Vendian of the eastern flank of the Avdyrdak anticline of the Alatau anticlinorium (Southern Urals)
Authors: Sergeeva Nina Dmitrievna , Dyakova Svetlana Andreevna
Published: April 2023

Object of study. Deposits of the Asha series of the Vendian of the eastern flank of the Avdyrdak anticline, divided by a meridional fault into two monoclinal blocks, in which researchers give different stratigraphic interpretations of the sections. Results. A study was made of the deposits of the Asha series of the eastern flank of the Avdyrdak anticline along the highway (80K-031) Ufa–Beloretsk, where these deposits are most fully exposed by road cuttings and quarries. Detailed descriptions and sketches of fragments of the sediment section are given, the lithological and petrographic composition of the rocks, their ratio and thickness in the sections of the western and eastern tectonic blocks are specified. Conclusions. It has been established that according to the lithologic-petrographic composition of the rocks and the structure of the sections of the Asha series of the Vendian of the eastern flank of the Avdyrdak anticline along the highway (80K-031) Ufa-Beloretsk, the western and eastern tectonic blocks of the structure are composed of deposits of the Basa, Kukkarauk and Zigan formations. The stratigraphic similarity of the sections of the western and eastern tectonic blocks of the eastern flank of the Avdyrdak anticline indicates the thrust character of tectonic movements.
P-T parameters of metamorphism of the rocks of the differentiated body of the Misaelga complex (western slope of the Southern Urals)
Authors: Kovalev Sergei Grigor’evich , Kovalev Sergei Sergeevich
Published: April 2023

The article presents materials on the P-T parameters of metamorphism of the rocks of the differentiated body of the Misaelga complex. Based on the study of metamorphogenic minerals and mineral associations: amphibole, amphibole-plagioclase, amphibole-garnet, epidote-garnet, muscovite, chlorite, ilmenite-titanomagnetite, a gradual decrease in temperature and pressure was established from the final stages of the magmatic stage of formation of rocks of the Misaelga complex to the beginning of the metamorphogenic stage.

It is shown that the process of amphibolization begins immediately when the temperature of the residual melt drops by ~100°С (from 800°С to 700°С), which indicates the autometamorphic character of rock alteration. At the same time, the decomposition of the solid solution in titanomagnetite and ilmenite begins (766–588°С). Further changes include alteration (albitization) of plagioclase (550–>400°С), sericitization (~ 300°С) and chloritization (333–157°С).

The association of minerals with garnet, distributed in a narrow interval of the section at a depth of 341.5 m with a horizon thickness of no more than 2–2.5 m, is a zone in which dynamothermal metamorphism manifested itself, due to fluid working out of the substrate of the Taratash complex in shear deformation zones, identified in the interval 1400–1200 Ma. The P-T parameters of dynamothermal metamorphism, determined by the garnet-epidote association, correspond to 550–580°С at a pressure of 2 kbar, and according to the garnet-amphibole geobarometer – 300–400°С. At the same time, it should be emphasized that these associations characterize the regressive stage of metamorphism.

Differential response patterns to personality measures in the first and second languages: Cultural frame switching and cultural accommodation in bilingual speakers
Authors: Nguyen Phuong Linh Le , Chaplin William F.
Published: April 2023

Research on the effect of cultural cues, such as language, on response patterns to personality measures of bilingual speakers has produced contradictory results. However, previous research was constrained by small sample sizes that were limited to either English-Spanish or English- Chinese bilingual speakers. The current research included bilingual speakers from four different language pairs and examined whether differences in personality scores between the languages would align with differences in social desirability ratings of those personality traits in their two associated cultures. In examining each of the four language pairs, we found contradictory and weak support for the phenomenon of cultural frame switching or accommodation. Moreover, English-Chinese and English-German pairs showed opposite effects, in which a trait that was rated as less desirable in a culture was endorsed more highly in the associated language. Secondly, we looked at the aggregated data across all specific languages to examine first-versus- second-language effects. When we controlled for relevant covariates in language acquisition, language fluency was the strongest predictor of the valence of personality scores: holding other variables constant, fluent participants reported more positive personality profiles – high Agreeableness, Conscientiousness, and Openness – compared to participants with lower reported language proficiency.
Organizational Injustice and Burnout: The Moderating Role of Trait Mindfulness
Authors: Tynan Mark , Karl Johannes Alfons
Published: April 2023

