RESUMO

BACKGROUND: Exosome research continues to flourish. Subsequent knowledge surrounding indications, dose-response, safety, efficacy, and the ability to combine exosome treatment as a "skin primer"-for biostimulation modalities such as calcium hydroxylapatite (CaHA), platelet-rich plasma (PRP), and platelet-rich fibrin matrix (PRFM) is growing rapidly. The objective of this study was to develop safe, reproducible methods of improving topical exosome absorption to enhance the quality of skin either by themselves, or in combination with injectable CaHA. METHODS: Under IRB Approval (International Cell Surgical Society: ICSS-2022-007), 40 patients were enrolled in this study. Twenty patients underwent facial biostimulatory dermal infusion alone, to determine if this method allowed adequate exosome absorption. Five patients underwent facial biostimulatory infusion followed immediately by Dilute CaHA injection (1:1 dilution) to the face. Five patients underwent exosome biostimulatory dermal infusion followed immediately by hyperdilute CaHA (dilution 1:4) injection to the neck. Five patients underwent Facial Dilute CaHA injection (1:1 dilution) alone, without dermal infusion. Five patients underwent neck hyperdilute CaHA injection (1:4 dilution) alone, without dermal infusion. All patients had pretreatment Quantificare 3-D photo-documentation and skin analysis (Quantificare, France). In all patients, the skin was first cleansed with a gentle glycolic acid facial wash (Gregory MD). To induce a "homing inflammatory environment" for the exosomes, sea salt exfoliation was performed (SaltFacial®, SaltMed, Cardiff, CA). A nitric oxide-generating serum (N101 Pneuma Nitric Oxide, Austin, TX) was then applied to act as an enhanced vehicle for absorption. A 3 MHz ultrasound (SaltFacial®, SaltMed, Cardiff, CA) was then utilized to further deepen the absorption of the nitric oxide serum. A topical emulsion containing equal volumes (1.0 cc containing 1 million) of exosomes (Kimera Labs, Miramar, FL), 25 units of botulinum toxin (Xeomin, Merz Aesthetics, Raleigh, NC) and hyaluronic acid (Belatero, Merz Aesthetics, Raleigh, NC) was mixed via back-and-forth propulsion in a 3-cc syringe. When adequately mixed, the emulsion was then applied to the treatment areas. The cavitating ultrasound was then used to aid in the absorption of the emulsion. The patients were then treated with high-intensity LED therapy (SaltFacial®, SaltMed, Cardiff, CA), utilizing the collagen restoration preset program of combination red (660 nm) near-infrared (930 nm) wavelength for 20 min. Post-treatment Quantificare analysis was performed at 15 and 30 days after treatment. RESULTS: Without exception, all dermal infusion alone and CaHA injection alone patients showed an improvement in the tone, quality, and texture of their skin. Quantificare results showed consistent improvement in wrinkles, pores, skin evenness, improved vascularity, and a reduction in oiliness and unwanted pigment. When employed as a skin primer prior to injections (CaHA), enhanced and more rapid results were seen. CONCLUSIONS: Biostimulatory dermal infusion can be achieved utilizing topical placental mesenchymal stem cell-derived exosomes. These exosomes can be used alone, or mixed with ancillary ingredients such as botulinum toxin, hyaluronic acid dermal filler, and CaHA to customize and personalize treatments based upon individual patient needs. Topical absorption is enhanced with sea salt exfoliation, a topical nitric oxide-generating serum, and 3 MHz cavitating ultrasound. Post-absorption activity is enhanced with high-intensity LED treatment. The addition of CaHA injections after the topical exosome "priming of the skin" yielded enhanced skin quality faster than exosomes or CaHA alone.

RESUMO

The development of targeted drugs for the treatment of cancer remains an unmet medical need. This study was designed to investigate the mechanism underlying breast cancer cell growth suppression caused by fused isoselenazolium salts. The ability to suppress the proliferation of malignant and normal cells in vitro as well as the effect on NAD homeostasis (NAD+, NADH, and NMN levels), NAMPT inhibition and mitochondrial functionality were studied. The interactions of positively charged isoselenazolium salts with the negatively charged mitochondrial membrane model were assessed. Depending on the molecular structure, fused isoselenazolium salts display nanomolar to high micromolar cytotoxicities against MCF-7 and 4T1 breast tumor cell lines. The studied compounds altered NMN, NAD+, and NADH levels and the NAD+/NADH ratio. Mitochondrial functionality experiments showed that fused isoselenazolium salts inhibit pyruvate-dependent respiration but do not directly affect complex I of the electron transfer system. Moreover, the tested compounds induce an immediate dramatic increase in the production of reactive oxygen species. In addition, the isoselenazolothiazolium derivative selectively binds to cardiolipin in a liposomal model. Isoselenazolium salts may be a promising platform for the development of potent drug candidates for anticancer therapy that impact mitochondrial pyruvate-dependent metabolism in breast cancer cells.

