Refeeding Syndrome (RFS) is a well-known group of symptoms which occur after the introduction of enteral or parenteral nutrition in undernourished patients. Intrauterine growth restriction (IUGR) is the equivalent of postnatal RFS following the beginning of feeding. The aggressive parenteral nutrition of neonates with very low birth weight (VLBW) resulting from the termination of intrauterine transplacental nutrition is a source of biochemical disorders. The aim of this study was to analyze metabolic disorders in preterm infants during the 1st week of life and to determine the hypophosphatemia risk factors in low birth weight neonates receiving parenteral nutrition...

The ability of low pathogenic (LP) avian influenza viruses (AIV) of the subtypes H5 and H7 to mutate spontaneously to highly pathogenic (HP) variants is the main reason for their stringent control. On-the-spot evidence from the field of mutations in LPAIV to render the virus into nascent HP variants is scarce. Epidemiological investigations and molecular characterization of two spatiotemporally linked outbreaks caused by LP, and subsequently, HPAIV H7N7 in two-layer farms in Germany yielded such evidence. The outbreaks occurred within 45 days on farms 400 m apart...

BACKGROUND: A radiopharmaceutical is a combination of a non-radioactive compound with a radioactive isotope. Two isotopes: technetium- 99m (<sup>99m</sup>Tc) and fluorine-18 (<sup>18</sup>F) are worth mentioning on the rich list of isotopes which have found numerous medical applications. Their similarity is limited only to the diagnostic area of applicability. The type and the energy of emitted radiation, the half-life and, in particular, the production method demonstrate their diversity...

Hereditary pancreatitis (HP) is a progressive disease that can manifest in childhood with debilitating, relapsing pain. A total pancreatectomy and islet autotransplant (TPIAT) is a surgical option to relieve chronic pain while preserving the available beta-cell mass. The clinical course of HP is fraught with pancreatitis-related sequelae that can both necessitate and complicate a TPIAT. We describe a child with HP who developed a pancreatic pseudocyst-portal vein (PV) fistula. Active hemorrhage of the perforated PV into the pseudocyst and PV thrombosis complicated the planned TPIAT procedure and, preoperatively, required urgent image-guided stenting...

The mobilization and homing of endothelial progenitor cells (EPCs) contribute to the rapid endothelialization of tissue engineering blood vessel (TEBV). Inflammation can affect TEBV patency, and monocytes/macrophages (MM) are the main effector cells. But it is not clear how EPCs interact with MM after TEBV transplantation. Our results showed acellular materials would not directly cause acute and severe inflammatory responses but activate E-selectin expression in homing EPCs, gradually promoting the polarization of MM to the M1...

Species adulteration in herbal products (HPs) exposes consumers to health risks. Chemical and morphological methods have their own deficiencies when dealing with the detection of species containing the same active compounds in HPs. In this study, we developed a rapid identification method using the recombinase polymerase amplification (RPA) assay to detect two species, Ginkgo biloba and Sophora japonica (as adulteration), in Ginkgo biloba HPs. Among 36 Ginkgo biloba HP samples, 34 were found to have Ginkgo biloba sequences, and 9 were found to have Sophora japonica sequences...

C57BL/6 (B6) mice from Taconic Sciences (Tac) and the Jackson Laboratory (Jax) were infected with H. pylori PMSS1 (Hp) for 16 week; there was no significant difference in the gastric histologic activity index between Hp infected Tac and Jax B6. However, the degree of gastric mucous metaplasia and Th1-associated IgG2c levels in response to Hp infection were increased in Tac mice over Jax mice, whereas the colonization levels of gastric Hp were higher by 8-fold in Jax B6 compared with Tac B6. Additionally, mRNA expression of gastric Il-1β, Il-17A and RegIIIγ were significantly lower in the infected Tac compared to the infected Jax mice...

