The common units presented here were defined by the consortium as a whole and could represent a starting point for such discussion. However, it is clear that much remains to be done to enable a wider consensus to be reached as to how assay output data should be translated to

standardised units. Allergen analysis is often used by food manufacturers to validate and monitor allergen sanitation plans. In this instance, a manufacturer is likely to have access Selleckchem AUY 922 to the exact allergenic ingredient being analysed and, in some instances, the actual food matrix being manufactured. This allows the analytical expert to calibrate an assay against this material or even have access to an “in-house” incurred reference material using the manufactured food matrix. In such a situation, precise quantification of the allergenic food and conversion into food protein is possible (Röder et al., 2010) although it may still be necessary to convert results obtained using such “in-house” materials into reporting units that are more widely accepted and accessible to the analytical community. Precise quantification of allergens in foods will be become more

important in the future as data are becoming available that will allow levels of allergens, which pose low levels of acceptable TSA HDAC cost risk, to be identified in future, such as the ‘action’ levels already identified in VITAL. The enforcement of such regulations will require the performance issues highlighted in this inter-laboratory study to be addressed in order to ensure effective tools for verification of allergen levels in foods are available. Such methods will need to be sufficiently robust as to allow detection of allergens of unknown origin, which may be inherently variable with regards allergenic molecule composition, modifications introduced by food processing procedures (e.g., heat, pressure, pH) and interactions with other food components such as lipids and sugars. The dessert matrix used in this study would generally be consumed in a 100 g portion and the kits used were all able

to detect doses of 300 μg egg or milk protein, which equates to 2.95 mg of egg white and 8.5 μl of skimmed milk respectively. Such limits of quantification GNE-0877 are within the range of published threshold doses for egg of around 10 mg kg−1 and for milk protein of around 30 mg kg−1 (Morisset et al., 2003). However, lower doses of egg and milk protein can elicit allergic reactions with around 1% of patients having been estimated as reacting to as little as 1 mg of egg and milk (Moneret-Vautrin & Kanny, 2004), which the current methodology would struggle to detect in certain types of foods consumed in larger volumes. The multi-laboratory evaluation reported here demonstrates that the EuroPrevall dessert matrix does have promise as a naturally incurred quality control material for food allergen analysis.

The cypermethrin showed negative matrix effect for potato and water matrices, while deltamethrin, for these matrices, B-Raf cancer had a positive effect. This made the cypermethrin be located closest to the centre of the biplot graphic and deltamethrin closer to the tomato, pineapple and grape matrices. It is important to emphasise

that the behaviour of deltamethrin for the potato, water, apple, grape and tomato matrices was more significant at lower concentrations of the analyte. The iprodione and permethrin pesticides have shower negative effects for all matrices for tomatoes. The negative matrix effects presented were very significant, thus justifying the position in the biplot graphic in the same quadrant of tomato, pineapple and grape matrices when analysing the second component. According

to the results obtained in the PCA, it is clear that the matrices that caused an increase in the chromatographic response for most pesticides were tomato, pineapple and grape, which are acidic matrices. This suggests that pH is a variable that deserves to have its effects studied. Thus, to check the influence of pH on the matrix effect, all matrices studied had the pH determined. The values obtained were tomato (4.32), potato (5.74), water (6.65), apple (6.73), soil (6.76), pineapple (3.64), and grape (3.71). Water samples at pH 6.65 were adjusted to 4.32 (tomato pH), 3.64 Selleck Venetoclax (pineapple pH), and 3.71 (grape pH) and submitted to LLE-PLT.

In addition, organic extracts of tomato, pineapple and grape were obtained by SLE-PLT as described in Table 1. Standard solutions of pesticides were prepared at a concentration of 500 μg L−1 in these six extracts and in pure solvent and analysed by GC-ECD. It was observed that water acidification promoted a reduction in pesticides chromatographic response similar to the results found for samples of pure water. This behaviour was also observed for the other pesticides studied. Thus, the pH of the samples does not influence Rucaparib datasheet the properties of pesticides in the organic phase, and therefore the pH is not the directly responsible factor for the higher matrix effect observed for the more acidic samples. On the other hand, the increasing of the pH of the extracting mixture caused by the use of Na2HPO4 0.2 mol L−1 solution replacing the water used in SLE-PLT technique for samples of tomato, pineapple and grape, affected the extraction of the matrix components. Fig. 5 depicts the absorption spectra of organic extracts of the three matrices in two pH values. The spectra have the same characteristics, showing only that the organic extracts of these samples using pure water in the extracting mixture (