This study aimed to explore the potential buffering effect of trait mindful acceptance and the exacerbating effect of trait mindful attention monitoring on the relationship between organizational injustice and burnout. A cross-sectional survey was conducted with 139 employees who completed measures of burnout, organizational injustice, and trait mindfulness. A moderated regression analysis was used to examine the relationships between burnout (DV), organizational injustice (IV), trait mindful acceptance and trait mindful attention monitoring (moderators). The results revealed a significant positive association between organizational injustice and burnout (β = .51, standardized 95% CI [.35, .67], p < 0.001) with an R2 = .26. However, trait mindful acceptance did not significantly buffer the relationship between organizational injustice and burnout (β = -.05, standardized 95% CI [-.21, .1], p = .49), while mindful attention monitoring did not significantly exacerbate impact organizational injustice on burnout (β = -.03, standardized 95% CI [-.17, .11], p = .65) with the adjusted R2 = .57. The results, while not significant, suggest that trait mindful acceptance may not buffer against the impact of organizational injustice on burnout, though trait mindful attention monitoring may indeed exacerbate this relationship. Alongside contributing to psychological theory such as Monitoring and Acceptance theory, the current study provides a unique framework for combating the negative impact of organizational injustice on burnout in the workplace. Keywords: Trait Mindfulness, organizational injustice, burnout
Corporeal Corporations: People Construe Companies as Having a Mind and Body When Allocating Blame
Authors: Sharma Nirupika , Flores-Robles Grace , Gantman Ana P.
Published: April 2023

In cases of corporate wrongdoing, it is difficult to assign blame across multiple agents who played different roles. We propose that people have dualist ideas of corporate hierarchies: with the boss as “the mind,” and the employee as “the body,” and the employee appears to carry out the will of the boss like the mind appears to will the body (Wegner, 2003). Consistent with this idea, three experiments showed that moral responsibility was significantly higher for the boss, unless the employee acted prior to, inconsistently with, or outside of the boss’s will. People also judge the actions of the employee as mechanistic (“like a billiard ball”) when their actions mirror the will of the boss. This suggests that the same features that tell us our minds cause our actions, also facilitate the sense that a boss has willed the behavior of an employee and is ultimately responsible for bad outcomes in the workplace.
Evaluation of Psychometric Properties and Inter-test Associations for Three Popular Measures of Social Competence
Authors: Jouravlev Olessia , Mahowald Kyle , Paunov Alexander , Gibson Edward , Fedorenko Evelina
Published: April 2023

A number of behavioral tools are used to assess variability in individuals' social functioning. However, it is often unclear what determines the choice of one test over the others. We here asked whether three popular tools – the Autism Spectrum Quotient (AQ; Baron-Cohen, Wheelwright, Skinner, Martin, & Clubley, 2001b), the Reading the Mind in the Eyes Test (RMET; Baron-Cohen, Wheelwright, Hill, Rate, & Plumb, 2001a), and the Reading the Mind in the Films Test (RMFT; Golan et al., 2006) – can be treated as interchangeable for social functioning assessment. The RMET and RMFT scores were strongly correlated with each other but did not correlate with the overall AQ scores (although two subscales of the AQ – imagination and communication/mindreading – correlated reasonably well with RMET and RMFT). These results suggest that the AQ is not interchangeable with RMET or RMFT as they appear to tap different aspects of social competence.

Authors: Aryal Eliz , Khadka Anupa , Bhattarai Sabeena
Published: April 2023

Background: Melasma is a disorder of acquired facial hyperpigmentation, typically affecting young females. It is known to cause a great psychological impact and a significant negative effect on a patient’s quality of life. Objectives: To explore the correlation between the quality of life in melasma patients and the severity of melasma. Methods: This hospital-based, analytical, cross-sectional study was conducted from 2020 October to 2021 December in the Department of Dermatology, Venereology and Leprology of Kathmandu Medical College after institutional ethical clearance, in 101 patients recruited by convenience sampling. The quality of life was calculated using the Nepali version of the Dermatology Life Quality Index (DLQI) questionnaire and severity of melasma was calculated using modified Melasma Area and Severity Index (mMASI). Data analysis was done by SPSS v.24. Results: The study included 101 patients of melasma with a young female preponderance. Seventy-eight (75.7%) being female and 43 (42.6%) being between the age of 21-30 years. The mean DLQI score was 10.39 ± 3.22; interpreted as having a ‘very large effect on a patient’s life.’ While the mean mMASI score was calculated to be 5.53 ± 2.69; interpreted as a melasma severity score (MSS) of ‘moderate severity.’ A significant positive moderate correlation r = 0.431 (p <0.001) was observed between mMASI and DLQI. Conclusion: Melasma is a common pigmentary disorder that has a very large effect on the patient’s quality of life and this correlates directly with the severity of melasma.

