Application of Image Compression Ratio Analysis as a Method for Quantifying Complexity of Dental Enamel Microstructure.

It is well recognized that enamel microanatomy in mammals reflects biomechanical demands placed upon teeth, as determined by mechanical properties of species' diets, use of teeth as weapons, and so forth. However, there are limited options for researchers wishing to perform large-scale comparisons of enamel microstructure with adaptive questions in mind. This is because to date there has been no efficient method for quantification and statistical analysis of enamel complexity.

Facial Asymmetry in a Crying Newborn: A Comparison of Two Cases and Review of Literature.

Facial asymmetry in a crying newborn can be due to a variety of different causes. Neonatal asymmetric crying facies (NACF) is a specific phenotype, which is often underrecognized. It is defined as asymmetry of the mouth and lips with grimacing or smiling, but a symmetric appearance at rest.

On running for supervisor.

As reflection has become a firmly integrated element of good practice, and fundamental to the concept of learning from experience, individuals frequently utilise their own creativity and unique thought processes to make sense of their personal challenges. This paper uses the analogy of running a race to explore the personal challenge of undertaking preparation and study to become a supervisor of midwives (SoM), and to consider the unknown challenges ahead. This analogy gave rise to a unique and personal reflective cycle that incorporates traditional and familiar reflective models alongside acknowledgement of the physical and emotional advantages of physical exertion.

Early Vitamin K Deficiency Bleeding in a Neonate Associated with Maternal Acute Fatty Liver of Pregnancy.

Introduction Acute fatty liver of pregnancy (AFLP) is a rare but potentially fatal condition occurring in the third trimester or early postpartum period. It is characterized by microvesicular fatty infiltration of the liver. Clinically, the three most prominent derangements in women with AFLP are hepatic dysfunction, renal insufficiency, and impaired coagulation.

Research preparedness paves the way to respond to pandemic H1N1 2009 influenza virus.

The international community has been preparing for an influenza pandemic because of the threat posed by H5N1 avian influenza. Over the past several years, Canada has dedicated funding to boost capacity for research, and public health and health care system readiness and response in the event of a pandemic. The current H1N1/09 influenza pandemic is now testing our readiness.

Effect of semen on vaginal fluid cytokines and secretory leukocyte protease inhibitor.

Unlabelled: The presence of semen in vaginal fluid, as identified by an acid phosphatase spot test, does not influence vaginal proinflammatory cytokine concentrations.

Objective: Determine whether semen, as detected by acid phosphatase, influences vaginal cytokines or secretory leukocyte protease inhibitor concentrations.

Methods: 138 pregnant women had vaginal fluid collected for Gram stain, acid phosphatase detection by colorimetric assay, and interleukin 1-Beta, interleukin-6, interleukin-8, and secretory leukocyte protease inhibitor measurement by enzyme immunoassay.

Trial results of a new combination therapy for myeloid leukaemia.

Chronic myeloid leukaemia is a condition that affects around 600 people a year in the UK. The only curative intervention to date has been bone-marrow transplantation. A combined drug therapy featuring interferon and a new drug called imatinib has shown encouraging results in recent trials.

Effect of combination antiretroviral therapy on cerebrospinal fluid HIV RNA, HIV resistance, and clinical manifestations of encephalopathy.

Objectives: This study evaluated the effect of treatment with abacavir/lamivudine/zidovudine versus lamivudine/zidovudine on cerebrospinal fluid (CSF) human immunodeficiency virus (HIV) RNA and clinical manifestations of HIV encephalopathy in children.

Study Design: HIV-infected children 7 months to 10 years of age (n = 23) were studied. CSF and plasma were obtained at baseline and weeks 8, 16, and 48.
