To describe the macroscopic anatomy of the genital organs of the female pampas deer ( Ozotoceros bezoarticus), organs from animals dead in a captive breeding station were dissected. A total of twenty females, 17 adults and 10 pre-puberal approximately 1 year old were studied by gross dissection. The ovaries of adult ...

An increasing number of unruptured intracranial aneurysms are being detected, partly due to the increased use of brain imaging techniques. Pharmacological stabilization of aneurysms for the prevention of aneurysmal rupture could potentially be an attractive alternative approach to clipping or coiling in patients with unruptured intracranial aneurysms. We have developed ...

A 29-year-old woman with placenta increta with hemorrhage underwent uterine artery embolization using 12.5% NBCA (N-butyl 2-cyanoacrylate) diluted with iodized oil (Lipiodol). Complete resolution of placenta increta without performing curettage was obtained. The uterus returned to its normal shape, with restored endometrium, junctional zone, and myometrium. Menstruation resumed after 3 ...

Abstract  Intravenous leiomyomatosis is a rare tumor arising either from a uterine leiomyoma or from uterine vessel walls with extension into venous channels. Although intravenous leiomyomatosis is considered histologically "benign," intrusion to the cardiac chambers is almost malignant given its possibility for destruction of heart valves, extending into the pulmonary ...

Although vernix caseosa is known to be a natural biofilm at birth, human pulmonary surfactant commences to remove the vernix from fetal skin into the amniotic fluid at gestational week 34, i.e. well before delivery. To explain this paradox, we first produced two types of fluorescently labelled liposomes displaying morphology ...

Surveillance following lower extremity bypass, carotid endarterectomy, and endovascular aortic aneurysm repair has become the standard of care at most institutions. Conversely, surveillance following lower extremity endovascular interventions is performed somewhat sporadically in part because the duplex criteria for recurrent stenoses have been ill defined. It appears that duplex surveillance ...

We report a case of a 35-year-old woman who underwent uterine artery embolization (UAE) for symptomatic multiple uterine fibroids with collateral aberrant right ovarian artery that originated from the right external iliac artery. We believe that this is the first reported case in the literature of this collateral uterine flow ...

Internal carotid artery (ICA) plaques constitute one major source of retinal and cerebral brain embolism. Current guidelines recommend optimal treatment of cardiovascular risk factors and recanalization based on the degree of ICA stenosis. However, ICA plaque composition, motion, vascularization, and local hemodynamics have only received limited attention as potential and ...

The aim of this study was to investigate if increased first-trimester uterine artery Doppler resistance indices (RI) are related to stillbirth. Uterine artery Doppler indices were assessed prospectively during a routine first-trimester ultrasound scan. Patients were categorised as having a high uterine artery mean Doppler RI if the index was ...

Preeclampsia and fetal growth restriction are responsible for the majority of maternal and perinatal morbidity and mortality associated with complicated pregnancies. Although their etiologies are complex and multifactorial, both are associated with increased uterine artery resistance. Sildenafil citrate is able to rescue the dysfunction observed ex vivo in uterine arteries ...

Objective. It is well known that the nasal cavity and paranasal sinuses affect the acoustic characteristics of the voice as resonators. Any expansion in nasal valve area, the narrowest segment of the nasal cavity, affects the nasal resistance and therefore has the potential to alter the nasalance. The aim of ...

Mitral valve replacement (MVR) in the presence of the extensive calcification of the mitral annulus is a technical challenge. The heavily calcified annulus can cause great difficulty in the insertion of a prosthetic valve and periprosthetic leakage later on. Vigorous annular decalcification may cause circumflex coronary artery injury, atrioventricular rupture ...

The posterior circumflex humeral artery (PCHA) travels together with the axillary nerve through the quadrilateral space of the shoulder. Angiographic occlusion of this artery upon abduction and external rotation (ABER) of the arm has been accepted as evidence of mechanical compression of the axillary nerve and thus considered pathognomonic of ...

Sutureless vascular anastomoses have been the subject of extensive research for decades. In neurosurgery the need for a safe and fast technique is high, because temporary occlusion of cerebral arteries may rapidly lead to brain ischemia. Conventional sutured anastomoses have always been the golden standard. Limited working space and difficult ...

We aimed to define the relationship between cerebral atherosclerosis and stroke after coronary artery bypass grafting (CABG). Although cerebral atherosclerosis may play a crucial role in the advent of post-CABG stroke, only extracranial carotid artery disease has been extensively studied, and the effects of atherosclerosis on the mechanisms underlying post-CABG ...

Insults during the fetal period predispose the offspring to systemic cardiovascular disease, but little is known on the pulmonary circulation and the underlying mechanisms. Maternal undernutrition during pregnancy may represent a model to investigate underlying mechanisms, because it is associated with systemic vascular dysfunction in the offspring in animals and ...

Background- Lung hypoplasia and persistent pulmonary hypertension of the newborn limit survival in congenital diaphragmatic hernia (CDH). Unlike other diseases resulting in persistent pulmonary hypertension of the newborn, infants with CDH are refractory to inhaled nitric oxide (NO). Nitric oxide mediates pulmonary vasodilatation at birth in part via cyclic GMP ...

Upper-extremity deep venous thrombosis is less common than lower-extremity deep venous thrombosis. However, upper-extremity deep venous thrombosis is associated with similar adverse consequences and is becoming more common in patients with complex medical conditions requiring central venous catheters or wires. Although guidelines suggest that this disorder be managed using approaches ...

Stachybotrys chartarum, a ubiquitous fungus in our environment, has been suspected of causing respiratory symptoms in humans, such as acute infant pulmonary hemorrhage and asthma. We previously established a mouse model in which repeated inhalation of Stachybotrys chartarum spores caused pulmonary hypertension. To further investigate the model, particularly in the ...

Pulmonary hypertension and right ventricular failure are major contributors to morbidity and mortality in chronic lung disease. Therefore, large animal models of pulmonary hypertension and right ventricular hypertrophy are needed to study underlying disease mechanisms and test new treatment modalities. The objective of this study was to create a low-mortality ...

Increased aortic pulse wave velocity (PWV) reflects increased arterial stiffness and is a strong predictor of cardiovascular risk in chronic kidney disease (CKD). We examined functional and structural correlations between PWV, aortic calcification and vascular remodelling in a rodent model of CKD, the Lewis Polycystic Kidney (LPK) rat. Haemodynamic parameters ...

Pulmonary vascular disease embodies all congenital or acquired pathologies that affect the pulmonary vasculature. One of them is pulmonary hypertension of the newborn (PHN), which is clinically characterized by a persistent high pulmonary vascular resistance postnatally and an abnormal vascular response. Morphologically, the vascular walls of the small pulmonary arteries ...

Abstract To date, transcatheter valve implantation is limited to the replacement of pulmonary and aortic valves. The aim of this study was to analyze a valved stent for minimally invasive implantation in the mitral position. A self-expanding mitral valved stent was designed for transapical implantation. Thirty pigs underwent off-pump mitral ...

The role of generalized hypoxia-ischemia in the genesis of perinatal focal arterial stroke remains puzzling. Animal studies have demonstrated that hypoxia-ischemia may alter blood flow through the ductus venosus, thereby increasing the risk for placental emboli entering the cerebral circulation. A retrospective review was performed of clinical records of all ...
