Book Description
The Juvenile Salmon Acoustic Telemetry System (JSATS) was developed for the U.S. Army Corp of Engineers Portland District (USACE) to address questions related to survival and performance measures of juvenile salmonids as they pass through the Federal Columbia River Power System (FCRPS). Researchers using JSATS acoustic transmitters (ATs) were tasked with standardizing the surgical implantation procedure to ensure that the stressors of handling and surgery on salmonids were consistent and less likely to cause effects of tagging in survival studies. Researchers questioned whether the exposure time in 'knockdown' anesthesia (or induction) to prepare fish for surgery could influence the survival of study fish (CBSPSC 2011). Currently, fish are held in knockdown anesthesia after they reach Stage 4 anesthesia until the completion of the surgical implantation of a transmitter, varies from 5 to 15 minutes for studies conducted in the Columbia Basin. The Columbia Basin Surgical Protocol Steering Committee (CBSPSC) expressed concern that its currently recommended 10-minute maximum time limit during which fish are held in anesthetic - tricaine methanesulfonate (MS-222, 80 mg L-1 water) - could increase behavioral and physiological costs, and/or decrease survival of outmigrating juvenile salmonids. In addition, the variability in the time fish are held at Stage 4 could affect the data intended for direct comparison of fish within or among survival studies. Under the current recommended protocol, if fish exceed the 10-minute time limit, they are to be released without surgical implantation, thereby increasing the number of fish handled and endangered species 'take' at the bypass systems for FCRPS survival studies.

Book Description
The objective of this study was to determine the best overall suture material to close incisions from the surgical implantation of Juvenile Salmon Acoustic Telemetry System (JSATS) acoustic microtransmitters in subyearling Chinook salmon Oncorhynchus tshawytscha. The effects of seven suture materials, four surgeons, and two water temperatures on suture retention, incision openness, tag retention, tissue inflammation, and tissue ulceration were quantified. The laboratory study, conducted by researchers at the Pacific Northwest National Laboratory, supports a larger effort under way for the U.S. Army Corps of Engineers, Portland District, aimed at determining the suitability of acoustic telemetry for estimating short- and longer-term (30-60 days) juvenile-salmonid survival at Columbia and Snake River dams and through the lower Columbia River.

Book Description
Chemical anesthetics requiring a mandatory withdrawal period to allow for dissipation of drug residues pose severe limitations to acoustic research conducted at sea where captured fish undergo surgical implantation of transmitters and are released shortly after treatment. The efficacy and safety of three unrestricted approaches to anesthesia were evaluated in Gopher Rockfish Sebastes carnatus: carbon dioxide (CO2), sodium bicarbonate (NaHCO3), and pulsed direct current (pDC) electroanesthesia. These immediate-release methods were used to assess anesthetic induction and recovery times, plasma cortisol concentrations, and survival rates following surgery compared to those obtained from the widely used chemical anesthetic, tricaine methanesulfonate (MS-222). All anesthetics were effective at the concentrations tested. However, the times required to achieve stage IV anesthesia differed significantly, being shortest for electroanesthesia (nearly instantaneous) and longest for CO2 (3.56 ± 0.21 min [mean ± SE]). Recovery times were significantly longer for NaHCO3 (7.21 ± 1.17 min) and CO2 (7.78 ± 0.93 min) compared to pulsed DC electroanesthesia (3.76 ± 0.21 min) and MS-222 (3.65 ± 0.38 min). Plasma cortisol levels differed among treatments but tended to peak around 0.5 h post-anesthesia and decline within 2 h. Given the prolonged recovery times of NaHCO3 and CO2, electroanesthesia is the most preferable method for rapid induction, recovery, and immediate release of Gopher Rockfish following surgery at sea.

Book Description
Experimental surgery is an important link for the development in clinical surgery, research and teaching. Experimental surgery was part of the most important surgical discoveries in the past century. Since 1901 nine Nobel Prizes have been awarded to the pioneers had remarkable achievements in the basic or practical surgery. In recent 20 years, experimental surgery has achieved new advances, like laparoscopic and robotic surgery, tissue engineering, and gene therapy which are widely applied in clinic surgery. The present book covers wide experimental surgery in preclinical research models subdivided in two volumes. Volume I introduces surgical basic notions, techniques, and different surgical models involved in basic experimental surgery and review the biomechanical models, ischemia/reperfusion injury models, repair and regeneration models, and organ and tissue transplantation models, respectively. Volume II introduces several specific experimental models such as laparoscopic and bariatric experimental surgical models. The second volume also introduces graft-versus-host disease, and other experimental models. Review the advances and development of recent techniques such as tissue engineering, organ preservation, wound healing and scarring, gene therapy and robotic surgery. The book documents the enormous volume of knowledge we have acquired in the field of experimental surgery. In this book, we have invited experts from the United States, Canada, France, Germany, China, Japan, Korea, UK, Sweden, Netherland, Hungary and Turkey to contribute 36 chapters in the fields of their expertise. These two volumes are the compilation of basic experimental surgery and updated advances of new development in this field that will be invaluable to surgeons, residents, graduate students, surgical researchers, physicians, immunologists, veterinarians and nurses in surgery.

Book Description
Bringing together a distinguished interdisciplinary team of contributors, this volume provides a comprehensive exploration of translational toxicology—a systematic approach to developing therapeutic interventions that can protect against, mitigate, or reverse the effects of exposures. In particular, the book addresses modes of action and biomarkers, developmental risks of exposures, and potential translational toxicology therapeutics. The result is a compelling application of developmental toxicology in a new therapeutic discipline that is destined to become part of standard medical practice. Translational Toxicology: Defining a New Therapeutic Discipline is an essential text for regulatory authorities, scientists, and physicians who are concerned with environmental exposures, public health, nutrition, and pharmaceutical research and development. Basic science, epidemiological, and clinical investigators will also find this book a significant resource.
