Tusavirus 1 of species (family ) was first identified in humans and later in small ruminants (caprine and ovine). This study reports the full-length coding sequences (~4400-4600 nt) of three novel tusavirus-related protoparvoviruses from ovine ("misavirus", PV540792), for the first time bovine ("sisavirus", PV540793) and subsequently from caprine ("gisavirus" PV540850/51) fecal samples, using next-generation sequencing (NGS) and PCR techniques. Their NS1, VP1 and VP2 proteins shared 61-63% amino acid identities with each other and with tusaviruses, suggesting these three viruses belong to three novel species in the genus .

Mushroom-forming fungi (Agaricomycetes) are emerging as pivotal players in several fields of science and industry. Genomic data for Agaricomycetes are accumulating rapidly; however, this is not paralleled by improvements of gene annotations, which leave gene function notoriously poorly understood. We set out to improve our functional understanding of the model mushroom Coprinopsis cinerea by integrating a new, chromosome-level assembly, high-quality gene predictions, and functional information derived from broad gene-expression profiling data.

The black-headed gull is the most common nesting gull species in Hungary. Based on the lifestyle and feeding habits of the black-headed gull, which is highly adapted to the human environment, they can be carriers and spreaders of potential human and other animal pathogens. Between 2014 and 2018 within the framework of the "Life Bird Ringing program" a total of 7 faecal samples were collected from gulls and one sample (MR04) was randomly selected for viral metagenomics and mass sequencing.

Traditional advanced therapies in Parkinson's disease (PD) with motor fluctuations and dyskinesias like continuous apomorphine infusion (CSAI), levodopa-carbidopa intestinal gel (LCIG), levodopa-carbidopa entacapone intestinal gel (LECIG), or deep brain stimulation (DBS) have played a central role in managing therapy-related complications. Recently, continuous subcutaneous foslevodopa/foscarbidopa infusion (CSFLI) has emerged as a novel therapeutic option. This manuscript provides insights from one year of real-world experience with CSFLI, addressing critical questions that clinicians face when selecting the most appropriate therapy for advanced PD.

Introduction: CD20+ T-cells were described firstly in peripheral blood and later in bone marrow in patients with hematological tumors, and certain immune-mediated diseases. During our hematological diagnostic work, this peculiar subgroup of lymphocytes has been consistently observed associated with untreated monoclonal gammopathy of undetermined significance (MGUS) and myeloma (MM). Despite the expanding literature data, the exact function of CD20+ T cells remains unclear.

Article Synopsis
  • The study aimed to investigate how low temperatures experienced by rice leaves influence stress responses in the roots and how light conditions affect these processes.
  • Researchers exposed rice plants to low temperatures (12°C) while keeping roots at normal temperatures (27°C) and analyzed gene expression changes in the roots.
  • Findings revealed that low temperature exposure led to more down-regulated genes, particularly affecting nitrogen metabolism and related signaling, with additional insights from real-time PCR and metabolomics showing that both leaf cold exposure and light conditions impact root stress responses.

  • Current estimates of genetic variants linked to Parkinson's disease (PD) show limitations and biases across different populations, complicating patient recruitment for clinical trials focused on genetic therapies.
  • The Rostock Parkinson's disease (ROPAD) study analyzes data from 12,580 PD patients across 16 countries, revealing that 14.8% had a genetic test positive for PD-related variants, particularly in specific genes like GBA1 and LRRK2.
  • Findings indicate higher positivity rates in patients with earlier onset (age ≤ 50) or a positive family history, emphasizing the need for more extensive genetic investigation to improve patient stratification for future clinical trials.

Parkinson's Disease (PD) is a multifaceted and progressive disorder characterized by a diverse range of motor and non-motor symptoms. The complexity of PD necessitates a multidisciplinary approach to manage both motor symptoms, such as bradykinesia, gait disturbances and falls, and non-motor symptoms, including cognitive dysfunction, sleep disturbances, and mood disorders, which significantly affect patients' quality of life. Pharmacotherapy, particularly dopaminergic replacement therapy, has advanced to alleviate many symptoms.

Evidence has been accumulating that elements of the vertebrate pituitary adenylate cyclase-activating polypeptide (PACAP) system are missing in non-chordate genomes, which is at odds with the partial sequence-, immunohistochemical-, and physiological data in the literature. Multilevel experiments were performed on the great pond snail (Lymnaea stagnalis) to explore the role of PACAP in invertebrates. Screening of neuronal transcriptome and genome data did not reveal homologs to the elements of vertebrate PACAP system.

Neurofibromatosis type 1 (NF1) is a clinically heterogeneous neurocutaneous disorder inherited in autosomal dominant manner. Approximately 5-10% of the cases are caused by microdeletions involving the gene and its flanking regions. Microdeletions, which lead to more severe clinical manifestations, can be subclassified into four different types (type 1, 2, 3 and atypical) according to their size, the genomic location of the breakpoints and the number of genes included within the deletion.
