RESUMEN
Coral reefs are fragile and endangered ecosystems in the tropical marine and coastal environment. Thermal stress due to marine heat waves (MHW) could cause significantly negative impacts on the health conditions, i.e., bleaching of the coral ecosystem. The current study is an attempt to quantify the intensity of coral bleaching in the Andaman region in recent decades using the intensity of marine heat wave (IMHW) estimated from satellite measured sea surface temperature (SST). A linear regression model was developed between IMHW and in situ observations of percent coral bleaching (PCB) which has the slope 7.767 (of IMHW unit) and intercept (- 141.7). Further, an attempt was also made to establish the relationship between PCB and the ratio between the remote sensing reflectance (Rrs) at 443 and 531 nm to upscale the percentage of coral bleaching at synoptic scales. A significant positive correlation between the PCB and band ratio index was found (R2 = 0.72). This approach can be used for the operational monitoring of coral reef beaching in this region.

OBJECTIVE: To assess whether folic acid supplementation ameliorates hot flushes. DESIGN: Double-blind, placebo-controlled randomised trial. SETTING: Nine hospitals in England. POPULATION: Postmenopausal women experiencing ≥50 hot flushes weekly. METHODS: Women (n = 164) were randomly assigned in a 1:1 ratio to receive folic acid 5 mg tablet or placebo daily for 12 weeks. Participants recorded frequency and severity of hot flushes in a Sloan Diary daily and completed Greene Climacteric and Utian Quality of Life (UQoL) Scales at 4-week intervals. MAIN OUTCOME MEASURES: The change in daily Hot Flush Score at week 12 from randomisation based on Sloan Diary Composite Score B calculation. RESULTS: Data of 143 (87%) women were available for the primary outcome. The mean change (SD) in Hot Flush Score at week 12 was -6.98 (10.30) and -4.57 (9.46) for folic acid and placebo group, respectively. The difference between groups in the mean change was -2.41 (95% CI -5.68 to 0.87) (P = 0.149) and in the adjusted mean change -2.61 (95% CI -5.72 to 0.49) (P = 0.098). Analysis of secondary outcomes indicated an increased benefit in the folic acid group regarding changes in total and emotional UQoL scores at week 8 when compared with placebo. The difference in the mean change from baseline was 5.22 (95% CI 1.16-9.28) and 1.88 (95% CI 0.23-3.52) for total and emotional score, respectively. CONCLUSIONS: The study was not able to demonstrate that folic acid had a statistically significant greater benefit in reducing Hot Flush Score over 12 weeks in postmenopausal women when compared with placebo. TWEETABLE ABSTRACT: Folic acid may ameliorate hot flushes in postmenopausal women but confirmation is required from a larger study.

OBJECTIVE: To compare the safety and efficacy of 10% sinecatechins (Veregen® ) ointment against placebo in the treatment of usual type vulvar intraepithelial neoplasia (uVIN). DESIGN: A Phase II double-blind randomised control trial. SETTING: A tertiary gynaecological oncology referral centre. POPULATION: All women diagnosed with primary and recurrent uVIN. METHODS: Eligible patients were randomised 1:1 to receive either sinecatechins or placebo ointment (applied three times daily for 16 weeks) and were followed up at 2, 4, 8, 16, 32 and 52 weeks. MAIN OUTCOME MEASURES: The primary outcome measure, recorded at 16 and 32 weeks, was histological response (HR). Secondary outcome measures included clinical (CR) response, toxicity, quality of life and pain scores. RESULTS: There was no observed difference in HR between the two arms. However, of the 26 patients who were randomised, all 13 patients who received sinecatechins showed either complete (n = 5) or partial (n = 8) CR, when best CR was evaluated. In placebo group, three patients had complete CR, two had partial CR, six had stable disease and two were lost to follow up. Patients in the sinecatechins group showed a statistically significant improvement in best observed CR as compared with the placebo group (P = 0.002). There was no difference in toxicity reported in either group. CONCLUSION: Although we did not observe a difference in HR between the two treatment arms, we found that 10% sinecatechins application is safe and shows promise in inducing clinical resolution of uVIN lesions and symptom improvement, thus warranting further investigation in a larger multicentre study. TWEETABLE ABSTRACT: A randomised control study indicating that sinecatechins ointment may be a novel treatment for uVIN.

