In evaluating certain process variables (homogenisation pressure, number of cycles and organic/aqueous phase relation), Tan and Nakajima (2005) produced β-carotene nanodispersions by solvent displacement method using Tween 20 as emulsifier, with mean diameters (D4,3) varying from 60 to 135 nm and with span values varying from 0.4 to 0.7. Ribeiro et al. (2008) used food grade materials, gelatin and Tween 20 to produce polymeric nanodispersions of β-carotene with mean diameters (D3,2) ranging from 74 to 77 nm. The dynamic light scattering analyses

also demonstrated that the bixin nanocapsules presented a buy GSK J4 monomodal distribution with a mean diameter (z-diameter) of 190 ± 9 nm and a polydispersity index of 0.098 ± 0.03. click here The PDI values ranging from 0.1 to 0.25 indicates a narrow size distribution while a PDI greater than 0.5 is related to a broad distribution ( Wu, Zhang, & Watanabe, 2011). Paese et al. (2009) produced nanocapsules with mean diameters (z-average) of 247 ± 4 nm and a polydispersity index lower than 0.2. Yuan et al. (2008), applied the technique of high pressure homogenisation and studied the influence of emulsifier type and concentration, homogenisation pressure, temperature and number of cycles, produced β-carotene nanoemulsions with

diameters ranging from 132 to 184 nm (determined by DLS). An unstable formulation of nanoparticles can form agglomerates and represent a risk to the health in the case of intravenous administration of a drug-loaded nanoparticle suspension, leading to blockage and embolism. The nanoparticle size control is a parameter that must be ensured during storage, since one form to verify if a nanoparticle formulation is physically stable is the periodic determination Dichloromethane dehalogenase of the mean

diameter (Wu et al., 2011). In the present work, no significant differences were observed (p < 0.05) between the volume-weighted diameters (D4.3) determined by number and volume (via LD) and the mean diameters (z-diameter) measured by DLS. The bixin nanocapsules were considered stable because they did not exhibit any evidence of coalescence, creaming or flocculation in either analysis (LD or DLS) over 119 days of storage at 25 °C. These mechanisms of emulsion instability may be verified by an increase in mean particle diameter because the particles are in continual motion and collide with one another under normal conditions. Silva et al. (2011) produced β-carotene nanoemulsions distributed in a monomodal profile with surface-weighted mean diameter (D3,2) of 9.24 ± 0.16 nm and 228.63 ± 0.01 nm. The authors verified the increase in the size of nanoemulsions in two formulations, which varied from 9.24 ± 0.16 to 94.

RMSECV was plotted against LVs to set the optimal number of LVs

RMSECV was plotted against LVs to set the optimal number of LVs. In order to identify anomalous samples (outliers) the leverage criterion and the Student residuals were used. The leverage criterion represents the influence of each sample Fasudil manufacturer in the regression model, with a threshold equal to 3 LV/n where n is the number of samples. The student residual indicates if the sample is within a normal distribution,

with a confidence level of 95%, assuming a threshold value of ±2.5. Afterwards, the models were tested to predict SSC and TA with validation set. The best calibration models were selected based on the highest correlation coefficient of validation (R  2) along with the lowest RMSECV and the lowest root mean square error of prediction (RMSEP). RMSEP was then expressed as RMSEP% corresponding to the percentage of error of prediction calculated with RMSEP divided by the mean values of measured quality parameters in fruits from the validation set ( Duarte, Barros, Delgadillo, Almeida, & Gil, 2002). equation(1) RMSEP=∑i=1nyi-yˆi2nwhere: yiyi = known

value; yˆi = calculated or predicted value and n = number of samples in the validation set. This value represents the average error that can be expected for the prediction of future samples, with a confidence interval of 95%. The general shapes of the spectra for the three fruit types were quite similar, though the spectra for the passion fruit showed weak absorption intensity and a slight displacement, possibly due to the thickness of the

