INTRODUCTION: Neoadjuvant chemotherapy has become the treatment of choice for locally advanced breast cancer. Zoledronic acid (ZA) is a bisphosphonate initially used in the treatment of bone metastases because of its antibone resorption effect. Antitumor effects of ZA, including the inhibition of cell adhesion to mineralized bone or the antiangiogenic effect, have been demonstrated. However, the clinical significance of these effects remains to be determined. MATERIALS AND METHODS: We undertook a multicenter open-label randomized trial to analyze the value of adding ZA to neoadjuvant chemotherapy for TNM clinical stage T2/T3 breast cancer...

Primary hyperparathyroidism is an endocrine disorder occurring due to increased secretion of parathormone resulting in a complex of clinical, anatomical, and biochemical alterations. On the other hand, excision of a parathyroid adenoma can normalize the metabolic status. A 24-year-old man was referred to the hospital with bilateral swelling and spontaneous gingival bleeding from posterior of the mandible also with radiolucent well-demarcated lesions bilaterally in the mandibular third molar regions. After consultations, the patient was hospitalized in the endocrinology department where further tests were performed due to highly increased PTH level as 714 pg/ml...

T-cell/histiocyte-rich large B-cell lymphoma (THRBCL) is an uncommon subtype of non-Hodgkin's lymphoma. It is a predominant nodal neoplasm; however, extranodal sites, such as the spleen, liver and bone marrow, can be involved at diagnosis. However, only one case of primary THRLBCL in the jaws have been reported. We herein describe a 29-year-old female patient who presented with a swelling of the right mandible that had grown rapidly over the previous 2 months. Periapical and panoramic radiographs showed a multilocular osteolytic lesion located in the mandibular periapical region of the canine and premolar teeth and molar region...

Glioblastoma Multiforme (GBM) is the most malignant and invasive tumor of the CNS. Although temozolomide (TMZ) has improved the survival, long-lasting responses have not been reported. Therefore, there is a need to develop improved treatments, one of which might be newly identified drugs which can be used in combination therapy with low doses of standard drugs. Verapamil (VP) a known antihypertensive drug has been shown to enhance the activity of bis-chloroethylnitrosourea (BCNU), a drug used to treat GBM. Since, TMZ has replaced BCNU as the standard GBM chemotherapy; therefore, we aimed to study in vitro interaction of VP and TMZ against GBM...

Mucoepidermoid carcinoma (MEC) is the most common malignant tumor of the salivary glands and is seen most commonly in the parotid gland. Intraosseous MECs can be rarely seen and is mostly detected in the posterior part of the mandible. This condition can be acknowledged as an entity different from salivary gland MECs. In this case series, we delineated three patients of intraosseous MEC, two mandible tumors and one maxillary tumor and discussed the diagnostic characteristics and treatment methods of this rare entity...

Benign epithelial odontogenic lesions are great clinical importance entities that develop in the jaws from the tissues that form teeth. It has been shown that benign and malignant tumors are present in a large number of tumor stem cells, which has great implications in the development of these lesions. Oct-4 and CD44 have been demonstrated as important markers for tumoral stem cells. The aim of this study was investigate the presence of stem cell markers Oct-4 and CD44 in benign epithelial odontogenic lesions...

Ameloblastoma is a locally aggressive common odontogenic tumor of the jaws. Although histopathological and radiological findings have been extensively studied for the diagnosis of ameloblastoma, usefulness of fine-needle aspiration cytology (FNAC) has not been explored much. Here, we have reported four cases of ameloblastomas diagnosed by FNAC and subsequently confirmed by histopathology.

Class III mandibular resection due to surgical treatment of jaw tumor produces a discontinuity in the mandible which is severely incapacitating to the patient. It leads to a deviation and rotation of the mandible which depends on the amount of tissues resected the manner of surgical site closure, loss of proprioceptive sense of occlusion, the presence, and condition of teeth, and the time of initiation of prosthodontic therapy. These put together makes the task of prosthodontic rehabilitation quite arduous...

Most ligands and receptors from the tumor necrosis factor (TNF) superfamily play very important roles in the immune system. In particular, many of these molecules are essential in the regulation of B cell biology and B cell-mediated immune responses. Hence, in mammals, it is known that many TNF family members play a key role on B cell development, maturation, homeostasis, activation, and differentiation, also influencing the ability of B cells to present antigens or act as regulators of immune responses. Evolutionarily, jawed fish (including cartilaginous and bony fish) constitute the first animal group in which an adaptive immune response based on B cells and immunoglobulins is present...

Among oral pathologic lesions, odontomas are the most common odontogenic tumor of the jaws and generally asymptomatic. They are mostly diagnosed as a result of routine radiographic investigation. In this report, we describe a very rare occurrence of bilateral complex odontoma in the region of the mandibular second premolar. Conservative surgical procedure was planned, and removal of the odontomas was carried out through the socket after extraction of the deciduous second molars, and the diagnosis was confirmed with a histopathological study...

Rationale: Increasing frequency of human exposure to PEG-related products means that healthy people are likely to have pre-existing anti-PEG antibodies (pre-αPEG Ab). However, the influence of pre-αPEG Abs on the pharmacokinetics (PK) and therapeutic efficacy of LipoDox is unknown. Methods: We generated two pre-αPEG Ab mouse models. First, naïve mice were immunized with PEGylated protein to generate an endogenous αPEG Ab titer (endo αPEG). Second, monoclonal αPEG Abs were passively transferred (αPEG-PT) into naïve mice to establish a αPEG titer...
