Russian forest sequesters substantially more carbon than previously reported.

Since the collapse of the Soviet Union and transition to a new forest inventory system, Russia has reported almost no change in growing stock (+ 1.8%) and biomass (+ 0.6%).

Topical treatment of herpes simplex virus infection with enzymatically created siRNA swarm.

Background: Herpes simplex virus (HSV) is a common human pathogen. Despite current antivirals, it causes a significant medical burden. Drug resistant strains exist and they are especially prevalent in immunocompromised patients and in HSV eye infections.

Pathogenicity assessment of wild-type and mouse-adapted influenza A(H1N1) pdm09 viruses in comparison with highly pathogenic influenza A(H5N1) virus.

Here we compare the results of pathological and virological examinations of mice experimentally infected with either wild-type or mouse-adapted pandemic A(H1N1) pdm09 viruses and highly pathogenic avian influenza (HPAI) virus A(H5N1). Mice were sacrificed on days 1, 3, 6, and 10 post infection or whenever morbidity was severe enough to justify euthanasia. Morbidity rates were calculated on the basis of clinical signs (weight loss, poor hair coat, hunched posture and paresis); virus-induced disease was characterised by the histopathology of lung; virus dissemination was determined by virus isolation on organ samples of lung, brain, liver, kidney and spleen.

Inhibition of clinical pathogenic herpes simplex virus 1 strains with enzymatically created siRNA pools.

Herpes simplex virus (HSV) is a common human pathogen causing severe diseases such as encephalitis, keratitis, and neonatal herpes. There is no vaccine against HSV and the current antiviral chemotherapy fails to treat certain forms of the disease. Here, we evaluated the antiviral activity of enzymatically created small interfering (si)RNA pools against various pathogenic HSV strains as potential candidates for antiviral therapies.

[Serodiagnosis in the surveillance of the influenza virus circulation during the development of the pandemic caused by the A (H1N1)pdm09].

The goal of this work was to present the data of the study of the peculiarities of the generation factors of humoral immunity in the response to the infection with the pandemic influenza A (HIN1) pdmO9 in patients with different epidemiological anamnesis. High ability of the influenza viruses to spread over closed communities and the transfer of the maternal antibodies to babies, including a pandemic strain of the influenza virus A (H1N1) pdm09, was confirmed. The results of this study showed that the immune response to the surface antigens of the influenza virus (hemagglutinin and neuraminidase) was formed during the natural infection with the pandemic strains of the influenza A (H1N1) pdm09 in more than a half of the cases simultaneously.
