Reconstructing the environmental impact of mining on mountain lakes.

Mountain lakes are particularly fragile ecosystems undergoing important ecological and depositional transformations associated with ongoing global change. However, the history of anthropogenic impacts on mountain lakes and their catchments is much longer, in many cases featuring millennia of summer pastoral farming. More recently, the growing demand for raw materials and energy linked to industrialization, particularly accelerated since the 19th century CE, meant a further increase in human impact on mountain areas.

An African perspective to biodiversity conservation in the twenty-first century.

Africa boasts high biodiversity while also being home to some of the largest and fastest-growing human populations. Although the current environmental footprint of Africa is low compared to other continents, the population of Africa is estimated at around 1.5 billion inhabitants, representing nearly 18% of the world's total population.

The microbiota-derived bile acid taurodeoxycholic acid improves hepatic cholesterol levels in mice with cancer cachexia.

Alterations in bile acid profile and pathways contribute to hepatic inflammation in cancer cachexia, a syndrome worsening the prognosis of cancer patients. As the gut microbiota impinges on host metabolism through bile acids, the current study aimed to explore the functional contribution of gut microbial dysbiosis to bile acid dysmetabolism and associated disorders in cancer cachexia. Using three mouse models of cancer cachexia (the C26, MC38 and HCT116 models), we evidenced a reduction in the hepatic levels of several secondary bile acids, mainly taurodeoxycholic (TDCA).

Clinical characteristics, management, and malignancy rate of oral lichen planus: a European multicenter study.

Introduction: Oral lichen planus (OLP) is a chronic inflammatory mucocutaneous condition that includes a spectrum of oral clinical manifestations ranging from mild painless white lesions to painful erosions and ulcers. The purpose of this European multicenter study is to describe the general characteristics of OLP lesions, the clinical and histopathological diagnosis, and the management of OLP at different European Oral Medicine and Maxillofacial Surgery centers, in order to minimize selections biases and provide information about the current trends in the treatment of OLP across Europe.

Materials And Methods: Data and histopathological records of patients with OLP were retrospectives revised and only those patients that fulfilled the diagnostic criteria from the 2016 position paper by American Academy of Oral and Maxillofacial Pathology were included.
