The long term prognosis of liver cancer patients remains unsatisfactory because of cancer recurrence after surgical interventions, particularly in patients with viral infections. Since hepatitis B and C viral proteins lead to inactivation of the tumor suppressors p53 and Retinoblastoma (Rb), we hypothesize that surgery in the context of p53/Rb inactivation initiate de novo tumorigenesis.We, the...

The retinoblastoma protein (Rb) acts as a critical cell-cycle regulator and loss of Rb function is associated with a variety of human cancer types. Here we report that Rb binds to members of the AP-1 family of transcription factors, including c-Jun, and stimulates c-Jun transcriptional activity from an AP-1 consensus sequence. The interaction involves the leucine zipper region of c-Jun and the ...

PURPOSE To examine whether bone marrow mesenchymal stem cells (MSCs) could be differentiated into corneal epithelial cells in vivo and ex vivo. METHODS In vivo, BrdU labeled rabbit MSCs (Rb-MSCs) were suspended in the fibrin gels and transplanted onto the surface of the damaged rabbit corneas. Histology and molecular phenotype were studied on postoperative day 28. In vitro, labeled Rb-MSCs we...

We consider a branching random walk (BRW) taking its values in the b-ary rooted tree Wb (i.e. set of finite words written alphabet {1,…,b}, with b≥2). The BRW is indexed by critical Galton–Watson conditioned to have n vertices; offspring distribution aperiodic and domain attraction γ-stable law, γ∈(1,2]. jumps are those nearest-neighbour null-recurrent on (reflection at root otherwise: probabil...

Previous studies have shown that a synthetic multivulva phenotype results from mutations in genes that antagonize the ras-mediated intercellular signaling system responsible for vulval induction in Caenorhabditis elegans. Synthetic multivulva mutations define two classes of genes, A and B, and a mutation in a gene of each class is required to produce the multivulva phenotype. The ectopic vulval...

A novel, fluorescent chemosensor based on β-(2-pyridyl)acrolein-rhodamine B (RB-AC) derivative was synthesized and its sensing performance with poly(ethylene glycol) dimethacrylate (PEGDMA) polymer particle was investigated. The prepared β-(2-pyridyl)acrolein-rhodamine B/poly(ethylene glycol)dimethacrylate (PEGDMA/ RB-AC) particle was used for sensing of Al3+. The PEGDMA/RB-AC particles showed ...

The European species of the genera Amblyscelio and Baryconus are reviewed and revised based on morphological data. Females of Amblyscelio striaticeps Kieffer, 1913 and Baryconus graeffei (Kieffer, 1908) are described and the ovipositor of Amblyscelio is illustrated for the first time. The monotypic genus Amblyscelio was previously known only from a single male specimen. Baryconus graeffei is co...

Sequence-dependent coordination of alkali ions to the nucleotide bases in the minor groove of AT-tract B-DNA has recently been inferred from X-ray crystallography, solution NMR and computer simulations. Here, we present new (23)Na and (87)Rb magnetic relaxation dispersion (MRD) data that demonstrate competitive and long-lived binding of Na(+) and Rb(+) ions in the minor groove of the B-DNA dupl...

Previous research has demonstrated that aggression (AGG) and non-aggressive rule-breaking (RB) represent elements of antisocial behavior with different etiological mechanisms and associations to personality and psychopathology. However, these constructs have not been investigated in an adult clinical sample. In the current study, interview and self-report derived AGG and RB were associated with...
