Research ArticleOpen accessIn the keywordsSynergistic Effect of Insulin on in vitro Development of Immature Bovine OocytesMojtaba Dashtizad, Abd Wahid Haron, Rosnina Yusoff et al.Problem statement: Development of efficient culture system to support embryonic development would be valuable when quality of produced embryos was important. However, the rate of bovine embryo production in vitro was still lower than expected. Present study, including of three experiments, was carried out to investigate the effect of insulin on nuclear maturation and subsequent development of immature bovine oocytes … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 31 Dec 2010 · 10,433 accessesView PDF Cite

Review ArticleOpen accessIn the abstractAdvances in Modern Biotechnological Tools for Sustainable Control of Plant Viral DiseasesNabela Akter, Ankita Saha, Md. Abdullah Al Sabbir, Md. Motaher HossainPlant viruses pose a major threat to global food production, causing yield losses across many staple and horticultural crops. Conventional breeding for resistance is typically slow and constrained by the number of available natural resistance genes. Recent breakthroughs in biotechnology have enabled the development of accurate, flexible, and environmentally friendly technologies to confer virus resistance. This review summarizes exciting developments … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 16 Jul 2026 · 726 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCloning and Expression of SCAMP3 in Transgenic Silkworm (Bombyx mori)Selly S. Rajagukguk, Sabar Pambudi, Astari Dwiranti et al.SCAMP3 (Secretory Carrier Membrane Protein 3) is a crucial component of vesicular trafficking pathways and plays important roles in endocytosis and protein recycling. Previous studies demonstrate SCAMP3 dysregulation in various cancers, suggesting potential applications as a biomarker and therapeutic target. Understanding SCAMP3 expression and post-translational processing provides insights into its biological functions and potential applications in cancer diagnostics and therapy. … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 16 Feb 2026 · 1,521 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Novel Industrially Promising Keratinase Isolated from Aspergillus aureolatus Changes its Substrate Specificity after pH-Mediated AutolysisArina Mokhova, Anna ShestakovaMicrobial proteolytic enzymes are green catalysts with many potential applications. Keratinolytic enzymes (or keratinases) are crucial for efficient keratin degradation, making them essential in waste management, biomedicine, cosmetics, and various industrial applications. This study describes the production and characterization of a protease with keratinolytic activity from Aspergillus aureolatus. The protease was isolated from the culture fluid on the 5th day … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 14 Feb 2025 · 5,580 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparison of in vitro Maturation Media on Cattle Oocytes after in vitro Embryo ProductionSindisiwe Mbali Sithole, Masindi Lottus Mphaphathi et al.The study was conducted to compare differences in vitro maturation media and their effect on subsequent in vitro embryo production. The study procedures were approved by the agricultural research council animal ethics committee (Ref no: APAEC 2020/05) and the Tshwane university of technology animal research ethics committee (Ref no: AREC 2021/08/004).

Mphaphathi, Edward C. Webb, Ayanda MaqhashuThe objectives of the study were to: Compare oocyte retrieval methods (aspiration and slicing) from pig ovaries on oocyte quality and quantity; compare in vitro maturation (IVM) media (North Carolina State University -NCSU 37; Tissue Culture Medium-TCM 199; and porcine follicular fluid-mpFF) on oocytes polar body extrusion; compare the effect of Electrical Stimulation (ES) and frozen-thawed semen on cleavage rates … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 5 Jan 2022 · 6,600 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy the Effect of Extracted Low-Density Lipoprotein from Egg Yolk on the Cryopreservation of Nguni Bull SemenMduduzi M. Tshabalala, Masindi Lottus Mphaphathi, Khathutshedzo A. Nephawe et al.The mechanism on how Egg Yolk (EY) helps sperm to survive the low temperature outside the animal body during cryopreservation and thawing process is not yet known. It is usually believed that the Low-Density Lipoprotein (LDL) is the major component that provides protection. The present study was undertaken to assess the cryo-protective effect of different concentrations (6, 8, 10 and … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 3 · 13 Sep 2021 · 6,915 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Endoribonuclease Domain of IRE1 and its Substrate HAC1 are Structurally Linked Components of the Unfolded Protein Response in FungiLuis David Maldonado-BonillaThe unfolded protein response sustains the folding capacity of the endoplasmic reticulum under conditions that increase the activity of the secretory pathway. In fungi, the unfolded protein response exclusively depends on the kinase/endoribonuclease IRE1, which senses the accumulation of unfolded proteins in the endoplasmic reticulum lumen and catalyzes the committed step in the unconventional splicing of HAC1 mRNA that encodes … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 14 Oct 2020 · 6,541 accessesView PDF Cite
