Riboflavin intake, MTRR genetic polymorphism (rs1532268), and gastric cancer risk in a Korean population: a case-control study

The vitamin B group, including riboflavin, plays paramount roles in one-carbon metabolism (OCM), and disorders related to this pathway have been linked to cancer development. The variants of genes encoding OCM enzymes and the insufficiency of B vitamins could contribute to carcinogenesis. Very few observational studies have revealed a relationship between riboflavin and gastric cancer (GC), especially under conditions of modified genetic factors. We carried out a study examining the association of riboflavin intake and its interaction with MTRR (rs1532268) genetic variants with GC risk among 756 controls and 377 cases. The odds ratios (ORs) and 95% confidence intervals (CIs) were evaluated using unconditional logistic regression models. We observed protective effects of riboflavin intake against GC, particularly in the female subgroup (OR=0.52, 95% CI 0.28-0.97, p-trend=0.031). In the MTRR (rs1532268) genotypes analysis, the dominant model showed that the effects of riboflavin differed between the CC and CT+TT genotypes. Compared with CC carriers, low riboflavin intake in T+ carriers was significantly associated with a 93% higher GC risk (OR=1.93, 95% CI 1.09-3.42, p-interaction=0.037). In general, higher riboflavin intake might help reduce the risk of GC in both CC and TC+TT carriers, particularly the T+ carriers, with marginal significance (OR=0.54, 95% CI 0.28-1.02, p-interaction=0.037). Our study indicates a protective effect of riboflavin intake against GC. Those who carry at least one minor allele and have low riboflavin intake could modify this association to increase GC risk in the Korean population.

Peripheral Facial Paresis and COVID-19 Case Report

Among the neurological complications that occurred during Corona Virus Disease 2019 (COVID-19) infection, peripheral facial paresis is one of the conditions that can occur both during and after the Severe Acute Respiratory Tract Syndrome Corona Virus 2 (SARS-CoV-2) infection period. We present the case of a young man, aged 29 years, who presented the appearance of a peripheral facial paresis on the 14th day after the onset of symptoms, isolation and PCR detection of SARS-CoV-2 infection. The patient was evaluated clinically, neurologically, underwent laboratory tests, EKG, chest Radiography, Magnetic Resonance Imaging (MRI)/Magnetic resonance Angiography (MRA) and received corticotherapy, gastric antisecretory medication, antiviral medication, vitamin B group, neurotrophic medication and facial gymnastics, with good evolution and complete remission of clinical symptoms after 21 days. It is particularly important to carefully evaluate patients during the isolation period, symptomatic/asymptomatic for COVID-19 infection, as a possible complication could be peripheral facial paresis, which is why, we should evaluate, detect and treat early to reduce any persistent long-term neurological effects. Future studies are needed to identify and correlate peripheral facial paresis with SARS-CoV-2 infection as well as to detect the causes of neurological complications during or after COVID-19 infection.

Butyrate Mitigates Weanling Piglets From Lipopolysaccharide-Induced Colitis by Regulating Microbiota and Energy Metabolism of the Gut–Liver Axis

