Dietary restriction (DR) refers to a reduction in food intake to induce undernutrition but not malnutrition, which extends the lifespan of multiple species. Although there are invertebrate aging models, such as the Caenorhabditis elegans and Drosophila melanogaster, aging studies in Lepidoptera are few in number and the underlying life-extending molecular mechanisms are not clear. Research on a broader range of animals is necessary to support generalizations on mechanisms of aging and rates of aging. The aim of this study was to further investigate genes and pathways associated with DR in Bombyx mori...

Arundo donax has been identified as an important biomass and biofuel crop. Yet, there has been little research on photosynthetic and metabolic traits, which sustain the high productivity of A. donax under drought conditions. This study determined phenotypic differences between two A. donax ecotypes coming from stands with contrasting adaptation to dry climate. We hypothesized that the Bulgarian (BG) ecotype, adapted to drier conditions, exhibits greater drought tolerance than the Italian (IT) ecotype, adapted to a more mesic environment...

The human TM6SF2 gene has been implicated in plasma lipoprotein metabolism, alcoholic and non-alcoholic fatty liver disease and myocardial infarction in multiple genome-wide association studies. To investigate the role of Tm6sf2 in metabolic homeostasis, we generated mice with elevated expression using adeno-associated virus (AAV)-mediated gene delivery. Hepatic overexpression of mouse Tm6sf2 resulted in phenotypes previously observed in Tm6sf2-deficient mice including reduced plasma lipid levels, diminished hepatic TG secretion and increased hepatosteatosis...

Bone infection and nonunion are the main orthopedic and traumatic complications whose treatment remains a challenge because multiple factors are involved in the rate of failures when you try to correct them. Knowing these factors were the problem that caused the research through a prospective longitudinal study of 83 patients of 43.3 ± 16.1 years old. They were treated for aseptic and septic nonunion, osteomyelitis, osteitis, malunion or infected joint replacement. The cases were classified with or without postoperative complications and outcome related to systemic and local factors taken prognostic model Cierny-Mader as factors affecting immune surveillance, metabolism and local vascularization...

A wide search for ischemic preconditioning (IPC) mechanisms of cardioprotection identified the light elicited circadian rhythm protein Period 2 (Per2) to be cardioprotective. Studies on cardiac metabolism found a key role for light elicited Per2 in mediating metabolic dependence on carbohydrate metabolism. To profile Per2 mediated pathways following IPC of the mouse heart, we performed a genome array and identified 352 abundantly expressed and well-characterized Per2 dependent micro RNAs. One prominent result of our in silico analysis for cardiac Per2 dependent micro RNAs revealed a selective role for miR-21 in the regulation of hypoxia and metabolic pathways...

Increased resting metabolic rate (hypermetabolism) and skeletal muscle wasting are hallmarks of the pathophysiological stress response to severe burn trauma. However, whether these two responses occur independently in burn patients or are in fact related remains unclear. In light of recent evidence demonstrating that increased proteolysis in skeletal muscle of burned patients is accompanied by mitochondrial hypermetabolism, oxidative stress, and protein damage; in this article, we discuss the evidence for a role for the mitochondrion in skeletal muscle wasting following severe burn trauma...

Inflammation is a local response to infection and tissue damage mediated by activated macrophages, monocytes, and other immune cells that release cytokines and other mediators of inflammation. For a long time, humoral and cellular mechanisms have been studied for their role in regulating the immune response, but recent advances in the field of immunology and neuroscience have also unraveled specific neural mechanisms with interesting therapeutic potential. The so-called cholinergic anti-inflammatory pathway (CAP) has been described to control innate immune responses and inflammation in a very potent manner...

BACKGROUND: Ultrasound has been applied in fruit pre-washing processes. However, it is not sufficient to protect fruit from pathogenic infection throughout the entire storage period, and sometimes ultrasound causes tissue damage. The goal of this study was to investigate the effects of calcium chloride (10 g L(-1) ) and ultrasound (350 W at 40 kHz), separately and in combination, on fruit quality, antioxidant status, tissue Ca(2+) content and distribution along with cell wall metabolism at 20 °C for six days...

