Effects of high-pressure processing on the functional properties of pork batters containing Artemisia sphaerocephala krasch gum.

Here, the effect of high-pressure conditions (0.1-400 MPa) on the water-loss, texture, gel strength, color, dynamic rheological property, and water migration of pork batters containing 0.1% (W/W) Artemisia sphaerocephala krasch gum (PB-AG) is studied.

The effects of sodium chloride on proteins aggregation, conformation and gel properties of pork myofibrillar protein Running Head: Relationship aggregation, conformation and gel properties.

The objective of this study was to evaluate relationship with aggregation, secondary structures and gel properties of pork myofibrillar protein with different sodium chloride (1%, 2% and 3%). When the sodium chloride increased from 1 to 3%, the active sulfhydryl, surface hydrophobicity, hardness and cooking yield of myofibrillar protein were increased significantly ( < 0.05), the particle size, total sulfhydryl and Zeta potential were decreased significantly ( < 0.

[Establishment of hematological malignancy model in ex vivo cell culture].

The aim of this study was to develop an ex vivo cell culture system for establishing the hematological malignancy model. Mouse bone marrow cells were transfected with GFP-expressed retroviral vectors encoding various leukemia/lymphoma-associated fusion proteins (TEL-PDGFR, Rabaptin5-PDGFR, p210BCR-ABL, AML1-ETO, NPM-ALK). After transfection, the cells were cultured in IMDM containing 10% FCS without growth factors, or with one of the following growth factor combinations: (1) murine c-kit ligand (KL) plus human flt3 ligand (FL); (2) IL-3, thrombopoietin, G-CSF, and hyper-IL-6 (3/T/G/H6); (3) KL/FL plus 3/T/G/H6.

[Long-term expansion of T cell progenitors by JAK3 gene transduced primitive hematopoietic cells in vitro].

Objective: To explore whether activation of the JAK3-signaling pathway can stimulate long-term expansion of the earliest T cell progenitors from transduced primitive hematopoietic cells and evaluate their potential ability of committed differentiation.

Methods: A retrovirus vector (RV) containing JAK3 gene, two binding sites for chemical inducers of dimerization (AP20187), and green fluorescence protein (GFP), MGI-F(2)JAK3, was constructed. The RV vector MGI-F(2)JAK3 was then transduced into murine bone marrow hematopoietic cells.

[Promotion of in vitro long term expansion of primitive multipotential hematopoietic cells by transduced JAK2 gene].

Objective: To explore whether activation of the JAK2-signaling pathway can stimulate long-term expansion and regulation of hematopoietic stem cells/multipotential hematopoietic progenitor cells (HSC/MHPC), and evaluate their potential ability of committed differentiation.

Methods: A retrovirus vector (RV) which contains JAK2 gene and two binding sites for a chemical inducers of dimerization (AP20187) was constructed. JAK2 can be dimerized by adding AP20187.

[Long term regulated expansion and committed differentiation of JAK2 gene transfected hematopoietic stem/progenitor cells in vitro].

Objective: To explore the feasibility of regulated expansion and committed differentiation potential of JAK2 gene modified hematopoietic stem/progenitor cells in vitro.

Methods: A murine stem cell virus (MSCV) based retroviral vector MGI-F2Jak2, which encodes a green fluorescent protein (GFP) and a fusion protein containing two copies of modified FK506 binding protein (F36v) linked tyrosine kinase JAK2 was cloned. F36v served as a high-affinity binding site for dimerizer AP20187.
