Background Long-term feeding with a high-fat diet (HFD) induces endothelial dysfunction in mice, but early HFD-induced effects on endothelium have not been well characterized. Methods and Results Using an magnetic resonance imaging-based methodology that allows characterization of endothelial function in vivo, we demonstrated that short-term (2 weeks) feeding with a HFD to C57BL/6 mice or to E3L.CETP mice resulted in the impairment of acetylcholine-induced response in the abdominal aorta (AA), whereas, in the thoracic aorta (TA), the acetylcholine-induced response was largely preserved. check details Similarly, HFD resulted in arterial stiffness in the AA, but not in the TA. The difference in HFD-induced response was ascribed to distinct characteristics of perivascular adipose tissue in the TA and AA, related to brown- and white-like adipose tissue, respectively, as assessed by histology, immunohistochemistry, and Raman spectroscopy. In contrast, short-term HFD-induced endothelial dysfunction could not be linked to systemic insulin resistance, changes in plasma concentration of nitrite, or concentration of biomarkers of glycocalyx disruption (syndecan-1 and endocan), endothelial inflammation (soluble form of vascular cell adhesion molecule 1, soluble form of intercellular adhesion molecule 1 and soluble form of E-selectin), endothelial permeability (soluble form of fms-like tyrosine kinase 1 and angiopoietin 2), and hemostasis (tissue plasminogen activator and plasminogen activator inhibitor 1). Conclusions Short-term feeding with a HFD induces endothelial dysfunction in the AA but not in the TA, which could be ascribed to a differential response of perivascular adipose tissue to a HFD in the AA versus TA. Importantly, early endothelial dysfunction in the AA is not linked to elevation of classical systemic biomarkers of endothelial dysfunction.
Microorganisms of clinical importance frequently develop resistance to drug therapy, now a growing problem. The experience with
is a representative example of increasing multi-drug resistance. To avoid reaching a crisis in which patients could be left without adequate treatment, a new strategy is needed. Anti-microbial therapy has historically targeted the mechanisms rather than origin of drug resistance, thus allowing microorganisms to adapt and survive.
This contribution analyses the historical development (1943-2020) of the evolution of multi-drug resistance by
strains in light of Darwin's and Lamarck's theories of evolution.
Regarding the molecular origin of microbial drug resistance, genetic mutations and epigenetic modifications are known to participate. The analysis of the history of drug resistance by
evidences a gradual development of resistance to some antibiotics, undoubtedly due to random mutations together with natural selection based on environmental pressures (e.g., antibiotics),ntibiotic producing null or low mutagenic activity along with a resistance inhibitor, preferably in a single medication.Preeclampsia (PE) remains a leading cause of maternal morbidity and mortality all over the world. However, its aetiology and pathophysiology remain elusive. Platelet activating factor (PAF) is produced in response to oxidative stress and is a potent hypotensive agent. PAF acetylhydrolase (PAF-AH) inactivates PAF and is seen to decrease in normotensive women. check details The role of PAF-AH in preeclampsia has been in investigational literature, so far. The few studies done have shown a positive association of elevated levels of PAF-AH with preeclampsia. However, this marker has not been studied in the Indian population to-date and such studies are needed to elucidate the pathogenesis of this condition. Our study aimed to determine the PAF-AH activity by spectrophotometric assay in maternal plasma of 73 PE patients versus 73 normotensive controls and plasma PAF-AH mRNA expression to know the aberration of PAF-AH activity at the genetic level. Relative mRNA expression was calculated by Δ DCT method and a fold change was calhis multifactorial dreaded condition, but can also offer us a marker for early identification of women at risk. Recently, PAF-AH inhibitors like Darapladib has been tested as a therapeutic option in atherosclerosis. After studying the role of PAF-AH in the pathogenesis of PE, PAF-AH inhibitors may be used as a therapeutic tool in the future in PE.The dreadful disease malaria is one among the infectious diseases that comes in third number after the tuberculosis and HIV. This disease is spread by female Anopheles mosquito and caused by the malarial parasite sp notably Plasmodium falciparum. In this, the organism has several enzymes for processing the infection and growth mechanism and among that, the adenylosuccinate lyase is an enzyme that plays a critical role in metabolism and cellular replication via its action in the de novo purine biosynthetic pathway. Adenylosuccinate has been studied for two reaction mechanisms, and in that, the adenylosuccinate to AMP and fumarate is core important. As of now, there have been several studies indicating the reaction mechanism of adenylosuccinate lyase, this study projects the conformations of the reactant and product changes through molecular docking and molecular dynamic simulations. Adenylosuccinate bound complex involves His role in the product than the reactant complex, and the complex shows high flexibility due to fumarate. Thus, identifying the core inhibitor that binds to His rings could be a standard adenylosuccinate lyase inhibitor, that can block the malarial diseases in humans. In addition to the competitive inhibition site, we also predicted the uncompetitive ligand binding site, which suggest the alternate region to be targeted. Thus, from this work, we suggest both competitive and uncompetitive binding regions for the purpose identifying the malarial inhibitors.Duodenal adenocarcinoma is an uncommon, malignant tumor usually accompanied by a poor prognosis. We identified 3150 duodenal adenocarcinoma cases from the SEER database (1988-2013) to analyze clinical characteristics and outcomes. The Kaplan-Meier method was used to evaluate cancer-specific survival (CSS). Cox regression analysis was used to explore the prognostic factors of CSS. Adverse prognostic factors include higher tumor grade, later stage, tumor size ≥ 2cm, positive regional lymph nodes, and not undergoing surgical resection. Our results suggest, surgery is the optimal treatment for duodenal cancer, and combined radiotherapy does not improve survival.
