Consequences of early adverse rearing experience (EARE) on development: insights from non-human primate studies

Early rearing experiences are important in one’s whole life, whereas early adverse rearing experience (EARE) is usually related to various physical and mental disorders in later life. Although there were many studies on human and animals, regarding the effect of EARE on brain development, neuroendocrine systems, as well as the consequential mental disorders and behavioral abnormalities, the underlying mechanisms remain unclear. Due to the close genetic relationship and similarity in social organizations with humans, non-human primate (NHP) studies were performed for over 60 years. Various EARE models were developed to disrupt the early normal interactions between infants and mothers or peers. Those studies provided important insights of EARE induced effects on the physiological and behavioral systems of NHPs across life span, such as social behaviors (including disturbance behavior, social deficiency, sexual behavior, etc), learning and memory ability, brain structural and functional developments (including influences on neurons and glia cells, neuroendocrine systems, e.g., hypothalamic-pituitary-adrenal (HPA) axis, etc). In this review, the effects of EARE and the underlying epigenetic mechanisms were comprehensively summarized and the possibility of rehabilitation was discussed.
A Simple, Efficient and Rapid Method for Good Quality DNA Extraction from Rice Grains

An efficient and good DNA extraction protocol should be simple, affordable and yield enough DNA with high quality. Rice (Oryza sativa L.) DNA extraction methods often use seedlings or leaves rather than the grains and tend to be time-consuming, involve multiple steps, and use hazardous chemicals and expensive enzymes. Rice grains offer several benefits over seedlings and leaves as a source of DNA for genetic analysis. However, these benefits are underutilized because the bulk of a rice grain is made up of starch. It is particularly important, but difficult to get rid of the starch while extracting DNA from rice grains. This co-precipitated polysaccharide is a known inhibitor of DNA polymerase activity in polymerase chain reaction (PCR). We describe here a very simple and highly affordable Chelex~?-100 based DNA extraction method from rice grains. It does not require any hazardous chemicals or enzymes. This method reproducibly extracts DNA with good purity indices (A_(260)/A_(230) and A_(260)/A_(280) values), but requires only a few steps.
Functional specialization of Nicotiana attenuata phytochromes in leaf development and flowering time

Phytochromes mainly function in photoautotrophic organisms to adjust growth in response to fluctuating light signals. The different isoforms of plant phytochromes often display both conserved and divergent roles, presumably to fine-tune plant responses to environmental signals and optimize fitness. Here we describe the distinct, yet partially redundant, roles of phytochromes NaPHYA, NaPHYB1 and NaPHYB2 in a wild tobacco species, Nicotiana attenuata using RNAi-silenced phytochrome lines. Consistent with results reported from other species, silencing the expression of NaPHYA or NaPHYB2 in N. attenuata had mild or no influence on plant development as long as NaPHYB1 was functional; whereas silencing the expression of NaPHYB1 alone strongly altered flowering time and leaf morphology. The contribution of NaPHYB2 became significant only in the absence of NaPHYB1; plants silenced for both NaPHYB1 and NaPHYB2 largely skipped the rosettestage of growth to rapidly produce long, slender stalks that bore flowers early: hallmarks of the shadeavoidance responses. The phenotyping of phytochrome-silenced lines, combined with sequence and transcript accumulation analysis, suggest the independent functional diversification of the phytochromes, and a dominant role of NaPHYB1 and NaPHYB2 in N. attenuata’s vegetative and reproductive development.

冠心病合并甲基苯丙胺滥用者外伤后自发性心脏破裂1例

如前所述,该男系心脏自发性破裂死亡,案情调查显示外伤仅为被打一个耳光,即面色青紫并倒地,既无心前区遭受外伤的案情,也无相应的尸体解剖所见,故无证据证明外伤与死者心脏破裂死亡之间存在因果关系。然而,由于外伤与死者的死亡过程在客观上有一定的关联度,而且纠纷、争吵等均不可避免地引起死者情绪激动、血压升高、循环加快等应激性反应,从而更易于使原本存在疾病的心脏发生破裂,故外伤可与纠纷、情绪激动等共同考虑为死亡的诱发因素。

Influence of Mg/Al Molar Ratio on the Structures and Properties of Ru-MgAlx Catalysts for Isomerization Linoleic Acid

With the knowledge on the significant effect of basic site and Ru on the catalytic performance of heterogeneous catalysts in the isomerization of linoleic acid to conjugated linoleic acid, a series of Ru-MgAlx compounds with different basicity have been prepared by controlling the Mg/Al molar ratio. The results showed the catalysts with different basicity markedly influence the structure, the Ru dispersion, properties and catalytic performances for the isomerization reaction. The strong basic site is conductive to the high yield of CLA products. The strong basic site and the well-dispersion RuO_2 synergetic catalysis for the isomerization reaction, basic site and the well-dispersion RuO_2 synergetic effect are possibly via a Mg-O-Ru linkage.
High frequency wideband underwater acoustic transducer for ring shaped composite material