Published: April 2023

Background Acute cholecystitis is one of the commonest surgical disease. The rapid diagnosis at its early stage is one of the crucial factor in patient care and management.

Objective To evaluate the role of magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography (MRCP) in the diagnosis or exclusion of acute cholecystitis, coexisting choledocholithiasis, and acute pancreatitis in emergency setting.

Method This study was conducted in the department of radiodiagnosis B&C teaching hospital, Birtamod, Nepal from July 2016 to November 2019. Patients, clinically diagnosed as acute cholecystitis or biliary condition with positive Murphy’s sign with or without jaundice and deranged Liver Function Test, raised Leucocyte counts were evaluated by Magnetic Resonance imaging. The sensitivity, specificity, Positive Productive Value (PPV), Negative Productive Value (NPV) were calculated for the diagnosis of acute cholecystitis. Data was entered and analysed by using SPSS version 20.

 Result There were 40 patients included in our study. Among them 27 (67.5%) were females and 13 (32.5%) male. The age of the patients ranged from 16 years to 79 years, mean age 49.4 years. Majority of the patients were in the age group of 40-60 years (57.5%). The overall sensitivity, specificity, Positive Productive Value and Negative Productive Value of Magnetic Resonance imaging diagnosis of acute cholecystitis were 100%, 66.6%, 94.4% and 100% respectively. Acute cholecystitis associated with gall stone disease were common and found in 72.5% cases, with sensitivity 96.5%, specificity 27.7%, Positive Productive Value 77.7% and Negative Productive Value 75.0%.

Conclusion Magnetic resonance imaging (MRI)/Magnetic resonance cholangiopancreatography (MRCP) is an excellent tool for the evaluation of biliary pathology and can be used for the preoperative evaluation of acute cholecystitis at the emergency setting.

Published: April 2023

Background Severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) variants, which have emerged due to several mutations in spike protein, have a potential to escape immune protection provided by the first-generation vaccines, thereby resulting in breakthrough infections.

Objective To identify the socio-demographic factors, clinical features, and outcomes in both vaccinated and unvaccinated hospitalized patients infected with SARS-CoV-2.

Method Socio-demographic details, clinical features, and the outcomes among fully vaccinated (double for Covishield/AstraZeneca and BBIBP-CorV and single for Janssen), partially vaccinated, and unvaccinated hospitalized patients with coronavirus disease of 2019 (COVID-19) were collected and analyzed using SPSS version 17.

Result Among the hospitalized COVID-19 patients (n=299), 175 (58.5%) patients received a single-dose, 82 (27.4%) double-dose, and 124 (41.5%) did not receive any dose of the COVID-19 vaccines. The risk of SARS-CoV-2 infection when compared between vaccinated and unvaccinated patients was found to be associated among professional degree holders (23.4% versus 9.7%) (p<0.05), professional workers (43.4% vs. 25.0%) (p<0.05), hospitalization to general ward (76.6% vs. 72.6%) (p<0.05), and presence of multiple symptoms (≥3) (86.8% vs. 75.0%) (p>0.05) and comorbidities (≥2) (15.5% vs. 13.7%) (p>0.05). Despite such approximate incidences, the risk of in-hospital mortality among the vaccinated patients was reduced (0.6% vs. 3.2%) (p>0.05), when compared to the unvaccinated patients. The risk of in-hospital mortality was associated with the older age and the presence of multiple comorbidities including bronchial asthma, diabetes, and hypertension.

Conclusion Full or partial vaccination against the SARS-CoV-2 variants of concerns might be effective in preventing in-hospital mortality among COVID-19 patients.

