Working toward an integrated plasticity/network framework for repetitive transcranial magnetic stimulation to inform tailored treatments

Non-invasive brain stimulation techniques(NIBS),including repetitive transcranial magnetic stimulation(rTMS) and transcranial electric stim ulation(tES),are increasingly being adopted clinically for treatment of neuropsychiatric and neurological disorders,albeit with varying success.The rationale behind the use of NIBS has historically been that stim ulation techniques modulate neuronal activity in the targeted region and consequently induce plasticity which can lead to therapeutic outcomes.

Model-based interpretation of bottomhole pressure records during matrix treatments in layered formations

During injection treatments, bottomhole pressure measurements may significantly mismatch modeling results. We devise a computationally effective technique for interpretation of fluid injection in a wellbore interval with multiple geological layers based on the bottomhole pressure measurements. The permeability, porosity and compressibility in each layer are initially setup, while the skin factor and partitioning of injected fluids among the zones during the injection are found as a solution of the problem. The problem takes into account Darcy flow and chemical interactions between the injected acids, diverter fluids and reservoir rock typical in modern matrix acidizing treatments. Using the synchronously recorded injection rate and bottomhole pressure, we evaluate skin factor changes in each layer and actual fluid placement into the reservoir during different pumping jobs: matrix acidizing, water control, sand control, scale squeezes and water flooding. The model is validated by comparison with a simulator used in industry. It gives opportunity to estimate efficiency of a matrix treatment job, role of every injection stage, and control fluid delivery to each layer in real time. The presented interpretation technique significantly improves accuracy of matrix treatments analysis by coupling the hydrodynamic model with records of pressure and injection rate during the treatment.

Valvular heart disease and cardiomyopathy in China:epidemiology and current treatments

The Annual Report on Cardiovascular Health and Diseases in China(2022)intricate landscape of cardiovascular health in China.In connection with the previous section,this ninth section of the report offers a comprehensive analysis of valvular heart disease and cardiomyopathy.Although rheumatic valve disease is still the main cause of valvular heart disease in China,with the aging of the population and the improvement of living standards,the prevalence of degenerative valvular heart disease is on the rise.Because many patients with valvular heart disease have only mild to moderate valve stenosis or insufficiency,and no symptoms,the detection rate in the population is low and late,resulting in many patients been in the severe late stage of disease at visit,increasing the difficulty of treatment and affecting effectiveness and prognosis.Therefore,we should strengthen the examination and screening of valvular heart disease in order to find and prevent it as early as possible.In addition,compared with other diseases,the treatment of valvular heart disease needs more and higher technical support(surgery,intervention,etc).However,not all hospitals can provide relevant technologies.At present,the treatment of valvular heart disease is still mainly concentrated in the provincial hospitals.It is necessary to carry out more professional training so that more doctors and hospitals can participate in the treatment of valvular heart disease.Cardiomyopathy is a group of myocardial diseases with abnormal myocardial structure and/or function,but couldn't be explained by hypertension,coronary atherosclerosis,valvular heart disease and congenital heart disease.It includes hypertrophic cardiomyopathy(HCM),dilated cardiomyopathy(DCM),arrhythmogenic cardiomyopathy(also known as arrhythmogenic right ventricular cardiomyopathy),restrictive cardiomyopathy(RCM)and undifferentiated cardiomyopathy.

Exploring the Trait Plasticity of ipa1-2D and qPL6 under Different Nitrogen Treatments and Heading Periods

Panicle size is one of the important factors in shaping yield potential in rice,but it shows plasticity in different environments,which leads to yieldfluctuation.Variations in panicle size among varieties are largely determined by quantitative trait loci(QTLs).QTL analysis could elaborate on the environmental impact on trait plasticity using nearly isogenic lines(NILs)of different QTLs.Two QTLs,ipa1-2D and qPL6 are identified to have pleio-tropic contributions to panicle size and plant architecture,but their responses to different growth conditions are still unclear.In this study,we developed NILs harboring a single locus or both loci of ipa1-2D and qPL6 and sub-sequently evaluated these QTL effects under different nitrogen treatments or heading periods.Trait comparison showed that panicle length was highly responsive to the high nitrogen treatment independent of qPL6.At the same time,ipa1-2D reduced the response of plant height,panicle number,and grain yield to the treatment.The background of long heading periods decreased the stem diameter for any genotype combinations but enhanced the performance of ipa1-2D for the panicle primary branch number.Moreover,the middle heading background could better balance the pleiotropic effect of the two QTLs and showed the highest yield potential.In-parallel analysis of the QTL contributions under different nitrogen treatments or heading periods confirmed the significant effect of ipa1-2D in increasing stem diameter,panicle primary branch number,and spikelet number per panicle.We proved that the two individual QTLs had a stable effect in increasing the yield potential but com-peted to decrease the panicle secondary branch number,panicle number,and yield potential when they were pyr-amided.This work provides a full view of the plasticity of two QTLs in shaping yield-related traits and lays the foundation for the rational design of rice breeding in the future.