skin (Fig. 1). The main absorption peaks coincided for all three fruits. selleck chemicals The peak at 1190 nm corresponds to the second and third C–H overtone regions, associated with sugar (Osborne, Fearn, & Hindle, 1993). The peak at 1500 nm overlaps with the first O–H overtone region related to organic acids (Roberts et al., 2004). In general, the absorbance patterns seen here can be loosely related to the functional groups associated with water and sugars. Indeed, most fruits contain 80–90% of water and show a rising sugar content throughout ripening. The spectra obtained here for apricot and tomato can be compared to other studies, apricot (Bureau et al., 2009) and tomato (Sirisomboon, 4��8C Tanaka, Kojima, & Williams, 2012). To the best of our knowledge, no study was published for passion fruit. The samples showed a large variability of SSC and TA for fruits of the three species used in this trial. These results confirm that selected fruits were in different ripening stages. Statistical analysis for the calibration and validation sample sets, i.e., data ranges, means, standard deviations (SD) and number of samples for SSC and TA are shown on Table 1. For fruits from the three different plant species used in this trial, different calibration models were calculated. The spectra pre-processing and the number of factors were both taken into consideration to determine the best models.

The objectives of these surveys are to: • measure the principal indicators of health status, medical practices during pregnancy and delivery, and perinatal risk factors; their changes from earlier national perinatal surveys, including similar surveys before 1995 [3], can thus be followed; The objective of this article is to describe the perinatal situation in 2010 in metropolitan France (oversea territories

excluded) and put it into perspective by looking at results from earlier surveys for the principal indicators of health, medical practices and risk levels. All four surveys followed the same protocol. Data collection covered all births during one week, that is, all liveborn or stillborn children, in public and private maternity units — as well as children born outside these institutions and subsequently transferred to one — at a gestational INCB018424 in vitro age of at least 22 weeks or weighing at least 500 g at birth. In 2010, maternity Ribociclib units with more than 2000 annual deliveries were allowed to spread data collection out over two weeks, by collecting data for all births

every other day [4]. The information came from three sources: an interview with women in the postpartum ward, to obtain information about their social and demographic characteristics and prenatal care, data from the medical files about complications of pregnancy and delivery and the child’s health status at birth, and another form completed by the head of the maternity unit describing its principal institutional characteristics. Several institutions were involved in these surveys. The general organisation and development of the questionnaire

were provided by the French national institute for health and medical research (Institut national de la santé et de la recherche médicale [Inserm U953]), and the Ministry of Health (the Directorate-General of Health [Direction générale de la santé] and the Direction of Research, Studies, Evaluation and Statistics [Direction de la recherche, des études, de l’évaluation et des statistiques, DREES]), as well as a scientific committee including representatives from district level Maternal and Child Health Services (physicians or midwives), directorates Buspirone HCl responsible for health care services and social services in the Ministry of Health, the French Institute for Public Health Surveillance (Institut de veille sanitaire), the regional and district social and health service bureaus (DRASS and DDASS), the regional health observatories (ORS), professional societies (anesthetists, midwives, obstetricians and pediatricians), and consumer groups. Inserm coordinated the study at the national level, and the Maternal and Child Health Services of most districts at the district level. Inserm produced the report that served as the basis of this article [4]; in addition, for the 2010 survey, the DREES drafted a report describing the characteristics and practices of the maternity units [5].

Ulery et al.

(1995) reported on the changes in soils in four large lysimeters filled with similar parent material over a 41 year period. The lysimeters were planted with monocultures of scrub oak (Quercus dumosa), chamise (Adenostoma fasiculatum), ceanothus (Ceanothus crassifolia), and Coulter pine (Pinus coulteri). As expected, the greatest N accumulation (to a 1 m depth) was under the N-fixing ceanothus (29 kg ha−1 yr−1), followed closely by oak (27 kg ha−1 yr−1), then chamise (15 kg ha−1 yr−1),and pine (10 kg ha−1 yr−1). The rates of N accretion under the non-fixing vegetation were not excessive compared to nearby measurements of inputs (23 kg ha−1 yr−1; Riggan et al. 1985), but increments in vegetation were not included in the study and thus total ecosystem increments could have been much greater than those reported. Bormann et al. (1993) reported on N increments over selleckchem a period of 5 years in a sandbox study at Hubbard Brook, New Hampshire, USA. In this study, excavated small plots were backfilled with find more sand obtained from a sand and gravel company to a depth of 1.3 m. Five cm of mixed topsoil were then added on top of the sand and tilled into

