Toxoplasmosis is a parasitic disease caused by the protozoan that is highly prevalent worldwide. Although the infection is asymptomatic in immunocompetent individuals, it severely affects immunocompromised individuals, causing conditions such as encephalitis, myocarditis, or pneumonitis. The limited therapeutic efficacy of drugs currently used to treat toxoplasmosis has prompted the search for new therapeutic alternatives. The aim of this study was to determine the anti- activity of extracts obtained from two species of the genus . Twenty-six extracts, 12 obtained from and 14 from , were evaluated by a colorimetric technique using the RH strain of that expresses β-galactosidase. Additionally, the activity of the promising extracts and their active compounds was evaluated by flow cytometry. β-amyrin was isolated from the chloroform extract obtained from the leaves of and displayed important anti- activity. The results show that natural products are an important source of new molecules with considerable biological and/or pharmacological activity.

The tendon-bone interface, known as the tenosynovial union or attachment, can be easily damaged by excessive exercise or trauma. Tendon-bone healing is a significant research topic in orthopedics, encompassing various aspects of sports injuries and postoperative recovery. Surgery is the most common treatment; however, it has limited efficacy in promoting tendon-bone healing and carries a risk of postoperative recurrence, necessitating the search for more effective treatments.

For patients considering bariatric surgery, it is essential to have clear answers to common questions to ensure the success of the procedure. Patients should understand that surgery is not a quick fix but a tool that must be complemented by lifestyle changes, including dietary adjustments and regular physical activity. The procedure carries potential risks that should be weighed against the potential benefits.

Background: Pain is a major challenge for patients with rheumatoid arthritis (RA), with many people suffering chronic pain. Current RA management guidelines focus on assessing and reducing disease activity using disease-modifying anti-rheumatic drugs (DMARDs). Consequently, pain care is often suboptimal, with growing evidence that analgesics are widely prescribed to patients with RA, despite potential toxicities and limited evidence for efficacy.

Animals infected with mycoplasma pneumoniae not only develop respiratory diseases, but also cause digestive diseases through the lung-gut axis mediated by the intestinal flora, and vice versa. Antimicrobial peptides are characterized by their bactericidal, anti-inflammatory, and intestinal flora-regulating properties. However, the effect of cecropin AD (CAD) against mycoplasma pneumonia remains unclear.

Background: Enterovirus 71 (EV71) is one of the major causative agents of hand, foot, and mouth disease (HFMD), and can cause severe cerebral complications and even fatality in children younger than 5 years old. However, there is no specific medication for EV71 infection in clinical practice. Our previous studies had identified the 6-thioguanine (6-TG), an FDA-approved anticancer drug, as a potential antiviral agent, but its anti-EV71 activity is largely unknown, therefore, we aim to explore the antiviral effect of 6-TG on EV71.
