ABSTRACT

Proso millet (Panicum miliaceum L.) and common wheat (Triticum aestivum L.) have been used as major crops in multiple regions since ancient times, and they contain various nutrients that can affect human hair health. This study investigated the various biological effects of a complex of millet extract and wheat extract (MWC) on hair health. Human immortalized dermal papilla cells (iDPCs) for an in vitro study and an anagen-synchronized mouse model for an in vivo study were employed. These findings revealed that the application of the MWC in vitro led to an increase in the mRNA levels of antioxidant enzymes (catalase and SOD1), growth factors (IGF-1, VEGF, and FGF7), and factors related to hair growth (wnt10b, ß-catenin) while decreasing inflammatory cytokine mRNA levels (IL-6 and TNFα). The mRNA levels of hair follicles (HFs) in the dorsal skin of the mouse model in the early and late telogen phases were also measured. The mRNA levels in the in vivo study showed a similar alteration tendency as in the in vitro study in the early and late telogen phases. In this model, MWC treatment elongated the anagen phase of the hair cycle. These findings indicate that the MWC can suppress oxidative stress and inflammation and may elongate the anagen phase by enhancing the growth factors involved in the wnt10b/ß-catenin signaling pathway. This study suggests that the MWC might have significant potential as a functional food for maintaining hair health.

ABSTRACT

Climate change will cause a range of related risks, including increases in infectious and chronic disease, intensified social and economic stresses, and more frequent extreme weather events. Vulnerable groups will be disproportionately affected due to greater exposure to climate risks and lower ability to prepare, adapt, and recover from their effects. Better understanding of the intersection of vulnerability and climate change risks is required to identify the most important drivers of future climate risks and effectively build resilience and deploy targeted adaptation efforts. Incorporating community stakeholder input, we identified and integrated available public health, social, economic, environmental, and climate data in the United States (U.S.), comprising 184 indicators, to develop a Climate Vulnerability Index (CVI) composed of four baseline vulnerabilities (health, social/economic, infrastructure, and environment) and three climate change risks (health, social/economic, extreme events). We find that the vulnerability to and risks from climate change are highly heterogeneous across the U.S. at the census tract scale, and geospatially cluster into complementary areas with similar climate risks but differing baseline vulnerabilities. Our results therefore demonstrate that not only are climate change risks both broadly and variably distributed across the U.S., but also that existing disparities are often further exacerbated by climate change. The CVI thus lays a data-driven, scientific foundation for future research on the intersection of climate change risks with health and other inequalities, while also identifying health impacts of climate change as the greatest research gap. Moreover, given U.S. government initiatives surrounding climate and equity, the CVI can be instrumental in empowering communities and policymakers to better prioritize resources and target interventions, providing a template for addressing local-scale climate and environmental justice globally.

ABSTRACT

BACKGROUND: Thermal injuries on free transferred or replanted tissues resulting from loss of sensibility are an infrequent occurrence. They require immediate and appropriate management before they progress to an irreversible condition. Although negative pressure wound therapy (NPWT) can prevent wound progression by increasing microcirculation, the inappropriate application of NPWT on complication-threatened transferred and replanted tissues can induce an adverse effect. CASE SUMMARY: A 48-year-old woman who underwent immediate breast reconstruction with a deep inferior epigastric artery perforator free flap. While applying a heating pad directly to the flap site, she sustained a deep second to third-degree contact burn over 30% of the transferred flap on postoperative 7 d. As the necrotic changes had progressed, we applied an NPWT dressing over the burned area after en-bloc debridement of the transferred tissues on postoperative 21 d. After 4 d of NPWT application, the exposed fatty tissues of the flap changed to dry and brown-colored necrotic tissues. Upon further debridement, we noted that the wound gradually reached total necrosis with a collapsed vascular pedicle of deep inferior epigastric artery. CONCLUSION: Although NPWT has been shown to be successful for treating various wound types, the significant risk of NPWT application in short-lasting reconstructed flap wounds after thermal injury should be reminded.

