裸根及黑暗模擬貯運對文心蘭生理及形態之影響

The studies were to seek that effect of bare root and dark Simulated transport on physiology and morphology of Colmanara Wildcat. The results showed that ethylene production of Colmanara Wildcat with bare root substantially increase in seventh day in simulated dark transport than that of the control. After simulated dark transport for 5, 7, 10 days that caused the root activity descended, and along with the days after dark treatment, the activity of roots more low. The roots lost activity and dry resulted in loss water, which led Colmanara Wildcat root activity to decrease into 1.01 O.D./g and 0.92 O.D./g and 0.89 O.D./g from original 1.56 O.D./g. The total soulable sugar content of pseudobulb was increase following days past, and the starch content of preudobulb was increase in fifth day then decline in seventh day during dark treatment. 1-aminocyclopropane-1carboxylic acid (ACC) was high in seventh day than that of the control, and 1-aminocyclopropane-1carboxylic acid oxidase (ACO) activity was high, too. The results indicate that dark stress and loss water stress had large effect on bare rooted Colmanara Wildcat with quality or senescence of many examined.本試驗主要探討文心蘭野貓品種Colmanara Wildcat 裸根黑暗模擬貯運不同天數後對生理及形態之影響。文心蘭野貓Colmanara Wildcat經裸根模擬貯運0、5、7及10天，結果顯示，於第7天時乙烯生成量相較於對照組高出甚多，植株根部會因失水導致活力的喪失及乾癟，且根部活力隨天數的增加而下降，經模擬貯運5、7及10天之文心蘭根部活性會由原本的1.56 O.D./g分別降低為1.01 O.D./g、0.92 O.D./g及0.89 O.D./g。模擬貯運過程中假球莖全可溶性糖含量會依天數增加而增加，於第10天時為44.93%DW。而假球莖中澱粉含量則依天數增加而減少。分析ACC生成及ACO活性在模擬貯運第7天時皆高於對照組。試驗中之結果顯示黑暗模擬貯運及缺水逆境會對文心蘭裸根植株的品質及老化上造成莫大的影響。本試驗主要探討文心蘭野貓品種Colmanara Wildcat 裸根黑暗模擬貯運不同天數後對生理及形態之影響。文心蘭野貓Colmanara Wildcat經裸根模擬貯運0、5、7及10天，結果顯示，於第7天時乙烯生成量相較於對照組高出甚多，植株根部會因失水導致活力的喪失及乾癟，且根部活力隨天數的增加而下降，經模擬貯運5、7及10天之文心蘭根部活性會由原本的1.56 O.D./g分別降低為1.01 O.D./g、0.92 O.D./g及0.89 O.D./g。模擬貯運過程中假球莖全可溶性糖含量會依天數增加而增加，於第10天時為44.93%DW。而假球莖中澱粉含量則依天數增加而減少。分析ACC生成及ACO活性在模擬貯運第7天時皆高於對照組。試驗中之結果顯示黑暗模擬貯運及缺水逆境會對文心蘭裸根植株的品質及老化上造成莫大的影響

Measurement of the Bottom-Strange Meson Mixing Phase in the Full CDF Data Set

We report a measurement of the bottom-strange meson mixing phase \beta_s using the time evolution of B0_s -> J/\psi (->\mu+\mu-) \phi (-> K+ K-) decays in which the quark-flavor content of the bottom-strange meson is identified at production. This measurement uses the full data set of proton-antiproton collisions at sqrt(s)= 1.96 TeV collected by the Collider Detector experiment at the Fermilab Tevatron, corresponding to 9.6 fb-1 of integrated luminosity. We report confidence regions in the two-dimensional space of \beta_s and the B0_s decay-width difference \Delta\Gamma_s, and measure \beta_s in [-\pi/2, -1.51] U [-0.06, 0.30] U [1.26, \pi/2] at the 68% confidence level, in agreement with the standard model expectation. Assuming the standard model value of \beta_s, we also determine \Delta\Gamma_s = 0.068 +- 0.026 (stat) +- 0.009 (syst) ps-1 and the mean B0_s lifetime, \tau_s = 1.528 +- 0.019 (stat) +- 0.009 (syst) ps, which are consistent and competitive with determinations by other experiments.Comment: 8 pages, 2 figures, Phys.