Published: April 2023

Hypocalcaemia of various origin can be manifested by paresthesia, muscle cramps, muscle weakness, syncope, convulsions and even severe psychomotor retardation. Such symptoms can be initially considered as signs of epilepsy. We present a 12-year old boy with partial seizures and basal ganglia calcifications, initially diagnosed as having Fahr´s disease and epilepsy, where severe hypocalcaemia, due to genetically confirmed pseudohypoparathyroidism type Ib was the underlying cause. Excellent clinical improvement was observed after calcium and vitamin D therapy. The basal ganglia calcifications were secondary due to chronic hypocalcaemia, therefore the appropriate diagnosis was pseudohypoparathyroidism type Ib with Fahr´s syndrome, but not Fahr´s disease. In conclusion, the serum evaluation of minerals, especially calcium and phosphate, should be performed in all patients with convulsions, cramps and psychomotor retardation. This is essential in arriving at a proper diagnosis and early initiation of appropriate treatment.

Published: April 2023

Fraser syndrome (FS, MIM 219000) is a rare autosomal disorder characterized by systemic and oro-facial malformation, usually comprising cryptophthalmos, laryngeal malformations, syndactyly, and urogenital defects. We presented a 21-year-old FS case with partial missing teeth seeking aesthetic dental treatment. Clinical examination revealed bilateral cryptophthalmos, extensive syndactyly of hands and feet broad nose with the depressed nasal bridge, and surgically corrected bilateral cleft lip. She presented class III jaw relation and reduced the vertical height of the face. Prosthetic rehabilitation of the patient was done with upper and lower overlay dentures made from acrylic resin (VIPI BLOCK TRILUX®, VIPI Industria, Pirassununga, SP, Brazil) using computer-aided design (CAD) and computer-aided manufacturing (CAM) process. At the follow-up visit, the patient presented improved aesthetics and function. Proper management and rehabilitation of FS patients are challenging, but standard guidelines for oral health management are currently lacking. This article presents a case of Fraser syndrome presenting oral and craniofacial anomalies, and prosthetic rehabilitation was done. We also provided recommendations for the optimal oral health care for the FS patients. Functional adaptation and rehabilitation have significant roles in the various functions, survival, and quality of the life of FS patients. Integrated medical-dental care is needed in such patients with support from family members, friends, and colleagues.
Dimensions of Religiosity and the Perception of the Importance of Religion in Everyday Life and Politics
Authors: Jankowski Mateusz
Published: April 2023

The Catholic religion has been inextricably connected with the Polish state through numerous historical experiences. Being an important aspect of connecting society, it can be used in an instrumental way on the political agenda. Moreover, religiousness is an important determinant of electoral decisions. The aim of the research (N=238) is to check whether religiosity affects the perception of the importance of religious principles in everyday life and religion in political life. In the presented approach, religiosity was a multidimensional variable and was conceptualized using a modified five-point Religiosity Centrality Scale (Huber 2003). It was confirmed that all dimensions of religiosity are significantly related to the assessment of the importance of religious principles. The dimension that showed the strongest correlation with the created variables was the dimension of religious cult, and the dimension that correlated the least was the dimension of reading the Catholic press.

Characterization of amylase, lipase and xylanase produced by actinobacteria cultivated in licuri [Syagrus coronata - (Martius) Beccari] residues
Authors: Aguiar Milena Santos , Carvalho Andrea Limoeiro , Oliveira Elizama Aguiar
Published: April 2023

In order to seach for different microbial sources of enzymes, Arthrobacter polychromogenes CDPI-30 and Streptomyces violaceoruber CDPA-32 were individually cultivated in licuri [Syagrus coronata - (Martius) Beccari] residues. It was possible to detect some enzymes but amylase, lipase and xylanase were selected for a basic characterization. The optimum conditions were observed at pH 6 and 7 and 40 – 70 °C for amylases, pH 4 – 6 and 50 – 90 °C for lipases and pH 8 and 10 and 20 – 50 °C for xylanases. The best stabilities, evaluated under different conditions were, in a way, a result from the optimal conditions. Additionally, substrate saturation was not observed for soluble starch and xylan until 15 mg/mL and p-nitrophenyl palmitate until 9.95 µmol/mL. These results indicate that both, actinobacteria and the agroindustrial residues, are good choices to produce basic industrial enzymes.
Influence of natural conditions of southern Dagestan on formation of food substances in fruits of Golden Delises apples
Authors: Huseynova B. M. , Daudova T. I.
Published: April 2023

