Macular Pigment Optical Density as a Measurable Modifiable Clinical Biomarker.

Background: Carotenoids are present throughout retina and body its dense deposition leads to an identifiable yellow spot in the macula. Macular pigment optical density (MPOD) measured in the macula is vital to macular well-being and high-resolution visual acuity. MPOD has also been associated with various health and disease states.

Knowledge of dental enamel defects amongst undergraduate dental students-a cross-sectional survey.

Introduction/objectives: Enamel defects are disturbances in the quantity or quality of enamel, due to disruption or damage to the enamel organ during amelogenesis. The correct diagnosis of enamel defects is critical as diverse management options could be required for different conditions. Difficulties in diagnosis can happen, because these defects may have similar clinical presentations.

Association of overlap syndrome with incident atrial fibrillation.

Increasingly compelling data link chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) to cardiovascular complications independent of known comorbidities. It remains unclear whether the association is amplified in the presence of both conditions. The aims of this study are to assess the prevalence of atrial fibrillation (AF) in overlap syndrome (OS) and to identify risk factors predisposing to this atrial arrhythmia.

Identification of differentially expressed genes in Malus domestica after application of the non-pathogenic bacterium Pseudomonas fluorescens Bk3 to the phyllosphere.

Biological control of plant diseases by the application of antagonistic micro-organisms to the plant phyllosphere is only marginally understood. Suppression subtractive hybridization (SSH) was used for the identification of genes expressed after application of the non-pathogenic bacterium Pseudomonas fluorescens Bk3 to the phyllosphere of the apple scab-susceptible cultivar Malus domestica cv. Holsteiner Cox.

Isolated digital gangrene complicating hepatitis a infection in a child.

Hepatitis A virus is rarely associated with extrahepatic complications. A child presented with a history suggesting Raynaud's phenomenon and severe digital gangrene, as a complication of hepatitis A infection. Coagulation study results (protein C, protein S, antithrombin III, and activated protein C resistance) were all normal except for anticardiolipin antibodies, which were present on initial presentation and resolved later.

Expression of the interferon-induced Mx proteins in biliary atresia.

Biliary atresia (BA) is a rare disease of the newborn for which the Kasai procedure is curative only for a few of the patients. The dilemma is that all therapeutic attempts to cure the disease are symptomatic because the etiology is still unclear. One theory suggests a progressive inflammatory process, possibly induced by a viral infection.

Characterization by suppression subtractive hybridization of transcripts that are differentially expressed in leaves of apple scab-resistant and susceptible cultivars of Malus domestica.

In order to compare transcription profiles in cultivars of Malus domestica that are differentially sensitive to apple scab (Venturia inaequalis), two cDNA libraries were constructed using the suppression subtractive hybridization (SSH) method. Subtraction hybridization was performed between cDNAs from uninfected young leaves of the resistant cultivar Remo and the susceptible Elstar. In total, 480 EST clones were obtained: 218 (ELSTAR) clones represent transcripts that are preferentially expressed in Elstar, while the other 262 (REMO) are derived from RNAs that are more highly expressed in Remo.

Anticardiolipin antibodies in patients with retinal vein occlusion and no risk factors: a prospective study.

Background: Several reports have described the association between antiphospholipid antibodies (APAs) and retinal venous occlusive (RVO) disease. The purpose of this study was to look at the prevalence of these antibodies in patients with RVO disease and no conventional risk factors. We specifically examined how APAs may affect the course of this disease.
