A Study on AIDS Self-Management Status and Its Influencing Factors.

Purpose: To investigate and analyse the status quo of the self-management of patients living with HIV/AIDS (PLWHA) and its influencing factors and to provide the basis for formulating intervention strategies.

Methods: In this cross-sectional study, 300 PLWHA who visited the Infection Center of Beijing Youan Hospital, Capital Medical University between September 2021 and December 2021 were enrolled using the convenience sampling method. Demographic characteristics and disease-related data were collected for each participant.

Association of systemic inflammation index with psoriasis risk and psoriasis severity: A retrospective cohort study of NHANES 2009 to 2014.

To investigate the association of systemic inflammation index (SII) with psoriasis risk and psoriasis severity. This is a retrospective cohort study based on data from the National Health and Nutrition Examination Survey database from 2009 to 2014. The psoriasis information was obtained from the questionnaire data, and the SII was calculated as neutrophil × platelet/lymphocyte.

Classification of diterpenoid alkaloids from Aconitum kusnezoffii Reichb. by liquid chromatography-tandem mass spectrometry-based on molecular networking.

Trace amounts of components in traditional Chinese medicine are considered pharmacological active substances used for treating many serious diseases. However, purifying all the trace substances and making clear their structures are not easy. In this context, high-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry based molecular networking was applied to investigate the chemical constituents of the roots of Aconitum kusnezoffii Reichb.

[Research progress on chemical constituents and pharmacological studies on root bark of Lycium barbarum].

Lycii Cortex, the dry root bark of Lycium barbarum(Solanaceae), is rich in chemical compositions with unique structures, such as organic acids, lipids, alkaloids, cyclopeptides and other components, and plays an important role in traditional Chinese medicine. It has the effect of cooling blood and removing steam, clearing lung and reducing fire. It is mainly used in the treatment of hot flashes due to Yin deficiency, hectic fever with night sweat, cough, hemoptysis and internal heat and diabetes.

[A new 9,19-cycloartane glycoside from Asplenium ruprechtii].

Chemical constituents of water extracts of Asplenium ruprechtii were investigated. Five compounds were isolated by silica gel, Sephadex LH-20 gel column chromatographies and preparative HPLC, and their structures were identified by various spectral analyses as aspleniumside G(1), trans-p-coumaric acid(2), trans-p-coumaric acid 4-O-β-D-glucoside(3), cis-p-coumaric acid 4-O-β-D-glucoside(4), and(E)-ferulic acid-4-O-β-D-glucoside(5). Among them, compound 1 is a new 9,19-cycloartane glycoside.

Design of a High-Efficiency and -Gain Antenna Using Novel Low-Loss, Temperature-Stable LiTi-(CuNb)O Microwave Dielectric Ceramics.

Microwave dielectric ceramics are vital for filters, dielectric resonators, and dielectric antennas in the 5G era. It was found that the (CuNb) substitution can effectively adjust the TCF (temperature coefficient of resonant frequency) of LiTiO and simultaneously increase its × ( and denote the quality factor and the resonant frequency, respectively) value. Notably, excellent microwave dielectric properties (ε (permittivity) ≈ 18.

An ultra-broadband terahertz metamaterial coherent absorber using multilayer electric ring resonator structures based on anti-reflection coating.

We propose a method for achieving THz ultra-broadband coherent absorption using the anti-reflection theory of metamaterials. The metamaterial absorber consists of a periodic array of electric ring resonators with a multilayered structure which form the desired refractive index dispersion and provide continuous anti-reflection over a wide frequency range. The destructive interference mechanism and resonance absorption of the absorber are determined by simulation analysis and numerical simulation.

Prognostic significance of the long noncoding RNAs in nasopharyngeal carcinoma: a systematic review and meta-analysis.

Background And Objective: Nasopharyngeal carcinoma (NPC) is a common head and neck malignancy. Despite recent advances in treatment, the prognosis, particularly for those at the advanced stages, remains poor. Moreover, the underlying genetic and molecular events have remained obscure so far.

Reverse transcription loop-mediated isothermal amplification for rapid detection of Japanese encephalitis virus in swine and mosquitoes.

Japanese encephalitis (JE) can infect many agriculturally important animals and humans, and has a high incidence in Asia. One of the natural hosts of the mosquito-borne JE virus (JEV) is domestic pigs, which act as amplifier hosts. Porcine infection results in fatal encephalitis, abortion, and stillbirth in pregnant sows, and hypospermia in boars.
