Diverse GABAergic neurons organize into subtype‐specific sublaminae in the ventral lateral geniculate nucleus

In the visual system, retinal axons convey visual information from the outside world to dozens of distinct retinorecipient brain regions and organize that information at several levels, including either at the level of retinal afferents, cytoarchitecture of intrinsic retinorecipient neurons, or a combination of the two. Two major retinorecipient nuclei which are densely innervated by retinal axons are the dorsal lateral geniculate nucleus, which is important for classical image‐forming vision, and ventral LGN (vLGN), which is associated with non‐image‐forming vision. The neurochemistry, cytoarchitecture, and retinothalamic connectivity in vLGN remain unresolved, raising fundamental questions of how it receives and processes visual information. To shed light on these important questions, used in situ hybridization, immunohistochemistry, and genetic reporter lines to identify and characterize novel neuronal cell types in mouse vLGN. Not only were a high percentage of these cells GABAergic, we discovered transcriptomically distinct GABAergic cell types reside in the two major laminae of vLGN, the retinorecipient, external vLGN (vLGNe) and the non‐retinorecipient, internal vLGN (vLGNi). Furthermore, within vLGNe, we identified transcriptionally distinct subtypes of GABAergic cells that are distributed into four adjacent sublaminae. Using trans‐synaptic viral tracing and in vitro electrophysiology, we found cells in each these vLGNe sublaminae receive monosynaptic inputs from retina. These results not only identify novel subtypes of GABAergic cells in vLGN, they suggest the subtype‐specific laminar distribution of retinorecipient cells in vLGNe may be important for receiving, processing, and transmitting light‐derived signals in parallel channels of the subcortical visual system.
In Vitro Study on the Effect of a New Bioactive Desensitizer on Dentin Tubule Sealing and Bonding

Bioactive mineral-based dentin desensitizers that can quickly and effectively seal dentinal tubules and promote dentin mineralization are desired. This in vitro study evaluated a novel nanohydroxyapatite-based desensitizer, Predicta (PBD, Parkell), and its effect on bond strength of dental adhesives. Human dentin discs (2-mm thick) were subjected to 0.5 M EDTA to remove the smear layer and expose tubules, treated with PBD, and processed for surface and cross-sectional SEM examination before and after immersion in simulated body fluid (SBF) for four weeks (ISO 23317-2014). The effects of two dental desensitizers on the microshear bond strength of a universal adhesive and a two-step self-etch system were compared. SEM showed coverage and penetration of nanoparticles in wide tubules on the PBD-treated dentin at the baseline. After four weeks in SBF, untreated dentin showed amorphous mineral deposits while PBD-treated dentin disclosed a highly mineralized structure integrated with dentin. Desensitizers significantly reduced microshear bond strength test (MSBS) of adhesives by 15–20% on average, depending on the bonding protocol. In conclusion, PBD demonstrated effective immediate tubules sealing capability and promoted mineral crystal growth over dentin and into the tubules during SBF-storage. For bonding to desensitizer-treated dentin, a two-step self-etching adhesive or universal bond with phosphoric acid pretreatment are recommended.
Overexpression of Kif1A in the Developing Drosophila Heart Causes Valvar and Contractility Defects: Implications for Human Congenital Heart Disease

Left-sided congenital heart defects (CHDs) are among the most common forms of congenital heart disease, but a disease-causing gene has only been identified in a minority of cases. Here, we identified a candidate gene for CHDs, KIF1A, that was associated with a chromosomal balanced translocation t(2;8)(q37;p11) in a patient with left-sided heart and aortic valve defects. The breakpoint was in the 5′ untranslated region of the KIF1A gene at 2q37, which suggested that the break affected the levels of Kif1A gene expression. Transgenic fly lines overexpressing Kif1A specifically in the heart muscle (or all muscles) caused diminished cardiac contractility, myofibrillar disorganization, and heart valve defects, whereas cardiac knockdown had no effect on heart structure or function. Overexpression of Kif1A also caused increased collagen IV deposition in the fibrous network that normally surrounds the fly heart. Kif1A overexpression in C2C12 myoblasts resulted in specific displacement of the F-actin fibers, probably through a direct interaction with G-actin. These results point to a Kif1A-mediated disruption of F-actin organization as a potential mechanism for the pathogenesis in at least some human CHDs.
Lung cancer screening decisional needs among African American smokers of lower socioeconomic status

