Abstract Objectives The variability in the time intervals between heartbeats, known as heart rate (HRV), serves a reflection of intricate interplay sympathetic and parasympathetic neural systems. While potential asymmetric effects left right branches vagus nerve remain uncertain, this study aims to investigate impact unilateral, bilateral, atropine interventions on HRV parameters choline levels within cardiac tissue. Methods 40 male adult Wistar albino rats were randomly assigned five groups...
Anesthetics are often used in animal experiments to achieve immobilization and relieve pain. However, many anesthetics can alter the dynamics of cardiovascular systems. We aimed compare effects two frequently agents on heart rate variability (HRV) parameters mice.This observational study was performed between May June 2014 21 male BALB/c mice aged 16-20 weeks. The animals were divided into three groups: pentobarbital (P), (n = 7); pentobarbital+fentanyl (P+F), ketamine+xylazine (K+X), 7)....
There are several ways to assess complexity, but no method has yet been developed for quantitatively calculating the 'loss of fractal complexity' under pathological or physiological states. In this paper, we aimed evaluate complexity loss using a novel approach and new variables from Detrended Fluctuation Analysis (DFA) log-log graphics. Three study groups were established approach: one normal sinus rhythm (NSR), congestive heart failure (CHF), white noise signal (WNS). ECG recordings NSR...
The thermodilution method has been widely used to estimate cardiac output by injecting a cold solution into circulating blood. It is uncertain if radial heat transfer from the vascular/cardiac wall injectate can cause inaccurate results with this method. In study, we have introduced physical experimental model of without recirculation solution. To test accuracy method, setup included an aluminum tube allow transfer. Variations following parameters were conducted: (i) real flow rate, (ii)...
Abstract Anxiety is a common issue among university students, many of them experience anxiety, depression, and stress during their school life. This study aimed to compare the acute physiological responses students divided into two groups according perceived anxiety levels (positive test PTA+, negative PTA-). Heart rate variability (HRV) electrodermal activity (EDA) were used assess stress. Thirty-one healthy volunteers participated in study. Participants completed assessments, including...
Giriş ve Amaç: Konjestif kalp yetmezliği (KKY) atriyal fibrilasyon (AF) hastalarında ani kardiyak ölüm, bu hastalardaki ölümlerin önemli bir kısmını oluşturur. Ani ölüm riskini tahmin etmek için birçok parametre kullanılmaktadır. Ancak atım hızı değişkenliği (KHD), yüksek gücü, düşük maliyet girişimsel olmayan ölçüm yöntemi olarak öne çıkmaktadır. Bazı KHD parametreleri, KKY bağımsız prognostik bilgi sağlamıştır. Biz de çalışmada normal sinüs ritme sahip bireylerde, konjestif AF...
Amaç: Barsak mikrobiyatası ile beyin arasında iki yönlü bir ilişki olup özellikle travmatik hasarı (TBH) sonrası hasarda oksidatif stres ve enflamatuvar aşama önemli role sahiptir.Barsakta oluşan patoloji bu hasarın tedavisinde problem oluşturmaktadır.Probiyotikler (PB) bunu düzenleyerek gliozisi azaltabilme potansiyelindedir.Bu çalışmada sıçan modelinde TBH oluşturulup PB için olası etki
Abstract Aim The dorsal nerve of the penis (DNP) is terminal branch pudendal which responsible for somatic innervation penis. This study aims to outline any direct role DNP in hemodynamics erection histologically and physiologically. Materials Methods Fifteen Wistar albino rats were sorted into electrical activity ( n = 6), intracavernous pressure 4), control 5) groups. was electrostimulated simultaneous changes smooth muscle recorded. Penile tissues collected, fixed, sectioned, slides...
Objective: Heart rate variability (HRV) is used to evaluate the autonomic activity of heartbeat. This study aimed investigate effects cholinomimetic drugs cytidine diphosphate-choline (CDP-choline) and choline, on short-term HRV parameters. Materials Methods: Animals were randomized into three groups; control (0.9% NaCl), choline (100 mg/kg), CDP-choline (400 mg/kg). Electrocardiography recordings obtained for 45-minutes after treatments with 15-minutes intervals. analyses total level...
A BSTRACT Objective: Anesthetic agents, which are used in appropriate doses for the application of experimental procedure animals, relieve pain when applied sufficient amounts as well muscle relaxation. However, many anesthetics can alter dynamics neuromuscular systems. We aimed to compare effects two frequently anesthetic agents on electromyographic parameters rats. Materials and Methods: This study was performed male Wistar albino rats aged 22–24 months. The animals were divided into...
