Cladosporium species are cosmopolitan fungi, characterized by olivaceous or dark colonies with coronate conidiogenous loci and conidial hila with a central convex dome surrounded by a raised periclinal rim. Cladosporium species have also been discovered in marine environments. Although many studies have been performed on the application of marine originated Cladosporium species, taxonomic studies on these species are scarce. We isolated Cladosporium species from three under-studied habitats (sediment, seawater, and seaweed) in two districts including an intertidal zone in the Republic of Korea and the open sea in the Western Pacific Ocean. Based on multigenetic marker analyses (for the internal transcribed spacer, actin, and translation elongation factor 1), we identified fourteen species, of which five were found to represent new species. These five species were C. lagenariiforme sp. nov., C. maltirimosum sp. nov., C. marinum sp. nov. in the C. cladosporioides species complex, C. snafimbriatum sp. nov. in the C. herbarum species complex, and C. marinisedimentum sp. nov. in the C. sphaerospermum species complex. Morphological characteristics of the new species and aspects of differences with the already known species are described herein together with molecular data.

The COSINE-100 experiment has been operating with 106 kg of low-background NaI(Tl) detectors to test the results from the DAMA/LIBRA experiment, which claims to have observed dark matter. However, since the background of the NaI(Tl) crystals used in the COSINE-100 experiment is 2–3 times higher than that in the DAMA detectors, no conclusion regarding the claimed observation from the DAMA/LIBRA experiment could be reached. Therefore, we plan to upgrade the current COSINE-100 experiment to the next phase, COSINE-200, by using ultra-low background NaI(Tl) detectors. The basic principle was already proved with the commercially available Astro-grade NaI powder from Sigma-Aldrich (now Merck) company. However, we have developed a mass production process of ultra-pure NaI powder at the Center for Underground Physics (CUP) of the Institute for Basic Science (IBS), Korea, using the direct purification of the raw NaI powder. We plan to produce more than 1,000 kg of ultra-pure powder for the COSINE-200 experiment. With our crystal grower installed at CUP, we have successfully grown a low-background crystal using our purification technique for the NaI powder. We have assembled a low-background NaI(Tl) detector. In this article, we report the performance of this ultra-pure NaI(Tl) crystal detector produced at IBS, Korea.

Objective To investigate whether lumbar lordosis (LL) and lumbar segmental lordosis (LSL) are related to sex, age, low back pain (LBP), and lumbar disc space narrowing (DSN).Methods A total of 569 farmers were recruited. In lateral spine radiograph, LL (L1–L5) and LSL (L1, L2, L3, L4, and L5) were measured using Cobb’s method. The differences in LSL values (ΔLSL) according to the presence or absence of a DSN were calculated as LSLDSN – LSLnoDSN for each DSN level.Results In male, the lateral spine radiograph showed significantly greater L4-LSL and L5-LSL and smaller L1-LSL and L2-LSL compared to female. LLs in the 50–59 and ≥60 years age groups were significantly smaller compared to those in the

We herein report a case in which a cystic artery arising from the middle hepatic artery (MHA) was encountered during cholecystectomy. A 42-year-old man visited the outpatient department complaining of chronic epigastric pain and a laparoscopic cholecystectomy was decided upon. During the preoperative evaluation, an interesting finding was observed on computed tomography. The patient had a cystic artery arising from the MHA. An MHA derived from the hilum of the proper hepatic artery runs along the medial border of the gallbladder and enters segment IV. In the operative field, the MHA that entered segment IV was observed. Dissecting downward along the MHA, a cystic artery was observed around the cystic duct. The cystic artery and duct were isolated and each was separately ligated and cut. Rare anatomical variations of the cystic artery, as in this case, can be a pitfall inducing complications during cholecystectomy.

