The stimuli-responsive nanocomposites were designed as drug delivery nanocarriers. Thanks to promising properties such as large surface area and easy chemical functionalization, the graphene derivatives can be used for the drug delivery applications. For this purpose, in the current work, the poly(L,D-lactide)-block-poly(N-isopropylacrylamide-rand-acrylic acid) grafted from reduced graphene oxi...

Ten dogs were given 9.2 Gy of total body irradiation and autologous bone marrow infusion followed by ten daily transfusions of leukocytes for a total of 11.5 to 36.2 (median, 18.8) x 10(8)/kg obtained via leukapheresis from histoincompatible unrelated donors. Four dogs were given unirradiated leukocytes, and all developed graft-versus-host disease (GVHD). In contrast, only two of three dogs giv...

OBJECTIVE To investigate the efficacy, potential limitations, and biological mechanisms of UV-A1 phototherapy for skin sclerosis due to collagen deposition disorders. DESIGN Before-and-after trial of UV-A1 irradiation of sclerotic skin; in vivo biochemical analyses after UV-A1 irradiation of normal skin. SETTING Academic referral center. PARTICIPANTS Patients with morphea/scleroderma or s...

To investigate the clinical applicability of prophylaxis of post-transplant graft-versus-host disease by UV-B irradiation of stem cell preparations, the UV-B sensitivities of human lymphocytes and primitive hematopoietic progenitors were compared. The mononuclear cell fractions (MNC) derived from human cord blood and granulocyte-colony-stimulating factor-mobilized peripheral blood were used. Af...

IMPORTANCE Chronic graft-vs-host disease (GVHD) affects 50% to 70% of patients who receive allogeneic hematopoietic cell transplants (HCTs), and the skin is the most common site of involvement. Chronic cutaneous GVHD can present with sclerotic or nonsclerotic changes of the skin and often requires treatment with systemic immunosuppressants, extracorporeal photopheresis, or phototherapy. We desc...

Clinical studies have revealed a correlation between cytomegalovirus (CMV) infection and acute allograft rejection. Likewise, for a murine model we observed that C3H (H-2k) recipients infected with murine CMV (MCMV) rejected BALB/c (H-2d) cardiac allografts earlier than uninfected recipients (6.9 +/- 0.1 d compared with 8.1 +/- 0.6 d; P < 0.001). It has been hypothesized that MCMV epitopes cros...

The UV radiation method is a suitable method for grafting processes . Poly-Nisopropylacrylamide was successfully grafted onto a polystyrene surface with benzophenone initiator under UV radiation. The ATR-FTIR analysis showed the existence of the graft poly-N-isopropylacrylamide (PNIPAAm) on the surface by this method. The scanning electron microscopy and atomic force microscopy (AFM) images cle...
