Thoracolumbar fascia ultrasound shear strain differs between low back pain and asymptomatic individuals: expanding the evidence.

Objectives: To compare thoracolumbar fascia (TLF) shear strain between individuals with and without nonspecific low back pain (NSLBP), investigate its correlation with symptoms, and assess a standardized massage technique's impact on TLF shear strain.

Methods: Participants were prospectively enrolled between February 2021 and June 2022. Pre- and post-intervention TLF ultrasound and pain/disability questionnaires were conducted.

Low Prevalence of SARS-CoV-2 in Farmed and Free-Ranging White-Tailed Deer in Florida.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been detected in multiple animal species, including white-tailed deer (WTD), raising concerns about zoonotic transmission, particularly in environments with frequent human interactions. To understand how human exposure influences SARS-CoV-2 infection in WTD, we compared infection and exposure prevalence between farmed and free-ranging deer populations in Florida. We also examined the timing and viral variants in WTD relative to those in Florida's human population.

Detection of SARS-CoV-2- specific antibodies in domestic cats using different ELISA tests.

The emergence of SARS-CoV-2 raised concerns about the potential for interspecies transmission, particularly among domestic animals. We evaluated the seroprevalence of SARS-CoV-2 antibodies in domestic cats from various sites in North America. A total of 216 serum samples collected between December 2019 and February 2022, were analyzed using four different enzyme-linked immunosorbent assays (ELISAs), including a commercial surrogate virus neutralization test (sVNT), a commercial double antigen test (dN ELISA), and two in-house developed indirect ELISAS based on receptor-binding domain (RBD iELISA) and the nucleocapsid (N iELISA) proteins, respectively.

Cattle, sheep, and goat humoral immune responses against SARS-CoV-2.

Following the emergence of SARS-CoV-2 in late 2019, several species of domestic and wild animals have been found to be susceptible to SARS-CoV-2 infection through experimental inoculation and animal surveillance activities. Detection of SARS-CoV-2 specific antibodies in animals is an important surveillance tool since viral shedding in animals can only be detected for a short period of time. In this study, convenience serum samples were collected from 691 cattle, 698 sheep, and 707 goats from several regions in the United States, between 2019 and 2022.

Generation and Genetic Stability of a PolX and 5' MGF-Deficient African Swine Fever Virus Mutant for Vaccine Development.

The African swine fever virus (ASFV) causes fatal disease in pigs and is currently spreading globally. Commercially safe vaccines are urgently required. Aiming to generate a novel live attenuated vaccine (LAV), a recombinant ASFV was generated by deleting the viral O174L (PolX) gene.