Inflammatory bowel disorder is accompanied by the destruction of immunity homeostasis, gut microbiota perturbation, and chronic inflammatory liver diseases. Butyrate is known as a primary energy source for colonocytes and functional substances for mitigating pathological features of colitis. However, it is still unclear whether butyrate alleviates colitis progression by regulation of microbiota and metabolism in the gut–liver axis. In the present study, we aimed to determine the role of microbiota and metabolism of the gut–liver axis in ameliorating lipopolysaccharide (LPS)-induced colitis in piglets using protected butyrate administration. Eighteen crossbred male piglets were weaned at 30 days old and were randomly allocated to three treatments, with CON (basal diet), LPS (basal diet + LPS), and BT-LPS (basal diet + 3.0 g/kg protected butyrate + LPS). On days 19 and 21, piglets in the LPS and BT-LPS groups were intraperitoneally challenged with LPS at 100 μg/kg body weight. Butyrate administration significantly decreased LPS-induced rise in the clinical score of piglets and colonic histological scores and reduced the susceptibility to LPS-induced severe inflammatory response by decreasing proinflammatory (IL-1β, IL-6, IL-8, and TNF-α) cytokines. Butyrate supplementation accelerated the prevalence of Faecalibacterium and Lactobacillus by enhancing the tricarboxylic acid (TCA) cycle of colonocytes. Dietary supplementation with protected butyrate significantly targeted increased concentrations of butyric acid in the colon and portal venous circulation, and enhanced the TCA cycle in the gut–liver axis by mobilizing amino acid and vitamin B group as a coenzyme. Meanwhile, during this progress, LPS increased fatty acid synthesis that was reversed by butyrate treatment, which was reflected by decreased acylcarnitines. Butyrate-reshaped colonic microbial community and metabolism in the gut–liver axis contributed to morphology integrity and immunity homeostasis by promoting anti-inflammatory (IL-10 and TGF-β) cytokines and suppressing inflammatory mediator hypoxia-inducible factor 1α and its downstream response elements cyclooxygenase 2 and inducible nitric oxide synthase. These results identified the pivotal role of colonic microbiota and metabolism in the gut–liver axis for alleviating inflammatory progression and possible therapeutic targets.

STUDY OF THE VITAMINS CONTAINED IN THE DAHLIA EVELINE PLANT BY TITRIMETRIC AND CAPILLARY ELECTROPHORESIS METHODS

In this research work, we consider the biological active substances that make up the aboveground and underground parts of the plant Dahlia evelines. The role of biological active substances on the growing organism is more important, because They are involved in the regulation of metabolism, strengthening immunity and the function of the nervous system. The amount of vitamin C (ascorbic acid) contained in the Dahlia Eveline plant was determined by the titrimetric method, and the vitamin B group was determined by capillary electrophoresis on M-04-41-2005 “Drop-105” “Lumex”. The study revealed that vital vitamins are found in the fruits of the Dahlia Eveline plant, leaves, stems and flowers.

Does the Affinity of Cisplatin to B-Vitamins Impair the Therapeutic Effect in the Case of Patients with Lung Cancer-consuming Carrot or Beet Juice?

Background: Cisplatin (CisPt) has a well-recognized anticancer activity by interacting with DNA and inducing programmed cell death. However, theoretical studies performed on the molecular level suggest that such nonspecific interactions can also take place with many competitive compounds, such as vitamins containing aromatic rings with lone-pair orbitals. Objective: This work is a theoretical study on the initial Pt-N7(N1) bond formation with vitamins from B group and their comparison with values characterizing native purines. Methods: Geometries of studied structures were optimized with an aid of Gaussian 09 using the B3LYP functional with the 6-31G** basis set. Atomic orbitals of platinum were represented by the lanl2dz basis. Solvation free energies were evaluated by a self-consistent reaction field (SCRF) approach. A dielectric constant of 78 for water was used in the PCM continuum model computations along with radii Bondii. Results: The affinities of mono-aqua cis~[Pt(NH3)2Cl(H2O)]+ and di-aqua cis~ [Pt(NH3)2(H2O)2]2+ derivatives of Cisplatinum toward compounds belonging to the group of eight B vitamins were studied and compared to interactions with canonical purines. All the values of ΔGr unambiguously indicate that reactions with cisPt-diaqua are more preferable, but the comparison of ΔGr values obtained for compounds from vitamin B group and the ones characterizing complexes created by Guanine molecules indicates higher affinity of cisPt monomers toward purines. Conclusion: Based on the observations, the regular intake of vitamin-rich beetroot or carrot juices is strongly discouraged during anticancer therapy using CisPt drug. To confirm the results of the performed computational study, detailed clinical trials should be performed.
