A method of optimisation of new extractants structure using the desirable function has been developed. Earlier the desirable function has been proposed by Harrington (Ind Qual Control 21: 494-498, 1965) for the optimisation of processes with several response functions. The developed method of optimisation of new extractants structure has been ...

Calcification by charophytes improves the quality of water, although most studies on calcification have only examined ecorticate species. We investigated the formation and relationship of alkalines and acids with regard to calcification on internodal cells in Chara corallina, an ecorticate species, and Chara globularis, a corticate species. We observed that ...

We previously reported that tumor mitochondrial redox state and its heterogeneity distinguished between the aggressive and the indolent breast cancer xenografts, suggesting novel metabolic indices as biomarkers for predicting tumor metastatic potential. Additionally, we reported that the identified redox biomarkers successfully differentiated between the normal breast tissue and the cancerous ...

Despite a sizeable and continuously growing literature on osteopontin and cancer the molecule has not yet found entry into clinical diagnostics. Our identification of spliced variants that are more specific for cancer than the full-length transcript has opened new possibilities for reaching this goal. Here we have developed a real-time ...

Most Escherichia coli resistant to quinolones are not haemolytic. The objective of this study was to determine the phylogroup, clonal relationship, mechanism of quinolone resistance and virulence factors in 70 haemolytic E. coli resistant to nalidixic acid. Sixty-six isolates contained the hlyA gene, belonged to phylogroup B2, and 61 of ...

Our containment trials have established cold tolerance in Nicotiana tabacum osmotin (Nt Osm) transgenic tomato (Solanum lycopersicum L. cv. Pusa Ruby). Though, the stress tolerance mechanisms have been studied at physio-biochemical levels, molecular mechanisms underlying the tolerant response are still not well studied. Therefore, quantitative transcript expression of Osmotin and ...

Sarcoidosis or sarcoid reactions, which appear as FDG-avid lesions in oncologic patients, need to be differentiated from disseminated malignancies. We aimed to promote awareness of development of sarcoidosis or sarcoid reactions after antineoplastic therapy to avoid diagnostic errors with FDG-PET/CT findings and assess the utility of FDG-PET/CT for follow-up. We ...

Transportation barriers are often cited as barriers to healthcare access. Transportation barriers lead to rescheduled or missed appointments, delayed care, and missed or delayed medication use. These consequences may lead to poorer management of chronic illness and thus poorer health outcomes. However, the significance of these barriers is uncertain based ...

Although guidelines suggest that vigorous physical activity (PA) confers "extra" benefits compared with those from moderate-intensity activity alone, the magnitude of this additional benefit is unclear. The aim was to compare the reduction in risk of hypertension (HT) and depressive symptoms (DS) for 12 yr in middle-age women who reported ...

The prevalence of mental health problems in the general population should be carefully considered. The literature has reported a high co-morbidity of medical and mental illnesses; therefore, collaborative efforts incorporating psychological services into medical settings are imperative. In Puerto Rico, this is not a regular practice in general hospitals. Improving ...

Although experimental traumatic brain injury (TBI) studies support estradiol as a neuroprotectant and potent stimulator of neuroplasticity, clinical studies suggest a negative association between endogenous estradiol profiles and mortality/poor outcomes. However, no studies have evaluated associations with cerebral spinal fluid (CSF) hormone profiles and aromatase gene (cytochrome P450 [CYP]19A1) variability ...

Historically, physicians as participants in healthcare governance were shunned because of perceived potential for conflict of interest. This maxim is being revisited as health systems begin to appreciate the value presented by physician leaders. This overview of the orthopaedist's role in healthcare governance will be addressed in three sections: first ...

Standard doses of herpes simplex virus (HSV) suppressive therapy reduce plasma HIV-1 RNA levels (0.25-0.53 log10 copies per milliliter) among HIV-1/HSV-2 coinfected persons. Postulated mechanisms for this effect include direct inhibition of HIV-1 by acyclovir or indirect reduction by decreasing HSV-associated inflammation. We hypothesized that high-dose valacyclovir would further reduce ...

Whereas functionally different, both organogenesis and wound-healing processes create zones or regions of hypoxia that persist until capillary networks are formed to facilitate oxygen and nutrient delivery. Similarly, regenerative processes within in vitro engineered tissues experience the same hypoxic regions, but without the capacity to form functional capillaries resulting in ...

The 1/2ABC formula is the method most commonly used in clinical practice to rapidly estimate intracerebral hemorrhage (ICH) volume. We aimed to compare this method with the alternative '2/3Sh' formula for both regularly and irregularly-shaped hematomas. Computed tomography (CT) images from 344 ICH patients (median volume: 16·66 ml) were retrospectively ...

Adenosine monophosphate-activated kinase (AMPK) is an energy-specific sensor within the central nervous system. In this study, we observed AMPK and its phosphorylated form (pAMPK) in the hippocampal CA1 region after 5 minutes of transient forebrain ischemia. In addition, we also investigated the effects of Compound C, an AMPK inhibitor, against ...

Primary biliary cirrhosis and primary sclerosing cholangitis share some clinical features with autoimmune hepatitis, but when features of autoimmune hepatitis are present, prognosis can be affected and immunosuppressive treatment warranted. The presence of severe interface hepatitis in primary biliary cirrhosis portends a worse prognosis and should prompt evaluation for possible ...

We first reported that electroacupuncture (EA) pretreatment at the Baihui acupoint (GV20) induces ischemic tolerance. Our recent study demonstrated that N-Myc downstream-regulated gene 2 (NDRG2) expression was up-regulated following transient focal cerebral ischemia. Therefore, we investigated whether NDRG2 was involved in the ischemic tolerance induced by EA pretreatment in rats. ...

Cholestatic liver diseases include a group of diverse disorders with different epidemiology, pathophysiology, clinical course, and prognosis. Despite significant advances in the clinical care of patients with cholestatic liver diseases, liver transplant (LT) remains the only definitive therapy for end-stage liver disease, regardless of the underlying cause. As per the ...

Lipopolysaccharide (LPS) stimulates the innate immune response in the brain through nuclear factor-kappaB (NF-kappaB) signaling. Since purinergic signals activate NF-kappaB through the P2X7 receptor (P2X7R), we investigated the roles of P2X7R in neuronal NF-kappaB phosphorylation in the mouse hippocampus under basal conditions and P2X7R deletion following LPS treatment in vivo. ...
