Paratype: 1♂, same data as holotype (CAFM). Description. Male. Forewing length 12.0–13.0 mm (Fig. 6). Antenna shortly unipectinate. Ground color ochre. Forewings with pattern typical of the genus. Hindwings dark greyish brown, with lighter fringe and bright yellow dorsal margin. Abdomen. Male sternite VIII has a pair of digitiform processes, slightly pointed, with tips bending outwards. Genitalia. Uncus with lateral expansions (uncus looks like trifid) and apical spur (Fig. 20). Gnathos with two narrow long lateral processes curved at right angle apically, with the left one bearing a weak papilla-shaped medial process (Fig. 20, this process is shown by arrow). Valvae elongated, without well-defined sacculus and lacking saccular processes. Juxta flattened, with apical notch. Aedeagus slightly spiraled, narrow and with a strongly sclerotized apical spur. Female. Unknown. Diagnosis. The species is similar to its congeners with the exception of Sansarea formosana Solovyev, 2017 known from Taiwan, which is much darker in coloration. The new species differs from its congeners (Figs 21–24) by the gnathos showing two strong lateral lobes curved apically at right angle, with the left one bearing a weak papilla-shaped medial process, and by the processes of sternite VIII digitiform, slightly pointed, and with tips bending outwards. The male genitalia are mostly similar to those of Sansarea grata Solovyev & Witt, 2009 (Fig. 22) and S. zeta Solovyev & Witt, 2009 (Fig. 23). However, in S. alenae sp. nov., the long lateral processes of the gnathos are curved at a right angle apically, the apical processes of the gnathos are at least 2/3 the length of the lateral ones, and the processes of sternite VIII are more separated and smaller, with the length not exceeded a half distance between these processes. Distribution. China (Yunnan). Phenology and habitat. Two males were collected at ultraviolet light in middle May at an altitude of approximately 1,800 m asl in primary mountains mixed forest, dominated by various deciduous trees, bamboo and shrubs (Figs 34, 35).

This species is well separated from its only congener, Euphlyctina phaeopasta (Hampson, 1906) (Fig. 9) by the forewings with a white large subapical mark, a large white discal spot and a black apical comma-like mark. The male genitalia are also diagnostic: the juxta bears two pointed and slender lateral processes, approximately equal in length, and medially enlarged; whereas these processes are broad, unequal in length, crescent-shaped, and without the enlarged medial part in E. phaeopasta (Fig. 19). The saccular processes of valva are located more distally in E. phaeopasta with a distance from the valvar apex equal in length to the saccular process, while in E. butvilai sp. nov. this distance is equal to 1.5 the length of the saccular process. Distribution. China (Zhejiang, Yunnan). Phenology and habitat. The holotype specimen was collected on the 18th of June, whilst the paratype was collected at ultraviolet light in mid May. The new species was collected at an altitude of approximately 1,800 m asl in primary mountains mixed forest, dominated by various deciduous trees, bamboo and shrubs (Figs 34, 35). Etymology. The new species is named after our colleague and prominent Lithuanian collector Rimantas Butvila (Joniškis, Lithuania). Remarks. The male from Yunnan designated as paratype has minor differences compared to the holotype, including shape of the forewings and coloration, however, at this stage, these differences are regarded as intraspecific variations.Published as part of Solovyev, Alexey V. & Saldaitis, Aidas, 2021, Five new species of Limacodidae (Lepidoptera: Zygaenoidea) from South-East Asia, pp. 101-116 in Zootaxa 4999 (2) on page 104, DOI: 10.11646/zootaxa.4999.2.1, http://zenodo.org/record/508939
Redox speciation of iron, manganese, and copper in cerebrospinal fluid by strong cation exchange chromatography – sector field inductively coupled plasma mass spectrometry
No full textAbstract
A new method of simultaneous redox speciation of iron (II/III), manganese (II/III), and copper (I/II) in cerebrospinal fluid (CSF) has been designed. For the separation of redox species strong cation exchange chromatography (SCX) with isocratic elution was employed. Species were detected using inductively coupled plasma sector field mass spectrometry (ICP-sf-MS), operating at medium resolution. The following parameters were optimized: analytical column, eluent composition and pH, CSF injection volume and dilution factor. Analytical column Dionex IonPac CS5A RFIC 4*250 mm was found to retain and separate species of interest the most effectively under the isocratic elution with a buffer, containing 50 mM ammonium citrate, 7.0 mM pyridine-2,6-dicarboxylic acid at pH = 4.2 and flow rate of 0.8 L min−1. Injection volume of 50 μL with CSF sample dilution of 1/3 (v/v) with the eluent was shown to result in minimal matrix suppression. For species identification, retention time matching with standards was used. The stability of metalloproteins (ferritin, transferrin, and ceruloplasmin) under elution conditions was evaluated. For the quantification of redox species, external calibration was employed. To avoid column contamination, a blank was run after measurement and all quantification values were blank subtracted. For recovery checks, species quantification data was verified against total content of an element, measured by dynamic reaction cell ICP-MS. Recoveries (sum of quantified species vs. total element determinations) were 82.5 ± 22% (Mn), 92 ± 11% (Fe), and 88.7 ± 12% (Cu). The method was tested using 38 real CSF samples. Limits of detection (3σ) for the CSF samples were 0.5 μg L−1, 0.6 μg L−1, and 0.8 μg L−1 for Fe, Mn, and Cu species, respectively. Retention time precision was 1–7.5% (as RSD), whereas peak area RSDs were in the range 5–11%, both depending on the species

The study of levels from redox-active elements in cerebrospinal fluid of amyotrophic lateral sclerosis patients carrying disease-related gene mutations shows potential copper dyshomeostasis.
