Objective: To assess the intrarater test-retest reliability of a newly developed instrument for measuring maximum rising strength (MRS) in comparison with that of maximum knee extension strength (KES).
Design: Three replications of isometric MRS and KES were measured on three test occasions separated by 1 wk in 97 healthy men and women aged 23-90. MRS was measured in seated subjects using a dynamometer fixed on the ground and connected by an adjustable nonelastic cord to a padded belt.
Results: The intraclass coefficients (ICCs) of MRS were 0.92 and 0.93 at 60 and 70 degrees of knee flexion, respectively, and 0.98 when the mean of three highest peak values of MRS at 60 degrees and the three highest peak values at 70 degrees knee flexion on each session were considered vs. 0.95 for KES. A significant increase in MRS and KES strength was found between the first and the third sessions (+7 to 8%)(P < 0.001). No side effects of strength measurements were noticed.
Conclusion: Despite a significant learning effect, MRS measurement is reliable in men and women of a wide range of ages. Whether this instrument will be useful for targeting individuals with early sit-to-stand difficulties requires further investigation.

Objective: To investigate the color stability of a one-shade resin-based composite material (RC) and a glass-ionomer cement (GIC) after staining with plaque detectors (PDs) with different formulations and delivery forms.
Materials And Methods: Rectangular-shaped specimens (7 × 3 × 2 mm) were produced with RC (Venus Diamond One, Kulzer) and GIC (Fujy IX GP, GC) (n = 30). Further, the following PDs were used on the specimens: (1) tablets (T; Plaq-Search, TePe); (2) mouthwash (M; Plaque Agent, Miradent); and (3) light-curing liquid (L; Plaque test, Ivoclar).
Background: Intrabdominal pressure (IAP) is an important parameter. Elevated IAP can reduce visceral perfusion, lead to intraabdominal hypertension, and result in life-threatening abdominal compartment syndrome. While ingestible capsular devices have been used for various abdominal diagnoses, their application in continuous IAP monitoring remains unproven.

Background: Iliac vein compression syndrome (IVCS) impedes venous blood return from the lower extremities due to iliac vein compression, manifesting as leg swelling, varicose veins, and thrombosis. These symptoms significantly degrade quality of life. Although iliac vein stenting provides symptomatic relief, the recovery process is protracted and fraught with challenges such as in-stent restenosis and psychological distress.

One of the most problematic goals for radiation safety during spaceflight is an assessment of additional doses received by astronauts during extravehicular activity (EVA). The Pille-ISS thermoluminescent dosimeter developed by the predecessor of the Hungarian Research Network (HUN-REN) Centre for Energy Research (Budapest, Hungary) is designed for the routine dose measurements not only inside the spacecraft compartments, but also for personal dosimetric control for EVA. During almost two decades of the International Space Station (ISS) operation, the unique set of 131 EVA doses were recorded in different conditions, such as: solar activity, ISS trajectory along the South Atlantic Anomaly (SAA), and shielding conditions provided by two kinds of spacesuits: the Extravehicular Mobility Unit (EMU) and Orlan.

Aims: This study aims to translate, cross-culturally adapt, and conduct initial psychometric testing of the EBP-COQ Prof© to Bahasa Indonesia.
Background: The availability of evidence-based practice competency tools evaluating nurses' knowledge, skills attitudes and adoption in the context of Indonesian nursing practice are limited. A valid tool in EBP that measures nurses' self-perceived competency in knowledge, skills, attitudes, and utilization was used in this study for translation and psychometric validation.
