We evaluated postural effects on intracranial pressure (ICP) and cerebral perfusion pressure [CPP: mean arterial pressure (MAP) - ICP] in neurosurgical patients undergoing 24-h ICP monitoring as part of their diagnostic workup. We identified nine patients (5 women, age 44 ± 20 yr; means ± SD), who were "as normal as possible," i.e., without indication for neurosurgical intervention (e.g., focal...
Pulmonary oedema of immersion is a rare complication of scuba diving. A case and brief discussion of the differential diagnosis and pathophysiology are presented. Onset of symptoms typically occurs during the dive, and is characterized by dyspnoea, cough and frothy sputum. Spontaneous recovery frequently occurs once the diver leaves the water. If investigated, the findings are of hypoxaemia and...
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
T HE RELATIONSHIP between the blood flow in and the position of the limbs is a matter of some clinical and physiologic interest. Clinically, it is important to know in cases of ischemic arterial disease whether the limbs have a better blood flow when they are kept horizontal on a level with the body, or are allowed to be dependent. Physiologically, it is known that when a horizontal limb is low...
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
We are describing an arthroscopy tip, which is helpful in suspected/diagnosed cases of intra-articular haemangioma of the knee. Intra-articular haemangiomas of the knee are a rare but known condition. Arthroscopy or MRI can be used for diagnosis. Arthroscopy was performed in a case of haemangioma diagnosed on MRI performed for anterior knee pain. Appearances of the haemangioma were entirely dif...
Background: Polycystic ovary syndrome (PCOS) is a multifactorial, heterogeneous, complex genetic endocrine and metabolic disorder, diagnostically characterized by chronic anovulation, polycystic ovaries and biochemical and clinical manifestations of hyperandrogenism. In patients with PCOS lower apoptotic rates found in granulosa cells compared to women with regular ovulatory cycles and this lea...
With the subject in the right lateral decubitus position, changes of central venous pressure can be recorded accurately and conveniently from a vein in the antecubital fossa of the dependent arm. Theoretically the hydrostatic pressure transforms the venous bed between the heart and the site of puncture into uninterrupted wide channels with relatively low distensibility. Simultaneous recordings ...
