The objective of this study was to compare FMD data and sensations of pain and numbness using three levels of occlusion cuff pressures commonly used for FMD assessment in healthy adults. A within-subject design was conducted in 12 healthy adults aged 20-40 years. FMD was measured using brachial artery Doppler ultrasound at three different occlusion pressures: 25 and 50 mmHg above systolic blood pressure (SBP) and 200 mmHg. Pain and numbness were recorded using the Numeric Pain Rating Scale and the Visual Analog Scale, respectively, at baseline and every minute during the 5-minute occlusion and 3 minutes after cuff deflation. The results showed that %FMD and mean blood flow velocity after using cuff pressure at 25 mmHg above SBP (10.11 ± 2.58% and 11.52 ± 3.96 cm/s) were comparable to those of 50 mmHg above SBP (10.08 ± 2.70% and 12.54 ± 4.31 cm/s) and at 200 mmHg (10.15 ± 2.74% and 12.28 ± 4.30 cm/s) (all P >0.05). The pain intensity was significantly greater at 200 mmHg compared to 25 mmHg at the first, second, and fourth minutes during occlusion (all P <0.05). The numbness scale was not different among the three pressure conditions. In conclusion, the minimum occlusion pressure above SBP by 25 mmHg generated an insignificant FMD response compared to the other two cuff pressures, caused minor pain, and may be the favorable pressure for determining endothelium-dependent FMD in healthy Thai adults.","PeriodicalId":471315,"journal":{"name":"Natural and Life Sciences Communications","volume":"66 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141922564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The escalation of cases in Southeast Asia, notably Indonesia, is a matter of considerable concern. Timely identification of DENV infection remains imperative for efficient disease management. The non-structural protein-1 (NS1), distinguished by its heightened immunogenicity and early detectability during infection, stands as a pivotal target for diagnostic modalities. The current investigation delves into the exploration of B-cell epitopes within Indonesian DENV NS1 protein isolates, with the overarching objective of enhancing the sensitivity and specificity of early detection systems, such as the Rapid Diagnostic Test (RDT). This study has successfully delineated five B-cell epitopes that exhibit conservation across DENV serotypes within Indonesian isolates (accessions number: QBB90021.1, QBE90252.1, QBB90023.1, and UDW38833.1). These epitopes were discerned through comprehensive screening leveraging the IEDB platforms. Noteworthy variations in antigenicity, allergenicity, and toxicity profiles were observed among these identified epitopes. Molecular docking analysis substantiated a robust binding affinity between the predicted epitope and the B-cell receptor. The ensuing in silico protein-peptide docking analyses offer valuable insights into potential B-cell epitopes on the Indonesian DENV NS1 protein. The identified epitopes, particularly the SQHNYRPGY epitope characterized by its antigenic potency and non-allergenic attributes, hold promise for advancing the development of sensitive and specific RDTs tailored for DENV detection in the Indonesian context. However, it is imperative to underscore the requisite for subsequent experimental validation to affirm the efficacy of these epitopes in diagnostic applications.","PeriodicalId":471315,"journal":{"name":"Natural and Life Sciences Communications","volume":"32 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141813282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Protein-DAMPs are abundant biomolecules that could potentially be a novel biomarker for pathology. Myocardial ischemia injury is a causative process for ischemic heart disease, which is now the leading cause of global deaths. Early diagnosis is necessary to save patient lives, so the discovery of new early cardiac biomarkers is crucial. Here, we examined the protein-DAMPs expression in ischemic buffer collected from adult ventricular myocytes cells subjected to various timepoints of simulated ischemia (sI). Adult ventricular myocytes cells (AC-16) were subjected to sublethal simulated ischemia (sI) by treatment with ischemic buffer for 5, 10, 20, and 30 minutes (I5, I10, I20, and I30, respectively). After simulated ischemia was achieved, the ischemic buffer was collected and determined for proteins profiling by Shotgun proteomics approach. Cell viability was reduced in a time dependent manner in ischemia. Targeted proteomics reveals 21 proteins found to highly increase in early ischemic injury and can still be detected until 30 minutes of ischemia. Lactotransferrin (LTF) was determined to be the protein with the greatest impact, exhibiting both fast and sustained release throughout the whole study time. The present study identified the protein damage associated molecular pattern (DAMPs) released specifically from ischemia-induced cardiomyocytes injury, which could potentially be candidates to be early biomarkers for myocardial ischemic injury. Further studies should be focused on in vivo validation of potential protein markers that could be used in practical clinical applications.","PeriodicalId":471315,"journal":{"name":"Natural and Life Sciences Communications","volume":"110 S1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141683467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work describes the analysis of the morphological properties of Poly (vinyl alcohol) (PVA)/Gelatin contained Indonesian carbonated hydroxyapatite (CHA) abalone nanoparticle scaffold by electrospun nanofiber. CHA nanoparticles were produced using a co-precipitation method, and nanofibrous PVA/Gelatin/CHA 5 wt% scaffold was fabricated by electrospinning. The synthesized CHA produced the same condition as B-type CHA, ensured by Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffractometer (XRD), and differential scanning calorimetry (DSC), and energy-dispersive X-ray spectroscopy (EDS) tests. The morphological properties of PVA/Gelatin/CHA are analyzed using Scanning Electron Microscopy (SEM). The SEM image indicated that PVA/Gelatin nanofiber tended to have a fine morphology without beads. The agglomeration of the PVA/Gelatin/CHA 5 wt% nanofiber scaffold can be neglected because it is still on the sub-micron scale (1 μm–100 nm). Moreover, adding CHA 5 wt% in the PVA/Gelatin matrix decreased the average fiber diameter. The diameter fiber results are within the fiber diameter range (100–450 nm) in native bone ECM. Therefore, PVA/Gelatin/CHA 5 wt% has the potential to serve as an alternative scaffold material for BTE application.","PeriodicalId":471315,"journal":{"name":"Natural and Life Sciences Communications","volume":"34 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141355578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores complex drivers behind shunning hospital births using focused rural ethnography. Between October and November 2023, this qualitative study interviewed 40 participants including pregnant women, postpartum women, and their relatives across 5 villages in Bokeo Province regarding barriers to hospital births. Open-ended discussions aimed to elucidate motivations and barriers embedded in their decision to avoid formal delivery care, despite mortality awareness. Transcriptions from Lao were translated to Thai, maintaining cultural nuances. Thematic analysis identified patterns in women’s attitudes and barriers to hospital childbirth. A collaborative coding process revealed constraints on access, affordability, and autonomy, explaining why vulnerable groups often forego hospital births despite risks. The result founded that prohibitive transportation deficiencies including impassable roads, exorbitant driver fees and unreliable conveyance options were primary obstacles. Prohibitive direct and indirect costs compounded struggles for impoverished families. Restrictive traditions persisted among certain ethnicities. Discrimination fears and hospital foreignness also provoked wariness among a minority. Multidimensional geographical, financial and sociocultural barriers intersect to obstruct rural groups from accessible emergency obstetric care in Laos. Infrastructural strengthening, financial protection and public education can relieve these pronounced constraints denying the marginalized realization of maternal health rights.","PeriodicalId":471315,"journal":{"name":"Natural and Life Sciences Communications","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141375823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Artificial Intelligence (AI) tools are used to analyze the interaction between phytoconstituent and silver ion to find the capping and nanoparticle fabricating phytoconstituents. Ethanolic extract was added to silver nitrate solution and irradiated under sunlight until the formation of silver nanoparticles. These particles were sedimented, characterised by spectral technique and biological activity was measured. Finally, a Computational simulation algorithm was used to visualize the interactions of phytoconstituent and silver nanoparticles. Ultra Violet (UV)-visible spectrum revealed a visible peak at 420nm in the brownish solution, Dynamic Light Scattering (DLS) size of 54.7nm, spherical crystalline morphology of the nanoparticle by Transmission Electron Microscope (TEM) and X-Ray Diffraction (XRD) analysis. The synthesized silver nanoparticle antagonised Escherichia coli, and Bacillus cereus and showed the Minimum Inhibitory Concentration (MIC) of 65 µg/mL, and 78 µg/mL respectively and Minimum Bacterial Concentration (MBC) of 52.5 µg/mL for B.cereus and 61.5µg/mL for E.coli.

