Spinal extradural arachnoid cyst (SEAC) is a rare cause of spinal cord compression. Bifocal location of thoracic and sacral SEACs is rarely reported in the literature. We report a case of thoracic spinal cord compression by SEAC associated with asymptomatic multiple sacral Tarlov cysts (TC). The surgical management and postoperative outcome of the patient are discussed. A 34-year-old woman was referred to the hospital for acute thoracic pain with a history of chronic long-standing back pain. She complained of walking difficulties...

KRAS is the most common oncogenic driver in lung adenocarcinoma (LUAC). We previously reported that STK11/LKB1 (KL) or TP53 (KP) co-mutations define distinct subgroups of KRAS-mutant LUAC. Here, we examine the efficacy of PD-1 inhibitors in these subgroups. Objective response rates to PD-1 blockade differed significantly among KL (7.4%), KP (35.7%), and K-only (28.6%) subgroups (P<0.001) in the SU2C cohort (174 patients) with KRAS-mutant LUAC and in patients treated with nivolumab in the CheckMate-057 phase 3 trial (0% vs 57...

Migrating birds have been implicated in pathogen dissemination over long-distances. The lack of data on birds' intestinal microbiota makes these animals a promising path to understand their potential role in the transmission of antibiotic resistant bacteria. This work aims to study the diversity of enterococci species and to analyze the antimicrobial resistant phenotypes/genotypes, as well as the genetic lineages of isolates obtained from faecal and pellet samples of colonial wild birds in Tunisia. Seventy-nine enterococci were recovered of 150 wild bird, after inoculation of samples in Slanetz-Bartley agar, and were identified as E...

Background: Pasteurella multocida continues to pose a danger to prone farm and wild animals all over the world. Chemotherapeutic treatments are progressively losing their effectiveness, last for long time, and cost a lot of money, as well as being toxic to human consumers. Therefore, clearing the way for immunization as a big-wheel alternative against the economic grain. Yet, the vaccines available in the market do not confer the necessary protection against the pathogen. The integration of the well adjuvanted killed vaccine with the attenuated vaccines proved to offer an effective protection to the host animals...

OBJECTIVES: Vocal fold nodules (VFNs) are benign disorders affecting the superficial lamina propria of the true vocal folds. The etiology of VFNs still remains unclear but laryngeal trauma caused by vocal abuse, tobacco, alcohol, and laryngopharyngeal reflux (LPR) plays a crucial role on the pathogenesis. The aim of this study was to assess the presence of pepsin in formalin-fixed, paraffin-embedded (FEPE) specimens of VFNs to evaluate the role of LPR as a risk factor for VFNs. MATERIALS AND METHODS: A total of 28 pathology specimens of patients suffering from VFNs who had undergone laser microsurgery under general anesthesia were evaluated...

This study was designed to compare the complete blood count values of opioid users (N = 61) and healthy subjects (N = 61), particularly monocyte-to-lymphocyte ratio (MLR) and platelet-to-lymphocyte ratio (PLR). PLR, MLR, and percentage of monocyte (MONO%) were significantly lower in opioid use disorder (OUD) group (P = 0.012, P = 0.005, P = 0.000). The area under the ROC curve of MLR and PLR levels for OUD was 0.349 and 0.368. MONO% correlated with substance use duration. Measurements like lymphocyte-related ratios and MONO% in opioid use can be important in substance monitoring, detection, and differentiation of acute and chronic conditions...

There are some disparities between pharmacological and toxicological xenobiotic receptor (xenosensors) pathways. These variations include receptor models that indicate several toxic patterns. Such models have demanded some update from traditional medical receptor relations studied by pharmacologists. These may include the response time, the molecular level, and unclear directions of toxicological metabolism. Xenosensors activities were affected by many factors that include genetic elements, physiological status, xenobiotic complication, and species-specific variations...

A low-cost and reliable cooling/heating-assisted microextraction (CHaME) instrument was designed and fabricated for use in different modes of microextraction methods. The CHaME setup is able to cool down the sorbent and simultaneously heat the sample in a wide temperature range. Consequently, it can create a large thermal gap between the sorbent and the sample matrix, to promote the release of analytes from the sample tissue and enhance their effective trapping on the microextraction phase. The primary versions of the instrument have previously been evaluated, coupled with different modes of solid- and liquid-phase microextraction strategies...

Fluoxetine, a commonly prescribed antidepressant, use in nociceptive pain management represent one of the unsettled issues of fluoxetine therapeutics. By reviewing the literature about fluoxetine's possible roles in this setting; those could be solitary antinociceptive effect, enhancement of acute morphine analgesia, blocking morphine tolerance development, and blocking dependence development and associated abstinence syndrome. In this study, we examined those four alleged roles of fluoxetine. Moreover, since effective alleviation of morphine tolerance, dependence, and abstinence syndrome represents one of the most challenging medical needs, we biochemically analyzed fluoxetine effect on these phenomena...

BACKGROUND: Nano-PCR is a recent tool that is used in viral diseases diagnosis. The technique depends on the fundamental effects of gold nanoparticles (AuNPs) and is considered a very effective and sensitive tool in the diagnosis of different diseases including viral diseases. Although several techniques are currently available to diagnose foot and mouth disease virus (FMDV), a highly sensitive, highly specific technique is needed for specific diagnosis of the disease. In the present work, a novel AuNPs biosensor has been designed using thiol-linked oligonucleotides that recognize the conserved 3D gene of FMDV...

Hydatid cyst is a helminth infection. The rupture of a hepatic hydatid cyst in inferior vena cava is a rare and lethal complication. Pulmonary embolism is the commonest manifestation. The diagnosis of hydatid cyst is made by histopathological or serological examination, and imaging may suggest the probability of hydatid cyst. Surgical treatment should be performed with caution and always under vascular control. We present two cases of hydatid cyst ruptured into the inferior vena cava. The patients also presented with dyspnea, hemoptysis, and intermittent cough at the time of admission...

Monte Carlo (MC) simulation is widely recognized as an important technique to study the physics of particle interactions in nuclear medicine and radiation therapy. There are different codes dedicated to dosimetry applications and widely used today in research or in clinical application, such as MCNP, EGSnrc and Geant4. However, such codes made the physics easier but the programming remains a tedious task even for physicists familiar with computer programming. In this paper we report the development of a new interface GEANT4 Dose And Radiation Interactions (G4DARI) based on GEANT4 for absorbed dose calculation and for particle tracking in humans, small animals and complex phantoms...
