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

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

ESTIMASI KANDUNGAN KARBON SERASAH DAUN MANGROVE RHIZOPHORA spp. DI HUTAN MANGROVE DESA WORI, KECAMATAN WORI, KABUPATEN MINAHASA UTARA

Mangroves play an important role in supporting life in coastal and marine areas. As plants that live in marine and land areas, mangrove forests transfer various kinds of nutrients both on land and into the sea. Decreasing area of mangrove forests leads to a decrease in mangrove litter production. Mangrove litter has a function as a carbon sink and storage. The purpose of this study was to determine the percentage of carbon content (C) and estimate the amount of carbon stored in the leaf litter of mangrove Rhizophora spp., in the mangrove forest of Wori Village, Wori District, North Minahasa Regency. The Litter-trap method (litter trapping net) was used in this study. Litter collection was carried out for 28 days in 12 litter-traps measuring 1x1 m2. All litters trapped in the litter-trap were weighed in their wet and dry weight, then analyzed in the laboratory to determine the carbon content. Based on the results of the analysis, the total average percentage of carbon content in mangrove litter 25.93% C, and from the estimation results, the average carbon content (C) in the litter is 19.99 tons/ha/year. Keywords: Mangrove, Litter, Litter-Trap, Carbon Content, Wori Village ABSTRAK Mangrove merupakan ekosistem yang berperan penting dalam mendukung kehidupan di wilayah pesisir dan kelautan. Sebagai tumbuhan yang hidup di wilayah laut dan darat, hutan mangrove mentransfer berbagai macam nutrien baik ke darat maupun ke laut. Berkurangnya luasan hutan mangrove menyebabkan produksi serasah mangrove juga berkurang. Serasah mangrove memiliki fungsi sebagai penyerap dan penyimpan karbon.Adapun tujuan dari penelitian ini yaitu untuk mengetahui persentase kandungan karbon (C) dan Mengestimasi jumlah karbon yang tersimpan pada daun serasah mangrove Rhizophora spp., di hutan mangrove Desa Wori, Kecamatan Wori Kabupaten Minahasa Utara.Pengambilan sampel pada penelitian ini menggunakan metode Litter- trap (jaring penangkap serasah). Pengumpulan serasah dilakukan selama 28 hari dalam 12 Litter-trap yang berukuran 1x1 m2 . Seluruh serasah yang terperangkap di dalam litter-trap di timbang berat basah dan berat keringnya, kemudian dilakukan analisis di Laboratorium untuk mengetahui kandungan karbon. Berdasarkan hasil analisis didapatkan total rata-rata persentase kandungan karbon serasah mangrove yakni sebesar 25,93 % C, serta dari hasil estimasi didapatkan rata-rata kandungan karbon (C) pada serasah sebesar 19,99 ton/ha/tahun.