ABSTRACT

BACKGROUND: Reverse-flow posterior interosseous artery (rPIA) flap is an excellent tool for restoration of defects in the hand and upper extremity, sparing the main arteries to the hand. Its reliability has been well established. MATERIALS AND METHODS: Fifty-one cases of rPIA flap involving 49 patients were retrospectively reviewed. The inclusion criteria were age, sex, etiology, size and location of the defect, flap size, number of perforators included, pedicle length, flap inset, donor site coverage, complications, and ancillary procedures. RESULTS: This study included 44 men and 5 women, ranging in age between 10 and 73 years. The subjects had soft tissue defects of the hand and upper extremity mainly due to traumatic injuries, including scar contractures of the first web space in 18 cases, thumb amputations in 6 cases, and congenital defects in 1 case. Among the 51 rPIA flap elevations, 3 cases involved flap failure due to the absence of proper pedicle. A fasciocutaneous pattern was observed in 45 cases and a myocutaneous pattern in 3 cases. In 5 cases of unplantable thumb amputations, the rPIA flap was performed for arterial inflow to the secondary toe-to-thumb transfer. Venous congestion of varying degrees was noted in 7 cases involving partial necrosis in 2 cases. During the mean 17 months of follow-up, patients were generally satisfied with the final outcomes. CONCLUSION: The rPIA flap can be used not only for soft tissue coverage of the hand and upper extremity but also as a recipient arterial pedicle for a secondary toe-to thumb transfer.

ABSTRACT

Background: The anatomical structures in relation to the carpal tunnel release are the palmaris brevis muscle (PBM), transverse carpal ligament (TCL), and the recurrent motor branch of the median nerve (RMBMN). Our aim is to describe the gross morphology in the Korean population of the PBM, TCL, and RMBMN specifically looking for anomalies, and to determine the muscles encountered during a standard carpal tunnel release. Material and Methods: A total of 30 cadaveric hands were dissected. A longitudinal line drawn from the third web space to the midpoint of the distal wrist crease served as the reference line (RL). The PBM and TCL were classified according to its shape and location. The length, width, and thickness of the TCL were measured. The ratio of the lengths of PBM and TCL to RL was calculated. The course of the RMBMN was dissected specifically looking for anomalies. We also looked at the muscle fibers encountered during a standard carpal tunnel release to identify the muscle. Results: PBM was classified into three different types based on the shape. The average thickness of the PBM and TCL were 0.89 ± 0.16 mm and 1.43 ± 0.40 mm, respectively. The distal border of the TCL was thicker than the proximal border. The average ratio of the length of the PBM to the RL was 25.65 ± 8.62% and TCL to the RL was 24.00 ± 3.37%. The distribution of the RMBMN was classified into three different types. A few accessory branches of the RMBMN were also noted. And 36 muscle fibers were noted within the TCL in line with the RL. Conclusion: We clarified findings and added quantitative information about the anatomical structures surrounding carpal tunnel. A thorough knowledge of the anatomy and anomalies around the carpal tunnel is helpful for surgeons to ensure optimal surgical results.

ABSTRACT

There have been many studies suggesting that probiotics are effective in patients with diarrhea-predominant irritable bowel syndrome (IBS-D). However, its mechanism of action as well as prediction of response is still to be elucidated. In the present study, to find out metabolomic characteristics of probiotic effect in IBS-D, we compared IBS symptom changes and metabolomic characteristics in the subjects' urine samples between multi-strain probiotics (one strain of Lactobacillus sp. and four strains of Bifidobacterium sp.) group (n = 32) and placebo group (n = 31). After 8 weeks' administration (3 times/day), dissatisfaction in bowel habits and stool frequencies were significantly improved. Also, probiotics group had significantly changed seven metabolites including palmitic acid methyl ester (PAME) and 4,6-dihydroxyquinoline, 4-(2-aminophenyl)-2,4-dioxobutanoic acid (DOBA). According to IBS-SSS and IBS-QoL questionnaires, IBS-SSS responders showed higher PAME levels and IBS-QoL responders showed lower DOBA levels. This suggests potential role of these metabolites as a biomarker to predict probiotics effect in IBS-D patients.

