abstract background: thyroglossal duct cysts (tdc) are the most common congenital neck masses arising from the expansion of the epithelial tract remnants occurring during embryogenic thyroid migration. about 7% of the population have thyroglossal duct remnants. clinical presentation is frequent in children, but adults can also present with thyroglossal duct cysts. thyroglossal duct cysts may ra...

Goeckerman's therapy (GT) of psoriasis is based on daily application of pharmacy grade coal tar on affected skin with subsequent exposure to UV light. The aim of this study was to evaluate the influence of Goeckerman's therapy of psoriasis on the levels of proangiogenic chemokines ENA-78 (CXCL5, Epithelial Cell Derived Neutrophil Attractant-78), GRO alpha (CXCL1, Growth-Related Oncogene), IL-8 ...

There are a number of different dwell positions and time optimisation options available in the Oncentra® Brachy (Elekta Brachytherapy Solutions, Veenendaal, The Netherlands) brachytherapy treatment planning system. The purpose of this case study was to compare graphical (GRO) and inverse planning by simulated annealing (IPSA) optimisation techniques for interstitial head and neck (HN) and prost...

Problems with executive function (EF) are considered a hallmark of Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum (ASD). However, little is known about the developmental pathway everyday EF in these two groups, whether groups follow similar or different course. In this longitudinal study, children adolescents ADHD (n = 84, Mage 11.6, SD 2.0), ASD 38, 12.0, 2.3), typically d...

This article presents the results of a systematic review different studies published in high-impact journals on development teaching digital competence (TDC) initial teacher training. The methodology study is based documentary research approach, with application literature covering period between 2009 and 2019 databases. sample made up 102 articles that are registered multidimensional analysis ...

We present a small-area second-order all-digital time-todigital converter (TDC) with two frequency shift oscillators (FSOs) comprising inverter chains and dynamic flipflops featuring low jitter. The proposed FSOs can maintain their phase states through continuous oscillation, unlike conventional gated ring oscillators (GROs) that are affected by transistor leakage. Our proposed FSOTDC is more r...

Mesenchymal stem/stromal cells (MSCs) are promising potential candidates for the treatment of immunological diseases because of their immunosuppressive functions. However, the molecular mechanisms that mediate MSCs' immunosuppressive activity remain elusive. In this article, we report for the first time, to our knowledge, that secreted growth-regulated oncogene (GRO) chemokines, specifically GR...

GRO J1655-40 is a transient black-hole candidate that has been shown to eject matter at apparently superluminal velocities. OSSE spectra measured during X-ray outbursts are consistent with a single power law up to 600 keV, with no evidence for a high-energy cutoo. Flaring behaviour of GRO J1655-40 has also been claimed to be detected up to 10 MeV during observations with the balloon-borne HIREG...

Non-muscle invasive bladder cancers (NMIBC) are typically treated by transurethral resection with intravesical chemotherapy. However, the post-therapeutic incidence of tumor recurrence and progression to muscle invasive disease is high, and the underlying mechanism(s) remains unknown. In this study, we observed that recurrent bladder cancer cells exhibit a mesenchymal phenotype, which is initia...

Thyroglossal duct cyst (TDC) is a congenital lesion which usually manifests as an enlarging painless neck mass in a child or young adult. We highlight an unusual presentation of TDC in an adult which developed after radiation therapy to the neck. We discuss the probable sequence of events and emphasize the need for radiologists, radiation oncologists and the surgeons to be aware of this entity ...
