Excessive fat deposition leads to obesity and cardiovascular diseases with abnormal metabolism. Pantothenic acid (PA) is a major B vitamin required for energy metabolism. However, the effect of PA on lipid metabolism and obesity has not been explored. We investigated the effects and molecular mechanism of PA on fat accumulation as well as the influence of adipogenic marker genes in both adult male mice and primary adipocytes. First, we demonstrated that PA attenuates weight gain in mice fed high-fat diet (HFD). Besides, PA supplementation substantially improved glucose tolerance and lipid metabolic disorder in obese mice. Furthermore, PA significantly inhibited white adipose tissue (WAT) deposition as well as fat droplets visualized by magnification in both chow and HFD group. More importantly, PA obviously suppressed the mRNA levels of CD36, IL-6, and TNF-α to alleviate inflammation and reduced the levels of PPARγ, aP2, and C/EBPα genes that are related to lipid metabolism in inguinal white adipose tissue (ing-WAT) and epididymal white adipose tissue (ei-WAT). In vitro, PA supplementation showed a lower lipid droplet aggregation as well as reduced expression levels of adipogentic genes. Finally, we identified that PA inhibits the phosphorylation levels of p38 and JNK in murine primary adipocytes. Collectively, our data demonstrated for the first time that PA attenuates lipid metabolic disorder as well as fat deposition by JNK/p38 MAPK signaling pathway.

Background: Attention deficit hyperactivity disorder (ADHD) is a common childhood neurodevelopmental disorder that begins before age 12. Given the role of B group vitamins in cell metabolism, synthesis of nucleotides, and neurotransmitters, the present study systematically investigated the plasma levels of vitamins B9 and B12 in children with ADHD. Methods: We searched electronic databases including Web of Science, MEDLINE, EMBASE, Scopus, Iran MEDEX, Cochran database, and SID from conception to June 2023. Full-text case-control or cross-sectional studies were included in this study. Participants in the case group were children with ADHD aged 6-12 years. Review Manager Software (RevMan 5.4) was used for statistical analyses. Standardized mean differences (SMD) with 95% CIs were used to determine the differences between the two groups. Results: Six studies were included in the present meta-analysis. They included 982 children, of whom, 204 were girls and 744 were boys. The mean age of the children was 8.86±2.03 years. The level of vitamin B9 was significantly different between children with and without ADHD [SMD -0.80, 95% CI (-1.55, -0.04)]. Vitamin B12 was significantly lower in children with ADHD [SMD -0.29, 95% CI (-0.42, -0.16)]. However, due to high heterogeneity (I2 = 93%), sensitivity analysis was used, I2 fell to 21%, and significant difference was observed between the two groups [SMD -0.19, 95% CI (-0.34, -0.04)]. Conclusion: The results of this systematic review showed that the level of vitamins B9 and B12 in children with ADHD was significantly lower than that in healthy children.

