A 68-year-old man visited our hospital due to anorexia, weight loss and a fever. We diagnosed the patient with disseminated Mycobacterium avium complex (MAC) and confirmed the presence of interferon (IFN)-γ neutralizing autoantibodies (IFN-γAb). His lesions improved following antibiotic therapy, but chylous ascites (CA) developed seven months after treatment. CA was able to be controlled by subcutaneous octreotide and diet therapy. IFN-γAb is recognized as having a critical role in the pathogenesis of disseminated MAC disease, but its clinical features are not fully understood. CA may be a complication that develops during the treatment of disseminated MAC infection.Remarkable progress has been seen in monitoring systems using noninvasive ambulatory electrocardiograms (ECGs). In the Holter ECG system, 12-channel formats have been utilized as diagnostic tools, particularly for the detection of transient or silent myocardial ischemia and dynamic electrical disorders. In patients diagnosed with cryptogenic stroke, despite negative results on standard ECG tests, continuous ambulatory ECG monitoring for up to 30 days has been shown to increase the detection rate of transient atrial fibrillation. At present, a waterproof Holter ECG system is available. Recently, continuous late potential measurements using the time domain method and frequency domain T-wave alternans using the spectral analysis method for 24 hours have been applied to the Holter ECG and developed as novel risk stratification markers. Wearable ECG monitors that are built into belts, vests, wristbands, adhesive patches, and mobile smartphones have been used as fitness products for athletes and healthcare products for the general population. In the future, such devices may be used as remote monitoring tools for the detection of arrhythmias.Portal vein thrombosis (PVT) while using an angiogenesis inhibitor is relatively rare. A 70-year-old Asian man was diagnosed with PVT two months after initiating 5-fluorouracil/leucovorin, irinotecan, and bevacizumab therapy for rectal cancer with liver metastases. Because the metastases were small and shrinking, we suspected that the thrombosis might have been caused by bevacizumab-containing chemotherapy. We stopped bevacizumab and started apixaban, a direct oral anticoagulant (DOAC). Eight months later, the complete dissolution of the thrombus and recanalization of the portal vein were attained. Our case suggests that PVT can occur during bevacizumab-containing chemotherapy, and DOAC therapy might be beneficial for treating PVT in patients with cancer.Objective The QRS-T angle has been established as a repolarization marker. In the present study, we determined whether or not newly developed bundle branch block (BBB) affected the QRS-T angle in patients with a narrow QRS. Methods Twenty-four patients with newly developed BBB and no adverse cardiac events were retrospectively included. The frontal QRS-T angle was defined as the absolute value of the difference between the frontal plane QRS axis and the T-wave axis. These electrocardiogram parameters were serially measured in the settings of narrow QRS and BBB. Results Twelve patients had newly developed right BBB (RBBB), and 12 had newly developed left BBB (LBBB). selleck products The development of RBBB did not affect the QRS axis, T-wave axis of QRS-T angle (41° ±42° to 53° ±65°, p = 0.63). In contrast, the development of LBBB shifted the QRS axis to the left (25° ±29° to -18° ±31°, p = 0.003), resulting in an increased QRS-T angle (72° ±50° to 123° ±39°, p = 0.001). Regarding RBBB, an excellent correlation and agreement were found between the QRS-T angles in the setting of narrow QRS and RBBB (r = 0.88; p less then 0.001; bias, 2.9° ±20.9°). However, there was a significant bias between the QRS-T angles in the setting of narrow QRS and LBBB (51.9° ±40.4°; p = 0.001). Conclusion Our data suggested that the QRS-T angle in the setting of RBBB reflected the original QRS-T angle in the setting of narrow QRS well, whereas the QRS-T angle in the setting of LBBB did not.We compared the cytotoxic effects and tumor necrosis factor-α (TNF-α) production induced by 13 trans-octadecenoic acid positional isomers (trans-4-C181 to trans-16-C181) in RAW264.7 cells using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay and enzyme-linked immunosorbent assay, respectively. No significant differences were observed in the cytotoxic effects among the 13 trans-C181 positional isomers and control on RAW264.7 cells. TNF-α production significantly decreased by treatment of trans-4-C181 as compared to control, but no significant differences in TNF-α production were observed among other trans-C181 positional isomers and control. These results suggest that the double bond position in trans-C181 may affect TNF-α production in cells.Ayu sweetfish (Plecoglossus altivelis) is a diurnal freshwater fish that are surface swimmers and active under broad and short wavelength-dominated light. Biochemical analyses have shown that the ayu fish have abundant carotenoids including zeaxanthin in their integuments. Although zeaxanthin plays an important role in the physiological function of the retina, the amount and location of zeaxanthin in the ayu eye have not been accurately determined. In this study, circular dichroism spectral data and chiral high-performance liquid chromatography analysis showed that zeaxanthin was the primary carotenoid in the ayu eye, and the eye had the highest carotenoid content compared to those in the integuments, subcutaneous fat, and digestive tract. Interestingly, zeaxanthin in the ayu eyeball was expressed in the photoreceptor layer and near the retinal pigmented epithelium. In vitro assays showed that zeaxanthin could protect photoreceptors and retinal pigmented epithelial cell lines against the oxidative stress induced by exposure to L-buthionine-(S,R)-sulfoximine/glutamate. These findings indicate that zeaxanthin plays protective roles against oxidative stress in the vision of wild ayu.Previously, we reported that the polar lipid fraction from the golden oyster mushroom, Pleurotus citrinopileatus, suppresses colon injuries which result from apoptosis induced by inflammatory stresses in vivo and in vitro (Yamashita et al., J. Oleo Sci., 69, 751-757 (2020)). Here, we investigated the use of lipid classes in mushroom polar lipid fraction in alleviating colon injury using differentiated Caco-2 cells as an intestinal tract model. The mushroom polar lipid fraction was separated into four fractions using silica thin layer chromatography. Each mushroom polar lipid fraction suppressed lipopolysaccharide (LPS)-induced decreases in the viability of intestinal cells, and the effects of sphingolipid fractions were significantly stronger than those of fraction that did not contain sphingolipids. Addition of sphingolipid fractions suppressed the expression of apoptosis-related proteins (e.g., death receptors and caspases) in the LPS-treated cells. Mushroom polar lipids, especially sphingolipids suppress intestinal apoptosis induced by inflammatory stress, and highly polar sphingolipids may exert stronger suppressive effects.