a depth of 20 cm. Soils were first sampled over one year after the topsoil was tilled in, at the time of planting of two N-fixers (Alnus glutinosa and Robinia pseudoacacia) and two pine species (Pinus resinosa and P. rigida). For this review, we report on the non-N-fixing species only. The authors reported unexplained N changes in vegetation + forest floor of 83 and 70 kg ha−1 yr−1 for Pinus resinosa and P. rigida, respectively, and concurrent changes in the 0–20 cm soils of −17 and −19 83 and 70 kg ha−1 yr−1, respectively. (Note that our calculations in Table 2 from their reported numbers differ slightly from these values.) Binkley et al. (2000) took issue with several aspects of this study, and concluded that the low precision precluded high confidence in the reported values. This prompted a response from Bormann et al. (2002) wherein they recalculated

their values, resulting in estimates of large increments of N in soil at the 20–135 cm depths (98 and 73 kg ha-1 yr-1 in P. resinosa and P. rigida, DNA ligase respectively) and less significant changes in estimates of vegetation and 0–20 cm soil changes. Bormann et al. (2002) concluded that they had very high confidence in their estimates of “unexplained” N accumulations. A rejoinder from Binkley (2002) expressed skepticism about the new calculations of unexplained soil N accumulations in the 20–135 cm depths. We will not take a position on that exchange, but merely report the numbers as part of the larger data set, noting the caveats described above. The case studies cited above give a very mixed picture of soil and ecosystem N accumulation.

niger produced a less polar metabolite, with an Rf value similar

niger produced a less polar metabolite, with an Rf value similar to that of ginsenoside Rh2 and compound K. This result suggests that the microbial conversion of ginsenoside Rb1 using A. niger KCCM 11239 induced the production of diverse PPD-type ginsenosides. We estimated that this result was induced by different types of β-glucosidase from Cobimetinib mouse A. niger KCCM 11239. Aspergillus species are known to produce different types of β-glucosidase. For example, Aspergillus sp. g48p produces two types of ginsenoside-hydrolyzing β-glucosidases: ginsenosidase type II hydrolyzes 20-O-glycosides of PPD-type ginsenosides and ginsenosidase type I hydrolyzes 3-O

and 20-O glycosides of PPD-type ginsenosides [25]. Sorafenib The enzymatic conversion of ginsenoside Rb1 over a time-course was conducted using a crude enzyme. Ginsenoside Rb1 was reacted with the same volume of crude enzyme for 48 h at 30°C and 50°C; the TLC results are shown in Fig. 2. When ginsenoside

Rb1 was reacted at 30°C, the levels of ginsenoside Rd were increased within 30 min and the levels of ginsenoside Rg3 were increased after 4 h. All of the ginsenoside Rb1 was converted to ginsenoside Rd and ginsenoside Rg3 after 24 h of incubation. Ginsenoside Rb1 was reacted with crude enzyme at 50°C to compare the effects of the reaction temperature. The results demonstrate that high reaction temperatures accelerate the reaction to produce ginsenoside Rg3. In addition, the conversion activity of A. niger after 48 h of a reaction time were compared by using three commercial enzymes ( Fig. 3). When ginsenoside Rb1 was reacted with Celluclast 1.5L and Cellulase 12T, the content of ginsenoside Rb1 was reduced and a productivity of Rd increased after 48 h. However, these enzymes were not converted further into active minor ginsenosides Rg3. In case of β-glucosidase from almond, ginsenoside hydrolyzing activity was not detected. Various products of Rb1 transformed by the crude enzyme isolated

from A. niger KCCM 11239 were confirmed via HPLC analysis. The profile of the reaction mixture of ginsenoside Rb1 at 30°C for 24 h of reaction is Pyruvate dehydrogenase lipoamide kinase isozyme 1 shown in Fig. 4. HPLC analysis yielded results similar to the findings of TLC. In addition, the amount of ginsenoside Rb1 was reduced with the extension of the reaction time, whereas other hydrolysis products including ginsenoside Rd and S-Rg3 increased after 24 h of incubation at 30°C. Ginsenoside Rb1 harbors four β-glucosidic linkages, including a 20-C, β-(1→6) and a 3-C, β-(1→2) linkage. Fig. 4 shows that a peak area of Rd in a sample increased after 8 h, but decreased after 24 h. In the meantime, ginsenoside Rg3 was detected in a 24 h-reaction mixture and a ratio of the peak area was approximately 48.5%. By contrast, ginsenoside Rb1 was not detected in a 24-h reaction mixture.

