The value of replantation of parts of the upper limb is well established and replantation of a digit has now be come a standard procedure. However, there are few reports of replantation of hand amputated through the palmar arch level. We have reviewed 14 cases of 14 patients replantation of hand amputated through the arterial palmar arch level from Mar. 1976 through Mar. 1982. The success rate in our series is 64 percent. This is slightly lower than the other levels due to its anatomical complexity. According to the anatomical complexity and distribution of nerves and vessels, it is divided to three levels. In level A, the superficial palmar arch and/or the deep palmar arch should be repaired. In level B, the princeps pollicis artery should be repaired after anastomosis of the superficial and deep palmar arch. In level C, each common palmar digital artery should be repaired but if it is impossible to repair of all fingers, replantation of thumb and index should be performed as possible. Meticulous microsurgical technique and precise anatomical knowledge is mandatory for replantation of the palmar arch level.

Deep cerebral venous thrombosis is a rare condition associated with edema, infarction or hemorrhage in basal ganglia, thalamus and periventricular white matter. It presents nonspecific clinical manifestations such as altered consciousness, headache, focal neurological deficit, nausea and vomiting. Extrapyramidal signs are very rare in deep cerebral venous thrombosis. We report a patient who presented micrographia, hypophonia and bradykinesia as an early manifestation of deep cerebral venous thrombosis.

Hippo/YAP signaling is implicated in tumorigenesis and progression of various cancers. By inhibiting a plethora signaling cascades, resveratrol has strong anti-tumorigenic and anti-metastatic activity. In the present study, we demonstrate that resveratrol decreases the expression of YAP target genes. In addition, our data showed that resveratrol attenuates breast cancer cell invasion through the activation of Lats1 and consequent inactivation of YAP. Strikingly, we also demonstrate that resveratrol inactivates RhoA, leading to the activation of Lats1 and induction of YAP phosphorylation. Further, resveratrol in combination with other agents that inactivate RhoA or YAP showed more marked suppression of breast cancer cell invasion compared with single treatment. Collectively, these findings indicate the beneficial effects of resveratrol on breast cancer patients by suppressing the RhoA/Lats1/YAP signaling axis and subsequently inhibiting breast cancer cell invasion.

The small GTP-binding protein Rab25 is associated with tumor formation and progression. However, recent studies have shown discordant effects of Rab25 on cancer cell progression depending on cell lineage. In the present study, we elucidate the underlying mechanisms by which Rab25 induces cellular invasion. We demonstrate that Rab25 increases β1 integrin levels and subsequent activation of EGFR and upregulation of VEGF-A expression, leading to increased Snail expression, epithelial-to-mesenchymal transition and cancer cell invasiveness. Strikingly, we identify that Snail mediates Rab25-induced cancer cell invasiveness through fascin expression and that ectopic expression of Rab25 aggravates metastasis of ovarian cancer cells to the lung. We thus demonstrate a novel role of a β1 integrin/EGFR/VEGF-A/Snail signaling cascade in Rab25-induced cancer cell aggressiveness through induction of fascin expression, thus providing novel biomarkers and potential therapeutic targets for Rab25-expressing cancer cells.

BACKGROUND: In vitro measurement of allergen-specific IgE has become an important part of allergy diagnoses. HYTEC 288 system (Hycor Biomedical Inc., USA), which was recently introduced in Korea, is a fully automated immunoassay for quantitative measurements of allergen-specific IgE. In this study, we compared the clinical utility of this in vitro allergy test with that of ImmunoCAP assay (ImmunoDiagnostics, Sweden). METHODS: To evaluate the reproducibility of HYTEC 288 system, 50 serum samples were tested in duplicate each for Dermatophagoides pteronyssinus (d1) and D. farinae (d2) specific IgE. To assess the agreement between ImmunoCAP and HYTEC 288 assays, 56 serum samples were tested for the other 21 allergen-specific IgE. RESULTS: No significant differences within the range of quantitative analysis were observed between HYTEC 288 and ImmunoCAP assays for d1 and d2 (P=0.65 and 0.55, respectively). The agreements of HYTEC allergen-specific IgE assay with ImmunoCAP within +/-1 class grade were 80% and 100% for d1 and d2, respectively. The correlation coefficients between HYTEC 288 and ImmunoCAP results within the range of quantitative analysis were overally 0.90, regardless of allergen, for d1 and d2 specific IgE, 0.91 and 0.98, respectively. Running times for the HYTEC 288 and Phardia 100 were 5.5 and 4.6 min per test, respectively. CONCLUSIONS: Hycor HYTEC 288 showed a favorable agreement with ImmunoCAP and can be used for fully automated quantitative measurements of allergen-specific IgE in the clinical laboratory.

OBJECTIVE: The present study was performed to investigate the efficiency of partial laser assisted hatching (p-LAH; lased 1/2 ZP width from ZP edge) on hatching of mouse blastocysts. METHODS: We used non-contact 1.48 micrometer diode laser (MTM, Switzland) to create a precise hole on zona pellucida. 2-cell embryos were collected from the mouse (ICR) oviduct at 48 hours after hCG administration. Collected 2-cell embryos were cultured in the P-1 medium supplemented with 0.4% BSA. For experiments, embryos at 8-cell stage were used after 20~22 hours in culture. After conventional (c-LAH) or partial laser assisted hatching, the embryos were further cultured in P-1 medium supplemented with 0.4% BSA for 3 days. To compare efficiency of complete and partial laser assisted hatching, hatching rate, hatching time and blastocyst diameter and zona pellucida thickness at hatching time were investigated. Embryos were examined every 12 hours. Blastocyst diameter and zona pellucida thickness at hatching time were measured with an ocular micrometer. RESULTS: Hatching rates of p-LAH group (84.2%) was significantly higher than that of control group (39.3%), but there was no difference between the p-LAH (84.2%) and c-LAH (91.2%). p-LAH group was hatched 12 hours earlier than control group, but hatched 12 hours later than c-LAH group. The diameter of blastocyst at hatching time of p-LAH group (113.1+/-6.4 micrometer) was smaller than that of control group (122.2+/-5.0 micrometer), but larger than that of c-LAH group (102.2+/-2.7 micrometer). Zona pellucida thickness at hatching time of p-LAH group (6.4+/-0.9 micrometer) was thicker than that of control group (4.5+/-1.5 micrometer), but thinner than that of c-LAH group (10.0+/-0.8 micrometer). CONCLUSION: These results suggest that p-LAH may maintains the cell arrangement of early embryos to ensure successful development and prevent precocious hatching of blastocyst when compare to c-LAH and conventional (acidic tyrode) AH. Thus, p-LAH may provide a valuable and effective AH technique for human ART program.
