glutathione Synthesis Pathway, Improving Cognitive Impairment in Sleep-Deprived Mice.
Sleep deprivation (SD) has been reported to have a negative impact on cognitive function. Continuous theta burst stimulation (cTBS) shows certain effects in improving sleep and neurological diseases, and its molecular or cellular role in SD-induced cognition impairment still need further exploration. In this study, C57BL/6 mice were subjected to 48 h of SD and cTBS treatment, and cTBS treatment significantly improved SD-triggered impairment of spatial learning and memory abilities in mice. Additionally, cTBS reduced malondialdehyde levels, increased superoxide dismutase activities, and inhibited the production of inflammatory cytokines, alleviating oxidative stress and inflammation levels in hippocampal tissues of SD model mice. cTBS decreased LC3II/LC3I ratio, Beclin1 protein levels, and LC3B puncta intensity, and elevated p62 protein levels to suppress excessive autophagy in hippocampa…

Hyperactive neuronal autophagy depletes BDNF and impairs adult hippocampal neurogenesis in a corticosterone-induced mouse model of depression.
Background: Depression is a mental disorder that poses a serious threat to human health. Adult hippocampal neurogenesis (AHN) is closely associated with the efficacy of antidepressants. Chronic treatment with corticosterone (CORT), a well-validated pharmacological stressor, induces depressive-like behaviors and suppresses AHN in experimental animals. However, the possible mechanisms of chronic CORT action remain elusive. Methods: A chronic CORT treatment (0.1 mg/mL, drinking water for 4 weeks) was applied to prepare a mouse model of depression. Immunofluorescence was performed to analyze the hippocampal neurogenesis lineage, and immunoblotting, immunofluorescence, electron microscopy, and adeno-associated virus (AAV) expressing a pH-sensitive tandemly tagged light chain 3 (LC3) protein were used to analyze neuronal autophagy. AAV-hSyn-miR30-shRNA was used to knock down autophagy-related …

Comparative analysis of obesity prevalence, antioxidant and oxidant status in children with Down syndrome - a sibling-controlled study.
Introduction: Down syndrome (DS), a common genetic disorder, leads to various physical, cognitive, and developmental challenges. The supplementary copy of chromosome 21 introduces an abundance of genes, which potentially can influence metabolic irregularities. The aim of the study is to conduct a comprehensive comparative assessment of oxidative stress indicators (TAS, TOS, OSI), BMI, fasting glucose, and insulin levels, HOMA-IR among children and adolescents with DS in contrast to their non-DS siblings.
Material and methods: and the control group (CG) comprised 20 individuals, siblings of SG (mean age 15.92 years). Anthropometric measurements were conducted. TAS, TOS, fasting glucose, and insulin were assessed. BMI, BMI SDS, OSI and HOMA-IR were calculated.
Results: SG vs. CG: BMI - overweight (29,19% vs. 15%), obese (19,05% vs. 5%); TAS (1.92 mmol/l vs. 1.79 mmol/l (p = 0.0015)); TOS (…

Biosynthesis of gold nanoparticles using Nigella sativa and Curtobacterium proimmune K3 and evaluation of their anticancer activity.
In recent times, the development of functionalized nanoparticle methodology for biomedical applications has become a major challenge. In the present study, we prepared a novel gold nanoparticle (AuNP), named Curto-Cumin AuNP (CC-AuNP), using the biosynthetic process involving Nigella sativa (black cumin) seed extract and membrane vesicles isolated from the novel probiotic strain, Curtobacterium proimmune K3. Various spectrometric and microscopic analyses were performed to characterize the physicochemical properties of the nanoparticles. CC-AuNP exhibited significant cytotoxicity against human gastric adenocarcinoma (AGS) cells but not against normal cells. The toxic effects of the nanoparticles were associated with the excessive production of reactive oxygen species (ROS) in damaged mitochondria. Further, we investigated the molecular mechanisms underlying the cytotoxic effect of CC-AuNP…

