We investigated the role of copy number alterations to refine risk stratification in adult Philadelphia chromosome positive (Ph)+ ALL treated with tyrosine kinase inhibitors (TKI) and allogeneic stem cell transplantation (aSCT). 97 Ph+ ALL patients (median age 41 years, range 18-64 years) within the prospective multicenter GMALL studies 06/99 (n=8) and 07/2003 (n=89) were analysed. All patients received TKI and aSCT in first complete remission (CR1). Copy number analysis was performed with SNP arrays and validated by multiplex ligation-dependent probe amplification (MLPA)...

The feline model of Niemann-Pick disease, type C1 (NPC1) recapitulates the clinical, neuropathological, and biochemical abnormalities present in children with NPC1. The hallmarks of disease are the lysosomal storage of unesterified cholesterol and multiple sphingolipids in neurons, and the spatial and temporal distribution of Purkinje cell death. In feline NPC1 brain, microtubule-associated protein 1 light chain 3 (LC3) accumulations, indicating autophagosomes, were found within axons and presynaptic terminals...

In the human cerebellum, the crus I and crus II lobules (or the ansiform lobule), which are implicated in cognitive and visuomotor functions, are significantly expanded compared to other anterior and posterior lobules, which are involved mainly in somatosensorimotor function. In applying rodent models, it is essential to identify the lobules that are homologous to human crus I and crus II. Observation of the lobular structure in human, macaque, marmoset, rat, and mouse has indicated that human crus I and II are homologous to crus I in rodents (referred to as "ansiform area, AA")...

BACKGROUND: Robotic total pancreatectomy (TP) represents a minimally invasive approach to a major intra-abdominal operation. Its utility, technique, and outcomes are evolving. METHODS: In this video, we describe a systematic approach to a robotic total pancreatectomy performed for multifocal intraductal papillary mucinous neoplasm (IPMN). Additionally, we reviewed the National Cancer Database (NCDB) to examine the outcomes of robotic TP compared to laparoscopic and open TP between 2010 and 2014...

Dentatorubral-pallidoluysian atrophy (DRPLA) is an autosomal dominant spinocerebellar ataxia caused by CAG triplet expansion in atrophin 1 and is frequently associated with cerebral white matter lesions. To elucidate the clinical features of elderly onset DRPLA and the key radiological findings for differentiating DRPLA from physiological white matter lesions in healthy elderly subjects, we reviewed the clinical and magnetic resonance imaging (MRI) features of ten patients with elderly onset genetically confirmed DRPLA (> 60 years) and compared their MRI findings with those of age- and sex-matched ten healthy subjects with asymptomatic cerebral white matter lesions...

OBJECTIVES: Simultaneous pancreas and kidney transplant (SPK) is the most effective treatment for patients with type 1 diabetes mellitus and renal failure. However, the effect of ethnicity on SPK outcomes is not well understood. METHODS: We studied the influence of recipient ethnicity on SPK using the United Network for Organ Sharing database. A retrospective review of 20,196 SPK patients from 1989 to 2014 was performed. The recipients were divided into 4 groups: 15,833 whites (78...

The inferior olive (IO) is the sole source of the climbing fibers innervating the cerebellar cortex. We have previously shown both individual differences in the size and folding pattern of the principal nucleus (IOpr) in humans as well as in the expression of different proteins in IOpr neurons. This high degree of variability was not present in chimpanzee samples. The neurochemical differences might reflect static differences among individuals, but might also reflect age-related processes resulting in alterations of protein synthesis...

The alloys (GeTe)x(AgSbTe2)100-x, commonly known as TAGS-x, are among the best performing p-type thermoelectric materials for the composition range 80 ≤ x ≤ 90 and in the temperature range 200-500 °C. They adopt a rhombohedrally distorted rocksalt structure at room temperature and are reported to undergo a reversible phase transition to a cubic structure at ∼250 °C. However, we show that, for the optimal x = 85 composition (TAGS-85), both the structural and thermoelectric properties are highly sensitive to the initial synthesis method employed...

BACKGROUND: Mastectomy in the context of breast malignancy can have a profoundly negative impact on a woman's self-image, impairing personal, sexual and social relationships. The deep inferior epigastric perforator (DIEP) flap and implants are the two commonest reconstructive modalities that can potentially overcome this psychological trauma. The comparative data on clinical outcomes and costs of the two modalities is limited. We aim to synthesise the current evidence on DIEP versus implants to establish which is the superior technique for breast reconstruction, in terms of clinical outcomes and cost-effectiveness...

It is argued that the mesolimbic system has a more general function in processing all salient events, including and extending beyond rewards. Saliency was defined as an event that is unexpected due to its frequency of occurrence and elicits an attentional-behavioral switch. Using functional magnetic resonance imaging (fMRI), signals were measured in response to the modulation of salience of rewarding and nonrewarding events during a reward-based decision making task, the so called desire-reason dilemma paradigm (DRD)...

