Authors: Xiang Wu , Ji Bingjin , Jiang Yiqin , Xiang Han
Published: September 2022

Background

Currently, many studies have been published on the relationship between the gut microbiome and knee osteoarthritis. However, the evidence for the association of gut microbiota with knee osteoarthritis has not been comprehensively evaluated.

Objective

This review aimed to assess existing results and provide scientific evidence for the association of low-grade inflammation caused by gut microbiota disturbances with knee osteoarthritis.

Methods

This study conducted an extensive review of the current literature using four databases, PubMed, EMBASE, Cochrane Library and Web of Science before 31 December 2021. Risk of bias was determined using ROBINS and SYRCLE, and quality of evidence was assessed using GRADE and CAMADARES criteria. Twelve articles were included.

Results

Studies have shown that a high-fat diet leads to a disturbance of the gut microbiota, mainly manifested by an increase in the abundance of Firmicutes and Proteobacteria, a decrease in Bacteroidetes, and an increase in the Firmicutes/ Bacteroidetes ratio. Exercise can reverse the pattern of gain or loss caused by high fat. These changes are associated with elevated levels of serum lipopolysaccharide (LPS) and its binding proteins, as well as various inflammatory factors, leading to osteoarthritis (OA).

Conclusion

This systematic review shows that a correlation between low-grade inflammation caused by gut microbiota disturbances and severity of knee osteoarthritis radiology and dysfunction. However, there was a very small number of studies that could be included in the review. Thus, further studies with large sample sizes are warranted to elucidate the association of low-grade inflammation caused by gut microbiota disturbances with osteoarthritis, and to explore the possible mechanisms for ameliorating osteoarthritis by modulating gut microbiota.

Published: September 2022

He created many innovative works in many areas, such as religion, philosophy, art, social reform, women's upliftment, freedom, condemnation of superstitions, mercy, and humanity. In that way, his view on religion is admirable. Being born into a Brahmin clan, he was naturally inclined towards piety and religious thinking. At the same time, he also tried to look at them in a humanistic way. Because of that, he thought that there was a need for reform in society and religion to solve the woes of mankind. He directly condemned the superstitions traditionally practised by the Brahmins, which were not mentioned in the Vedas. He was very much attracted by Vedanta and sang many reconciliation songs mixed with Advaitha (dualistic) thoughts. However, he was deeply devoted to Goddess Parashakthi. Most of his Shakthi songs are composed in such a way, that the Almighty Shakthi should help the society prosper, for him to make revolutions, and to improve the lives of the poor. He records in many songs that the Goddess Shakti is present in his actions and words. Let us look at the composition of his Shakthi songs, which are arranged in such a way that he mentions that Shakthi is the cause of his activity, just as all life in the world needs a force to function.

Published: September 2022

Yeryüzünde meydana gelen dinamik hareketlerin tespit edilmesinde GNSS (Global Navigation Satellite System) sensörüne dayalı birçok konum belirleme yöntemi (Bağıl Kinematik, Gerçek Zamanlı Kinematik (RTK), Hassas Nokta Konumlama (PPP), Gerçek Zamanlı (RT)-PPP vb.) kullanılmıştır. Kullanılan bu yöntemler ikinci bir GNSS alıcısı, internet bağlantısı, uydu yörünge ve saat düzeltme bilgisi gibi harici parametreler gerektirir. Bu çalışmada herhangi bir harici parametreye ihtiyaç duymadan gerçek zamanlı (Real-Time) dinamik hareketleri doğrudan yakalayabilen VADASE (Variometric Approach for Displacement Analysis Stand-Alone Engine) yaklaşımının düşey yönlü dinamik davranışları belirleyebilme yeteneği incelenmiştir. Çoklu-GNSS gözlemlerine dayalı bu yöntem, zaman ve frekans alanında bağıl konum belirleme (RP) yöntemi referans alınarak PPP yöntemi ile karşılaştırılmıştır. Sonuçlara bakıldığında düşey dinamik hareketlerin baskın frekans değerlerinin üç yöntem için de aynı olduğu görülmüştür. Baskın frekansa karşılık gelen genlik değerlerinde ise deneylerde referans alınan RP yöntemine göre RT-VADASE yönteminde 1.6 mm ila 3.2 mm arasında değişmekteyken PPP yönteminde bu farklılık 1.1 mm ila 1.6 mm arasında değişmektedir. Ayrıca zaman alanında tüm deney durumlarına incelendiğinde RT-VADASE yönteminin PP-PPP yöntemine göre KOH değerleri arasında milimetre düzeyinde (1-2mm) küçük farklılık bulunmaktadır. Sonuçlar, RT-VADASE yaklaşımının anlık olarak düşey dinamik hareketleri doğru ve güvenilir bir şekilde tespit edebileceğini göstermektedir. Bununla birlikte, RT-VADASE yöntemi deprem, rüzgâr, trafik yükü gibi dinamik yüklerin, yapıda meydana getirebileceği etkiyi anlık olarak tespit etmek ve yapı sağlığını tehdit edebilecek durumlarda yapının hızlı tehlike değerlendirilmesi yapılarak insan hayatını tehlikeye düşürecek durumlarda erken uyarı sistemine entegre bir sensör olarak kullanılabileceği gösterilmiştir.