ABSTRACT Objectives: Adherence to most evidence-based cancer screenings is lower among African Americans due to system- and individual-level factors that contribute to persistent disparities. Given the recommendation for low-dose computed tomography (LDCT) screening among individuals at high risk for lung cancer, we sought to describe aspects of decision-making for LDCT among African Americans and to examine associations between select components of decision-making and screening-related intentions. Design: African Americans (N = 119) with a long-term smoking history, aged 55–80 years, and without lung cancer were recruited to participate in a cross-sectional survey. We measured knowledge, awareness, decisional conflict, preferences, and values related to lung cancer screening. Results: The majority of the study population was of lower socioeconomic status (67.2% had an annual income of ≤$20,000) and long-term current (79%) smokers. Participants had a median 20 pack-years smoking history. Most participants (65.8%) had not heard of LDCT and the total lung cancer screening knowledge score was M = 7.1/15.0 (SD = 1.8). Participants with higher scores on the importance of the pros and cons of screening expressed greater likelihood of talking with a doctor, family, and friends about screening (p’s < .10). Conclusions: Findings have implications for addressing the decisional needs of lower socioeconomic African American current and former smokers to promote informed decision-making for LDCT.
Developmental alterations in the transcriptome of three distinct rodent models of schizophrenia

Schizophrenia is a debilitating disorder affecting just under 1% of the population. While the symptoms of this disorder do not appear until late adolescence, pathological alterations likely occur earlier, during development in utero. While there is an increasing literature examining transcriptome alterations in patients, it is not possible to examine the changes in gene expression that occur during development in humans that will develop schizophrenia. Here we utilize three distinct rodent developmental disruption models of schizophrenia to examine potential overlapping alterations in the transcriptome, with a specific focus on markers of interneuron development. Specifically, we administered either methylazoxymethanol acetate (MAM), Polyinosinic:polycytidylic acid (Poly I:C), or chronic protein malnutrition, on GD 17 and examined mRNA expression in the developing hippocampus of the offspring 18 hours later. Here, we report alterations in gene expression that may contribute to the pathophysiology of schizophrenia, including significant alterations in interneuron development and ribosome function.
Patterns of resistance to organophosphate insecticides in field populations of Helicoverpa armigera in Pakistan

The pattern of organophosphate resistance in field populations of Helicoverpa armigera (Hubner) was monitored in Pakistan from 1994 through 1997 using an IRAC leaf-dip method. Generally, moderate to high resistance was found to an orthophosphorate, monocrotophos and to a dithiophosphorate, ethion. Resistance to the commonly used thiophosphorates, chlorpyrifos and profenofos, was very low during 1994 and 1995 but showed an upward trend during 1996 and 1997. Resistance factors to the other thiophosphorates such as quinalphos, parathion-methyl, methamidophos and triazophos remained very low. Baseline lethal concentrations for ethion, methamidophos and triazophos were at least four to five times higher than those for the other organophosphates tested, suggesting their low intrinsic efficacy against H armigera.
A new approach to validation of periodicity and timing of opaque zone formation in the otoliths of eleven species of Lutjanus from the central Great Barrier Reef*

There have been recent developments in the use of thin sections of otoliths for counting annual increments in otolith macrostructure as accurate and precise indicators of age for a variety of tropical reef species (see Fowler, 1995 for review). Lifespans of 15–30 years were estimated for tropical snappers in Mexico (RochaOlivares, 1998) and the central Great Barrier Reef (GBR) region (Sheaves, 1995; Newman et al., 1996). In contrast, Milton et al. (1995) applied a radiometric aging technique and estimated longevities of <10 years for the “red snappers” Lutjanus erythropterus, L. malabaricus and L. sebae in the Gulf of Carpentaria (lat. <14°S). These results were one third to one half of the maximum ages estimated by Newman et al. (in press) from sectioned otoliths for the same species in the central GBR (lat. 18–20°S). These differences have produced uncer tainty about the nature of potential A new approach to validation of periodicity and timing of opaque zone formation in the otoliths of eleven species of Lutjanus from the central Great Barrier Reef*
A new athecate earthworm of the genus Amynthas Kinberg (Megascolecidae: Oligochaeta) from Taiwan with discussion on phylogeny and biogeography of the A. illotus species-group

This paper describes a new species of athecate earthworm belonging to the illotus species-group of the genus Amynthas Kinberg from Taiwan. It is Amynthas hohuanmontis sp. nov. from Mt Hohuan at an elevation of 3000 m in the Central Mountain Range. The athecate earthworm Amynthas pusillus (Ohfuchi) from Ishigaki Island, Riukiu is found to be synonymous with Amynthas assacceus (Chen) from Hainan Island, China. Accordingly, the A. illotus species-group currently consists of A. hohuanmontis sp. nov. from Taiwan, A. illotus (Gates) from Yunnan and Riukiu, A. assacceus (Chen) of Hainan and Riukiu, A. sheni (Chen) from Hong Kong and A. oyuensis (Ohfuchi) from Japan. Based on characters of particularly the porophore structure, the five species are divided into two species-subgroups: the sheni species-subgroup of A. sheni and A. hohuanmontis, and the assacceus species-subgroup of A. illotus, A. assacceus and A. oyuensis. The two subgroups might have differentiated from two independent ancestors. The five species show an arc-shaped distribution in the peripheral regions of the East Asian continent (Yunnan, Hainan, Hong Kong, Taiwan, Riukiu and Japan), suggesting them to be survivors from the Pleistocene ice ages.
Risk of second primary breast cancer among cancer survivors: Implications for prevention and screening practice

