Effects of Different Dietary Approaches on Type 2 Diabetes Mellitus: A Review

Type 2 diabetes (T2D) is a metabolic disorder that occurs due to various etiologies including lifestyle. One of the significant contributors in causing Type-2 diabetes is diet. For high-risk individuals, diet is way more significant in causing Type-2 diabetes. This present study discussed several published papers comprising of various food categories and their effects on type-2 diabetes or its role in causing the disorder. The study revealed the advantages of functional foods and their role in the prevention of T2D. The study has elaborated the outcome of T2D due to consumption of fats, carbohydrates, protein, dietary fibres, red meat, fried food, common beverages like carbonated drinks, and a few other foods. The authors also reviewed T2D from the aspect of religion, region, specific lifestyles, smoking and drinking habit and body weight. Overall, the study has successfully drawn a map of the spectrum of dietary role in T2D including its prevention, increasing the risk of T2D, its causation and affecting the outcome of the disorder.

Nicotinamide activates latent HIV-1 ex vivo in ART suppressed individuals, revealing higher potency than the association of two methyltransferase inhibitors, chaetocin and BIX01294

ABSTRACT Background: Latent HIV-1 is a major hurdle in obtaining HIV-1 sustained virological remission (SVR). Here we explored histone deacetylation inhibition property of nicotinamide (NAM; n = 17) for the first time in comparison to a combination of methyltransferase inhibitors (MTIs; Chaetocin and BIX01294; n = 25) to reactivate latent HIV ex vivo in CD8-depleted PBMCs from antiretroviral treated aviremic individuals. Results: NAM reactivated HIV-1 from 13/17 (76.4%) samples compared to 20/25 (80.0%) using MTIs with mean viral load (VLs) of 4.32 and 3.22 log10 RNA copies/mL, respectively (p = 0.004). Mean purging time after NAM and MTIs stimulation was 5.1 and 6.75 days, respectively (p = 0.73). Viral purging in autologous cultures exhibited blunted HIV recovery with fluctuating VLs followed by a complete viral extinction when expanded in allogenic system. Electron microscopy from five supernatants revealed anomalous viral particles, with lack of complete viral genomes when characterized by ultradeep sequencing through metagenomics approach (n = 4). Conclusion: NAM alone was more potent HIV-1 activator than combination of MTIs, with potential of clinical use.

Comparative bio-efficacy of nuclear polyhedrosis virus (NPV) and Spinosad against American bollwormm, Helicoverpa armigera (Hubner)

ABSTRACT American bollworm (ABW), Helicoverpa armigera (Hubner), is considered as a major pest of cotton, Gossypium hirsutum, all over the globe. Due to its destructive feeding nature and continuous consumption of the same chemicals, it devolved resistant against many insecticides. Therefore, a combined application of bio- and synthetic-pesticide need to evaluate against this pest. The entomopathogenic viruses like nuclear polyhedrosis virus (NPV), a member of baculoviruses, can be the potential candidates for better control against ABW. The present study was conducted to assess the comparative efficacy of NPV and Spinosad 240SC (with the concentration of 250 mL · ha-1) against ABW in the controlled environment. The ABW was treated with different concentrations of NPV and Spinosad separately and in a combination of NPV with 0.1% Spinosad. The results revealed that highest concentrations showed highest mortality (95%) followed by 95%, 92%, 84%, 82% and 78% mortality at 1 × 109, 1 × 108, 1 × 107, 1 × 106 and 1 × 105 POBs, respectively. Spinosad when mixed in diet give 100% mortality at 0.8% followed by 50.87%, 42.10%, 29.82%, 26.31% and 22.80% mortality at 0.4%, 0.2%, 0.1%, 0.5% and 0.025% respectively. The results of this study revealed that microbial control of ABW through NPV is an effective tool. The repeated use of synthetic pesticides caused the resurgence of many insect pests, and this study results would provide useful insight to build a framework for future investigations for the management of many major insect pests.

Exploring Durable Genetic Resistance against Leaf Rust through Phenotypic Characterization and Lr34Linked STS Marker in Wheat Germplasm / Explorando a resistência genética duradoura contra a ferrugem da folha através da caracterização fenotípica e do STS marker relacionado ao (GENE) LR34 do germoplasma do trigo

Present study was aimed to screening the population of 25 wheat genotypes from Baluchistan region of Pakistan along with five commercial cultivars for leaf rust adult plant resistance (APR) through gene postulation using natural inoculation of Puccinia triticina Erikss local pathotype. Infection severity was recorded on scale in comparison with susceptible control "Morroco" cultivar. On the basis of phenotypic score, seven accessions and four varieties (Zardana-89, Sariab-92, Zarlashta-99 and Raskoh-05) with AUDPC values up to 20% were characterized as resistant genotypes. Coefficient of infection (CI) score ranged from 0-10 for some accessions and cultivars showing high level of adult plant resistance. Furthermore, bi-allelic STS marker csLV34 having close linkage with Lr34 (0.4cM). This marker amplified one gene specific allele of 150bp in 21 genotypes, including 19 accessions and two commercial varieties (Sariab-92 and Zarghoon-79) which confirmed presence of Lr34 gene conferring adult plant resistance against leaf rust. The rust pathogenicity scale varied for accessions from resistant to moderately susceptible. However, beside Lr34, phenotypic gene postulation, in combination with marker assisted selection for leaf rust resistance, has revealed presence of some other unknown resistance genes in local wheat germplasm which signified its use in wheat improvement programs both locally and abroad.

