Self-reported mental health status of donor sperm-conceived adults.

While donor-conceived children have similar mental health outcomes compared to spontaneously conceived children, there is an inconsistency between studies investigating mental health outcomes of donor-conceived people in adulthood. This study is an online health survey that was completed by 272 donor sperm-conceived adults and 877 spontaneously conceived adults from around the world. Donor sperm-conceived adults had increased diagnoses of attention deficit disorder (P = 0.

Systemic Delivery of Anti-Integrin αL Antibodies Reduces Early Macrophage Recruitment, Inflammation, and Scar Formation in Murine Burn Wounds.

Increased macrophage recruitment in the early stages of wound healing leads to an excessive inflammatory response associated with elevated fibrosis and scarring. This recruitment relies upon integrins on the surface of monocytes that regulate their migration and extravasation from the circulation into the wound site, where they differentiate into macrophages. The aim of this study was to determine if inhibiting monocyte extravasation from the circulation into burns would reduce macrophages numbers in burns and lead to reduced inflammation and scar formation.

Self-reported physical health status of donor sperm-conceived adults.

Donor-conceived neonates have poorer birth outcomes, including low birth weight and preterm delivery that are associated with poorer long-term health in adulthood through the developmental origins of health and disease (DOHaD) theory. The aim of this study was to conduct the first investigation of the adult health outcomes of donor-conceived people. An online health survey was completed by 272 donor sperm-conceived adults and 877 spontaneously conceived adults from around the world.

Data on keratin expression in human cells cultured with Australian native plant extracts.

Australian native plants have a long history of therapeutic use in indigenous cultures particularly for the treatment of wounds. We analysed 14 plant derived compounds from the species Pilidiostigma glabrum, Myoporum montanum, Geijera parviflora, and Rhodomyrtus psidioides for keratin 1, 5, 10 and 14 supporting the research article "Native Australian plant extracts differentially induce Collagen I and Collagen III in vitro and could be important targets for the development of new wound healing therapies" [5]. An in situ immunofluorescence assay was used in a 96 well tissue culture plate format to measure keratin expression in immortalised human keratinocytes (HaCaTs) exposed Australian native plant compounds to NMR spectra for the plant extracts are included in this article as is quantitative fluorescent intensity data of keratin 1, 5, 10 and 14 expression.

Native Australian plant extracts differentially induce Collagen I and Collagen III in vitro and could be important targets for the development of new wound healing therapies.

Australian native plants have a long history of therapeutic use in indigenous cultures, however, they have been poorly studied scientifically. We analysed the effects of 14 plant derived compounds from the species Pilidiostigma glabrum, Myoporum montanum, Geijera parviflora, and Rhodomyrtus psidioides for their potential wound healing properties by assessing their ability to induce or suppress Collagen I and Collagen III expression in human skin fibroblasts in culture. The compound 7-geranyloxycoumarin was able to significantly increase Collagen I (23.

Evaluation of a topical treatment for the relief of sensitive skin.

Background: Approximately, 50% of the population claim to have sensitive skin, which has created an important challenge for dermatologists and the cosmetic industry. This study evaluates the properties of QV Face Rescue Gel (Rescue Gel) that contains a combination of moisturizing and anti-irritant ingredients, and which is used to relieve the symptoms of sensitive facial skin.

Methods: The ability of Rescue Gel to induce collagen types I and III in cultured neonatal human foreskin fibroblasts compared to transforming growth factor beta 1, a known potent inducer of collagen types I and III, was measured using immunofluorescence staining.

In vivo delivery of functional Flightless I siRNA using layer-by-layer polymer surface modification.

Gene silencing using small interfering RNA has been proposed as a therapy for cancer, viral infections and other diseases. This study aimed to investigate whether layer-by-layer polymer surface modification could deliver small interfering RNA to decrease fibrotic processes associated with medical device implantation. Anti-green fluorescent protein labelled small interfering RNA was applied to tissue culture plates and polyurethane using a layer-by-layer technique with small interfering RNA and poly-L-lysine.

A novel murine model of hypertrophic scarring using subcutaneous infusion of bleomycin.

Background: The development of new therapies for hypertrophic scarring has been hampered by the lack of an appropriate animal model. The authors' objective was to establish a reproducible murine model of hypertrophic scarring by infusing bleomycin over a prolonged period to stimulate dermal fibroproliferation.

Methods: Osmotic pumps filled with 90 μl of 2.

Conceptualising a child-centric paradigm : do we have freedom of choice in donor conception reproduction?

Since its inception, donor conception practices have been a reproductive choice for the infertile. Past and current practices have the potential to cause significant and lifelong harm to the offspring through loss of kinship, heritage, identity, and family health history, and possibly through introducing physical problems. Legislation and regulation in Australia that specifies that the welfare of the child born as a consequence of donor conception is paramount may therefore be in conflict with the outcomes.

Tropomyosin regulates cell migration during skin wound healing.

Precise orchestration of actin polymer into filaments with distinct characteristics of stability, bundling, and branching underpins cell migration. A key regulator of actin filament specialization is the tropomyosin family of actin-associating proteins. This multi-isoform family of proteins assemble into polymers that lie in the major groove of polymerized actin filaments, which in turn determine the association of molecules that control actin filament organization.

Gamete donor medical records: whose information is it?

Is it ethical, moral and feasible to release gamete donors' medical records to conceived offspring?

Flii neutralizing antibodies improve wound healing in porcine preclinical studies.

Wound healing is an important area of widely unmet medical need, with millions of procedures carried out worldwide which could potentially benefit from a product to improve the wound repair process. Our studies investigating the actin-remodeling protein Flightless I (Flii) show it to be an important regulator of wound healing. Flii-deficient mice have enhanced wound healing in comparison to Flii overexpressing mice which have impaired wound healing.

Mouse strains for the ubiquitous or conditional overexpression of the Flii gene.

The gelsolin related actin binding protein, Flii, is able to regulate wound healing; mice with decreased Flii expression show improved wound healing whereas mice with elevated Flii expression exhibit impaired wound healing. In both mice and humans Flii expression increases with age and amelioration of FLII activity represents a possible therapeutic strategy for improved wound healing in humans. Despite analysis of Flii function in a variety of organisms we know little of the molecular mechanisms underlying Flii action.

Gender specific effects on the actin-remodelling protein Flightless I and TGF-beta1 contribute to impaired wound healing in aged skin.

Impaired wound healing in the elderly presents a major clinical challenge. Understanding the cellular mechanisms behind age-related impaired healing is vital for developing new wound therapies. Here we show that the actin-remodelling protein, Flightless I (FliI) is a contributing factor to the poor healing observed in elderly skin and that gender plays a major role in this process.

Differential effects of insulin-like growth factors on scratch wound repair in respiratory epithelial cells.

Background: Insulin-like growth factors (IGFs) I and II, being potent promoters of cellular growth and differentiation, were investigated for their effectiveness in improving the rate of scratch closure in human respiratory epithelium in vitro.

Methods: Human epithelial cell lines from the nasal, bronchial, and tracheal regions were analyzed for their response to IGF-I and IGF-II, in a confluent monolayer scratch assay. IGF-binding proteins (IGFBPs) produced by certain cells are able to reduce the effectiveness of the IGFs.