OBJECTIVE: To study the clinical and neurophysiological features of children with low cognitive tempo (NCT), as well as the effectiveness of the drug Pantogam in the treatment of this pathology.
METHODS: A total of 90 children aged 8 to 10 years were examined. Of these, the main study group consisted of 30 children with NCT, the comparison group consisted of 30 children with a combined type of attention deficit hyperactivity disorder ADHD (ADHD-K), the control group consisted of 30 children without neuropsychiatric disorders. The study used clinical, neurophysiological (electroencephalography (EEG)) and parametric methods. The CMAS scale of apparent anxiety (The Children\'s Form of Manifest Anxiety Scale), the SNAP-IY scale (assessment of the degree of inattention, hyperactivity and impulsivity), the TOVA computer test (the Test of Variables of Attention), the scale «SCT» (Sluggish Cognitive Tempo) for assessing manifestations of low cognitive tempo, the «RAM» technique for quantifying working memory. Pantogam was used to treat patients at a dose of 750 mg per day for 8 weeks.
RESULTS: Patients with NCT are characterized by more pronounced attention disorders compared with healthy peers and with children with ADHD-K, and they have a decrease in mainly not selective attention, but the overall level of functional activity. Also, the group of children with NCT has an increased level of anxiety compared to the group of children with ADHD. A comparative analysis of the level of impulsivity showed that children with NCT are less characterized by a deficit in inhibition processes. According to the quantitative analysis of the EEG, specific changes in functional activity in the frontal and central regions of the cerebral cortex were revealed (a statistically significant increase in the ratio of absolute theta rhythm to beta1 rhythm, compared with other groups), reflecting insufficient cortical arousal and less focused neural states. When re-evaluating the condition of children with NCT after a course of therapy with Pantogam, an improvement in the form of a decrease in the degree of inattention, the severity of memory impairment and a decrease in reaction time was recorded in 60% of cases. According to quantitative EEG analysis, there was a significant decrease in the ratio of absolute theta rhythm to beta1 rhythm in the central leads of both hemispheres and in the parietal-temporal leads of the left hemisphere, indicating an increase in the level of overall activation of the cerebral cortex after a course of treatment.
CONCLUSIONS: Clinical and neurophysiological differences were revealed in patients with NCT and with combined ADHD. It has been shown that the use of Pantogam for the treatment of children with NCT leads not only to a decrease in the main manifestations of this disorder, but also to an improvement in the functional state of the brain.
UNASSIGNED: Изучить клинические и нейрофизиологические особенности детей с низким когнитивным темпом (НКТ), а также эффективность применения препарата Пантогам в лечении данной патологии.
UNASSIGNED: Были обследованы 90 детей в возрасте от 8 до 10 лет. Из них основную исследуемую группу составили 30 детей с НКТ, группу сравнения — 30 детей с комбинированным типом синдрома дефицита внимания с гиперактивностью (СДВГ-К), контрольную группу — 30 детей без психоневрологических расстройств. В исследовании применялись клинический, нейрофизиологический (электроэнцефалография (ЭЭГ)) и параметрический методы. Использовались шкала явной тревожности CMAS (The Children’s Form of Manifest Anxiety Scale), шкала SNAP-IY (оценка степени невнимательности, гиперактивности и импульсивности), компьютерный тест TOVA (the Test of Variables of Attention), шкала SCT (Sluggish Cognitive Tempo) для оценки проявлений низкого когнитивного темпа, методика «Оперативная память» для количественной оценки рабочей памяти. Для лечения пациентов использовался препарат Пантогам в дозе 750 мг/сут в течение 8 нед.
UNASSIGNED: Пациенты с НКТ характеризуются более выраженными нарушениями внимания по сравнению со здоровыми сверстниками и детьми с СДВГ-К, причем у них отмечается снижение преимущественно не селективного внимания, а общего уровня функциональной активности. Также у группы детей с НКТ отмечается повышенный уровень тревожности по сравнению с группой детей с СДВГ. Сравнительный анализ уровня импульсивности показал, что для детей с НКТ менее характерен дефицит процессов торможения. По данным количественного анализа ЭЭГ выявлены специфические изменения функциональной активности во фронтальных и центральных областях коры головного мозга (статистически значимое, по сравнению с другими группами, увеличение отношения абсолютных мощностей тета-ритма к бета1-ритму), отражающие недостаточное возбуждение коры и менее сфокусированные нейронные состояния. При повторной оценке состояния детей с НКТ после курса терапии препаратом Пантогам улучшение в виде снижения степени невнимательности, выраженности нарушения оперативной памяти и уменьшения времени реакции было зарегистрировано в 60% случаев. По данным количественного анализа ЭЭГ отмечалось значимое уменьшение отношения абсолютных мощностей тета-ритма к бета1-ритму в центральных отведениях обоих полушарий и в теменно-височных отведениях левого полушария, свидетельствующее об увеличении уровня общей активации коры головного мозга после курса лечения.
UNASSIGNED: Выявлены клинические и нейрофизиологические различия у пациентов с НКТ и с комбинированным СДВГ. Показано, что применение препарата Пантогам для лечения детей с НКТ приводит не только к уменьшению основных проявлений этого расстройства, но и к улучшению функционального состояния головного мозга.

