Three paralogues in lampreys and gnathostomes-brothers or cousins?

is a key regulator of the early development of the vertebrate forebrain and sensory organs. In this study, we describe for the first time three paralogues in lamprey, representative of one of two basally diverged lineages of vertebrates-the agnathans. We also first describe three genes in sterlet-representative of one of the evolutionarily ancient clades of gnathostomes.

Hydroxychloroquine in obstetric antiphospholipid syndrome: rationale and results of an observational study of refractory cases.

Background: The current recommended therapy of obstetric antiphospholipid syndrome (APS) is a long-term anticoagulant therapy that affects the final event, namely, when the thrombosis has already occurred. Unfortunately, this schedule is not always effective and fails despite the correct risk stratification and an adequate adjusted dose.

Materials And Methods: From 2013 to 2020 we observed 217 women with antiphospholipid antibodies and obstetric morbidities who were treated with conventional treatment protocol (aspirin low doses ± LMWH).

Neonatal thrombosis.

Neonatal thromboembolism in pediatric patients is a rare but life-threatening condition mainly caused by combinations of at least 2 prothrombotic triggering risk factors such as the central venous lines, septic condition, and prematurity. Other risk factors include asphyxia, dehydration, liver dysfunction, inflammation, and maternal condition. Neonatal hemostatic system is different from one of the older children and adults.

Rabies surveillance in the Russian Federation.

Rabies is endemic to the Russian Federation. The disease incidence ranges between 2,000 and 4,000 cases annually. Between two and six cases in humans are also reported each year.

Detection of Antibodies Against Foot-and-Mouth Disease Virus Serotypes A, O and Asia-1 by ELISA in Strip-Dried Samples from Vaccinated Bovines.

Antibodies against foot-and-mouth disease virus serotypes A, O and Asia-1 were detected by ELISA in liquid and strip-dried samples from vaccinated bovines. The results showed high concordance of the results in both types of serum samples (coefficient of correlation varied from 0.89 to 0.
