The purpose of this study was to investigate the effect of vitamin {TEX}$B_{6}${/TEX} deficiency on the utilization and recuperation of stored fuel in exercising rats. Thirty six rats were fed either a vitamin {TEX}$B_{6}${/TEX} deficient diet(-{TEX}$B_{6}${/TEX}) or a control diet(+{TEX}$B_{6}${/TEX}) for 5 weeks, then subdivided into 3 group: non-exercise group(NE), exercise group(EX), exercise and recuperation group(EX). EX group were exercised in treadmill({TEX}$10^{o}${/TEX}, 0.5~0.8km/h)for 2 hours and ER group were recuperated three days with the respective diet after exercise. Glucose(GLU), glycogen(GLY), protein(PRO), trigyceride(TG) and free fatty acid(FFA) were compared in plasma(P), liver(L) and skeletal muscle(M) of rats. Compared to +{TEX}$B_{6}${/TEX} rats, in NE group, the level of L-GLY of -{TEX}$B_{6}${/TEX} rats was higher, M-TG, L-PRO of -{TEX}$B_{6}${/TEX} rats were lower and there were no differences in P-PRO, P-FFA, P-TG, M-GLY, M-PRO and L-TG. In EX group, the levels of P-FFA, L-PRO of -{TEX}$B_{6}${/TEX} rats were higher. P-TG, L-TG of -{TEX}$B_{6}${/TEX} rats were lower and there was no difference in L-GLY. In EG group, the levels of P-GLU, P-PRO, P-RG, L-PRO of -{TEX}$B_{6}${/TEX} rats were lower and there were no differences in L-GLY, L-TG, M-TG and M-GLY. these results suggest that a lowered intake of vitamin {TEX}$B_{6}${/TEX} may impair the recuperation of aminals after exercise related to exercise fuel stores although there is a compensation among stored fuel utilization during exercise.

Vitarnin A levels of egg yolk from hens fed diets supplemented with vitamin A increased slowly up to Week 4, while the values rapidly increased thereafter. The highest value(360% of initial value) was observed at Week 8 in birds fed 64,000 IU of vitamin A/kg diet. On the other hand, the contents of vitamin E in egg yolk rapidly increased in the first 2 weeks of the experiment and then stabilized up to Week 8. However, the efficiency of egg transfer decreased(P<0.05) as dietary vitamins A and E levels increased. It took at least 4 weeks for the increased levels of vitamin A and E in eggs from hens fed diets supplemented with each vitamin to recover the normal levels. Vitamin E levels of egg yolk in hens fed the vitamin A supplemented diets decreased as dietary vitamin A level increased (P<0.05). On the other hand, a slightly reduced levels of vitamin A levels of egg yolks from hens fed the vitamin E supplemented diet for 4 weeks of experiment was recovered back to control level at Week 8(P<0.05). Supplemental vitamin A markedly decreased the yolk deposition of vitamin F when two vitamins were supplemented simultaneously. The yolk deposition of vitamin A decreased as high level of vitamin B was supplemented, suggesting an antagonistic interactions between the two vitamins.

This survey was carried out to study the difference of nutrient intake, food behavior and health condition according to food intake diversity in the elderly(age 65 year over and 74 year under) in a local city. A diet survey with one day 24-recall method was used for 216 subjects(65 male & 151 female). Based on a food intake diversity examination, including an evaluation of KDDS(Korean's Dietary Diversity Score ; counts the number of food groups consumed daily from total five food groups(cereal, meat, vegetable, dairy, and oil groups)), Meal Balance(apply the KDDS at breakfast, lunch and dinner), and DVS(Dietary Variety Score ; total number of foods consumed), subjects were clustered according to food intake diversity. Food intake diversity patterns of male and female clusters were classified each into threes(Male-low group(24.6%), middle group(33.8%), and high group(41.5%)/Female low group(41.7%) middle group(37.1%), and high group(21.2%). The averages of KDDS, Meal Balance and DVS were 3.0, 7.5, 14.8 in the male middle group, and 4.5, 10.2, 25.7 in the male high group, 2.7, 6.3, 14.3 in the female low group, 4.0, 8.6, 18.0 in the female middle group, and 4.5, 10.5, 25.7 in the female high group respectively. The average dairy intake of nutrients below the RDA were energy, protein, Ca, Fe, Vitamin A, Vitamin B$_2$and niacin in the male low group, energy, protein, Ca, Fe, Vitamin A, Vitamin B$_2$in the male middle group and energy, Ca, Vitamin B$_2$in the male high group but a little. Also the female low group had intakes of all nutrients except Vitamin C, the middle group had intakes of energy, protein, Ca, Fe, Vitamin A, Vitamin B$_2$, and the female high group had intakes of energy, Ca, Vitamin A below the RDA respectively. Food intake diversity increasing, nutrient intake, food behavior and health condition proved to be good. This study explored the usefulness of cluster analysis in identifying food intake diversity of three groups of the elderly in relation to their nutrient intake, food behavior and health conditions.