Adverse Pregnancy Outcomes Following Cryotherapy, Thermal Ablation, and Loop Electrosurgical Excision Procedure for Cervical Treatments among Reproductive Age Women in Zambia

Background: Cervical Intraepithelial neoplasia treatments have become essential interventions to manage cervical lesions. Most recipients are women of reproductive age who, as reported in the literature, may be at risk of adverse pregnancy outcomes. This study investigated the risk of abortions, prematurity, stillbirths, and prolonged labor among reproductive-age women following Cryotherapy, Thermal ablation, and Loop Electrosurgical Excision Procedure treatments in Zambia. Methods: This cross-sectional study analyzed records of 8000 women aged 15 - 49 years at the Adult Infectious Disease Control Centre using records between January 2010 and December 2020. Women constituting the treatment group were all respondents treated by cryotherapy, thermal ablation, and LEEP, while the control group were VIA negative women. Women from both groups were invited to answer a phone survey. Data were analyzed using Stata version 16;descriptive analysis estimated the prevalence and obtained the frequency distribution of abortion, prematurity, prolonged labor and fresh stillbiths. Chi-square and Fisher’s exact test established the associations of CIN and APOs at 95% Confidence intervals. Univariate and multivariable binary logistic regression estimated the odds of adverse pregnancy outcomes across the three treatments. Results: Adverse pregnancy outcomes were more prevalent in the treatment group (39.2%) compared to the untreated group (16.9%). Across the two groups, normal outcomes were lower in the treated (42.3% vs 57.7%). The treated group accounted for the majority of abortions (74.5% vs 25.5%) and prolonged labor (72.5% vs 27.5%), while the untreated group accounted for higher proportions of stillbirths (66.7% vs 33.3%) and prematurity (53% vs 47%). Adverse pregnancy outcomes were five and two times more likely in women treated with thermal ablation (aOR = 5.05, 95% CI = 4.01 - 6.36, p Conclusion: Cervical treatment among Zambian women increases the risk of abortion and prolongs labor. Therefore, caution should be taken when administered to those of reproductive age. Vigilant monitoring should be maintained during pregnancy, delivery, and postpartum to improve maternal and neonatal health.

Effects of silvicultural treatments on mechanical properties of Pinus sylvestris var.mongolica plantations

A study was conducted to determine the influences of initial planting densities, thinning intensities, exposures and slope sites on physical property （wood density） and mechanical properties such as modulus of elasticity （MOE）, bending strength, impact strength, compression strength along grain and hardness） of Pinus sylvestris var. mongolica plantation in Mao＇ershan Forest Farm, Northeast China. Results show that the different initial planting densities （1.5 m×1.0 m, 1.5 m×2.0 m and 1.5 m×2.5 m） had significant effects on wood density and MOE, and the highest mean wood density and indexes of mechanical properties occurred in the stand with an initial planting density of 1.5 m×1.0 m. The indexes of mechanical properties such as hardness of end, bending strength, MOE and compression strength along grain of wood increased after mild thinning, but decreased after violent thinning. The exposures （sunny slope and shady slope） had a significant effect on MOE, and the highest mean MOE occurred on sunny slope. The slope sites （upper site and lower site） had a significant effect on wood density and main mechanical properties, except hardness. The highest mean wood density and mechanical properties occurred at lower site.

