A study was performed to validate 3 FMDV 3ABC-I-ELISA kits developed in China for the differentiation of FMDV infected and vaccinated animals.Sets of sera from naive and vaccinated cattle as well as from cattle that had been infected were tested for antibodies against nonstructural proteins (NSPs) of FMDV by commercial diagnosis kits,Ceditest(R)FMDV-NS (Ceditest(R) kit),UBI(R) FMDV NONSTRUCTURAL PROTEIN ELISA DIRECTION INSERT (UBI(R) kit) and a FMDV 3ABC-I-ELISA kitdeveloped at the Lanzhou Veterinary Research Institute.The test parameters (sensitivity and specificity) of the three kits were determined,and the result obtained from FMD 3ABC-I-ELISA kit was compared with that obtained from two foreign kits.The results indicated that the coincidence rate between the FMDV 3ABC-I-ELISA and Ceditest(R) kits was 98.05%,and the coincidence rate between the FMDV 3ABC-I-ELISA and UBI(R) kits was 94.4%; the sensitivity of both Ceditest(R) and FMDV 3ABC-I-ELISA kit was 100%.However,the sensitivity of the UBI(R) kit was only 81.8%.With sera from naive or vaccinated non-infected animals,the specificity of all tests exceeded 90%.

Objective To investigate the antitumor immunity induced by tumor derived mixed heat shock protein/peptide(mHSPs),interleukin-12(IL-12)and Cyclophosphamide(Cy).MethodsPurified mixed HSP was prepared from tumor by S180 protein extraction and purification,SDS-PAGE,Western blot and animal experiment were applied for mixed HSPs analysis.ResultsThe proliferation of cytotoxic T lymphocyte(CTL)cocultured in the mHSPs+Cy+IL-12 group was significantly remarkable and the content of CD8+ CTLs was significantly more in comparison with the other groups(P<0.01).To the tumor bearing mice,mHSPs+Cy+IL-12 group showed partial therapeutic efficacy,the averaged survival period was over 60 d,and 90% of the mice in this group got long period tumor free survival(>90d),obvious difference(P<0.05)from the other groups.ConclusionTumor derived mixed HSPs can induce powerful antitumor immune efficacy and show favorable therapeutic efficacy.

Aim: To study the effect of Ureaplasma urealyticum (UU) infection on germ cell apoptosis of male rats. Methods: Male rats were infected artificially with UU serotype 8 (T960) . Morphological changes of germ cells in the seminiferous tubules and the lumen of the epididymides were observed under the light microscope. Fluorescence-conjugated polyclonal antibodies to Fas and Fas ligand (FasL) were used to localize Fas and FasL. TUNEL staining of germ cells and Sertoli cells was performed by the AKPase method. TUNEL-positive rate ( % positive cells) and TUNEL-positive area (area occupied by stained cells) were analysed by KS400 Image Analysis System. The DNA laddering analysis was performed by agarose gels electrophoresis. Results: In those rats infected with UU: (1) Exfoliated germ cells were dramatically increased. Many multinucleated giant cells were found in the seminiferous tubules and the lumen of the epididymides. (2) The number of TUNEL-positive cells and the TUNEL-positive area were significantly increased.(3) The expression of Fas and FasL in germ cells and Sertoli cells was up-regulated. (4) Discrete bands of fragmented DNA were found in the testicular cells. Conclusion: In male rats, germ cell apoptosis was increased in UU infection.

OBJECTIVETo establish the approach to detecting two biovars of Ureaplasma urealyticum (Uu) in human semen and to investigate the relationship between the two biovars of Uu infection and the quality of human semen.
METHODSBased on the 16S-23S rRNA intergenic spacer region, three pairs of primers were designed, the species specific primer and two biovars primers (Parvo primer and T960 primer). The two biovars of Uu were detected in the semen from 949 men by semen culture and PCR assay. Meanwhile, semen routine analyses were performed.
RESULTSIn the 949 subjects, 199 were Uu positive both in Uu liquid culture and PCR assay (199/949, 21.1%), of which 136 (136/199, 68.3%) were Parvo biovar, 54 (54/199, 27.1%) T960 biovar, and 9 (9/199, 4.5%) both Parvo and T960 biovars. Compared with the Parvo and the negative groups, human sperm viability was significantly decreased (P < 0.05 ) in the Uu T960 infection group. The difference of sperm motility and density had no statistic significance.
CONCLUSIONA significant correlation has been found between Uu T960 biovar infection and human sperm viability

The purpose of this study was to establish real-time based methods for detection of NPM1 gene mutation in acute myeloid leukemia (AML). Primers/probes were designed according to the clustered region of NPM1 mutations on exon 12. Two real-time PCR assays, including high resolution melting curve (HRM) and allele-specific PCR (AS-PCR), were developed and clinically evaluated with 89 AML samples, which were parallelly detected by capillary electrophoresis (CE) and sequencing. The results showed that a total of 17 mutation-positive samples were detected, including type A (15 cases), type B (1 case) and type Nm (1 case). HRM assay could detect all mutant types, and the analytical sensitivity was around 5%. In contrast, AS-PCR assay detected only 95% mutant types, but its sensitivity was as high as 0.01%. It is concluded that considering the characteristics of each method as well as the clinical evaluation results, HRM may be used for screening of NPM1 mutations at diagnosis, while the AS-PCR can be used for the MRD quantification during follow-up.

Lie detection technology has been applied increasingly to investigate and solve criminal cases. This article explores the evolvement of lie detection technology in the ancient times and the application of the psychological and physiological parameters which have become more accurate with the introduction of modern polygraph. The cognitive exploration and the application of Event Related Potentials (ERPs), functional Magnetic Resonance Imaging (fMRI), and Event-Related functional Magnetic Resonance Imaging (E-R fMRI) have made detection technology focus on the brain activities, which produce more objective results by tracing the original state of lying. In summary, this article describes different types of lie detections, simple and complex, their working principles, the latest development, and the prospect of their application in forensic science.

Journal of Korean Academy of Nursing 2024;54(4):478-494
Purpose:
This systematic review aimed to scrutinize the progression of symptom cluster research in adult cancer patients who received primary or adjuvant chemotherapy between 2001 and 2023, providing a comprehensive understanding of clinical practice and future research.
Methods:
PubMed, Ovid MEDLINE, Excerpta Medica Database, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, and Web of Science databases were searched for theme words and free words related to symptom clusters, cancer, and chemotherapy. Eligible studies were published between January 1, 2001, and May 30, 2023; adults who were diagnosed with cancer and received primary or adjuvant chemotherapy were evaluated.
Results:
Twenty-eight studies were included in this review. The Memorial Symptom Assessment Scale emerged as the predominant instrument and exploratory factor analysis was the most frequently employed statistical method to identify symptom clusters. Psychological, gastrointestinal, and physical image symptom clusters were the most commonly delineated. Furthermore, the temporal stability of the symptom clusters showed varying dynamics, with psychological symptom clusters displaying relative consistency over time.
Conclusion
Interventions are needed for the most common and stable symptoms in patients with cancer undergoing chemotherapy. Future endeavors may necessitate more longitudinal studies to delve deeper into the temporal stability and dynamic variations of symptom clusters. Such investigations hold promise for advancing symptom cluster research, elucidating the underlying mechanisms, and fostering the development of targeted interventions, thereby enriching the symptom management paradigm in oncological care.
