The present study investigates the potential benefits of the Mexican medicinal plant Lopezia racemosa (Onagraceae). Extracts and fractions from aerial parts of this plant were assessed to determine their antibacterial, antifungal, antiparasitic, anti-inflammatory and cytotoxic activities in vitro. Aerial parts of the plant were extracted with various solvents and fractionated accordingly. Extracts
Ethnopharmacological relevance: To study the potential benefit of the traditional Mexican medicinal plant Galium mexicanum Kunth (Rubiaceae). Hexane, chloroform, and methanol extracts as well as various fractions from these extracts were tested to determine antibacterial, antifungal, antiparasitic or anti-inflammatory activities in vitro. Materials and methods: Aerial parts of the plant were extra
Flerovium (Fl, element 114) is the heaviest element chemically studied so far. To date, its interaction with gold was investigated in two gas-solid chromatography experiments, which reported two different types of interaction, however, each based on the level of a few registered atoms only. Whereas noble-gas-like properties were suggested from the first experiment, the second one pointed at a vola
Here we report large-amplitude transit timing variations (TTVs) for AU Microcopii b and c as detected in combined TESS (2018, 2020) and CHEOPS (2020, 2021) transit observations. AU Mic is a young planetary system with a debris disk and two transiting warm Neptunes. A TTV on the order of several minutes was previously reported for AU Mic b, which was suggested to be an outcome of mutual perturbatio
We study the structure of the backward shift invariant and nearly invariant subspaces in weighted Fock-type spaces ℱWp, whose weight is not necessarily radial. We show that in the spaces ℱWp, which contain the polynomials as a dense subspace (in particular, in the radial case), all nontrivial backward shift invariant subspaces are of the form ℘n, that is, finite-dimensional subspaces consisting of
In this book, it is explained that despite a current drop in the number of deaths, terrorism should still be considered a serious and widespread problem. However, the responses to this phenomenon are often more problematic from a long-term perspective. With the human rights framework under serious pressure, this edited volume offers a timely, important and critical in-depth analysis of human digni
Neutrophils contain an assembly of granules destined for regulated secretion, each granule type with distinct constituents formed before terminal differentiation. The earliest granules are designated azurophil (primary), followed in time by specific (secondary), and gelatinase granules as well as secretory vesicles. Transcription factors regulate the genes for the granule proteins to ensure that e
Med utgångspunkt i unikt arkivmaterial undersöker denna avhandling skillnader i hur västliga demokratier styrt radio och television. Genom en jämförande studie av fyra länder följer den de intressekonflikter som präglat etermediepolitiken — från de tidigaste radioregleringarna till kabel- och satellit-tv:s genomslag under slutet av nittonhundratalet.Snarare än att tolka politiska konflikter kring Using original archival evidence, this doctoral dissertation describes and explains differences in how Western democracies have governed radio and television, tracing interest group struggles over broadcasting in four countries from early radio policy to the rise of cable and satellite television in the late twentieth century.Rather than framing political conflicts over radio and television as a b
Cerebral accumulation of alpha-synuclein (αSyn) aggregates is the hallmark event in a group of neurodegenerative diseases—collectively called synucleinopathies—which include Parkinson’s disease, dementia with Lewy bodies and multiple system atrophy. Currently, these are diagnosed by their clinical symptoms and definitively confirmed postmortem by the presence of αSyn deposits in the brain. Here, w
The orientation of four different species of nocturnal passerine migrants was investigated in spring and autumn by orientation‐cage experiments at dusk, night, and dawn under natural clear skies. Our objective was to examine the orientation behaviour at different periods of a nocturnal migration flight, and to relate the orientation to visual orientation cues (the position of the sun). In robins,
In the present study trypsin mixed with various carbohydrates, i.e. lactose, sucrose, mannitol, α-cyclodextrin and dextrin, was spray-dried in order to investigate the effects of spray-drying on this enzyme, with particular emphasis on the effects of interactions between trypsin and the surface formed during spray-drying. The protein was strongly over-represented at the surface of the powder parti
The evolution of multicellularity is one of the major evolutionary transitions that has shaped the diversity of life on Earth. Multicellular organisms have arisen numerous times across the tree of life, but explaining why some lineages are multicellular while others are unicellular remains puzzling. In my thesis, we tested how the ecological variables may differentially favour multicellular and un
BACKGROUND: Tobacco smoking strongly increases risk of esophageal squamous cell carcinoma and moderately increases risk of esophageal adenocarcinoma. How smoking cessation influences esophageal cancer risk across histological subtypes, time latencies, and geographic regions is not clear.METHODS: Studies were systematically searched on Medline, Embase, Web of Science, Cochrane Library, and Clinical
We deal with a control problem for a complex social network in which each agent has an action and an opinion, evolving according to a coevolutionary model. In particular, we consider a scenario in which a committed minority - a set of stubborn nodes - aims to steer a population, initially at a consensus, to a different consensus state. Our study focuses on determining the conditions under which su
The paper explores the role and meaning of maṣlaḥa (social utility) and its possible appropriation in the field of Islamic legal and economic thought, as laid down by various medieval and contemporary Muslim scholars. Questions that are pertinent to the research are the following: how has maṣlaḥa been incorporated in legal reasoning and what kind of meaning does it convey; what type of economic (a