OBJECTIVE: To establish an ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) method for simultaneous determination of 11 nutritional components(thiamine, riboflavin, nicotinamide, nicotinic acid, pantothenic acid, pyridoxine, pyridoxal, pyridoxamine, biotin, choline, L-carnitine) in liquid milk.
METHODS: Milk samples were shaken with 20 mmol/L ammonium formate solution and heated in a water bath at 100 ℃ for 30 min, then incubated with papain and acid phosphatase at 45 ℃ for 16 h, the lower liquid was collected after centrifugation for analysis. UPLC separation was performed on an ACQUITY~(TM) HSS T3(3.0 mm×150 mm, 1.8 μm) column, 2 mmol/L ammonium formate(containing 0.1% formic acid) solution and acetonitrile(containing 0.1% formic acid) were used as mobile phase. Quantitative detection was performed by internal standard method.
RESULTS: 11 nutritional components can be effectively separated and detected in 12 min, and the linear correlation coefficients(R~2) were all above 0.995. The limits of detection(LODs) were between 0.05 and 0.50 μg/L, and the limits of quantification(LOQs) were between 0.20 and 1.25 μg/L. The recovery rates of three-level addition were 85.6%-119.3%, and the precision RSDs were between 3.68% and 7.82%(n=6). Based on the detection of 60 liquid milk samples from 5 different animals, it was found that the contents of 11 nutrients in liquid milk from different milk sources were significantly different, but pyridoxine could not be detected.
CONCLUSIONS: The method can quantitatively detect 11 water-soluble nutrients, including free and bound forms, by effective enzymolysis. It is sensitive, reproducible and can meet the needs of quantitative detection.

UNASSIGNED: Localized pantothenic acid deficiencies have been observed in several neurodegenerative diseases such as Alzheimer\'s disease (AD), Parkinson\'s disease dementia (PDD), and Huntington\'s disease (HD), indicating downstream energetic pathway perturbations. However, no studies have yet been performed to see whether such deficiencies occur across the dementia with Lewy bodies (DLB) brain, or what the pattern of such dysregulation may be.
UNASSIGNED: Firstly, this study aimed to quantify pantothenic acid levels across ten regions of the brain in order to determine the localization of any pantothenic acid dysregulation in DLB. Secondly, the localization of pantothenic acid alterations was compared to that previously in AD, PDD, and HD brains.
UNASSIGNED: Pantothenic acid levels were determined in 20 individuals with DLB and 19 controls by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) across ten brain regions. Case-control differences were determined by nonparametric Mann-Whitney U test, with the calculation of S-values, risk ratios, E-values, and effect sizes. The results were compared with those previously obtained in DLB, AD, and HD.
UNASSIGNED: Pantothenic acid levels were significantly decreased in six of the ten investigated brain regions: the pons, substantia nigra, motor cortex, middle temporal gyrus, primary visual cortex, and hippocampus. This level of pantothenic acid dysregulation is most similar to that of the AD brain, in which pantothenic acid is also decreased in the motor cortex, middle temporal gyrus, primary visual cortex, and hippocampus. DLB appears to differ from other neurodegenerative diseases in being the only of the four to not show pantothenic acid dysregulation in the cerebellum.
UNASSIGNED: Pantothenic acid deficiency appears to be a shared mechanism of several neurodegenerative diseases, although differences in the localization of this dysregulation may contribute to the differing clinical pathways observed in these conditions.
Decreases in a molecule called pantothenic acid (also known as vitamin B5) have been observed in several areas of the brain in multiple dementia disease, including Alzheimer’s disease, Parkinson’s disease dementia, and Huntington’s disease. However, it is unknown whether such changes also occur in another dementia disease, dementia with Lewy bodies, which shows many of the same symptoms and molecular changes as these conditions. As such, this study was performed in order to determine if and where changes in pantothenic acid occur throughout the dementia with Lewy bodies brain. Using a methodology called liquid chromatography–mass spectrometry, which is able to measure pantothenic acid levels in a highly precise manner in brain tissues, we found that several regions of the dementia with Lewy bodies brain show decreases in pantothenic acid, including some involved in movement such as the substantia nigra and motor cortex, as well as regions associated with cognition and memory such as the hippocampus—looking most similar to the pattern of changes already seen in Alzheimer’s disease. It is possible that these changes contribute to the progression of dementia with Lewy bodies; however, further studies need to be performed to determine at what point these changes happen during the disease and how they may contribute to the development of symptoms.

