BACKGROUND: Stroke involving the cerebral white matter (WM) has increased in prevalence, but most experimental studies have focused on ischemic injury of the gray matter. This study was performed to investigate the WM in a unique rat model of photothrombotic infarct targeting the posterior limb of internal capsule (PLIC), focusing on the identification of the most vulnerable structure in WM by ischemic injury, subsequent glial reaction to the injury, and the fundamental histopathologic feature causing different neurologic outcomes...

OBJECTIVE: To explore potential spreading to peripheral nerves of the mitochondrial dysfunction in chronic progressive external ophthalmoplegia (CPEO) by assessing axonal excitability. METHODS: CPEO patients (n=13) with large size deletion of mitochondrial DNA and matching healthy controls (n=22) were included in a case-control study. Muscle strength was quantified using MRC sum-score and used to define two groups of patients: CPEO-weak and CPEO-normal (normal strength)...

Gray leaf spot (GLS), caused by the sibling species Cercospora zeina or Cercospora zeae-maydis, is cited as one of the most important diseases threatening global maize production. C. zeina fails to produce cercosporin in vitro, and in most cases causes large coalescing lesions during maize infection; a symptom generally absent from cercosporin-deficient mutants in other Cercospora spp. Here we describe the C. zeina cercosporin toxin biosynthetic gene cluster. The oxidoreductase gene CTB7 contained several insertions and deletions as compared to the C...

The exfoliation of gray arsenic into single- or few-layered arsenene is a challenge of utmost importance. We propose here that the conformational change in the photo-isomerization of azobenzene-based photochromes might be used to promote the exfoliation of multilayered arsenene. Our density functional theory calculations show that the trans-to-cis conformational change can lead to an increase of the adjacent interlayer distance of arsenene from 6.59 Å to 11.07 Å. Starting from the transition state, the azobenzene molecule can be isomerized into the more stable trans form based on further ab initio molecular dynamics simulations...

BACKGROUND: Sarcoidosis and tuberculosis (TB) share epidemiological, immunological, and molecular features common to both, and often, it becomes difficult to differentiate them especially in a highly TB-endemic country like India. We report a case of optic disc granuloma along with epididymitis and infertility in a male who showed a response to treatment with anti-tuberculosis therapy and steroids. RESULTS: A 35-year-old Indian male who presented with complaints of blurring vision in the right eye for 6 months and treated elsewhere with two intravitreal injections of anti-VEGF was found to have optic disc granuloma in the right eye...

REVIEW
Stephen A Back
The human preterm brain is particularly susceptible to cerebral white matter injury (WMI) that disrupts the normal progression of developmental myelination. Advances in the care of preterm infants have resulted in a sustained reduction in the severity of WMI that has shifted from more severe focal necrotic lesions to milder diffuse WMI. Nevertheless, WMI remains a global health problem and the most common cause of chronic neurological morbidity from cerebral palsy and diverse neurobehavioral disabilities. Diffuse WMI involves maturation-dependent vulnerability of the oligodendrocyte (OL) lineage with selective degeneration of late oligodendrocyte progenitors (preOLs) triggered by oxidative stress and other insults...

BACKGROUND: Three-weekly high-dose cisplatin (100 mg/m(2)) is considered the standard systemic regimen given concurrently with postoperative or definitive radiotherapy in locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). However, due to unsatisfactory patient tolerance, various weekly low-dose schedules have been increasingly used in clinical practice. The aim of this meta-analysis was to compare the efficacy, safety, and compliance between these two approaches...

BACKGROUND: Osteoarthritis (OA) of the hip is a disease that entails a major burden for patients and the society as a whole. One way of measuring this burden for the patient is through impact on Health-related Quality of Life (HRQL). The Oxford Hip Score (OHS) is a well-known tool to measure HRQL in patients with OA of the hip. This study aims to assess the psychometric properties of the Spanish-adapted version of the OHS, including its reliability, validity, and sensitivity to change...

Preclinical evidence in support of the potential utility of mGlu5 NAMs for the treatment of a variety of psychiatric and neurodegenerative disorders is extensive, and multiple such molecules have entered clinical trials. Despite some promising results from clinical studies, no small molecule mGlu5 NAM has yet to reach market. Here we present the discovery and evaluation of N-(5-fluoropyridin-2-yl)-6-methyl-4-(pyrimidin-5-yloxy)picolinamide (27, VU0424238), a compound selected for clinical evaluation. Compound 27 is more than 900-fold selective for mGlu5 versus the other mGlu receptors, and binding studies established a Ki value of 4...

Hepatoid adenocarcinoma (HAC) is a rare tumor that typically originates in gastrointestinal tissue, such as the stomach, but can also occasionally originate in the lung. The majority of HACs express α-fetoprotein (AFP) on tumor cells, and serum AFP can be used as a marker of response to treatment or disease progression. HAC has a poor prognosis, although early diagnosis and aggressive treatment can result in long-term survival. To the best of our knowledge, this is the first reported case of HAC metastasizing to the tonsil...

REVIEW
Dionysia Kelgiorgi, Christos Dervenis
Pancreatic neuroendocrine tumors (PanNETs) manifest with a range of symptoms and pose a therapeutic challenge. A team approach, in which many specialists come together, is necessary in the quest for the best patient-tailored treatment. Disciplines such as oncology, surgery, basic science, endocrinology, radiology, and nuclear medicine need to work side by side, equally contributing to patient care and to advancing our better understanding of this fascinating disease.

Stuart Anstis
A patch that alternates between two hues such as dark green and light blue looks greenish on a light gray surround and bluish on a dark gray surround ("flicker-augmented contrast"). Thus, when an edge alternates between two hues in the same location, the visual system selects the more salient hue-the one with the higher Michelson contrast. However, the afterimage is the same pink, driven by the time integral of the physical, not the perceptual, adapting hues and regardless of the surround luminance. So the process of edge biasing does not transfer to the mechanism that creates afterimages...

Current treatment options for spinal cord injury (SCI) are scarce. One of the most promising innovative approaches include gene-therapy, however no single gene has so far been shown to be of clinical relevance. This study investigates the efficacy of various combinations of vascular endothelial growth factor (VEGF), glial cell-derived neurotrophic factor (GDNF), angiogenin (ANG) and neuronal cell adhesion molecule (NCAM) in rats. Multiple therapeutic genes were administered intrathecally either via adenoviral vectors or by using genetically modified human umbilical cord blood mononuclear cells (hUCBMCs)...

Arterial spin labeling (ASL) is the primary non-invasive MRI approach to measure baseline cerebral blood flow (CBF) in healthy subjects and patients. ASL also allows concurrent functional BOLD signal and CBF measurements, but the latter typically suffers from low contrast-to-noise (CNR) ratio. Ultra-high-field imaging significantly boosts BOLD signal CNR. However, it is contested whether also CBF CNR benefits from increasing magnetic field strength, especially given that technical challenges related to field inhomogeneities and power deposition constraints exist...
