Chambered warm moist air eyelid warming devices – a review

2021

Background Eyelid warming is an important treatment for meibomian gland dysfunction (MGD). Specialized chambered devices, using warm moist air have been developed. Purpose To critically evaluate the literature on the safety and efficacy of chambered warm moist air devices in MGD treatment and pinpoint areas of future research. Methods PubMed and Embase were searched on 06 June 2021. The search term was ‘(warm OR heat OR steam OR goggle OR spectacle OR moist air) AND (meibomian OR MGD OR blepharitis OR eyelid OR dry eye OR DED)’. All relevant articles with available English full text were included. Results Eighteen articles assessing the application of chambered warm moist air eyelid warming…

Serum Heat Shock Protein 60 in Acute Heart Failure: A New Biomarker?

2012

Heat shock protein 60 (HSP60) is a mitochondrial protein constitutively expressed in the majority of cells, and its expression is up-regulated by a variety of stressors. In heart failure, HSP60 is released from cardiomyocytes. The authors speculate that increased serum HSP60 (sHSP60) may be related to the severity of heart failure. This investigation sought to assess the association between sHSP60 and the composite end point of death ⁄ readmission in patients with acute heart failure (AHF). A total of 132 consecutive patients were admitted for AHF. The independent association between sHSP60 and the end point was assessed with Cox regression. During a median follow-up of 7 months (interquart…

Individualized analysis of skin thermosensory thresholds and sensitivity in heat-sensitive people with multiple sclerosis

2020

We investigated whether and how multiple sclerosis (MS) alters thresholds for perceiving increases and decreases in local skin temperature, as well as the sensitivity to progressively greater temperature stimuli, amongst heat-sensitive people with MS. Eleven MS patients (5 M/6 F; 51.1 ± 8.6 y, EDSS 5.7 ± 1.9) and 11 healthy controls (CTR; 7 M/4 F; 50.3 ± 9.0 y) performed warm and cold threshold tests on a hairy skin site, on both sides of the body. They also underwent a thermosensitivity test where they rated (visual analogue scale) perceived magnitude of 4 local skin stimuli (i.e. 22, 26, 34, 38°C). Individual thresholds and slopes of linear regression for thermosensitivity were z-transfor…

Heat shock protein expression and anti-heat shock protein reactivity in renal cell carcinoma.

2002

Heat shock proteins (HSP) are families of highly conserved proteins which are induced in cells and tissues upon exposure to extreme conditions causing acute or chronic stress. They exhibit distinct functions and have been implicated in the pathogenesis of a number of diseases, including cancer. A causal relationship between HSP expression and immunogenicity has been demonstrated in murine and human tumors and is also associated with the immune response. In order to investigate the correlation of HSP expression and their immunogenic potential in renal cell carcinoma (RCC), we here analyzed (i) the protein expression profile of various members of the HSP family in untreated and interferon (IF…

Metodi Chemiometrici per la sintesi razionale di Nanowires di ZnO per l'elettronica su Circuiti

2019

I nanowires di ZnO (ZnO NWs) rappresentano uno dei materiali 1D di maggiore interesse per lo sviluppo di sensori e/o trasduttori, date le loro ot time proprietà piezoelettriche e semiconduttive1 . Tuttavia, la sintesi chimica di ZnO NWs ad alto “aspect ratio” da soluzione acquosa a basse temperature stemi elettronici completi. Recentemente abbiamo sviluppato2 un metodo per il controllo razionale della sintesi di nanowires di ZnO (Figura 1) su supporti conduttivi in rame per la realizzazione di nanotrasduttori...

Home and mental ill-health: twenty dimensions

2017

In the context of psychiatric rehabilitation and care, home is often associated with health. In the context of deinstitutionalization, however, home has increasingly become the primary site of psychiatric suffering. Drawing on a two-year ethnographic research project with a drama group for young adult mental healthcare service users living in supported housing facilities, this paper presents twenty dimensions of home through which mental ill-health can be approached as a bodily experienced, and discursively and medically structured form of being in the world. These dimensions are here offered as a framework for further exploration of the social, spatial, temporal, structural and embodied as…

"Jak gdyby to była prawda..." : podejrzany realizm i podejrzany modernizm Tadeusza Rittnera

2020

This paper is an attempt at redefining selected plays written by Tadeusz Rittner in the modernist and symbolist convention. In the 1950s, they were evaluated by Zbigniew Raszewski as among the playwright’s lesser achievements. I have analysed three texts: the one-act plays Sąsiadka (“The Neighbour”) and Odwiedziny o zmroku (“A Visit at Dusk”) as well as the play Don Juan. There is no doubt that the author did not avoid stylistic exaggeration in his modernist works, but one can also find some distance from the conventions of the Young Poland period as well as the use of the grotesque, theatrical sham, and the poetics of intimate drama in these plays. Rittner’s Viennese character is an alibi …

The molecular anatomy of human Hsp60 and its effects on Amyloid-β peptide

Heat Shock Protein 60 (HSP60) is ubiquitous and highly conserved, being present in eukaryotes and prokaryotes, including pathogens. This chaperonin is typically considered a mitochondrial protein but it is also found in other intracellular sites, extracellularly and in circulation. HSP60 is an indispensable component of the Chaperoning System and plays a key role in protein quality control, preventing off-pathway folding events and refolding misfolded proteins. This makes HSP60 a putative therapeutic agent for neurodegenerative diseases associated with aggregation of misfolded proteins, for example, Alzheimer’s Disease. We produced and purified recombinant human HSP60 and investigated the e…

Case-specific performance of MM-PBSA, MM-GBSA, and SIE in virtual screening.

2015

In drug discovery the reliable prediction of binding free energies is of crucial importance. Methods that combine molecular mechanics force fields with continuum solvent models have become popular because of their high accuracy and relatively good computational efficiency. In this research we studied the performance of molecular mechanics generalized Born surface area (MM-GBSA), molecular mechanics Poisson-Boltzmann surface area (MM-PBSA), and solvated interaction energy (SIE) both in their virtual screening efficiency and their ability to predict experimentally determined binding affinities for five different protein targets. The protein-ligand complexes were derived with two different app…
