Gastric cancer complicated with hemophagocytic lymphohistiocytosis: case report and a brief review.

Hemophagocytic lymphohistiocytosis (HLH) comprises a group of severe immune function disorders that can lead to immune-mediated organ damage. There are two subtypes of HLH: primary and secondary. Secondary HLH is associated with infectious, oncologic, chemotherapeutic, and other underlying causes, and studies on HLH triggered by tumors have mainly focused on hematological malignancies.

Identifying a Safe Range of Stimulation Current for Intraoperative Neuromonitoring of the Recurrent Laryngeal Nerve: Results from a Canine Model.

Background: Intraoperative neuromonitoring (IONM) of the recurrent laryngeal nerve (RLN) has been widely applied during thyroid surgery. However, the safe range of stimulation intensity for IONM remains undetermined.

Methods: Total thyroidectomies were performed on twenty dogs, and their RLNs were stimulated with a current of 5-20 mA (step-wise in 5 mA increments) for 1 min.

Significant differences in the clinicopathological characteristics and survival of gastric cancer patients from two cancer centers in china and Korea.

Purpose: To compare the clinicopathological data and long-term survival of gastric cancer patients in China and Korea.

Materials And Methods: Patients who had undergone gastrectomy for gastric cancer between 1998 and 2009 in 2 high-volume institutions in both China (n=1,637) and Korea (n=2,231) were retrospectively evaluated. Clinicopathological variables, overall survival (OS), progression-free survival (PFS), and surgery-related complications were assessed for all patients and compared between the 2 institutions.

Heterodinuclear M(II)-Ln(III) single molecule magnets constructed from exchange-coupled single ion magnets.

The synthesis and characterization of four dinuclear 3d-4f complexes [M(II)Ln(III)(L)(DBM)3] (ZnDy = 1, CoY = 2, CoDy = 3·3.5CH3CN, CoGd = 4·3.5CH3CN) are reported (H2L = N,N'-dimethyl-N,N'-(2-hydroxy-3-methoxy-5-methyl-benzyl)ethylenediamine, DBM(-) = anion of 1,3-diphenyl-propane-1,3-dione).

Synthesis, crystal structure and magnetic properties of dinuclear NiIILnIII complexes based on a flexible polydentate ligand.

The synthesis and characterization of three isomorphous complexes [NiII(L)LnIII(DBM)₃] (Ln = Gd (1·2.5CH₃CN·0.5H₂O), Tb (2·2CH₃CN·0.

Supramolecular lanthanide metallogrids exhibiting field-induced single-ion magnetic behavior.

A supramolecular strategy has been applied to construct two tetranuclear lanthanide complexes for investigating the magnetic properties of individual lanthanide ions. The Ln(III) complexes (Ln = Dy, Tb) display field-induced slow magnetization relaxation, typical of single-molecule magnet behavior. The four lanthanide ions in the molecules are well separated by distances of ca.

[FTIR spectral fitting algorithm based on continuous wavelet transform].

An FTIR spectrum fitting algorithm based on continuous wavelet transform is proposed. In calculating the factor of difference spectrum, the algorithm takes into account both the original spectrum and its continuous wavelet transformed spectra, which effectively overcomes the problem of reference peak selection and manual factor selection in most commercial software. The detailed discussions on wavelet scale, order and basis are included.

[Feasibility of complete mesocolic excision in elderly patients with colon cancer].

Objective: To explore the short-term outcomes and safety of complete mesocolic excision (CME) in elderly patients with colon cancer.

Methods: The clinical pathological factors of 71 patients with colon cancer undergoing CME procedure by the same group of surgeons were analyzed retrospectively from November 2009 to February 2012. The elderly group(≥70 years) and the non-elderly group(<70 years) were compared regarding short-term outcomes and safety.

Syntheses, structure, and magnetic properties of hexanuclear Mn(III)(2)M(III)(4) (M = Y, Gd, Tb, Dy) complexes.

The synthesis and characterizations of a family of isomorphous [Mn(III)(2)M(III)(4)L(2)(μ(4)-O)(2)(N(3))(2)(CH(3)O)(2)(CH(3)OH)(4)(NO(3))(2)]·2H(2)O (M = Y(1), Gd(2), Tb(3), Dy(4)) are reported, where H(4)L = N,N'-dihydroxyethyl-N,N'-(2-hydroxy-4,5-dimethylbenzyl)ethylenediamine. They were obtained from the reactions of H(4)L with M(NO(3))(3)·6H(2)O, Mn(ClO(4))(2)·6H(2)O, NaN(3) and NEt(3) in a 1:1:1:2:2 molar ratio. The core structure consists of a Mn(2)M(4) unit.
