The convivial space – exploring teacher learning through practitioner research
In this paper we consider the pedagogic and cultural role of practitioner research (PR) in teacher learning, using a case study approach set in a secondary academy school in the West Midlands of England. We acknowledge teacher learning and its influence on pupils as complex and relational, and that this should encourage more research, not deter or reduce our thinking to false certainties. We note literature that endorses practitioner research, particularly its influence on positive identity shifts and enhanced collegiality. Through in-depth ‘acquaintance interviews’ we gathered data from six members of the Innovation Unit in the school and one senior management leader. The findings suggests that practitioner research helped them live more fulfilled lives at work. They felt PR increased their confidence, expertise and enthusiasm at work. These aspects contributed to a shift in their identities and changed the ways they felt about themselves and how they thought they were seen by others. We also explore participants'' reservations about the role of leadership in teacher learning. Finally we contextualise the rich detail of our interview data with a broader view to establish the importance of and explore connections between collegiality, Macmurray’s notions of the personal and the functional, Illich’s conviviality concept and Dewey’s notion of aesthetic learning experiences. In light of this context, we suggest that practitioner research enriches the working world of teachers, offering an alternative view to some more standardised and standardising CPD programmes
Comparison between endoscopic and microscopic approaches for surgery of pituitary tumours
Surgical techniques for resection of pituitary tumours have come a long way since it was first introduced in late 18th century. Nowadays, most pituitary surgeries are performed through trans-nasal trans-sphenoidal approach either using a microscope, or an endoscope. Herein the authors review the literature and compare these two instruments with regards to their outcomes when used for resection of pituitary tumours.
Ogilvie\u27s Syndrome
Ogilvie\u27s syndrome, also known as \u27paralytic ileus of the colon\u27, is characterised by pseudo-obstruction of the large intestine in the absence of any mechanical obstructing component; and presents as a massively distended abdomen. If left untreated, it may lead to bowel perforation or ischemia. Ogilvie\u27s syndrome usually presents as a postsurgical complication, mainly due to the lack and/or restriction of movement coupled with a possible electrolyte imbalance. Here, we present a case of a pre-surgical 63-year lady, having a right hip fracture, who came with complaints of severe abdominal pain and distension for 4 days. Abdominal X-rays showed massively dilated bowel loops. Patient was successfully managed with neostigmine administration and was discharged home

Depositional Environment of Phosphorites of the Sonrai Basin, Lalitpur District, Uttar Pradesh, India
Phosphates are regarded as one of the most important fertilizer minerals used by man. In Sonrai basin of Lalitpur the phosphorites are found to occur as lenticular and detached bodies throughout the Formation of the Bijawar Group. Individual bodies range from a few meters to about 4 km in length, and width varies from thin bands to about 125 meter with P2O5 concentration ranging from 10 to 20%. The Paleoproterozoic Bijawar Group are overlain by the Archaean Bundelkhand Basement Complex and underlain by Vindhyan Supergroup. The occurrence of phosphorites is confined to the Sonrai Formation which consists of massive to brecciated phosphorite within the lower reddish shales, with at least three bands identified. Megascopic study reveals that the brecciated phosphorite is reddish brown in color and fine to medium grained with angular fragments of chert and quartz embedded in a groundmass of iron oxides and secondary silica intercalated with minor veins of chert and iron oxides. The phosphorite horizon in the Lalitpur area is associated with pink to white brecciated massive quartzite, shale, dolomite and limestone of the basal unit. The concentration trends of certain major oxides indicate that the phosphorites are more enriched in CaO, P2O5 and SiO2 than Al2O3, Fe2O3, TiO2, Na2O and K2O. The concentration trends of trace elements reveal that the phosphorites are moderately enriched in Co, Zn, Zr, Pb, U than in Sc, Ba, V, Cr, Ni, , Rb, Sr, Y and Th. The dispersion patter, correlation coefficient and mutual relationship of significant major oxides represented by plotted diagrams, indicate that SiO2, CaO, MgO are antipathetically related with P2O5. The relationship suggests a gradual replacement among these oxides during diagenesis. High values of P2O5 and CaO in the phosphorites indicate more concentration of apatite constituent. The difference in geochemical behavior of CaO and MgO may be due to ionic substitution of Ca+2 by MgO+2 in the apatite crystal lattice during alkaline environment of the basin. The strong negative relationship between P2O5 with Fe2O3 in phosphorites may be due to leaching and/mild weathering of iron from the ores and reprecipitation along with P2O5 in the pore spaces, cavities/voids, veins, etc in highly oxidizing marine environment of the basin. The minimum evidence of organic matter, absence of sulphide minerals and lower concentration of V, Ni, and Cu suggest that the phosphorites were deposited in an oxidizing environment with slightly anaerobic to highly aerobic facies
