  1. The role of increased gastrointestinal alcohol production in patients with the metabolic syndrome: Implications for the pathogenesis of non-alcoholic fatty liver disease

    The role of increased gastrointestinal alcohol production in patients with the metabolic syndrome: Implications for the pathogenesis of non-alcoholic fatty liver disease

    Aim. Explore the possibility that increased gastrointestinal alcohol production may play a role in the pathogenesis of non-alcoholic fatty liver disease in patients with the metabolic syndrome.
  2. Some notes on quasi-Lindelöf spaces

    Some notes on quasi-Lindelöf spaces

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this note we address a problem that was suggested by Petra Staynova in [6] regarding quasi-Lindelöf spaces, and continue to study topological properties of quasi-Lindelöf spaces. In particular, we construct an example of a Tychonoff weakly Lindelöf space which...
  3. On star-C-Menger spaces

    On star-C-Menger spaces

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    A space X is star-C-Menger if for each sequence (Un : n ∈ ℕ) of open covers of X there exists a sequence (Kn : n ∈ ℕ) of countably compact subsets of X such that {St(Kn, Un) : n...
  4. Remarks on almost Rothberger spaces and weakly Rothberger spaces

    Remarks on almost Rothberger spaces and weakly Rothberger spaces

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    A space X is almost Rothberger (weakly Rothberger) if for each sequence (un : n ∊ ℕ) of open covers of X there exists a sequence (Un : n ∊ ℕ) such that for every n ∊ ℕ, U ∊...
  5. Remarks on star-C-Menger spaces

    Remarks on star-C-Menger spaces

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper, we show that assuming ω1 < , there exists a Tychonoff star-C-Menger space having a regular-closed Gδ-subspace which is not star-C-Menger which gives a partial answer to a question of Song and Yin [12], and continue to...
  6. A note on monotonically star Lindelöf spaces

    A note on monotonically star Lindelöf spaces

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    A space X is monotonically star Lindelöf if one assign to for each open cover a subspace , called a kernel, such that s() is a Lindelöf subset of X, and , and if refines then , where . In...
