Disturbances of cutaneous microcirculation in patients with diabetic legs: additional parameters for a new therapeutic concept?
Authors: Bühler-Singer S , Hiller D , Albrecht H P , Seidel C , Hornstein O P
Published: July 2023

To study disturbed microcirculation involved in the pathogenesis of diabetic neuropathic plantar ulcers (DNPU), we recorded dynamic changes in laser-Doppler flux (LDF) and cutaneous oxygen tension (pcuO2) caused by short-time arterial occlusion and local heating at three different sites (forefoot, ulcer edge, lower leg) in patients (n = 14) with DNPU and healthy controls (n = 18). Significantly reduced dynamic pcuO2 parameters coincided with a significant increase of flux in the patient group. This post-stimulatory "hypoxic hyperemia" indicates a shifting of blood flux, reducing circulation of the nutritive capillaries comparable to an internal "steal effect". This may predispose to the development of DNPU when additional stresses influence the initial borderline balance, characterized by similar pcuO2 and increased flux values compared to controls. Abolishment of normal vasoconstriction in the shunt vessels by diabetic polyneuropathy is the assumed cause of increased arteriovenous perfusion and therefore raised flux values. Non-invasive testing of microcirculatory functions demonstrates characteristic disturbances in DNPU patients and could be used as additional parameters for new therapeutic concepts as the intravenous retrograde perfusion (RVP). After RVP therapy, applied to a subgroup (n = 7) of the patients, some dynamic microcirculatory parameters improved, allowing a preliminary quantitative evaluation of a therapeutic regimen.

Authors: Bergbrant I M , Broberg A
Published: July 2023

One hundred and thirty-eight children aged between 2 months and 15 years were investigated to determine the prevalence and quantity of the yeast Pityrosporum ovale. Samples were taken from the forehead and cultured on a medium containing cow's milk, glycerol, glycerol monostearate and Tween 60 as the lipid source. Eighty-seven per cent of all children were positive in the qualitative culture. The largest number of colonies of P. ovale was found among children aged 2-23 months and among children older than 9 years.

Authors: McFadden J P , Norris P G , Cerio R , Orchard G , Hawk J L
Published: July 2023

The expression of 65 kiloDalton heat shock protein (HSP65) immunoreactivity of skin biopsies from experimentally induced polymorphic light eruption (PLE) lesions was studied, to investigate its possible role as a photo-induced antigen responsible for precipitating lesions. In each subject the 24-h minimal erythema dose of solar simulated radiation was determined and an area of skin previously affected by PLE subjected to 70% of the minimal erythema dose in order to induce PLE lesions. The irradiated areas were sequentially biopsied between 0 and 6 days. ML-30, a monoclonal antibody which recognises heat shock protein 65, was used to label the sections by means of an indirect immunoperoxidase technique. In PLE patients clinical inflammation was noted by 5 h post-irradiation, with these were still present at 6 days. Increased ML-30 antibody labelling in epidermal keratinocyte and endothelial cell cytoplasm was recognisable from 1 h post-irradiation, and in dermal dendritic cells from 5 h sustained through to 6 days. In normal subjects neither clinical nor histological features of inflammation were noted after irradiation, nor any increase in HSP65 labelling. subsequent evolution of PLE-like lesions
Quinine and quinidine photoproducts can be identical.
Authors: Isaksson M , Bruze M , Gruvberger B , Ljunggren B
Published: July 2023

Quinine and its d-isomer quinidine can both cause contact allergy as well as photoallergy. Contact allergic cross-reactions between quinine and quinidine are uncommon. In allergic photosensitization the two isomers cross-react, suggesting the possibility that quinine and quinidine after UV exposure are converted to one or more common sensitizing photoproducts. Solutions of quinine and quinidine at 0.1% in ethanol 99.5% were exposed to UVA for 14 h (total dose 201.6 J/cm2). Using thin-layer chromatography, we identified 8 and 6 photoproducts from irradiated quinine and quinidine, respectively. Five of these photoproducts were seen in both chromatograms. An identical pattern with four photoproducts was found for both irradiated solutions when these were subjected to analysis in a high-performance liquid chromatography system. This study indicates that photoproducts from irradiated quinine and quinidine can be identical. This would explain the differences in the cross-reactivity pattern between contact and photocontact sensitization clinically.

