#1
Karen M Salamon, Kelly Lambert
BACKGROUND: Malnutrition is a significant problem in those undergoing peritoneal dialysis (PD). Factors such as gastrointestinal (GI) symptoms and the need for a fluid reduced diet can limit tolerance and thereby the efficacy of oral nutritional supplements to treat malnutrition. OBJECTIVES: To evaluate the acceptability and impact of two different forms of oral nutrition supplementation for 16 weeks on nutritional markers and quality of life of malnourished patients undergoing PD...

This case report is about an 85-year-old woman with bicuspid aortic stenosis (AS). Although preoperative multimodality imaging showed challenging anatomical aspects, transcatheter aortic valve replacement (TAVR) was selected to be performed as a less invasive alternative treatment approach, owing to her comorbidity. Postoperative transesophageal echocardiography and multidetector-row computed tomography revealed the presence of "locked-in leaflet" caused by stent distortion due to pinching by calcified native leaflets, with nodular calcification preventing the full expansion of the valve, which resulted in moderate perivalvular leakage...

This article investigates how an imported Soviet psychiatric model affected Bulgarians who experienced psychological crisis by examining therapeutic possibilities that were available and foreclosed in the People's Republic of Bulgaria. Bulgarians struggling with psychological disorders in the present day experience polar forms of marginalization: non-recognition on one extreme, and chronic medicalization on the other. Both tendencies can be traced to the Communist-period remodeling of mental healthcare, which outlawed private practice and individual-centered therapy, which reified empirically observable, physiological underpinnings of pathology while suppressing therapies that engaged with the existential context of mental illness...

BACKGROUND: Massive rotator cuff tear (RCT) can result in disability and severe pain. When conservative treatment fails, surgical treatment should be considered, as various surgical options can provide relatively satisfactory results. However, choosing an optimal treatment remains controversial. A relatively new treatment for irreparable RCT is the arthroscopic implantation of a biodegradable balloon spacer into the subacromial space. Here, we examined whether placement of this balloon spacer reduces pain and improves functional outcome in patients with an irreparable RCT...

PURPOSE: Diffuse intrinsic pontine glioma (DIPG) remains the main cause of death in children with brain tumors. Given the inefficacy of numerous peripherally delivered agents to treat DIPG, convection enhanced delivery (CED) of therapeutic agents is a promising treatment modality. The purpose of this study was to determine which MR imaging type provides the best discrimination of intratumoral heterogeneity to guide future stereotactic implantation of CED catheters into the most cellular tumor regions...

The aim of this study was to develop an effective bioaugmentation concept for anaerobic digesters treating lignocellulosic biomass such as straw. For that purpose, lignocellulose-degrading methanogenic communities were enriched on wheat straw from cow and goat rumen fluid as well as from a biogas reactor acclimated to lignocellulosic biomass (sorghum as mono-substrate). The bacterial communities of the enriched cultures and the different inocula were examined by 454 amplicon sequencing of 16S rRNA genes while the methanogenic archaeal communities were analyzed by terminal restriction fragment length polymorphism (T-RFLP) fingerprinting of the mcrA gene...

Erypoegin K is an isoflavone isolated from the stem bark of Erythrina poeppigiana. It contains a furan group at the A-ring of the core isoflavone structure and can inhibit the activity of glyoxalase I, an enzyme that catalyzes the detoxification of methylglyoxal (MG), a by-product of glycolysis. In the present study, we found that erypoegin K has a potent cytotoxic effect on human leukemia HL-60 cells. Its cytotoxic effect was much stronger than that of a known glyoxalase I inhibitor S-p-bromobenzylglutathione cyclopentyl diester...

Cold-tolerance in rice may be related to increased cellulose deposition in the cell wall, membrane fatty acids unsaturation and differential expression of several newly identified genes. Low temperature exposure during early vegetative stages limits rice plant's growth and development. Most genes previously related to cold tolerance in rice are from the japonica subspecies. To help clarify the mechanisms that regulate cold tolerance in young indica rice plants, comparative transcriptome analysis of 6 h cold-treated (10 °C) leaves from two genotypes, cold-tolerant (CT) and cold-sensitive (CS), was performed...