RESUMO

BACKGROUND AND OBJECTIVES: To improve the iron status of school children through noon meals prepared using a multiple micronutrient-fortified salt. METHODS AND STUDY DESIGN: Children from a randomly selected school who consumed (intervention) and did not consume (reference) a noon meal prepared using a multiple micronutrient- fortified salt were studied over 1 year. A pre-post-test design for children aged 5-17years in reference (n=100) and intervention (n=128) groups was used. Levels of serum ferritin, soluble transferrin receptor (sTfR), alpha glycoprotein (AGP), and C-reactive protein (CRP) were assessed at baseline and at 1 year. In a subsample, urinary iodine was assessed. RESULTS: sTfR decreased in the intervention group (-0.80 mg/L) but increased in the reference group (0.47 mg/L) at 1 year (p=0.0001).Body iron stores (BIS) increased in the intervention group (0.09 mg/kg body weight) and decreased (-0.58 mg/kg body weight) in the reference group at 1 year (p=0.028).These findings indicate an increase in iron deficiency in the reference group and a decrease in the intervention group. However, no changes in serum ferritin and urinary iodine were observed in either group or between groups. CONCLUSIONS: Iron status can be improved in schoolchildren in Tamil Nadu by increasing the amount of micronutrients in the fortified salt used for preparing noon-time school meals.

RESUMO

A high-salt diet (HSD) is a major cause of many chronic and age-related defects such as myocardial hypertrophy, locomotor impairment and mortality. Exercise training can efficiently prevent and treat many chronic and age-related diseases. However, it remains unclear whether endurance exercise can resist HSD-induced impairment of climbing capacity and longevity in aging individuals. In our study, flies were given exercise training and fed a HSD from 1-week old to 5-weeks old. Overexpression or knockdown of salt and dFOXO were built by UAS/Gal4 system. The results showed that a HSD, salt gene overexpression and dFOXO knockdown significantly reduced climbing endurance, climbing index, survival, dFOXO expression and SOD activity level, and increased malondialdehyde level in aging flies. Inversely, in a HSD aging flies, endurance exercise and dFOXO overexpression significantly increased their climbing ability, lifespan and antioxidant capacity, but they did not significantly change the salt gene expression. Overall, current results indicated that a HSD accelerated the age-related decline of climbing capacity and mortality via upregulating salt expression and inhibiting the dFOXO/SOD pathway. Increased dFOXO/SOD pathway activity played a key role in mediating endurance exercise resistance to the low salt tolerance-induced impairment of climbing capacity and longevity in aging DrosophilaThis article has an associated First Person interview with the first author of the paper.

RESUMO

A high salt diet (HSD) is among the most important risk factors for many diseases. One mechanism by which HSD aggravates cerebral ischemic injury is independent of blood pressure changes. The direct role of HSD in inflammation after cerebral ischemia is unclear. In this research, after twenty-one days of being fed a high salt diet, permanent focal ischemia was induced in mice via operation. At 12 h and 1, 3 and 5 days postischemia, the effects of HSD on the lesion volume, microglia polarization, aldose reductase (AR) expression, and inflammatory processes were analyzed. We report that in mice, surplus dietary salt promotes inflammation and increases the activation of classical lipopolysaccharide (LPS)-induced microglia/macrophages (M1). This effect depends on the expression of the AR protein in activated microglia after permanent middle cerebral artery ligation (pMCAL) in HSD mice. The administration of either the AR inhibitor Epalrestat or a p38-neutralizing antibody blocked the polarization of microglia and alleviated stroke injury. In conclusion, HSD promotes polarization in pro-inflammatory M1 microglia by upregulating the expression of the AR protein via p38/MAPK, thereby exacerbating the development of ischemia stroke.

