the main objective of this study is to swing krull intersection theorem in primary decomposition of rings and modules to the primary decomposition of soft rings and soft modules. to fulfill this aim several notions like soft prime ideals, soft maximal ideals, soft primary ideals, and soft radical ideals are introduced for a soft ring over a given unitary commutative ring. consequently, the p...
extramedullary plasmacytoma (emp) is a rare neoplasm of soft tissue which usually arises in the respiratory tract, nasal cavity, sinuses and nasopharynx. multiple extramedullary plasmacytomas are extremely rare, especially those that are not associated with multiple myeloma.we describe multiple primary emp in a 37 year old man, without involvement of bone or bone marrow. emp usually has a good ...

An M-polysymmetrical hyperring $(R,+,cdot )$ is an algebraic system, where $(R,+)$ is an M-polysymmetrical hypergroup, $(R,cdot )$ is a semigroup and $cdot$ is bilaterally distributive over $+$. In this paper, we introduce the concept of hyperideals of an M-polysymmetrical hyperring and by using this concept, we construct an ordinary quotient ring. Finally, the fundamental theorem of homomorphi...

objective(s):glaucoma is the second leading cause of blindness and it is related to oxidative stress based on numerous studies. glutathione s-transferases (gsts) are members of multigenic family, which have important role in cells as an antioxidant. in the present study, we examined the polymorphism of gstt1 and gstm1 deletion genotypes (t0m1, t1m0, and t0m0) in 100 glaucoma patients (41with pr...
hyperparathyroidism is an endocrine abnormality that frequently causes diffuse osteopenia in the bones. osteosclerosis is a rare phenomenon in adults with primary hyperparathyroidism since the usual skeletal manifestation is generalized osteopenia. we describe a patient with generalized osteosclerosis in the jaws and skull in association with primary hyperparathyroidism, while the other skeleta...
introduction: lymphoma may involve the gastrointestinal tract either primarily or as a manifestation of extensively disseminated systemic disease. stomach being the most frequent site of primary gastroin-testinal lyphoma, followed by the small bowel and colon respectively (1&2&3). for diagnosis of pi-mary small intestinal lymphoma (psil), one most satisfies the criteria specified by dawson and ...
