Modeling Modes of Hunter-Gatherer Food Storage
Authors: Morgan Christopher 
Published: October 2012

AbstractAnalyses of the capacity and rates of different acorn storage techniques employed by the Western Mono of California’s Sierra Nevada during the very late Holacene indicate hunter-gatherers store food in at least three main modes: central-place storage, dispersed caching, and dispersed bulk caching. The advantage of caching modes over central-place ones is that they entail faster storage rates and thus the chance to maximize storage capacity when seasonality and scheduling conflicts limit storing opportunities. They also result in predictable stores of acorn separate from winter population aggregations but oftentimes near seasonally occupied camps. Central-place storage thus appears most directly related to coping with single-year seasonal variability in environmental productivity and sedentary overwintering strategies; caching, and especially bulk caching, with multi-year environmental unpredictability, overwintering and seasonal residential moves. Storage thus appears to generally develop as a response to seasonality and unpredictable environmental productivity, but its various forms are conditioned mainly by how they articulate with different mobility types. Complex Mono storage behaviors, however, were associated with regionally low population densities and relatively uncomplicated social structures nonetheless characterized by chiefs who maintained their positions by throwing feasts of stored acorn. The connections between storage, population density, and sociocultural complexity thus appear less direct and predicated on specific sociopolitical circumstance. Recognizing different modes of hunter-gatherer storage is consequently critical to assessing the roles ecology, mobility, group size, and social distinctions play in the development of disparate storage behaviors.
Archaic Period Shell Middens, Sea-Level Fluctuation, and Seasonality: Archaeology along the Northern Gulf of California Littoral, Sonora, Mexico

AbstractFive recent radiocarbon assays on wood charcoal within archaeological sites from the Puerto Peñasco area, Sonora, Mexico indicate use of the marine resources of the northern Gulf of California area during the Middle Archaic through the Late Archaic periods, ca. 3800 B.C.–A.D. 100. The archaeological shell middens of the region are generally thought of as remains associated with Ceramic period Hohokam marine shell collecting forays with there being little consideration given to the likelihood of an Archaic period component being present. The importance of these age estimates is that they are derived from carbonized botanical remains rather than shell. Because of considerable variability in the carbon reservoir effect, age estimates derived from marine shell from the northern Gulf of California have limited reliability. The seasonality of collection is also considered through a preliminary study of stable oxygen isotope ratios in two shell samples. The results suggests that these shellfish were collected in the late fall, winter, and perhaps very early spring.

Published: October 2012

AbstractMcCall (2010) uses data collected by Pager (1971) to argue for geographically controlled differences in the uses of painted rock art sites in the Didima Gorge, South Africa. We point out fundamental errors in the ascription of sites to particular categories that undermine the conclusions he reached. We conclude that there is no evidence to suggest different uses of painted rock shelters in the Didima Gorge.
Pour un « machiavélisme postkantien »
Authors: Châton Gwendal 
Published: October 2012

Raymond Aron est souvent décrit comme l’un des grands théoriciens du réalisme moderne. Cette manière de l’insérer dans les taxinomies traditionnelles doit cependant être interrogée. Une lecture attentive de son oeuvre permet en effet de constater qu’Aron a élaboré une approche singulière sur la base d’une double critique : celle d’une tradition libérale qui a généré des projets jugés illusoires ; celle d’un réalisme de guerre froide qui s’est mué en idéologie simplificatrice. L’originalité de l’approche aronienne réside donc dans la tentative de surmonter l’opposition classique de ces deux « écoles », en conservant la meilleure part de chacune d’elles. C’est pourquoi on propose d’envisager Raymond Aron comme un théoricien réaliste hétérodoxe, comme le tenant d’un « machiavélisme postkantien ».
Abdominopelvic Actinomycosis Associated With an Intrauterine Device and Presenting With a Rectal Mass and Hydronephrosis: A Troublesome Condition for the Clinician

Published: October 2012

AbstractActinomycosis is an uncommon, chronic, granulomatous disease that can be mistaken for a malignant tumor. Abdominopelvic actinomycosis constitutes about 20% of all actinomycosis cases and may mimic malignancy, tuberculosis, or other abdominopelvic inflammatory diseases. This condition is more prevalent in women who use an intrauterine device. We treated a 44-year-old woman who presented with vaginal discharge, right flank pain, dysuria, and difficulty with defecation. She had anorexia and weight loss (8 kg) during the previous 2 months and had a history of intrauterine device use for 12 years. Clinical, radiologic, and endoscopic examinations revealed a rectal mass and right hydronephrosis. Rectal biopsy showed nonspecific colitis. Laparotomy showed a mass that was invading and obstructing the pelvic orifice. Surgery included total abdominal hysterectomy, bilateral salpingo-oophorectomy, appendectomy, low anterior resection, and Hartmann colostomy. Histopathologic evaluation of surgical specimens showed actinomycosis originating from the tubo-ovarian structures and invading the rectal wall. The patient was placed on penicillin for 6 months, and then had closure of the colostomy with no complication.

