In particular, the film is one-molecule-thick and homogenous under low lateral pressure. Upon compression, it transforms into a multilayer structure with inhomogeneities in the form of polar-nonpolar lipid assemblies. selleckchem Based on this model, we hypothesize that TFLL in vivo has a duplex polar-nonpolar structure and it contains numerous mixed lipid aggregates formed because of film restructuring. These findings, despite the simplified character of the model, seem relevant for TFLL physiology as well as for understanding pathological conditions related to the lipids of the tear film. V.p63 is expressed from two promoters and produces two N-terminal isoforms, TAp63 and ΔNp63. Alternative splicing creates three C-terminal isoforms p63α/β/δ whereas alternative polyadenylation in coding sequence (CDS-APA) creates two more C-terminal isoforms p63γ/ε. While several transcription factors have been identified to differentially regulate the N-terminal p63 isoforms, it is unclear how the C-terminal p63 isoforms are regulated. Thus, we determined whether PABPN1, a key regulator of APA, may differentially regulate the C-terminal p63 isoforms. We found that PABPN1 deficiency increases p63γ mRNA through CDS-APA. We also found that PABPN1 is necessary for p63α translation by modulating the binding of translation initiation factors (eIF4E and eIF4G) to p63α mRNA. Moreover, we found that the p53 family, especially p63α, regulates PABPN1 transcription, suggesting that the mutual regulation between p63 and PABPN1 forms a feedback loop. Furthermore, we demonstrated that PABPN1 deficiency inhibits cell growth, which can be rescued by ectopic ΔNp63α. Finally, we showed that PABPN1 controls the terminal differentiation of HaCaT keratinocytes by modulating ΔNp63α expression. Taken together, our findings suggest that PABPN1 is a key regulator of the C-terminal p63 isoforms through CDS-APA and mRNA translation and that the p63-PABPN1 loop modulates p63 activity and the APA landscape. Although deep learning algorithms have shown expert-level performance, previous efforts were mostly binary classifications of limited disorders. We trained an algorithm with 220,680 images of 174 disorders and validated using Edinburgh (1,300 images; 10 disorders) and SNU dataset (2,201 images; 134 disorders). The algorithm could accurately predict malignancy, suggest primary treatment options, render multi-class classification among 134 disorders and improve the performance of medical professionals. The AUCs for malignancy detection were 0.928±0.002 (Edinburgh) and 0.937±0.004 (SNU). The AUCs of primary treatment suggestion (SNU) were 0.828±0.012, 0.885±0.006, 0.885±0.006 and 0.918±0.006 for steroids, antibiotics, antivirals and antifungals. For multi-class classification, the mean Top-1/Top-5 accuracies were 56.7±1.6%/92.0±1.1% (Edinburgh) and 44.8±1.2%/78.1±0.3% (SNU). With the assistance of our algorithm, the sensitivity and specificity of 47 clinicians (21 dermatologists and 26 dermatology residents) for malignancy prediction (SNU; 240 images) improved by 12.1% (p less then 0.0001) and 1.1% (p less then 0.0001), respectively. The malignancy prediction sensitivity of 23 general public significantly increased by 83.8% (p less then 0.0001). The Top-1 and 3 accuracy of 4 doctors in the multi-class classification of 134 diseases (SNU; 2,201 images) increased by 7.0% (p=0.045) and 10.1% (p=0.0020), respectively. The results suggest that our algorithm may serve as an Augmented Intelligence that can empower medical professionals in diagnostic dermatology. Rabies is one of the most dreadful diseases and a major viral zoonosis which has been shown to cause an almost 100% fatality rate in infected victims. It is characterized by acute progressive encephalitis in mammals. This study determined the genotypic characteristics of rabies virus in dogs slaughtered for human consumption based on sequence of a fragment of nucleoprotein gene. Brain tissues were collected from 50 dogs slaughtered in Billiri and Kaltungo Local Government Areas of Gombe State, Nigeria. Direct fluorescent antibody test (DFAT) was used to screen for the presence of rabies virus antigen. Viral RNA isolated from DFAT positive brain tissues were subjected to the reverse transcription polymerase chain reaction (RT-PCR) followed by sequencing of the amplicons. Maximum Likelihood (ML) was used to construct a phylogenetic tree for sequences obtained with 1000 bootstrap replicates. The DFAT detected rabies antigen in 3 (6%) of the 50 dog brain tissues, from which 1 (2%) was positive by RT-PCR. ML phylogeny approach of the nucleotide sequences inferred members as originating lyssavirus genus and dog species. Essentially, MK234794 in this study displayed 99.3% sequence similarity with other related rabies viruses in the Africa 2 cluster (Nigeria, Cameroon, Chad and Niger). Interestingly, MK234794 showed no cluster relation with the Africa 1a, 1b, 3 and Africa 4 clades, respectively. This indicates there is in-country and trans-boundary circulation of the rabies viruses with no co-circulation between the Africa lineages, especially as dogs are continuously being traded due to consumption of dog meat in West Africa. This finding has given additional insight into the molecular epidemiology of rabies virus in Nigeria, therefore providing more baseline information for future design of rabies control programs in the country. Mastitis is the inflammation of mammary glands which causes huge economic loss in dairy cows. Inflammation, any tissue injury and pathogens in cow udder activate Toll-like Receptors (TLRs). Staphylococcus aureus (S. aureus) is the major cause of mastitis. In mastitis, activated TLRs initiate the NF-κB/MAPKs pathways which further trigger the gene expression associated with mastitis followed by innate immune response. In this study, pathogenic-induced gene expression profile of pro-inflammatory cytokines in mammary gland tissues, was investigated in mastitis. The Hematoxylin and Eosin (H & E) results indicated severe histopathological changes in infected tissues. Western blot results suggested the over expressions of TLR2/TLR4 with NF-κB/MAPKs pathways activation in infected tissues. qRT-PCR results revealed the gene expression associated with TLR2/TLR4-mediated NF-κB/MAPKs pathways in infected tissues in comparison with non-infected. Statistical analysis of mRNA and relative protein expression levels indicated the up-regulation of pro-inflammatory cytokines (TNF-α, IL-1β and IL-6) in infected tissues rather than non-infected tissues.
