conclusions donor site pain following autologous iliac crest bone harvest is a common surgical complication that is often resistant to conservative treatments such as physical therapy and oral medications. blockade of the superior cluneal nerves is a safe and technically simple procedure that may result in long-term pain relief, obviating the need to consider more invasive options. case present...

background split- thickness skin graft is one of the most common operations in plastic surgery. it is always painful and patient discomfort from donor site often is more significant than recipient site. there is not still a standard method for treatment of the donor site. the purpose of this study was to determine the best method of dressing the donor site among three different methods with res...

patients and methods from march 1976 to december 2013, the number of patients that underwent living renal transplantation sharing at least one hla haplotype with their donors was 2,485. we divided these patients into two groups: (1) 2,075 kidney transplant recipients (1,554 or 74.9% male and 521 or 25.1% female) for whom the donors were living related, (2) 410 kidney transplant recipients (297 ...

A new T-grafting photosensitizer of Dye-Sensitized Solar Cell (DSSC) has been developed by aligning Donor-Acceptor (D-A) group in an axially chiral BODIPY. Synthesis the dye was conducted over a linear approach involving one-pot, non-oxidative synthesis 1,3,5,7-tetramethyl-8-(o-methoxyphenyl)BODIPY, bromination, and finally C2/C6 ethyl acrylate Pd-Heck coupling to produce 65% 2-ethylacrylic-1,3...

This article reports the design and synthesis of donor-substituted symmetrical and unsymmetrical benzothiadiazoles (BTDs) of 5-12 type D-π-A-D, D1-π-A-D2, D1-A1-A2-D2, D-A1-A2-D and D-A1-A2-A1-D by Ullmann, Suzuki and cycloaddition-retroelectrocyclization reactions. The photophysical, electrochemical and computational properties were studied and show substantial donor-acceptor interaction. Thei...

Three new heteroleptic copper(II) complexes, [(tmen)Cu(dike)H2O]X where tmen = N,N,N',N'-tetramethylethylenediamine, dike = 2-acetylcyclopentanone anion and X= ClO4- (1), Cl- (2) and Br- (3) are prepared and characterized by elemental analyses, molar conductance measurements and IR and UV-Vis spectroscopy techniques. The complex 1 is fairly soluble in various organic solvents and demonstrates d...

Conjugated polymer photocatalysts have received extensive attention in the field of photocatalytic hydrogen evolution owing to their tunable molecular structures and electronic properties. Herein, we developed three donor-acceptor (D-A) type thiophene-containing narrow-band-gap conjugated polymers with pyrene as a donor different fused-thiophene derivatives acceptors via direct C-H arylation co...

introduction: the main purpose of donor selection is not only the donor protection from blood donation complications but also the blood recipient not be expose to blood- transmitted diseases. this study aimed to determine the reason for exemption from donors among blood donor's who refer to ilam blood transfusion organization. materials and methods: this is a retrospective and descriptive ...

Understanding the sources of energy loss in bulk heterojunction (BHJ) solar cells is outstanding importance for increasing power conversion energy. Herein, we employ a full quantum mechanics approach to determine rates charge transfer processes at acceptor–donor interface prototypical BHJ blend. It shown that recombination singlet (CT) state acceptor/donor (A/D) very fast, being most effective ...

background and objectives: hepatitis e virus (hev) is a major public health concern in developing countries. hev transmission occurs primarily by the fecal-oral route. it has also been reported that blood donors are potentially able to cause transfusion-associated hepatitis e in endemic areas. this study aimed to determine the seroprevalence of hev infection among volunteer blood donors in cent...