A kind of circular ring high frequency wideband underwater acoustic transducer is developed by using the Low Q value and broadband characteristics of the piezoelectricity composite material, and the dual mode coupling is used to broaden the bandwidth of the transducer by double ring stacking along the axial direction. Through theoretical analysis and simulation calculation, the geometric dimensions of the sensitive components are determined. The piezoelectric composite rings are processed and then the stack sensitive element can be made by stacking two piezoelectric composite rings with the same outer diameter and different thickness in axial direction by cutting piezoelectric ceramicsfilling the flexible polymer-coating electrode. Finally, the transducer can be made by pouring waterproof sound-permeable layer. The performances of transducer have also been tested in the water and the test results show that the resonant frequency is 410 kHz, the maximum transmit voltage response is 150 dB, the -3 dB bandwidth can reaches 60 kHz, the horizontal directivity (—5 dB) is 360°, and the vertical directivity (-3 dB) is 20°. It is also shown that the bandwidth of the transducer can be enlarged remarkably by using the method of stacking two different thickness piezoelectric composite rings along the axial direction, and the horizontal omnidirectional emission of acoustic wave can be realized.
Effects of solar reflectance and infrared emissivity of rooftops on the thermal comfort of single-family homes in Mexico

This study developed a series of thermal simulations of buildings under the climatic conditions of 20 cities in Mexico. Thermal comfort was analyzed to examine how it is affected by variations in the solar reflectance and infrared emissivity of the exterior surface of a roof in reference housing. The percentage of uncomfortable hours per year was defined in terms of the PPD index (Predicted Percentage of Dissatisfied) as the fraction of time in which PPD > 20%. Optimal combinations were determined for each city, and it was found that the major effects of the solar reflectance and infrared emissivity occur in cities featuring climates whose ambient temperature is not far away from the comfortable temperature range. The maximum reduction of percentage of uncomfortable hours due to combined effect of solar reflectance and infrared emissivity ranging from 1.9% to 40.6%.

Outcome of distal end clavicle fractures treated with locking plates

Purpose: Fractures of the lateral end of the clavicle are relatively uncommon. These fractures are unstable due to the various deforming forces which act on the fragments as well as the small distal fracture fragment. At most times the deforming forces are not taken into consideration, and the fracture is not fixed securely. In this study, we assessed a fixation technique using the precontoured locking plates to find out whether it provided a stable fixation with good functional outcome. Methods: Totally, 32 patients with lateral end clavicle fracture (Neer's Type II) were included in the study. After the informed consent and preoperative investigations were obtained, open reduction and internal fixation was done using a 3.5 mm precontoured superior locking plate with lateral extension under general anesthesia. Postoperative X-rays were done on day 1 and every 6 weeks after operation, until radiological union was achieved. The postoperative pain was assessed using Visual Analogue Scale (VAS) on postoperative days 1, 2 and 10. Postoperatively arm pouch sling was given for 2 weeks followed by active mobilization. Patients were asked to do their daily routine work and avoid lifting heavy weights. The functional outcome was assessed at the end of 2nd and 6th months with the help of Disabilities of the Arm, Shoulder and Hand (DASH) scoring. Results: There were no intraoperative complications in the procedure. The mean VAS score on postoperative day 1 was found to be 5 which decreased to 3 on day 2 and 0 on day 10. The mean DASH score was calculated as 11.63 at the end of postoperative month 2 and then 4.6 at the end of month 6. There was one case of malunion in whom the overhead abduction was restricted but was not painful and was managed conservatively. Conclusion: The precontoured locking plates with lateral extension may be a good method to fix the fractures of the lateral end clavicle, which provide a stable fixation with good functional outcome with very few instances of stiffness and decreased range of motion of the shoulder with the hook plates and failure of fixation in screw and K-wire fixations. It may well be the answer to the fixation questions of the lateral clavicle fractures, although larger comparative studies between the surgical treatment methods are required to confirm the same.

