Sarcopenia involves several mechanisms, including age-related changes, nutritional deficiencies, and inflammation, and is associated with unfavorable clinical outcomes. However, the significance of skeletal muscle index (SMI) and immune-nutritional status for patients with early-stage non-small cell lung cancer (NSCLC) remains unclear. This retrospective study was performed to investigate associations between preoperative SMI based on computed tomography (CT) at the L1 level and immune-nutritional status, and whether these factors correlated with surgical outcomes.We retrospectively investigated 386 patients with stage I-II NSCLC who underwent curative anatomical pulmonary resection. SMI was assessed on CT at the L1 level and patients were divided into low-SMI (n = 97) and high-SMI (n = 289) groups. We examined the significance of SMI for postoperative outcomes and evaluated correlations between SMI and clinical characteristics, including immune-nutritional status.Low SMI was significantly associated with body mass index and geriatric nutritional risk index. Five-year overall survival rate was significantly lower in the low-SMI group (66.0%) than in the high-SMI group (82.2%, P = 0.004). Multivariate analysis revealed SMI (hazard ratio [HR] 1.850; 95% confidence interval [CI] 1.091-3.135; P = 0.022) and prognostic nutritional index (PNI) (HR 2.031; 95% CI 1.231-3.352; P = 0.006) as independent predictors of overall survival. Low SMI correlated significantly with postoperative complications (P = 0.024).Low preoperative SMI based on CT at the L1 level appears associated with poor prognosis and postoperative complications among patients with early-stage NSCLC. PNI is also an independent prognostic factor for surgical outcomes.

The lateral line system and its innervation were examined in two paedomorphic species of Apogonidae, Gymnapogon japonicus and Pseudamiops cf. springeri, both of which have been included in Gymnapogonini (Apogoninae) characterized by a small translucent body lacking canalized lateral line scales, but with many superficial neuromasts (total SNs: 2,691 and 2,197 in G. japonicus and Pseudamiops cf. springeri, respectively). Although scales are entirely absent in G. japonicus, the innervation pattern of the trunk lateral line system is basically similar to that in other apogonids having a single lateral line scale series. In comparison, Pseudamiops cf. springeri (and P. gracilicauda) have three series of inconspicuous lateral line scales with a distinct innervation pattern, implying a phylogenetic affinity with Pseudamia (Pseudamiinae). The monophyly of Pseudamiops and Pseudamia was also supported strongly by a molecular phylogenetic analysis, thus the paedomorphic nature is considered homoplasy between Pseudamiops and Gymnapogon. The innervation of head lateral line system in G. japonicus and Pseudamiops cf. springeri is basically the same with that of other apogonids, supporting homology of the presence of many head SNs among the species. The SN pattern and head canals of adult Pseudamiops cf. springeri are similar to those in juvenile Pseudamia gelatinosa, implying a paedomorphic truncation of lateral line system development in Pseudamiops cf. springeri.

The diagnosis of insulinoma in perinatal women can be difficult, as hypoglycemic symptoms may be masked by pregnancy‐associated insulin resistance. In addition, when multiple insulinomas are observed, it is necessary to consider the possibility not only of MEN1, but also of insulinomatosis.

Background: This study was aimed to compare the efficacy of two combination tablets of DPP-4 inhibitors and metformin with different dosages, alogliptin/metformin (AM) and vildagliptin/metformin (VM), on glycemic control in patients with type 2 diabetes (T2D).Methods: This was a prospective, multicenter, open-label, randomized, parallel group, comparative trial. After a run-in period of treatment with metformin alone, a total of 59 Japanese outpatients with T2D, aged 20-79 years with glycated hemoglobin (HbA1c) levels of 6.5-10% were randomly assigned to 12-week AM treatment, alogliptin 25 mg/metformin 500 mg combination tablet orally once a day, or VM treatment, vildagliptin 50 mg/metformin 250 mg combination tablet orally twice a day. The primary endpoints were the changes in HbA1c and fasting plasma glucose (FPG) levels from baseline to week 12 between the two groups. Blinded intermittently scanned continuous glucose monitoring (isCGM) was performed between weeks 10 and 12. Incidence of adverse events during the study were also evaluated. Results: In all, 52 participants were analyzed. Significant decreases in HbA1c and FPG levels from baseline to week 12 were observed in both treatment groups. However, there were no significant differences between the AM and VM groups in the change in HbA1c level (–0.3% and –0.4%, P = 0.309) or the FPG level (–9.0 mg/dL and –15.0 mg/dL, P = 0.789). The isCGM revealed that both treatments achieved the recommended glycemic target range. No adverse events, such as severe hypoglycemia, were observed in either group.Conclusions: We concluded that there were no significant differences in the efficacy of two combination tablets of DPP-4 inhibitors and metformin with different dosages on glycemic control in patients with T2D.Trial registration: The study was approved by University Hospital Medical Information Network Clinical Trial Registry on the 23rd of August 2018 (Registration No. 000033867).