RESUMO

INTRODUCTION: This study examined changes in biomarkers of exposure (BoE) after 5 days of nicotine-salt pod system (NSPS) use, compared with continuation of usual-cigarette smoking and cigarette abstinence, among adult combustible cigarette smokers. AIMS AND METHODS: A randomized, open-label, parallel-cohort, confinement study of healthy adult smokers, naive to NSPS use, was conducted. Participants (N = 90) were randomized to six cohorts (n = 15 each): exclusive ad libitum use of NSPS (four flavors: Virginia Tobacco, Mint, Mango, Creme), continuation of usual-brand cigarette smoking, or cigarette abstinence. Total nicotine equivalents and BoE (NNN, NNAL, 3-HPMA, MHBMA, S-PMA, HMPMA, CEMA, 1-OHP, and COHb) were measured. RESULTS: Eight non-nicotine BoEs, measured in urine, were reduced by an aggregate of 85.0% in the pooled NSPS cohort; increased by 14.4% in the cigarette cohort (p < .001 for pooled NSPS vs. cigarette); and reduced by 85.3% in the abstinence cohort (p > .05; 99.6% relative reduction between pooled NSPS vs. abstinence). Similar changes in individual BoEs were also observed (p < .001 for each BoE between pooled NSPS vs. cigarettes; and abstinence vs. pooled NSPS; p > .05 for each BoE between pooled NSPS vs. abstinence). Blood COHb decreased by 71.8% in the pooled NSPS cohort and 69.1% in the abstinence cohort (p > .05) and increased by 13.3% in the cigarette cohort (p < .001). Mean total urine nicotine equivalents increased in the pooled NSPS and cigarette cohorts by 9% and 26%, respectively, and did not significantly differ (p > .05). CONCLUSION: Complete switching from cigarettes to NSPS produced significant reductions in key non-nicotine BoEs associated with cigarette smoking. IMPLICATIONS: The results of this study concorded with evidence that complete switching from combustible cigarettes to tobacco and nontobacco-flavored vapor products may reduce exposure to key carcinogens and other toxicants known to be associated with tobacco-related diseases. Future research is needed to assess the long-term health effects of NSPS use. These results should not be interpreted to mean that the use of NSPS is without any risk, particularly for nonusers of tobacco products.

RESUMO

The current study aimed to investigate the influence of four supplemental zinc salts (chelated: Zn glycine; non-chelated: Zn sulfate, Zn citrate, Zn gluconate) among different zinc concentrations (30-300 µM) on cell proliferation, oxidative stress, and energy depletion in intestinal porcine jejunum epithelial cells (IPEC-J2). Different zinc salts affected cell viability in a time- and dose-dependent manner, which was mainly dependent on the uptake of intracellular Zn2+. Intracellular Zn2+ of Zn sulfate has taken up almost twice as high as Zn glycine when cells were loaded with 100-200 µM zinc. After loading cells with 300 µM zinc, Zn glycine and Zn sulfate had a similar trend in accumulation of Zn2+. When the intracellular Zn2+ overloads, cells will gradually be damaged and subsequently die bearing biochemical features of necrosis or late apoptosis. Meanwhile, obviously, increased levels of intracellular ROS, mitochondrial ROS, MDA, and NO and decreased levels of GSH were observed. Excessive intracellular Zn2+ significantly decreased mitochondria membrane potential accompanied by an obvious loss of ATP and NAD+ levels. Overall, exposure to high doses of zinc salts caused cell damage, which was mainly dependent on the uptake of Zn2+. Zinc overload induced oxidative stress and energy depletion in IPEC-J2 cells, and the cell damage with non-chelated zinc addition was more serious than Zn glycine.

RESUMO

The polycystic ovary syndrome (PCOS) is the most frequent endocrinopathy in women in reproductive age with the so far undetermined causes of development. In the etiopathogenesis of PCOS, the role of insulin resistance is emphasised, which was an indication for the attempts at using chromium III salts (Cr) in augmenting pharmacotherapy applied in patients. The analysis of the usefulness and efficacy of this approach was the direct goal of this thesis. Animal tests confirmed the efficacy of chromium in maintaining the appropriate level of glycaemia and insulinaemia, normalisation of plasma concentrations of microelements and also a correlation between the Cr level, insulin and dehydroepiandrosterone (DHEA) was found. A decrease in the expression of 3ß-hydroxysteroid dehydrogenase and 17ß-hydroxysteroid dehydrogenase was identified in adipose tissue. Clinical studies, although sparse, show that the supplementation with chromium can improve BMI and the parameters evaluating the control of glycaemia and increase the chances for ovulation and regular menstruation. However, the small number and a variability in study protocols makes comparing them very difficult. A completely new subject that has not been yet studied is the possibility of using chromium in levelling mood disorders in patients with PCOS. Currently, there are still no sufficient proofs for introducing chromium as a standard in treating and preventing insulin resistance in patients with PCOS. However, this direction remains open, and treating insulin resistance is an important challenge in clinical practice.

