Chemically skinned fibres allow the study of human muscle contractile function in vitro. A particularly important parameter is specific force (SF), that is, maximal isometric force divided by cross-sectional area, representing contractile quality. Although SF varies substantially between studies, the magnitude and cause of this variability remains puzzling. Here, we aimed to summarize and explore the cause of variability in SF between studies. A systematic search was conducted in Medline, Embase and Web of Science databases in June 2020, yielding 137 data sets from 61 publications which studied healthy, young adults. Five-fold differences in mean SF data were observed. Adjustments to the reported data for key methodological differences allowed between-study comparisons to be made. However, adjustment for fibre shape, swelling and sarcomere length failed to significantly reduce SF variance (I2 = 96%). Interestingly, grouping papers based on shared authorship did reveal consistency within research groups. In addition, lower SF was found to be associated with higher phosphocreatine concentrations in the fibre activating solution and with Triton X-100 being used as a skinning agent. Although the analysis showed variance across the literature, the ratio of SF in single fibres containing myosin heavy chain isoforms IIA or I was found to be consistent across research groups. In conclusion, whilst the skinned fibre technique is reliable for studying in vitro force generation of single fibres, the composition of the solution used to activate fibres, which differs between research groups, is likely to heavily influence SF values.
To examine the effectiveness of an integrated three-mode bed exit alarm system in reducing inpatient falls within an acute care hospital setting in Singapore.

A retrospective before-and-after study design was adopted.

Our results revealed that the use of bed exit alarms are associated with a reduction in falls incidence.

Bed exit alarm systems are associated with reduced fall incidence. Nonetheless, for an institution to benefit from the technology, there will be a need to take into account the effects of "alarm fatigue", ability of nurses to respond in time to alarms, and selection of right alarm mode/limits based on the patient's profile.

Dystrophic epidermolysis bullosa (DEB) is a rare inherited disorder characterized by skin fragility leading to trauma-induced subepidermal blisters and healing with scarring. DEB is caused by mutations in COL7A1, the gene encoding for type VII collagen (COLVII). Epigenetic activity The DEB inheritance trait is divided into dominant dystrophic epidermolysis bullosa (DDEB) and recessive dystrophic epidermolysis bullosa (RDEB).

Whole-exome sequencing (WES) was performed for identifying mutations in six affected individuals of five Vietnamese families.

Three novel variants in total of eight variants were found in five families. The first novel variant causing glycine substitution (c.8279G>A, p.G2760E), the remaining two novel variants resulted in splice site affecting (c.4518+2delT and c.5821-2A>G). Functional analysis indicated that the splice site at c.4518+2delT resulted in a skipping of exon 43, leading to an in-frame deletion of 12 amino acids.

Our finding expands the spectrum of COL7A1 mutations and reports altered splicing at c.4518+2delT during the processing of the pre-mRNA. This study provides an additional scientific basis for diagnosis, genetic counseling, and prognosis purposes of EB patients.

Unfortunately, mechanically testing blood clots is complicated by their softness and fragility, thus making the use of classic mounting techniques, such as clamping, challenging. This is particularly true for mechanical testing under large deformation. Here, we describe protocols for creating in vitro blood clots and securely mounting these samples on mechanical test equipment. To this end, we line 3D-printed molds with a hook-and-loop fabric that, after coagulation, provides a secure interface between the sample and device mount. In summary, our molding and mounting protocols are ideal for performing large-deformation mechanical testing, with samples that can withstand substantial deformation without delaminating from the apparatus. © 2021 Wiley Periodicals LLC.

Notably, the assembly of a central Co2 PO4 tetrahedron and four peripheral Co[P4 Mo6 ] fragments gives rise to a rare "quasi-Keggin" structure of Co4 Mo24 , in which Co linkers continue to bridge adjacent substructures, resulting in the generation of 3D framework with large cavities. Benefitting from the combination of strong reductive P4 Mo6 units and Co active centers, the photocatalytic system with Co4 Mo24 as heterogeneous catalyst exhibits excellent activity for CO2 conversion to CO, offering the CO formation rate of 1848.3 μmol g-1 h-1 with high selectivity of 97.0 %. Besides, thermogravimetric and X-ray diffraction analysis confirm that Co4 Mo24 can maintain stable during the photocatalytic reaction process.
To define the prevalence of MRI subclinical synovitis in a large cohort of JIA patients in clinical remission and to evaluate its predictive value in terms of disease flare and joint deterioration.

Ninety patients with clinically inactive JIA who underwent a contrast-enhanced (CE) MRI of a previously affected joint were retrospectively included. Each joint was evaluated for synovitis, tenosynovitis and bone marrow oedema (BMO). Baseline and follow-up radiographs were assessed to evaluate structural damage progression.

CE-MRI was acquired in 45 wrists, 30 hips, 13 ankles and 2 knees. Subclinical synovitis was detected in 59/90 (65.5%) patients and BMO in 42/90 (46.7%) patients. Fifty-seven out of 90 (63.3%) patients experienced a disease flare during follow-up. Forty-four out of 59 (74.6%) patients with subclinical synovitis experienced a disease flare versus 13/31 (41.9%) patients with no residual synovitis on MRI (p=0.002). The presence of subclinical synovitis was the best predictor of disease flare on multivariable regression analysis (HR= 2.