UV-A-provoked localized bullous pemphigoid.
Authors: Pfau A , Hohenleutner U , Hohenleutner S , Eckert F , Landthaler M
Published: July 2023

A 71-year-old woman had noticed the development of blisters on her forehead 4 months before she was referred to our department. Treatment with oral corticosteroids resulted in complete healing, but new blisters subsequently developed on the face, neck and backs of the hands. After the possibility of phototoxic and photoallergic reactions, as well as an abnormal porphyrin profile, had been excluded, the diagnosis of bullous pemphigoid was made by histological and direct immunofluorescent examination. UV-A provocation on the upper arm produced lesions histologically and immunohistochemically typical of bullous pemphigoid. Of particular importance was the fact that the blisters were limited strictly to light-exposed skin areas.
Papular eruption in AIDS: role of demodectic mites?
Authors: Bodokh I , Lacour J P , Perrin C , Bourdet J F , Ortonne J P
Published: July 2023

We report 3 cases of pruriginous papular eruption of HIV disease, in which demodectic mites were found in the pilosebaceous follicles which were surrounded by a granulomatous inflammatory infiltrate. Papular eruption of HIV disease is a distinctive clinicopathological entity, whose pathogenicity is not known. Our observations suggest that demodectic mites might be sometimes the etiologic agents of this eruption.
Evidence for a complement-mediated inhibition and an antibody-dependent cellular cytotoxicity of dermal fibroblasts in alopecia areata.
Authors: Abdel-Naser M B , Blume-Peytavi U , Abdel-Fatah A , Orfanos C E
Published: July 2023

Immunological mechanisms have long been suggested to mediate hair loss in alopecia areata. In this process hair bulb melanocytes and dermal papilla fibroblasts are believed to be primarily involved. In the present study we further investigated the role of humoral factors in alopecia areata. Three different experiments were performed on normal human epidermal melanocytes as well as normal human dermal fibroblasts: (i) incubation with medium containing 2, 10, or 20% alopecia areata serum (n = 12 patients) for 16 h, (ii) incubation with medium supplemented with preheated alopecia areata serum (1 h at 56 degrees C) and healthy human fresh serum as a complement source (1:1) and (iii) incubation with 2, 10 or 20% alopecia areata serum but, in addition, containing peripheral blood mononuclear cells from healthy subjects (effector/target ratio, 50:1). As controls, normal human fibroblasts and normal human epidermal melanocyte cultures were also incubated with serum from healthy individuals (n = 5) under the same culture conditions. The results showed that alopecia areata serum exerted a significant stimulation of proliferation of both normal human fibroblasts (p > 0.05 at 2%, p > 0.05 at 10%, p < 0.05 at 20%), and normal human epidermal melanocytes (p > 0.05 at 2%, p < 0.05 at 10%, p > 0.05 at 20%).(ABSTRACT TRUNCATED AT 250 WORDS)

Authors: Olsson I , Asbrink E , Von Stedingk M , Von Stedingk L V
Published: July 2023

The kinetics of Borrelia burgdorferi-specific serum IgG antibody values in 74 patients treated for acrodermatitis chronica atrophicans was analysed by means of enzyme-linked immunosorbent assay. At the last clinical control, there had been no clinical signs of active infection. The serological follow-up time ranged from 12 months to 5 1/2 years (median 2 years and 1 month). In 68 (92%) of the 74 patients, a significant decrease of the specific antibody values was found within 3 years after the initiation of therapy. In 53 (72%) of the patients, this decrease was found within 15 months. Most of the patients remained seropositive during the follow-up period. The results show that a significant decline of the levels of serum IgG antibodies to Borrelia burgdorferi can be expected in the majority of patients who do not exhibit clinical evidence of persistent infection after antibiotic treatment of acrodermatitis chronica atrophicans.
Immunohistochemical demonstration of the expression of neurofilament proteins in Merkel cells.
Authors: Narisawa Y , Hashimoto K , Kohda H
Published: July 2023

