Recent studies suggest that androgen-driven alteration to the autocrine and paracrine factors produced by scalp dermal papilla (DP) cells may be a key to androgen-potentiated balding. Here, we screened dihydrotestosterone (DHT)-regulated genes in balding DP cells and found that dickkopf 1 (DKK-1) is one of the most upregulated genes. DKK-1 messenger RNA is(More)
Hypohidrotic ectodermal dysplasia (HED) is a very rare disease characterized by the virtual absence of eccrine glands, dry skin, scanty hair, and dental abnormalities. It is transmitted by an X-linked recessive gene or rarely an autosomal recessive gene. Therefore it is only males who fully express the condition. It is caused by mutations within the ED1(More)
PURPOSE To analyze the outcomes of laparoscopic liver resection compared with open liver resection in patients with hepatocellular carcinoma (HCC). METHODS Between July 2005 and December 2009, 26 consecutive patients with HCC underwent a pure laparoscopic liver resection, and data from this group (laparoscopic liver resection group, L-group) were compared(More)
To identify candidate genes that could be used as diagnostic and therapeutic targets for hepatocellular carcinoma (HCC), we searched for the genes that are overexpressed in HCC by combining representational difference analysis and microarray. Genes such as glypican-3 (GPC3), insulin-like growth factor 2, long-chain fatty-acid-coenzyme A ligase 4, farnesyl(More)
We have examined the frequency of SNP polymorphisms within the melanocortin-1 receptor (MC1R) and agouti signaling protein (ASIP) genes in 114 Korean vitiligo patients and 111 normal controls to assess the association of these loci with vitiligo risk. Using direct sequencing techniques, we found the following five MC1R coding region SNPs: Arg67Gln (G200A),(More)
Nonsurgical treatment has become the standard of care in hemodynamically stable patients with blunt liver trauma. The use of helical computed tomography (CT) in the diagnosis and management of blunt liver trauma is mainly responsible for the notable shift during the past decade from routine surgical to nonsurgical management of blunt liver injuries. CT is(More)
Intestinal obstruction is a common surgical emergency. Transmesenteric hernia is an unusual cause of bowel obstruction that may result in irreversible damage of the bowel and a fatal outcome. Once incarceration of the bowel occurs, strangulation and gangrene follow immediately. The mortality rate associated with this condition is about 15%, but in the(More)
PURPOSE To describe the clinical characteristics and outcomes after inguinal hernia repair in overweight and obese patients. METHODS We retrospectively reviewed the medical records of 636 adult patients who underwent mesh plug inguinal hernia repair performed by one surgeon from November 2001 to January 2009.The clinical characteristics and surgical(More)
The purpose of this study was to elucidate the prognostic factors for distal cholangiocarcinoma after curative resection, and to assess the significance of perineural invasion (PNI) and lymphovascular invasion (LVI) as prognostic factors. A retrospective analysis of 91 patients who underwent radical surgery for distal cholangiocarcinoma between March 2004(More)
BACKGROUND It is believed that the length of the actively growing phase of the anagen hair cycle mainly contributes to hair length. Recent studies showed that maintenance of β-catenin activity in the dermal papilla cells (DPCs) enables hair follicles to keep actively growing. Topical minoxidil treatment promotes hair growth in men with androgenetic(More)
