The article presents theoretical and experimental data on the results of the instrumental insemination and alimentation of queen bees. Queen bees were bred and inseminated. It has been established that when using various methods of keeping queen bees, a dynamic pattern is observed when there is safekeeping of queen bees. So, in 2019, before insemination in all experimental groups, the death of 1 to 4 infertile queens was observed. The highest indicator was recorded in the first experimental group; this is due to the fact that there were not enough young bees in the transfer cells to fully feed the infertile queen. In 2020, when using various methods of keeping queen bees before and after insemination, a similar pattern is observed with respect to the safety of queen bees. In a comparative aspect, before and after insemination, a high death rate of queens was recorded in the I-experimental group - 4 pcs, respectively fetal - 16 pcs. Whereas in the II-experimental and IV-experimental groups, the safest keeping of 18-19 queens was recorded respectively. Whereas in 2021, the greatest safety of fetal queen bees was in the IV-experimental group - 90%, and in the II-experimental and III-experimental groups, 85% each in comparison with the I-experimental group - 75%. Consequently, when using the method of keeping infertile queens in the transfer cells with accompanying bees, 5 pieces each, there is a high death rate of queen bees. It was also confirmed that the method of keeping queens in a nursery frame without accompanying bees is less effective compared to the method of keeping queens in a nursery frame without accompanying bees. Also, when obtaining fetal queens by instrumental insemination, attention should be focused on phenotypic indicators when selecting infertile queens, since the size of the queen bee is directly correlated with the number of egg tubes and, accordingly, affects the egg production of the fetal queen bee.

Understanding the causes of death in dogs enhances the diagnostic capabilities of veterinarians, as well as reduces animal mortality. Studies on this topic assist in the control and prophylaxis of epidemics and in structuring public health programmes. In total, 1 355 necropsy reports of dogs filed at the Veterinary Pathology Laboratory of the Federal University of Bahia, Northeast, Brazil (2005–2017) were analysed. The epidemiological information and anatomopathological diagnoses were obtained. The diagnosed diseases were classified into 10 categories. The frequency of the zoonoses, the overall age of the death (AD) of the dogs, and the AD of the dogs for each disease category were determined. Infectious and parasitic diseases were the most frequent primary causes of death in puppies (44.62%) and adult dogs (26.52%). In elderly dogs, most deaths occurred due to neoplasms (42.37%). Distemper (10.46%) was the most prevalent condition. A high frequency of zoonoses (6.12%) and a high death rate caused by diseases that could have been prevented (15.06%), such as distemper, parvovirus and canine visceral leishmaniasis, were reported. The AD in the population studied was eight years. The results confirmed the hypothesis of a high death rate in dogs in the state of Bahia, Northeast, Brazil, because of preventable infectious diseases.

Coronaviruses (CoV) are broad enveloped RNA viruses in humans and animals are mostly correlated with enteric and respiratory problems. Within the last decades, incidents of high death rate triggered by the spread of CoV from animals to humans have occurred. Certain pathogen city of CoV is known species-dependent as with the extent of infection; Complications typically appear in closely associated human hosts. Epidemiologists assume that the SARS virus arose in bats (natural reservoirs hosts) that were transferred to persons in Wuhan, China. Presently, the available diagnostic tests are aimed at the traditional early detection of the causes of pneumonia, promote disease prevention efforts and collaborate with research laboratories that can conduct pan coronavirus detection or controlled sequencing. No vaccine is sufficient to protect toward coronaviruses. Also there is no clear treatment for corona virus disease. Patients take comprehensive medication in clinics and typically heal on their own after several times. A vaccine can take up to 45 months to develop. Let’s stay safe during this period of time.