The Face-centered Central Composite Design (FC-CCD), involving two factors with three levels each (pressure of 200, 400, and 600 MPa, and time of 5, 10, and 15 min), was applied to investigate two response variables (total phenolic and flavonoid content).

Compared to other pressures (400 and 600 MPa) at common processing time (15 minutes), 200 MPa recorded higher TPC and TFC with differences of 25.71% to 30.92% and 13.78% to 14.19%, respectively. A verification step revealed that HPP-KH at 200 MPa for 15 minutes yielded a TPC of 15.278 ± 0.525 mg GAE/100 g and a TFC of 38.274 ± 1.980 mg RE/100 g, indicating the precise accuracy of the quadratic modeling.

However, no previous study has investigated the combined effects on perioral soft tissue, which includes the upper lip (UL), lower lip (LL), and chin projection. We explored the impact of OJ severity and skeletal divergence on the perioral soft tissue. Lateral cephalograms of 133 untreated skeletal Class II adult patients were allocated into three categories according to the degree of skeletal divergence: hypodivergence (Hypo), normodivergence (Normo), and hyperdivergence (Hyper). Furthermore, OJ was classified as normal OJ (NOJ), moderately excessive OJ (MEOJ), and severely excessive OJ (SEOJ). A matrix of skeletal divergence and OJ variables produced the following groups: NOJ-Hypo, MEOJ-Hypo, SEOJ-Hypo, NOJ-Normo, MEOJ-Normo, SEOJ-Normo, NOJ-Hyper, MEOJ-Hyper, and SEOJ-Hyper. The skeletal, dental, and soft tissue parameters were measured. Statistical analyses showed that increased hyperdivergence and OJ severity corresponded with a more retruded mandibular perioral soft tissue (MPST), except for the Pog’ in the SEOJ-Hypo group, which was insignificantly more prominent than the MEOJ-Hypo group. Unlike the LL, the UL was similar among the groups. Multiple regression indicated that greater OJ and skeletal divergence significantly influenced MPST retrusion and increased vermilion lower lip thickness (VLLT) while independently affecting deeper mentolabial sulcus depth (MSD) and a more obtuse lip-chin-throat angle (P < 0.05). The effect of OJ was most significant at the LL and gradually decreased down to the chin; conversely, divergence increased downwards. The SEOJ-Hyper group displayed the greatest retruded MPST, thickest VLLT, and deepest MSD, which highlighted the combined effect of OJ and divergence.","PeriodicalId":471315,"journal":{"name":"Natural and Life Sciences Communications","volume":"45 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140969394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
