Rationale for the use of dexpanthenol drugs as part of the external therapy of dermatoses in children and adults

Impaired skin barrier plays a major role in the development of many skin diseases and conditions such as dry skin, sensitive skin, atopic dermatitis, contact dermatitis, etc. The topical therapy aims at not only suppressing the inflammatory response in the skin, but also at regenerating the destroyed protective epidermal lipid barrier in atopic dermatitis patients. Dexpanthenol was produced by synthesis in the middle of the last century and is a derivative of pantothenic acid. Topical dexpanthenol is well absorbed through the skin, where it is converted into pantothenic acid, a component of coenzyme A, and thus participates in the regulation of the synthesis of fatty acids and sphingolipids, components of the stratum corneum. Therefore, pantothenic acid is essential for the normal functioning of the epithelium. Topical dexpanthenol improves skin hydration due to its hygroscopic properties and ability to retain moisture. The hydrating effect is interrelated with its capacity to regenerate the epidermal barrier of the skin. Dexpanthenol also enhances the differentiation of corneocytes and lipid synthesis, stimulating the regeneration of the epidermis. Numerous studies show that the efficacy of dexpanthenol is comparable to the efficacy of glucocorticosteroids by a weak degree of activity. Dexpanthenol is the active ingredient of Pantoderm, which is available as cream and ointment. Pantoderm ointment and cream contain 5% dexpanthenol. The article presents its own clinical reports of the treatment of patients with atopic dermatitis and administration of the combination therapy. It may be concluded that the use of topical glucocorticosteroids combined with dexpanthenol can increase the effectiveness of therapy in patients with atopic dermatitis.

What Dietary Vitamins and Minerals Might Be Protective against Parkinson's Disease?

Dietary constituents may affect the progression of Parkinson's disease (PD). This study aimed to assess the contribution of dietary intake of vitamins and minerals to the severity, motor and non-motor symptoms, and risk of PD. In this case-control study, 120 patients with PD and 50 healthy participants participated. Dietary intake of vitamins and minerals was determined using a 147-item food frequency questionnaire. The severity of PD was determined by the Unified Parkinson's Disease Rating Scale (UPDRS). Patients with PD had lower intake of several vitamins and minerals including lycopene, thiamine, vitamin B6, vitamin B12, pantothenic acid, magnesium, zinc, manganese, selenium, chromium, and phosphorus, but had higher intake of α-tocopherol. High dietary intake of vitamin A, α-carotene, β-cryptoxanthin, vitamin C, and α-tocopherol were correlated with increased odds of PD. High intake of lycopene, thiamin, vitamin B6, pantothenic acid, magnesium, zinc, manganese, chromium, and phosphorous correlated with reduced odds of PD. The predictive power of α-tocopherol concerning the risk of PD was stronger relative to other vitamins. Dietary intake of pantothenic acid was negatively correlated with PD severity and symptoms of motor examination and complication. The severity and motor symptoms of PD were also negatively correlated with β-carotene, vitamin C, riboflavin, vitamin B6, and biotin intake. The UPDRS total score and motor symptoms in PD patients were negatively correlated with phosphorus, magnesium, zinc, manganese, and chromium, and strongly with potassium intake. The findings indicate that adequate dietary intake of vitamins and minerals may have a preventive effect on developing PD and progression of motor decline.

Does Religious Fasting Have a Protective Role against Metabolic Syndrome in Individuals Aged >50 Years?

