Participants assigned to RET completed 87% of training sessions and exhibited strength increases between 16 and 34% for eight lifts tested (Hedges' g range 0.47-0.78). The treatment by time interaction for perceived improvement (F
=16.94, p<0.001) was characterized by greater perceived improvement since baseline for RET at each time point, until the 12-month follow-up. ABT199 Effects were not significant for other outcomes (p>0.05). RET caused no adverse events.
After 16weeks of RET, GWV with CMP reported improvements in their condition and exhibited increases in muscular strength, without symptom exacerbation or reductions in total physical activity.

An adverse side-effect of Liraglutide (LG), a Glucagon-Like Peptide 1 (GLP1)-analog commonly used in treatments for diabetes, is positive chronotropy. The goal of this study is to investigate on the mechanism of this drug-induced chronotropy and explore potential means to mitigate this side-effect so as to maximize the therapeutic benefits from LG.
Experiments were conducted with 1) Isolated rabbit hearts in a Langendorff set-up to assess for direct effects of drug actions and 2) Murine cardiomyocytes isolated from the sino-atrial node (SAN) to assess the effects of LG on spontaneous action potential (AP) firing and the hyperpolarization-activated current I
.
LG induced a dose-dependent increase in heart rate. Its effects on sinus node automaticity, which were not suppressed during β-blockade with Propranolol, were abolished by I
blockade with Ivabradine. In isolated murine SAN myocytes, LG increased spontaneous AP firing frequency by an increase in diastolic depolarization slope without changing other electrophysiological parameters.
LG-induced positive chronotropy is partly due to a direct effect on the SAN and is independent of the adrenergic cascade and extrinsic autonomic reflex mechanisms. The direct LG-associated increase in heart rate should be mitigated with I
blockers rather than β-blockade.

Age-related macular degeneration (AMD) and high myopia are frequent causes of progressive visual impairment, so it is critical to identify animal models with resembling human retinal physiology, AMD and high myopia pathological features for therapeutic studies.
We screened elderly cynomolgus monkeys for fundus lesions by slit-lamp biomicroscope combined with fundus pre-set lens and further examined positive cases by color fundus photography (CFP), optical coherence tomography (OCT), fundus fluorescein angiography (FFA), streak retinoscopy, and A-scan ultrasonography.
Among the 156 animals examined, 10 males and 5 females (30 eyes) exhibited fundus abnormalities (9.6% prevalence). Multi-modal imaging revealed drusen in 20 eyes of 11 animals (prevalence rate of 7.1%), tessellated fundus in 22 eyes of 11 animals, and myopia choroidal neovascularization (CNV) in 4 eyes of 3 animals.
Aged cynomolgus monkeys exhibit spontaneous fundus lesions resembling human AMD and high myopia, which could be an ideal model for clinical research.

Gulf War Illness (GWI) is a chronic, debilitating, multi-symptom condition affecting as many as one-third of the nearly 700,000U.S. troops deployed to the Middle East during the 1990-1991 Gulf War (GW). The treatment of GWI relies on symptom management. A common challenge in studying the efficacy of interventions for symptom management is participant recruitment related to factors such as the burden of travelling to study sites and the widespread dispersion of Veterans with GWI. The goal of this study is to assess the efficacy of a novel low-risk therapeutic agent, Bacopa monnieri, for cognitive function in Veterans with GWI and to evaluate the utility of a remote patient-centric study design developed to promote recruitment and minimize participant burden.
To promote effective participant recruitment, we developed a remote patient-centric study design. Participants will be recruited online through social media and through a web-based research volunteer list of GW Veterans. An online assessment platform will be used, and laboratory blood draws will be performed at clinical laboratory sites that are local to participants. Furthermore, the assigned intervention will be mailed to each participant.
These study design adaptations will open participation to Veterans nearly nationwide and reduce administrative costs while maintaining methodologic rigor and participant safety in a randomized, placebo-controlled phase II clinical trial.

Whereas the reciprocal interactions between these two cell populations in kidney development have been studied extensively, the mechanisms generating them remain elusive. Here, we show that the mouse cell lineage that forms nephric mesenchyme develops as a subpopulation of Tbx6-expressing mesodermal precursor derivatives of neuro-mesodermal progenitors (NMPs) under the condition of bone morphogenetic protein (BMP)-signal-dependent Osr1 expression. The Osr1-expressing nephric mesenchyme precursors were confirmed as descendants of NMPs because they were labeled by Sox2 N1 enhancer-EGFP. In Tbx6 mutant embryos, nephric mesenchyme changed its fate into neural tissues, which reflected its NMP origin. In Osr1 mutant embryos, the specific region of the Tbx6-expressing mesoderm precursor, which normally expresses Osr1 and develops into the nephric mesenchyme, instead expressed the somite marker FoxC2.
