Published: April 2023

Background. Lumbar spinal stenosis is a pathological constriction of the central spinal canal, lateral pocket or intervertebral foramen. The complication rate of lumbar spinal stenosis surgery ranges from 10 to 24 %. In order to reduce the number of intraoperative and early postoperative complications accompanied by the development of neurological deficit, various techniques of intraoperative neurophysiological monitoring are used.Aim. Study of informativity of the use of intraoperative neurophysiological monitoring during surgical treatment of degenerative lumbar spinal stenosis based on the experience of the neurosurgical department of the Republican Clinical Hospital (Yoshkar‑Ola, Mari El Republic).Materials and methods. Thus, 69 decompressive‑stabilizing surgical interventions for degenerative lumbar spinal stenosis at the L3–L5 level, performed with intraoperative neurophysiological monitoring (free‑run electromyography, transcranial motor evoked potentials, somatosensory evoked potentials, triggered electromyography were included in the retrospective study).Results. During intraoperative neurophysiological monitoring transcranial motor evoked potentials from the legs was registered in all cases. Normal somatosensory evoked potentials were recorded in most cases, in 12 cases (17.4 %) baseline somatosensory evoked potentials were not registered due to preoperative neurological deficits and the presence of concomitant somatic pathology. 308 inserted pedicular screws were examined using the triggered electromyography. Muscle responses were registered in 31 (45 %) operations, 45 (14 %) screws. True negatives were registered with 29 (64.4 %), true positives were registered with 12 (26.7 %), and false positives were registered with 4 (8.9 %) screws. In the postoperative period no increase in motor and sensory neurological deficits was observed in all patients; no neurological signs of screw malpositioning were revealed.Conclusion. The use of multimodal intraoperative neurophysiological monitoring during surgical treatment of lumbar spinal stenosis reduces the risk of postoperative neurological complications.

Introduction. Injuries to the brachial plexus are one of the most severe types of injuries to the nerves of the upper limb, and variants with the separation of the roots from the spinal cord represent a very difficult category of injuries to treat. Among patients who have received such injuries, there is a very high incidence of disability, since it is possible to achieve only partial restoration of the function of the upper limb. Recently, the method of transposition of functioning muscles has been growing in popularity due to its reliability and relatively short recovery time of function.The purpose of the work is to analyze the literature data on the possibility of using the method of transposition of functioning muscles in the complex treatment of victims with brachial plexus injuries.The authors have searched PubMed and RSCI databases over the past 25 years for keywords: peripheral nerve damage, tendon transposition, transposition of functioning muscles, nerve injury, brachial plexus injury, spinal cord root avulsion. In the selected 23 most relevant papers, the muscles used for transposition, indications and timing of operations, results and complications were analyzed, compared with other methods of surgical treatment of brachial plexus injuries. The analysis of studies has shown that the transposition of functioning muscles allows in most cases to restore the target movement to the useful level of M3–M4 on the MRC scale, is a more reliable method and allows achieving better results, especially in patients with severe complete injuries of the brachial plexus. An important disadvantage of free hip thin muscle transplantation operations is the risk of microanastomosis thrombosis, which requires detailed preoperative planning and good microsurgical technique of the operating team.Conclusion. Free transplantation of 2 functioning muscles is currently the method of choice for restoring upper limb movements in patients with complete brachial plexus injuries.

Authors: Архипова И.В. 
Published: April 2023

Целью настоящего исследования является выявление прототипического способа межкатегориального взаимодействия таксиса с функционально-семантическими категориями и субкатегориями аспектуальности, темпоральности, временной локализованности, итеративности и фазовости. При пересечении таксиса и сопряженных с ним категорий и субкатегорий, «ответственных» за репрезентацию временных отношений, реализуется механизм межкатегориального кроссинга как прототипический способ межкатегориального взаимодействия. Он детерминирует актуализацию различных примарно-таксисных категориальных ситуаций одновременности и разновременности в немецких высказываниях с девербативами и темпоральными предлогами.
The purpose of this paper is to identify a prototypical way of intercategorial interaction of taxis with functional-semantic categories and subcategories of aspectuality, temporality, temporal localization, iterativeness and phaseness. At the intersection of taxis and related categories and subcategories, “responsible” for the representation of temporal relations, the mechanism of intercategorical crossing is realized as a prototypical way of intercategorial interaction. It determines the actualization of various primary taxis categorical situations of simultaneity and non-simultaneity in German statements with deverbatives and temporal prepositions.

