this study has examined the relationship between the xpd lys 751 gln polymorphism and colorectal cancer in 88 patients and their 88 age and sex-matched controls. genomic dna from peripheral whole blood was extracted using standard method to determine the genotype of subjects with rflp-pcr analysis. although this study shows cancer patients harbor more heterozygous genotype (xpd lys 751 gln) (or...

Lymphangioma is a congenital malformation of the lymphatic system and is thought to result from the failure of the lymphatic system to connect with the venous system. Lymphangioma of the chest wall is a very rare disease entity, and only a few cases have ever been documented in the literature. To the best of our knowledge, there have been few cases of recurrent cavernous lymphangioma after surg...

Complete excision of cutaneous angiosarcoma, which is a rare, vascular, and aggressive tumor, is challenging. Its multifocal nature and propensity for lateral spread make the gross assessment of surgical margins difficult. Neither the use of frozen section analysis nor Mohs surgery consistently improves the probability of margin-free excision. Recent studies have advocated the use of indocyanin...

Background: Bowen’s disease is a form of intraepidermal squamous cell carcinoma (SCC) characterised by a persistent, non-elevated, red, scaly or crusted plaque with a small potentialfor invasive malignancy. Most cases of typical Bowen’s disease in the white population are found on the lower legs of the elderly women. H...

DNA-protein crosslinks are relatively common DNA lesions that form during the physiological processing of DNA by replication and recombination proteins, by side reactions of base excision repair enzymes, and by cellular exposure to bifunctional DNA-damaging agents such as platinum compounds. The mechanism by which pathological DNA-protein crosslinks are repaired in humans is not known. In this ...

A purified system comprised of MutSalpha, MutLalpha, exonuclease 1 (Exo1), and replication protein A (RPA) (in the absence or presence of HMGB1) supports 5'-directed mismatch-provoked excision that terminates after mismatch removal. MutLalpha is not essential for this reaction but enhances excision termination, although the basis of this effect has been uncertain. One model attributes the prima...

the effect of prepared ayurvedic formulation was evaluated on excision and incision wound models in rats. the wound-healing activity was assessed by the rate of period of epithelialization and skin-breaking strength. histological study of the granulation tissue was carried out to know the extent of collagen formation in the wound tissue. the ayurvedic formulation prepared was then promoted for ...

objective: to compare outcome of patients with burns covering less than 15% of total body surface area(tbsa) undergoing early excision and grafting or delayed skin grafting. method : this was a non-randomized clinical trial including 54 patients with less than 15% tbsa burn referring to ghotboddin hospital of shiraz. they were assigned to two study groups, each group including 27 patients: the ...

DNA probes for the studies of damaged strand excision during the nucleotide excision repair (NER) have been designed using the novel non-nucleosidic phosphoramidite reagents that contain N-[6-(9-antracenylcarbamoyl)hexanoyl]-3-amino-1,2-propandiol (nAnt) and N-[6-(5(6)-fluoresceinylcarbamoyl)hexanoyl]-3-amino-1,2-propandiol (nFlu) moieties. New lesion-imitating adducts being inserted into DNA s...
