BACKGROUND: A considerable number of patients suffer delayed neurological deficits even after a successful removal of intramedullary spinal cord ependymoma. The underlying pathology remains unknown. Radiological findings could be an explanation for poor outcome after surgery. METHODS: We conducted a retrospective study of all cases treated from 1980 to 2016 in our department. Included were all patients with intramedullary spinal cord ependymoma treated with microsurgical excision...

Very little research has been conducted to show the way in which criminal behavior unfolds over the life-course in children who have been sexually abused, and whether it differs from the 'age-crime' patterns consistently documented in the criminology literature. This study investigated the temporal pathways of criminal offending between the ages of 10-25 years among medically confirmed cases of child sexual abuse (CSA), and considered whether abuse variables, offense variables, and the presence of other adverse outcomes, were associated with heterogeneity in offending pathways among CSA survivors...

BACKGROUND: Calcineurin-inhibitor-induced pain syndrome (CIPS) was used as a reference in the literature as reflex sympathetic dystrophy syndrome related to calcineurin inhibitors. Much of the literature describes CIPS that occurred after kidney and bone marrow transplantation. We describe a rare case of CIPS in induction immunosuppression before kidney transplantation, under administration of an anti-rheumatoid drug. METHODS: A 53-year-old woman had pre-status of ABO-incompatible living kidney transplantation...

BACKGROUND: The delta-shaped anastomosis has been reported to reduce anastomotic complications for a decade. However, little has been written comparing this technique with the circular stapler technique. The objective of this retrospective study was to assess the safety and efficacy of cervical delta-shaped anastomosis after esophagectomy. METHODS: Medical records of patients with esophageal squamous cell carcinoma who underwent McKeown (three-incision) esophagectomy between September 2013 and June 2015 were reviewed...

The iliopsoas of the rat is composed of two muscles - the psoas major muscle and the iliacus muscle. The psoas major muscle arises from all the lumbar vertebrae and the iliacus muscle from the fifth and sixth lumbar vertebrae and ilium. Their common insertion point is the lesser trochanter of the femur, and their common action is the lateral rotation of the femur and flexion of the hip joint. Unlike humans, the rat is a quadruped and only occasionally rises up on its hind legs. Therefore, it is expected that the fibre type composition of the rat iliopsoas muscle will be different than that of humans...

Perinatal skeletal muscle growth rates are a function of protein and myonuclear accretion. Precocious exposure of the fetus to glucocorticoids (GLC) in utero impairs muscle growth. Reduced muscle protein synthesis rates contribute to this response, but the consequences for myonuclear hyperplasia are unknown. To test the hypothesis that blunting of Pax7+ muscle progenitor cell proliferative activity by GLC in vivo also contributes to reduced fetal muscle growth, pregnant rats were administered dexamethasone (DEX;1 mg/L drinking water) from embryonic day (ED) 13 to ED21...

INTRODUCTION: A perception exists that there are few benefits of a paediatric assessment in historic child sexual abuse (CSA), as the likelihood of finding forensic evidence is low. AIM: To determine the value of a comprehensive paediatric assessment in a dedicated clinic for children and young people who present following suspicion or allegation of historic CSA. METHOD: All children with suspected or alleged historic CSA, defined as >7 days after the last episode of sexual assault in pubertal girls, or >3 days for prepubertal girls and all boys, were assessed in a specialised paediatric clinic...

The present study aimed to develop an amorphous solid dispersion (ASD) of cyclosporine A (CsA) by a fine droplet drying (FDD) process for improvement in oral absorption of CsA. CsA and hydroxypropyl cellulose-SSL were dissolved in 1,4-dioxane, and the solution was powdered by the FDD process to obtain the ASD formulation of CsA (ASD/CsA). The ASD/CsA was characterized in terms of morphology, particle size distribution, crystallinity, dissolution behavior, physicochemical stability, and pharmacokinetic behavior in rats...

BACKGROUND: Considerable variability exists in normal developmental lumbar spinal canal size. This impacts the likelihood of neural compromise. Spinal canal development is complete by 17 years. As diseases incurred thereafter do not knowingly affect the developmental size of the spinal canal, it is reasonable to use a selected population undergoing abdominopelvic computed tomography (CT) examination to determine developmental lumbar spinal canal size. METHODS: Study approval was granted by the Clinical Research Ethics Committee...

