Numerical study for multi-strain tuberculosis (TB) model of variable-order fractional derivatives.

Journal of advanced research

Sweilam NH, Al-Mekhlafi SM.
PMID: 26966568
J Adv Res. 2016 Mar;7(2):271-83. doi: 10.1016/j.jare.2015.06.004. Epub 2015 Jun 27.

In this paper, we presented a novel multi-strain TB model of variable-order fractional derivatives, which incorporates three strains: drug-sensitive, emerging multi-drug resistant (MDR) and extensively drug-resistant (XDR), as an extension for multi-strain TB model of nonlinear ordinary differential equations...

Measuring Surface Hydrophobicity as Compared to Measuring a Hydrophobic Effect on Adhesion Events.

Journal of food protection

Al-Makhlafi H, Lakamraju M, Podhipleux N, Singla B, MCGUlRE J.
PMID: 31137414
J Food Prot. 1995 Sep;58(9):1034-1037. doi: 10.4315/0362-028X-58.9.1034.

Simple contact-angle methods are commonly used to describe surface influences on phenomena including adsorption, adhesion, fouling, and cleaning, However, for the purpose of quantitatively relating surface hydrophobicity to such phenomena, contact-angle analysis may be insufficient. Here we show that...

Targeting focal ischemic and hemorrhagic stroke neuroprotection: Current prospects for local hypothermia.

Journal of neurochemistry

J Neurochem. 2022 Jan;160(1):128-144. doi: 10.1111/jnc.15508. Epub 2021 Sep 21.

Therapeutic hypothermia (TH) has applications dating back millennia. In modern history, however, TH saw its importation into medical practice where investigations have demonstrated that TH is efficacious in ischemic insults, notably cardiac arrest and hypoxic-ischemic encephalopathy. As well, studies...
