BACKGROUND: Evaluation of nociceptive-antinociceptive balance during general anesthesia is still challenging and routinely based on clinical criteria. Analgesic drug delivered may be optimized with parasympathetic tone activity (PTA) monitor. This study compares ketorolac and ketorolac/tramadol balance analgesia using a PTA monitor. METHODS: Pain intensity response was assessed using a 0-100 numerical state scale (PTA) after nociceptive stimuli in pigs under stable sevoflurane anesthesia...

PURPOSE OF REVIEW: Pancreas transplantation in type 2 diabetes mellitus (T2DM) candidates remains disproportionately lower than in type 1 diabetes mellitus (T1DM); however, outcomes in carefully selected patients mirrors that of T1DM. Despite the 2014 United Network for Organ Sharing (UNOS) eligibility criteria for simultaneous pancreas/kidney transplant (SPK) transplantation in T2DM patients, an expected increase in the number of transplants was not observed. RECENT FINDINGS: In an updated International Pancreas and Transplant Registry (IPTR) analysis, 1514 primary deceased donor pancreas transplants were performed in T2DM recipients [1995-2015, SPK 88%, pancreas after kidney (PAK) 9%, pancreas transplant alone (PTA) 3%]...

Objectives: To investigate the population pharmacokinetics (PK) of amoxicillin in ICU burn patients and the optimal dosage regimens. METHODS: Prospective study involving 21 consecutive burn patients receiving amoxicillin. PK data were analysed using non-linear mixed effects modelling. Monte-Carlo simulations assessed the influence of various amoxicillin dosage regimens with identified covariates on the probability to achieve a target (PTA) value of time during which free amoxicillin concentrations in plasma exceeded the minimal inhibitory concentration ( f T>MIC)...

REVIEW
Chulwoo Park, Woojun Park
Many petroleum-polluted areas are considered as extreme environments because of co-occurrence of low and high temperatures, high salt, and acidic and anaerobic conditions. Alkanes, which are major constituents of crude oils, can be degraded under extreme conditions, both aerobically and anaerobically by bacteria and archaea of different phyla. Alkane degraders possess exclusive metabolic pathways and survival strategies, which involve the use of protein and RNA chaperones, compatible solutes, biosurfactants, and exopolysaccharide production for self-protection during harsh environmental conditions such as oxidative and osmotic stress, and ionic nutrient-shortage...

The ability to remember and to navigate to safe places is necessary for survival. Place navigation is known to involve medial entorhinal cortex (MEC)-hippocampal connections. However, learning-dependent changes in neuronal activity in the distinct circuits remain unknown. Here, by using optic fiber photometry in freely behaving mice, we discovered the experience-dependent induction of a persistent-task-associated (PTA) activity. This PTA activity critically depends on learned visual cues and builds up selectively in the MEC layer II-dentate gyrus, but not in the MEC layer III-CA1 pathway, and its optogenetic suppression disrupts navigation to the target location...

Acid-catalyzed skeletal C-C bond isomerizations are important benchmark reactions for the petrochemical industries. Among those, o-xylene isomerization/disproportionation is a probe reaction for strong Brønsted acid catalysis, and it is also sensitive to the local acid site density and pore topology. Here, we report on the use of phosphotungstic acid (PTA) encapsulated within NU-1000, a Zr-based metal-organic framework (MOF), as a catalyst for o-xylene isomerization at 523 K. Extended X-ray absorption fine structure (EXAFS), 31P NMR, N2 physisorption, and XRD show that the catalyst is structurally stable with time-on-stream, and that WOx clusters are necessary for detectable rates, consistent with conventional catalysts for the reaction...

Clostridium ljungdahlii has emerged as an attractive candidate for the bioconversion of synthesis gas (CO, CO2 , H2 ) to a variety of fuels and chemicals through the Wood-Ljungdahl pathway. However, metabolic engineering and pathway elucidation in this microbe is limited by the lack of genetic tools to downregulate target genes. To overcome this obstacle, here we developed an inducible CRISPR interference (CRISPRi) system for C. ljungdahlii that enables efficient (>94%) transcriptional repression of several target genes, both individually and in tandem...

BACKGROUND: ʟ-Ornithine is an important amino acid with broad applications in pharmaceutical and food industries. Despite lagging ʟ-ornithine productivity and cost reduction, microbial fermentation is a promising route for sustainable ʟ-ornithine production and thus development of robust microbial strains with high stability and productivity is essential. RESULTS: Previously, we systematically developed a new strain, SO1 originate from Corynebacterium glutamicum S9114, for ʟ-ornithine production...

We report three primary thyroid angiosarcoma (PTA) cases revealing distinctive morphological features. A systematic literature review completed our analysis to evaluate the most important morphological factors for predicting prognosis in PTAs. Three rare PTA cases were analysed. In addition, we identified 46 previously reported PTAs with available follow-up data to compare morphological features related to prognosis between patients with a favourable <i><i><i><i>versus</i></i></i></i> aggressive outcome...

Objective: To establish the rate of clinical recurrence of critical limb ischemia (CLI) in diabetic patients with ischemic foot ulcers (DFUs) treated by percutaneous transluminal angioplasty (PTA). Approach: The study group was composed of 304 patients with ischemic DFUs treated by PTA. We evaluated the rate of clinical recurrence of CLI requiring a second PTA (repeated PTA [rePTA]), the factors related to CLI relapse, and the outcomes of rePTA patients. The follow-up was 12.5 ± 6.6 months. Results: Seventy-four of 304 patients (24...

BACKGROUND: Patients with a single hepatocellular carcinoma (HCC) ≤3 cm and preserved liver function have the highest likelihood to be cured if treated. The most adequate treatment methods are yet a matter that is debated. METHODS: We reviewed the literature about open anatomic resection (AR), laparoscopic liver resection (LLR), and percutaneous thermal ablation (PTA). RESULTS: PTA is effective as resection for HCC < 2 cm, when they are neither subcapsular nor perivascular...

BACKGROUND: Simultaneous pancreas-kidney transplantation (SPK) has become the treatment of choice for type 1 diabetes mellitus (T1DM) patients with chronic renal failure. Type 2 diabetes mellitus (T2DM), was once considered to be a contraindication for pancreas transplantation; however, it has been accepted as a new indication, under strict criteria. Although favorable results have increase the indication for T2DM in developed countries, there have been no reports of long-term results for this indication from Latin American centers...

The plant pathogen Pseudomonas syringae injects about 30 different virulence proteins, so-called effectors, via a type III secretion system into plant cells to promote disease. Although some of these effectors are known to suppress either pattern-triggered immunity (PTI) or effector-triggered immunity (ETI), the mode of action of most of them remains unknown. Here, we used transient expression in Nicotiana benthamiana , to test the abilities of type III effectors of Pseudomonas syringae pv. tomato ( Pto ) DC3000 and Pseudomonas syringae pv...
