Synergistic Photothermal Tumor Immunotherapy by 1-MT Based on Zeolitic Imidazolate Framework-8 with pH-High Sensitivity.

Background: A successful immune response against tumors depends on various cellular processes. Hence, there is an urgent need to construct a proficient nanoplatform for immunotherapy that can concurrently regulate the activities of various cells participating in the immune process. We have developed zeolitic imidazolate framework-8 (ZIF-8) formula, with good pH sensitivity, which is conducive to the release of drugs in the tumor site (acidic environment) and significantly improves immunotherapy.

Remediation of cadmium contaminated soil using electrokinetic-phytoremediation system with rotary switching electrodes.

Considering both electrokinetic remediation and phytoremediation have limitations, an electrokinetic phytoremediation (EP) system was constructed to obtain efficient and environmentally friendly remediation results. This study indicates that the electric field can promote the absorption of Cd by ryegrass with little impact on soil physicochemical properties under the condition of rotary switching electrodes, and the accumulation of Cd in the aboveground and underground parts of ryegrass increased by 145.2% and 93.

UiO-66 nanoparticles combat influenza A virus in mice by activating the RIG-I-like receptor signaling pathway.

The Influenza A virus (IAV) is a zoonotic pathogen that infects humans and various animal species. Infection with IAV can cause fever, anorexia, and dyspnea and is often accompanied by pneumonia characterized by an excessive release of cytokines (i.e.

Gut commensal bacteria exacerbate toxoplasmosis associated with TgSheepCHn5 (ToxoDB#2) and TgRedpandaCHn1 (ToxoDB#20) through Th1 immune response.

Oral infection of mice with several strains of Toxoplasma gondii results in intestinal pathological lesions, which contributes to the invasion of this parasite. However, the exact mechanism is unclear, and only a few strains have been explored. Here, T.

Melatonin alleviates lung injury in H1N1-infected mice by mast cell inactivation and cytokine storm suppression.

Influenza A virus (IAV) H1N1 infection is a constant threat to human health and it remains so due to the lack of an effective treatment. Since melatonin is a potent antioxidant and anti-inflammatory molecule with anti-viral action, in the present study we used melatonin to protect against H1N1 infection under in vitro and in vivo conditions. The death rate of the H1N1-infected mice was negatively associated with the nose and lung tissue local melatonin levels but not with serum melatonin concentrations.

PI3K/AKT-mediated autophagy inhibition facilitates mast cell activation to enhance severe inflammatory lung injury in influenza A virus- and secondary Staphylococcus aureus-infected mice.

Influenza A virus infection causes considerable morbidity and mortality each year globally, and secondary bacterial infection further exacerbates the severity and fatality of the initial viral infection. Mast cells have substantial roles in protecting the respiratory tract mucosa, while their role in viral and bacterial co-infection remains unclear. The present study revealed that secondary Staphylococcus aureus infection significantly aggravated the activation of mast cells during the initial H1N1 infection both in vivo and in vitro, which was closely related to the increased inflammatory lung injury and mortality.

Low Prevalence of Antibodies Against in Chinese Populations.

has been found to infect almost all warm-blooded animals, including humans. In this study, a total of 3,275 human serum samples were collected from hospitals in five provinces of China. About 5.

Toxoplasma gondii in lambs of China: Heart juice serology, isolation and genotyping.

Toxoplasmosis is one of the most common foodborne diseases in the world. The objective of this study was to determine Toxoplasma gondii infection in lambs from Henan province, China. A total of 166 lamb hearts were collected from 2017 to 2019.

Low prevalence of viable Toxoplasma gondii in swine from slaughter houses in the central of China.

Background: Toxoplasma gondii is widely distributed and can infect many species of warm-blooded animals, including swine. This study aimed to evaluate the prevalence of T. gondii in swines from the central of China.

Direct evidence of an extra-intestinal cycle of in tigers () by isolation of viable strains.

Toxoplasmosis is one of the most common zoonotic diseases in the world. Felines excrete environmentally resistant oocysts. However, there is no direct evidence to prove tigers are the intermediate host of .

Isolation, genotyping and pathogenicity of a Toxoplasma gondii strain isolated from a Serval (Leptailurus serval) in China.

Toxoplasma gondii typically causes lifelong chronic infection and has been identified in a variety of intermediate and definitive hosts. Felids are capable of serving as both intermediate and definite hosts for T. gondii infection.

in four captive kangaroos ( spp.) in China: Isolation of a strain of a new genotype from an eastern grey kangaroo ().

Marsupials are highly susceptible to infection. Here, we report infection in four kangaroos from a zoo in China. Kangaroos were imported into China in 2000 and were since bred in zoo.

Evidence of red panda as an intermediate host of and species.

has been found to infect almost all warm-blooded animals; however, some hosts lack direct evidence of infection. The red panda () is an endangered species that mainly lives in temperate forests of South Asia. Here, infection in red pandas from zoos in China were reported.

Sarcocystis species in wild and domestic sheep (Ovis ammon and Ovis aries) from China.

Background: Sarcocystis species are intracellular protozoan parasites that can pose a threat to animal health and food safety. The aim of this study was to investigate the prevalence of infection with Sarcocystis infection in sheep from China.

Results: In total, 52.

Prevalence, Risk Factors, and Genotypes of in Food Animals and Humans (2000-2017) From China.

as a food-borne pathogen, the infection of it in food animals has relation with human toxoplasmosis, but the trends and epidemiological features of infections in food animals are rarely studied in China. The aimed of this study was to assess the epidemiology and risks of in sheep, goats, swines, chickens, yaks, cattle and humans from 2000 to 2017 and to explore prevention and control strategies. The overall seroprevalence of infections in food animals is 23.

High prevalence of Sarcocystis spp. infections in cattle (Bos taurus) from central China.

Myocardium and diaphragm samples of cattle (n = 521) from HeNan Province (China) were screened for Sarcocystis sarcocysts by histological examination, pepsin digestion, and molecular assays. Morphology and molecular assays were used for identification. The prevalence of Sarcocystis infection in cattle was 41.

Supported cobalt oxide on graphene oxide: highly efficient catalysts for the removal of Orange II from water.

The current paper investigated the removal of the azo dye Orange II from water using advanced oxidation processes based on sulfate radicals. The cobalt oxide catalyst immobilized on graphene oxide (GO) can activate peroxymonosulfate (PMS) for the degradation of Orange II in water. The Co(3)O(4)/GO catalyst system was characterized via X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, and X-ray spectroscopy.

Studies on the properties of graphene oxide-alkaline protease bio-composites.

Graphene oxide (GO) nanosheets as functional material have a unique planar structure and intriguing mechanical that have attracted intensive interests recently. A method was developed for the immobilization protease on GO sheets using glutaraldehyde as cross-linking reagent. The results showed that the thermostability and reusability of immobilized protease have been obviously improved compared to the free enzyme.
