Communication as the crucial link: Toward a multilevel approach to normative social influence
Authors: Geber Sarah , Sedlander Erica
Published: January 2022

Social norms are informal rules within a group or society. Despite the consensus that social norms affect behavior, there is an inherent tension in the cross-disciplinary norms literature between the conceptualization of norms as individual and collective phenomena. The present paper capitalizes on the potential of communication as the link between different levels of social norms to develop an integrative approach to normative social influences. Concretely, it refers to the differentiation between perceived and collective norms, systematizes the current literature on the role of communication in social normative influences, and outlines how communication serves as functional link between the individual and collective level of norms. The resulting multilevel approach to normative social influences (MANSI) allows us to reflect on norms as dynamic phenomena that account for individual and social change. Ultimately, we discuss challenges and areas for further inquiry for the study of norms, and thereby derive recommendations for future research on multilevel normative social influences.

Published: January 2022

Pheochromocytomas with vena cava thrombus are extremely rare, with only a few cases reported in the literature. Radical nephrectomy with adrenalectomy and inferior vena cava (IVC) thrombectomy is the treatment of choice. However, it is a challenging procedure and its surgical approach is yet to be standardized. We present a case of a 49-year-old male incidentally diagnosed with a pheochromocytoma with aggressive local invasion and a level 1 vena cava thrombus. A laparoscopic right radical nephrectomy with right adrenalectomy, IVC thrombectomy and cavorraphy. A detailed revision of the technique is performed and compared with current strategies for pheochromocytoma optimal treatment. Renal and adrenal masses with vena cava thrombus are associated with high morbidity and mortality, particularly in the case of pheochromocytoma. The management is complex but minimally invasive surgery can be performed safely in the context of an experienced multidisciplinary team.

Authors: Sergeeva Ekaterina Yu. , Khorzhevskii Vladimir A. , Ruksha Tatiana G.
Published: January 2022

Pagetoid reticulosis (PR) is a rare type of mycosis fungoides. Clinical symptoms of PR can mimic other skin diseases of papulosquamous, neoplastic, and infectious origin that hampers PR diagnostics. The main histopathologic feature of PR is dense intraepidermal infiltration by medium to large-size lymphocytes through the epidermis leading to pagetoid plaque formation. There are three common immunophenotypes of PR: CD4-positive T-helper phenotype (CD3+, CD4+, CD8); T-cytotoxic/suppressor (CD3+, CD4, CD8+); and double negative phenotype (CD3+, CD4, CD8). The clinical case of PR with rare immunophenotype (CD2+, CD3+, CD8+ lymphoid infiltrate) is presented. The careful analysis of the symptoms, pathomorphological and immunohistochemical data is necessary for accurate PR diagnostics.

Background. There is a need to assess the diagnostic significance of the symptoms of nail damage, as well as available effective methods for diagnosing psoriatic arthritis in the early stages.
Aims. To study of the occurrence of symptoms of psoriatic onychodystrophy in patients with psoriatic arthritis and assessment of the diagnostic significance of the ultrasound method for diagnosing enthesitis as an early symptom of psoriatic arthritis among patients with onychodystrophy and without psoriatic arthritis in case history.
Methods. It was a prospective clinical study based on the Clinic of Skin and Venereal Diseases of the Military Medical Academy. We made the clinical assessment of symptoms of onychodystrophy among patients with and without psoriatic arthritis and the evaluation of the diagnostic significance of the ultrasound method for diagnosing psoriatic arthritis under the control of magnetic resonance imaging of the joints.
Results. 45 patients with psoriatic arthritis and 134 patients with psoriasis without arthritis were examined. Psoriatic onychodystrophy was significantly more common in the group of patients with psoriatic arthritis (p = 0.028). The most characteristic symptoms of onychodystrophy in patients with psoriatic arthritis are oil spots and symptom combinations: oil spots and subungual hyperkeratosis, onycholysis and subungual hyperkeratosis, pits and longitudinal ridges, oil spots and longitudinal ridges. The ultrasound method for the diagnosis of psoriatic arthritis has shown its high diagnostic significance (Se = 81.8%, Sp = 88.0%). The most characteristic symptoms of arthritis on ultrasound examination are hypoechoic structures of the Achilles tendons and the presence of fluid in the peri- and retro-Achilles bursa.
Conclusions. The symptom of oil spots and combinations of oil spots with subungual hyperkeratosis, onycholysis with subungual hyperkeratosis, pits with longitudinal ridges and oil spots with longitudinal ridges can be considered diagnostically significant in the examination of early psoriatic arthritis, and the ultrasound method is highly effective in diagnosing early manifestations of arthritis.

