Insulin Resistance Vs Insulin Sensitivity When it comes to insulin and insulin sensitivity vs insulin resistance, you are always on a continuum of how insulin sensitive your are are and what tissues are most effective at absorbing glucose. This entry was posted in Misc, Nutrition and tagged carbohydrates, carbs, diabetes, insulin. Low blood sugar is common in many babies right after birth, as the baby’s body gets used to regulating its blood sugar level without help from the mother’s body. Infants of mothers who have diabetes may have more difficulty regulating their blood sugar. A healthcare provider uses a tiny blade (lancet) to take a drop of blood from your baby’s foot. Harjinder is losing water through perspiration while playing three-on-three basketball on a hot summer day. Harjinder forgot to bring a water bottle to the basketball court and has no water to drink.
This situation results in a decrease in the plasma (watery part) of the blood, so the solute (dissolved substances) concentration of the blood increases. Sensors (or receptors) in the hypothalamus, called osmoreceptors, sense the increased solute concentration, decreased blood volume, and decreased blood pressure. The hypothalamus sends messages to the posterior pituitary gland to increase the release of the hormone ADH.
An increased level of ADH causes the kidneys (kidney tubules) to retain (reabsorb) more water and release less in the urine. Reabsorbed water in the blood increases blood volume, increases blood pressure, and decreases solute concentration.
Information about the preceding three factors is fed back to the sensors in the hypothalamus.
Returning to the glucose example, if the pancreas were not able to decrease blood glucose after a meal because it could not produce insulin, the glucose level would remain high. Randall is losing water through perspiration while playing three-on-three basketball on a hot summer day. This situation results in a decrease in the plasma (watery part) of the blood, so the solute (dissolved substances) concentration of the blood increases and both the blood volume and the blood pressure decrease. Model describing hypothesized brain vascular reactivity abnormalities resulting in brain impairments. Schematic representation for potential pathways by which n-3 dietary deficiency may enhance vulnerability to cognitive and mood disorders. Omega-3 fatty acid deficiency, specifically an inadequate dietary intake of docosahexaenoic acid (DHA), is a recurring problem across these studies. The takeaway: Westernization of diets, specifically over consumption of fructose, is closely linked with developing metabolic syndrome and its accompanying cognitive impairment. AbstractSodium nitrite (NaNO2), a food color fixative and preservative, contributes to carcinogenesis. Biochemical analysisSerum glucose level was determined using the Biomerieux reagent kits [28]. A number of biochemical parameters were examined in the serum collected from each group and the results are summarized in table 1. The NaNO2 and other additives may react with amines of the foods in the stomach and produce nitrosamines and free radicals.

The finding is based on a study published in Neurology that recruited 141 people with a mean age of 63 who did not have diabetes. It’s also common in preemies born very early, because the organ that makes insulin (pancreas) is not fully developed. If a mother has diabetes, her baby is more likely to have temporary low blood sugar at birth. Given the following information about the hormone ADH (antidiuretic hormone) and its regulation of water volume in the body, summarize by drawing a negative feedback loop. In Unit B you will study the process of natural childbirth, which is dependent on positive feedback involving the hormone oxytocin. Using the information below, practise drawing a positive feedback loop to show how water regulation functions when the hormone ADH cannot be secreted.
In this example, positive feedback reinforces the loss of water in Randall’s body, not only from perspiring and drinking less, but also from excreting increased amounts of urine. Deficiencies in anti-inflammatory omega-3 fatty acids have also been shown to correlate with metabolic syndrome and cognitive decline.
For approval, comments need to be relevant to the article and free of profanities and personal attacks. In vivo evidence of hepato- and reno-protective effect of garlic oil against sodium nitrite-induced oxidative stress.
We investigated the protective role of garlic oil against NaNO2-induced abnormalities in metabolic biochemical parameters and oxidative status in male albino rats. Food and Drug Administration are commonly used to maintain or improve safety, the nutrient value, and the taste and texture of food [1].