With an eye on the sequence of two Indian papers concurrently published in Diabetes Therapy, this paper analyzes skin differences among races and points to a lack of organized structured education sessions as the main cause of the high prevalence of lipodystrophy (LD) and consequent poor metabolic control. Only half of all insulin-treated patients reach their therapeutic targets worldwide. The factors involved in this are manifold, including the choice of overlong and repeatedly reused needles, as well as a failure to systematically rotate injection sites, all of which lead to skin LD...

BACKGROUND: Metformin is associated with low levels of vitamin B12 (VitB12) in patients with diabetes. The CCTG/MA.32 trial investigates the effects of metformin vs placebo on breast cancer (BC) outcomes in non-diabetic high-risk BC patients. We analyzed VitB12 at baseline and after 6 months of metformin (versus placebo) in the first 492 patients with paired blood samples. METHODS: VitB12 was analyzed centrally in baseline and 6-month fasting plasma. Levels <181 pmol/L were considered deficient, 181-221 pmol/L borderline, and ≥222 pmol/L sufficient...

There are many proposed mechanisms by which single cells can be trapped; among them is the through-hole membrane for the characterization of individual microorganisms. Due to the small scale of the fabricated pores, the construction of through-hole membranes on a large scale and with relatively large areas faces many difficulties. This paper describes novel fabrication methods for a large-area, freestanding micro/nano through-hole membrane constructed from versatile membrane materials using through-hole membranes on a microfluidic chip (THMMC)...

Reprogramming of energy metabolism is a hallmark of cancer that enables the cancer cells to meet the increased energetic requirements due to uncontrolled proliferation. One prominent example is pancreatic ductal adenocarcinoma, an aggressive form of cancer with an overall 5-year survival rate of 5%. The reprogramming mechanism in pancreatic cancer involves deregulated uptake of glucose and glutamine and other opportunistic modes of satisfying energetic demands in a hypoxic and nutrient-poor environment. In the current study, we apply systems biology approaches to enable a better understanding of the dynamics of the distinct metabolic alterations in KRAS-mediated pancreatic cancer, with the goal of impeding early cell proliferation by identifying the optimal metabolic enzymes to target...

Nesfatin/nucleobindin-2 (nesf/NUCB2), a precursor of the anorexigenic protein nesfatin-1, is selectively expressed in the hypothalamic nuclei, which are central to the regulation of the autonomic nervous system. The present study sought to investigate the involvement of nesf/NUCB2 in the regulation of blood pressure and ingestive behavior, by using nesf/NUCB2-transgenic (Tg) mice. Blood pressure and heart rates were measured under conscious and unconscious conditions. Twenty-four-hour water intake and urine volume of male nesf/NUCB2-Tg mice and their littermates in metabolic cages were measured...

BACKGROUND & AIMS: Strong compensatory responses, with reduced resting metabolic rate (RMR), increased exercise efficiency (ExEff) and appetite, are activated when weight loss (WL) is achieved with continuous energy restriction (CER), which try to restore energy balance. Intermittent energy restriction (IER), where short spells of energy restriction are interspaced by periods of habitual energy intake, may offer some protection in minimizing those responses. We aimed to compare the effect of IER versus CER on body composition and the compensatory responses induced by WL...

Drug resistance of multiple myeloma(MM) has become more and more common, and greatly decreased the survival rate of these patients. The occurence of drug-resistance involves in many factors such as bone marrow microenveronment, tumor cell self-metabolism, cytokines, specific targets and so on. In this review, the potential mechanisms of resistance to glucocorticoid/proteasome inhibitor/immunomodulatory druges are briefly expounded in the aspect of tumor cell self-metabolism, including the changes of heat slock protein expression, mRNA expression, related cytokine levels and down-regulation of thalidomid-effecting site CRBN expression...

BACKGROUND: Mesenchymal stem cells (MSCs) have entered the clinic as an Advanced Therapy Medicinal Product and are currently evaluated in a wide range of studies for tissue regeneration or in autoimmune disorders. Various efforts have been made to standardize and optimize expansion and manufacturing processes, but until now reliable potency assays for the final MSC product are lacking. Because recent findings suggest superior therapeutic efficacy of freshly administered MSCs in comparison with frozen cells, we sought to correlate the T-cell suppressive capacity of MSCs with their metabolic activity...