HepG2 cells were exposed to increasing concentrations (25–50 μM)

HepG2 cells were exposed to increasing concentrations (25–50 μM) of each ginsenoside for 48 h. Among them, treatment of ginsenoside-Rh2 (25 μM or 50 μM) for 48 h induced a significant growth inhibition in HepG2 human hepatocellular carcinoma (Fig. 2A). Also, a more significant dose-dependent growth inhibitory effect is observed in cervical carcinoma (HeLa) than in any other cancer cell lines tested—hepatoma (HepG2), prostate carcinoma (DU145),

and colon cancer (HCT116) cell lines—for 24 h treatment (Fig. 2B). As shown in Fig. 2, some cancer cells have differential sensitivity Olaparib nmr to ginsenoside-Rh2-induced apoptosis, raising questions regarding the specific mechanisms responsible for this sensitivity. Because

several recent reports have implicated the role of AMPK in preventing apoptosis in various cancer cell type [21] and [22], we examined the ability of ginsenoside-Rh2 to enhance AMPK activity in a variety of cancer cells. To measure AMPK activity, we used phospho-specific (Phospho-Thr172) antibody for AMPK. As shown in Fig. 3, treatment with ginsenoside-Rh2 25 or 50 μM for 4 h significantly induces AMPK activation in HepG2, DU145, and HCT116 cells, but not in HeLa cells. Because HeLa cells do not induce AMPK activation and Decitabine exhibit relatively more sensitivity to ginsenoside-Rh2-induced apoptosis (Fig. 2B), we examined the correlation with AMPK activity and cell death. The results show that pharmacological inhibition of AMPK, in the presence of the AMPK inhibitor (compound C), reduces cell viability in HepG2 cells. Reverse transcriptase The combined treatment of compound C with ginsenoside-Rh2 (25 μM) resulted in lower cell

viability than treatment with ginsenoside-Rh2 alone for the indicated periods. Apoptotic cells were assessed using MTT (Fig. 4A) and Hoechst 33342 staining (Fig. 4B). Additionally, it was shown through Western blot analysis that PARP cleavage was substantially increased in compound C-treated cells (Fig. 4C). Although ginsenoside-Rh2 treatment induces AMPK activation in HepG2 cells, it does not affect AMPK activity in HeLa cells, and thereby treatment with the AMPK inhibitor does not affect the degree of PARP cleavage (Fig. 4D). These results indicated that the AMPK signaling pathway is important in blocking ginsenoside-Rh2-induced apoptosis, and that AMPK plays a critical role as an antiapoptotic molecule. Recently, studies reported that AMPK is activated by reactive oxygen species (ROS) generation in various cell lines [27] and [28]. To investigate whether ginsenoside-Rh2 induces ROS production, and thereby affects AMPK activity, HepG2 cells were treated with 25 μM ginsenoside-Rh2 for 8 h, and ROS was then measured using flow cytometric analysis of DCFH-DA-stained cells. As shown in Fig. 5A, ginsenoside-Rh2 induces an increase in ROS level, and treatment of 10 μM NAC blocks ginsenoside-Rh2-induced ROS generation.

The infected partner had to be well enough

The infected partner had to be well enough Wnt inhibitor not to require immediate ART. The couples were randomised to have either immediate or delayed ART. Both groups received the same care including counselling on safe sex practices, free condoms, treatment for sexually transmitted infections and regular HIV testing. In May 2011, it had been announced that there had been 27 HIV transmissions in the delayed ART group (877 couples) compared to only 1 in the immediate ART group (886 couples), a 96% reduction. In these 28 cases, the HIV strain was linked to the partner. This is the first randomised clinical trial to show that treating an HIV-infected individual

with ART can reduce the risk of HIV transmission to an uninfected partner. Even with “safer-sex” counselling,

there were 60 pregnancies in the delayed ART group, despite that group having more incentive for safer-sex. Following the announcement of this result, all infected participants were offered ART. Myron reported the 10th annual review of this study. In the delayed ART group, there had been a total of 28 cases BMS-754807 supplier of HIV transmission with the HIV strain linked to the partner and 11 cases of unlinked transmission. In the one case of HIV transmission in the immediate ART group, infection had been detected at day 85 of the study and further investigation suggested that the infection event was on day 1. Clearly, early ART is highly beneficial. CDC guidelines now recommend that all Adenosine HIV infected patients should have ART. Anna Lok, University of Michigan, MI, USA The number of people infected with HBV world-wide, as estimated

