Resistance of Resin-Bonded Ceramic Endocrowns of Different Intracoronal Depths.

Purpose: This in-vitro study was conducted to assess the fracture resistance of resin-bonded ceramic endocrowns with different designs at varying intracoronal depths.

Materials And Methods: Forty-eight (n = 48) extracted mandibular first molar teeth were randomly divided into four groups (n = 12). In the control group, the specimens remained untreated.

Perceived stress among dental students and the role of parental influence in career decision-making.

Objectives: The current study aimed to assess perceived stress levels among dental students at Riyadh, Saudi Arabia, and to explore the influence of parental roles in their decision to pursue dentistry as a potential source of social stress.

Methods: This cross-sectional study employed the validated Dental Environmental Stress (DES) Scale to evaluate perceived stress, and incorporated additional questions to fulfill the research aim. We approached all undergraduate dental students at King Saud University, both male and female, across all academic years, using online channels (such as emails, WhatsApp, Twitter, etc.

Regular swimming exercise improves metabolic syndrome risk factors: a quasi-experimental study.

Background: In the past few decades, swimming became one of the most important physical activities within the health system and is considered a practical nonpharmacological approach to managing of type 2 diabetes (T2DM), hyperlipidemia, hypertension (HTN), and obesity. The current study aimed to assess the effect of long-term swimming sessions on glycemic and lipidemic parameters, hemodynamic responses, body fat percent, and body mass index for patients with metabolic risk factors from Palestine.

Methods: Forty participants from both genders with T2DM and HTN (aged 52.

Maximum mouth opening and its correlation with gender, age, height, weight, body mass index, and temporomandibular joint disorders in a Saudi population.

: To investigate maximum mouth opening (MMO) and its correlation with gender, age, height, weight, Body Mass Index, and temporomandibular joint disorders in a Saudi population.: This is an observational cross-sectional study of 222 Saudi patients (46% male and 54% female). Patients were clinically examined, and files were accessed to record data.

Sézary syndrome is a unique cutaneous T-cell lymphoma as identified by an expanded gene signature including diagnostic marker molecules CDO1 and DNM3.

Sezary syndrome (SS) is a rare, aggressive CD4+ cutaneous T-cell lymphoma (CTCL); molecular traits differentiating SS from nonleukemic mycosis fungoides (MF) and from inflammatory skin diseases (ID) are not sufficiently characterized. Peripheral blood mononuclear cells (PBMC) of 10 SS patients and 10 healthy donors (HD) were screened by Affymetrix U133Plus2.0 chips for differential gene expression.

Overexpression of c-myb in leukaemic and non-leukaemic variants of cutaneous T-cell lymphoma.

Background: The c-myb oncogene is a transcription factor that regulates proliferation, differentiation and apoptosis of haematopoietic cells and activated T cells by binding to promoter sequences of such genes as c-myc or bcl-2 that are expressed in cutaneous T-cell lymphoma (CTCL).

Objective: Our study was performed in order to evaluate c-myb expression as a quantitative parameter for differential diagnosis in leukaemic and non-leukaemic variants of CTCL.

Methods: c-myb expression was analysed in lesional skin and in the peripheral blood of 21 patients with mycosis fungoides (MF), 15 patients with Sézary syndrome (SS) and 15 patients with inflammatory skin diseases using immunohistochemistry and semiquantitative as well as quantitative RT-PCR.

Jessner's lymphocytic infiltration of the skin: a CD8+ polyclonal reactive skin condition.

Background: Jessner's lymphocytic infiltration of the skin (JLIS) is a clinically and histologically distinct disease entity. Conflicting results have been reported concerning its differentiation from cutaneous lupus erythematosus and polymorphous light eruption, its relationship to palpable migratory arciform erythema and its classification as a B-cell or a CD4+ T-cell lymphoproliferative disease.

Objective: Our study was performed in order to re-evaluate JLIS clinically and by immunohistochemical and molecular analyses.

Expression of inducible nitric oxide synthase in skin lesions of patients with american cutaneous leishmaniasis.

Cytokine-inducible (or type 2) nitric oxide synthase (iNOS) is indispensable for the resolution of Leishmania major or Leishmania donovani infections in mice. In contrast, little is known about the expression and function of iNOS in human leishmaniasis. Here, we show by immunohistological analysis of skin biopsies from Mexican patients with local (LCL) or diffuse (DCL) cutaneous leishmaniasis that the expression of iNOS was most prominent in LCL lesions with small numbers of parasites whereas lesions with a high parasite burden (LCL or DCL) contained considerably fewer iNOS-positive cells.