O presente estudo teve como objetivo a triagem da população de 25 genótipos de trigo do Baluchistão, região do Paquistão, juntamente com cinco cultivares comerciais para o estudo da resistência à ferrugem da folha em plantas adultas (leaf rust adult plant resistance, APR, em inglês) através da postulação gênica usando a inoculação natural do patótipo local da Puccinia triticina Erikks. A gravidade da infecção foi registrada na escala em comparação ao cultivar de controle suscetível "Morroco". Com base na pontuação fenotípica, sete acessões e quatro variedades (Zardana-89, Sariab-92, Zarlashta-99 and Raskoh-05) com valores de AUDPC (area under the disease progress curve, em inglês) até 20% foram caracterizados como genótipos resistentes. A pontuação do coeficiente de infecção (CI) variou no intervalo de 0-10 para algumas acessões e cultivares evidenciando uma elevada resistência nas plantas adultas. Além disso, o STS marker para o csLV34 bi-alélico demonstrou uma ligação estreita com o Lr34 (0.4cM). Este marcador amplificou um alelo específico do gene do 150bp em 21 genótipos, incluindo 19 acessões e duas variedades comerciais (Sariab-92 and Zarghoon-79) o que confirmou a presença do gene Lr34 conferindo resistência às plantas adultas contra a ferrugem da folha. A escala de patogenicidade da ferrugem para as acessões de resistente a moderadamente suscetível. Contudo, além do Lr34, a postulação gênica fenotípica, em combinação com a seleção auxiliada (ou assistida) por marcadores para a resistência da ferrugem da folha, revelou a presença de outros genes resistentes desconhecidos no germoplasma do trigo local o que justifica a sua utilização em programas de melhoramento do trigo tanto a nível local quanto a nível internacional.

Acute kidney injury following coronary artery bypass graft surgery in a tertiary public hospital in Malaysia: an analysis of 1228 consecutive cases

Background: Acute kidney injury (AKI) following cardiac surgery is well established but the reported incidence is variable due to varying definitions and criteria. Furthermore there is a paucity of such data from Southeast Asia. Objectives: To determine the incidence of AKI, the associated risk factors, and its impact on early mortality and intensive care unit/hospital stay. Method: This is a single centre retrospective observational study to evaluate outcomes on 1260 consecutive patients from a multi-ethnic Southeast Asian population who underwent a primary isolated coronary artery bypass graft (CABG) operation. Data was collected from the hospital’s electronic database and analysed using basic descriptive statistics and logistic regression. Results: Overall incidence was 36.2% including 5.5% of patients who required renal replacement therapy (RRT). Multivariate analysis identified age, insulin-dependent diabetes mellitus (IDDM), baseline serum creatinine level (SCr), recent myocardial infarction (MI), cardiopulmonary bypass (CPB) time and intra-aortic balloon pump (IABP) use as independent risk factors for AKI. For patients who required RRT, the SCr and IDDM remained independent predictors. Early 30-day mortality (11.5% vs 0.9%) was significantly higher in patients who developed AKI following CABG. Similarly, AKI was associated with a slight but statistically significant increase in intensive care unit (ICU) and hospital stay. Conclusion: Better prognostication and preventative strategies are required to better risk stratify patients undergoing CABG and optimise utilisation of limited healthcare resources.

High prevalence and incidence of HIV-1 in a counseling and testing center in the city of Itajaí, Brazil

ABSTRACT Itajaí is a port city in southern Brazil with one of the highest incidence and mortality rates from AIDS in the country. The prevalence and incidence of HIV infection were investigated in 1085 of 3196 new HIV-1 infection cases evaluated in the counseling and testing center of Itajaí from January 2002 to August 2008. Recent infections were assessed using the BED(tm), and polregion sequencing was performed in 76 samples. The prevalence ranged from 3.08% to 6.17% among women and from 10.26% to 17.36% among men. A total of 17% of infections were classified as recent, with annual incidence varying from 1.6% to 4.8 per 100 patient/year among women and from 2.05% to 8.5 per 100 patient/year among men. Pol sequences were obtained from 38 randomly recent infections selected individuals: 71% were infected by subtype C, 24% B, 2% D, and 2% F1. Among 38 subjects with established infection, 76% were subtype C, and 24% B. Transmitted drug resistance was detected in 18.4% of recent infection subjects (7.8% to nucleoside analog reverse-transcriptase inhibitors, 5.2% to non-nucleoside reverse-transcriptase inhibitors, and 5.2% protease inhibitors) and 5.2% of subjects with established infection had nucleoside analog reverse-transcriptase inhibitors resistance. The high prevalence and incidence of HIV infection in this region is unprecedented in studies involving cases evaluated in the counseling and testing centers in Brazil.
