Viral Infections and Schizophrenia: A Comprehensive Review.

Schizophrenia is a complex mental disorder with multiple genetic and environmental factors contributing to its pathogenesis. Viral infections have been suggested to be one of the environmental factors associated with the development of this disorder. We comprehensively review all relevant published literature focusing on the relationship between schizophrenia and various viral infections, such as influenza virus, herpes virus 1 and 2 (HSV-1 and HSV-2), cytomegalovirus (CMV), Epstein-Barr virus (EBV), retrovirus, coronavirus, and Borna virus.

Antimicrobial Resistance, FlaA Sequencing, and Phylogenetic Analysis of Isolates from Broiler Chicken Flocks in Greece.

Human campylobacteriosis caused by thermophilic species is the most commonly reported foodborne zoonosis. Consumption of contaminated poultry meat is regarded as the main source of human infection. This study was undertaken to determine the antimicrobial susceptibility and the molecular epidemiology of 205 isolates derived from Greek flocks slaughtered in three different slaughterhouses over a 14-month period.

Ugo Cerletti (1877-1963): An Early Italian Father of Electroshock and a Pioneer in Many Other Ways.

This article provides a biographical review of the life and the professional achievements of the Italian doctor Ugo Cerletti and an introduction on electroshock. Throughout his medical career, he travelled and studied in many countries all over the world. Building upon his systematic and comprehensive analysis of mental diseases, Cerletti introduced electroshock, which, at his time, was a novel therapeutic method.

The purpose of this study was to present the evolution of ideas on the examination of urine from antiquity till our days. A thorough study of texts, medical books from antiquity till twentieth century along with a thorough review of the available literature in PubMed was conducted. The first observation on urine examination can be traced back to the Babylonian and Sumerian texts.

Mobile radiography units in Balkan Wars.

Introduction: It is known that the first radiological units were widely used during war conflicts, whereas the first application of military radiology took place during the Greco-Turkish War in 1897. However, until recently automobile radiology units were assumed to be used for the first time during World War I.

Method: Historical archives and reports were researched, and extensive research in available literature was also conducted.

Persistence of frequently transmitted drug-resistant HIV-1 variants can be explained by high viral replication capacity.

Background: In approximately 10% of newly diagnosed individuals in Europe, HIV-1 variants harboring transmitted drug resistance mutations (TDRM) are detected. For some TDRM it has been shown that they revert to wild type while other mutations persist in the absence of therapy. To understand the mechanisms explaining persistence we investigated the in vivo evolution of frequently transmitted HIV-1 variants and their impact on in vitro replicative capacity.

Patterns of drug resistance among newly diagnosed HIV-1 infected patients in Greece during the last decade: the crucial role of transmission networks.

Introduction: The prevalence of drug resistance is approximately 10% in Europe and North America among newly infected patients. We aim to investigate the temporal patterns of resistance among drug naive HIV-infected individuals in Greece and also to determine transmission networking among those with resistant strains.

Materials And Methods: Protease (PR) and partial reverse transcriptase (RT) sequences were determined from 2499 newly diagnosed HIV-1 patients, in Greece, during 2003-2013.

50 years after the death of George Nicholas Papanicolaou (1883-1962): evaluation of his scientific work.

The purpose of this review article is to summarise the scientific work of George Nicholas Papanicolaou, one of the most eminent figures in the 20th century history of clinical cytology and medicine. Fifty years after his death, his work still remains invaluable, from the early steps in biology and zoology to the application of the Pap test as the most important advancement in the prevention of cervical cancer. The publication of his Atlas was the first important step for the foundation of a new branch in medicine, that of exfoliative cytology.

Highights in the history of epilepsy: the last 200 years.

The purpose of this study was to present the evolution of views on epilepsy as a disease and symptom during the 19th and the 20th century. A thorough study of texts, medical books, and reports along with a review of the available literature in PubMed was undertaken. The 19th century is marked by the works of the French medical school and of John Hughlings Jackson who set the research on epilepsy on a solid scientific basis.

Plerixafor added to G-CSF-supported paclitaxel-ifosfamide-cisplatin salvage chemotherapy enhances mobilization of adequate numbers of hematopoietic stem cells for subsequent autografting in hard-to-mobilize patients with relapsed/refractory germ-cell tumors: a single-center experience.