The Christian Orthodox Church (COC) fasting is a periodic vegetarian-type diet lasting 180-200 days annually in which seafood and snails are allowed on all fasting days. Our aim was to investigate the effects of COC fasting on metabolic syndrome (MetS) in adults >50 years. One hundred seventy-six individuals participated in the study (mean age 59.7 ± 6.0 years). Eighty-nine had been following the COC fasting regime since their childhood and eighty-seven were non-fasters. Anthropometric measurements, blood samples, and nutrient intake data were collected at a scheduled appointment, during a non-fasting period. Fasters had significantly higher hip circumference (102 ± 8.5 vs. 98.8 ± 7.5 cm, p = 0.009), low-density lipoprotein (LDL) cholesterol (136 ± 73 vs. 115 ± 51 mg/dL, p = 0.033), and folic acid levels (6.0 ± 4.0 vs. 3.0 ± 1.2 ng/mL, p = 0.018), as well as lower systolic blood pressure (SBP) (131 ± 13 vs. 136 ± 14 mmHg, p = 0.045), diastolic blood pressure (DBP) (80 ± 8 vs. 83 ± 7 mmHg, p = 0.007), glucose (87 ± 16 vs. 93 ± 25 mg/dL, p = 0.039), and triglycerides (143 ± 94 vs. 175 ± 84 mg/dL, p = 0.040). Fasters had significantly less intake of calories (1493.65 ± 363.74 vs. 1614.65 ± 426.28 kcal, p = 0.044) and fat (81.17 ± 25.47 vs. 90.74 ± 24.75 g, p = 0.012), whereas they also consumed significantly less vitamin A-retinol, vitamin B2, vitamin B12, vitamin E, folic acid, pantothenic acid, calcium, phosphorus, zinc, and significantly more vitamin C (p < 0.005 for all comparisons). BP was significantly higher in non-fasters (44.8 vs. 22.5%, p = 0.002), whereas MetS was more frequently present in non-fasters vs. fasters, with a marginal level of significance (35.6 vs. 22.5%, p = 0.055). COC fasting may affect beneficially MetS prevalence in individuals >50 years, although future research is needed before reaching definite conclusions.

Camel milk peptides alleviate hyperglycemia by regulating gut microbiota and metabolites in type 2 diabetic mice

This study aimed to investigate the hypoglycemic effect of Camel milk peptides (CMPs) on Type 2 diabetes mellitus (T2DM) mice and reveal its related mechanism from the aspect of gut microbiota and metabolites. The administering CMPs significantly alleviated the weight loss, polydipsia and polyphagia, reduced fasting blood glucose (FBG), improved insulin resistance and sensitivity, and restored the level of serum hormones, lipopolysaccharide (LPS), lipid metabolic and tissue damage. Furthermore, CMPs intervention remarkably reversed gut microbiota dysbiosis in T2DM mice by reducing the relative abundance of Proteobacteria, Allobaculum, Clostridium, Shigella and the Firmicutes/Bacteroidetes ratio, while increasing the relative abundance of Bacteroidetes and Blautia. Metabolomic analysis identified 84 different metabolites between T2DM and CMPs-treated groups, participating in three pathways of Pantothenate and CoA biosynthesis, Phenylalanine metabolism and Linoleic acid metabolism. Ureidopropionic acid, pantothenic acid, hippuric acid, hydrocinnamic acid and linoleic acid were identified as key acidic metabolites closely related to hypoglycemic effect. Correlation analysis indicated that CMPs might have a hypoglycemic effect through their impact on gut microbiota, leading to variations in short-chain fatty acids (SCFAs), acidic metabolites and metabolic pathways. These findings suggest that CMPs could be a beneficial nutritional supplement for intervention T2DM.

Dietary habits and dietary nutrient intake in patients with age-related macular degeneration: A case-control study.

