Abnormal signaling of the protein kinase Akt has been shown to contribute to human diseases such as diabetes and cancer, but Akt has proven to be a challenging target for drugging. Using iterative in situ click chemistry, we recently developed multiple protein-catalyzed capture (PCC) agents that allosterically modulate Akt enzymatic activity in a protein-based assay. Here, we utilize similar PC...

The differential display of mRNA is a new strategy to identify genes that are differentially expressed under altered conditions. We applied this method to determine differential gene expression in the rat pheochromocytoma cell line during differentiation induced by nerve growth factor (NGF). Three different mRNA species were isolated, and their differential expression was confirmed by RT-PCR. O...

Pheochromocytomas are rare catecholamine-secreting neuroendocrine tumors arising from chromaffin cells in the adrenal medulla. Typical classic triad are consisted of headaches, palpitations, and profuse diaphoresis. But some patients with pheochromocytomas have other cardiovascular manifestations such as left ventricular hypertrophy, congestive heart failure, and cardiac arrhythmia. Rarely, phe...

Multilabel learning is an extension of binary classification that is both challenging and practically important. Recently, a method for multilabel learning called probabilistic classifier chains (PCCs) was proposed with numerous appealing properties, such as conceptual simplicity, flexibility, and theoretical justification. However, PCCs suffer from the computational issue of having inference t...

Coherent configurations (CCs) are highly regular colorings of the set of ordered pairs of a “vertex set”; each color represents a “constituent digraph.” CCs arise in the study of permutation groups, combinatorial structures such as partially balanced designs, and the graph isomorphism problem; their history goes back to Schur in the 1930s. A CC is primitive (PCC) if all its constituent digraphs...

UNLABELLED Pheochromocytomas are rare tumors arising from chromaffin cells of the sympathoadrenal system and 85% of them are located in the adrenal medulla. Malignant pheochromocytomas account for 10% of all pheochromocytomas. Since clinical, biochemical and histopathological features can not reliably distinguish malignant from benign tumors, malignancy is established in the presence of distant...

The expression of the neuropeptide Y (NPY) gene varies considerably in human pheochromocytomas, but the mechanisms for this variation have not been clarified. To investigate the regulation pattern of the NPY gene in human pheochromocytomas, we screened 16 pheochromocytomas and 9 normal adrenal tissues with Northern blots. The expression level of NPY mRNA in normal adrenal medulla was low and re...

OBJECTIVE To analyse the variation between primary care centres (PCCs) with regard to prescribing antibiotics and to investigate whether the variation can be explained by factors related to patient satisfaction and to socio-demographic characteristics of the populations in the catchment areas of the PCCs. METHODS The frequency of prescription of antibiotics by GPs at the PCCs was used as the ...

Pancreatic stellate cells (PSC), which are implicated in desmoplasia in pancreatic cancer, enhance the malignancy of cancer cells and confer resistance to established treatments. We investigated whether the antifibrotic agent pirfenidone can suppress desmoplasia and exert antitumor effects against pancreatic cancer. Primary PSCs were established from pancreatic cancer tissue obtained during sur...

We would treat with 4-factor PCCs because otherwise—with an INR of 1.9—there is a high risk of further expansion of an already large ICH. Without reversal of the anticoagulant effects of warfarin, the patient’s life is at stake. At age 65 years, he has a reasonable chance to recover from a right-sided ICH if treated early and aggressively. In our eyes, early withdrawal of care is not an option!...