Plants used in traditional medicine offer an affordable new alternative in tissue repair therapy. This study aimed to evaluate the effectiveness of the 5% Rhizophora mangle cream compared to the 5% dexpanthenol cream in healing open surgical wounds on the upper eyelid. A total of 18 patients were submitted to the experiment and divided into 2 groups with 9 patients each who used topically and daily 5% dexpanthenol cream (control group) or 5% R.mangle cream (intervention group) for 7 days. Clinical, morphometric and histomorphometric analyses of wounds and surgical procedures for skin removal were performed. In the morphometric analysis, all wounds treated with R.mangle and dexpanthenol creams showed complete macroscopic scars, without inflammatory signs and infection free. The skin hydration values in pre and post application periods of the cream were 43.82 ± 43.93 and 62.12 ± 67.40 respectively. The histomorphometric study showed lower values of epithelium distance in R. mangle group and higher in dexpanthenol group with significant difference between groups (p < 0.05). The R.mangle 5% cream proved to be effective in healing wounds of human upper eyelid skin with a significant improvement in epithelization compared to dexpanthenol 5% cream.

This study explored the effects of different vitamin B5 (VB5) levels on intestinal growth and function of weaned piglets. Twenty-one piglets (7.20 ± 1.11 kg) were included in a 28-day feeding trial with three treatments, including 0 mg/kg (L-VB5), 10 mg/kg (Control) and 50 mg/kg (H-VB5) of VB5 supplement. The results showed that: Large intestine weight/body weight was the highest in H-VB5 group, Control and H-VB5 groups had significantly higher villus height and villus height/crypt depth than the L-VB5 in the ileum (p < .05). Goblet cells (ileal crypt) and endocrine cells (ileal villus) significantly increased in Control and H-VB5 (p < .05). The H-VB5 group exhibited significantly higher levels of ki67 and crypt depth in the cecum and colon, colonic goblet cells and endocrine cells were both rising considerably (p < .05). Isobutyric acid and isovaleric acid were significantly reduced in the H-VB5 group (p < .05), and there was a decreasing trend in butyric acid (p = .073). At the genus level, the relative abundance of harmful bacteria such as Clostridium_Sensu_Structo_1 Strecto_1, Terrisporbacter and Streptococcus decreased significantly and the relative abundance of beneficial bacteria Turicibacter increased significantly in H-VB5 group (p < .05). Overall, the addition of 50 mg/kg VB5 primarily enhanced the morphological structure, cell proliferation and differentiation of the ileum, cecum and colon. It also had a significant impact on the gut microbiota and short-chain fatty acids.

In dry skin (DS), skin-barrier function is easily disturbed and moisturizing factors in the stratum corneum are reduced. Despite being a common condition, DS is often overlooked in patients with advanced age or comorbid diseases. In September 2022, specialists in dermatology and skin care met to discuss unmet needs and management of patients with DS with existing medical conditions or DS induced by ongoing pharmacological treatments. There was consensus about the need to improve the current understanding and management of DS in patients with comorbidities, including type 2 diabetes, chronic kidney disease, radiodermatitis, and photodamaged skin. Clinical guidance related to optimal treatment of DS in patients with advanced age or comorbid diseases is needed. Dexpanthenol-containing emollients have been shown to provide rapid relief from the symptoms and clinical signs of skin inflammation and are well-tolerated and effective in terms of moisturizing and soothing DS and maintaining skin-barrier function. Thus, dexpanthenol-containing emollients may play an important role in future management of DS. Further research is needed to elucidate the efficacy of dexpanthenol across the spectrum of DS, irrespective of comorbidity status or age.