An appreciable percentage of patients with relapsed/refractory germ-cell tumors (GCTs), candidates for high-dose chemotherapy (HDC) and autologous hematopoietic cell transplantation (HCT), fail to mobilize adequate hematopoietic stem cells (HSCs) numbers with granulocyte colony-stimulating factor (G-CSF)±salvage chemotherapy. Plerixafor has shown a potential to mobilize adequate CD34+HSCs numbers in this context. Here, we applied plerixafor in combination with G-CSF after salvage chemotherapy in 'poor' mobilizers with relapsed/refractory GCTs for HDC+HCT.

Multilocus sequence typing (and phylogenetic analysis) of Campylobacter jejuni and Campylobacter coli strains isolated from clinical cases in Greece.

Background: The molecular epidemiology of C. jejuni and C. coli clinical strains isolated from children with gastroenteritis, was investigated using the multilocus sequence typing method (MLST).

First report of a phylogenetic analysis of an autochthonous Plasmodium vivax strain isolated from a malaria case in East Attica, Greece.

Malaria has become an emerging infection in Greece, which is the doorstep to Europe for thousands of immigrants. With increasing immigration, cases with evidence of domestic transmission (autochthonous) are being reported. In the present study, an isolate of Plasmodium vivax from an autochthonous clinical case was subjected to phylogenetic analysis of the genes encoding the merozoite surface protein 1 (MSP-1) and the circumsporozoite protein (CSP).

Renal transplantation from hepatitis B surface antigen (HBsAg)-positive donors to HBsAg-negative recipients: a case of post-transplant fulminant hepatitis associated with an extensively mutated hepatitis B virus strain and review of the current literature.

Purpose: The purpose of this study was to present a fatal case of fulminant hepatitis B (FHB) that developed in a renal transplant recipient, immunized against hepatitis B, 1 year post transplantation.

Methods: Polymerase chain reaction amplification and full genome sequencing were performed to investigate whether specific mutations were associated with hepatitis B virus (HBV) transmission and FHB.

Results: Molecular analysis revealed multiple mutations in various open reading frames of HBV, the most important being the G145R escape mutation and a frameshift mutation-insertion (1838insA) within the pre-C/C reading frame.

Pioneers of exfoliative cytology in the 19th century: the predecessors of George Papanicolaou.

The purpose of our study was to summarize the knowledge on exfoliative cytology during the 19th century and to track down Papanicolaou's predecessors. A thorough study of texts, medical books and reports, together with a review of the available literature in PubMed, was undertaken. The study of cytological preparations as a diagnostic procedure can be traced back to the work of the famous French microscopist Alfred François Donné.

Integrating phylodynamics and epidemiology to estimate transmission diversity in viral epidemics.

The epidemiology of chronic viral infections, such as those caused by Hepatitis C Virus (HCV) and Human Immunodeficiency Virus (HIV), is affected by the risk group structure of the infected population. Risk groups are defined by each of their members having acquired infection through a specific behavior. However, risk group definitions say little about the transmission potential of each infected individual.

Milestones in the history of research on cardiac energy metabolism.

The present study summarizes the history of research on cardiac metabolism from antiquity till the 21st century. It describes important landmarks regarding the discovery of oxygen and of the 3 steps of cellular respiration, as well as major research on cardiac energy metabolism. For this purpose, we conducted a thorough search of original manuscripts, books, and contemporary reviews published in PubMed.

Dating the origin and dispersal of hepatitis B virus infection in humans and primates.

Unlabelled: The origin of hepatitis B virus (HBV) infection in humans and other primates remains largely unresolved. Understanding the origin of HBV is crucial because it provides a framework for studying the burden, and subsequently the evolution, of HBV pathogenicity with respect to changes in human population size and life expectancy. To investigate this controversy we examined the relationship between HBV phylogeny and genetic diversity of modern humans, investigated the timescale of global HBV dispersal, and tested the hypothesis of HBV-human co-divergence.

A brief chronicle of cytology: from Janssen to Papanicolaou and beyond.

The aim of our study was to outline and present the major hallmarks in the history of clinical cytology. For this purpose, an extensive research in modern literature and the PubMed database was undertaken. Furthermore, we studied original papers and books of the pioneers in cytopathology.