No full textAmyotrophic lateral sclerosis is a progressive neurodegenerative disease characterized by a loss of function of motor neurons. The etiology of this disorder is still largely unknown. Gene-environment interaction arises as a possible key factor in the development of amyotrophic lateral sclerosis. We assessed the levels of trace metals, copper (Cu), iron (Fe), and manganese (Mn), of 9 amyotrophic lateral sclerosis cases and 40 controls by measuring their content in cerebrospinal fluid. The following trace element species were quantified using ion chromatography-inductively coupled plasma mass spectrometry: univalent copper (Cu-I), divalent Cu (Cu-II), divalent Fe (Fe-II), trivalent Fe (Fe-III), divalent Mn (Mn-II), trivalent Mn (Mn-III), and also unidentified Mn species (Mn-unknown) were present in some samples. When computing the relative risks for amyotrophic lateral sclerosis through an unconditional logistic regression model, we observed a weak and imprecise positive association for iron (Fe III, adjusted odds ratio 1.48, 95% CI 0.46-4.76) and manganese (total-Mn and Mn-II; adjusted odds ratio 1.11, 95% CI 0.74-1.67, and 1.13, 95% CI 0.79-1.61, respectively). Increased risk for copper was found both in the crude analysis (odds ratio 1.14, 95% CI 0.99-1.31) and in multivariable analysis after adjusting for sex, age, and year of storage (1.09, 95% CI 0.90-1.32). Our results suggest a possible positive association between Cu and genetic amyotrophic lateral sclerosis, while they give little indication of involvement of Fe and Mn in disease, though some correlations found also for these elements deserve further investigation
Elevated Levels of Selenium Species in Cerebrospinal Fluid of Amyotrophic Lateral Sclerosis Patients with Disease-Associated Gene Mutations
No full textBACKGROUND:
Although an increasing role of genetic susceptibility has been recognized, the role of environmental risk factors in amyotrophic lateral sclerosis (ALS) etiology is largely uncertain; among neurotoxic chemicals, epidemiological and biological plausibility has been provided for pesticides, the heavy metal lead, the metalloid selenium, and other persistent organic pollutants. Selenium involvement in ALS has been suggested on the basis of epidemiological studies, in vitro investigations, and veterinary studies in which selenium induced a selective toxicity against motor neurons.
OBJECTIVE:
Hypothesizing a multistep pathogenic mechanism (genetic susceptibility and environmental exposure), we aimed to study selenium species in ALS patients carrying disease-associated gene mutations as compared to a series of hospital controls.
METHODS:
Using advanced analytical techniques, we determined selenium species in cerebrospinal fluid sampled at diagnosis in 9 ALS patients carrying different gene mutations (C9ORF72, SOD1, FUS, TARDBP, ATXN2, and TUBA4A) compared to 42 controls.
RESULTS:
In a patient with the tubulin-related TUBA4A mutation, we found highly elevated levels (in μg/L) of glutathione-peroxidase-bound selenium (32.8 vs. 1.0) as well as increased levels of selenoprotein-P-bound selenium (2.4 vs. 0.8), selenite (1.8 vs. 0.1), and selenate (0.9 vs. 0.1). In the remaining ALS patients, we detected elevated selenomethionine-bound selenium levels (0.38 vs. 0.06).
CONCLUSIONS:
Selenium compounds can impair tubulin synthesis and the cytoskeleton structure, as do tubulin-related gene mutations. The elevated selenium species levels in the TUBA4A patient may have a genetic etiology and/or represent a pathogenic pathway through which this mutation favors disease onset, though unmeasured confounding cannot be excluded. The elevated selenomethionine levels in the other patients are also of interest due to the toxicity of this nonphysiological selenium species. Our study is the first to assess selenium exposure in genetic ALS, suggesting an interaction between this environmental factor and genetics in triggering disease onset
