Metaphyseal growth arrest lines in psychosocial short stature

Metaphyseal growth arrest lines are seen in children who experience significant physical stress such as infection or malnutrition over a sufficient period of time. These lines have not been reported previously in children with psychosocial short stature (PSS). Two boys and a girl with PSS with metaphyseal growth arrest lines on skeletal radiographs at the time of maximal stress in their homes are described. All three had reversible growth hormone insufficiency during admission, which is pathognomic for PSS. Multiple growth arrest lines in the distal end of the radius or vertebrae should alert clinicians to an alternative diagnosis in a child with growth hormone insufficiency. This may provide a clue to the diagnosis of occult PSS.     

Quercetin Attenuates Benzo(α)pyrene-induced CYP1A Expression

<正>We studied effects of nutrient quercetin on cytochromes’Р450 1А(CYP1A)activities(measured spectrofluorimetrically using 7-ethoxy-resorufin for CYP1A1 and 7-methoxy-resorufin for CYP1A2 as substrates),on mR NA levels(measured by RT-PCR),and on DNA-binding activities(evaluated by an electrophoretic mobility shift assay)of proteins regulating CYP1A expression in untreated and benzo(α)pyrene(Ba P)-treated rats.Wistar rats     

Reversible “Pulvinar sign” in Wernicke's encephalopathy

Young onset dementia is a challenge. We describe a case, where a patient presented with psychosis, dementia and MRI showing pulvinar sign, all of this typical of variant Cruetzfelt Jacob disease (CJD). Subsequent investigations lead to the diagnosis of a treatable illness and patient was improved and MRI sign reversed, underlining again the importance of search needed for treatable diseases in any “typical” case of fatal illness.     

Antidiabetic and antioxidant potentials of spent turmeric oleoresin,a by-product from curcumin production industry

ObjectiveTo investigate the antidiabetic and antioxidant activity of spent turmeric oleoresin (STO).MethodsAntidiabetic activity of STO evaluated by α-amylase and α-glucosidase enzyme inhibition assays. The antioxidant capacity studied by DPPH., ABTS., superoxide radical scavenging and metal chelating activity methods.ResultsThe STO showed good antidiabetic activity by inhibiting key enzymes linked to type 2 diabetes, viz α-glucosidase and α-amylase with an IC50values of 0.71 and 0.16μg/mL respectively. The IC₅₀values for DPPH. and ABTS. assay were 58.1 and 33 μg/mL respectively. STO effectively scavenged the superoxide free radical with an IC50 value of 61.5μg/mL and showed a moderate iron chelation property.ConclusionsThe above study reveals that the spent turmeric oleoresin being wasted at present can be used as antioxidant and antidiabetic agent in food and neutraceutical products.
