Sleep is an extremely important physiological state to maintain human life. Sleep disorders can not only cause anxiety and depression, but also induce multi-system diseases that seriously affect brain function and physical health. The neuroinflammation is a key pathological process after sleep disorders, which can induce a series of nervous system diseases.

The hard-shelled mussel () has been used as a traditional Chinese medicine and health food in China for centuries. Polysaccharides from mussel has been reported to have multiple biological functions, however, it remains unclear whether mussel polysaccharide (MP) exerts protective effects in intestinal functions, and the underlying mechanisms of action remain unclear. The aim of this study was to investigate the protective effects and mechanism of MP on intestinal oxidative injury in mice.

This study reports the case of an elderly man with a large tumour of the pelvic cavity and scrotum which was once diagnosed as a prostate cyst. Imaging studies considered the source of the tumour to be prostate, and the tumour was ultimately diagnosed by confirmed tissue expression of prostate specific antigen (PSA) and prostate acid phosphatase (PSAP) after surgery. This is the first report about dumbbell-shaped prostatic cystadenoma with invasive growth and even urethral damage, but there was no evidence of clear malignancy.

  • Apple snails, specifically the Pomacea genus, have spread in southern China since the 1980s, revealing genetic mixing between species P. canaliculata and P. maculata through nuclear EF1α gene sequencing.
  • A study utilized a multiplex PCR method to analyze genetic patterns of 30 apple snail populations, finding a prevalence of hybrids and a mix of genetic traits within egg clutches, suggesting complex breeding behaviors.
  • Results indicate that hybridization may enhance fitness traits in apple snail populations, making them a relevant model for studying the effects of hybridization in ecology.

  • - The study evaluated the effectiveness of metallic stents versus ordinary polymer stents in treating malignant ureteral obstruction (MUO) in 76 patients by comparing operation success rates, duration, patency, serum creatinine levels, postoperative complications, and quality of life (QOL) scores.
  • - Results showed similar success rates for both types of stents, but the metallic stent group had a significantly longer operation time, lower post-procedural complications, and consistently better QOL scores after 6 months and 1 year.
  • - Though there were no significant differences in serum creatinine levels between groups post-operation, the metallic stent patients maintained stable creatinine levels, while patients with polymer stents showed an increase

CAR is a transmembrane protein that is expressed in various epithelial and endothelial cells. CAR mediates adenoviral infection, as well as adenovirus-mediated oncolysis of AxdAdB-3, an E1A/E1B double-restricted oncolytic adenovirus, in prostate cancer cells. This study further assessed the therapeutic efficacy of AxdAdB-3 with Arg-Gly-Asp (RGD)-fiber modification (AxdAdB3-F/RGD), which enables integrin-dependent infection, in prostate cancer.

B7-H4 is a recently identified member of the B7 family considered to negatively regulate the immune response, and has been associated with the occurrence and development of certain types of tumor. However, little is known regarding the importance of human B7-H4 expression in bladder urothelial carcinoma. In the present study, B7-H4 expression in the tissues and sera of patients with bladder urothelial carcinoma was investigated, along with the clinical significance.

Background: Trichoderma brevicompactum is the Trichoderma species producing simple trichothecenes-trichodermin, a potential antifungal antibiotic and a protein synthesis inhibitor. However, the biosynthetic pathway of trichodermin in Trichoderma is not completely clarified. Therefore, transcriptome and gene expression profiling data for this species are needed as an important resource to better understand the mechanism of the trichodermin biosynthesis and provide a blueprint for further study of T.

Bombyx mori nucleopolyhedrovirus (BmNPV) is a baculovirus that selectively infects the domestic silkworm. In this study, six BmNPV strains were compared at the whole genome level. We found that the number of bro genes and the composition of the homologous regions (hrs) are the two primary areas of divergence within these genomes.

Bombyx mori nucleopolyhedrovirus (BmNPV), a member of the Baculoviridae, is a major pathogen of silkworm and has also been recently developed as an expression vector for heterologous gene expression in the silkworm larvae and pupae. To better understand the diversity of this important baculovirus, we sequenced the complete genome of the BmNPV strain isolated from India, where its host is available throughout the year due to its tropical climate. The genome of the Indian strain consists of 127,879 nucleotides, with a G+C content of 40.

A baculovirus, named BomaNPV S2, was isolated from a diseased larva of the wild silkworm, Bombyx mandarina. Notably, BomaNPV S2 exhibited a distinguishing feature in that its host range covered that of both Bombyx mori nucleopolyhedrosis virus (BmNPV) and Autographa californica multiple nucleopolyhedrovirus (AcMNPV) in cultured cells. It could replicate in cells of B.

Although microarray and expressed sequence tag (EST)-based approaches have been used to profile gene expression during baculovirus infection, the response of host genes to baculovirus infection and the interaction between baculovirus and its host remain largely unknown. To determine the host response to Bombyx mori nucleopolyhedrovirus infection and the dynamic interaction between the virus and its host, eight digital gene expression libraries were examined in a Bm5 cell line before infection and at 1.5, 3, 6, 12, 24, 48, and 96 h postinfection.

  • The BomaNPV S1 strain is less virulent than the BmNPV T3 strain in infecting the silkworm, Bombyx mori.
  • The complete genome of BomaNPV S1, which is 126,770 nucleotides long, was sequenced and found to have high similarity to the BmNPV T3 strain, with 133 potential ORFs identified.
  • Differences were noted in specific genes, with BomaNPV S1 lacking the bro-b and bro-e genes and variations observed in repeat units, suggesting that these strains may be variants of each other and highlighting the potential role of genetic differences in baculovirus strain diversity.

Bombyx mori nucleopolyhedrovirus (BmNPV) ORF41 (Bm41), homologous to Ac52, is a gene present in most lepidopteran nucleopolyhedroviruses. Bm41 transcripts and encoded protein in BmNPV-infected cells can be detected from 3 and 6 h post-infection, respectively. Immunoassays have shown that Bm41 is not a viral structural protein and is detected in both the nuclei and cytoplasm of infected cells.

The ORF9 of Bombyx mori nucleopolyhedrovirus (BmNPV) (Bm9) is conserved in all completely sequenced lepidopteran nucleopolyhedroviruses. RT-PCR analysis demonstrated that Bm9 is an early and late transcribed gene that is initiated at 3 h post-infection, and immunofluorescence microscopy showed that Bm9 is localized mainly in the cytoplasm of infected cells. To determine the role of Bm9 during virus infection, Bm9 was knocked out by recombination in a BmNPV genome propagated as a bacmid in Escherichia coli.

A BmNPV Bacmid with the Bmvp80 gene disrupted was constructed using the ET-recombination system in Escherichia coli to investigate the role of Bmvp80 during the baculovirus life cycle. Disruption of Bmvp80 resulted in single cell infection phenotype, whereas a rescue BmBacmid restored budded virus titers to wild type levels; however, the homologous gene Ac104 (Acvp80) from AcMNPV could not complement the BmBacmid lacking a functional Bmvp80 gene. Electron microscopy of cells transfected with BmNPV lacking functional Bmvp80 revealed that the number of nucleocapsids was markedly lower.
