Today, the treatment of patellar luxations using current techniques has become a very common procedureas part of the surgical treatment. Nevertheless, there are some doubts about such procedures in restraining the patella in lower grade cases. The purpose of the present retrospective clinical study was to determine theefficacy of the soft tissue and bone reconstructive procedures used for vario...

Osteoma is an uncommon bone tumor in avian species and other animals. A 2-year-old male canary (Serinus canaria) with a history of an oval mass in the left wing for several months was examined. Radiographs showed a radio-opaque mass. Upon the bird’s owner request, the canary was euthanatized and submitted for necropsy. The histopathologic examination revealed numerous trabeculae consis...

Aluminum is present in very small amounts in living organisms but abundant in the environment. A growing literature links with the biochemistry of aluminum and also with a series of diseases in chronic renal failure patients on treatment with hemodialysis. The initial description of potential aluminum toxicity in renal failure patients relates to description of dialysis encephalopathy syndr...

A man with metastatic carcinoma of the colon had a bone scan which revealed urinary retention in the left kidney. Ten months later, a Tc-99m-DTPA renai glomerular study showed the left kidney to have only 8% of total renal function. Fifteen months after that, (he same kidney demonstrated 9% of total function, while the right kidney had evolving obstruction due to his neoplasm. The case sh...

This is the report of a mandibular neuroectodermal/ewing sarcoma in an 8-year-old male cross breed dogthat is unique because of tumor origin location. Pedunculated, ulcerative, firm 6.0 × 4.0 × 5.5 cm tumor masseffaced the bone at the rostral part of the mandible and had a white-sanguineous color at cross sectionappearance. Histopathologically, small round blue cell tumor was diagnosed. Immunoh...

Introduction: Mesenchymal stem cells (MSCs) hold great promise in the field of regenerative medicine.Although originally isolated from bone marrow, MSCs have since been obtained from a variety of adult and neonatal tissues including the adipose tissue. Stemness and multipotential features of Mesenchymal Stem Cells (MSC) has been highlighted in many studies but there are many dark aspects in ex...

let $m_r$ be a module with $s=end(m_r)$. we call a submodule $k$ of $m_r$ annihilator-small if $k+t=m$, $t$ a submodule of $m_r$, implies that $ell_s(t)=0$, where $ell_s$ indicates the left annihilator of $t$ over $s$. the sum $a_r(m)$ of all such submodules of $m_r$ contains the jacobson radical $rad(m)$ and the left singular submodule $z_s(m)$. if $m_r$ is cyclic, then $a_r(m)$ is the unique ...

Introduction: Brachytherapy is the use of small encapsulated radioactive sources in close vicinity of tumors. Various methods are used to obtain the dose distribution around brachytherapy sources. TG-43 is a dosimetry protocol proposed by the AAPM for determining dose distributions around brachytherapy sources. The goal of this study is to update this protocol for presence of bone and air inhom...
