En el siguiente texto realizamos una revisión de los estudios que tienen el concepto de cultura popular como punto de referencia, junto a otros como el de cambio social y el de identidad, realizados por la antropología española durante las últimas décadas del siglo XX. A través de los diversos tipos de estudios y los paradigmas utilizados podremos tener una visión de conjunto del desarrollo de la disciplina antropológica durante dicho período en el contexto español, así como de la elección de determinados temas, a veces exportados y recreados dentro del seno de la disciplina en el propio territorio, que marcarían el debate antropológico en la época.
In this text we make a revision of the studies carried out by Spanish Anthropology during the last decades of the 20th Century. These studies have the concept of popular culture as a reference point, next to others such as those of social change and identity. Through the different types of studies and the paradigms used we will be able to have an overall vision of the development of the Anthropological discipline in that period in the Spanish context, as well as a vision of the choice of certain topics, which would mark the Anthropological debate in that period. These topics were sometimes exported and recreated inside the discipline in our country.

Introduction
Colorectal cancer screening program compliance in Turkey is around 20–30%. Factors that may affect preventive health behavior, mainly individuals’ values, beliefs and attitudes, should be explored. A “Health Belief Model” (HBM) scale was developed in 1950 to explain the insufficient participation of some individuals in screening programs. The scale was adopted for colon cancer in 2002. The validity and reliability study of this scale for the Turkish language was conducted in 2007. In this study we aim to evaluate the health beliefs of relatively young individuals before the age of screening in relation to attitudes to colorectal cancer screening via the Turkish version of the scale.

Materials and Methods
A questionnaire composed of 14 sociodemographic questions and 33 HBM scale questions were applied to the patients of a Family Medicine outpatient clinic where the majority of the patients are relatively young people. The data was analyzed using the IBM SPSS version 21.0.

Results
A total of 310 subjects at the age of 18 and over were informed about the study. The study was completed with 215 subjects with a participation rate of 69.3%. The average age of the participants was 35.4 ± 12.8 years; 62.8% of them were women; 26.0% were students. 94.4% of the participants did not have a history of colon cancer among their first degree relatives. 58.1% agreed that “A colonoscopy should be done every ten years starting at age 50 to screen for colon cancer.” Age, marital status, education and occupation status were found to have an effect on barrier scores. Young participants, singles, and those with a primary and/or secondary school education had statistically significant higher barrier scores. The motivation scores of high school graduates were higher than university graduates. The seriousness scores of men were found to be higher than women.

Conclusion
Our study points out that attitudes about preventive health measures are mainly associated with age, gender, education level and marital status. These personal characteristics should be taken into consideration while offering screening programs and preventive health measures to individuals in order to protect against colorectal cancer. It is better to give specific messages according to personal characteristics and specific barriers instead of general messages about conducting screening tests beginning from a young age.

Aim: The pesticide pollution of aquatic ecosystems has developed serious environmental anxiety, provoking a necessity for continuous evaluation of harmful constituents.
Study Design: A quantitative cum descriptive experimental design was used to evaluate the occurrence and concentration of Persistent Organochlorine Pesticides (POPs) in water, sediment, fish (Tilapia zilli and Chrysichthys nigrodigitatus) and shell fishes (Macrobrachium vollenhovenii, Littorina littorea and Callinectes pallidus) of River Majidun, Lagos, Nigeria.
Place and Duration of Study: Nigerian Institute of Oceanography and Marine Research (NIOMR) between June and December, 2019.
Methodology: Sediment samples were collected by the Rigosha grab sampler and fish samples were purchased from commercial fishermen. Sample preparation was done according to the Environmental Protection Agency (US EPA) 3570 method. POPs were evaluated using Hewlett Packard 5890 series II gas chromatography with electron capture detector.
Results: Twenty-one organochlorine residues were identified including p’p’DDT, Lindane (γ-HCH), Dieldrin, Heptachlor, Aldrin, Chlordane, Endrin aldehyde, Endrin ketone, Methoxichlor and Endosulphan. Concentrations in water ranged between 0.03 µg l-1 (Endrin ketone) and 1.97 µg l-1 (Methoxychlor). In sediment, it is between 4.55 µg kg-1 (β-HCH) and 128.25 µg kg-1 (Methoxychlor). In Macrobrachium vollenhovenii, Methoxychlor was 123.83 µg kg-1 and Lindane ((γ)- HCH) was highest here (39.35 µg kg-1). Callinectes pallidus had a high concentration of Endrin ketone (133.13 µg kg-1). The Tilapia zilli highest concentration was 110.35 µg kg-1 (endrin ketone) and it had the highest pp’DDT which was 41.40 µg kg-1.
Conclusion: Evidently, there was sequestration of POPs from water into sediment and bioaccumulation in the organisms, due to exposure. The level of POPs in all samples were below the limits of 200 µg kg-1 fresh weight in fish and sea food set by Codex Alimentarius Commission by FAO/WHO. The attendant environmental/human menace cum inherent danger of the raised levels of POPs, calls for continuous monitoring of River Majidun.
Anaerobic Digestion of Corn Stover for Improved Biomethane Yield: Effect of Organic Nitrogen Sources (Soybean Curd Residue and Fish Waste)
Authors: Opurum C. C. , Odibo F. J. C. 
Published: March 2021

