The role of electron microscopy and associated techniques is assured in diagnostic pathology. At the present time, most of the progress has been made on tissues examined by transmission electron microscopy (TEM) and correlated with light microscopy (LM) and by cytochemistry using both plastic and paraffin-embedded materials. As mentioned elsewhere in this symposium, this has revolutionized many fields of pathology including diagnostic, anatomic and clinical pathology. It began with the kidney; however, it has now been extended to most other organ systems and to tumor diagnosis in general. The results of the past few years tend to indicate the future directions and needs of this expanding field. Now, in addition to routine EM, pathologists have access to the many newly developed methods and instruments mentioned below which should aid considerably not only in diagnostic pathology but in investigative pathology as well.

With the emergence of nanotechnology, new methods have been developed for engineering various nanoparticles for biomedical applications. Nanotheranostics is a burgeoning research field with tremendous prospects for the improvement of diagnosis and treatment of various cancers. However, the development of biocompatible and efficient drug/gene delivery theranostic systems still remains a challenge. Green synthetic approach of nanoparticles with low capital and operating expenses, reduced environmental pollution and better biocompatibility and stability is a latest and novel field, which is advantageous over chemical or physical nanoparticle synthesis methods. In this article, we summarize the recent research progresses related to green synthesized nanoparticles for cancer theranostic applications, and we also conclude with a look at the current challenges and insight into the future directions based on recent developments in these areas.

This article focuses on the experiences of gay men in the rural west and northwest region of Ireland, during a period of transformational social and political change in Irish society. These changes have helped facilitate new forms of LGBTQI visibility, and local radicalism in the region. Same-sex weddings, establishment of rural LGBT groups and marching under an LGBT banner at St Patricks Day parades would have been unthinkable in the recent past; but they are now becoming a reality. The men report continuing challenges in their lives as gay men in the nonmetropolitan space, but the emergence of new visibility, voice and cultural acceptance of LGBT people is helping change their lived experiences. The study demonstrates the impact of local activist LGBT citizens. Through their testimonies we can gain an insight into the many, varied and interwoven factors that have interplayed to create the conditions necessary for the men to: increasingly define themselves as gay to greater numbers of people in their localities; to embrace greater visibility and eschew strategies of silence; and aspire to a host of legal, political, cultural and social rights including same-sex marriage. Organic forms of visibility and local radicalism have emerged in the region and through an analysis of their testimonies we can see how the men continue to be transformed by an ever-changing landscape.

The cannabis plant (Cannabis sativa L.) produces an estimated 545 chemical compounds of different biogenetic classes. In addition to economic value, many of these phytochemicals have medicinal and physiological activity. The plant is most popularly known for its two most-prominent and most-studied secondary metabolites—Δ9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD). Both Δ9-THC and CBD have a wide therapeutic window across many ailments and form part of a class of secondary metabolites called cannabinoids—of which approximately over 104 exist. This review will focus on non-cannabinoid metabolites of Cannabis sativa that also have therapeutic potential, some of which share medicinal properties similar to those of cannabinoids. The most notable of these non-cannabinoid phytochemicals are flavonoids and terpenes. We will also discuss future directions in cannabis research and development of cannabis-based pharmaceuticals. Caflanone, a flavonoid molecule with selective activity against the human viruses including the coronavirus OC43 (HCov-OC43) that is responsible for COVID-19, and certain cancers, is one of the most promising non-cannabinoid molecules that is being advanced into clinical trials. As validated by thousands of years of the use of cannabis for medicinal purposes, vast anecdotal evidence abounds on the medicinal benefits of the plant. These benefits are attributed to the many phytochemicals in this plant, including non-cannabinoids. The most promising non-cannabinoids with potential to alleviate global disease burdens are discussed.

Abstract Background The nitrogen-containing polysaccharide chitin is the second most abundant biopolymer on earth and is found in the cell walls of diatoms, where it serves as a scaffold for biosilica deposition. Diatom chitin is an important source of carbon and nitrogen in the marine environment, but surprisingly little is known about basic chitinase metabolism in diatoms. Results Here, we identify and fully characterize 24 chitinase genes from the model centric diatom Thalassiosira pseudonana. We demonstrate that their expression is broadly upregulated under abiotic stresses, despite the fact that chitinase activity itself remains unchanged, and we discuss several explanations for this result. We also examine the potential transcriptional complexity of the intron-rich T. pseudonana chitinase genes and provide evidence for two separate tandem duplication events during their evolution. Conclusions Given the many applications of chitin and chitin derivatives in suture production, wound healing, drug delivery, and other processes, new insight into diatom chitin metabolism has both theoretical and practical value.

The article provides a survey of conducted educational programs „Office administration and records management", based on the content of module I. of the professional training in the Croatian State Archives (hereinafter referred to as HDA), which were held in the period from February 2016 to February 2019. The reason for choosing this exact period lies in the fact that since February 2016 a systematic distribution of anonymous polls to all the participants has begun and those polls have served as a basis for creating a compilation of statistical reports and analysis of data obtained from them. Anonymous polls were first experimentally distributed to participants in November 2015, and they were computer processed to serve as a model of experimentally conducted research based on the content of the module I of professional development in HDA. Survey research covers a period of 36 months, in which 10 courses in the period from February 2016 to February 2019 were held, with a total of 417 participants from all over Croatia. This article is conceptually structured according to the methodology which deals with survey research with a help of statistical methods, and the obtained results aim to improve the quality of teaching, to complete teaching materials and improve the insight into the final outcome of the course and the competencies that participants acquire at the end of the course.

Yod-coalescence involving alveolar consonants before Late Modern English /uː/ from earlier /iu > juː/ is still variable and diffusing in Present-day English. For example, the Oxford English Dictionary (OED) gives both (/tj dj/) and (/ʧ ʤ/) British English pronunciations for tune (/tjuːn/, /tʃuːn/), mature (/mǝˈtjʊǝ/, /mǝˈʧʊǝ/), duke (/djuːk/, /dʒuːk/) and endure (/ᵻnˈdjʊə/, /ɛnˈdjʊə/, /ᵻnˈdʒʊə/, /ɛnˈdʒʊə/, /ᵻnˈdjɔː/, /ɛnˈdjɔː/, /ᵻnˈdʒɔː/, /ɛnˈdʒɔː/). Extensive variability in yod-coalescence and yod-dropping is not recent in origin, and we can already detect relevant patterns in the eighteenth century from the evidence of a range of pronouncing dictionaries. Beal (1996, 1999) notes a tendency for northern English and Scottish authors to be more conservative with regard to yod-coalescence. She concludes that we require ‘a comprehensive survey of the many pronouncing dictionaries and other works on pronunciation’ (1996: 379) to gain more insight into the historical variation patterns underlying Present-day English.This article presents some results from such a ‘comprehensive survey’: the Eighteenth-Century English Phonology Database (ECEP). Transcriptions of all relevant words located are compared across a range of eighteenth-century sources in order to determine the chronology of yod-coalescence and yod-dropping as well as internal (e.g. stress, phoneme type, presence of a following /r/) and external (e.g. prescriptive, geographical, social) motivations for these developments.
