Instagram influencers attributes and parasocial relationship: A dataset from Qatar.

The dataset investigates how social media influencers' attributes affect followers' parasocial relationship. It also examines the mediating role of the parasocial relationship between the social media influencers' attributes and behavioral intentions. A snowballing sampling technique was used to target Instagram users in Qatar.

Design of potent and selective agonists for the human vasopressin V1b receptor based on modifications of [deamino-cys1]arginine vasopressin at position 4.

The glutamine(4) residue in [deamino-Cys(1)]arginine vasopressin (dAVP) was replaced by a broad series of aliphatic, aromatic, polar, and charged amino acids to give the following peptides: d[Gly(4)]AVP (1), d[Ala(4)]AVP (2), d[Abu(4)]AVP (3), d[Nva(4)]AVP (4), d[Nle(4)]AVP (5), d[Leu(4)]AVP (6), d[Ile(4)]AVP (7), d[Thi(4)]AVP (8), d[Phe(4)]AVP (9), d[Tyr(4)]AVP (10), d[Trp(4)]AVP (11), d[Asn(4)]AVP (12), d[Ser(4)]AVP (13), d[Thr(4)]AVP (14), d[Dap(4)]AVP (15), d[Dab(4)]AVP (16), d[Orn(4)]AVP (17), d[Lys(4)]AVP (18), d[Arg(4)]AVP (19), d[Har(4)]AVP (20), and d[Glu(4)]AVP (21). All peptides were synthesized by solid-phase methods using BOC chemistry for all but one peptide (8), which required the use of Fmoc chemistry. The binding and functional properties of these position 4 substituted analogues of dAVP (d[X(4)]AVP) and the previously reported d[Cha(4)]AVP (Derick et al.
