Clinical value of Cyclin D1 and P21 in the differential diagnosis of papillary thyroid carcinoma.

Background: With the continuous discovery of new borderline thyroid lesions and benign and malignant "gray areas", coupled with the limitations of traditional immune indicators, the differential diagnosis of papillary thyroid carcinoma (PTC) has become more difficult. Cyclin D1 and P21 are cell cycle regulators involved in the occurrence and metastasis of multiple tumors, including PTC, but their specific functions are unclear.

Methods: In our study, immunohistochemical staining was used to explore the expression of Cyclin D1 and P21 in PTC, paracancerous tissue, follicular adenoma (FA) and papillary thyroid hyperplasia.

Fusion of apoptosis-related protein Cytochrome c with anti-HER-2 single-chain antibody targets the suppression of HER-2+ breast cancer.

Cancer treatment has gradually developed from toxic chemotherapy to targeted therapy with fewer side effects. Approximately 30% of breast cancer patients overexpress human epidermal growth factor receptor 2 (HER-2). Previous studies have successfully produced single-chain antibodies (scFv) targeting HER-2+ breast cancer; however, scFv have poor stability, easy aggregation and a shorter half-life, which have no significant effect on targeting therapy.

-Terphenyls and actinomycins from a sp. associated with the larva of mud dauber wasp.

In the course of searching for cytotoxic metabolites from insects associated actinomyces, two new natural -terphenyl glycosides, strepantibin D () and strepantibin E (), along with terferol (), actinomycin D (), actinomycin V () and actinomycin V (), were identified from the fermentation medium of a sp. which was obtained from the larva body of mud dauber wasp. Strepantibin D (), previously reported as a synthetic derivative of terfestatin A, is firstly isolated as a natural -terphenyl in this research.

Delivery System Targeting Hemagglutinin of Influenza Virus A to Facilitate Antisense-Based Anti-H1N1 Therapy.

Antisense oligonucleotides (ODNs) are therapeutic molecules that hybridize to complementary target mRNA sequences. To further overcome the poor cellular uptake of ODNs, we proposed a novel strategy to deliver ODNs by conjugating the anti-influenza A virus (IAV) ODN with a peptide showing high affinity to the hemagglutinin (HA) on the surface of IAV particles or the IAV-infected host cells. The HA-specific binding peptides were selected by phage display, and the individual binding clones are characterized by DNA sequencing, and the selected phage was further assayed by enzyme-linked immunosorbent assay.

Activating AKT to inhibit JNK by troxerutin antagonizes radiation-induced PTEN activation.

Radiotherapy is one of the most effective non-surgical treatments for many tumors. However, radiation damage remains a major negative consequence of radiotherapy.

[Synthesis and antisense properties of 2’β-F- and 2’α-F-2’-deoxy-uridines modified oligonucleotides with 4’-C-(2-methoxyethoxy) substituent].

Background: To study the radioprotective effects of flavonoids from Rosa roxburghii Tratt (FRT).

Materials And Methods: The radioprotective effects of FRT were investigated by examining cell viability, 30-day survival of mice and the number of colony-forming units in spleen (CFU-S) after total-body 60Co irradiation.

Results: The survival rates of irradiated cells gradually increased with increasing concentrations of FRT.

Amentoflavone acts as a radioprotector for irradiated v79 cells by regulating reactive oxygen species (ROS), cell cycle and mitochondrial mass.

Radioprotective effects of amentoflavone were investigated by examining cell viability, apoptosis, cell cycling concentrations of intracellular ROS (reactive oxygen species), and relative mitochondrial mass by flow cytometry after 60Co irradiation. Pretreatment with amentoflavone 24 hours prior to 8 Gy 60Co γ-ray irradiation significantly inhibited apoptosis, promoted the G2 phase, decreased the concentration of ROS and mitochondrial mass. These results collectively indicate that amentoflavone is an effective radioprotective agent.

[The experiment research on solution refractive index sensor based on tilted fiber Bragg grating].

The present paper analyzes the sensor's basic principle of the bare tilted fiber Bragg grating (TFBG) and surface plasmon resonance sensor (SPR) that deposited nanoscale gold-coating on the surface of the cladding. We simulated the transmission spectrums and some order cladding mode of TFBG in different concentration solutions by Integration and optical fiber grating software OptiGrating. So by the graphic observation and data analysis, a preliminary conclusion was got that in a certain sensing scope, the cladding modes of TFBG shift slightly to right with the increasing the solution refractive index(SRI),and the relation between resonance peak caused by the coupling of core mode and a certain cladding mode and the SRI was linear.

The analysis of major impurities of lipophilic-conjugated phosphorothioate oligonucleotides by ion-pair reversed-phase HPLC combined with MALDI-TOF-MS.

A simple and rapid ion-pair reversed phase high-performance liquid chromatography (IP-RP-HPLC) method was developed to analyse the major impurities of lipophilic-conjugated phosphorothioate oligonucleotides (ODNs), which provided better separation performance than capillary gel electrophoresis and ion exchange chromatograph methods. The study showed that covalent conjugations of lipophilic group (docosanyl, C(22)) to ODN at 5'-termini (denoted as 5'C(22)-Flu) or 3'-termini (denoted as 3'C(22)-Flu) exhibited similar chromatographic retention behavior. Some important analytical conditions of IP-RP-HPLC, including column type, ion-pairing buffer composition, and separation temperature, were investigated for the effects on the separation of crude 5'C(22)-Flu.

CD45-associated protein promotes the response of primary CD4 T cells to low-potency T-cell receptor (TCR) stimulation and facilitates CD45 association with CD3/TCR and lck.

Although it is clear that the CD45 tyrosine phosphatase is required for efficient T-cell activation and T-cell development, the factors that regulate CD45 function remain uncertain. Previous data have indicated that there is an association of CD45 with CD4 and the T-cell receptor (TCR) complex controlled by the variable ectodomain of CD45 and, following activation, by high- and low-potency peptides. This suggests that controlling substrate access to CD45 may be an important regulatory mechanism during T-cell activation.

Sequence confirmation of synthetic phosphorothioate oligodeoxynucleotides using Sanger sequencing reactions in combination with mass spectrometry.

A protocol relying on Sanger sequencing reactions in combination with mass spectrometry (MS) for sequence confirmation of antisense phosphorothioate oligodeoxynucleotides is described. In this procedure, synthetic phosphorothioate oligodeoxynucleotides are used as reverse primers for extension of matched templates with enough length (approximately 150-300 bp) for well-established Sanger sequencing. Because the complementary strand of modified primer is used directly for sequencing primer extension, the base order shown in the sequencing result is reversely complementary to phosphorothioate oligodeoxynucleotide.
