OBJECTIVES To examine memory-related EEG power and coherence over temporal and central recording sites in patients with early Alzheimer's disease (AD) and normal controls. METHOD EEG was recorded from central (Fz, Cz and Pz) and temporal (T3 and T4) electrodes while ten very mild AD patients and ten controls performed a Sternberg-type memory scanning task with three levels of working memory l...

A consecutive series of 75 patients with syringomyelia is presented, all of whom were treated by cranio-vertebral operations. Attention is drawn to the difficulty in assessing the results of treatment but 56 stabilised or showed modest improvement after surgery. Occluding the central canal appeared to have no greater influence on the progression of the disease than did simple decompression and ...

BACKGROUND Many methods have been proposed for the correction of sunken upper eyelids. These methods include surgical treatments, such as micro-fat, dermofat, or fascia-fat grafts, or the use of alloplastic materials. Here, we present our experience of sunken upper eyelid correction involving the simple addition of anchoring the central fat pad to the medial fat pad during upper blepharoplasty....

In this article, we consider an insurance risk model where the claim and premium processes follow some time series models+ We first consider the model proposed in Gerber @2,3#; then a model with dependent structure between premium and claim processes modeled by using Granger’s causal model is considered+ By using some martingale arguments, Lundberg-type upper bounds for the ruin probabilities u...

In this paper we prove that the condition 2n ∑ k=[ 2 ] kλk |n− k|+ 1 = o(1) (= O(1)) , for r = 0, 1, 2, . . . , is necessary for the convergence of the r − th derivative of the Fourier series in the L−metric. This condition is sufficient under some additional assumptions for Fourier coefficients. In fact, in this paper we generalize some results of A. S. Belov [1]. AMS subject classifications: ...

Midgut volvulus is a surgical emergency and occurs as a complication in patients with malrotation. The importance of an upper gastrointestinal (UGI) series in all patients with gastroesophageal refl ux (GER) disease is to rule out any anatomic abnormality precipitated by GER. Of these abnormalities, “midgut volvulus” is the most catastrophic complication and occurs with intestinal malrotation a...

Working memory (WM) is a part of human memory, the ability to maintain and manipulate information. WM performance is impaired in some neurological and psychiatric disorders such as schizophrenia and ADHD. Neurofeedback training is a self-regulation method which can be used to improve WM performance by changing related EEG parameters. In this paper we used neurofeedback training to improve WM pe...

This contribution presents and interprets the results of analysis fauna relics from Pustý hrad Castle in Zvolen Central Slovakia. The analysed series comes Upper castle, half 13th to 14th centuries. A total 6082 bone fragments weighing about 28 kg were processed. In addition standard quantification methods (MNI, NISP weight), age animals relative quality meat body parts represented also analyse...