AbstractWe report a case of neuronal hypertrophy associated with acute appendicitis in which significant neuronal fibers and the number of ganglion cells increased in the absence of inflammatory cells. Differential diagnosis from diffuse ganglioneuromatosis by the pathologic findings of resected specimen was difficult. A 33-year-old Japanese female visited our hospital complaining of acute abdominal pain. The patient underwent appendectomy upon the diagnosis of acute appendicitis on the day of admission. Postoperative examinations found no neoplastic lesions in other organs or inherited disorders such as multiple endocrine neoplasia (MEN) type 2b and von Recklinghausen's disease (VRD). The pathologic diagnosis was neuronal hypertrophy of the appendix. Because the clinical outcomes of diffuse ganglioneuromatosis and neuronal hypertrophy of the gastrointestinal tract are quite different, clinical and pathologic examination should be carefully carried out for lesions in which significant proliferation of neuronal components is seen.

Abstract
A 58-year-old female with hepatitis C was referred to our hospital after computed tomography (CT) revealed a tumor in the right lobe of her liver. After thorough examination, tumor thrombosis was detected on the main trunk of the portal vein, and we decided to administer a combination of subcutaneous interferon-alfa and intra-arterial 5-fluorouracil. However, after 2 cycles of treatment, this regimen was ineffective, and thus cisplatin (CDDP) was added for the third cycle. On completion of 5 treatment cycles, the tumor and portal vein tumor thrombosis were not detected by CT or 18F-2-fluoro-2-deoxy-D-glucose positron emission tomography. Hence, chemotherapy was considered effective and stopped. Two years after chemotherapy, Alpha-fetoprotein (AFP) and protein induced by vitamin K absence or antagonists-II (PIVKA-II) levels were within normal limits. Combination therapies have been recognized recently, and judging from the above case, the addition of CDDP to the combination regimen can prove beneficial.

Abstract
The aim of this study is to analyze the risk factors for complications and recurrence in pilonidal sinus disease. The prospective study consisted of 144 patients with pilonidal sinus disease who were operated on at Dicle University Medical Faculty, Department of General Surgery, between February 2008 and December 2010. Patients receiving the Limberg flap totaled 106 (73.6%), while 38 (26.4%) had primary closure. Postoperative complications developed in 42 subjects (29.2%), and recurrence occurred in 19 (13.2%). The Limberg flap method was statistically considered as a risk factor for postoperative complications (P  =  0.039). Regarding recurrence, family tendency (P  =  0.011), sinus number (P  =  0.005), cavity diameter (P  =  0.002), and primary closure (P  =  0.001) were found to be risk factors. Postoperative complication rate is higher in the Limberg flap method than primary closure method. The risk of recurrence is related to family tendency, sinus number, cavity diameter and anesthesia type and is also higher in primary closure.
Colorectal Cancer Treatment and Follow-Up in the Elderly: An Inexplicably Different Approach

Abstract
The incidence of colorectal cancer increases as age progresses. At present, elderly patients have received substandard cancer treatment not supported by “evidence.” Geriatric assessment should be performed preoperatively and selected elderly patients must be offered standard surgical treatment receiving the same complementary therapies as a younger patient. It should be stressed that elderly patients should not be deprived of their decision-making role. In our experience, more than 43% of patients with colorectal cancer are ≥70 years of age, and we believe that they should receive the same type of follow-up. This would allow for the detection and removal of polyps, treatment of malignant tumors, and psychological support similarly to younger patients. Significantly, in our experience, the incidence of reoperation for neoplastic disease is similar in the two patient populations.
The Angry Juror: Sentencing Decisions in First‐Degree Murder
Authors: Georges Leah C. , Wiener Richard L. , Keller Stacie R. 
Published: October 2012

SummaryA great deal of research in legal decision making has overlooked the influence of affect on the decision‐making process. The present study measured the fluctuation of emotions across five time points of a capital trial and tested the overall relationship between changes in emotion and sentencing decisions. The results showed that across all participants, anger initially increased and then decreased during the course of a capital punishment trial. Most importantly, the more individual mock jurors' anger increased during any stage of the trial, the more likely they were to assign a death sentence. Furthermore, when jurors' anger increased, they rated mitigating factors presented by the defense as weaker and the weaker mitigation mediated the relationship between change in anger and sentencing. The paper ends with a discussion of theoretical explanations and policy implications. Copyright © 2012 John Wiley & Sons, Ltd.
Synthesis of Carboxy‐Functionalized Polycyclic Arenes by Oxidative Cyclizations of 2,3‐Diarylacrylates