RESUMO

OBJECTIVE: To compare the curative effect and the changes of serum electrolytes between oral rehydration salts (ORS) I and ORS III treatment in neurally mediated syncope children.
 Methods: The children with the symptom of unexplained syncope and pre-syncope were collected in Second Xiangya Hospital from May 2014 to May 2017. After head-up tilt test (HUTT), their serum electrolytes levels were examined. Children who were positive in the HUTT received ORS (ORS I or ORS III) and health education. Subjects were randomly divided into an ORS I group (n=27) and an ORS III group (n=49).
 Results: There was no statistical significance in sex, age, height, body mass, initial diagnosis and re-diagnosis interval between the 2 groups (P>0.05); the total efficiency after ORS III and ORS I treatment were 79.59% and 62.96%, respectively, with no statistical significance (χ2=2.483, P>0.05); the HUTT negative conversion rate after ORS III and ORS I treatment were 51.02% and 48.16%, respectively, with no statistical significance (χ2=0.058, P>0.05); before treatment, the serum sodium [(140.20±2.26) mmol/L vs (138.39±2.72) mmol/L; t=2.856, P<0.05] in the ORS III group was higher than that in the ORS I group, the serum phosphorus [(1.46±0.19) mmol/L vs (1.65±0.29) mmol/L; t=3.146, P<0.05] in the ORS III group was lower than that in the ORS I group; after treatment, the serum sodium [(140.31±2.01) mmol/L vs (138.88±2.08) mmol/L; t=2.692, P<0.05] and serum calcium [(2.31±0.09) mmol/L vs (2.24±0.11) mmol/L; t=2.696, P<0.05] in the ORS III group were higher than those in the ORS I group, the serum phosphorus [(1.45±0.16) mmol/L vs (1.61±0.25) mmol/L; t=3.128, P<0.05] in the ORS III group was lower than that in the ORS I group; after ORS III treatment, there was no statistical significance in serum electrolytes between HUTT positive group and HUTT negative group (P>0.05); after ORS I treatment, the serum calcium [(2.29±0.10) mmol/L vs (2.19±0.10) mmol/L; t=2.501, P<0.05] and serum phosphorus [(1.71±0.24) mmol/L vs (1.50±0.21) mmol/L; t=2.392, P<0.05] in HUTT positive group were higher than those in HUTT negative group. There was no statistical significance in serum sodium, potassium, magnesium, and chloride (P>0.05); there was no statistical significance in serum electrolytes between pre-treatment and post-treatment in the ORS I group and the ORS III group (P>0.05); there was no statistical significance in serum electrolytes between vasovagal syncope and postural orthostatic tachycardia syndrome in the ORS I group and the ORS III group before ORS treatment (P>0.05). 
 Conclusion: The ORS III and ORS I have the similar efficacy in the treatment of children with neurally mediated syncope. ORS III is easier to be accepted by children than ORS I, with better compliance.

RESUMO

Timely recanalization of infarct related artery along with effective myocardial cell reperfusion represents a major challenge in the management of STEMI. The reperfusion of coronary arteries can induce further cardiomyocyte death by generating oxidative stress, which itself can mediate myocardial damage through a number of different mechanisms. Based on experimental and clinical studies, interventions to treat reperfusion injury by antioxidants were considered to be an appropriate therapeutic option. We emphasize the hypothesis that glutathione sodium salt, a physiologic antioxidant, may be of value when administered to STEMI patients both at an early stage of myocardial reperfusion by primary angioplasty and for up to three days after the procedure, in addition to standard treatment.