Etymology. The new species name uniplicata is from the combination of the Latin words uni, meaning ���one��� and plica, meaning ���fold or ridge���, alluding to the single oblique ridge on the carapace. Remarks. This new species Diastylis uniplicata sp. nov. has a unique combination of characteristics: carapace surface smooth, with a transverse ridge on frontal lobe; both sides of carapace with a pair of oblique ridges beginning near antero-lateral corner, running upward and connecting to the dorsal median carina; telson 1.7 times as long as pleonite 6, with 5���6 simple setae laterally. The most similar species are D. antillensis Sars, 1873 and D. planifrons Calman, 1912, which have a pair of oblique ridges beginning near the antero-lateral corner and running upward. These species, however, lack a transverse ridge on frontal lobe of carapace. Also, oblique ridges on the carapace in D. antillensis and D. planifrons are W-shaped in dorsal view, compared C-shaped in D. uniplicata sp. nov.. Depth. 2 m. Distribution.

Summary Background Isatuximab is an anti-CD38 monoclonal antibody approved in combination with pomalidomide–dexamethasone and carfilzomib–dexamethasone for relapsed or refractory multiple myeloma. This phase 3, open-label study compared the efficacy of isatuximab plus carfilzomib–dexamethasone versus carfilzomib–dexamethasone in patients with relapsed multiple myeloma. Methods This was a prospective, randomised, open-label, parallel-group, phase 3 study done at 69 study centres in 16 countries across North America, South America, Europe, and the Asia-Pacific region. Patients with relapsed or refractory multiple myeloma aged at least 18 years who had received one to three previous lines of therapy and had measurable serum or urine M-protein were eligible. Patients were randomly assigned (3:2) to isatuximab plus carfilzomib–dexamethasone (isatuximab group) or carfilzomib–dexamethasone (control group). Patients in the isatuximab group received isatuximab 10 mg/kg intravenously weekly for the first 4 weeks, then every 2 weeks. Both groups received the approved schedule of intravenous carfilzomib and oral or intravenous dexamethasone. Treatment continued until progression or unacceptable toxicity. The primary endpoint was progression-free survival and was assessed in the intention-to-treat population according to assigned treatment. Safety was assessed in all patients who received at least one dose according to treatment received. The study is registered at ClinicalTrials.gov, NCT03275285. Findings Between Nov 15, 2017, and March 21, 2019, 302 patients with a median of two previous lines of therapy were enrolled. 179 were randomly assigned to the isatuximab group and 123 to the control group. Median progression-free survival was not reached in the isatuximab group compared with 19·15 months (95% CI 15·77–not reached) in the control group, with a hazard ratio of 0·53 (99% CI 0·32–0·89; one-sided p=0·0007). Treatment-emergent adverse events (TEAEs) of grade 3 or worse occurred in 136 (77%) of 177 patients in the isatuximab group versus 82 (67%) of 122 in the control group, serious TEAEs occurred in 105 (59%) versus 70 (57%) patients, and TEAEs led to discontinuation in 15 (8%) versus 17 (14%) patients. Fatal TEAEs during study treatment occurred in six (3%) versus four (3%) patients. Interpretation The addition of isatuximab to carfilzomib–dexamethasone significantly improves progression-free survival and depth of response in patients with relapsed multiple myeloma, representing a new standard of care for this patient population.

Etymology. The new species name incarinata is from the combination of the Latin words in, meaning ‘no’ and carinatus, meaning ‘shaped like a keel’, alluding to the lack of any dorso-lateral carina on the carapace. Remarks. This new species Bodotria (Atlantobodotria) incarinata sp. nov. is similar to B. (A.) corallina Mühlenhardt-Siegel, 2000 and B. (A.) nitida Day, 1978 in the combination of the following features: 1) carapace smooth, without dorso-lateral carina and lateral ridge or other structures; 2) antennal notch shallow in male; 3) antero-lateral corner rounded; 4) uropod endopod 2-articulate. B. (A.) nitida is easily distinguished from similar species because of the articulatory peg present between carapace and second pereonite dorso-laterally, and third to fifth pereonites slightly elevated dorsally. Also, the new species is obviously distinguished from B. (A.) corallina by the following features (Table 1, condition of B. (A.) corallina in parenthesis) male: 1) carapace, dorsomedian carina marked over whole length of carapace (vs. dorso-median carina not pronounced); 2) maxilliped 3, exopod 6-articulate and shorter than basis; merus and carpus dilated; (vs. exopod 7-articulate and almost subequal to basis; merus not dilated); 3) pereopod 2, basis with plumose seta (vs. without plumose seta); 4) uropod endopod little shorter than exopod length (vs. little longer than exopod length).

