Plasma S100A12 Levels and Peripheral Arterial Disease in End-Stage Renal Disease

Background: S100A12 is an endogenous ligand of the receptor for advanced glycation end products (RAGE). Plasma S100A12 levels are high in end-stage renal disease (ESRD) patients undergoing maintenance hemodialysis (HD). Peripheral arterial disease (PAD) is common in HD patients and is associated with increased cardiovascular morbidity and mortality rates in this population. To date, however, no study has specifically assessed the relationship between plasma S100A12 and PAD in HD patients. Methods: We conducted a cross-sectional study of 152 HD patients in our affiliated hospital. We investigated PAD history and patient characteristics and quantified plasma S100A12 levels in all participants. Results: HD patients with PAD (n = 26; 21.9 [13.6–33.4] ng/ml) showed significantly higher plasma S100A12 levels than HD patients without PAD (n = 126; 11.8 [7.5–17.6]ng/ml; p Conclusion: These results suggest that plasma S100A12 levels are strongly associated with PAD prevalence in ESRD patients undergoing HD

Examination of the Most Suitable Preparation Method for Pollen Observation by Scanning Electron Microscope

To examine the most suitable method to prepare pollen for scanning electronmicroscope observation, several fixation methods and dehydration (or drying) methods wereapplied to Arabidopsis and lily pollen obtained from flowers before and after flowering.Light and confocal laser microscope observations revealed that, in both plants, pollenobtained before flowering was swollen and wet, while that obtained after flowering wasshrunken and dry. For scanning electron microscopy, pollen was unfixed or fixed with 50%(eventually 100%) acetone, FAA (5% formalin with 50% ethanol and 5% acetic acid) or 6%glutaraldehyde solutions. It was then dried naturally in air or artificially by either criticalpoint-dry or freeze-dry machines, respectively. The results indicated that, for scanningelectron microscope observation of dry pollen, the most suitable treatment is natural dryingwithout fixation. On the other hand, to observe wet pollen, the combination of FAA orglutaraldehyde fixation with artificial drying using either machines is preferable, andfixation with acetone is unsuitable.テクニカルノー

Strong Evidence of a Combination Polymorphism of the Tyrosine Kinase 2 Gene and the Signal Transducer and Activator of Transcription 3 Gene as a DNA-Based Biomarker for Susceptibility to Crohn’s Disease in the Japanese Population

OBJECTIVE: An association between susceptibility to inflammatory bowel disease (IBD) and polymorphisms of both the tyrosine kinase 2 gene (TYK2) and the signal transducer and activator of transcription 3 gene (STAT3) was examined in a Japanese population in order to identify the genetic determinants of IBD. METHODS: The study subjects comprised 112 patients with ulcerative colitis, 83 patients with Crohn's disease (CD), and 200 healthy control subjects. Seven tag single-nucleotide polymorphisms (SNPs) in TYK2 and STAT3 were detected by PCR-restriction fragment length polymorphism. RESULTS: The frequencies of a C allele and its homozygous C/C genotype at rs2293152 SNP in STAT3 in CD patients were significantly higher than those in control subjects (P = 0.007 and P = 0.001, respectively). Furthermore, out of four haplotypes composed of the two tag SNPs (rs280519 and rs2304256) in TYK2, the frequencies of a Hap 1 haplotype and its homozygous Hap 1/Hap1 diplotype were significantly higher in CD patients in comparison to those in control subjects (P = 0.023 and P = 0.024, respectively). In addition, the presence of both the C/C genotype at rs2293152 SNP in STAT3 and the Hap 1/Hap 1 diplotype of TYK2 independently contributes to the pathogenesis of CD and significantly increases the odds ratio to 7.486 for CD (P = 0.0008). CONCLUSION: TYK2 and STAT3 are genetic determinants of CD in the Japanese population. This combination polymorphism may be useful as a new genetic biomarker for the identification of high-risk individuals susceptible to CD

Gender Inclusion in Climate Change Adaptation

There is increasing evidence that climate change has an impact on natural disasters, such as flooding, and on agricultural production, both of which have implications for gender issues. In this paper we briefly review issues related to gender and poverty and examine the relationships between gender and various indices, including the human development index (HDI), the gender inequality index (GII), the multiple poverty index (MPI), and the masculinity score (MAS). Although the HDI, GII, and MPI are strongly related, they are not related to the MAS index. We then look at systems of land ownership and inheritance and have found that, although the constitutions in many countries guarantee gender equality, many laws violate that principle, especially laws dealing with land ownership. In other cases, customary laws have priority over the formal legal system, resulting in gender-biased legal systems. Finally, we discuss an example of job recovery after a disaster and interview three female agricultural workers in Japan. In the recovery process after a natural disaster, women are often expected to take care of family members; this can prevent them from returning to their jobs and place them at greater risk of either losing their jobs or being demoted. The results of the interviews demonstrate the recent empowerment of women in agricultural production and that these women have strong adaptive abilities