RESUMO

Organic acids or their salts can be used as feed additives in aquaculture. This study was conducted to evaluate the use of a mixture of formic acid, propionic acid and calcium propionate compared with oxytetracycline (OTC). A total of 720 apparently healthy Oreochromis niloticus fingerlings with an average body weight of 28.8 ± 0.14 g (mean ± SE) were randomly divided into four equal groups (G1, G2, G3and G4). G1 was fed a basal diet with no additive as the control group, while G2 and G3 were fed a formic and propionic acid/salt mixture in 1 and 2 g/kg, respectively. G4 was fed OTC (0.5 g/kg). Each group was subdivided into tow subgroups A and B (30 fish/subgroup) in triplicate. The first subgroup was used to evaluate growth performance, hematology and body composition for 60 d. The second subgroup was used to examine immunity, gut microbiota and resistance to infection for 30 d. At the end of the feeding period (60 d), G3 had significant improvements in final body weight (FBW), weight gain (WG), specific growth rate (SGR) and food conversion ratio (FCR) compared with other groups. The total erythrocyte count, hemoglobin content, platelet count, hematocrit, mean corpuscular hemoglobin and total leukocyte count were significantly increased in G3 and G2 compared with G1 and G4. Mean corpuscular volum, lymphocyte and neutrophil percentages had the highest significant improvement in G3. There were no significant differences among the groups in mean corpuscular hemoglobin concentration and monocyte percentage. The protein and fat contents of the whole body were the highest in G3. The widest inhibition zones against Aeromonas sobria were at the 30, 40 and 50% concentrations of acidifiers, which were equivalent to OTC (30 µg). G3 showed the lowest total gastrointestinal bacterial counts, followed by G2. After 15 and 30 d, G3 had the highest serum killing, lysozyme and nitric oxide activities. Serum lysozyme activity and nitric oxide assay had no significant difference between G1 and G2 after 30 d. The lowest immune parameters were recorded in G4. After 30 d, the highest expression of interleukin-1ß and tumor necrosis factor-alpha in the liver and kidney were found in G3. The best protection against challenged Aeromonas sobria was in G3, followed by G2 and G4. Dietary supplementation with a combination of formic acid, propionic acid and calcium propionate improves the performance of Nile tilapia.

RESUMO

Irritable bowel syndrome (IBS) is a pathological condition characterized by heterogeneous etiology, pathogenesis, and clinical symptoms. These characteristics dictate the necessity of prescribing multiple medications for the treatment of IBS. Such compulsory polypharmacy inadvertently enhances the risk of adverse reactions to the treatment, increases its cost, and impairs compliance on the part of the patients. The objective of the present study was to evaluate the effectiveness of the administration of the clorine-bromine brine with the use of sinusoidal modulated current electrophoresis (SMC-phoresis) for the treatment of different forms of IBS. THE PATIENTS AND METHODS: We examined and treated 80 patients with different forms of IBS. The patients were divided into two equal groups comprised of 40 patients each. The patients of the study group were treated with the use of SMС-phoresis of the bromine-chlorine brine based at the «Varzi-yatchi¼ spa and health resort (the Udmurt Republic) making use of the sparing or stimulating techniques depending on the type of IBS. Each therapeutic course consisted of 10-12 sessions. The patients in the group of comparison received the standard pharmaceutical treatment for IBS (myotropic anti-spasmodics and lactulose). The emphasis was laid on the evaluation of dynamics of the intestinal motor function in different variants of IBS with the use of the EGS-4M apparatus based on the GSRS questionnaire (Gastrointestinal Symptom Rating Scale). Special attention was given to the interpretation of the main gastrointestinal syndromes and the evaluation of the quality of life of the patients in the course of the treatment and after its completion. RESULTS: Тhe main symptoms of IBS after a course of SMC-phoresis with the natural brine were significantly less pronounced compared to those in the patients managed by means of standard pharmacotherapy. Positive dynamics in the clinical picture of the disease had beneficial influence on the quality of life of the patients which approached that of the healthy subjects in the group of comparison. The results of colonography suggested the presence of various types of disturbances of motor function of the intestines. SMC-phoresis of the natural chlorine-bromine brine had a positive influence on dyskinesia associated with diarrhea and constipation associated with IBS, while the effect of the standard pharmaceutical treatment was unidirectional and significantly inferior to it in terms of efficiency. CONCLUSION: The use of complementary therapy can provide a better clinical outcome of IBS and to a greater extent improve the quality of life of the patients presenting with various forms of this pathology.

