The association between fluoride concentrations and spontaneous humeral fracture in first-lactation dairy cows: results from two New Zealand studies.

Aim: To assess whether the fluoride concentration in the humeri of first-lactation, 2-year-old dairy cows with a spontaneous humeral fracture is significantly different from that of first-lactation, 2-year-old dairy cows without a humeral fracture.

Methods: Two studies were conducted, the first with nine bone samples from 2-year-old, first-calving dairy cows with a humeral fracture (all from the Waikato region) age-matched with seven control bone samples from the Waikato, Bay of Plenty and Manawatū-Whanganui regions. The second study used 26 bone samples from 2-year-old, first-lactation dairy cows with a humeral fracture (from the Otago, Canterbury, Southland, West Coast, Waikato and Manawatū-Whanganui regions) age-matched with 14 control bone samples (all from the Manawatū-Whanganui region or unknown).

Targeted CRISPR regulation of ZNF865 enhances stem cell cartilage deposition, tissue maturation rates, and mechanical properties in engineered intervertebral discs.

Cell and tissue engineering based approaches have garnered significant interest for treating intervertebral disc degeneration and associated low back pain due to the substantial limitations of currently available clinical treatments. Herein we present a clustered regularly interspaced short palindromic repeats (CRISPR)-guided gene modulation strategy to improve the therapeutic potential of cell and tissue engineering therapies for treating intervertebral disc disease. Recently, we discovered a zinc finger (ZNF) protein, ZNF865 (BLST), which is associated with no in-depth publications and has not been functionally characterized.

Quasi-periodic X-ray eruptions years after a nearby tidal disruption event.

Quasi-periodic eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of galaxies, repeating on timescales of hours to weeks. The mechanism behind these rare systems is uncertain, but most theories involve accretion disks around supermassive black holes (SMBHs) undergoing instabilities or interacting with a stellar object in a close orbit. It has been suggested that this disk could be created when the SMBH disrupts a passing star, implying that many QPEs should be preceded by observable tidal disruption events (TDEs).

A NOVEL FOUR-POINT SCLERAL FIXATION TECHNIQUE WITH A HYDROPHOBIC INTRAOCULAR LENS: The Loop to Optic and Trailing end to Outside Technique.

Purpose: To describe a new surgical technique that combines four-point, flanged polypropylene scleral fixation with a hydrophobic intraocular lens (IOL).

Methods: Using the Envista MX60 and 6.0 polypropylene, scleral four-point fixation was achieved using a flanged-suture technique five times in a model eye and in a case series of eight patients, retrospectively reviewed.

Therapeutic CRISPR epigenome editing of inflammatory receptors in the intervertebral disc.

Low back pain (LBP) ranks among the leading causes of disability worldwide and generates a tremendous socioeconomic cost. Disc degeneration, a leading contributor to LBP, can be characterized by the breakdown of the extracellular matrix of the intervertebral disc (IVD), disc height loss, and inflammation. The inflammatory cytokine tumor necrosis factor α (TNF-α) has multiple signaling pathways, including proinflammatory signaling through tumor necrosis factor receptor 1 superfamily, member 1a (TNFR1 or TNFRSF1A), and has been implicated as a primary mediator of disc degeneration.

A deep-sea isopod that consumes sinking from the ocean's surface.

Most deep-ocean life relies on organic carbon from the surface ocean. While settling primary production rapidly attenuates in the water column, pulses of organic material can be quickly transported to depth in the form of food falls. One example of fresh material that can reach great depths across the tropical Atlantic Ocean and Caribbean Sea is the pelagic macroalgae .

An Assessment of the Epidemiology and Herd-Level Impact of the Fractured Humerus Epidemic in New Zealand Dairy Cattle, 2007-2015: Results from Four Studies.

A multi-method approach integrating data from four independent sources was used to describe some key features of the epidemiology and estimate the herd and within-herd incidence of fractured humeri in New Zealand dairy cattle for the period 2007-2015. The first dataset was from a national case series where cases of humeral fractures in dairy cattle were identified by veterinarians across New Zealand between the 2007/2008 and 2011/2012 lactation seasons. The second dataset was from a pet food company based in the Waikato region, which collated the number of casualty first- and second-lactation cows found to have a fractured humerus post-slaughter in the 2014/2015 lactation season, and the third dataset was a case series conducted by veterinarians employed in a Waikato veterinary business, also from the 2014/2015 lactation season.

MicroRNA-409-3p/BTG2 signaling axis improves impaired angiogenesis and wound healing in obese mice.

