Parkinson's disease (PD) is the most common movement disorder disease, and its pathological feature is the degenerative loss of dopaminergic neurons in the substantia nigra compacta (SNc). In this study, we investigated whether distinct stress conditions target F-box protein Fbw7β via converging mechanisms. Our results showed that the 6-hyroxydopamine (6-OHDA), which causes PD in animals' models, led to decreased stability of Fbw7β in DA neuronal SN4741 cells. Further experiments suggested that oxidized Fbw7β bound to heat-shock cognate protein 70 kDa, the key regulator for chaperone-mediated autophagy (CMA), at a higher affinity...

BACKGROUND: IgE-mediated cow's milk allergy (CMA) has been shown consistent in milder heated-milk tolerant and severe heated-milk reactant groups in patients older than two years. Little is known whether fermentation of milk gives rise to similar clinical phenotypes. We aimed to determine the influence of extensively heated and fermented cow's milk on the IgE-mediated and non-IgE-mediated CMA in children younger than two years. METHODS: Subjects followed with the diagnosis of IgE-mediated and non-IgE-mediated CMA for at least six months underwent unheated milk challenge...

OBJECTIVE Spinal metastases that recur after conventional palliative radiotherapy have historically been difficult to manage due to concerns of spinal cord toxicity in the retreatment setting. Spine stereotactic body radiation therapy (SBRT), also known as stereotactic radiosurgery, is emerging as an effective and safe means of delivering ablative doses to these recurrent tumors. The authors performed a systematic review of the literature to determine the clinical efficacy and safety of spine SBRT specific to previously irradiated spinal metastases...

The liver transplant patient was admitted to the hospital with hyperemic, granulomatous, ulcerated lesion in the anterior compartment of the right lower limb with report of local trauma. The agent Sporothrix schenckii was isolated from biopsy of the lesion and lymph nodes of the right lower limb. In this case, the treatment was difficult because the patient has severe pulmonary hypertension and took the following drugs: warfarin, sildenafil, and tacrolimus. These medicines interact with the antifungal, which made it difficult...

Most daily movements require some degree of collaboration between the upper limbs. The neural mechanisms are bimanual-condition specific and therefore should be different between different activities. In this study, we aimed to explore intraregional activation and interregional connectivity during bimanual movement by functional magnetic resonance imaging (fMRI). Ten right-handed, normal subjects were recruited. The neural correlates of unimanual (right side) and bimanual (in-phase and antiphase) upper limb movements were investigated...

REVIEW
Yvan Vandenplas
Introduction: The prevention and management of cow milk allergy (CMA) is still debated. Since CMA is much less frequent in breastfed infants, breastfeeding should be stimulated. Method: Literature was searched using databases to find original papers and reviews on this topic. Results: Hydrolysates with a clinical proof of efficacy are recommended in the prevention and treatment of CMA. However, not all meta-analyses conclude that hydrolysates do prevent CMA or other atopic manifestations such as atopic dermatitis...

Emerging studies have demonstrated that whole-genome sequencing (WGS) is an efficient tool for copy-number variants (CNV) detection, particularly in probe-poor regions, as compared to chromosomal microarray analysis (CMA). However, the cost of testing is beyond economical for routine usage and the lengthy turn-around time is not ideal for clinical implementation. In addition, the demand for computational resources also reduces the probability of clinical integration into each laboratory. Herein, a protocol providing CNV detection from low-pass, whole-genome sequencing (0...

BACKGROUND: The Society of Obstetricians and Gynecologists of Canada (SOGC) and the Canadian College of Medical Genetics (CCMG) published guidelines, in 2011, recommending replacement of karyotype with QF-PCR when prenatal testing is performed because of an increased risk of a common aneuploidy. STUDY OBJECTIVE: This study's objective is to perform a cost analysis following the implementation of QF-PCR as a stand-alone test. RESULTS: A total of 658 samples were received between April 1, 2014 and August 31, 2015: 576 amniocentesis samples and 82 CVS...

BACKGROUND: Cow milk (CM) allergy (CMA) affects up to 3% of the pediatric population and recent data suggest that only about 50% will outgrow by age 8. Oral immunotherapy (OIT) is a type of immune-modulating treatment that is able to induce desensitization to food allergens, to increase tolerance threshold, to reduce the risk of anaphylaxis, and to improve the patient's quality of life. The examination of the immunological changes observed during the establishment of food allergy (FA) desensitization in FA patients is a window into the pathogenesis of food allergy and food tolerance development...

Recent data have shown that the expression of lysosome-associated membrane protein type 2 A (LAMP2A), the key protein in the chaperone-mediated autophagy (CMA) pathway, is elevated in breast tumor tissues. However, the exact effects and mechanisms of CMA during breast cancer metastasis remain largely unknown. In this study, we found that the LAMP2A protein level was significantly elevated in human breast cancer tissues, particularly in metastatic carcinoma. The increased LAMP2A level was also positively correlated with the histologic grade of ductal breast cancer...

As health care moves to a value-based system, the need for team-based models of care becomes increasingly important to adequately address the growing number of clinical quality metrics required of health care providers. Finding ways to better engage certified medical assistants (CMAs) in the process allows providers to focus on more complex tasks while improving the efficiency of each office visit. Although the roles and responsibilities for CMAs across the specialties can vary widely, standardizing the work can be a helpful step in scaling best practices across an institution...

Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are neurogenetic disorders caused by loss of function of the imprinted genes at 15q11q13. A 5-7 Mb paternal/maternal deletion of chromosomal region 15q11.2q13 is the major genetic cause of PWS/AS, but in a small group of patients, the PWS/AS phenotype can result from maternal/paternal uniparental disomy (UPD) of chromosome 15. Various mechanisms leading to UPD include gametic complementation, trisomy rescue, and compensatory UPD, which can be inferred from the pattern of uniparental heterodisomy (heteroUPD) or uniparental isodisomy (isoUPD)...