The presence of immunoreactive neurofilament proteins has previously been reported in Merkel cell carcinomas but not in normal human epidermal and dermal Merkel cells. We have studied the immunoreactivity of epidermal Merkel cells for neurofilament triplet proteins (68 KD, 70 KD, 160 KD, 200 KD), using epidermal sheets prepared from the plantar skin of human adults, which enabled us to survey large numbers of Merkel cells. Neurofilament protein 200 KD-positive cells were readily identified, while neurofilament protein 68 KD-, 70 KD- and 160 KD-positive cells were largely absent. 200 KD-positive cells in the epidermis were confirmed to represent Merkel cells by a sequential immunoenzyme labeling for the simple epithelial type cytokeratin (No. 8). 200 KD-positive cells were 5.9% of the total number of epidermal Merkel cells. Despite a heterogeneous expression of neurofilament protein subspecies between the normal and transformed Merkel cells, the presence of neurofilament proteins in epidermal Merkel cells may link them to Merkel cell carcinomas.
Atypical fibroxanthoma with osteoclast-like giant cells.
Authors: Val-Bernal J F , Corral J , Fernández F , Gómez-Bellvert C
Published: July 2023

Atypical fibroxanthoma has a wide spectrum of histological appearances. A variant recently described is atypical fibroxanthoma with osteoclast-like giant cells. One case of this rare tumour is described. The tumour arose on the forehead of an 87-year-old woman in the form of a subepidermal nodule. The lesion was incompletely excised and recurred 6 months later without showing any characteristics of aggression. Six months after the second operation the patient was well and showed no signs of tumour recurrence. Immunohistological findings showed a "fibrohistiocytic" profile and were similar to those observed in other lesions rich in osteoclast-like giant cells. Flow cytometry revealed the diploid nature of the primary and the recurrent tumour. Atypical fibroxanthoma with osteoclast-like giant cells is a new variant of atypical fibroxanthoma that must be recognized by pathologists, since it can be confused with other benign and malignant tumours with a high proportion of multinucleate osteoclast-like giant cells.
Dithranol (anthralin) and 10-butyryl dithranol (butantrone) do not morphologically transform cultured C3H 10T1/2 C18 mouse embryo fibroblasts.
Authors: Viluksela M , Debets F M , Van der Hoeven J C , Männistö P T
Published: July 2023

The ability of dithranol and 10-butyryl dithranol to induce morphological cell transformation was studied in cultured C3H 10T1/2 C18 fibroblasts. The cells were incubated with different concentrations of the test compounds for 48 h and cultured for 5 weeks thereafter. At the end of the culture period the cultures were fixed, stained and examined for the presence of transformed foci. Dithranol and 10-butyryl dithranol did not increase the formation of transformed foci, while the positive control compound, 7,12-dimethylbenz(a)anthracene (DMBA), induced a high frequency of transformations significantly different from controls. Thus the in vitro cell transformation model with uninitiated C3H 10T1/2 C18 fibroblasts is not able to detect the weak tumorigenic action of dithranol and 10-butyryl dithranol which has been observed in mouse skin.

Factor XIIIa expression in juvenile xanthogranuloma.
Authors: Misery L , Boucheron S , Claudy A L
Published: July 2023

Dermal dendrocytes constitute the largest population among cells of dermatofibromas. In other histiocytic tumours, the exact nature of histiocytic cells is not known. We have searched for the presence of dermal dendrocytes in juvenile xanthogranulomas. The immunohistochemical study was performed on 9 juvenile xanthogranulomas. We used monoclonal or polyclonal antibodies: anti-XIIIa, HAM56, anti-S100, anti-NSE, anti-HLA-DR, anti-CD68 and anti-lysozyme. Phagocytic mononuclear cells (histiocytes, giant cells, Touton cells) did not express Langerhans' cell markers (S100, NSE ou HLA-DR). They weakly expressed markers of macrophages (CD68, lysozyme). There was a very strong binding by HAM56 and anti-XIIIa. This expression was more evident on xanthomatous and newly appeared tumours than on fibrous tumours. The largest population of juvenile xanthogranuloma cells appeared to be constituted by dermal dendrocytes. These cells are perhaps the key-cells of a continuum of benign tumours, from juvenile xanthogranuloma to dermatofibroma, with different stages corresponding to different proportions of dendrocytes, lymphocytes and fibroblasts.