ABSTRACT

Acid food indicators can be used as pH indicators for evaluating the quality and freshness of fermented products during the full course of distribution. Iron oxide particles are hardly suspended in water, but partially or completely agglomerated. The agglomeration degree of the iron oxide particles depends on the pH. The pH-dependent particle agglomeration or dispersion can be useful for monitoring the acidity of food. The zeta potential of iron oxide showed a decreasing trend as the pH increased from 2 to 8, while the point of zero charge (PZC) was observed around at pH 6.0-7.0. These results suggested that the size of the iron oxide particles was affected by the change in pH levels. As a result, the particle sizes of iron oxide were smaller at lower pH than at neutral pH. In addition, agglomeration of the iron oxide particles increased as the pH increased from 2 to 7. In the time-dependent aggregation test, the average particle size was 730.4 nm and 1,340.3 nm at pH 2 and 7, respectively. These properties of iron oxide particles can be used to develop an ideal acid indicator for food pH and to monitor food quality, besides a colorant or nutrient for nutrition enhancement and sensory promotion in food industry.

ABSTRACT

The aims of this study were to develop strategies and algorithms of calculating food commodity intake suitable for exposure assessment of residual chemicals by using the food intake database of Korea National Health and Nutrition Examination Survey (KNHANES). In this study, apples and their processed food products were chosen as a model food for accurate calculation of food commodity intakes uthrough the recently developed Korea food commodity intake calculation (KFCIC) software. The average daily intakes of total apples in Korea Health Statistics were 29.60 g in 2008, 32.40 g in 2009, 34.30 g in 2010, 28.10 g in 2011, and 24.60 g in 2012. The average daily intakes of apples by KFCIC software was 2.65 g higher than that by Korea Health Statistics. The food intake data in Korea Health Statistics might have less reflected the intake of apples from mixed and processed foods than KFCIC software has. These results can affect outcome of risk assessment for residual chemicals in foods. Therefore, the accurate estimation of the average daily intake of food commodities is very important, and more data for food intakes and recipes have to be applied to improve the quality of data. Nevertheless, this study can contribute to the predictive estimation of exposure to possible residual chemicals and subsequent analysis for their potential risks.

ABSTRACT

The effects of steaming time (6, 8, and 10 min), freezing storage period, and re-steaming for thawing on the textural properties of non-glutinous rice cakes (baekseolgi) were investigated. As the steaming time increased, the rice cakes softened. In particular, the sample that was steamed for 10 min showed lower hardness than those steamed for shorter periods. A short period of steaming was insufficient for water bound to the surface of the starch granules to penetrate the granules in the dough. During the re-steaming process of the frozen non-glutinous rice cake samples, the retrogradation of starch and water syneresis contributed to the increased hardness of non-glutinous rice cakes.

ABSTRACT

An protease from Actinidia arguta for improving meat tenderness was purified, characterized from wild A. arguta fruit by ammonium sulfate precipitation, Sephdex G-25 gel filtration chromatography, and DEAE Sepharose Fast Flow ion exchange chromatography, and its activity was investigated. The purified protease was subjected to sodium dodecyl sulfate polyacrylamide gel electrophoresis to obtain a single band of protease. The protease was purified successfully, and found to have a molecular weight of 23.8 kDa (mass spectrometry). The specific activity of the purified protease reached 53,428 U/mg with a 25.5-fold purification factor and 9% activity recovery. Based on N-terminal sequencing results, the A. arguta protease was derived from the class of actinidia proteases that have an N-terminal sequence of VLPDY VDWRS AGAVV. The protease was effective for tenderizing beef and decomposing actomyosin, suggesting the potential application for improving meat tenderness.

