UV-irradiated methanol (CH3OH) in water ice at 3 K has been investigated with infrared spectroscopy and compared with pure methanol. The main byproducts detected are formaldehyde (H2CO), carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), and ethylene glycol (C2H4(OH)2). The production of H2CO, CO2, and CO is enhanced in water ice, resulting from cross reactions between the byproducts of methanol with those of water (OH and H2O2).

Starch has been recognized as a vital ingredient in surimi products due to its ability to absorb water, which reduces the deterioration of gels and water loss during freezing and thawing. However, it is essential to ascertain the role of starch in the formation of ice crystals and the texture of surimi gels. The impact of freeze-thaw cycles on the morphology and distribution of ice crystals, as well as the textural characteristics of gelatinized and ungelatinized starch-surimi gels was investigated.

Background: Ice hockey players have a high rate of hip pathology, which can lead to hip arthroscopy. Previous studies have not utilized team-based advanced performance statistics in the setting of hip arthroscopy in National Hockey League (NHL) players.
Purpose/hypothesis: The purpose of this study was to use team-based advanced performance statistics to evaluate postoperative performance after hip arthroscopy in NHL players in comparison with their preoperative performance and matched controls of uninjured skaters.
Metabolomics-based study on the effect of low-voltage electrostatic field treatment on the storage quality of postharvest square bamboo shoots.

Low-voltage electrostatic field (LP) enhances the freezing quality of food by increasing water supercooling and improving ice crystal morphology. This study explored the effects of LP treatment on the storage quality of square bamboo shoots using physicochemical, gas chromatography-mass spectrometry, and metabolomics methods. Results showed that with prolonged storage, the LP-treated group had lower activities of peroxidase, phenylalanine ammonia-lyase, and lower levels of malondialdehyde, cellulose, and lignin compared to the control group, while superoxide dismutase and catalase activities and shear force values were higher.

Pulmonary vein isolation (PVI) with cryoballoon (CB) ablation technology is widely used to treat drug-resistant atrial fibrillation (AF). During CB ablation, there is a possibility of forming an ice cap of contrast-color on top of the balloon. If automatic balloon deflate occurs before the ice cap dissolves, embolization to the systemic circulation is possible.
