Primary hypertrophic osteoarthropathy (HOA) is a rare condition with no identifiable cause, accounting for 3%–5% of all HOA cases. It is challenging to identify incomplete primary HOA, which can be misdiagnosed as other hypertrophic periostitis diseases. At least two of the four criteria set by Borochowitz and Rimoin (1990) must be present to diagnose primary HOA. Diagnostic difficulties due to incomplete or atypical manifestations are common. We present a case of incomplete primary PHOA at Hanoi Medical University Hospital in Vietnam. A 37-year-old male presented with ankle joint pain for nearly four years. X-ray and magnetic resonance imaging showed periostitis in the tibias and fibulas, which could not exclude Camurati–Engelmann disease. Finally, gene sequencing on the Illumina MiSeq system identified a missense mutation (c.295C>T) in the solute carrier organic anion transporter family member 2A1 (SLCO2A1) gene on chromosome 3. Our case report and literature review aim to improve specialists' understanding of incomplete primary HOA and reduce the frequency of missed diagnoses.
The Tangut character
'ja¹ (#1718) is usually glossed as Chin. nuò 诺 ‘(to) promise; yes’ in dictionaries. Given the fact that it does occur in rhetorical questions, this article argues that Tangut
'ja¹ is instead a constituent question particle and thus not restricted in rhetorical use. The conclusion is based on a detailed philological investigation, employing multilingual parallel texts where applicable. Comparisons with other Qiangic languages reveal several candidates for cognates. Nonetheless, their similarity is more likely to be an areal typological feature, rather than an etymological relation.
The study investigates the antimicrobial effects of the Hypericum crenulatum ethanolic (HCE) extract against 14 different food pathogens and their biofilm-forming abilities in response to HCE treatment. The phenolic acid composition of the HCE extract was also determined using an HPLC-DAD detector. The antimicrobial activity of HCE extract was assessed using the disc diffusion and microdilution methods. According to the findings, the methicillin-resistant Staphylococcus aureus ATCC 43300, Listeria monocytogenes RSKK 472, and Listeria innocua ATCC 33090 strains exhibited the lowest minimum inhibitory concentration (MIC) values at a concentration of 2 μg mL−1. Based on the disc diffusion test results, the largest zone of inhibition of HCE extract against foodborne pathogens was seen against Bacillus cereus, and the diameter of the inhibition zone increased with the concentration of HCE extract (P < 0.05). In terms of phenolic acid composition of HCE extract, the phenolic acids with the highest and lowest amounts were caffeic acid (59.92 mg g−1) and p-coumaric acid (13.61 μg g−1), respectively. Our study determined that the HCE extract demonstrated antimicrobial, bactericidal, and antibiofilm activities against some foodborne pathogens. These effects reveal its potential for improving food safety by inhibiting the growth of these pathogens.
Studies have shown evidence for long-term effects of psychedelics on personality, but comprehensive models of psychedelic-mediated personality changes have yet to be explored.
The present study aims to investigate (1) perceptions of personality change in the general population, (2) moderators of perceived personality change including setting and drug type, and (3) whether personality predisposes individuals to use psychedelics.
Paid participants with experience using psychedelic (N = 218), non-users with interest in using psychedelics (N = 104), and non-users without interest in using psychedelic (N = 104) completed an online survey following recruitment from Amazon Mechanical Turk. Psychedelic users were asked to complete written open-ended accounts of perceived personality changes that they attribute to their most intense psychedelic experience. Thematic and factor analyses were undertaken to identify themes of perceived psychedelic change and their organizational structure.
Thematic analyses resulted in 52 unique personality change themes, and exploratory factor analyses yielded eight thematic factors (Unitive Spiritual, Gratitude Absorption, Purpose Freedom, Compassion Understanding, Emotional Stability, Openness Perspective, Connection to Self, and Neuroticism Caution). Interest in psychedelic use among non-users was associated with higher openness and neuroticism. Psychedelic users tended to be more open and extraverted, and less neurotic than non-users, and interested non-users tended to be higher in openness than uninterested non-users.
The present results inform a tentative model of how personality leads to psychedelic use, how psychedelic use leads to changes in personality, and how setting and drug moderate different types of changes in personality. Research and clinical implications are discussed, including (1) hypotheses for future prospective and experimental research, (2) the value of creating multi-faceted, holistic measures that reflect the diversity and organizational structure of possible psychedelic changes, and (3) the value of allowing such evidence to guide novel psychedelic-assisted therapeutics.
