The eyestalk ablation of mud crabs hastened the ripening of ovaries without decreasing the survival rate.

These hybrids when employed in bioactive scaffolds can exhibit potential applications in tissue engineering and bone regeneration. Immunology and Infection Reverse Transcription Loop-Mediated Isothermal Amplification (RT-LAMP) Assay for the Specific and Rapid Detection of Tilapia Lake Virus Theerawut Phusantisampan1, Pattarasuda Rawiwan2,3, Sri Rajiv Kumar Roy2, Malinee Sriariyanun4, Win Surachetpong2,3 1 We present an RT-LAMP assay for the detection of TiLV in tilapia fish using simple instruments over a relatively short period of time compared to conventional RT-PCR techniques. This protocol may help control the epidemic spread of TiLVD, especially in developing countries. Environment Detection of Tilapia Lake Virus Using Conventional RT-PCR and SYBR Green RT-qPCR Pamela Nicholson1, Pattarasuda Rawiwan2, Win Surachetpong2 1Institute of Veterinary Bacteriology Vetsuisse Faculty, University of Bern, 2Department of Veterinary Microbiology and Immunology and Center for Advanced Studies for Agriculture and Food, Kasetsart University Institute for Advanced Studies, Kasetsart University This protocol diagnoses Tilapia Lake Virus (TiLV) in tilapia tissues using RT-PCR methodologies. The entire method is described from tissue dissection to total RNA extraction, followed by cDNA synthesis and detection of TiLV by either conventional PCR or quantitative PCR using dsDNA binding a fluorescent binding dye.
