Vitamin D3: 1-alpha, 25(OH)2D3 (calcitriol), 22-oxa-1,25(OH)2D3 (OCT), cholecalciferol (vitamin D3), and retinoids: all-trans retinoic acid (ATRA) and 9-cis retinoic acid, induced morphological changes in POS canine osteosarcoma cells into elongated, spindle or fibroblast like-shaped cells, and apoptotic like cell death characterized by cell shrinkage, condensation and margination of the nucleu...

CPC solar collectors are a combination of new technologies that make it possible to generate heat from radiant energy by transferring between the absorber and fluid. This study was performed based on transfer equations proposing mathematical model, as reported in literature. A compound parabolic concentrators collector (CPC) numerical model simulated coded Aspen HYSYS MATLAB software validated ...

The tail of bacteriophage T4 consists of a contractile sheath surrounding a rigid tube and terminating in a multiprotein baseplate, to which the long and short tail fibers of the phage are attached. Upon binding of the fibers to their cell receptors, the baseplate undergoes a large conformational switch, which initiates sheath contraction and culminates in transfer of the phage DNA from the cap...

OBJECTIVE Oxaliplatin, a key part of the standard regimen for colorectal cancer in Western countries, has become available in Japan. In a hemodialysis patient with cecal cancer, we investigated the efficacy, safety, pharmacokinetics, and dialysability of oxaliplatin. METHODS A 65-year-old man who had cecal cancer was treated with oxaliplatin (40 mg/m(2)) and l-leucovorin(l-LV) (200 mg/m(2)), ...

We calculate the coherent dynamical scattering function S(c)(q,t;N) of a flexible chain of length N, diffusing through an ordered background of topological obstacles. As an instructive generalization, we also calculate the scattering function S(c)(q,t;M,N) for the central piece of length M<or=N of the chain. Using the full reptation model, we treat global creep, tube length fluctuations, and in...

A new species, Melampyrum koreanum K.-J. Kim & S.-M. Yun, is described and illustrated. The new species is similar to M. roseum Maxim. in general habit, but the new species has a corolla tube and style up to 3 cm long. The new species occurs on one of the islands of the southern Korean peninsula.

chest tube (ct) or tube thoracostomy placement is often indicated following traumatic injuries. premature movement of the chest tube leads to increased hospital complications and costs for patients. placement of a chest tube is indicated in drainage of blood, bile, pus, drain air, and other fluids. although there is a general agreement for the placement of a chest tube, there is little consensu...

NADH concentration will produce an upward curve deflection. Bubble traps have been inserted prior to the pumps on the NADH reagent lines. The trap has been constructed from an Y-shaped glass tube, mounted upside-down, with its top connected to a piece of soft polyethylene tube, closed by a clamp. This tube will collect bubbles. Each morning, it must be refilled with fresh reagent by aspiration....

Much of the excitement surrounding new carbon nanomaterials can be traced to their directional properties, which arise through precise orientation of graphene layers that are the anisotropic building blocks of all sp-hybridized carbon forms. The high conductivity, strength, and stiffness of carbon nanotubes are directly related to the parallel orientation of graphene layers relative to the tube...