by the WHO and CDC in 2007, was between 223 and 240 million, but was declining due to vaccination. In the USA, vaccine use has led to a steady decline in the rate of new infections, decreasing from about 10/100,000 residents in the 1980s to about 1/100,00 today. In contrast, the prevalence of chronic hepatitis B among immigrants remains high, with no decreasing trend. When infection is acquired early in life, chronic infection is the norm. High viral load is associated with progression to liver cancer. There are 7 FDA-approved drugs to treat chronic HBV infection, including entecavir (ETV), emtricitabine (FTC) and TDF. With several years of continuous therapy, HBeAg loss is achieved in about 40% of patients but HBsAg loss (the ultimate goal, seen as a “cure”) is still a distant prospect for most patients. However, cirrhosis can be reduced by long-term antiviral treatment. In one TDF trial at 5 years, 344/348 patients had a liver biopsy which showed that 73% of patients had improved fibrosis scores (⩾2 units) and that most other patients had no worsening. TDF has now been used for 6 years without detecting HBV resistance, making it one of the first line drugs.

The full, infectious viral life cycle of human PyVs has only been

The full, infectious viral life cycle of human PyVs has only been studied for JCPyV and BKPyV because no infectious system exists up to now for the other human PyVs (Fig. 5). As PyVs are non-enveloped viruses, the viral capsid proteins interact directly with the receptor molecules in order to gain entry into the cells, being this interaction a major determinant of host and tissue tropism. Entry of PyVs into the cells includes receptor binding, internalization and intracellular trafficking, virus uncoating and nuclear entry. Once the uncoated viral genome is inside the cells, the

regulatory early proteins [Large tumor antigen (LT-ag) learn more and small T antigen (sT-ag) are produced in all PyVs. Besides LT-ag and sT-ag, other virus-specific T-antigen isoforms [such as middle T antigen Nutlin-3 ic50 (mT-ag) in rodent PyVs, the 17kT antigen in SV40 and the 57kT antigen in Merkel cell polyomavirus (MCPyV)] are derived from alternative splicing of the LT-ag transcript (Cheng et al., 2009, An et al., 2012 and Topalis et al., 2013). Some PyVs can cause tumors and products from the early region, especially SV40 LT-ag and murine PyV mT-ag, are required for cellular transformation. In benign lesions induced by PyVs, viral genomes are typically maintained extra-chromosomally. Malignant progression, as in the case of Merkel

cell carcinoma (MCC), is associated with viral integration into host cell chromatin (Fig. 3B). Although MCPyV is very common, MCC is very infrequent, most probably because integration is not part of the MCPyV life cycle and is a rare

event. This Cell press integration event is involved in the initiation of the tumor, since MCPyV was found to be clonally integrated into a single site of the host genome, indicating that viral integration preceded tumor expansion (Feng et al., 2008 and DeCaprio and Garcea, 2013). Recently, an overprinting gene, expressed from an Alternate Frame of the Large T Open reading frame (ALTO) was identified in MCPyV (Carter et al., 2013). Although ALTO is expressed during replication of MCPyV genome it is not required for replication. Despite no sequence similarities with the rodent mT-Ag, ALTO was found to be evolutionary related to mT-ag. Both PyV and PVs multiply in the nucleus of the infected cell and their circular genome associates with host encoded histones in the virions. These small DNA tumor viruses widely rely on the host cell DNA replication machinery to replicate their genomes. The LT-ag in PyVs is a multifunctional initiator protein that can successively recognize the viral origin of replication, assemble into a double hexamer melting and unwinding the DNA ahead of the replication fork, and interact with the host DNA replication factors (such as polymerase α-primase, replication protein A (RPA) and topoisomerase I (Fig. 6A).

