Parathyromatosis

Tsung-Jui Wu, Ying-Tang Wang, Hung Chang, Shih-Hua Lin
2012 Kidney International  
A 45-year-old Chinese man on hemodialysis for 20 years was admitted with a 1-year history of progressive bone pain. He received left-sided video-assisted thoracoscopic surgery (VATS) to remove a mediastinal parathyroid adenoma 7 years ago. His serum intact parathyroid hormone (iPTH) concentration incrementally increased to 2500 pg/ml despite aggressive medical therapy over the past year. On examination, it was observed that he was kyphotic. Laboratory studies showed total calcium 2.8 mmol/l,

Singlephoton emission CT 99m Tc sestamibi scintigraphy ( Figure 1 ) demonstrated increased uptake at the left heart border and left chest wall in the delayed phase, suggesting functioning parathyroid nodules. Chest computed tomography ( Figure 2 ) identified three well-enhancing pleural nodules at the left cardiophrenic angle and another over the left chest wall. All four pleural parathyroid nodules were successfully removed by VATS and showed typical hyperplastic parathyroid tissue with microfollicular structure and uniform nuclei, confirming the diagnosis of parathyromatosis. Despite symptomatic improvement, a decreased but still abnormally elevated postoperative iPTH level (928 pg/ml) was ascribable to the presence of orthotopic parathyroid glands and residual tiny parathyroid nests spread over the surgical bed. With the use of intravenous 1,25 (OH) 2 vitamin D 3 at a dose of 2 mg three times weekly and calcium acetate at a dose of 4 gm daily for 3 months, his serum iPTH level was still around 750 pg/ml. Parathyromatosis is characterized by multiple benignappearing and functioning parathyroid nodules and can be classified into two types. 1 The less common type 1 refers to ontogenous parathyromatosis along the embryological developmental tract. The more common type 2 refers to postsurgical parathyromatosis due to inadvertent spillage of parathyroid cells during surgical extirpation. 2 Only 40% of parathyromatosis can be diagnosed preoperatively because of its scattered distribution and small size of individual cell nests. 3 The time from previous parathyroidectomy to the identification of parathyromatosis at reoperation ranges from 5 months to 19 years. 4 Parathyromatosis is not uncommon but under diagnosed. This case illustrates the importance of avoiding rupture of parathyroid capsule during the initial parathyroidectomy.

8-Hydroxydaidzein (8-OHD, 7,8,4′-trihydoxyisoflavone) is a hydroxylated derivative of daidzein isolated from fermented soybean products. The aim of this study is to investigate the anti-proliferative effects and the underlying mechanisms of 8-OHD in K562 human chronic myeloid leukemia (CML) cells. We found that 8-OHD induced reactive oxygen species (ROS) overproduction and cell cycle arrest at the S phase by upregulating p21Cip1 and downregulating cyclin D2 (CCND2) and cyclin-dependent kinase 6

(CDK6) expression. 8-OHD also induced autophagy, caspase-7-dependent apoptosis, and the degradation of BCR-ABL oncoprotein. 8-OHD promoted Early Growth Response 1 (EGR1)-mediated megakaryocytic differentiation as an increased expression of marker genes, CD61 and CD42b, and the formation of multi-lobulated nuclei in enlarged K562 cells. A microarray-based transcriptome analysis revealed a total of 3174 differentially expressed genes (DEGs) after 8-OHD (100 μM) treatment for 48 h. Bioinformatics analysis of DEGs showed that hemopoiesis, cell cycle regulation, nuclear factor-κB (NF-κB), and mitogen-activated protein kinase (MAPK) and Janus kinase/signal transducers and activators of transcription (JAK-STAT)-mediated apoptosis/anti-apoptosis networks were significantly regulated by 8-OHD. Western blot analysis confirmed that 8-OHD significantly induced the activation of MAPK and NF-κB signaling pathways, both of which may be responsible, at least in part, for the stimulation of apoptosis, autophagy, and differentiation in K562 cells. This is the first report on the anti-CML effects of 8-OHD and the combination of experimental and in silico analyses could provide a better understanding for the development of 8-OHD on CML therapy.