Intergenerational Transmission of Diet-Induced Obesity, Metabolic Imbalance, and Osteoarthritis in Mice.
Objective: Obesity and osteoarthritis (OA) are 2 major public health issues affecting millions of people worldwide. Whereas parental obesity affects the predisposition to diseases such as cancer or diabetes in children, transgenerational influences on musculoskeletal conditions such as OA are poorly understood. This study was undertaken to assess the intergenerational effects of a parental/grandparental high-fat diet on the metabolic and skeletal phenotype, systemic inflammation, and predisposition to OA in 2 generations of offspring in mice.
Methods: Metabolic phenotype and predisposition to OA were investigated in the first and second (F1 and F2) generations of offspring (n = 10-16 mice per sex per diet) bred from mice fed a high-fat diet (HFD) or a low-fat control diet. OA was induced by destabilizing the medial meniscus. OA, synovitis, and adipose tissue inflammation were determined …

Thymoquinone Protects against Hyperlipidemia-Induced Cardiac Damage in Low-Density Lipoprotein Receptor-Deficient (LDL-R-/-) Mice via Its Anti-inflammatory and Antipyroptotic Effects.
Hyperlipidemia is a risk factor for cardiac damage and cardiovascular disease. Increasing evidence has shown that dyslipidemia-related cardiac damage is associated with lipid accumulation, oxidative stress, and inflammation. Thymoquinone (TQ) is the major constituent of Nigella sativa, commonly known as black seed or black cumin, and is globally used in folk (herbal) medicine for treating and preventing a number of diseases and conditions. Several studies have shown that TQ can protect against cardiac damage. This study is aimed at investigating the possible protective effects of TQ on hyperlipidemia-induced cardiac damage in low-density lipoprotein receptor-deficient (LDL-R-/-) mice. Eight-week-old male LDL-R-/- mice were randomly divided into normal diet (ND), high-fat diet (HFD), and HFD and TQ (HFD+TQ) groups and were fed the different diets for eight weeks.

Weight loss, improved physical performance, cognitive function, eating behavior, and metabolic profile in a 12-week ketogenic diet in obese adults.
The ketogenic diet (KD) is being increasingly promoted as a strategy to fight obesity. Although the KD is effective for weight loss and weight control, comprehensive determination of its relationship with biochemical, physiological and psychological changes is still largely unexplored. We hypothesized that a 12-week KD (12KD) would significantly affect body weight, physical performance, cognitive function, eating behaviors, the metabolic and hormonal profile in obese adults, although differently in men and women. In an uncontrolled intervention, 35 sedentary obese adults (13 men, 25 women), aged 37 ± 7 years with a BMI 36.1 ± 5.6 kg/m2 underwent a 12KD between March 2017 and June 2017 at the University of Primorska. The 12KD resulted in decreased appetite, significant weight loss of participants (-18 ± 9 kg men vs. -11 ± 3 kg women; P < .001), decreased emotional and external eating (P <…

Maternal insulin resistance multigenerationally impairs synaptic plasticity and memory via gametic mechanisms.
Metabolic diseases harm brain health and cognitive functions, but whether maternal metabolic unbalance may affect brain plasticity of next generations is still unclear. Here, we demonstrate that maternal high fat diet (HFD)-dependent insulin resistance multigenerationally impairs synaptic plasticity, learning and memory. HFD downregulates BDNF and insulin signaling in maternal tissues and epigenetically inhibits BDNF expression in both germline and hippocampus of progeny. Notably, exposure of the HFD offspring to novel enriched environment restores Bdnf epigenetic activation in the male germline and counteracts the transmission of cognitive impairment to the next generations. BDNF administration to HFD-fed mothers or preserved insulin sensitivity in HFD-fed p66Shc KO mice also prevents the intergenerational transmission of brain damage to the progeny. Collectively, our data suggest that …

Gut microbiota modulate neurobehavior through changes in brain insulin sensitivity and metabolism.
Obesity and diabetes in humans are associated with increased rates of anxiety and depression. To understand the role of the gut microbiome and brain insulin resistance in these disorders, we evaluated behaviors and insulin action in brain of mice with diet-induced obesity (DIO) with and without antibiotic treatment. We find that DIO mice have behaviors reflective of increased anxiety and depression. This is associated with decreased insulin signaling and increased inflammation in in the nucleus accumbens and amygdala. Treatment with oral metronidazole or vancomycin decreases inflammation, improves insulin signaling in the brain and reduces signs of anxiety and depression. These effects are associated with changes in the levels of tryptophan, GABA, BDNF, amino acids, and multiple acylcarnitines, and are transferable to germ-free mice by fecal transplant. Thus, changes in gut microbiota ca…

