Demonstrating biosimilarity entails comprehensive analytical assessment, clinical pharmacology profiling, and efficacy testing in patients for at least one medical indication, as required by the U.S. Biologics Price Competition and Innovation Act (BPCIA). The efficacy testing can be waived if the drug has known pharmacodynamic (PD) markers, leaving most therapeutic proteins out of this concession. To overcome this, the FDA suggests that biosimilar developers discover PD biomarkers using omics technologies such as proteomics, glycomics, transcriptomics, genomics, epigenomics, and metabolomics. This approach is redundant since the mode-action-action biomarkers of approved therapeutic proteins are already available, as compiled in this paper for the first time. Other potential biomarkers are receptor binding and pharmacokinetic profiling, which can be made more relevant to ensure biosimilarity without requiring biosimilar developers to conduct extensive research, for which they are rarely qualified.

Introduction: Toxocarosis in human beings is currently diagnosed by serological assay based on the detection of antibodies against Toxocara antigens. Toxocara canis larvae do not reach the adult stage in paratenic hosts like humans and mice. Therefore experimental infection in mice, which mimics the biology of human infection, might be relevant to get a better understanding of human toxocarosis.

Micro-osteoperforations and corticotomies are two surgical techniques commonly used to increase the rate of tooth movement. The aim of this systematic review was to respond to the question: Which method used for accelerating orthodontic tooth movement, micro-osteoperforations or alveolar corticotomy, produces a higher rate of tooth movement and present less adverse effects? Searches were performed in the electronic databases of PubMed, Scopus, Cochrane CENTRAL, Web of Science, Lilacs and Science Direct, as well as grey literature (Opengrey), up to March 2024. All the included studies were controlled, randomized clinical trials, cohort, case-control, cross-sectional, and multicentre studies of patients treated with orthodontics and corticotomies or micro-osteoperforations.

Ethnopharmacological Relevance: The Chinese medicine sappanwood is primarily sourced from the dried heartwood of the medicinal plant Caesalpinia sappan Linn., which has been found with a variety of valuable properties including anti-inflammatory, anti-oxidant, and anti-viral effects. Preliminary investigations have demonstrated that sappanwood showed strong anti-SARS-CoV-2 M effects, but the key constituents responsible for SARS-CoV-2 M inhibition and their anti-M mechanisms have not been uncovered.

Ethnopharmacological Relevance: Jieyu I Formula (JY-I) is an improved version of the classic formula "Sini San" documented in the books Shanghan Lun, which is known for regulating the liver and treating depression. However, the disturbance of neuronal signal transmission in the neural circuit of the brain is closely related to the occurrence of depression, yet its neural mechanism is still unclear.
Aim Of The Study: This study aimed to observe the antidepressant effect of JY-I on depressed mice induced by lipopolysaccharide and its underlying central nervous system mechanisms, focusing on the prefrontal cortex (PFC) to lateral habenular nucleus (LHb) neural circuit in the depressed mice model.

This study was designed to evaluate the combined antimicrobial activity of selected phage cocktail (MS2+T7 phages) and essential oils (cinnamon, clove, oregano, and thymol) against Escherichia coli ATCC 15597. To select most effective phages, the lytic abilities of individual phages (MS2, phiX174, and T7) and their phage combinations were assessed using the phage spot test and plaque assay at various multiplicity of infections (MOIs) ranging from 0.01 to 100.