: HIV patients frequently have mucocutaneous manifestations, which could be the first sign of the infection and can also be prognostic markers for disease progression. This study was done to note the different mucocutaneous manifestations occurring in the people living with HIV/AIDS.: One hundred ensuent HIV seropositive patients who attended the opd were included in the study.: The bulk of the study participants were illiterate, had a mean age of 32, and a male to female ratio of 2:1. The patients' number of manifestations ranged from 01 to 05. The most typical illnesses observed in this investigation were dermatophyte infections followed by oral candidiasis. The most frequent non-infectious symptoms observed in this investigation were SD and PPE. The most prevalent STI was herpes genitalis. Inversely correlated with CD4 level were the type, number, and severity of mucocutaneous symptoms. The number of manifestations and CD4 count were found to be inversely correlated. The majority of PLHAs (55%) exhibited several manifestations. The majority of the manifestations are unusual, persistent, recurrent, and resistant to the therapy. Young patients presenting with extensive SD, PPE, OC, scrofuloderma, and HZ should encourage the clinician to investigate the patient's sero-reactivity status
Beliefs and Practices of Academic Reading and Writing in Researchers in Training
Authors: Franco Jésica 
Published: April 2023

This study aimed to examine and explain teachers' and students' reading and writing practices and beliefs in a master's program at a public university in Mexico. We conducted qualitative cross-sectional research. A self-administered questionnaire with open-ended questions was used in the initial stage to examine two distinct beliefs of reading and writing and identify key actors. Six interviews with teachers and students were carried out during the second stage. The study corroborates that the different beliefs are not mutually exclusive but can simultaneously exist in the same person, though they may be weighted differently. Those who firmly hold transmissive beliefs understand that reading and writing are processes to obtain (decode) and transmit (encode) information. In practice, these people emphasize the importance of identifying main ideas, summarizing texts, writing following a structure and taking up ideas from other authors. On the contrary, those who mostly hold transactional beliefs think that reading and writing are creative, dialogic and meaning-construction processes. Some of their reading and writing practices focus on aspects such as: defining a standpoint regarding the text, investigating the context of the author or reader, and defining reading or writing purposes. The research highlights the possibility of reconceptualizing reading and writing in the academic context, valuing their epistemic function and transforming the prevalent discourse that conceives them as technical and universal skills, which can be improved by correctly applying grammatical rules or following effective formulas.

IntroductionProstate cancer is the second leading cause of cancer deaths among men in the United States and harms Black men disproportionately. Most US men are uninformed about many key facts important to make an informed decision about prostate cancer. Most experts agree that it is important for men to learn about these problems as early as possible in their lifetime.ObjectivesTo compare the effect of a community health worker (CHW)-led educational session with a physician-led educational session that counsels Black men about the risks and benefits of prostate-specific antigen (PSA) screening.MethodsOne hundred eighteen Black men recruited in 8 community-based settings attended a prostate cancer screening education session led by either a CHW or a physician. Participants completed surveys before and after the session to assess knowledge, decisional conflict, and perceptions about the intervention. Both arms used a decision aid that explains the benefits, risks, and controversies of PSA screening and decision coaching.ResultsThere was no significant difference in decisional conflict change by group: 24.31 physician led versus 30.64 CHW led (P=.31). The CHW-led group showed significantly greater improvement on knowledge after intervention, change (SD): 2.6 (2.81) versus 5.1 (3.19), P&lt;.001). However, those in the physician-led group were more likely to agree that the speaker knew a lot about PSA testing (P&lt;.001) and were more likely to trust the speaker (P&lt;.001).ConclusionsCHW-led interventions can effectively assist Black men with complex health decision-making in community-based settings. This approach may improve prostate cancer knowledge and equally minimize decisional conflict compared with a physician-led intervention.

