Abstract
Domestic cat (Felis catus) mothers may rely on offspring cries to allocate resources in use of individuals with greater chances for survival and sacrifice the weak ones in case of impossibility to raise the entire large litter. Potential victims of this maternal strategy can enhance their chances of survival, by producing vocalizations with traits mimicking those of higher-quality offspring. We compared acoustic traits of 4990 cries produced during blood sampling by 57 two-week-old captive feral kittens (28 males, 29 females); 47 of them survived to 90 days of age and 10 died by reasons not related to traumas or aggression. No relationship was found between acoustic parameters and kitten survival, however, positive relationship was found between survival and body weight. The cries had moderate cues to individuality and lacked cues to sex. Body weight correlated positively with fundamental frequency and negatively with call rate, duration, peak frequency and power quartiles. We discuss that dishonesty of acoustic traits of kitten quality could develop as adaptation for misleading a mother from allocation resources between the weaker and stronger individuals, thus enhancing individual chances for survival for the weaker littermates. Physical constraint, as body weight, may prevent extensive developing the deceptive vocal traits.

Abstract
The development of new approaches and drugs for effective control of the chronic and complicated forms of urogenital chlamydia caused by Chlamydia trachomatis, which is suspected to be one of the main causes of infertility in both women and men, is an urgent task. We used the technology of single-domain antibody (nanobody) generation both for the production of targeting anti-chlamydia molecules and for the subsequent acquisition of anti-idiotypic nanobodies (ai-Nbs) mimicking the structure of a given epitope of the pathogen (the epitope of the Chlamydial Type III Secretion System Needle Protein). In a mouse model, we have shown that the obtained ai-Nbs are able to induce a narrowly specific humoral immune response in the host, leading to the generation of intrinsic anti-Chlamydia antibodies, potentially therapeutic, specifically recognizing a given antigenic epitope of Chlamydia. The immune sera derived from mice immunized with ai-Nbs are able to suppress chlamydial infection in vitro. We hypothesize that the proposed method of the creation and use of ai-Nbs, which mimic and present to the host immune system exactly the desired region of the antigen, create a fundamentally new universal approach to generating molecular structures as a part of specific vaccine for the targeted induction of immune response, especially useful in cases where it is difficult to prepare an antigen preserving the desired epitope in its native conformation.

Abstract
The nasal cavity is an important site of allergen entry. Hence, it represents an organ where trans-epithelial allergen penetration and subsequent IgE-mediated allergic inflammation can potentially be inhibited. Intercellular adhesion molecule 1 (ICAM-1) is highly expressed on the surface of respiratory epithelial cells in allergic patients. It was identified as a promising target to immobilize antibody conjugates bispecific for ICAM-1 and allergens and thereby block allergen entry. We have previously characterized a nanobody specific for the major birch pollen allergen Bet v 1 and here we report the generation and characterization of ICAM-1-specific nanobodies. Nanobodies were obtained from a camel immunized with ICAM-1 and a high affinity binder was selected after phage display (Nb44). Nb44 was expressed as recombinant protein containing HA- and His-tags in Escherichia coli (E.coli) and purified via affinity chromatography. SDS-PAGE and Western blot revealed a single band at approximately 20 kDa. Nb44 bound to recombinant ICAM-1 in ELISA, and to ICAM-1 expressed on the human bronchial epithelial cell line 16HBE14o- as determined by flow cytometry. Experiments conducted at 4°C and at 37°C, to mimic physiological conditions, yielded similar percentages (97.2 ± 1.2% and 96.7 ± 1.5% out of total live cells). To confirm and visualize binding, we performed immunofluorescence microscopy. While Texas Red Dextran was rapidly internalized Nb44 remained localized on the cell surface. Additionally, we determined the strength of Nb44 and ICAM-1 interaction using surface plasmon resonance (SPR). Nb44 bound ICAM-1 with high affinity (10-10 M) and had slow off-rates (10-4 s-1). In conclusion, our results showed that the selected ICAM-1-specific nanobody bound ICAM-1 with high affinity and was not internalized. Thus, it could be further used to engineer heterodimers with allergen-specific nanobodies in order to develop topical treatments of pollen allergy.

