Objective: To evaluate the efficacy and safety of intracytoplasmic morphologically selected sperm injection (IMSI) versus intracytoplasmic sperm injection (ICSI) in in vitro fertilization (IVF) for couples with male factor infertility.

Methods: Using the Cochrane system evaluation method, we searched MEDLINE, EMBASE, CENTRAL, ClinicalTrials.gov, and SinoMed and manually searched the reference lists of the included studies and relevant reviews for randomized controlled trials (RCT) comparing ICSI and IMSI published from 1992 to July 2017.

This systematic review aimed to evaluate the efficacy and safety of assisted hatching (AH) performed in couples with advanced maternal age. We searched for randomized controlled trials (RCTs) in electronic databases, including MEDLINE, EMBASE and CENTRAL (from inception to January 2018); in addition, we hand-searched the reference lists of included studies and similar reviews. We included RCTs comparing AH versus no treatment (control).

Hepatitis B virus (HBV) is the most common of the hepatitis viruses that cause chronic liver infections in humans and it is considered a major global health problem. However, the mechanisms of HBV replication are complex and not yet fully understood. In this study, the HBV DNA-transfected HepG2.

Quantitative proteomics can be used as a screening tool for identification of differentially expressed proteins as potential biomarkers for cancers. Here, we comparatively analyzed the proteome profiles of ovarian cancer tissues and normal ovarian epithelial tissues. Using the high-throughput proteomic technology of isobaric tags for relative and absolute quantitation (iTRAQ)-coupled with two-dimensional-liquid chromatography-tandem mass spectrometry, 1,259 unique proteins were identified.

Multi-drug resistance (MDR) is a major obstacle towards a successful treatment of hepatocellular carcinoma (HCC). The mechanisms of MDR are intricate and have not been fully understood. Therefore, we employed a cell-line model consisting of the 5-fluorouracil (5-FU) resistant BEL7402/5-FU cell line and its parental BEL7402 cell line.

Ski is an avian sarcoma virus oncogene homolog best known for inhibiting TGF beta signaling through its association with the SMAD proteins. Anti-Ski antibodies (MAbs) of high titer were prepared by immunizing BALB/c mice with multifocal intradermal injections and fusing high titer antibody producing spleen cells with myeloma cells of SP2/0 origin. Three MAbs were selected for further characterization as classes and subclasses.

Multidrug resistance (MDR) is a major obstacle towards a successful treatment of gastric cancer. However, the mechanisms of MDR are intricate and have not been fully understood. To elucidate the molecular mechanisms of MDR in gastric cancer, we employed the proteomic approach of isobaric tags for relative and absolute quantification (iTRAQ), followed by LC-MS/MS, using the vincristine-resistant SGC7901/VCR cell line and its parental SGC7901 cell line as a model.

In order to understand the molecular mechanisms of multidrug resistance (MDR) in ovarian cancer, we employed the proteomic approach of isobaric tags for relative and absolute quantification (iTRAQ), followed by LC-MS/MS, using the cisplatin-resistant COC1/DDP cell line and its parental COC1 cell line as a model. A total number of 28 proteins differentially expressed were identified, and then the differential expression levels of partially identified proteins were confirmed by Western blot analysis and/or real-time RT-PCR. Furthermore, the association of PKM2 and HSPD1, two differentially expressed proteins, with MDR were analyzed, and the results showed that they could contribute considerably to the cisplatin resistance in ovarian cancer cell.
