Management of type 1 gastric neuroendocrine tumors: an 11-year retrospective single-center study.

Background: Type 1 gastric neuroendocrine tumors (NETs) are relatively rare to the extent that some physicians have little experience in diagnosing and treating them. The purpose of this study was to increase the understanding of the disease by analyzing and summarizing the management and prognoses of patients with type 1 gastric NETs at our center.

Methods: The data of 229 patients (59.

Effects of feeding on different parts of on the intestinal microbiota of and (Coleoptera: Curculionidae).

and (Coleoptera: Curculionidae) are two monophagous weevil pests that feed on (Mill.) Swingle but differ in their diet niche. In the field, adults of prefer to feed on the trunk of , whereas adults of prefer to feed on the tender parts.

Intraoperative thromboelastography-guided transfusion in a patient with factor XI deficiency: A case report.

Background: Factor XI (FXI) deficiency, also known as hemophilia C, is a rare bleeding disorder of unpredictable severity that correlates poorly with FXI coagulation activity. This often poses great challenges in perioperative hemostatic management. Thromboelastography (TEG) is a method for testing blood coagulation using a viscoelastic hemostatic assay of whole blood to assess the overall coagulation status.

Reproductive Dormancy in Overwintering Adult Eucryptorrhynchus brandti (Coleoptera: Curculionidae).

Dormancy is important for overwintering insects to resist and adapt to adverse conditions. Dormancy generally contains quiescence and diapause. Eucryptorrhynchus brandti Harold (Coleoptera: Curculionidae), tree-of-heaven trunk weevil (TTW), is a destructive pest and highly host-specific to Ailanthus altissima in China.

A theta-scheme approximation of basic reproduction number for an age-structured epidemic system in a finite horizon.

This paper focuses on numerical approximation of the basic reproduction number R, which is the threshold defined by the spectral radius of the next-generation operator in epidemiology. Generally speaking, R cannot be explicitly calculated for most age-structured epidemic systems. In this paper, for a deterministic age-structured epidemic system and its stochastic version, we discretize a linear operator produced by the infective population with a theta scheme in a finite horizon, which transforms the abstract problem into the problem of solving the positive dominant eigenvalue of the next-generation matrix.

Comparison of McGrath Series 3 and Macintosh Laryngoscopes for Tracheal Intubation in Patients With Normal Airway by Inexperienced Anesthetists: A Randomized Study.

Difficult and failed intubations account for the major causes of morbidity and mortality in current anesthetic practice. Several devices including McGrath Series 3 videolaryngoscope are available which may facilitate tracheal intubation by improving view of the larynx compared with Macintosh blade laryngoscopy. But no studies demonstrate whether McGrath Series 3 performs better than Macintosh laryngoscope in normal airway intubations by inexperienced anesthetists so far.

Melatonin attenuates hypertension-induced renal injury partially through inhibiting oxidative stress in rats.

The aim of the present study was to investigate the protective effects of melatonin (MLT) on hypertension-induced renal injury and identify its mechanism of action. Twenty-four healthy male Wistar rats were divided into a sham control group (n=8), which was subjected to sham operation and received vehicle treatment (physiological saline intraperitoneally at 0.1 ml/100 g), a vehicle group (n=8), which was subjected to occlusion of the left renal artery and vehicle treatment, and the MLT group (n=8), which was subjected to occlusion of the left renal artery and treated with MLT (10 mg/kg/day).

The Application of Quality Identification in Honey by Photoacoustic Spectroscopy.

The photoacoustic spectrum of glucose, sucrose and honey solutions in the visible range are measured by using the single-light photoacoustic spectrometer, and are compared with the spectra from spedtrophotometry method. The spectral characteristics of the above solutions show that the spectral background intensity and spectral profile have some differences for different kinds of solutions. The spectra of the three kinds of solutions all have strong peak value at 485 and 655 nm, but the intensity ratios between the two peaks are different.

[Adsorption of Cd2+ on biochar from aqueous solution].

Biomass-based materials such as biochar have a good performance in heavy metal adsorption. The adsorption of Cd2+ on biochar converted from cotton straw was studied. Adsorption isotherm, kinetics and effect factors such as temperature, pH and ionic strength were investigated.

[Expression of Bcl-w protein in human small intestinal adenocarcinoma and effect of Bcl-w siRNA on apoptosis in intestinal adenocarcinoma HuTu-80 cells].

Objective: To investigate the expression of apoptosis-related protein Bcl-w in adenocarcinoma of the small intestine, and the apoptotic effect of Bcl-w siRNA on small intestinal adenocarcinoma cells HuTu-80.

Methods: Forty-two tissue samples were examined in our study, including 7 cases from human small intestinal adenocarcinoma, and 35 cases from normal small intestine served as control. The expression of Bcl-w was detected by immunohistochemistry (IHC).

Significance of decreased apoptosis, role of Bid expression and Bcl-Xl/Bid ratio in human jejunal stromal tumors.

Given that the studies on human small intestinal stromal tumors are very limited, our study was designed to determine the significance of apoptosis, the role of some apoptosis-related proteins, including Bax, Bad, Bid, Bcl-2, Bcl-Xl, and Bcl-W, in jejunal stromal tumors (JST). For this purpose, 52 samples were examined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling and immunohistochemistry, including 40 cases from normal jejunum and 12 cases from the JST. The results showed that a significantly decreased apoptosis was observed in JST compared with normal jejunum (median of apoptotic index, 0.

Preparation of gold nanoparticles modified with tetrathiafulvalene via direct sulfur bridge.

A new tetrathiafulvalene-modified gold colloid was prepared. The modification or coordination of 2-[4,5-ethylenedisulfanyl-1,3-dithiol-2-ylidene]-1,3-dithiole-4-thiolate to the surface of gold nanoparticles was characterized by UV-Vis and Raman spectra, and cyclic voltammograms. The most valuable point of the modified gold nanoparticles is their redox activities.

The first example of solvothermally synthesized thioantimonates(V) with ethylenediamine coordinated lanthanide(III): [Sm(en)4]SbS4 x 0.5en and [Sm(en)3(H2O)(micro-SbS4)]infinity.

Under mild solvothermal conditions two novel thioantimonates(V) [Sm(en)4]SbS4 x 0.5en (1) and [Sm(en)3(H2O)(micro-SbS4)]infinity (2) were synthesized; the structure of 1 contains discrete [Sm(en)4]3+ and [SbS4]3 ions, while 2 consists of neutral [Sm(en)3(H2O) (micro-SbS4)] one-dimensional chains.
