albicans such as adhesion, biofilm formation and filamentation properties. This review discusses the recent epidemiological burden of oral cancer and highlights the significance of the ECE1 gene and the ECE1 protein breakdown product, candidalysin in oral malignancy. The immunological and molecular mechanisms behind oral malignancy induced by inflammation and the role of the toxic fungal peptide candidalysin in oral carcinogenesis are explored. With increasing evidence associating C. albicans with oral carcinoma, identifying the possible fungal pathogenicity factors including the role of candidalysin can assist in efforts to understand the link between C. albicans infection and carcinogenesis, and pave the way for research into therapeutic potentials.

In some cases, the acquisition of additional genetic aberrations (clonal evolution [CE]) associated with clinical progression may occur during the disease. We analyzed a cohort of 469 MDS patients using a combination of molecular cytogenomic methods to identify cryptic aberrations and to assess their potential role in CE. We confirmed CE in 36 (8%) patients. The analysis of bone-marrow samples with a combination of cytogenomic methods at diagnosis and after CE identified 214 chromosomal aberrations. The early genetic changes in the diagnostic samples were frequently MDS specific (17 MDS-specific/57 early changes). Most progression-related aberrations identified after CE were not MDS specific (131 non-MDS-specific/155 progression-related changes). Copy number neutral loss of heterozygosity (CN-LOH) was detected in 19% of patients. MDS-specific CN-LOH (4q, 17p) was identified in three patients, and probably pathogenic homozygous mutations were found in TET2 (4q24) and TP53 (17p13.1) genes. We observed a statistically significant difference in overall survival (OS) between the groups of patients divided according to their diagnostic cytogenomic findings, with worse OS in the group with complex karyotypes (P = .021). A combination of cytogenomic methods allowed us to detect many cryptic genomic changes and identify genes and genomic regions that may represent therapeutic targets in patients with progressive MDS. © 2020 Wiley Periodicals, Inc.BACKGROUND Intralesional 5-fluorouracil (5-FU) in combination with triamcinolone acetonide (TAC) has been recommended as a promising alternative for keloids not responding to silicone-based products, cryotherapy or intralesional corticosteroids alone. Although numerous studies support the efficacy of this regime, there is a lack of objective data. OBJECTIVES In this study, we evaluate the therapeutic effect of four courses of intralesional 5-FU in combination with TAC (31) utilizing 3D analysis (PRIMOS®pico ), ultrasound and scar scales such as the Patient and Observer Scar Assessment Scales (POSAS) and the Dermatology Life Quality Index (DLQI). METHODS Twenty-five patients with keloids were treated using 5-FU and TAC every four weeks. Objective assessments were performed and the scar scales administered at baseline, as well as during consecutive visits at one- and 12-month follow-up (FU). Routine laboratory tests were performed at baseline and at one-month FU. RESULTS 3D PRIMOS and ultrasound measurements revealed highly significant and stable reductions in height (baseline mean score 4.0 ± 1.7 mm, one-month FU mean score 1.5 ± 0.8 mm, 12-month FU mean score 1.8 ± 0.9 mm, p = less then 0.0001), volume (baseline mean score 1,105 ± 911.5 mm3 , 1-month FU mean score 416.1 ± 218,1 mm3 , 12-month FU mean sore 431.2 ± 253.6 mm3 , p = less then 0.0001 respectively) and penetration depth of keloids (relative reduction between baseline and 12-month FU of 74.4%, p = less then 0.0001). The POSAS and DLQI scales confirmed significant objective and subjective improvements in scar appearance in all categories. The Life quality associated with keloid appearance improved from a "moderate effect" to a "small effect" throughout the course of the study. CONCLUSIONS Results of this study confirm the efficacy and safety of the combination of 5-FU and TAC in keloids. Treatments were well tolerated and demonstrated stable results at 12-month FU.

ALF is mostly caused by viral infections, drug intoxication, and metabolic diseases (MD) and can also have an indeterminate etiology. In this study, we aimed to evaluate the demographic and clinical characteristics and clinical outcomes of the patients that presented to our clinic with MD-associated ALF. METHODS The retrospective study reviewed age, gender, parental consanguinity, family history, presence of encephalopathy, laboratory parameters, and clinical outcomes of the patients that presented to our clinic between January 2009 and January 2019. Patients with MD-associated ALF were compared with patients detected with ALF associated with other etiologies. RESULTS The study included 39 patients (53.8% boys, mean age+SD; 6.13 ± 1.43 years). The total and direct bilirubin, INR, and ammoniac levels were significantly higher in patients with MD compared to the others (p less then 0.05). Moreover, the incidences of hypoglycemia, death of a sibling and/or a family history of liver disease were also higher in patients with MD compared to the others (p less then 0.05). On the other hand, ALT levels were significantly higher in patients with other etiologies. CONCLUSIONS MD should be kept in mind in patients with a history of parental consanguinity and a positive family history along with less increased ALT, increased bilirubin, INR, and ammoniac levels and hypoglycemia. As the number of these parameters increases, the chance of diagnosis increases. This article is protected by copyright.

