Novel decorated aluminium(iii) phthalocyanine complex with the application of MWCNTs on electrodes: electrochemical non-enzymatic oxidation and reduction of glucose and hydrogen peroxide.

In this study, we performed the physicochemical and electrochemical characterization of a decorated macrocyclic aluminium(iii) phthalocyanine complex (AlTMQNCAPc). Subsequently, the AlTMQNCAPc@MWCNT/GC electrode was used for the electrochemical detection of glucose and hydrogen peroxide (HO) by cyclic voltammetry (CV), differential pulse voltammetry (DPV), and chronoamperometry (CA). Moreover, the limit of detection, linear range, and sensitivity for glucose and HO were investigated (CV: 2.

Comparative structural and functional analysis of the PGU1 protein from with other .

An endo-poly-galacturonase (PGU1) gene product is responsible for the pectolytic activity in Saccharomyces bayanus. Therefore, it is of interest to document the comparative structural and functional analysis of the PGU1 protein from Saccharomyces bayanus with those in other Saccharomyces related species. The molecular docking analyses of pectin with the different homology models of PGU1 protein from several Saccharomyces species are reported.

Fabricate, advancement, molecular docking and DNA reactivity of preferred divalent metal(II) complexes attributing ()-'-((6-hydroxybenzo[]oxazol-5-yl) methylene)isonicotinohydrazide.

A series of metal(II) complexes (=Co (II), Ni(II) and Cu(II)) supported by Schiff base ligand (=()-'-((6-hydroxybenzo[]oxazol-5-yl)methylene)isonicotinohydrazide) has been designed and developed from condensation of 6-hydroxybenzo[]oxazole-5-carbaldehyde and isoniazid. The ligand (HL) and its metal(II) complexes were structurally characterized utilizing a variety of physicochemical and spectroscopic approaches. The study shows that Schiff bases (HL) act as monobasic tridentate ONO ligand and conform to octahedral geometry according to the general formula [M(HL)].

Novel Schiff base cobalt(ii) phthalocyanine with appliance of MWCNTs on GCE: enhanced electrocatalytic activity behaviour of α-amino acids.

A novel tetra-4-{()-[(8-aminonaphthalen-1-yl)imino]methyl}-2-methoxyphenol Co(ii) phthalocyanine (CoTANImMMPPc) was synthesized using a precursor protocol and characterized electroanalytical and spectroscopic techniques. The FT-IR spectra of the synthesized compounds showed significant peaks corresponding to the functional groups of the precursors and phthalocyanine (Pc) compound. The mass and NMR spectra confirmed the formation of the target precursor compounds.

Recent Advances in Synthesis and Properties of Hybrid Halide Perovskites for Photovoltaics.

The progress made by the scientific community in emerging photovoltaic technologies over the past two decades has been outstanding. Numerous methods have been developed for the preparation of hybrid organic-inorganic perovskite solar cells. The power conversion efficiency has been up to 14% by a one-step vacuum deposition technique.

Early urinary continence recovery after robot-assisted radical prostatectomy in older Australian men.

Objective: To compare the recovery of urinary continence (UC) after robot-assisted radical prostatectomy (RARP) in men aged ≥70 and <70 years at 1-year follow-up and to assess for preoperative predictors of UC recovery, as older, healthy men with localised prostate cancer are often denied curative surgical treatment on the grounds of worse UC recovery.

Patients And Methods: In all, 262 patients with prostate cancer having undergone RARP between May 2008 and September 2012, under the care of two consultant urological surgeons at three Melbourne hospitals, were identified. Patients were categorised based on their age ≥70 and <70 years and compared with regards to two endpoints; percentage fully continent and mean pads/day at 4-6 weeks, and 3, 6, 9 and 12 months after RARP.

Spinal tuberculosis with neurological deficits.

Two hundred patients suffering from tuberculosis (TB) of the spine with neurological complications were the subjects of this review. They were graded according to the Frankel system into--A: complete neurological deficit; B: sparing of some sensation; C: sparing of sensation but no useful motor function; D: sparing of sensation and useful motor function; and E: no deficits. Investigations carried out included detailed neurological assessment, radiography, contrast myelography and, in the later stages of the study, spinal computerized tomography (CT) scan.

Management of tuberculosis of the spine with neurological complications.

Tuberculosis is still a major cause of spinal compression in the developing countries. In this study 200 patients presenting with neurological lesions secondary to tuberculosis of the spine have been classified according to the Frankel classification and the results evaluated. A combination of surgical decompression and chemotherapy is advocated.

Histology of the persistent embryonic veins in arteriovenous malformations of brain.

Arterialized venous channels in the arteriovenous malformations of the brain represent persistent embryonic veins. The configuration of these veins resembles embryonic venous channels. Their microscopic features also resembles those of the foetal cerebral veins.

Hypertrophic pachymeningitis dorsalis.

A young man developed a paraplegia of relatively sudden onset. A myelogram revealed an obstruction at the T8 level. Laminectomy at T7-9 disclosed a remarkably thick dura mater compressing the spinal cord.

Persistent embryonic veins in arteriovenous malformations of the posterior fossa.

In the arteriovenous malformations of the posterior fossa the arterial feeders and the dural venous sinuses can be identified in anatomical terminology. The arterialised veins which do not conform to adult anatomical descriptions represent the persistent embryonic veins of the metencephalic and myelencephalic segments of the developing brain. These can be identified and described when related to the embryo.

Persistent embryonic veins in the arteriovenous malformations of the dura.

The basic anatomy of the arteriovenous malformations of the dura is similar to that of the internal carotid (pial) malformations, as the arterial feeders in both these lesions arise from the internal carotid artery in the embryo. The venous drainage occurs through definite channels into the major venous sinuses. Therefore, the dural and the pial malformations should be classified together.

Persistent embryonic veins in the arteriovenous malformation of the telencephalon.

The arterial components of the telencephalic arteriovenous malformations arise from the anterior cerebral and middle cerebral arteries. The complexity of the development process in this region obscures the fundamental segmental pattern. There are three regions where the primitive pial vessels cross at right angles.

Persistent embryonic veins in the arteriovenous malformation of the diencephalon.

The diencephalic arteriovenous malformation is produced by the posterior cerebral, posterior choroidal, and anterior choroidal arteries. The abnormal arterialised vessels seen in these malformation represent dorsal and ventral diencephalic veins. The drainage of the shunted blood is primarily into the transverse sinus.

Persistent embryonic veins in arteriovenous malformations of the brain.

The course and direction of persistent foetal venous channels are easily defined in the relatively simple segmental portions of the nervous system, such as the spinal cord, the myelencephalon, the metencephalon, and the mesencephalon. In sites were embryonic development is more complicated, like the diencephalon and the telencephalon, rapid growth and folding of the cortex complicate the patterns of the foetal blood vessels. Arteriovenous malformations in such sites are correspondingly more complex.