It is well-known that patients with diabetes mellitus have worse clinical outcomes following acute ischemic stroke. The intensifying effects of diabetes on ischemic brain injury have been shown to be mostly due to hyperglycemia, rather than the lack of insulin direct effects on brain. It is also well-approved that vanadium compounds have insulin-like and anti-diabetic effects, and the present study was designed to compare the protective effects of diabetes treatment with vanadium or insulin on ischemic/reperfused brain injury...

Pendimethalin (PM) is a dinitroaniline herbicide extensively applied against the annual grasses and broad-leaved weeds. There is no report available on PM-induced low-dose genotoxicity in human primary cells and in vivo test models. Such data gap has prompted us to evaluate the genotoxic potential of PM in human lymphocytes and rats. PM selectively binds in the minor groove of DNA by forming covalent bonds with G and C nitrogenous bases, as well as with the ribose sugar. PM induces micronucleus formation (MN) in human lymphocytes, indicating its clastogenic potential...

In contrast to the evidence regarding azacitidine (Aza), there is limited knowledge about the combination of decitabine (DAC) and donor lymphocyte infusions as salvage therapy for relapse after allogeneic stem cell transplantation (allo-SCT) so far. We retrospectively analyzed data of 36 patients with hematological (n = 35) or molecular relapse (n = 1) of acute myeloid leukemia (AML, n = 29) or myelodysplastic syndrome (MDS, n = 7) collected from 6 German transplant centers. Patients were treated with a median of 2 cycles DAC (range, 1 to 11)...

The capacity of mammal hair to absorb toxic metals and its utility in biomonitoring has been broadly studied. Though these metal-binding properties has generally been attributed to the sulphur contained in cysteine, an amino acid that forms part of keratin, there are not many experimental studies that analyze the role of sulphur in the external deposition of potentially toxic metallic elements in order to better understand the potential of hair in biomonitoring and generate better tools for differentiating between internal and external deposition of contaminants...

AIMS/HYPOTHESIS: Epidemiological studies suggest a role for Coxsackievirus B (CVB) serotypes in the pathogenesis of type 1 diabetes, but their actual contribution remains elusive. In the present study, we have produced a CVB1 vaccine to test whether vaccination against CVBs can prevent virus-induced diabetes in an experimental model. METHODS: NOD and SOCS1-tg mice were vaccinated three times with either a formalin-fixed non-adjuvanted CVB1 vaccine or a buffer control...

Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) is a key enzyme in long-term plasticity in many neurons, including in the nociceptive circuitry of the spinal dorsal horn. However, although the role of CaMKII heterooligomers in neuronal plasticity is isoform-dependent, the distribution and co-localization of CaMKII isoforms in the dorsal horn have not been comprehensively investigated. Here, quantitative immunofluorescence analysis was used to examine the distribution of the two major neuronal CaMKII isoforms, α and β, in laminae I-III of the rat dorsal horn, with reference to inhibitory interneurons and neuronal populations defined by expression of parvalbumin, calretinin, and calbindin D28k...

End stage renal disease (ESRD) invariably leads to anemia which has been mainly attributed to compromised release of erythropoietin from the defective kidneys with subsequent impairment of erythropoiesis. However, erythropoietin replacement only partially reverses anemia pointing to the involvement of additional mechanisms. As shown more recently, anemia of ESRD is indeed in large part a result of accelerated erythrocyte loss due to suicidal erythrocyte death or eryptosis, characterized by cell shrinkage and cell membrane scrambling with phosphatidylserine translocation to the cell surface...

This chapter is aimed at highlighting the recent findings concerning physiopathology, diagnosis, and management of conversion, factitious disorder, and malingering. Conversion disorder is the unintentional production of neurological symptom, whereas malingering and factitious disorder represent the voluntary production of symptoms with internal or external incentives. They have a close history and this has been frequently confounded. Practitioners are often confronted to medically unexplained symptoms; they represent almost 30% of neurologist's consultation...

Current studies were aimed to elucidate influence of magnetic field (MF) stimulation on cell viability and its effect on expression of calmodulin (CaM) and Hsp70 protein which plays a role of cell stress indicator and is a Ca(2+)-dependent CaM-binding protein. For the experimental model we have chosen U937 cell line exposed to chemical- and/or physical stress factors. Puromycin (PMC) was used as a chemical apoptosis inducer. Alternating (AC) (6.5rms mT, 35 Hz) magnetic field combined with 6 mT static (DC) component, or pulsed electromagnetic field (45 ± 5)mT, 50 Hz (PEMF) acted as physical stressors...