OBJECTIVE: Does dexpanthenol work as an effective therapeutic agent against cyclophosphamide (CYC)-induced premature ovarian failure (POF) in rats?
METHODS: A total of 28 female Wistar Albino rats were randomly divided into four groups (n = 7 per group). The POF and POF plus dexpanthenol groups were intraperitoneally administered CYC at an initial dose of 50 mg/kg, followed by 8 mg/kg for 14 days. The dexpanthenol and POF plus dexpanthenol groups were both intraperitoneally administered dexpanthenol at a dose of 500 mg/kg/day for 15 days.
RESULTS: In the group administered CYC, the following was observed: a decrease in the ovarian index; a decrease in the numbers of primordial, primary, secondary and antral follicles; an increase in the number of corpus luteum and atretic follicles; a decrease in proliferation cell nuclear antigen immunoreactivity; a significant reduction in anti-Müllerian hormone and oestradiol levels; and an increase in serum FSH levels compared with controls. Dexpanthenol, on the other hand, reversed these effects. Quantitative reverse transcription polymerase chain reaction analyses showed that dexpanthenol increased Bcl-2, Akt1, mTOR, Nrf2 and HO-1 in CYC-induced ovarian tissues, but decreased Bax, Cas3, Hsp27, Hsp70, and Hsp90. Dexpanthenol treatment has a potential for inhibiting the intrinsic apoptotic pathway and oxidative stress levels in ovarian tissues via the downregulation of the mRNA expression of heat shock proteins and the activation of Nrf2/HO-1 pathways.
CONCLUSIONS: Our findings demonstrated that dexpanthenol is an effective agent against POF caused by CYC; however, further experimental and clinical data are needed to use it effectively.

Observational evidence suggests that human milk oligosaccharides (HMOs) promote the growth of commensal bacteria in early life and adulthood. However, the mechanisms by which HMOs benefit health through modulation of gut microbial homeostasis remain largely unknown. 2\'-fucosyllactose (2\'-FL) is the most abundant oligosaccharide in human milk and contributes to the essential health benefits associated with human milk consumption. Here, we investigated how 2\'-FL prevents colitis in adulthood through its effects on the gut microbial community. We found that the gut microbiota from adult mice that consumed 2\'-FL exhibited an increase in abundance of several health-associated genera, including Bifidobacterium and Lactobacillus. The 2\'-FL-modulated gut microbial community exerted preventive effects on colitis in adult mice. By using Bifidobacterium infantis as a 2\'-FL-consuming bacterial model, exploratory metabolomics revealed novel 2\'-FL-enriched secretory metabolites by Bifidobacterium infantis, including pantothenol. Importantly, pantothenate significantly protected the intestinal barrier against oxidative stress and mitigated colitis in adult mice. Furthermore, microbial metabolic pathway analysis identified 26 dysregulated metabolic pathways in fecal microbiota from patients with ulcerative colitis, which were significantly regulated by 2\'-FL treatment in adult mice, indicating that 2\'-FL has the potential to rectify dysregulated microbial metabolism in colitis. These findings support the contribution of the 2\'-FL-shaped gut microbial community and bacterial metabolite production to the protection of intestinal integrity and prevention of intestinal inflammation in adulthood.IMPORTANCEAt present, neither basic research nor clinical studies have revealed the exact biological functions or mechanisms of action of individual oligosaccharides during development or in adulthood. Thus, it remains largely unknown whether human milk oligosaccharides could serve as effective therapeutics for gastrointestinal-related diseases. Results from the present study uncover 2\'-FL-driven alterations in bacterial metabolism and identify novel B. infantis-secreted metabolites following the consumption of 2\'-FL, including pantothenol. This work further demonstrates a previously unrecognized role of pantothenate in significantly protecting the intestinal barrier against oxidative stress and mitigating colitis in adult mice. Remarkably, 2\'-FL-enhanced bacterial metabolic pathways are found to be dysregulated in the fecal microbiota of ulcerative colitis patients. These novel metabolic pathways underlying the bioactivities of 2\'-FL may lay a foundation for applying individual oligosaccharides for prophylactic intervention for diseases associated with impaired intestinal homeostasis.
