Microfluidic-based virus detection methods for respiratory diseases

With the recent SARS-CoV-2 outbreak, the importance of rapid and direct detection of respiratory disease viruses has been well recognized. The detection of these viruses with novel technologies is vital in timely prevention and treatment strategies for epidemics and pandemics. Respiratory viruses can be detected from saliva, swab samples, nasal fluid, and blood, and collected samples can be analyzed by various techniques. Conventional methods for virus detection are based on techniques relying on cell culture, antigen-antibody interactions, and nucleic acids. However, these methods require trained personnel as well as expensive equipment. Microfluidic technologies, on the other hand, are one of the most accurate and specific methods to directly detect respiratory tract viruses. During viral infections, the production of detectable amounts of relevant antibodies takes a few days to weeks, hampering the aim of prevention. Alternatively, nucleic acid–based methods can directly detect the virus-specific RNA or DNA region, even before the immune response. There are numerous methods to detect respiratory viruses, but direct detection techniques have higher specificity and sensitivity than other techniques. This review aims to summarize the methods and technologies developed for microfluidic-based direct detection of viruses that cause respiratory infection using different detection techniques. Microfluidics enables the use of minimal sample volumes and thereby leading to a time, cost, and labor effective operation. Microfluidic-based detection technologies provide affordable, portable, rapid, and sensitive analysis of intact virus or virus genetic material, which is very important in pandemic and epidemic events to control outbreaks with an effective diagnosis.Qatar National Research Fun

Use of Alcoholic Beverages and Other Psychoactive Substances Among Women in Turkey: Medical, Biological, and Social Consequences. A Pilot Study

This research was planned for determining the genitourinary health problems of alcohol and other psychoactive substance-dependent women. This research was conducted using a descriptive method at the Alcohol-Substance Research, Treatment and Education Center (ASRTEC). The research sample comprised 126 women who presented at ASRTEC clinic between September 15, 2006 and March 15, 2007, and were diagnosed as being alcohol/drug dependent according to DSM-IV. The data were collected using an Addicted Women's Genitourinary Health Evaluation Form and the Arizona Sexual Experiences Scale. In this study 37.3% of the women were alcohol dependent and 62.7% were substance dependent. It was determined that alcohol and other psychoactive substance-dependent women experience a high rate of genitourinary health problems, such as unprotected sexual intercourse with multiple partners, irregular menstrual cycles, sexual dysfunction, unwanted pregnancies, and abortions.</