(25). Between Line 2 and Line 3, the substrate deforms strongly and it takes a concave shape with two inflection points, as displayed in Fig. 4(b) (phase II in Fig. 5). Between Line 3 and Line 4, the substrate possesses a convex morphology, corresponding to Fig. 4(d) (phase III in Fig. 5). Similar shapes can be verified by the finite element method in analysis of a droplet wrapped by a soft plate. [31]. Up Line 4, the valid shape of the vesicle-substrate system does not exist. Moreover, our findings can also set some illustrations of the opening angle of a soft membrane adhered by a droplet, which was controlled by the voltage [30]. It is found that when the voltage IDO inhibitor is zero, the opening angle has two

possible solutions, i.e. one is negative and the other is positive. In our model, we introduce the definition of opening angle of the substrate φ = 2ϕ0 − π, and the relationship between the opening angle and the reduced work of adhesion Erastin research buy with a fixed value of κ1/κ2 = 0.5 can be plotted in Fig. 6. From the figure we can see that there are two or three solution branches. In addition, the opening angle decreases with the increase of the work

of adhesion in a large range, which can be analogous to the droplet-membrane controlled by the electric voltage [30]. When w > 1.025, phase II (low branch) has lower energy and when 0.78 < w < 1.025, phase IV (green branch) has lower energy. When w < 0.78, there is only one solution. In the similar phenomenon, the voltage was input when the membrane-droplet is like phase I in Fig. 3, and the opening angle decreases with the increase of the voltage Vitamin B12 [30]. If the voltage is input to the droplet-membrane system like phase II in Fig. 3, shape saturation will occur and there is a sudden jump of the opening angle from point p to point p′. The developed model can certainly degenerate to the case of a vesicle adhering on a rigid substrate, where κ1/κ2 = 0. In this case, the function of the reduced free energy versus the reduced work of adhesion can be calculated, and the curve is demonstrated in Fig. 7. Clearly, the free energy of the system decreases

with the increase of the work of adhesion. This means that if a cell is deposited on a rigid substrate, it is prone to the position with strong adhesion capability. This result can provide some inspirations to control the moving direction of a living cell on a rigid substrate, by engineering some special materials with different surface energies. Fig. 8 shows the projected length as a function of the work of adhesion. The curve tells us that the projected length (as schematized in the figure) decreases with the increase of the work of adhesion, and this result is in agreement with the former experimental phenomenon [9]. In conclusion, a systematic analysis of a vesicle adhered to an elastic substrate was performed.

, 2010). Here we compare the efficacy of multi-cohort based management, aimed specifically at maintaining stand structure, and shelterwood silvicultural systems, which may provide some de facto benefit for biodiversity, for maintaining ground beetle assemblages. We also compare both of these partial cutting approaches with standard clear cuts to assess any net benefits partial cutting may provide if implemented within a larger strategy of ecosystem management. We hypothesize that the higher ALK inhibitor levels of retention left following

multi-cohort management will be more similar to uncut forests than either shelterwood or clear cuts. All sample sites were located in the Haute-Mauricie region of Québec, Canada (47°26′16″N, 72°46′35″W) and were dominated primarily by balsam fir (Abies balsamea (L.) Miller) and yellow birch (Betula alleghaniensis Britton), although numerous other hardwood (including sugar maple (Acer saccharum Marshall), red maple (Acer rubrum L.), trembling aspen (Populus tremuloides Michx.) and conifer (white spruce (Picea glauca (Moench) Voss), red

spruce (Picea rubens Sarg.), jack pine (Pinus banksiana Lamb.), and white pine (Pinus strobus L.)) species were also present. Stand dynamics are controlled predominately by frequent, small fires (<150 ha) and infrequent, large fires (>10,000 ha), windthrow ( Côté et al., 2010), as well as outbreaks of spruce budworm (Choristoneura fumiferana (Clemens)). We sampled beetles from replicate stands Selleck Lapatinib that were clear cut, harvested according to either shelterwood or multicohort silvicultural systems or uncut (Fig. 1). These sites were part of a larger project called TRIADE, which was established to evaluate how partial cutting and other ecosystem management options could be incorporated and implemented over a larger landscape (Côté et al., 2010). Our study stands originated from a wildfire in 1923. Stands were

