Política criminal de la seguridad vial y garantías constitucionales

En este trabajo pretendo de poner de manifiesto las consecuencias de los cambios introducidos por LO 15/2007, de 30 de noviembre, en relación con la delincuencia en el tráfico viario, tanto respecto de los delitos contra la seguridad en el tráfico, como en relación con los homicidios y lesiones producidos en este ámbito. Desde una perspectiva formal, se modifica la denominación del Cap. IV del Título XVII, que pasa a denominarse delitos contra la Seguridad Vial, en lugar de delitos contra la Seguridad en el Tráfico.

Papillary cystoadenoma lymphomatosum (Warthin-like) of minor salivary glands

Papillary cystadenoma lymphomatosum is a benign salivary gland tumor most frequently located in the parotid gland (Warthin"s tumor). Its presentation in other major, or in minor, salivary glands is rare. Clinically, it manifests as a slow growing tumor, fluctuant on palpation due to its cystic morphology. The treatment of choice is complete excision with wide tumor-free margins. We present a 73-year-old female patient with an asymptomatic tumor of 8 years evolution in the right posterior area of the hard palate. We performed surgical excision and a biopsy, which was reported as papillary cystadenoma lymphomatosum. During the post-operative examination carried out after 3 weeks, it was observed that the lesion had recurred. The lesion was re-operated, performing the excision with CO2 laser and including the periosteum to ensure complete resection of the tumor. At 10 months follow-up, there was no recurrence of the lesion. This article includes a review of this condition and discusses its most important clinical and pathologic features and therapeutic approaches.

Minor salivary gland tumors: a clinicopathological study of 18 cases

Introduction: Minor salivary gland tumors (MSGTs) are infrequent, representing 10-15% of all salivary neoplasms. Despite this low frequency, MSGTs conform a heterogeneous group of neoplasms characterized by a broad range of histological types. Patients and method: We identified cases of MSGT in a retrospective study of the biopsies made in the period 1997-2007 in the Service of Oral Surgery (Dental Clinic of the University of Barcelona, Spain). The data collected comprised patient age and sex, the clinical characteristics and location of the tumor, the duration of the lesion, its size, the treatment provided, and the histopathological findings. Results: Of the 18 cases of MSGT studied, 12 corresponded to women (66.7%) and 6 to men (33.3%). The great majority (94.4%) were benign tumors. The preferential location was the posterior third of the hard palate (33.2%), followed by the soft palate (16.7%) and the mucosa of the upper lip (16.7%). The histopathological diagnoses of our MSGTs comprised 10 pleomorphic adenomas (55.3%), 2 cystadenomas (11.1%), 1 myoepithelioma (5.6%), 1 sialadenoma papilliferum (5.6%), 1 basal cell adenoma (5.6%), 1 Warthin"s tumor (5.6%), 1 canalicular adenoma (5.6%), and 1 low-grade polymorphic adenocarcinoma (5.6%). Discussion and conclusions: Coinciding with our own results, the literature describes a high recurrence rate for MSGTs (5-30%) when surgical removal is incomplete. Six percent of all benign minor salivary gland tumors are considered to relapse, versus 65% of all malignant lesions. Periodic clinical controls are required, since the possibility of malignant transformation must be taken into account

A minimal i-motif stabilized by minor groove G:T:G:T tetrads

The repetitive DNA sequences found at telomeres and centromeres play a crucial role in the structure and function of eukaryotic chromosomes. This role may be related to the tendency observed in many repetitive DNAs to adopt non-canonical structures. Although there is an increasing recognition of the importance of DNA quadruplexes in chromosome biology, the co-existence of different quadruplex-forming elements in the same DNA structure is still a matter of debate. Here we report the structural study of the oligonucleotide d(TCGTTTCGT) and its cyclic analog d. Both sequences form dimeric quadruplex structures consisting of a minimal i-motif capped, at both ends, by a slipped minor groove-aligned G:T:G:T tetrad. These mini i-motifs, which do not exhibit the characteristic CD spectra of other i-motif structures, can be observed at neutral pH, although they are more stable under acidic conditions. This finding is particularly relevant since these oligonucleotide sequences do not contain contiguous cytosines. Importantly, these structures resemble the loop moiety adopted by an 11-nucleotide fragment of the conserved centromeric protein B (CENP-B) box motif, which is the binding site for the CENP-B.

La nueva política criminal de la seguridad vial. Reflexiones a propósito de la LO 15/2007, de 30 de noviembre, y del Proyecto de Reforma del Código Penal

La reforma de los delitos contra la seguridad en el tráfico operada por LO 15/2007, de 30 de noviembre, constituye la expresión de un programa político-criminal de más amplio alcance, presente en el Proyecto de Reforma del Código Penal de 2007. En este trabajo se exponen las causas de la emergencia del nuevo derecho penal de la seguridad vial a la luz del paradi gma explicativo que ofrece el derecho penal postmoderno del riesgo -sometido aquí a necesarios ajustes- y se ofrece un análisis crítico de dos de los nuevos tipos: la conducción a velocidad por encima de determinados límites (art. 379.1) y la conducción con concentraciones de alcohol en aire espirado o en sangre superiores a determinadas tasas (0.6 mgr. o 1,2 gr. respectivamente) –art. 379.2-. Igualmente se analiza la propuesta del Proyecto de Reforma del Código de elevar a la categoría de delito las imprudencias leves con resultado de muerte. Tres piezas clave de un programa que trasluce una gran desconfianza hacia el estamento judicial y un optimismo infundado en las posibilidades del derecho penal para reducir eficazmente la siniestralidad vial.