The results of studying the amino acid composition, macroand microelements, vitamins and other food substances in Golden Delicious apples grown in terroirs located at various altitudes above sea level in the south of Dagestan are presented in order to determine cultivation sites with natural conditions contributing to the greatest accumulation of these valuable components in fruits. The elemental composition of apples was studied using flame and atomic absorption photometry, mass concentrations of amino acids by HPLC methods, the content of sugars, titrated acids, pectins and vitamin C – titrimetrically, phenols and vitamin P colorimetrically. It was found that natural factors of the fruit zone located on the plain cause a high concentration of sugars in Golden Delicious apples – 11,3 %, soluble dry substances – 14,9 % and minerals: potassium (135.5 mg%), calcium (19.0 mg%), sodium (25.6 mg%), magnesium (12.6 mg%) and iodine (2.4 μg%), and the climatic conditions of the foothills are favorable for the synthesis of titrated acids (0,51%), vitamins C (6,8 mg %) and P (63,1 mg %), phenolic (362,1 mg %) and pectin substances (0,83 %), as well as iron, zinc and copper. The difference in the formation of minerals in apples, depending on natural conditions and the altitude gradient of the place of growth, was: for potassium – 7,2; sodium –   8,2; calcium – 9,5; magnesium – 9,4; iron – 10,9; copper – 10,2; zinc – 9,3, iodine – 8,3 %. The total amount of amino acids in apples, depending on the culture site, ranged from 683,2 to 696,9 mg/dm3. In fruits from the foothills, the total mass concentrations of replaceable and essential amino acids were 1,3 and 5,9% higher, respectively, than in apples grown on the plain. The results of the study can be taken into account in the rational use of agroecological resources of fruit zones that differ in soil-climatic conditions and altitude gradient, as well as to reveal the biological potential of the Golden Delicious apple variety.
Primary non-Hodgkin’s lymphoma of the superficial branch of the radial nerve: illustrative case
Authors: Lukins Timothy R. , Low Julia P. , Campbell Ashlea K. , Winder Mark J.
Published: April 2023

BACKGROUND

Lesions of the peripheral nervous system are many and varied. They range from benign to malignant, and determining risk can be challenging. Primary lymphoma of the peripheral nerve (PLPN) is a rare and malignant pathology. When recognized early, appropriate therapy can be delivered. The authors performed a systematic review of PLPNs and present the first case of a PLPN involving the superficial branch of the radial nerve.

OBSERVATIONS

The authors present the clinical presentation and radiological features of a rare case of primary non-Hodgkin’s lymphoma of the superficial branch of the radial nerve. Following gross-total resection, the patient received adjuvant chemotherapy and was free of disease at the last follow-up.

LESSONS

With astute observation, less common and sinister peripheral nerve lesions can be recognized at an early stage and tend to be associated with a relatively short history of peripheral sensorimotor deficits and subtle radiographic changes. In such a setting, consideration should be given to performing a biopsy rather than gross-total resection, indeed sparing the parent nerve and facilitating diagnosis. Definitive treatment for PLPN is chemotherapy with the addition of radiotherapy in some circumstances.
Hemifacial spasm associated with posterior inferior cerebellar artery aneurysm: illustrative case
Authors: Inoue Gaku , Endo Hidenori , Kanoke Atsushi , Kawaguchi Tomohiro , Tominaga Teiji
Published: April 2023

BACKGROUND

Hemifacial spasms (HFSs) complicated by intracranial aneurysms are rare. Recently, endovascular treatment has been widely used for this disease entity and can allow the cessation of intracranial aneurysm arterial pulsation, leading to recovery from the HFS. Here, the authors present a case of HFS associated with an ipsilateral posterior inferior cerebellar artery (PICA) aneurysm successfully treated with open surgery.

OBSERVATIONS

A 68-year-old woman was annually followed-up for an incidentally found right PICA aneurysm. Over 3 years, the PICA aneurysm gradually increased in size, which eventually led to right HFS. An axial fast spoiled gradient-recalled echo sequence with gadolinium enhancement showed the PICA aneurysm compressing the root exit zone (REZ), which was attributed as the cause of the HFS. However, a fusion image of the three-dimensional T1-weighted fast spin-echo sequence and magnetic resonance angiogram clearly showed a direct contact between the REZ and the anterior inferior cerebellar artery (AICA), which was located at the apex of the PICA aneurysm. Intraoperatively, the AICA was found compressing the REZ; hence, microvascular decompression with aneurysmal clipping was performed. The HFS resolved immediately after surgery.

