Objective: To investigate the relationship between postprandial blood glucose (PBG), fasting insulin (FINS), and glycated hemoglobin (HbA1c) levels early diabetic nephropathy in patients with type 2 diabetes. Methods: 96 cases of diabetes mellitus treated our hospital from May 2021 to 2022 were selected as research subjects. The divided into two groups according urinary albumin excretion rate (...

In this paper a new optical channel drop filter (CDF) based on two dimensional (2-D) photonic crystals (PhC) with hexagonal shaped structure is proposed and numerically demonstrated by using the finite-difference-time-domain (FDTD) and plane-wave-expansion (PWE) techniques. Photonic crystals (PhCs) are artificial dielectric nanostructure materials in which a periodic modulation of the material ...

Diamond-structured colloidal photonic crystals are much sought-after for their applications in visible light management because of ability to support a complete band gap (PBG). Howev...

We describe the engineering of the electromagnetic vacuum in a 2D–3D photonic bandgap (PBG) hetero-structure. This facilitates the development of novel active devices and the observation of novel quantum electrodynamic phenomena. We consider a specific architecture suitable as an all-optical micro-transistor capable of novel ultra-fast response with low switching power requirements. This relies...

Systemic administration of cholecystokinin (CCK) inhibits a subpopulation of rostral ventrolateral medulla (RVLM) presympathetic vasomotor neurons. This study was designed to determine whether this effect involved subdiaphragmatic vagal afferents and/or central N-methyl-d-aspartic acid (NMDA) receptors. Recordings were made from CCK-sensitive RVLM presympathetic vasomotor neurons in halothane-a...

The effects of dietary manipulations on excretion of the porphyrin precursors, delta-aminolevulinic acid (ALA), and porphobilinogen (PBG) were studied in eight patients with acute intermittent porphyria. Three diet periods of 9-17 days comprised each study. In each patient, a "baseline" protein, fat, and carbohydrate intake was kept constant throughout. In addition, during the first diet period...

Objective: This study aims to explore the correlation between free-triiodothyronine (FT3)-to-free-thyroxine (FT4) ratio (FT3/FT4) and diabetic kidney disease (DKD) in patients with type 2 diabetes mellitus (T2DM). Methods: retrospectively analyzed 1729 T2DM hospitalized Department of Endocrinology, Peking University International Hospital, from January 2017 August 2021, including 1075 males 654...

In this work, the transfer matrix method (TMM) is employed to investigate optical properties of one-dimensional periodic and quasiperiodic photonic crystals containing nematic liquid crystal (NLC) layers. This structure expressed as (ABC)J(CBA)J made alternated layers isotropic dielectrics SiO2 (A), BGO (B) (C). The simulation study shows that proposed ternary configuration exhibits tunable def...

Photonic Crystals (PhC) are periodically structured dielectric materials that have been subject to extensive research efforts over the last two decades. PhC known for slow-light phenomenon, which increases interaction time between light and target gas, thereby enhancing sensitivity when applied sensors. Slow is best realized using three-dimensional (3D) with a complete photonic band-gap (PBG). ...

Phenylbiguanide (PBG) stimulates cardiopulmonary receptors and cardiovascular reflex responses, including decreases in blood pressure and heart rate mediated by the brain stem parasympathetic cardiac neurons in the nucleus ambiguus and nucleus tractus solitarius (NTS). Electroacupuncture (EA) at P5-6 stimulates sensory fibers in the median nerve and modulates these reflex responses. Stimulation...
