This report presents status of external and internal dose assessment of workers and introducing the structure of National Dose Registry System of Iran (NDRSI). As well as types of individual dosemeters in use, techniques for internal dose assessment are presented. Results obtained from the International Atomic Energy Agency intercomparison programme on measurement of personal dose equivalent H(p) (10) and consistency of the measured doses with the delivered doses are shown. Also, implementation of dosimetry standards, establishment of quality management system, authorisation and approval procedure of dosimetry service providers are discussed.

Thorium ore dust research applicable to mineral sands industry workers.
J Radiol Prot
January 2025
School of Medical and Health Sciences, Edith Cowan University, Joondalup, Western Australia, AUSTRALIA.
Historically, radiation exposure to mineral sands workers arose primarily from intake of thorium associated with monazite dust generated in mineral separation plants. Research investigations in the 1990s provided greater insight into the characteristics of inhaled thorium ore dust and bioassay studies inferred that some workers had accumulated significant lung burdens of thorium. Recent changes to biokinetic models have increased the radiation dose assessed to arise from thorium intake, raising questions on the appropriateness of current assumptions used in exposure assessment and feasibility of further bioassay research.

J Bone Joint Surg Am

National Cancer Institute, Cairo University, Giza, Egypt.
Background: Limb-salvage surgery for malignant bone tumors can be associated with considerable perioperative blood loss. The aim of this randomized controlled trial was to assess the safety and efficacy of the intraoperative infusion of tranexamic acid (TXA) in children and adolescents undergoing limb-salvage surgery.
Methods: All participants were <18 years of age at the time of surgery and diagnosed with a malignant bone tumor of the femur that was treated with resection and reconstruction with a megaprosthesis.
Creatine kinase and neuromuscular fatigue responses following differing spells of simulated cricket fast bowling.

Academic Partnership Unit, Leeds Trinity University, Leeds, United Kingdom.
The fast-bowling action demands repetitive high-intensity whole body movements, imposing complex physical and perceptual demands on players that vary significantly throughout the season. This study aimed to assess and establish practical methods and metrics for quantifying fatigue after four simulated fast bowling spells. Eleven senior club male fast bowlers (age 27.

A statistical procedure has been developed to derive a screening value from an observational study related to the developmental toxicity observed in loggerhead turtle (Caretta caretta) eggs exposed to long chain per- and polyfluoroalkyl substances (PFAS). A dataset of 41 nests in which the hatching rate was inversely correlated with the increase in the PFAS concentration in unhatched eggs was processed via a categorical regression approach. After outliers identification and removal, categorical regression analysis tested the relationships of the outcomes with the following parameters: perfluoro-nonanoic (PFNA), decanoic (PFDA), undecanoic (PFUdA), and dodecanoic (PFDoA) acids; perfluoroctansulfonate (PFOS); polychlorobiphenyls (PCBs) 28, 52, 101, 138, 153, 180; lead (Pb), total mercury (Hgtot), and cadmium (Cd); and other factors, such as "nest site," "clutch size," "incubation duration," and "nest minimum depth," as confounders/modifiers of the hatching rate.

January 2025
Unicycive Therapeutics, Los Altos, CA, United States.
Background: This study evaluated the combined effects of oxylanthanum carbonate (OLC), an investigational phosphate binder, and tenapanor, an approved sodium/hydrogen exchanger 3 (NHE3) inhibitor that reduces paracellular phosphate absorption, on urinary phosphate excretion in rats on a high phosphorus diet.
Methods: Sixty-four male Sprague Dawley rats were randomized into eight groups: vehicle; tenapanor (0.15 mg/kg) only; OLC (0.
