TL;DR: The parathyroid glands and calcitonin cells exhibited increased activity which is evident by increased nuclear volume of these cells in exposed rats, and an increased levels of serum calcium and phosphate were observed.
Abstract: Wistar rats (male) were daily administered chlorpyrifos at a dose of 5 mg/kg b wt. and 10 mg/kg b wt. and sacrificed on 1st, 2nd, 4th, 6th, and 8th week. In chlorpyrifos exposed rats hypocalcemia, hypophosphatemia and hypomagnesemia were recorded. At later intervals an increased levels of serum calcium and phosphate were observed. The parathyroid glands and calcitonin cells exhibited increased activity which is evident by increased nuclear volume of these cells. Microsc. Res.

TL;DR: A yellow laccase has been purified and characterized from the culture filtrate of white rot fungus Coriolopsis floccosa MTCC-1177 and selectively transforms the aromatic methyl group to aromatic aldehyde group in the absence of mediator molecules.
Abstract: A laccase from the culture filtrate of white rot fungus Coriolopsis floccosa MTCC-1177 has been purified to homogeneity. The method involved concentration of the culture filtrate by ammonium sulphate precipitation and an anion exchange chromatography on diethylaminoethyl (DEAE) cellulose. Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) as well as native polyacrylamide gel electrophoresis (native-PAGE) produced single protein bands indicating that the enzyme preparation was pure. Molecular mass of the enzyme determined from SDS-PAGE analysis was 64 kDa. Using 2,6-dimethoxyphenol (DMP), 2,2′-[Azino-bis-(3-ethylbonzthiazoline-6-sulphonic acid (ABTS) diammonium salt and 4-hydroxy-3,5-dimethoxy benzaldehyde azine (syringaldazine) as the substrates, the K

m values of the laccase were found to be 112.5 μM, 5.16 s−1, 4.60 × 104 M − 1 s−1, 58 μM, 5.16 s−1, 8.90 × 104 M − 1 s−1 and 100 μM, 5.16 s−1, 5.16 × 104 M − 1 s−1, respectively. The pH and temperature optima were 5.0°C and 40°C, respectively. Activation energy for thermal denaturation of the enzyme was 36.6 kJ/mol/K. The enzyme was most stable at pH 4.0 when exposed for 1 h. The purified laccase has yellow colour and does not show absorption band around 610 nm found in blue laccases. The enzyme transforms toluene, 3-nitrotoluene and 4-chlorotoluene to benzaldehyde, 3-nitrobenzaldehyde and 4-chlorobenzaldehyde, respectively, in the absence of electron transfer mediators.