LESSONS

In cases of HFS associated with an ipsilateral intracranial aneurysm, a detailed neuroradiological assessment to identify the responsible lesion is important to use the most optimal treatment of choice.
Adjuvant multimodal treatment for spinal intradural extramedullary capillary hemangioma with subpial growth: illustrative case
Authors: Matsumoto Hiroaki , Shimokawa Nobuyuki , Sato Hidetoshi , Takami Toshihiro
Published: April 2023

BACKGROUND

Spinal intradural extramedullary capillary hemangiomas are rare vascular lesions. Although total resection is the first treatment, the efficacy of adjuvant therapies, such as steroid or radiation therapy, has not been investigated.

OBSERVATIONS

A 74-year-old man presented with progressive back pain, gait disturbance, and left chest pain. Spinal magnetic resonance imaging (MRI) revealed an intradural extramedullary lesion at the middle thoracic level. Preoperatively, systemic steroid administration improved his chest pain and reduced the tumor size. The authors performed tumor extirpation. Because the tumor strongly adhered to the pia matter, in short, the tumor accompanied with partial subpial growth, subtotal resection was performed, leaving a thin layer of the tumor. A pathological examination revealed capillary hemangioma. His gait disturbance showed rapid improvement. Stereotactic cyber knife treatment was performed for the residual tumor at 1 month after the operation. Serial MRI showed a gradual decrease in the tumor size and no recurrence at 2 years after the operation.

LESSONS

When a tumor adheres to the spinal cord or nerve root, immoderate total resection should not be performed to avoid exacerbating the clinical symptoms. Adjuvant therapies, such as a systemic steroid administration or radiation therapy, may provide satisfactory control of spinal capillary hemangiomas.

The Innovation Structuring of street vendors In Maros regency (supervised by Deddy T. Tikson and Hasniati). This study aims to analyze the results of innovation structuring of street vendors in Maros Regency based on the criteria of the United Nations (UN). This research was conducted in Culinary Area of ​​No Wave Beach of Maros Regency. The method used in this study is a qualitative approach with a focus on innovation results from the arrangement of street vendors in Maros regency. There is also a research design used is case study (case study). The result of the research shows that the innovation of street vendors in Maros Regency based on criterion of United Nations (UN) is less successful. This was because of the 6 indicators, 1 indicator that partnership is not met because there was no professional cooperation either government, private or banking. 4 less effective indicators that sustainability was not working well because there was no special regulation governing culinary areas, innovation indicators in local and transferable contexts did not provide specific publications related to secondary data as well as special information related to street vendors in the area of ​​culinary beaches and non- other areas were still difficult to adopt the concept in applied. Indicators of gender equality and social exclusion because they had not demonstrated traditional special food and local wisdom in the arrangement of street hawkers, although gender and local wisdom were not contradictory and indicators of leadership and community empowerment due to governor commitment were not accompanied by clear policies and lack of merchant empowerment concepts a clear five foot post relocation. The indicators that become the strength of this innovation was the impact. Impact indicators provide benefits for both street vendors, government and the environment.

This paper aims to show how the formation of political preferences of first-time voters occurs. As a factor that influences political behavior, the understanding of political preferences becomes important thinking of a person or community, including the first-time voters. As one of the important segments in political dynamics, first-time voter existence is always an interesting aspect to be examined, including their existence as people who are about to exercise their voting rights for the first time. So far, the first-time voters have tended to be seen as a segment that seems simply to understand their political behavior tendencies due to assumed it is often reflecting the political attitudes of their parents or family. However, since the emergence of social media, there has been a tendency of shifted related to their forming political preferences. Based on research conducted in the City of Makassar towards students in several high schools as first-time voters, this paper aims to show how the actual role of schools, parents, and social media roles in shaping their political preferences that shaping the tendency of their political behavior.

