Twenty-one genital tracts from Eringer cows suffering from fertility problems were collected in the abattoir. The purpose of the study was the macroscopic evaluation…

In Italy (58 million inhabitants) over the last 15 years a decrease in caries incidence could be observed: Children (6-10 years old) 1970: 84.5%, DMF-T 4.77; 1980-85: 72%, DMF-T 3.64). Per capita sugar consumption went down from 32.0 kg in 1974 to 28.2 kg in 1983. 30.770 dentists are in practice--incl. medical doctors,…

BACKGROUND: Closing base wedge osteotomy (CBWO) is a common procedure to correct severe bunion deformities with high intermetatarsal angles. There are few data demonstrating the radiographic success of CBWOs. METHODS: We evaluated the radiographic outcomes of a CBWO. The primary aim was to assess the change in elevatu…

BACKGROUND: Recent advances in performance of natural language processing (NLP) techniques have spurred wider use and more sophisticated applications of NLP in radiology. This study systematically reviews the trends and applications of NLP in radiology within the last five years. METHODS: A search of three databases o…

PURPOSE OF REVIEW: The aim of this review is to provide an update of the therapeutic tools for thrombotic anti-phospholipid syndrome (APS), focusing on the last 5 years. RECENT FINDINGS: Early studies appointed anticoagulation at moderate intensity as the mainstay of treatment of thrombotic APS; in the last 5&#xa…

Ocean-atmosphere chemistry on Earth has undergone dramatic evolutionary changes throughout its long history, with potentially significant ramifications for the emergence and long-term stability of atmospheric biosignatures. Though a great deal of work has centered on refining our understanding of false positives for re…

BACKGROUND: Uganda has been reported as the most successful country in Africa in reducing the prevalence of HIV/AIDS from 18% to 6.4% over the last two decades. There is evidence to suggest that despite a significant decline between 1992 and 2002, HIV prevalence has stagnated over the last 5-9 years at between 6.1 and…

PURPOSE: To investigate the characteristics of nonunion and avascular necrosis following phalangeal neck fracture in children. METHODS: A cohort of all pediatric phalangeal neck fractures complicated by nonunion, with or without avascular necrosis of the phalangeal head, over the last 10 years was reviewed retrospecti…

Trematodes are the richest class of platyhelminths in the marine environment, infecting all classes of marine vertebrates as sexual adults and many phyla of marine invertebrates as part of their life cycles. Despite the cryptic nature of their existence (almost all marine trematodes are internal parasites), they have b…

The rate of enrichment of the Tula region flora with adventive species was quantitatively estimated taking into account the changes of their degree of naturalization during the last 200 years. Numerical score of degree of the naturalization for each species was used to compile the initial database: "0", species absent…

Two ombrotrophic peat bogs in Northwestern Spain provided a history of 4600 years of Pb accumulation. Highest Pb concentrations (84-87 microg g(-1)) were found near the bogs' surface, but there were also other significant peaks (6-14 microg g(-1)), indicating pre-industrial atmospheric pollution. The enrichment factors…

Doping of horses with recombinant human erythropoietin (rHuEPO) to illegally enhance their endurance capacity in horseracing has been reported during the last years. This leads to increased blood viscosity which can result in sudden death and is of concern for the horse welfare. Additionally, the horse can start produc…
