one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...
Adhesion molecules are integral membrane proteins that have cytoplasmic, transmembrane and extracellular domains. Dozens of different adhesion molecules have been identified, but, adhesion molecules are conventionally divided into four main groups, each of which has a different function:
Cell membranes interact via anchored receptor and ligand molecules. Central questions on cell adhesion concern the binding affinity of these membrane-anchored molecules, the mechanisms leading to the receptorligand domains observed during adhesion, and the role of cytoskeletal and other active processes. In this review, these questions are addressed from a theoretical perspective. We focus on m...
abstract the present study was an attempt to investigate the effect of critical thinking on writing ability of 60 iranian intermediate efl learners studying at chenar language institute in khuzestan, iran. to this end, the participants of the study were selected based on their performance in an pet test, a cornell critical thinking test form x and a pre-test of writing. the participants un...
abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
Breast cancer is highly prevalent worldwide. Treatment of this disease is a major global public health problem; therefore, numerous studies have explored new molecular profile helping for breast cancer therapy. Different risk factors are attributed to breast cancer; however, chronic inflammation and immune regulation are highly essential. Various molecules impact this context, including toll-li...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
Carcinoembryonic antigen (CEA) is an oncofetal protein whose regulation is poorly understood, although CEA is commonly expressed on many carcinoma cell types and enhances experimental metastases. The abundance of membrane-associated CEA was increased 3-fold when HDG colon carcinoma cells were prevented from polarizing by culture for 3 days in low calcium medium. Polarization is an early event i...
Background and Objective: Adhesion molecules play an important role in the pathogenesis of atherosclerosis. The aim of this study was to assess the effect of combined exercise on vascular adhesion molecules and lipid profile in obese and overweight women. Materials and Methods: Eighteen women participated in this study (age: 39.33±7.7 years; weight: 76.57±5.19 kg). The subjec...
