Equilibrium structures and energies of gas-phase molecular complexes SiH(4)···BH(3), SiH(4)···B(2)H(6), and SiH(4)···BCl(3) were determined using second-order Møller-Plesset perturbation theory (MP2) and the aug-cc-pVTZ basis set, with and without explicit core electron correlation. Single-point energies were calculated for the MP2-optimized structures using MP2 with the aug-cc-pVQZ basis set a...

< p>In this communication, we have reported that the Pd(OAc)2–Et3SiH-DMF system promotes the microwave-assisted chemoselective reduction of aryl α,β-unsaturated esters in good yields. The protocol affords a convenient reduction of aryl-conjugated double bonds even in presence of other functional groups like esters, phenols, and ethers.

We applied the recent International Headache Society (IHS) criteria for headache related to spontaneous intracranial hypotension (SIH) to 90 consecutive patients with a final diagnosis of SIH confirmed by cerebral magnetic resonance imaging with contrast. Orthostatic headache (developing within 2 h of standing or sitting up) was present in 67 patients (75%) but appeared within 15 min after stan...

BACKGROUND Malignant pleural effusion (MPE) occurs at a terminal stage of cancer, and related symptoms may considerably reduce a patient's respiratory function and quality of life. We assessed the benefit of simple intrapleural hyperthermia (SIH) during thoracoscopic exploration for MPE. METHODS We conducted a retrospective review of 34 patients underwent thoracoscopic exploration and SIH pro...

BACKGROUND Spontaneous intracranial hypotension (SIH) and related headache after intrathecal pump implantation is a possibility. Knowing the exact location of the cerebrospinal fluid (CSF) leak is mandatory for managing with interventional therapies. OBJECTIVES Radioisotope cisternography (RICG) is a common procedure in nuclear medicine and may be used as an additional procedure in the differ...

Background. Undiagnosed intracranial hypotension can result in several complications including subdural hematoma (SDH), subarachnoid hemorrhage (SAH), dural venous sinuses thrombosis (CVT), cranial nerve palsies, and stupor resulting from sagging of the brain. It is rare to see all the complications in one patient. Furthermore, imaging of the brain vasculature may reveal incidental asymptomatic...

The aim of this study was to analyze the ECG time intervals in the course of the development of chronic anthracycline cardiomyopathy in rabbits. Furthermore, this approach was employed to study the effects of a model cardioprotective drug (dexrazoxane) and two novel iron chelating compounds--salicylaldehyde isonicotinoyl hydrazone (SIH) and pyridoxal 2-chlorobenzoyl hydrazone (o-108). Repeated ...

Spontaneous Intracranial Hypotension (SIH) was first described over 60 years ago by Schaltenbrand and termed “aliquorrhea”1. In 1997, this syndrome was defined by a classical triad of postural headaches, low cerebral spinal fluid (CSF) pressure and imaging abnormalities2. More recent evidence has redefined this concept and our understanding of the pathological mechanism, as well as the variable...

Spontaneous intracranial hypotension (SIH) is a syndrome in which a cerebrospinal fluid leak occurs within the spinal axis, and may lead to a constellation of neurological symptoms. A postural or orthostatic headache is the most common of these symptoms1. Spontaneous intracranial hypotension was first recognized by Georg Schaltenbrand in the 1930s. Many terms have been used to describe the cond...

Purpose: We evaluated the MRI finding of pachymeningeal enhancement in patients with intracranial hypotension and head trauma with particular attention to differential findings and change in follow-up study, and in order to support the knowledge about the pathophysiology of d ural enhancement. Materials and Methods : The findings of enhanced brain MRI offifteen patients who showed diffuse pachy...