Published: October 2012

AbstractThe cyclization of esters of Perkin condensation products by oxidation with 2,3‐dichloro‐5,6‐dicyanobenzoquinone (DDQ) in the presence of MeSO3H is examined as a three‐step approach from arylacetic acids and aromatic aldehydes to functionalized condensed arenes. The method is limited to systems in which one or both of the two aryl moieties are more reactive than a phenyl group, such as 1‐naphthyl or, especially, 3‐thienyl. Alkoxycarbonyl derivatives of picene, benzo[c]chrysene, three isomeric phenanthrothiophenes, a naphthothiophene, and a benzodithiophene were obtained. The extension of this approach to multiple cyclizations and, thus, to extended partially condensed systems with multiple alkoxycarbonyl substituents appears promising with highly active precursors derived from 3‐thienylacetic acid. In this case, conjugated polymers made of short ribbon fragments linked by thiophene–thiophene single bonds appear conceivable. A bifunctional chrysenodithiophene was obtained from 1,5‐diformylnaphthalene, together with a highly unusual asymmetric dimer that contains a cyclohepta[de]naphthalene (pleiadiene) moiety.
Brief communication: New Y‐chromosome binary markers improve phylogenetic resolution within haplogroup R1a1

Published: October 2012

AbstractHaplogroup R1a1‐M198 is a major clade of Y chromosomal haplogroups which is distributed all across Eurasia. To this date, many efforts have been made to identify large SNP‐based subgroups and migration patterns of this haplogroup. The origin and spread of R1a1 chromosomes in Eurasia has, however, remained unknown due to the lack of downstream SNPs within the R1a1 haplogroup. Since the discovery of R1a1‐M458, this is the first scientific attempt to divide haplogroup R1a1‐M198 into multiple SNP‐based sub‐haplogroups. We have genotyped 217 R1a1‐M198 samples from seven different population groups at M458, as well as the Z280 and Z93 SNPs recently identified from the “1000 Genomes Project”.The two additional binary markers present an effective tool because now more than 98% of the samples analyzed assign to one of the three sub‐haplogroups. R1a1‐M458 and R1a1‐Z280 were typical for the Hungarian population groups, whereas R1a1‐Z93 was typical for Malaysian Indians and the Hungarian Roma. Inner and Central Asia is an overlap zone for the R1a1‐Z280 and R1a1‐Z93 lineages. This pattern implies that an early differentiation zone of R1a1‐M198 conceivably occurred somewhere within the Eurasian Steppes or the Middle East and Caucasus region as they lie between South Asia and Eastern Europe. The detection of the Z93 paternal genetic imprint in the Hungarian Roma gene pool is consistent with South Asian ancestry and amends the view that H1a‐M82 is their only discernible paternal lineage of Indian heritage. © 2012 Wiley Periodicals, Inc.
Theta event‐related synchronization is a biomarker for a morbid effect of alcoholism on the brain that may partially resolve with extended abstinence
Authors: Gilmore Casey S. , Fein George 
Published: October 2012

AbstractAnalyzing the induced (non‐stimulus‐phase‐locked) EEG activity elicited by targets in a three‐condition visual oddball task, Fein and colleagues have shown increased theta band event‐related synchronization (ERS) in two different samples of long‐term abstinent alcoholics (LTAA) compared with age‐ and gender‐comparable controls. The theta ERS effect in alcoholics was also shown to be independent of, and opposite in direction to, the reduced amplitude evoked (stimulus‐phase‐locked) activity typically found in alcoholics and those at genetic risk of developing alcoholism. This study extends these findings by applying time‐frequency analysis to target stimulus event‐related EEG to compare evoked and induced theta activity in 43 LTAA and 72 nonalcoholic controls with a group of 31 alcoholics who just recently initiated abstinence from alcohol (between 6‐ and 15‐week abstinent; referred to as short‐term abstinent alcoholics, STAA). Results demonstrated that (1) evoked theta power was reduced to the same degree in STAA and LTAA compared with nonalcoholic control participants, while (2) induced theta activity, measured by theta ERS, was increased in both STAA and LTAA relative to controls, but was also increased in STAA relative to LTAA. The STAA and LTAA groups did not differ on measures of alcohol use severity or family history of alcohol problems. These results, coupled with previous findings that show a relationship between stronger theta ERS and increased memory load and attention allocation, suggest that increased theta ERS may be a biomarker for a detrimental effect of chronic alcohol abuse on the brain – a detriment that may recover, at least partially, with extended abstinence.
Factors associated with supracricoid laryngectomy functional outcomes

