PURPOSE Little information is available regarding the use of patient-controlled sedation (PCS) among elderly patients undergoing operative procedures under local or regional anaesthesia. This prospective, randomized study evaluated the safety of propofol PCS, and the attitude among elderly patients toward self-administration of sedation during cataract surgery. METHODS Prospective, randomized...

Although oral sensory feedback is essential for mastication, whether the cortical activity elicited by oral stimulation is associated with the preferred chewing side (PCS) is unclear. Somatosensory evoked fields were measured in 12 healthy volunteers (6 with the right side as the PCS and 6 with the left side as the PCS) following tongue and hard palate stimulation. Three components were identif...

BACKGROUND There are less data on the clinical and diagnostic imaging characteristics, management, and outcomes of patients with previous cardiac surgery (PCS) presenting with acute type A aortic dissection (AAD). METHODS AND RESULTS In 617 patients with AAD, we evaluated the differences in the clinical characteristics, management, and in-hospital outcomes of the cohorts with and without PCS....

Plasma cells (PCs) have a heterogeneous phenotype in humans. While bone marrow PCs are CD20-CD138+, tonsil PCs are CD20+CD138+/- and peripheral plasmablasts (PBs) are CD20-CD138-. In vitro, PCs are mainly generated by the activation of CD27+ memory B-cells through transient stimulation of CD40, and their phenotype appears similar to that of bone marrow PCs. While CD20 expression is lost at the ...

Background Pain catastrophizing is an exaggerated negative cognitive response related to pain. It is commonly assessed using the Pain Catastrophizing Scale (PCS). Translation and validation of the scale in a new language would facilitate cross-cultural comparisons of the role that pain catastrophizing plays in patient function. Purpose The aim of this study was to translate and culturally ada...

CONTEXT Personal care services (PCS) are intended to enable beneficiaries with physical or cognitive impairments to live safely at home rather than in nursing facilities. The quality and flexibility of these services, typically provided by home care agencies, may not be sufficient to allow some beneficiaries to continue living at home. OBJECTIVE We sought to test whether consumer direction of...

introduction: detection of caries lesions on approximal surfaces of posterior teeth is difficult, since wide contact points hamper direct visual inspection. due to the importance of the early detection of dental caries, the aim of this study is to compare the performance of different methods (visual, bitewing radiography and diagnodent) in detecting approximal caries in primary molars. methods:...

we introduce a new concept of general $g$-$eta$-monotone operator generalizing the general $(h,eta)$-monotone operator cite{arvar2, arvar1}, general $h-$ monotone operator cite{xiahuang} in banach spaces, and also generalizing $g$-$eta$-monotone operator cite{zhang}, $(a, eta)$-monotone operator cite{verma2}, $a$-monotone operator cite{verma0}, $(h, eta)$-monotone operator cite{fanghuang}, $h$-...

The spindle assembly checkpoint (SAC) is a surveillance mechanism of faithful chromosome segregation during mitosis. Budding uninhibited by benzimidazole-related-1 (BubR1) plays a central role in the SAC through inhibition of anaphase promoting complex/cyclosome (APC/C) activity until all chromosomes have established proper attachment to the mitotic spindle. Loss-of-function mutations in the BU...

abstract a solitary plasmacytoma of bone occurs in approximately 2-5% of patients with myeloma. the lesion mostly found in the axial skeleton and have infrequently been reported to arise in the hand, and usually occur in the distal phalanges. we report the interesting case of a 75-year-old man who developed a solitary lytic lesion of the thumb proximal phalanx. this lesion was explored through ...
