L. is recognized for its adaptogenic properties and ability to promote muscle health, function and recovery from exercise. The plethora of biological effects of this plant is ascribed to the synergism existing among the molecules composing its phytocomplex. In this manuscript, we analyze the activity of a bioactive fraction extracted from L. controlled cultivation. Biological assays were performed on human skeletal myoblasts and revealed that the extract is able to modulate in vitro expression of transcription factors, namely Pax7 and myoD, involved in muscle differentiation and recovery. The extract also promotes ROS scavenging, ATP production and mitochondrial respiration. Untargeted metabolomics further reveals that the mechanism underpinning the plant involves the synergistic interconnection between antioxidant enzymes and the folic/acid polyamine pathway. Finally, by examining the phytochemical profiles of the extract, we identify the specific combination of secondary plant metabolites contributing to muscle repair, recovery from stress and regeneration.

With the widespread use of typical antibiotics such as sulfamethazine (SMT), it leads to their accumulation in the environment, increasing the risk of the spread of antibiotic resistance genes (ARGs). Aerobic granular sludge (AGS) has shown great potential in treating antibiotic wastewater. However, the long cultivation period of AGS, the easy disintegration of particles and the poor stability of degradation efficiency for highly concentrated antibiotic wastewater are still urgent problems that need to be solved, and it is important to explore the migration and changes of ARGs and microbial diversity in AGS systems.

The first-line treatment for chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) has recently undergone major changes, and targeted therapies have ushered in a new era of CLL/SLL treatment. Scientists in different countries have successively analyzed the efficacy of various drugs, but safety studies are relatively insufficient. Therefore, this systematic evaluation and retrospective meta-analysis was conducted to compare the differences in adverse effects and their incidence among first-line treatment regimens for CLL/SLL.

Background: Nuclear medicine is an interdisciplinary field that integrates basic science with clinical medicine. The traditional classroom teaching model lacks interactive and efficient teaching methods and does not adequately address the learning needs and educational goals associated with standardized training for residents. The teaching model that combines Small Private Online Courses (SPOCs) with a flipped classroom approach is more aligned with the demands of real-life scenarios and workplace requirements, thereby assisting students in developing comprehensive literacy and practical problem-solving skills.

Understanding communication among microorganisms through the array of signal molecules and establishing controlled signal transfer between different species is a major goal of the future of biotechnology, and controlled multispecies bioreactor cultivations will open a wide range of applications. In this study, we used two quorum-sensing peptides from - namely, the competence and sporulation factor (CSF) and (PhrF)-to establish a controlled interkingdom communication system between prokaryotes and eukaryotes. For this purpose, we engineered as a reporter capable of detecting the CSF and PhrF peptides heterologously produced by the yeast .

Long bone and craniofacial bone fractures amount to an overwhelming expenditure for patients and health care systems each year. Overall, 5-10% of all bone fractures result in some form of delayed or nonunion fractures. Nonunions occur from insufficient mechanical stabilization or a compromised wound environment lacking in vasculature and progenitor cells.
