Nutrient deficiencies on the rise: Vitamin A levels take a nosedive over the last decade, causing the rise of infectious diseases such as measles

(Natural News) Even though developed nations boast of great technology, infrastructure, economy, and advanced medical care, they still suffer from ballooning rates of obesity, chronic disease, cardiovascular issues, metabolic disorders, and cancer. Infectious diseases still run rampant in developed nations, despite advances in plumbing and sanitation. The breakdown of developed nations is a slow and...

AbstractThe activity concentrations of natural radionuclides from the238U and232Th series and singly occurring radionuclide40K have been assessed in most commonly used building materials in Kannur district, Kerala, using well established gamma ray spectrometry employing 5  cm × 5 cm scintillation NaI (Tl) detector. The results of the present work include activities of radionuclides viz.40K,226Ra and232Th and associated radiological parameters. The important and expected significant parameters estimated from the activities were radium equivalent activity (Raeq), hazard indexes and dose paramete...

Castrejon-Sanchez, Guillermo Aguilar, Santiago Camacho-Lopez, Marco Camacho-LopezAbstractPhothermal therapy (PTT) is one of the most promising techniques to treat cancer. Finding the ideal PTT agent nanomaterial has remained a challenge and has brought the interest of several researchers. In this work, we report the synthesis of molybdenum oxide (MoOx) nanoparticles (NPs), which exhibit absorption in the biological optical window ~840 nm, by usi...

Publication date: Available online 17 September 2019Source: Mutation Research/Fundamental and Molecular Mechanisms of MutagenesisAuthor(s): Rebekah J. Hutcherson, Michael G. KempAbstractThe ATR protein kinase is known to protect cells from DNA damage induced during the replicative phase of the cell cycle. Small molecule ATR kinase inhibitors have therefore been developed to improve the effectiveness of DNA damage-based chemotherapy regimens aimed at killing rapidly proliferating tumor cells. However, whether ATR functions in a similar manner in non-replicating cells has not been examined and is important considering the fa...

Publication date: 17 September 2019Source: Cell Reports, Volume 28, Issue 12Author(s): Carlos Zeledon, Xiaojuan Sun, Cédric Plutoni, Gregory EmerySummaryCollective cell migration is involved in various developmental and pathological processes, including the dissemination of various cancer cells. During Drosophila melanogaster oogenesis, a group of cells called border cells migrate collectively toward the oocyte. Herein, we show that members of the Arf family of small GTPases and some of their regulators are required for normal border cell migration. Notably, we found that the ArfGAP Drongo and its GTPase-activating ...

Broekman, Xandra O. BreakefieldSummaryGliomas are primary, diffusely infiltrating brain tumors. Microglia are innate immune cells in the CNS and make up a substantial portion of the tumor mass. Glioma cells shape their microenvironment, communicating with and reprogramming surrounding cells, resulting in enhanced angiogenesis, immune...

Seelig, Siddheshvar Bhela, Brandon J. Burbach, David Masopust, Vaiva VezysSummaryThe immune system adapts to constitutive antigens to preserve self-tolerance, which is a major barrier for anti-tumor immunity. Antigen-specific reversal of tolerance constitutes a major goal to spur therapeutic applications. Here, we show that robust, iterative, systemic stimulation targeting tissue-specific antigens in the context of acute infections reverses establish...

In this study we assessed the diagnostic usefulness of transorbital sonography in IIH with a special focus on color Doppler imaging of the central retinal artery. IIH patients presented papilledema and enlarged ONSD. ONSD accurately predicted an increased intracranial pressure in IIH (cut-off: 5.8 mm, 81% sensitivity, 80% specificity). 24 h following therapeutic lumbar puncture ONSD diminished significantly, whereas papilledema was not changed. PSV (peak systolic velocity) and Vmean (mean flow velocity) of the central retinal artery were increased in IIH patients compared to controls. PSV accurately predicted an increa...

Conclusion: The incidence rate of non-communicable diseases increased over the decade and was associated with increased mortality and disability, reduced quality of life, and increased health-care costs, indicating an urgent need to establish prevention and control programs. The rising trend in the incidence of cancers may also become a health care issue in Saudi Arabia in the coming years. PMID: 30834424 [PubMed - in process]

In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging. Greater Modest Activity in Late Life Correlates with Lower Incidence of Dementia ...
