Beneficial effects of a soy-based dietary supplement on lipid levels and cardiovascular risk markers in type 2 diabetic subjects
WSTĘP. Jak ostatnio wykazano, spożycie białek soi poprawia profil lipidowy krwi u osób bez cukrzycy. Celem niniejszego badania było sprawdzenie, czy dodanie do diety białek soi, izoflawonów i włókien liścienia sojowego (preparat Abalon) zmniejsza ryzyko chorób układu krążenia, stężenie cukru i insuliny we krwi u chorych na cukrzycę typu 2.
MATERIAŁ I METODY. W badaniu o charakterze krzyżowym uczestniczyło 20 chorych na cukrzycę typu 2, których przydzielono losowo metodą podwójnie ślepej próby do 6-tygodniowej suplementacji preparatem Abalon [białko soi (50 g/d.) z wysoką zawartością izoflawonów (minimum 165 mg/d.) i włókien liścienia sojowego (20 g/d.)] lub placebo [kazeina (50 g/d.) i celuloza (20 g/d.)], rozdzielonych 3-tygodniowym okresem przerwy.
WYNIKI. Wyniki przedstawiono jako średnie ± SD. Odsetek średniej różnicy wyniku leczenia Abalonem
i placebo wykazał znamiennie niższe wartości średnie po leczeniu Abalonem dla stężenia cholesterolu frakcji LDL (10 ± 15%; p < 0,05), wskaźnika LDL/HDL (12 ± 18%; p < 0,05), apolipoproteiny (apo) B100 (30 ± 38%; p < 0,01), triglicerydów (22 ± 10%; p <INTRODUCTION. Consumption of soy protein has recently
been shown to improve the blood lipid levels
in nondiabetic subjects. The purpose of this study
was to evaluate if a dietary supplement of soy protein,
isoflavones, and cotyledon fiber (Abalon) affects
cardiovascular risk markers, blood glucose, and
insulin levels in type 2 diabetic subjects.
MATERIAL AND METHODS. Twenty type 2 diabetic
subjects participated in a crossover trial. They were
randomized to double-blind supplementation for
6 weeks with Abalon (soy protein [50 g/day] with
high levels of isoflavones [minimum 165 mg/day]
and cotyledon fiber [20 g/day]) or placebo (casein
[50 g/day] and cellulose [20 g/day]), separated by
a 3-week wash-out period.
RESULTS. The results are expressed as means ± SD.
The percentage mean treatment difference between
Abalon and placebo demonstrated significantly
lower mean values after Abalon for LDL cholesterol
(10 ± 15%; P < 0.05), LDL/HDL ratio (12 ± 18%; P
The Norwegian childhood cancer biobank
Background - The rapidly expanding era of “omics” research is highly dependent on the availability of quality-proven biological material, especially for rare conditions such as pediatric malignancies. Professional biobanks provide such material, focusing on standardized collection and handling procedures, distinctive quality measurements, traceability of storage conditions, and accessibility. For pediatric malignancies, traditional tumor biobanking is challenging due to the rareness and limited amount of tissue and blood samples. The higher molecular heterogeneity, lower mutation rates, and unique genomic landscapes, however, renders biobanking of this tissue even more crucial.
Aim - The aim of this study was to test and establish methods for a prospective and centralized biobank for infants, children, and adolescents up to 18 years of age diagnosed with cancer in Norway.
Methods - Obtain judicial and ethical approvals and administration through a consortium, steering committee, and advisory board. Develop pipelines including SOPs for all aspects in the biobank process, including collection, processing and storing of samples and data, as well of quality controlling, safeguarding, distributing, and transport.
Results - The childhood cancer biobanking started at Oslo University Hospital in March 2017 and was from 2019 run as a national Norwegian Childhood Cancer Biobank. Informed consent and biological samples are collected regionally and stored centrally. Approximately 12 000 samples from 510 patients and have been included by January 1, 2021, representing a 96% consent and participation rate among our newly diagnosed patients.