Rotating Black Holes and Coriolis Effect [article]

Xiaoning Wu and Yi Yang and Pei-Hung Yuan and Chia-Jui Cho
2015 arXiv   pre-print
In this work, we consider the fluid/gravity correspondence for general rotating black holes. By using the Petrov-like boundary condition in near horizon limit, we study the correspondence between gravitational perturbation and fluid equation. We find that the dual fluid equation for rotating black holes contains a Coriolis force term, which is closely related to the angular velocity of the black hole horizon. This can be seen as a dual effect for the frame-dragging effect of rotating black hole under the holographic picture.

Jui-Yu Lai, Yi-Jhen Liu, Hung-Yu Wu, Yen-Hung Chen, Shang-Da Yang
2010 Optics Express  
We propose and experimentally demonstrate a new scheme for flexible multiwavelength conversion that uses the genetic algorithm with two target functions to optimize the nonperiodic optical superlattice (NOS). Compared to the widely used aperiodic optical superlattice approach, our scheme can achieve ~15% higher overall conversion efficiency, better spectral fidelity, and allows for further improvement of the performances if a larger genetic pool is used. Numerical analysis also shows that the

Experimentally measured conversion efficiency spectra of the two fabricated NOS devices are in good agreement with the target curves.

1999 Avian Pathology  
Ten-day-old speci® c pathogen free (SPF) chickens were inoculated simultaneously with Eimeria acervulina and Newcastle disease virus (NDV). By employing immuno¯uorescent staining and in situ hybridization techniques, we detected NDV proteins and nucleic acids in different life stages of E. acervulina. However, no NDV particle was found within E. acervulina by electron microscopy. Oocysts from E. acervulina that contained NDV proteins and nucleic acids could elicit antibodies against NDV after

Moreover, the proportion of oocysts from chickens infected with E. acervulina and NDV which could be induced to sporulate in vitro was lower than those from chickens infected with E. acervulina alone. These results indicate that nucleic acids and proteins of NDV can exist within E. acervulina, and stimulate an immune response against NDV in chickens, and that NDV may also interfere with the sporulation of oocysts.

Regulation of coronaviral poly(A) tail length during infection is not coronavirus species- or host cell-specific

Jui-Hung Shien, Yi-Da Su, Hung-Yi Wu
2014 Virus genes  
It has been demonstrated that the length of the poly(A) tail in the bovine coronavirus (BCoV), which belongs to genus betacoronaviruses, is regulated throughout infection in human rectal tumor-18 (HRT-18) cells, and the length of the poly(A) tail is associated with the efficiency of virus translation. Here, we examined whether the regulation of viral poly(A) tail length is cell-type independent and whether it is a common feature of coronaviruses to assess the significance of the regulation. By

Interestingly, the poly(A) tail length variation was similarly found in the avirulent IBV strain H120 in CEK cells, although the overall poly(A) tail length was shorter for this virus. The results suggest that the regulation of coronaviral poly(A) tail length during infection may be a common feature among coronaviruses and can occur in a noncancerous cell line (BHK-21 cells), primary cell culture (CEK cells), and living system (chickens), further reinforcing the biological significance of this regulation during coronavirus infection.

Do resting brain dynamics predict oddball evoked-potential?

Tien-Wen Lee, Younger W-Y Yu, Hung-Chi Wu, Tai-Jui Chen
2011 BMC Neuroscience  
The oddball paradigm is widely applied to the investigation of cognitive function in neuroscience and in neuropsychiatry. Whether cortical oscillation in the resting state can predict the elicited oddball eventrelated potential (ERP) is still not clear. This study explored the relationship between resting electroencephalography (EEG) and oddball ERPs. The regional powers of 18 electrodes across delta, theta, alpha and beta frequencies were correlated with the amplitude and latency of N1, P2, N2
more » ... and P3 components of oddball ERPs. A multivariate analysis based on partial least squares (PLS) was applied to further examine the spatial pattern revealed by multiple correlations. Results: Higher synchronization in the resting state, especially at the alpha spectrum, is associated with higher neural responsiveness and faster neural propagation, as indicated by the higher amplitude change of N1/N2 and shorter latency of P2. None of the resting quantitative EEG indices predict P3 latency and amplitude. The PLS analysis confirms that the resting cortical dynamics which explains N1/N2 amplitude and P2 latency does not show regional specificity, indicating a global property of the brain. Conclusions: This study differs from previous approaches by relating dynamics in the resting state to neural responsiveness in the activation state. Our analyses suggest that the neural characteristics carried by resting brain dynamics modulate the earlier/automatic stage of target detection.