Chang et al. (1982) observe a range from 0.00014

for undisturbed forest to 0.10 for cultivated plots as a function of decreased canopy, litter, and residual stand values. Other studies suggest C-factors as high as 0.38 for bare forests in Turkey ( Özhan et al., 2005) and 0.42 for 25% tree cover in Malaysia ( Teh, 2011). There is much uncertainty with applying Selleck GS-7340 a C-factor for a model that has no sedimentologic calibration. Average annual sheet and rill erosion across the US for forested landcover is estimated at ∼0.91 ton/acre/yr ( Gianessi et al., 1986); this provides a baseline for assessing sediment contributions to Lily Pond from the surrounding forested landscape. Using the minimum and maximum C-values found for forested cover in the literature ( Table 1) model runs suggest sediment output between 0.002 and 0.85 ton/acre/yr ( Table 3); based on this assessment, it appears the estimate using the highest C-value found during a literature search (0.42; Teh, 2011) comes closest to generating an output that resembles a US-wide mean. The erosion predictions, however, fall short of sediment-weight calculations for Lily Pond to varying degrees, www.selleckchem.com/products/byl719.html depending on C-factor used ( Fig. 11). Three contributing factors likely contribute to an underestimation of sediment yield using published C-factors: (1) the volume–weight conversion likely

overestimates sediment weight in the pond rather than underestimates it, (2) the model underestimates total sediment yield as it does not take gullying and other sediment sources into consideration, and (3) urban forests Farnesyltransferase in the region are highly erosive and should be associated by high USLE C-factor values. Certain assumptions are made in generating the sediment volume-to-dry

weight calculations (Fig. 8). Although studied cores do not appear to show much spatial variation in grain-size distribution and organic content (Fig. 6), uncertainties are presented by interpolating information from 8 cores across a surface area of ∼11,530 m2 (Fig. 6). Standard deviations for each of the conversion/correction factors are listed per core in Table 2; combining these metrics provides an idea of the overall error that may be attributed to these sedimentary analyses. While compaction measurements also vary little between core sites and therefore inferably contribute little substantial error to the analysis, a high degree of variance is displayed by the volume–weight conversion factor (Cvw), which increases uncertainty by an order of magnitude ( Table 2). A broad envelope representing the upper and lower bounds produced by this simplistic error-propagation analysis was created using the aforementioned metrics ( Table 2) and applied uniformly across the entire pond area ( Fig. 11).

A very broad scope of east-west interaction among the Northeast A

A very broad scope of east-west interaction among the Northeast Asian societies of this time is thus demonstrated (Zhushchikhovskaya, 2006). At higher latitudes in Northeastern China and the Russian Far East, the vast Amur River system provided Northeast Asia’s most productive interior fishery. In ethnohistoric times most of the Amur Basin’s considerable human population was aggregated into a small number of large settlements scattered along the Amur and its major Sungari and Ussuri tributaries. Most of the region’s known archeological sites and ethnographic period

settlements learn more are found close together and in or near communities still occupied today. Settlement patters are topographically determined, as the seasonally flooding rivers have, over ages, created the Amur region

as a vast, low-lying alluvial plain with very little relief, where a relative few localities of higher elevation have provided the only suitable places for year-around stable human occupation for millennia (Aikens and Rhee, 1992, Aikens et al., 2009 and Chard, 1974). By the early Middle Holocene, people of the related and temporally overlapping Malyshevo and Kondon cultures (∼7000–4700 cal BP) were making pottery and collecting, fishing, and hunting along the Lower Amur River while living in sedentary and substantial semi-subterranean houses. The largest of these were about 150–180 m2 in floor area and contained Methocarbamol interior storage pits as much as 2.5 m in diameter. To

the south in Primorye are known the somewhat earlier but comparable Selleckchem Proteasome inhibitor Rudnaya Pristan (8600–8265 cal BP) and Chertovy Vorota (7650–7225 cal BP) sites, both with substantial pit houses and diverse cultural inventories. The diverse remains of mammals, birds, fishes, shellfishes, nuts, and acorns preserved in Chertovy Vorota, a dry cave site, indicate the breadth of the regional resource base. As in Korea, sites of the Russian Far East also increasingly document the presence of millets (Zhushchikhovskaya, 2006). Eastward across the Sea of Japan the Jomon people practiced patterns of subsistence and settlement similar to those just described, but there have also been found a number of impressively large Early and Middle Jomon (∼6000–5000 cal BP) sites containing both small nuclear family-sized houses and much larger rectangular buildings of public importance. It is now well-demonstrated that the flourishing and diversified Early Jomon economy of Japan also included, as previously described for the Korean Chulmun case, the management or cultivation of millets, azuki bean, soybean, and beefsteak plant (Perilla frutescens), all native plants still cultivated today ( Crawford, 1997, Crawford, 2006, Crawford, 2008, Crawford, 2011b and Lee, 2011).
