BACKGROUND: The laparoscopic technique has many advantages compared with open surgery for symptomatic cholecystolithiasis. Despite these advantages, many patients complain about shoulder pain (SP) after laparoscopic cholecystectomy. The purpose of this review was to evaluate intraperitoneal instillation (IPI) of saline and local anesthesia (LA) to minimize SP. METHODS: A search ...

Recent advances in molecular genetics have allowed the determination of the genetic cause of some childhood non-syndromic deafness. In Portugal only a small proportion of families are referred to a clinical genetics service in order to clarify the etiology of the deafness and to provide genetic counseling. Consequently, there are ...

Octave equivalence occurs when an observer judges notes separated by a doubling in frequency perceptually similar. The octave appears to form the basis of pitch change in all human cultures and thus may be of biological origin. Previously, we developed a nonverbal operant conditioning test of octave generalization and transfer ...

Cell signaling in response to an array of diverse stress stimuli converges on the phosphorylation of the α-subunit of eukaryotic initiation factor 2 (eIF2). Phosphorylation of eIF2α on serine 51 results in a severe decline in de novo protein synthesis and is an important strategy in the cell's armory against ...

The principal safety concern for driving for people treated with insulin or insulin secretagogues is hypoglycaemia, which impairs driving performance. Other complications, such as those causing visual impairment and peripheral neuropathy, are also relevant to medical fitness to drive. Case control studies have suggested that drivers with diabetes pose a ...

Phospholipid scramblases (PLSCRs) are palmitoylated membrane-associating proteins. Regardless of the given names, their physiological functions are not clear and thought to be unrelated to phospholipid scrambling activities observed in vitro. Using a previously established cell line of HEK293 cells constitutively expressing human Scr3 (PLSCR3) that interacts with ALG-2 Ca2+-dependently, we ...

Histidine biosynthesis in Corynebacterium glutamicum is regulated not only by feedback inhibition by the first enzyme in the pathway, but also by repression control of the synthesis of the histidine enzymes. C. glutamicum histidine genes are located and transcribed in two unlinked loci, hisEG and hisDCB-orf1-orf2-hisHA-impA-hisFI. We constructed plasmid pK18hisDPtac ...

The standard therapy for anti-erythropoietin (EPO) antibody-mediated pure red cell aplasia (PRCA) is cyclosporine (CyA) or prednisolone (PSL) 0.5-1.0 mg/kg. However, many patients with severe chronic kidney disease (CKD) and chronic heart failure cannot tolerate such an immunosuppressive regimen. An 86-year-old man with anemia related to CKD and chronic heart failure, ...

Clinical research is a necessity if effective and safe treatments are to be developed. However, this may well include the need for research that is best described as 'invasive' in that it may be associated with some discomfort or inconvenience. Limitations in the undertaking of invasive research involving people with ...

School environment is an important determinant of psychosocial function and may also be related to mental health. We therefore investigated whether perceived school safety, a simple measure of this environment, is related to mental health problems. In a population-based sample of 11,130 secondary school students, we analysed the relationship of ...

Abundant evidence shows that chronic kidney disease (CKD) is a disease state characterized by increased sympathetic activation. Kidney injury (ischemia) plays a central role in this pathogenesis. Sympathetic excitation is associated with an increased risk of cardiovascular morbidity and mortality. Several pharmacologic strategies are developed to decrease sympathetic activity. However, ...

EBV infects more than 90% of the world population. Following primary infection, EBV persists in an asymptomatic latent state. Occasionally, it may switch to lytic infection. Latent EBV infection has been associated with several diseases, such as Burkitt lymphoma (BL). To date, there are no available drugs to target latent ...

The metabolism of residual glycerol from biodiesel synthesis by Klebsiella pneumoniae BLh-1 was investigated in this study. Batch and fed-batch cultivations were performed in bioreactors under anaerobic and oxygen limitation conditions. Results of batch cultivations showed that the main product was 1,3-propanediol (1,3-PD) in both conditions, although the higher yields ...

The glycan polysialic acid is well-known as a unique posttranslational modification of the neural cell adhesion molecule NCAM. Despite remarkable acceptor specificity, however, a few other proteins can be targets of polysialylation. Here, we recapitulate the biosynthesis of polysialic acid by the two polysialyltransferases ST8SIA2 and ST8SIA4 and highlight the ...

Lateral-flow enzyme immunochromatography coupled with an immunomagnetic step was developed for rapid detection of Listeria monocytogenes in food matrices. The target bacteria was first separated and concentrated by magnetic nanoparticles containing the enzyme and directly applied to the assay system to induce an antigen-antibody reaction without any additional steps. The ...

Hereditary cancers account for approximately 10 % of breast and ovarian cancers. Mutations of the BRCA1 and BRCA2 genes, encoding two proteins involved in DNA repair, underlie most cases of such hereditary cancers. Women with BRCA mutations develop breast cancer in 50-80 % of cases and ovarian cancer in 10-40 % of cases. ...

BACKGROUND: Traditional metrics of postoperative outcomes (morbidity and mortality) are not useful to compare minimally invasive procedures with each other. Patient reported outcomes, such as quality of life (QOL) scores, offer an alternative approach. Compared with a large body of data in cancer treatment, the responsiveness of these instruments for ...

Background A substantial proportion of solid tumors carry the BRAF V600E mutation, which causes activation of the MEK/MAPK pathway and is a poor prognostic indicator. Patients with locally advanced human cancers are often treated with external beam radiation therapy. Given the association of Raf overactivation with radioresistance, we hypothesized that, ...

Chemoselective Dieckmann cyclisation reactions may be used on oxazolidine and thiazolidine templates derived from various aldehydes to access bicyclic tetramates, which have potential as templates for chemical library construction. Bioassay against S. aureus and E. coli showed that these systems have little or no intrinsic antibacterial bioactivity. © 2013 John ...

Neuronal variability plays a central role in neural coding and impacts the dynamics of neuronal networks. Unreliability of synaptic transmission is a major source of neural variability: synaptic neurotransmitter vesicles are released probabilistically in response to presynaptic action potentials and are recovered stochastically in time. The dynamics of this process ...
