By using long pulses with extended dwelling time, lowered pulse repetition frequency (PRF) and reduced Nyquist velocity, the radar measurement capability can be enhanced to increase clear-air Doppler velocity data coverage (which is beneficial for radar wind analysis and data assimilation and motivated our previous study). This potential capability is further explored (beyond our previous study) by not only modifying the existing operational clear-air scan mode with a lowered PRF and reduced the Nyquist velocity (t [...]

Despite the advances that have been made in the field of solid organ transplant (SOT), organ shortage remains a persistent problem. In addition, the donor pool has been changing with the ongoing opioid epidemic and increase in deaths related to drug overdose each year. More donors are meeting the 2013 United States (U.S.) Public Health Service criteria for increased risk donors (IRDs), or donors who are at higher risk for transmission of Human Immunodeficiency Virus (HIV), Hepatitis C virus (HCV), and other multidr [...]

The urban heat island (UHI) effect is not well understood, especially within the cityscape. This editorial is from the perspective of an undergraduate student Cadet Emma Larsen, as she comes to understand the UHI through mentorship from professors Simon Ghanat and Scott Curtis, personal experiences as a cadet at a military academy in Charleston, SC, USA, and active learning through participation in a national heat observation campaign, the NOAA HeatWatch, and related independent research. HeatWatch seeks to underst [...]

We describe the clinical case of a 74-year-old male patient who received the second Comirnaty/Pfizer anti-COVID-19 vaccine dose. After 3 weeks he showed the clinical signs of polymyalgia rheumatica. The history included mild chronic normocytic normochromic anemia and hypogammaglobulinemia, osteoarthritis disease, livedo reticularis, hypercholesterolemia, and arterial hypertension. Despite prolonged treatment with NSAIDs and dexamethasone, the disease evolved into remitting seronegative symmetrical synovitis with pi [...]

Cryptic balanced chromosomal aberrations can be an underlying cause of infertility. In 2003 Cockwell and coworkers highlighted the relevance of euchromatic pericentric regions of acrocentric chromosomes that may be a yet ignored genomic region hosting cryptic rearrangements. Here we offer the first follow-up study to further explore this idea. Two specific molecular cytogenetic probe sets were established to elucidate such cryptic rearrangements together with chromosomal heteromorphisms of acrocentric centromeres. [...]

The World Health Organization declared the COVID-19 pandemic on March 11th, 2020. The pandemic had significantly affected public health, and the mental health of people was compromised regardless of age or socioeconomic status. In this study, we measured the psychological distress caused by the pandemic and determined the associated factors. An online survey was conducted from November 16th (2020) to January 31st (2021). The participants were Albanian adults (≥18 years old). The call to participate was poste [...]

Background: Cell encapsulation technology is most likely the ultimate solution for cell therapy based clinical approaches. A key issue when developing a functional encapsulated construct is to consider not only the nature of the capsule but also how the cells should be incorporated into the capsule in order to minimally compromise their function. Methods: We have developed a tissue engineering approach, composed of decellularized micro scaffolds and various types of cells in which fully functional "Engineered Micro [...]

A boundless spectrum of chronic lung diseases is said to effect over 500 million persons globally. Lung transplantation is a well-established therapeutic option for patients suffering from end-stage lung diseases, however waitlist mortality and primary graft failure remain major determinants as post-transplantation 5-year survival is just above 50 percent. Recent innovations in lung transplantation have been aimed at increasing organ availability, improving allograft quality, function, and longevity. Ex-vivo Lung P [...]

Acute pancreatitis still represents a challenge for physicians; it ranges from mild self-limiting forms Walled-off necrosis (WON), previously called by other names, such as organized pancreatic necrosis, necroma, pancreatic sequestration, pseudocyst associated with necrosis and subacute pancreatic necrosis is a new entity of complications of acute pancreatitis. It is defined as a mature, encapsulated collection of pancreatic and/or peripancreatic necrosis which has developed a well-defined inflammatory wall. WON us [...]

Hematopoietic stem cell transplantation (HSCT) or Bone Marrow Transplantation (BMT) has significantly improved the survival rates of patients suffering from hematological malignancies. However, the cure can only be achieved at the price of morbidity and long-term complications such as bone diseases leading to fractures and osteopenia. Several studies have reported the impact of organ transplants on bone metabolism, electrolytes and blood profile. This prospective observational clinical study aims at elucidating the [...]
