Pheochromocytomas (PCCs) are slow-growing neuroendocrine tumors arising from adrenal chromaffin cells. Tumors arising from extra-adrenal chromaffin cells are called paragangliomas. Metastases can occur up to approximately 60% or even more in specific subgroups of patients. There are still no well-established and clinically accepted "metastatic" markers available to determine whether a primary t...

BACKGROUND Fluid resuscitation following traumatic injury causes haemodilution and can contribute to coagulopathy. Coagulation factor replacement may be necessary to prevent bleeding complications of dilutional coagulopathy. Compared with fresh frozen plasma (FFP), prothrombin complex concentrate (PCC) may potentially offer a more rapid and effective means of normalizing coagulation factor leve...

Pheochromocytoma (PCC) is related to germline mutations in 12 susceptibility genes. Although comparative genomic hybridization array has revealed some putative tumor suppressor genes on the short arm of chromosome 1 that are likely to be involved in PCC tumorigenesis, the molecules involved, except for those encoded by known susceptibility genes, have not been found in the generation of sporadi...

In a retrospective study of bleeding patients in cardiac surgery, Cappabianca et al. [1] observed that the use of prothrombin complex concentrate (PCC) compared with fresh-frozen plasma (FFP) was associated with a higher risk of postoperative renal complications. In the unadjusted comparison, acute kidney injury (AKI) incidence was significantly higher in the PCC group, and use of PCC was an in...

2. Formal caregivers associated PCC with positive and empathic feelings, and believed it to be in line with their professional ethics, principles, and organisational vision, mission, and values. However, ambivalent feelings were recorded when formal caregivers encountered difficulties in practising PCC. Formal caregivers reported good practices in providing daily care that aligned with PCC prin...

BACKGROUND To maximise the potential for reducing the risk of adverse pregnancy outcomes, preconception counselling (PCC) is used to inform couples contemplating pregnancy about general and personal risk factors. Many initiatives have been developed to provide PCC, but none offers it routinely in a presumed low-risk population. The objective of the study was to investigate the extent to which w...

Background and study aims  Endoscopic submucosal dissection (ESD) is useful for en bloc resection of superficial colorectal neoplasms to ensure accurate histologic diagnoses. However, colorectal ESD is associated with a high frequency of adverse events (AEs). We aimed to investigate the effectiveness of prophylactic clip closure (PCC) of mucosal defects for AEs after colorectal ESD. Patients ...

Polynomial cancellation coding (PCC) is a very effective technique that reduces the sensitivity of orthogonal frequency division multiplexing (OFDM) to frequency errors at the cost of reduced spectral efficiency. This paper investigates the effect of PCC on the fading characteristics of multipath channels and on the error performance OFDM in a two-path fading channels. Channel coding is employe...

OBJECTIVES Clinicians often need to rapidly reverse vitamin K antagonists (VKAs) in the setting of major hemorrhage or urgent need for surgery. Little is known about the safety profile of the traditional reversal agent, plasma, or the newly approved agent, four-factor prothrombin complex concentrate (4F-PCC), in a randomized setting. This is an integrated analysis of safety data from two clinic...

BACKGROUND Oxygenic photosynthetic microorganisms such as cyanobacteria and microalgae have attracted attention as an alternative carbon source for the next generation of biofuels. Glycogen abundantly accumulated in cyanobacteria is a promising feedstock which can be converted to ethanol through saccharification and fermentation processes. In addition, the utilization of marine cyanobacteria as...
