Long-Standing oral ulcers: proposal for a new S-C-D classification system'

2009

Persistent oral ulcers and erosions can be the final common manifestation, sometimes clinically indistinguishable, of a diverse spectrum of conditions ranging from traumatic lesions, infectious diseases, systemic and local immune-mediated lesions up to neoplasms. The process of making correct diagnosis for persistent oral ulcers still represents a challenge to clinicians. Major diagnostic criteria should include the clinical appearance of both ulcer and surrounding non-ulcerated mucosa, together with the evaluation of associated signs and symptoms, such as: number (single or multiple), shape, severity of the ulcer(s), conditions of remaining mucosa (white, red or with vesiculo-bullous lesio…

Intensified job demands, stress of conscience and nurses' experiences during organizational change

2022

Background:Nurses frequently face ethically demanding situations in their work, and these may lead to stress of conscience. Working life is currently accelerating and job demands are intensifying. These intensified job demands include (1) work intensification, (2) intensified job-related planning demands, (3) intensified career-related planning demands, and (4) intensified learning demands. At the same time, many healthcare organizations are implementing major organizational changes that have an influence on personnel.Aim:The aim of the study was to investigate the association between intensified job demands and stress of conscience, and whether their association is moderated by organizatio…

Intensified job demands and job performance : does SOC strategy use make a difference?

2020

We examined intensified job demands (IJDs) and selecting-optimizing-compensating (SOC) strategies as predictors of job performance (task performance, organizational citizenship behavior). We also investigated SOC strategy use as a moderator in the linkages between IJDs and performance. We sampled three disparate occupational groups (N=4,582). We found that certain dimensions of IJDs showed significant associations with the indicators of job performance but there were also scale-based variations in these linkages, depending on the type of performance and on the sub-scale of IJDs. Specifically, some dimensions of IJDs (e.g., work intensification) related to poorer task performance whereas som…

Benson group additivity values of phosphines and phosphine oxides: Fast and accurate computational thermochemistry of organophosphorus species

2018

Composite quantum chemical methods W1X-1 and CBS-QB3 are used to calculate the gas phase standard enthalpy of formation, entropy, and heat capacity of 38 phosphines and phosphine oxides for which reliable experimental thermochemical information is limited or simply nonexistent. For alkyl phosphines and phosphine oxides, the W1X-1, and CBS-QB3 results are mutually consistent and in excellent agreement with available G3X values and empirical data. In the case of aryl-substituted species, different computational methods show more variation, with G3X enthalpies being furthest from experimental values. The calculated thermochemical data are subsequently used to determine Benson group additivity …

Latvian Translation Scene at the Beginning of the 20th Century

2021

The first decade of the 20th century was a period of huge advances and expansion in the Latvian translation scene. New, contemporary authors’ works became available to Latvian readers. The Latvian readership was consciously being integrated into general European literary trends. It was also a heyday of periodicals that published numerous translations, including numerous novels. There are countless parallel translations even reaching double digits. Translations included various genres and the traditional Latvian interest in plays was obvious. German was gradually losing its dominant positions as both a source and intermediate language, Russian was advancing. This period also saw a change of …

Isolated lip dermatitis (atopic cheilitis), successfully treated with topical tacrolimus 0.03%

2020

Background Exfoliative and erosive cheilitis, may be a source of speech and chewing discomfort, but may also be an aesthetic issue for the patients affected. Such a clinical presentation may implicate a variety of inflammatory conditions, including atopic (eczematous) cheilitis. Topical and systemic agents, e.g. corticosteroids, have been used to treat inflammatory lip conditions. Topical tacrolimus has also been used in some inflammatory lip conditions. Material and Methods We performed a retrospective clinical analysis of atopic cheilitis patients. Results Between 2015 and 2020, we addressed 7 (seven) patients with atopic dermatitis affecting only lips and were diagnosed as atopic-eczemat…

Diagnostic Challenges and Surgical Strategies in Ossification of the Posterior Longitudinal Ligament. Case Study

2021

W artykule przedstawiono przypadek pacjentki cierpiącej z powodu mielopatii szyjnej wynikającej z nierozpoznanego przez wiele lat skostnienia więzadła podłużnego tylnego (OPLL – ossification of posterior longitudinal ligament) występującego w obrębie szyjnego odcinka kręgosłupa. W pracy, poza przedstawieniem przypadku klinicznego, zaprezentowano także patofizjologię, objawy, metody diagnostyki oraz leczenia tego bardzo rzadkiego w populacji europejskiej schorzenia.

Nutritional properties and plausible benefits of Pearl millet (Pennisetum glaucum) on bone metabolism and osteoimmunology : a mini-review

2020

Bone is a hard connective tissue that undergoes a systematic renewal. This highly dynamic organ is made up of four different types of cells, however, bone formation is commonly attributed to osteoblasts and bone resorption to osteoclasts. Bone tissue formation occurs during embryonic development and in certain post-birth pathological conditions. The immune system could influence the functions of bone cells, and the crosstalk between hematopoietic, immune, and bone cells is known as osteoimmunology. Indeed, cytokines produced by immune cells, including TNF-α and IL-6, are critically implicated in bone pathogenesis. It is well established that diet plays an important role in bone health and f…

A novel intrinsically disordered outer membrane lipoprotein ofAggregatibacter actinomycetemcomitansbinds various cytokines and plays a role in biofil…

2017

Intrinsically disordered proteins (IDPs) do not have a well-defined and stable 3-dimensional fold. Some IDPs can function as either transient or permanent binders of other proteins and may interact with an array of ligands by adopting different conformations. A novel outer membrane lipoprotein, bacterial interleukin receptor I (BilRI) of the opportunistic oral pathogen Aggregatibacter actinomycetemcomitans binds a key gatekeeper proinflammatory cytokine interleukin (IL)-1b. Because the amino acid sequence of the novel lipoprotein resembles that of fibrinogen binder A of Haemophilus ducreyi, BilRI could have the potential to bind other proteins, such as host matrix proteins. However, from th…