However, the new species is obviously distinguished from B. (B.) maculosa by the combination of the following features (Table 1, condition of B. (B.) maculosa in parentheses): 1) carapace, lower edge of mid-lateral depression forming an angular ridge (vs. with a prominent longitudinal ridge and curves up posteriorly to meet the carina), 2) ocular lobe with 8 lenses (vs. with 9 lenses); 3) third and fourth pereonites, dorso-median carina slight elevated posteriorly (vs. dorso-median carina of third to fifth pereonites elevated posteriorly); 4) thoracic appendages, margins not serrate (vs. more or less serrate); 5) uropod peduncle with plumose and microserrate setae medially (vs. with only plumose seta).

Etymology. The new species name incarinata is from the combination of the Latin words in, meaning ‘no’ and carinatus, meaning ‘shaped like a keel’, alluding to the lack of any dorso-lateral carina on the carapace. Remarks. This new species Bodotria (Atlantobodotria) incarinata sp. nov. is similar to B. (A.) corallina Mühlenhardt-Siegel, 2000 and B. (A.) nitida Day, 1978 in the combination of the following features: 1) carapace smooth, without dorso-lateral carina and lateral ridge or other structures; 2) antennal notch shallow in male; 3) antero-lateral corner rounded; 4) uropod endopod 2-articulate. B. (A.) nitida is easily distinguished from similar species because of the articulatory peg present between carapace and second pereonite dorso-laterally, and third to fifth pereonites slightly elevated dorsally. Also, the new species is obviously distinguished from B. (A.) corallina by the following features (Table 1, condition of B. (A.) corallina in parenthesis) male: 1) carapace, dorsomedian carina marked over whole length of carapace (vs. dorso-median carina not pronounced); 2) maxilliped 3, exopod 6-articulate and shorter than basis; merus and carpus dilated; (vs. exopod 7-articulate and almost subequal to basis; merus not dilated); 3) pereopod 2, basis with plumose seta (vs. without plumose seta); 4) uropod endopod little shorter than exopod length (vs. little longer than exopod length). Depth. 2–5 m. Distribution. Korea (Yellow Sea).

The new species is named paraspinifera from the Latin para, meaning like, in reference to the similarity of this species to the Bodotria spinifera. Remarks. This new species Bodotria paraspinifera sp. nov. is similar to B. carinata Gam��, 1964 and B. spinifera Gam��, 1986 in the combination of the following features: 1) dorso-lateral carina of carapace well-developed; 2) carapace almost rectangular in dorsal view; 3) carpus of pereopod 1 dilated; 4) pereopod 2 without ischium, dactylus longer than propodus; 5) uropod endopod uniarticulate. However, B. carinata is different from B. paraspinifera sp. nov. and B. spinifera, because body not covered with spinule. Also, the new species is obviously distinguished from B. spinifera by a combination of the following features (B. spinifera condition in parentheses): 1) body covered with numerous spinules (vs. partly spinulose and covered with minute reticulated patterns); 2) anterior portion of carapace gradually narrows forward at about 1/5 (vs. suddenly narrows forward at about 1/4); 3) dorso-lateral carina with marginal spinules on entire length of the carapace (vs. with marginal spines runs along entire length of the carapace except at the anterior portion); 4) basis of pereopod 1 with numerous small tubercles in rows on medial surface, exopod 6-s, Published as part of Kim, Sung-Hyun, Lee, Chang-Mok & Kim, Young-Hyo, 2020, Bodotria paraspinifera sp. nov.

