Diagnosis and management of hypertension understanding imperative role of various biomarkers

  As hypertension, almost 90% of cases of hypertension with an unknown origin called essential hypertension, continue to be one of the most important risk factors for various fatal health conditions, its early diagnosis using trustworthy biomarkers to predict, diagnose, and monitor the therapeutic progress of hypertension is proving to be of utmost importance for the preventive as well as curative purpose of various health hazards. A rise in the activity of biochemical markers of endothelial dysfunction and blood lipids, notablyLow-density lipoprotein (LDL) andverylow-density lipoprotein(VLDL)measurements, and inflammation markers including C-reactive protein(CRP), cytokines, and adhesion molecules are linked to the development of hypertension. Growth and differentiation factor-15, red cell distribution width, uric acid, creatinine, inflammatory markers including interleukin-6, angiopoietins, and microRNAs are prognostic indicators in individuals with pulmonary arterial hypertensio...

Antiproliferative and pro-apoptotic properties against colon carcinoma cell line of the marine sponge haliclona sp. From poblacion, kauswagan, lanao del norte, Philippines

  Marine sponge Haliclona sp. was examined for its anticancer potential focusing on the antiproliferative and pro-apoptotic properties against HCT116 (colon) cancer cell line. The 16 fractions obtained from Haliclona sp. were subjected to antiproliferative and pro-apoptotic evaluation via MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay and Caspase-Glo 3/7 assay, respectively, at 30 μg/mL concentration. Fractions 10, 13, 14, and 15 exhibited a significant decrease (p < 0> 50�ll viability) against HCT116. Only fraction 8 showed a significant increase (p < 0.05) in relative light unit (RLU) and fold change (FC) (1809.78 and 2.42), more than two times larger, compared to the negative control (754.89 RLU and 1.00 FC). This result demands further study on fraction 8 to identify and characterize the structure of the compounds responsible for its bioactivity and hence could be a source of drug leads. https://jmpas.com/abstract/1169

A preliminary study on the effects of human microRNAs on gut microbiota

  MicroRNAs (miRNAs) play a key role in disease manifestation, metabolic processes and immune regulation and modulation of the host. MiRNAs can be found in abundance in fecal samples of humans and are present in intracellular, extracellular fluid and extracellular vesicles. Abundance of miRNAs is found to be in ileal lumen as compared to the colon, whereas gut microbiota is more in colon, not in ileum. Still the effect of miRNA is found where the gut microbiota is more, which is by co-localizing with the nucleic acid of the bacteria. Some human miRNAs can regulate the non-coding RNAs in bacterial species like Escherichia coli and Fusobacterium nucleatum by entering into the bacterial cell in the intestine. By repressing the activity of the noncoding RNAs of intestinal bacterial species, human miRNAs bring about the increase or decrease in population of gut microbiota. With the change in the population of the certain microbiota species in the intestine, the host becomes more suscept...

Comparison of ALEXNET and GOOGLENET convolutional neural network models to detect obstructive sleep apnea using single-channel electrocardiogram

  Obstructive Sleep apnea (OSA) is a type of sleep disorder caused due to respiratory collapse during sleep. This sleep disorder generally goes undiagnosed and neglected. Severe OSA may cause arrhythmia, sudden death, high blood pressure, and other cardiac anomalies. Polysomnography (PSG) is the most popular gold standard used by many researchers to detect OSA. PSG required a well-equipped sleep laboratory and skilled persons to record multi- channel signals to detect OSA. PSG is a complex and expensive method and hence motivated to conduct the research using single-channel electrocardiogram (ECG). An automatic detection method of OSA using single-channel ECG in Convolutional Neural Network (CNN) takes less computing time as feature engineering does not require. This paper focuses on the automatic detection of OSA using ECG with two different deep CNN architectures AlexNet and GoogLeNet transfer learning. The apnea ECG datasheet is used for assessing the method proposed. The state ...

Toxicity test of clove leaf extract compared to clove flower extract (syzygium aromaticum) as aedes aegypti linnaeus larvacide

  Dengue Hemorrhagic Fever (DHF) is an epidemic disease. In early 2019 the World Health Organization (WHO) determined it as a potential threat. Prevention efforts have been made in biology, chemistry, and behavior. However, the use of chemicals that become instant measures has a negative impact on the occurrence of mosquito resistance and environmental pollution. Natural materials are alternative solutions as natural potentials that are easy, cheap, and safe for human health and environmental health. Cloves are Indonesia's natural potential which contains eugenol, saponins, flavonoids, and tannins which have the potential as active ingredients for Aedes aegypti larvicidal.

Nano-crystals a comprehensive review on formulation and application perspectives

  A majority of recently invented medications have been discovered to be poorly water-soluble and cause delays in the formulation and development of dosage forms. Solubility has been a major problem for BCS classes II and IV. As a result, nanotechnology may be useful in resolving the solubility problem. This review will cover Nanocrystals, as well as the numerous methodologies employed in their formulation and their application. Nanocrystals are nanometre-sized drug particles of a poorly water-soluble compound. They are distinct from polymeric nanoparticles in that they are entirely made up of the drug. Nanocrystals can be implemented to increase the rate of dissolution and saturation solubility of active pharmaceutical ingredients. Milling, high-pressure homogenization, precipitation, and combination methods such as Nanoedge andSmartCrystal, are among the approaches available for its formulation. The transition of nanocrystals into final formulations, as well as future nanocrystal...
