The objective of this study was to evaluate alterations in Pap smear, hybrid capture II (HCII), and visual inspection with acetic acid (VIA) in 684 women treated at a primary health care unit. The performance and agreement of the exams were evaluated. The study also described social, demographic, and reproductive factors and their association with uterine cervical lesions. Women had specimens t...

Rituximab, a monoclonal antibody directed against the B-lymphocyte antigen CD20, has shown promise in several autoimmune disorders. Pulmonary alveolar proteinosis (PAP) is an autoimmune disorder characterised by autoantibodies to granulocyte-macrophage colony-stimulating factor (GM-CSF). An open-label, proof-of-concept phase II clinical trial was conducted in 10 PAP patients. The intervention c...

In small mammals, muscles with shorter twitch contraction times and a predominance of fast-twitch, type II fibers exhibit greater posttetanic twitch force potentiation than muscles with longer twitch contraction times and a predominance of slow-twitch, type I fibers. In humans, the correlation between potentiation and fiber-type distribution has not been found consistently. In the present study...

Helper T cells (Th cells) play a central role in the initiation and maintenance of immune responses, including antitumor immunity. The ability of Th cells in murine models to maintain and enhance the cytolytic efficacy of CD8+ CTLs has led to a renewed interest in identifying human tumor antigens recognized by Th cells. Prostatic acid phosphatase (PAP) is a prostate cancer-associated tumor anti...

INTRODUCTION Increasing antibiotic resistance also has an impact on perioperative antibiotic prophylaxis (PAP). This narrative review evaluates fosfomycin trometamol (FT) as PAP in endourological interventions. MATERIALS AND METHODS Nine clinical studies including 4 randomized comparative studies were analyzed. A total of 1,614 patients received FT as PAP for different endourological procedur...

Purple acid phosphatases (PAPs), also known as type 5 acid phosphatases, are widely present in animals, plants, and fungi. In mammal, PAP was reported to participate in immune defense and bone resorption. In this study, the characteristics and potential functions of a PAP gene from pearl oyster Pinctada martensii (pm-PAP) were examined. The Pm-PAP cDNA was found to be 2777 base pairs, containin...

Endothelin-1 (ET-1) has been reported to induce pulmonary vasoconstriction via either ET(A) or ET(B) receptors, and vasorelaxation after ET-1 injection has been observed. Our study investigated the effects of ET-1 in isolated rabbit lungs, which were studied at basal tone (part I) and after preconstriction (U-46619; part II). Pulmonary arterial pressure (PAP) and lung weight gain were monitored...

A case of Pulmonary Alveolar Proteinosis (PAP), in association with tuberculosis, is described in a 35-year-old diabetic patient. Lung biopsy showed an intra-alveolar accumulation of PAS-positive material, and multifocal granulomas compatible with tuberculosis. The bronchoalveolar culture was positive for Mycobacterium tuberculosis. PAP results from an imbalance of the mechanisms that regulate ...

Background Elevated pulmonary artery pressures (PAP) from type II pulmonary hypertension (PH) is caused by a heterogeneous group of disorders. Myocardial fibrosis (MF) is a common pathological finding in many cardiovascular diseases; however its relationship with PAP is not well characterized. In particular, among patients with heart failure and preserved ejection fraction (HFpEF), MF may be a ...

Here we demonstrate a new regulatory mechanism for tRNA processing in Escherichia coli whereby RNase T and RNase PH, the two primary 3' → 5' exonucleases involved in the final step of 3'-end maturation, compete with poly(A) polymerase I (PAP I) for tRNA precursors in wild-type cells. In the absence of both RNase T and RNase PH, there is a >30-fold increase of PAP I-dependent poly(A) tails that ...
