BACKGROUND: The pterional approach (PA), together with its variants, is still one of the most common methods used by surgeons to reach the anterior and middle cranial base. A highly important technical detail during a PA is the preservation of the frontotemporal branch of the facial nerve, which can be achieved through an interfascial dissection. OBJECTIVE: To describe the anatomy of the interfascial vein (IFV), highlighting its recognition as a significant anatomic reference to perform an interfascial dissection (IFD)...

BACKGROUND: We previously introduced a novel noninvasive technique of intracranial pressure (ICP) monitoring in children with open fontanelles. OBJECTIVE: To compare the ICP obtained by our new technique to the ICP derived from an intradurally implanted ICP measurement device (external ventricular drain, subdural ICP device). METHODS: Children with open fontanelles and need of intracranial monitoring were included in this study. A standard ICP probe was placed upon the frontal fontanelle and data were compared with the values recorded by an already invasively implanted subdural ICP technique...

Antimicrobial resistance (AMR) is now recognized as a global threat to human health. The accessibility of microbial whole-genome sequencing offers an invaluable opportunity for resistance surveillance via the resistome, i.e. the genes and mutations underlying AMR. Unfortunately, AMR prediction from genomic data remains extremely challenging, especially for species with a large pan-genome. One such organism, for which multidrug-resistant (MDR) isolates are frequently encountered in the clinic, is Pseudomonas aeruginosa...

Camptotheca acuminata is 1 of a limited number of species that produce camptothecin, a pentacyclic quinoline alkaloid with anti-cancer activity due to its ability to inhibit DNA topoisomerase. While transcriptome studies have been performed previously with various camptothecin-producing species, no genome sequence for a camptothecin-producing species is available to date. We generated a high-quality de novo genome assembly for C. acuminata representing 403 174 860 bp on 1394 scaffolds with an N50 scaffold size of 1752 kbp...

Background: Cancer-associated fibroblasts (CAFs) are tumor-promoting and correlate with poor survival in many cancers, which has led to their emergence as potential therapeutic targets. However, effective methods to manipulate these cells clinically have yet to be developed. Methods: CAF accumulation and prognostic significance in head and neck cancer (oral, n = 260; oropharyngeal, n = 271), and colorectal cancer (n = 56) was analyzed using immunohistochemistry...

Map-based gene cloning is a vital strategy for the identification of the quantitative trait loci or genes underlying important agronomic traits. The conventional map-based cloning method is powerful but generally time-consuming and labor-intensive. In this context, we introduce an improved bulked segregant analysis method in combination with a virus-induced gene silencing (VIGS) strategy for rapid and reliable gene mapping, identification and functional verification. This method was applied to a multiple recessive marker line of upland cotton, Texas 582 (T582), and identified unique genomic positions harboring mutant loci, showing the reliability and efficacy of this method...

A single low-dose ketamine infusion exhibited a rapid antidepressant effect within 1h. Despite its short biological half-life (approximately 3h), the antidepressant effect of ketamine has been demonstrated to persist for several days. However, changes in brain function responsible for the persistent antidepressant effect of a single low-dose ketamine infusion remain unclear METHODS: Twenty-four patients with treatment-resistant depression (TRD) were randomized into three groups according to the treatment received: 0...

REVIEW
Minhao Hu, David Wattchow, Dayan de Fontgalland
The landscape of surgical anatomy education is progressively changing. Traditional methods, such as cadaveric dissection and didacticism are being increasingly phased out in undergraduate courses for multimodal approaches incorporating problem-based learning, radiology and computer-based simulations. Although effective at clinically contextualizing and integrating anatomical information, these approaches may be a poor substitute for fostering a grasp of foundational 'pure' anatomy. Dissection is ideal for this purpose and hence remains the cornerstone of anatomical education...

This study determined the reproducibility of post-exercise hypotension (PEH) calculated by the following methods: PEH_I=post-exercise BP - pre-exercise BP; PEH_II=post-exercise BP - post-control BP; and PEH_III=[(post-exercise BP - pre-exercise BP)-(post-control BP - pre-control BP)]. Twenty-five participants underwent four sessions divided in two blocks (test and retest). Each block consisted of one exercise and one control session. BP pressure was measured before and after the interventions. The presence of systematic error (paired t-tests), reliability [intraclass coefficient correlation (ICC)], and agreement [typical error (TE) and minimal detectable difference (MDD)] were evaluated...

Running with the ball is a soccer-specific activity frequently used by players during match play and training drills. Nevertheless, the energy cost (EC) of on-grass running with the ball has not yet been determined. The purpose of this study was therefore to assess the EC of constant-speed running with the ball, and to compare it with the EC of normal running. Eight amateur soccer players performed two 6- min runs at 10 km/h on artificial turf, respectively with and without the ball. EC was measured with indirect calorimetry and, furthermore, estimated with a method based on players' accelerations measured with a GPS receiver...

Food contamination due to unintentional leakage of chemicals from food contact materials (FCM) is a source of increasing concern. Since for many of these substances, only limited or no toxicological data are available, the development of alternative methodologies to establish rapidly and cost-efficiently level of safety concern is critical to ensure adequate consumer protection. Computational toxicology methods are considered the most promising solutions to cope with this data gap. In particular, mutagenicity assessment has a particular relevance and is a mandatory requirement for all substances released from plastic FCM, regardless how low migration and exposure are...

Zhe Gong, Theodore Hueckel, Gi-Ra Yi, Stefano Sacanna
Patches on the surfaces of colloidal particles provide directional information that enables the self-assembly of the particles into higher-order structures. Although computational tools can make quantitative predictions and can generate design rules that link the patch motif of a particle to its internal microstructure and to the emergent properties of the self-assembled materials, the experimental realization of model systems of particles with surface patches (or 'patchy' particles) remains a challenge. Synthetic patchy colloidal particles are often poor geometric approximations of the digital building blocks used in simulations and can only rarely be manufactured in sufficiently high yields to be routinely used as experimental model systems...

BACKGROUND/AIMS: In view of the latest findings that matrix metalloproteinase-7 (MMP-7) acted as a vital marker and pathogenic mediator of renal fibrosis in a murine model, we hypothesized that serum MMP-7 level might serve as a noninvasive prognostic biomarker in IgA nephropathy (IgAN) patients. METHODS: We conducted a retrospective follow-up study of 244 IgAN patients for a median of 81.9 months. Serum MMP-7 was detected at the time of diagnosis, and renal progression was assessed by Cox proportional hazards method...

BACKGROUND: Since decades, Forensic Medicine is mainly taught by didactic methods but in last couple of years some other teachinglearning and assessment methods are also introduced at some places which also lacks uniformity. Feedback from learners is most fundamental aspect to assess effectiveness of applied methods, but is not implemented in practice at most medical schools in India. Unfortunately, medical students are deprived of this practical empowerment and thus may not be efficient enough to contribute potentially to the justice system during their professional life...
