    The consumption of cytostatics, pharmaceuticals prescribed in chemotherapy, is increasing every year and worldwide, along with the incidence of cancer. The presence and the temporal evolution of cytostatics in wastewaters from a Portuguese hospital center was evaluated through a 9-month sampling campaign, comprising a total of one hundred and twenty-nine samples, collected from May 2019 to February 2020. Eleven cytostatics out of thirteen pharmaceuticals were studied, including flutamide, mycophenolate mofetil and mycophenolic acid, which have never been monitored before. Target analytes were extracted and quantified by solid-phase extraction coupled to liquid-chromatography-tandem mass spectrometry analysis; the method was fully validated. All pharmaceuticals were detected in at least one sample, bicalutamide being the one found with higher frequency (detected in all samples), followed by mycophenolic acid, which was also the compound detected at higher concentrations (up to 5340 ± 211 ng/L). Etoposide, classified as carcinogenic to humans, was detected in 60% of the samples at concentrations up to 142 ± 15 ng/L. The risk from exposure to cytostatics was estimated for aquatic organisms living in receiving bodies. Cyclophosphamide, doxorubicin, etoposide, flutamide, megestrol and mycophenolic acid are suspected to induce risk. Long-term and synergic effects should not be neglected, even for the cytostatics for which no risk was estimated

    Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)This study evaluated the stress distribution based on the canine pillar geometry in human skull, using a finite element analysis. Computed tomography of human skull was used to build a finite element model, which was composed by all bony structures of canine pillar: canine eminence, canine fossa, frontal process of maxilla, glabellum and superciliary arch. A support on the bite contact of maxillary canine tooth and a resultant force of the masticatory muscles was applied in the simulation. Equivalent Von-mises and maximum principal stresses were analyzed along the structures that compose the canine pillar geometry. Von-mises stress presented high stress concentrated at the canine fossa and frontal process of maxilla. Maximum principal stress showed compression areas at the canine fossa and part of frontal process and tensile stress at canine eminence and part of the frontal process. In conclusion, the different stress areas means different force concentrations transmitted along the canine pillar geometry during a peak canine bite.This study evaluated the stress distribution based on the canine pillar geometry in human skull, using a finite element analysis.

    Forests play an important role in the global carbon balance because they offset a large portion of the carbon dioxide emitted through human activities. Accurate estimates are necessary for national reporting of greenhouse gas inventories, carbon credit trading and forest carbon management but in Portugal reliable and accessible forest carbon measurement methodologies are still lacking for some species. The objective of this study was to provide forest managers with a comprehensive database of carbon factors and equations that allows estimating stand-level carbon stocks in Pinus pinea L. (P. pinea), regardless of the tree inventory information available. We produced aboveground biomass and stem volume equations, biomass expansion factors (BEF) by component as well as wood basic density (WBD) and component carbon fraction in biomass. A root-to-shoot ratio is also presented using data from trees in which the root system was completely excavated. We harvested 53 trees in centre and south Portugal covering different sizes (6.5 to 56.3 cm), ages (10 to 45 years) and stand densities (20 to 580 trees ha–1). The results indicate that aboveground allometry in P. pinea is not comparable with other pines and varies considerably with stand characteristics, highlighting the need to develop stand-dependent factors and equations for local or regional carbon calculations. BEFaboveground decreases from open (1.33 ± 0.03 Mg m–3) to closed stands (1.07 ± 0.01 Mg m–3) due to a change in biomass allocation pattern from stem to branches. Average WBD was 0.50 ± 0.01 Mg m–3 but varies with tree dimensions and the root-to-shoot ratio found was 0.30 ± 0.03. The carbon fraction was statistically different from the commonly used 0.5 factor for some biomass components. The equations and factors produced allow evaluating carbon stocks in P. pinea stands in Portugal, contributing to a more accurate estimation of carbon sequestered by this forest type