OBJECTIVE: The objective of present work was to develop a validated liquid chromatographic method for the estimation of palbociclib in its solid dosage forms by employing a new systematic concept. MATERIAL AND METHOD: Risk assessment and control measures were undertaken along with chemometrics assistance to establish the robust method performance for studied analytical attributes viz. analyte retention, resolution, plate number, and tailing factor. Methanol %, flow rate, and pH were found influential on the performance of studied analytical attributes and optimized using a Box-Behnken experimental design. Monte-Carlo simulation was performed to evaluate the performance of the analytical procedure. A multi-attribute monitoring liquid chromatographic method employing methanol: 0.01M KH2PO4 buffer of pH 3.5 (70:30, v/v) was used with a reversed-phase column. Flow rate at 1.2mL/min and detection at 265nm monitored peak responses. RESULT: The method efficiently separated analyte from the internal standard caffeine (resolution>16). Specificity (resolution>2.0), linearity (2-64µg/mL), accuracy (>99%) and precision (%RSD<1%) were well in accord with regulatory requirements. Further, analyte was detected at 1µg/mL and was stable over applied stress conditions. CONCLUSION: In a nutshell, the novel approach produced an accurate method for estimation of palbociclib in tablets with optimum method performance.

Enhancing the rate of decomposition or removal of organic dye by designing novel nanostructures is a subject of intensive research aimed at improving waste-water treatment in the textile and pharmaceutical industries. Despite radical progress in this challenging area using iron-based nanostructures, enhancing stability and dye adsorption performance is highly desirable. In the present manuscript alkali cations are incorporated into iron oxide nanoparticles (IONPs) to tailor their structural and magnetic properties and to magnify methyl blue (MB) removal/decomposition capability. The process automatically functionalizes the IONPs without any additional steps. The plausible mechanisms proposed for IONPs incubated in alkali chloride and hydroxide solutions are based on structural investigation and correlated with the removal/adsorption capabilities. The MB adsorption kinetics of the incubated IONPs is elucidated by the pseudo second-order reaction model. Not only are the functional groups of -OH and -Cl attached to the surface of the NPs, the present investigation also reveals that the presence of alkali cations significantly influences the MB adsorption kinetics and correlates with the cation content and atomic polarizability.
RESUMEN
INTRODUCTION: One of the most common tumors of the brain are metastatic lesions. They can present as cancer of unknown primary (CUP) and require careful determination of the site of origin of the primary. Histopathologic and immunohistochemical analysis helps to determine the primary site. AIM: To study the clinicopathological features of metastatic tumors of the brain. MATERIALS AND METHODS: All cases of surgically resected brain metastasis (solid tumor metastasis) from January 2013 to April 2015 were included in the study. The clinical details including age, gender, clinical features, and location were taken from medical records. The histopathology slides were retrieved and reviewed along with clinical and imaging findings from medical records. Immunohistochemistry was performed wherever necessary. RESULTS: Out of 1662 resected brain lesions during the study period, 69 accounted for central nervous system metastasis, of which 36 were brain metastasis and 33 were isolated spinal cord metastasis. In the 36 brain metastasis cases, 19 were cases with an unknown primary. Carcinoma lung (47.2%) was found to be the most common primary malignancy. Immunohistochemistry with cytokeratin (CK)7, CK20, and thyroid transcription factor (TTF) 1 as a primary panel in metastatic tumors is highly recommended. CONCLUSION: Metastatic tumors accounted for 4.1% of intracranial lesions. Histopathologic pattern and immunohistochemistry aid in the accurate diagnosis of the original site of malignancy.

BACKGROUND: The British Society of Paediatric and Adolescent Gynaecology (BritSPAG) was created in 2000 with specific aims to include raising the profile of paediatric and adolescent gynaecology (PAG) within the United Kingdom (UK). The Society has since developed a set of clinical standards for all acute hospitals providing gynaecological services to enable successful provision of paediatric and adolescent gynaecology care. AIMS: To determine the depth of knowledge that obstetric and gynaecology trainees have with regards to the PAG services provided at their Hospital, reflecting how widely PAG services have had an impact on trainees. METHOD: The national survey was distributed to all deaneries in the UK for circulation to all their trainees via e mail during Nov 2017-March 2018. RESULTS: 28% of the trainees said there was a PAG clinic at their hospital, 46.9% did not have a clinic and 24.7% were unsure. 41.6% of the respondents were aware of BritSPAG, however only 10.4% were aware of the BritSPAG clinical standards for service planning with regards to PAG clinics. Nearly half were aware of the PAG specialist centre for their region but only 6.5% were aware of the BritSPAG UK map of services. A large majority (93.24%) didn't believe that trainees in O&G received adequate exposure to PAG in their training. CONCLUSION: This study represents the largest and first national survey to seek obstetric and gynaecology trainees' thoughts on the provision of PAG training in the UK today. Given that only 28% of trainees answering said that they were aware of a PAG clinic at their hospital, this indicates not only that many hospitals did not have a dedicated PAG clinic but more worryingly five of the trainees were not aware of the existence of a confirmed PAG clinic at their hospital, and therefore are potentially losing out on training opportunities. Disappointingly the results of our survey reveal that trainees in Obstetrics and Gynaecology still have very little experience or exposure to PAG during their training despite there being opportunities to do so.

