Comparison of Quadratus Lumborum Block and Transversus Abdominis Plane Block for Postoperative Pain Management
Authors: Whiteley Kristina Alexis 
Published: August 2024

Enhanced recovery after surgery (ERAS) protocols have been developed to promote rapid recovery of patients who undergo certain major surgeries, throughout the perioperative continuum, with a variety of interventions. Many protocols for open abdominal cases suggest preoperative epidural, wound catheter, or transversus abdominis plane (TAP) block placement for postoperative pain management.1 This case study presents a middle-aged woman who underwent a pancreatoduodenectomy (PD) and received an alternate postoperative fascial plane block, a quadratus lumborum (QL) block, rather than the currently recommended TAP block, wound infiltration, or neuraxial anesthesia. Considering established ERAS protocols, the purpose of this case study is to examine the use of alternative forms of regional anesthesia for open abdominal cases, specifically the quadratus lumborum (QL) block, and compare it to the currently recommended TAP block.
Based on quality evidence regarding the benefits of the QL block, expanding ERAS protocols to regional anesthesia beyond wound infiltration and TAP blocks has the potential to produce increased pain management postoperatively, aiding in enhanced recovery and improved outcomes. Future, high-quality research should be initiated spanning a larger, more generalized population, including ASA III and IV, with BMIs not limited to 30 kg/m2, to confirm current study’s findings. Further evaluation of the local anesthetic’s diffusion via the TLF and the adjacent paravertebral space should be studied, due to the inquiries of the QL block’s definite mechanism of action that remain. Regarding the variation in fascial layers and dermatomes covered based on the type of QL block, further studies examining QL block injection sites should be considered.
Effect of different yeast-derived products on a red wine polyphenolic composition: influence of the wine age
Authors: Mekoue Nguela Julie , Sieczkowski Nathalie , Vernhet Aude 
Published: August 2024

The name “yeast-derived products” (YDPs) refers to different preparations obtained from yeast cells through various processes. These YDPs have different characteristics and applications in oenology, one being the improvement of the sensory properties of wines. This work aimed to identify the impact of YDPs obtained from different yeast strains and through different downstream inactivation processes on polyphenols in a red wine at different aging times. At an oenological dosage of 40 mg/L in a young wine, the addition of YDPs resulted in a variable decrease in total polyphenol index (TPI) (2 to 9 % depending on the YDPs) and a significant decrease in the precipitation of tannins (15 to 50 %) and high molecular weight (HMW) pigments (19 to 85 %) were obtained in the BSA assay, thus demonstrating the involvement of tannins and HMW pigments in interactions with the studied yeast-derived products. Pigment involvement led to a change in colour indices (L*a*b* and colour intensity), but in most cases this change was not visible to the human eye at the oenological dosage tested (40 mg/L). Experiments conducted on both the young wine and the same wine aged for three months using the same yeast-derived products, dosages and aging conditions revealed the influence of the chemical evolution of polyphenols on their interactions with YDPs. The significant variation observed in this study highlights the critical role of yeast selection and the yeast fragmentation downstream process on YDP efficiency. The high-pressure homogenisation (HPH) yeast fractions were shown to be more efficient than the corresponding whole yeast cells. Increasing the contact surface area between yeast cell constituents and wine matrix enabled by the HPH process may be a key strategy for enhancing the effectiveness of yeast derivatives in red wines, and in aged wines in particular, in which the phenolic compounds underwent changes and exhibited less interaction with the studied yeast-derived products. This research has contributed to increasing our understanding of and the potential for apply these processing aids in oenology.

Published: August 2024

Abstract

Cervical cancer (CC) represents a substantial public health burden, requiring the development of inventive therapeutic approaches. This study explored the functional relationship between the p63 isoform (ΔNp63) and miR-141-3p in modulating migration, invasion, and epithelial–mesenchymal transition (EMT) in two CC cell lines, CaSki, which are human cervical squamous carcinoma cells, and HeLa, which are human cervical adenocarcinoma cells. Our findings revealed dual functions of the ΔNp63-miR-141-3p-YAP1 axis, demonstrating its prometastatic role in HeLa cells through the upregulation of YAP1 and the promotion of proliferation, migration, invasion, and EMT. Conversely, the same axis demonstrated an antimetastatic function in CaSki cells by downregulating YAP1. Notably, YAP1 expression is significantly greater in ADC than in SCC, highlighting its contribution to the aggressive nature of ADC. These data indicate that targeting the ΔNp63-miR-141-3p-YAP1 axis can offer subtype-specific therapeutic options for managing CC.

Published: August 2024

Abstract

They appear to be structures that have a very important place in defining the civilizations that lived on historical buildings. In order to preserve historical buildings and pass them on to future generations, restoration and related strengthening practices are carried out as a result of structural performance analyzes and structural health monitoring studies. In this study, the Historical Karaz Bridge, which is in the form of an arch with a masonry stone wall bearing system and located within the borders of Erzurum Province, Turkey, was evaluated from a seismic perspective. As a result of the evaluations, it was aimed to investigate whether there was a need for reinforcement to protect the cultural structure and structural safety of the Historical Karaz Bridge. In line with the purposes of the research, the time history analysis method was preferred for the seismic evaluation of the Karaz Bridge. For analyzes in the time domain, data from 11 different earthquakes experienced around the world were used by scaling them specific to the structure. Time history analyzes performed according to today's accepted standards have shown that the bridge has limited displacement. In addition, it has been determined that there is limited stress distribution in the supporting support of the Bridge and at the same time, a sufficient damping mechanism has been formed against possible earthquakes. As a result of the study, it was concluded that there was no need for any strengthening process since the Historical Bridge exhibited performance at the usable limit level.

