Micromorphological factors on Alyssum nezaketiae Aytaç & H. Duman (Brassicaceae), endemic in order to gypsum environments through Bulgaria: An electron microscopic research.
EMT is a cellular process characterized by the loss of cell polarity, reorganization of the cytoskeleton, and signaling reprogramming (upregulation of mesenchymal genes and downregulation of epithelial genes). Previously, we and others have shown the effects of mitotic kinases like Nek2 and Mps1 (TTK) on EMT. In this review, we focus on Aurora A, Aurora B, Bub1, and highly expressed in cancer (Hec1) as novel targets for therapeutic interventions in breast cancer and their effects on EMT. We highlight the established relationships and interactions of these and other mitotic kinases, clinical trial studies involving mitotic kinases, and the importance that represents to develop drugs against these proteins as potential targets in the primary care therapy for TNBC.Assessment of respiratory mechanics extends from basic research and animal modeling to clinical applications in humans. However, to employ the applications in human models, it is desirable and sometimes mandatory to study non-human animals first. To acquire further precise and controlled signals and parameters, the animals studied must be further distant from their spontaneous ventilation. The majority of respiratory mechanics studies use positive pressure ventilation to model the respiratory system. In this scenario, a few drug categories become relevant anesthetics, muscle blockers, bronchoconstrictors, and bronchodilators. Hence, the main objective of this study is to briefly review and discuss each drug category, and the impact of a drug on the assessment of respiratory mechanics. Before and during the positive pressure ventilation, the experimental animal must be appropriately sedated and anesthetized. H-151 cost The sedation will lower the pain and distress of the studied animal and the plane of anesthesia will pr the mathematical modeling of the respiratory system, systemic conditions, and respiratory mechanics outcomes.Aim Given a lack of standard of care treatment for recurrent/metastatic nasopharyngeal carcinoma (R/M NPC), we assessed treatment patterns and overall survival in the real-world setting. Materials & methods A retrospective chart review was conducted in patients who initiated first-line systemic therapy in Taiwan and South Korea between January 2012 and June 2013 with follow-up through December 2015. Results Among 154 R/M NPC patients, all patients in Taiwan (n = 104) had distant metastases, whereas in South Korea (n = 50) 42% had distant metastases. Patients with distant metastases generally received systemic therapy only (71%) for whom median overall survival was 23 months (95% CI 18-32). Conclusion Prognosis in R/M NPC with distant metastases remains poor, underscoring the need for more efficacious treatments.
Animal experimental model.

To study the clinical behavior and histological changes in the spinal cord, nerve roots and perivertebral muscles of the spine after induced leakage of polymethylmethacrylate (PMMA) loaded with antiblastic drugs during vertebroplasty in an animal model of pigs.

We performed vertebroplasty on 25 pigs. The animals were divided into 3 groups vertebroplasty with PMMA alone (control group), vertebroplasty with PMMA loaded with methotrexate (MTX) and vertebroplasty with PMMA loaded with cisplatin (CYS). At 2 vertebral levels, epidural and prevertebral, massive cement leaks were induced. Animals were evaluated daily. Two weeks later, the pigs were sacrificed, and the tissues that came in contact with the cement were analyzed.

The clinical results for each of the groups were reported. The control group had no clinical alterations. In the MTX group, 2 pigs died before 1 week due to pneumonitis. In the CYS group, 4 animals had motor impairment, and 3 of the 4 had paraplegia. The histological results were as follows the control and MTX groups showed synovial metaplasia, inflammatory reaction, crystal deposits, and giant cell reaction in the dura mater and muscle and all the animals in the CYS group had spinal cord and muscular necrosis.

Massive cement leak after vertebroplasty with PMMA loaded with cisplatin is extremely toxic to the spinal cord and muscles around the spine. Therefore, its use cannot be recommended for the treatment of vertebral metastases. Using PMMA loaded with methotrexate seems to be a safe procedure, but further research is needed.

Retrospective cohort study.

Despite pyogenic spondylodiscitis potentially conferring significant morbidity, there is no consensus on optimal treatment. The Brighton Spondylodiscitis Score (BSDS) was developed to identify patients who would likely fail conservative management and therefore benefit from earlier surgical intervention. In this study, we attempt external validation of the BSDS.

We carried out a retrospective review of all patients treated at our institution, 2010-2016, for pyogenic spondylodiscitis. 91 met inclusion criteria and 40 progressed to require surgical intervention. The BSDS was calculated for each patient allowing stratification into low-, moderate- and high-risk groups. Calibration and discrimination was assessed with ROC curve analysis and calibration plot.