BACKGROUND: We aimed to determine whether continuous auditing of the presumed depth of excision and comparing with the actual depth of excision in women having large loop excision of the transformation zone (LLETZ) improves the ability to acquire the desired depth of excision. METHODS: This was a prospective study of women submitted to a single LLETZ treatment between 2017-2018. Two senior colposcopists recorded what they presumed was the depth of excision at the time of treatment and the subsequent histopathology report provided the actual excised depth. Multiple linear regression identified independently associated parameters with the difference between presumed and actual excision depth. Non-linear regression determined the learning plateau defined as the theoretical minimal score of difference one could achieve with infinite practice. RESULTS: There were significant differences in practices with the first colposcopist using an 18-mm loop and the second colposcopist a 15-mm loop in the majority of cases. The median absolute and percentage difference between the presumed and actual excised depth was 2 mm and 16.6 % and 3.5 mm and 35.4 % for the two colposcopists, respectively. A learning plateau was identified only for the first colposcopist. We found that auditing consecutive excisions decreased significantly the difference between the presumed and actual depth of excision with a learning plateau at 2.2 mm of absolute difference and 22.6 % of percentage difference and with a learning rate of 13 cervical excisions. CONCLUSION: There might be a benefit in auditing our treatment practice as there seems to be a learning plateau through this method. HIPPOKRATIA 2018, 22(3): 113-121.
RESUMEN
AIM: The study was conducted to evaluate the attribution of antibacterial and antioxidant activity of methanolic extract of Cassia tora toward its growth promoting effect in broiler birds. MATERIALS AND METHODS: A limit test was conducted for C. tora extract in Wistar albino rats. Phytochemical screening of methanolic extract of leaves of C. tora was carried out. In-vitro antibacterial activity was measured by disc diffusion method. 1-day-old Ven Cobb broiler birds (n=90) were randomly allocated into three groups consisting of three replicates with 10 birds in each group. The birds of group T1 (Control) received basal diet, whereas birds of group T2 (Standard) received an antibiotic (Lincomycin at 0.05% in feed). The birds of group T3 (Test) received Cassia tora extract (CSE) at 0.4 g/L in drinking water in addition to basal diet. The treatment was given to birds of all the groups for 6 weeks. Antioxidant activity of C. tora was determined in blood of broiler birds. Cumulative body weight gain, feed intake, feed conversion ratio (FCR), dressing percent, and organ weight factor were evaluated to determine growth performance in broiler birds. RESULTS: Phytochemicals in C. tora were screened. Sensitivity to Escherichia coli and resistant to Staphylococcus aureus and Pseudomonas aeruginosa was observed in in-vitro antibacterial activity test. At the end of 6th week, antioxidant activity reflected significantly (p≤0.05) lower level of erythrocyte malondialdehyde and higher levels of reduced glutathione (GSH) and GSH peroxidase in broiler birds of group T2 and T3 as compared to broiler of group T1. Mean cumulative body weight gain of birds of T2 and T3 were significantly (p≤0.05) higher as compared to T1. Mean FCR of birds of group T3 decreased significantly than group T1. CONCLUSION: Supplementation of C. tora leaves extract at 0.4 g/L in drinking water improved growth performance in broiler birds due to its antimicrobial and antioxidant activity. Therefore, it could be used as an alternative to antibiotic growth promoter in poultry ration.
RESUMEN
AIMS AND OBJECTIVES: To describe clinicopathological features of surgically resected vascular malformations (VMs) of central nervous system (CNS). MATERIALS AND METHODS: Histologically diagnosed cases of VMs of CNS during April 2010-April 2014 were included. Demographic data, clinical and radiological features were obtained. Hematoxylin and eosin slides were reviewed along with Verhoeff-Van Gieson (VVG), Masson's trichrome, periodic acid-Schiff, and Perls' stains. Morphologically, cavernomas and arteriovenous malformations (AVMs) were distinguished on the basis of vessel wall features on VVG and intervening glial parenchyma. RESULTS: Fifty cases were diagnosed as VMs of CNS with an age range of 14-62 years. These included 36 cavernomas, 12 AVMs, 2 mixed capillary-cavernous angiomas. Most of the cavernoma patients (15/36) presented with seizures, whereas AVM patients (8/12) had a headache as the dominant symptom. Twenty-nine patients were reliably diagnosed on radiological features. Microscopic evidence of hemorrhage was seen in 24/36 cavernomas and 6/12 AVMs, as opposed to radiologic evidence of 10 and 4, respectively. Reactive gliosis was seen in 16 cavernomas. CONCLUSIONS: Histological features are important for classifying the VMs of CNS as there are no specific clinical and radiological features. Type of VM has a bearing on management, prognosis, and risk of hemorrhage.
RESUMEN
Control of the plasma densities and energies of the principal plasma species is crucial to induce modification of the plasma reactivity, chemistry, and film properties. This work presents a systematic and integrated approach to the low-temperature deposition of hydrogenated amorphous silicon nitride films looking into optimization and control of the plasma processes. Radiofrequency (RF) and ultrahigh frequency (UHF) power are combined to enhance significantly the nitrogen plasma and atomic-radical density to enforce their effect on film properties. This study presents an extensive investigation of the influence of combining radiofrequency (RF) and ultrahigh frequency (UHF) power as a power ratio (PR = RF : UHF), ranging from 4 : 0 to 0 : 4, on the compositional, structural, and optical properties of the synthesized films. The data reveal that DF power with a characteristic bi-Maxwellian electron energy distribution function (EEDF) is effectively useful for enhancing the ionization and dissociation of neutrals, which in turn helps in enabling high rate deposition with better film properties than that of SF operations. Utilizing DF PECVD, a wide-bandgap of â¼3.5 eV with strong photoluminescence features can be achieved only by using a high-density plasma and high nitrogen atom density at room temperature. The present work also proposes the suitability of the DF PECVD approach for industrial applications.