Published: August 2024

Abstract

In Minas Gerais state there are three biomes, the Cerrado, the Atlantic Forest and the Caatinga, which are home to significant biological diversity, including social wasps (Vespidae: Polistinae). These biomes have suffered significant losses of their original cover due to anthropogenic actions, making it important to understand insect distribution such as social wasps, which justifies carrying out inventory studies. Therefore, the aim of this study is to analyze the species richness and distribution of social wasps in Minas Gerais based on a literature review, as well as to add information for an unprotected and transitional area of Cerrado and Atlantic Forest in the municipality of Luminárias, southern Minas Gerais. Our results show that there are inventories in 32 locations in Minas Gerais, both inside and outside Conservation Units (CUs), with a higher concentration in the Atlantic Forest. In total, 118 social wasp species are recorded in the state, and most of them, 74, are considered rare, i.e. occurring in less than 20% of the localities. The Caatinga, along with the protected areas in the Cerrado and the Atlantic Forest in the eastern and northeastern parts of the state, is under-sampled. The municipality of Luminárias, despite not being located in a UC, has a considerable richness of rare species, two of which have only been previously recorded in Conservation Units. This allows us to infer that this municipality is home to a relevant vespid fauna for the state, corroborating other studies that suggest the creation of a UC for the region.

Published: August 2024

Abstract

The BiFe1 − xNdxO3 (x = 0.00, 0.03, 0.06, 0.09, 0.12) (BFNO) nanoparticles have been synthesized successfully through the solvothermal technique. The effect of neodymium (Nd) doping on structural, dielectric, magnetic, and magnetodielectric properties of BiFeO3 (BFO) multiferroic nanoparticles has been reported here. The rietveld refinement of X-ray diffraction (XRD) data confirms the formation of rhombohedral crystal structure (R3C space group) of the prepared nanomaterials. The average crystallite size obtained from XRD is in the range of 54 nm to 21 nm for pure and doped materials. The transmission electron microscope (TEM), high-resolution TEM (HRTEM), and energy dispersive X-ray (EDX) of the samples indicate the particle size, high crystallinity, and incorporation of Nd3+ ions respectively. The dielectric parameters and real-imaginary part of impedance behavior point out the transport mechanism of the doped samples. The magnetic and magnetodielectric properties of the doped nanomaterials have been enhanced than the pure BFO. The magnetic moment of BFNO samples increases due to the suppression of oxygen vacancies in accordance with the reduced super-exchange interaction of Fe2+-O-Fe3+. The leakage current and the multiferroic properties have been checked for all the samples at room temperature.

Published: August 2024

Abstract

Workpiece-fixture contact stiffness is an evaluation criterion for machining stability, and its effective prediction involves contact state analysis, surface profile analysis, and modeling of fixture and workpiece geometries, presenting a multi-source complexity. In this paper, a fractal theoretical model of contact stiffness under curved surface contact state is proposed, and the domain expansion factor and substrate deformation are considered to improve the prediction accuracy. First, based on the geometric theory and trigonometric function, the fractal theory model of microconvex body-curved surface contact is established. Then, the curved surface contact is equated to rough curved surface and smooth rigid curved surface, and analyzes the mechanical mechanism of the microconvex body-curved surface contact. Considering the influence of domain expansion factor and substrate deformation on total deformation, a fractal model of curved surface contact stiffness is obtained by force balance constraints. Then, a contact stiffness solution based on the adaptive Simpson's algorithm is proposed. Finally, the support-adsorption composite fixture is developed, and the model is verified through experiments. The results revealed that the average prediction error of the theoretical model is 11.24%. As the fractal dimension increases, the scale factor decreases, the contact stiffness gradually increases, and the fractal dimension is recommended to be limited to 1.7. Clamping force increases, intrinsic frequency and contact stiffness increase. In the case of a small initial support force, the phenomenon of increasing contact stiffness caused by the adsorption effect is more obvious, and the adsorption radius is not recommended to take a smaller value, such as 5-10mm. Support-absorption composite fixture increases contact stiffness while reducing clamping deformation.

Published: August 2024

Abstract

This work presents the results of theoretical and experimental studies on the use of silicon production waste in the form of microsilica as a raw material for the production of metallurgical grade silicon. It is known from practice that the granulometric composition of microsilica does not allow its use in metallurgical processing. The authors of this work propose its use together with a carbonaceous reducer as part of a briquetted monocharge. In this work, the optimal composition of the charge mixture for briquetting is determined. The main focus is on assessing the strength characteristics of the briquettes and analyzing their efficiency in the silicon smelting process. The strength of the briquettes was studied by compression and drop methods. As a result, in terms of strength and other characteristics, it is highly advisable to use briquettes consisting of microsilica and special coke at a ratio of 65/35%. The obtained batches of high-strength briquettes were tested for the smelting of metallurgical grade silicon in a large-scale laboratory ore-thermal furnace with the aim of replacing the traditional charge mixture (high-quality quartzites, petroleum coke, wood chips, etc.) with monobriquettes. It was established that the briquetted monocharge ensures more intensive reduction processes and improves melting conditions compared to the traditional charge. This leads to higher silicon recovery rates, which was confirmed by tests, during which the maximum recovery rate reached 82.76% with a 30% replacement of the charge with briquettes. Batch of metallurgical silicon with a Si content of 95–96% was obtained.
