(Fig. 1) MycoBank: MB 841114 Holotype: IRAN, Khuzestan Province, Ahvaz, isolated from a living leaf of Albizia lebbeck (Fabaceae), Oct. 2018, A. Safi (holotype, IRAN 18081F; ex-type cultures, IRAN 4137C = SCUA-Saf-B10). Etymology. Species epithet refers to the host genus Albizia from which the holotype was isolated. Sexual morph: Hyphae hyaline to pale brown, septate, branched. Ascomata perithecioid, superficial, brown to dark brown in reflected light, globose to subglobose, (79–)118–170(–184) × (71–)100–145(–158) μm, 95 % confidence limits = 134–148.5 × 112.2–124.8 μm, (± SD = 141.3 ± 25.5 × 118.5 ± 22.1 μm, n = 50). Ascomatal wall brown, textura angularis in surface view. Terminal hairs seta-like, septate, unbranched, smooth, brown, tapering towards the tips, 2.5–3.8 μm diam near the base. Lateral hairs similar but more flexuous, narrower and shorter. Asci fasciculate, clavate, spore bearing part (20–)22.5–35(–38.75) × 7.5–16.5 μm, stalks 11.25–22.5 μm long, with 8 irregularly-arranged ascospores, evanescent. Ascospores brown to olivaceous brown, ellipsoidal to ovoid, aseptate, biapiculate, bilaterally flattened, with an apical germ pore, (7.5–)10–11.25(–12.5) × 7.5–10 μm, 95 % confidence limits = 10.4–10.9 × 8.1–8.6 μm, (± SD = 10.7 ± 0.8 × 8.3 ± 0.7 μm, n = 50). Asexual morph: not observed. Culture characteristics—Colonies on OA reaching 60–66 mm after 4 d of incubation at 28 ± 0.5 °C, circular with regular margin, initially white, with age becoming creamy white or slightly pinkish, highly floccose; reverse pinkish white. Colonies on PDA reaching 40–45 mm d after 4 d of incubation at 28 ± 0.5 °C, circular with regular margin, initially pale buff with creamy margin, with age becoming buff with paler margin and sectors, floccose; reverse buff with paler sectors. Additional materials examined. IRAN, Khuzestan Province; Karoon, isolated from a living leaf of A. lebbeck, Sep 2020, A. Safi (SCUA-Saf-B10-2). Notes: In the phylogenetic tree, C. albiziae is closely related to C. cucumericola, but can be distinguished by single nucleotide polymorphism (SNP) analysis of three ITS, tub2 and rpb2 loci (Fig. 2). This new species and the extype strain of C. cucumericola (CBS 378.71) showed 1 bp difference (0.2 %) across 496 nucleotides of the ITS region, 6 bp difference (1.1 %) across 547 nucleotides of the tub2 region, and 5 bp difference (1 %) across 481 nucleotides of the rpb2 region. Chaetomium cucumericola was established by Wang et al. (2016) to accommodate two sterile strains of the genus Chaetomium (CBS 378.71 and CBS 126777), which formed a well-supported clade within phylogenetic group III, including the related species C. olivaceum Cooke & Ellis, C. subglobosum Sergeeva, and C. undulatulum Asgari & Zare. C. albiziae can be distinguished from these three species by smaller ascomata (C. olivaceum: 260–440 × 200–360 μm, C. subglobosum: 300–450 × 265–355 μm, C. undulatulum: 230–280 × 185–250 μm) (Asgari & Zare 2011, Wang et al. 2016b).Published as part of Mehrabi-Koushki, Mehdi & Safi, Atena, 2023, Chaetomium albiziae, a new endophytic species from Albizia lebbeck in Iran, pp. 137-146 in Phytotaxa 591 (2) on pages 140-142, DOI: 10.11646/phytotaxa.591.2.5, http://zenodo.org/record/779748

No full textPlenodomus dezfulensis M. Mehrabi-Koushki, A. Safi & R. Farokhinejad, sp. nov. (Fig. 3) MycoBank: MB 839660 Holotype: IRAN. Khuzestan Province; Dezful (Safiabad), isolated from leaf spot of Brassica napus subsp. napus (Brassicaceae), December 2019, A. Safi (holotype, IRAN 18084F; ex-type cultures, IRAN 4159C = SCUA-Ahm-S41). Etymology: Species epithet refers to Dezful County in Khuzestan Province (Iran), where the fungus was collected. Asexual morph: Coelomycetous. Conidiomata pycnidial, scattered and irregular, solitary or confluent, partly submerged in the agar, globose to subglobose, with hyphal outgrowths, ostiolate, papillate, brown to tan brown with a darker border, thick-walled, (89–)102–271.4 56.3–238(–263.7) µm, 95% confidence limits = 158.1–182.2 109.8– 129.7 µm, (± SD = 170.1 ± 46.6 119.8 ± 38.6 µm, n= 60). Pycnidial wall variable in thickness, composed of several layers with thick-walled cells of textura angularis, somewhat elongated cells at the base of the pycnidia. Ostioles slightly papillate, with a narrow