AIMS In chronic heart failure (CHF) patients, the ventilation (Ve) needed to eliminate metabolically produced CO(2) during exercise (i.e. the Ve/Vco(2) slope) is a strong prognosticator. Ve/Vco(2) slope determinants are the dead space-tidal volume (Vd/Vt) ratio and the arterial CO(2) partial pressure (Paco(2)). We aimed at defining the respective prognostic role of these two variables. METHOD...

Phase locked loop (PLL) is one of the most critical devices in modern electronic systems. PLLs are widely used as clock generator or frequency synthesis in communication systems, computers, radio and other electronic applications. Phase noise represents the phase variations of a PLL output signal and is the most important characteristic of PLLs because it reflects the stability of PLL systems. ...

BACKGROUND The aim of the present study was to compare the end-tidal O(2) pressure (PETO(2)) to end-tidal CO(2) pressure (PETCO(2)) in cardiac patients during rest and during 2 states of exercise: at anaerobic threshold (AT) and at peak. The purpose was to see which metabolic state, PETO(2) or PETCO(2), best correlated with exercise limitation. METHODS AND RESULTS Thirty-eight patients with l...

Researchers have connected the antioxidants in virgin coconut oil (VCO) to growing health benefits; however, little is known about hepatoprotective and antioxidant properties of VCO against oxidative stress liver damage brought on by smoking cigarettes. The research examined damage. Male Wistar rats were split into 4 groups: Group 1 (the control group) was fed rat pellets; 2 positive basic diet...

The lasted for 3 months, using 2 factor factorial com- pletely randomized design (CRD). first were type virgin coconut oil (VCO): LA (Original VCO) LT: (fermented VCO), second is fertilizer dosage: D0: 0 l ha-1; D1: 2,500 D2: 5,000 D3: 7,50...

The effect of virgin coconut oil (VCO) supplemented diet on sodium benzoate (SB) – induced neurotoxicity in male Wistar rats was investigated. Twenty (20) weighing 160-180g were divided into four (4) groups: Control which received 1ml normal saline, SB-treated; 200 mg/kg b.w, SB + Low Dose VCO-treated (SB 5% VCO mixed with 95g rat chow), and High (SB+ 15% 85g chow). brain processed for NRF-2, N...

BACKGROUND Ventilatory efficiency (VE/VCO(2) slope) and peak oxygen consumption (VO) provide robust prognostic information in patients with heart failure undergoing cardiopulmonary exercise testing (CPX). The purpose of this study is to assess the change in prognostic characteristics of CPX at different time intervals. METHODS AND RESULTS Seven hundred ninety-one subjects (74% male, mean age:...

Virgin Coconut Oil is an oil that processed from the extraction carried out fresh coconut fruit which in various ways, one of by using traditional methods, namely natural processing process, photosynthesis. The purpose making to take advantage potential nature agriculture increasing empowerment creative economy coastal communities during Covid-19 pandemic. method used socialization and training...

Electrical impedance tomography (EIT) merupakan salah satu metode citra yang didasarkan pada distribusi konduktivitas listrik suatu objek. Hasil rekonstruksi dengan teknik EIT sangat bergantung kemampuan sistem instrumentasinya (hardware) untuk menghasilkan data akurat. Salah bagian penting dalam membangun adalah sumber sinyal bolak balik biasa disebut Voltage-controlled oscillator (VCO). Pada ...
