BACKGROUND Elevated left ventricular mass (LVM) is a strong predictor of negative cardiovascular outcomes, including heart failure, stroke, and sudden cardiac death. A relationship between close (< 50 m compared with > 150 m) residential proximity to major roadways and higher LVM has previously been described, but the mechanistic pathways that are involved in this relationship are not known. Un...
Graph analytics algorithms leverage quantifiable structural properties of the data to predict interesting concepts and relationships. The same information, however, can be represented using many different structures and the structural properties observed over particular representations do not necessarily hold for alternative structures. Because these algorithms tend to be highly effective over ...
background and aims. although salivary gland tumors are not very common, early diagnosis and treatment is crucial because of their proximity to vital organs, and therefore, determining the efficacy of new imaging procedures becomes important. this study aimed to evaluate the efficacy of magnetic resonance imaging (mri) and color doppler ultrasonography parameters in the diagnosis and differenti...
Reconstruction of the lower limb presents a complex problem after skin cancer surgery, as proximity of skin and bone present vascular and technical challenges. Studies on vascular anatomy have confirmed that the vascular plane on the lower limb lies deep to the deep fascia. Yet, many flaps are routinely raised superficial to this plane and therefore flap failure rates in the lower limb are high...
The highly branched nervous and vascular systems run along parallel trajectories throughout the human body. This stereotyped pattern of branching shared by the nervous and vascular systems stems from a common reliance on specific cues critical to both neurogenesis and angiogenesis. Continually emerging evidence supports the notion of later-evolving vascular networks co-opting neural molecular m...
Vascular anomalies are localized defects in the vasculature that may or may not be present at birth. There are many types of vascular anomalies with different aetiology and clinical picture and, therefore, require the combined expertise of medical, radiological, and surgical specialities for its diagnosis and management. The term "haemangioma" is used as a common generic label to incorporate al...
Juvenile nasopharyngeal angiofibromas (JNA) are rare, benign, highly vascular tumors which appear in proximity to the sphenopalatine foramen. The tumor arises most commonly in adolescent males suggesting that in could be hormonally responsive. Although it is histologically benign, it has a high destructive potential and a high grade of recurrence. It is a fibrous vascular tumor with vascular so...
ارزیابی اثر داروی انروفلوکساسین بر فرایند آنژیوژنز با استفاده از مدل غشاء کوریوآلانتوئیک جنین ماکیان
چکیده به منظور ارزیابی تأثیر داروی انروفلوکساسین بر روی فرایند آنژیوژنز، تخم مرغ های نژاد راس (میانگین وزن 4±55 گرم) انکوبه شدند. در روز چهارم انکوباسیون، یک پنجره ی 5/1×1 سانتی متری در محور طولی ایجاد شد و تخم مرغ ها به دو گروه تقسیم شدند (7 تخم مرغ در هر گروه). در روز 7، انروفلوکساسین (mg/ky egg weight 10) در گروه درمان، روی پرده کوریوآلانتوئیک تلقیح شد و گروه کنترل pbs دریافت کردند. سه روز ...
When acquiring the surface data of the sample part, it is not easy to get the full data on one scan due to the configuration or topology of the part. In addition, some special parts have special assembly request, for example the joint surface smooth and the boundary share. The process usually requires multiple scans for an assembly model. Some identical points have different coordinate data bec...