    The trigeminal nerve, fifth equal of cranial nerves, a mixed nerve is considered by possessing motor and sensitive components. The sensitive portion takes to the Nervous System Central somesthesics information from the skin and mucous membrane of great area of the face, being responsible also for a neural disease, known as the Trigeminal Neuralgia. The aim of this study was to review the literature on the main characteristics of Trigeminal Neuralgia, the relevant aspects for the diagnosis and treatment options for this pathology. This neuralgia is characterized by hard pains and sudden, similar to electric discharges, with duration between a few seconds to two minutes, in the trigeminal nerve sensorial distribution. The pain is unchained by light touches in specific points in the skin of the face or for movements of the facial muscles, it can be caused by traumatic sequels or physiologic processes degenerative associate the vascular compression. Prevails in the senior population, frequently in the woman. In a unilateral way it attacks more the maxillary and mandibular divisions, rarely happens in a simultaneous way in the three branches of trigeminal nerve three branches.30115Adams, R.D., Victor, M., (1985) Principles of Neurology, , New York: Mc Graw-Hill Book CompanyBayer, D.B., Stenger, T.G., Trigeminal Neuralgia: An overview (1979) Oral Surgery, 48 (5), pp. 393-399. , http://dx.doi.org/10.1016/0030-4220(79)90064-1Bennetto, L., Patel, N.K., Fuller, G., (2007) Trigeminal Neuralgia and Its Management, 334, pp. 201-205. , http://dx.doi.org/10.1136/bmj.39085.614792.BE, BMJ, PMid:17255614 PMCid:1782012Brow, J.A., Percutaneous balloon compression for trigeminal Neuralgia (2009) Clinical Neurosurgery, 56, pp. 73-76. , PMid:20214036Eskandar, E., Barker, F.G., Rabinov, J.D., Case records of the Massachusetts General Hospital.

    The ossified pterygoalar ligament is formed between the lateral lamina of the pterygoid process and the infratemporal surface of the sphenoid bone or its greater wing and was not connected to the sphenoid spine. The aim of this study was to evaluate the incidence of the ossified pterygoalar ligament in Brazilian human skulls and analyzing its clinical importance. 183 Brazilian adult (between 30 to 60 years old) dry human skulls were evaluated. Was evaluated the incidence of skulls with complete or partial ossification of the pterygoalar ligament, bilaterally and unilaterally and in the presence on the right and left sides. Were found 5 skulls had the ossified pterygoalar ligament, resulting in an overall incidence of 2.73%. There was 1 skull in the presence of the incomplete ossification of the pterygoalar ligament, unilaterally and on the left side resulting in incidence of 0.54%. There were 4 skulls in the presence of the complete ossification of the pterygoalar ligament, unilaterally and on the right side resulting in incidence of 2.18%. The ossified pterygoalar ligament is a major cause of the entrapment of the lingual nerve or a branch of the mandibular nerve and may cause mandibular neuralgia. The incidence of the ossified pterygoalar ligament and the pterygoalar foramen is low in the Brazilian population. However, these structures have clinical significance as this ligament establish relationships with the ovale foramen and difficulty in accessing in this foramen in a therapeutic approach.2816971Antonopoulou, M., Piagou, M., Anagnostopoulou, S., An anatomical study of the pterygospinous and pterygoalar bars and foramina - their clinical relevance (2008) Journal of Cranio-Maxillofacial Surgery, 36 (2), pp. 104-108Das, S., Paul, S., Ossified pterygospinous ligament and its clinical implications (2007) Bratislavské Lekárske Listy, 108 (3), pp. 141-143Erdogmus, S., Pinar, Y., Celik, S., A cause of entrapment of the lingual nerve: Ossified pterygospinous ligament - A case report (2009) Neuroanatomy, 8, pp. 43-45Kapur, E., Dilberović, F., Redzepagić, S., Berhamović, E., Variation in the lateral plate of the pterygoid process and the lateral subzygomatic approach to the mandibular nerve (2000) Medicinski Arhiv, 54 (3), pp. 133-137Krmpotic-Nemanic, J., Vinter, I., Hat, J., Jalsovec, D., Mandibular neuralgia due to anatomical variations (1999) European Archives of Oto-Rhino-Laryngology, 256 (4), pp. 205-208. , DOI 10.1007/s004050050141Ludinghausen, M., Kageyama, I., Miura, M., Alkhatib, M., Morphological peculiarities of the deep infratemporal fossa in advanced age (2006) Surgical and Radiologic Anatomy, 28, pp. 284e-292eNayak, S.R., Saralaya, V., Prabhu, L.V., Pai, M.M., Vadgaonkar, R., D'Costa, S., Pterygospinous bar and foramina in Indian skulls: Incidence and phylogenetic significance (2007) Surgical and Radiologic Anatomy, 29 (1), pp. 5-7. , DOI 10.1007/s00276-006-0154-4Patnaik, W.G., Rajan Singla, K., Bala, S., Bilateral pterygo-alar bar and porus crotaphitico-buccinatorius e a case report (2001) Journal of the Anatomical Society of India, 50, pp. 161-162Peker, T., Karakose, M., Anil, A., Turgut, H.B., Gulekon, N., The Incidence of Basal Sphenoid Bony Bridges in Dried Crania and Cadavers: Their Anthropological and Clinical Relevance (2002) European Journal of Morphology, 40 (3), pp. 171-180. , DOI 10.1076/ejom.40.3.171.16686Peuker, E.T., Fischer, G., Filler, T.J., Entrapment of the lingual nerve due to an ossified pterygospinous ligament (2001) Clinical Anatomy, 14 (4), pp. 282-284. , DOI 10.1002/ca.1048Piagkou, M.N., Demesticha, T., Piagkos, G., Androutsos, G., Skandalakis, P., Mandibular nerve entrapment in the infratemporal fossa (2010) Surgical and Radiologic Anatomy, 10Shaw, J.P., Pterydospinous and pterygoalar foramina: A role in the etiology of trigeminal neuralgia?