pore or opening via a rupture. Conidiogenous cells hyaline, smooth, ovoid to doliiform, 3.5–5.2 2.5–4 µm. Conidia ellipsoidal to oblong, rarely allantoid, straight, sometime very slightly curved, hyaline but greyish brown in mass, guttulate near each end, rounded at both ends, aseptate, 3.15–7.4 1– 2.2(–2.7) µm, 95% confidence limits = 4.2–4.7 1.9–2.1 µm, (± SD = 4.5 ± 0.8 1.9 ± 0.3 µm, n= 60). Chlamydospores occasionally found in old cultures, unicellular or occasionally multicellular (pseudosclerotioid and dictyosporous). Swollen cells terminal or intercalary, solitary or in clusters. Sexual morph: not observed. Culture characteristics: colonies on PDA attaining 40–45 mm diam. after 8 days of incubation at 25 ± 0.5 ° C and 52–55 mm diam. at 30 ± 0.5 ° C, circular with filiform margin, initially greenish grey to olivaceous grey, with age becoming darker, finally grey, floccose, in some area covered by dirty-white, woolly mycelial masses; reverse brownish green with a grey margin in young colonies, blackish grey in old colonies. Colonies on OA attaining 43–47 mm diam. after 8 days of incubation at 25 ± 0.5 ° C and 47–50 mm diam. at 30 ± 0.5 ° C, circular with filiform margin, white to dark white, with age becoming grey, cottony and covered by white aerial mycelial, pycnidia scattered in colony margin as black dots; reverse grey. Additional specimen examined: IRAN. Khuzestan Province; Dezful, isolated from leaf spot of Brassica napus subsp. napus (Brassicaceae), January 2020, A. Safi (SCUA-Ahm-S41-2). Note: Plenodomus dezfulensis formed a sister lineage with P. biglobosus (Fig. 2), but it can easily be distinguished from this species by pycnidia having hyphal outgrowths and lacking cylindrical neck (Shoemaker & Brun 2001). Single nucleotide polymorphisms (SNP) analysis of three regions showed the new species and closest strain of P. biglobosus (CBS 119951) had 2 base pair difference (0.46%) across 435 nucleotides of the ITS region, 7 different base pairs (2.3%) across 306 nucleotides of the tub2 region, and a difference of 16 base pairs (2.2%) across 712 nucleotides of the rpb2 region. Two other closely related species of the new species are P. pimpinellae (Lowen & Sivan.) Gruyter, Aveskamp & Verkley, and P. wasabiae. Plenodomus dezfulensis can be easily distinguished from P. pimpinellae by narrower, in culture formed pycnidia lacking long elongated neck (Boerema et al. 2004). In the comparison of DNA sequences of two regions (ITS: 435 bp, tub2: 306 bp), Plenodomus dezfulensis differs from P. pimpinellae in 13 base pairs (1.8%, ITS: 3 bp, tub2: 10 bp) and from P. wasabiae in 12 base pairs (1.6%, ITS: 4 bp, tub2: 8 bp). The rpb2 data of both species are not available for the comparison.Published as part of Safi, Atena, Mehrabi-Koushki, Mehdi & Farokhinejad, Reza, 2021, Plenodomus dezfulensis sp. nov. causing leaf spot of Rapeseed in Iran, pp. 141-154 in Phytotaxa 523 (2) on page 147, DOI: 10.11646/phytotaxa.523.2.2, http://zenodo.org/record/558541
Neochloris oleoabundans from nature to industry: a comprehensive review
No full textMicroalgae technology has been extensively studied during the last two decades. Thousands of species were isolated, and few are currently used in the market for multiple purposes. The current comprehensive review focuses on a promising species named Neochloris oleoabundans. It encompasses a historical overview of the species followed by a detailed description of its taxonomy, ecophysiology and morphology. Furthermore, a thorough screening is conducted to outline the production conditions employed to grow the microalga. In addition, multiple cell disruption and fractionation methods previously applied on N. oleoabundans are described and discussed together with the value chain creation after applying all the unit operations
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Recovery of Post Thyroidectomy Aphonia with Peri Recurrent Laryngeal Nerve Injection of Meloxicam
No full textObjectives: The aim of this study was to assess the effect of perineural injection of meloxicam on the recovery of vocal cord paresis due to recurrent nerve injury after thyroid surgery. A secondary objective was listed the neural inflammation as possible risk factor for delayed recovery of vocal cord paresis.
