One highly studied mechanism implicated in the clinical benefits of calorie restriction involves sirtuins, a large and diverse family of enzymes that regulate gene expression. The first sirtuin, silent information regulator 2 (Sir2), was described in yeast. Sir2 is a class III histone deacetylase that uses the cofactor nicotinamide adenine dinucleotide (NAD+) in a catalytic reaction that releases nicotinamide (a feedback inhibitor) and O-acetyl ADP ribose (Imai et al. 2000; Marmorstein 2004; Sauve et al. 2006). It has been reported that increased Sir2 activity lengthens life span, and that calorie restriction increases Sir2 levels and does not promote longevity in SIR2 knockouts (Kaeberlein et al. 1999; Lin et al. 2000, 2004; Tissenbaum and Guarente 2001; Rogina and Helfand 2004). In mammals, calorie restriction increases the expression of Sirt1, the Sir2 mammalian ortholog, in various tissues, including brain. Resveratrol, a natural Sirt1 activator found in red wine, lengthens the life span of mice and prevents the age-related deterioration of their motor function (Cohen et al. 2004; Baur et al. 2006). Additionally, resveratrol stimulates AMP kinase activity in neurons (Dasgupta & Milbrandt, 2007), and more importantly, protects against kainic acid-induced seizures and oxidative stress in rats (Gupta et al., 2002).

While the relationships between seizure activity, oxidative stress and neuronal injury have yet to be clarified, previous studies have indicated that defects in antioxidant systems may contribute to seizure genesis and epileptogenesis (Cock, 2002; Patel, 2004; Liang & Patel, 2006; Shin et al, 2008). Earlier, the effects of a KD on mitochondrial ROS generation were discussed. Are there other mechanisms through which oxidative stress can be attenuated in epileptic brain?

The relevance of leptin to seizure susceptibility was recently highlighted by Erbayat-Altay and colleagues (2008) who demonstrated a significantly decreased threshold in leptin-deficient ob/ob mice to pentylenetetrazol-induced seizures. Indeed, leptin itself inhibits seizures induced by 4-aminopyridine and pentyelenetrazole-induced, possibly through blockade of AMPA receptor-mediated synaptic transmission (Xu et al., 2008). If the limiting of AMPA receptor-mediated transmission is a critical factor, it should be recalled this can also be accomplished by topiramate. With respect to the KD, the leptin signaling system is believed to contribute to slow weight gain associated with chronic treatment in both rodents and humans (Thio et al., 2006). KD-fed juvenile rodents had higher serum leptin levels and lower insulin levels than control rats fed a standard diet.

Alternatively, if simple calorie restriction is sufficient to prevent seizure activity in patients, why not decrease total caloric intake, and not bother with the high-fat KD? However, from yet another perspective, one could consider combining the KD and calorie restriction (as has been done in animal studies). In rats fed a calorie-restricted KD, Bough and colleagues (2003) demonstrated exhibited greater paired-pulse inhibition in the dentate gyrus, elevated maximal dentate activation threshold, and an absence of “spreading depression”-like events compared with ad libitum-fed controls. These results suggest that treatment with a calorie-restricted KD may produce both anticonvulsant and anti-epileptogenic effects.

Hal ini mempengaruhi asupan karbohidrat yang harus benar-benar dikurangi, dan menggantinya dengan lemak. Pengurangan karbohidrat menyebabkan tubuh Anda mengalami keadaan metabolisme yang disebut ketosis. Ketika hal itu terjadi, tubuh menjadi sangat efisien dalam membakar lemak sebagai energi. Hal ini juga membuat lemak menjadi keton (zat dari metabolisme lemak) di dalam hati, yang dapat menyediakan energi untuk otak.

In this article, we will take a look at some of the most popular diet tracking apps of 2019, in particular, those that can be used to assist with the ketogenic diet. When you decide to start with keto, it can be tough to determine what exactly you need to eat, how much you can eat, and what macronutrients you are ingesting on a daily basis. This is particularly true since most people have lost in touch with their hunger cues.

Resep Tumis Bunga Pepaya Kangkung Khas Manado ini kesukaan saya dan suami. Di awal-awal mencoba menbuat sendiri, saya tidak tahu caranya agar bunga pepaya tidak pahit. Saya pikir sama caranya dengan mengolah pare, agar tidak pahit diremas-remas dengan garam terlebih dahulu. Meskipun pahitnya berkurang, tapi bentuk bunga pepaya jadi tidak bagus. Ternyata ada cara yang …

Glucose restriction is believed to be a key mechanism of KD action. Calorie restriction in rodents reduced seizure susceptibility and the resultant low blood glucose levels correlated with inhibition of epileptogenesis in a genetic model of stimulus-induced epilepsy (Greene et al., 2001). Along related lines, Garriga-Canut et al. (2006) demonstrated that 2-deoxyglucose, which inhibits the glycolytic enzyme phosphoglucose isomerase, prevented seizure progression in the rat kindling model of temporal lobe epilepsy, and decreased the expression of brain-derived neurotrophic factor (BDNF) and its principal receptor, TrkB. More recently, Lian and colleagues (2007) demonstrated that fructose-1,6-bisphosphate (F-1,6-BP), a metabolite that shifts the metabolism of glucose from glycolysis to the pentose phosphate pathway, exhibits potent anticonvulsant activity in several rat models of acute seizures (i.e., pilocarpine, kainic acid, and pentylenetetrazole), and efficacy in these models exceeds that of 2-DG and KD treatment. Collectively, these emerging data indicate that the overall strategy of limiting glycolytic flux may be a powerful way of preventing acute seizures and perhaps epileptogenesis as well.
Informasi yg sangat bermanfaat untuk kita semua yg sedang mencari pola makan sehat yang juga mampu meregenerasi sel tubuh dan jauh dari penyakit dan sudah terbukti dari living proof keto warriors (orang yg berjuang menjalankan pola makan sehat ketogenic)..Dan kita harus open minded menerima informasi yang jauh berbeda dari info yangkita dapat selama ini….

Diet keto atau disebut juga dengan diet ketogenik berasal dari kata keton. Keton adalah senyawa kimia yang dihasilkan dari pemecahan lemak oleh hati. Biasanya, energi diambil dari glukosa yang bersumber dari karbohidrat. Namun, dikarenakan rendah karbohidrat maka tubuh akan kekurangan glukosa. Alhasil, secara otomatis tubuh menggunakan cadangan energi dari senyawa lainnya, yaitu lemak.
Another thing that Simply Fit Keto does in your body is that it boosts your metabolic rate. You will be able to lose much faster when your body is also on board with the weight loss plan. As your metabolism gets faster, all the food you are taking in will be broken down faster and you will also not face any digestive issues. This is a relief for people whose life has been made hell by slow metabolism.