Age-related macular degeneration (AMD) is the leading cause of irreversible blindness among older adults in developed countries. Although many risk factors are known, the pathogenesis of AMD is still unclear. However, oxidative stress probably plays a vital role in the process of AMD. The increasing prevalence of AMD, risk of vision loss, limited treatment of dry form, expensive treatment of wet form, and decreased quality of life are factors that lead to considering modifiable risk factors of AMD, such as nutrition. This is the first study describing the relationship between dietary habits, dietary nutrient intake and AMD in the Czech Republic. In this research, a total of 93 cases with AMD and 58 controls without AMD and cataracts participated. All participants were ophthalmologically examined at the Clinic of Eye Treatments at the University Hospital Brno. Data were collected using a pre-tested self-report questionnaire in a face-to-face interview. Food consumption frequency was assessed by an 18-item semiquantitative food-frequency questionnaire (FFQ). Dietary nutrient intakes were calculated from a 24-hour recall. Patients with AMD compared with controls had significantly higher consumption of legumes and lower consumption of meat products, salt and salty products. In men, we found statistically significant differences in alcohol consumption. The case group consumed alcoholic beverages more frequently (median: 2 times a week) than the control group (median: 1-3 times a month). No differences in alcohol consumption were found in women. In comparison to the case group, the control group had a significantly higher dietary intake of energy (5,783.8 vs. 4,849.3 kJ/day; p = 0.002), proteins (65.3 vs. 52.3 g/day; p = 0.002), fats (57.6 vs. 49.4 g/day; p = 0.046), saturated fatty acids (21.7 vs. 18.9 g/day; p = 0.026), carbohydrates (150.4 vs. 127.1 g/day; p = 0.017), dietary fibre (13.2 vs. 11.3 g/day; p = 0.044), vitamin B2 (1.0 vs. 0.9 mg/day; p = 0.029), vitamin B3 (13.9 vs. 10.0 mg/day; p = 0.011), pantothenic acid (3.5 vs. 2.8 mg/day; p = 0.001), vitamin B6 (1.3 vs. 1.0 mg/day; p = 0.001), potassium (1,656.5 vs. 1,418.0 mg/day; p = 0.022), phosphorus (845.4 vs. 718.7 mg/day; p = 0.020), magnesium (176.5 vs. 143.0 mg/day; p = 0.012), copper (1.0 vs. 0.8 mg/day; p = 0.011), and zinc (7.1 vs. 6.1 mg/day; p = 0.012) counted from a 24-hour recall. According to FFQ, dietary habits in the patients with AMD and controls were similar. In men from the case group, we found statistically significant higher alcohol consumption. According to a 24-hour recall, the controls achieved recommended dietary intakes rather than cases. In comparison to the case group, the control group had a significantly higher dietary intake of energy, proteins, fats, saturated fatty acids, carbohydrates, dietary fibre, vitamin B2, vitamin B3, pantothenic acid, vitamin B6, potassium, phosphorus, magnesium, copper, and zinc.

A novel SLC5A6 homozygous variant in a family with multivitamin-dependent neurometabolic disorder: Phenotype expansion and long-term follow-up

The sodium-dependent multivitamin transporter (hSMVT) encoded by the SLC5A6 gene is required for the intestinal absorption of biotin, pantothenic acid and lipoate, three micronutrients essential for normal growth and development. Systemic deficiency of these elements, either occurring from nutritional causes or genetic defects, is associated with neurological disorders, growth delay, skin and hair changes, metabolic and immunological abnormalities. A few patients with biallelic variants of SLC5A6 have been reported, exhibiting a spectrum of neurological and systemic clinical features with variable severity. We describe three patients from a single family carrying a homozygous p.(Leu566Valfs*33) variant of SLC5A6 disrupting the frame of the C-terminal portion of the hSMVT. In these patients, we documented a severe disorder featuring developmental delay, sensory polyneuropathy, optic atrophy, recurrent infections, and repeated episodes of intestinal pseudo-obstruction. Two patients who did not receive multivitamin supplementation therapy died in early infancy. In a third patient, early supplementation of biotin and pantothenic acid stabilized the clinical picture changing the course of the disease. These findings extend genotype-phenotype correlations and show how a timely and lifelong multivitamin treatment may be crucial to reduce the risk of life-threatening events in patients with pathogenic variants of the SLC5A6 gene.