Wound healing is facilitated by neoangiogenesis, a complex process that is essential to tissue repair in response to injury. MicroRNAs are small, noncoding RNAs that can regulate the wound healing process including stimulation of impaired angiogenesis that is associated with type-2 diabetes (T2D). Expression of miR-409-3p was significantly increased in the nonhealing skin wounds of patients with T2D compared to the non-wounded normal skin, and in the skin of a murine model with T2D.

Toward the Development of a Tissue Engineered Gradient Utilizing CRISPR-Guided Gene Modulation.

Cellular, compositional, and mechanical gradients are found throughout biological tissues, especially in transition zones between tissue types. Yet, strategies to engineer such gradients have proven difficult due to the complex nature of these tissues. Current strategies for tissue engineering complex gradients often utilize stem cells; however, these multipotent cells require direction from environmental cues, which can be difficult to control both and .

gen. nov. sp. nov., a diatom symbiont isolated from the phycosphere of .

A diatom-associated bacterium, designated as strain F10, was isolated from a pure culture of the pennate diatom A3 and has since been used to characterize molecular mechanisms of symbiosis between phytoplankton and bacteria, including interactions using diatom-derived azelaic acid. Its origin from a hypersaline environment, combined with its capacity for quorum sensing, biofilm formation, and potential for dimethylsulfoniopropionate methylation/cleavage, suggest it is within the family . Initial phylogenetic analysis of the 16S rRNA gene sequence placed this isolate within the genus, but recent genomic and phylogenomic analyses show strain F10 is a separate lineage diverging from the genus .

Low back pain (LBP) ranks among the leading causes of disability worldwide and generates a tremendous socioeconomic cost. Disc degeneration, a leading contributor to LBP, can be characterized by the breakdown of the extracellular matrix of the intervertebral disc (IVD), disc height loss, and inflammation. The inflammatory cytokine TNF-α has multiple pathways and has been implicated as a primary mediator of disc degeneration.

Deficiency of miR-409-3p improves myocardial neovascularization and function through modulation of DNAJB9/p38 MAPK signaling.

Angiogenesis is critical for tissue repair following myocardial infarction (MI), which is exacerbated under insulin resistance or diabetes. MicroRNAs are regulators of angiogenesis. We examined the metabolic regulation of miR-409-3p in post-infarct angiogenesis.

A cross-sectional evaluation of the current state of wound healing education in the United Kingdom's undergraduate medical curriculum.

Between 2013 and 2018, there has been a 71% increase in the number of patients who have required wound care in the NHS and such large numbers has placed a significant burden on healthcare systems. However, there is currently no evidence as to whether medical students are equipped with the necessary skills to deal with an increasing number of wound care related issues that patients present with. A total of 323 medical students across 18 UK medical schools completed an anonymous questionnaire evaluating the wound education received at their medical school, encompassing the volume, content, format and efficacy of teaching.

Two independent studies were conducted in northeastern Florida to determine if Biogents Gravid Trap (GAT) mosquito collections could be enhanced with a variety of substances and structural configurations. The first study baited GATs with either: 1) an infusion of mixed Southern live oak leaf () and slash pine needle () litter, 2) Biogents Lure (BG Lure), 3) yeast-derived carbon dioxide), 4) yeast-derived carbon dioxide+ BG Lure, or 5) a combination of all three. Nine mosquito species were collected from traps in the first study with >> as the top four most abundantly collected species.

Multiplex gene editing to promote cell survival using low-pH clustered regularly interspaced short palindromic repeats activation (CRISPRa) gene perturbation.

Background Aims: Lower back pain is the leading cause of disability worldwide and is often linked to degenerative disc disease (DDD), the breakdown of intervertebral discs. The majority of treatment options for DDD are palliative, with clinicians prescribing medication or physical therapy to return the patient to work. Cell therapies are promising treatment options with the potential to restore functional physiological tissue and treat the underlying causes of DDD.

Paternalism in Historical Context: Helmet and Seatbelt Legislation in the UK.

Paternalism is a frequent source of anxiety and scholarly enquiry within public health. This article examines debate in the UK from the 1950s to the early 1980s about two quintessentially paternalistic laws: those making it compulsory to use a motorcycle helmet, and a car seatbelt. This kind of historical analysis, looking at change over time and the circumstances that prevent or enable such change, draws attention to two significant features: the contingent nature of that which is perceived as paternalistic and therefore objectionable, and the wide range of arguments that can be marshalled for and against.
