Large areas of the Central European country Austria are known to be endemic for tick-borne encephalitis virus (TBEV). However, so far only limited data are available for the prevalence, distribution and species composition of rickettsiae of the spotted fever group in Austria. In the present study 306 ticks were collected in summer 2007.

Methods: The medical records of 817 patients who underwent operations for Graves' disease (GD) (n= 342), toxic multinodular goiter (TMG) (n = 299), and toxic adenoma (TA) (n = 176) between January 1988 and April 2006 were reviewed.
Results: Cold nodules were found in 293 (36%) of the patients, and 524 (64%) patients had no cold nodules.
Background: Although total thyroidectomy is the procedure of choice in patients with thyroid carcinoma, this surgical approach has emerged as a surgical option to treat patients with benign multinodular goiter (BMNG), especially in endemically iodine-deficient regions. The aim of this study was to review our experience with patients with BMNG in an endemically iodine-deficient region treated by either subtotal or total/near-total thyroidectomy, and to document whether total or near-total thyroidectomy decreased the rate of completion thyroidectomy for incidentally diagnosed thyroid carcinoma in comparison to the patients with BMNG treated initially by subtotal thyroidectomy.
Methods: Two thousand five hundred ninety-two patients with BMNG were included.
Objective: This study aimed to compare the impact of total versus subtotal thyroidectomy on calcium metabolism and bone mineral density in euthyroid, premenopausal women.
Subjects: The study included 24 premenopausal women who had undergone total (n = 10) or subtotal (n = 14) thyroidectomy and who were receiving nonsuppressive doses of thyroxine. The median post-operative period was four years.
The aim of this study was to investigate the performance of minor salivary gland biopsy (MSGB), serological and clinical data in diagnosis of primary Sjögren's syndrome (pSS). Retrospective review of 216 patients who underwent minor labial salivary gland biopsy in last 5 years was performed. Results of the patients with diagnosis of pSS were compared with the patients failing to fill the classification criteria of pSS.
View Article and Find Full Text PDFAging is associated with many physiological changes in a variety of organ systems. Nevertheless, considerable interest has centred on the possibility that age-related immunological changes may play a key "master" role in regulating many, if not all, subsequent events. A growing body of data, some of it highlighted in this review, supports the notion that host resistance in general is changed in both a qualitative and quantitative manner with age, though the biochemical mechanism(s) underlying such changes are not unique to the immune system per se.

Male Wistar rats divided into five experimental groups of eight animals each: (a) control group; (b) EWS (saline) group; (c) escitalopram 2.5 mg group; (d) escitalopram 5mg group and (e) escitalopram 10 mg group.

The successional stages were mapped using the combination of Geographic Information System (GIS), Global Positioning System (GPS), aerial photos and high resolution satellite images (IKONOS). Forest structure and its relationship with structural plant diversity along with its changes over time were characterized using FRAGSTATS.

Methods: Thirty-three patients scheduled for CT for thyroid carcinoma were randomly selected for 2 types of intervention. CT was performed by RGS following administration of 5 mCi technetium-99m in 15 patients (group 1) and with conventional surgical exploration without RGS in 18 patients (group 2).
This paper explains briefly the conceptual framework of an ecosystem-based multiple-use forest management planning focusing on biodiversity conservation and participation. Some results from a case study were documented to realize the implementation of the concept. A strong liaison between the related institutions and major stakeholders and the effective use of Geographic Information System (GIS) and Remote Sensing (RS) are necessary.

Anti-TNF antibodies such as infliximab, etanercept and adalimumab are commonly used. There are structural and functional differences among these agents.

Previous studies reported antineutrophil cytoplasmic antibody (ANCA)-positive vasculitis in patients treated for Graves' disease. ANCA has been associated with either PTU or to the disease itself.

The etiology of PD is probably a combination of environmental and genetic factors. Recent progress in molecular genetics has identified several genes causing PD, including alpha-synuclein, leucine-rich repeat kinase 2 (LRRK2), Parkin, DJ-1 and PTEN-induced kinase 1 (PINK1), many of them coding for proteins found in LBs and/or implicated in mitochondrial function.

In this study we measured the extracellular levels of GABA and L-glutamic acid in the dorsomedial hypothalamic nucleus (DMH) and posterior hypothalamus (PH), following intracerebroventricular (i.c.

A pathogenic mtDNA mutation causes respiratory chain deficiency only if the fraction of mutated mtDNA exceeds a certain threshold level. These mutations often undergo apparently random mitotic segregation and the levels of normal and mutated mtDNA can vary considerably between cells of the same tissue.

Random neural network (RNN) is an analytically tractable spiked neural network model that has been implemented in software for a wide range of applications for over a decade. This paper presents the hardware implementation of the RNN model. Recently, cognitive packet networks (CPN) is proposed as an alternative packet network architecture where there is no routing table, instead the RNN based reinforcement learning is used to route packets.

Increasing age in mammals correlates with increased levels of mitochondrial DNA (mtDNA) mutations and deteriorating respiratory chain function. Mosaic respiratory chain deficiency in a subset of cells in various tissues, such as heart, skeletal muscle, colonic crypts and neurons, is typically found in aged humans.

Methods: USG-guided FNAB and DCE-MRI were performed consecutively on 26 patients who had multinodular goiter with dominant nodules and clinical suspicion of malignancy. DCE-MRI findings, cytodiagnosis, and final histopathologic results were correlated.
Alternaria species are common saprophytic fungi that naturally subsist on decaying plant materials, and occasionally may cause diseases in human beings and domestic animals. They can be a potential opportunistic pathogen in immunocompromized hosts or those with significant underlying disease. However, rarely they are also pathogen in otherwise healthy hosts.

Objectives: We used dual energy x-ray absorptiometry (DEXA) and periapical radiography to assess bone density differences after conventional and bone-condensing dental implant techniques.
Study Design: Single-tooth dental implants were placed by both conventional and bone-condensing techniques in 14 patients with bilateral missing teeth. Dual energy x-ray absorptiometry was used to calculate bone mineral density (BMD) and bone mineral content (BMC) before and 6 and 12 months after implant placement.
