To nap or not? Evidence from a meta-analysis of cohort studies of habitual daytime napping and health outcomes.

Habitual daytime napping is a common behavioral and lifestyle practice in particular countries and is often considered part of a normal daily routine. However, recent evidence suggests that the health effects of habitual daytime napping are controversial. We systematically searched PubMed, Web of Science, Embase, and Cochrane Library databases from inception to March 9, 2024, to synthesize cohort studies of napping and health outcome risk.

Impact of body mass index on primary immunoglobulin A nephropathy prognosis: a systematic review and meta-analysis.

Purpose: The impacts of body mass index (BMI) on the prognosis of primary IgA nephropathy (IgAN) remain controversial. This systematic review and meta-analysis aimed to solve these issues.

Methods: We searched the PubMed, EMBASE, and Cochrane Library to screen articles investigating the BMI and primary IgAN.

Carbon nanotube-based flexible electrothermal film heaters with a high heating rate.

High-performance, flexible film heaters with carbon nanotube transparent conducting films are easily fabricated by both a rod-coating method and a spraying method. The main conclusion we have reached is that the film demonstrates a heating rate of 6.1°C s at 35 V and sheet resistance as low as 94.

[Significance of serum cholesterol and fibrinogen in evaluating the risk of glomerulosclerosis in children with nephrotic syndrome].

Objective: To investigate the significance of serum cholesterol and fibrinogen (Fib) in evaluating the risk of glomerulosclerosis in children with nephrotic syndrome.

Methods: Sixty-three children with primary nephrotic syndrome were divided into two groups according to their pathological types: minimal change glomerulopathy (MCG) (n=39) and focal segmental glomerulosclerosis (FSGS) groups (n=24). Serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-HDL-C and Fib and 24-hour urinary protein excretion were retrospectively analyzed.

[A clinico-pathological comparison between Henoch-Schonlein purpura nephritis and IgA nephropathy in children].

Objective: To study the difference in clinico-pathological features between IgA nephropathy (IgAN) and Henoch-Schonlein purpura nephritis (HSPN) in children.

Methods: The medical data of 103 children with HSPN and 61 children with IgAN were retrospectively studied.

Results: There were no significant differences in age, sex and disease course between the HSPN and IgAN groups (P>0.

Improved color rendering of phosphor-converted white light-emitting diodes with dual-blue active layers and n-type AlGaN layer.

An InGaN/GaN blue light-emitting diode (LED) structure and an InGaN/GaN blue-violet LED structure were grown sequentially on the same sapphire substrate by metal-organic chemical vapor deposition. It was found that the insertion of an n-type AlGaN layer below the dual blue-emitting active layers showed better spectral stability at the different driving current relative to the traditional p-type AlGaN electron-blocking layer. In addition, color rendering index of a Y3Al5O12:Ce3+ phosphor-converted white LED based on a dual blue-emitting chip with n-type AlGaN reached 91 at 20 mA, and Commission Internationale de L'Eclairage coordinates almost remained at the same point from 5 to 60 mA.
