Abstract
New technologies in determining the gender of eggs will greatly help to end the extermination of male chickens, which will save a lot in the poultry industry. These technologies are so valuable and important that many companies and research centers are willing to make large investments to progress in this field. Today, two invasive and non-invasive methods are used to determine the gender of the egg. Invasive diagnostic methods often lead to a decrease in the viability of samples, while non-invasive methods with high accuracy and viability of samples have created a great development capability among researchers. In other words, invasive diagnostic methods determine the gender of the embryos inside the egg with a high percentage, but it can endanger the continuation of the hatching process and jeopardize food safety. However, the use of non-invasive methods in line with industrial use has priority due to the fact that there is no danger to the chick embryo in the process of sex determination. In this review study, while examining the importance of gender determination during hatching for the poultry industry, an attempt has been made to examine and compare all the new technologies used to determine gender in the egg-laying and hatching stages and compare its advantages and disadvantages.

Abstract
Since 2012, dengue disease has been considered as one of the most important viral diseases transmitted through arthropods and has become one of the major health problems in tropical and subtropical regions of the world In recent years. This virus has four serotypes and is transmitted through the Aedes mosquito. The aim of this Work is to investigate methods for diagnosing, treating, and controlling dengue disease. The method of conducting the study was based on observation and interpretation of information obtained from relevant scientific articles and books. This study was conducted in the spring and summer of 1403 by checking keywords such as Dengue virus, Aedes aegypti, dengue vaccine, detection, protection, chemical control on NCBI, Google, PubMed, WHO search engines. The molecular methods (real-time PCR) and immunoassay are often used to detect dengue virus. In order to prevent the disease, it is also recommended to control the life cycle of Aedes mosquito and use of quadrivalent live and attenuated Dengvxia and TAK-003 vaccines. The clinical treatment of this disease is done using serum therapy and the use of liquids. Finally, chemical and biological control methods of Aedes mosquito are also recommended as strategies to deal with this disease. In this review article, while describing the specific characteristics of dengue virus, the diagnostic and treatment methods of this disease have been scientifically investigated. It is also presented how to prevent control of this disease.