Area under the curve (AUC) was 0.469 (0.22-0.71) in our external validation, compared with AUC 0.83 and 0.71 (CI 0.50-0.88) in the original study and test populations respectively. Only 60% of patients in the high-risk groun other health care systems that may comprise significantly different patient and pathogen characteristics.Aim To assess the impact of sociodemographic factors and beliefs about medicines on the uptake of pharmacogenomic testing in older adults in a public healthcare system. Materials & methods Data are based on a sample of 347 primary care older adults. Results Most respondents (90%) were willing to provide a saliva sample and 47% were willing to pay for it. Increased age (odds ratio 0.91; p = 0.04) and negative beliefs about the harmfulness of medicines (odds ratio 0.68; p = 0.02) were associated with a decreased willingness to provide a sample. Lower education (less than university, odds ratio 0.54; p = 0.04) was associated with a decreased willingness to pay. Conclusion Education and beliefs about medicines are important factors in the acceptability of pharmacogenomic testing in older adults.
To report a case of a patient with NF1 presenting with ocular findings of AV malformation, multiple retinal hemorrhages, and neovascular glaucoma in the absence of retinal ischemia.

Review of the medical record was conducted in accordance with the local IRBt.

A 60-year-old female patient with diagnosis of Neurofibromatosis type1 (NF1) and sudden decrease of vision in her left eye was found to have rubeosis iridis and high intraocular pressure (IOP). On fundus exam multiple corkscrew retinal vessels and retinal hemorrhages were present in her left eye. On Optical Coherence Tomography (OCT) the foveal hemorrhages appeared as outer layer hyperreflective retinal infiltrates whereas in the parafoveal area the hyperreflectivity was present between the RPE and neurosensory retina. Fluorescein Angiogram (FA) showed normal perfusion and no areas of leakage or ischemia. Treatment with anti-angiogenics in a timely manner correlated with a good visual outcome.

We present a unique patient with NF1, rubeosis iridis, high IOP, and macular hemorrhages from multiple corkscrew retinal vessels in a well perfused retina, who underwent treatment with a single dose of intravitreal Bevacizumab and had an excellent response.

To present a rare and novel association of Ocular Cicatricial Pemphigoid, Sjögren's Syndrome, and Hashimoto's Thyroiditis as a Multiple Autoimmune Syndrome.

A 43-year-old Colombian female, presented with corneal ulcers, associated with trichiasis. At the ophthalmological examination forniceal shortening OU and symblepharon OD was found. Conjunctival biopsy was performed, evidencing linear deposition of IgG and IgA antibodies along the basement membrane of the conjunctiva, confirming Ocular Cicatricial Pemphigoid diagnosis. After 12 years, the patient presented constitutional symptoms, xerostomia, and worsening of xerophthalmia. Laboratory tests showed positive Anti-TG, Anti-TPO, Anti-Ro, and Anti-La antibodies, and salivary gland biopsy was consistent with Sjögren's Syndrome. Due to these findings, Hashimoto's Thyroiditis and Sjögren's Syndrome were diagnosed, defining a Multiple Autoimmune Syndrome.

A novel association of Multiple Autoimmune Syndrome is presented in this case. Ophthalmologists and other specialists involved in the evaluation and treatment of patients with autoimmune diseases, should be aware of this clinical presentation. A multidisciplinary approach in this condition is important for optimum treatment instauration and follow-up, in order to prevent complications.

The aim of this controlled follow-up study was to compare the need for revision surgery, long-term efficacy, and satisfaction in chronic rhinosinusitis patients who had undergone maxillary sinus operation with either balloon sinuplasty or traditional endoscopic sinus surgery (ESS) technique.

Thirty-nine ESS patients and 36 balloon patients of our previously described cohort, who had been primarily operated in 2008 to 2010, were contacted by phone. Symptoms, satisfaction, and need for revision surgery were asked. In addition, we collected data of patients who had undergone primary maxillary sinus balloon sinuplasty in the Helsinki University Hospital during the years 2005 to 2019. As a control group, we collected data of patients who had undergone primary maxillary sinus ESS at 3 Finnish University Hospitals, and 1 Central Hospital in years 2005, 2008, and 2011.

Altogether, 77 balloon patients and 82 ESS patients were included. The mean follow-up time was 5.3 years in balloon group and 9.8 years in ESS group. Revision surgery was performed on 17 balloon patients and 6 ESS patients. In the survival analysis, the balloon sinuplasty associated significantly with a higher risk of revision surgery compared to ESS. According to the phone interviews, 82% of ESS patients and 75% of balloon patients were very satisfied with the primary operation.

Although the patient groups expressed equal satisfaction and change in symptoms after the operations, the need for revision surgery was higher after balloon sinuplasty than after ESS. This should be emphasized when counselling patients regarding surgical options.
