Assessment of Cardiorespiratory Interactions During Spontaneous and Controlled Breathing: Linear Parametric Analysis

In this work, we perform a linear parametric analysis of cardiorespiratory interactions in bivariate time series of heart period (HP) and respiration (RESP) measured in 19 healthy subjects during spontaneous breathing and controlled breathing at varying breathing frequency. The analysis is carried out computing measures of the total and causal interaction between HP and RESP variability in both time and frequency domains (low- and high-frequency, LF and HF). Results highlight strong cardiorespiratory interactions in the time domain and within the HF band that are not affected by the paced breathing condition. Interactions in the LF band are weaker and prevalent along the direction from HP to RESP, but result more influenced by the shift from spontaneous to controlled respiration

Rekomendasi dari hasil penelitian ini adalah (1) pengusaha UKM mulai membawa investor sebagai pemodal dengan perhitungan bisnis yang disepakati (2) pengusaha UKM yang menggunakan kebijakan modal kerja konservatif harus berani menggunakan dana eksterna

Assessment of Cardiorespiratory Interactions During Spontaneous and Controlled Breathing: Non-linear Model-free Analysis

In this work, nonlinear model-free methods for bivariate time series analysis have been applied to study cardiorespiratory interactions. Specifically, entropy-based (i.e. Transfer Entropy and Cross Entropy) and Convergent Cross Mapping asymmetric coupling measures have been computed on heart rate and breathing time series extracted from electrocardiographic (ECG) and respiratory signals acquired on 19 young healthy subjects during an experimental protocol including spontaneous and controlled breathing conditions. Results evidence a bidirectional nature of cardiorespiratory interactions, and highlight clear similarities and differences among the three considered measures

Uji Efektivitas Ekstrak Melati (Jasminum Sambac) Pada Penyembuhan Luka Insisi Kelinci (Oryctolagus Cuniculus)

: Flowers and leaves of jasmine (Jasminum sambac) have chemical substances that contain phytoconstituents such as alkaloids, glycosides, saponins, terpenoids and flavonoids. Flavonoid, an antioxidant, plays some importnat roles in wound healing due to their antibacterial effect. This study aimed to determine the effectiveness of jasmine leaf extract on incision wound healing in rabbits. This was an experimental study using three rabbits as test subjects. Wounds of 0.3 cm depth, 5 cm length, and 0.5 cm widened at both ends of the wound were made on the right and left sides of the back. Incised wound on the left side was treated with jasmine leaf extract ointment meanwhile the wound on the right side was untreated and was covered only with sterile gauze. Wounds were observed for two weeks to evaluate the changes of macroscopical length. The results showed that wounds treated with jasmine leaf extract ointment shrank and their edges united with the surrounding tissues faster than the untreated wounds. Conclusion: Jasmine leaf extract ointment accelerated incised wound healing in rabbits

Feasibility of Ultra-short Term Complexity Analysis of Heart Rate Variability in Resting State and During Orthostatic Stress

In this work, we study ultra-short term (UST) complexity of Heart Rate Variability (HRV) and its agreement with analysis of standard short-term (ST) HRV recordings obtained at rest and during orthostatic stress. Conditional Entropy (CE) measures have been computed using both a linear Gaussian approximation and a more accurate model-free approach based on nearest neighbors. The agreement between UST and ST indices has been compared via statistical tests and correlation analysis, suggesting the feasibility of exploiting faster algorithms and shorter time series for detecting changes in cardiovascular control during various states

FILOGENI MOLEKULER BAKTERI DARI MEDIA PEMELIHARAAN ROTIFER YANG DIBERI OLAHAN LIMBAH IKAN SEBAGAI SUMBER NUTRISI

This study aims to identify and construct molecular phylogeny of an isolate bacteria from culture media of rotifer Brachionus rotudiforis supplied with processed fishery waste feed as nutritional source. The use of fish waste-based food for rotifer showed positive effects on growth and nutrient content of the rotifers. Genomic DNA of the isolate bacteria BRLI- 01 was extracted and the 16S rRNA gene was amplified using primers (8F and 1492F) and further sequenced using Sanger sequence technique. The 16S rRNA gene was analysed using SeqScanner® and MEGA® followed with BLAST (Basic Local Alignment Search Tool) analyses in the NCBI (National Centre for Biotechnology Information). Amplification result of 16S rRNA gene bacteria s NCBI site as a reference for identification and phylogeny of bacterial species. BRLI-01 was successfully cultured on rotifer rearing media. The results of the 16S rRNA gene amplification of the isolate bacteria showed a DNA band with a length of 1400 bp. The BLAST result on the NCBI showed that the isolate bacteria BRLI-01 had a percent identity (98.46%) and is in the same phylogony branching position with Vibrio rotiferianus Keywords: Rotifers, Bacteria, Fish waste, 16S rRNA Genes, Phylogeny identificatio