An ethanolic extract of the stem of Abies spectabilis exhibited strong cytotoxicity against MIA PaCa-2 human pancreatic cancer cells preferentially under nutrient-deprived conditions. Therefore, phytochemical investigation of this bioactive extract was carried out, and that led the isolation of ten compounds (1-10) including a new abietane-type diterpene (1). The structure of the new compound (1) was elucidated by combined spectroscopic techniques, including HRFABMS, NMR and quantum ECD calculation. All the isolated compounds were evaluated for their efficacy against MIA PaCa-2 human pancreatic cancer cell line by employing an anti-austerity strategy. Among the tested compounds, dehydroabietinol (5) displayed the most potent activity with a PC

The lateral line system and its innervation were examined in two species of the family Apogonidae (Cercamia eremia [Apogoninae] and Pseudamia gelatinosa [Pseudamiinae]). Both species were characterized by numerous superficial neuromasts (SNs; total 2,717 in C. eremia; 9,650 in P. gelatinosa), including rows on the dorsal and ventral halves of the trunk, associated with one (in C. eremia) and three (in P. gelatinosa) reduced trunk canals. The pattern of SN innervation clearly demonstrated that the overall pattern of SN distribution had evolved convergently in the two species. In C. eremia, SN rows over the entire trunk were innervated by elongated branches of the dorsal longitudinal collector nerve (DLCN) anteriorly and lateral ramus posteriorly. In P. gelatinosa, the innervation pattern of the DLCN was mirrored on the ventral half of the trunk (ventral longitudinal collector nerve: VLCN). Elongated branches of the DLCN and VLCN innervated SN rows on the dorsal and ventral halves of the trunk, respectively. The reduced trunk canal(s) apparently had no direct relationship with the increase of SNs, because these branches originated deep to the lateral line scales, none innervating canal neuromast (CN) homologues on the surface of the scales. In P. gelatinosa, a CN (or an SN row: CN homologue) occurred on every other one of their small lateral line scales, while congeners (P. hayashii and P. zonata) had an SN row (CN homologue) on every one of their large lateral line scales.

Vertebral bodies of teleost fish are formed by the sclerotomal bone covering the chordacentrum. The internal part of the sclerotomal bone is composed of an amphicoelous hourglass shaped autocentrum, which is common in most fish species. In contrast, the external shape of the sclerotomal bone varies extensively among species. There are multiple hypotheses regarding the composition and formation of the external structure. However, as they are based on studies of few extant or extinct species, their applicability to other species remains to be clarified. To understand the morphology, formation, and composition of vertebral bodies in teleosts, we performed a comparative analysis using micro‐CT scans of 32 species from 10 orders of Teleostei and investigated the detailed morphology of the sclerotomal bone, especially its plate‐like ridge and trabeculae. We discovered two structural characteristics that are shared among most of the examined species. One was the sheet‐like trabeculae that extend radially from the center of the vertebral body with a constant thickness. The other was the presence of hollow spaces on the internal parts of the lateral ridge and trabeculae. The combination of different arrangements of sheet‐like trabeculae and internal hollow spaces formed different shapes of the lateral structure of the vertebral body. The properties of these two characteristics suggest that the external part of the sclerotomal bone grows outward by deposition at the bone tip, and that, concurrently, bone absorption occurs in the internal part of the sclerotomal bone. The vertebral arches were also formed by the sheet‐like trabeculae, indicating that both, the vertebral body and the arches, are formed by the same component. The micro‐CT scanning data were uploaded to a public database so they can be used for future studies on fish vertebrae.

The lateral line system and its innervation were examined in the Nurseryfish Kurtus gulliveri (family Kurtidae). The system is characterized by ca. 373,000 superficial neuromasts (SNs; at 152 mm standard length) occurring over one side of the entire body surface, including the dorsal, anal, and caudal fins. A fine-grid pattern of SNs is spread regularly over the surface, comprising many longitudinal and transverse SN rows, with the axis of best physiological sensibility perpendicular to the long axis of the neuromasts. On the head, rami of the anterior lateral line nerve are similar to those in typical percomorphs, each innervating numerous SNs by extensive ramification. On the trunk, 22 elongated dorsal ramules of the lateral ramus (of the posterior lateral line nerve) supply SNs on the dorsal half of the trunk and dorsal fin, and the dorsal longitudinal collector nerve innervates 22 canal neuromasts along the short (incomplete) trunk lateral line canal. Sixteen ventral ramules arise from the lateral ramus to supply SNs on the ventral half of the trunk and anal fin, which is similar to the pattern of the dorsal ramules. Innervation of the trunk and fins is distinctive, differing from all percomorphs known thus far.

