Wild cabbages and the effects of cultivation

Journal of Genetics - The wild cabbage,Brassica oleracea L., on the coasts of western Europe, shows enormous increase in size when taken into cultivation. It shows much variation, which is...     

Enhancement of trace-element content of cabbages grown in urban areas

Summary Significantly higher contents of boron, molybdenum and zinc were observed in cabbages in urban than in rural areas. The levels of extractable boron, copper, lead, nickel and zinc were markedly enhanced in the urban soils but there was no corresponding enhancement of the levels of copper, lead and nickel in the cabbages.     

有机污染物芘胁迫下白菜生理特性变化规律

为探究多环芳烃芘对白菜生理特性的影响,通过盆栽实验对华北地区常见的11种白菜进行不同浓度芘胁迫下的培养,研究白菜生理指标的变化规律。结果表明：白菜的种类和芘的浓度对白菜生理指标（生物量、丙二醛、叶绿素）均有显著影响,且随芘浓度变化,不同种类白菜的生理指标呈现不同的变化规律。白菜的生物量随芘的添加呈现两种变化：一是随芘添加浓度增加白菜生物量逐渐下降;二是在中低浓度芘（5、15、45 mg/kg）处理白菜生物量升高,高浓度（135、405 mg/kg）胁迫下生物量下降。白菜的丙二醛（MDA）含量随芘浓度的增加,表现出3种不同规律：各浓度之间均无显著性差异,MDA含量逐渐升高,以及显著低于对照组。叶绿素含量随芘浓度的增加,主要呈现出先下降后上升和逐渐上升2种变化趋势。京春白（JCB）和中白50（ZB-50）对芘的胁迫具有良好的耐受性,生理指标变化较小;中浓度芘胁迫下京翠60（JC-60）和京春绿（JCL）较为敏感,高浓度下京秋65（JQ-65）和吉红308（JH-308）生理指标变化显著,可以作为中低浓度和高浓度芘污染土壤指示作物。     

The performance of Brevicoryne brassicae on ornamental cabbages grown in CO2-enriched atmospheres

The effect of different atmospheric CO₂ concentrations on life table parameters and the biology of the cabbage aphid, Brevicoryne brassicae, when fed on two cultivars of ornamental cabbage, was studied in a greenhouse designed for CO₂ studies. Aphid performance was influenced by increasing atmospheric CO₂ levels, significantly affecting the intrinsic rate of increase (r_m), finite rate of increase (λ), mean generation time (T), doubling time (DT), and pre-reproductive period. The longest pre-reproductive period was observed for aphids grown at 380 ppm CO₂. The intrinsic rate of natural increase was highest for aphids at 1050 ppm CO₂, because of their faster development, high daily rate of progeny production, and higher survivorship. Future elevated CO₂ concentrations will enhance aphid population outbreaks and consequently increase the damage caused.     

A Biological Stone from a Medieval Cemetery in Poland

A review of the literature shows that origination of biological stones as well as their pathogenesis mostly depend on the environmental factors. As a result, the structural spectrum of such calculi and their chemical composition are highly diversified. It is well known that biological stones are formed mostly in the digestive and urinary tracts. However, it has been demonstrated that this kind of stony structure can be also, though rarely, found in circulatory and reproductive systems, skin, mucosa, and tear ducts. Although in palaeopathology, the list of biological stones is enriched by stony tumours and/or discharges, it is very difficult to uncover the small size deposits in excavation material. In the literature such findings, originating from different countries and centuries, are few. The described stone was found among the bones of an adult individual in the medieval cemetery of Gdańsk (Poland). The SEM, X-ray spectrometer and chemical evaluation revealed that it was a bladder calculus.     

Changes in the radical-scavenging activity of sliced red and green cabbages during storage

Vegetables are rich source of antioxidative components such as ascorbic acid and polyphenols, which scavenge free radicals and reactive oxygen species and prevent life-style related diseases. In this work, the changes of radical-scavenging activity in shredded red and green cabbage leaves during storage were determined as well as ascorbic acid and polyphenol contents. Shredded cabbage leaves were stored at 10 degrees C for 7 days in the presence or absence of oxygen. Radical-scavenging activity, ascorbic acid content, and polyphenol content of shredded cabbage leaves remained for 7 days in the presence and absence of oxygen. These results demonstrate that the radical-scavenging activity, ascorbic acid, and polyphenols are stable in shredded cabbage leaves and that oxygen does not affect the activity and active components.     

