The interaction between (sub)monolayers of the ionic liquid 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide [BMP](+)[TFSA](-) and graphite(0001), which serves as a model for the anode|electolyte interface in Li-ion batteries, was investigated under ultrahigh vacuum conditions in a combined experimental and theoretical approach. High-resolution scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), and dispersion-corrected density functional theory (DFT-D) calculations were employed...

Patients with malignancies commonly experience abnormalities in serum electrolytes, including hyponatremia, hypokalemia, hyperkalemia, hypophosphatemia, and hypercalcemia. In many cases, the causes of these electolyte disturbances are due to common etiologies not unique to the underlying cancer. However, at other times, these electrolyte disorders signal the presence of paraneoplastic processes and portend a poor prognosis. Furthermore, the development of these electrolyte abnormalities may be associated with symptoms that can negatively affect quality of life and may prevent certain chemotherapeutic regimens...

Cushing's syndrome is a rare condition in the general population (1/1000000) and is even less common during pregnancy. We report the case of a patient cared at 27 weeks of gestation (wg) for hypertension and electolyte disturbances. Cushing's syndrome was confirmed by salivary cortisol and ACTH assessment. RMN revealed a 9 cm left adrenal tumor. Severe hypertension and electolyte disturbances on the one hand, and diagnostic uncertainty on the other hand, imposed adrenalectomy at 29 wg. Twelve days later, fetal distress led to a caesarian section and birth of a well being male baby...

BACKGROUND/AIM: Surgical treatment is the only method of abdominal aorta aneurysm (AAA) treatment. According to data of the available literature, elective open, i.e., conservative, reconstruction (OR) is followed by 3%-5% mortality, as well as by numerous comorbide conditions inside the early postoperative course (the first 30 days after the surgery) that occur in 20%-30% of the operated on. The aim of the study was to present preliminar results of a comparative clinical retrospective study of early postoperative morbidity and mortality in AAA reconstruction using endovascular (EVAR) and open surgical techniques...

OBJECTIVE: To investigate effects of IV administration of propafenone for naturally occurring and experimentally induced chronic atrial fibrillation in horses. ANIMALS: 2 horses with naturally occurring atrial fibrillation and 4 horses with pacing-induced atrial fibrillation. PROCEDURES: Horses received a bolus of propafenone (2 mg/kg, IV over 15 minutes). If atrial fibrillation persisted after 20 minutes, a continuous infusion of propafenone (7 microg/kg/min) was given for 120 minutes...

Calcium-selective ion channels are known to have carboxylate-rich selectivity filters, a common motif that is primarily responsible for their high Ca(2+) affinity. Different Ca(2+) affinities ranging from micromolar (the L-type Ca channel) to millimolar (the ryanodine receptor channel) are closely related to the different physiological functions of these channels. To understand the physical mechanism for this range of affinities given similar amino acids in their selectivity filters, we use grand canonical Monte Carlo simulations to assess the binding of monovalent and divalent ions in the selectivity filter of a model Ca channel...

Carotid-cavernous fistulae are abnormal communications between the internal carotid artery and venous compartments of the cavernous sinus. Fistulae are uncommon but well-documented sequelae of craniofacial trauma. The characteristic clinical presentation includes ocular pain, chemosis, exophthalmus and visual disturbances. We report on a 28-year-old man with a history of severe craniocerebral injury, including multiple craniofacial fractures resulting from a fall from a height of approximately 6 meters, who was surgically treated one year ago...

BACKGROUND: The concentrations of ionized calcium (iCa) and ionized magnesium (iMg) were measured in the cerebrospinal fluid (CSF) of convulsive and non-convulsive children, to investigate the relationship between seizure manifestation and CSF iCa and iMg concentrations. Standard concentrations of CSF iCa and iMg were also established. METHODS: CSF samples from 23 patients, ages 0-15 years, with various forms of seizures and 26 age-matched non-convulsive children were collected by lumbar puncture...

Our case is a 50-year-old man with angina and chronic renal failure. He underwent double vessel MIDCAB (LITA-LAD and GEA-SVG-RCA). Postoperative course was uneventful and postoperative angiography revealed patent grafts. MIDCAB is thought to be effective for patients who have chronic renal failure, because they are able to resume hemodialysis in early postoperative period for controlling water and electolyte.

In order to explore the role of brain atrial natriuretic peptide (ANP) in regulating water and electrolytes, the changes of the ANP content of various brain areas in the status of high salt intake and in 3/4 nephrectomy rats. In control group, a wide distribution of ANP was observed in different areas of the brain. The amount of daily water intake and urine were larger, and urine sodium concentration was lower in the 3/4 nephrectomy group than those in the control group (P < 0.05). In the ten nuclei we have studied, ANP content was not significantly different from that of the control (P > 0...

Cut, polished surfaces of human teeth were exposed to acetate buffers, pH 5.2, with a background electolyte composition similar to plaque fluid and with - log10 (ion-activity product) for hydroxyapatite, pIHA, ranging from 55 to 62, at 37 degrees C under a 5% v/v CO2 atmosphere. Demineralization was assessed by scanning electron microscopy of the treated surfaces and of methacrylate replicas of subsurface pores. Intertubular dentine was slightly soluble at pIHA 55, while peritubular dentine was less soluble, dissolving at pIHA > or = 58...

A 49-year-old male with primary aldosteronism, accompanied by hypertrophic cardiomyopathy (HCM), underwent our anesthesiological management for resection of a left adrenal tumor. The preoperative examination revealed hypertension, mild nephropathy and hypokalemia. Spilnolactone treatment was discontinued 3 days before surgery. In the operating room, a Swan-Ganz catheter was inserted for monitoring hemodynamic parameters. Anesthesia was maintained with nitrous oxide-oxygen-isoflurane and vecuronium. During the surgery, prostaglandin E1 and nitroglycerin were used as vasodilators...

Brain insult in neurosurgical patients is highly dependent on hydroelectrolytic and haemodynamic disturbances. The magnitude of their effect is related to blood-brain barrier integrity and characteristics of cerebral perfusion pressure. Moderate disturbances in ionic balance or CPP may lead to interstitial oedema or worsening of cerebral ischaemia. As a consequence, intracranial pressure (ICP) may rise and neurological status worsen. This study discusses the cerebral effects of intercompartimentary water and electrolyte movements, which themselves are either secondary to early neurological dysfunction, as insipid diabetes, the syndrome of inappropriate ADH secretion, and/or to renal losses of sodium, or iatrogenic, after administration of mannitol or furosemide...

From July 1985 through January 1986, 43 patients underwent urinary diversion that included creation of a continent reservoir from an ileal segment, according to the method described originally by Kock. An important modification included removal of a narrow strip of mesentery for 8 cm along the afferent and efferent limbs of the pouch to allow adequate ileal intussusception and fixation of the nipple valves to prevent reflux and to ensure continence. A strip of PGA mesh serves as a collar to fix the afferent-efferent limb to the pouch once the intussusception technique has been accomplished...

The authors devised a new handy apparatus for iontophoresis in order to prevent pulp irritation caused by tooth reduction. This study was intended to observe the ability of the device. 8% zinc chloride solution was iontophoresed in the dentin of extracted human and bovine teeth by the device. Then, the dye and microbial invasion tests were carried out to investigate how effectively it could seal the dentinal tubules. The following conclusions were drawn: 1. By the zinc iontophoresis, the zinc briefly penetrated into the deep portion of the dentin...