harvested during the winter of 2007–2008 (Witté et al.). Dapagliflozin Clear cuts, in our study, contained 5% retention isolated within a small aggregate (between 150 and 500 m2). Retention within the shelterwood treatments consisted of a 5 m band of uncut forest with two adjacent 7 m bands of partial cut forest where retention was 50% of pre-harvest stem density. Each vegetation strip (19 m total width) was separated by 5 m of harvested forest where retention was 0%. In 10–15 years once significant conifer regeneration has established, the 5 m uncut band will be harvested along with larger stems from the adjacent 7 m partial cut strips. Retention within the multicohort treatment consisted of an uncut vegetation strip 19 m wide bordered on each side by a 7 m wide partial cut strip which retains 66% of the original stems. This larger vegetation strip (33 m) is separated from other strips by a 5 m band of harvested forest where retention was 0%.

Ginseng may also be beneficial for those infected with the human immunodeficiency virus; long-term ginseng use has been linked to slowed depletion of CD4 T lymphocytes in such patients [34]. The present study demonstrates that mice and ferrets fed with Red Ginseng could be protected from the lethal challenges of HP H5N1 influenza virus. The results hold out the potential that Red Ginseng may contribute to protecting humans from pandemic influenza virus prior to when the pandemic vaccine or an effective anti-influenza

drug is available. In the event of such a pandemic, an estimated 30% of the global human population would Selleckchem Trametinib be at risk of infection, because most humans do not have prior immunity to pandemic influenza virus. Considering the vast geographic distribution of HP H5N1 influenza virus and its ability to Selleckchem Doxorubicin infect humans, H5N1 influenza virus is a prime candidate as a pandemic cause [35] and [36]. During such an event, daily consumption of Red Ginseng may increase the likelihood of human survival from exposure to a lethal dose of HP H5N1 influenza virus, at least until an effective vaccine becomes available and prophylactic protection can be established. The pandemic vaccine can be developed only after the pandemic virus is available because HP H5N1 influenza virus continuously evolves [37]. In addition, HP H5N1 influenza virus that is resistant to the most used anti-influenza drug, Oseltamivir,

PI-1840 has already emerged [38]. Our results indicate that the underlying mechanism that

feeding of mice and ferrets with Red Ginseng help to increase the survival rate of these animals from the lethal infections of HP H5N1 influenza virus may be due to the enhanced inductions of antiviral cytokines of IFN-α and IFN-γ. It is well established that IFN-α and IFN-γ could inhibit the replication of influenza viruses [39] and [40]. Further studies such as cytokine production, viral titers, and histological pathology in ferrets may be needed to support the immune enhancing effects of Red Ginseng against HP H5N1 influenza virus. At this moment, no commercially available ELISA kits for measuring ferrets’ cytokines at the level of proteins exist. In summary, we studied the effects of Red Ginseng on protective immunity of mice and ferrets against HP H5N1 influenza virus. Our results suggest that taking Red Ginseng daily may contribute to protecting humans from the lethal infections of HP H5N1 influenza virus in the event of a pandemic by HP H5N1 influenza virus.

“Ginseng, the root of Panax ginseng Meyer, is one of the most popular traditional herbal medicines. It has been used for thousands of years in Asian countries, and has also recently become popular in Western countries.

A total of 61 patients were screened for eligibility. The

characteristics of the included sample are reported in Table 1. The most common reasons for noneligibility were age and acute psychosis. All participants (N = 13) were prescribed concurrent psychiatric medications and n = 1 was treated with ECT parallel to BA. Of the 13 participants that started treatment n = 10 completed the minimum of 8 sessions. Anti-cancer Compound Library A total of n = 9 completed 11 or 12 sessions. Three patients dropped out prematurely at Session 1 (n = 1) or 2 (n = 2). One participant stated that she dropped out due to significant memory loss following the ECT. The mean duration of BA-treatment for completers was 9.3 weeks (SD = 3.1). The mean number of sessions received during hospital admission was 3.5 (SD = 2.4). The mean duration of inpatient admission was 20.4 days (SD = 14.4). One participant was rehospitalized during the treatment period but was discharged prior to the last session. Results from the TCS after Session 3 (M = 40.5, SD = 6.2) indicated high credibility and expectancy for change. The CSQ-8 after treatment (M = 28.2, SD = 3.3)