Abstract
BACKGROUND Recent studies showed that a single injection of human monoclonal allergen-specific IgG antibodies significantly reduced allergic symptoms in birch pollen-allergic patients. Since the production of full monoclonal antibodies in sufficient amounts is laborious and expensive, we sought to investigate if smaller recombinant allergen-specific antibody fragments, that is, nanobodies, have similar protective potential. For this purpose, nanobodies specific for Bet v 1, the major birch pollen allergen, were generated to evaluate their efficacy to inhibit IgE-mediated responses. METHODS A cDNA-VHH library was constructed from a camel immunized with Bet v 1 and screened for Bet v 1 binders encoding sequences by phage display. Selected nanobodies were expressed, purified, and analyzed in regards of epitope-specificity and affinity to Bet v 1. Furthermore, cross-reactivity to Bet v 1-homologues from alder, hazel and apple, and their usefulness to inhibit IgE binding and allergen-induced basophil activation were investigated. RESULTS We isolated three nanobodies that recognize Bet v 1 with high affinity and cross-react with Aln g 1 (alder) and Cor a 1 (hazel). Their epitopes were mapped to the alpha-helix at the C-terminus of Bet v 1. All nanobodies inhibited allergic patients' polyclonal IgE binding to Bet v 1, Aln g 1, and Cor a 1 and partially suppressed Bet v 1-induced basophil activation. CONCLUSION We identified high-affinity Bet v 1-specific nanobodies that recognize an important IgE epitope and reduce allergen-induced basophil activation revealing the first proof that allergen-specific nanobodies are useful tools for future treatment of pollen allergy.

Abstract
Secondary contact zones between related species are key to understanding speciation mechanisms. The Central European sympatry zone of West European (Erinaceus europaeus) and northern white-breasted (Erinaceus roumanicus) hedgehogs is well studied, whereas data on the Eastern European sympatry zone are scarce. We examined the genetic variation in Russian populations using the mitochondrial Cytb gene, TTR intron 1 and 11 microsatellites to assess genetic variability and distribution patterns. In contrast to the Central European sympatry zone, we found evidence of ongoing hybridization between the two species in the sympatry zone of European Russia, where the proportion of individuals with mixed ancestry was c. 20%. Our data indicate bi-directional mtDNA introgression, but with a higher frequency of E. europaeus haplotypes in hybrids. The proportion of pure specimens with introgressed mitotypes is higher in E. roumanicus than in E. europaeus. Nuclear data showed the prevalence of the genetic contribution from E. roumanicus in admixed individuals. Demographic analyses indicated recent population growth in E. europaeus and little change in E. roumanicus, suggesting that E. europaeus colonized East Europe later than E. roumanicus.

Abstract
The dynamics of body temperature was used to determine the food intake synchronization in starlings located at a distance of 105 km from each other. Thermal accumulators were implanted intraperitoneally to the birds; the birds had free access to food or were kept under the conditions of food deprivation. It was found that food intake moments significantly more often coincided with an accuracy of up to a minute even in the birds separated by a considerable distance. The difference in time of sunrise of a few minutes, as well as the conditions of constant lighting did not affect the synchronism of food intake. On the basis of the data obtained, it can be assumed that there is a certain external factor, probably of an electromagnetic nature, which synchronizes the functional activity of the body, including food intake.

Abstract
The aim of the study was to identify ultradian (intraday) and infradian (multi-day) rhythms in the dynamics of testosterone concentration in the blood serum of white-breasted hedgehogs. Blood sampling was performed from the femoral veins of 12 male hedgehogs. We found ultradian rhythms of testosterone on both sampling dates-March 7-8 (a day length of 11 hours and 15 minutes) and May 10-11 (a day length of 16 hours). An 8-hour rhythm of testosterone concentration has been established. The acrophases were at the same times in both photoperiods and thus independent of sunset times. The study of the infradian rhythms of testosterone was daily carried out on May 22-June 3, at 07:40 to 08:50 and from June 27 to July 7, at 16:15-16:50. It revealed an infradian rhythm of the testosterone concentration with a period of 4-days in both the morning and the evening sampling. According to our previous investigation, the infradian rhythms of testosterone among individual hedgehogs, rodents and primates have the same period. That indicates the common mechanisms for their formation. In case of experimental studies, the phase of ultradian and infradian biorhythms will need to be taken into account because the testosterone concentration in acrophase is 2-4 times higher than in bathyphase.

