Yeast cells modulate their protein synthesis capacity in response to physiological needs through the transcriptional control of ribosomal protein (RP) genes. Here we demonstrate that the transcription factor Sfp1, previously shown to play a role in the control of cell size, regulates RP gene expression in response to nutrients and stress. Under optimal growth conditions, Sfp1 is localized to th...

Four peroxidase components, named RP-2, 4, 6, and 7, were isolated from rice (Oryza sativa L.) green leaves. Isoelectric focusing indicated that each preparation was homogeneous. The molecular weights of RP-2, 4, 6, and 7 estimated by SDS-PAGE were 48,000, 48,000, 40,000, and 39,500, and their isoelectric points were 5.4, 8.1, 9.3, and 9.2, respectively. The activity of every preparation was ma...

Retinitis pigmentosa (RP) is a progressive inherited retinal disease characterized by nyctalopia, visual field constriction, and reduced full-field electroretinograms. The progressive loss of photoreceptors leads to vision loss at the end stage of RP. The prevalence of RP is approximately 1/4,000. Since it is one of the major causes of visual impairment worldwide, morphological and functional a...

BACKGROUND Relapsing polychondritis (RP) is associated with other rheumatic or autoimmune disease in about 30% of cases; however, an association with malignancy is rare with the exception of myelodysplastic syndrome (MDS). Observation Herein we report the first case, to our knowledge, of RP following splenic non-Hodgkin lymphoma (NHL), and we have reviewed all the previous well-documented repor...

A B S T R A C T Introduction: Diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. Due to anti-diabetic and antioxidant activity of Rumex patientia (RP), this research study was conducted to evaluate the efficacy of chronic Rumex patientia feeding on alleviation of learning and memory disturbance in streptozo...

BACKGROUND To report the predictive value of nail-fold capillaroscopy (NFC) patterns of vasculopathy for systemic sclerosis (Scleroderma; SSc) in an unselected cohort of patients with Raynaud's phenomenon (RP). METHODS Patients referred to a tertiary SSc clinic with RP were evaluated by light/video-NFC. Clinical diagnosis, details and serology were recorded. Primary RP was defined as RP with ...

Retinitis pigmentosa (RP) encompasses a group of inherited retinal dystrophies characterized by the primary degeneration of rod and cone photoreceptors. RP is a leading cause of visual disability, with a worldwide prevalence of 1:4000. Although the majority of RP cases are non-syndromic, 20-30% of patients with RP also have an associated non-ocular condition. RP typically manifests with night b...

Reticulated platelets (RP) are young platelets that contain residual RNA, and measurement of RP has been to assess thrombopoiesis. In the present study, flow cytometric counts of RP were compared using paired specimens elicited from dogs with various platelet counts by different RP collection procedures, the whole blood method (WBM) and platelet rich plasma method (PRPM). The flow cytometric co...