Accurate quantification of pulmonary nodules can greatly assist the early diagnosis of lung cancer, which can enhance patient survival possibilities. A number of nodule segmentation techniques have been proposed, however, all of the existing techniques rely on radiologist 3-D volume of interest (VOI) input or use the constant region of interest (ROI) and only investigate the presence of nodule voxels within the given VOI. Such approaches restrain the solutions to investigate the nodule presence outside the given VOI and also include the redundant structures into VOI, which may lead to inaccurate nodule segmentation. In this work, a novel semi-automated approach for 3-D segmentation of nodule in volumetric computerized tomography (CT) lung scans has been proposed. The proposed technique can be segregated into two stages, at the first stage, it takes a 2-D ROI containing the nodule as input and it performs patch-wise investigation along the axial axis with a novel adaptive ROI strategy. The adaptive ROI algorithm enables the solution to dynamically select the ROI for the surrounding slices to investigate the presence of nodule using deep residual U-Net architecture. The first stage provides the initial estimation of nodule which is further utilized to extract the VOI. At the second stage, the extracted VOI is further investigated along the coronal and sagittal axis with two different networks and finally, all the estimated masks are fed into the consensus module to produce the final volumetric segmentation of nodule. The proposed approach has been rigorously evaluated on the LIDC dataset, which is the largest publicly available dataset. The result suggests that the approach is significantly robust and accurate as compared to the previous state of the art techniques., Comment: The manuscript is currently under review and copyright shall be transferred to the publisher upon acceptance

Precise allergy diagnosis and effective allergen specific immunotherapy are largely dependent on the quality of allergen extract. A new extract of Dermatophagoides farinae was commercially developed by Prolagen. The allergenic properties of the new extract were compared with those of other commercial products. The allergenic properties of the new extract were compared according to protein concentration, protein profiles, major allergen (Der f 1) contents, and allergenic potency to those for three commercially available extracts imported in Korea (Jubilant HollisterStier Allergy, Lofarma S.p.A., and Stallergenes Greer). Protein concentrations varied up to 2.62-fold (0.404 to 1.057 mg/mL), and Der f 1 contents varied up to 11.3-fold (3.597 to 40.688 µg/mL). Protein profiles of the extracts showed no major discrepancies, although there were some differences in SDS-PAGE band intensities, reflecting protein concentrations. Allergen potency ranged from 37038 to 60491 PAU/mL. The Prolagen product was highest in terms of protein concentration and allergen potency. The Lofarma product displayed Der f 1 content similar to that in Prolagen (19.4 µg/mg vs. 19.3 µg/mg). Endotoxin levels varied 8.9-fold (1020 to 8985 EU/mL). The newly developed house dust mite extract showed equal or better allergenic properties than available commercial extracts. This new product may be useful for better diagnostics and allergen-specific immunotherapeutics.

Remarks. Nannastacus spinulosus Gam��, 1962 is morphologically characterized by having numerous spinules and spines on surface of the body including the carapace, pereon, and pleon. Our specimens are in good agreement with the original description given by Gam�� (1962) as follows: 1) ornament patterns of spinules and spines on surface of the body; 2) relative length of segments in pereopod 1; 3) relative length ratio of uropod peduncle, exopod, endopod, and pleotelson. However, several minor differences are found between our specimens and the previous report by Gam�� (1962) (original descriptions in parentheses): 1) carapace and pereon with short plumose setae (vs. without plumose setae); 2) carapace subequal to 1/3 length of body (vs. nearly 1/5); 3) pleon 0.84 times as long as cephalothorax (vs. 0.70 times) 4) maxilliped 3, basis with hair-like setae on each margin (vs. without hair-like setae). It is possible that Gam�� overlooked these minor characteristics. Distribution.