Síntese dos dados: Houve pouco avanço no uso dos sais de reidratação oral (SRO) nas últimas décadas apesar de ser amplamente divulgado por meio de diretrizes internacionais. Vários estudos vêm sendo feitos na tentativa de melhorar a eficácia do SRO. Hidratação venosa com solução salina isotônica, infundida de forma rápida, deve ser indicada em casos de desidratação grave. A nutrição deve ser assegurada logo após a resolução da desidratação e é primordial para a saúde intestinal e imunológica. Restrições alimentares usualmente não são benéficas e podem ser prejudiciais. As medicações sintomáticas têm indicação restrita e antibióticos são indicados em casos específicos, cólera e shiguelose moderada a grave. Conclusões: A hidratação e a nutrição continuam a ser as intervenções com melhor impacto sobre o curso da diarreia aguda.


Abstract Objectives: To describe the current recommendations on the best management of pediatric patients with acute diarrheal disease. Data source: PubMed, Scopus, Google Scholar. Data summary: There has been little progress in the use of oral rehydration salts (ORS) in recent decades, despite being widely reported by international guidelines. Several studies have been performed to improve the effectiveness of ORS. Intravenous hydration with isotonic saline solution, quickly infused, should be given in cases of severe dehydration. Nutrition should be ensured after the dehydration resolution, and is essential for intestinal and immune health. Dietary restrictions are usually not beneficial and may be harmful. Symptomatic medications have limited indication and antibiotics are indicated in specific cases, such as cholera and moderate to severe shigellosis. Conclusions: Hydration and nutrition are the interventions with the greatest impact on the course of acute diarrhea.

RESUMO

DDX3 belongs to DEAD box RNA helicase family and is involved in the progression of several types of cancer. In this work, we employed a High Throughput Virtual screening approach to identify bioactive compounds against DDX3 from ZINC natural database. Ketorolac salt was selected based on its binding free energy less than or equals to -5 Kcal/mol with reference to existing synthetic DDX3 inhibitors and strong hydrogen bond interactions as similar to crystallized DDX3 protein (2I4I). The anti-cancer activity of Ketorolac salt against DDX3 was tested using oral squamous cell carcinoma (OSCC) cell lines. This compound significantly down regulated the expression of DDX3 in human OSCC line (H357) and the half maximal growth inhibitory concentration (IC50) of Ketorolac salt in H357 cell line is 2.6 µM. Ketorolac salt also inhibited the ATP hydrolysis by directly interacting with DDX3. More importantly, we observed decreased number of neoplastic tongue lesions and reduced lesion severity in Ketorolac salt treated groups in a carcinogen induced tongue tumor mouse model. Taken together, our result demonstrates that Ketorolac salt is a newly discovered bioactive compound against DDX3 and this compound can be used as an ideal drug candidate to treat DDX3 associated oral cancer.

RESUMO

To explore whether oral rehydration salts (ORS) is effective in the treatment of children with vasovagal syncope (VVS). One hundred and sixty-six consecutive patients with recurrent syncope and positive head-up tilt testing (HUTT) were recruited, randomly divided to conventional therapy (health education and tilt training) plus ORS (with 500 ml of water) group (Group I, 87 patients) and conventional therapy group (Group II, 79 patients). Therapeutic effect was evaluated by changes of syncopal episode and reperformed HUTT response. At the end of 6-month follow-up, syncopal episode did not reoccur in 49 (56.3 %) patients, decreased in 34 (39.1 %) patients, and had no obvious change or increased in four (4.6 %) patients in Group I, and the results were 31 (39.2 %), 37 (46.8 %), and 11 (14 %) in Group II, respectively. The difference was significant (χ (2) = 7.074, P < 0.05). When HUTT was reperformed, 57 (65.5 %) and 28 (35.4 %) patients had negative response and 30 (34.5 %) and 51 (64.6 %) patients had positive response, respectively, in Group I and Group II. The difference was also significant (χ (2) = 13.808, P < 0.01). In Group I, the two aspects had no difference between vasodepressor type and mixed type; however, syncopal episode had a significant difference between children aged ≤12 and >12 years (χ (2) = 6.371, P < 0.05); there was no difference in reperformed HUTT response. ORS with 500 ml of water is an effective therapy for VVS. It can be recommended as one of non- pharmacological treatment measures in children with VVS.

