Low ambient oxygen prevents atherosclerosis
Kang, Ju-Gyeong,Sung, Ho Joong,Amar, Marcelo J.,Pryor, Milton,Remaley, Alan T.,Allen, Michele D.,Noguchi, Audrey C.,Springer, Danielle A.,Kwon, Jaeyul,Chen, Jichun,Park, Ji-hoon,Wang, Ping-yuan,Hwang, Springer-Verlag 2016 Journal of molecular medicine Vol.94 No.3
<P>Large population studies have shown that living at higher altitudes, which lowers ambient oxygen exposure, is associated with reduced cardiovascular disease mortality. However, hypoxia has also been reported to promote atherosclerosis by worsening lipid metabolism and inflammation. We sought to address these disparate reports by reducing the ambient oxygen exposure of ApoE-/- mice. We observed that long-term adaptation to 10 % O-2 (equivalent to oxygen content at similar to 5000 m), compared to 21 % O-2 (room air at sea level), resulted in a marked decrease in aortic atherosclerosis in ApoE-/- mice. This effect was associated with increased expression of the anti-inflammatory cytokine interleukin-10 (IL-10), known to be anti-atherogenic and regulated by hypoxia-inducible transcription factor-1 alpha (HIF-1 alpha). Supporting these observations, ApoE-/- mice that were deficient in IL-10 (IL10-/- ApoE-/- double knockout) failed to show reduced atherosclerosis in 10 % oxygen. Our study reveals a specific mechanism that can help explain the decreased prevalence of ischemic heart disease in populations living at high altitudes and identifies ambient oxygen exposure as a potential factor that could be modulated to alter pathogenesis. Key messages Chronic low ambient oxygen exposure decreases atherosclerosis in mice. Anti-inflammatory cytokine IL-10 levels are increased by low ambient O-2. This is consistent with the established role of HIF-1 alpha in IL10 transactivation. Absence of IL-10 results in the loss of the antiatherosclerosis effect of low O-2. This mechanism may contribute to decreased atherosclerosis at high altitudes.</P>

Objective: We evaluated the potency of therapeutic angiogenesis using intramyocardial injection of naked DNA expressing two isoforms of hepatocyte growth factor (pCK-HGF-X7) in a porcine myocardial infarction model. Methods: Four weeks after left anterior descending coronary artery ligation, 14 pigs were allocated to pCK-Null (negative control, n=7) or pCK-HGF-X7 (n=7) treatment groups. Gated myocardial single photon emission computed tomography was performed 4 and 8 weeks following coronary ligation. The effect of pCK-HGF-X7 on capillary density in the gene-injected myocardium was examined by histological analysis using alkaline phosphatase staining. Results: Segmental myocardial perfusion of the underperfused area (@?70%) from coronary ligation increased in the pCK-HGF-X7 group (p=0.051), without significant differences in changes over time between the two groups (p=0.54). Systolic wall thickening (p=0.001), left ventricular end-diastolic (p=0.045) and end-systolic volumes (p=0.009), and left ventricular ejection fraction (p=0.041) changed in both groups without significant differences in changes over time between the two groups. The increase in the left stoke volume was higher in the pCK-HGF-X7 group than in the pCK-Null group (p=0.008). Histological analysis showed that capillary density was significantly higher in the pCK-HGF-X7 group than the pCK-Null group (p<0.001). Conclusion: Intramyocardial injection of pCK-HGF-X7 induced significant angiogenesis at infarct-border zone, and increased the left ventricular stroke volume probably caused by reverse remodeling process.

Segmental hair analysis and estimation of methamphetamine use pattern.
Han, Eunyoung,Yang, Heejin,Seol, Ilung,Park, Yunshin,Lee, Bongwoo,Song, Joon Myong Springer International ; Springer 2013 International journal of legal medicine Vol.127 No.2
<P>The aim of this study was to investigate whether the results of segmental hair analysis can be used to estimate patterns of methamphetamine (MA) use. Segmental hair analysis for MA and amphetamine (AP) was performed. Hair was cut into the hair root, consecutive 1?cm length segments and 1-4?cm length segments. Whole hair was also analyzed. The hair samples were incubated for 20?h in 1?mL methanol containing 1?% hydrochloric acid after washing the hair samples. Hair extracts were evaporated and derivatization was performed using trifluoroacetic anhydride in ethylacetate at 65?C for 30?min. Derivatized extract was analyzed by gas chromatography/mass spectrometry. The 15 subjects consisted of 13 males and two females and their ages ranged from 25 to 42 (mean, 32). MA and AP concentrations in the whole hair ranged from 3.00 to 105.10?ng/mg (mean, 34.53) and from 0.05 to 4.76?ng/mg (mean, 2.42), respectively. Based on the analysis of the 1?cm length segmental hair, the results were interpreted in a way to distinguish between continuous use of MA (n?=?10), no recent but previous use of MA (n?=?3), and recent but no previous use of MA (n?=?2). Furthermore, the individuals were interpreted as light, moderate, and heavy users based on concentration ranges previously published.</P>

<P>Allelic dropout due to stochastic variation in degraded small quantity DNA appears to be one of the most serious genotyping errors. Most methods require PCR replication to address this problem. The small amounts of valuable samples are often a limitation for such replications. We report a real-time PCR-based amelogonin Y (AMELY) allele dropout estimation model in an AMEL-based gender typing. We examined 915 replicates of AMELY-positive modern male DNA with varying amounts of DNA and humic acid. A male-specific AMEL fragment (AMELy) dropped out in 143 genuine male replicates, leading to gender typing errors. By graphing a scatter plot of the crossing point versus the end cycle fluorescence of the male replicates, a standard graph model for the estimation of the AMELy allele dropout was constructed with the dropout-prone and dropout-free zones. This model was then applied to ancient DNA (aDNA) samples. Nine samples identified as female were found in the dropout-prone zone; with higher DNA concentrations, six were shifted to the dropout-free zone. Among them, two female identifications were converted to male. All the aDNA gender was confirmed by sex-determination region Y marker amplification. Our data suggest that this model could be a basic approach for securing AMELy allele dropout-safe data from the stochastic variation of degraded inhibitory DNA samples.</P>
