<i>meso</i>-Aryl Core-Modified Fused Sapphyrins: Syntheses and Structural Diversity
Two new, fused core-modified expanded
porphyrins, sapphyrins <b>3</b> and <b>4</b>, were synthesized
by a simple acid-catalyzed
condensation of electron-rich and rigid precursor, dithienothiophene
(DTT) diol, and core-modified tripyrrane. These sapphyrins exhibit
structural diversity depending upon the heteroatom present in the
macrocyclic framework, where the thiophene ring is inverted in <b>3</b>, while the selenophene ring in <b>4</b> exists in
normal and inverted form in the free base and addition of two protons
shifts the equilibrium to inverted form
Manlig impotens- Livskvalitet, stöd och information En litteraturstudie
Syftet med denna litteraturstudie var att belysa impotensens inverkan pĂ„ mĂ€ns livskvalitet samt att undersöka i vilket behov av stöd och information impotenta mĂ€n Ă€r och vilken roll sjuksköterskan kan ha för patientgruppen. Resultatet base-ras pĂ„ tio vetenskapliga artiklar, som granskats enligt Polit, et al (2001) kriterier för hur en vetenskaplig artikel. Resultatet visar att impotens har en klar pĂ„verkan pĂ„ livskvaliteten för mĂ€n. B l a kĂ€nde mĂ€nnen en förlust av sin manlighet, fick sĂ€mre sjĂ€lvkĂ€nsla och en negativ pĂ„verkan pĂ„ mannens sociala liv var tydlig. Ett behov av en mer öppen diskussion kring sexualitet efterlyses av mĂ€nnen samt bĂ€ttre information om bakomliggande orsaker och behandlingsalternativ. Sjukskö-terskan ansĂ„gs kunna ha en betydande roll för patientgruppen impotenta mĂ€n. Slutsatsen av arbetet Ă€r att man i den kliniska verksamheten mĂ„ste bli bĂ€ttre pĂ„ att integrera sexualiteten i begreppet hĂ€lsa. Viktigt Ă€r att förstĂ„ varje mans upplevelse av impotensen och pĂ„ sĂ„ sĂ€tt kunna identifiera hans behov av stöd och information.The aim of this study is to find out to what extent impotence influences a mans quality of life, further purpose is to find out what needs of support and informa-tion this group of patients have, and what role the nurse can play. The result is based on ten scientific articles, that have been scrutinized using the scientific cri-teriaâs presented by Polit et al (2001). The study shows that impotence affects a mans quality of life. Impotence often has a negative affect on menâs self-esteem and it can be an obstacle to his social life. Men expressed a need for a more open discussion on sexuality and a wider range of information. A nurse is considered to be able to contribute with knowledge and information for this group of patients. The conclusion is that people within medical services have to improve their way to integrate sexuality in the concept of health. The most important thing is to un-derstand every individualÂŽs experience of impotence, identify his needs and give him suppor
