The Baltic prawn Palaemon adspersus Rathke, 1837 (Decapoda, Caridea, Palaemonidae): first record, possible establishment, and illustrated key of the subfamily Palaemoninae in northwest Atlantic waters
This study documents the introduction of the European Baltic prawn, Palaemon adspersus Rathke, 1837 to the coastal waters of northeastern North America, specifically the west coast of Newfoundland and the Magdalen Islands in the Gulf of St. Lawrence, Canada. Species identification was verified using morphological and genetic criteria. In September 2011, the first specimens of P. adspersus were collected in Gulf of St. Lawrence waters near Stephenville Crossing, Newfoundland, Canada. In 2012, additional P. adspersus specimens were collected in this area and at St. Andrew’s, located further south in western Newfoundland and in 2013 several egg-bearing females were collected further north in York Harbour. Accidental transport by ballast water of ships seems the likely vector for transport of Baltic prawn to the Gulf of St. Lawrence from Northern Europe or the Caspian Sea. It is possible that this shrimp has a wider presence in Atlantic Canadian waters but, due to its close resemblance to native shrimp species, it may have been previously misidentified, as occurred with specimens collected from the Magdalen Islands. We further expect that other species of the genus Palaemon, including P. elegans Rathke, 1837 from the Baltic Sea or northeastern United States, and P. macrodactylus Rathbun, 1902 from the northeastern United States, may invade the Gulf of St. Lawrence. We provide an illustrated key for the identification of these exotic Palaemon species and to differentiate them from native members of the subfamily Palaemoninae.Funding for this project was provided by the Government of Canada’s Department of Fisheries and Oceans and AGL2011-23689 grant from the Spanish government (Ministerio de Economía y Competitividad).

Bottle aging and storage of wines: a review
Wine is perhaps the most ancient and popular alcoholic beverage worldwide. Winemaking practices involve careful vineyard management alongside controlled alcoholic fermentation and potential aging of the wine in barrels. Afterwards, the wine is placed in bottles and stored or distributed in retail. Yet, it is considered that wine achieves its optimum properties after a certain storage time in the bottle. The main outcome of bottle storage is a decrease of astringency and bitterness, improvement of aroma and a lighter and more stable color. This is due to a series of complex chemical changes of its components revolving around the minimized and controlled passage of oxygen into the bottle. For this matter, antioxidants like sulfur oxide are added to avoid excessive oxidation and consequent degradation of the wine. In the same sense, bottles must be closed with appropriate stoppers and stored in adequate, stable conditions, as the wine may develop unappealing color, aromas and flavors otherwise. In this review, features of bottle aging, relevance of stoppers, involved chemical reactions and storage conditions affecting wine quality will be addressed.The research leading to these results was funded by FEDER under the program Interreg V-A Spain-Portugal (POPTEC) 2014-2020 ref. 0377_IBERPHENOL_6_E and ref. 0181_NANOEATERS_ 01_E; to Xunta de Galicia supporting with the Axudas Conecta Peme the IN852A 2018/58 NeuroFood Project and the program EXCELENCIA-ED431F 2020/12; to Ibero-American Program on Science and Technology (CYTED—AQUA-CIBUS, P317RT0003) and by the Bio Based Industries Joint Undertaking (JU) under grant agreement No 888003 UP4HEALTH Project (H2020-BBIJTI-2019), the JU receives support from the European Union’s Horizon 2020 research and innovation program and the Bio Based Industries Consortium.

Placebo-controlled trial of nimodipine in the treatment of acute ischemic cerebral infarction
Nimodipine is a 1,4-dihydropyridine derivative that shows a preferential
cerebrovascular activity in experimental animals. Clinical data suggest that
nimodipine has a beneficial effect on the neurologic outcome of patients
suffering an acute ischemic stroke. Our double-blind placebo-controlled
multicenter trial was designed to assess the effects of oral nimodipine on the
mortality rate and neurologic outcome of patients with an acute ischemic stroke.
One hundred sixty-four patients were randomly allocated to receive either
nimodipine tablets (30 mg q.i.d.) or identical placebo tablets for 28 days.
