Abstract:
Successful immunolabeling in electron microscopy of animal and plant tissues requires a combination of excellent antigen preservation while maintaining the original structure of the tissue. One important element is tissue embedding which accomplishes two goals for the immunohistochemist, the preservation of tissue specimen structure and maintenance of biological antigenicity. Tissue embedding in plastic resins is a common method in which several important elements must be considered.1.Fine tissue structure must not be damaged by the polymerization.2.The plastic must be stable to the electron b

Abstract:
A problem in immunocytochemistry is obtaining acceptable fixation of tissue while retaining antigenicity. Two concentrations (1% and 2.5%) of glutaraldehyde, with and without secondary fixation in 1% Osmium Tetroxide (OsO4) and varying fixation times were used. Fixation in 1% glutanddehyde for 3 h was adequate to preserve the tissue. Some loss of fine structure was visible under an electron microscope. A solution of 2.5% glutaraldehyde was more effective in preserving fine structure. At 2 h fixation the tissue was well preserved and only slight loss of tine detail was observed. A longer fixati

the article discusses the possibilities of improving the strength characteristics of fine-grained concrete. Modification of compositions and production technology of fine-grained high-strength concrete is possible with the use of natural and man-made raw materials of various chemical and mineral composition. It is shown that it is possible to increase the economic feasibility of high-strength fine-grained concretes with the preservation of performance characteristics due to the use of man-made raw materials and production waste.

Abstract:
Biomass ash from agricultural residues, which is typically discarded and causing waste and pollution, was evaluated in tea-bag form as a natural food preservative in this study, addressing research gaps on its effects and safety. In vitro tests on six biomass ash extracts demonstrated significant antibacterial activity. Specifically, the golden leaf fine branch camellia extract exhibited the highest efficacy against Staphylococcus aureus and Alternaria brassicicola, with an inhibition zone of 21 mm and an antibacterial efficiency of 70.2%. Fruit storage tests confirmed its preservative ability

We are working to improve methods for the study of cellular fine structure. Our approach is to advance each of the key steps in the preparation of specimens for EM: high quality fixation that will preserve both structure and antigenicity; methods for specific labeling; efficient acquisition of 3-D electron microscopic data; and software for 3-D reconstruction and display.Our work on high quality structure preservation has focused on methods for fast freezing and freeze substitution.

Somatic embryogenesis is one of the newest technology that applied for the mass production of cocoa. This research aims to evaluate the regeneration rate of somatic embryos through somatic embryogenesis propagation techniques on java fine flavor cocoa.

L’imagerie thoracique présente des défis importants, chaque modalité d’imagerie ayant ses propres limitations. Le scanner (CT), référence en imagerie pulmonaire, offre une haute résolution spatiale, mais utilise des rayonnements ionisants, posant des risques pour les patients nécessitant des examens fréquents. À l’inverse, l’IRM pulmonaire offre une alternative sans radiation, mais est limitée par des problèmes techniques tels qu’un faible contraste et des artefacts, limitant son adoption clinique à grande échelle.

Abstract Although platelets were one of the first types of cells to be studied using the electron microscope, a clear understanding of normal platelet architecture using electron microscopy had to await improved techniques for the isolation, preservation, and fixation of these cells. Similarly, an understanding of the changes in blood platelet fine structure during clotting required improvements in preparative techniques. The preservation and fixation of certain platelet subcellular structures, notably dense granules and contractile filaments, have presented particular challenges. In this chap

The article considers the processes leading to a change in the structure and properties as a result of calcination followed by acid treatment of heulandite-containing tuff from the Georgian Dzegvi-Tedzami deposit. The samples obtained by heat-acid treatment were studied by the X-ray energy dispersion spectra and diffraction patterns, as well as by adsorption of water and benzene methods. It was found that pre-heat treatment reduces weight loss and the degree of dealumination during subsequent acid treatment, and also affects the decationization process: with increasing preheating temperature,

Recently, the pretrain-finetuning paradigm has attracted tons of attention in graph learning community due to its power of alleviating the lack of labels problem in many real-world applications. Current studies use existing techniques, such as weight constraint, representation constraint, which are derived from images or text data, to transfer the invariant knowledge from the pre-train stage to fine-tuning stage. However, these methods failed to preserve invariances from graph structure and Graph Neural Network (GNN) style models. In this paper, we present a novel optimal transport-based fine-

Abstract:
Relation Extraction (RE) identifies relations between entities in text, typically relying on supervised models that demand abundant high-quality data. Various approaches, including Data Augmentation (DA), have been proposed as promising solutions for addressing low-resource challenges in RE. However, existing DA methods in RE often struggle to ensure consistency and contextual diversity in generated data due to the fine-grained nature of RE. Inspired by the extensive generative capabilities of large language models (LLMs), we introduce a novel framework named ConsistRE, aiming to maintain cont
