Published: July 2016

BACKGROUND: Cluster training is being increasingly used to develop muscular power. OBJECTIVE: To determine the effects of short inter-repetition rest(IRR) periods on the capacity to maintain maximal levels of power output. METHODS: In a first session, 16 active-duty soldiers performed a progressive loading test to establish the load linked to maximal power(optimal load, OL), and the half squat 1-repetition maximum. In Session 2, six individual sets of repetitions performed to failure (or a maximum of 20 repetitions) were conducted using the loads OL, low (LL, 15% below OL), and high (HL, 15% above OL) as quickly as possible. For each load, participants performed one set without rest between repetitions (CR, continuous repetition protocol), and another set with 6 s of rest between repetitions (IRR protocol). RESULTS: The number of repetitions participants performed before exceeding a power loss threshold of 15% were higher in the IRR versus the CR protocol by 218% (11 vs. 35), 86% (7 vs. 13), and 175% (4 vs. 11) for LL, OL, and HL, respectively. CONCLUSIONS: A 6 s interval between repetitions is sufficient to induce partial recovery in participants, and could therefore improve muscle power output.

Published: July 2016

BACKGROUND: Individuals with acromegaly (IwA) may have alterations in skeletal muscles. Isokinetic testing is the standard method to assess muscle performance through objective, reliable, and reproducible measures. OBJECTIVES: To assess knee muscles performance of IwA with active and controlled disease and to correlate the findings with hormone levels, handgrip strength (HGS), general fatigue, and quality of life. METHODS: Sixteen men with acromegaly (MwA), 21 women with acromegaly (WwA), and 21 healthy controls (nine men and 12 women) underwent knee isokinetic dynamometry at 75 and 240°/s as well as isometric dynamometry to assess HGS. The subjects were also assessed using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale, the Fatigue Impact Scale (FIS), and the Acromegaly Quality of Life Questionnaire (AcroQoL). RESULTS: Compared with healthy controls, MwA and WwA exhibited significant reductions in the peak moment (PM), maximum work repetition, and total work for both extension and flexion at both angular velocities. There were significant differences for the agonist/antagonist ratio at 75°/s in MwA (44% for active disease vs. 53% for controlled disease vs. 67% for the control group; P = 0.0002) and in WwA (48% for active disease vs. 58% for controlled disease vs. 66% for the control group; P = 0.0003). These patients also exhibited decreased HGS values and FACIT-F scores and increased FIS scores compared with healthy controls. There were significant correlations between measures obtained by isokinetic dynamometry, growth hormone (GH) levels, HGS values, and scores on the general fatigue questionnaires. However, GH levels were more strongly correlated with the isokinetic variables in MwA than in WwA.

ABSTRACT
We perform adaptive mesh refinement (AMR) and smoothed particle hydrodynamics (SPH) cosmological zoom simulations of a region around a forming galaxy cluster, comparing the ability of the methods to handle successively more complex baryonic physics. In the simplest, non-radiative case, the two methods are in good agreement with each other, but the SPH simulations generate central cores with slightly lower entropies and virial shocks at slightly larger radii, consistent with what has been seen in previous studies. The inclusion of radiative cooling, star formation, and stellar feedback leads to much larger differences between the two methods. Most dramatically, at

rapid cooling in the AMR case moves the accretion shock to well within the virial radius, while this shock remains near the virial radius in the SPH case, due to excess heating, coupled with poorer capturing of the shock width. On the other hand, the addition of feedback from active galactic nuclei (AGNs) to the simulations results in much better agreement between the methods. For our AGN model, both simulations display halo gas entropies of 100 keV cm2, similar decrements in the star formation rate, and a drop in the halo baryon content of roughly 30%. This is consistent with the AGN growth being self-regulated, regardless of the numerical method. However, the simulations with AGN feedback continue to differ in aspects that are not self-regulated, such that in SPH a larger volume of gas is impacted by feedback, and the cluster still has a lower entropy central core.

Published: July 2016

ABSTRACTThe ventriculus terminalis (VT) is a virtual cavity of the conus medullaris that appears during embryonic life. We presented a case with the cystic dilation of the ventriculus terminalis (CDVT) in a symptomatic patient. A 66-year-old female suffered from disturbance while walking evolving for the past 2 years. An MR image revealed a cystic dilatation of ventriculus terminalis. The patient experienced marked improvement of lower extremity strength by a fenestration of cyst and cyst-subarachnoid shunt. Treatment for asymptomatic patients seems to be the best conducted conservatively, whereas patients with focal neurological deficits seem to be best handled surgically.