Absence epilepsy is characterized by the occurrence of generalized spike and wave discharges (GSWDs) in electrocorticographical (ECoG) recordings representing oscillatory activity in thalamocortical networks. The oscillatory nature of GSWDs has been shown to be reflected in the simple spike activity of cerebellar Purkinje cells and in the activity of their target neurons in the cerebellar nuclei, but it is unclear to what extent complex spike activity is implicated in generalized epilepsy. Purkinje cell complex spike firing is elicited by climbing fiber activation and reflects action potential firing in the inferior olive...

The cerebellum plays a big role in motor control and motor coordination in mammals, especially for limbs control. Therefore, many cerebellar models were proposed to be applied in the field of robotic arm control. However, some problems exist in the current cerebellar modeling approach, such as lack of the expression of bio-characteristics, limited learning ability et al. Therefore, a distributed cerebellar-inspired learning model was proposed to mimic the physiology and anatomy features of the cerebellum. Meanwhile, this model could learn to adjust the motor command according to the error information provided by the inferior olive to achieve control goal...

BACKGROUND CML presenting with a variant Philadelphia translocation, atypical BCR-ABL transcript, additional chromosomal aberrations, and evolving MDS is uncommon and therapeutically challenging. The prognostic significance of these genetic findings is uncertain, even as singular aberrations, with nearly no data on management and outcome when they coexist. MDS evolving during the course of CML may be either treatment-associated or an independently coexisting disease, and is generally considered to have an inferior prognosis...

BACKGROUND: Apathy can be defined as a reduction of goal-directed behavior and is a strong predictor for poor functional outcome in schizophrenia. However, no objective measure of apathy has been identified and assessment is limited to retrospective interview-based ratings. Here we aimed to identify more precise objective readouts of apathy for translational research and clinical practice. METHODS: We employed a combined approach including interview-based ratings of the two negative symptom factors apathy and diminished expression, actigraphy based measures of spontaneous motor activity and the evaluation of daily activities using ecological momentary assessment...

BACKGROUND: In various types of pulmonary research, pulmonary function testing (PFT) is performed to quantify the severity of lung disease. Induction of apnea and positive pressure ventilation are required for accurate PFT measurements in non-cooperative subjects. We compared two methods of apnea induction in infant olive baboons (Papio anubis). METHODS: Pulmonary function testing results were compared during apnea induced by hyperventilation (CO2 washout) vs. intravenous propofol (1 dose 10 mg/kg)...

INTRODUCTION: A Collis gastroplasty combined with a Nissen fundoplication is commonly used when a shortened esophagus is encountered. An alternative combines intra-abdominal fixation of the gastroesophageal junction via a Hill gastropexy with a Nissen fundoplication to maintain length and avoid juxtaposing acid-secreting tissue against the diseased esophagus. METHODS: A retrospective case-controlled analysis of 106 consecutive patients with short esophagus undergoing Hill-Nissen (HN) or Collis-Nissen (CN) was compared to a cohort of 105 matched patients without short esophagus undergoing primary Nissen fundoplication (NF)...

Sudden infant death syndrome (SIDS) involves failure of arousal to potentially life threatening events, including hypoxia, during sleep. While neuronal dysfunction and abnormalities in neurotransmitter systems within the medulla oblongata have been implicated, the specific pathways associated with autonomic and cardiorespiratory failure are unknown. The neuropeptide substance P (SP) and its tachykinin neurokinin-1 receptor (NK1R) have been shown to play an integral role in the modulation of homeostatic function in the medulla, including regulation of respiratory rhythm generation, integration of cardiovascular control, and modulation of the baroreceptor reflex and mediation of the chemoreceptor reflex in response to hypoxia...

Pressure ulcers represent a major current health problem and cause an important economic impact on the healthcare system. Most studies on the prevention of pressure ulcers have been carried out in hospital contexts, with respect to the use of hyperoxygenated fatty acids (HOFA), and to date no studies have specifically examined the use of olive oil-based treatments. AIM: To evaluate the cost of using extra virgin olive oil, rather than HOFA, in the prevention of pressure ulcers among persons with impaired mobility and receiving home care...

In stimulus-selective stop-signal tasks, the salient stop signal needs attentional processing before genuine response inhibition is completed. Differential prefrontal involvement in attentional capture and response inhibition has been linked to the right inferior frontal junction (IFJ) and ventrolateral prefrontal cortex (VLPFC), respectively. Recently, it has been suggested that stimulus-selective stopping may be accomplished by the following different strategies: individuals may selectively inhibit their response only upon detecting a stop signal (independent discriminate then stop strategy) or unselectively whenever detecting a stop or attentional capture signal (stop then discriminate strategy)...
