Ultrastructure and functional organization of mouthpart sensory setae of the spiny lobster Panulirus argus: New features of putative mechanoreceptors

In comparison with other decapods, the Caribbean spiny lobster Panulirus argus has little diversity in the external morphology of the setae on the mouth apparatus. In mouthpart areas that frequently touch food items only two types of setae can be distinguished: simple setae and cuspidate setae. Simple setae are by far more numerous. The ultrastructural data presented here show that both types of s

C1-TEN is a negative regulator of the Akt/PKB signal transduction pathway and inhibits cell survival, proliferation, and migration

We have previously identified C1 domain-containing phosphatase and TENsin homologue (C1-TEN) as being an intracellular binding partner for Axl receptor tyrosine kinase (RTK). C1-TEN is a tensin-related protein that houses an N-terminal region with predicted structural similarity to PTEN. Here, we report our observations on the effects of ectopic expression of C1-TEN in HEK293 cells, which resulted

In vitro activity of synthetic antimicrobial peptides against Candida

Yeast-like fungi are the most common cause of fungal infections in humans. Actually, in the age of opportunistic infections and increasing resistance, development of modern antifungal agents becomes a very important challenge. This paper describes synthesis and antimicrobial assay of four naturally occurring peptide antibiotics (aurein 1.2, citropin 1.1, temporin A, uperin 3.6) and three chemicall

Cluster headache - Aetiology, diagnosis and management

Cluster headache is characterised by repeated attacks of strictly unilateral pain in the orbital region associated with local autonomic symptoms or signs. The attacks are brief but of a very severe, almost excruciating intensity. For unknown reasons males are affected more often than females. Recent studies suggest that an autosomal dominant gene has a role in some families with cluster headache.

Computational Methods for Hybrid Systems

This thesis considers two different computational approaches for the analysis and synthesis of nonlinear systems. Each of these approaches is presented in a conference paper that describes parts of the theory and algorithms. Matlab commands implementing the algorithms have been developed and the manuals for these are included herein as well.

Ortopedtekniska insatser : ett försök till analys av effekter på välfärd och livskvalitet : några fallstudier

Med hjälp av elva fallstudier undersöktes hur livskvaliteten hos funktionshindrade påverkas av tillgången till ortopedtekniska (OT) hjälpmedel och professionella insatser. Resultatet tyder på att det finns stora skillnader i insatser för samma funktionshinder och därmed kostnader mellan olika personer som får OT-hjälpmedel. Den som lever ett mer aktivt liv och t ex sportar får i regel mer avancera

Study of vacancy decays in the L-shell photoionization of barium in the excitation energy range of 5.6-30 keV: from L-2 edge to energy high above the thresholds of double L-vacancy production

Photoinduced Ba L x-rays were measured, in the excitation energy range of 5.6-30 keV, by using high-brilliance undulator radiation. The obtained intensity ratios, the excitation-energy independent L beta(4)/L beta(3), L eta/L beta(1), L iota/L alpha(1,2), L beta(6)/ L alpha(1,2) and L beta(2,15)/L alpha(1,2) as well as the excitation- energy dependent L beta(1)/L alpha(1,2), L beta(3)/L alpha(1,2)

First Observation of the Nuclei 87Tc and 88Tc

The gamma-decay of excited states in the neutron deficient isotopes Tc-87 and Tc-88 has been observed for the first time. The fusion-evaporation reactions Ni-58(S-32, p2n)Tc-87 and Ni-58(S-32, pn)Tc-88 at 110 MeV, Ca-40(Cr-50, p2n)Tc-87 and Ca-40(Cr-50, pn)Tc-88 at 170 MeV and Ni-58(Ar-36, alpha-pn)Tc-88 at 145 MeV beam energy were used. Unambiguous identification of these nuclei which are populat

Stadsbarndom : Om barns vardag i en modern förort

Popular Abstract in Swedish Barns villkor i stadsmiljö är ett viktigt tema för förståelsen av den moderna barndomen. Barn har emellertid sällan tillfrågats om sin syn på stadens miljövillkor. Avhandlingens syfte är sammanfattningsvis: * Att beskriva de sakkunnigas försök att skapa goda uppväxtvillkor för barn i stadsmiljö, utifrån det jag sammanfattande benämner "de för barnen tänkta perspektivenChildren's conditions in urban environments are an important theme for understanding modern childhood, yet children have rarely been asked about their views of urban childhood conditions. The aim of the dissertation is: To describe the experts' attempts to create good conditions for growing up in an urban environment. This is summed up as "perspectives thought out for the children". To investiga

Thermionic current reversal

We have analysed the thermionic current over a potential barrier between a hot and a cold metallic wire, in the absence of an externally applied electric field. Because of the quantum nature of the transmission probability and the temperature behaviour of the Fermi distribution function, under proper conditions the thermionic electric current reverses its direction. However, the heat current remai

Treatment with laquinimod reduces development of active MRI lesions in relapsing MS

Background: Laquinimod is a novel immunomodulatory substance developed as an orally available disease modifying treatment in multiple sclerosis ( MS). The purpose of this study was to evaluate safety, tolerability, and efficacy on MRI lesions of two different doses of laquinimod compared with placebo in patients with relapsing MS. Methods: In this multicenter, double-blind, randomized trial, patie

Routine perinatal postmortem radiography in a peripheral pathology laboratory

Routine postmortem radiography was done in 234 consecutive perinatal autopsies. Using ossification centre appearance and length of femoral shafts as variable it was a very useful and dependable method for estimating gestational age and intrauterine growth. In this way important conclusions can be drawn as to the reason for intrauterine growth deviations. Also many, sometimes diagnostic, abnormalit