indicated high satisfaction. Results from the WAI at Session 3 (M = 66.2, SD = 11.2), Session 6 (M = 70.6, SD = 7.3), and Session 9 (M = 75.40, SD = 7.1) ALK assay indicated a good working alliance. A one-way repeated measures ANOVA indicated that it improved over the TCL course of treatment, F(2, 18) = 4.912, p = .02. Following treatment participants were also asked open-ended questions about their experience of therapy. Below we report the answers that did not overlap each other: 1. What did you think about initiating

therapy while admitted on the inpatient unit? The BADS-SF total score improved gradually over the course of treatment from baseline (M = 16.20, SD = 6.4), Session 3 (M = 20.8, SD = 6.2), Session 6 (M = 25.4, SD = 6.1), Session 9 (M = 29.1, SD = 5.6) to posttreatment (M = 33.10, SD = 10.6). A one-way repeated measures ANOVA for BADS-SF indicated a significant time effect, F(4, 48) = 10.367, p < .001. Descriptive statistics for participants’ homework compliance are reported in Table 2. Significant improvements and large effect sizes were indicated for MADRS-S, F(4, 36) = 18.79, p < .001, d = 2.60), clinician rated MADRS, t(9) = 6.292, p < .001, d = 2.43, self reported GAF, t(9) = -4.525, p < .001, d = 2.11, and the clinician-rated GAF, t(9) = -5.628, p < .001, d = 2.21. No significant improvements were observed in the SDS, t(9) = 2.101, p = .065, d = .63. The above pattern of significance and effect size magnitude was repeated when looking at the intention-to-treat sample using last observation carried forward. Changes in BADS-SF from baseline to posttreatment were significantly correlated with depressive symptom improvements over the course of treatment on the MADRS-S (r = -.681, p = .01).

, 2003, Hsu et al., 2003 and Poutanen et al., 2003). Another broad spectrum antiviral agent, ribavirin, a purine nucleoside analogue that inhibits guanosine triphosphate synthesis and viral RNA polymerase activity, was commonly given to patients in Asia and North America. Of 2546 patients with descriptions of medical treatment for SARS reported in the literature, 1316 (51.7%) of them received ribavirin, either as the primary treatment regimen or in combination with a corticosteroid Ipilimumab or other antiviral agent such as lopinavir/ritonavir

(Table 2). The regimens of ribavirin included: • intravenous formulation of 8 mg/kg every 8 h for 14 days; However, the role of ribavirin remained uncertain, as there was no obvious clinical benefit in a retrospective, uncontrolled cohort analysis involving 229 patients in Singapore

(Leong et al., 2004). Although in vitro studies also demonstrated that ribavirin had no significant activity against SARS-CoV in Vero cells ( Cinatl et al., 2003), ribavirin had good activity when it was tested in human Caco-2 and pig kidney cell lines ( Morgenstern et al., 2005). Moreover, ribavirin was shown to be synergistic with interferon in in vitro combination assays ( Chen et al., 2004). The low level of in vitro activity DAPT against SARS-CoV might be attributed to cellular toxicity, as the 50% cytotoxic dose of ribavirin on various cell lines has been reported to be approximately 200–1000 μg/mL ( Tan et al., 2004). Adverse effects of ribavirin were not uncommon. In a cohort of 110 patients in Toronto, dose-related hemolytic anemia was observed in 61% of patients, whereas hypocalcaemia and hypomagnesaemia was reported in 58% and 46% respectively ( Knowles et al., 2003). In another

cohort of 44 patients in Taiwan, 73% of patients had a drop in hemoglobin Resveratrol level 3 days after therapy with ribavirin which was found to be an independent prognostic factor of hypoxemia or mortality ( Chiou et al., 2005). Some patients were treated with a boosted HIV protease inhibitor, with a combination of lopinavir and ritonavir as either initial therapy or rescue therapy along with ribavirin in the evolving epidemic (Chan et al., 2003 and Chu et al., 2004a). In vitro antiviral susceptibility testing showed that the cytopathic effect of SARS-CoV was inhibited by lopinavir at 4 μg/ml and ribavirin at 50 μg/ml after 48 h of incubation. Inhibition of the cytopathic effect was achieved down to a lopinavir concentration 1 μg/ml combined with ribavirin 6.25 μg/ml, only when the viral inoculum was reduced to 50 TCID50 or below, suggesting potential synergistic activity ( Chu et al., 2004a). The addition of lopinavir/ritonavir as initial treatment was associated with a reduction in the overall death rate (2.3%) and intubation rate (0%), when compared with a matched cohort who received standard treatment with ribavirin (15.6% and 11.0% respectively, P < 0.05).

