Objectives: The role of infection in the pathogenesis of atherosclerosis has been increasingly discussed. Previous studies have suggested that increased myeloperoxidase activity plays an important role in the pathogenesis of atherosclerosis. The aim of this study was to investigate the serum myeloperoxidase activity and catalase activity along with lipid hydroperoxide (LOOH) levels in patients with acute brucellosis.

Design And Methods: Thirty-two patients with brucellosis and 33 healthy controls were enrolled. Serum myeloperoxidase activity, catalase activity and LOOH levels were determined.

Results: Serum myeloperoxidase activity and LOOH levels were significantly higher in patients with brucellosis than controls (p<0.05, p<0.001), while catalase activity were significantly lower (p<0.001). LOOH levels were found to be significantly positively correlated with MPO activity (r=0.297, p=0.016) in patients.

Conclusions: These results indicate that increased myeloperoxidase activity and decreased catalase activity is associated with increased oxidative stress, which may have a role in atherosclerotic processes in brucellosis patients.

Bamboo powder, a novel ingredient, is gaining recognition for its potential as a dietary supplement in poultry feed. This study aimed to investigate the effects of fermented bamboo powder (FBP) on antioxidant status, gut hormone activities, intestinal digestive enzyme activities, gut morphological structure, gastrointestinal development, and the expression of nutritional transporter genes in dwarf yellow-feather broiler chickens. A total of 600 healthy 1-day-old chicks were allocated randomly into two groups, with 10 replicates per group and 30 chicks in each replicate.

With rising concerns about antibiotic resistance and its consequences on public health, the identification of safe and effective alternatives to antibiotics in the poultry industry has become increasingly critical. This study aimed to evaluate the effects of supplementing drinking water with apple vinegar and essential oils, compared to an antibiotic growth promoter, on the growth performance, serum lipid profile, antioxidant status, intestinal morphology, and gastrointestinal microflora population of broiler chickens. A total of 240 one-day-old male broiler chickens were randomly assigned to four treatments, each consisting of six replicate pens with ten birds per pen.

Background: Sepsis-induced acute lung injury (ALI) is a severe clinical condition accompanied with high mortality. Tangeretin, which is widely found in citrus fruits, has been reported to exert antioxidant and anti-inflammatory properties. However, whether tangeretin protects against sepsis-induced ALI and the potential mechanisms remain unclear.

The JAZ protein family, serving as a key negative regulator in the jasmonic acid signaling pathway, interacts with transcription factors to play an essential role in plant growth, development, and stress responses. However, minimal research has focused on the role of JAZ transcription factors in regulating the growth, development, and stress responses of maize. In this study, we cloned the JAZ gene ZmJAZ13 from maize (Zea mays L.