Effects of Different Treatments on Seed Germination of Gagea nigra

According to different mechanisms of dormancy,seeds of Gagea nigra L.Z.Shue were treated with different methods so as to investigate the effects of different treatments on seed germination of G.nigra.The results showed that at 4 ℃,the seeds of G.nigra began to germinate on day 32 with germination period of 80 d and germination rate of 72%;room temperature（25 ℃） and acid and alkali treatments were all unsuitable for the germination of G.nigra seeds;no significant differences were found in germination rate of G.nigra seeds among warm water（50℃）,ultrasound and 200 mg/L GA_3treatments（P 0.05）;seed coat-removing treatment effectively promoted the germination of G.nigra seeds（P =0.002 0.01） with germination rate of 88%;seed coat piercing ＋ 200 mg/L GA_3 and 500 mg/L GA_3＋15% H_2O_2 treatments effectively promoted the germination of G.nigra seeds with germination rates of 84% and 82%,respectively（P0.05）;the germination vigor of G.nigra seeds in the seed coat piercing ＋ 200 mg/L GA_3 treatment was highest,and it was significantly higher than those in the other treatments.

Effects of Different Fertilization Treatments on Biological Activity of Reclaimed Soil

As per randomized block design, the research had different fertilizer treatments, and the organic matter, respiration, enzyme activity and microbial carbon and nitrogen in reclaimed soil were studied. Fertilization schemes were as follows： The treatment without fertilizers（CK）, the treatment with chemical fertilizers（C）, the treatment with chemical fertilizers and bacterial fertilizer（CB）, the treatment with organic fertilizer and chemical fertilizers（CM）, and the treatment with chemical fertilizers, organic fertilizer and bacterial fertilizer（CMB）. The results showed： Four fertilization treatments could improve the content of soil organic matter. CMB, CM and CB could significantly improve the soil respiration. Organic fertilizer and fertilizer could significantly improve soil enzyme activity, In different growth stages the CMB treatment had highest urease and phosphatase.The most significant in the treatment content of sucrose was CM. Organic fertilizer and microbial fertilizer can significantly improve the microbial carbon and nitrogen in soil. For the microbial biomass carbon, the CMB treatment increased by 11%-34% than CB treatment, and 35%-63% than C treatment. In terms of microbial nitrogen CMB, CM respectively increased by 31%-51% than CB treatment, and 52%-100% compared with C. In the process of land reclamation, we should combine the organic fertilizer, microbial fertilizer and inorganic fertilizer. Only in this way can soil biological activity be accelerated, soil microbial environment improved, and the ripening increased soil nutrient and soil cultivation be enhanced.

Influence of thermomechanical treatments on localized corrosion susceptibility and propagation mechanism of AA2099 Al-Li alloy

In order to manifest the influence of specific microstructural component on the development of severe localized corrosion in an AA2099 aluminum-lithium alloy, the corrosion behavior of the alloy subjected to solution heat treatment, cold working and artificial ageing was investigated. Immersion testing and potentiodynamic polarization were employed to introduce localized corrosion; scanning electron microscopy and transmission electron microscopy were used to characterize the alloy microstructure and corrosion morphology. It was found that the susceptibility of the alloy to severe localized corrosion was sensitive to thermomechanical treatments. Additionally, the state of alloying elements influenced the mechanism of localized corrosion propagation. Specifically, the alloy in T8 conditions showed higher susceptibility to severe localized corrosion than that in other conditions. During potentiodynamic polarization, the alloy in solution heat-treated and T3 conditions displayed crystallographic corrosion morphology while the alloy in T6 and T8 conditions exhibited selective attack of grain interiors and grain boundaries in local regions.

Microstructure and properties of Cu-2.3Fe-0.03P alloy during thermomechanical treatments

A short process without solution treatment was developed to manufacture Cu-2.3Fe-0.03 P alloy strips. After hot rolling-quenching and cold rolling with 80% reduction, the alloy exhibited excellent resistance to recrystallization softening. The hardness and electrical conductivity of Cu-Fe-P alloy under different thermomechanical treatments were measured by hardness tester and double bridge tester, respectively, and the microstructure of the alloy was examined by optical microscopy and transmission electron microscopy. The results show that the finished product of Cu-2.3Fe-0.03 P alloy was strengthened by work hardening, while the Fe precipitates with the size of about 25 nm stabilized the cold rolled structure. The conductivity decreased during cold rolling, especially for the pre-aged specimens, because the fine precipitates with the size smaller than 5 nm re-dissolved easily into the matrix. A Cu-Fe-P alloy with an electrical conductivity of 66% IACS and a hardness of HV 134 can be gained.

