Cardiac autonomic neuropathy (CAN) is a common yet frequently underdiagnosed complication of diabetes. While our previous study demonstrated the utility of multiscale cross-approximate entropy (MS-CXApEn) in detecting early CAN, the present study further investigates the use of frequency-domain coherence analysis between systolic blood pressure (SBP) and R-R intervals (RRI) and evaluates the effects of insulin treatment on autonomic function in diabetic rats. At the onset of diabetes induced by streptozotocin (STZ), rats were assessed for cardiovascular autonomic function both before and after insulin treatment.

Background: Peripheral arterial disease (PAD) is a consequence of systemic atherosclerosis, resulting in arterial narrowing and diminished blood flow, leading to complications like claudication, rest pain, ulcers, gangrene, and functional limitations. Despite its impact on cardiovascular mortality, physical function, and quality of life, PAD has received less attention than other atherosclerotic disorders. This study addresses the paucity of comprehensive clinical data on PAD in Taiwan, aiming to analyze its incidence, risk factors, pharmacological and interventional treatments, and outcomes.

For the primary prevention of atherosclerotic cardiovascular disease (ASCVD), the recommended treatment target for each modifiable risk factor is as follows: reducing body weight by 5-10%; blood pressure < 130/80 mmHg (systolic pressure < 120 mmHg in high-risk individuals); low-density lipoprotein cholesterol (LDL-C) < 100 mg/dL in high-risk individuals, LDL-C < 115 mg/dL in moderate-risk individuals, LDL-C < 130 mg/dL in low-risk individuals, and LDL-C < 160 mg/dL in those with a minimal; complete and persistent abstinence from cigarette smoking; hemoglobin A1C < 7.0%; fulfilling recommended amounts of the six food groups according to the Taiwan food guide; and moderate-intensity physical activity 150 min/wk or vigorous physical activity 75 min/wk. For the primary prevention of ASCVD by pharmacological treatment in individuals with modifiable risk factors/clinical conditions, statins are the first-line therapy for reducing LDL-C levels; some specific anti-diabetic drugs proven to be effective in randomized controlled trials for the primary prevention of ASCVD are recommended in patients with type 2 diabetes mellitus; pharmacological treatment is recommended to assist in weight management for obese patients with a body mass index ≥ 30 kg/m (or 27 kg/m who also have at least one ASCVD risk factor or obesity-related comorbidity); an angiotensin-converting enzyme inhibitor, a glucagon-like peptide-1 receptor agonist, a sodium-dependent glucose cotransporter-2 inhibitor, and finerenone can be used in diabetic patients with chronic kidney disease for the primary prevention of ASCVD.

The ability to detect single photons has led to the advancement of numerous research fields. Although various types of single-photon detector have been developed, because of two main factors-that is, (1) the need for operating at cryogenic temperature and (2) the incompatibility with complementary metal-oxide-semiconductor (CMOS) fabrication processes-so far, to our knowledge, only Si-based single-photon avalanche diode (SPAD) has gained mainstream success and has been used in consumer electronics. With the growing demand to shift the operation wavelength from near-infrared to short-wavelength infrared (SWIR) for better safety and performance, an alternative solution is required because Si has negligible optical absorption for wavelengths beyond 1 µm.

Background: Leber hereditary optic neuropathy (LHON) is mainly the degeneration of retinal ganglion cells (RGCs) associated with high apoptosis and reactive oxygen species (ROS) levels, which is accepted to be caused by the mutations in the subunits of complex I of the mitochondrial electron transport chain. The treatment is still infant while efforts of correcting genes or using antioxidants do not bring good and consistent results. Unaffected carrier carries LHON mutation but shows normal phenotype, suggesting that the disease's pathogenesis is complex, in which secondary factors exist and cooperate with the primary complex I dysfunction.
