Oral Manifestations of Wolf-Hirschhorn Syndrome: Genotype-Phenotype Correlation Analysis

2020

Background: Wolf-Hirschhorn syndrome (WHS) is a rare disease caused by deletion in the distal moiety of the short arm of chromosome 4. The objectives of this study were to report the most representative oral findings of WHS, relate them with other clinical characteristics of the disease, and establish possible phenotype-genotype correlation. Methods: The study was conducted at 6 reference centers distributed throughout Spain during 2018&ndash

Discrimination in the sharing economy: evidence from a Hungarian field experiment

2018

Findings from our pilot research project which focused on providing car sharing services to young people with different ethnic/racial background showed discrimination against certain ethnic groups. The research was based on a controlled field experimental design to examine the chances of rides being offered to racially different testers. The experimental variables were both race and gender. Creating altogether 8 profiles enabled us to test the interaction between these two experimental stimulus. The small-scale research (total N=160) was implemented in Hungary, in summer 2017 by interns of TARKI, Hungarian Social Research Centre. The forthcoming article shows evidence of ethnic/racial dispr…

Degenerative and regenerative processes involved in midgut pseudotumor formation in the stick insect (Carausius morosus)

2009

Spontaneous and experimentally induced pseudotumor formation in Carausius morosus impairs the midgut tissue homeostasis. Spontaneous pseudotumor formation begins by the break down of a single or a small group of columnar cells (CCs) and is followed by the degeneration of neighboring CCs. There are not only marked similarities but also decisive differences between normal dying CCs in healthy specimens and the degeneration of CCs leading to pseudotumors: in both cases, the apical cell parts with the nucleus are extruded into the midgut lumen, but only during of pseudotumor formation an "amorphous substance" originates from the basal parts of the CCs. Hemocytes are attracted to this substance …

Midgut pseudotumors and the maintenance of tissue homeostasis: studies on aging and manipulated stick insects.

2009

Stick insects (Carausius morosus) develop pseudotumors in aging adults. Pseudotumor formation starts at the M2 midgut region where an accumulation of stomatogastric nerve terminals is observed. Pseudotumors arise from dying columnar cells whose basal parts form an “amorphous substance” at the basement membrane whereas the apical parts, including the nucleus, are expelled into the gut lumen. The “amorphous substance” is ensheathed by hemocytes. These nodules, which do not melanize, characterize the phenotype of the pseudotumors. With age, cell death and pseudotumor infestation increases. It is shown that the maintenance of midgut tissue homoeostasis is disturbed and becomes more serious with…

Drying enhances immunoactivity of spent brewer's yeast cell wall β-D-glucans.

2015

Due to immunological activity, microbial cell wall polysaccharides are defined as 'biological response modifiers' (BRM). Cell walls of spent brewer's yeast also have some BRM activity. However, up to date there is no consensus on the use of spent brewer's yeast D-glucan as specific BRM in humans or animals. The aim of this paper is to demonstrate the potential of spent brewer's yeast β-D-glucans as BRM, and drying as an efficient pretreatment to increase β-D-glucan's immunogenic activity. Our results revealed that drying does not change spent brewer's yeast biomass carbohydrate content as well as the chemical structure of purified β-D-glucan. However, drying increased purified β-D-glucan TN…

Pulmonary haemodynamics in obstructive sleep apnoea.

1995

In patients with obstructive sleep apnoea syndrome (OSAS), pulmonary haemodynamics can show both transient perturbations during sleep and permanent alterations. During sleep, repeated fluctuations in pulmonary artery pressure and pulmonary wedge pressure, coincident with apnoeas, can be observed. Calculation of transmural pressure values is preferable to intravascular pressures in OSAS, due to the marked swings in intrathoracic pressure associated with obstructive apnoeas. Pulmonary artery pressure may progressively increase during sleep, particularly in close sequences of highly desaturating apnoeas. Apnoea-induced hypoxia appears as the most important determinant of this pulmonary artery …

Metástasis en hueso maxilar superior de adenocarcinoma de esófago: presentación de un caso clínico

2005

Las metástasis en cavidad oral son lesiones raras que representan aproximadamente el 1% de todas las neoplasias malignas de cavidad oral. Las metástasis orales se localizan en un 80-90% en mandíbula, siendo mas raras en maxilar superior. Las metástasis en tejidos blandos de boca son raras, y es encía donde con mayor frecuencia se localizan las metástasis en tejidos blandos en boca. Los tumores primarios que metastatizan a boca son los más frecuentes pulmón, mama y riñón. Las metástasis en cavidad oral es como consecuencia de una diseminación a distancia de la enfermedad e indica un mal pronóstico, con una supervivencia corta. Aquí presentamos un caso clínico de un paciente diagnosticado de …

All-trans retinoic acid restores gap junctional intercellular communication between oral cancer cells with upregulation of Cx32 and Cx43 expressions …

2012

Objective: All-trans retinoic acid (ATRA) has been demonstrated to inhibit tumor growth by restoration of gap junctional intercellular communication (GJIC) via upregulation of connexin (Cx) expression in some solid tumors. However, the relationship between ATRA and GJIC remains unclear in oral squamous cell carcinoma (OSCC). The aim of this study was to investigate the effect of ATRA on the GJIC function of OSCC. Study design: We measured the effects of ATRA on the viability and cell cycle distribution of SCC9 and Tca8113 OSCC cells. The GJIC function was observed using the scrape-loading dye transfer technique, and the mRNA and protein levels of Cx32 and Cx43 were detected by qRT-PCR, West…