Vitamin D dependent rickets type 1A (VDDR1A) is an autosomal recessive disorder caused by mutations in CYP27B1. Clinical findings are growth retardation, hypotonia, muscle weakness, hypocalcemic seizures, and radiological features of rickets. We aimed to present the VDDR1A case with a genetic study of CYP27B1. The 14-month-old boy was admitted to the hospital due to a seizure. Serum calcium, phosphorus, alkaline phosphatase, parathyroid hormone (PTH), 25(OH) vitamin D, and 1,25(OH)2 vitamin D values were 5.1 mg/dL, 3.7 mg/dL, 705 IU/L, 429 pg/mL, 24.9 ng/mL, and 8.8 pg/mL, respectively. Radiological study showed cupping and fraying of the distal ulna and radius. The molecular genetic study revealed that the patient had a compound heterozygous mutation, $Phe443Profs^*24$ and c.589+1G>A, in CYP27B1. Genetic analysis of the family members presented that the mother was heterozygous for the mutation c.589+1G>A, and that the father was heterozygous for $Phe443Profs^*24$. The patient was treated with calcium lactate and calcitriol. Until now, six Korean patients with VDDR1A have been studied. Including this case, Korean patients with VDDR1A were found to have only three different mutations in 14 alleles, indicating that the mutation in the CYP27B1 gene is homogeneous in the Korean population.

This study aimed to find out the effect of vitamins on respiratory-related viral infections, including coronavirus disease 2019 (COVID-19), through the literature reviews. From January 2000 to June 2021, the studies (cohort studies, cross-sectional studies, case-control studies, randomized control trials) related to vitamins (vitamin A, D, E, C, B₆, folate, and B₁₂) and COVID-19/severe acute respiratory syndrome/Middle East respiratory syndrome/cold/influenza were selected from the PubMed, Embase, and Cochrane libraries and analyzed. The relationship between vitamins and virus-related respiratory diseases was identified. Through the review, 39 studies were selected on vitamin D, one study on vitamin E, 11 studies on vitamin C, and 3 studies on folate. Regarding COVID-19, 18 studies on vitamin D, 4 studies on vitamin C, and 2 studies on folate showed significant effects of the intake of these nutrients in preventing COVID-19. Regarding colds and influenza, 3 studies on vitamin D, 1 study on vitamin E, 3 studies on vitamin C, and 1 study on folate demonstrated that the intake of these nutrients significantly prevents these diseases. Therefore, this review suggested the intake of vitamins D, E, C, and folate is important for preventing respiratory diseases related to viruses, such as COVID-19, colds, and influenza. The relationship between these nutrients and virus-related respiratory diseases should be continuously monitored in the future.

The symbiotic nature of the relationship between algae and marine bacteria is well-studied among the complex microbial interactions. The mutual profit between algae and bacteria occurs via nutrient and vitamin exchange. It is necessary to analyze the genome sequence of a bacterium to predict its symbiotic relationships. In this study, the genome of a marine bacterium, Pseudoruegeria sp. M32A2M, isolated from the south-eastern isles (GeoJe-Do) of South Korea, was sequenced and analyzed. A draft genome (91 scaffolds) of 5.5 Mb with a DNA G+C content of 62.4% was obtained. In total, 5,101 features were identified from gene annotation, and 4,927 genes were assigned to functional proteins. We also identified transcription core proteins, RNA polymerase subunits, and sigma factors. In addition, full flagella-related gene clusters involving the flagellar body, motor, regulator, and other accessory compartments were detected even though the genus Pseudoruegeria is known to comprise non-motile bacteria. Examination of annotated KEGG pathways revealed that Pseudoruegeria sp. M32A2M has the metabolic pathways for all seven vitamin Bs, including thiamin (vitamin B1), biotin (vitamin B7), and cobalamin (vitamin B12), which are necessary for symbiosis with vitamin B auxotroph algae. We also identified gene clusters for seven secondary metabolites including ectoine, homoserine lactone, beta-lactone, terpene, lasso peptide, bacteriocin, and non-ribosomal proteins.

Purpose: Food intake of COPD patients decreases because of appetite loss, depression, and breathing problems while eating, which increase the likelihood of patients becoming malnourished. This study investigated the nutrient intake and dietary quality of people with and without COPD in Korea. Methods: There were 2,160 adults aged 50 and over who participated in the $5{\sim}6^{th}$ Korea National Health and Nutrition Examination Survey. The subjects were divided into the COPD group and non-COPD group according to the rate of forced expiratory volume at 1 second (FEV1) against forced vital capacity (FVC). Consumption of food and nutrients were calculated based on the nutrition examination survey. Statistical analyses were conducted using SPSS 19.0. Results: Among individuals in their 50s, intake of vitamin $B_1$ in the COPD group was significantly less than the NCOPD group, while intake of sodium in the COPD group was significantly greater than the NCOPD group. Among individuals in their 60s, the energy intake of the COPD group was significantly less than that of the NCOPD group. The COPD group showed significantly less intake of vitamin $B_1$ and vitamin C, but greater intake of sodium than the NCOPD group. In the group aged 70 and over, The COPD group had significantly less intake of vitamin $B_1$ than the NCOPD group and showed lower nutrient adequacy ratio values in protein, vitamin $B_1$, vitamin $B_2$, and iron than the NCOPD group. Conclusion: The COPD group consumed less energy and certain nutrients, and their dietary quality was poor compared to the NCOPD group. Thus, more detailed research is required to understand the concrete relationship between COPD and malnutrition.
