“…In this study, pomegranate peel extract (PPE) treatment in diabetic rats for 4 weeks significantly reduced STZ-induced high blood glucose levels, and significantly elevated plasma insulin levels as compared to non-treated STZ diabetic rats. These findings suggest a significant antihyperglycemic effect of PPE in diabetic rats which are in agreement with the findings of study [29], where the researchers found that PPE led to significant reduction of blood glucose in STZ induced diabetes in rats. On the contrary, pomegranate peel did not exert significant hypoglycemic effect in alloxan induced diabetic rats as mentioned by researchers [33].…”

Purpose: Diabetes mellitus is a significant healthcare problem concern worldwide. It has different pathological effects on body tissues and organs especially on the major salivary glands. Pomegranate considers a native fruit that contains numerous polyphenolic antioxidant ingredients when compared to other fruits and vegetables. The aim of the current study was to explore the biological impact of Pomegranate Peel Extract on streptozotocin induced diabetes in submandibular salivary gland of albino rats. Methods: 30 male adult albino rats were separated into 3 groups: Group I (control), group II (diabetic group without any treatment), group III (diabetic group + Pomegranate Peel Extract). Diabetes induction was done by single intraperitoneal (i.p.) injection of streptozotocin. Plasma

“…Hypofunction or dysfunction of the salivary glands will have an impairment effect on the oral tissues [28]. This hypofunction may be happened due to drugs, or systemic disease such as diabetes [29]. Diabetes cause many oral complications such as periodontitis, hyposalivation, taste alteration and halitosis [30,31].…”

“…The most difficult problem to solve is the matrix effect from some soluble proteins, sugars, and fats [ 39 ], which can affect the detection of Pb and Cd. To eliminate matrix interference, the chemical matrix modifier, standard curves of different matrices, and their corresponding results were investigated.…”

A simple, rapid, sensitive, accurate, and automatic graphite furnace atomic absorption spectrometry (GFAAS) method for detecting Cd and Pb in cereals is presented. This method enables the simultaneous determination of Cd and Pb in cereals with a pre-treatment method of diluted acid extraction and a high-performance lead–cadmium composite hollow-cathode lamp (LCC-HCL), and it realizes automatic determination from sample weighing to result output through an automatic diluted acid extraction system. Under the optimization, Pb and Cd in cereals were simultaneously and automatically detected in up to 240 measurements in 8 h. The LOD and LOQ of this method were 0.012 and 0.040 mg·kg−1 for Pb, and 0.0014 and 0.0047 mg·kg−1 for Cd, respectively. The results of the four certified reference materials were satisfied; there was no significant difference compared with the ICP-MS method according to a t-test, and the RSDs were less than 5% for Cd and Pb. The recoveries of naturally contaminated samples compared with the ICP-MS method were favorable, with 80–110% in eight laboratories. The developed method is rapid, low-cost, and highly automated and may be a good choice for grain quality discrimination and rapid analysis of Cd and Pb in different institutions.

“…Heavy metals, aluminium and silicon in whole saliva and parotid saliva were obtained in Tables 5 and 6, respectively. Bovine Liver SRM 1577b, mussel tissue SRM 2976, poplar leaves GBW07604 and freeze-dried urine SRM 2670a were used in the assessments of RSD and R of the following elements in this order: Fe, Ti, Si, and some metals (Mo, Mn, Cr, Cu, Zn, and Al), respectively LOD and LOQ were calculated from the standard deviations (σ) of the response for 1% HNO 3 using criteria of three times the standard deviation and ten times the standard deviation, respectively [5,6]…”

Background and aims: Down's syndrome patients are suffering from such gastrointestinal and metabolic complications which affect their prolongation for survival and this could be attributed to the malnutrition system. To reduce the risk factors for mortality, the paper has focused on the assessment of the socioeconomic, clinical, physical, biophysiological, and biochemical characteristics of them which can be affected by the type of nutrition system, toxicity, and ecological footprint.Methods: Patients were males with trisomy 21 diagnosed by karyotype test and assessed by clinical examinations. The clinical observations, medical interventions, and oral diseases associated with DS have been defined and oral treatment is explored. Samples collected from different biofluids. The physicochemical analyses of the biomatrix samples were performed and these properties had compared to findings of healthy males and age-matched controls. In specific, trace elements which could be originated from environmental resources were assessed in saliva, blood, urine, and hair.Results: Duraphat application was proved effective for their oral treatment and saliva was the optimum biomarker for detecting malnutrition. The patients were hypersensitive to Cu while the Mn content in blood and hair was considered an expression to the degree of epileptic condition and chronic seizure development. The ecological footprint was 5.6 gha and carbon footprint was recognised in food poverty habits. These can be reduced by eating more plant-based proteins and fibre-rich foods with low saturated fats and sodium.Conclusions: The current findings provide an up-to-date reference for expected developmental outcomes in children with DS in terms of biophysicochemistry. The genetically sensitive intervention is affected by heredity factor and sensitivity to toxics. Down's syndrome is encouraged to live green-hipster life. Besides, doctors are recommended to order the physicochemical analyses for early detection of this special intervention.WHO Clinical Trial Registry: Study ID number: DRKS00014074 Title page of the study: Down's syndrome in children males – biochemical characterisations in different media using non-randomised trial and systematic study Website of Clinical Trial Registry: http://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00014074