DETERMINATION OF FATTY ACIDS AND VITAMINS IN THE ACANTHOPHYLLUM PUNGENS PLANT COMPOSITION

This article presents the results of the quantitative determination of fatty acids and vitamins, contained in Acanthophyllum pungens plants, belonging to the Caryophyllaceae family growing in Khantagi, located near the city of Kentau, Turkestan region. As a result of gas chromatography of fatty acids, obtained as a result of studies of plant materials, it has been found that Acanthophyllum pungens contains 87% of unsaturated fatty acids, and 13% of saturated fatty acids. Saturated fatty acids: myristic, palmitic, stearic, pentadecanoic acids, while unsaturated fatty acids: palmitic, oleic, linoleic, and linolenic acids. As a result of quantitative analysis, it has turned out that oleic and linoleic acids are contained in large quantities, and the content of linolenic acid is much lower. It has been established that the plant Acanthophyllum pungens contains water-soluble B3-nicotinic acid, B5-pantothenic acid, B9-folic acid and vitamins A, C, E. It has also been found that the relatively high content of vitamin B5 (pantothenic acid), and the content of vitamins B6, B1, B2 and D are absent altogether. The phytochemical studies of the aboveground part of the Acanthophyllum pungens plant collected during the budding phase have been carried out in accordance with the methodological recommendations of the State Pharmacopoeia of the Republic of Kazakhstan. Using Clarus-600 gas chromatography, the amount of fatty acids (high-carbon acids) contained in the Acanthophyllum pungens plant has been determined. A qualitative analysis has been carried out by paper chromatography (PC) and gas-liquid chromatography (GC). A certain amount of vitamins and fatty acids of the Acanthophyllum pungens plant has been recommended for the first time.

#5462 METABOLIC PROFILING IN CHILDREN WITH END STAGE RENAL DISEASE ON PERITONEAL DIALYSIS: PRELIMINARY RESULTS OF AN ONGOING PRESPECTIVE STUDY

Abstract Background and Aims Peritoneal dialysis (PD) is the main renal replacement treatment for children and adolescents with end stage kidney disease (ESRD). Peritoneal fibrosis is a major complication in long-term PD patients. Aim of the present study is to record the metabolic "fingerprint" of children on PD and to investigate its correlation with PD history and dialysis adequacy as well as the emergence of potential biomarkers that could detect early or predict peritoneal dysfunction. Method Serum samples from 15 patients undergoing peritoneal dialysis were analyzed. Two targeted LC-MS methodologies were used for the determination of 107 metabolites in total. The obtained results were compared based on demographic and clinical parameters, both before and after the dialysis procedure. Serum samples were further divided into subgroups, based on PD duration, creatine clearance, sex, anuria. Reragding metabolic techologies used, all samples were analyzed by a hydrophilic interaction liquid chromatography coupled to mass spectrometry (HILIC-MS / MS) method previously developed and validated in our laboratory for the simultaneous determination of amino acids and their derivatives in biological fluids. Αlso, high flow analysis was carried out (LC-qTOF analysis – HPLC /MS). Results 8-OH-2-deoxyguanosine (8-hydroxy-2' -deoxyguanosine (8-OHdG) was the only metabolite found to differentiate between serum samples collected before and after PD (p&amp;lt;0.05). Grouping the samples by age groups (child, teen and late teen-young adult) we found out that succinate like lactate, N-acetyl-β-d-glucosaminidase (NAG), are potential markers for the quality of PD. Grouping the patients by number of peritonitis episodes (3 groups: no episodes, 1-2 episodes and &amp;gt;3 episodes) cytosine, riboflavin, glutamic acid, methylxantine and malate found to differentiate between the three groups (p &amp;lt;0.05). Regrading the creatinine cleranace, xylose, dCDP, HIAA, pyroglutamic, A CoA and methylxantine seems to be significan biomarkers. Grouping the patients based on the presence or absence of diuresis,HIAA, kynurenic,glucuronic and pantothenic acid found to differentiate between the two groups (p&amp;lt;0.05) Conclusion Based on the literatute the majority of the metabolites showed a statistically significant difference are involved in the inflammation process. Our results are the preliminary results of an ongoing prospective study. Limitation of the study, is the small sample of patients, which does not allow safe clinical interpretation. In any case, metabolomics seems to be a useful tool for the study and identification of biomarkers in patients with ESRD on PD.

Metabolomic differentiation of tumor core versus edge in glioma.

