Mathematical lipid correction of δ13C and effect of lipid extraction on δ15N of European eel (Anguilla anguilla) muscle: Lipid correction of δ13C in European eels.

Rationale: Carbon (δC) and nitrogen (δN) stable isotope analysis is a powerful tool to investigate diverse questions in fish ecology, such as their trophic position or migration strategies. These questions appear particularly important to protect endangered European eel. However, elevated lipid content in eel muscle can bias δC values, as lipids are C-depleted compared to proteins and carbohydrates.

Climbing Waterfalls: How Metabolism and Behavior Impact Locomotor Performance of Tropical Climbing Gobies on Reunion Island.

The life cycle of gobies of the Sicydiinae subfamily depends on climbing waterfalls. Two sympatric sicydiines species from Reunion Island, (SIL) and (COA), employ different climbing modes. SIL uses a steady "inching" mode interrupted by short rest periods, whereas COA exhibits short "power-burst" undulatory movements punctuated by longer rest periods.

Functional Diversity of Evolutionary Novelties: Insights from Waterfall-Climbing Kinematics and Performance of Juvenile Gobiid Fishes.

The evolution of novel functional traits can contribute substantially to the diversification of lineages. Older functional traits might show greater variation than more recently evolved novelties, due to the accrual of evolutionary changes through time. However, functional complexity and many-to-one mapping of structure to function could complicate such expectations.

Transcriptional effects of polyethylene microplastics ingestion in developing zebrafish (Danio rerio).

Over the last few decades, plastic waste has become an increasing environmental concern as it accumulates in every environment on our planet. Though traditionally seen as a macroscopic problem (i.e.

[First case of basidiobolomycosis with isolation of the strain diagnosed in the Central African Republic].

We report the first observation of subcutaneous phycomycosis with isolation of the strain in Central African Republic and the efficiency of fluconazole therapy.

[Tuberculosis and human immunodeficiency virus infection in the Central African Republic].

In order to determine the proportion of tuberculosis (TB) patients in Bangui (Central African Republic) infected with human immunodeficiency virus (HIV), we collected prospectively serum samples from all new TB patients seen at the University Hospital in Bangui during a three-month period (nov. 87-Jan. 88).

Metachromatic leukodystrophy. Ultrastructural and enzymatic study of a case of variant O form.

A variant of metachromatic leukodystrophy (MLD), Austin disease, is characterized by a multiple isozyme deficiency of arylsulfatase. A 3 1/2-year-old girl with progressive mental and physical deterioration had decreased activities of arylsulfatases A and B in the leukocytes, shown by acylamide gel electrophoresis. Under the electron microscope, biopsy specimens of the brain and the peripheral nerve showed lamellar structures with socalled zebra bodies in the cytoplasmic processes of glial cells, granulo-membranous inclusions with fingerprint configurations in neurons, and myelinlike material in Schwann cells.