Sistema de sanciones y política criminal: un estudio de Derecho comparado europeo

El trabajo aborda una comparación de los diversos sistemas de penas estatales en Europa, con el objetivo de sistematizar los diversos modelos político-criminales y de calibrar la aflictividad de los mismos. A través de determinados indicadores se pone de relieve que los sistemas jurídicos que abren un mayor espacio a la discrecionalidad judicial en la selección y la determinación de la pena muestran una mayor moderación del rigor punitivo y están en mejores condiciones de dar respuesta a una fenomenología criminal cada vez más diversa.

Política criminal con bases empíricas en España

La dimensión real de la actual política criminal española carece de adecuados niveles de racionalidad, entre sus múltiples causas, podemos mencionar el fenómeno de la creciente dinámica punitivista, la ausencia de una adecuada cultura de evaluación, el menosprecio a la criminología, la escasa consideración de los responsables políticos hacia las opiniones expertas de la dogmática, y la constante indiferencia de ésta hacia la realidad que debe enfrentar. Se configura así un decepcionante panorama donde la política criminal real aparece como carente de una sólida base empírica. La dimensión teórica de la política criminal, no puede soslayar el aporte de las investigaciones criminológicas, ya que aquellos tendrían la virtualidad de ser condición necesaria aunque no suficiente de la utilización racional del sistema punitivo. Hay que optar por una reducción de la privación de libertad y promover otras sanciones en cuyo contenido se armonicen los conceptos de incapacitación y responsabilización. Además, se requiere el desarrollo de una victimología que se dirija a inhibir los impulsos punitivos de las víctimas en función de orientar la política criminal hacia una cultura jurídica reparatoria que enfrente la actual expansión del derecho penal.

Lack of support for the association between facial shape and aggression: a reappraisal based on a worldwide population genetics perspective

Antisocial and criminal behaviors are multifactorial traits whose interpretation relies on multiple disciplines. Since these interpretations may have social, moral and legal implications, a constant review of the evidence is necessary before any scientific claim is considered as truth. A recent study proposed that men with wider faces relative to facial height (fWHR) are more likely to develop unethical behaviour mediated by a psychological sense of power. This research was based on reports suggesting that sexual dimorphism and selection would be responsible for a correlation between fWHR and aggression. Here we show that 4,960 individuals from 94 modern human populations belonging to a vast array of genetic and cultural contexts do not display significant amounts of fWHR sexual dimorphism. Further analyses using populations with associated ethnographical records as well as samples of male prisoners of the Mexico City Federal Penitentiary condemned by crimes of variable level of inter-personal aggression (homicide, robbery, and minor faults) did not show significant evidence, suggesting that populations/individuals with higher levels of bellicosity, aggressive behaviour, or power-mediated behaviour display greater fWHR. Finally, a regression analysis of fWHR on individual"s fitness showed no significant correlation between this facial trait and reproductive success. Overall, our results suggest that facial attributes are poor predictors of aggressive behaviour, or at least, that sexual selection was weak enough to leave a signal on patterns of between- and within-sex and population facial variation.

La reforma de la Ley de Enjuiciamiento Criminal

El present treball pretén oferir al lector un estudi sobre el nou Codi Processal Penal com esborrany d'avantprojecte de Llei, realitzant un anàlisis dels aspectes més rellevants i innovadors que introdueix el citat Codi així com l’adaptació d’aquests a les realitats socials de cada temps. A més, la idea per la qual neix el treball és analitzar les raons per les quals s’ha vist necessari i important realitzar una modificació total de la actual LECrim, estudiant la forma en què el legislador enfoca el nou Codi així com el seu contingut, destacant les principals diferències que conté l’actual LECrim amb aquelles que el nou Codi pretén instaurar.

Patrícia Melo. Novela de favela y novela criminal. Género(s)

El artículo se propone reflexionar sobre dos cuestiones: ¿la «novela de favela» es novela criminal? y ¿es posible detectar aspectos de género en las «novelas de favela» de Patrícia Melo? En nuestra opinión, la «novela de favela» es literatura de la violencia, para ser más exactos de la representación de la violencia, pero, aunque a veces la frontera sea muy tenue, no responde a los paradigmas de la novela criminal. Por otra parte, y a partir del análisis de la construcción de los personajes Máiquel y Reizinho (O Matador e Inferno), creemos que sí es posible afirmar un sesgo de género en los textos de Patrícia Melo.
