The effectiveness of the RSID confirmatory test kit for human alpha amylase: the effects of environmental factors and substrate materials

2016

The investment in time and money that DNA analyses involves, provides a justification for forensic laboratories to carry out prior tests to ensure the presence of biological fluid in samples. The RSID kit has already been evaluated for forensic use, but its effectiveness on forensic casework samples is almost impossible to predict. Moreover, forensic reports presented before a court of law must justify the methods used to generate their findings. Consequently, trials to know how factors – such as the characteristics of the donor, the substrate and environmental conditions – can affect the kit’s efficacy are essential. This study evaluates some of these factors. For this aim, samples were ma…

Association with the Syndrome "Basses Richesses" of Sugar Beet of a Phytoplasma and a Bacterium-Like Organism Transmitted by a Pentastiridius sp.

2002

The syndrome “basses richesses” of sugar beet (SBR) was first observed in 1991 in Burgundy, France. A cixiid planthopper, Pentastiridius beieri, has been proved to be involved in the transmission to sugar beet of a stolbur phytoplasma, which could be detected in some affected plants. In 2000, periwinkle and sugar beet exposed to field-collected cixiids developed symptoms similar to SBR on sugar beet. Use of 4′-6-diamidino-2-phenylindole (DAPI) staining and transmission electron microscopy confirmed the presence of phytoplasma in some of the plants, which were also positive for this pathogen in a polymerase chain reaction (PCR) analysis. A phloem-restricted gram-negative bacteria was seen i…

High expression of progesterone receptor may be an adverse prognostic factor in oestrogen receptor-negative/progesterone receptor-positive breast can…

2021

Oestrogen receptor (ER)-negative (–) progesterone receptor (PgR)-positive (+) is the least common combination of steroid receptor expression observed in breast cancer. There are many controversies regarding the actual existence of ER–/PgR+ phenotype. In the current study, we aimed to perform comprehensive immunohistochemical re-evaluation of ER–/PgR+ breast cancers from multiple institutions. A total of 135 cases of ER–/PgR+ breast cancer were collected from 11 institutions from the period 2006–2020 and subsequently stained with three clinically validated anti-ER antibody clones: SP1 (Roche), 1D5 (Dako), and EP1 (Dako), and two anti-PgR antibody clones: 636 (Dako), and 1E2 (Roche). Clinicop…

Use of the software ‘Poser4’ in reconstruction of accident and crime scenes

2000

The reconstruction of accident and crime scenes demands the full attention of the forensic working physician. Description by words is often difficult and liable to be misunderstood. Reconstruction in the original places of events are expensive and in some cases impossible. Computer graphics and animations give the possibility to construct the original course of events. Poser4 is a software package to perform these reconstructions in an easy and vivid way. We investigated the possibilities of reconstructing an accident with this software.

Problematic internet use prior to and during the COVID-19 pandemic

2021

The health and socio-economic challenges arising from the COVID-19 pandemic have led to greater reliance on the internet to meet basic needs and responsibilities. Greater engagement in online activities may have negative mental and physical health consequences for some vulnerable individuals, particularly under mandatory self-isolation or ‘lockdown’ conditions. The present study investigated whether changes in levels of involvement in online activities during the COVID-19 pandemic (i.e., watching TV series,online sexual activities, video games, social networks, gambling, online shopping, and instant messaging) were associated with problematic internet use, as well as whether certain psychol…

Patología de los tumores neuroblásticos: evaluación pronóstica. Experiencia del centro español de referencia de la SEOP para estudios biopatológicos …

2007

Resumen Antecedentes Los tumores neuroblasticos son los tumores solidos extracraneales mas frecuentes en la infancia y se caracterizan por una evolucion clinica heterogenea que va desde una progresion rapida a una regresion tumoral espontanea. Existen factores pronosticos conocidos que determinan dicha evolucion como son la edad, estadiaje, histopatologia, estatus de MYCN, ploidia y diversas ganancias y perdidas cromosomicas. El objetivo del trabajo es describir nuestra experiencia como laboratorio de referencia espanol para la determinacion de estos parametros pronosticos. Metodos Material tumoral de pacientes con neuroblastoma, remitido a nuestro laboratorio desde 1992 hasta 2005, ha sido…