Published: April 2023

Objectives: Destructive spondyloarthropathy (dSpA) occurs due to inflammatory destruction of axial joints due to beta2-microglobulin (beta2-M) accumulation in patients with end-stage renal disease (ESRD) receiving renal replacement therapy (RRT). This study aimed to investigate the frequency of dSpA in ESRD patients receiving RRT, by the diagnostic criteria sets of inflammatory back pain (IBP) and inflammatory classical SpA.
Methods: A total of 140 patients were included. The data of the demographic informations, laboratory tests, clinical findings, HLA allele subgroups were collected. Sacroiliac and lateral feet X-rays and if necessary sacroiliac tomography were taken in patients with dSpA related pain. dSpA was investigated according to the Amor and ESSG criteria sets.
Results: Fifty two patients were women (37%). The mean age was 51 ± 15 years. IBP and sacroiliitis were detected in 22 and 28 of the patients, respectively. There was a significant difference according to sacroiliitis and IBP in terms of CRP (p=0.028, p=0.043). dSpA were detected in 21 (15%) patients. Presence of HLA-A1 and duration of HD were determined as independent risk factors for dSpA.
Conclusions: In the diagnosis of dSpA, the character and inflammatory origin of the pain and inflammatory markers should be investigated in addition to the radiological criteria.

Published: April 2023

The excessive use of synthetic insecticides in modern agriculture has led to the contamination of the environment and the development of insect resistance. In this study, we evaluated the potential of tangerine (Citrus reticulata L.) peel essential oil (EO) as a natural insecticide against greenhouse whitefly (Trialeurodes vaporariorum W. (Homoptera: Aleyrodidae)), a common pest in greenhouse production. Petroleum ether (PET) and n-hexane (HEX) were used as solvents to extract essential oil (EO) from tangerine peels. The yield of EO was 1.59 % and 2.00 % (m/m) for PET and HEX, respectively. The insecticidal activity of EO was evaluated by measuring the mortality rate (MR) of greenhouse whiteflies at different time intervals. The results showed that PET and HEX extracts of tangerine EO effectively controlled the greenhouse whitefly. With both solvents, it was observed that with doses of 12.5% (v/v), similar results were achieved as with the positive control (corresponding to the commercial insecticide imidacloprid). Additionally, the FTIR analysis found that the EO contained d-limonene, which may be the source of its insecticidal properties. Therefore, tangerine peel essential oil is an excellent natural insecticide candidate for controlling greenhouse whiteflies effectively and sustainably.

Published: April 2023

Abstract
The global environment has been changing rapidly since the 21st century, and the harmonious coexistence between human beings and nature has been seriously challenged, and the green transformation of highly polluting enterprises has become a requirement of the times. Based on monthly corporate bond data and annual corporate financial data from January 2009 to December 2019 in China, this paper constructs a triple difference model to test the impact of carbon trading system on corporate bond credit spreads. The results show that, first, the carbon trading system has a reducing effect on the credit spreads of bonds of highly polluting companies in the carbon trading pilot region, and the implementation of the carbon trading system can promote bond financing in the green transformation process of highly polluting companies. Second, there is heterogeneity in the impact of the carbon trading system on the credit spreads of bonds of high-polluting firms, with private firms, small-scale firms and emerging firms having a greater reduction in corporate bond credit spreads than state-owned firms, large-scale firms and senior firms. Third, the carbon trading system exposes high-polluting firms to the risk of bankruptcy in the "carbon trading market" due to high operating costs and small net profits, thus incentivizing high-polluting firms to raise bonds in the "investment and financing market" to promote their green transformation.
Exploring the socioeconomic status, challenges, and roles of waste pickers in Arusha city's solid waste management system: An insight into their contributions in Tanzania's cities
Authors: Onesmo Clashon 
Published: April 2023

