Background—Adrenergic agents are commonly used in the treatment of chronic orthostatic intolerance with postural tachycardia syndrome (POTS). POTS may be associated with increased limb blood flow (“high flow”) and defective orthostatic vasoconstriction or decreased limb blood flow (“low flow”) and potentially with small blood volume. Methods and Results—We investigated the consequences of short...

Purpose: Breast Cancer (BC) is considered as one of the most dangerous diseases, especially in women. The survivability patient a challenging task if breast cancer severe stage. It very much essential for early classification ultrasound images (BUIs) into several categories such benign (BN), malignant (MG) and normal (NL), etc. so that preventive measures can be taken accordingly at earliest. A...

Although the left posterior occipitotemporal sulcus (pOTS) has been called a visual word form area, debate persists over the selectivity of this region for reading relative to general nonorthographic visual object processing. We used high-resolution functional magnetic resonance imaging to study left pOTS responses to combinatorial orthographic and object shape information. Participants perform...

Postural orthostatic tachycardia syndrome (POTS) commonly affects women of childbearing age. We report on a 37-year-old woman who developed symptoms of recurrent syncope in the postpartum period. Her head up tilt test and clinical presentation was consistent with POTS.

Sugarcane is an important resource for bioenergy. Fields are usually established by using 15-20 cm pieces of sugarcane stalks as propagation material. An alternative method is to use small chips with nodes from sugarcane stalks. Plants from nodes are often established in plastic pots, but plastic pots could be replaced with biodegradable paper pots. This would be a more sustainable solution, re...

BACKGROUND AND AIMS Is the release of allelochemicals by the dominant tussock grass Festuca paniculata responsible for its dominance by inhibiting growth of neighbour grasses in subalpine grasslands? As such a community is also structured by mowing practices, what could be the impact of mowing on allelopathy? METHODS A design was used that isolated allelopathy from resource competition by sep...

Efficient extraction of shape information is essential for proficient reading but the role of cortical mechanisms of shape analysis in word reading is not well understood. We studied cortical responses to written words while parametrically varying the amount of visual noise applied to the word stimuli. In only a few regions along the ventral surface, cortical responses increased with word visib...

OBJECTIVES To evaluate whether the use of adult heart rate (HR) criteria is appropriate for diagnosing orthostatic intolerance (OI) and postural tachycardia syndrome (POTS) in children and adolescents, and to establish normative data and diagnostic criteria for pediatric OI and POTS. STUDY DESIGN A total of 106 normal controls aged 8-19 years (mean age, 14.5±3.3 years) underwent standardized ...
