annular pancreas (ap) is a rare congenital abnormality in which pancreatic tissue completely surround the duodenum. presentation of ap in adulthood is very rare and obstructive jaundice is one of the uncommon manifestations of ap in adults. herein; we reported a 47 years old woman who presented with icterus, midcommon bile duct stricture and annular pancreas. she was diagnosed as pancreas cance...

Background: A pyogenic granuloma (PG) is a common benign vascular lesion found in the oral cavity. The gold standard treatment of this lesion, comprising surgical excision and elimination etiological factors, cannot avoid tooth loss case an aggressive granuloma. Because prominent properties 980 nm 635 diode lasers photocoagulation photobiomodulation, we applied these wavelengths large wi...

Granulomas play an essential role in the sequestration and killing of mycobacteria in the lung; however, the mechanisms of their development and maturation are still not clearly understood. IL-17A is involved in mature granuloma formation in the mycobacteria-infected lung. Therefore, IL-17A gene-knockout (KO) mice fail to develop mature granulomas in the Mycobacterium bovis bacille Calmette-Gué...

The mode-matching applications to scattering from circular and annular apertures in a thick perfectly conducting plane are reviewed. The Hankel and Weber transforms are utilized to solve the boundary-value problems of circular and annular apertures. Simple electrostatic problems are presented to illustrate the mode-matching method in terms of the Hankel and Weber transforms. Various types of We...

Cholesterol granuloma is a pathological lesion affecting the mastoid air cells due to partial obstruction of its aireation. It is commonly unilateral. It is usually associated with glue ear with intact ossicles. Histologically, it is characterized by the presence of large pointed crystals and giant cells. Its treatment is either conservative steroid therapy or surgical removal of the granuloma ...

PURPOSE To report the clinicopathologic features of a case of conjunctival synthetic fiber granuloma. CASE REPORT A 6-year-old girl presented with a slow-growing red nodule in the right inferior conjunctival sac with no history of surgery or trauma. Histopathological examination revealed foreign body type granulomatous inflammation around birefringent fibers of variable colors consistent with...

Tuberculosis remains a major human health threat that infects one in three individuals worldwide. Infection with Mycobacterium tuberculosis is a standoff between host and bacteria in the formation of a granuloma. This review will introduce a variety of bacterial and host factors that impact individual granuloma fates. The authors describe advances in the development of in vitro granuloma models...

Annular patterns with a high degree of zonal symmetry play a prominent role in the natural variability of the atmospheric circulation and its response to external forcing. But despite their apparent importance for understanding climate variability, the processes that give rise to their marked zonally symmetric components remain largely unclear. Here the authors use simple stochastic models in c...

This paper presents modeling of annular patch antenna. The S and Z parameters of an Annularpatch Microstrip antenna are investigated and optimization. The optimization is performed byvarying the inner and outer radius of annular Ring. The impedance and radiation characteristicsof annular patch antenna are examined and compared. It is able to achieve a return loss lessthan -36 dB...
