Abstract	Okra an important vegetable crop is fairly high in vitamins and minerals and is eaten raw and present in everyday dishes of Vietnam. Nowadays, organic farming is a trend which fetches higher value for farmers while is also safe from chemical fertilizers and pesticides. Organic cultivation of okra though cow dung is yet to be explored before adoption. The field experiment was conducted in the winter-spring season of 2020 at Huong An commune, Huong Tra town, Central Vietnam to investigate the effects of levels of compost made from cow dung on the growth, yield of okra plants and soil property. Five different doses of cow dung compost (0, 2, 4. 6, 8 tons/ha) were applied to the soil. Growth, yield components and yield were investigated. The results indicated that cow dung compost had a positive effect on the growth and yield of okra. The application of 6 and 8 tons of cow dung compost recorded the highest pod yields of 6.5 and 6.6 tons/ha, respectively. The soils decomposed with cow dung compost resulted in increased organic matter content thus improving the soil physical and chemical properties. Cow dung compost may be recommended to farmers for organic okra production.

Abstract	Degradation of tropical forests is a major driver of the global extinction crisis. A key question is understanding the role of evolution history during forest succession in the context of forest restoration for maintaining ecosystem function and stability. This study was conducted in a fragmented forest landscape in the central highlands of Vietnam. We sampled living trees with diameters at breast height of ≥6.0 cm in nineteen 0.25 ha plots to evaluate forest community structure changes over two early successional stages (<10 years and 10–20 years old) after abandonment and old-growth. We used both statistically metric and nonmetric analyses to examine correlations of community composition during successional stages and along elevational gradients. We found that (i) significant differences existed in the structural compositions between early successional forests and old-growth forests, but did not exist within early successional forests; (ii) the phylogenetic structure shifted from overdispersion to clustering with increasing successional ages; and (iii) above-ground biomass (AGB), representing ecosystem functioning, significantly increased from early-to-late successional stages, but did not correlate with phylogenetic diversity or elevation. Our results revealed that the forest community structure was strongly affected by degradation, particularly AGB and phylogenetic structure. These findings have clear implications for sustaining biodiversity persistence and ecosystem functioning in human-modified landscapes in the study region.

Abstract	In Japan, rice straw (RS) is commonly incorporated into the soil after harvest to maintain the fertility of paddy soil. However, in mixed crop–livestock systems, RS is collected to feed livestock and then cow dung compost (CDC) is applied to the fields. We found in previous research that CDC supplied more N to the fields than RS, but the soil total N and available N of fields to which CDC was applied were similar to those receiving conventional RS application. To identify the reason for this result, we investigated the N inputs (organic matter, fertilizer, N fixation), N outputs (plant N uptake, N leaching loss), and the N balance of RS application (RS treatment) and RS removal plus CDC application (CDC treatment) in 10 neighboring paddy field pairs in Mamurogawa town, Yamagata Prefecture, Japan. The N fertilizer contributed the highest percentage to total N input, followed by organic matter and N fixation. The amounts of N fertilizer and N fixation in the RS treatment were similar to those in the CDC treatment. CDC contributed significantly more N to the fields than RS, but the total N input was similar between treatments. The N output from plant N uptake and leaching loss were higher in the CDC treatment than the RS treatment, but the difference was not significant. Plant N uptake was the main N output, accounting for 98% of total N output. The N balance was positive and similar between treatments. Therefore, the non-significant differences in total N input, total N output, and N balance between treatments explain the similarity in soil total N and available N.

Abstract	Rice straw (RS) and cow dung compost (CDC) are good sources of phosphorus (P) to support rice production. Our previous research found that CDC application in mixed crop-livestock systems supplied more total P to the paddy soil than RS, but available P did not differ significantly between the CDC and RS fields. To explain these results, we investigated the soil total P and soil P balance in RS and CDC fields. From the 79 paddy fields managed by farmers in Mamurogawa, Yamagata, Japan, which were investigated in previous research, we selected 10 pairs of adjacent RS and CDC fields, then measured soil total P, P inputs (RS or CDC and fertilizer), and P outputs (plant uptake and leaching), and calculated the resulting soil P balance. The result showed that soil total P did not differ significantly between treatments. The higher P input from CDC would let farmers apply less fertilizer P in CDC fields than in RS fields, but there was no significant difference in total P input between treatments. Plant P uptake and leaching did not differ significantly between treatments. The soil P balance was positive (i.e., net P accumulation) and did not differ significantly between treatments. The lack of differences in the total P input, total P output, and soil P balance between treatments explains the non-significant differences in soil total P and available P.

Abstract	After the rice harvest in Japan, rice straw (RS) is usually cut by combine harvester and incorporated into the soil to improve its fertility. In mixed crop–livestock systems, however, RS is collected and used as livestock feed, and cow dung compost (CDC) is then applied to the soil. This system utilizes the residual organic matter from both rice production and livestock husbandry to make each product. CDC application is also considered to improve the fertility of paddy soil. However, the nutrient input from CDC and the effect of CDC application on soil fertility vary among regions and/or soil types. We compared soil fertility between RS application (RS treatment, avg. 32 years) and RS removal plus CDC application (CDC treatment, avg. 21 years) in 79 paddy fields in Mamurogawa town, Yamagata Prefecture, a cold temperate region of Japan, and measured the nutrient contents in the applied RS and CDC. The total C content of RS was significantly higher than that of CDC, whereas the N, P, K, and Si contents of CDC were significantly higher than those of RS. However, there was no significant difference in paddy soil fertility – as measured by soil organic C, total N, CEC, available N, P, and Si, exchangeable K, Ca, and Mg, base saturation percentage, pH, and bulk density – between the treatments. The soil fertility of most fields was adequate by RS or CDC treatment. Thus, leaving RS in paddy fields or removing it and then adding CDC to the paddy fields has a similar effect in maintaining adequate soil fertility for single rice production or rice–livestock production systems.

Abstract	Pneumorrhachis (PR) is an uncommon condition characterized by the accumulation of air within the spinal canal. This finding may occur due to various causes, mostly after trauma and medical procedures. It can manifest with various features depending on the underlying cause, the location, and the extent of the air trapped. Clinically, the symptoms in affected patients can span a spectrum, ranging from being asymptomatic to manifesting as radiculopathies resulting from compression. The pneumorrhachis-related cauda equina syndrome is incredibly rare and typically appears as a large volume of air causing compression or irritation of the nerve roots in the lower spinal cord. In this report, we present a female patient whose cauda equina syndrome developed as a result of accidental extradural pneumorrhachis after epidural injection in the lumbar spine.