BACKGROUND: Cannabidiol (CBD) is a naturally occurring constituent of the marijuana plant. In the past few years, there has been great interest in the therapeutic effects of isolated CBD and it is currently being explored for numerous disease conditions (e.g., pain, epilepsy, cancer, various drug dependencies). However, CBD remains a Schedule I drug on the U.S. Controlled Substances Act (CSA). Despite its status, there are no well-controlled data available regarding its abuse liability...

INTRODUCTION: Muscle fiber cross-sectional area (CSA) and proportion of different fiber types are important determinants of muscle function and overall metabolism. Genetic variation plays a substantial role in phenotypic variation of these traits, however, the underlying genes remain poorly understood. AIMS: This study aimed to map quantitative trait loci (QTL) affecting differences in soleus muscle fiber traits between the LG/J and SM/J mouse strains. METHODS: Fiber number, CSA, and proportion of oxidative type I fibers were assessed in the soleus of 334 genotyped male and female mice of the F34 generation of advanced intercross lines (AIL) derived from the LG/J and SM/J strains...

There is clinical and experimental evidence that treatment with immunosuppressive and antiproliferative drugs such as the calcineurin inhibitor cyclosporine A (CsA) is associated with mental health problems and neuropsychological disturbances in patients. However, it remains unclear whether and to what extent cognitive functions such as memory and attention processes are affected by the pharmacological treatment. This is partly because of the fact that it is difficult to refer the observed neuropsychological disturbances in patients to the drug itself, to drug-induced immune suppression, or to interaction with other medication or comorbidities...

BACKGROUND: Childhood sexual abuse (CSA) can have a serious effect on general and obstetric health. Breastfeeding includes several triggers for memories of abuse experiences, which will likely influence decisions about breastfeeding and its implementation in daily life. This is important since breastfeeding improves maternal well-being and bonding with the child. Research aim: As breastfeeding strongly influences the long-term health of children, we investigated experiences with breastfeeding in women with a history of CSA...

Proton/fluoride spin-lattice (T1) nuclear magnetic relaxation dispersion (NMRD) measurements of 1-butyl-3-methyl-1H-imidazolium hexafluorophosphate, [C4mim][PF6], have been carried out using high field spectrometers and a fast-field-cycling instrument at proton Larmor frequencies ranging from 10 kHz to 40 MHz, at different temperatures. The NMRD profiles are interpreted by means of a simple relaxation model based on the inter- and intra-ionic dipole-dipole relaxation mechanism. Using an atomic molecular-ion dynamic simulation at 323 K the relevant spin dipole-dipole (DD) correlation functions are calculated...

BACKGROUND: Previous studies suggested that supplementation of lactating sows with β-hydroxy-β-methylbutyrate (HMB) could improve the performance of weaning pigs, but there were little information in the muscle fiber type transformation of the offspring and the subsequent performance in pigs from weaning through finishing in response to maternal HMB consumption. The purpose of this study was to determine the effect of supplementing lactating sows with HMB on skeletal muscle fiber type transformation and growth of the offspring during d 28 and 180 after birth...

Acute kidney injury (AKI) is frequently observed after cardiac surgery (CS) with cardiopulmonary bypass (CPB). Multiple mechanisms underlie this phenomenon, including CPB-dependent haemolysis. Haemoglobin is released during haemolysis, and free haemoglobin (frHb) causes tubular cell injury after exceeding the binding capacity of haptoglobin (Hp). The objective of this study was to investigate the influence of perioperative changes in frHb and Hp levels on the incidence of CS-associated (CSA) AKI. After receiving local ethics committee approval and obtaining informed consent from our patients, we analysed the data pertaining to 154 patients undergoing CPB surgery...

OBJECTIVE: To investigate how atrophy is distributed over the cross section of the upper cervical spinal cord and how this relates to functional impairment in multiple sclerosis (MS). METHODS: We analysed the structural brain MRI scans of 54 patients with relapsing-remitting MS (n=22), primary progressive MS (n=9), secondary progressive MS (n=23) and 23 age- and sex-matched healthy controls. We measured the cross-sectional area (CSA), left-right width (LRW) and anterior-posterior width (APW) of the spinal cord at the segmental level C2...

This study employed the ultrasonic spray-freeze-drying technique to prepare porous mannitol carriers that incorporated hydrophobic cyclosporine A (CsA) nanoparticles (NPs) for pulmonary delivery. Two nanosuspension stabilization systems, (1) a combination of lecithin and lactose system and (2) a D-α-tocopheryl polyethylene glycol succinate (TPGS) system, were investigated. The ability of the lecithin and TPGS in anchoring the hydrophobic CsA NPs to the porous hydrophilic mannitol structure was first reported...
