In this paper, we developed a high-performance solid-state pH sensor using a Ce0.9Sr0.1(Zr0.53Ti0.47)O4 (CSZT) membrane through a very simple sol–gel spin-coating process. The structural properties of the CSZT membrane are correlated with its sensing characteristics. The CSZT based EIS sensor exhibited a high pH sensitivity of 92.48 mV pH−1, which is beyond the Nernst limit (59.4 mV pH−1), and good reliability in terms of a low hysteresis voltage of 1 mV and a small drift rate of 0.15 mV h−1. This behaviour is attributed to the incorporation of Sr in the CSZT sensing membrane, which promotes change in the Ce oxidation state from Ce4+ to Ce3+.We developed a high-performance solid-state pH sensor using a Ce0.9Sr0.1(Zr0.53Ti0.47)O4 (CSZT) membrane through a very simple sol–gel spin-coating process. 相似文献

Anorectal suppurations are quite common. Supralevator abscesses, previously regarded as a rare subgroup, were seen in 9.1
per cent of 506 patients admitted to Cook County Hospital in a two-year period. Aggressive supportive management was followed
by early, adequate drainage through single or multiple radial perianal incisions or through the rectum whenever indicated.
When fistulas were identified, either a primary fistulotomy or a two-stage fistulotomy using a seton was performed in the
majority of cases. Important factors in the prevention of morbidity and mortality included debridement of all necrotic tissue,
careful bacteriologic studies and judicious use of antibiotics, close postoperative observation, and long-term follow-up of
the patients.

Perianal abscesses and fistulas 总被引:2,自引:0,他引:2
Paravasthu S. Ramanujam M.D. M. Leela Prasad M.D. Dr. Herand Abcarian M.D. Ana B. Tan R.N. E.T. 《Diseases of the colon and rectum》1984,27(9):593-597
In a five and one-half year period, 1023 patients with anorectal abscesses and fistulas were treated. Under regional anesthesia
the abscesses were unroofed and debrided and a primary fistulotomy was performed whenever a low fistula was identified. In
355 (34.7 per cent) an internal fistulous opening was demonstrated at the time of abscess drainage. Thirty-two patients had
suprashincteric fistulas and underwent two-stage fistulotomy using a seton. Perianal abscesses were encountered in 42.7 per
cent of the patients, followed by ischiorectal (22.7 per cent), intersphincteric (21.4 per cent), and supralevator (7.33 per
cent). The patients with supralevator and intersphincteric abscesses had a high incidence of fistula identified during abscess
drainage. The recurrence rates were 3.7 per cent in the group with abscess drainage only and 1.8 per cent in the group that
had primary fistulotomy along with abscess drainage. The follow-up period averaged 36 months. To accomplish adequate drainage
and identify the deeper components and associated fistulous opening (34.7 per cent of the entire group), careful examination
under regional anesthesia is recommended. Early aggressive treatment of an anorectal abscess and fistula significantly reduces
the possibility of recurrent abscesses and/or the need for further surgery.

Over the years, lipids of non-pathogenic yeast such as Saccharomyces cerevisiae have been characterized to some details; however, a comparable situation does not exist for the human pathogenic fungi. This review is an attempt to bring in recent advances made in lipid research by employing high throughput lipidomic methods in terms of lipid analysis of pathogenic yeasts. Several pathogenic fungi exhibit multidrug resistance (MDR) which they acquire during the course of a treatment. Among the several causal factors, lipids by far have emerged as one of the critical contributors in the MDR acquisition in human pathogenic Candida. In this article, we have particularly focused on the role of lipids involved in cross talks between different cellular circuits that impact the acquisition of MDR in Candida. 相似文献

Antibiotic acyldepsipeptide (ADEP) targets the bacterial ClpP serine protease and can inhibit the growth of numerous bacterial species by activating/dysregulating the protease activity within the cell. The spirochete Leptospira interrogans harbors two ClpP isoforms (LepClpP1 and LepClpP2). Supplementation of ADEP in the Leptospira growth medium resulted in the inhibition of bacterial growth. The ADEP mediated activation of the LepClpP mixture was dependent on the time allowed for the self-assembly of LepClpP1 and LepClpP2. The dynamic light scattering of the LepClpP mixture in the presence of the ADEP indicated a conformational transformation of the LepClpP machinery. Serine 98, a catalytic triad residue of the LepClpP1 in the LepClpP1P2 heterocomplex, was critical for the ADEP mediated activation. The computational prototype of the LepClpP1P2 structure suggested that the hydrophobic pockets wherein the ADEPs or the physiological chaperone ClpX predominantly dock are exclusively present in the LepClpP2 heptamer. Using the ADEP as a tool, this investigation provides an insight into the molecular function of the LepClpP1P2 in a coalition with its ATPase chaperone LepClpX. The shreds of the evidence illustrated in this investigation verify that ADEP1 possesses the ability to control the LepClpP system in an unconventional approach than the other organisms. 相似文献

Hemorrhagic complications are uncommon after percutaneous transhepatic biliary drainage. The presenting features include bleeding through or around the drainage catheter, hematemesis or melena. Diagnosis requires cholangiography, CT angiography or conventional angiography. Minor venous hemorrhage is managed by catheter repositioning, clamping or upgrading to a larger bore catheter. Major vascular injuries require percutaneous or endovascular procedures like embolization or stenting. A complete knowledge of these complications will direct the interventional radiologist to take adequate precautions to reduce their incidence and necessary steps in their management. This review presents and discusses various hemorrhagic complications occurring after percutaneous transhepatic biliary drainage along with their treatment options and suggests a detailed algorithm. 相似文献
