Background: Flow-dependent concentration polarization of native LDL is important in the localization of atherogenesis. However, ox-LDL plays a more important role than n-LDL in atherogenesis by inducing cell proliferation and apoptosis. We hypothesized that concentration polarization of ox-LDL may adversely affect vascular beds due to its toxicity to endothelial cell (EC) lining.
Methods: Using a parallel-plate flow chamber technique, we studied water filtration rate and wall concentration of ox-LDLs EC monolayers cultured on permeable or non-permeable membranes. ECs cultured on permeable and non-permeable membranes were examined in terms of cell viability, ox-LDL uptake, LOX-1 expression and cell apoptosis (Cytochrome c and Bcl-2 expression). We observed that the wall concentration of ox-LDL was about 16% higher in the permeable group than in the permeable group (P<0.05). Cell proliferation (MTT assay) increased in response to low concentration of ox-LDL (1-5 μg/ml), and fell drastically in response to higher concentration; all these changes were more pronounced in the permeable group than in the non-permeable group. The uptake of ox-LDL and LOX-1 expression by ECs were also significantly higher in the permeable group than in the non-permeable group of cultured cells.
Conclusions: These observations suggest that concentration polarization of ox-LDL occurs in an artery that is permeable to water, and ox-LDL concentration polarization can enhance ox-LDL accumulation into the arterial wall and accelerate EC proliferation at low concentrations and apoptosis at high concentrations, possibly via LOX-1 expression.
Myocardial coronary bridging , encasement , and mid-LAD rigid straightening [3-5] appears to be epiphenomenon of takotsubo syndrome , rather than causing the disease. Typical takotsubo syndrome usually lasts only a few weeks, but chronic takotsubo cardiomyopathy is reported .
In a series of meanwhile 10 cases rigid straightening of the mid-portion of the left anterior descending coronary artery without lumen reduction mid-ventricular or basal ballooning was reported, or both basal and mid-ventricular ballooning in one case . In all these patients wrap-around (recurrent segment) phenomenon of the left anterior descending coronary artery was not present. The abnormalities of the left anterior descending coronary artery are due to myocardial bridging without lumen reduction of the LAD, only seen in computed tomography . When stress or in some cases happiness appears myocardial ballooning can appear, lasts 2-4 weeks and disappear with a recurrence rate of nearly 10% despite beta blocking agents .
Background: Left atrial volume (LAV) has been established as a sensitive marker of left ventricular (LV) diastolic function and as an independent predictor of mortality in patients with acute myocardial infarction (AMI). LA remodeling and its determinants in the setting of AMI have not been much studied.
Methods: We studied 53 patients with anterior AMI and a relatively preserved LV systolic function, who underwent complete reperfusion and received guidelines guided antiremodeling drug management. LA and LV remodeling were assessed using 2D echocardiography at baseline and 6 months. LAV indexed for BSA (LAVi) was used as the index of LA size and further LA remodeling.
Results: LAVi increased signifi cantly at 6 months compared to baseline [28.1 (23.0-34.5) vs 24.4 (19.5- 31.6) ml/m2, p=0.002] following LV end diastolic-volume index change [56.8 (47.6-63.9) vs 49.5 (42.0-58.4) ml/m2, p=0.0003]. Other standard LV diastolic function indices did not show any signifi cant change. Univariateanalysis showed a strong positive correlation of LAVi change with BNP levels at discharge, LV mass index and LV volumes indices change, throughout the follow up period. Multivariate regression analysis revealed that BNP plasma levels was the most important independent predictor of LA remodeling (b-coef.=0.630, p=0.001).
Conclusions: Despite current antiremodeling strategies in patients with AMI, LA remodeling is frequently asssociated with LV remodeling. Additionally LAVi change in the mid-term reflects better than standard echocardiographic indices LV diastolic filling impairment.

Thank you for your attitude and support. I am sincerely grateful to you and the entire staff of the magazine for the high professionalism and fast quality work. Thank you very much!
The services of the journal were excellent. The most important thing for an author is the speed of the peer review which was really fast here. They returned in a few days and immediately replied all of my questions. I want to refer this platform to all scholars. Many thanks.
We thank to the heighten science family, who speed up the publication of our article and provide every support.
In 2017, I submitted a manuscript to the journal Archives of Biotechnology and Biomedicine belonging to Heighten Science Publications Corporation. Within one week I already received the response from the editor. All processing steps were really fast so in terms of a speedy publication I can particularly recommend the journal Archives of Biotechnology and Biomedicine. The responsible contact person of the journal was always available, which gives a trustworthy impression to the author. Also the peer review process was clear and constructive. So from my experience with Heighten Science Publications Corporation I can recommend publishing there.

I, Muhammad Sarwar Khan, am serving as Editor on Archives of Biotechnology and Biomedicine (ABB). I submitted an editorial titled, 'Edible vaccines to combat Infectious Bursal Disease of poultry' for publication in ABB. After submitting the manuscript; the services rendered by the management and technical personnel to handle and process the manuscript were marvelous. Plagiarism report was shared with me with complements before reviewers' comments, All steps including article processing and service charges were well taken care of keeping in view the author's interest/preference. All together, it was an encouraging and wonderful experience working with ABB personnel.