Treatment was always started less than or equal to 48 hours after the acute
event. The Mathew Scale, slightly modified by Gelmers et al, was used for
neurologic assessment. Mortality rate and neurologic outcome after 28 days were
used as evaluation criteria. We considered 123 patients to be valid for the
analysis of efficacy. Mortality rates did not differ significantly between
groups. Neurologic outcome after 28 days of therapy did not differ between
groups. However, when only those patients most likely to benefit from any
intervention (Mathew Scale sum score of less than or equal to 65 at baseline)
were analyzed separately in post hoc-defined subgroups, the nimodipine-treated
subgroups showed a significantly better neurologic outcome. This result suggests
that some patients with acute ischemic stroke will benefit from treatment with
nimodipine tablets

Traditional plants from Asteraceae family as potential candidates for functional food industry
Traditional plants have been used in the treatment of disease and pain due to their beneficial properties such as antioxidant, antiinflammation, analgesic, and antibiotic activities. The Asteraceae family is one of the most common groups of plants used in folk medicine. The species Achillea millefolium, Arnica montana, Bellis perennis, Calendula officinalis, Chamaemelum nobile, Eupatorium cannabinum, Helichrysum stoechas, and Taraxacum officinale have been used in different remedies in Northwest Spain. Besides health benefits, some of them like C. nobile and H. stoechas are already employed in cooking and culinary uses, including cocktails, desserts, and savory dishes. This study aimed to review the current information on nutritive and beneficial properties and bioactive compounds of these plants, which are not mainly used as foods but are possible candidates for this purpose. The report highlights their current uses and suitability for the development of new functional food industrial applications. Phenolic compounds, essential oils, and sesquiterpene lactones are some of the most important compounds, being related to different bioactivities. Hence, they could be interesting for the development of new functional foods.The research leading to these results received institutioanl and

Encephalomeningocele cases over 10 years in Thailand: a case series
BACKGROUND: Encephalomeningocele, especially in the frontoethmoidal region, is a form of neural tube defect which affects patients in Southeast Asia more commonly than in Western countries. Its underlying cause is not known but teratogenic environmental agents are suspected. However, nutritional deficiency, as in spina bifida, cannot be excluded. METHODS: This study reports 21 cases of meningocele (without brain tissue in the lesion) and encephalomeningocele (with brain tissue) that were admitted to our hospital for surgical corrections in the period of ten years, from 1990 to 1999. Clinicopathological findings, as well as occupations of family members and prenatal exposures to infectious agents or chemicals were reviewed and analyzed. RESULTS: The most commonly involved area was the frontoethmoidal region, found in 20 cases. The combined pattern between nasoethmoidal and nasoorbital defects was found most frequently (11 from 21 cases) and had more associated abnormalities. Encephalomeningocele had more related abnormalities than meningocele with proportions of 0.6 and 0.3, respectively. CONCLUSIONS: Here, we confirmed that genetic defects are not likely to be the single primary cause of this malformation. However, we could not draw any conclusions on etiologic agents. We suggest that case control studies and further investigation on the role of nutritional deficiencies, especially folic acid, in the pathogenesis of encephalomeningocele are necessary to clarify the underlying mechanisms
Defining Treatment‐Related Adverse Effects in Patients with Glioma: Distinctive Features of Pseudoprogression and Treatment‐Induced Necrosis
Background:
Pseudoprogression (PP) and treatment‐induced brain tissue necrosis (TN) are challenging cancer treatment–related effects. Both phenomena remain insufficiently defined; differentiation from recurrent disease frequently necessitates tissue biopsy. We here characterize distinctive features of PP and TN to facilitate noninvasive diagnosis and clinical management.
Materials and Methods:
Patients with glioma and confirmed PP (defined as appearance 5 months after RT) were retrospectively compared using clinical, radiographic, and histopathological data. Each imaging event/lesion (region of interest [ROI]) diagnosed as PP or TN was longitudinally evaluated by serial imaging.
Results:
We identified 64 cases of mostly (80%) biopsy‐confirmed PP (n = 27) and TN (n = 37), comprising 137 ROIs in total. Median time of onset for PP and TN was 1 and 11 months after RT, respectively. Clinically, PP occurred more frequently during active antineoplastic treatment, necessitated more steroid‐based interventions, and was associated with glioblastoma (81 vs. 40%), fewer IDH1 mutations, and shorter median overall survival. Radiographically, TN lesions often initially manifested periventricularly (n = 22/37; 60%), were more numerous (median, 2 vs. 1 ROIs), and contained fewer malignant elements upon biopsy. By contrast, PP predominantly developed around the tumor resection cavity as a non‐nodular, ring‐like enhancing structure. Both PP and TN lesions almost exclusively developed in the main prior radiation field. Presence of either condition appeared to be associated with above‐average overall survival.
