Compact objects occupy a pivotal role in the exploration of Nature. The interest spans from compact astrophysics to their detection through various methods (gravitational waves interferometry, microlensing, imaging). While existence made fermions (neutron stars and white dwarfs) has been assessed, parallel search for localized solitons bosons is ongoing, stemming Wheeler's original proposal ele...

STUDY DESIGN Retrospective study. PURPOSE To note the magnetic resonance imaging (MRI) differences between pathologically proven cases of atypical spinal tuberculosis and spinal metastasis in 40 cases. OVERVIEW OF LITERATURE Spinal tuberculosis, or Pott's spine, constitutes less than 1% of all cases of tuberculosis and can be associated with a neurologic deficit. Breast, prostate and lung c...

Key Practice Points: • Upper limb entrapment neuropathies can present clinically similar to various musculoskeletal conditions. • History, physical examination, and electrodiagnostic studies alone do not always accurately identify the correct diagnosis. • The practioner’s ability to employ a combination of neuromuscular and musculoskeletal ultrasound can be a powerful adjuvant to clinical and e...

The inclusion of the Weyl squared term in gravitational action is one most simple, yet non trivial modifications to General Relativity at high energies. Nevertheless study spherically-symmetric vacuum solutions this theory has received much attention only recent times. A new type asymptotically flat wormhole which does not match symmetrically a finite radius with another sheet spacetime present...

background : gastric cancer is a common and lethal disease throughout the world. in iran with 7300 new cases annually, it is the first cause of cancer related death in both sexes. regarding the high incidence (10.5/100000 individuals) of gastric can­cer and priority of prevalence index in cancer management, in this study we tried to determine 1, 2-3 and 4-5 year point preva­lence of the disease...

We are summarizing some of the difficult pitfalls in tumors of the head and neck, which we have encountered in our biopsies referred for consultation as well as from our routine praxis in the last 20 years. Shortly we are presenting the following lesions of head and neck: multifocal sclerosing thyroiditis, mucoepidermoid carcinoma of the thyroid, solid cell nests, Chievitz organ, rhomboid gloss...

introduction raman spectroscopy is a vibrational spectroscopic technique, based on inelastic scattering of monochromatic light. this technique can provide valuable information about biomolecular changes, associated with neoplastic transformation. the purpose of this study was to find raman spectral markers for distinguishing normal samples from cancerous ones in different tissues. materials and...

Primary mediastinal large B-cell lymphoma (PMLBL) is an uncommon non-Hodgkin lymphoma with a distinct clinicopathological entity in the WHO classification of lymphoid malignancies. It is known to originate from B-cells of the thymus. It mimics thymic neoplasms and other lymphomas clinically and histopathologically. We reported a 33-year-old obese man who presented with shortness of breath off a...
