The work presented in this paper is part of the study which aims at determining the levels of elements in hair of children in Tanzania as a bioindicator of their nutrition and health. In this paper, the levels of trace elements in hair from children living in Dar es Salaam have been analysed. The analysis was carried out by long and short irradiation INAA at the reactor centre of the Institute ...

A 65-year-old woman presented with left facial involuntary movement and facial palsy for eight years. Brain magnetic resonance image (MRI) and magnetic resonance angiography (MRA) revealed multiple vascular compression of facial nerve root exit zone (REZ). Standard retromastoid suboccipital craniectomy and arachnoid dissection were performed. Right vertebral artery (VA), left VA, left anterior ...

This study aimed at determining the prevalence of INK4 deletions and their impact on outcome in 125 children with acute lymphoblastic leukemia (ALL) at first relapse using real-time quantitative polymerase chain reaction. Patients were enrolled into relapse trials ALL-REZ BFM (ALL-Relapse Berlin–Frankfurt–Münster) 90 and 96. The prevalence of p16INK4a and p15INK4b homozygous deletions was 35% (...

In this article, turbulent flow heat transfer in the air gap between rotor and stator of a generator under nonhomogeneous heat flux is studied experimentally. The rotor consists of four symmetrical triangular grooves. The stator surface is smooth and does not include any grooves. The relative heat flux between the rotor and the stator is 1 to 3. Temperature and heat flux are measured locally at...

Sacral chordoma presents a difficult diagnostic and therapeutic problem, with diffucult differantion of malign and bening lesion. An 66year-old male, presented with a history of back-lower extremity pain and leg weakness. MRI demonstrated a mass, which measured 10x10x15 cm, was located in front of the sacrum so as to compress the rectum forward. The patient was referred to our positron emission...

Trigeminal neuralgia (TN) is a common pain syndrome and is characterized by recurrent episodes of intense lancinating pain in one or more divisions of the trigeminal nerve. Neurovascular compression (NVC) has been considered as the main cause of TN in the root entry zone (REZ) of the trigeminal nerve in the cerebellopontine angle cistern. Microvascular decompression (MVD) is the surgical proced...

A fundamental domain D for T2 is a connected closed subset D c H behaving like the quotient space T2 \ H, at least up to boundary identifications. Thus, for every z g H, there is a y G T2 such that yz g D. Moreover, if z and w lie in the interior of D and z = yw for y G T2, then y = ±1, where / is the identity matrix. It is easily seen (cf. Terras [17]) that the region (1.1) F2= (zg//| -i< Rez<...

Trigeminal neuralgia (TN), a neuropathic disorder of one or both of the trigeminal nerves, occurs most often in people over age 50. Extreme, sporadic, sudden burning or shock-like face pain in common activities greatly lowers quality of life. The precise cause of primary TN remains unknown, but it may be caused by vascular pressing on the trigeminal nerve in its root entry zone (REZ), demyelini...
