Culturally tailored lifestyle interventions for the prevention and management of type 2 diabetes in adults of Black African ancestry: a systematic review of tailoring methods and their effectiveness
Objective:
To evaluate the cultural tailoring methods used in type 2 diabetes (T2D) prevention and management interventions for populations of Black African ancestry, and to examine their effectiveness on measures of glycaemia. /
Design:
Three databases were searched in October 2020; eligible studies used a randomized controlled trial (RCT) design to evaluate the effectiveness of culturally tailored lifestyle interventions compared to usual care for the prevention or management of T2D in adults of Black African ancestry. Cultural tailoring methods were evaluated using the Facilitator-Location-Language-Messaging (FiLLM) framework, whereby facilitator, refers to delivery by individuals from the target community, language focuses on using native language or language appropriate to literacy levels, location refers to delivery in meaningful settings, and messaging is tailoring with relevant content and modes of delivery. /
Results:
Sixteen RCTs were identified, all from USA. The mean age of participants was 55 years, majority female. Six of 15 RCTs reported significant improvements in glycated haemoglobin (HbA1c) at 6- and 8-months; one, in prediabetes, reported significantly improved fasting plasma glucose. Diabetes knowledge improvement (5/7 studies) was associated with HbA1c improvement. The majority tailored to location (12/16), facilitators (11/16), messaging (9/16) and language (6/16) domains of FiLLM. Those with ethnically matched facilitators and those which tailored to more than one domain showed the greatest HbA1C benefits. /
Conclusion:
This evidence supports the effectiveness of culturally tailored lifestyle interventions for T2D management in populations of Black African ancestry, with further RCTs needed to evaluate interventions for T2D prevention and for communities outside of the USA
Isolation and antimicrobial activity of rutin and its derivatives from Ruta chalepensis (Rutaceae) growing in Iraq
Rutin (1), rutin 3'-methyl ether (2), and a new flavonol glycoside, 6-hydroxy-rutin 3',7-dimethyl ether (3), were isolated from the methanol extract of the fruits of Ruta chalepensis, collected from Diyala, Iraq. Their structures were elucidated by spectroscopic analyses, including 1D-, 2D-NMR and HRESIMS. Antimicrobial activity of compounds 1-3 was tested against four Gram +ve and Gram –ve bacterial strains, and the only fungal strain, Candida albicans, using the 96-well based resazurin microtitre assay
Causes of delays in budget absorption as the development of good governance on deconcentration and co-administration task budget (A case study at the work unit of DKP-NTB Province)
The objective of study is to determine the causes of delays in the absorption of De-concentration (Decon) and Co-administration Task (TP) budget at the level of Work Unit. In carrying out its function as an agent of the Ministry of Maritime Affairs and Fisheries (DKP). The Work Unit has developed operational plan, nevertheless it plan could not be followed up. Such condition surely has consequences on the budget absorption at the Work Unit. This study is a qualitative study using a case study approach. The study uses a holis-tic single case study. The results indicate that there are many obstacles encountered by the Work Unit in carrying out its daily activities related to budget absorption. The obstacles may be from internal factors and external factors. The strong intervention of principal in Decon and TP budget is a key issue of the external factor that makes the Work Unit unable to be consistent to the operational plan drawn up. Besides, the procurement of goods and services through the Procurement Services Unit is also an obstacle for the Work Unit in executing the work using tender mechanism. Other external factors are the mechanisms of Money Supply (UP) and the Change of Money Supply (GUP) that cause the Work Unit to get difficulty in setting up funds for activities. Meanwhile, the internal factors that con-strain the Work Unit are issues concerning Human Resources, Standard Operating Proce-dures and Performance Evaluation that have not been implemented well in the internal Work Unit. The theoretical implication of the study is the dominant intervention of the principal (central government) to the agent (Work Unit) is a resistance to the implementa-tion of the values of effectiveness and efficiency in the concept of good governance
Why honey is effective as a medicine. 1. Its use in modern medicine
Honey has been used as a medicine for thousands of years and its curative properties are well documented. However, modern medicine turned its back on honey and it is only now, with the advent of multi-resistant bacteria, that the antibiotic properties of honey are being rediscovered

Quantum dynamics in strong fluctuating fields
A large number of multifaceted quantum transport processes in molecular
systems and physical nanosystems can be treated in terms of quantum relaxation
processes which couple to one or several fluctuating environments. A thermal
equilibrium environment can conveniently be modelled by a thermal bath of
harmonic oscillators. An archetype situation provides a two-state dissipative
quantum dynamics, commonly known under the label of a spin-boson dynamics. An
interesting and nontrivial physical situation emerges, however, when the
quantum dynamics evolves far away from thermal equilibrium. This occurs, for
example, when a charge transferring medium possesses nonequilibrium degrees of
freedom, or when a strong time-dependent control field is applied externally.