The present study investigated the effect of organic nitrogen sources, soybean curd residue (SCR), and fish meal (FW) on the anaerobic digestion of corn stover for biomethane production. The bioreactors were seeded with the corn stover (corn cob and corn sheath), soybean curd residue (SCR), and fish waste (FW) at different combinations: (CC/SCR), (CC/FW), (CS/SCR) and (CS/FW), including CC and CS alone. The fermentation was for 31 days under mesophilic conditions. Characteristics of the substrates indicate that CC and CS are good carbon and energy sources, but low in nitrogen content. Conversely, SCR and FW are rich nitrogen sources, with low organic carbon content. There was a remarkable increase in biogas production in all treatments, except CC/SCR 75:25 and CC/SCR 85:15 in which inhibitory effect was observed. The highest percentage increase (138%) in biogas was recorded in CS/SCR 85:15 (2.86 dm3), and the least was CC/FW 75:25 with 1.49 dm3 (24.18% increase). Significant difference (P ≤ 0.05) in biogas yield was in the following: CC/SCR 50:50, CC/FW 50:50, CS/SCR 85:15, CS/FW 50:50, and CS/FW 75:25. The composition of the biogas revealed that the treatment improved biogas production as well as biomethane content, the highest being 69.44% in CS/SCR 85:15. Regression analysis of cumulative biogas yield as a function of time (t) in the different treatments that had a significant difference in biogas yield showed a good correlation between biogas yield (GY) and time (t). Improving the biodegradability of lignocellulosic wastes could lead to a boost in the development of anaerobic digestion and biogas production technology. To improve their biodegradability during anaerobic digestion, both pre-treatments and supplementation have vital roles to play.

AbstractReactive oxygen species (ROS/RNS) are produced during inflammation and elicit protein modifications, but the immunological consequences are largely unknown. Gas plasma technology capable of generating an unmatched variety of ROS/RNS is deployed to mimic inflammation and study the significance of ROS/RNS modifications using the model protein chicken ovalbumin (Ova vs oxOva). Dynamic light scattering and circular dichroism spectroscopy reveal structural modifications in oxOva compared to Ova. T cells from Ova‐specific OT‐II but not from C57BL/6 or SKH‐1 wild type mice presents enhanced activation after Ova addition. OxOva exacerbates this activation when administered ex vivo or in vivo, along with an increased interferon‐gamma production, a known anti‐melanoma agent. OxOva vaccination of wild type mice followed by inoculation of syngeneic B16F10 Ova‐expressing melanoma cells shows enhanced T cell number and activation, decreased tumor burden, and elevated numbers of antigen‐presenting cells when compared to their Ova‐vaccinated counterparts. Analysis of oxOva using mass spectrometry identifies three hot spots regions rich in oxidative modifications that are associated with the increased T cell activation. Using Ova as a model protein, the findings suggest an immunomodulating role of multi‐ROS/RNS modifications that may spur novel research lines in inflammation research and for vaccination strategies in oncology.

AbstractPowder to bulk processes, such as additive manufacturing and metal injection molding (MIM), have enabled great potential for complex metal designing and manufacturing. However, additive manufacturing process normally introduces a high residue stress and textures due to the locally intense temperature. MIM is an excellent batch manufacturing process; nevertheless, it is not suitable for rapid screening and development of new metal compositions and structures due to the slow sintering process. Herein, an ultrafast high‐temperature sintering (UHS) process is reported that enables the rapid synthesis and sintering of bulk metals/alloys and intermetallic compounds. In this process, elemental powders are mixed and pressed into pellets, followed by UHS sintering in just seconds at a temperature between 1000 and 3000 °C. Three representative compositions, including pure metals, intermetallics, and multielement alloys, are demonstrated with a broad range of melting points. The UHS process for metal sintering is nonmaterials specific, in addition to being extremely rapid, which make it suitable for materials discovery. Furthermore, the sintering method does not apply pressure to the samples, making it compatible with 3D printing and other additive manufacturing processes of complex structures. This rapid sintering technique will greatly facilitate the development and manufacturing of metals and alloys.