Stress Treatments and DNA Methylation Affected the Somatic Embryogenesis of Citrus Callus

The evaluation on the callus embryogenesis capacity of 15 genotypes of citrus showed that stress treatments were conducive to somatic embryogenesis and could enhance the recovery of the missed capacity of embryogenesis for some genotypes. Randomly amplified polymorphic DNA (RAPD) and methylation sensitive amplified polymorphism (MSAP) analysis indicated that there existed significant differences in DNA methylation status between the callus capable of producing somatic embryoids and that which missed the embryogenesis capacity of the same genotype Newhall navel orange ( Citrus sinensis Osb. cv. Newhall). The DNA methylation level of the former was lower than that of the latter. However, RAPD profiles did not show any difference between these two kinds of callus.

Effects of Peracetic Acid(PAA) Combined with Calcium Treatments on Storage Quality of Loquat Fruit

[Objective] The paper was to evaluate effects of peracetic acid （PAA） combined with calcium treatments on storage quality of Ioquat fruits, so as to pro- vide practical techniques to solve the problems of postharvest rot and quality deteri- oration for Ioquat fruits. [Method] With Ioquat fruits of Qingzhong variety as materi- als, 0.2%, 0.4% and 0.8% PAA combined with 0.8% CaCI2 was used to soak Ioquat fruits for 4 min, 0.8% CaCl2 and water treatments were set as two controls; the fruits were dried and packaged by 0.02 mm PE bags, then stored under non-chilling low temperature of （7±1） ℃. The indicators related to storage quality of Ioquat fruits were randomly tested once every 3 d, and their variation situations were analyzed. [Result] Compared with two control treatments and 0.2% PAA, 0.8% PAA combined with calcium treatments, the treatment of 0.4% PAA combined with 0.8% CaCl2 could significantly inhibit rot index, weight loss rate, firmness and cell membrane permeability of Ioquat fruits during storage period, which could also effectively delay the reduction of titratable acid, vitamin C, soluble solid content and juice yield, and maintain respiration intensity of fruits at a low level; the appearance and flavor qual- ity of fruits were good after stored for 25 d. [Conclusion] 0.4% PAA combined with 0.8% CaCl2 treatment is an efficient, safe and economical practice technology in an- ti-corrosion and quality preservation for postharvest Ioquat fruits .

Effect of alkali treatments on apatite formation of microarc-oxidized coating on titanium alloy surface

Alkali treatments with three concentrations were used to modify a microarc-oxidized(MAO) coating on titanium alloy surface in order to further improve its surface bioactivity. Morphology, chemical compositions and phase constitues, roughness, contact angle and apatite induction of the alkali-treated coatings were studied and compared. Scanning electron microscope(SEM) was applied to observe the morphologies, X-ray diffraction(XRD) and X-ray photoelectron spectroscopy(XPS) were used to detect the phase constitutes and chemical compositions, a surface topography profilometer was used to analyze the surface roughness, and contact angle was measured by liquid drop method. Alkali treatements result in the formation of Na2Ti6O13 and Na2Ti3O7 phase on the MAO coating, which leads to the increase of surface roughness and the decrease of contact angle. Experimental results showed that the apatite induction of the alkali-treated coatings was dependent on the applied alkali concentrations during treatments, and Na+concentration can promote the formation of apatite phase.

Investigation of cost-effectiveness of highway asphalt pavement maintenance treatments based on rutting development analysis

To investigate the cost-effectiveness of different maintenance treatments of highways in Jiangsu Province, the historical pavement maintenance records, traffic load information and pavement performance data in the pavement management system （PMS） are recorded and analyzed. Compared with the growth model, the linear model, the logarithm model and the exponential model, the cubic model has higher regression accuracy R2 and it can capture the sigmoid shape of the deterioration curve. So it is selected to simulate the pavement rotting development. The benefit over cost ratio is calculated to quantify the treatment cost- effectiveness. The analysis results show that thin hot mix asphalt （HMA） overlays and micro surfacing are more cost- effective than the. other two treatments on light and moderate traffic roads. Hot in-place recycling and thick HMA overlays have much longer service lives and greater cost-effectiveness under heavy or extra heavy traffic.