Authors: Nikolaeva Marina Yu. , Monakhov Konstantin N. , Sokolovskiy Evgeny V.
Published: January 2022

The notion of skin microbiome encompasses a heterogeneous group of microorganisms that belong to various taxonomic units, such as bacteria, archaea, viruses, and fungi. The impact of these microbial community constituents upon the epidermal barrier condition, and upon the immune system functioning, is being intensely scrutinized. There is a particular interest in studying the role that the microorganisms of genus Staphylococcus spp. play in the course of physiological and pathological processes occurring in the skin. This review examines in detail the interaction of the microorganisms of genus Staphylococcus spp. with the microbial community constituents, as well as with the skin immune system in normal condition and in the condition associated with inflammatory dermatoses. There are also the data given on S. aureus pathogenicity factors, the data on the impact of this microorganism upon the course of atopic dermatitis, and upon the course of psoriasis. The review examines the role that coagulase-negative staphylococci, S. epidermidis in particular, play in maintaining the microbiome homeostasis. The review as well examines the impact of the skin microbiome upon the development and activity of the skin immune system, and upon maintaining the integrity of the epidermal barrier.

Published: January 2022

The development of both malignant neoplasms mycosis fungoides and cutaneous malignant melanoma is a rare condition; nevertheless, the literature describes both cases of the development of mycosis fungoides in patients with a primary diagnosis of melanoma and the detection of cutaneous malignant melanoma in patients with T-cell lymphomas of the skin. The question of the effect of previous therapy for mycosis fungoides on the risk of cutaneous malignant melanoma remains controversial. Currently, the world community is considering a possible pathogenetic relationship between these two oncopathologies. The clinical observations of the development of cutaneous malignant melanoma in 2 patients with mycosis fungoides presented in the article emphasize the importance of a thorough clinical and dermatoscopic examination of all pigmented formations for the timely detection of malignant melanocytic neoplasms, the presence of which radically affects the further choice of treatment tactics for patients.
Non-surgical treatments for basal cell skin cancer
Authors: Kubanov Alexey A. , Saytburkhanov Rifat  R. , Plakhova Xenia I. , Kondrakhina Irina N.
Published: January 2022

Basal cell carcinoma is the most common nonmelanoma skin cancer. It originates from undifferentiated cells in the basal cell layer of the epidermis or from the outer root sheath of the hair follicle. The most important factor in development of basalioma is ultraviolet radiation. Surgery is considered the gold standard of treatment for basal cell cancer. However, nonsurgical options are available for individuals who are unsuitable for surgery. The purpose of this review is to summarize the efficacy and indications of alternative, nonsurgical treatments that can be used in the management of basal cell cancer
Effective nonsurgical treatments include destructive methods (eg, curettage and electrodessication, cryosurgery, laser), photodynamic therapy, topical medications, hedgehog pathway inhibitors. Nonsurgical therapeutic alternatives are safe and effective for the treatment of BCC. Factors such as tumor location, size, and histopathological subtype should be taken into consideration when selecting optimal treatment, cosmetic results and patient preference should be considered too.
To search for the necessary literature, the PubMed, MedLine, Web of Science and RSCI databases were used.
Clinical manifestations, classification, and surgical management of sacral tumors and the need for personalized approach to sacrectomy
Authors: Fiani Brian , Runnels Juliana , Rose Alexander , Kondilis Athanasios , Wong Amelia , Musch Brian L.
Published: January 2022

Background:

Although comprising 7% of all spinal tumors, sacral tumors present with a litany of issues due to their slow growth and difficulty in detection. As a result, sacral tumors can grow unperturbed for years until a patient presents for an incidental workup of an unassociated minor trauma or an offending primary tumor source that has metastasized to the sacrum; in most cases, this includes primary tumors of the breast, prostate, and lung. The goal of this review is to outline the pathophysiology underlying sacral tumors including the various tissues and structures that can be targeted for treatment, along with a discussion of the surgical approach to sacrectomy.

