Nowadays, no suitable animal model exists to assess long-term disabilities after cerebral ischemia. The aim of this study was to compare long-term behavioral and histological differences between two common mouse strains (129S2/SvPasCrl and C57BL6H) after 30 minutes of middle cerebral artery occlusion (MCAo). Sensorimotor assessments were conducted at one and at three weeks post-surgery using accelerated Rotarod and open-field locomotion. Long-term behavioral testing began four weeks after MCAo using operant conditioning in a progressive fixed-ratio (FR) schedule. Experiments ended with volumetric determination of the infarcted area using NeuN immunostaining. Although no effect of ischemia was detected in 129S2 mice using these tests, in C57 mice, results showed obvious short-term motor and locomotor deficits. Furthermore, subtle but persistent disturbances of endurance and executive functioning were recorded by the progressive schedule tests but not highlighted by sensorimotor tests. Ischemic lesion extended to the dorsolateral part of the striatum in both strains and recurrent cortical damages were also observed in C57 mice. All those results are in accordance with inherent morphological and behavioral features of each strain. Since the motor cortex is spared by 30 minutes MCAo, functional disabilities could be related to striatal damages. In conclusion, C57BL/6H mouse strain, by offering an acceptable survival rate and enough sensitivity to MCAo, seems to be a mouse strain suitable to evaluate long-term deficits and possible functional recovery after cerebral ischemia.

Objectives – The aim of this study is to describe the prevalence of postoperative laminitis in colic cases and to determine if low-molecular-weight heparin (LMWH) is effective in preventing this complication. Design – Retrospective clinical study. Animals – Client-owned horses. Interventions – SC administration of enoxaparin during the postoperative period. Measurements and Main Results – Medical records of 360 horses undergoing surgery for colic and surviving at least 3 days were evaluated. Fifty-six horses admitted before 1995 did not receive LMWH (control group) and 304 admitted after 1995 received LMWH as a prophylaxis for laminitis (treatment group). Three grades of severity were defined for laminitis. Prevalence and severity of laminitis were compared between the 2 groups. Several parameters recorded on admission (sex, age, breed, site and nature of the disease, heart rate, PCV, gravity score, and shock score) and the administration of LMWH were tested as risk factors in the development of laminitis in a logistic regression procedure. Prevalence and grade of laminitis were significantly lower in the treatment group. Only the absence of LMWH was recognized as a significant risk factor in the logistic regression model. Conclusions – The administration of LMWH appears to be effective in the prophylaxis of laminitis following colic surgery and may be useful in the postoperative management of these horses. [less ▲]

Mouse B16 melanoma cells (B16, parental line) and two derived clones either pigmented (B16P) or non pigmented (B16NP) were cultured as monolayers (2D) or on agar, as aggregates (3D). The productions of gelatinases A and B (72 kDa and 92 kDa type IV collagenases) and their inhibitors (TIMP1 and TIMP2), plasminogen activators (PAs) and plasminogen activator inhibitors (PAI) were investigated. The B16 cell lines did not secrete any gelatinase, but they secreted TIMP2, tissue-type (t-PA), urokinase-type (u-PA) plasminogen activators and PAI-1 like activities. High levels of PAI activity were determined in conditioned media and cellular extracts of B16NP, which could account for the lower tumorigenic potential of these cells. In 3D cultures, the cellular extracts of the three cell lines contained essentially u-PA activity. This activity could contribute to the greater tumorigenic and invasive capacities of B16, B16P and B16NP when cultured in 3D. [less ▲]

Matrix-Assisted Laser Desorption/Ionization time-of-flight (MALDI-TOF) mass spectrometry is evaluated as an elucidation tool for structural features and molecular weights estimation of some extracted herbaceous lignins. Optimization of analysis conditions, using a typical organic matrix, namely CHCA (alpha-cyano-4-hydroxycinnamic acid), in combination with alpha-cyclodextrine, allows efficient ionization of poorly soluble lignin materials and suppression of matrix-related ions background. Analysis of low-mass fragments ions (m/z 100-600) in the positive ion mode offers a “fingerprint” of starting lignins that could be a fine strategy to qualitatively identify principal interunit linkages between phenylpropanoid units. The molecular weights of lignins are estimated using size exclusion chromatography and compared to MALDI-TOF-MS profiles. Miscanthus (Miscanthus x giganteus) and Switchgrass (Panicum Virgatum L.) lignins, recovered after a formic acid/acetic acid/water process or aqueous ammonia soaking, are selected as benchmarks for this study.

The paper addresses the problem of decentralized optimization for a power system partitioned into several areas controlled by different transmission system operators (TSOs). The optimization variables are the settings for taps, generators’ voltages and compensators’, and the objective function is either based on the minimization of reactive power support, the minimization of active power losses, or a combination of both criteria. We suppose that each TSO assumes an external network equivalent for its neighboring areas and optimizes without concern for the neighboring systems’ objectives its own optimization function. We study, in the context where every TSO adopts the same type of objective function, the performance of an iterative scheme, where every TSO refreshes at each iteration the parameters of its external network equivalents depending on its past internal observations, solves its local optimization problem, and then, applies its “optimal actions” to the power system. In the context of voltage optimization, we find out that this decentralized control scheme can converge to nearly optimal global performance for relatively simple equivalents and simple procedures for fitting their parameters.

New radiocarbon and chlorofluorocarbon-11 data from the World Ocean Circulation Experiment are used to assess a suite of 19 ocean carbon cycle models. We use the distributions and inventories of these tracers as quantitative metrics of model skill and find that only about a quarter of the suite is consistent with the new data-based metrics. This should serve as a warning bell to the larger community that not all is well with current generation of ocean carbon cycle models. At the same time, this highlights the danger in simply using the available models to represent the state-of-the-art modeling without considering the credibility of each model. [less ▲]
