Implantable cardioverter defibrillator deactivation and end-of-life: British Heart Rhythm Society practical consensus guideline.

Implantable cardioverter defibrillators (ICDs) are implanted in increasing numbers of patients with the aim of treating ventricular arrhythmias in high-risk patients and reducing their risk of dying. Individuals are also living longer with these devices. As a result, a greater number of patients with an ICD will deteriorate either with worsening cardiac failure, another non-cardiac condition or general frailty and will have a limited prognosis.

Hunger modulates exploration through suppression of dopamine signaling in the tail of striatum.

Caloric depletion leads to behavioral changes that help an animal find food and restore its homeostatic balance. Hunger increases exploration and risk-taking behavior, allowing an animal to forage for food despite risks; however, the neural circuitry underlying this change is unknown. Here, we characterize how hunger restructures an animal's spontaneous behavior as well as its directed exploration of a novel object.

Developing robust quantitative PCR primers for comparative biomass analysis of Tall Fescue (Festuca arundinacea) and its Epichloë endophyte.

Tall fescue ( ) is a widely adopted forage and turf grass. This is partly due to a fungal endophyte, which confers both abiotic and biotic stress tolerance. Although PCR primers exist to test for endophyte presence, these were not designed to quantitatively analyze the amount of fungus in the plant.

Sex hormone deficiency in male and female mice expressing the Alzheimer's disease-associated risk-factor TREM2 R47H variant impacts the musculoskeletal system in a sex- and genotype-dependent manner.

The R47H variant of the triggering receptor expressed on myeloid cells 2 (TREM2) is a risk factor for Alzheimer's disease in humans and leads to lower bone mass accrual in female but not male 12-mo-old mice. To determine whether, as with aging, gonadectomy results in sex-specific musculoskeletal effects, gonad removal or SHAM surgery was performed in 4-mo-old TREM2 mice and WT male and female littermates ( = 10-12/group), with sexes analyzed separately. Body weight was lower in males, but higher in females after gonadectomy, independently of their genotype.