The animals were kept under good ventilation and received a balanced diet and water ad libitum throughout the experimental period. Liver glycogen content was determined according to the method described by Van-Handle [29]. While rats fed on standard diet supplemented with garlic oil did not show any significant changes in the majority of the parameters examined, a significant increase in serum levels of glucose, bilirubin, urea and creatinine as well as the activity of the AST, ALT and ALP enzymes were observed in rats treated with NaNO2 for a period of three months. Such products may increase lipid peroxidation, which can be harmful to different organs including liver and kidney [37].
He received his MPh in Neuroscience and his PhD in Biochemistry from the University Claude Bernard Lyon-I, France. The subjects completed a series of memory tests and also had their blood sugar levels tested and scans of their brain taken. A healthcare provider may also give your baby supplemental sugar (glucose) through an IV (intravenous) line. If the baby is being fed through an IV, a healthcare provider may also lower the amount of glucose in the IV fluid. But babies need some sugar to grow and develop as they should.
The problem continues until the baby’s pancreas adjusts to his or her normal blood sugar level.
As the glucose was absorbed from the stomach and intestines, even higher blood glucose levels would result.
A simple path to a healthier life is to adopt a Paleo Diet, which is generally extremely low in fructose, and high in omega-3 fatty acids.
Omega-3 fatty acid deficiency during brain maturation reduces neuronal and behavioral plasticity in adulthood.
Obesity and metabolic syndrome and functional and structural brain impairments in adolescence.
NaNO2 treatment for a period of three months induced a significant increase in serum levels of glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), bilirubin, urea and creatinine as well as hepatic AST and ALT. Although many of the 3,000 these additives enhance our food supply, others are the subject of fierce controversy. Serum alanine aminotransfrase (ALT) and aspartate aminotransfrease (AST) activities were determined according to the method described by Reitman and Frankel [30], whereas alkaline phoasphatase (ALP) activity was estimated by Belfield method [31].
For comparison between different experimental rat groups, one way analysis of variance (ANOVA) was used followed by Tukey's test. On the other hand, these free radicals, known to cause oxidative stress, can be prevented or reduced by dietary natural antioxidants through their capacity to scavenge these products [38].
He completed his postdoctoral work at the International Agency for Research on Cancer (IARC). A body chemical (hormone) called insulin helps the body maintain a normal blood sugar level. If you experienced difficulty drawing the negative feedback loop, or if you do not understand the concept, consult with your teacher.

However, significant decrease was recorded in liver ALP activity, glycogen content, and renal urea and creatinine levels. The discovery that children at the age of nursery consume food containing great amounts of additives prompted the scientific community to oversee this issue.
Serum was separated from coagulant blood by centrifugation at 860g for 20 min, and then quickly frozen at -20°C for biochemical analysis. Total protein, bilirubin, urea and creatinine levels were determined using Diamond Diagnostic Kit as previously reported [32-33]. However, supplementation of NaNO2- intoxicated rats with garlic oil ameliorated the nitrite adverse effects as evidenced by a significant increase of serum total protein content, and a decrease of serum glucose, bilirubin, urea and creatinine levels, as well as the activity of AST, ALT and ALP enzymes (Table 1). Scientists explain that the relationship between blood sugar and memory may not be causal, however, the findings suggest that maintaining proper blood sugar levels through diet and exercise can have beneficial effects on cognitive health. If your baby has low or high blood sugar as a newborn, it does not mean that your baby is likely to grow up to have diabetes, either. In parallel, a significant increase in lipid peroxidation, and a decrease in glutathione content and catalase activity were observed in the liver and the kidney. Sodium nitrite (NaNO2) is present in vegetables and is routinely used as a color fixative and preservative for meats and fish [2].
Small pieces of liver and kidney tissues were separated, weighed, homogenized in ice cold water and stored at -20°C for subsequent measurements.
The product of lipid peroxidation, thiobarbituric acid reactive substances (TBARS), was determined as previously described [34].
The same parameters were examined in liver and kidney tissues, and the data are shown in table 2. The findings suggest nitrite-stimulation of gluconeogenesis [39], and glucose shift from tissue to blood or an impairment of glucose mobilization. So doctors will carefully watch your baby’s blood sugar level during his or her stay in the neonatal intensive care unit (NICU).


Drawing diagrams, feedback loops, and flow charts is often part of the open-response essay question on the Diploma Exam.