This new species Bodotria jejuensis sp. nov. is similar to B. similis Calman, 1907, B. rugosa Gamô, 1963, B. carinata Gamô, 1964, and B. biplicata Gamô, 1964 which are distributed in Japanese waters, in having a pitted carapace and well-marked dorso-lateral carina. However, the new species is obviously distinguished from its congeners by a combination of the following features (based on list in Table 1): 1) carapace longish elliptical in dorsal view (vs. subquadrangular in B. carinata); 2) carapace, lateral carina slightly curved, almost reaching end of posterior margin (vs. curved dorsally, reaching 2/3 length of carapace in B. rugosa and B. biplicata; straight, near end of posterior margin in B. carinata); 3) carapace, lateral longitudinal ridge distinct, curved upwards posteriorly to merge with lateral carina (vs. almost parallel to the lateral carina in B. rugosa, B. biplicata, and B. similis; absent in B. carinata); 4) dorsal carina of free thoracic segment moderately elevated (vs. strongly elevated in B. carinata and B. similis); 5) free thoracic segment with well-marked lateral carina (vs. without lateral carina in B. biplicata); 6) free thoracic segments 3–5 subquadrate in lateral view (vs. subtriangular in B. biplicata and B. similis); 7) pereopod 1, carpus dilated laterally (vs. not dilated in B. rugosa, B. biplicata, and B. similis); 8) pereopod 2, basis with 10 short simple, 1 simple, and 1 complex pedunculated setae in female (vs. serration in B. rugosa; 4 plumose setae in B. biplicata; 1 simple seta in B. carinata; 4 plumose setae in B. similis). On the other hand, Gamô (1962) dealt with geographical and individual variation of Bodotria similis with male and female specimens (3.8–4.8mm) collected from Omai Zaki, Japan. They are also similar to B. jejuensis sp. nov in having the lateral ridge, laterally dilated carpus on pereopod 1, and relatively long uropod. However, the new species is obviously distinguished from B. smilis reported from Japanese waters by a combination of following features: 2) free thoracic segment lateral carina well-marked (vs. faintly marked in developing marsupium female); 1) carapace, lateral ridge well developed, curved upwards posteriorly to merge with lateral carina (vs. faint, almost parallel to the lateral carina in mature male, without lateral ridge in developing marsupium female); 3) pereopod 1, carpus dilated laterally (vs. not dilated in mature male); 4) free thoracic segment 3–5 subquadrate in lateral view (vs. subtriangular). Distribution. Korea (Jeju-do Is., shallow water, 6m).

This new species Bodotria jejuensis sp. nov. is similar to B. similis Calman, 1907, B. rugosa Gam��, 1963, B. carinata Gam��, 1964, and B. biplicata Gam��, 1964 which are distributed in Japanese waters, in having a pitted carapace and well-marked dorso-lateral carina. However, the new species is obviously distinguished from its congeners by a combination of the following features (based on list in Table 1): 1) carapace longish elliptical in dorsal view (vs. subquadrangular in B. carinata); 2) carapace, lateral carina slightly curved, almost reaching end of posterior margin (vs. curved dorsally, reaching 2/3 length of carapace in B. rugosa and B. biplicata; straight, near end of posterior margin in B. carinata); 3) carapace, lateral longitudinal ridge distinct, curved upwards posteriorly to merge with lateral carina (vs. almost parallel to the lateral carina in B. rugosa, B. biplicata, and B. similis; absent in B. carinata); 4) dorsal carina of free thoracic segment moderately elevated (vs. strongly elevated in B. carinata and B. similis); 5) free thoracic segment with well-marked lateral carina (vs. without lateral carina in B. biplicata); 6) free thoracic segments 3���5 subquadrate in lateral view (vs. subtriangular in B. biplicata and B. similis); 7) pereopod 1, carpus dilated laterally (vs. not dilated in B. rugosa, B. biplicata, and B. similis); 8) pereopod 2, basis with 10 short simple, 1 simple, and 1 complex pedunculated setae in female (vs. serration in B. rugosa; 4 plumose setae in B. biplicata; 1 simple seta in B. carinata; 4 plumose setae in B. similis). On the other hand, Gam�� (1962) dealt with geographical and individual variation of Bodotria similis with male and female specimens (3.8���4.8mm) collected from Omai Zaki, Japan. They are also similar to B. jejuensis sp. nov in having the lateral ridge, laterally dilated carpus on pereopod 1, and relatively long uropod. However, the new species is obviously distinguished from B. smilis reported from Japanese waters by a combination of following features: 2) free thoracic segment lateral carina well-marked (vs. faintly marked in developing marsupium female); 1) carapace, lateral ridge well developed, curved upwards posteriorly to merge with lateral carina (vs. faint, almost parallel to the lateral carina in mature male, without lateral ridge in developing marsupium female); 3) pereopod 1, carpus dilated laterally (vs. not dilated in mature male); 4) free thoracic segment 3���5 subquadrate in lateral view (vs. subtriangular).
