Ameliorating Role Exerted by Al-Hijamah in Autoimmune Diseases: Effect on Serum Autoantibodies and Inflammatory Mediators.

International journal of health sciences

Baghdadi H, Abdel-Aziz N, Ahmed NS, Mahmoud HS, Barghash A, Nasrat A, Nabo MM, El Sayed SM.
PMID: 26309442
Int J Health Sci (Qassim). 2015 Apr;9(2):207-32.

Autoimmune diseases have common properties characterized by abnormal blood chemistry with high serum autoimmune antibodies, and inflammatory mediators. Those causative pathological substances (CPS) cannot be excreted by physiological mechanisms. Current treatments for autoimmune diseases involve steroids, cytotoxic drugs, plasmapheresis...

Electronic and vibrational dynamics of hollow au nanocages embedded in cu2 o shells.

Photochemistry and photobiology

Szymanski P, Mahmoud MA, O'Neil D, Garlyyev B, El-Sayed MA.
PMID: 25682692
Photochem Photobiol. 2015 May-Jun;91(3):599-606. doi: 10.1111/php.12432. Epub 2015 Mar 10.

We have synthesized hollow Au nanocages embedded within thick porous shells of cuprous oxide (Cu2 O). The shell causes a significant redshift of the localized surface plasmon resonance of Au into the near-IR. Electron-phonon coupling in the Au nanocage...

Optical signatures of intrinsic electron localization in amorphous SiO2.

Journal of physics. Condensed matter : an Institute of Physics journal

El-Sayed AM, Tanimura K, Shluger AL.
PMID: 26053871
J Phys Condens Matter. 2015 Jul 08;27(26):265501. doi: 10.1088/0953-8984/27/26/265501. Epub 2015 Jun 08.

We measure and analyse the optical absorption spectra of three silica glass samples irradiated with 1 MeV electrons at 80 K, where self-trapped holes are stable, and use ab initio calculations to demonstrate that these spectra contain a signature...

In Vivo Interrelationship between Insulin Resistance and Interferon Gamma Production: Protective and Therapeutic Effect of Berberine.

Evidence-based complementary and alternative medicine : eCAM

Mahmoud MA, Ghareeb DA, Sahyoun HA, Elshehawy AA, Elsayed MM.

Evid Based Complement Alternat Med. 2016;2016:2039897. doi: 10.1155/2016/2039897. Epub 2016 Aug 24.

This research was conducted to investigate if there is a relation between insulin resistance incidence and inhibition of interferon gamma production or not. Firstly, insulin resistance was induced by high fat diet (HFD) intake for 6 weeks. Secondly, berberine...

A new antibacterial lupane ester from the seeds of Acokanthera oppositifolia Lam.

PMID: 27046822
Nat Prod Res. 2016 Dec;30(24):2813-2818. doi: 10.1080/14786419.2016.1166494. Epub 2016 Apr 04.

As a part of ongoing investigation of Acokanthera oppositifolia (Lam.) Codd., four compounds were isolated from its seeds, a new compound; lup-20(29)-en-3β-O-(3'-β-hydroxy) palmitate (1), three known compounds; a triterpene; lupeol (2), a cardiac glycoside; acovenoside A (3) and a...

Controlling the Catalytic Efficiency on the Surface of Hollow Gold Nanoparticles by Introducing an Inner Thin Layer of Platinum or Palladium.

The journal of physical chemistry letters

Mahmoud MA, Garlyyev B, El-Sayed MA.
PMID: 26278937
J Phys Chem Lett. 2014 Dec 04;5(23):4088-94. doi: 10.1021/jz502071v. Epub 2014 Nov 14.

The efficiency of heterogeneous catalysis of electron-transfer reactions on the surface of gold nanoshells was changed by adding an inner platinum or palladium nanoshell in the double-shell nanocatalysts. The reduction of 4-nitrothiophenol (4NTP) by borohydride was studied as a...

Metronomic chemotherapy and radiotherapy as salvage treatment in refractory or relapsed pediatric solid tumours.

Current oncology (Toronto, Ont.)

Ali AM, El-Sayed MI.
PMID: 27330362

BACKGROUND: Metronomic chemotherapy (mctx) combined with radiation therapy (rt) is an emerging anticancer strategy. The aim of the present study was to assess the efficacy of mctx combined with rt as salvage treatment in children with refractory or relapsed...

Shape- and symmetry-dependent mechanical properties of metallic gold and silver on the nanoscale.

Nano letters
