Back propagation artificial neural network (BP-ANN) for prediction of the quality of gamma-irradiated smoked bacon.

This study investigated the effect of gamma irradiation on smoked bacon quality during storage and developed a multi-quality prediction model based on gamma irradiation. Gamma irradiation reduced moisture content and improved the microbial safety of smoked bacon. It also accelerated protein and lipid oxidation and altered free amino acids and fatty acids composition.

The discovery of potentially active diterpenoids to inhibit the pyroptosis from Callicarpa arborea.

Pyroptosis is a programmed-inflammatory cell death, which leads to release of inflammatory cellular contents and formation of inflammation. Uncontrollable pyroptosis can result in serious immune diseases, such as cytokine release syndrome (CRS), sepsis, disseminated intravascular coagulation (DIC), and acute organ damage, including acute respiratory distress syndrome (ARDS) and acute kidney injury (AKI). Members of the Callicarpa genus are significant raw materials for traditional Chinese medicine, widely used for analgesia, hemostasis, and anti-inflammation.

Synthesis and anti-inflammatory evaluation of new chalcone derivatives bearing bispiperazine linker as IL-1β inhibitors.

In this work, a series of novel chalcone derivatives bearing bispiperazine linker have been synthesized and in vitro anti-inflammatory, cytotoxic activity and anti-inflammatory mechanism have been screened. The results indicated that most bispiperazinochalcone derivatives displayed good inhibition of NO (IC < 20 μM) and low cytotoxicity (CC > 40 μM), and selectively inhibited the production of IL-1β via inhibiting NLRP3 inflammasome activation, as promising candidate compounds for the treatment of NLRP3 inflammasome-driven diseases.

Dioscin, a Steroidal Saponin Isolated from Dioscorea nipponica, Attenuates Collagen-Induced Arthritis by Inhibiting Th17 Cell Response.

Dioscin, a steroidal saponin isolated from Dioscorea nipponica Makino, has previously been shown to possess antiarthritic effects. However, the underlying mechanism is still elusive. Herein, we investigated the therapeutic effects of dioscin on collagen-induced arthritis (CIA) in DBA/1 mice and related mechanism.

Gene polymorphisms of DISC1 is associated with schizophrenia: Evidence from a meta-analysis.

Background: Previous studies suggest an association between Disrupted in schizophrenia 1 (DISC1) polymorphisms and schizophrenia (SCZ). However, the available data are often inconsistent, regarding the difference in sample size, ethnicity, genotyping method, etc. Thus, we carried out a meta-analysis to determine whether DISC1 polymorphisms contributed susceptibility to SCZ.

Highly oxygenated lanostane-type triterpenoids and their bioactivity from the fruiting body of Ganoderma gibbosum.

Eight new highly oxygenated lanostane triterpenes, gibbosic acids A-H (1-8), along with three known ones (9-11), were isolated from the fruiting body of Ganoderma gibbosum. The structures of new isolates were assigned by NMR and HRESIMS experiments. The absolute configurations of 1 were further confirmed by single crystal X-ray diffraction data and computational ECD methods.

[Antimicrobial resistance characteristics of and disinfectant-resistant gene distribution in Staphylococcus aureus isolates from male urogenital tract infection].

Objective: To study the antibiotic- and disinfectant-resistance features of and disinfectant-resistant gene distribution in Staphylococcus aureus (Sa) isolated from the urogenital tract of male patients with urogenital tract infection (UTI). total of 152 Sa isolates were collected from the urethral discharge specimens from male UTI patients. The minimum inhibition concentration (MIC) of antimicrobial agents and disinfectants commonly used against Sa were tested by standard ager dilution; the methicillin-resistant Sa (MRSA) isolates detected by cefoxitin disk diffusion and mecA gene amplification; Staphylococcal cassette chromosome mec (SCCmec) genotyping performed by multiplex PCR; the disinfectants gene qac (quaternary ammonium compound) amplified by PCR; and the clonal relatedness of qacA/B-positive MRSA isolates investigated by pulsed-field gel electrophoresis (PFGE).

Impairments of social cues recognition and social functioning in Chinese people with schizophrenia.

Previous studies have suggested that social cognition deficits, and impaired social functioning, were associated with schizophrenia. However, specificity of the relationships between social cues recognition and social functioning remain largely undefined. The authors speculated that the two were related, and further that recognition of verbal and non-verbal social cues were impaired in people with schizophrenia.

Impaired recognition of fear in a Chinese man with bilateral cingulate and unilateral amygdala damage.

LJM, a 41-year-old schizophrenic Chinese man with bilateral anterior cingulate gyrus (Brodmann's area 24) lesions and also a small lesion in right amygdala after an operation, was compared with normal as well as brain-damaged and schizophrenic controls in identification of morphed facial expressions of six basic emotions. In repeated administrations of the test for recognition of facial emotions, over a 1- year period, LJM performed significantly worse for expressions of fear compared with the three groups of controls. Recognition of other emotions was not significantly different from that of the controls, except that his recognition of disgust during the first session (but not in two subsequent sessions) was worse than normal and brain-damaged controls but not worse than schizophrenic controls.
