ArcticBirdSounds: An open-access, multiyear, and detailed annotated dataset of bird songs and calls.

Tracking biodiversity shifts is central to understanding past, present, and future global changes. Recent advances in bioacoustics and the low cost of high-quality automatic recorders are revolutionizing studies in biogeography and community and behavioral ecology with a robust assessment of phenology, species occurrence, and individual activity. This large volume of acoustic recordings has recently generated a plethora of datasets that can now be handled automatically, mostly via big data methods such as deep learning.

The Legionella Kinase LegK2 Targets the ARP2/3 Complex To Inhibit Actin Nucleation on Phagosomes and Allow Bacterial Evasion of the Late Endocytic Pathway.

Unlabelled: Legionella pneumophila, the etiological agent of legionellosis, replicates within phagocytic cells. Crucial to biogenesis of the replicative vacuole is the Dot/Icm type 4 secretion system, which translocates a large number of effectors into the host cell cytosol. Among them is LegK2, a protein kinase that plays a key role in Legionella infection.

Protein kinase LegK2 is a type IV secretion system effector involved in endoplasmic reticulum recruitment and intracellular replication of Legionella pneumophila.

Legionella pneumophila is the etiological agent of Legionnaires' disease. Crucial to the pathogenesis of this intracellular pathogen is its ability to subvert host cell defenses, permitting intracellular replication in specialized vacuoles within host cells. The Dot/Icm type IV secretion system (T4SS), which translocates a large number of bacterial effectors into host cell, is absolutely required for rerouting the Legionella phagosome.

[Neuropathology and pregnancy. 189 consecutive cases (1971--1976) (author's transl)].

The authors report 189 case histories of pregnant women who had a neurological disorder, which either existed before the pregnancy or were discovered during the pregnancy. The most frequent aetiological conditions were, epilepsy, psychoses, vascular accidents, tumours and disseminated sclerosis. Pregnancy and neuropathology are an association for which the prognosis as a whole is good and linked to the time in the pregnancy when the neurological condition, whether it is stable or not, is discovered.

[Clear cell vaginal adenocarcinoma in young girls. Apropos of a personal case].

A personal case which has been studied has given the authors the opportunity of analysing the characteristics of clear-cell adenocarcinoma of the vagina in a young girl. Adhesions are most often discovered in cases of metrorrhagia or discharge about the time of puberty. Thence as a friable tumour on the anterior wall of the vagina.

[Prolactin adenoma. Hypophysectomy during pregnancy].

The authors report a case of amenorrhoea with galatorrheoa due to a prolactin adenoma secondary to an inducer of ovulation (HMG and HCG) and in which pregnancy occurred. There was sudden progression of the adenoma with formation of a haematoma and the necessity for emergency surgery. In the light of this case, the risks and indications of inducers of ovulation in the sterile woman complaining of amenorrhoea with galactorrhoea are discussed.
