Myths and Misogyny: The Legal Response to Sexual Assault

Sexual assault is a persistent form of violence against women that is rooted in gender inequality. It violates the sexual integrity of the victim and can have lasting psychological and emotional effects on both victims and their families. Sexual assault is a significant social and cultural problem within Canadian society. This paper presents an examination of the problems with the legal response to sexual assault that are still prevalent within the Canadian justice system despite the many positive changes in law that have come about in the last three decades. It is divided into three main chapters. The first draws on literature from diverse disciplines to examine the ways in which rape myths continue to have a profound influence on the legal response to sexual assault. The second chapter looks specifically at the legal rules surrounding sexual history evidence and the production of third party records in sexual assault cases and the ways in which the application of these rules is fraught with complications and deficiencies that severely prejudice and harm victims of sexual assault. The third chapter presents an examination of the dubious tactics used by defence lawyers to undermine sexual assault complainants in the courtroom. Additionally, the physicality of the courtroom is assessed to demonstrate the ways in which the courtroom’s physical space and its rituals made the courtroom a frightening place for sexual assault victims

Tissue-preserving approach to extracting DNA from paraffin-embedded specimens using tissue microarray technology

Background. DNA extracted from tumor cells or normal cells contained in formalin-fixed, paraffin-embedded tissues is widely used in many laboratories. The 2 most common procedures to isolate cells for DNA extraction from paraffin-embedded tissues are scalpel microdissection and laser capture microdissection. A new tissue- and time-conserving method for rapid DNA isolation from small cores taken from paraffin-embedded tissue blocks is described in this report. Methods. DNA was extracted from small tissue cores collected from paraffin-embedded tissue blocks at the time of tissue microarray construction. The quality and quantity of the DNA extracted was compared to DNA collected by scalpel microdissection. DNA collected from tissue cores was used in polymerase chain reaction (PCR) and loss of heterozygosity (LOH) analysis. Results. The quality and quantity of DNA obtained using tissue cores was comparable to DNA obtained by traditional methods. The tissue core method of DNA extraction preserves the tissue blocks from which the cores are extracted for future use. Adequate quantities of DNA can be successfully extracted from small segments of tissue cores and used for PCR. DNA isolated by tissue microdissection and the tissue core method were comparable when used to assess allelic heterozygosity on chromosome arm 18q. Conclusion. The tissue core method of DNA isolation is reliable, tissue conserving, and time effective. Tissue cores for DNA extraction can be harvested at the same time as tissue microarray construction. The technique has the advantage of preserving the original tissue blocks for additional study as only tiny cores are removed. © 2007 Wiley Periodicals, Inc.

The Effects of a Semi-Rigid Ankle Brace on a Simulated Isolated Subtalar Joint Instability

Subtalar joint instability is hypothesized to occur after injuries to the calcaneofibular ligament (CFL) in isolation or in combination with the cervical and the talocalcaneal interosseous ligaments. A common treatment for hindfoot instability is the application of an ankle brace. However, the ability of an ankle brace to promote subtalar joint stability is not well established. We assessed the kinematics of the subtalar joint, ankle, and hindfoot in the presence of isolated subtalar instability, investigated the effect of bracing in a CFL deficient foot and with a total rupture of the intrinsic ligaments, and evaluated how maximum inversion range of motion is affected by the position of the ankle in the sagittal plane. Kinematics from nine cadaveric feet were collected with the foot placed in neutral, dorsiflexion, and plantar flexion. Motion was applied with and without a brace on an intact foot and after sequentially sectioning the CFL and the intrinsic ligaments. Isolated CFL sectioning increased ankle joint inversion, while sectioning the CFL and intrinsic ligaments affected subtalar joint stability. The brace limited inversion at the subtalar and ankle joints. Additionally, examining the foot in dorsiflexion reduced ankle and subtalar joint motion. (c) 2013 Orthopaedic Research Society

Evaluation of 15 Functional Candidate Genes for Association with Chronic Otitis Media with Effusion and/or Recurrent Otitis Media (COME/ROM)

DNA sequence variants in genes involved in the innate immune response and secondary response to infection may confer susceptibility to chronic otitis media with effusion and/or recurrent otitis media (COME/ROM). We evaluated single nucleotide polymorphisms (SNPs) in 15 functional candidate genes. A total of 99 SNPs were successfully genotyped on the Sequenom platform in 142 families (618 subjects) from the Minnesota COME/ROM Family Study. Data were analyzed for association with COME/ROM using the Generalized Disequilibrium Test (GDT). Sex and age at exam were adjusted as covariates, relatedness was accounted for, and genotype differences from all phenotypically discordant relative pairs were utilized to measure the evidence of association between COME/ROM and each SNP. SNP rs2735733 in the region of the mucin 5, subtypes A/C gene (MUC5AC) exhibited nominal evidence for association with COME/ROM (P = 0.002). Two additional SNPs from this region had P values<0.05. Other variants exhibiting associations with COME/ROM at P<0.05 included the SCN1B SNP rs8100085 (P = 0.013), SFTPD SNP rs1051246 (P = 0.039) and TLR4 SNP rs2770146 (P = 0.038). However, none of these associations replicated in an independent sample of COME/ROM families. The candidate gene variants examined do not appear to make a major contribution to COME/ROM susceptibility, despite a priori evidence from functional or animal model studies for a role in COME/ROM pathology

Understanding acute ankle ligamentous sprain injury in sports

This paper summarizes the current understanding on acute ankle sprain injury, which is the most common acute sport trauma, accounting for about 14% of all sport-related injuries. Among, 80% are ligamentous sprains caused by explosive inversion or supination. The injury motion often happens at the subtalar joint and tears the anterior talofibular ligament (ATFL) which possesses the lowest ultimate load among the lateral ligaments at the ankle. For extrinsic risk factors to ankle sprain injury, prescribing orthosis decreases the risk while increased exercise intensity in soccer raises the risk. For intrinsic factors, a foot size with increased width, an increased ankle eversion to inversion strength, plantarflexion strength and ratio between dorsiflexion and plantarflexion strength, and limb dominance could increase the ankle sprain injury risk. Players with a previous sprain history, players wearing shoes with air cells, players who do not stretch before exercising, players with inferior single leg balance, and overweight players are 4.9, 4.3, 2.6, 2.4 and 3.9 times more likely to sustain an ankle sprain injury. The aetiology of most ankle sprain injuries is incorrect foot positioning at landing – a medially-deviated vertical ground reaction force causes an explosive supination or inversion moment at the subtalar joint in a short time (about 50 ms). Another aetiology is the delayed reaction time of the peroneal muscles at the lateral aspect of the ankle (60–90 ms). The failure supination or inversion torque is about 41–45 Nm to cause ligamentous rupture in simulated spraining tests on cadaver. A previous case report revealed that the ankle joint reached 48 degrees inversion and 10 degrees internal rotation during an accidental grade I ankle ligamentous sprain injury during a dynamic cutting trial in laboratory. Diagnosis techniques and grading systems vary, but the management of ankle ligamentous sprain injury is mainly conservative. Immobilization should not be used as it results in joint stiffness, muscle atrophy and loss of proprioception. Traditional Chinese medicine such as herbs, massage and acupuncture were well applied in China in managing sports injuries, and was reported to be effective in relieving pain, reducing swelling and edema, and restoring normal ankle function. Finally, the best practice of sports medicine would be to prevent the injury. Different previous approaches, including designing prophylactice devices, introducing functional interventions, as well as change of games rules were highlighted. This paper allows the readers to catch up with the previous researches on ankle sprain injury, and facilitate the future research idea on sport-related ankle sprain injury
