Crossed cheiro-oral syndrome (CCOS) is characterized by crossed sensory disturbance confined to the unilateral perioral area and contralateral hand/finger(s). Although a few classical crossed sensory syndromes accurately predict brainstem or spinal involvement, the clinical significance of CCOS remains unclear. In this study, we analyzed the etiology, localization and outcome of CCOS patients. The results showed that ischemic stroke is the exclusive cause of CCOS. The location of responsible stroke is pertinent to the middle or upper level of the lateral medulla oblongata medial to the lateral sulcus...

BACKGROUND: Being overweight during childhood and adolescence is associated with increased risk of cardiovascular disease in adulthood, but the relative contribution of prepubertal childhood BMI and BMI change during puberty to adult mortality due to cardiovascular disease is unknown. We assessed the contribution of these two distinct developmental BMI parameters for cardiovascular mortality in adult men. METHODS: As a part of the ongoing population-based BMI Epidemiology Study (BEST) in Gothenburg, Sweden, men born between 1945 and 1961 with information on both their childhood BMI at age 8 years and BMI change during puberty were included in the study and followed up until December, 2013...

Selective targeting of the PML/RARα oncoprotein demonstrates a successful molecular targeted therapy in acute promyelocytic leukemia (APL) with a typical t(15:17) chromosomal translocation. The zinc-thiolate coordination is critical for structural stability of zinc finger proteins, including the PML moiety of PML/RARα. Based on the known interaction of redox-active selenium compounds with thiolate ligands of zinc, we herein have investigated the abrogatory effects of selenite alone or in combination with all-trans retinoic acid on PML/RARα and the possible effects on differentiation in these cells...

We have grown GaAsP nanowires with high optical and structural quality by Aerotaxy, a new continuous gas phase mass production process to grow III-V semiconductor based nanowires. By varying the PH3/AsH3 ratio and growth temperature, size selected GaAs1-xPx nanowires (80 nm diameter) with pure zinc-blende structure and with direct band gap energies ranging from 1.42 to 1.90 eV (at 300 K), (i.e., 0 ≤ x ≤ 0.43) were grown, which is the energy range needed for creating tandem III-V solar cells on silicon. The phosphorus content in the NWs is shown to be controlled by both growth temperature and input gas phase ratio...

BACKGROUND: The effect of alteplase on patient survival after ischaemic stroke is the subject of debate. We report the effect of intravenous alteplase on long-term survival after ischaemic stroke of participants in the Third International Stroke Trial (IST-3). METHODS: In IST-3, done at 156 hospitals in 12 countries (Australia, Europe, and the UK), participants (aged >18 years) were randomly assigned with a telephone voice-activated or web-based system in a 1:1 ratio to treatment with intravenous 0·9 mg/kg alteplase plus standard care or standard care alone within 6 h of ischaemic stroke...

BACKGROUND: In 1946, Opalski reported two cases of Wallenberg syndrome with ipsilateral hemiparesis (IH). His hypothesis seems to be based on the view that IH is caused by post-decussating pyramidal tract damage. Afterwards, other researchers proposed a different hypothesis that ipsilateral sensory symptoms of limbs (ISSL) or ipsilateral limb ataxia (ILA) caused by lateral medullary infarction (LMI) might lead to ipsilateral motor weakness. The present study is aimed to clarify whether IH in LMI patients is attributable mainly to ISSL/ILA or disruption of ipsilateral post-decussating pyramidal tract...

BACKGROUND: Alzheimer's disease biomarkers are important for early diagnosis in routine clinical practice and research. Three core CSF biomarkers for the diagnosis of Alzheimer's disease (Aβ42, T-tau, and P-tau) have been assessed in numerous studies, and several other Alzheimer's disease markers are emerging in the literature. However, there have been no comprehensive meta-analyses of their diagnostic performance. We systematically reviewed the literature for 15 biomarkers in both CSF and blood to assess which of these were most altered in Alzheimer's disease...

Babinski-Nageotte Syndrome (BNS) is one of the brainstem syndromes characterized by muscle weakness in the opposite half of the body with classic Wallenberg findings. According to our literature survey, only a few cases have been reported and none of them was in the postpartum period. We report a case of a typical BNS in a postpartum woman with an ischemic lesion in the medulla oblongata shown on magnetic resonance imaging.

