Ning Wang, Yaxian Wang, Youlong Xie, Huayan Wang
The transcription factor Otx2 acts as a negative switch in the regulation of transition from naive to primed pluripotency in mouse pluripotent stem cells. However, the molecular features and function of porcine OTX2 have not been well elucidated in porcine-induced pluripotent stem cells (piPSCs). By studying high-throughput transcriptome sequencing and interfering endogenous OTX2 expression, we demonstrate that OTX2 is able to downgrade the self-renewal of piPSCs. OTX2 is highly expressed in porcine brain, reproductive tissues, and preimplantation embryos, but is undetectable in fibroblasts and most somatic tissues...

BACKGROUND/PURPOSE: Approximately half of patients with systemic lupus erythematosus (SLE) develop lupus nephritis (LN), a major cause of morbidity and early mortality in that disease. Prolonged renal inflammation is associated with irreversible kidney damage which confers a 30% risk of end stage renal disease (ESRD), making early, aggressive treatment mandatory. Failure to achieve therapeutic response or recurrence of renal flare often prompts repeat biopsy. However, the role of repeat biopsy in determining long-term renal prognosis remains controversial...

Li Qi, Yanqing Sun, Peter B Gilbert
This article investigates a generalized semiparametric varying-coefficient model for longitudinal data that can flexibly model three types of covariate effects: time-constant effects, time-varying effects, and covariate-varying effects. Different link functions can be selected to provide a rich family of models for longitudinal data. The model assumes that the time-varying effects are unspecified functions of time and the covariate-varying effects are parametric functions of an exposure variable specified up to a finite number of unknown parameters...

Catheter ablation for rhythm control in atrial fibrillation has been recognized as an established treatment. Patients with atrial fibrillation suffer from an increased risk from thromboembolic events. Long-term stroke risk and mortality has been shown to be reduced after catheter ablation, still the procedure per se is associated with an additive peri-procedural thromboembolic risk. Maintenance of the thrombotic - bleeding equilibrium in such patients during interventional procedures is compelling. Lack of data from randomized studies along with the recent introduction of novel oral anticoagulants in clinical practice has resulted in a wide variance of antithrombotic treatment approaches...

Considerable evidence suggests that human category learning recruits multiple memory systems. A popular assumption is that procedural memory is used to form stimulus-to-response mappings, whereas declarative memory is used to form and test explicit rules about category membership. The multiple systems framework has been successful in motivating and accounting for a broad array of empirical observations over the past 20 years. Even so, only a couple of studies have examined how the different categorization systems interact...

Obesity is one of the most important public health conditions worldwide. Bariatric surgery for severe obesity is an effective treatment that results in the improvement and remission of many obesity-related comorbidities, as well as providing sustained weight loss and improvement in quality of life. Contemporary bariatric operations include Roux-en-Y gastric bypass, sleeve gastrectomy, adjustable gastric band and the duodenal switch. The vast majority of these procedures are now performed using laparoscopic technique, the main advantages of which include rapid recovery, the reduction of postoperative pain and the reduction of wound-related complications, compared with open surgery...

BACKGROUND: Obtaining accurate estimates of biological or enzymatic reaction rates is critical in understanding the design principles of a network and how biological processes can be experimentally manipulated on demand. In many cases experimental limitations mean that some enzymatic rates cannot be measured directly, requiring mathematical algorithms to estimate them. Here, we describe a methodology that calculates rates at which light-regulated proteins switch between conformational states...

BACKGROUND: Interferons-beta (IFNs-beta) and glatiramer acetate (GA) were the first two disease-modifying therapies (DMTs) approved 20 years ago for the treatment of multiple sclerosis (MS). DMTs' prescription rates as first or switching therapies and their costs have both increased substantially over the past decade. As more DMTs become available, the choice of a specific DMT should reflect the risk/benefit profile, as well as the impact on quality of life. As MS cohorts enrolled in different studies can vary significantly, head-to-head trials are considered the best approach for gaining objective reliable data when two different drugs are compared...

Humidity detection, and the quest for low-cost facile humidity-sensitive indicator materials is of great interest for many fields, including semi-conductor processing, food transport and storage, and pharmaceuticals. Ideal humidity-detection materials for a these applications might be based on simple clear optical readout with no power supply, i.e.: a clear color change observed by the naked eye of any untrained observer, since it doesn't require any extra instrumentation or interpretation. Here, the introduction of a synthesis-free one-step procedure, based on physical mixing of easily available commercial materials, for producing a humidity memory material which can be easily painted onto a wide variety of surfaces and undergoes a remarkable color change (approximately 100 nm blue-shift of λMAX ) upon exposure to various thresholds of levels of ambient humidity is reported...

The enhanced sample collection capability of a heart-cutting three-dimensional GC-prep system is reported. In its original configuration, a highly pure component can be usually collected after the last (3D) column outlet by means of a dedicated preparative station. The latter is located after the last chromatographic column, and this poses the requirement for multiple heart cuts even for those components showing satisfactory degree of purity after the first (or second) separation dimension. The feasibility to collect pure components after each chromatographic dimension is here described, employing a three-dimension MDGC system equipped with high-temperature valves, located inside the first and second GC ovens, with the aim to improve the productivity of the collection procedure...

Residual switch costs are deficits in task-switching performance that occur despite considerable time to prepare for a task switch. In the present study, the author investigated whether increased phasic alertness modulates residual switch costs. In 2 experiments involving the task-cuing procedure, subjects performed numerical categorization tasks on target digits, with and without an alerting stimulus presented shortly before the target (alert and no-alert trials, respectively). Switch costs were obtained that decreased with a longer cue-target interval, indicating subjects engaged in preparation, but large residual switch costs remained...

Bilateral cleft lip repairs can result in various secondary deformities. One more commonly seen deformity, the whistle deformity, is characterized by a reduced or absent tubercle, orbicularis muscle diastasis, and abnormalities of the philtrum with notched appearance of cupid's bow. Various techniques have been described to address these problems. One common procedure is the lip-switch flap originally described by Abbe in 1898, which has been modified by various surgeons. In these procedures, lower lip vermilion, mucosa, orbicularis, and lip skin are transposed to the upper lip on a pedicle that is later divided...

Procedures for selective installation of acyl, silyl ether and para-methoxybenzyl (PMB) ether groups to glycoside substrates have been developed, employing phenylboronic esters as protected intermediates. The sequence of boronic ester formation, functionalization and deprotection can be accomplished with only a single purification step, and the boronic acid component can be recovered and reused after deprotection. Key advances include the identification of reaction conditions for installation of PMB groups in the presence of boronic esters, and the use of the 'phase switching' protocol developed by Hall and co-workers as an efficient method for boronic ester cleavage...