The cardioprotective effect of thymoquinone on ischemia-reperfusion injury in isolated rat heart via regulation of apoptosis and autophagy.
Thymoquinone (TQ), as the active constituents of black cumin (Nigella sativa) seed oil, has been reported to have potential protective effects on the cardiovascular system. This study aimed to investigate the effects and the underlying mechanisms of TQ on myocardial ischemia-reperfusion (I/R) injury in Langendorff-perfused rat hearts. Wister rat hearts were subjected to I/R and the experimental group were pretreated with TQ prior to I/R. Hemodynamic parameters, myocardial infarct size, cardiac marker enzymes, superoxide dismutase (SOD), malondialdehyde (MDA) content, and cardiomyocyte apoptosis were assayed. Compared with the untreated group, TQ preconditioning significantly improved cardiac function, reduced infarct size, decreased cardiac lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB) levels, suppressed enedoxidative stress, and apoptosis. In addition, TQ treatment promoted…

However, the effects of prebiotics, probiotics, and synbiotics on cognition and microglial activity in an obese-insulin resistant condition have not yet been investigated. We aimed to evaluate the effect of prebiotic (Xyloolidosaccharide), probiotic (Lactobacillus paracasei HII01), or synbiotics in male obese-insulin resistant rats induced by a HFD.
Methods: Male Wistar rats were fed with either a normal diet or a HFD for 12 weeks. At week 13, the rats in each dietary group were randomly divided into four subgroups including vehicle group, prebiotics group, probiotics group, and synbiotics group. Rats received their assigned intervention for an addition…

The discovery of RNAs (for example, messenger RNAs, non-coding RNAs) in sperm has opened the possibility that sperm may function by delivering additional paternal information aside from solely providing the DNA 1 . Increasing evidence now suggests that sperm small non-coding RNAs (sncRNAs) can mediate intergenerational transmission of paternally acquired phenotypes, including mental stress2,3 and metabolic disorders4-6. How sperm sncRNAs encode paternal information remains unclear, but the mechanism may involve RNA modifications. Here we show that deletion of a mouse tRNA methyltransferase, DNMT2, abolished sperm sncRNA-mediated transmission of high-fat-diet-induced metabolic disorders to offspring. Dnmt2 deletion prevented the elevation of RNA modifications (m5C, m2G) in sperm 30-40 nt RNA fractions that are induced by a high-fat diet. Also, Dnmt2 deletion altered the sperm small RNA ex…

Assessment of Ramadan Education and Knowledge Among Diabetic Patients.
Background: During Ramadan, Muslims fast from dawn until dusk for one lunar month every year. Most of the Muslim patients with diabetes are unaware of the potential complications that can occur while fasting, such as hypoglycemia. The aim of this study is to assess the the patient education level and patients' overall awareness of any possible complications that could occur while fasting during Ramadan and to determine how these patients deal with these complications.
Methods: We conducted a cross-sectional study and surveyed diabetic patients about their diabetes-related knowledge over a period of 4 months from the outpatient clinic at the Obesity, Endocrine, and Metabolism Center at King Fahad Medical City. Patients were included if they were ≥16 years and if they had been receiving treatment for at least 1 year before the study, irrespective of the medications used; patients were also…

Gut microbiota has a proven role in regulating multiple neuro-chemical pathways through the highly interconnected gut-brain axis. Oral bacteriotherapy thus has potential in the treatment of central nervous system-related pathologies, such as Alzheimer's disease (AD). Current AD treatments aim to prevent onset, delay progression and ameliorate symptoms. In this work, 3xTg-AD mice in the early stage of AD were treated with SLAB51 probiotic formulation, thereby affecting the composition of gut microbiota and its metabolites. This influenced plasma concentration of inflammatory cytokines and key metabolic hormones considered therapeutic targets in neurodegeneration. Treated mice showed partial restoration of two impaired neuronal proteolytic pathways (the ubiquitin proteasome system and autophagy). Their cognitive decline was decreased compared with controls, due to a reduction in brain dama…
