BACKGROUND: Spaceflight alters human cardiovascular dynamics. The less negative slope of the fractal scaling of heart rate variability (HRV) of astronauts exposed long-term to microgravity reflects cardiovascular deconditioning. We here focus on specific frequency regions of HRV. METHODS: Ten healthy astronauts (8 men, 49.1 ± 4.2 years) provided five 24-hour electrocardiographic (ECG) records: before launch, 20.8 ± 2.9 (ISS01), 72.5 ± 3.9 (ISS02) and 152.8 ± 16...

BACKGROUND: The prognostic value of nutritional status is poorly understood and evidence-based nutritional assessment indices are required in acute heart failure (AHF). We investigated the prognostic value of malnutrition assessed by the Controlling Nutritional Status (CONUT) score (range 0-12, higher=worse, consisting of serum albumin, cholesterol and lymphocytes) in AHF patients. METHODS: The CONUT score was measured on admission in 635 consecutive AHF patients...

Gastrointestinal stromal tumors represent the most common mesenchymal tumor of the digestive tract, driven by gain-of-function mutations in KIT. Despite its proven benefits, half of the patients treated with imatinib show disease progression within 2 years due to secondary resistance mutations in KIT. It remains unclear how the genomic and transcriptomic features change during the acquisition of imatinib resistance. Here, we performed exome sequencing and microarray transcription analysis for four imatinib-resistant cell lines and one cell line briefly exposed to imatinib...

High-dose chemotherapy and surgical treatment have improved the prognosis of osteosarcoma. However, more than 20% of patients with osteosarcoma still have a poor prognosis. We investigated the expression and function of casein kinase 2 (CK2) in osteosarcoma growth. We then examined the effects of CX-4945, a CK2 inhibitor, on osteosarcoma growth in vitro and in vivo to apply our findings to the clinical setting. We examined the expression of CK2α and CK2β by western blot analysis, and performed WST-1 assays using CK2α and CK2β siRNA or CX-4945...

Anti-epidermal growth factor receptor (EGFR) drugs such as erlotinib and gefitinib cause a side effect of hypomagnesemia, but chemotherapy to treat this has not yet been developed. The transient receptor potential melastatin 6 (TRPM6) channel is involved in the reabsorption of Mg(2+) in the renal tubule. We reported previously that the expression of TRPM6 is up-regulated by epidermal growth factor (EGF) in renal tubular epithelial NRK-52E and HEK293 cells. EGF-induced elevation of TRPM6 expression was inhibited by erlotinib, gefitinib, and lapatinib...

In order to clarify the histological localization of cadmium (Cd) in the placenta, we analyzed paraffin sections of placentas from rats with a single Cd exposure on gestation day 18 by the LA-ICP-MS imaging method compared with the histopathological changes. The placentas were sampled at 1 hour, 2 hours, 3 hours, 6 hours, and 24 hours after treatment. Histopathologically, the trophoblasts in the labyrinth zone of the Cd group showed swelling at 1 hour. At 2 and 3 hours, the trophoblasts showed swelling and vacuolar degeneration...

In patients with Parkinson's disease (PD), hyperactivated inflammation in the brain, particularly microglial hyperactivation in the substantia nigra (SN), is reported to be one of the triggers for the delayed loss of dopaminergic neurons and sequential motor functional impairments. We previously reported that (1) auraptene (AUR), a natural prenyloxycoumain, suppressed inflammatory responses including the hyperactivation of microglia in the ischemic brain and inflamed brain, thereby inhibiting neuronal cell death; (2) 7-isopentenyloxycoumarin (7-IP), another natural prenyloxycoumain, exerted anti-inflammatory and neuroprotective effects against excitotoxicity; and (3) 4'-geranyloxyferulic acid (GOFA), a natural prenyloxycinnamic acid, also exerted anti-inflammatory effects...

Thyroid storm is an endocrine emergency which is characterized by multiple organ failure due to severe thyrotoxicosis, often associated with triggering illnesses. Early suspicion, prompt diagnosis and intensive treatment will improve survival in thyroid storm patients. Because of its rarity and high mortality, prospective intervention studies for the treatment of thyroid storm are difficult to carry out. We, the Japan Thyroid Association and Japan Endocrine Society taskforce committee, previously developed new diagnostic criteria and conducted nationwide surveys for thyroid storm in Japan...

Objective To manage patients with viral hepatitis, it is important to screen for hepatitis, conduct a comprehensive examination if such screening is positive, administer antiviral treatment, and conduct surveillance for hepatocellular carcinoma (HCC). The proper execution of this strategy is expected to effectively reduce the number of deaths from viral hepatitis. Such an "optimal" follow-up for HCC surveillance is therefore important. This study aimed to determine the benefits of performing an optimal follow-up of patients with viral hepatitis...

AIMS: Right ventricular (RV) systolic dysfunction has been shown to be an independent predictor of clinical outcome in patients with chronic heart failure (CHF), and cardiac metaiodobenzylguanidine (MIBG) imaging also provides prognostic information. We aimed to evaluate the long-term predictive value of combining RV systolic dysfunction and abnormal findings of cardiac MIBG imaging on outcome in CHF patients. METHODS AND RESULTS: We enrolled 63 CHF outpatients with left ventricular ejection fraction (EF) <40% in a prospective cohort study...

Even though lysophospholipids have attracted much interest in recent years on account of their unique bioactivity, research related to lysophospholipids is usually hampered by problems associated with standard sample preparation and discrimination of regioisomers. Herein, we demonstrate a quick tin-chemistry-based synthetic route to lysophosphatidylethanolamines (LPEs) and its application in the positional analysis of hepatic LPEs in non-alcoholic steatohepatitis (NASH) model mice. We found that the preference of hepatic LPE regioisomer largely depends on the unsaturation of acyl chain in both control and NASH model mice...

Wnt1-Cre- and Wnt1-GAL4 double transgenic (dTg) mice are used to study neural crest cell lineages by utilizing either the Cre/loxP or the GAL4/UAS system. We have previously shown that these mice exhibit behavioral abnormalities that resemble certain behaviors of psychiatric disorders and histologic alterations in the cholinergic and glutamatergic systems in the brain. The objective of the current study was to extend the behavioral analyses in these mice and to determine whether there were any sex-specific differences in the prevalence or severity of these behaviors...

One-month duration of dual antiplatelet therapy (DAPT) has widely been adopted after bare-metal stent (BMS) implantation in the real clinical practice. However, it has not been adequately addressed yet whether DAPT for only 1-month could provide sufficient protection from ischemic events beyond 1-month after BMS implantation. We assessed the effects of short DAPT relative to prolonged DAPT on clinical outcomes with the landmark analysis at 2 month after BMS implantation. Among 13,058 consecutive patients enrolled in the CREDO-Kyoto registry cohort-2, this study population consisted of 4905 patients treated with BMS only in whom the information on the status of antiplatelet therapy was available at 2 month after stent implantation [single-antiplatelet therapy (SAPT) group: N = 2575 (acute myocardial infarction (AMI): N = 1257, and non-AMI: N = 1318), and DAPT group: N = 2330 (AMI: N = 1304, and non-AMI: N = 1026)]...
