Characteristics of children and adolescents with multidrug-resistant and rifampicin-resistant tuberculosis and their association with treatment outcomes: a systematic review and individual participant data meta-analysis.

Background: There are few data on the treatment of children and adolescents with multidrug-resistant (MDR) or rifampicin-resistant (RR) tuberculosis, especially with more recently available drugs and regimens. We aimed to describe the clinical and treatment characteristics and their associations with treatment outcomes in this susceptible population.

Methods: We conducted a systematic review and individual participant data meta-analysis.

Diagnosis of tuberculosis infection in children with a novel skin test and the traditional tuberculin skin test: An observational study.

Background: A novel skin test-called Diaskintest (DT)-containing specific M. tuberculosis antigens is in clinical use in the Russian Federation (RF). This test may improve diagnosis of tuberculosis (TB) infection.

Photoinduced changes in subcellular structures of the retinal pigment epithelium from the Japanese quail Coturnix japonica.

Fifteen-week-old sexually mature female Japanese quails (Coturnix japonica) grown under various lighting conditions were used in the study. It was found that the number of mitochondria and phagosomes was increased by 1.5-fold in the retinal pigment epithelium from birds reared for 95 days under blue light (440-470 nm) vs.

[Embryogenesis of the Japanese quail in hypomagnetic conditions applied to deep space flights].

During future interplanetary flights and on the lunar base, astronauts and bioregenerative systems on the space ship will occur in an interplanetary magnetic field, which is much lower than the habitual geomagnetic field (GMF). It is known that hypomagnetic conditions have an adverse biological effect on human beings and other living systems. In our research the Japanese quail has been chosen as one of the possible elements of the bioregenerative live support system.
