INTRODUCTION Peripheral nerve blocks have been used in primary headache treatment since a long time. In this study, we aimed to examine the efficiency of greater occipital nerve (GON) block in migraine prophylaxis. METHODS Data from migraine without aura patients who had GON block were collected and divided into two groups: Group PGON (n=25), which included patients who were under medical pro...

This paper investigates the energy UMD of polygonal unknots. It provides equations for finding the energy for any planar regular n-gon and for any m-gon, where the vertices lie on the vertices of a regular m 2 -gon and on the midpoints of each edge. In addition, we show that a regular 4-gon minimizes the energy for any quadrilateral. Finally, this paper includes a proof showing that if we have ...

A disintegrin-like and metalloprotease with thrombospondin type I motif (ADAMTS9) is a member of the secreted metalloprotease family that is believed to digest extracellular matrix (ECM) proteins outside of cells. Its Caenorhabditis elegans orthologue, GON-1, is involved in ECM degradation and is required for gonad morphogenesis. ADAMTS9 and GON-1 have similar domain structures, and both have a...

Genomic Object Net (GON) is a biosimlation tool that allows us to model various kinds of biopathways including gene regulatory networks, metabolic pathways, and signal transduction pathways in a biologically intuitive way [4]. In GON, biopathway is modeled as an extension of hybrid Petri net called hybrid functional Petri net (HFPN) for which XML documentation is defined. As a graphical editor ...

A bicycle (n, k)-gon is an equilateral n-gon whose k-diagonals are equal. S. Tabachnikov proved that a regular n-gon is first-order flexible as a bicycle (n, k)-gon if and only if there is an integer 2 ≤ r ≤ n − 2 such that tan(π/n) tan(krπ/n) = tan(kπ/n) tan(rπ/n). In the present paper, we solve this trigonometric diophantine equation. In particular, we describe the family of first order flexi...

Most developing organs are surrounded by an extracellular matrix (ECM), which must be remodeled to accommodate growth and morphogenesis. In C. elegans, the GON-1 ADAMTS metalloprotease regulates both elongation and shape of the developing gonad . Here, we report that either human ADAMTS-4 or ADAMTS-9 can substitute for GON-1 in transgenic worms, suggesting functional conservation between human ...

An arrangement of lines is constructed by choosing n diagonals of the regular 2/i-gon. This arrangement is proved to form at least n(n 3)/3 triangular cells.

PURPOSE To compare the patterns of retinal ganglion cell (RGC) damage in the macular and peripapillary areas in compressive optic neuropathy (CON) and glaucomatous optic neuropathy (GON) using spectral-domain optical coherence tomography (SD-OCT), and to determine the usefulness of SD-OCT macular and peripapillary analysis in discriminating between CON and GON. METHODS Sixty-three eyes with C...

BACKGROUND Spermatogenesis is a complex process involving cell development, differentiation and apoptosis. This process is governed by a series of genes whose expressions are highly regulated. Male infertility can be attributed to multiple genetic defects or alterations that are related to spermatogenesis. The discovery, cloning and further functional study of genes related to spermatogenesis i...
