Literature ReviewOpen accessEvery word in the titleControl of Contamination of Tissue Plant Cultures During in Vitro Clonal MicropropagationIrina Anikina, Nursultan Kaynidenov, Dora Dayu Rahma Turista et al.Plant micropropagation is currently an important method for modern large-scale propagation of valuable plant crops. Among the risks limiting the success of this method is the contamination of cultured plants. Conventional surface sterilization methods are not always effective against internal infection of plant tissues, and secondary contamination of tissue cultures during replication is also a major problem. This causes scientific … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 8 Apr 2025 · 8,693 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIn silico and in vitro Structural Analysis on the Interaction of Calmodulin and Calmodulin-Binding Motif of FKBP35 from Plasmodium knowlesiSazlinawatie Aladin, Cahyo Budiman et al.FK506-binding protein 35 (FKBP35) is a peptidyl-prolyl cis-trans isomerase found in Plasmodium knowlesi, a zoonotic malaria parasite responsible for concerning cases of malaria infection in East Malaysia. This protein contains a segment known as the calmodulin-binding motif (Pk-CBM), which is predicted to facilitate interaction with calmodulin from P. knowlesi (Pk-CaM). Although this interaction is considered promising for future antimalarial drug … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 10 Mar 2025 · 4,846 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIn vitro Kinematics Semen Tolerance to Oxidative StressCyril Mpho PilaneInterpretation of semen kinematic parameters remain as a point of discussion in predicting semen quality following processes like cryopreservation. During cryopreservation, oxidative stress remains a challenge in promoting post-thaw semen quality. Comparison of livestock semen exposed to oxidative stress, in vitro, highlight various aspects of sperm cell movement, like kinematics, to predict their qualities. Sperm cell kinematics includes the measurement … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 13 Sep 2024 · 4,560 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAugmentation of Temperatures, Media and Cryoprotectants on in vitro Fertilization of Pig OocytesTumelo Thelma Maduwa, Masindi Lottus Mphaphathi et al.There are numerous challenges to the large-scale production of pig embryos using in vitro procedures. The aim of the present study was to compare the different holding temperatures, in vitro maturation media, and permeating cryoprotectants in the in vitro fertilization of pig oocytes. Ovaries were obtained from the local slaughterhouse, oocytes were retrieved by means of aspiration and slicing techniques … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 29 Aug 2024 · 4,650 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTestosterone Concentration, Libido and Spermatozoa Quality in Gembrong Goats after in vivo and in vitro PGF2α AdministrationHusnurrizal, Sri Wahyuni et al.The Gembrong goat population is currently in a critical state. The preliminary study results show that one of the factors causing the population decline is the low fertility of male goats characterized by low sperm quality. The improvement of the spermatozoa quality can be performed with the administration of PGF2α. This study aims to determine the difference in semen quality … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 2 · 29 Apr 2024 · 5,541 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimization of Preparation Procedures of Phlorizin-Zn (Ⅱ) Complex and Its Antioxidant Activity Study in vitroYuqing Zhang, Yaping Li, Guorui Yang et al.Flavonoid metal complexes possess more effective antioxidant properties than flavonoids. However, the preparation of the phlorizin-Zn (Ⅱ) complex and its antioxidant activity has not been reported. In this research, the preparation procedures of the phlorizin-Zn (Ⅱ) complex were enhanced using by single factor test and Response Surface Methodology (RSM). The optimal preparation procedures of the phlorizin-Zn (II) complex were as … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 4 · 3 Apr 2024 · 4,758 accessesView PDFCite

In experiment 1: The oocytes were incubated at various temperatures of 35.5, 36.5, 37.5, 38.5, 39.5 and 40.5°C under similar conditions with 5% CO2, in humidified air for 22 h. … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 4 · 16 Nov 2023 · 5,319 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIn vitro Ruminal Cumulative Gas and Methane Production, Enzyme Activity, Fermentation Profile and Nutrient Digestibility on Feed Supplemented with Organic SeleniumMoh. Sofi’ul Anam, Andriyani Astuti, Budi Prasetyo Widyobroto et al.Methane (CH4) emissions are indeed a global environmental concern and ruminants are a significant source of these emissions; however, there is limited understanding regarding the contribution of organic Selenium (Se) in mitigating CH4 emissions. Hence, this study investigated the impact of supplementing organic Se from Selenomethionine (Se-Met) on the in vitro ruminal cumulative gas and CH4 production, fermentation profile, enzyme … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 4 · 26 Oct 2023 · 5,215 accessesView PDFCite
