"ABSTRAK
Kriopreservasi merupakan metode penyimpanan materi genetik pada suhu yang rendah dalam jangka waktu yang lama. Manfaat kriopreservasi salah satunya untuk mengatasi masalah penurunan populasi. Ikan kancra merupakan salah satu spesies dari famili Cyprinidae yang populasinya semakin menurun sehigga diperlukan upaya pelestarian. Faktor yang mempengaruhi keberhasilan kriopreservasi salah satunya adalah krioprotektan. Krioprotektan alami digunakan karena memiliki toksisitas yang lebih rendah dibanding krioprotektan dari bahan kimia. Kuning telur merupakan krioprotektan alami yang dapat menjaga sel selama proses kriopreservasi. Tujuan dari penelitian yaitu mengevaluasi efek kuning telur ayam kampung sebagai krioprotektan alami terhadap motilitas, viabilitas, abnormalitas dan fertilisasi spermatozoa 48 jam pascakriopreservasi. Konsentrasi kuning telur ayam kampung yang digunakan yaitu: 0%, 5%, 10%, 15%, 20% dan 25%. Rasio yang digunakan untuk pengenceran sperma yaitu 1:10. Analisis data menggunakan uji ANAVA kemudian dilanjutkan dengan uji Tukey. Berdasarkan hasil uji ANAVA satu arah diketahui bahwa krioprotektan kuning telur ayam kampung yang dikombinasikan dengan metanol 10% memberikan pengaruh (P<0,05) terhadap motilitas, viabilitas, abnormalitas dan fertilitas spermatozoa pascakriopreservasi. Konsentrasi kuning telur 5% merupakan konsentrasi optimum yang dapat mempertahankan persentase motilitas, viabilitas dan fertilitas tertinggi masing-masing 84,06 ± 1,67%, 82,13 ± 1,75% dan  92,96 ± 1,94% serta nilai persentase abnormalitas terendah 25,25 ± 2,22%.

ABSTRACT
Cryopreservation is a method of storing genetic material at low temperatures for long periods of time. One of the benefits of cryopreservation is to overcome the problem of population decline. The kancra fish is one of the species of the Cyprinidae family whose population is declining so that conservation efforts are needed. One of the factors that influence the success of cryopreservation is cryoprotectant. Natural cryoprotectants are used because they have lower toxicity than cryoprotectants from chemicals. Egg yolk is a natural cryoprotectant that can maintain cells during the cryopreservation process. The purpose of this study is to evaluate the effect of egg yolk as natural cryoprotectants on motility, viability, abnormalities, and fertilization of 48-hour spermatozoa after cryopreservation. Concentrations of free-range chicken egg yolk used are: 0%, 5%, 10%, 15%, 20% and 25%. The ratio used for sperm dilution is 1:10. Data analysis using the ANAVA test and then followed by the Tukey test. Based on the results of the one-way ANAVA test, it was found that cryoprotectant of free-range chicken egg yolk combined with 10% methanol had an effect (P <0.05) on motility, viability, abnormality, and fertility of post-cryoprotected spermatozoa. Egg yolk concentration of 5% was the optimum concentration that can maintain the highest percentage of motility, viability and fertility, respectively 84.06 ± 1.67%, 82.13 ± 1.75% and 92.96 ± 1.94% and the percentage value the lowest abnormality was 25.25 ± 2.22%."

"The volumes present a multidisciplinary approach to modeling and simulation of flows in the cardiovascular and ventilatory systems, especially multiscale modeling and coupled simulations. The cardiovascular and respiratory systems are tightly coupled, as their primary function is to supply oxygen to and remove carbon dioxide from the body's cells. Because physiological conduits have deformable and reactive walls, macroscopic flow behavior and prediction must be coupled to nano- and microscopic events in a corrector scheme of regulated mechanisms. Therefore, investigation of flows of blood and air in physiological conduits requires an understanding of the biology, chemistry, and physics of these systems together with the mathematical tools to describe their functioning.
Volumes 1 and 2 are devoted to cell organization and fate, as well as activities that are autoregulated and/or controlled by the cell environment. Volume 1 examined cellular features that allow adaptation to environmental conditions. Volume 2 begins with a survey of the cell types of the nervous and endocrine systems involved in the regulation of the vasculature and respiratory tract and growth factors. It then describes major cell events in the circulatory and ventilatory systems, such as cell growth, proliferation, migration, and death. Circadian cycles that drive rhythmic gene transcription are also covered.

"This new volume fills the gap in the literature as it will guide urologists and pathologists in the proper utilization of a variety of laboratory methods that are currently available to determine the presence, persistence or progression of tumors of the lower urinary tract. The volume emphasizes cytology of the urinary tract which is preferred over other methods (i.e. biochemical, immunological and cytogenetic) for its accuracy, especially for the important high grade tumors. This volume will appeal to urologists as well as pathologists, cytopathologists and related professions. The illustrations, nearly all in color, stress the key points of the text and enhance basic understanding of urothelial and other tumors of the urinary tract.
