Abstract Red alga dulse contains xylan with β(1→3)/β(1→4) linkages. We previously prepared xylooligosaccharides (XOSs) from xylan; however, the product contained many d -xylose residues and fewer XOSs β(1→3) To improve efficiency of XOS production, we two recombinant endoxylanases Streptomyces thermogriseus (StXyl10 StXyl11). Comparing k cat / K m values for xylan, this value StXyl10 was approx...

Background Non-specific chronic low back pain (NSCLBP) is one of the most common musculoskeletal disorders globally, as approximately 10-40% individuals experience it [1] . Chronic characterized when persists more than 12 weeks, and non-specific causes are unknown origin [2] People with NSCLBP present weakness multifidus, transversus abdominis, internal oblique gluteus maximus muscles difficult...

The chemical composition of the essential oils of flower at the pre-flowering, full-flowering and post-flowering stage of A. annua was analyzed by GC and GC/MS and sixty-two components were identified. The main compounds in the pre-flowering oil were β-myrcene (37.71%), 1, 8-cineole (16.11%) and camphor (14.97%). The full-flowering oil contained predominantly caryophyllene (19.4%), germacrene D...

Background: Antibiotics with β-Lactam rings (β-Lactams), since they were discovered, have enhanced the typical treatment for bacterial infections. Though their resistance can quickly spread on a universal scale, is primarily caused by production of β-lactamases. Hence, there serious demand to design and create new anti-β-lactamases or inhibitors. Nowadays, use β-lactamase inhibitors β-lactams r...

We consider interlacing properties satisfied by the zeros of Jacobi polynomials in quasi-orthogonal sequences characterised by α > −1, −2 < β < −1. We give necessary and sufficient conditions under which a conjecture by Askey, that the zeros of Jacobi polynomials P (α,β) n and P (α,β+2) n are interlacing, holds when the parameters α and β are in the range α > −1 and −2 < β < −1. We prove that t...
