Abstract

FTO is the strongest known genetic susceptibility locus for obesity. Experimental studies in animals suggest the potential roles of FTO in regulating food intake. The interactive relation among FTO variants, dietary intake and body mass index (BMI) is complex and results from previous often small-scale studies in humans are highly inconsistent. We performed large-scale analyses based on data from 177 330 adults (154 439 Whites, 5776 African Americans and 17 115 Asians) from 40 studies to examine: (i) the association between the FTO-rs9939609 variant (or a proxy single-nucleotide polymorphism) and total energy and macronutrient intake and (ii) the interaction between the FTO variant and dietary intake on BMI. The minor allele (A-allele) of the FTO-rs9939609 variant was associated with higher BMI in Whites (effect per allele = 0.34 [0.31, 0.37] kg/m2, P = 1.9 × 10−105), and all participants (0.30 [0.30, 0.35] kg/m2, P = 3.6 × 10−107). The BMI-increasing allele of the FTO variant showed a significant association with higher dietary protein intake (effect per allele = 0.08 [0.06, 0.10] %, P = 2.4 × 10−16), and relative weak associations with lower total energy intake (−6.4 [−10.1, −2.6] kcal/day, P = 0.001) and lower dietary carbohydrate intake (−0.07 [−0.11, −0.02] %, P = 0.004). The associations with protein (P = 7.5 × 10−9) and total energy (P = 0.002) were attenuated but remained significant after adjustment for BMI. We did not find significant interactions between the FTO variant and dietary intake of total energy, protein, carbohydrate or fat on BMI. Our findings suggest a positive association between the BMI-increasing allele of FTO variant and higher dietary protein intake and offer insight into potential link between FTO, dietary protein intake and adiposity

16. Radiation-induced defects by secondary ionizing irradiation in Si-type optical fibers

Abstract

Optical fibers were irradiated with neutron fluxes from an atomic reactor. Characteristics of the irradiation loss with respect to transmission wavelengths were studied. We found that two types of absorption exist: that in the shorter wavelength and that in the longer wavelength. The absorption in the short wavelength, less than approximately 600 nm, increased with the increase in the irradiation time; however, the loss in the longer wavelength between approximately 600 and 900 nm increased with the irradiation time but saturated a few hours after the beginning of the irradiation. The difference is attributable to the fact that the absorption in the longer-wavelength range is related to the intrinsic defects in the optical fibers while the defects in the short-wavelength ranges are related to the breakdown of the SiO 2 network in optical fibers.

Abstract

Bilateral adrenal infarction is an extremely rare disease, and it has been reported that some coagulation abnormalities, including essential thrombocythemia (ET), exist in the background. We herein report a 76-year-old patient in whom the platelet count had been in the normal range at the onset of adrenal infarction but subsequently increased to 102×10 4 /μL at 7 months later, leading to the diagnosis of JAK2V617F-positive ET. As the presence of the JAK2V617F mutation increases the risk of thrombosis, Janus kinase 2 (JAK2) genetic testing should be considered in some cases of nonspecific unknown thrombosis, even if there are no obvious hematological findings, such as clonal hematopoiesis of indeterminate potential (CHIP).

Abstract

FTO is the strongest known genetic susceptibility locus for obesity. Experimental studies in animals suggest the potential roles of FTO in regulating food intake. The interactive relation among FTO variants, dietary intake and body mass index (BMI) is complex and results from previous often small-scale studies in humans are highly inconsistent. We performed large-scale analyses based on data from 177,330 adults (154 439 Whites, 5776 African Americans and 17 115 Asians) from 40 studies to examine: (i) the association between the FTO-rs9939609 variant (or a proxy single-nucleotide polymorphism) and total energy and macronutrient intake and (ii) the interaction between the FTO variant and dietary intake on BMI. The minor allele (A-allele) of the FTO-rs9939609 variant was associated with higher BMI in Whites (effect per allele = 0.34 [0.31, 0.37] kg/m(2), P = 1.9 × 10(-105)), and all participants (0.30 [0.30, 0.35] kg/m(2), P = 3.6 × 10(-107)). The BMI-increasing allele of the FTO variant showed a significant association with higher dietary protein intake (effect per allele = 0.08 [0.06, 0.10] %, P = 2.4 × 10(-16)), and relative weak associations with lower total energy intake (-6.4 [-10.1, -2.6] kcal/day, P = 0.001) and lower dietary carbohydrate intake (-0.07 [-0.11, -0.02] %, P = 0.004). The associations with protein (P = 7.5 × 10(-9)) and total energy (P = 0.002) were attenuated but remained significant after adjustment for BMI. We did not find significant interactions between the FTO variant and dietary intake of total energy, protein, carbohydrate or fat on BMI. Our findings suggest a positive association between the BMI-increasing allele of FTO variant and higher dietary protein intake and offer insight into potential link between FTO, dietary protein intake and adiposity., (© The Author 2014.

Abstract

In September and October, 2004, an outbreak of encephalopathy of unknown etiology occurred in certain areas of Japan including Yamagata, Akita, and Niigata prefectures. These patients had a history of chronic renal failure, most of them had undergone hemodialysis, and also had a history of eating Sugihiratake (Pleurocybella porrigens), an autumn mushroom without known toxicity. Since clinical details of this type of encephalopathy remain unknown, we analyzed the clinical, radiological and electroencephalographic (EEG) features of ten cases of this encephalopathy in Yamagata prefecture. The summary of the present study is as follows: 1. Ten patients had chronic renal failure, and seven underwent hemodialysis. 2. Each patient had a history of eating Sugihiratake within 2-3 weeks of the onset of neurological symptoms. 3. The onset was subacute; the initial symptoms were tremor, dysarthria, and/or weakness of the extremities, which lasted an average of 4.5 days (ranging from 2 to 11 days), followed by severe consciousness disturbance and intractable seizures, resulting in status epilepticus in 5 patients. Myoclonus was also seen in 4 patients and Babinski reflex in 3. 4. Brain CT and MRI examinations were unremarkable in the early stages of the disease. Three to eight days after onset, however, conspicuous lesions appeared in the areas of the insula and basal ganglia in 6 patients. On MRI, these brain lesions were hyperintense on T2-weighted and FLAIR images, and hypointense on T1-weighted images. 5. EEG examination was performed in 6 patients, all of whom showed abnormal EEG findings. Periodic synchronous discharge (PSD) was seen in 2 patients, spike and wave complex in one patient, and non-specific slow waves in 3. 6. Prognosis was different from case to case. Three patients died at 13, 14, and 29 days after onset. Two patients still showed persistent disturbance of consciousness one month after onset. One patient showed parkinsonism after recovering from consciousness disturbance. Four patients recovered nearly completely around one month after onset In 3 of the 4 recovered patients, renal failure was not severe and they did not need to undergo hemodialysis. This suggests that the degree of renal failure is a key for the prognosis of this type of encephalopathy. The present study suggests that this endemic disease is a newly recognized clinical entity of encephalopathy.
