#1
Gerd Bönner
Hypertensive urgency and hypertensive emergency are associated with sudden, massive rise in blood pressure. An acute increase in blood pressure to values above 180/120 mmHg is considered critical. If not treated in time, it can quickly enter a life-threatening hypertensive emergency. The symptoms or organ damage determine the assessment as a crisis or an emergency. Rapid action is required. The therapy depends on the severity and the organ involvement. However the general principal is to avoid therapeutically induced hypotension...

Xiaolei Kang, Wei Sun, Limei Cao, Ji Yang
A novel cryptomelane-Ir (cry-Ir) electrode is prepared for Ir to enter into the cryptomelane (named as cry-Mn) structure and used for aspirin degradation. This catalyst can efficiently reduce the Ir usage from 85 to 34%. Also, the onset potential of cry-Ir is about 1.40 V and the over potential is about 0.34 V at 10 mA cm(-2), indicating that cry-Ir has an excellent oxygen evolution reaction (OER) activity to produce oxidizing species and can decrease electrolytic voltage during the electro-oxidation process...

SIGNIFICANCE: Hydroxyproline is a structurally and physiologically important imino acid in animals. It is provided from diets and endogenous synthesis, and its conversion into glycine is enhances the production of glutathione, DNA, heme, and protein. Furthermore, oxidation of hydroxyproline by hydroxyproline oxidase plays an important role in cell antioxidative reactions, survival, and homeostasis. Understanding the mechanisms whereby hydroxyproline participates in metabolism and cell signaling can improve the nutrition and health of animals and humans...

Establishment of sustainable and evidence-based surveillance systems are recommended for prevention of microbial resistance by the World Health Organization (WHO). As a necessity of these surveillance systems, participants are recommended to implement an external quality assessment (EQA) program. In this scope, National Antimicrobial Resistance Surveillance System (NARSS) has been established within the Public Health Institute of Turkey (PHIT) in our country since 2011. In the scope of this surveillance, NARSS EQA program has been implemented in a cycle per year and four isolates were sent to participants per cycle every year since 2011...

BACKGROUND: Despite reporting low levels of well-being, anorexia nervosa patients express temperament traits (e.g., extraversion and persistence) necessary for high levels of life satisfaction. Nevertheless, among individuals without eating disorders, a balanced organization of the flow of time, influences life satisfaction beyond temperamental dispositions. A balanced time perspective is defined as: high past positive, low past negative, high present hedonistic, low present fatalistic, and high future...

Pb can damage the physiological function of human organs by entering the human body via food-chain enrichment. Revealing the mechanisms of maize tolerance to Pb is critical for preventing this. In this study, a Pb-tolerant maize inbred line, 178, was used to analyse transcription factors (TFs) expressed under Pb stress based on RNA sequencing data. A total of 464 genes expressed in control check (CK) or Pb treatment samples were annotated as TFs. Among them, 262 differentially expressed transcription factors (DETs) were identified that responded to Pb treatment...

BACKGROUND: Oral immunosuppressive drugs are frequently prescribed in young women with atopic dermatitis (AD). Immunocompromised patients may have a higher risk of developing high risk HPV infections, CIN and cervical carcinoma. Most literature on patients using oral immunosuppressive drugs is available in organ transplant patients. Literature on the risk of developing cervical carcinoma in AD patients treated with oral immunosuppressive drugs is lacking. At this moment there is no clear guideline/consensus on this topic, but in daily practice, questions arise concerning whether this risk is increased and whether more intensive screening in women using immunosuppressive drugs should take place...

BACKGROUND: Complicated diverticulitis after transplantation occurs in as many as 3.5% of cases and carries a 25% mortality rate. Diagnosis of complicated diverticulitis in this population can be challenging because of abnormal presentations caused by immunosuppression. Only 4 cases of fistulization after kidney transplantation are described in the literature; none occurred after simultaneous pancreas-kidney transplant. METHODS: We present a first case of a coloduodenovesical fistula in a patient 9 years after simultaneous pancreas-kidney transplant...

Salmonella enterica serovars Typhi and Paratyphi A are human-restricted pathogens and the leading causative agents of enteric fever. The Typhi colonization factor (Tcf) is a chaperone-usher fimbria, thought to play a role in the host-specificity of typhoidal serovars. Here we show that the tcf cluster (tcfABCD tinR tioA) is present in at least 25 non-typhoidal Salmonella (NTS) serovars and demonstrate its native expression in clinically-important serovars including Schwarzengrund, 9,12:l,v:-, Choleraesuis, Bredeney, Heidelberg, Montevideo, Virchow and Infantis...

Living organisms tend to find viable strategies under ambient conditions that optimize their search for, and utilization of, life-sustaining resources. For plants, a leading role in this process is performed by auxin, a plant hormone that drives morphological development, dynamics, and movement to optimize the absorption of light (through branches and leaves) and chemical "food" (through roots). Similarly to auxin in plants, serotonin seems to play an important role in higher animals, especially humans. Here, it is proposed that morphological and functional similarities between (i) plant leaves and the animal/human brain and (ii) plant roots and the animal/human gastro-intestinal tract have general features in common...

The ever-growing production of engineered nanoparticles (NPs) for use in many agricultural, commercial, consumer, and industrial applications will lead to their accidental or intentional release into the environment. Potential routes of environmental exposure include manufacturing or transport spills, disposal of NP-containing products down the drain and/or in landfills, as well as direct usage on agricultural land. Therefore, NPs will inevitably contaminate aquatic environments and interact with resident organisms...

The performance, microbial community and enzymatic activity of a sequencing batch reactor (SBR) were evaluated at different silica nanoparticles (SiO2 NPs) concentrations. SiO2 NPs concentration at 5-30mg/L had a slight inhibitory impact on the nitrogen and COD removals, whereas the phosphorus removal was obviously inhibited at 30mg/L SiO2 NPs. The rates of nitrification, nitrite reduction and phosphorus removal decreased with the increase of SiO2 NPs concentration. The nitrate reduction rate decreased at less than 5mg/L SiO2 NPs and subsequently showed an increase at 10-30mg/L SiO2 NPs...

OBJECTIVES: Although the African elephant (Loxodonta africana) is classified as endangered by the International Union for Conservation of Nature (IUCN), in some isolated habitats in southern Africa, contraception is of major interest due to local overpopulation. GnRH vaccination has been promoted as a non-invasive contraceptive measure for population management of overabundant wildlife. We tested the efficacy of this treatment for fertility control in elephant bulls. METHODS: In total, 17 male African elephants that were treated with a GnRH vaccine were examined in two groups...

Alpha-gliadin peptide 31-43 is considered to be the main peptide responsible for the innate immune response in celiac disease patients. Recent evidence indicates that peptide 31-43 rapidly enters cells and interacts with the early endocytic vesicular compartment. However, the mechanism of its uptake is not completely understood. Our aim is to characterize, isolate and identify possible cell surface proteins involved in peptide 31-43 internalization by Caco-2 cells. In this study, we used a chemical cross-linker to block peptide 31-43 on cell surface proteins, and pulled-down peptide-proteins complexes using antibodies raised against peptide 31-43...
