Effects of Clausena lansium leaves volatile oil emulsion against Staphylococcus aureus in mice via autophagy modulation.

Background: Volatile oil from fresh Clausena lansium (Lour.) Skeels (Rutaceae) (common name Wampee) has been previously extracted by our group from fresh C. lansium leaf and its components were qualitative and quantitatively analyzed by GC-MS.

The effect and mechanism of volatile oil emulsion from leaves of (Lour.) Skeels on .

This study aimed to develop a suitable dosage form of volatile oil from wampee leaves and to explore its antibacterial mechanism . The chemical composition of the volatile oil from wampee leaves was determined by gas chromatography-mass spectrometry (GC-MS). Different microemulsion ratios were tested and their stabilities were investigated to determine the optimal ratio.

Three different routes of EHEC O157:H7 infection were used to establish EHEC broiler model.

In order to study the prevention and control EHEC disease measures in poultry, the infection process and development of this disease and the pathological changes of various organs were to be observed. In this study, chickens were infected with different doses of enterohemorrhagic Escherichia coli (EHEC) O157:H7 using different routes of administration to establish EHEC broiler model. A total of 195 14-day-old broilers were randomly divided into 13 groups: including control group, Enema-drip groups (10, 10, 10, 10 CFUs E.

Resveratrol inhibits oxidative damage in lungs of heat-stressed broilers by activating Nrf2 signaling pathway and autophagy.

The purpose of this study was to investigate the effects of resveratrol on heat stress-induced lung injury in broilers and the mechanism underlying this process. Sixty two-week-old SPF BWEL broilers were randomly divided into the heat stress group (HS), resveratrol group (heat stress + 400 mg/kg resveratrol), and the control group after one week of feeding, with 20 chickens in each group. Broilers in the control group were reared at 23 ± 2 ℃.

Acetaminophen-induced hepatotoxicity predominantly via inhibiting Nrf2 antioxidative pathway and activating TLR4-NF-κB-MAPK inflammatory response in mice.

To explore the action time and molecular mechanism underlying the effect of acetaminophen (APAP) on liver injury. APAP was used to establish drug-induced liver injury (DILI) model in mice. Mice in the model group were intraperitoneally injected 300 mg/kg APAP for 6, 12, and 24 h respectively, and control group mice were given the same volume of normal saline.

Resveratrol relieves chronic heat stress-induced liver oxidative damage in broilers by activating the Nrf2-Keap1 signaling pathway.

Heat stress (HS) affects poultry production and welfare, causing enormous damage to poultry. Resveratrol, an antioxidant and anti-inflammatory natural plant polyphenol, is widely used in agriculture for the prevention of oxidative stress-related diseases. This study aimed to explore the effects and potential mechanism of resveratrol on liver oxidative damage in heat-stressed broilers.

Yinhuang oral liquid protects acetaminophen-induced acute liver injury by regulating the activation of autophagy and Nrf2 signaling.

This study aimed to investigate the protective effect and potential mechanism of Yinhuang oral liquid (YOL) against acetaminophen (APAP) induced liver injury in mice. C57BL/6 mice were randomly divided into control group, model group (300 mg/kg APAP), NAC group and YOL group. Mice were treated intragastrical with YOL (8 g/kg) and N-Acetylcysteine (NAC, 300 mg/kg) 6 h before and 6 h after the APAP (300 mg/kg) intraperitoneal injection.

Heat stress in broilers of liver injury effects of heat stress on oxidative stress and autophagy in liver of broilers.

This study aimed to investigate the effect of chronic heat stress on oxidative stress in liver of broilers. In our study, chickens were randomly allocated to control 1 group (control 7 d), heat stress 1 group (HS1, 7 d), control 2 group (control 14 d) and heat stress 2 group (HS2, 14 d), with 30 replicates in each group. Broilers in heat stress groups exposed 8 h/day heat stress (35 ± 2°C) for 7 or 14 consecutive days, and the rest of time per day were kept at 23 ± 2℃ the same as control group broilers.

An special epithelial staining agents: folic acid receptor-mediated diagnosis (FRD) effectively and conveniently screen patients with cervical cancer.

High-quality screening with cytology has markedly reduced mortality from cervical cancer. However, it needs experienced pathologists to review and make the final decisions. We have developed folic acid receptor-mediated diagnosis (FRD) kits to effectively and conveniently screen patients with cervical cancer.
