First Time

For the first time, an analytical review of all, without exception, censorship stories of N.V. Gogol’s works is presented. An objective picture of Gogol's relationship with the censorship is being recreated. The findings of the study allow, with good reason, to judge about the interference of censors in the writer's works in a fundamentally different way, in comparison with the ideas offered by literary criticism of the previous period without solid evidence. Based on a thorough analysis, involving numerous archival sources, the common, stereotypical opinions about the extremely negative role of censorship in Gogol’s fate are being revised. The most significant negative result among all censorship interventions in Gogol's works was the activity of the censor of Westernizing views, opposed to the government, a professor at St. Petersburg University, A.V. Nikitenko. It is the numerous reductions of Nikitenko, И.А. Виноградов. Произведения Н .В. Гоголя и цензура 255 a friend of V.G. Belinsky, in Gogol's religious and patriotic book “Selected Passages from Correspondence with Friends” that the writer called “censorship murder”. No less significant was the intervention of the liberal censor in the texts of “Dead Souls”, “Theatrical Travel after the Presentation of a New Comedy” and other works of the writer. It is concluded that, with the exception of this “intrigue” against Gogol by the censor Nikitenko, on the whole Gogol's texts encountered relatively insignificant difficulties in censorship.

AbstractThe insect is a group of living thing that have the largest number of species. This article was compiled by aiming literature method studies at informing the negative and positive roles of insects in a farming and life. Some insects have a positive or negative role in agriculture and life. The negative role of insects in agriculture and life as cultivation plant, as a disease vector on the plant, and it cause humand being stickness. The positive role of insect is as pollinators, as a decomposer, as predators or parasitoids, as environment bioindikator, as the producer of the useful materials and beneficial in the field of health. Keywords: insects, vectors, natural enemies, pollinators, decomposer AbstrakSerangga merupakan kelompok makhluk hidup yang memiliki jumlah spesies terbanyak. Tulisan ini disusun dari studi literatur dan bertujuan menginformasikan peran negatif dan positif serangga dalam bidang pertanian dan kehidupan.  Beberapa anggota dari serangga memiliki peranan positif maupun negatif di bidang pertanian dan kehidupan.  Peran negatif serangga dibidang pertanian dan kehidupan adalah sebagai pemakan tumbuhan budidaya, sebagai vektor penyebab penyakit pada tanaman, dan sebagai penyebab penyakit pada manusia. Peran positif serangga adalah sebagai polinator atau penyerbuk, sebagai dekomposer atau pengurai, sebagai predator atau parasitoid (musuh alami), sebagai bioindikator lingkungan, sebagai penghasil bahan-bahan berguna dan bermanfaat  dalam bidang kesehatan. Kata Kunci: serangga, vektor, musuh alami, polinator, dekomposer

Negative Role

We have investigated the role of the Notch and Wingless signaling pathways in the maintenance of wing margin identity through the study of cut, a homeobox-containing transcription factor and a late-arising margin-specific marker. By late third instar, a tripartite domain of gene expression can be identified about the dorsoventral compartment boundary, which marks the presumptive wing margin. A central domain of cut- and wingless-expressing cells are flanked on the dorsal and ventral side by domains of cells expressing elevated levels of the Notch ligands Delta and Serrate. We show first that cut acts to maintain margin wingless expression, providing a potential explanation of the cut mutant phenotype. Next, we examined the regulation of cut expression. Our results indicate that Notch, but not Wingless signaling, is autonomously required for cut expression. Rather, Wingless is required indirectly for cut expression; our results suggest this requirement is due to the regulation by wingless of Delta and Serrate expression in cells flanking the cut and wingless expression domains. Finally, we show that Delta and Serrate play a dual role in the regulation of cut and wingless expression. Normal, high levels of Delta and Serrate can trigger cut and wingless expression in adjacent cells lacking Delta and Serrate. However, high levels of Delta and Serrate also act in a dominant negative fashion, since cells expressing such levels cannot themselves express cut or wingless. We propose that the boundary of Notch ligand along the normal margin plays a similar role as part of a dynamic feedback loop that maintains the tripartite pattern of margin gene expression.

Abstract: A comparative retrospective analysis of the results of a clinical - X-ray examination of 93 women doctors of ultrasound examinations of working age and 60 people was performed. control groups of age and experience comparable work with persons of major groups (nurses not associated with exposure to occupational ultrasound). Degenerative-dystrophic changes were revealed in the form of: osteorthrosis of the shoulder, elbow, wrist and interphalangeal joints, periarthrosis of the shoulder and elbow joints, small cyst-like clearances and enostoses in the bones of the wrists of the most loaded upper limb. The level of decrease in the mineral saturation and thickness of bone trabeculae in the areas of interest of the radius bones and distal phalanges of the hands was dependent on the severity of the clinical picture of vegetative-sensory polyneuropathy. Indicators of bone density and the state of bone trabeculae in the spongy structures of the distal radial bones and distal phalanges can be a kind of marker of the severity of OP. The use of modern methods for assessing the density and structure of bone tissue allows us to reduce the negative role of the so-called "human factor" and thus

Interleukin (IL)-33 is a chromatin-related nuclear interleukin that is a component of IL-1 family. IL-33 production augments the course of inflammation after cell damage or death. It is discharged into the extracellular space. IL-33 is regarded as an “alarmin” able to stimulate several effectors of the immune system, regulating numerous immune responses comprising cancer immune reactions. IL-33 has been demonstrated to influence tumorigenesis. However, as far as this cytokine is concerned, we are faced with what has sometimes been defined as the IL-33 paradox. Several studies have demonstrated a relevant role of IL-33 to numerous malignancies, where it may have pro- and—less frequently—antitumorigenic actions. In the field of hematological malignancies, the role of IL-33 seems even more complex. Although we can affirm the existence of a negative role of IL-33 in Chronic myelogenos leukemia (CML) and in lymphoproliferative diseases and a positive role in pathologies such as Acute myeloid leukemia (AML), the action of IL-33 seems to be multiple and sometimes contradictory within the same pathology. In the future, we will have to learn to govern the negative aspects of activating the IL-33/ST2 axis and exploit the positive ones.
