Women's experiences and perception of symptomatic pelvis organ prolapse: A Cross sectional study from Uttarakhand, India.

Background: Pelvic Organ Prolapse (POP) negatively affects the health of a woman in terms of physical, social and emotional wellbeing.

Objective: The aim of this study was to elucidate the experience of living with prolapse and its impact on daily life.

Methods: Women undergoing surgery for pelvic organ prolapse were interviewed to evaluate their sociodemographic profile with subsequent impact on their daily life.

Structure-Function of the High Affinity Substrate Binding Site (S1) of Human Norepinephrine Transporter.

The human norepinephrine transporter (hNET) is a member of the neurotransmitter/sodium symporter family, which also includes the neuronal monoamine transporters for serotonin (SERT) and dopamine (DAT). Its involvement in chronic pain and many neurological disorders underlies its pharmaceutical importance. Using the X-ray crystal structures of the human serotonin transporter (hSERT) (PDB 5I6X) and dopamine transporter (dDAT) (PDB 4M48 and PDB 4XPA) as templates, we developed molecular models for norepinephrine (NE) bound to its high affinity binding site (S1) in the hNET.

'Messy' Processing of χ-conotoxin MrIA Generates Homologues with Reduced hNET Potency.

Integrated venomics techniques have shown that variable processing of conotoxins from resulted in a dramatic expansion in the number of expressed conotoxins. One conotoxin from , the χ-conotoxin MrIA, is a selective inhibitor of human norepinephrine transporters (hNET) and therefore a drug candidate for attenuating chronic neuropathic pain. It has been found that "messy" processing of the MrIA transcripts results in the expression of MrIA analogs with different truncations of the pro-peptide that contains portions of the MrIA molecule.

Inhibition of the norepinephrine transporter by χ-conotoxin dendrimers.

Peptide dendrimers are a novel class of macromolecules of emerging interest with the potential of delayed renal clearance due to their molecular size and enhanced activity due to the multivalency effect. In this work, an active analogue of the disulfide-rich χ-conotoxin χ-MrIA (χ-MrIA), a norepinephrine reuptake (norepinephrine transporter) inhibitor, was grafted onto a polylysine dendron. Dendron decoration was achieved by employing copper-catalyzed alkyne-azide cycloaddition with azido-PEG chain-modified χ-MrIA analogues, leading to homogenous 4-mer and 8-mer χ-MrIA dendrimers with molecular weights ranging from 8 to 22 kDa.