Second primary breast cancer (SPBC) is becoming one of the major obstacles to breast cancer (BC) control. This study was aimed to determine the trend of SPBC incidence over time and the risk of developing SPBC in site-specific primary cancer survivors in the United States. The Surveillance, Epidemiology, and End Results (SEER) 13 registry (1992–2015) was used to identify SPBC patients with previous malignancies. Standardized incidence ratio (SIR) was computed to compare the incidence rates of the observed cases of SPBC in cancer survivors over the expected cases in the general population. Elevated risk of SPBC was observed in women with previous BC (SIR = 1.74) or thyroid cancer (SIR = 1.17). Women with initial skin melanoma in older age (≥50 years) (SIR = 1.11), or White race (SIR = 1.11) presented an elevated incidence of SPBC than the general female population. Besides, Asian/Pacific Islander (API) women with cancer of corpus uteri, ovary, bladder, or kidney were prone to developing SPBC when compared with the general population, with SIRs of 1.61, 1.35, 1.48, and 1.70, respectively. Male BC patients showed profound risk of developing SPBC (SIR = 34.86). Male leukemia patients also presented elevated risk of developing SPBC (SIR = 2.06). Our study suggests significant increase of SPBC in both sexes in the United States. Elevated risk of SPBC exists in survivors with primary BC, female thyroid cancer, male leukemia, and API female cancer patients with primary genitourinary cancer. Our study is helpful in developing strategies for BC control and prevention on specific first primary cancer survivors with an elevated risk of SPBC.
Negative refraction in the visible and strong plasmonic resonances in photonic structures of an electride material Mg2N.

Natural hyperbolic materials have recently attracted great attention due to their capability of supporting spatial mode frequency much higher than artificial metamaterials and the advantage that they do not require nanofabrication processes. For practical applications, however, hyperbolic bulk materials with lower optical losses in shorter wavelength range should be developed. This work presents the electronic structure and dielectric response of electride Mg 2 N, revealing that this material exhibits hyperbolic responses with low optical loss in the visible and plasmonic responses with high-quality in the near-infrared range. Negative refraction in the red spectral range has been analytically and numerically demonstrated. In particular, nanoantenna structures of Mg 2 N generate strong plasmonic resonances in the near-infrared and the intensity enhancement in the gap region is one order of magnitude higher compared with silver nanoantenna due to its much higher quality factor, which can find potential applications for nanoplasmonic purposes such as single molecule detections by surface-enhanced hyper-Raman spectroscopy and nonlinear wavelength generations at the nanoscale.
Circulating microRNAs vs. aortic diameter in bicuspid aortic valve aortopathy

There is growing clinical need and interest to implement novel risk prediction tools in bicuspid aortic valve-associated proximal aortic disease, so-called bicuspid aortic valve aortopathy. Inherent limitations of the diameter-based risk stratification for adverse aortic events in bicuspid aortic valve aortopathy patients have recently been recognized. Therefore, alternative diagnostic tools and subsequent adjustments in the treatment guidelines are urgently needed. Herein, we summarize the current evidence on recent diagnostic developments to improve risk stratification in bicuspid aortic valve aortopathy, including circulating microRNAs as biomarkers to predict the progression of aortic disease.

c-Abl-p38α signaling pathway mediates dopamine neuron loss in trigeminal neuralgia

Trigeminal neuralgia is a common neuropathic pain in the head and face. The pathogenesis of trigeminal neuralgia is complex, and so far, the pathogenesis of trigeminal neuralgia involving peripheral and central nervous inflammation theory has not been explained clearly. The loss of dopamine neurons in striatum may play an important role in the development of trigeminal nerve, but the reason is not clear. C-Abl is a nonreceptor tyrosine kinase, which can be activated abnormally in the environment of neuroinflammation and cause neuron death. We found that in the rat model of infraorbital nerve ligation trigeminal neuralgia, the pain threshold decreased, the expression of c-Abl increased significantly, the downstream activation product p38 was also activated abnormally and the loss of dopamine neurons in striatum increased. When treated with imatinib mesylate (STI571), a specific c-Abl family kinase inhibitor, the p38 expression was decreased and the loss of dopaminergic neurons was reduced. The mechanical pain threshold of rats was also improved. In conclusion, c-abl-p38 signaling pathway may play an important role in the pathogenesis of trigeminal neuralgia, and it is one of the potential targets for the treatment of trigeminal neuralgia.
Bacillus subtilis and Bacillus velezensis population dynamic and quantification of spores after inoculation on ornamental plants.

