background: anticoagulation therapy is a routine treatment in patients with hemorrhagic cerebral venous thrombosis (cvt). however, fear of hemorrhagic complications and deterioration course following anticoagulation often disturbs the responsible physician. methods: this was a prospective observational study on consecutive cvt patients with hemorrhagic venous infarction or subarachnoid hemorrha...

abstract: minimizing the work consumed in refrigeration system is the most effective measure to reduce the cost of products in sub-ambient chemical processes. the introduction of mixed working fluids into refrigeration system in place of pure working fluids is a recent advancement applied in the field. due to the lack of systematic design method for mixed refrigerant cycle (mrc), conventional a...

Cerebral venous thrombosis (CVT) is a challenging condition because of the variability of clinical presentations. CVT can present at all ages, but is seen more in young and middle-aged women. CVT does not necessarily occur only when there is an obvious underlying etiology. In almost 30% of cases, the etiology cannot be established. CVT can present with an acute thunderclap headache, fever, seiz...

Aminopeptidase I (API) is imported into the yeast vacuole/lysosome by a constitutive non-classical vesicular transport mechanism, the cytoplasm to vacuole targeting (Cvt) pathway. Newly synthesized precursor API is sequestered in double-membrane cytoplasmic Cvt vesicles. The Cvt vesicles fuse with the vacuole, releasing single-membrane Cvt bodies containing proAPI into the vacuolar lumen, and m...

BACKGROUND Patients with isolated headache may have cerebral venous thrombosis (CVT). D-dimers are proven sensitive in excluding deep venous thrombosis (DVT) and pulmonary embolism (PE) in low risk patients. We aimed to determine whether D-dimer may play the same role in low risk CVT patients with isolated headache. METHODS We included consecutive patients suspected of CVT from our teaching h...

Cerebral venous thrombosis (CVT) is a clinical condition which is caused by the partial or complete occlusion of the dural sinuses and cerebral veins. Cases of associated CVT and multiple sclerosis (MS) have been reported and CVT development has been attributed to the previous lumbar puncture (LP) in majority of these cases. We report a case of 32-year-old woman with no previous history of rece...

BACKGROUND Cerebral venous thrombosis (CVT) is a distinct disorder with highly variable symptoms and courses. Malignancy is known to be one of the predisposing factors of CVT. CASE REPORT We present the case of a 69-year-old man with sudden behavioral changes. Brain MRI, magnetic resonance venography, and positive D-dimer assay confirmed the presence of CVT. The work-up for detecting the caus...

the facial esthetics after orthodontic treatment and orthognathic surgery may be affected by the patient's natural head position. the purpose of this study was to evaluate the natural head position for the three skeletal classes of malocclusion.our sample consisted of 102 lateral cephalometric radiographs of patients aged 15 to 18 years; class i (n=32), class ii (n=40) and class iii (n=30). nin...

Parasympathetic regulation of heart rate through the vagus nerve--often measured as resting respiratory sinus arrhythmia or cardiac vagal tone (CVT)--is a key biological correlate of psychological well-being. However, recent theorizing has suggested that many biological and psychological processes can become maladaptive when they reach extreme levels. This raises the possibility that CVT might ...
