#1
Bartosz Tylkowski, Renata Jastrząb
Ground and especially drinking water could be contaminated by heavy metal ions such as lead and chromium, or the metalloid arsenic, discarded from industrial wastewater. These heavy metal ions are regarded as highly toxic pollutants which could cause a wide range of health problems in case of a long-term accumulation in the body. Thus, there have been many efforts to reduce the concentration of lead ions in effluent wastewater. They have included the establishment of stringent permissible discharge levels and management policies, the application of various pollution-control technologies, and the development of adsorbent materials for lead reduction...

The field of laparoscopic surgery has continued to grow exponentially over the years, prompting new innovative technologies. Despite substantial advancements, standard laparoscopic tools have undergone little design changes and fail to optimize mobility in limited spaces. Advancements in robotics have attempted to address this, allowing for increasing degrees of freedom and articulation of instruments. Even so, this system has proven to be cumbersome with questionable cost-effectiveness. In this study, we present the first use of a solely mechanical intuitively controlled articulating laparoscopic needle driver...

Anaplastic thyroid cancer (ATC) is the most aggressive malignancy of the thyroid, during which undifferentiated tumors arise from the thyroid follicular epithelium. ATC has a very poor prognosis due to its aggressive behavior and poor response to conventional therapies. Gene-directed enzyme/prodrug therapy using genetically engineered mesenchymal stromal cells (MSC) is a promising therapeutic strategy. The doxycycline (DOX)-controlled Tet inducible system is the most widely utilized regulatory system and could be a useful tool for therapeutic gene-based therapies...

The goal of this work is to develop an innovative method that combines bioprinting and endoscopic imaging to repair tympanic membrane perforations (TMPs). TMPs are a serious health issue because they can lead to both conductive hearing loss and repeated otitis media. TMPs occur in 3 to 5% of cases after ear tube placement as well as in cases of acute otitis media (the second most common infection in pediatrics), chronic otitis media with or without cholesteatoma, or as a result of barotrauma to the ear. About 55,000 tympanoplasties, the surgery performed to reconstruct TMPs, are performed every year and the commonly used cartilage grafting technique has a success rate between 43% to 100%...
