Early studies had shown that metastatic lymph node (LN) was one of the most critical prognostic factors in gastric carcinoma (Hohenberger and Gretschel, 2003; Yokota et al, 2004; Dicken et al., 2005). Since the International Union Against Cancer tumor node metastasis (UICC TNM) classification for LN staging standard was modified in 1997, LN metastatic sites were replaced by the number of metast...

The synergistic effect of 18-crown-6 derivatives, such as 18-crown-6 (18C6), cis-dicyclohexano-18-crown-6 (DC18C6) and dibenzo-18-crown-6 (DB18C6), on the extraction of trivalent lanthanoids (Ln(3+)) into an ionic liquid, 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide, with 2-thenoyltrifluoroacetone (Htta) was investigated. The extractability of lighter Ln(3+) was enhanced by ad...

where X(t) = σB(t) + μt is BM with drift and S(0) = S0 > 0 is the intial value. We view S(t) as the price per share at time t of a risky asset such as stock. Taking logarithms yields back the BM; X(t) = ln(S(t)/S0) = ln(S(t))− ln(S0). ln(S(t)) = ln(S0) +X(t) is normal with mean μt + ln(S0), and variance σ2t; thus, for each t, S(t) has a lognormal distribution. As we will see in Section 1.4: let...

In this paper, we calculate the space ExtGL(n)(Ln(λ), Ln(μ)), where GL(n) is the general linear group of degree n over an algebraically closed field of positive characteristic, Ln(λ) and Ln(μ) are rational irreducible GL(n)-modules with highest weights λ and μ respectively, the restriction of Ln(λ) to any Levi subgroup of GL(n) is semisimple, λ is a p-restricted weight and μ does not strictly d...

A subset of natural killer (NK) cells in normal mouse lymph node (LN) expresses CD127 (IL-7 receptor-α chain) and is thought to derive from the thymus. However, CD127(+) NK cells are found in the LN of athymic mice. Therefore, the origin of CD127(+) NK cells in the LN is unclear. Here, we have identified unique NK-cell progenitors (NKPs) in the LN that express the pan-NK cell marker CD49b and C...

PURPOSE To calculate the frequency of lingual nerve (LN) damage caused by lower third molar extraction and describe the evolution of LN sensitivity as well as the prognosis of LN damage based on preoperative data. PATIENTS AND METHODS A retrospective study of 4,995 lower third molar extractions performed in 3,513 outpatients of the Department of Oral and Maxillofacial Surgery (University of B...

Lymph node (LN) metastasis is considered an important prognostic factor in patients with prostate cancer. The aim of this study was to determine the rate of LN metastasis among an Iranian population who underwent radical prostatectomy (RP) with pelvic LN dissection (PLND). In a retrospective review of medical records, 450 RP cases were included and the data on LN metastasis were extracted from ...

Lithium niobate (LN) microdisk resonators on a LN-silica-LN chip were fabricated using only conventional semiconductor fabrication processes. The quality factor of the LN resonator with a 39.6-μm radius and a 0.5-μm thickness is up to 1.19 × 10(6), which doubles the record of the quality factor 4.84 × 10(5) of LN resonators produced by microfabrication methods allowing batch production. Electro...

BACKGROUND MicroRNAs (miRNAs) are involved in the post-transcriptional regulation of genes. The objective of this study was to investigate whether select urinary cell-free microRNA's may serve as biomarkers in children with active lupus nephritis (LN) and to assess their relationship to the recently identified combinatorial urine biomarkers, a.k.a. the LN-Panel (neutrophil gelatinase associated...