The hazardous effect of NaNO2 derives from the reaction of nitrites with amines to produce nitrosamines, and with amides to produce nitrosamides. Glutathione (GSH) content was estimated by the method of Prins and Loose [35], and the activity of catalase was determined by the method of Aebi [36]. In the NaNO2-treated rats, a statistically significant inhibition of hepatic glycogen and total protein contents, and the activity of the enzymes ALT and AST as well as the levels of renal urea, creatinine and total protein content (Table 2). Furthermore, nitroso-compounds can alter the antioxidant system causing disturbance in the metabolic processes leading to hyperglycemia [40]. If your baby's blood sugar is too high or too low, treatment will bring it back under control. The toxic effects of nitrates and nitrites are well documented in mammalians, including impairment of reproductive function [3], hepatotoxicity and methaemogobenemia [4], dysregulation of inflammatory responses and tissue injury [5], growth retardation [6], and endocrine disturbance [7].
The activity of hepatic ALP was significantly increased in the NaNO2-treated rats (Table 2).
However, serum glucose and liver glycogen levels were ameliorated upon garlic oil supplementation. Dr Ouhtit is an internationally respected scientist with awards for outstanding and innovative research.
However, administration of garlic oil to the NaNO2-intoxicated rats significantly restored these parameters in the liver and kidney organs (Table 2).Further, we assessed oxidative stress parameters and antioxidant activity in the liver and the kidney and the results are summarized in table 3. The hypoglycemic effect of garlic oil and its organo-sulfur compounds might be due to their ability to enhance insulin secretion [41, 42].Our results also indicate an inhibitory effect NaNO2 on the biosynthesis of protein, which was restored by garlic oil supplementation. Using F344 rat in a multiorgan carcinogenesis model, 0.3% NaNO2 given in the drinking water for 28 weeks increased the incidence of forestomach neoplasm in the post-initiation period [11].
The data indicate that TBARS concentration increased significantly, while GSH content, as well as catalase activity were decreased in both organs of NaNO2-intoxicated rats (Table 3).
These data suggest a stimulation of the thyroid and the adrenal glands by NaNO2 which can lead to a blockade in protein synthesis, fast breakdown, increased rate of free amino acids, and decreased protein turnover [43]. Scott Cancer Center, Louisiana State University Health Science Center, CSRB Building, Room# 748C, 533 Bolivar Street, New Orleans, LA 70112.
Thus, it cannot be precluded that NaNO2 has very weak carcinogenic potential, particularly in the squamous epithelium of the forestomach.
However, combination of garlic oil with NaNO2 reduced TBARS concentration and restored the levels of GSH as well as the activity of catalase (Table 3).
In addition, nitrite interactions results into nitric oxide release, which can inhibit total protein synthesis [44].
Moreover, in combination with other chemicals, NaNO2 has also been shown to form carcinogens or to enhance carcinogenesis. However, the increase in bilirubin concentration as well as the activity of AST, ALT and ALP enzymes in the serum of NaNO2-treated rats could be attributed to the toxic effect of nitroso-compounds, formed in the acidic environment of the stomach, in causing severe hepatic necrosis [45]. For instance, highly carcinogenic N-nitroso-compounds are produced when nitrite reacts with secondary amines and N-alkyl amides under acidic conditions in vitro [8, 12] and in vivo [13]. These abnormalities were prevented by supplementation of garlic oil, perhaps due to its role in stabilizing the cell membrane and protect the liver from free radical-mediated liver cell toxicity [46].In response to NaNO2 treatment, urea and creatinine were increased in the serum but decreased in the kidney, suggesting an impairment of kidney functions.
Other studies have demonstrated that treatment with NaNO2 in combination with phenolic compounds [11, 14] or ascorbic acid [15] strongly enhanced forestomach carcinogenesis in a rat two-stage carcinogenesis model.Recent trends in controlling and treating diseases tend to favor natural antioxidant compounds rather than synthetic ones [16]. These effects could also be attributed to the changes in the threshold of tubular re-absorption, renal blood flow and glomerular filtration rate [47].
The human diet, which contains large number of natural compounds, is essential in protecting the body against the development of diseases, and the garlic Allium sativum is one of the well known plant with remarkable anti-carcinogenic properties is [16, 17]. Garlic oil showed a clear improvement in kidney functions, perhaps due to the antioxidant properties of garlic in scavenging free radicals leading to reduced levels of nitric oxide and lipid peroxidation. Garlic, is a commonly worldwide used food, and its medical properties have been well recognized since the ancient times. Moreover, NaNO2-inhibited glutathione content and catalase enzyme activity in the liver and the kidney may be attributed to the observed induction of lipid peroxidation [48]. Garlic is known for its antibacterial [18], anticarcinogenic [19], hypolipidemic [20], hypoglycemic [21], antifungal [22], and anti-atherosclerotic [23] properties, and an antioxidant against free radicals [24, 25].Here, we investigated the role of garlic oil in preventing NaNO2-induced abnormalities in the biochemical parameters associated with the oxidative stress in male albino rats.
However, garlic improved the antioxidant mechanism due to the ability of Diallyl disulfide and Diallyl trisulfide present in garlic oil in modulating the oxidative stress and detoxifying enzyme system [49, 50, 51].In conclusion, from the results achieved it can be concluded that the administration of garlic has an extremely beneficial role in overcoming the occurred adverse effects of chronic ingestion of sodium nitrite, which is probably through its excellent antioxidant properties and highly nutritional values.