ABSTRACT
Introduction: Adolescent idiopathic scoliosis is the most common type of scoliosis. A Cobb angle of 50° will progress beyond the age of spinal maturity. Surgery over bracing is advised at a Cobb angle above or equal to 50°. The aim of surgery is to bring the Cobb angle down below 50° to prevent reprogression as well as improve the quality of life. The objective of the study is to analyze the efficacy and significance in lifestyle improvement of pedicle screw-only fixation system versus the more common hybrid instrumentation system used for the surgical treatment of adolescent idiopathic scoliosis. Materials and Methods: A prospective cohort study was conducted involving two groups of patients were included in the study. One group was operated with pedicle screw-only method while the other with hybrid instrumentation system. The pre- and post-operative Cobb’s angles were taken across a follow-up of 4 years. An SRS-30 questionnaire was given in a yearly follow-up to assess the lifestyle improvement of the patient. Results: Pedicle screw-only method was significantly more effective in reducing Cobb’s angle (P = 0.0487). It was showed less loss of correction (P = 0.009) pedicle screw-only surgery was also better at reducing thoracic curves (P = 0.001). There seemed a better recovery time with pedicle screw surgery (P = 0.003). Conclusion: Pedicle screws are more effective and durable than hybrid systems at when treating adolescent idiopathic scoliosis.
Indigenous Education in Environmental Management and Conservation in Ghana: The Role of Folklore
Authors: Amlor Martin Q. , Alidza Matthew Q. 
Published: July 2016

<p>Studies into indigenous knowledge of African societies and their eco-system<strong>,</strong> and complemented by western research findings in recent years, point to a common fact that there is a complex interrelation between humans, animals, plants and their physical environment For this reason, Ghanaian societies enforce cultural laws that ensure protection and management of their natural resources. Despite the merits associated with African endowed natural environments, it is scary to note that to date, Ghana still faces serious environmental threats among which are: deforestation, annual bushfires, illegal surface mining, poor farming practices, unconventional methods of dumping human/industrial wastes and pollution of water bodies. This paper therefore attempts to investigate the causes of environmental degradation in Ghana and demonstrate how the people’s folklore can contribute to ensuring a well-conserved environment that can benefit the country’s present and future generations. </p>

Purpose To evaluate morphologic changes in the anterior segment using ultrasound biomicroscopic imaging (UBM) after phacoemulsification and foldable intraocular lens implantation (IOL). Methods Thirty-six patients with a mean age of 68.68 ± 8.44 years (range 51-89) who had phacoemulsification and foldable IOL implantation were included in this prospective study. Several anterior segment parameters including aqueous depth (AQD), trabecular meshwork-iris angle (TIA), ciliary body thickness (CBT), sclera thickness (ST), trabecular meshwork-ciliary process distance (T-CPD), iris-ciliary processes distance (I-CPD), and iris thickness (IT) were measured using UBM preoperatively and at postoperative month 2. Results There was a significant increase in AQD (p<0.001) and TIA (p<0.001) at postoperative month 2. However, CBT, ST, T-CPD, I-CPD, and IT did not significantly change (p>0.05) during the study period. Conclusions Removal of the crystalline lens results in change in the anterior segment parameters. Our results confirmed that UBM is a helpful option for the analysis of anterior segment structures both qualitatively and quantitatively.

Published: July 2016

Purpose To assess the etiology, clinical features, and outcome of choroidal neovascularization (CNV) in children. Methods We retrospectively assessed 10 eyes of 8 patients younger than 18 years diagnosed with CNV. The main clinical parameters included predisposing ocular pathologies, best-corrected visual acuity before and after treatment, characteristics of CNV, and treatment modalities. Results Two boys and 6 girls with CNV and a mean age of 13.9 years (SD 1.9, range 11-16 years) were included. Two patients developed bilateral CNV within the follow-up time. The development of CNV was secondary to the following pathologies: choroidal osteoma (n = 3), pathologic myopia (n = 1), punctate inner choroidopathy (n = 1), hereditary macular dystrophy (n = 2), and angioid streaks (n = 1). Idiopathic CNV was diagnosed in 2 children without any obvious associated ocular pathology. In 9 eyes, CNV was treated by intravitreal anti–vascular endothelial growth factor (VEGF) administration (n = 6), photodynamic therapy (n = 1), or combination therapy (n = 3). One eye remained untreated because of advanced disease. Conclusions Pediatric CNV is a rare but sight-threatening retinal disease. So far, no standard treatment has been validated. Since the establishment of intravitreal anti-VEGF therapy, laser coagulation and photodynamic therapy have lost their significance as therapy for CNV.
Novel Method for Fabrication of Samples for Cell Testing of Bioceramics in Granular form
Authors: Stefanic Martin , Zhang Xiang 
Published: July 2016