This study used a population-based database to evaluate this relationship. METHODS Patients diagnosed with second primary lung cancer after a nonpulmonary malignancy were identified from the Surveillance, Epidemiology and End Results (SEER) registry from 2004 to 2015. Cumulative incidence function (CIF) and multivariable CIF regression analyses were performed to estimate the difference in disease-specific mortality (DSM) among different TNM stages. RESULTS Our cohort included 2687 patients from the SEER database. After CIF analysis, although rates of 1-year, 3-year, and 5-year DSM trended higher with increasing TNM stages, the DSM curves overlapped for many subcategories. In a multivariable regression analysis, hazards ratios (HRs) for subcategories of stage Ι demonstrated no significant difference compared with the reference stage ΙA1 ([ΙA2 HR = 1.120; 95% confidence interval [CI], 0.477-2.626]; [ΙA3 HR = 1.762; 95% CI, 0.752-4.126]; [ΙB HR = 2.003; 95% CI, 0.804-4.911]). The following HRs trended higher for increasing TNM stages but with overlapping CIs among adjacent stage groupings. Selleckchem AMG 487 CONCLUSION The 8th edition AJCC TNM staging system fails to provide accurate prognostic value for LCSPM. © 2020 Wiley Periodicals, Inc.RATIONALE An LC-MS/MS method has been developed and validated to determine levodopa, carbidopa, entacapone, and corresponding six related substance - levodopa impurity B, levodopa impurity C, methyldopa, methylcarbidopa, entacapone impurity C, and entacapone impurity A - in film-coated tablets at the first time. METHODS Chromatographic separation was achieved with a gradient elution by using a C18 column, a mobile phase containing 0.5% formic acid in water and 0.5% formic acid in methanol. The mobile phase flow rate was 0.5 mL min-1 . The UV detector was set at 280 nm and the triple quadrupole mass spectrometer was used in MRM mode. RESULTS The LOD and LOQ results were 1.3 and 3.94 ng mL-1 for levodopa impurity B; 5.26 and 15.9 ng mL-1 for levodopa impurity C; 0.833 and 2.53 ng mL-1 for methyldopa; 3.31 and 10.0 ng mL-1 for methylcarbidopa; 1.67 and 5.06 ng mL-1 for entacapone impurity C; and 0.61 and 1.86 ng mL-1 for entacapone impurity A. CONCLUSIONS The method was rapid, linear, accurate, and reproducible. The LC/MS/MS method that was developed to determine the related substances and assay of levodopa, carbidopa, and entacapone can be used to evaluate the quality of regular samples in the pharmaceutical industry. It can be also used to test the stability of samples. This article is protected by copyright.

The skin, as one of the organs involved, shows hyperextensibility, which makes it prone to trauma. In this context, it would seem logical for cutaneous synovial metaplasia, which is considered a form of repair, to be commonly found in cases of EDS. However, there are only two previously published cases of synovial metaplasia in EDS. We present a third case in a 56-year-old woman with painful redundant skin in both elbows and knees for whom a skin fold of the left elbow was removed to relieve her symptoms. The biopsy showed preservation of the elastic and collagen fibers. The main alteration was the evidence of dermal cystic spaces lined by fibrinoid rests with focal pseudopapillary projections. However, in some zones the cellular lining was preserved, and it was composed of vimentin-positive, fibroblast-like flat, elongated cells, as well as CD68-positive macrophages. No birefringent particles were found in an examination under polarized light. © 2020 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.The asymmetric polyethersulfone (PES-15 wt.%) mixed matrix membranes were prepared by incorporation of carbon molecular sieve (CMS) with varying concentrations (1, 3, 5 wt.%). Physico-chemical characterization of synthesized membranes was carried out using field emission scanning electron microscope, atomic force microscopy, contact angle, thermogravimetric analysis, zeta potential analyzer, porosity, and mean pore sizes. Performance analysis of synthesized mixed matrix membranes was carried out by varying the operating parameters such as pressure (2-10) bar, feed concentration (100 - 1000) mg. L-1 , cations type (Na+ , Ca2+ , Mg2+ , Sn2+ ). Effect of operating parameters and CMS concentration was investigated on pure water flux (PWF), permeate flux and rejection of membranes. It was found that mixed matrix membrane containing 15 wt% PES with 1 wt% CMS displayed the superior physicochemical characteristics in terms of hydrophilicity (37.9°), surface charge (-13.8 mV), mean pore diameter (6.04 nm) and thermal properties (Tg = 218.5 °C) as well as overall performance. E5C1 membrane showed 1.5 times higher PWF (75.5 L.m-2 .h-1 ) and incremented in rejection for all salts than the nascent membrane. This article is protected by copyright. All rights reserved.