Gliomas exhibit high intratumor and interpatient heterogeneity. Recently, it has been shown that the microenvironment and phenotype differ significantly between the glioma core (inner) and edge (infiltrating) regions. This proof-of-concept study differentiates metabolic signatures associated with these regions, with the potential for prognosis and targeted therapy that could improve surgical outcomes. Paired glioma core and infiltrating edge samples were obtained from 27 patients after craniotomy. Liquid-liquid metabolite extraction was performed on the samples and metabolomic data were obtained via 2D liquid chromatography-mass spectrometry/mass spectrometry. To gauge the potential of metabolomics to identify clinically relevant predictors of survival from tumor core versus edge tissues, a boosted generalized linear machine learning model was used to predict metabolomic profiles associated with O6-methylguanine DNA methyltransferase (MGMT) promoter methylation. A panel of 66 (of 168) metabolites was found to significantly differ between glioma core and edge regions (p ≤ 0.05). Top metabolites with significantly different relative abundances included DL-alanine, creatine, cystathionine, nicotinamide, and D-pantothenic acid. Significant metabolic pathways identified by quantitative enrichment analysis included glycerophospholipid metabolism; butanoate metabolism; cysteine and methionine metabolism; glycine, serine, alanine, and threonine metabolism; purine metabolism; nicotinate and nicotinamide metabolism; and pantothenate and coenzyme A biosynthesis. The machine learning model using 4 key metabolites each within core and edge tissue specimens predicted MGMT promoter methylation status, with AUROCEdge = 0.960 and AUROCCore = 0.941. Top metabolites associated with MGMT status in the core samples included hydroxyhexanoycarnitine, spermine, succinic anhydride, and pantothenic acid, and in the edge samples metabolites included 5-cytidine monophosphate, pantothenic acid, itaconic acid, and uridine. Key metabolic differences are identified between core and edge tissue in glioma and, furthermore, demonstrate the potential for machine learning to provide insight into potential prognostic and therapeutic targets.

Exploring the effect of the Uyghur medicine Munziq Balgam on a collagen-induced arthritis rat model by UPLC-MS/MS-based metabolomics approach.

Munziq Balgam (MBm) is a classic preparation of a traditional Uyghur medicine used for many years to treat abnormal body fluid diseases. The formula, as an in-hospital preparation, has already been used in the Hospital of Xinjiang Traditional Uyghur Medicine to treat rheumatoid arthritis (RA) with significant clinical effects. This study intends to reveal the intervention effect of MBm on collagen-induced arthritis (CIA) rats, discover the potential biomarkers with efficacy, and explore the mechanisms of metabolic regulation by using metabolomics method. Sprague Dawley (SD) rats were randomly divided into five groups: blank group, CIA model group, Munziq Balgam nomal-dosage, Munziq Balgam high-dosage group and control group. Body weight, paw swelling, arthritis index, immune indices and histopathological experiments were carried out. Plasma from rats were detected by UPLC-MS/MS. Metabolomics of plasma was performed to analyze metabolic profiles, potential biomarkers, and metabolic pathways of MBm for CIA rats. The main metabolic result of Uyghur medicine MBm was compared with that of Zhuang medicine Longzuantongbi granules (LZTBG) to explore the characteristics of two ethnic medicines from different regions for RA. MBm could significantly alleviate symptoms of CIA rats by relieving arthritis symptoms on paw redness and swelling, inflammatory cell infiltration, synovial hyperplasia, pannus, cartilage and bone tissue destruction, as well as inhibiting the expression of IL-1β, IL-6, TNF-α, UA and ALP. Linoleic acid, alpha-linolenic acid, pantothenate and CoA biosynthesis, achidonic acid, gycerophospholipid, sphingolipid metabolism, primary bile acid biosynthesis, porphyrin and chlorophyll metabolism and fatty acid degradation served as the main nine pathways of the interventional effect of MBm on CIA rats. Twenty-three different metabolites were screened out and strongly associated with the indicator makes of RA. Eight potential efficacy-related biomarkers were finally discovered in metabolic pathway network (phosphatidylcholine, bilirubin, sphinganine 1-phosphate, phytosphingosine, SM (d18:1/16:0), pantothenic acid, l-palmitoylcarnitine, chenodeoxycholate). Three metabolites (chenodeoxycholate, hyodeoxycholic acid and O-palmitoleoylcarnitine) were changed in both the metabolic study of MBm and LZTBG intervention effects on CIA rats. Additionally, MBm and LZTBG shared the same 6 metabolic pathways including linoleic acid, alpha-linolenic acid, pantothenate and CoA biosynthesis, achidonic acid, gycerophospholipid, and primary bile acid biosynthesis. The study suggested that MBm may effectively alleviate RA by regulating inflammation, immunity-related pathways and multiple targets. Metabolomics analysis showed that MBm (Xinjiang, the north of China) and LZTBG (Guangxi, the south of China), two ethnic medicines from different regions in China, share common metabolites and pathways but also have distinct differences in their interventions for RA.