AMPAkines are modulators of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors and have been widely explored for a variety of neuropsychiatric diseases including schizophrenia and epilepsy (Chang et al., 2012 and Russo et al., 2012). Cognitive improvement has been the primary focus of most

research with this drug class (Hamlyn et al., 2009). Glutamate acting via AMPA receptors is essential for maintaining respiratory rhythmogenesis at the purported kernel of rhythm generation, the preBötzinger complex in the hindbrain (Funk et al., 1993 and Greer et al., 1991). Thus, the rationale for the use of AMPAkines to treat respiratory depression, in particular the type caused primarily by a decrease in respiratory selleck inhibitor rate (e.g., opioid-induced respiratory depression), is that positive allosteric modulators of AMPA receptors would enhance respiratory rhythm. Various AMPAkines

(Cortex Pharmaceuticals, Inc.) have been evaluated preclinically and clinically as respiratory DAPT stimulants. The positive AMPA allosteric modulator CX546 reversed the ventilatory suppressive effects of fentanyl and phenobarbital in the rat (Ren et al., 2006). A second AMPA receptor modulator, CX717, has been tested pre-clinically and is also able to reverse the respiratory depressive effects of fentanyl, alcohol and pentobarbital (Ren et al., 2009 and Ren et al., 2012). CX717 also reverses opiate suppression of hypoglossal motor neurons (Lorier et al., 2010). In young healthy subjects with a target alfentanil infusion concentration of 100 ng/mL (i.e., analgesic), CX717 prevented the fall in respiratory rate vs. placebo (Oertel et al., 2010). However, in that study there also was an interaction

between alfentanil and CX717 with respect to visual analog scale parameter “tiredness”, in that the participants receiving CX717 reported increased tiredness compared to placebo controls. In humans, AMPAkines improved memory and information processing in the healthy elderly (Wezenberg et al., 2007) and people with schizophrenia (Goff et al., 2008). In a randomized, double-blind, crossover study in sleep deprived young subjects, CX717 enhanced cognitive performance and alertness (Boyle et al., 2012). Slow wave sleep was reduced and recovery sleep impaired. Thus, the respiratory stimulatory effects of new AMPAkine molecules are associated with Fenbendazole stimulatory neuropsychiatric effects on arousal-alertness state and cognitive performance. It remains possible that dual effects of a single molecule on the neuropsychiatric and respiratory systems will limit the utility of these compounds as respiratory stimulants. Agents that increase the drive to breathe by mimicking the effects of acute hypoxia and/or hypercapnia at the level of the peripheral chemoreceptors represent a rational approach toward the development of therapeutics for breathing control disorders that would benefit from ventilatory stimulation.

KRG and its extracts have been shown to possess multiple pharmacological activities that are useful for treating various human diseases, such as cardiovascular diseases, hypertension, wounds, cerebral ischemia, diabetes mellitus, liver regeneration, antiangiogenesis, and rheumatoid learn more arthritis [12], [13], [14], [15], [16], [17] and [18]. In recent days, the use of whole ginseng products such as steamed ginseng (KRG), ginseng powder, and ginseng extracts has seen a resurgence in use as alternative medicines in Europe as

well as in Asian countries. However, the protective activity of KRG against Dex-induced osteoporosis in vitro and in vivo has not yet been comprehensively explained. In this study, we determined the protective effects of KRG against Dex-induced apoptosis, as well as the molecular mechanism

regulated by KRG in MC3T3-E1 cells in vitro and the alteration of trabecular bone loss in a GC-induced osteoporosis mouse model in vivo. All the cell culture media and supplements were Gibco products (Life Technologies, Waltham, MA, USA). RNAisol and all polymerase chain reaction (PCR) reagents were obtained from Takara Bio Inc. (Shiga, Japan). Dex, ascorbic acid, β-glycerophosphate, and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) were obtained selleck kinase inhibitor from Sigma-Aldrich (St Louis, MO, USA). Antiphospho-p38 mitogen-activated protein kinase (Thr180/Tyr182), antiphospho-c-Jun N-terminal kinase (p-JNK; Thr183/Tyr185), antiphospho-AKT (p-AKT; ser 473), and anti-β actin antibodies were

