HPA-axis regulation at in-patient admission is associated with antidepressant therapy outcome in male but not in female depressed patients. | A concatenation of data implicates a hyperactivity of the hypothalamus pituitary adrenal (HPA)-axis in the pathogenesis of depression and its normalization as a necessary predecessor of clinical response to antidepressant drugs. In addition, regulation of the HPA-axis has been shown to be dependent on sex hormones. We ... | 18,829,172 |
A new probe for targeting drug delivery system. | Recently, TDDS (Targeting drug delivery system) plays an important role in enhancing the bioavailability and targeting of anti-tumor drugs. How to transport drugs quickly and precisely to their target sites of action has not been solved fundamentally. A large number of researches have identified artemisinin and its ana... | 18,829,175 |
Stature and gender estimation using foot measurements. | In forensic investigation difficulties are being experienced in the stature and gender estimation of bodies dismembered in mass destruction. So as to eliminate these difficulties, new methods are being developed. The aim of this study is to develop formulae for estimation of the stature and gender through foot measurem... | 18,829,191 |
Deep vein thrombosis resolution is impaired in diet-induced type 2 diabetic mice. | Type 2 diabetes mellitus results in a procoagulant and thrombogenic state that could predispose diabetic individuals to develop venous thrombosis. We sought to determine whether diet-induced type 2 diabetes mellitus affects deep venous thrombosis (DVT) resolution in a murine model. C57Bl/6 mice were fed a low-fat or a ... | 18,829,216 |
Incidence of ipsilateral postoperative deep venous thrombosis in the amputated lower extremity of patients with peripheral obstructive arterial disease. | Patients undergoing amputation of the lower limb due to peripheral arterial disease (PAD) are at risk of developing deep venous thrombosis (DVT). Few studies in the research literature report the incidence of DVT during the early postoperative period or the risk factors for the development of DVT in the amputation stum... | 18,829,221 |
Prevalence of carotid stenosis and silent myocardial ischemia in asymptomatic subjects with a low ankle-brachial index. | Subjects with symptomatic peripheral artery disease (PAD) have an elevated prevalence of carotid stenosis and of silent myocardial ischaemia. As such, clinical guidelines advocate the detection of sub-clinical vascular disease in this population. However, the prevalence of occult vascular disease in asymptomatic patien... | 18,829,225 |
Validation of a method for determination of the ankle-brachial index in the seated position. | To validate a method for determination of the ankle-brachial index (ABI) in the seated position. Peripheral arterial disease (PAD) is a prevalent disorder that is associated with quality of life impairment and increased risk of a major cardiovascular event. The ABI is the initial test for screening and diagnosis of PAD... | 18,829,231 |
Duplex ultrasound in aneurysm surveillance following endovascular aneurysm repair: a comparison with computed tomography aortography. | Cumulative radiation dose, cost, and increased demand for computed tomography aortography (CTA) suggest that duplex ultrasonography (DU) may be an alternative to CTA-based surveillance. We compared CTA with DU during endovascular aneurysm repair (EVAR) follow-up. Patients undergoing EVAR had clinical and radiological f... | 18,829,237 |
Outcomes of endovascular abdominal aortic aneurysm repair compared with open surgical repair in high-risk patients: results from the Swedish Vascular Registry. | The management of infrarenal aortic aneurysms in high-risk patients remains a challenge. Endovascular aneurysm repair (EVAR) is associated with superior short-term mortality rates but unclear long-term results and has not been shown to improve survival in patients unfit for open repair (OR). The aim of this population-... | 18,829,239 |
[Immunosuppressants for auto-immune diseases and pregnancy]. | Therapeutic stability of a systemic disease is a priority during pregnancy. To stop an effective treatment, to reduce dosages or to switch to less effective treatments might induce some loss of chance for pregnant women, and eventually harmful consequences for fetuses. Due to the teratogenic effects of some immunosuppr... | 18,829,249 |
A factor analytic comparison of five models of PTSD symptoms. | This study examined the factor structure of PTSD symptoms in a sample of college students (n=344) reporting exposure to a range of traumatic events. The sample was randomly split and an exploratory factor analysis was conducted with half of the sample. The factor structure obtained in the exploratory analysis was evalu... | 18,829,253 |
Vulnerability of the frontal-temporal connections in temporal lobe epilepsy. | In temporal lobe epilepsy (TLE), frontal-temporal connections are integral parts of the epileptogenic network. Although frontal-temporal gray matter abnormalities have been consistently demonstrated in TLE, white matter connections between these two lobes require further study in this disease setting. We therefore inve... | 18,829,258 |