纱帽山滇文化墓地颅骨的人类学特征

镉胁迫对不同甘蓝基因型光合特性和养分吸收的影响

以2个耐镉(Cd)性不同的甘蓝品种为材料,研究了不同Cd浓度(0、20、50、100μmol.L-1)对甘蓝植株生长、叶片光合特性和养分吸收的影响.结果表明:Cd敏感品种在低浓度Cd(20μmol.L-1)处理下生长受到明显抑制,叶片净光合速率(Pn)、气孔导度(Gs)、PSⅡ光化学效率(Fv/Fm)、PSⅡ光合电子传递量子效率(ΦPSⅡ)及地上部、根系干质量显著降低;Cd耐性品种在高浓度Cd(50和100μmol.L-1)处理下生长和光合特性受到显著影响;Cd胁迫降低了甘蓝叶片叶绿素a和b含量,尤其对叶绿素a的影响较大,进而抑制了叶片光合能力.Cd胁迫显著降低了植株对Mn的吸收,抑制了Mg和Fe从根部向地上部的转运,且Cd敏感品种受抑制幅度更大;Cd胁迫促进了Cd耐性品种对P和S的吸收,而Cd敏感品种相反.因此,Cd胁迫下甘蓝敏感品种叶片Mn、Fe、Mg、S和P含量的降低是影响其叶片光合作用,进而抑制植株生长的重要生理原因.     

新疆喀什下坂地墓地青铜时代人群颅骨的测量性状

下坂地墓地青铜时代居民是帕米尔高原区早期人群的代表。通过颅骨测量性状特征对该人群来源和流向问题的讨论,为建立欧亚大陆青铜时代人群的流动、变迁史提供了新的素材。与欧亚大陆青铜时代时空相关人群对比分析的结果表明,下坂地青铜组居民的祖先人群,可能是来自东欧南部草原地带的洞室墓文化居民。他们在安德罗诺沃文化的繁盛期,自东欧草原地带迁徙到帕米尔高原区,逐渐发展为安德罗诺沃文化的一个地方变体。     

Bicoronal synostosis in a child from historic Omaha Cemetery 25DK10

Fragmentary cranial remains of a child from a commingled burial in a historic Omaha Cemetery (AD 1780–1800) exhibit bony fusion between the frontal, parietals, and sphenoid. The child's remains are consistent with a developmental age between newborn and 6 months postnatal. Radiological and morphological analyses confirm that this individual exhibits osteological signs pathognomic of bicoronal sutural synostosis, including deformation of the lateral orbital margin. This case, although fragmentary, significantly augments other archaeological cases of coronal synostosis reported in the literature. In addition, an extremely large bregmatic fontanel, expanded anterior cranial fossa, and bossed forehead compared with undeformed individuals suggest the child also suffered from increased intracranial pressure perhaps related to an associated hydrocephaly. Despite the deformity, the remains of this child were treated in much the same manner as other infant remains from the site, including the presence of red mercury pigment on the skeletal remains.

Dental health of elderly confederate veterans: evidence from the Texas State Cemetery

Analysis of the skeletal remains of 50 Confederate veterans provided a unique opportunity to explore the dental health of a geriatric sample. These men, who died between 1907-1932, had an average age at death of 76.7 years. Ninety percent were institutionalized at the Confederate Home for Men (Austin, TX) prior to their deaths. This elderly sample was assessed in terms of caries, antemortem tooth loss (AMTL), abscesses, and linear enamel hypoplasias. On a per tooth basis, the AMTL rate was 57.2%. Of 39 dentate men, 33 (84.6%) had dental caries, and 24.4% (121 of 496) of teeth were carious. Ten (25.0%) of the dentate men had hypoplastic teeth. At least one abscess was seen in 14 (28%) of 50 individuals. Results from this geriatric institutionalized sample are compared to contemporaneous historical samples. Disparities in dental health among these groups may be due to differences in average age at death, and these comparisons allow a better understanding of dental changes that occur with age. The sample is also compared to modern elderly samples: modern groups have higher caries rates, possibly because they retained more teeth. This finding may be due in part to diets in the United States becoming increasingly cariogenic over time. In addition, dental care has moved from the reactive practices seen in the nineteenth and early twentieth centuries (such as tooth extractions) to modern proactive solutions dedicated to preserving and restoring teeth (such as tooth brushing, fluoride treatments, and dental fillings).     

Social implications of mortality patterns of juveniles from Poundbury Camp, Romano-British Cemetery

Attempts have been made to reconstruct the Romano-British population that was buried at Poundbury Camp, Dorchester, England. Over 1400 graves were excavated and about 1200 skeletons of adults and juveniles were recovered, dating from the 1st to the 5th Centuries AD. The burial patterns indicate that the family was the important unit in the community that was served by Poundbury Camp. The newborn but perhaps not the stillborn were buried in the cemetery. Infanticide was not practised. Infant mortality was high and weaning may have been at a very early age. There were relatively few children and family sizes must have been small. Among the adolescents there were three times as many girls as boys. This is interpreted as a consequence of the materialism of a society with an agrarian economy.