Conclusion:
PP and TN occur in clinically distinct patient populations and exhibit differences in spatial radiographic pattern. Increased familiarity with both conditions and their unique features will improve patient management and may avoid unnecessary surgical procedures.
Implications for Practice:
Pseudoprogression (PP) and treatment‐induced brain tissue necrosis (TN) are challenging treatment‐related effects mimicking tumor progression in patients with brain cancer. Affected patients frequently require surgery to guide management. PP and TN remain arbitrarily defined and insufficiently characterized. Lack of clear diagnostic criteria compromises treatment and may adversely affect outcome interpretation in clinical trials. The present findings in a cohort of patients with glioma with PP/TN suggest that both phenomena exhibit unique clinical and imaging characteristics, manifest in different patient populations, and should be classified as distinct clinical conditions. Increased familiarity with PP and TN key features may guide clinicians toward timely noninvasive diagnosis, circumvent potentially unnecessary surgical procedures, and improve response assessment in neuro‐oncology
Pathologic tearfulness after limbic encephalitis: A novel disorder and its neural basis
Objective We investigated the nature and neural foundations of pathologic tearfulness in a uniquely large cohort of patients who had presented with autoimmune limbic encephalitis (aLE). Methods We recruited 38 patients (26 men, 12 women; median age 63.06 years; interquartile range [IQR] 16.06 years) in the postacute phase of aLE who completed questionnaires probing emotion regulation. All patients underwent structural/functional MRI postacutely, along with 67 age- and sex-matched healthy controls (40 men, 27 women; median age 64.70 years; IQR 19.87 years). We investigated correlations of questionnaire scores with demographic, clinical, neuropsychological, and brain imaging data across patients. We also compared patients diagnosed with pathologic tearfulness and those without, along with healthy controls, on gray matter volume, resting-state functional connectivity, and activity. Results Pathologic tearfulness was reported by 50% of the patients, while no patient reported pathologic laughing. It was not associated with depression, impulsiveness, memory impairment, executive dysfunction in the postacute phase, or amygdalar abnormalities in the acute phase. It correlated with changes in specific emotional brain networks: volume reduction in the right anterior hippocampus, left fusiform gyrus, and cerebellum, abnormal hippocampal resting-state functional connectivity with the posteromedial cortex and right middle frontal gyrus, and abnormal hemodynamic activity in the left fusiform gyrus, right inferior parietal lobule, and ventral pons. Conclusions Pathologic tearfulness is common following aLE, is not a manifestation of other neuropsychiatric features, and reflects abnormalities in networks of emotion regulation beyond the acute hippocampal focus. The condition, which may also be present in other neurologic disorders, provides novel insights into the neural basis of affective control and its dysfunction in disease
Applications of by-products from the olive oil processing: Revalorization strategies based on target molecules and green extraction technologies
During the last decades, olive oil consumption has experienced a continuous increase due to its
unique organoleptic properties and its related beneficial properties. Consequently, waste and by-products
derived from the olive production have also increased causing environmental problems and economic losses.
However, the low-cost and huge availability of these by-products is an opportunity for their valorization and the
obtaining of high added-value compounds such as tyrosol, hydroxytyrosol (HT), oleocanthal, oleuropein (OLE),
ligstroside, squalene, fatty acids, etc. The development of innovative extraction and characterization technologies
is a key factor for the olive sector. In addition, a deeper knowledge about the biological properties of the
compounds present in the recovered products and their mechanism of action is crucial to allow their reintegration
in the food chain and their potential uses in the food and pharmaceutical industries.
Scope and approach: This review encompasses all these aspects showing the advances achieved to date in the olive
oil by-products valorization focusing on their biological properties, including cardioprotective, antioxidant,
anticancer, anti-inflammatory and antidiabetic effects.
Key findings and conclusions: The by-products derived from the Olea europaea L. processing industry are secondary
but valuable products, from which different biologically active molecules can be recovered by green extraction
technologies (PLE, SFE, etc.) and reused for food, pharmaceutical and cosmetic purposes following the circular
economy policies. One of the main advantages on recovering valuable molecules from olive by-products is their
incorporation to functional foods. A direct effect was proved between the use of olive by-products in human
consumption and the heath claims. In this context, different food industries have used the phenolic fraction of
olive by-products, holding mostly HT and OLE, as food additives and as preserving agents due to their antioxidant
properties.The research leading to these results was supported by MICINN
