Spin Waves and Three Dimensionality in the High-Pressure Antiferromagnetic Phase of SrCu_{2}(BO_{3})_{2}.

Quantum magnetic materials can provide explicit realizations of paradigm models in quantum many-body physics. In this context, SrCu_{2}(BO_{3})_{2} is a faithful realization of the Shastry-Sutherland model for ideally frustrated spin dimers, even displaying several of its quantum magnetic phases as a function of pressure. We perform inelastic neutron scattering measurements on SrCu_{2}(BO_{3})_{2} at 5.

Field-induced bound-state condensation and spin-nematic phase in SrCu(BO) revealed by neutron scattering up to 25.9 T.

In quantum magnetic materials, ordered phases induced by an applied magnetic field can be described as the Bose-Einstein condensation (BEC) of magnon excitations. In the strongly frustrated system SrCu(BO), no clear magnon BEC could be observed, pointing to an alternative mechanism, but the high fields required to probe this physics have remained a barrier to detailed investigation. Here we exploit the first purpose-built high-field neutron scattering facility to measure the spin excitations of SrCu(BO) up to 25.

Role of perioperative parathormone hormone level assay after total thyroidectomy as a predictor of transient and permanent hypocalcemia: Prospective study.

Background: The researchers are trying to evaluate the measurement of: Intact parathyroid hormone (iPTH) and serum total calcium (sCa) levels for predicting hypocalcemia after total thyroidectomy (TT).

Methods: The sample of this single center prospective study consists of (100) patients, where (77) females and (23) males with an age range between (28) and (65) (the mean level is, 48.17 ± 6.

Comparative Study Between Silver Nanoparticles Dressing (SilvrSTAT Gel) and Conventional Dressing in Diabetic Foot Ulcer Healing: A Prospective Randomized Study.

Background: We are trying to evaluate silver nanoparticles' effectiveness (SilvrSTAT Gel) in accelerating healing rate of nonischemic diabetic foot ulcers (DFUs).

Methods: This prospective, double-blind, randomized, controlled study includes 80 patients with nonischemic DFUs classified into 2 groups. Group A was subjected to SilvrSTAT Gel dressing, and group B was subjected to conventional dressing (wet-to-moist dressing with or without povidone-iodine).

Evaluation of ultrasonic axillary dissection in preservation of intercostobrachial nerve and lymphatic sealing in breast cancer patients: Randomized controlled trial.

Background: Electrocautery has been shown to be associated with excessive serous drainage which may lead to many complications in patients with breast cancer needing dissection of the axillary lymph nodes. The Harmonic Focus could outperform electrocautery in dissection of axillary lymph nodes, resulting in shortening of the operative times and minimize postoperative complications This study aims to compare the mean axillary drain production and the axillary numbness frequency in axillary lymph node dissection (ANLD) during Modified Radical Mastectomy (MRM) and breast conservative surgery (BCS) between the use of harmonics scalpel and electrocautery.

Methods: This study includes 40 patients presented with early breast cancer (T1 and T2) underwent BCS or MRM in general surgery department, Faculty of Medicine, Benha University Hospital during the period from January 2017 to September 2019.

Incidence of Silent Deep Venous Thrombosis after Laparoscopic Bariatric Surgery in Patients Who Received Combined Mechanical and Chemical Thromboprophylaxis Compared to Patients Who Received Mechanical Thromboprophylaxis Only.

This prospective randomized study compares the incidence of silent deep venous thrombosis (DVT) among 2 groups of patients who underwent laparoscopic bariatric surgery. The first group received mechanical thromboprophylaxis only, while the second group received a combination of mechanical and chemical thromboprophylaxis. .