Ectopic pancreas also known as heterotopic pancreas (HP) is a rare congenital anomaly, mainly found as incidental finding during autopsy or abdominal exploration for an other condition. Incidence rate is probably underestimated as patients are mostly asymptomatic; otherwise, it is capable of producing symptoms depending on its location, size, often appearing in the 4th-to-6th decades. Complications such as inflammation, obstruction, bleeding, and malignancy degeneration must be considered. Pediatrics cases are very rare, generally concerning HP within Meckel's diverticulum, manifesting by gastrointestinal bleeding and intussusception...

Multidrug-resistant bacterial infections are being increasingly treated in clinics with polymyxins, a class of antibiotics associated with adverse effects in the kidney, nervous system, or airways of a significant proportion of human and animal patients. Although many of the resistant pathogens display enhanced virulence, a hazard of cytotoxic interactions between polymyxin antibiotics and bacterial virulence factors (VFs) has not been assessed, to date. We report here on testing paired combinations of four Pseudomonas aeruginosa VF phenazine toxins, pyocyanin (PYO), 1-hydroxyphenazine (1-HP), phenazine-1-carboxylic acid (PCA), phenazine-1-carboxamide (PCN), and two commonly prescribed polymyxin drugs, colistimethate (CMS)/colistin and polymyxin B, in three human airway cell lines, BEAS-2B, HBE-1, and CFT-1...

Additive manufacturing (AM) is the fabrication of real three-dimensional objects from metals, ceramics, or plastics by adding material, usually as layers. There are several variants of AM; among them material extrusion (ME) is one of the most versatile and widely used. In MEAM, molten or viscous materials are pushed through an orifice and are selectively deposited as strands to form stacked layers and subsequently a three-dimensional object. The commonly used materials for MEAM are thermoplastic polymers and particulate composites; however, recently innovative formulations of highly-filled polymers (HP) with metals or ceramics have also been made available...

Almost the full range of 16 haemagglutinin (HA) and nine neuraminidase subtypes of avian influenza viruses (AIVs) has been detected either in waterfowl, land-based poultry or in the environment in Bangladesh. AIV infections in Bangladesh affected a wide range of host species of terrestrial poultry. The highly pathogenic avian influenza (AI) H5N1 and low pathogenic AI H9N2 were found to co-circulate and be well entrenched in the poultry population, which has caused serious damage to the poultry industry since 2007...

Whole brain radiotherapy (WBRT) is the preferred treatment for multiple brain metastases, and patients with limited-stage small cell lung cancer undergo prophylactic cranial irradiation after complete remission. However, neurotoxicity remains a complication. In addition to protecting the hippocampus from irradiation to preserve cognitive function, it is also critical to avoid irradiating the hypothalamic-pituitary axis to preserve endocrine and immune function. This study aimed to evaluate the feasibility of delivering WBRT while protecting the hippocampus and hypothalamic-pituitary axis...

The importance of enhancing sludge dewaterability is increasing due to the considerable impact of excess sludge volume on disposal costs and on overall sludge management. This study presents an innovative approach to enhance dewaterability of anaerobic digestate (AD) harvested from a wastewater treatment plant. The combination of zero valent iron (ZVI, 0-4.0g/g total solids (TS)) and hydrogen peroxide (HP, 0-90mg/g TS) under pH3.0 significantly enhanced the AD dewaterability. The largest enhancement of AD dewaterability was achieved at 18mg HP/g TS and 2...

In the present study, we asked if the different types of stress alter neuronal plasticity markers distinctively in the frontal cortex (FCx) and in the hippocampus (Hp). To do so, we implemented various stress regimens to analyze changes evoked in these rat brain structures. We utilized several molecular techniques, including western blot, ELISA, quantitative RT-PCR, and various biochemical assays, to examine a range of proteins and subjected rats to behavioral tests to evaluate potential maladaptive alterations...

Holistic processing (HP) has long been considered a characteristic of right hemisphere (RH) processing. Indeed, holistic face processing is typically associated with left visual field (LVF)/RH processing advantages. Nevertheless, expert Chinese character recognition involves reduced HP and increased RH lateralization, presenting a counterexample. Recent modeling research suggests that RH processing may be associated with an increase or decrease in HP, depending on whether spacing or component information was used respectively...