Methods: 47 years old female, two months after thyroid surgery still complaining of aphonia and dyspnea, due to vocal cord paresis bilaterally, bilaterally injection with 7.5mg of meloxicam was done for peri neural recurrent laryngeal nerve aiming to assess the effect of meloxicam on functional recovery of vocal cord.
Results: A significant improvement in the basic function of vocal cord was noticed immediately after perineural injection of meloxicam bilaterally for recurrent laryngeal nerves injury post thyroidectomy.
Conclusions: Perineural injection of meloxicam appears to be a noval and potentially promising therapeutic option for patients with vocal cord paresis due to transient recurrent laryngeal nerve injury. Further clinical studies are necessary to determine the optimal use of this approach for treatment for both acute and chronic bases.
Neural inflammation of recurrent laryngeal nerve could be possible cause of vocal cord paresis and delayed functional recovery
An ivory bowl from Early Iron Age Tell es-Safi/Gath (Israel): manufacture, meaning and memory
No full textIn 2013, an ivory bowl was discovered in a chalky matrix in the Early Iron Age (Philistine) levels in Area A at Tell es-Safi/Gath. Conservation revealed it to be a shallow vessel with a single lug handle, decorated in the interior and on the base with an incised twelve-petal lotus-rosette surrounded by five concentric circles. Applying an object biography approach, we investigate the history and far-flung socio-cultural connections of the Tell es-Safi/Gath bowl, which is unique within Philistia. Specific reference is made to parallels in the ivory hoard from the Late Bronze/Iron Age transition (c. late twelfth century/early eleventh century bce) palace at Megiddo, Stratum VIIA. It is proposed that the Tell es-Safi/Gath bowl was one of a set manufactured somewhere in Canaan. The vessel became separated from the set, ending up as a foundation offering at this Philistine site

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Horizontal matter fluxes and leaching losses in urban and peri‐urban agriculture of Kabul, Afghanistan
No full textLittle is known about nutrient fluxes and nutrient-use efficiencies in urban and peri-urban agriculture (UPA) of rapidly expanding cities in developing countries. Therefore, horizontal flows of carbon (C), nitrogen (N), phosphorus (P), and potassium (K) as well as leaching losses of mineral N and P were measured over 2 years in three representative agricultural production systems of Kabul. These comprised 21 gardens and 18 fields dedicated to vegetable farming, cereal farming, and table-grape production (vineyards). Across sites (fields and gardens) biennial inputs averaged 375 kg N ha(-1), 155 kg P ha(-1), 145 kg K ha(-1), and 15 kg C ha(-1) while with harvests 305 kg N ha(-1), 40 kg P ha(-1), 330 kg K ha(-1), and 7 kg C ha(-1) were removed. In vegetable gardens, biennial net balances were 80 kg N ha(-1), 75 kg P ha(-1), 205 kg K ha(-1), and 4 kg C ha(-1), whereas in cereal farming biennial horizontal balances amounted to 155 kg N ha(-1), 20 kg P ha(-1), 355 kg K ha(-1), and 5 kg C ha(-1). In vineyards, corresponding values were 295 kg N ha(-1), 235 kg P ha(-1), 5 kg K ha(-1), and 3 kg C ha(-1). Annual leaching losses in two selected vegetable gardens varied from 70 to 205 kg N ha(-1) and from 5 to 10 kg P ha(-1). Night soil and irrigation water were the major sources among the applied nutrient inputs in all studied farming systems, contributing on average 12% and 25% to total N, 22% and 12% to total P, 41% and 53% to total K, and 79% and 10% to total C, respectively. The results suggest that soils in extensive cereal fields are at risk of N and K depletion and in vegetable gardens of K depletion, while vineyards may be oversupplied with nutrients possibly contributing to groundwater contamination. This merits verification