Circulating platelets are sometimes exposed to high shear rate environments due to vascular stenosis, and the effect of transiently elevated pathological high shear rates on platelet activation and aggregation function has not been clarified. The aim of this study was to investigate the effect of pathological high shear rate (8302s-1) exposure time (3.16-25.3 ms) on platelet activation and aggregation function. In addition, by adding active ingredients of antiplatelet drugs such as ASA (an active ingredient of aspirin), Ticagrelor, Tirofiban and GP1BA (platelet membrane protein GPIb inhibitor) in vitro, we studied TXA2, P2Y12-ADP, GPIIb/IIIa-fibrinogen and GPIb /IX/V-vWF receptor pathways to determine platelet activation function mediated by pathological high shear rate. In this study, we designed a set of microfluidic chips with stenosis lengths of 0.5 mm, 1 mm, 2 mm, 3 mm, and 4 mm, all with 80% stenosis, to generate pathological high shear forces that can act at different times. The whole blood flowing through the microchannels was collected by perfusion of sodium citrate anticoagulated whole blood at a physiological arterial shear rate (1500 s-1), and the expression levels of platelet surface activation markers (P-selectin and GP IIb/IIIa) and the degree of platelet aggregation were analyzed by flow cytometry; platelet aggregation patterns were observed by microscopic examination of blood smears. The results showed that shearing significantly increased platelet activation and aggregation levels compared to un-sheared whole blood, and the activation and aggregation levels increased with increasing duration of pathological high shear rate. In vitro inhibition studies showed that ASA barely inhibited the expression of P-selectin and PAC-1 on the platelet surface; Ticagrelor effectively inhibited the expression of both P-selectin and PAC-1; Tirofiban significantly inhibited the expression of PAC-1 on the platelet surface and slightly inhibited the expression of P-selectin; GP1BA significantly inhibited the expression of both. Our results suggest that transient pathological high shear rate (8302s-1) exposure can induce platelet activation in a time-dependent manner; however, the mechanism is more complex and may be due to the following reasons: transient elevated pathological high shear rate activates platelets through the GPIb/IX/V-vWF receptor pathway, and after platelet activation, its surface membrane protein GPIIb/IIIa receptors activate platelets through fibrinogen to form platelet-platelet aggregates, and further activation of active substances such as ADP and TXA2 released by platelet alpha particles, which contribute to the formation of irreversible platelet aggregation.

Published: April 2023

Background:

A potential role of the antimicrobial peptide LL-37, which is upregulated after infection, in the pathogenesis of Alzheimer’s disease (AD) was identified. However, the clinical relevance of LL-37 in AD is not clear yet.

Objective:

This study aims to investigate the association of circulating LL-37 with longitudinal cognitive decline and neurodegeneration among older adults with memory complaints.

Methods:

This cohort study recruited 357 older adults with memory complaints. Participants were followed-up for two years and the cognitive functions were assessed using the Mini-Mental State Examination (MMSE). Serum LL-37, pTau181, and tTau levels were determined at baseline. Associations of baseline LL-37 with longitudinal cognitive decline and change of neurodegenerative biomarkers were analyzed.

Results:

No difference was found in the slope of longitudinal cognitive decline during follow-up between the low and high LL-37 group, adjusting for age, sex, education, body mass index, APOE ɛ4 carrier status, comorbidities, and baseline MMSE scores (difference in slope: 0.226, 95% CI: –0.169 to 0.621). Higher LL-37 levels were associated with longitudinal cognitive decline, as indicated by a decrease of MMSE scores of 3 points or above during follow-up (OR = 2.11, 95% CI: 1.32 to 3.38). The high LL-37 group had larger slopes of the increase in neurofilament light (difference in slope: 3.759, 95% CI: 2.367 to 5.152) and pTau181 (difference in slope: 0.325, 95% CI: 0.151 to 0.499) than the low LL-37 group.

Conclusion:

These findings support an association of the antimicrobial peptide LL-37 with AD from a clinical perspective.
Proposal for a Biologic Staging System of Parkinson’s Disease

Published: April 2023

The Parkinson’s disease (PD) research field has seen the advent of several promising biomarkers and a deeper understanding of the clinical features of the disease from the earliest stages of pathology to manifest disease. Despite progress, a biologically based PD staging system does not exist. Such staging would be a useful framework within which to model the disease, develop and validate biomarkers, guide therapeutic development, and inform clinical trials design. We propose that the presence of aggregated neuronal α-synuclein, dopaminergic neuron dysfunction/degeneration, and clinical signs and symptoms identifies a group of individuals that have Lewy body pathology, which in early stages manifests with what is now referred to as prodromal non-motor features and later stages with the manifestations of PD and related Lewy body diseases as defined by clinical diagnostic criteria. Based on the state of the field, we herein propose a definition and staging of PD based on biology. We present the biologic basis for such a staging system and review key assumptions and evidence that support the proposed approach. We identify gaps in knowledge and delineate crucial research priorities that will inform the ultimate integrated biologic staging system for PD.