Published: October 2012

BackgroundSupracricoid partial laryngectomy (SCPL) is an option for laryngeal cancer resection that preserves laryngeal function; however, little information exists regarding factors that are associated with functional outcomes.MethodsA medical chart review was performed on patients that underwent SCPL at our institution between 2006 and 2011. Data were collected on surgical, voice, and swallowing outcomes.ResultsEighteen patients were identified. Thirteen underwent cricohyoidoepiglottopexy (CHEP) and 5 had a cricohyoidopexy (CHP). Mean follow‐up was 737 days. On average, decannulation occurred at 27.4 days and feeding tube removal at 87.9 days postoperatively. Sixty‐seven percent of patients tolerated an unrestricted diet at follow‐up. Increased age and a CHP procedure were associated with negative outcomes. Age may be a proxy for more extensive disease and prior treatments.ConclusionPatients who undergo an SCPL require extensive rehabilitation after surgery. Those who have undergone multiple cancer interventions and have more extensive surgery may be at risk for poorer outcomes. © 2012 Wiley Periodicals, Inc. Head Neck 35: 1397–1403, 2013
Phase composition control of calcium phosphate nanoparticles for tunable drug delivery kinetics and treatment of osteomyelitis. I. Preparation and drug release
Authors: Uskoković Vuk , Desai Tejal A. 
Published: October 2012

AbstractDeveloped in this study is a multifunctional material for simultaneous osseoinduction and drug delivery, potentially applicable in the treatment of osteomyelitis. It is composed of agglomerates of nanoparticles of calcium phosphate (CAP) with different monophasic contents. The drug‐loading capacity and the release kinetics were investigated on two model drug compounds with different chemical structures, sizes, and adsorption propensities: bovine serum albumin and fluorescein. Loading of CAP powders with small molecule drugs was achieved by physisorption and desiccation‐induced agglomeration of nanoparticulate subunits into microscopic blocks. The material dissolution rate and the drug release rate depended on the nature of the CAP phase, decreasing from monocalcium phosphate to monetite to amorphous CAP and calcium pyrophosphate to hydroxyapatite. The sustained release of the two model drugs was shown to be directly relatable to the degradation rate of CAP carriers. It was demonstrated that the degradation rate of the carrier and the drug release kinetics could be made tunable within the time scale of 1–2 h for the most soluble CAP phase, monocalcium phosphate, to 1–2 years for the least soluble one, hydroxyapatite. From the standpoint of antibiotic therapy for osteomyelitis, typically lasting for 6 weeks, the most prospective CAP powder was amorphous CAP with its release time scale for a small organic molecule, the same category to which antibiotics belong, of 1–2 months under the conditions applied in our experiments. By combining these different CAP phases in various proportions, drug release profiles could be tailored to the therapeutic occasion. © 2012 Wiley Periodicals, Inc. J Biomed Mater Res Part A, 2013.
In situ forming, resorbable graft copolymer hydrogels providing controlled drug release

Published: October 2012

AbstractIn situ forming hydrogels are promising drug delivery vehicles due to their ease of delivery as liquids and their ability to be used in sites with irregular geometries. In this work, we report on in situ forming, resorbable hydrogels based on N‐isopropylacrylamide (NIPAAm) as a fluid‐like controlled release gel. These gels are the first resorbable NIPAAm‐based gels providing controlled release without relying on affinity between the drug and device. Therefore, these gels provide a more flexible delivery system which can be used to deliver any drug at a controlled rate. The polymers contain repeat units of NIPAAm with (R)‐α‐Acryloyloxy‐β,β‐dimethyl‐γ‐butyrolactone (DBLA) and varying amounts of hydrophilic Jeffamine® M‐1000 acrylamide (JAAm) grafts. The graft copolymer architecture allows the water content of the hydrogels to be tuned over a wide range while keeping the initial gelation temperature below body temperature. Incorporation of JAAm in the polymers led to greater water content, faster gel degradation, and reduced burst release. Sustained release of the antimicrobial drugs cefazolin and vancomycin (over about 5 and 7 days, respectively) was observed from gels containing an intermediate amount of grafts which combined reduced phase separation with a degradation time of 40 days. The degradation byproducts of one hydrogel formulation were cytocompatible to NIH 3T3 fibroblasts at concentrations up to 2.5 wt %. This class of terpolymer hydrogels is a promising local delivery system for a wide variety of drugs, particularly for applications involving irregular geometries such as implant interfaces. © 2012 Wiley Periodicals, Inc.