RESUMEN
Regulation of proline accumulation in seedlings of rice (Oryza sativa L. cv. Lunishree) was investigated. The increasing concentration of NaCl from 85 mM to 425 mM NaCl progressively increased proline content in rice. The maximum increase in proline content was recorded at 425 mM NaCl concentration as compared to control and other concentrations of NaCl. The highest significant activity of proline synthesizing enzymes, delta1-Pyrrolline-5-carboxylate synthetase, delta1-Pyrrolline-5-carboxylate reductase and Ornithine-δ- aminotransferase with lowest activity of proline hydrolysis enzymes;Proline dehydrogenase was also recorded at 425 mM NaCl salinity over control and other concentrations of NaCI with insignificant increase in the activity of delta1-Pyrrolline-5-carboxylate synthetase and Ornithine-δ-aminotransferase at 85 mM NaCI over control. It was found that the transcript of gene encoded with p5cs is up regulated about 1.35 folds under salinity stress. This gene synthesis an osmo protectant to help the plant resist the change in osmotic imbalances. Externally addition of MnCl2 at 300 mg/220 ml 1/2 strength Hoagland solution, having 1% NaCI, was also seen to increase 893.9% proline content of this variety as compared to control.

Linkage map with wide marker coverage is an essential resource for genetic improvement study for any species. Sex-averaged genetic linkage map of Labeo rohita, popularly known as 'rohu', widely cultured in the Indian subcontinent, was developed by placing 68 microsatellite markers generated by a simplified method. The parents and their F1 progeny (92 individuals) were used as segregating populations. The genetic linkage map spans a sex-averaged total length of 1462.2 cM, in 25 linkage groups. The genome length of rohu was estimated to be 3087.9 cM. This genetic linkage map may facilitate systematic searches of the genome to identify genes associated with commercially important characters and marker-assisted selection programmes of this species.