purchased from Cell Signaling Technology (Danvers, MA, USA). KRG extracts were provided by the Korea Ginseng Corporation (Daejeon, Korea) from the roots of a 6-year-old red ginseng (Panax ginseng Phospholipase D1 Meyer) plant harvested in the Republic of Korea. KRG was prepared by steaming fresh ginseng at 90–100°C for 3 h and then drying at 50–80°C. KRG extract was prepared from red ginseng water extract, which was extracted at 85–90°C using three 8-h cycles of circulating hot water. Water content of the pooled extract was 36% of the total weight. KRG was analyzed by high-performance liquid chromatography. The major ginsenosides present in KRG extract were as follows: Rb1, 7.53 mg/g; Rb2, 2.86 mg/g; Rc, 2.86 mg/g; Rd, 0.89 mg/g; Re, 1.90 mg/g; Rf, 1.12 mg/g; Rg1, 1.78 mg/g; Rg2s, 1.12 mg/g; Rg3r, 0.72 mg/g; and Rg3s, 1.37 mg/g; minor ginsenosides were also present. Osteoblastic MC3T3-E1 cells (CRL-2593; ATCC, VA, USA) were cultured in a growth medium consisting of minimal essential medium (α-MEM) with 10% fetal bovine serum (FBS) and 1% penicillin/streptomycin. Cells were incubated in a humid incubator at 37°C (95% O2 and 5% CO2) and maintained in a subconfluent state unless otherwise indicated. Cells were subcultured every 72 h using 0.2% trypsin and 0.02% ethylenediamine tetra-acetic acid. For experiments, cells were cultured for 24 h to obtain monolayers containing α-MEM with 10% FBS.

In this paper, I explore a widespread stratigraphic marker of human presence and ecological change that has been largely neglected in discussions of the Anthropocene: anthropogenic shell midden soils found along coastlines, rivers, and lake shores around the world. Shell middens have a deep history that goes back at least 165,000 years, but the spread of Homo sapiens around the world during the Late Pleistocene and Holocene, along with a stabilization of global sea levels in the Early Holocene, led to a worldwide proliferation of shell middens. Anthropologists have long considered this global appearance

of check details shell middens to be part of a ‘broad spectrum revolution’ that led to the development of widespread agricultural societies ( Bailey, 1978, Binford, 1968 and Cohen, 1977). In Rigosertib ic50 the sections that follow, I: (1) discuss the effects of sea level fluctuations on the visibility of coastal shell middens; (2) briefly review the evidence for hominid fishing, seafaring,

and coastal colonization, especially after the appearance of anatomically modern humans (AMH); (3) summarize the evidence for human impacts on coastal ecosystems, including a case study from California’s San Miguel Island; and (4) discuss how shell middens and other anthropogenic soils worldwide might be used to define an Anthropocene epoch. We live in an interglacial period (the Holocene) that has seen average global sea levels rise as much as 100–120 m since the end of the Last Glacial Maximum about 20,000 years ago (Fig. 1). Geoscientists have long warned that rising postglacial seas have submerged ancient coastlines and vast areas of the world’s continental shelves, potentially obscuring archeological evidence for early coastal occupations (Emery and Edwards, 1966, Shepard, 1964 and van Andel, 1989). Bailey et al. (2007) estimated that sea levels were at

least 50 m below present during 90% of the Pleistocene. During the height of the Last Interglacial (∼125,000 years ago), however, global sea levels were roughly 4–8 m above present, causing coastal erosion that probably destroyed most earlier evidence for coastal occupation by humans and our ancestors. The effects of such Fludarabine wide swings in global sea levels leave just the tip of a proverbial iceberg with which to understand the deeper history of hominin coastal occupations. As a result, many 20th century anthropologists hypothesized that hominins did not engage in intensive fishing, aquatic foraging, or seafaring until the last 10,000 years or so (Cohen, 1977, Greenhill, 1976, Isaac, 1971, Osborn, 1977, Washburn and Lancaster, 1968 and Yesner, 1987)—the last one percent (or less) of human history (Erlandson, 2001). In this scenario, intensive fishing and maritime adaptations were linked to a ‘broad spectrum revolution’ and the origins of agriculture and animal domestication (see McBrearty and Brooks, 2000).
