PREMISE In the complex soil nutrient environments of wild populations of annual plants, in general, low nutrient availability restricts growth and alters root-shoot relationships. However, our knowledge of natural selection on roots in field settings is limited. We sought to determine whether selection acts directly on root traits and to identify which components of the soil environment were potential agents of selection. METHODS We studied wild native populations of Arabidopsis thaliana across 4 years, measuring aboveground and belowground traits and analyzing soil nutrients. Using multivariate methods, we examined patterns of natural selection and identified soil attributes that contributed to whole-plant form. In a common garden experiment at two field sites with contrasting soil texture, we examined patterns of selection on root and shoot traits. RESULTS In wild populations, we uncovered selection for above- and belowground size and architectural traits. We detected variation through time and identified soil components that influenced fruit production. In the garden experiment, we detected a distinct positive selection for total root length at the site with greater water-holding capacity and negative selection for measures of root architecture at the field site with reduced nutrient availability and water holding capacity. CONCLUSIONS Patterns of natural selection on belowground traits varied through time, across field sites and experimental gardens. Simultaneous investigations of above- and belowground traits reveal trait functional relationships on which natural selection can act, highlighting the influence of edaphic features on evolutionary processes in wild annual plant populations. © 2020 Botanical Society of America.A 77-year-old woman with a history of hypertension developed acute onset of aphasia and right hemiplegia and hemisensory loss. She was urgently referred to emergency department. Cerebral multidetector computed tomographic angiography (MD-CTA) revealed an acute ischemic stroke due to the occlusion of the left middle cerebral artery (Figure 1). Since the symptoms started three hours previously, the patient was candidate for mechanical thrombectomy. The patient then performed a selective digital subtraction angiography (DSA) of the left internal carotid artery that confirmed occlusion of the ipsilateral middle cerebral artery (Figure 2) and subsequently successfully performed the endovascular mechanical thrombectomy (Figure 2). Her clinical course has shown neurological symptoms improvement over time. Acute ischemic stroke can be caused by several factors, but the main ones are arterial and cardiac embolism, arterial wall disease or variants(1-4). The National Institutes of Health Stroke Scale (NIHSS) score, is widely used as clinical assessment for neurological deficits related to ischemic stroke(1). MDCTA and Magnetic Resonance Imaging are the two gold standard methods for diagnosis in acute ischemic stroke patients(1-5). Thrombolytic therapy of this pathological state began in the fifties, while the endovascular mechanical thrombectomy was defined as a new standard of care in 2015(1,5,6). This recent technique have added tissue window" to the existing "time window" (5,6). So, nowadays patients with small ischemic core, large penumbra, and good collaterals vessel may benefit from endovascular mechanical thrombectomy(1,5,6); even if they arrive within 6-24 h of stroke onset(5.PURPOSE Sporadic hemiplegic migraine (SHM) is characterized by a prolonged motor aura that accompanies a migraine attack, and its underlying pathophysiology remains unclear. #link# Functional image during the event can help to explore the mechanism. CASE REPORT We report a finding of 18-fluorodeoxyglucose positron emission tomography (FDG-PET) in a 15-year-old female with SHM. She presented with recurrent right arm weakness and pain with migrainous headache. A video electroencephalogram showed no evidence of epilepsy during the events. Subtraction of ictal-interictal FDG-PET coregistered to magnetic resonance imaging was performed for the image analysis. In comparison with the interictal state, the FDG-PET image showed decreased glucose metabolism in the bilateral dorsal lateral frontal cortices and bilateral occipital cortices, whereas increased metabolism in the left precentral motor cortex and right premotor cortex. CONCLUSION These findings reveal an increase in metabolism in the motor cortex during general cortical dysfunction in the frontal and occipital cortices in SHM. Key words FDG-PET, hemiplegic migraine, migraine, positron emission tomography, SISCOM.Carotid-cavernous fistulae (CCFs) are classified into the direct and indirect types, which can be attributed to trauma, atherosclerosis, hypertension, diabetes mellitus, pregnant or postmenopausal status(1). Cerebral angiography is the gold standard for the diagnosis of CCFs. Doppler ultrasound, which typically reveals increased blood flow velocity and decreased resistance index (RI) in the feeding arteries, can assist in the diagnosis(2-3). We herein report a case of indirect CCF presenting with high RI in the feeding arteries, which is mainly attributed to the generalized atherosclerotic change, and is regarded as a diagnostic pitfall of the CCFs.OBJECTIVE Various numbers of factors such as oxidative stress, neurotoxins, and pesticides have been implicated in its pathophysiology of Parkinson's disease (PD). Paraoxonas1 (PON1) metabolizes xenobiotics, including pesticides. Therefore, we surveyed the relationship between PON1 polymorphisms with its activities in the pathogenesis of Parkinson's disease.. METHODS We investigated polymorphisms of the PON1 (L55M and Q192R) by PCR-RFLP assays; we also measure the levels of PON1, TAC (total antioxidant capacity) and TOS (total oxidant status) with ELISA (Enzyme-linked immunosorbent assay) and spectrophotometric method for their activities. selleck chemical and arylesterase activity of PON1 as well as their concentrations were lower in patients with PD compared with control group, but from the view of the specific activity, it was not significant between two groups. In the compare of TAC, TOS, and OSI, the TOS and OSI were higher in the patients than controls, while patients had lower levels of TAC compared with controls.