The important role that the Hašt Bihišt VI of Idrīs Bidlīsī (1457–1520) and the detailed accounts he devoted to the reign of Murād II (1421–1444; 1446–1451) played in the development of early modern Ottoman historiography cannot be denied. Although the work was popular in the Ottoman world, especially its court circles, where its handsome copies were avidly produced, it was never prepared as a critical edition in its original Persian in the modern Ottoman studies departments. The following discussion concentrates on an editorial emendation that shows the carelessness of Bidlīsī in the transmission of his quotations. The formation of the Sufi and Shiite elements within Book VI of Hašt Bihišt is only briefly discussed.
Peanut butter and yoghurt are targeted for adulteration intended at consumer deception. This study aimed to fingerprint and detect peanut butter and yoghurt adulteration with cassava flour and starch using Near Infrared Spectroscopy (NIRS) in a quasi-experimental approach. Ingredients for laboratory sample preparation were obtained from the Kumasi Metropolis. Peanut butter was adulterated at 1, 3, 5, 10, 15, 20% w/w and yoghurt at 0.25, 0.5, 1, 3, 5, 10, 15, 20, 25, 45, 50% w/w. Selected concentrations mimicked practices on the market. Marketed products were randomly sampled from six markets in the Kumasi Metropolis to validate the study models. Samples were scanned with a hand-held NIRS in triplicates. Chemometric (Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA) and Partial Least Square Regression (PLSR) models) statistical methods were employed to develop classification and prediction models. Peaks with spectral bands such as 1050 , 1200 and 1450 nm were observed for peanut butter and 990–1100 nm, 1100–1200 nm and 1300–1408 nm were observed for yoghurt in the NIR spectrum. Some yoghurt brands were suspected of containing cassava starch, while Peanut butter from the different markets differed based on classification models. Cassava flour and starch concentrations were quantitatively predicted by PLSR with an R2CV of 0.98 and an error of 0.9 g/100 g (low error).
Campylobacter infections and campylobacteriosis-associated post-infectious sequelae are a significant global health burden that needs to be addressed from a specific African perspective. We conducted a comprehensive literature search on NCBI PubMed to compile a comprehensive narrative review article on Campylobacter infections in Africa, focusing on key aspects in human and veterinary medicine as well as food hygiene. We specifically focused on the epidemiology of enteropathogenic Campylobacter spp. in sub-Saharan and North Africa considering antimicrobial susceptibility. The most significant sequela resulting from molecular mimicry to Campylobacter surface structures is the Guillain-Barré syndrome, which was mainly examined in the context of limited studies conducted in African populations. A dedicated subsection is allocated to the limited research on the veterinary medically important species Campylobacter fetus. There are significant differences in the composition of the gut microbiome, especially in rural areas, which affect the colonization with Campylobacter spp. and the manifestation of campylobacteriosis. There may be a problem of overdiagnosis due to asymptomatic colonization, particularly in the detection of Campylobacter using molecular biological techniques. To reduce the colonization and infection rate of Campylobacter, we propose implementing several control measures and urge further research to improve the current understanding of the peculiarities of campylobacteriosis in Africa.
Asymptotic uniform upper density, shortened as a.u.u.d., or simply upper density, is a classical notion which was first introduced by Kahane for sequences in the real line.
Syndetic sets were defined by Gottschalk and Hendlund. For a locally compact group 𝐺, a set 𝑆 ⊂ 𝐺 is syndetic, if there exists a compact subset 𝐶 ⋐ 𝐺 such that 𝑆𝐶 = 𝐺. Syndetic sets play an important role in various fields of applications of topological groups and semigroups, ergodic theory and number theory. A lemma in the book of Fürstenberg says that once a subset 𝐴 ⊂ ℤ has positive a.u.u.d., then its difference set 𝐴 − 𝐴 is syndetic.
The construction of a reasonable notion of a.u.u.d. in general locally compact Abelian groups (LCA groups for short) was not known for long, but in the late 2000’s several constructions were worked out to generalize it from the base cases of ℤ𝑑 and ℝ𝑑. With the notion available, several classical results of the Euclidean setting became accessible even in general LCA groups.
Here we work out various versions in a general locally compact Abelian group 𝐺 of the classical statement that if a set 𝑆 ⊂ 𝐺 has positive asymptotic uniform upper density, then the difference set 𝑆 − 𝑆 is syndetic.
