  1. 1. Temperaturens inverkan på tillväxt av olika mikroorganismer på frysta livsmedel

    University essay from SLU/Department of Molecular Sciences

    Author : Almohannad Alahmad; [2022]
    Keywords : Frysning; ; förskämning; hållbarhet; mikroorganism; upptining;

    Abstract : Metoder för att bevara mat har varit en viktig aspekt för att säkra livsmedelsförsörjningen genom historien. Frysning och andra konserveringsmetoder har använts med framgång under årens lopp för att förlänga livsmedels hållbarhetstid, men det finns ibland mikroorganismer på livsmedel som kan växa till mängder som kan leda till sjukdom och utgöra problem för individers hälsa, eller så kan de förskämma livsmedel.

  3. 2. Formulation development of a recombinant VAR2-antiCD3 protein for cancer immunotherapy

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Maja Warlin; Frida Hallberg; [2021]
    Keywords : immunotherapy; cancer; pharmaceuticals; proteins; analytical techniques; molecular biotechnology; formulation; life science; engineering; pharmaceutical technology; Technology and Engineering;

    Abstract : The use of immunotherapy for treating cancer has received a lot of attention in the recent years. The therapy is based on activating or deactivating the patient’s own immune system to help fight the disease. One way of doing this, is using bispecific molecules that can target both cancer cells and T-cells simultaneously. READ MORE

  5. 4. The effect of the natural antioxidants catalase and epigallocatechin added after thawing on the quality of dromedary camel spermatozoa

    University essay from SLU/Dept. of Clinical Sciences

    Author : Johanna Grundin; [2018]
    Keywords : Camel semen; cryopreservation; antioxidants; reactive oxygen species; sperm quality analysis;

    Abstract : The objective of this study was to evaluate the effect of adding two natural antioxidants (Catalase and Epigallocatechin) to the thawing media on the quality of cryopreserved dromedary camel spermatozoa post-thaw. Also, an indirect measure of ROS production was performed by measuring malondialdehyde (MDA) production (a product of oxidative damage) post-thaw. READ MORE

  6. 5. Effect of freezing and thawing rates on camel sperm quality

    University essay from SLU/Dept. of Clinical Sciences

    Author : Bodil Elwing; [2017]
    Keywords : Camel semen; cryopreservation; freezing rate; thawing temperature; motility analysis;

    Abstract : The objective of this study was to evaluate the effect of different freezing rates and thawing temperatures on the quality of camel spermatozoa post thawing. Ten ejaculates from five male camels were frozen at five different freezing rates, achieved by placing the straws at specific heights above the surface of liquid nitrogen for different times (4 cm for 15 min; 1 cm for 15 min; 7 cm for 15 min; 7 cm for 5 min + 4 cm for 3 min; 4 cm for 5 min + 1 cm for 3 min) followed by storage in liquid nitrogen.
