Mantle cell lymphoma (MCL) is an uncommon subtype of mature B-cell non-Hodgkin lymphoma characterized by specific morphologic, immunophenotypic, and genetic characteristics, namely the t(11;14)(q13;q32) chromosomal translocation with resultant cyclin D1 overexpression. MCL has a generally aggressive course and is often widely disseminated at the time of diagnosis. Skin involvement is exceedingly rare and is seldom the first manifestation of MCL. We present a case of MCL in an 84-year-old man with cutaneous involvement as the first manifestation, discovered incidentally after biopsy of a persistent nodule believed to be an insect bite. This case not only serves to raise awareness of the possibility of MCL presenting in the skin but also to point out that MCL can have lesions with both an insect-bite-like reaction and a deeper dermal MCL infiltrate.Fruit softening is an inevitable event during ripening of red raspberry fruit even when stored at low temperature. In this research, the effects of CaCl2 treatment on softening of red raspberry during storage at 4°C were studied. The results indicated that CaCl2 treatment effectively delayed the decrease of firmness and reduced the respiration rate of red raspberry fruit during storage. The CaCl2 -treated fruit maintained higher protopectin content and lower soluble pectin content compared with controls. The cellulose and starch contents in the fruit treated with CaCl2 kept higher than in the control during storage. Moreover, CaCl2 treatment decreased activities of polygalacturonase (PG), pectin methylesterase (PME), and cellulase (Cx) mainly at the early stage of softening. Application of CaCl2 lead to the decreased activities of amylase (AM) and β-galactosidase (β-gal) compared with controls during the entire storage periods. These results indicated that CaCl2 treatment might delay postharvest softening of red raspberry fruit stored at low-temperature by retarding cell wall degradation and starch hydrolysis. PRACTICAL APPLICATIONS Red raspberry fruit is very popular with consumers because of its high-nutritional value and anticancer effects. However, it has a very short postharvest life and softens easily even when stored at low temperature, which limits its distribution to distant market. Our data indicated that CaCl2 treatment delayed postharvest softening of red raspberry fruit stored at low temperature. The results could provide preliminary yet essential information to research community to further study the molecular mechanisms of softening in red raspberry fruit, and also provide reference data for maintaining quality of postharvest red raspberry fruit.
We hypothesized that autophagy-related genes will be differentially expressed in periodontitis, suggesting an impaired gingival autophagic response associated with disease.
Autophagy is a cellular physiologic mechanism to maintain tissue homeostasis, while deficient autophagic responses increase inflammation and susceptibility to infection.
Rhesus monkeys [<3years to 23years of age (n=34)] were examined for periodontal health and naturally occurring periodontitis. Gingival tissues samples were obtained from healthy or diseased sites, total RNA was isolated, and the Rhesus Gene Chip 1.0 ST (Affymetrix) was used for gene expression analysis of 150 autophagy-related genes.
Comparison of expression levels with adult healthy tissues demonstrated a rather limited number of individual genes that were significantly different across the age-groups. In contrast, with periodontitis in the adults and aged animals, about 15% of the genes were significantly increased or decreased. The differences were reflected 15% of the genes were significantly increased or decreased. The differences were reflected in the mTOR complex (5/12), ULK1/ATG1 complex (5/9), PI3K complex (5/21), ATG9 complex (2/7), ATG12 conjugation/LC3 lipidation (7/22), and lysosome fusion/vesicle degradation [LF/VD (5/10)] activities within the broader autophagic pathway. The genes most greatly altered in gingival tissues of naturally occurring periodontitis were identified in the ATG12 and LF/VD pathways that approximated 50% of the genes in each of those categories. While healthy gingival aging did not appear to reflect altered autophagy gene expression, substantial differences were noted with periodontitis irrespective of the age of the animals. Future studies into the role of autophagy in periodontitis and could offer potential new therapeutic strategies to prevent and/or treat periodontal disease.Pectinatella magnifica is an invasive freshwater bryozoan that has expanded in many localities worldwide, including fishing areas. It contains microbial communities, predominantly consisting of Aeromonas bacteria that are frequently associated with fish infections. The objective of this study was to investigate the potential pathogenicity of Aeromonas spp. associated with P. magnifica and evaluate the health risks for fish. Aeromonas strains were isolated from P. magnifica (101 strains) and from surrounding water (29 strains) in the South Bohemian region and investigated for the presence of 14 virulence-associated genes using PCR. Cilofexor We demonstrated high prevalence of phospholipase GCAT, polar flagellin, enolase, DNAse, aerolysin/cytotoxic enterotoxin, serine protease and heat-stable cytotonic enterotoxin-coding genes. Further, all twelve isolates that were analysed for cytotoxicity against intestinal epithelial cells were found to be cytotoxic. Six of the isolates were also tested as co-cultures composed of pairs. Enhanced cytotoxicity was observed when the pair was composed of strains from different species. In conclusion, P. magnifica is colonized by Aeromonas strains that have a relatively high prevalence of virulence-associated genes and the ability to provoke disease. Results also suggest a possibly increased risk arising from mixed infections.
The syndromes of myocardial infarction/myocardial ischemia with No Obstructive Coronary Artery Disease (MINOCA/INOCA) are seen more and more often. Endothelial dysfunction (ED) leading to ischemic events has been reported in many of these patients. We aimed to compare patients with MINOCA and INOCA regarding brachial artery flow-mediated endothelium-dependent vasodilation (flow-mediated dilation [FMD]) and plasma concentration of cardiotrophin-1 (CT-1).
We included 42 patients with MINOCA and 38 patients with INOCA. Endothelial function was assessed by measuring FMD% and nitroglycerin-mediated dilatation (NMD%) in the brachial artery. The plasma level of CT-1 was determined by solid-phase enzyme-linked immunosorbent assay.
FMD% was significantly lower in MINOCA than in INOCA patients (6.45 ± 2.65 vs 8.94 ± 3.32, P < .001), without significant difference in NMD% (10.69 ± 3.19 vs 12.16 ± 3.69, P = .06). Plasma CT-1 levels were not significantly different 40.1 pg/mL (22.5-102.1) vs 37.2 pg/mL (23.5-67.2), P = .
