Chronic myeloid leukemia (CML) is a neoplasia characterized by proliferation of a myeloid cell lineage and chromosome translocation t(9;22) (q34;q11.2). As in the case of most cancers, the average telomere length in CML cells is shorter than that in normal blood cells. However, there are currently no data available concerning specific individual telomere length in CML. Here, we studied telomere...

Due to the low solubility of poly(glycolic acid) (PGA), its use is generally limited to the synthesis of random copolyesters with other hydroxy acids, such as lactic acid, or to applications that permit direct processing from the polymer melt. Insolubility is generally observed for PGA when the degree of polymerization exceeds 20. Here we present a strategy that allows the preparation of PGA-ba...

BACKGROUND To assess the influence of the prosthetic arm length (palatal position) of zygomatic implants upon patient comfort and stability, speech, functionality and overall satisfaction. MATERIAL AND METHODS A retrospective clinical study was made of patients subjected to rehabilitation of atrophic maxilla with complete maxillary implant-supported fixed prostheses involving a minimum of two...

[Purpose] This research analyzed how seat distance and gender affect maximal torque and muscle strength when driving to present base data for the optimal driving posture. [Subjects and Methods] The subjects were 27 college students in their 20's, 15 males and 12 females. After had been measured, the subjects sat in front of a steering wheel with the distance between the steering wheel and the s...

Purpose This study evaluates the role of liposomal bupivacaine in implant-based breast reconstruction. Methods A prospective, randomized, single-blind trial of liposomal bupivacaine in implant-based breast reconstruction was performed. Patients in the control arm were treated with 20 mL 0.25% bupivacaine with epinephrine 1:200,000 to each breast pocket. Patients in the experimental arm were t...

BACKGROUND Ethanol lock therapy (ELT) with systemic antimicrobial therapy is a promising therapy for catheter-related infection (CRI). The impact of ELT timing on treatment efficacy and costs is unknown. PROCEDURES A prospective study was conducted in the Hematology/Oncology Unit at the Children's Hospital of Michigan. Patients with suspected CRI were randomized to Preemptive ELT arm or Rescu...

The porpose of this study was to determine the optimal length of power arms for achieving controlled anterior tooth movement in segmented arch mechanics combined with power arm. A three-dimensional finite element method was applied for the simulation of en masse anterior tooth retraction in segmented power arm mechanics. The type of tooth movement, namely, the location of center of rotation of ...

The contractile properties of the transverse muscle of the tentacles and the transverse muscle of the arms of the squid Loligo pealei were investigated using small muscle fibre bundle preparations. In addition, transmission electron microscopy was used to measure the length of the thick myofilaments of the two muscle fibre types. The thick filament length of the cross-striated tentacle fibres w...

BACKGROUND Telomere dysfunction is involved in the development of breast cancer and very short telomeres are frequent genetic alterations in breast tumors. However, the influence of telomere lengths of specific chromosomal arms on the breast cancer risk is unknown. METHODS We conducted a case-control study of breast cancer to examine the associations of the telomere length on chromosome 9 sho...

The arm’s length principle states that the transfer price between two associated enterprises should be the price that would be paid for similar goods in similar circumstances by unrelated parties dealing at arm’s length with each other. This paper examines the effect of the arm’s length principle on dynamic competition in imperfectly competitive markets. It is shown that the arm’s length princi...
