RESUMEN

BACKGROUND: Anabolic steroids, often referred to as anabolic-androgenic steroids, are steroidal androgens that include testosterone and other naturally occurring androgens, as well as synthetic androgens that are chemically linked to testosterone and have similar actions. MATERIAL AND METHODS: A cross-sectional study was conducted to evaluate the knowledge and awareness about anabolic-androgenic steroid (AAS) use and its side effects among adult gym participants in Jeddah. A total of 269 adults fulfilling the inclusion criteria were included. The questionnaire covered the demographics, attitudes, and behaviors associated with AAS use and consisted of single-response questions and four multiple-response questions. All statistical methods used were two-tailed with an alpha level of 0.05, considering significance if the p-value was less than or equal to 0.05. The overall awareness score was categorized as "poor" if the students' score was less than 60% of the overall score and "good" if the students' score was 60% or more. Descriptive analysis was done by prescribing frequency distributions and percentages for study variables, including the adult's personal data, reasons for going to the gym, and duration. RESULTS: This study shows a prevalence of 6.3% of adults' use of AAS, which was higher than in some regions in Saudi Arabia. The largest age group that uses AAS, according to this study, is 26-45 years old. A total of 185 (68.8%) were males, and a total of 185 (68.8%) were university graduates. The most reported reasons for going to the gym included fitness (63.2%), muscle building (52.8%), entertainment (39.4%), and weight loss (37.9%). 94.4% of people think that anabolic steroids are harmful to the body, and 80.3% know that misuse of anabolic steroids may lead to problems with the kidneys and liver. 75.1% of male adults and 76.8% of university graduates had good knowledge and awareness. The internet is the most common source of information. CONCLUSION: Our study provides clear evidence that there is a high awareness of AAS and its side effects and a high prevalence of its use among male gym participants in Jeddah. The use of AAS is a national problem that the authorities need to act on. There is a strong need for health policy reforms to reduce the rise of AAS use among young adults.

RESUMEN

Complex networks have been programmed to mimic the input and output functions in multiple biophysical algorithms of cortical neurons at spiking resolution. Prior research has demonstrated that the ineffectual features of membranes can be taken into account by discrete fractional commensurate, non-commensurate and variable-order patterns, which may generate multiple kinds of memory-dependent behaviour. Firing structures involving regular resonator chattering, fast, chaotic spiking and chaotic bursts play important roles in cortical nerve cell insights and execution. Yet, it is unclear how extensively the behaviour of discrete fractional-order excited mechanisms can modify firing cell attributes. It is illustrated that the discrete fractional behaviour of the Izhikevich neuron framework can generate an assortment of resonances for cortical activity via the aforesaid scheme. We analyze the bifurcation using fragmenting periodic solutions to demonstrate the evolution of periods in the framework's behaviour. We investigate various bursting trends both conceptually and computationally with the fractional difference equation. Additionally, the consequences of an excitable and inhibited Izhikevich neuron network (INN) utilizing a regulated factor set exhibit distinctive dynamic actions depending on fractional exponents regulating over extended exchanges. Ultimately, dynamic controllers for stabilizing and synchronizing the suggested framework are shown. This special spiking activity and other properties of the fractional-order model are caused by the memory trace that emerges from the fractional-order dynamics and integrates all the past activities of the neuron. Our results suggest that the complex dynamics of spiking and bursting can be the result of the long-term dependence and interaction of intracellular and extracellular ionic currents.

RESUMEN

The multiple activities of neurons frequently generate several spiking-bursting variations observed within the neurological mechanism. We show that a discrete fractional-order activated nerve cell framework incorporating a Caputo-type fractional difference operator can be used to investigate the impacts of complex interactions on the surge-empowering capabilities noticed within our findings. The relevance of this expansion is based on the model's structure as well as the commensurate and incommensurate fractional-orders, which take kernel and inherited characteristics into account. We begin by providing data regarding the fluctuations in electronic operations using the fractional exponent. We investigate two-dimensional Morris-Lecar neuronal cell frameworks via spiked and saturated attributes, as well as mixed-mode oscillations and mixed-mode bursting oscillations of a decoupled fractional-order neuronal cell. The investigation proceeds by using a three-dimensional slow-fast Morris-Lecar simulation within the fractional context. The proposed method determines a method for describing multiple parallels within fractional and integer-order behaviour. We examine distinctive attribute environments where inactive status develops in detached neural networks using stability and bifurcation assessment. We demonstrate features that are in accordance with the analysis's findings. The Erdös-Rényi connection of asynchronization transformed neural networks (periodic and actionable) is subsequently assembled and paired via membranes that are under pressure. It is capable of generating multifaceted launching processes in which dormant neural networks begin to come under scrutiny. Additionally, we demonstrated that boosting connections can cause classification synchronization, allowing network devices to activate in conjunction in the future. We construct a reduced-order simulation constructed around clustering synchronisation that may represent the operations that comprise the whole system. Our findings indicate the influence of fractional-order is dependent on connections between neurons and the system's stored evidence. Moreover, the processes capture the consequences of fractional derivatives on surge regularity modification and enhance delays that happen across numerous time frames in neural processing.
