Investigation of the Ocular Response and Corneal Damage Threshold of Exposure to 28 GHz Quasi-millimeter Wave Exposure.

Electromagnetic radiation energy at millimeter wave frequencies, typically 30 GHz to 300 GHz, is ubiquitously used in society in devices for telecommunications; radar and imaging systems for vehicle collision avoidance, security screening, and medical equipment; scientific research tools for spectroscopy; industrial applications for non-destructive testing and precise measurement; and military and defense applications. Understanding the biological effects of this technology is essential. We have been investigating ocular responses and damage thresholds comparing various frequencies using rabbit eyes and dedicated experimental apparatus.

Two Cases of Menkes Disease With Similar Intracranial Arterial Tortuosity on Brain Magnetic Resonance Imaging.

Menkes disease is an X-linked recessive genetically inherited metabolic disease caused by an ATP7A gene abnormality that gives rise to impaired copper absorption. Copper deficiency causes symptoms such as characteristic abnormalities in the hair and vascular disorders. Brain MRI findings include a high-signal intensity in the temporal lobe white matter on T2-weighted images and delayed myelination.

Primary Cardiac Lymphoma With Dramatic Response to Chemotherapy Diagnosed by Transvenous Biopsy.

Primary cardiac lymphoma is a rare disease with the potential to be fatal. This case reports a patient who developed primary cardiac lymphoma resulting in cardiac tamponade. Despite a compromised general condition, the lymphoma was diagnosed through a transvenous tumor biopsy.

Association Between Sarcopenic Obesity and Activities of Daily Living in Individuals with Spinal Cord Injury.

: Sarcopenic obesity adversely affects physical function and activities of daily living (ADL) in older individuals and patients undergoing rehabilitation. This condition is also common in individuals with spinal cord injury (SCI); however, its relationship with ADL in this group remains unclear. Hence, this study examined the association between sarcopenic obesity and ADL in individuals with SCI.

Discordant Diagnosis of Coronary Microvascular Dysfunction by Microvascular Resistance Reserve: Transthoracic Doppler Echocardiography vs Bolus Thermodilution Method.

Background: Epicardial stenosis and coronary microvascular dysfunction (CMD) may coexist in patients with chronic coronary syndrome (CCS). Microvascular resistance reserve (MRR) has been demonstrated to be a valid cross-modality metric using continuous saline infusion thermodilution and intracoronary Doppler flow velocity methods. This study aimed to investigate the prevalence and diagnostic concordance of CMD defined by MRR using two methods-stress transthoracic Doppler echocardiography (S-TDE) and the invasive bolus thermodilution method (B-Thermo)-in patients with functionally significant epicardial stenosis.

Prognostic Value of Endogenous-Type Coronary Microvascular Dysfunction After Elective Percutaneous Coronary Intervention.

Background: Global coronary flow reserve (G-CFR) impairment represents coronary microvascular dysfunction (CMD) and correlates with poor prognosis. Hyperemic coronary flow is reduced in conventional CMD, but normal or mildly reduced with elevated resting flow in endogenous-type CMD (E-CMD). This retrospective study assessed the prognostic value of post-percutaneous coronary intervention (PCI) CMD, focusing on E-CMD.

Balance Ability Characteristics and Related Factors in Athletes Across Different Sports: A Preliminary Study.

Background: We conducted a cross-sectional study to examine two-leg- and one-leg-type balance characteristics in athletes and explore factors related to their balance ability.

Methods: A total of 213 participants, including athletes from various sports (gymnastics, boat racing, swimming, soccer, judo, and baseball) and non-athletes, were included (142 men, 71 women, average age 21.5 ± 2.

Inversion of circularly polarized luminescence by electric current flow during transition.

The development of chiral compounds exhibiting circularly polarized luminescence (CPL) has advanced remarkably in recent years. Designing CPL-active compounds requires an understanding of the electric transition dipole moment () and the magnetic transition dipole moment () in the excited state. However, while the direction and magnitude of can, to some extent, be visually inferred from chemical structures, remains elusive, posing challenges for direct predictions based on structural information.

Dithienonaphthobisthiadiazole synthesized by thienannulation of electron-deficient rings: an acceptor building unit for high-performance π-conjugated polymers.

The development of building units for π-conjugated polymers is a driving force in advancing the field of organic electronics. In this study, we designed and synthesized dithienonaphthobisthiadiazole (TNT) as a thiophene-fused acceptor (A) building unit and two TNT-based π-conjugated polymers named PTNT2T and PTNT1-F. We found that the microwave-assisted thiophene annulation reaction (thienannulation) of arylethynylated naphthobisthiadiazole (NTz) C-H functionalization effectively produced TNT moieties.

Impact of coronary revascularization on coronary flow capacity measured by transthoracic Doppler echocardiography in patients with chronic coronary syndrome.

Coronary flow capacity (CFC) integrates quantitative assessment of hyperemic myocardial blood flow and coronary flow reserve. We aimed to evaluate the effect of elective percutaneous coronary revascularization (PCI) on CFC using serial stress transthoracic Doppler echocardiography (STDE). Overall, 148 stable patients underwent STDE of the left anterior descending arteries (LAD), before and after elective PCI.

Unlabelled: We present a case of BK polyomavirus (BKV) nephropathy (BKVN) after heart transplantation (HTx). The patient was a male with non-ischemic cardiomyopathy who received HTx at the age of 56 years [serum creatinine (sCre) at the time of HTx: 0.89 mg/dl].

Secretoglobin 3A2 peptides have therapeutic potential for allergic airway inflammation.

Three isoforms of secretoglobin (SCGB) 3A2, namely type A, B, and C, are endogenously produced through alternative splicing. SCGB3A2 type A, the correctly spliced major type, begins to be expressed from embryonic day 11.5 in mice and shows various physiological activities such as promoting lung maturation and bronchial branching, anti-inflammatory effects, and ameliorating induced pulmonary fibrosis.