A Comparative Study of the Cellular Microscopic Characteristics and Mechanisms of Maize Seedling Damage from Superabsorbent Polymers

Superabsorbent polymers (SAPs) as soil moisture conditioners have been increasingly used in agriculture, but conflicting results were reported regarding the effects of SAPs on crop growth. In this study, both laboratory cultivation and analysis were conducted to investigate the effects of different SAPs on the growth and physiology of crops under water-saving agricultural practices. Maize (Zea mays L.) seedlings were cultivated using distilled water or three different SAP hydrogels, sodium polyacrylate (SP),potassium polyacrylate (PP), and sodium polyacrylate embedded with phosphate rock powder (SPP),as growth media. Growth characteristics of the model plant and damage were assessed using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results showed that both the SP and PP treatments had pronounced negative effect on the hydrogels of growth of maize seedlings. The SPP treatment appeared to facilitate the stem-leaf growth and had no obvious adverse effect on root growth. All the three hydrogel treatments caused varying degrees of damage to the organizational structure and cellular morphology of the roots, with the SP and PP treatments causing the most severe damage; the membrane system of root cells was damaged by both SP and PP treatments. An excessive accumulation of sodium and reduction of calcium occurred in the roots may be responsible for the observed damage to the cell membrane system, which, in turn, may have promoted the wilting of the cells.
Remediation of Heavy Metal-Polluted Agricultural Soils Using Clay Minerals: A Review

Heavy metal contamination of agricultural soils poses risks and hazards to humans. The remediation of heavy metal-polluted soils has become a hot topic in environmental science and engineering. In this review, the application of clay minerals for the remediation of heavy metal-polluted agricultural soils is summarized, in terms of their remediation effects and mechanisms, influencing factors, and future focus. Typical clay minerals, natural sepiolite, palygorskite, and bentonite, have been widely utilized for the in-situ immobilization of heavy metals in soils, especially Cd-polluted paddy soils and wastewater-irrigated farmland soils. Clay minerals are able to increase soil pH, decrease the chemical-extractable fractions and bioavailability of heavy metals in soils, and reduce the heavy metal contents in edible parts of plants. The immobilization effects have been confirmed in field-scale demonstrations and pot trials. Clay minerals can improve the environmental quality of soils and alleviate the hazards of heavy metals to plants. As main factors affecting the immobilization effects, the pH and water condition of soils have drawn academic attention. The remediation mechanisms mainly include liming, precipitation, and sorption effects. However, the molecular mechanisms of microscopic immobilization are unclear. Future studies should focus on the long-term stability and improvement of clay minerals in order to obtain a better remediation effect.

Effects of cutting types and hormonal concentration on vegetative propagation of Zanthoxylum armatum in Garhwal Himalaya, India

Experiments were carried out to define the effects of hormonal concentrations on semi-hard wood (SHW) and hard-wood (HW) branch cuttings of the Z armatum. SHW and HW cuttings were collected in the month of March. The SHW and HW cuttings were treated with different concentration of indole-3-acetic acid and indole-3-butyric acid (IAA and IBA) and placed in vermiculite rooting medium for 90 days under 1-min misting after 10 min. Sprouting, rooting percentage, sprout number, sprout length, root number, and length were measured. The highest rooting and sprouting rate, 64.0 %, was obtained at the 0.3 % IBA treatment in the SHW cuttings. Similarly sprout length and number of roots per cutting were also higher at the 0.3 % IBA treatment in the SHW cuttings. The number of shoots per cutting was higher at the 0.3 % IAA treatment in the SHW cuttings. Root length per cutting was higher in 0.4 % IBA treatment in the SHW cuttings. The results indicated that 0.3 and 0.4 % IBA treatment produce higher rooting percentages as well as the number of roots and their length in SHW cuttings. The HW cuttings produced maximum rate of 18.0 % rooting in 0.5 % IBA treatment. The control set and lower concentrations of IBA and IAA completely failed to root in the mist chamber.
Woody species composition and structure of Kuandisha afromontane forest fragment in northwestern Ethiopia

To investigate the woody species composition, diversity and structure of Kuandisha Afromontane forest, vegetation and environmental data were collected from 53 plots of 10 m x 50 m for trees and shrubs and 265 subplots of 2 m x 4 m for seedlings were laid along eight transect lines. The local name, scientific name, abundance, DBH,height and percentage foliage cover of species were recorded. Environmental variables, namely altitude, latitude and longitude as well as disturbance levels were also recorded in each plot. Structure, basal area, importance value index (IVI) and species prioritization were analyzed using spreadsheet programs. Correlation coefficients, frequency, relative frequency, Shannon diversity index, Shannon evenness and vegetation classification were analyzed using an R package. Sixty-six species belonging to 40 families were recorded. Fabaceae was the most diverse family consisting of seven species, followed by Euphor-biaceae and Asteraceae. In terms of habit, 29 species were trees, 28 were shrubs, and 9 were lianas. The overall Shannon diversity index was 2.5. The frequency and relative frequency of woody species with DBH >2.5 cm ranged from 1.9 to 92.5 and 0.1 to 5,respectively. Seedling density varied among species ranging from five to 9938 individuals ha~(-1). The total basal area of woody species having DBH >2.5 cm is 15.3 m~2 ha~(-1). The IVI of species ranged from 0.13 for Solanum giganteum Jacq. to 28.4 for Croton macrostachyus Del. The woody vegetation was classified into five community types. Species richness, diversity and evenness of communities were strongly positively correlated. On the other hand, the correlation between disturbance and seedling density, and species richness was strongly negative. Thus, among the recorded woody species, a significant portion was either lacking regeneration or selectively removed for various purposes. The lack of seedlings of those species is mainly attributed to anthropogenic disturbances particularly free grazing. As a result, 14 tree, seven shrub and one liana species were prioritized for conservation and management interventions.
Linear programming approach for optimal forest plantation