Dietary Intake of Micronutrients and Disease Severity in Patients with Amyotrophic Lateral Sclerosis.

Vitamins and essential metals have been studied as potential risk and prognostic factors in amyotrophic lateral sclerosis (ALS). This study aimed to evaluate the prevalence of inadequate micronutrient intake in ALS patients, comparing subgroups according to the disease severity. Data were obtained from the medical records of 69 individuals. Assessment of disease severity was determined by the revised ALS Functional Scale (ALSFRS-R), using the median as the cutoff. The prevalence of inadequate micronutrient intake was estimated using the Estimated Average Requirements (EAR) cut-point method. The prevalence of inadequate vitamin D, E, riboflavin, pyridoxine, folate, cobalamin, calcium, zinc, and magnesium intake was considered severe. Patients with lower ALSFRS-R scores had lower intakes of vitamin E (p < 0.001), niacin (p = 0.033), pantothenic acid (p = 0.037), pyridoxin (p = 0.008), folate (p = 0.009) and selenium (p = 0.001). Therefore, ALS patients should be monitored regarding dietary intake of micronutrients essential in neurological processes.

Dexpanthenol protects against lipopolysaccharide-induced acute kidney injury by restoring AQP-2 levels via regulating SIRT-1 signaling pathway.

Acute kidney injury (AKI) is a serious pathology, causing dysfunction of urination and concentration due to damage to kidneys, resulting with blood pressure dysregulation and increased toxic metabolites. Dexpanthenol (DEX), a pantothenic acid analog, has anti-inflammatory and anti-apoptotic properties in various tissues. This study aimed to investigate the protective effects of DEX in systemic inflammation induced AKI. Thirty-two female rats were randomly assigned as control, lipopolysaccharide (LPS), LPS+DEX and DEX groups. LPS (5 mg/kg, single dose on 3rd day, 6 hours before sacrification) and DEX (500 mg/kg/d for 3 days) were administered intraperitoneally. After sacrification, blood samples and kidney tissues were collected. Hematoxylin-eosin, caspase-3 (Cas-3) and tumor necrosis factor alpha (TNF-α) staining were performed on kidney tissues. Total oxidant status (TOS) and total antioxidant status levels were measured with spectrophotometric method. Aquaporin-2 (AQP-2), silent information regulator gene-1 (SIRT1) and interleukin-6 (IL-6) gene expressions were detected with qRT-PCR. In the histopathological analysis, it was observed that DEX ameliorated histopathological changes. In the LPS group, there was an increase in blood urea nitrogen, creatinine, urea, TOS, oxidative stress index, IL-6, Cas-3, and TNF-α levels compared to the control group, while AQP-2 and SIRT1 levels were decreased. However, treatment with DEX reversed all these changes. In conclusion, DEX was found to be effective in preventing inflammation, oxidative stress, and apoptosis in the kidney through the SIRT1 signaling pathway. Thus, the protective properties of DEX suggest that it may be a potential therapeutic agent for kidney pathologies.

Potential of algae-derived alginate oligosaccharides and β-glucan to counter inflammation in adult zebrafish intestine.