Conclusion - A well-functioning nationwide collection and centralized biobank with standardized procedures and national storage for pediatric malignancies has been established with a high acceptance among families
HldE Is Important for Virulence Phenotypes in Enterotoxigenic <i>Escherichia coli</i>
Enterotoxigenic Escherichia coli (ETEC) is one of the most common causes of diarrheal illness in third world countries and it especially affects children and travelers visiting these regions. ETEC causes disease by adhering tightly to the epithelial cells in a concerted effort by adhesins, flagella, and other virulence-factors. When attached ETEC secretes toxins targeting the small intestine host-cells, which ultimately leads to osmotic diarrhea. HldE is a bifunctional protein that catalyzes the nucleotide-activated heptose precursors used in the biosynthesis of lipopolysaccharide (LPS) and in post-translational protein glycosylation. Both mechanisms have been linked to ETEC virulence: Lipopolysaccharide (LPS) is a major component of the bacterial outer membrane and is needed for transport of heat-labile toxins to the host cells, and ETEC glycoproteins have been shown to play an important role for bacterial adhesion to host epithelia. Here, we report that HldE plays an important role for ETEC virulence. Deletion of hldE resulted in markedly reduced binding to the human intestinal cells due to reduced expression of colonization factor CFA/I on the bacterial surface. Deletion of hldE also affected ETEC motility in a flagella-dependent fashion. Expression of both colonization factors and flagella was inhibited at the level of transcription. In addition, the hldE mutant displayed altered growth, increased biofilm formation and clumping in minimal growth medium. Investigation of an orthogonal LPS-deficient mutant combined with mass spectrometric analysis of protein glycosylation indicated that HldE exerts its role on ETEC virulence both through protein glycosylation and correct LPS configuration. These results place HldE as an attractive target for the development of future antimicrobial therapeutics
Geographical and ecological analyses of multiple myeloma in Denmark:Identification of potential hotspot areas and impact of urbanisation
BACKGROUND: The aetiology of multiple myeloma (MM) is unknown but various environmental exposures are suspected as risk factors. We present the first paper analysing the geographical distribution of MM in Denmark at the municipal level to investigate variations that could be explained by environmental exposures.METHODS: Patients diagnosed with MM in Denmark during 2005-2020 were identified from nationwide registries and grouped into the 98 Danish municipalities based on residence. The age- and sex-standardised incidence rate (SIR) of each municipality was compared to the national incidence in a funnel plot with 95% control limits. Differences in SIRs of rural, suburban, and urban areas were evaluated with incidence rate ratios.RESULTS: In total, 5243 MM patients were included. Overall, we found a heterogeneous geographical distribution of MM and a potential hotspot in southern Denmark. This hotspot contains three municipalities with SIRs above the 95% control limit assuming considerably higher rate of MM compared to the national incidence rate. A significant higher SIR was found in rural areas compared to urban areas.CONCLUSION: The geographical distribution of MM in Denmark indicates that the risk of developing MM depends on place of residence probably due to environmental factors.</p
Impaired NDRG1 functions in Schwann cells cause demyelinating neuropathy in a dog model of Charcot-Marie-Tooth type 4D
Mutations in the N-myc downstream-regulated gene 1 (NDRG1) cause degenerative polyneuropathy in ways that are poorly understood. We have investigated Alaskan Malamute dogs with neuropathy caused by a missense mutation in NDRG1. In affected animals, nerve levels of NDRG1 protein were reduced by more than 70% (p < 0.03). Nerve fibers were thinly myelinated, loss of large myelinated fibers was pronounced and teased fiber preparations showed both demyelination and remyelination. Inclusions of filamentous material containing actin were present in adaxonal Schwann cell cytoplasm and Schmidt-Lanterman clefts. This condition strongly resembles the human Charcot-MarieTooth type 4D. However, the focally folded myelin with adaxonal infoldings segregating the axon found in this study are ultrastructural changes not described in the human disease. Furthermore, lipidomic analysis revealed a profound loss of peripheral nerve lipids. Our data suggest that the low levels of mutant NDRG1 is insufficient to support Schwann cells in maintaining myelin homeostasis. (C) 2020 The Author(s). Published by Elsevier B.V.