A 60-year-old man was admitted to our hospital because of vertigo and repeated vomiting, which suddenly occurred 25 hours before admission. Neurologic examination revealed Wallenberg syndrome on the left side, and brain MRI showed acute infarcts in the left lateral medulla as well as in the left internal carotid artery (ICA) territory. MR angiography did not depict the left vertebral artery (VA) and the left ICA. Despite antithrombotic treatment, he developed bulbar palsy, and then, brain herniation due to infarct growth in the left middle cerebral artery territory...

We have imaged GaP nanowires (NWs) incubated with human laminin, serum albumin (HSA), and blood plasma using both cryo-transmission electron microscopy and synchrotron based X-ray photoemission electron microscopy. This extensive imaging methodology simultaneously reveals structural, chemical and morphological details of individual nanowires and the adsorbed proteins. We found that the proteins bind to NWs, forming coronas with thicknesses close to the proteins' hydrodynamic diameters. We could directly image how laminin is extending from the NWs, maximizing the number of proteins bound to the NWs...

We recently experienced 2 young adult patients who developed ischemic stroke after regular intravenous immunoglobulin (IVIg) therapy for agammaglobulinemia with diagnosis of common variable immunodeficiency (CVID) in their childhood. Patient 1 was 26-year-old woman, who developed Wallenberg's syndrome 6 days after the last IVIg therapy, but had no further stroke recurrence with cilostazol later. Patient 2 was 37-year-old man, who developed recurrent cerebral infarction in the territory of bilateral lenticulostriate branches like branch atheromatous disease (BAD) several days after the IVIg therapy...

The assessment of acute vertigo in childhood is often challenging, but fortunately a central cause is rarely identified. We present the case of a 7-year-old boy who developed, after a mild head trauma, a rotary vertigo associated with nausea and vomiting. A posttraumatic peripheral vestibular dysfunction was first suspected but not confirmed by an otoneurological evaluation. When subtle neurological signs were elicited, a brain magnetic resonance imaging was promptly requested. This showed a small infarct on the lateral posterior left part of the medulla oblongata of the brainstem, typical of Wallenberg syndrome...

III-V Nanowires (NWs) grown with metal-organic chemical vapor deposition commonly show a polytypic crystal structure, allowing growth of structures not found in the bulk counterpart. In this paper we studied the radial overgrowth of pure wurtzite (WZ) GaAs nanowires and characterized the samples with high resolution X-ray diffraction (XRD) to reveal the crystal structure of the grown material. In particular, we investigated what happens when adjacent WZ NWs radially merge with each other by analyzing the evolution of XRD peaks for different amounts of radial overgrowth and merging...

Solar energy conversion in photovoltaics or photocatalysis involves light harvesting, or sensitization, of a semiconductor or catalyst as a first step. Rare elements are frequently used for this purpose, but they are obviously not ideal for large-scale implementation. Great efforts have been made to replace the widely used ruthenium with more abundant analogues like iron, but without much success due to the very short-lived excited states of the resulting iron complexes. Here, we describe the development of an iron-nitrogen-heterocyclic-carbene sensitizer with an excited-state lifetime that is nearly a thousand-fold longer than that of traditional iron polypyridyl complexes...

Ternary nanowires (NWs) often exhibit varying material composition along the NW growth axis because of different diffusion properties of the precursor molecules. This constitutes a problem for optoelectronic devices for which a homogeneous material composition is most often of importance. Especially, ternary GaInP NWs grown under a constant Ga-In precursor ratio typically show inhomogeneous material composition along the length of the NW due to the complexity of low temperature precursor pyrolysis and relative rates of growth species from gas phase diffusion and surface diffusion that contribute to synthesis of particle-assisted growth...

BACKGROUND: Various sensory impairments have been reported in patients with lateral medullary syndrome, also known as Wallenberg syndrome. The typical sensory impairments experienced by patients with this condition are ipsilateral facial and contralateral trunk and limb thermal hypesthesia and hypoalgesia. Tactile (light touch) sensation is not generally diminished. Here we report the case of a 35-year-old man with lateral medullary infarction who had atypical sensory impairment. METHODS: We examined the results from the neurological examination of the patient as well as findings from computed tomography of the head and magnetic resonance imaging...

It is presented the results of survey and treatment of 32 patients with upper esophageal sphincter achalasia. In 29 of them achalasia was consequence of stroke in brain stem (Zakharchenko-Wallenberg syndrome). 28 patients were operated using P. Chodoch method in 7 cases and author's technique of myotomy with pharyngoesophageal junction plasty in 21 patients. Plastic myotomy gives excellent and good results in 81% of observations due to preservation of innervation of muscles providing function of epiglottis and pharyngeal constrictors...
