This study determined the effect of cleansing solutions on microtensile bond strengths of self-etch adhesives to saliva-contaminated dentin. Seventy five human molars were ground flat to expose mid-depth dentin, and randomly assigned to 5 groups (n=15): no contamination, saliva contamination without cleansing, saliva and cleansing with water, saliva and cleansing with 2% chlorhexidine, and sali...

TOPIC: Diffuse Lung Disease TYPE: Original Investigations PURPOSE: Idiopathic Pulmonary Fibrosis (IPF) is considered a disease of unknown etiology with varying incidence among populations and geographies. This study aimed to assess the risk factors IPF Pakistani population. METHODS: A gender age matched case-control was conducted. Adult cases IPF, were defined on criteria by Indian Chest Regist...

Background: Intertrochanteric fractures are one of the most common fractures encountered in our practice. Most of them need operative intervention and union is achieved. As per the literature dynamic hip screw (DHS) is the gold standard for the treatment of these fractures, however problem arises with maintenance of neck shaft angle and proper reduction in unstable intertrochanteric fractures. ...

We propose construction of a unique and definite metric (η +), time-reversal operator (T) and an inner product such that the pseudo-Hermitian matrix Hamiltonians are C, PT, CPT invariant and PT(CPT)-norm is indefinite (definite). Here, P and C denote the generalized symmetries : parity and charge-conjugation respectively. The limitations of the other current approaches have been brought out.

Background: Thalassemia major (TM) is a severe disease and the most common anemia worldwide. The survival time of the disease and its risk factors are of importance for physicians. The present study was conducted to apply the semi-parametric Cox PH model and use parametric proportional hazards (PH) and accelerated failure time (AFT) models to identify the risk factors related to survival of TM ...

Background: Liver kinase B1 (LKB1) is known as a tumor suppressor gene and also inhibits reactive oxygen species (ROS) levels. Intracellular ROS are catalyzed by the enzyme complex nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX). We previously reported that NOX4 induced migration invasion of fibroblast-like synoviocytes (FLS) in rheumatoid arthritis (RA). Although LKB1 expecte...

TOPIC: Diffuse Lung Disease TYPE: Original Investigations PURPOSE: Previously, it was thought that the risk factors lead to development of Idiopathic Pulmonary Fibrosis (IPF) were environmental or occupational in nature. However, recent studies have shown disease has a strong underlying genetic component. The objective this review identify polymorphisms associated with developing IPF. METHODS: ...
