Thymoquinone is a chief phytochemical constituent of black cumin seed oil (BCSO) and shows strong bioactivity. It has a weak stability against environmental conditions like heat and light. Encapsulation process by Saccharomyces cerevisiae is a popular technique to preserve the bioactivity and increase the stability of functional bioactive compounds. In the current study, BCSO was encapsulated by both plasmolysed (PYC) and nonplasmolysed yeast cell (NPYC) and stability of thymoquinone and bioactive properties of all samples were evaluated. And also, some physicochemical, morphological and conformational characterizations were carried out for the encapsules. The results showed that thymoquinone concentration and its bioactivity were preserved better in PYC during storage compared to BCSO and NPYC. The highest degradation ratio of thymoquinone during storage for the BCSO was 96.78% while the lowest one was for the PYC sample (52.63%).

A Pilot Trial of the Immunogenicity, and Safety of GI-4000; an Inactivated Recombinant Saccharomyces Cerevisiae Expressing Mutant Ras Protein, as Consolidation Therapy Following Curative Treatment for Stage I-III Non-Small Cell Lung Cancer (NSCLC) With Tu
This is a consolidation therapy trial evaluating GI-4000 in subjects with NSCLC treated with curative intent who are disease free at their first post-treatment restaging assessment.
A member of the Rho family of MONOMERIC GTP-BINDING PROTEINS from SACCHAROMYCES CEREVISIAE. It is involved in morphological events related to the cell cycle. This enzyme was formerly listed as EC 188.8.131.52.
Proteins obtained from the species SACCHAROMYCES CEREVISIAE. The function of specific proteins from this organism are the subject of intense scientific interest and have been used to derive basic understanding of the functioning similar proteins in higher eukaryotes.
A species of the genus SACCHAROMYCES, family Saccharomycetaceae, order Saccharomycetales, known as "baker's" or "brewer's" yeast. The dried form is used as a dietary supplement.
A set of nuclear proteins in SACCHAROMYCES CEREVISIAE that are required for the transcriptional repression of the silent mating type loci. They mediate the formation of silenced CHROMATIN and repress both transcription and recombination at other loci as well. They are comprised of 4 non-homologous, interacting proteins, Sir1p, Sir2p, Sir3p, and Sir4p. Sir2p, an NAD-dependent HISTONE DEACETYLASE, is the founding member of the family of SIRTUINS.
A protein kinase encoded by the Saccharomyces cerevisiae CDC28 gene and required for progression from the G1 PHASE to the S PHASE in the CELL CYCLE.