In Vitro Laser Treatment Platform Construction with Dental Implant Thread Surface on Bacterial Adhesion for Peri-Implantitis

This study constructs a standard in vitro laser treatment platform with dental implant thread surface on bacterial adhesion for peri-implantitis at different tooth positions. The standard clinical adult tooth jaw model was scanned to construct the digital model with 6 mm bone loss depth on behalf of serious peri-implantitis at the incisor, first premolar, and first molar. A cylindrical suite connected to the implant and each tooth root in the jaw model was designed as one experimental unit set to allow the suite to be replaced for individual bacterial adhesion. The digital peri-implantitis and suite models were exported to fulfill the physical model using ABS material in a 3D printer. A 3 mm diameter specimen implant on bacterial adhesion against Escherichia coli was performed for gram-negative bacteria. An Er:YAG laser, working with a chisel type glass tip, was moved from the buccal across the implant thread to the lingual for about 30 seconds per sample to verify the in vitro laser treatment platform. The result showed that the sterilization rate can reach 99.3% and the jaw model was not damaged after laser irradiation testing. This study concluded that using integrated image processing, reverse engineering, CAD system, and a 3D printer to construct a peri-implantitis model replacing the implant on bacterial adhesion and acceptable sterilization rate proved the feasibility of the proposed laser treatment platform.</jats:p

High-level expression and molecular characterization of a recombinant prolidase from Escherichia coli NovaBlue

Long-term use of organophosphorus (OP) compounds has become an increasing global problem and a major threat to sustainability and human health. Prolidase is a proline-specific metallopeptidase that can offer an efficient option for the degradation of OP compounds. In this study, a full-length gene from Escherichia coli NovaBlue encoding a prolidase (EcPepQ) was amplified and cloned into the commercially-available vector pQE-30 to yield pQE-EcPepQ. The overexpressed enzyme was purified from the cell-free extract of isopropyl thio-β-D-galactoside IPTG-induced E. coli M15 (pQE-EcPepQ) cells by nickel-chelate chromatography. The molecular mass of EcPepQ was determined to be about 57 kDa by 12% sodium dodecyl sulfate–polyacrylamide gel electrophoresis and the result of size-exclusion chromatography demonstrated that the enzyme was mainly present in 25 mM Tris–HCl buffer (pH 8.0) as a dimeric form. The optimal conditions for EcPepQ activity were 60 °C, pH 8.0, and 0.1 mM Mn2+ ion. Kinetic analysis with Ala-Pro as the substrate showed that the Km and kcat values of EcPepQ were 8.8 mM and 926.5 ± 2.0 s−1, respectively. The thermal unfolding of EcPepQ followed a two-state process with one well-defined unfolding transition of 64.2 °C. Analysis of guanidine hydrochloride (GdnHCl)-induced denaturation by tryptophan emission fluorescence spectroscopy revealed that the enzyme had a [GdnHCl]0.5,N-U value of 1.98 M. The purified enzyme also exhibited some degree of tolerance to various water/organic co-solvents. Isopropanol and tetrahydrofuran were very detrimental to the enzymatic activity of EcPepQ; however, other more hydrophilic co-solvents, such as formamide, methanol, and ethylene glycol, were better tolerated. Eventually, the non-negative influence of some co-solvents on both catalytic activity and structural stability of EcPepQ allows to adjust the reaction conditions more suitable for EcPepQ-catalyzed bioprocess

A novel SEPT12 mutation, T96I, is associated with sperm head and annulus defects

Infertility affects around 8%–12% of reproductive-aged couples and is a major health concern. Both genetic and environmental factors influence male infertility. SEPTIN12 is a crucial testis-specific gene essential for the final differentiation of male germ cells and is strongly linked to male infertility due to numerous detected mutations. The present study identified a novel SEPTIN12T96I mutation that causes male infertility. Immunofluorescence staining and transmission electron microscopy (TEM) analysis of T96I sperm revealed co-localization of SEPT12 and SEPT7 in the obliquely positioned annulus. In addition, the sperm carrying the T96I mutation demonstrated large nuclear vacuoles, irregular swelling, and decondensation of the acrosomal cap. The overexpression of SEPT12 T96I in NT2/D1 cells impaired the formation of SEPT7 filaments, emphasizing the significance of SEPT12 filaments for sperm morphology and function. Our results demonstrate the importance of SEPTIN12T96I in male infertility and offer valuable insights for future detection in infertile men

Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe

Authoritarianism in the Living Room: Everyday Disciplines, Senses, and Morality in Taiwan’s Military Villages

With the nationalist government – Kuomintang (KMT) – retreating from mainland China in 1949, some 600,000 military personnel relocated to Taiwan. The military seized former Japanese colonial properties and built its own settlements, establishing temporary military dependents’ villages called juancun (眷村). When the prospect of counter-attacking the mainland vanished, the KMT had to face the reality of settling permanently in Taiwan. How, then, did the KMT’s authoritarian power enter the everyday lives of its own support group? In this article I will focus on the coercive elements of KMT authoritarianism, which permeated these military villages in Taiwan. I will look at the coercive mechanisms through the analytical lens of Foucauldian discipline. I argue that disciplinary techniques such as surveillance, disciplining of the body and the senses, as well as the creation of morality regimes played an important role in the cooptation of village residents into KMT authoritarianism by normalising and naturalising it