Unani management of vesical calculus: a case report
Vesical calculus (Hisat-e-Masanah) accounts approximately 5% of all urinary tract stones. It has bimodal peaks age of incidence at 3 years in children in developing countries, and 60 years in adulthood. Despite advance technology of lithotripsy, the management of vesical calculus in children remains a challenge due to difficulty in passing of stone fragments and adverse effect of surgery. Hence alternative and safe treatment like Unani system of medicine can be adopted to avoid surgical procedure. The present paper deals with a case study in which a 10 years old male child patient suffered from a single vesical calculus was treated with Unani pharmacopeial medicine; Qurs Kaknaj (2 tablets), Qurs Kushta Hajrul Yahood (1 tablet) and Sharbat Buzoori Motadil (10 ml syrup) twice a day as oral administration, with the aim to evaluate the efficacy of drugs and to avoid surgery. Patient has shown excellent and significant result as 8×5 mm size of a stone flushed out at 3rd day of treatment without any operation
Role of intra-operative MRI (iMRI) in improving extent of resection and survival in patients with glioblastoma multiforme
Multiple intraoperative aids have been introduced to improve the extent of resection (EOR) in Glioblastoma Multiforme (GBM) patients, avoiding any new neurological deficits. Intraoperative MRI (iMRI) has been debated for its utility and cost for nearly two decades in neurosurgical literature. Review of literature suggests improved EOR in GBM patients who underwent iMRI assisted surgical resections leading to higher overall survival (OS) and progression free survival (PFS). iMRI provides real time intraoperative imaging with reasonable quality. Higher risk for new postoperative deficits with increased EOR is not reported in any study using iMRI. The level of evidence regarding prognostic benefits of iMRI is still of low quality
Prognostic significance of IDH 1 mutation in patients with glioblastoma multiforme
Focus of brain tumour research is shifting towards tumour genesis and genetics, and possible development of individualized treatment plans. Genetic analysis shows recurrent mutation in isocitrate dehydrogenase (IDH1) gene in most Glioblastoma multiforme (GBM) cells. In this review we evaluated the prognostic significance of IDH 1 mutation on the basis of published evidence. Multiple retrospective clinical analyses correlate the presence of IDH1 mutation in GBM with good prognostic outcomes compared to wild-type IDH1. A systematic review reported similar results. Based on the review of current literature IDH1 mutation is an independent factor for longer overall survival (OS) and progression free survival (PFS) in GBM patients when compared to wild-type IDH1. The prognostic significance opens up new avenues for treatment
Albumin precursorandHsp70modulatecornealwoundhealinginanorgan culturemodel
In order to investigate the role of albumin precursor and Hsp70 in corneal wound healing, we have analyzed the distribution of these proteins in wounded and non-wounded corneas of rabbits and the effects of topical applications of anti-albumin precursor and anti-Hsp70 antibodies on wound healing. Anti-albumin precursor and anti-Hsp70 antibodies were topically applied in healing corneal epithelium of rabbit eyes in organ culture. Corneas were allowed to heal in vitro for up to 120 h in serum-free medium with 5 and 10 μg/ml or without (migrating control) anti-albumin precursor/ or anti-Hsp70 antibodies. Fibronectin (Fb) (5 μg/ml) was used as a positive control. Immunofluorescence labelling was used to detect proteins in corneal epithelium at various time intervals following an epithelial defect. Delay in wound healing (pp120 h with 10 μg/ml. Additionally, immunofluoresence showed a strong co-localization of Hsp70 and albumin precursor during the active phase of wound healing. The presence of albumin precursor and Hsp70 in the epithelial compartment of the cornea indicates a role for these proteins in modulating cell behavior such as epithelial growth, adhesion or regeneration, thus contributing to corneal epithelial wound healing
