Interaction between amphiphilic peptides and phospholipid membranes

This brief review aims at providing some illustrative examples on the interaction between amphiphilic peptides and phospholipid membranes an area of significant current interest Focusing on antimicrobial peptides factors affecting peptide-membrane interactions are addressed including effects of peptide length charge hydrophobicity secondary structure and topology Effects of membrane composition ar

Electrocardiographic predictors of clinical outcome in ST-elevation myocardial infarction

Malignant ventricular arrhythmias, particularly ventricular fibrillation (VF), remain an important contributor to mortality in ST-elevation myocardial infarction (STEMI). The size of myocardial injury is one more important factor influencing the prognosis of STEMI patients. The search for new non-invasive markers, which can be relatively simply calculated using conventional ECG recording and can p

The "shoulder" and the "ridge" in PHENIX

Comparison of two-particle correlations in heavy-ion collisions with measurements in proton collisions shows strong modification of the correlation shape and particle yields. Two new structures are created; both extended in Δη, one centered at Δ = 0 ('ridge') and the other occurring at Δ π ± 1.1 ('shoulder'). In these proceedings, we describe the measurements of these structures that show consiste

Nonisothermal moisture transport in hygroscopic building materials: modeling for the determination of moisture transport coefficients

A mathematical model for calculating the nonisothermal moisture transfer in building materials is presented in the article. The coupled heat and moisture transfer problem was modeled. Vapor content and temperature were chosen as principal driving potentials. The coupled equations were solved by an analytical method, which consists of applying the Laplace transform technique and the Transfer Functi

Hematopoiesis: Functional Insights by Cell Fate Conversion

Popular Abstract in Swedish Varje dag produceras miljardtals nya blodceller, vilka exempelvis har som uppgift att transportera runt syre och försvara kroppen mot olika invaderande bakterier och virus. Dessa olika blodkomponenter har sitt ursprung i sällsynta blodbildande stamceller som återfinns i benmärgen. Dessa är så kallade vävnadsspecifika stamceller och har både förmågan att återbilda sig sjBlood cell formation, or hematopoiesis, is maintained by rare hematopoietic stem cells (HSCs) residing in the bone marrow (BM). HSCs may self-renew (the process whereby HSCs replicate to produce new HSCs) to preserve their own numbers, as well as initiate a highly coordinated hierarchical differentiation process that results in the production of mature effector blood cells. Aging is characterized

Medier och minnen

The rapid technological developments of the new millennium have presented exciting challenges to the well-established field of cultural memory studies. Today, it behoves us analyse the ways in which digital systems make it possible to store, copy, and decentralize memories, making them increasingly accessible on the Internet. The digital media offer gateways to the past that are more comprehensive

Parasitism of Palmistichus elaeisis Delvare & LaSalle, 1993 on pupae of Methona themisto (Hubner, [1818]) reared on two hosts (Lepidoptera: Nymphalidae; Hymenoptera: Eulophidae)

Previous studies showed that larvae of Methona themisto (Hubner, [ 1818]) (Lepidoptera: Nymphalidae) display a showy yellow color to avoid predation. In addition, these larvae absorb secondary compounds when feeding on Brunfelsia uniflora (Pohl) D. Don (Solanaceae) plants, although this does not prevent pupal parasitism by Palmistichus elaeisis Delvare & LaSalle, 1993 (Hymenoptera: Eulophidae)

3d photoionization and subsequent decay of atomic gallium

We present an experimental and theoretical study of 3d photoionization and subsequent Auger decay of atomic gallium. The synchrotron radiation-induced electron spectra have been compared and analysed using multiconfiguration Dirac-Fock calculations. It has been shown that the theoretically predicted photoelectron spectrum is in rather good agreement with the experiment allowing us to identify the

Too early to infer a global NPP decline since 2000

The global terrestrial carbon cycle plays a pivotal role in regulating the atmospheric composition of greenhouse gases. It has recently been suggested that the upward trend in net primary production (NPP) seen during the 1980's and 90's has been replaced by a negative trend since 2000 induced by severe droughts mainly on the southern hemisphere. Here we compare results from an individual-based glo

Power in Telephone-advice Nursing

Power is a central aspect of nursing, especially in telephone-advice nursing, where nurses assess callers' medical problems and decide what measures that need to be taken. This article presents a framework for understanding how power operates in social interaction between nurses and callers in telephone-advice nursing in primary care in Sweden. Power is analysed as the result of nurses and callers

Brain Activity in Predictive Sensorimotor Control for Landings: an EEG Pilot Study

Landing from a jump is related to predictive sensorimotor control. Frontal, central and parietal brain areas are known to play a role in this process based on online sensory feedback. This can be measured by EEG. However, there is only limited knowledge about brain activity during predictive preparation for drop landings (DL). The purpose is to demonstrate changes in brain activity in preparation

Non-binary and linear precoded faster-than-Nyquist signaling

Faster than Nyquist (FTN) signaling is an important method of narrowband coding. The concept is extended here to non binary signal constellations; these are much more bandwidth efficient than binary ones. A powerful method of finding the minimum distance for binary and non binary FTN is presented. Precoding FTN transmissions with short linear filters proves to be an effective way to gain distance.

Dynamical screening in La2CuO4

We show that the dynamical screening of the Coulomb interaction among Cu-d electrons in high-Tc cuprates is strong and that a proper treatment of this effect is essential for a consistent description of the electronic structure. In particular, we find that ab initio calculations for undoped La2CuO4 in the paramagnetic phase yield an insulator only if the frequency dependence of the Coulomb interac
