Frequency of Midfacial Traumatic Injuries - A report from the Maxillofacial Reconstructive and Plastic Surgery Department of Kyrgyz Republic Health Service Ministry's National Hospital, Bishkek from 2013-17 - A Retrospective Study.

Introduction: The aim of the study was to conduct a retrospective analysis of the fractures of the mid-face zone from 2013 to 2017 years in the above hospital and to determine the nature of the injuries and the main methods of diagnosis and treatment.

Materials And Methods: This was a retrospective analysis of 4966 patients who underwent treatment at the hospital from 2013 to 2017. Data about etiology, site of injury, time of admission to the clinic, number and type of associated injuries, type and length of treatment, and complications were analyzed.

Luteolin-7-methylether from Leonurus japonicus inhibits estrogen biosynthesis in human ovarian granulosa cells by suppression of aromatase (CYP19).

Leonurus japonicus (motherwort) has been widely used to treat gynecological disorders, in which estrogen is often dysregulated, for a long time in China and other Asian countries. However, the chemical constituents and mechanisms underlying the activity of this medicinal plant are not fully understood. Seventeen of forty-six tested natural products from L.

Externally Controlled Magnetism and Band Gap in Twisted Bilayer Graphene.

We theoretically study the effects of electron-electron interaction in twisted bilayer graphene in a transverse dc electric field. When the twist angle is not very small, the electronic spectrum of the bilayer consists of four Dirac cones inherited from each graphene layer. An applied bias voltage leads to the appearance of two holelike and two electronlike Fermi surface sheets with perfect nesting among electron and hole components.

Spin-Valley Half-Metal as a Prospective Material for Spin Valleytronics.

Half-metallicity (full spin polarization of the Fermi surface) usually occurs in strongly correlated electron systems. We demonstrate that doping a spin-density wave insulator in the weak-coupling regime may also stabilize half-metallic states. In the absence of doping, the spin-density wave is formed by four nested bands [i.

Instabilities of the AA-stacked graphene bilayer.

Tight-binding calculations predict that the AA-stacked bilayer graphene has one electron and one hole conducting band, and that the Fermi surfaces of these bands coincide. We demonstrate that as a result of this degeneracy, the bilayer becomes unstable with respect to a set of spontaneous symmetry violations. Which of the symmetries is broken depends on the microscopic details of the system.