Abstract

Waste pickers play essential socioeconomic and environmental scenes in cities of developing countries. This study explored waste pickers to understand their socioeconomic characteristics, challenges, and roles in Tanzania cities. A mixed-methods research design was utilized, including questionnaires, interviews, and observations, to gather data from waste pickers in the city. The findings revealed that Arusha generates 550 tons of waste per day, with male waste pickers dominating the industry at 60%. Many waste pickers were within the active working age of 18-49 (90%), and two third possessed primary education (66%). Many waste pickers were single (50%) and married (42.5%). A significant portion of them (69%) were native to the region, while less than a third had migrated. On average, waste pickers in Arusha earn up to 153,000 TZS (USD 66) monthly, hence looking for an alternative job. Waste pickers also play a significant role in the city's informal economy. They act as recovery hubs and central suppliers of recycling materials. Their work helps extend the lifespan of landfills, conserve resources, and protect the environment. However, they face challenges such as low earnings, scarcity of materials, and health issues such as injuries, harassment, and low prices for materials. Formalizing and integrating waste pickers into the city's solid waste management system can reduce GHG emissions, providing a sustainable and meaningful model for managing waste and mitigating climate change in Arusha. The study underscores the importance of acknowledging and supporting the role of waste pickers in achieving sustainable waste management and a climate-smart city.
A high-resolution time-frequency analysis tool for fault diagnosis of rotating machinery
Authors: Cui Zhenghao , Yu Gang 
Published: April 2023

Abstract
Fault features in a mechanical system typically appear as transient impulses which can be analyzed using time-frequency analysis (TFA) methods. Recently, a new TFA technique termed as time-reassigned multisynchrosqueezing transform (TMSST) was proposed to capture the transient impulses in a signal for fault diagnosis. However, the TMSST was developed based on the short-time Fourier transform (STFT) which could yield unclear high-frequency image due to the fixed sliding time window used in STFT. To overcome this limitation, TMSST is combined with the S-transform and local maximum method in this study for an improved time frequency representation in the signal analysis. An extractive reconstruction algorithm binding the maximum value of the spectral envelope is further proposed for spectral decomposition. A simulated noise-added signal and four experimental bearing defect data are used in the study to verify the validity and effectiveness of the technique developed in a step-by-step manner. The results confirm that the proposed technique can accurately extract the fault features for bearing operated under constant or varying speed conditions.

Abstract

The objective of this work was to optimize the interesterification temperature (X1), time (X2) and catalyst concentration (X3) ofAllanblackia, African walnut and fluted pumpkin seed oil blend for bakery shortening production, using a rotatable central composite design (RCCD) in response surface methodology (RSM). The extracted seed oils were interesterified using sodium methoxide as catalyst. Solid fat content, smoke point, melting point, density, viscosity, Iodine value and free fatty acid were evaluated as responses. Regression models were generated and adequacy tested with lack of fit test and coefficient of determination (R2). The results showed that interesterification temperature, interesterification time and catalyst concentration of the oil blend had significant (p˂ 0.05) effects on responses, with R2value of 96.8, 95.3, 94.2, 90.1, 99.5, 93.2 and 75.7 % and C.V of 0.266, 0.146, 0.502, 0.499, 0.602, 0.448 and 7.830 %, respectively for solid fat content, smoke point, melting point, density, viscosity, Iodine value and free fatty acid. Model lack-of-fit in all cases were desirably not significant (p>0.05). Adequate precision values were 16.2006, 13.328, 11.758, 10.054, 46.69, 10.024 and 14.182 for solid fat content, smoke point, melting point, density, viscosity, Iodine value and free fatty acid. Predicted optimum condition and desirability index of 0.907 was obtained at 74.57°C, 46.0 min and 0.278 % interesterification temperature, time and catalyst concentration respectively, while optimum solid fat content, smoke point, melting point, density, viscosity, Iodine value and free fatty acid were 5.15 %, 221.91°C, 32.49°C, 0.911, 25.06 cSt, 76.42 g/100g and 0.08 % respectively. The experimental results obtained validate the predicted model within the acceptable range of the responses. The results also suggest that the obtained model is acceptable and recommended for the optimization of interesterification temperature, time and catalyst concentration for improved bakery fat quality and consistency. Melting point and FFA of the oil blend were reduced significantly (p<0.05) after interesterification, while smoke point and Iodine value increased significantly (p<0.05).
