The 2022 Conservative leadership campaign and post-racial gatekeeping
The Conservative party leadership contest that took place in the summer of 2022 was unprecedented for, amongst other things, its level of ethnic diversity. This paper argues that this doesnât indicate a sharp, contemporary liberal turn within the party. It argues the opposite, in fact, that recent senior ethnic minority cabinet members and leadership contenders represent some of the partyâs most right-wing ideologues in years. Through critical discourse analysis of narrative related to race, borders, immigration and the ânationâ in selected media appearances made by ethnic minority leadership contenders Rishi Sunak, Sajid Javid, Nadhim Zahawi, Suella Braverman and Kemi Badenoch as part of their campaigns, this paper positions these individuals â in distinct yet interrelated ways â as ethnic minority post-racial gatekeepers, continuing yet intensifying a long trend within the Conservative party of the reproduction of the racial status quo legitimised through nominal ethnic minority representation
The identity of Schilbe intermedius in Jebba Lake, Nigeria
This study attempts to ascertain the identity of Schilbe intermedius (Family: Schilbeidae) in Jebba Lake using quantitative (mophometric and meristic) and qualitative (colour and shape) parameters that makes identification easier. One hundred (100) specimens were collected and used for the study. There was relationship between body weight and length of fish (a=0.039, b=2.332, r=5.96). The parameters are similar to description of other authors. There is also absence of adipose fin found in the species, which is due to the geographical location
A descriptive exploration of younger and older adultsâ experiences of Integrative Medical Group Visits for Long COVID
Introduction: Long COVID disproportionately affects older adults. Individuals with Long COVID (LC) often experience symptoms that severely impact quality of life, and treatment approaches are still evolving. The Integrative Medical Group Visit (IMGV) model is an evidence-based approach that may be useful to treat patients with LC; however, there is limited evidence describing the experience and/or feasibility of using IMGV for LC treatment, especially among the older adult population. The purpose of this study is to describe older and younger adultsâ experiences of both having LC and participating in a virtually delivered IMGV for LC. Methods: This is a secondary analysis of qualitative data from a parent study examining the experiences of participants in a virtually delivered IMGV for patients with LC. Patients participated in semi-structured interviews before and after 8 weekly IMGV sessions. Thematic analysis was used to analyze interview data. Results: Overall, 21 pre-interviews and 17 post-interviews were collected. Thematic analysis of patient interviews by age group resulted in three themes that each contained similarities and differences between the younger and older adult participants. These themes included: (1) experiences of LC (2) feelings about the future (3) experiences of the pilot IMGV on LC. Conclusion: This study provides critical context for clinicians who treat older adults with LC. Results support virtually delivered IMGVs as a potentially feasible option for both older and younger adults who want to apply an integrative approach to their LC treatment. Findings from this study will inform future research on IMGV for LC treatment
Spouted bed dried Rosmarinus officinalis extract: a novel approach for physicochemical properties and antioxidant activity
In this study, a conical-cylindrical spouted bed dryer with TeflonŸ beads as spouting material was used for producing powdered rosemary (Rosmarinus officinalis L.) extract. The influence of the inlet drying gas temperature (Tgi) and the percentage ratio between the feed rate of concentrated liquid extract by the maximum evaporation capacity of the spouted bed (Ws/Wmax) on selected physicochemical properties of the finished products were investigated. Antioxidant properties of the concentrated liquid extract and dried extracts were also evaluated by the 2.2-diphenyl-1-picrylhydrazyl radical scavenging (DPPH) and lipid peroxidation induced by Fe2+/citrate (LPO) methods; and compared with the values obtained for a lyophilized extract (used as a control). Colloidal silicon dioxide (TixosilŸ 333) and maltodextrin (DE 14) at a 2:1 ratio was added to the concentrated extract before drying (4.4% w/w) to improve the drying performance. The drying variables Ws/Wmax and Tgi have statistically significant influence on total polyphenols and total flavonoid contents of the dried powders. The concentrated extract (on dry basisbeing absolute solid content) showed superior antioxidant activity (AA) compared to both the spouted bed dried and the lyophilized extracts; exhibiting IC50 values of 0.96 ± 0.02, 2.16 ± 0.04 and 3.79 ± 0.05 ”g mL1 (DPPH method) and 0.22 ± 0.01, 1.31± 0.01 and 2.54 ± 0.02 ”g mL1 (LPO method), respectively. These results of AA are comparable to values obtained for quercetin, a flavonoid compound often used as a reference standard due to its potent antioxidant activity; with IC50 of 1.17 ”g mL1 (DPPH) and 0.22 ”g mL1 (LPO). However, the dried rosemary extracts are about 13.5 times more concentrated than the initial concentrated extract (dry weight), with a concentration of total flavonoids and polyphenols compounds ranging from 4.3 to 12.3 and from 1.2 to 4.7 times higher than the concentrated extract values (wet basis). The AA per dry product mass was thus significantly higher than the values measured for concentrated extractive solution, irrespective of some losses of AA apparently due to the drying process.Foundation of Research Support of the São Paulo State

