A technique is described for making semipermanent microscope slides of fungi using sticky tape. After being touched to a fungal colony, a modified segment of sticky tape is touched to ethyl alcohol and then immersed in a 50% glycerine solution containing cotton blue stain. Finally, it is transferred (sticky side up) to a microscope slide, covered with a cover glass, and sealed.

Embryonic aphids are a good source of aphid chromosomes when extruded and left for 15 minutes in 25% Ringer's solution, fixed for 1 hour in a mixture of 2 parts glacial acetic acid, 2 parts 95% ethyl alcohol, and 0.125 parts of chloroform. The embryos are then hydrolyzed for 5 minutes in normal hydrochloric acid at 60 °C. and stained in Gomori's hematoxylin for 30 minutes at 60 °C. After differentiation in 45% acetic acid for [Formula: see text]to 2 hours, the embryos are placed on a microscope slide, squashed under a cover glass, and mounted in 45% acetic acid. Individual plates are spread and flattened at low magnification with the point of a scalpel by tapping and pressing the cover glass over the figure. Unused embryos in 45% acetic acid and prepared slides will keep in "deep freeze" for about two weeks. Permanent preparations are made by floating the cover glasses from frozen slides in cold 95% ethyl alcohol, dehydrating in absolute alcohol, and mounting in an alcohol-based mounting medium.

1. Origin and Method of Experiments . I have frequently had to mount in water, for examination with the microscope, the powder of various rocks. Certain of the slides, when accidentally dried, exhibited rather interesting forms. These I showed to Professor Bonney, who encouraged me to try for farther results, so the experiments were continued with various powdered substances—many pigments (vermilion, indigo, sepia, &c.), chalk and other more or less friable rocks. At first, ordinary microscope slides were used, but afterwards, larger pieces of glass, in each case, generally with a cover-glass placed over the mud. The results seem to be worth describing, as affording familiar, almost homely illustrations which may throw some light on the origin of certain minor structures in rocks.

The Natural History Museum, London (NHM) has embarked on an ambitious programme to digitise its collections. One aim of the programme has been to improve the workflows and infrastructure needed to support high-throughput digitisation and create comprehensive digital inventories of large scientific collections. This paper presents the workflow developed to digitise the entire Phthiraptera (parasitic lice) microscope slide collection (70,663 slides). Here we describe a novel process of semi-automated mass digitisation using both temporary and permanent barcode labels applied before and during slide imaging. By using a series of barcodes encoding information associated with each slide (i.e. unique identifier, location in the collection and taxonomic name), we can run a series of automated processes, including file renaming, image processing and bulk import into the NHM’s collection management system. We provide data on the comparative efficiency of these processes, illustrating how simple activities, like automated file renaming, reduces image post-processing time, minimises human error and can be applied across multiple collection types.

Abstract This study aimed to isolation and identification of pathogenic fungi from Shatt – al-Arab River in Basra city, Fourteen water samples were collected from different area from Shatt-al-Arab River (AL Ashar, AL Tnoma, AL Makal, AL Qurna, AL Karma, AL Jabiluh, AL-Hartha), from October to December in 2017, with 250 ml volume, this samples centrifuged at 5000 rpm for 10 min at room temperature, the floating was removed and then take the precipitate and pour directly into the center of the media of SDA and PDA and then incubation in a temperature range25-27c for 4 days after that the growth on the media made pure culture and each fungi species diagnosed based on the cultural and microbiological phenotypes, smear prepared with lacto phenol cotton blue stain and the results show 57.1% of growth was Aspergillus niger, 85.7% Aspergillus flavus and 42.8% was Aspergillus candidus and 14.2% was Rhizopus, while the results show 42.8% of growth was Penicillium..

SummarySamples of butter were reworked at various times after removal from the churn, either in a laboratory mixer or by pressing between a microscope slide and cover glass. Moisture distribution was studied by microscopic examination and by indicator papers.Reworking within 30 min of completion of the original working caused no change in moisture distribution but delayed reworking caused aggregation of water droplets. The further the setting of the butter had proceeded before reworking, the greater was the extent of aggregation.Cream-cooling treatments which resulted in a softer butter delayed or decreased the aggregation of droplets caused by reworking.A theory is suggested relating changes on reworking with the formation of a crystal structure on setting.

Abstract Objective To describe the perspective of grossing technology and highlight the prospective of its development in histology laboratory. Methods Analysis of different components of grossing technology. Results Increased requirements for a specimen’s turnaround time and the advancements in modern processing equipment make the triage of workflow a significant part of a grossing person’s responsibilities. The implementation of digital pathology in morphology studies practice requires standardization of fixation, the thickness of gross section, and optimal embedding orientation. To meet tomorrow’s challenges, grossing technology should work on embedding automation and gross digital pathology to record gross sections corresponding the microscope slide. Specialization of grossing stations might be beneficial to the quality of processing and smooth workflow productivity. The emerging grossing technologist subspecialty requires development of a special training program. Conclusion Grossing technology can contribute to new challenges in modern histology laboratory, assuring high-quality microscope slides for the pathologist’s diagnosis and research evaluation.