Stone Carvers

Elite residents of Charleston, South Carolina, sought a unique means of memorializing their dead: gravestones embellished with bust-length depictions of the deceased. Commissioned from stone carvers in Boston, these portrait gravestones reimagined the small, ivory form of the portrait miniature at a public scale suitable for the cemetery. This chapter examines why Charlestonians patronized this type of memorial, tying the gravestones to residents’ horror at the savagery unleashed upon corpses by putrefaction and to their desire to preserve bodies’ former politeness. Considering portrait gravestones along with mourning rituals and coffin construction illuminates the stones’ role as protective containers that kept savagery at bay, an important function given Charleston’s high death rate and steamy climate. Recognizing the memorials’ similarity to boundary markers, such as those erected to mark the Mason Dixon line, illuminates how the gravestones demarcated a space of colonial control. By erecting stone portraits of civil persons, Charlestonians created a social network with incredible permanence.

Computational tools are essential in the process of designing a CRISPR/Cas experiment for the targeted modification of an organism’s genome. Among other functionalities, these tools facilitate the design of a guide-RNA (gRNA) for a given nuclease that maximizes its binding to the intended genomic site, while avoiding binding to undesired sites with similar sequences in the genome of the organism of interest (off-targets). Due to the popularity of this methodology and the rapid pace at which it evolves and changes, new computational tools show up constantly. This rapid turnover, together with the intrinsic high death-rate of bioinformatics tools, mean that many of the published tools become unavailable at some point. Consequently, the traditional ways to inform the community about the landscape of available tools, i.e., reviews in the scientific literature, are not adequate for this fast-moving field. To overcome these limitations, we have developed “WeReview: CRISPR Tools,” a live, on-line, user-updatable repository of computational tools to assist researchers in designing CRISPR/Cas experiments. In its web site users can find an updated comprehensive list of tools and search for those fulfilling their specific needs, as well as proposing modifications to the data associated with the tools or the incorporation of new ones.

We present a comparison of clinical results between GDC treatment and direct surgery for ruptured cerebral aneurysms. From May 97 to April 98, 32 aneurysms were treated by direct surgery (DS) or GDC treatment. Treatments were selected depending on the clinical grade, degree of hematoma and anatomical aspect of the aneurysms. There were 13 GDC treated cases and 19 direct surgery cases. In GDC cases, there were acute stage embolization for ruptured basilar aneurysm, recurrence of case after clipping for BA-SCA aneurysm, advanced age cases, and systemic complication cases. Glasgow outcome scale (GOS) in GDC cases were 8 GR, 2 MD and 3 SD. GOS in direct surgery cases were 7 GR, 4 MD, 4 SD and 4 deaths. Cases of severe subarachnoid hemorrhage with hematoma influenced the high death rate in direct surgery group. There were three complications associated with the procedure in the GDC group, however, the rate improved after advancement of the procedure. In conclusion, GDC treatment for ruptured cerebral aneurysm was satisfactorily acceptable compared to the results of direct surgery, however, more cases will be needed for precise comparison.

Laemophloeus minutus (Ol.) has been reared on six food materials of a type with which the genus, Laemophloeus, is commonly associated in the field. Consideration of the length of egg to adult development, together with the mortality, recorded from each medium indicates that Manitoba wheat and whole-meal flour are equally favourable for the development of the species, followed in order of precedence by Plate maize, English wheat and, finally, National (85 per cent. extraction) and Canadian (70–75 per cent. extraction) flour which proved equally unfavourable.The stage of the life-history at which mortality mainly occurred varied with the diet. The high death-rate on English wheat was caused by the inability of newly hatched larvae to enter grains undamaged in the germ region. Mortality on National and Canadian flour occurred chiefly in the fourth instar.There were indications of cannibalism in both larval and adult stages, at any rate when the diet was unfavourable.The germ of wheat was attacked in preference to any other part of the grain. Maize germ was also consumed but whether it was preferred to the same extent as that of wheat was not established.Pupation was mainly, but not exclusively, intergranular in wheat. Normal cocoons were formed in National and Canadian flours but some larvae pupated in loose webbing or in flour free from webbing and freshly emerged adults were observed in unwebbed National and Canadian flour.