Serospatial epidemiology of zoonotic Coxiella burnetii in a cross section of cattle and small ruminants in northern Nigeria
The persistent and highly transmissible Coxiella burnetii is a neglected infection that negatively affects reproductive parameters of livestock. It is also of zoonotic importance and has been reported to cause devastating human infections globally. Domestic ruminants represent the most frequent source of human infection. Data from Nigeria are very few and outdated. There is a significant gap in up-to-date information on the exposure, spatial distribution and risk factors of infection of this important disease. The exposure to C. burnetii was determined using sensitive serological assays in cattle and small ruminants. A total of 538 animals made up of 268 cattle and 270 small ruminants were sampled from three northern Nigerian states. The proportion of cattle sampled that were seropositive from the study locations were: Kwara 14/90 (15.6%; 95% CI: 8.8â24.7); Plateau 10/106 (9.43%; 95% CI: 4.6â16.7) and Borno 4/72 (5.56%; 95% CI: 1.5â13.6) states. Lower seroprevalence was recorded among the small ruminants sampled, with positives recorded from sheep and goat sampled from only Kwara state 6/184 (3.3%; 95% CI: 1.2â7.0); while none of the small ruminants sampled from Plateau were seropositive. The results of the bivariate analysis showed that none of the tested independent variables (village, age group, sex, breed of cattle, presence of ticks, reproductive status, and management system) were statistically significant factors associated with seropositivity of cattle for antibodies to C. burnetii. Stakeholders involved in animal husbandry should be duly educated on proper disposal of birth products as well as bodily fluids in order to reduce environmental contamination, persistence and human infection
How Should Addiction-Related Research at the National Institutes of Health be Reorganized?
The decades-old debate about the optimum organizational structure of the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and National Institute on Drug Abuse (NIDA) has reached a crescendo with the recent deliberations of the Scientific Management Review Board, which, despite the lack of a crisis, proposed a structural reorganization that would dissolve the two institutes and create a new institute for substance use, abuse, and addiction, in hope of new scientific and public health advances (Collins, 2010). For a new institute to succeed, a multitude of potential challenges need to be negotiated effectivel

Quantification of the efficiency of treatment of Anopheles gambiae breeding sites with petroleum products by local communities in areas of insecticide resistance in the Republic of Benin
<p>Abstract</p> <p>Background</p> <p>The emergence of <it>Anopheles </it>populations capable of withstanding lethal doses of insecticides has weakened the efficacy of most insecticide based strategies of vector control and, has highlighted the need for developing new insecticidal molecules or, improving the efficacy of existing insecticides or abandoning those to which resistance has emerged. The use of petroleum products (PP) against mosquito larvae had an immense success during early programmes of malaria control, but these compounds were abandoned and replaced in the 1950s by synthetic insecticides probably because of the high performances given by these new products. In the current context of vector resistance, it is important to elucidate the empirical use of PP by quantifying their efficiencies on resistant strains of <it>Anopheles</it>.</p> <p>Methods</p> <p>Larvae of <it>Anopheles </it>Ladji a local resistant strain were exposed to increasing concentrations of various PP (kerosene, petrol and engine oils) for 24 hours and the lethal activities recorded. The highest concentration (HiC) having no lethal activity (also referred as the NOEL or no effect level) and the lowest concentration (LoC<sub>100</sub>) yielding 100% mortality were rated for each PP on the Ladji strain. Prior to laboratory analysis, KAP studies were conducted in three traditional communities were insecticide resistance is clearly established to confirm the use of PP against mosquitoes.</p> <p>Results</p> <p>Laboratory analysis of petrol, kerosene and engine oils, clearly established their lethal activities on resistant strains of <it>Anopheles </it>larvae. Contrary to existing references, this research revealed that exposed larvae of <it>Anopheles </it>were mostly killed by direct contact toxicity and not by suffocation as indicated in some earlier reports.</p> <p>Conclusion</p> <p>This research could serve as scientific basis to backup the empirical utilisation of PP on mosquito larvae and to envisage possibilities of using PP in some traditional settings where <it>Anopheles </it>have developed resistance to currently used insecticides.</p