RESUMO

Alkaline salt stress adversely affects rice growth, productivity and grain quality. However, the mechanism underlying this process remains elusive. We characterized here an alkaline tolerant mutant, alt1 in rice. Map-based cloning revealed that alt1 harbors a mutation in a chromatin remodeling ATPase gene. ALT1-RNAi transgenic plants under different genetic background mimicked the alt1 phenotype, exhibiting tolerance to alkaline stress in a transcript dosage-dependent manner. The predicted ALT1 protein belonged to the Ris1 subgroup of the Snf2 family and was localized in the nucleus, and transcription of ALT1 was transiently suppressed after alkaline treatment. Although the absorption of several metal ions maintained well in the mutant under alkaline stress, expression level of the genes involved in metal ions homeostasis was not altered in the alt1 mutant. Classification of differentially expressed abiotic stress related genes, as revealed by microarray analysis, found that the majority (50/78) were involved in ROS production, ROS scavenging, and DNA repair. This finding was further confirmed by that alt1 exhibited lower levels of H2O2 under alkaline stress and tolerance to methyl viologen treatment. Taken together, these results suggest that ALT1 negatively functions in alkaline tolerance mainly through the defense against oxidative damage, and provide a potential two-step strategy for improving the tolerance of rice plants to alkaline stress.

RESUMO

Orally administered iron salts (OAS) are widely used in the management of iron deficiency anemia and hypersensitivity reactions to OAS are not common. If an offending drug is the sole option or is significantly more effective than its alternatives, it can be readministered by desensitization. The oral desensitization protocols for iron published so far concern either desensitization that was completed only over a long period or did not attain the recommended therapeutic dose. We aimed to develop a more effective protocol. We report here on 2 patients who experienced hypersensitivity reactions to OAS. After confirming the diagnosis, both patients were desensitized to oral ferrous (II) glycine sulfate complex according to a 2-day desensitization protocol. A commercial suspension of oral ferrous glycine sulfate, which contains 4 mg of elemental iron in 1 ml, was preferred. We started with a dose as low as 0.1 ml from a 1/100 dilution (0.004 mg elemental iron) of the original suspension and reached the maximum effective dose in 2 days. Both patients were successfully desensitized and they went on to complete the 6-month iron treatment without any adverse effects. Although hypersensitvity reactions to iron are not common, there is no alternative for iron administration. Therefore, desensitization has to be the choice. This easy desensitization protocol seems to be a promising option.

RESUMO

BACKGROUND: Aluminium salts are common adjuvants in all established inactivated vaccines. They are necessary to activate the humoral immune system. In the 1990s a Swedish study on an acellular vaccination against pertussis was started. Until 2013, 745 of 760,000 children with pruritic subcutaneous nodules were identified. In 77 % of these children a contact allergy to aluminium could be proven. Contact allergy to aluminium induced by vaccines causes pruritic subcutaneous nodules at the vaccination site. During infections of the upper respiratory tract the pruritus often escalates with inflammatory, erythematous and urticarial plaques. CONCLUSIONS: The use of solutions containing aluminium salts for specific immunotherapy is contraindicated in the case of contact allergy to aluminium. Intramuscular injections of inactivated vaccines can be employed to avoid granuloma formation.

RESUMO

Recent studies have shown that high salt (HS) intake exacerbates experimental autoimmune encephalomyelitis and have raised the possibility that a HS diet may comprise a risk factor for autoimmune diseases in general. In this report, we have examined whether a HS diet regimen could exacerbate murine autoimmune thyroiditis, including spontaneous autoimmune thyroiditis (SAT) in non-obese diabetic (NOD.H2(h4)) mice, experimental autoimmune thyroiditis (EAT) in C57BL/6J mice challenged with thyroglobulin (Tg) and EAT in CBA/J mice challenged with the Tg peptide (2549-2560). The physiological impact of HS intake was confirmed by enhanced water consumption and suppressed aldosterone levels in all strains. However, the HS treatment failed to significantly affect the incidence and severity of SAT or EAT or Tg-specific immunoglobulin (Ig)G levels, relative to control mice maintained on a normal salt diet. In three experimental models, these data demonstrate that HS intake does not exacerbate autoimmune thyroiditis, indicating that a HS diet is not a risk factor for all autoimmune diseases.

RESUMO

Since its discovery in 1982, the global importance of Helicobacter pylori-induced disease, particularly in developing countries, remains high. The use of rodent models, particularly mice, and the unanticipated usefulness of the gerbil to study H. pylori pathogenesis have been used extensively to study the interactions of the host, the pathogen, and the environmental conditions influencing the outcome of persistent H. pylori infection. Dietary factors in humans are increasingly recognized as being important factors in modulating progression and severity of H. pylori-induced gastric cancer. Studies using rodent models to verify and help explain mechanisms whereby various dietary ingredients impact disease outcome should continue to be extremely productive.