Accordingly, certain parameters of underlying quantum subsystem acquire
stochastic character. Herein, we review the general theoretical framework which
is based on the method of projector operators, yielding the quantum master
equations for systems that are exposed to strong external fields. This allows
one to investigate on a common basis the influence of nonequilibrium
fluctuations and periodic electrical fields on quantum transport processes.
Most importantly, such strong fluctuating fields induce a whole variety of
nonlinear and nonequilibrium phenomena. A characteristic feature of such
dynamics is the absence of thermal (quantum) detailed balance.Comment: review article, Advances in Physics (2005), in pres
Proteomic identification and characterization of hepatic glyoxalase 1 dysregulation in non-alcoholic fatty liver disease
Background: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide. However, its
molecular pathogenesis is incompletely characterized and clinical biomarkers remain scarce. The aims of these
experiments were to identify and characterize liver protein alterations in an animal model of early, diet-related,
liver injury and to assess novel candidate biomarkers in NAFLD patients.
Methods: Liver membrane and cytosolic protein fractions from high fat fed apolipoprotein E knockout (ApoE−/−)
animals were analyzed by quantitative proteomics, utilizing isobaric tags for relative and absolute quantitation
(iTRAQ) combined with nano-liquid chromatography and tandem mass spectrometry (nLC-MS/MS). Differential
protein expression was confirmed independently by immunoblotting and immunohistochemistry in both murine
tissue and biopsies from paediatric NAFLD patients. Candidate biomarkers were analyzed by enzyme-linked
immunosorbent assay in serum from adult NAFLD patients.
Results: Through proteomic profiling, we identified decreased expression of hepatic glyoxalase 1 (GLO1) in a
murine model. GLO1 protein expression was also found altered in tissue biopsies from paediatric NAFLD patients. In
vitro experiments demonstrated that, in response to lipid loading in hepatocytes, GLO1 is first hyperacetylated then
ubiquitinated and degraded, leading to an increase in reactive methylglyoxal. In a cohort of 59 biopsy-confirmed adult
NAFLD patients, increased serum levels of the primary methylglyoxal-derived advanced glycation endproduct,
hydroimidazolone (MG-H1) were significantly correlated with body mass index (r = 0.520, p < 0.0001).
Conclusion: Collectively these results demonstrate the dysregulation of GLO1 in NAFLD and implicate the
acetylation-ubquitination degradation pathway as the functional mechanism. Further investigation of the role
of GLO1 in the molecular pathogenesis of NAFLD is warranted.

Pan-cancer analysis of whole genomes
Cancer is driven by genetic change, and the advent of massively parallel sequencing has enabled systematic documentation of this variation at the whole-genome scale(1-3). Here we report the integrative analysis of 2,658 whole-cancer genomes and their matching normal tissues across 38 tumour types from the Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium of the International Cancer Genome Consortium (ICGC) and The Cancer Genome Atlas (TCGA). We describe the generation of the PCAWG resource, facilitated by international data sharing using compute clouds. On average, cancer genomes contained 4-5 driver mutations when combining coding and non-coding genomic elements; however, in around 5% of cases no drivers were identified, suggesting that cancer driver discovery is not yet complete. Chromothripsis, in which many clustered structural variants arise in a single catastrophic event, is frequently an early event in tumour evolution; in acral melanoma, for example, these events precede most somatic point mutations and affect several cancer-associated genes simultaneously. Cancers with abnormal telomere maintenance often originate from tissues with low replicative activity and show several mechanisms of preventing telomere attrition to critical levels. Common and rare germline variants affect patterns of somatic mutation, including point mutations, structural variants and somatic retrotransposition. A collection of papers from the PCAWG Consortium describes non-coding mutations that drive cancer beyond those in the TERT promoter(4); identifies new signatures of mutational processes that cause base substitutions, small insertions and deletions and structural variation(5,6); analyses timings and patterns of tumour evolution(7); describes the diverse transcriptional consequences of somatic mutation on splicing, expression levels, fusion genes and promoter activity(8,9); and evaluates a range of more-specialized features of cancer genomes(8,10-18).Peer reviewe
Genetic programming of macrophages generates an in vitro model for the human erythroid island niche
In vitro differentiation of red blood cells (RBCs) is a desirable therapy for various disorders. Here the authors develop a culture system using stem cell-derived macrophages to show that inducible expression of a transcription factor, KLF1, enhances RBC production, potentially through the induction of three soluble factors, ANGPTL7, IL33 and SERPINB2
