In silico search, characterization and validation of new EST-SSR markers in the genus Prunus

BackgroundSimple sequence repeats (SSRs) are defined as sequence repeat units between 1 and 6 bp that occur in both coding and non-coding regions abundant in eukaryotic genomes, which may affect the expression of genes. In this study, expressed sequence tags (ESTs) of eight Prunus species were analyzed for in silico mining of EST-SSRs, protein annotation, and open reading frames...

Total regression of brain metastases in non-small cell lung cancer patients harboring EGFR mutations treated with gefitinib without radiotherapy: two case reports

Background Gefitinib is an epidermal growth factor receptor tyrosine kinase inhibitor. Clinical trials have reported its effectiveness in the treatment of brain metastases from non-small cell lung cancer by overcoming the blood–brain barrier. Gefitinib is generally regarded as a relatively safe agent, and several reports have described its efficacy in patients with epidermal...

Intravesical migration of an intrauterine device

Background Intrauterine contraceptive device is the most common method of reversible contraception in women. The intrauterine contraceptive device can perforate the uterus and can also migrate into pelvic or abdominal organs. Perforation of the urinary bladder by an intrauterine contraceptive device is not common. In West Africa, intravesical migration of an intrauterine...

A case of treatable hypertension: fibromuscular dysplasia of renal arteries

Background Renovascular hypertension accounts for 51–52 % of all cases of hypertension in the general population, but plays a major role in treatable causes for hypertension in the young. This entity consists of renal vascular atherosclerosis (90 %), commonly seen among the elderly population, and renal fibro muscular dysplasia (FMD) (10 %), predominantly seen in the young. The...

20p12.3 deletion is rare cause of syndromic cleft palate: case report and review of literature
