The health burden of myocardial infarction is rising for middle-aged women and they are underrepresented in research of cardiovascular diseases. The aim of this qualitative study was to explore how life had been for middle-aged women before they suffered a myocardial infarction (MI). Through a health care register, we identified all women (n = 46) under 65 years of age in a defined region in southeast Sweden who had suffered an MI the past 2 years and a strategic selection of n = 16 women from these was made. These selected women were interviewed and their narratives were interpreted by qualitative content analysis. The qualitative interviews generated five general themes: “Serious life events”, “Negative affectivity”, “Loneliness”, “Being a good girl” and “Lack of control”. The interviews revealed that many of these women had been exposed to extreme and repeated traumatic life events in their lives. Many had a cynical attitude towards others, felt lonely and experienced a lack of social support. Many of these women endeavored to “be a good girl”, which was a special psychosocial phenomenon found. This study uncovered that these women before they suffered an MI were affected by a variety of psychosocial factors. The study stresses the importance of psychosocial risk factors in the assessment of middle-aged women’s risk profile for MI. A general conclusion for clinical practice is that in the assessment of the individual risk for myocardial infarction for middle-aged women, potential psychosocial factors might also be considered.

Primary Sjogren's syndrome(psS)is one of the most widespread autoimmune diseases with unknown origin,characterized by a lymphocytic infiltrate of the exocrine glands and the production of anti-SSA/Ro and anti-SSB/La antibodies that cause dysfunction and destruction mainly of salivary and lachrymal glands,leading to dry eyes and dry *** the absence of a standardized evidence-based screening tool to decide which patients with dry eye must be referred for study of this pathology.

There is an urgent need to identify new drug targets for Alzheimer's disease(AD). While new immunotherapies show promise, clinical benefit appears low, and side effects are high. A greater understanding of the disease mechanisms driving AD is an essential factor that will facilitate the identification of new, effective drug targets.

Rational molecular design of efficient yellow-red dendrimer TADF for solution-processed OLEDs: a combined effect of substitution position and strength of the donors

引用

Science China Chemistry 2024年第5期67卷 1613-1623页

作者： Changfeng Si Dianming Sun tomas Matulaitis David B.Cordes Alexandra M.Z.Slawin Eli Zysman-Colman Organic Semiconductor Centre EaStCHEM School of ChemistryUniversity of St AndrewsSt AndrewsKY169STUK

The development of high-performance solution-processed red organic light-emitting diodes(OLEDs) remains a challenge,particularly in terms of maintaining efficiency at high luminance. Here, we designed and synthesized four novel orange-red thermally activated delayed fluorescence(TADF) dendrimers that are solution-processable: 2GCz BP, 2DPACz BP, 2FBP2GCz and 2FBP2DPACz. We systematically investigated the effect of substitution position and strength of donors on the optoelectronic properties. The reverse intersystem crossing rate constant(kRISC) of the emitters having donors substituted at positions 11and 12 of the dibenzo[a,c]phenazine(BP) is more than 10-times faster than that of compounds substituted having donors substituted at positions 3 and 6. Compound 2DPACz BP, containing stronger donors than 2GCz BP, exhibits a red-shifted emission and smaller singlet-triplet energy splitting, ΔE_(ST), of 0.01 e V. The solution-processed OLED with 10 wt% 2DPACz BP doped in m CP emitted at 640 nm and showed a maximum external quantum efficiency(EQE_(max)) of 7.8%, which was effectively maintained out to a luminance of 1,000 cd m-2. Such a device's performance at relevant display luminance is among the highest for solution-processed red TADF OLEDs. The efficiency of the devices was improved significantly by using 4Cz IPN as an assistant dopant in a hyperfluorescence(HF) configuration, where the 2DPACz BP HF device shows an EQEmaxof 20.0% at λEL of 605 nm and remains high at 11.8% at a luminance of 1,000 cd m-2, which makes this device one of the highest efficiency orange-to-red HF SP-OLEDs to date.