Background Bioceramic granules are a widely studied material for regeneration of human tissues, and their biological assessment with in vitro cell cultures plays a fundamental role in the development of bioceramics. Design of samples for cell testing represents an important aspect of the biological evaluation, as it dictates how cells will interact with the biomaterial. The aim of this study was to develop samples for cell testing of bioceramic granules with a novel design that would enable direct physical contacts between cells and bioceramic and improved handling properties for efficient laboratory work. The goal was to produce a bilayered polycaprolactone-bioceramic composite with polycaprolactone serving as a bottom layer and support for a uniform and dense layer of bioceramic granules (upper layer), which would be only partly embedded and physically stabilized in the polymer with at least one face of granules still free of any polymer residues and available for direct attachment of cells. Methods A novel method for preparation of samples in six steps was developed. A bilayered design of samples with exposed bioceramic particles was accomplished by the application of a water-soluble alginate as a sacrificial polymer in the method protocol. Samples were analyzed with SEM/EDX and ToF-SIMS. Results Bioceramic granules had a uniform and dense morphology and were partly embedded in the polycaprolactone support. Detailed ToF-SIMS study showed that granules were clean and free of any polymer residues. Conclusions The developed samples enable direct exposure of bioceramic granules to cells and surrounding physiological solution during cell testing, and possess improved handling characteristics.

Purpose To evaluate the dwell time and actual survival rates of peripherally inserted central catheter (PICC) placements after balloon angioplasty in patients with unexpected central venous obstructions. Materials and Methods Data were obtained on all PICC insertions performed in a tertiary care hospital from August 2008 to December 2013. Thirty-five PICCs attempted after balloon angioplasty in 25 patients (15 male and 10 female patients; mean age, 63 years). Fisher's exact test was used to test for differences in reasons for catheter removal between the groups of patients with stenosis or obstructions. Survival curves for PICC dwell time of all patients, stenosis group, and obstruction group were generated separately using Kaplan-Meier survival analysis and compared with log-rank tests. Results There were a total 21 obstructions and 14 stenoses. The overall technical success rate of PICC placement after balloon angioplasty was 94% (33 of 35 procedures). The PICC dwell time was determined for 27 PICCs and ranged from 4 to 165 days (mean, 39.6 days). Among all PICCs, 16 were removed early, resulting in an actual survival rate of 40.7% (11 of 27 PICCs). There were no significant differences in reasons for catheter removal between the stenosis and obstruction groups (p = 0.24). The dwell times for both groups were not significantly different by Kaplan-Meier analysis (p = 0.54). Conclusions PICC placement after balloon angioplasty is a good treatment option for patients with unexpected central venous lesions, and offers high technical success rates. The actual survival rate was relatively lower (40.7%) than that from previous studies.

Purpose Malignant pleural mesothelioma (MPM) is a rare cancer with a poor prognosis. We describe a case of MPM with an uncommon onset, characterized by pseudoachalasia as demonstrated with high-resolution manometry (HRM). Methods A 56-year-old man was referred to our hospital reporting worsening dysphagia. On the hypothesis of an esophageal motor disorder, the patient was referred for an HRM examination, which revealed features consistent with a diagnosis of type II achalasia. Results At the time of the first pneumatic dilation the endoscopist stopped the procedure in order to prevent perforation when he noticed only partial expansion of the pneumatic balloon. A CT scan and subsequent CT-guided excisional biopsy revealed an epithelioid pleural mesothelioma infiltrating the muscle wall. Given his good clinical condition, the patient was eligible for chemotherapy with cisplatin 75 mg/m2 and pemetrexed 500 mg/m2, resulting in a good response with partial remission of the disease and resolution of the dysphagia symptoms. Conclusions Pseudoachalasia as the first or only manifestation of mesothelioma is a rare occurrence that may expose patients to the risk of diagnostic delay. Close attention should be paid whenever a patient with symptoms and signs consistent with achalasia shows unusual features.