Methods:

An extensive review of the published literature was conducted through PubMed database with articles simultaneously containing both search terms “sacral tumors” and “sacrectomy.” No date restrictions were used.

Results:

The search yielded 245 related articles. Cross-checking of articles was conducted to exclude of duplicate articles. The articles were screened for their full text and English language availability. We finalized those articles pertaining to the topic.

Conclusion:

Once a sacral tumor has reached the point of diagnostic detection, invasive sacrectomy is typically utilized (through an anterior, posterior, or combination approach) to locally isolate and resect the tumor and minimize risk of future tumor growth and additional bone loss. While institutions have varying criteria for surgical approaches, a combination of anterior and posterior approach has traditionally been used in total and high sacrectomies due to the control it provides surgeons toward the rectum and vasculature anterior to the sacrum. A posterior-only approach can be performed for tumors that failed to invade pelvic organs or extend past the lumbosacral junction. Early detection with screenings can help avoid invasive sacrectomy by identifying the onset of tumor formation in the sacrum, particularly for highly metastatic cancers.
Decompressive craniotomy for malignant middle cerebral artery infarction: The quest for an African perspective
Authors: Naidoo Dinesh
Published: January 2022

Background:

Although associated with controversy, decompressive craniotomy (DC) for malignant middle cerebral artery infarction (MMCAI) is an unequivocally lifesaving intervention. DC for MMCAI is rarely performed in lower- to middle-income countries.

Methods:

A systemic review was performed in attempt to determine the rates of utilization and outcomes of DC on the African continent.

Results:

Only two African studies describing DC for MMCAI were found.

Conclusion:

DC for MMCAI is rarely performed and/or reported on the African continent. The African perspective for this needs to be urgently broadened.
Perspective: Early diagnosis and treatment of postoperative recurrent cerebrospinal fluid fistulas/ dural tears to avoid adhesive arachnoiditis
Authors: Epstein Nancy E.
Published: January 2022

Background:

Intraoperative traumatic cerebrospinal fluid (CSF) fistulas/dural tears (DT) occur in up to 8.7–9.5% of primary lumbar surgical procedures. Further, they recur secondarily in between 8.1% and 17% of cases. It is critical to diagnose and treat these recurrent lumbar DT early (i.e. within 3–4 weeks of the index surgery) to avoid the evolution of adhesive arachnoiditis (AA), and its’ permanent neurological sequelae.

Methods:

Postoperative lumbar CSF fistulas/DT should be diagnosed on postoperative MR scans, and confirmed on Myelo-CT studies if needed. They should be definitively treated/occluded early on (e.g. within 3–4 postoperative weeks) to avoid the evolution of AA which can be readily diagnosed on MR studies, and corroborated, if warranted, on Myelo-CT examinations. The most prominent MR/Myelo-CT findings include; nerve roots aggregated in the central thecal sac, nerve roots peripherally scarred/adherent to the surrrounding meningeal wall (“empty thecal sac sign”), soft tissue masses in the subarachnoid space, and/or multiple loculated/scarred compartments.

Results:

Percutaneous interventional procedures (i.e. epidural blood patches, injection of fibrin glue (FG)/fibrin sealants (FS)) are rarely effective for treating postoperative recurrent lumbar CSF fistulas. Rather, direct surgical occlusion is frequently warranted including the use of; an operating microscope, adequate surgical exposure, 7-0 Gore-Tex sutures, muscle/dural patch grafts or suture anchors, followed by the application of microfibrillar collagen, and fibrin sealant/glue.

