Ocular complications in live-related renal transplant recipients: A single-centre study.

Renal transplantation is considered to be the treatment of choice for patients with end-stage kidney failure. While transplantation has a high success rate, there are a number of associated challenges which include those related to the primary disease, transplant procedure as well as medications that are necessary to take after transplantation. Steroids, for instance, have been reported to lead to ocular complications in patients who have undergone renal transplantation in other parts of the world.

'Candidatus Phytoplasma omanense', associated with witches'-broom of Cassia italica (Mill.) Spreng. in Oman.

Samples from plants of Cassia italica exhibiting typical witches'-broom symptoms (Cassia witches'-broom; CWB) were examined for the presence of plant pathogenic phytoplasmas by PCR amplification using universal phytoplasma primers. All affected plants yielded positive results. RFLP analyses of rRNA gene products indicated that the phytoplasmas detected were different from those described previously.

A divergent isolate of tomato yellow leaf curl virus from Oman with an associated DNA beta satellite: an evolutionary link between Asian and the Middle Eastern virus-satellite complexes.

Tomato is cultivated in the coastal region of Al-Batinah, in the Sultanate of Oman, during the winter season, to meet the high demand for fresh produce in the domestic market. In order to identify the causal agent of a widespread disease associated with infestations of the whitefly Bemisia tabaci (Genn.) leaves were collected from tomato plants showing symptoms characteristic of the disease in Al-Batinah during 2004 and 2005.

Prevalence of diabetic retinopathy among individuals screened positive for diabetes in five community-based eye camps in northern Karachi, Pakistan.

Background: Population-based data on the prevalence of diabetic retinopathy in Pakistan are lacking. We determined the prevalence of diabetic retinopathy among individuals screened positive for diabetes in five community-based eye camps in northern Karachi, Pakistan.

Methods: In summer 2002, five community-based eye camps were set up in Karachi, Pakistan's largest city.
