Recent interdisciplinary advances in materials, mechanics, and microsystem designs for biocompatible electronics, soft microfluidics, and electrochemical biosensors establish the foundations for emerging classes of thin, skin-interfaced platforms capable of capturing, storing, and performing quantitative, spatiotemporal measurements of sweat chemistry,...

RISM: Single-Modal Image Registration via Rank-Induced Similarity Measure.

IEEE transactions on image processing : a publication of the IEEE Signal Processing Society

Ghaffari A, Fatemizadeh E.
PMID: 26390463
IEEE Trans Image Process. 2015 Dec;24(12):5567-80. doi: 10.1109/TIP.2015.2479462. Epub 2015 Sep 16.

Similarity measure is an important block in image registration. Most traditional intensity-based similarity measures (e.g., sum-of-squared-difference, correlation coefficient, and mutual information) assume a stationary image and pixel-by-pixel independence. These similarity measures ignore the correlation between pixel intensities; hence, perfect...

Protective effects of melatonin on testis histology following acute torsion-detorsion in rats.

International journal of reproductive biomedicine

Mirhoseini M, Talebpour Amiri F, Karimpour Malekshah AA, Rezanejad Gatabi Z, Ghaffari E.
PMID: 28580446
Int J Reprod Biomed. 2017 Mar;15(3):141-146.

BACKGROUND: Testicular damage due to spermatic cord torsion may lead to infertility. It is probably because of changes in oxidative stress factors such as malondialdehyde.OBJECTIVE: To investigate the protective effect of melatonin (MLT), as an antioxidant, on testicular damage...

PMID: 29043284
Int J Community Based Nurs Midwifery. 2017 Oct;5(4):386-396.

BACKGROUND: Community-based nursing focuses on providing health services to families and communities in the second and third levels of prevention and this can improve the individuals, families and communities' quality of life, and reduce the healthcare costs. The aim...

Sustained release Curcumin loaded Solid Lipid Nanoparticles.

Advanced pharmaceutical bulletin

Jourghanian P, Ghaffari S, Ardjmand M, Haghighat S, Mohammadnejad M.
PMID: 27123413
Adv Pharm Bull. 2016 Mar;6(1):17-21. doi: 10.15171/apb.2016.004. Epub 2016 Mar 17.

PURPOSE: curcumin is poorly water soluble drug with low bioavailability. Use of lipid systems in lipophilic substances increases solubility and bioavailability of poorly soluble drugs. The aim of this study was to prepare curcumin loaded Solid Lipid Nanoparticles (SLNs)...

Effect of Silver Nano-particles on Tensile Strength of Acrylic Resins.

Journal of dental research, dental clinics, dental prospects

Ghaffari T, Hamedi-Rad F.