Alginate oligosaccharides (AOS) are natural bioactive compounds with anti-inflammatory properties. We performed a feeding trial employing a zebrafish (Danio rerio) model of soybean-induced intestinal inflammation. Five groups of fish were fed different diets: a control (CT) diet, a soybean meal (SBM) diet, a soybean meal+β-glucan (BG) diet and 2 soybean meal+AOS diets (alginate products differing in the content of low molecular weight fractions - AL, with 31% < 3kDa and AH, with 3% < 3kDa). We analyzed the intestinal transcriptomic and plasma metabolomic profiles of the study groups. In addition, we assessed the expression of inflammatory marker genes and histological alterations in the intestine. Dietary algal β-(1, 3)-glucan and AOS were able to bring the expression of certain inflammatory genes altered by dietary SBM to a level similar to that in the control group. Intestinal transcriptomic analysis indicated that dietary SBM changed the expression of genes linked to inflammation, endoplasmic reticulum, reproduction and cell motility. The AL diet suppressed the expression of genes related to complement activation, inflammatory and humoral response, which can likely have an inflammation alleviation effect. On the other hand, the AH diet reduced the expression of genes, causing an enrichment of negative regulation of immune system process. The BG diet suppressed several immune genes linked to the endopeptidase activity and proteolysis. The plasma metabolomic profile further revealed that dietary SBM can alter inflammation-linked metabolites such as itaconic acid, taurochenodeoxycholic acid and enriched the arginine biosynthesis pathway. The diet AL helped in elevating one of the short chain fatty acids, namely 2-hydroxybutyric acid while the BG diet increased the abundance of a vitamin, pantothenic acid. Histological evaluation revealed the advantage of the AL diet: it increased the goblet cell number and length of villi of the intestinal mucosa. Overall, our results indicate that dietary AOS with an appropriate amount of < 3kDa can stall the inflammatory responses in zebrafish.

Beneficial effects of Sai Sure as a dietary supplement in school children

Breakfast is the most important component of the day. A healthy breakfast provides good concentration to the children to be attentive in class. It also provides energy to play well. Breakfast provides most of the essential nutrients so that the children do not get nutritional deficiencies. According to the Government of Karnataka, about 2.1 lakh children which are 6.4% of the total children in government schools do not get breakfast at their homes. For these students, milk provided by the government is the only source of nutrition at the beginning of the day. Though milk consists of all essential nutrients in it, some of the vitamins are present in small amounts like niacin, pantothenic acid, vitamin B6, vitamin C, and folate. Hence, there is a requirement for some additional nutritious supplements to provide complete nutrition to the children.

Effects of container type and size on thermal processing characteristics and B-vitamin retention of canned cat food.

Rigid cans were the traditional container for canned cat foods, but semi-rigid trays/tubs and flexible pouches are popular options as well. Despite this, little is published on the effects of canned cat food container characteristics on thermal processing and retention of B-vitamins. Therefore, the objective was to evaluate the effects of container size and type on thermal processing and B-vitamin retention. Treatments were arranged in a factorial with two container sizes [small (85-99 g) and medium (156-198 g)] and three container types (flexible, semi-rigid, and rigid). A canned cat food formula was prepared, filled, and sealed into containers before retort processing to a heating cycle target lethality of 8 min. Internal retort and container temperatures were used to calculate accumulated lethality. Thiamin, riboflavin, niacin, pantothenic acid, pyridoxine, biotin, folic acid, cobalamin, and moisture contents were analyzed in pre- and post-retort samples by commercial laboratories. Thermal processing metrics were analyzed (SAS v. 9.4; SAS Institute, Cary, NC) with the fixed effects of container size, container type, and their interaction. Dry matter basis B-vitamin contents were analyzed with container size, container type, processing stage, and all two-way and three-way interactions as fixed effects. Means were separated using Fisher's LSD at a P-value < 0.05. Total accumulated lethality was greater (P < 0.05) for semi-rigid and flexible containers (average 14.99 min) than for rigid containers (12.86 min). The greater processing of semi-rigid and flexible containers was likely influenced by required retort settings. Thiamin and riboflavin contents decreased (P < 0.05) by 30.4 and 18.3%, respectively, due to retort processing. Niacin, biotin, and cobalamin were not affected (P > 0.05) by processing. Processing increased (P < 0.05) pantothenic acid (9.1%), pyridoxine (22.6%), and folic acid (22.6%). This was likely caused by sampling or analytical variation. No interaction involving processing stage was significant for any B-vitamin (P > 0.05). B-vitamin retention was not influenced by differences in thermal processing caused by the packaging treatments. Thiamin and riboflavin were the only B-vitamins meaningfully impacted by processing and retention was not improved by any container characteristic.

