Rodents are popular companion animals and are often kept as pets for children. However, they can be reservoirs of a variety of zoonotic pathogens. As little attention is being paid to the possibility of acquiring parasitic infections from pet rodents, the occurrence of Hymenolepis nana in rodents from pet shops and breeding clubs of Slovakia was surveyed, with parallel genetic analyses to type isolates from rodent species.

The mouse bile duct tapeworm Hymenolepis microstoma, is a potentially zoonotic species with a wide variety of reported definitive hosts of rodent genera. In the present study the occurrence of H. microstoma in free-living small mammals in selected areas of Slovakia and the retrospective analysis of epidemiological data published in Slovakia were performed. Hymenolepis microstoma was detected in two animal species, the common shrew (Sorex araneus) and the European hamster (Cricetus cricetus) of 186 small mammals examined from two ecosystems, urban and natural ecosystem of national park.

Introduction: Concerns were raised about a high occurrence of hepatocellular carcinoma (HCC) after successful treatment of chronic hepatitis C (CHC) by direct-acting antivirals (DAAs). Areas covered: The authors summarize the clinical studies reporting the occurrence rate and risk factors of HCC after DAAs in CHC. Expert opinion: The recent introduction of all-oral DAAs has substantially changed the scenario of CHC, achieving a sustained virological response (SVR) in >90% of cases.

In this review article, the occurrence of harpagide in the plant kingdom and its associated biological activities are presented and detailed for the first time. The presence of harpagide has been reported in several botanical families within Asteridae, and harpagide has been observed to exert a wide number of biological activities such as cytotoxic, anti-inflammatory, and neuroprotective. These results show how harpagide can be recovered from several natural sources for several pharmacological purposes even if there is a lot to still be studied.

In this review article, the occurrence of nor-lignans and their biological activities are explored and described. Nor-lignans have proven to be present in several different families also belonging to chemosystematically distant orders as well as to have many different beneficial pharmacological activities. This review article represents the first one on this argument and is thought to give a first overview on these compounds with the hope that their study may continue and increase, after this.