Conclusion:

Lumbar AA most commonly results from the early failure to diagnose and treat recurrent postoperative CSF fistulas. Since the clinical course of lumbar AA is typically one of progressive neurological deterioration, avoiding its’ initial onset is key.
Neoplastic cerebral aneurysm from triple-negative breast cancer: A case report
Authors: Nussbaum Eric S. , Torok Collin M. , Khalil Zena M. , Pederson John M.
Published: January 2022

Background:

We present a rare case of a ruptured neoplastic aneurysms (NCA) caused by metastatic spread of triple-negative breast cancer (TNBC) in a female patient in her 60s. The patient had a medical history of TNBC and presented to the emergency department after experiencing 3 days of persistent headache.

Case Description:

Head computed tomography (CT) revealed a small volume subarachnoid hemorrhage and digital subtraction angiography revealed a 3.9 x 3.5 x 4.2 mm aneurysm or pseudoaneurysm involving the left middle cerebral artery. The aneurysm was successfully clipped and resected, and histopathological examination confirmed triple-negative invasive ductal breast carcinoma within the aneurysm. Six weeks after surgery, she underwent stereotactic radiosurgery and began treatment with chemotherapy. Four months later, the patient presented once again with acute severe headache, and magnetic resonance imaging revealed multiple small lesions within the brain parenchyma, compatible with new metastatic deposits. The patient was subsequently treated with whole-brain radiation therapy and chemotherapy. Over the ensuing 4 months, CT revealed progression of malignancy in the chest, abdomen, and pelvis. Chemotherapy and radiation therapy were terminated, and the patient unfortunately succumbed to her disease 6 months later.

Conclusion:

In patients with NCA with poor prognosis due to aggressive brain metastases, treatments that improve quality of life and survival time should be favored.

Authors: Mallakian Shohreh , Rezanezhad Roghayeh , Jalali Mahdi , Ghobadi Fatemeh
Published: January 2022

Aflatoxins are more significant than other fungal toxins due to carcinogenic effects and acute poisoning. In nature, four types of aflatoxin including B1, B2, G1 and G2 and also two types of metabolic products named M1 and M2 are found. These components can pollute livestock and human feeds like corn, sorghum, wheat, soya, cottonseed, peanut and nuts. To control aflatoxin, physical separation, deactivation by heat and microbes, radiography, solvent extraction and fermentation are used. Ozone is one of the eliminating compounds of aflatoxin that has capability tocarry out the process in three status of dry, watery and moist. Ozone can eliminate fungal toxins through reacting with 8 and 9 dual bond of furan ring in aflatoxin which means initial ozonation and subsequently rearrangement to derivations and then producing aldehydes, ketones and organic acids.

Black cumin is one of the oldest medicinal plants with scientific name of (Nigella sativa L.). Plants in their growth environment are constantly faced with numerous stresses that limit their chances to develop and survive in one way or another. Drought is one of the stress-producing factors that reduce crops production rate at the global level. Iran has an arid and semi-arid climate and its average rainfall is about one-third of the global average rainfall, so it is faced with drought stresses and periodic droughts. In order to study the effects of irrigation and humic acid on yield, yield components and essential oil composition of black cumin a field experiment was arranged as split plot based on a randomized complete block design with three replications during growing season of 2013- 2014. The experiment was conducted a farm located in agricultural research institute of Zabol university in east of Iran. Irrigation intervals (6, 9 and 12 days) and four levels of humic acid concentration (0, 1, 2 and 3 kg.ha-1) considered as in main plots and sub-plots, respectively. In this study, seed yield, essential oil percentage were measured and the chemical compositions of essential oil was determined by GC/MS. Results showed that limited irrigation had significant effects on seed yield. With application of humic acid increased seed yield, essential oil percentage, p-cymene, gama terpinene and thymoquinone. The highest of p-cymene 24.6% could be obtained from taking 3 kg.ha-1 humic acid and the lowest rate 15.4% was related to not applying humic acid. Also our results indicated that the seed yield ratio under limited irrigation was found to decrease in comparison with the control. According to the results, it appears that application of 3 kg.ha-1 humic acid was the best treatment in production of yield and essential oil of black cumin in this region.