Untargeted metabolomics reveal sex-specific and non-specific redox-modulating metabolites in kidneys following binge drinking

Graphical abstract Abstract Binge drinking is a growing health concern among all age groups. The ability of individuals to handle ethanol in their systems differs not due to differences in enzyme expression but also due to other factors. Vital organs including brain, liver, heart, and kidneys are at high risk following repeated exposure to high concentrations of ethanol from binge drinking. The impact of chronic binge drinking on kidneys is not well studied. Using a mouse model of chronic binge drinking, we have identified major metabolic alterations that could set the stage for detrimental effects in the kidneys of male and female mice. We have deciphered that even though there are pathway overlaps, the different sexes exhibited unique and divergent metabolic pathway dysregulations as per the metabolite panels following binge drinking. We have reported that binge drinking could negatively influence renal redox homeostasis in both sexes through the regulation of different metabolite clusters. In male mice by downregulation of pantothenic acid and riboflavin synthesis, and in female mice by upregulation of α-aminoadipic acid and formyl kynurenine level. Interestingly, the uric acid biosynthesis pathway has been upregulated independent of the sex-specific effects, portraying the significance of uric acid as a potential marker for binge drinking-induced injury in both sexes. Thus, by altering renal metabolome, binge drinking sets the stage for renal damage by disturbing renal redox balance. Our data has high translational potential and will aid in finding ideal therapeutics in a sex-specific manner for subjects exposed to binge drinking- induced renal injury.

A Non-targeted Metabolomics Reveals Therapeutical Effect and Mechanism of Sanmiao Pill on Adjuvant-induced Arthritis Rats.

Rheumatoid arthritis (RA) is an increasingly serious disease worldwide that can damage the joints and bones of sufferers. Sanmiao Pill (SMP), a classical traditional Chinese medicine (TCM) prescription, has been used for effective treatments for RA in the clinic. To comprehensively illuminate the therapeutic mechanism of SMP in the treatment of RA, the effects of SMP on biomarkers and metabolic pathways in rats with adjuvant-induced arthritis (AIA) were examined. > Methods: Sprague Dawley rats were randomly divided into two control (CC, Control) groups, two model (MM, Model) groups, a methotrexate group (MTX, 7.6 mg/kg body weight per week), and two SMP groups (San-L, 28.7 mg/kg body weight per day and San-H, 57.4 mg/kg body weight per day). Rats' body weight, paw swelling, arthritis scores, biochemical parameters, histopathology, and so on were used to evaluate the success of the model and the therapeutic effects of SMP. The metabolic techniques were used to characterize the metabolic profile and biomarkers of the serum and urine samples of rats to reveal the metabolic changes that occurred after SMP treatment. > Results: After 21 days of treatment, SMP improved weight gain, reduced the severity of paw swelling, lowered the levels of biochemical indicators (CCP-Ab, IL-6, TNF-α, RF), decreased destruction of articular cartilage and bone erosion, and protected the affected joints.Additionally, 17 and 19 potential biomarkers associated with RA were identified in the serum and urine, respectively. SMP significantly reversed 14 potential biomarkers, such as arachidonic acid, lysoPC(20:4(5Z,8Z,11Z,14Z)), L-tryptophan, 9-cis-Retinoic acid, hippuric acid, pyridoxine, and pantothenic acid. These metabolites are associated with arachidonic acid metabolism, glycerophospholipid catabolism, tryptophan metabolism, phenylalanine metabolism, vitamin B6 metabolism, etc. > Conclusion: These results indicated that RA-related biomarkers reflected the metabolic profile of AIA rats. Meanwhile, SMP could effectively treat RA mainly by reducing inflammation and regulating abnormal lipid metabolic pathways and amino acid metabolisms.

The whole change of the new standard was major. Comparing with GB 10767-2021, there were 8 essential compositions in commercial products with 100% compliance rate and 9 with more than 95% compliance rate, the discordance rate of pantothenic acid, folic acid, vitamin C and Vitamin D was more than 20%, Vitamin D has the highest discordance rate 97.10%. Although the revision of the essential composition requirements in the new national standard is major, the compliance rate of almost essential compositions is high. A few of individual essential compositions in some commercial products cannot meet the new standards requirements, the main reason is those can not reach the increased new minimum requirements, especially on vitamin D.
