The objective of this study was to examine the residue elimination patterns of seven antibiotics in the eggs of Taihang chickens under free-range conditions and develop suitable withdrawal times (WDTs). A total of 240 healthy Taihang chickens, aged 180 days, were randomly divided into eight groups of 30 birds each. The first seven groups were administered oxytetracycline, chlortetracycline, erythromycin, tylosin, tylvalosin, lincomycin, and tiamulin, respectively, in accordance with the maximum dosages and longest durations of treatment recommended by the Veterinary Pharmacopoeia of the People's Republic of China.

Background: Peripheral nerve injury (PNI) is a common clinical problem that can result in partial or complete loss of sensory, motor, and autonomic functions. Tetrahydropalmatine (THP), a Corydalis yanhusuo-derived phytochemical alkaloid, possesses hypnotic, soothing, analgesic, and other effects, but little is known about the effect of THP on moderating peripheral nerve regeneration and its possible underlying mechanism of action.

Purpose: In this study, we aim to elucidate the protective function of THP on PNI and further reveal the underlying pharmacological mechanisms.

Granulomas, dense clusters of immune cells and bacteria, are critical barriers in tuberculosis (TB) treatment. Recent advancements in TB management have highlighted granuloma control as a potential host-directed therapy (HDT) strategy. Although isoniazid (INH) is the first-line drug for TB therapy, its efficacy is limited to non-replicating Mycobacterium tuberculosis (Mtb) under granulomatous conditions, necessitating the development of more effective derivatives.

Intern Emerg Med

January 2025

Department of Social and Behavioral Sciences, School of Global Public Health, New York University, New York, NY, USA.

Article Synopsis
  • A recent CDC survey analyzed methods used by US adults to stop smoking, showing that around 2.9 million adults successfully quit for at least 6 months in the last year.
  • Most successful quitters were younger, educated, male, non-Hispanic White, and commonly used nicotine products, especially e-cigarettes, compared to less popular options like prescription drugs.
  • The study highlights that many adults still try to quit smoking without support, suggesting a need for targeted interventions to help those who struggle the most in quitting, using proven methods.

Biofilm battle: New transformative tactics to tackle the bacterial biofilm infections.

Microb Pathog

February 2025

Department of Biotechnology, National Institute of Technology, Raipur, 492010, (CG), India. Electronic address:

Bacterial biofilm infections are the root cause of persistent infections and the prevalence of resistance to specific or multiple antibiotics. Biofilms have unique features that provide a protective environment for bacteria under various stress conditions and contribute significantly to the pathogenesis of chronic infections. They cover bacterial cells with a self-produced extracellular polymeric matrix, effectively hiding the bacterial cells and their targets.

Effect of intramuscular treatment with different iron dextran dosages and non-inferiority study to gleptoferron.

Acta Vet Scand

January 2025

Department of Veterinary and Animal Sciences, Faculty of Health and Medical Sciences, University of Copenhagen, Grønnegårdsvej 2, 1870, Frederiksberg C, Denmark.

Background: Prevention of iron deficiency in suckling piglets by intramuscular injection of a standardized amount of iron dextran or gleptoferron in the first days of life can lead to over- or underdosage with respective health risks. Currently, combined iron products containing an active substance against coccidia are also used on farms. When using a combination product targeting two diseases, an adjustment of the necessary amount of iron to prevent anaemia in the frame of a farm-specific treatment protocol is not possible.

Obesity-induced muscle alterations, such as inflammation, metabolic dysregulation, and myosteatosis, lead to a decline in muscle mass and function, often resulting in sarcopenic obesity. Currently, there are no definitive treatments for sarcopenic obesity beyond lifestyle changes and dietary supplementation. Feruloylacetone (FER), a thermal degradation product of curcumin, and its analog demethoxyferuloylacetone (DFER), derived from the thermal degradation of bisdemethoxycurcumin, have shown potential antiobesity effects in previous studies.

Salinity stress disrupts water uptake and nutrient absorption, causing reduced photosynthesis, stunted growth, and decreased crop yields in plants. The use of indole acetic acid (IAA), arginine (AN), and mango fruit waste biochar (MFWB) can be effective methods to overcome this problem. Indole acetic acid (IAA) is a natural auxin hormone that aids cell elongation and division, thereby increasing plant height and branching.

We performed a systems vaccinology analysis to investigate immune responses in humans to an H5N1 influenza vaccine, with and without the AS03 adjuvant, to identify factors influencing antibody response magnitude and durability. Our findings revealed a platelet and adhesion-related blood transcriptional signature on day 7 that predicted the longevity of the antibody response, suggesting a potential role for platelets in modulating antibody response durability. As platelets originate from megakaryocytes, we explored the effect of thrombopoietin (TPO)-mediated megakaryocyte activation on antibody response longevity.

Preliminary report: Protective effects of probiotics on cefovecin-induced gut dysbiosis in dogs.

Can J Vet Res

January 2025

Laboratory of Veterinary Dermatology (Han, Hwang) and Research Institute for Veterinary Science (Han, Mun, Hwang), College of Veterinary Medicine, Seoul National University, Seoul, Republic of Korea; ORIGIN Veterinary Dermatology Clinic, Busan, Republic of Korea (Kang); Department of Companion Animal Health Care, College of Medical Health, Kyungbok University, Namyangju, Republic of Korea (Kim S-J); Department of Large Animal Internal Medicine, College of Veterinary Medicine, Kangwon National University, Chuncheon, Republic of Korea (Kim Y-H).

The objective of this study was to evaluate whether supplementation with probiotics over a 2-week period stabilizes the gut microbiota in dogs following prolonged cefovecin treatment. A significant number of clinical veterinarians prescribe oral probiotics to dogs in conjunction with systemic antibiotics with the intention of protecting against gut dysbiosis. The effects of antibiotics and probiotics in dogs have not been extensively studied, however, and the optimal treatment for gut dysbiosis remains uncertain.

A surface protein identified from Streptococcus suis serotype 2 exhibits neutrophil-resistant ability via its polysaccharide capsule.

Microb Pathog

February 2025

MOE Joint International Research Laboratory of Animal Health and Food Safety, College of Veterinary Medicine, Nanjing Agricultural University, Nanjing, 210095, PR China; College of Animal Science, Anhui Science and Technology University, Fengyang, 233100, PR China. Electronic address:

Article Synopsis
  • Streptococcus suis serotype 2 (SS2) is a zoonotic bacteria that can cause serious diseases, but how it avoids the body's immune system is not well understood.
  • A study identified a specific protein mutation in SS2 that leads to increased neutrophil responses, yet the mutated bacteria survive poorly in the bloodstream compared to the original strain.
  • The deletion of this protein results in a weaker protective capsule and boosts the bacteria's ability to form biofilms; however, it also decreases the bacteria's survival within immune cells, highlighting potential targets for preventing infections.

Obstructive sleep apnea (OSA) is widespread, under-recognized, and under-treated, impacting the health and quality of life for millions. The current gold standard for sleep apnea testing is based on the in-lab sleep study, which is costly, cumbersome, not readily available and represents a well-known roadblock to managing this huge societal burden. Assessment of neuromuscular function involved in the upper airway using electromyography (EMG) has shown potential to characterize and diagnose sleep apnea, while the development of transmembranous electromyography (tmEMG), a painless surface probe, has made this opportunity practical and highly feasible.
