Full-text available
During the pre-vaccine era of the COVID-19 pandemic convalescent plasma has once again emerged as a major potential therapeutic form of passive immunization that in specific cases still represents irreplaceable treatment option. There is a growing concern that variable concentration of neutralizing antibodies, present in convalescent plasma which o...

COVID‐19 vaccines prevent severe forms of the disease, but do not warrant complete protection against breakthrough infections. This could be due to suboptimal mucosal immunity at the site of virus entry, given that all currently approved vaccines are administered via the intramuscular route. In this study we assessed humoral and cellular immune res...

During the ongoing COVID-19 epidemic many efforts have gone into the investigation of the SARS-CoV-2–specific antibodies as possible therapeutics. Currently, conclusions cannot be drawn due to the lack of standardization in antibody assessments. Here we describe an approach of establishing antibody characterisation in emergent times which would, if...

There is a large unmet need for a prophylactic vaccine against human cytomegalovirus (HCMV) to combat the ubiquitous infection that is ongoing with this pathogen. A vaccination against HCMV could protect immunocompromised patients and prevent birth defects caused by congenital HCMV infections. Moreover, cytomegalovirus (CMV) has a number of feature...

During COVID-19 pandemics, the availability of testing has often been a limiting factor during patient admissions into the hospital. To circumvent this problem, we adapted an existing diagnostic assay, Seegene Allplex SARS-CoV-2, into a point-of-care-style direct qPCR (POC dqPCR) assay and implemented it in the Emergency Department of Clinical Hosp...

DNA integrity is considered an important parameter of semen quality and is of significant value as a predictor of male fertility. Currently, there are several methods that can assess sperm DNA integrity. One such assay is the comet assay, or single-cell gel electrophoresis, which is a simple, sensitive, reliable, quick and low-cost technique that i...

Objectives: The patients with hematological malignancies are a vulnerable group to COVID-19, due to the immunodeficiency resulting from the underlying disease and oncological treatment that significantly impair cellular and humoral immunity. Here we report on a beneficial impact of a passive immunotherapy with convalescent plasma to treat a prolon...

Eukaryotic genome consists of long linear chromosomes. It is complex in its content and has dynamic features. It mostly consists of non-coding DNA of various repeats, often prone to recombination including creation of extrachromosomal DNA which can be re-integrated into distant parts of the genome, often in different chromosome. These events are us...

Cytochrome P450 enzymes (CYPs) are essential components of cellular detoxification system. We identified and characterized seven new cytochrome P450 gene transcript clusters in the populations of bivalve mollusc Mytilus galloprovincialis from three different locations. The phylogenetic analysis identified all transcripts as clusters within the CYP4...
Article
The marine water quality along the north-eastern part of Adriatic coast was assessed by measuring the lysosomal membrane stability in the digestive gland of marine mussel Mytilus galloprovincialis, as a marker of general stress. Mussels were sampled seasonally at five sites (mariculture Lim, Pula and Rijeka harbours, industrialized site Bakar and r...

The presence and activity of deoxyribonucleases in the cortex and endosome sections from a sponge, the sea orange Tethya aurantium, were investigated. The maximal enzyme activity in sponge homogenate was detected at pH 4.27, pH 7.0 and pH 8.5–8.75. Among different specimens, several distinct patterns of neutral DNase isozymes were observed in the c...

The hemocytes/coelomocytes DNA content in five selected marine invertebrates (sea mouse Aphrodita aculeata, spiny crab Maja crispata, sea star Echinaster sepositus, sea urchin Paracentrotus lividus, and tunicate Phallusia mammillata) was investigated by flow cytometry. The cell cycle analyses identified sea mouse coelomocytes as proliferating cells...

The cytokinesis-block micronucleus (CBMN) assay is one of the standard cytogenetic tools employed to assess chromosomal damage subsequent to exposure to genotoxic/cytotoxic agents, and is widely applicable to plant, animal and human cells. In the present study, the CBMN assay was used to assess the baseline damage in binuclear human peripheral bloo...
