Much effort has been devoted to the development of new donor materials for small molecule organic solar cells due to their inherent advantages of well-defined molecular weight, easy purification and good reproducibility in photovoltaic performance. Herein, we report two small molecule donors that are compatible with both fullerene and non-fullerene acceptors. Both molecules are consisted of a (E)-1,2-di(thiophen-2-yl)ethane (TVT) substituted benzo[1,2-b:4,5-b']dithiophene (BDT) as the central unit, and two rhodanine units as the terminal electron-withdrawing groups...

Stress urinary incontinence (SUI) is a condition characterized by an involuntary loss of urine occurring as result of an increase in intra-abdominal pressure due to effort or exertion or on sneezing or coughing. Estimates of its prevalence in the female population range from 10% to 40%. A literature search of the Medline, Cochrane library, EMBASE, NLH, and Google Scholar databases was done up to July 2017, restricted to English-language articles, using terms related to SUI, medical therapy, surgical therapy and treatment options...

BACKGROUND: Tension-free vaginal tape (TVT) is a popular operative treatment for stress urinary incontinence (SUI). It has a low risk of adverse events, and injuries, particularly to the bowel, are rare. Case reports that have previously discussed these injuries and subsequent removal of TVT have not provided additional insight into management of SUI after these injuries occur. CASE: A postmenopausal woman with persistent SUI presented more than 1 year after TVT placement with bowel perforation incidentally discovered on routine screening colonoscopy...

This PhD thesis is based on three original articles. The studies were performed at the Department of Obstetrics and Gynaecology, Herlev University Hospital and at the Center for Clinical Epidemiology, Odense University Hospital. 
Urinary incontinence (UI) is a frequent disorder among women, which for the individual can have physical, psychological and social consequences. The current standard of surgical treatment is the synthetic midurethral sling (MUS), which is a minimal invasive procedure.
As the synthetic MUSs (TVT,TVT-O,TOT) were introduced in the late 1990s, there are only a few studies at the long-term follow-up based on nationwide populations; only a few have reported on the risk of reoperation and there is sparse evidence on which treatment should be used subsequently to failure of synthetic MUSs...

OBJECTIVE: To establish whether the infusion method trial of void (TOV) after a mid-urethral sling procedure, in contrast to the standard auto-fill TOV, permits discharge home from recovery, as these procedures are eminently suited to same day discharge, and the delay in achieving a successful TOV often keeps the patient in hospital overnight. METHOD: A randomised controlled trial performed between December 2014 and April 2016 at the University Hospital, enrolling 40 women undergoing a mid-urethral sling procedure for stress urinary incontinence...

A series of naphthalene diimide (NDI)-based small molecules were synthesized as nonfullerene acceptors and incorporated in all-small-molecule solar cells. Three NDI-based small molecules, NDICN-T, NDICN-BT, and NDICN-TVT, were designed with different linkers between two NDI units to induce the different conjugation length and modulate the geometric structures of the NDI dimers. The small NDI-based dimer electron acceptors with slip-stacked structures that facilitate π-π stacking interactions and/or hinder excessive aggregation exhibited different morphological behaviors, such as miscibility or crystallinity in bulk heterojunction blends with 7,7'-(4,4-bis(2-ethylhexyl)-4H-silolo[3,2-b:4,5-b']dithiophene-2,6-diyl)bis(6-fluoro-4-(5'-hexyl-[2,2'-bithiophen]-5-yl)benzo[c][1,2,5]thiadiazole) (DTS-F) electron donors...