Abstract
The rhythms of short-term arousal episodes, associated with normalization of low body temperature, were studied in hibernating Erinaceus roumanicus. The episodes of body temperature recovery during hibernation were 1.7 times more incident during the acrophase of 4.058-day rhythm of glucocorticoid hormones, detected previously, than during the batiphase of this rhythm. Ultradian rhythm of arousal episodes conformed to a 4-h biorhythm: the maximum number of body temperature resumption episodes was recorded at 00.00-01.00, 04.00-05.00, 08.00-09.00, 12.00-13.00, 16.00-17.00, and 20.00-21.00. These data indicated that in mammals the mechanisms of infradian and ultradian rhythm maintenance were stable and did not depend on body temperature or were determined by external factors with periods of 4.058 days and 4 h.

Abstract
A new efficient method for the parallel and sequential stepwise generation of single-domain antibodies to various high-abundance human-plasma proteins has been described. Single-domain antibodies have a number of features that favorably distinguish them from classical antibodies. In particular, they are able to recognize unusual unique conformational epitopes of native target proteins, small in size, and relatively easily produced and modified; have enhanced stability; and rapidly renature after denaturation. As a consequence, the immunosorbents that utilize these antibodies can be reused without any significant loss of activity. The principal novelty and universality of the described method is that it enables the sequential generation of antibodies to a number of high-abundance and yet unknown antigens of a complex protein mixture without the need for purified antigens. The effectiveness of the method is demonstrated by the example of generation of single-domain antibodies to a number of high-abundance proteins of the human blood plasma. The produced antibodies are promising biotechnological tools that can be used to develop prototypes for new diagnostic and therapeutic agents, as well as appropriate immunoaffinity-based methods for removal, enrichment, analysis, and/or targeting of specified proteins and their complexes from (in) the human blood. As we show, the generated single-domain antibodies can be efficiently used in designing new immunosorbents. As a rule, commercially available analogous immunosorbents that utilize classical antibodies remove many major proteins from the blood plasma immediately, while immunosorbents for many individual proteins are difficult to find and rather expensive. Single-domain antibodies generated by our method are unique new materials that allow for the development of more efficient and delicate approaches to pretreatment of plasma and the analysis of various blood plasma biomarkers.

Abstract
One effective method for the prevention and treatment of influenza infection is passive immunization. In our study, we examined the feasibility of creating an antibody-based preparation with a prolonged protective effect against influenza virus. Single-domain antibodies (sdAbs) specific for influenza virus hemagglutinin were generated. Experiments in mouse models showed 100% survivability for both intranasal sdAbs administration 24h prior to influenza challenge and 24h after infection. sdAb-gene delivery by an adenoviral vector led to gene expression for up to 14days. Protection by a recombinant adenovirus containing the sdAb gene was observed in cases of administration prior to influenza infection (14d-24h). We also demonstrated that the single administration of a combined preparation containing sdAb DNA and protein expanded the protection time window from 14d prior to 48h after influenza infection. This approach and the application of a broad-spectrum sdAbs will allow the development of efficient drugs for the prevention and treatment of viral infections produced by pandemic virus variants and other infections.

Abstract
This work continues a series of recently published studies that employ recombinant single-domain antibody (sdAb, or nanobody®) generation technologies to battle viruses by a passive immunization approach. As a proof of principle, we describe a modified technique to efficiently generate protective molecules against a particular strain of influenza virus within a reasonably short period of time. This approach starts with the immunization of a camel (Camelus bactrianus) with the specified antigen-enriched material presented in as natural a form as possible. An avian influenza virus A/Mallard/Pennsylvania/10218/84 (H5N2) adapted for mice was used as a model source of antigens for both the immunization and phage display-based selection procedures. To significantly increase activities of initially selected monovalent single-domain antibodies, we propose a new type of sdAb formatting that involves the addition of a special type of coiled-coil sequence, the isoleucine zipper domain (ILZ). Presumably, the ILZ-containing peptides adopt trimeric parallel conformations. After the formatting, the biological activities (virus neutralization) of the initially selected anti-influenza virus (H5N2) sdAbs were significantly increased. Intraperitoneal or intranasal administration of the formatted sdAb at 2h before or 24h after viral challenge specifically protects mice from lethal infection with influenza virus. We hope that the described approach combined with the selection focused on particular conservative epitopes will lead to the generation of sdAb-based molecules protective against a broad spectrum of influenza virus subtypes.
