Due to its storage and retrieval efficiency, cross-modal hashing (CMH) has been widely used for cross-modal similarity search in many multimedia applications. According to the training strategy, existing CMH methods can be mainly divided into two categories: relaxation-based continuous methods and discrete methods. In general, the training of relaxation-based continuous methods is faster than that of discrete methods, but the accuracy of relaxation-based continuous methods is not satisfactory.

- Hashing is effective for large-scale search because it offers low storage costs and quick query speeds, and supervised hashing can significantly improve performance over unsupervised methods.
- Discrete supervised hashing optimizes the binary coding process using supervised information, while deep hashing combines deep feature learning with hash-code learning in a unified system.
- The proposed method, deep discrete supervised hashing (DDSH), is the first to leverage pairwise supervised information to guide both discrete coding and feature learning simultaneously, resulting in superior image retrieval performance in experiments.
Focal adhesion kinase (FAK), which plays a pivotal role in mediating cell proliferation, survival and migration, is frequently overexpressed in human colon cancer. In the present study, we utilized the short hairpin RNA (shRNA) to knock down the expression of FAK in SW480 human colon cancer cells in vitro. Furthermore, nude mice bearing human colon carcinoma SW480 were established and treated with plasmids encoding FAK shRNA encapsulated in DOTAP: Chol cationic liposome through tail vein injection.

Methods: SEREX technique with some modifications was applied. In brief, immune sera from rabbit immunized with human chorionic tissue were used to screen human placenta tissue cDNA expression library.
Objective: To explore the effects of total flavonoids of Hippophae rhamnoides L. (TFH), quercetin (Que) and isorhamnetin (Isor) on the intracellular free calcium ([Ca(2+)](i)) in vascular smooth muscle cells (VSMC) of spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY).
Methods: Fluo 3-acetoxymethylester (Fluo-3/AM) was used to observe the effects of TFH (100 mg/L) and its essential monomers, namely Que (10(-4) mol/L) and Isor (10(-4) mol/L) on changes of [Ca(2+)](i) in cultured SHR and WKY VSMC (abbr.