In second language teaching teachers decide how to teach, or he/she brings method of teaching in the classroom, and even in some cases it is the teacher who should select material and content for teaching. Eichler and Erens (2015) believe that the teachers have their individual reasoning for their selection of content, method, evaluation system. The reasoning of teachers is reflected in the work of other scholars, such as, “exploring teachers’ beliefs and their development are important topics in themselves” Lerman (2015). Or ‘Factors related to pedagogical beliefs of teachers and technology integration’ Liu (2011). The field of teachers’ belief is a new area in Iran, and the investigation of beliefs of teachers might be a searching of software of teachers as the main factors of process of teaching and learning. Study the teachers’ belief is helpful to investigate and discover the process of conceptualization and decision making by teachers. There are some works on English teachers’ belief, but the study about Arabic teachers’ belief was not found. This study wants to explore Arabic teachers’ belief as second language teachers in Iran. In addition to exploring the teachers’ belief, the source of beliefs was questioned. The researchers argue that inspecting of teachers’ belief should be in context, and the culture of the society in one hand, and government as authorized factor on other hand should be in spotlight of work of researchers, educators and all experts in the field. These factors at least are messy factors in all of the works in the field of teachers’ belief in Iran. Thus, by identifying and changing the beliefs many of the problems can be eliminated or improved. Sixty Arabic teachers participated in the research, and the instrument was interview.

Published: January 2022

Modified montmorilonite (Mt) as clay mineral with amino acid (M-AA) was synthesized by cation exchange method and used to remove anionic pollutants from water. The modiﬁed clay was characterized by X-ray diffraction (XRD) and zeta potential. XRD results showed that aminoacid can be intercalated into the Mt and increase the interlayer space of Mt. Positive zeta potential of modified Mt confirmed the modification of Mt with amino acid. The adsorption of pollutants onto modified Mt as a function of their initial concentration and solution pH was investigated. The removal efﬁciency was increased with increasing the pollutant initial concentration, however it decreased with increasing pH of solution. The maximum adsorption capacities of modified Mt with amino acid was 5 times larger than unmodified Mt. The regeneration studies were carried out up to 10 cycles for modified Mt and obtained results showed that modified adsorbent could also be effectively used for anionic pollutant removal from surface water for multiple adsorption-desorption cycles. adsorption, Montmorillonite, amino acid, anionic pollutant, water
Using spectral matched records to explore earthquake duration effect on inelastic response of structure
Authors: Bolboli Hossein , Mahdavian Abbas , Safi Mohammad
Published: January 2022

There are considerable debates in the technical literature regarding to effect of earthquake duration on damages in the structures. If duration of strong-motion is important, care must be taken that in design and evaluation of structures should be used records with suitable duration. In this study, time-history analysis has been done on an 8-story steel moment frame building using 49 accelerograms with different duration. Primary effect of earthquake spectral amplitude is homogenized by scaling and adjustment of records using wavelets so that they have good match to target smooth response spectrum of Iran seismic code. Comparing correlation between duration and different damage measures reveal that although duration has no important effect on maximum response measures, checking other measures show that structural damages may increases subjected to longer duration earthquake.

Published: January 2022

The bandwidth minimization problem can be used in data storage and VLSI design issues and saving large hypertext media, etc. The Matrix Bandwidth Minimization Problem involves finding matrix rows and columns permutation so that non-zero elements of the matrix A are located in a band that is as close as possible to the original diameter to minimize the amount of {max{|i−j|:aij≠.}. The Bandwidth Minimization Problem for Graphs (BMPG) is a complicated problem; hence the deterministic algorithms are not appropriate to solve these kinds of problems. The purpose of this research is to reduce the required computations through the use of heuristic algorithms and evolutionary algorithms, so that instead of using purely mathematical methods to find answers, we can turn the problem into an optimization problem through the use of collective intelligence and evolutionary algorithms and the concepts in this field. In the present paper, the use of meta-heuristic algorithm, Imperialist competitive algorithm is proposed in order to solve minimization problem. In this paper, the performance of presented algorithm with random samples has been evaluated compared with the results of genetic algorithms. The results of tests show that the Imperialist competitive algorithm can be considered as an efficient method to solve the bandwidth minimization problem for graphs.
