Closed form solutions are obtained for a Fokker-Planck model for cell growth as a function of maturation velocity and degree of maturation. For reproduction rules where daughter cells inherit their parent's maturation velocity the complete solution is derived in terms of Airy functions. For more complicated reproduction rules partial results are obtained. Emphasis is given to the relationship o...

Many of the existing models on stage structured populations are single species models or models which assume a constant resource supply. In reality, growth is a combined result of birth and death processes, both of which are closely linked to the resource supply which is dynamic in nature. From this basic standpoint, we formulate a general and robust predator-prey model with stage structure wit...

Background: Dendritic cells (DCs) are professional antigen presenting cells that have an important role in the initiation of immune response. The use of maturation factors in dendritic cell differentiation provides a promising approach in immunotherapy. Objective: In this study, we compared tumor necrosis factor-α, polyribocytidylic acid, lipopolysacharide and CpG oligonucleotides in inducing d...

Background: This study examined the effect of including one of two growth factors (100 ng/ml IGF-1 or 20 ng/ ml EGF) in combination with one of two antioxidants (50 μM cysteamine or 50 μM beta-mercaptoethanol) in invitro maturation of buffalo oocytes, followed by fertilization and subsequent development of embryos. Materials and Methods: The oocytes were recovered by in vivo ovum pick-up techni...

The oocyte maturation includes nuclear maturation and cytoplasmic maturation before fertilization. Moreover, the oocyte nucleus, the cytoplasm and other cell organelles occur changes, zona pellucida (ZP) synchronously undergoes biochemical and structural modifications in the final maturation phase of oocyte prior to fertilization (ZP maturation). It is reported that ZP modifications, such as gl...

Abstract Background Wheat flour maturation affects the aggregation and structural stability of proteins. The number high-molecular-weight glutenin subunits (HMW-GSs) differs in various wheat varieties. effects Dx2 absence on protein characteristics thermal were investigated during 120 days using near-isogenic lines (NILs). Results delayed decreased flours maturation, i.e., maturation-induced in...

background: human chorionic gonadotropin (hcg) has been used as a replacement for the mid-cycle luteinizing hormone (lh) surge for several years. the recent arrival of recombinant dna technology has made recombinant hcg (rhcg) accessible. objective: to assess efficacy of rhcg compared to urinary hcg (uhcg) for triggering of ovulation and induction of final oocyte maturation in assisted reproduc...

Abstract The objective of this work was to evaluate the effect pre-harvest spraying with aminoethoxyvinylglycine (AVG) and ethephon on fruit maturation 'Baigent' apple (Malus domestica) trees grown under black anti-hail nets. treatments were: control; 125 mg L-1 AVG, sprayed 30 days before anticipated harvest time (DBAH); 120 7 DBAH; 62.5 + AVG 20 DBAH DBAH. Fruit were harvested in commercial c...
