Biosynthesis of Bt-AgO nanoparticles using Bacillus thuringiensis and their pesticidal and antimicrobial activities.

Nanosilver oxide exhibits strong antibacterial and photocatalytic properties and has shown great application potential in food packaging, biochemical fields, and other fields involving diseases and pest control. In this study, AgO nanoparticles were synthesized using Bacillus thuringiensis (Bt-AgO NPs). The physicochemical characteristics of the Bt-AgO NPs were analyzed by UV‒vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM), inductively coupled plasma emission spectrometry (ICP), high-resolution transmission electron microscopy (HR-TEM), and zeta potential.

Microencapsulation of Capsaicin in Chitosan Microcapsules: Characterization, Release Behavior, and Pesticidal Properties against (Herbst).

Capsaicin is a capsaicinoid in hot chili peppers, with excellent antibacterial and antimicrobial activities and a good safety profile, but its poor solubility and instability restrict its effectiveness. This limitation may be mitigated by encapsulation. Herein, capsaicin microcapsules (CCMs) were prepared through layer-by-layer self-assembly, using chitosan and carboxymethyl chitosan as shell materials.

Acupuncture for chronic constipation in patients with diabetes mellitus: A protocol for systematic review.

Background: Assessing the effectiveness and safety of acupuncture for chronic constipation in patients with diabetes mellitus is the main purpose of this systematic review protocol.

Methods: The following electronic databases will be searched from their respective inception dates to December 1st 2020: PubMed, the Cochrane Library, Embase, World Science Net, the Allied and Complementary Medicine Database, the Web of Science, China National Knowledge Infrastructure, the Chongqing VIP Chinese Science and Technology Periodical Database and the Wanfang Database. All published randomized controlled trials in English or Chinese related to acupuncture for constipation in patient with diabetes mellitus will be included.

Inhibition of mitochondrial respiration under hypoxia and increased antioxidant activity after reoxygenation of Tribolium castaneum.

Regulating the air in low-oxygen environments protects hermetically stored grains from storage pests damage. However, pests that can tolerate hypoxic stress pose a huge challenge in terms of grain storage. We used various biological approaches to determine the fundamental mechanisms of Tribolium castaneum to cope with hypoxia.

Comparative metabolomics analysis of Callosobruchus chinensis larvae under hypoxia, hypoxia/hypercapnia and normoxia.

Background: Insect tolerance to low oxygen (hypoxia) and high carbon dioxide (hypercapnia) is critical for insect control. On the basis of bioassay, metabolism profiles were built to investigate adaptive mechanisms in bean weevil under hypoxia (2% O ), hypoxia/hypercapnia (2% O + 18% CO ) and normoxia (control, 20% O + 80% N ) using gas chromatography/time-of-flight mass spectrometry (GC/TOF-MS).

Results: The growth and development of bean weevils were significantly suppressed by the two hypoxia conditions; hypercapnia enhanced the mortality, but after 24 days of exposure, the surviving insects emerged as adults earlier than those under hypoxia only.

[Detection and analysis of HAV-HEV, HGV infection in patients with viral hepatitis].

Objective: To study the simple infection and super/co-infection of HAV-HEV, HGV in patients with viral hepatitis.

Methods: Using EIA method to detect anti-HAV IgM, HBV serum markers, anti-HCV IgM, anti-HDV IgM, anti-HEV IgM, anti-HGV IgM in viral hepatitis patients with different clinical types.

Results: Seventy-three percent patients (154/210) had HBV infection markers, twenty-nine percent patients (61/210) had HAV infection marker, eight percent patients (17/210) had HCV, HDV infection markers, ten percent patients (21/210) had HEV infection and seven percent patients (15/210) had HGV infection.

[Relationship between hepatitis G virus infection and hepatic failure].

Objective: To study the pathogenic effect of hepatitis G virus (HGV) infection on hepatic failure.

Methods: Using the RT-PCR and EIA techniques to detect HGV RNA and anti-HGV in sera of hepatic failure patients and compare them with their liver function and mortality rates.

Results: There was no significant difference about the positive rates of HGV among acute hepatic failure, subacute hepatic failure and chronic hepatic failure groups (X(2)=2.
