This in vitro study aims to compare the dimensional accuracy of dental implants in casts obtained from open tray splinted implant impression techniques using two different splinting materials.
Methods and Material: A mandibular acrylic model with four implant analogues was used as a reference model. Open tray impression copings were attached to the implant analogues and were splinted using two different materials. Group I-splinted with pattern resin, sectioned and re-joined and Group II- splinted with light cure tray material. Eight polyether impressions were made for each group and poured in type IV dental stone. The casts retrieved from each group were three-dimensionally analysed using coordinate measuring machine with 0.001 mm accuracy. A one-way ANOVA and post hoc test was done to calculate the statistically significant difference between the groups.
Results: The present study revealed no significant difference in the inter-implant distances obtained from pattern resin splinted group, whereas, significant difference in z-axis was found in light polymerising tray resin splinted group when compared to the values obtained from the reference model.
Conclusions: Casts obtained from splinting the impression copings using pattern resin before making implant impression were found to be more accurate than splinting with light cure tray material.

Published: July 2023

In this research, a wideband bi-directional pattern antenna implemented by a circular monopole encircled with an enforced-radiation circular ring incorporated with inversed L-shaped stub is designed to operate over the mid-band of 5G applications ranging from 2 to 6 GHz. It is contrived of a copper overlaid on FR4 substrate with relative permittivity of 4.3 and height of 1.6 mm. This proposed antenna is fed by a 50-ohm coplanar waveguide, which is printed on the same side of the radiated circular monopole. To further enrich the impedance matching, a pair of etched slots is added-on the ground plane near the fed line to reduce the return loss. In the study, the initial parameters are theoretically worked out, and then simulation is then performed by using an electromagnetic solutions tool to numerically discover the set of solution parameters. From the simulation results, this proposed antenna offers the |S11|<–10 dB covered the operating frequency running from 1.79 to over 8 GHz with fractional bandwidth 126.90 % and 1.74 to 7.07 GHz with fractional bandwidth 101.04 % for the simulation excluded and included SMA, respectively. It provides a linear polarization with total efficiency better than 81.5 %. After that, an antenna prototype with compact dimensions of 45×45×0.6 mm3 was fabricated and testified to validate the simulation results. The measurement results provide a stability bi-directional pattern with peak gain of 5.54 dBi covering a 10 dB return loss bandwidth of 118.5 % (1.93–7.54 GHz). Simulated |S11|, 2D radiation pattern and gain are reasonably in good agreement with experimental results. Furthermore, this proposed antenna is compared with the current compact, wideband and 5G antenna to indicate its prospective for the interested bands

Published: July 2023

Abstract:
Dry Blood Spots (DBS) have been used in combination with liquid chromatography-mass
spectrometry for targeted proteomics to identify sensitive and specific novel biomarkers. DBS presents
several advantages over other traditional blood sampling methods. This review discusses the
past, present and future of the technology, focusing on studies with clinical and population relevance.
Arguments for and against DBS are presented by discussing technological advances, particularly those
related to Mass Spectrometry (MS) and Multiple Reaction Monitoring (MRM), sample preparation issues,
disease biomarkers, pharmacokinetics, and pharmacodynamics. There will be a focus on proteomic
studies that rely on DBS as a sampling method. In this context, numerous studies on the diagnosis
and treatment of several diseases. To date, proteomic reports of studies using DBS have shown that
DBS can facilitate diagnosis and prognosis. DBS offers several advantages that make it a viable option
for many fields. Moreover, some of its disadvantages can be easily overcome through automation to
increase reproducibility and reduce protocol variability and standardization of parameters such as the
volume of sample used. Within this context, here we propose to review the advantages and disadvantages
of using DBS for blood proteomics and provide an understanding of how current DBS-based
protocols are being conducted for future standardization and protocol optimization.