Effect of high temperature treatments on microstructure of Nb-Ti-Cr-Si based ultrahigh temperature alloy

To investigate the effects of homogenizing and aging treatments on the microstructure of an Nb-Ti-Cr-Si based ultrahigh temperature alloy,coupons were homogenized at 1 200-1 500 °C for 24 h,and then aged at 1 000 °C for 24 h.The results show that the heat-treated alloy is composed of Nb solid solution（Nbss）,（Nb,X）5Si3 and Cr2Nb phases.With the increase of heat-treatment temperature,previous Nbss dendrites transformed into equiaxed grains,and petal-like Nbss/（Nb,X）5Si3 eutectic colonies gradually changed into small（Nb,X）5Si3 particles distributed in Nbss matrix.A drastic change occurred in the morphology of the Laves phase after homogenizing treatment.Previously coarse Cr2Nb blocks dissolved during homogenizing at temperature above 1 300 °C,and then much finer and crowded Cr2Nb flakes precipitated in the Nbss matrix in cooling.Aging treatment at 1 000 °C for 24 h led to further precipitation of fine particles of Laves phase in Nbss matrix and made the difference in concentrations of Ti,Hf and Al in Nbss,（Nb,X）5Si3 and Cr2Nb phases reduced.

Effects of Nitrogen Treatments on Organic Carbon Mineralization of Citrus Orchard Soil

[Objective] This study aimed to investigate the effect of soil organic carbon mineralization at different temperature on the amount of nitrogen application, in order to provide references for the establishment of carbon circulation model for orchard eco-system. [Method] The effects of nitrogen treatments on soil organic carbon mineralization of citrus orchard soil were investigated under 10, 20, 30 ℃ by laboratory simulated experiment. [Result] The mineralization rate decreased quickly at the be- ginning of the experiment but remained stable at the late period under three temper- ature treatments. The amounts of CO2 ranged from 1 328.25-2 219.42 mg/kg under three temperature condition, and the amount of soil organic carbon mineralization of 100 mg/kg （N4） treatment was the greatest, while that of CK was the lowest. High level nitrogen treatment （N4 and N3） were significant higher than the lower level nitro- gen treatment （N2 and N1）. The soil organic carbon mineralization rate increased with the temperature from 10 to 30℃. The dependence of soil carbon mineralization to temperature （Q10） was different under different nitrogen treatments that the Qlo value of N2 treatment was the lowest while that of the N4 treatment was the greatest. The soil organic carbon mineralization in Citrus orange orchard soil was affected significantly by high level nitrogen treatment, but with no significance under lower nitrogen treatment. [Conclusion] The dependence of soil carbon mineralization to temperature （Q10） increased with the increasing nitrogen input. The combination of nitrogen with temperature may increase the CO2 emission from Citrus orchard soil.

Effects of mother tree ages, different rooting mediums, light conditions and auxin treatments on rooting behaviour of Dalbergia sissoo branch cuttings

Dalbergia sissoo Roxb. is one of the promising multipurpose tree species of South Asia. Most of the plantations of D. sissoo from seeds are facing severe threats due to the die-back disease, which ultimately causes death of this potential tree-species within a few months. Vegetative propagation could avoid the die-back disease. Thirty mother trees of different age-groups of D. sissoo were selected for evaluating the rooting behaviour of branch cuttings from D. sissoo as influenced by auxins （IAA or IBA at 100, 200, 500 mg·L^-1）, ages of mother trees （10, 4 and 2 years old） and different environment conditions, i.e., different mediums （soil and sand） or light conditions （in shade and open condition）. The results show that application of IAA and IBA induced more numbers of cuttings （collected from 10-year-old mother trees） to root compared to control. Branch cuttings of D. sissoo collected from 10-year-old mother trees and planted in soil bed in open conditions had 100.0% of cuttings to root in IAA （100 mg·L^-1） and IBA （200 mg·L^-1） treatments. Both rooting medium （Soil and sand） influenced significantly （p〈0.05） on rooting response of branch cuttings. Soil medium was found to achieve maximum no. of branch cuttings to root, compared to sand medium.

Effects of RRA Treatments on Microstructures and Properties of a New High-strength Aluminum-Lithium Alloy-2A97

A new high strength 2A97 Al-Cu-Li-X alloy was subjected to triple-aging of retrogression and re-aging treatments （RRA）. Transmission electron microscopy （TEM）, differential scanning calorimetry （DSC）, and tensile tests were used to investigate the effects of RRA treatment on the microstructures and properties. DSC test reveals the reversion temperature range of the strengthening δ＇ （Al3Li） phase. The results show that the microstructure consists of δ＇ （Al3Li） phase, T1 （Al2CuLi） phase and θ″/θ′（Al2Cu） phase for 2A97 alloy treated by a triple-aging of a retrogression and re-aging treatment in the following order： （1） at 165℃×30 min, （2） at 220 ℃ or 240℃ × 15 min, （3） at 165℃×24 h. The plastic deformation, incorporated into the treatment after secondary high temperature aging, promotes the T1 precipitation during final re-aging. The tensile properties of the alloy treated by the retrogression and re-aging treatment reach the peak level of alloy single-aged at 165℃ in T6 temper.

