Diffuse large B-cell lymphoma (DLBCL) is a genetically heterogeneous non-Hodgkin lymphoma that is extremely aggressive and has an intermediate to high malignancy. Some patients still experience treatment failure, relapse, or resistance to rituximab, cyclophosphamide, adriamycin, vincristine, and prednisone (R-CHOP) therapy. Therefore, there is an urgent need for further research on new agents for the treatment of DLBCL.

Background: Circulating tumor cells (CTCs) and survivin are indicators for tumor stage and metastasis, as well as epitheliomesenchymal transition, in various cancers, including hepatocellular cancer (HCC).

Aim: To explore the potential of survivin-positive CTCs, specifically, as a marker for tumor progression in HCC patients.

Methods: We examined the survivin expression pattern in CTCs obtained from 179 HCC patients, and investigated the effects of survivin silencing and overexpression on the proliferation and invasion of HCC cells.

3,4-Dihydroxyphenylethanol (DOPET) is a potent antioxidant polyphenolic compound. In this study, our objective was to investigate the underlying mechanism of the neuroprotective role of DOPET in attenuating spinal cord injury (SCI). Initially, SCI was induced by performing surgical laminectomy on the rats at T10-T12 level.

In this study, a imaging system with hyperspectral reflectance, transmittance and interactance was constructed for estimate the firmness and elastic modulus of blueberry. The comparisons of these three imaging modes were carried out. This hyperspectral system could also be applied for scattering modewhile this mode was not suitable for small fruit such as blueberry.

In practice, food products tend to be contaminated with food-borne pathogens at a low inoculum level. However, the huge potential risk cannot be ignored because microbes may initiate high-speed growth suitable conditions during the food chain, such as transportation or storage. Thus, it is important to perform predictive modeling of microbial single cells.

The objectives of this study were to develop a probability model of Staphylococcus aureus enterotoxin A (SEA) production as affected by water activity (a(w)), pH, and temperature in broth and assess its applicability for milk. The probability of SEA production was assessed in tryptic soy broth using 24 combinations of a(w) (0.86 to 0.

Background: Hyperspectral reflectance and transmittance sensing as well as near-infrared (NIR) spectroscopy were investigated as non-destructive tools for estimating blueberry firmness, elastic modulus and soluble solid content (SSC). Least squares-support vector machine models were established from these three spectra based on samples from three cultivars viz. Bluecrop, Duke and M2 and two harvest years viz.

Homocysteine (Hcy) is regarded as a risk factor for hypertension, but research on the causal relationship between Hcy and hypertension is limited. In the present study, we prospectively tracked the blood pressure progression of a normotensive population with different Hcy levels over a 2-year period. The incidence of hypertension with increasing Hcy quartiles produced an approximately U-shaped curve, with significance in males.

Aim: To investigate the short-term efficacy and tolerability of radiotherapy plus thalidomide in patients with esophageal cancer (EC).

Methods: Serum samples from 86 EC patients were collected before, during, and after radiotherapy, and the vascular endothelial growth factor (VEGF) level was examined by ELISA. According to the change in serum VEGF level during radiotherapy, the patients were divided into two groups: in the drug group, VEGF level was increased or remained unchanged, and thalidomide was administered up to the end of radiotherapy; in the non-drug group, VEGF level was decreased and radiotherapy was given alone.

Retinitis pigmentosa (RP) is characterized by degeneration of the retinal photoreceptors and is the leading cause of inherited blindness worldwide. Although few genes are known to cause autosomal recessive RP (arRP), a large proportion of disease-causing genes remain to be revealed. Here we report the identification of SLC7A14, a potential cationic transporter, as a novel gene linked to arRP.

The aim of this paper is to give several characterizations for the property of weak exponential expansiveness for evolution families in Banach spaces. Variants for weak exponential expansiveness of some well-known results in stability theory (Datko (1973), Rolewicz (1986), Ichikawa (1984), and Megan et al. (2003)) are obtained.

The aim of this study was to investigate the expression patterns of IGF2 and IMP3 in osteosarcoma as well as its relationship with angiogenesis in the tumor. IGF2 and IMP3 expression was detected by immunohistochemical staining in the serial sections of the osteosarcoma. The impacts of IGF2 and IMP3 expression patterns on tumor angiogenesis were evaluated by statistics.

New expeditious total syntheses of (S)-camptothecin (16% overall yield, 95% ee) and (S)-10-hydroxycamptothecin (14% overall yield, 99% ee) have been accomplished, respectively, starting from readily available and inexpensive materials. Development, optimization, and successful application of the cascade reaction consisting of a pyrrolidine-catalyzed Michael addition, an intramolecular aldol condensation, and an oxidative aromatization, the intramolecular oxa Diels-Alder cycloaddition, and the Sharpless asymmetric dihydroxylation make these two new syntheses more efficient and straightforward.

In the title compound, catena-poly[[aquazinc(II)]-micro(3)-tyrosinato], [Zn(C(9)H(7)NO(3))(H(2)O)](n), each Zn atom has a distorted square-pyramidal geometry comprised of three O atoms and one N atom from three tyrosinate (tyr) ligands, and one aqua ligand. Two inversion-related Zn(2+) ions are bridged by two O atoms from the phenolate groups of two tyr ligands to form a centrosymmetric dimeric unit, which can be described as a planar Zn(2)O(2) four-membered ring. These repeating dimeric units are arranged along the c axis to give a one-dimensional chain coordination polymer, in which the tyr ligand adopts an unusual chelating/bridging coordination mode.
