In Turkish we have two words, sayesinde and yüzünden that attribute causality (similar to 'due to', 'because of' but they are used in different circumstances. Sayesinde is used for giving credit to someone or something for a positive thing. Yüzünden on the other hand is mostly used for blaming, or attributing the cause of an event that turned out in a negative way. Let's see:

English	Turkish
I passed my exam thanks to you!	Senin sayende sınavımı geçtim!
I failed my exam because of you!	Senin yüzünden sınavımdan kaldım!

Beneath you can see the way in which these words change according to the person:

Saye	Singular	Plural
First person	Benim sayemde	Bizim sayemizde
Second person	Senin sayende	Sizin sayenizde
Third person	Onun/Kamil/Arkadaşım sayesinde	Onların/Onlar¹ sayesinde

Yüzünden	Singular	Plural
First person	Benim yüzümden	Bizim yüzümüzden
Second person	Senin yüzünden	Sizin yüzünüzden
Third person	Onun/Kamil/Arkadaşım yüzünden	Onların/Onlar¹ yüzünden

¹ Note how third person plural can drop its genitive suffix, just as when we conjugate hakkında.

As you can see they conjugate fairly regularly. The critical point is to decide which one to use in a given sentence, and that depends on the context; if the situation has positive connotations, then you use sayende, if the situation has bad connotations you use yüzünden.