Bacillus subtilis and Bacillus velezensis are used in organic agriculture as an alternative to chemical pesticides to fight against phytopathogen organisms. These Gram-positive soil-dwelling bacteria are able to resist harsh conditions and survive by differentiating into endospores. Few studies have examined how bacterial populations change on plants over time, and if they remain active or enter a dormant state. Nonetheless, these characteristics are strikingly important to determine the usage of B. subtilis and B. velezensis and their efficacy in environmental conditions. Here, we investigate the population dynamic on plants of B. subtilis NCIB3610 and B. velezensis QST713 when applied as spores on different ornamental plants. We report that on all plants studied (Echinacea purpurea cv. Salsa red, Echinacea purpurea cv. Fatal attraction and Lavandula angustifolia cv. Hidecote blue) spores rapidly germinated and colonized the rhizoplane, maintaining a relatively low proportion of spores in the population over time, whereas bacterial population on leaves rapidly declined. Bacteria in the surrounding soil did not germinate and persisted as spores. Taken together, these results suggest that only cells found at the rhizosphere remain metabolically active to allow the formation of a lasting relationship with the plant, making possible beneficial effects from the inoculated bacteria.
Risk Attitudes of Organic and Conventional Hazelnut Producers in Turkey

ABSTRACT Understanding farmers’ attitudes and responses to agricultural risks is important for designing financial support services and effective extension activities. Risk attitudes of farmers are also one of the critical barriers for conversion to organic agriculture. Few studies have been conducted to explore and compare risk perceptions between organic and conventional farmers. The purposes of this research were to elicit and compare the risk attitudes of organic and conventional Turkish hazelnut producers and to determine the barriers additional to their risk attitudes toward conversion to organic agriculture in the Terme district of Samsun, Turkey. The Equally Likely Certainty Equivalent (ELCE) model was used to elicit responses from producers. The data used in this study were collected by using a structured questionnaire administered to both 64 randomly selected conventional hazelnut producers and all organic hazelnut producers (39) in the research area. Research results revealed that organic hazelnut producers were less risk averse than conventional producers. It was also found that the variables of education level of operators, farm income, total assets, time allocated outside the farm, farm land area, size of hazelnut orchard, number of hazelnut plots, and total information score were other barriers for conversion to organic hazelnut production, in addition to the producers’ risk attitudes. Providing better extension services and farmers’ training activities relating to organic agriculture and land consolidation, focusing on raising the educational level of producers, facilitating producers with greater access to credit to increase farm land and to enhance farm assets are factors that may accelerate the process of conversion to organic hazelnut production.
“Chasing hope”: Parents’ perspectives on complementary and alternative interventions for children with autism in Kazakhstan

In post-Soviet Kazakhstan, the system of care for children with autism has been transforming over the past three decades. There is little known about the use of complementary and alternative medicine by families raising autistic children in the post-Soviet region. An exploratory qualitative focus group design was employed to study parents’ experiences of using complementary and alternative medicine focusing on the perceived factors driving the utilization of complementary and alternative medicine by families of autistic children and the availability of complementary and alternative medicine. Six focus groups were conducted in five cities of diverse geographical locations in Kazakhstan. Data were analyzed using a framework analysis. Two overarching themes and subthemes are developed. The first “unmet needs” relates to predisposing factors that motivate parents to complementary and alternative medicine uptake and the second “chasing hope” relates to enabling factors that facilitate parents’ uptake of complementary and alternative medicines. In summary, parents of autism spectrum disorder children in Kazakhstan face multiple challenges when seeking treatment for their children’s condition and implement whatever complementary and alternative medicine interventions available. A decision to use, and the choice of intervention, mainly comes from perceptions of having no other choice rather than from rational decisions based on efficacy of complementary and alternative medicines. This study provides the first empirical conceptualization of parents’ motives for choosing complementary and alternative medicine in Kazakhstan. Lay abstract The article reports the findings of a qualitative research study on how and why parents of autistic children in Kazakhstan utilize complementary and alternative medicine. We found that parents turn to complementary and alternative medicine because of the lack of professional care options available to them and in pursuit for hope and opportunities for their children with ASD.
