in this paper, we deal with the subdierential concept onhadamard spaces. flat hadamard spaces are characterized, and nec-essary and sucient conditions are presented to prove that the subdif-ferential set in hadamard spaces is nonempty. proximal subdierentialin hadamard spaces is addressed and some basic properties are high-lighted. finally, a density theorem for subdierential set is establi...

BACKGROUND No single pulmonary-specific variable, including the severity of hypoxemia, has been found to predict the risk of death independently when measured early in the course of the acute respiratory distress syndrome. Because an increase in the pulmonary dead-space fraction has been described in observational studies of the syndrome, we systematically measured the dead-space fraction early...

A 60-year-old man complaining of diplopia and vertigo showed bilateral medial longitudinal fasciculus (MLF) syndrome. The CT scan revealed a space-occupying lesion with watery fluid in the left cranial fossa, which was divided into two parts by a thin septum. Surgical trepanation was performed followed by 4 weeks of prednisolone therapy. He was completely cured 5 months later. The plausible cau...

A study published in the previous issue of Critical Care demonstrates that measurement of the pulmonary dead-space fraction is superior to hypoxemia as an indicator of a favorable physiologic response to prone positioning in patients with severe acute respiratory distress syndrome. These results add to the growing evidence supporting the clinical and research value of measuring pulmonary dead s...

The deep midpalmar space of the hand communicates with the space of Parona in the forearm. Infection of these deep spaces can be difficult to diagnose. This article presents the first reported case of acute compartment syndrome of the forearm secondary to infection within the space of Parona. This article discusses the anatomy of the space of Parona, highlighting its communicating spaces and th...

introduction of modern architecture in iran and its popularization in 1950s and after, brought some new concepts in everyday life of iranian women, among which was “kitchen as heart of home-life”. younger members of current generation are grown in these modernized spaces while a bit older ones have experienced houses of traditional style. this study is designed to explore what previous concept ...

Vitamin D-dependent rickets type I (VDDRI) represents an autosomal recessive hereditary defect in vitamin D metabolism. Patients with VDDRI have mutations of chromosome 12 that affect the gene for the enzyme 1-alpha-hydroxylase, resulting in decreased levels of 1,25(OH)(2) vitamin D. Clinical features include growth failure, hypotonia, weakness, rachitic rosary, convulsions, tetany, open fontan...
