ObjectivePatients with mesial temporal lobe epilepsy (mTLE) often exhibit central auditory processing (CAP) dysfunction. Monaural 40-Hz auditory steady-state magnetic responses (ASSRs) were recorded to explore the pathophysiology of mTLE.MethodsEighteen left mTLE patients, 11 right mTLE patients and 16 healthy controls (HCs) were examined. Monaural clicks were presented at a rate of 40 Hz. Phase-locking factor (PLF) and power values were analyzed within bilateral Heschl’s gyri.ResultsMonaural 40-Hz ASSR demonstrated temporal frequency dynamics in both PLF and power data. Symmetrical hemispheric contralaterality was revealed in HCs. However, predominant contralaterality was absent in mTLE patients. Specifically, right mTLE patients exhibited a lack of contralaterality in response to left ear but not right ear stimulation, and vice versa in left mTLE patients.ConclusionThis is the first study to use monaural 40-Hz ASSR with unilateral mTLE patients to clarify the relationship between CAP and epileptic focus. CAP dysfunction was characterized by a lack of contralaterality corresponding to epileptic focus.SignificanceMonaural 40-Hz ASSR can provide useful information for localizing epileptic focus in mTLE patients. 相似文献

We have previously reported the high levels of glutamic acid decarboxylase 65 autoantibodies (GAD65A) in patients with type 1 diabetes and autoimmune thyroid disease. Here we describe a 32-year-old Japanese female with a thirteen-year history of type 1 diabetes whose levels of GAD65A were elevated just after the emergence of anti-thyroid autoimmunity. At 19 years of age, she developed diabetic ketoacidosis and was diagnosed with type 1 diabetes. She had GAD65A, insulinoma-associated antigen-2 autoantibodies (IA-2A), and zinc transporter-8 autoantibodies (ZnT8A), but was negative for antibodies to thyroid peroxidase (TPOAb) and thyroglobulin (TGAb) at disease onset. ZnT8A and IA-2A turned negative 2-3 years after the onset, whereas GAD65A were persistently positive at lower level (approximately 40 U/mL). However, just after the emergence of TGAb at disease duration of 12.5 years, GAD65A levels were reelevated up to 5717 U/mL in the absence of ZnT8A and IA-2A. Her thyroid function was normal and TPOAb were consistently negative. She has a HLA-DRB1*03:01/*04:01-DQB1*02:01/*03:02 genotype. Persistent positivity for GAD65A might be associated with increased risk to develop anti-thyroid autoimmunity. 相似文献

BackgroundPrimary spontaneous pneumothorax (PSP) occurs more frequently in young, tall men, with approximately 10,000 times video-assisted thoracoscopic surgery (VATS) annually in Japan is undergoing for surgical treatment. The underlying mechanisms remain unclear, but several reports have suggested correlation with weather conditions. This study aimed to evaluate the relationship between onset of PSP and changes in weather.MethodsWe retrospectively analyzed data from 112 patients who underwent VATS for PSP in Iwate, Japan from 1 January 2010 to 14 June 2020. Of the 3,818 days in this study period, the day on which the patient became aware of symptoms was classified as the PSP onset day (n=112), and all others were classified as PSP non-onset day (n=3,706). Meteorological data were collected from airbase station using an online source for the same place and same time. Logistic regression modeling was used to obtain predicted risks for the onset of PSP with respect to weather conditions.ResultsAmong the meteorological parameters, significant differences were mainly found at 2 days before onset for increasing average temperature [odds ratio (OR): 1.97, P=0.018], minimum temperature (OR: 1.97, P=0.018), average humidity (OR: 1.58, P=0.043), and decreased the sunshine time (OR: 2.26, P=0.012). No significant difference was observed in atrophic pressure at 2 days before onset.ConclusionsOnset of PSP may correlate with the increased temperature and humidity, seen with an approaching of warm front. 相似文献

Objective: The objective of this study was to determine the effects of a continuous infusion of low-dose hANP on the lungs during cardiac surgery in patients under cardiopulmonary bypass (CPB).Methods: We analyzed 30 consecutive cases of cardiac surgery performed at our hospital from 2007–2008. The patients were divided into a group that received hANP (hANP group) or a group that received saline and no hANP (N-hANP group). We measured various parameters before and after surgery using a PiCCO monitor.Result: There were no differences in the preoperative characteristics between the groups, although urine volume during the operation was significantly greater in the hANP group. After surgery, there were no significant differences between the groups in cardiac output index (CI), global enddiastolic volume index (GEDVI), intrathoracic blood volume index (ITBI), pulmonary blood volume index (PBI), extravascular lung water index (ELWI) and pulmonary vascular permeability index (PVPI), total protein, and creatine. In contrast, interleukin-6 (IL-6) and renin were significantly lower, and albumin was significantly higher in the hANP group.Conclusion: We found that low-dose hANP during open cardiac surgery inhibited the secretion and plasma activity of IL-6 and renin. Although there were no differences in lung circulatory parameters such as the amount of fluid in the pulmonary blood vessels between the two groups, we believe that the strong diuretic effect of hANP reduced third-space fluid retention caused by CPB. 相似文献

Gene doping is a threat to fair competition in sports, both human and equestrian. One method of gene doping is to administer exogenous genetic materials, called transgenes, into the bodies of postnatal humans and horses. Polymerase chain reaction (PCR)-based transgene detection methods such as digital PCR and real-time PCR have been developed for gene doping testing in humans and horses. However, the significance of PCR inhibitors in gene doping testing has not been well evaluated. In this study, we evaluated the effects of PCR inhibitors on transgene detection using digital PCR and real-time PCR against gene doping. Digital PCR amplification was significantly inhibited by high concentrations of proteinase K (more than 0.1 μg/μl), ethylenediaminetetraacetic acid (more than 5 nmol/μl), and heparin (more than 0.05 unit/μl) but not by ethanol or genomic DNA. In addition, phenol affected droplet formation in the digital PCR amplification process. Real-time PCR amplification was inhibited by high concentrations of phenol (more than 1% v/v), proteinase K (more than 0.001 μg/μl), ethylenediaminetetraacetic acid (more than 1 nmol/μl), heparin (more than 0.005 unit/μl), and genomic DNA (more than 51.9 ng/μl) but not by ethanol. Although both PCR systems were inhibited by nearly the same substances, digital PCR was more robust than real-time PCR against the inhibitors. We believe that our findings are important for the development of better methods for transgene detection and prevention of false negative results in gene doping testing. 相似文献