ABSTRACT

Metabolic alterations including postprandial hyperglycemia have been implicated in the development of obesity-related diseases. Xylose is a sucrase inhibitor suggested to suppress the postprandial glucose surge. The objectives of this study were to assess the inhibitory effects of two different concentrations of xylose on postprandial glucose and insulin responses and to evaluate its efficacy in the presence of other macronutrients. Randomized double-blind cross-over studies were conducted to examine the effect of D-xylose on postprandial glucose and insulin response following the oral glucose tolerance test (OGTT). In study 1, the overnight-fasted study subjects (n = 49) consumed a test sucrose solution (50 g sucrose in 130 ml water) containing 0, 5, or 7.5 g D-xylose powder. In study 2, the overnight-fasted study subjects (n = 50) consumed a test meal (50 g sucrose in a 60 g muffin and 200 ml sucrose-containing solution). The control meal provided 64.5 g of carbohydrates, 4.5 g of fat, and 10 g of protein. The xylose meal was identical to the control meal except 5 g of xylose was added to the muffin mix. In study 1, the 5 g xylose-containing solutions exhibited significantly lower area under the glucose curve (AUCg) and area under the insulin curve (AUCi) values for 0-15 min (P < 0.0001, P < 0.0001), 0-30 min (P < 0.0001, P < 0.0001), 0-45 min (P < 0.0001, P < 0.0001), 0-60 min (P < 0.0001, P < 0.0001), 0-90 min (P < 0.0001, P < 0.0001) and 0-120 min (P = 0.0071, P = 0.0016). In study 2, the test meal exhibited significantly lower AUCg and AUCi values for 0-15 min (P < 0.0001, P < 0.0001), 0-30 min (P < 0.0001, P < 0.0001), 0-45 min (P < 0.0001, P = 0.0005), 0-60 min (P = 0.0002, P = 0.0025), and 0-90 min (P = 0.0396, P = 0.0246). In conclusion, xylose showed an acute suppressive effect on the postprandial glucose and insulin surges.

ABSTRACT

CONTEXT: Hypoadiponectinemia is caused by interactions between genetic and environmental factors, including the quality of dietary fats. OBJECTIVE: We investigated the association of single-nucleotide polymorphisms (SNPs) in the adiponectin gene (ADIPOQ) with dietary fat intake or fatty acid (FA) composition in serum phospholipids, plasma adiponectin, and insulin resistance. METHODS: Nondiabetic subjects (n = 1194) were genotyped for three ADIPOQ SNPs (-11377C>G; 45T>G; 276G>T) after screening of eight sites. Dietary fat intake, FA composition in serum phospholipids, adiponectin, and homeostasis model assessment of insulin resistance (HOMA-IR) were also measured. RESULTS: The 276G carriers (n = 1082) showed lower high-density lipoprotein cholesterol (P = 0.024) and adiponectin (P < 0.001) but higher glucose (P = 0.015) and HOMA-IR (P = 0.005) than 276T/T subjects (n = 112). No associations were found in other SNPs. After adjusted for age, sex, body mass index, and the proportion of 18:2ω6 and 18:3ω3 (biomarkers of long term essential FA intake), the 276G carriers showed lower proportions of total ω3FA (P = 0.026), 20:5ω3 (P = 0.021), and 22:5ω3 (P = 0.024) in serum phospholipids. Among FAs in serum phospholipids, 18:2ω6 highly correlated with ω3-polyunsaturated FA (PUFA) intake (r = 0.260, P < 0.001) and adiponectin (r = 0.150, P < 0.001). The 276G carriers with a higher proportion of 18:2ω6 (≥12.5%) exhibited more pronounced characteristics, i.e. lower adiponectin (P < 0.001), lower high-density lipoprotein cholesterol (P = 0.004), higher HOMA-IR (P = 0.013), and lower long-chain ω3PUFAs (20:5ω3, 22:5ω3, and 22:6ω3, P < 0.001). Additionally, the effect of 276G>T on the relationship between adiponectin and HOMA-IR was modified by 18:2ω6 proportion. CONCLUSION: ADIPOQ 276G is associated with reduced proportion of long-chain ω3PUFAs in serum phospholipids in nondiabetic Koreans.
