We consider Boolean circuits over {∨, ∧, ¬} with negations applied only to input variables. To measure the “amount of negation” in such circuits, we introduce the concept of their “negation width.” In particular, a circuit computing a monotone Boolean function f(x1, . . ., xn) has negation width w if no nonzero term produced (purely syntactically) by the circuit contains more than w distinct negat
Aims: Few studies have examined how improved metabolic control might influence vibration perception thresholds (VPTs). The aim of this study was to evaluate if improved HbA1c can influence vibration thresholds in adults with type 1 diabetes (T1DM). Methods: VPTs were investigated at six frequencies (4–125 Hz) using VibroSense Meter in the sole of the foot at two occasions in 159 T1DM patients, at
Previous open-label trials testing glial cell line-derived neurotrophic factor (GDNF) family ligands in Parkinson disease have shown promising clinical effects. However, in placebo-controlled trials, the treatments have failed. A new randomized placebo-controlled trial of intraputamenal delivery of GDNF designed to resolve this conundrum has again failed to do just that.
Accumulating data suggest that neutrophil extracellular traps (NETs) exert a key function in several diseases. Peptidylarginine deiminase 4 (PAD4) regulates NET formation via citrullination of histones. The aim of this study was to examine the role of miR-155 in controlling PAD4-dependent generation of NETs. Bone marrow neutrophils were stimulated with PMA and MIP-2. Pre-incubation of neutrophils
Genomgång av existerande dokumentation i Lunds universitetsarkiv rörande folkbildaren och riksdagsmannen Oscar Olssons studietid 1897-1902 med särskilt fokus på Hans Larssons undervisning under denna period.
Shotgun proteomics based on peptide fractionation by using liquid chromatography has become the common procedure for proteomic studies, although in the very beginning of the field, protein separation by using electrophoresis was the main tool. Nonetheless, during the last two decades, the electrophoretic techniques for peptide mixtures fractionation have evolved as a result of relevant technologic
Biografisk artikel om Bengt Bergius (1723-1784) med fokus på dennes "Tal om läckerheter" inför Kungl. Vetenskapsakademien 1780.
This chapter discusses the changes in protein phosphorylation following ischemia, with particular reference to the regulation of the initiation of protein synthesis. Transient cerebral ischemia seems to induce a post-ischemic imbalance between protein kinase and protein phosphatase activities, leading to a net dephosphorylation of proteins in the vulnerable neurons. This imbalance may lead to the
This chapter is a first attempt to capture the phenomenon of inter-firm credit between breweries and bars and restaurants in Sweden. I ask three interrelated questions: 1. Why do breweries in Sweden provide credit to bars and restaurants? 2. How is this credit designed? 3. What are the effects of this credit relationship? Question 2 is about the design of this credit and focuses on the aspects of
INTRODUCTION: Drugs directed toward the epidermal growth factor receptor (EGFR), such as erlotinib (Tarceva®) and gefitinib (Iressa®), are used for the treatment of patients with advanced non-small cell lung cancer (NSCLC), including patients with brain metastases. However, whether erlotinib actually enters into brain metastases has not been adequately elucidated. In this study, we investigated th
Situations of multilingualism and language contact in which language varieties are small in scale and relatively equal in social status are important phenomena affecting processes of language change throughout human history. Despite this, our knowledge about the outcomes of multilingualism and language contact in this kind of setting remains limited. The current thesis provides insight into the li
Most pathogens can infect a number of different host species, but host species often differ considerably in susceptibility to a given pathogen. In the case of zoonotic pathogens, natural hosts typically present little or no disease symptoms, while humans and other “spill-over” hosts often present severe symptoms. Differences in susceptibility do not only occur between natural and non-natural hosts
Ovid closed his 15-book epic of transformation with the metamorphosis of the poet into his work and his work into its own reception, summed up in the final word: uiuam (‘I shall live’). The prophecy has been self-fulfilling, in that the Metamorphoses has entertained readers and inspired artists in different media for two millennia since the poet’s death in AD 17. Loved for its vast repository of m
