Lymphoid cells play a critical role in the immune system, which includes three subgroups of T, B, and NK cells. Recognition of the complexity of the human genetics transcriptome in lymphopoiesis has revolutionized our understanding of the regulatory potential of RNA in normal lymphopoiesis and lymphoid malignancies. Long non-coding RNAs (lncRNAs) are a class of RNA molecules greater than 200 nucleotides in length.

Objective: To investigate the effect of a tooth whitening agent on surface roughness, surface hardness, and force delivery properties of polyethylene terephthalate glycol (PETG) thermoplastic retainer materials of two different thicknesses.

Methods: PETG sheets (1 mm and 1.5 mm) were thermoformed over a 30 × 60 × 10 mm rectangular stone model.

Background: Over the past two decades, there has been mounting evidence that primary anastomosis (PA) is a safe alternative to Hartmann's procedure (HP) in acute diverticulitis. In addition, specialized colorectal surgeons are more likely to perform PA. This study aimed to analyse if this evidence has led to an increase in the rate of PA in a major tertiary institution over time.

Introduction: Residual subclinical synovitis can still be present in joints of rheumatoid arthritis (RA) patients despite clinical remission and has been linked to ongoing radiological damage. The aim of the present study was to assess subclinical synovitis by positron emission tomography (PET; macrophage tracer (11)C-(R)-PK11195) in early RA patients with minimal disease activity without clinically apparent synovitis (MDA); and its relationship with clinical outcome and magnetic resonance imaging (MRI), respectively.

Methods: Baseline PET and MRI of hands/wrists were performed in 25 early MDA RA patients (DAS 44 < 1.

Objective: To determine whether macrophage targeting by (R)-11C-PK11195 positron emission tomography (PET) can visualize subclinical joint inflammation in patients with rheumatoid arthritis (RA) without clinical arthritis during or after treatment, with flare as clinical outcome measure.

Methods: (R)-11C-PK11195 PET and contrast-enhanced magnetic resonance imaging (MRI) of hands/wrists were performed in 29 patients with RA without clinical arthritis. (R)-11C-PK11195 PET uptake (semiquantitative score 0-3) in metacarpophalangeal, proximal interphalangeal, and wrist joints (i.

The most common cause of malignant hypertension in children is renal or renovascular pathology. The combination with lethargy suggests a diagnosis of hypertensive crisis with hypertensive encephalopathy. Here, we present a case of severe hypertension with lethargy as the sole presenting symptoms of ileocecal intussusception.

Background: The purpose of this study was to determine whether the disease-free interval (DFI) between treatment of primary head and neck cutaneous squamous cell carcinoma (SCC) and the development of regional metastases is an independent prognostic factor.

Methods: A retrospective analysis of 229 patients with metastatic nodal head and neck cutaneous SCC, treated with curative intent by surgery ± adjuvant radiotherapy was conducted.

Results: After adjusting for the effect of nodal staging, extracapsular spread, involved margins, adjuvant radiotherapy, and immunosuppression, a short DFI (≤9 months vs >9 months) was a significant predictor of disease-related mortality (hazard ratio [HR], 3.