AbstractField pennycress (Thlaspi arvense L.) (PC) and winter camelina [Camelina sativa (L.) Crantz] (WC) have the potential to provide ecosystem services and economic incentives when adopted as an oilseed cover crops in corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotations. However, PC and WC establishment and yield in the northern Corn Belt and their subsequent impact on row crops are not well known. This study was conducted to determine the effects of interseeding dates (R4, R5, and R6; and R6, R7, and R8 development stages for corn and soybean, respectively) and cover crop species (PC, WC, and winter rye [Secale cereale L.]) on seed yield and oil content of interseeded oilseeds (PC and WC) and relay soybean, and 3rd‐year corn grain yield and quality. Study sites were initiated near Ames, IA; Morris and Rosemount, MN; and Prosper, ND. Late interseeding of PC and WC resulted in greater oilseed yield. Overall yields of PC (218–880 kg ha–1) and WC (15–770 kg ha–1), averaged across interseeding dates, were low when interseeded in corn and soybean. The PC and WC reduced relay‐soybean grain yield by 13–32% and 13–42%, respectively. Corn grain yield and quality following relay soybean were not affected by the residual effects of oilseed cover crops. Based on the results of our study, we do not recommend relay cropping soybean with PC and WC in the upper Midwest.

AbstractInguinal hernias are common diseases, but malignant lesions in groin hernias are rare; metastatic hepatocellular carcinoma (HCC) in the hernia sac is extremely rare. We report a 72‐year‐old man who had advanced stage HCC with portal vein invasion and multiple metastatic lymphadenopathies. He presented a painless palpable mass in the right groin. Computed tomography scan showed a contrast‐enhanced soft tissue mass (2.8 cm in size) at the right herniated inguinal sac. Tumor excision and hernia repair were performed, and the histopathological examination revealed metastatic HCC. After being stabilized from surgery, the patient received combination therapy with sorafenib and nivolumab; however, he still died of rapid tumor progression and liver decompensation 1 month later. This case raises clinical awareness of unusual extrahepatic metastases of HCC, especially for patients at an advanced tumor stage.

AbstractCompared to the current mainstream rigid covalent organic frameworks (COFs) linked by imine bonds, flexible COFs have certain advantages of elasticity and self‐adaptability, but their construction and application are greatly limited by the complexity in synthesis and difficulty in obtaining regular structure. Herein, we reported for the first time a series of flexible amine‐linked COFs with high crystallinity synthesized by formic acid with unique catalytic and reductive bifunctional properties, rather than acetic acid, the most common catalyst for COF synthesis. The reaction mechanism was demonstrated to be a synchronous in situ reduction during the formation of imine bond. The flexibilities of the products endow them with accommodative adaptability to guest molecules, thus increasing the adsorption capacities for nitrogen and iodine by 27 % and 22 %, respectively. Impressively, a novel concept of flexibilization degree was proposed firstly, which provides an effective approach to rationally measure the flexibility of COFs.

AbstractThe receptor binding domain (RBD) of the spike glycoprotein of the coronavirus SARS‐CoV‐2 (CoV2‐S) binds to the human angiotensin‐converting enzyme 2 (ACE2) representing the initial contact point for leveraging the infection cascade. We used an automated selection process and identified an aptamer that specifically interacts with CoV2‐S. The aptamer does not bind to the RBD of CoV2‐S and does not block the interaction of CoV2‐S with ACE2. Nevertheless, infection studies revealed potent and specific inhibition of pseudoviral infection by the aptamer. The present study opens up new vistas in developing SARS‐CoV2 infection inhibitors, independent of blocking the ACE2 interaction of the virus, and harnesses aptamers as potential drug candidates and tools to disentangle hitherto inaccessible infection modalities, which is of particular interest in light of the increasing number of escape mutants that are currently being reported.