The aim of this research was to identify species suitable for plantation. We first identified species for potentially suitable for plantation based on ecological capabilities regarding soil properties. We determined the area of plantation for different species based on ecological capabilities. Then, we collected relevant data such as growth patterns of different species, labor requirements for plantation and plantation cost. A linear programming model and two integer linear programming models were used for optimization. The appropriate species based on ecological capabilities were ash, elm, maple, oak and bald cypress. A linear programming model was used based on ecological capabilities classification to determine the land area of different species for plantation. Then, two integer linear programming models were employed to select the species for plantation. We set ecological properties unequal for all of the species in the first run of the integer programming model. Two groups were classified: group one included maple and ash; group two included bald cypress, oak and elm. The second integer programming model assumed equal ecological properties for all the species. Results of linear programming showed that maple and bald cypress were appropriate for plantation at the site and their plantation areas should be 151.3 and 355.3 ha, respectively. Results of the first integer linear programming model showed that maple and bald cypress would be economically profitable for plantation. The results of the second integer linear programming model showed that only bald cypress would be appropriate for plantation.
Influence of volcanic activity on vegetation succession and growth environment on the hillslope of Sakurajima Volcano in southern Kyushu,Japan

This study was conducted in order to examine the influence of long-term volcanic activity on vegetative succession and growth on the slope of Sakurajima in southern Kyushu, Japan. We investigated the vegetation, depth of the volcanic ash layer, and dry density and pH of the surface soil at six places on the north-northwestern slope, 2.3-3.4 km from the Minami-dake crater, where a layer of pumice stone was deposited by the Taisho eruption in 1914. The height and diameter at breast height (DBH) of the trees increased with increasing distance from the Minami-dake crater, as did the number of individuals and species, and basal area. The Shannon-Wiener diversity index (H') demonstrates that vegetative succession is significantly affected by distance from the Minami-dake crater, as areas farther from the crater exhibited later serai stages. Comparison of the diversity index and species number of the crater region with that of the climax forest in Kagoshima indicates that vegetative growth alone cannot advance succession in the study area, as the local vegetative community is heavily influenced by the harsh environmental conditions associated with continual exposure to long-term volcanic activity. Seral stage, ash layer depth, dry density, and pH of the soil surface layer are governed by distance from the Minami-dake crater. The results of this study indicate that conditions for vegetative growth and succession improve with increasing distance from the source of constant volcanic activity. Thus, soil development is promoted by the acidification of the soil, which decreases the dry density and pH of the soil surface layer. The introduction of plant species resistant to volcanic ash and gas is recommended to promote soil development and improve the infiltration capacity of the soil.
Effects of soil drought on photosynthetic traits and antioxidant enzyme activities in Hippophae rhamnoides seedlings

Water deficit is one of the major limiting factors in vegetation recovery and reconstruction in the semi-arid area of loess hilly regions. Leaf photosynthesis in Hippophae rhamnoides Linn., a common tree grown in this region, decreases under water stress, but the mechanism responsible is not clear. The objective of this study was to investigate the effects of drought stress on photosynthesis and the relationship between photosynthetic variables and soil water contents to help us better understand the photo-physiological characteristics of H. rhamnoides under water stress and guide cultivation in the loess hilly region. Here, gas exchange, chlorophyll fluorescence and antioxidant enzyme activity in leaves of 3-year-old saplings of H. rhamnoides grown in pots were tested under eight soil water conditions. When soil water content (RWC) was between 38.9 and 70.5 %, stomatal limitation was responsible for the reduced net photosynthetic rate (P_N). When RWC was lower than 38.9 %, nonstomatal limitation was the main factor restricting P_N. Moderate water stress improved the water use efficiency (WUE) of the leaf. Water stress significantly influenced fluorescence variables and the antioxidant enzyme system. When RWC was between 38.9 and 70.5 %,nonphotochemical quenching (NPQ) increased and then decreased, indicating that thermal energy dissipation was a significant photoprotection mechanism. Antioxidant enzymes were activated when RWC ranged from 48.3 to 70.5 %; under severe water stress (RWC < 38.9 %), the antioxidant enzyme system was damaged, the activity of the antioxidant enzymes declined, and membranes were damaged. In the semiarid loess hilly region, RWC between 58.6 and 70.5 % was the economic water threshold value that maintained higher WUE and P_N, and the maximum soil water deficit level that could sustain H. rhamnoides was RWC of 38.9 %.