Novel Approaches to Oscillator Dynamic Linear Simulation Guarded by Circuit Fundamental Theory
Authors: ZHOU SHITI
Published: September 2022

This paper presents novel approaches to oscillator dynamic linear simulations. The simulations use the RF linear simulation software Genesys to simulate the integral transistor-based LC oscillators and the op-amp based Wien (RC) oscillator with the new criterion. The simulation approaches and criteria are designed based on a new oscillator linear theory, which treats oscillators as the energy-free two-port linear networks with the full characteristics of oscillators. The simulations are dynamic in order to be consistent with the dynamic oscillation buildup. The simulations are also linear to obey the circuit linearity constraint. The network response is controlled by the Thevenin source, where both E and R01 of the source are dynamic. This source is created from oscillator internal dynamic resonant energy. The generalized scattering parameter (S’) is used for the dynamic linear simulations. The simulations showed that the LC and Wien oscillators have the same characteristics at oscillation stable states, namely, the internal negative resistance (NR), internal inductive and capacitive impedances, positive phase slope, and negative net resistance of source loop.

Published: September 2022

Chronic wounds affect millions of people worldwide every year. An adequate assessment of a wound's prognosis is a critical aspect of wound care since it assists clinicians in understanding wound healing status, severity, triaging and determining the efficacy of a treatment regimen, thus guiding the clinical decision making. The current standard of care involves using wound assessment tools, such as Pressure Ulcer Scale for Healing (PUSH) and Bates-Jensen Wound Assessment Tool (BWAT), to determine wound prognosis. However, these tools involve manual assessment of a multitude of wound characteristics and skilled consideration of a variety of factors, thus, making wound prognosis a slow process which is prone to misinterpretation and high degree of variability. Therefore, in this work we have explored the viability of replacing subjective clinical information with deep learning-based objective features derived from wound images, pertaining to wound area and tissue amounts. These objective features were used to train prognostic models, that quantified the risk of delayed wound healing, using a dataset consisting of 2.1 million wound evaluations derived from more than 200,000 wounds. The objective model, which was trained exclusively using image-based objective features, achieved at minimum a 5% and 9% improvement over PUSH and BWAT, respectively. Our best performing model, that used both subjective and objective features, achieved at minimum an 8% and 13% improvement over PUSH and BWAT, respectively. Moreover, the reported models consistently outperformed the standard tools across various clinical settings, wound etiologies, sexes, age groups and wound ages, thus establishing the generalizability of the models.
Introduction To Data Preprocessing: A Review
Authors: Pratap Singh Aditya , Kaur Navneet
Published: September 2022

 This study begins with an overview of data preprocessing, focusing on real-world data challenges. Before any data analysis method begins, these are the first problems that have got to be understood and resolved. In this work, the author discusses data preprocessing, like standardization and normalization including feature scaling to more readily accomplish the data classification. Finding the most informative collection of features is the goal of preprocessing to boost the classifier's performance. Include standardization is for the most part expected to take out the impact of a few quantitative highlights estimated on various scales. Besides, feature scaling is used to normalize all different numeric numbers to properly scaled numbers. The point of this part is to help analysts in picking a fitting preprocessing procedure for information investigation. The basic preprocessing methods used for the characterization of information are then addressed in this section. Fitting Python features to various information applications will be shown as concrete examples at the end of each session.