    Emissary Foramens Of The Human Skull: Anatomical Characteristics And Its Relations With Clinical Neurosurgery [forámenes Emisarios Del Cráneo Humano: Características Anatómicas Y Sus Relaciones Con La Neurocirugía Clínica]

    Get PDF
    The recognition of emissary foramens is important not only for understanding the regional neurovascular anatomy, but also to distinguish normal from potentially abnormal structures. Thus, the aim of this study was to review the literature on anatomical and clinical aspects of the mastoid, parietal and sphenoid emissary foramens. It was found that the emissary foramen presents importance in clinical practice because it acts as a route of spread of extracranial infection to the intracranial structures and also possible complications in neurosurgery, due to its influence in the performance of techniques such as radiofrequency rhizotomy for treatment of trigeminal neuralgia. The anatomical knowledge of the emissary foramens is important due to variability in their incidence in the human skull and its relation to the dura mater sinuses.311287292Bergman, R.A., Afifi, A.K., Miyauchi, R., (1995) Illustrated Encyclopedia of Human Anatomic Variation: Opus V: Skeletal systems: CraniumBoyd, G.I., Emissary foramina of cranium in man and the anthropoids (1930) J.

    On the Nature of the Phase Transition in SU(N), Sp(2) and E(7) Yang-Mills theory

    We study the nature of the confinement phase transition in d=3+1 dimensions in various non-abelian gauge theories with the approach put forward in [1]. We compute an order-parameter potential associated with the Polyakov loop from the knowledge of full 2-point correlation functions. For SU(N) with N=3,...,12 and Sp(2) we find a first-order phase transition in agreement with general expectations. Moreover our study suggests that the phase transition in E(7) Yang-Mills theory also is of first order. We find that it is weaker than for SU(N). We show that this can be understood in terms of the eigenvalue distribution of the order parameter potential close to the phase transition.Comment: 15 page
