Phytoglobins (Pgb) (plant hemoglobins) are heme-containing proteins and less well known in comparison to the mammalian counterparts hemoglobin (Hb) andmyoglobin (Mb). They share the same secondary structure as other globin-related proteins, six to eight α-helices comprising the myoglobin-fold (Mb-fold) with one prosthetic heme moiety per subunit. Pgbs are divided into different classes, where the

In advanced Parkinson's disease, l-DOPA treatment causes the appearance of abnormal involuntary movements or l-DOPA-induced dyskinesia (LID). LID results in part from l-DOPA-induced activation of extracellular signal-regulated kinase (ERK) in the dopamine-denervated striatum. Activated ERK triggers nuclear responses, including phosphorylation of mitogen- and stress-activated protein kinase 1 (MSK1

Angiogenesis is a hallmark of cancer and is now a validated therapeutic target in the clinical setting. Despite the initial success, anti-angiogenic compounds impinging on the vascular endothelial growth factor (VEGF) pathway display limited survival benefits in patients and resistance often develops due to activation of alternative pathways. Thus, finding and validating new targets is highly warr

Problem-based learning (PBL) has proven to be highly effective for educating students in an active and self-motivated manner in various disciplines. Student projects carried out following PBL principles are very dynamic and carry a high level of uncertainty, both conditions under which agile project management approaches are assumed to be highly supportive. The paper describes an empirical case st

Recreational hunting evokes emotions and could be described as a contested space. The paper presents a study of recreational hunting in Sweden, focusing on accounts and narratives from ethnographic interviews with hunting tourism operators. It discusses how the notion of sustainability permeates and frames moral accounts of hunting practices, game meat, wildlife management, business ethics, animalRecreational hunting evokes emotions and could be described as a contested space.

The urban cemetery is a built green environment that is both a place of death, belonging to the bereaved and their rituals of care and remembrance, and a recreational space, where people rest, walk their dog, jog, reflect in silence, or just pass through. Urban cemeteries and urban parks share some features and uses in that respect, but they also have very different meanings and functions. The res

Several experimental evidences suggested that beta1 integrin-mediated adhesion of hematopoietic stem cells (HSC) is important for their function in the bone marrow (BM). Using induced deletion of the beta1 integrin gene restricted to the hematopoietic system, we show that beta1 integrin is not essential for HSC retention in the BM, hematopoiesis, and trafficking of lymphocytes. However, immunizati

Popular Abstract in Swedish Atomspektra har varit ett viktigt forskningsområde inom fysiken sedan mitten av 1800-talet. Då elektromagnetisk strålning, såsom synligt ljus, ultraviolett- och röntgenstrålning, är unik för varje grundämne ger ett observerat spektrum information om vilka slags atomer som emitterar strålningen. Exempelvis så visar spektra av ett vanligt lysrör att ljuset kommer från kviThe spectra of highly charged tungsten ions have been investigated using x-ray and extreme ultraviolet spectroscopy. These heavy ions are of interest in relativistic atomic structure theory, where high-precision wavelength measurements benchmark theoretical approaches, and in magnetic fusion research, where the ions may serve to diagnose high-temperature plasmas. The work details spectroscopic in