Efficacy of capecitabine and oxaliplatin regimen for extrahepatic metastasis of hepatocellular carcinoma following local treatments

AIM: To investigate the efficacy and safety of capecitabine and oxaliplatin (CapeOx) for extrahepatic metastasis after local treatment of hepatocellular carcinoma (HCC). METHODS: Thirty-two patients with extrahepatic metastasis of HCC after local treatment were prospectively enrolled. The CapeOx regimen consisted of capecitabine 1000 mg/m 2 taken orally twice daily on days 1-14, and oxaliplatin was administered at a total dose of 100 mg/m 2 on day 1. The treatment was repeated every 3 wk until disease progression or unaccetablle toxicity. Efficacy and safety were assessable for all enrolled patients. The primary objective of this study was to assess the overall response rate. The secondary objectives were to evaluate the overall survival (OS), the time to tumor progression (TTP) and the toxicity profile of the combined strategy. TTP and OS were assessed by the Kaplan-Meier method and differences between the curves were analyzed using the log-rank test. The statistical software SPSS version 15.0 for Windows (SPSS Inc., Chicago, IL, United States) was used for statistical analysis. All P values were 2-tailed, with statistical significance defined byP ≤ 0.05. RESULTS: Thirty-two patients were assessable for efficacy and toxicity. The median follow-up duration was 15 mo (range, 12-20 mo). At the cut-off date of March 31, 2012, 27 patients died due to tumor progression and one patient died of myocardial infarction. Four patients were still alive (three patients with disease progression). OR was 21.9% (n = 7), the stabilization rate was 40.6% (n = 13), and the disease control rate was 62.5%. The responses lasted from 4 to 19 mo (median, 6 mo). Median TTP was 4.2 mo (95%CI: 2.5-7.4), and the median OS time was 9.2 mo (95%CI: 6.5-17.8). The 1-year survival rate was 43.6% (95%CI: 29.0-66.0). In a multivariate analysis, OS was significantly longer in patients with a Child-Pugh class A compared with class B patients (P = 0.014), with a median OS of 10.1 mo vs 5.4 mo, and there were trends towards longer OS (P = 0.065) in patients without portal vein tumor thrombosis. There were no significant effects of age, gender, performance status, cirrhosis, metastatic sites, and level of alpha fetoprotein (AFP) or hepatitis B virus-DNA on OS. Among the 22 patients with elevated AFP levels at baseline (≥ 400 ng/mL), the level fell by more than 50% during treatment in 6 patients (27.3%). The most frequent treatment-related grade 3 to 4 toxicities included leucopenia/neutropenia, transient elevation of aminotransferases, handfoot syndrome and fatigue. CONCLUSION: CapeOx showed modest anti-tumor activity in metastatic HCC. However, the manageable toxicity profile and the encouraging disease control rate deserve further study for these patients.

Effect of pre-sowing treatments on germination and initial seedling development of Albizia saman in the nursery

Albizia saman （Jacq.） F. Muell. commonly known as rain tree seeds were treated with five pre-sowing treatments to study the effect of pre-sowing treatments on germination and initial seedling development in the nursery.The experiment was established in the nursery of the Institute of Forestry and Environmental Sciences.University of Chittagong, Chittagong, Bangladesh. Results revealed that Nail clipping in one side of the seed （at the distal end of the seed） （T4） provides the highest （50%） seed germination. The second highest germination （42%） was obtained for the seeds treated with immersion in cold water for 24 h （T1）. Germination was completely inhibited when the seeds immersed in boiled water for 30 s followed in cold water soaking for 24 h. Other germination parameter and initial morphological growth and biomass production of the seedlings was also higher for the treatments T4and Ti in comparison to the control （Ta）treatment. Pre-sowing treatments of T4 e.g. Nail clipping in one side of the seed （at the distal end of the seed） and T1 （Seeds immersed in cold water for 24 h） may be recommended for maximum germination and initial vigorous seedlings growth of Albizia sarnan in the nursery.
