Reagent prediction with a molecular transformer improves reaction data quality.

Automated synthesis planning is key for efficient generative chemistry. Since reactions of given reactants may yield different products depending on conditions such as the chemical context imposed by specific reagents, computer-aided synthesis planning should benefit from recommendations of reaction conditions. Traditional synthesis planning software, however, typically proposes reactions without specifying such conditions, relying on human organic chemists who know the conditions to carry out suggested reactions.

Scientific support of small fruit growing in Russia and prospects for its development.

It is possible to achieve the target indices of the Russian Doctrine of Food Security (self-sufficiency in fruits and berries should be at least 60 %) by combining the competencies of science and business. At present, hundreds of varieties of small fruit crops are included in the State Register of Breeding Achievements Admitted for Use. Domestic breeders have obtained substantial results; the share of their assortment is 79-100 %.

New Poly(3-hydroxybutyrate) Microparticles with Paclitaxel Sustained Release for Intraperitoneal Administration.

Background: Poly(hydroxyalkanoates) (PHA) have recently attracted increasing attention due to their biodegradability and high biocompatibility, which makes them suitable for the development of new prolong drug formulations.

Objective: This study was conducted to develop new prolong paclitaxel (PTX) formulation based on poly(3- hydroxybutyrate) (PHB) microparticles.

Method: PHB microparticles loaded with antitumor cytostatic drug PTX were obtained by spray-drying method using Nano Spray Dryer B-90.

[Clinical and Laboratory Predictors for Forecasting the Outcomes of Ixodes Tick-Borne Borreliosis].

Objective: Our aim was to identify the most informative clinical and laboratory predictors of chronicity of Ixodes tick-borne borreliosis in the acute phase of the disease based on the "optimal cut-off values" (COV) and the predicted probability of the outcomes.

Methods: A retrospective cohort controlled study was carried out. We used the technique of ROC-analysis to estimate the information content of the clinical and laboratory indicators in patients with Ixodes tick-borne borreliosis in the acute phase of the disease with erythemal (n =16), non-erythemal (n = 77) forms of Ixodes tick-borne borreliosis and co-infection with the tick-borne encephalitis (n = 68) for the prediction of the outcomes: recovery or chronization.

Antitumor activity and toxicity of anti-HER2 immunoRNase scFv 4D5-dibarnase in mice bearing human breast cancer xenografts.

Ribonucleases (RNases) are a non-mutagenic alternative to harmful DNA-damaging anticancer drugs. Targeting of RNases with antibodies to surface antigens that are selectively expressed on tumor cells endows specificity to the cytotoxic actions of RNases. Barnase, a ribonuclease from Bacillus amyloliquefaciens, is a promising candidate for targeted delivery to cancer cells because of its insusceptibility to the ubiquitous cytoplasmic ribonuclease inhibitor, and its high stability and catalytic activity.
