INTRODUCTION Raynaud's phenomenon (RP) as a vasospastic response to cold and emotions has an impact on the quality of life. This also applies to patients with primary (idiopathic) RP. Moreover, RP may also be a factor of irreversible tissue injury manifested by ulceration or necrosis, especially in patients with connective tissue disease. Nailfold videocapillaroscopy (NVC) is a recognized metho...

This paper reviews the literature on reference pricing (RP) in pharmaceutical markets. The RP strategy for cost containment of expenditure on drugs is analyzed as part of the procurement mechanism. We review the existing literature and the state-of-the-art regarding RP by focusing on its economic effects. In particular, we consider: (1) the institutional context and problem-related factors whic...

INTRODUCTION Raynaud's phenomenon (RP) is a paroxysmal and recurrent acral ischemia resulting from an abnormal arterial vasospastic response to cold or emotional stress. Homocysteine, a sulphured amino acid, has been linked to cardiovascular and neurodegenerative diseases, diabetes, thrombosis, and bone fragility. Homocysteine has been also linked to the pathogenesis of RP, as increased serum h...

Ribosomal proteins are involved in many cellular processes through interactions with various RNAs. Here, applying the photoactivatable-ribonucleoside-enhanced cross-linking and immunoprecipitation approach to HEK293 cells overproducing ribosomal protein (rp) eS1, we determined the products of RNU5A-1 and RNU11 genes encoding U5 and U11 snRNAs as the RNA partners of ribosome-unbound rp eS1. U11 ...

Relapsing Polychondritis (RP) is an uncommon, chronic, and potentially life-threatening multisystem disorder characterized by recurrent inflammatory episodes affecting the cartilaginous tissues of the external ears, nose, peripheral joints, larynx and tracheobronchial tree, sometimes leading to their destruction. RP can also inflame other proteoglycan-rich structures, such as the eye, heart, bl...

This paper proposes an error-based segmentation approach for direct rapid prototyping (RP) of random cloud data. The objective is to fully integrate reverse engineering and RP for rapid product development. By constructing an intermediate point-based curve model (IPCM), a layer-based RP model is directly generated from the cloud data and served as the input to the RP machine for fabrication. In...

Reticulated platelets (RP) are newly-formed platelets with a greater mass, a residual amount of RNA and an increased prothrombotic potential. No studies investigating the association between RP and the risk of cardiovascular death in acute coronary syndrome (ACS) patients are available. In the frame of the AMI-Florence 2 study, we investigated RP in 229 (154 M/ 75 F) ACS patients (125 ST-elevat...

BACKGROUND Facial plastic surgeons may primarily focus on esthetic improvement of the nasal shape in patients seeking rhinoplasty (RP). However, medical conditions inside the nasal cavity should not be neglected because they may lead to unresolved sinonasal problems and, hence, dissatisfaction after esthetic RP. This observational study investigated the prevalence of sinonasal symptoms and end...

OBJECTIVES To compare the concordance of prostate cancer (PCa) laterality between the extended transperineal (TP) or transrectal (TR) prostate biopsy (BP) and radical prostatectomy (RP) specimens. To identify predictors of laterality agreement between BP and RP. MATERIALS AND METHODS Data from 533 consecutive patients with PCa (278 TP and 255 TR-diagnosed) treated with RP were analyzed. A 12-...

Neurological involvement in relapsing polychondritis (RP) is relatively rare. We describe the case of an 80-year-old man who presented with hypertrophic pachymeningitis (HP) together with arthritis as the first manifestation of RP. Auricular chondritis, which subsequently determined the diagnosis of RP, occurred a few weeks after the detection of HP. The neurological symptoms, as well as arthri...