Purpose To test the effects of the implementation of 3D laparoscopic technology for the execution of nerve-sparing radical hysterectomy. Methods Thirty patients undergoing nerve-sparing radical hysterectomy via 3D laparoscopic (3D-LNSRH, n = 10) or open surgery (NSRH, n = 20) were studied prospectively. Results No significant differences were observed in baseline patient characteristics. Operative times were similar between groups. We compared the first 10 patients undergoing 3D-LNSRH with the last 20 patients undergoing NSRH. Baseline characteristics were similar between groups (p>0.2). Patients undergoing 3D-LNSRH had longer operative time (264.4 ± 21.5 vs 217.2 ± 41.0 minutes; p = 0.005), lower blood loss (53.4 ± 26.1 vs 177.7 ± 96.0 mL; p<0.001), and shorter length of hospital stay (4.3 ± 1.2 vs 5.4 ± 0.7 days; p = 0.03) in comparison to patients undergoing open abdominal procedures. No intraoperative complication occurred. One (10%) patient had conversion to open surgery due to technical difficulties and the inability to insert the uterine manipulator. A trend towards higher complication (grade 2 or worse) rate was observed for patients undergoing NSRH in comparison to 3D-LNSRH (p = 0.06). Considering only severe complications (grade 3 or worse), no difference was observed (0/10 vs 2/20; p = 0.54). Conclusions 3D-laparoscopic nerve-sparing radical hysterectomy is a safe and effective procedure. The implementation of 3D laparoscopic technology allows the execution of challenging operations via minimally invasive surgery, thus reducing open abdominal procedure rates. Further large prospective studies are warranted.

Published: July 2016

O ambiente aquático é, freqüentemente, alvo de agressões por compostos químicos de diversas origens que contaminam os organismos que ali habitam. Através de estudos de bioconcentração de agrotóxicos na biótica aquática, é possível se prever o impacto ambiental destes produtos. O presente trabalho tem por finalidade apresentar um programa computacional na linguagem PASCAL, que facilita o cálculo de alguns parâmetros toxicocinéticos, a usuário que trabalham com bioconcentração aquática com um modelo determinístico de um compartimento. Os parâmetros toxicocinéticos calculados pelo programa proposto auxiliam a estabelecer limites máximos de descarga de poluentes na água e oferecem subsídios para o delineamento de estudos de biomagnifição.

Published: July 2016

No presente trabalho propõe-se uma metodologia alternativa àquela descrita no Manual de Testes para Avaliação da Ecotoxicidade de Agentes Químicos do IBAMA, para avaliação da mobilidade de agrotóxicos em amostras de solo. Utilizando-se a trifluralina como modelo, foi feita a determinação da mobilidade deste agrotóxico em três diferentes solos do Estado de São Paulo, a partir da detecção da trifluralina em diferentes zonas de placas cromatográficas gasosa de alta resolução com detecção por captura de elétrons (HRGG/EDC). Os resultados encontrados foram compatíveis com os valores de mobilidade determinados por métodos radiométricos e descrito na literatura para a trifluralina. A substituição do método convencional (radiométrico) pelo método cromatográfico pode ser uma alternativo mais conveniente para a realidade brasileira.

Published: July 2016

Realizou-se experimento com o peixe "paulistinha" (Brachydanio rerio), tendo como objetivo observar o efeito tóxico do organoclorado endosulfan nas células hepáticas do peixe. Foram realizados de toxicidade aguada, sendo determinado o valor de CL 50 - 96 h de 0,0021083 mL/L e os limites de confiabilidade estabelecidos entre 0,00175 e 0,00254 mL/L para o animal em estudo. Durante o experimento os peixes foram mantidos em meio comtaminado num total de 96 h, observando os efeitos do produto nos hepatócitos a partir das primeiras 24 horas. As alterações observadas após os tempos de exposição 24 h, 48 h, 72 h, 96 h foram: descaracterização da forma celular e da membrana plasmática, lateralização nuclear, cromatina condensada na região central e núcleos picnóticos, grandes vacúolos citoplasmáticos e necrose focal. Após 48 horas de exposição as modificações permaneceram, havendo regeneração dos hepatócitos. O tecido apresentou-se mais regular, houve aumento do citoplasma e a cromatina apresentou-se mais dispersa. Os resultados indicaram que o endosulfan é altamente tóxico para o peixe Brachydanio rerio, e que, apesar da sua rápida degradação na água, ocorre o acúmulo nos tecidos após a exposição ao pesticidas. Estudos adicionais sobre a toxicidade do endosulfan a longo parazo seriam necessários, uma vez que algumas alterações histológicas sugerem evolução de neoplasias.