BACKGROUND: Meningiomas are uncommon neoplasms in the pediatric age group and differ in various aspects from their adult counterparts. They account for 0.4-4.6% of all primary brain tumors. AIMS: To retrospectively analyze the clinicopathological and immunohistochemical features of pediatric meningiomas. MATERIALS AND METHODS: Meningiomas in patients under 18 years of age diagnosed between January 2001 to December 2011 were analyzed retrospectively. The hematoxylin and eosin stained sections and Ki 67 labelling index (LI) were reviewed for all the cases Results: The pediatric meningiomas accounted for 1.52% of total meningiomas (15/983). The mean age at presentation was 12 years with male to female ratio of 1.5:1. The presenting symptoms were headache, seizures, and motor deficits. The histology included 9 cases (60%) of atypical meningioma (WHO grade II) followed by 4 cases (26.67%) of WHO grade-I and 2 cases (13.33%) of anaplastic meningioma (WHO grade III). Five cases had a recurrence. Ki67 LI ranged from 0.5% to 1.5% in grade I, 0.5% to 15% in grade II and 13% to 24% in grade III meningiomas. CONCLUSION: Meningiomas are rare in children and show a male preponderance. There was a higher incidence of atypical and anaplastic meningiomas in pediatric population.

BACKGROUND: Meningiomas represent about 30% of primary adult central nervous system tumors. Though slow growing, they recur, causing significant morbidity and mortality. OBJECTIVE: The objective of the following study is to grade meningiomas according to World Health Organization (WHO) 2007 criteria and to correlate the grade with degree of expression of epidermal growth factor receptor (EGFR) and p53. MATERIALS AND METHODS: Meningiomas diagnosed in the year 2010 in the Department of Pathology of our institute, were included in the study. Clinical and radiological findings were noted from medical records. The histopathology slides were reviewed and the tumors were graded according to WHO 2007 criteria. Tissue microarrays (TMA) were prepared and immunohistochemical analysis with epithelial membrane antigen, Vimentin, Ki67, EGFR and p53 was performed on the TMA slides. RESULTS: A total of 79 meningiomas diagnosed during the study period included 30 male and 49 female patients with an age range of 10-75 years. There was a female preponderance with M:F ratio of 1:1.63. EGFR was found to be higher in grade I (82.93%) compared with grade II (35.71%) and grade III tumors (20%) with an overall positivity of 60.81%. Mean p53 indices were higher in grade III (50%) compared with grade II (39.29%) and grade I tumors (38.46%) with an overall positivity of 39.44%. Ki67 labeling index (LI) was significantly high in grade III (16.4%) compared with grade II (6.46%) and grade I tumors (3.13%). CONCLUSION: EGFR expression and Ki67 LI correlated with grade of meningioma P < 0.0001 and P < 0.0001 respectively which were statistically significant whereas p53 expression did not correlate (P - 0.90).

OBJECTIVE: Ossification of the posterior longitudinal ligament (OPLL) is a complex multi-factorial disease process having both metabolic and biomechanical factors. The role of surgical intervention as well as the choice of approach weather anterior or posterior is ambiguous. The objective of this study was to assess the surgical out come and post operative functional improvement in patients with cervical OPLL at a tertiary care centre. PATIENTS AND METHODS: This prospective study included 63 patients of cervical OPLL who underwent either anterior and/or posterior surgeries in Department of Neurosurgery, Nizam's Institute of Medical Sciences, Hyderabad between June 2009 to May 2011. Patient's data including age, sex, pre and post operative functional status, radiographic findings and OPLL subtypes were recorded and analyzed over a follow up ranging up to minimum two years. RESULTS: The mean age of the patients was 51.1 (range 30-80 years) involving 14 women and 49 men. Out of 63 patients, 14 patients underwent surgery by anterior approach (corpectomy and fusion) and all of them improved (P = 0.52). 49 patients underwent surgery by posterior approach where decompressive laminectomy was performed in 40, laminectomy with instrumentation was done in 5, laminoplasty was done in 3 and 1 patient underwent both anterior and posterior surgeries. Of those who underwent posterior surgery, 40 patients improved, 7 remained the same as their preoperative status (who were having signal intensity changes on T2W MRI) and 2 patients deteriorated in the immediate post operative period and then showed gradual improvement. All the patients were followed up for 24 months. The mean pre-operative Nurick grade was 2.82 which later on improved to 2.03 post surgery (P < 0.05). Minor complications included wound infections in two patients (1.26%). CONCLUSIONS: Anterior cervical decompression and reconstruction is a safe and appropriate treatment for cervical spondylitic myelopathy in the setting of single or two level OPLL. Laminectomy or laminoplasty is indicated in patients with preserved cervical lordosis having three or more levels of involvement. Younger patients with good pre operative functional status and less than 2 levels of involvement have better outcome following anterior surgery.
