In nineteenth century Great Britain, Thomas Henry Huxley [3] proposed connections between the development of organisms and their evolutionary histories, critiqued previously held concepts of homology, and promoted Charles Darwin?s theory of evolution [4]. Many called him Darwin?s Bulldog. Huxley helped professionalize and redefine British science. He wrote about philosophy, religion, and social...

The 5,10-methylenetetrahydrofolate reductase (MTHFR) gene plays a critical role in folate metabolism. Studies on the association between MTHFR polymorphisms and length changes in short tandem repeat DNA sequences [microsatellite instability (MSI)] are inconsistent. Using data from colon cancer cases (n=503) enrolled as part of an existing population-based case-control study, we investigated the...

Proof. First suppose that a ∼H b, so that a = bk for some k ∈ H, and let ah (with h ∈ H) be an artibrary element of aH. Then we have ah = bkh = b(kh) ∈ bH, hence aH ⊆ bH. The proof of bH ⊆ aH is similar. Conversely, suppose that aH = bH. Since a ∈ aH = bH we have a = bk for some k ∈ H. Then a−1b = k−1 ∈ H, hence a ∼H b. (d) Prove that the map g 7→ ag is a bijection from H to aH. Proof. Consider...

PURPOSE To analyze the anatomic consequences of selective amygdalohippocampectomy (AH) in patients with hippocampal sclerosis and to correlate the clinical outcome with the MR appearance. METHODS Seventeen patients were examined with clinical and neuropsychologic examination and cranial MR after AH (7 transcortical AH, 10 trans-Sylvian AH). The clinical and neuropsychologic outcomes after AH ...

A History ofMedicine in South Carolina, 1825-1900, by JOSEPH I. WARING, Charleston, South Carolina Medical Association, 1967, pp. xv, 366, illus., $7.70. In this second volume Waring has continued the history of South Carolina from the graduation in 1825 of the first class at the Medical College. He deals separately with plantation medicine, the growth of hospitals, medical education, professio...

OBJECTIVE The 677 C>T and 1298 A>C polymorphisms of methylenetetrahydrofolate reductase (MTHFR) gene have been widely reported and considered to have a significant effect on breast cancer risk, but the results are inconsistent. A meta-analysis based on 57 eligible studies was carried out to clarify the role of MTHFR gene polymorphisms in breast cancer. METHODS AND RESULTS Eligible articles we...

The syndrome of enhanced atrioventricular nodal (AVN) conduction has been defined arbitrarily by: AH interval during normal sinus rhythm (AH-NSR) less than or equal to 60 msec; shortest right atrial pacing cycle length (PCL) maintaining 1:1 AVN conduction (shortest PCL 1:1) less than or equal to 300 msec; and at the shortest PCL 1:1, an increase in the AH interval from AH-NSR (delta AH) less th...