The lateral line system and its innervation were examined in the Japanese eel Anguilla japonica. Although the species has seven lateral line canals and 13 superficial neuromast groups, the components are generally similar to those in many other teleosts. The lateral line system of A. japonica is distinctive in having a rostral commissure connecting the left and right supraorbital canals, pouches in the cephalic lateral line canals and superficial neuromasts along the lower lip, and lacking a postotic canal. Four tube-like elements, two along the supratemporal canal and the other two along the temporal portion of the trunk canal, respectively, are also reported. The functional significance of cephalic lateral line pouches, homologies of the four tube-like elements, and other distinctive characters are discussed.

The cephalic lateral line system and its innervation were examined and compared between the ocular and blind sides in Pardachirus pavoninus (Soleidae). On the ocular side, the otic and preopercular canals were partly (posteriorly and dorsally, respectively) formed by canalized scales (one and five, respectively), each containing a canal neuromast (i.e., “lateral line scales”) and innervated by the anterior lateral line nerve (otic and mandibular rami, respectively). The canal neuromasts of the five scales were recognized as homologous with superficial neuromasts in other taxa based on innervation. The scales, each with a canal perpendicular to the long axis of the scale, bridged the wide gap between the otic region of the cranium and preopercle. The superficial ophthalmic ramus was bifurcated on both sides, the dorsal ramule emerging from the cranium via a frontal foramen. The buccal ramus on the blind side was intensively ramified in the area made available by migration of the eye to the ocular side. The numbers of canal and superficial neuromasts differed greatly between the sides, being 19 and 173 on the ocular side, and 1 and 465 on the blind side, respectively. Sensory strips of superficial neuromasts on the blind side had clear long and short axes. Numerous dermal papillae occurred on the blind side, forming complex channels, according to directions of the long axes.

BackgroundGlucagon stimulation test (GST) is often employed to assess the insulin reserve of the pancreatic beta cells in diabetic subjects. The clinical significance of the increment of plasma glucose (Δglucose) by exogenous glucagon during GST has not been elucidated. We investigated the relationship between Δglucose and clinical parameters including the liver and renal function in type 2 diabetic subjects, since we hypothesized that Δglucose is associated with the liver and renal function reflecting the capacity for gluconeogenesis in the organs.MethodsA total of 209 subjects with type 2 diabetes who underwent GST during admission were included in this cross-sectional study. We defined the difference between plasma glucose at fasting and 6 min after intravenous injection of 1 mg glucagon as Δglucose. We assessed correlations between Δglucose and clinical parameters such as diabetic duration, BMI, HbA1c, beta cell function, serum free fatty acids (FFA) which is known to stimulate gluconeogenesis, liver function, the indices of liver function, renal function, and urinary albumin excretion (UAE).ResultsIn correlation analysis, Δglucose positively correlated to FFA and estimated glomerular filtration rate (eGFR), but inversely to serum creatinine and cystatin C, although Δglucose showed no correlation with both liver function and the indices of residual liver function. Multiple regression analysis revealed that Δglucose was an independent determinant for the eGFR after 1 year, equally BMI, HbA1c, serum lipids, and UAE, which are known as the predictors for the development of chronic kidney disease.ConclusionOur results suggest that Δglucose during GST might be related to gluconeogenesis in the kidney and could be the determinant of future renal function in type 2 diabetes.

A poorly known sculpin, Atopocottus tribranchius Bolin, 1936 (Cottidae), was redescribed on the basis of 56 specimens from several localities in Japan; off Yamaguchi, Kyoto and Niigata Prefectures on the Japan Sea coast, and Kochi Prefecture on the Pacific coast, and in the northern East China Sea. The specimens from Yamaguchi, Kochi and the East China Sea represent the first specimen-based records for the species from those regions. Minute organs on the trunk surface, previously regarded as lateral-line pores, are most likely epidermal pits containing free neuromasts, and lateral-line pores are restricted to a row of embedded lateral-line scales on the anterodorsal portion of the body. Diagnostic characters of the monotypic genus, Atopocottus Bolin, 1936 , are here reviewed on the basis of external and selected osteological characters, described for the first time. The genus is more similar to the Southern Hemisphere (Indonesia, Australia and New Zealand) genus Antipodocottus Bolin, 1952 than to Stlengis Jordan and Starks, 1904, known only from Japan, in having poorly developed cephalic sensory canals with few pores and the lateral-line scales in a simple canal without dorsal and ventral branches. However, Atopocottus differs from Antipodocottus in having fewer lateral-line scales (3–5 vs. 5–33 in the latter); the uppermost preopercular spine with 1–6 dorsal branches, their length and width becoming shorter and narrower, respectively, toward the spine tip, some of them with two spinous points (vs. 2–5 simple, similarly sized dorsal branches); and lacking a supraocular tentacle (vs. usually present). A more comprehensive examination of the two genera is necessary to determine their monophyly.
