Bovine mastitis is very common in cows of both developed and developing countries. The prevalence of clinical and subclinical mastitis (SCM) varies from region to region. Hence, the present study was carried out to determine the prevalence of mastitis using three diagnostic tests by considering different risk factors like age, lactation, breed, season, quarters, and herd. The results showed tha...

BACKGROUND Lejeunea is a largely epiphytic, subcosmopolitan liverwort genus with a complex taxonomic history. Species circumscriptions and their relationships are subject to controversy; biogeographic history and diversification through time are largely unknown. METHODOLOGY AND RESULTS We employed sequences of two chloroplast regions (trnL-trnF, rbcL) and the nuclear ribosomal ITS region of 3...

In recent decades, democratic countries have signed hundreds of international environmental agreements (IEAs). Most of these are weak and do not include effective enforcement. To study this puzzle, we propose a positive theory of IEAs in which the political incumbents negotiate in the shadow of reelections. We show that incumbents are prone to negotiate treaties that are simultaneously overambi...

We report on the metagenome of a deep subsurface aquifer in the Tomsk region of Russia, sampled via an oil exploration borehole drilled to a depth of 2.8 km. Methanogenic archaea were present in the water along with members of various bacterial phyla, including Firmicutes, Chloroflexi, Bacteroidetes, Ignavibacteriae, and uncultured candidate divisions.

The Atlantic forest is a terrestrial biome that extends along the Brazilian coast and has been subject of intense deforestation for decades. There are presently several efforts to try to preserve the flora and fauna of what remains from this region (e.g., Coco et al. 2014, Maciel-Silva et al. 2014, Missagia et al. 2014), but several questions on how the distinct floristic units of this biome ar...

The human ANKRD2 gene was isolated from a cDNA library of human esophageal carcinoma cell line by immunoscreening (Moriyama et al., 2001), and independently cloned from two other laboratories in relation to skeletal muscle development and stretch-induced hypertrophy (Kemp et al., 2000; Pallavicini et al., 2001). It encodes an ankyrin-repeated protein highly homologous to the cardiac-restricted ...