Published: March 2021

AbstractAdvanced porous materials (APMs)—such as metal‐organic frameworks (MOFs) and porous organic polymers (POPs)—have emerged as an exciting research frontier of chemistry and materials science. Given their tunable pore size and extensive diversity, APMs have found widespread applications. In addition, adding dynamic functional groups to porous solids furthers the development of stimuli‐responsive materials. By incorporating moving elements—molecular rotors—into the porous frameworks, molecular‐rotor‐driven advanced porous materials (MR‐APMs) can respond reversibly to chemical and physical stimuli, thus imparting dynamic functionalities that have not been found in conventional porous materials. This Minireview discusses exemplary MR‐APMs in terms of their design, synthesis, rotor dynamics, and potential applications.

AbstractPeroxidized phosphatidylethanolamine (PEox) species have been identified by liquid chromatography mass spectrometry (LC‐MS) as predictive biomarkers of ferroptosis, a new program of regulated cell death. However, the presence and subcellular distribution of PEox in specific cell types and tissues have not been directly detected by imaging protocols. By applying gas cluster ion beam secondary ion mass spectrometry (GCIB‐SIMS) imaging with a 70 keV (H2O)n+ (n>28 000) cluster ion beam, we were able to map PEox with 1.2 μm spatial resolution at the single cell/subcellular level in ferroptotic H9c2 cardiomyocytes and cortical/hippocampal neurons after traumatic brain injury. Application of this protocol affords visualization of physiologically relevant levels of very low abundance (20 pmol μmol−1 lipid) peroxidized lipids in subcellular compartments and their accumulation in disease conditions.
How students use deliberate practice during the first stage of counsellor training
Authors: McLeod Julia 
Published: March 2021

AbstractDeliberate practice, in the form of ongoing commitment to skill development outside of direct clinical work, has been proposed as a means of enhancing therapist competence and expertise. In this study, a deliberate practice orientation was introduced into the first phase of a counsellor training programme. Students’ experiences of learning and using deliberate practice in relation to the acquisition of counselling skills were investigated using a mixed‐method design. It took time for students to internalise principles of deliberate practice. They reported a wide range of deliberate practice learning activities, both within and beyond the classroom, and regarded these tasks as having made a significant positive contribution to their learning. The findings of the study underscore the value of viewing deliberate practice as an approach to learning that can be articulated in multiple ways. It is important for future research to identify the forms of deliberate practice that are most relevant to enhancing competence within the specific context of therapeutic work.

AbstractThe clustered regularly interspaced short palindromic repeats (CRISPR) technology has been widely applied for nucleic acid detection because of its high specificity. By using the highly specific and irreversible bond between HaloTag and its alkane chlorine ligand, we modified dCas9 (deactivated CRISPR/Cas9) with biotin as a biosensor to detect nucleic acids. The CRISPR biosensor was facilely prepared to adequately maintain its DNA‐recognition capability. Furthermore, by coupling biolayer interferometry (BLI) with the CRISPR biosensor, a real‐time, sensitive, and rapid digital system called CRISPR‐BLI was established for the detection of double‐stranded DNA. The CRISPR biosensor immobilised on the biolayer could recruit the target DNA onto the biosensor surface and change its optical thickness, resulting in a shift in the interference pattern and responding signal of the BLI. The CRISPR‐BLI system was further applied to detect the ALP gene of Escherichia coli DH5α combined with a polymerase chain reaction, which demonstrated a linear range from 20 to 20 000 pg and a low detection limit (1.34 pg). The CRISPR‐BLI system is a promising approach for rapid and sensitive detection of target DNA analytes.

AbstractBio‐derived furan‐ and diacid‐derived cyclic carbonates have been synthesized in high yields from terminal epoxides and CO2. Furthermore, four highly substituted terpene‐derived cyclic carbonates were isolated in good yields with excellent diastereoselectivity in some cases. Eleven new cyclic carbonates derived from 10‐undecenoic acid under mild reaction conditions were prepared, providing the corresponding carbonate products in excellent yields. The catalyst system also performed the conversion of an epoxidized fatty acid n‐pentyl ester into a cyclic carbonate under relatively mild reaction conditions (80 °C, 20 bar, 24 h). This bis(cyclic carbonate) was obtained in high yields and with different cis/trans ratios depending on the co‐catalyst used. An allyl alcohol by‐product was only observed as a minor product when bis(triphenylphosphine)iminium chloride was used as co‐catalyst. Finally, two cyclic carbonates were used as building blocks for the preparation of non‐isocyanate poly(hydroxy)urethanes by reaction with 1,4‐diaminobutane.
