An 18-year-old man was referred to the authors' institution's thoracic cancer specialists for further consultation after abnormal findings were seen on chest radiograph.

Brown tumour represents a serious complication of hyperparathyroidism. Differential diagnosis, based on histological examination, is only presumptive and clinical, radiological and laboratory data are necessary for definitive diagnosis. Here we describe a case of a brown tumour localised in the maxilla due to secondary hyperparathyroidism in a young women with chronic renal failure. Hemodialysi...

Recently observational data indicates that the discrepancy arises at late time, when the age of the universe is some billions years. In this context the Friedmann-RobertsonWalker model is a unique correspondence between the expansion rate and the distance scale. Although general theory of relativity (GTR) is the most suitable theory for describing universe as a whole, but still there are some p...

It is shown some exact solutions in the Brans-Dicke (BD) theory for a Bianchi V metric having the property of inflationary expansion, graceful exit, and asymptotic evolution to a Friedmann-Robertson-Walker (FRW) open model. It is remarkable that an inflationary behaviour can occur, even without a cosmological potential or constant. However, the horizon and flatness problems cannot be solve with...

We investigate cosmological evolutions of the bulk scalar field φ(t) and the radion d(t) in five-dimensional dilatonic two branes model. The bulk potential for the scalar field is taken as the exponential function Vbulk ∝ exp(−2 √ 2bφ), where b is the parameter of the theory. This model includes Randall-Sundrum model (with b = 0) and fivedimensional Hořava-Witten theory (with b = 1). We conside...

Ureteritis cystica is characterized by formation of multiple cysts in the wall of the renal pelvis or ureter. The clinical course is usually slow, but manifests if the cysts cause infection or obstruction. Stones are further complication to the disease. In this case study, we present a 39-year-old male originally referred with renal colic and misdiagnosed as ureterolithiasis due to the calcifiy...

We study the cosmology of the Brans-Dicke(BD) theory coupled to perfect fluid type matter. In our previous works, the case where matter is coming from the Ramond-Ramond sector of the string theory was studied. Here we study the case where matter is coming from NS-NS sector. Exact solutions are found and the cosmology is classified according to the values of γ,the parameter of the equation of st...
