Study of plasma essential element concentrations to explore markers of acute myocardial infarction.
Biometals
February 2025
Department of Anesthesiology, Fukui Prefectural Hospital, 2-8-1 Yotsui, Fukui, 910-8526, Fukui, Japan.
Article Synopsis
- - The study investigates how different essential element concentrations (Fe, Mg, Zn, Cu, Ca, P) in plasma could serve as potential markers for acute myocardial infarction (AMI) compared to other heart diseases like angina and heart failure.
- - Findings reveal that plasma levels of cardiac troponin T (TnT) are significantly higher in AMI patients and negatively correlated with copper (Cu) and calcium (Ca) concentrations.
- - While most element levels were within normal ranges, higher magnesium (Mg) levels and lower Cu and Ca levels in AMI patients may distinguish this condition from other heart diseases.

The relatively low strength of bioabsorbable screws is a critical clinical issue. A shallower thread depth will increase a screw's strength, but the pull-out strength of the screw will decrease proportionally with the thread depth. We sought to provide further clarification of the relationships between (i) the thread depth and the pull-out strength, and (ii) the minor diameter and the shearing and bending strengths in bioabsorbable screws made of uncalcined and unsintered hydroxyapatite particles and poly-L-lactide (u-HA/PLLA).

Department of Orthopaedic Surgery, Shimane University Faculty of Medicine, Shimane, Japan.
Background: When a pilot hole is made prior to a screw's insertion into bone, the same drill bit is used irrespective of the bone quality. However, osteoporotic bone is fragile and this may affect the hole diameter, which is of particular concern in cancellous bone. In this study, the relationship between bone density and drill-hole diameter was investigated assuming a pre-drilling process in screw-only osteosynthesis in the metaphysis and epiphysis.

Shimane Institute for Industrial Technology, 1 Hokuryo, Matsue, Shimane 690-0816, Japan.
Thallium (Tl) is one of the most toxic metals and its historic use in homicides has led it to be known as "the poisoner's poison." This review summarizes the methods for identifying Tl and determining its concentrations in biological samples in recently reported poisoning cases, as well as the toxicokinetics, toxicological effects, toxicity mechanisms, and detoxication methods of Tl. Recent findings regarding Tl neurotoxicological pathways and toxicological effects of Tl during pregnancy are also presented.

Ann Clin Biochem

Department of Legal Medicine, Shimane University Faculty of Medicine, Izumo, Japan.
Article Synopsis
- Cell-free DNA (cfDNA) is DNA found in blood that increases in concentration during certain diseases, including cancers like acute promyelocytic leukaemia (APL).
- In a study, researchers observed that cfDNA levels were slightly elevated in APL patients undergoing arsenic trioxide (ATO) treatment compared to healthy controls, with changes in cfDNA corresponding to plasma arsenic levels.
- The study reported specific fragment patterns of cfDNA in APL patients, suggesting that it might be released through necrosis or neutrophil extracellular traps, but more research is needed to determine if cfDNA can serve as a reliable biomarker for APL treatment effectiveness.

Methods: Nine types of custom-made screws with the only changed variable being the thread depth were manufactured.
Silicon nanorod formation from powder feedstock through co-condensation in plasma flash evaporation and its feasibility for lithium-ion batteries.
Sci Rep

Department of Materials Engineering, The University of Tokyo, Tokyo, 113-8656, Japan.
Si nanowires/nanorods are known to enhance the cycle performance of the lithium-ion batteries. However, viable high throughput production of Si nanomaterials has not yet attained as it requires in general expensive gas source and low-rate and multiple-step approach. As one of the potential approaches, in this work, we report the fast-rate Si nanorod synthesis from low-cost powder source by the modified plasma flash evaporation and the fundamental principle of structural formation during gas co-condensation.

Gallium antimonide (GaSb) is a group III-V compound semiconductor with a comparatively narrow band gap energy (0.73 eV at 300 K) that allows efficient operation in the near-infrared region. This property may be useful in developing new biomedical instruments such as epidermal optoelectronic devices.

Although brown rice (BR) contains significantly higher levels of nutrients than the traditionally used polished white rice (WR), its consumption among the population is still not noteworthy. WR and BR are essentially same grain. The only difference between the two is the application of an exhaustive milling procedure during the processing of WR that removes all other layers of the grain except the portion of its white endosperm.

Brown rice contains many ingredients that might protect against cognitive decline and Alzheimer's disease. However, brown rice is very hard, difficult to cook, and is poorly digested; thus, it is difficult to eat long-term. To solve these problems, ultra-high hydrostatic pressurizing brown rice (UHHPBR) was prepared.

Department of Legal Medicine, Shimane University School of Medicine, 89-1 Enya, Izumo, Shimane 693-8501, Japan.
In the present study, we used micro-Raman spectroscopy with high-resolution analysis to discriminate between bloodstains from infants and bloodstains from adults. Raman peaks were detected at 674, 754, 976, 1002, 1105, 1127, 1176, 1248, 1340, 1368, 1390, 1560, and 1611 cm ; these peaks were derived from hemoglobin, albumin, and glucose. However, a peak was obtained at 1105 cm , which was assigned to histidine; this peak was observed only for bloodstains from adults.

Background: Alzheimer's disease (AD) is the most common form of dementia and the number of AD patients continues to increase worldwide. Components of the germ layer and bran of Brown rice (BR) help maintain good health and prevent AD. Because the germ layer and bran absorb little water and are very hard and difficult to cook, they are often removed during processing.

Article Synopsis
- Pyrrocorphin is a unique compound with an air-sensitive structure that has a reduced hexahydroporphyrin core, and pyrrolidine-fused variants are less sensitive to air.
- The study involved creating a Ni(II) complex from pyrrocorphin, which displayed interesting bond characteristics and was fully characterized using various advanced techniques.
- Results indicated that as the porphyrin ring structure is reduced, the binding affinity of pyridine to the Ni(II) complex increases significantly, establishing a new order of binding strength compared to other known porphyrinoids.
Instantaneous formation of SiO nanocomposite for high capacity lithium ion batteries by enhanced disproportionation reaction during plasma spray physical vapor deposition.
Sci Technol Adv Mater
November 2016
Department of Materials Engineering, The University of Tokyo, Hongo , Japan.
Nanocomposite SiO particles have been produced by a single step plasma spray physical vapor deposition (PS-PVD) through rapid condensation of SiO vapors and the subsequent disproportionation reaction. Core-shell nanoparticles, in which 15 nm crystalline Si is embedded within the amorphous SiO matrix, form under typical PS-PVD conditions, while 10 nm amorphous particles are formed when processed with an increased degree of non-equilibrium effect. Addition of CH promotes reduction in the oxygen content of SiO , and thereby increases the Si volume in a nanocomposite particle.

We describe a flexible capacitance-type sensor that can detect an approaching human without contact, fabricated by developing and applying duplex conductive-ink printing to a film substrate. The results of our calculations show that the difference in size between the top and bottom electrodes of the sensor allows for the spatial extension of the electric field distribution over the electrodes. Hence, such a component functions as a proximity sensor.

Background: The functional components of mulberry leaves have attracted the attention of the health food industry, and increasing their concentrations is an industry goal. This study investigated the effects of solar radiation, which may influence the production of flavonol and 1-deoxynojirimycin (DNJ) functional components in mulberry leaves, by comparing a greenhouse (poor solar radiation) and outdoor (rich solar radiation) setting.
Results: The level of flavonol in leaves cultivated in the greenhouse was markedly decreased when compared with those cultivated outdoors.
