    Abstract Background and objectives: We have recently found an H
    Methods: We investigated the uptake and efflux of quinidine in MDCK cells.
    Results: The uptake of 100 µM quinidine into MDCK cells was decreased by acidification of extracellular pH or alkalization of intracellular pH. In addition, the uptake of quinidine was highly temperature sensitive, but was extracellular Na
    Conclusions: The present findings suggested that the renal new antiport system is involved in the bidirectional membrane transport of quinidine in MDCK cells.

    Abstract RNase H acts as a key effector in gene knockdown by antisense oligonucleotides (ASOs). Although various chemical modifications have been developed to regulate RNase H-mediated cleavage, precise control is yet to be achieved. In this study, we tried to address the question of whether the interaction of phosphate groups or deoxyriboses is more important in the recognition of DNA/RNA duplex by RNase H. To answer this question, we investigated the effect of methylene group insertion at the 5'-upstream or 3'-downstream phosphorothioate groups on RNase H-mediated cleavage. By inserting a methylene group at the 5'-upside or 3'-downside, the distance between phosphates or deoxyriboses could be changed in a different pattern. Maximum suppression of the cleavage reaction was observed when a methylene group was inserted at the 5'-phosphate group of the nucleoside which is known to distinguish ribose and deoxyribose

    Abstract Background: Despite numerous studies of peripancreatic inflammatory fluid collection (PIFC) that report on the relevance of the drain amylase concentration (D-AMY), early prediction using this assay is problematic. This study aimed to investigate the clinical significance of measuring the D-AMY at 3 h after gastrectomy (POD0) for gastric cancer.
    Methods: This retrospective analysis included consecutive patients who underwent gastrectomy combined with peripancreatic lymph node dissection. The predictive value of D-AMY on POD0 and postoperative day 1 (POD1) for clinically relevant PIFC was evaluated together or individually.
    Results: Analyses were performed in 204 patients. Twenty (9.8%) patients experienced PIFC. D-AMY cutoffs of 721 IU/L on POD0 and 1695 IU/L on POD1 were determined using the receiver operating characteristic curve analysis for predicting PIFC. The D-AMY on POD0 had higher sensitivity (80%) but lower specificity (66.3%) for prediction of PIFC, compared with those of D-AMY on POD1 (65%, 89.1%, respectively). When combination marker analysis was performed, the highest risk group (D-AMY ≥ the cutoff values of POD0 and POD1) were associated with an elevated rate of occurrence (44%) and a high positive likelihood ratio (7.36) compared with those of the single cutoff group. The lowest risk group (D-AMY < the cutoff values on POD0 and POD1) was associated with a low rate of occurrence (2.5%) and low negative likelihood ratio (0.24) compared with those of the single cutoff group.
    Conclusions: Combined measurements of D-AMYs on POD0 and POD1 enhanced early prediction of PIFC after gastrectomy.

    Abstract This work assessed solvent isotope effects on the photoracemization rate and emission lifetime for [Ru(bpy)3]2+ (bpy = 2,2'-bipyridine) in water. An analysis of the effects of temperature on photoracemization rate and emission lifetime demonstrated that the transition from one enantiomer to the other is unaffected by the isotopic composition of the solvent. The results also showed that deactivation from the metal-to-ligand charge-transfer (3MLCT) excited state to the ground state is responsible for the solvent isotope effect on the photoracemization rate. The photoracemization reaction was found to proceed via a bond-breaking mechanism. In this process, a five-coordinated species produced through breaking of the Ru-N bond in the 3d-d* state undergoes a structural change to produce an achiral five-coordinated species. An analysis of the effect of temperature on emission lifetime, excluding the activation to the 3d-d* state that leads to the structural change, showed that the solvent isotopic composition affects deactivation from the 4th MLCT state.

    Abstract Objective Several studies have suggested that high dietary Na/K ratio and body mass index (BMI) increase the prevalence of hypertension. However, there have been a few reports on the combination of these two factors and their relationship with hypertension. This study aimed to examine the association of the combined estimated 24-h urinary Na/K ratio (24h-u-Na/K) (high or low) and BMI (high or low) with the risk of high blood pressure.Method We performed a cross-sectional study involving 1,112 participants (340 men and 772 women) of the Kobe Orthopedic and Biomedical Epidemiological study (KOBE study) who had no cardiovascular diseases or current anti-hypertensive medications. Sex-specific analyses were performed. The 24h-u-Na/K ratio was calculated from an estimation formula using collected spot urine. Participants were divided into four groups based on their 24h-u-Na/K ratio (low or high) and BMI (low or high), with the cutoff points being the median and 25 kg/m

    Abstract The effect of the sodium-to-potassium ratio (Na/K) on renal function within the clinically normal range of renal function are limited. We investigated the effects of an estimated 24 h urinary Na/K (e24hUNa/K) on a 6-year renal function decline among 927 urban Japanese community dwellers with no history of cardiovascular diseases and medication for hypertension, diabetes, or dyslipidemia. We partitioned the subjects into quartiles according to the e24hUNa/K. The estimated glomerular filtration rate (eGFR) was calculated using the chronic kidney disease epidemiology collaboration (CKD/EPI) formula and renal function decline was defined as an absolute value at or above the third quartile of the eGFR decline rate. A multivariable logistic regression model was used for estimation. Compared with the first quartile of the e24hUNa/K, multivariable-adjusted odds ratios (ORs) for eGFR decline in the second, third, and fourth quartiles were 0.96 (95% confidence interval: 0.61-1.51), 1.06 (0.67-1.66), and 1.65 (1.06-2.57), respectively. These results were similar when the simple spot urine Na/K ratio was used in place of the e24hUNa/K. Apparently healthy urban residents with an almost within normal range mean baseline eGFR and high e24hUNa/K ratios had an increased risk for a future decline in renal function. Reducing the Na/K ratio may be important in the prevention of chronic kidney disease in its early stage.