Published: July 2023

Fokus studi ini ialah ingin melihat dan mengungkapkan bagaimana relasi kaunan dalam masyarakat Toraja. Penulis hendak melihat mengapa kaunan dipandang begitu rendah dalam masyarakat yang pada dasarnya mereka adalah manusia yang berpikir dan berperasaan. serta penulis juga hendak melihat bagaimana relasi yang terbangun dalam keadaan mereka yang terpandang hina tersebut. apakah kaunan tidak memiliki keunikan? Bukankah mereka juga adalah ciptaaan yang unik? Fenomena apa yang membuat mereka terpandang begitu rendah? Metodologi yang digunakan dalam penelitian ini ialah kualitatif dengan pendekatan fenomenologi yaitu dengan membiarkan subjek menghadirkan dirinya seadanya tanpa adanya gagasan yang membatasi. Data diperoleh dengan membaca literatur yang terkait dan wawancara mendalam (depth intrview).  Dengan menggunakan perspektif Emmanuel Levinas akan dilihat bagaimana relasionalitas kaunan. Sebagai temuan dalam tulisan ini ialah bahwa relasi kaunan ialah relasi tanggung jawab dengan konsep keluarga sebagai tanggung jawab atas kehadiran yang lain. Sejalan dengan yang Levinas sampaikan bahwa, kita mesti bertanggung jawab atas kehadiran yang lain (the other). Kaunan dipandang rendah karena ide universal. Di dalam perjumpaan antara kaunan dan To sugi’, relasi yang terbangun ialah relasi asimetris.
Mekanika Newtonian dan Signifikansi Filosofisnya
Authors: Muhamad Taufiq  , Ida Kaniawati
Published: July 2023

Mekanika Newtonian telah memotivasi berbagai ide dan penerapan sains khususnya tentang gaya, massa, gerak, dan energi pada fenomena gerak benda dan penyebabnya. Hukum Newton tentang gerak selama ini diakui sebagai salah satu pengetahuan ilmiah yang empirik dan kokoh menjelaskan berbagai fenomena alam khususnya tentang gerak. Namun demikian, perlu dilakukan kajian terkait signifikansi filosofis teori mekanika Newtonian. Artikel ini bertujuan menganalisis konsep mekanika Newtonian dalam filsafat ilmu dan signifikansinya (aspek ontologi, epistemologi dan aksiologinya). Artikel ini disusun melalui studi literatur dengan metode critical literature review menggunakan lima tahapan, yaitu menentukan topik, menentukan kriteria inklusi dan eksklusi, melakukan pencarian literatur, mengevaluasi literatur yang ditemukan, dan menulis laporan hasil studi. Berdasarkan hasil analisis literatur, disimpulkan bahwa sejarah perkembangan teori Mekanika Newtonian merupakan bagian dari perkembangan mekanika klasik hingga mekanika modern. Teori Mekanika Newtonian atau juga dikenal sebagai Hukum Newton tentang gerak diperkenalkan dan berkembang pada era Periode Awal Sains (1550–1800 M). Mekanika Newtonian dalam tinjauan ontologi merupakan pemikiran yang panjang mengenai konsep gerak benda dan membahas mengenai gaya yang bekerja pada benda. Secara epistemologis, teori Mekanika Newtonian tidak semata-mata bersumber dari gagasan Isaac Newton, melainkan merupakan hasil usaha kolektif sekelompok ilmuwan yang mengkaji dan mendalami fenomena gerak alam. Dari perspektif aksiologis, Mekanika Newton menawarkan berbagai keuntungan praktis dalam kehidupan sehari-hari dan memiliki arti penting, khususnya dalam bidang pendidikan fisika, khususnya mekanika. Ini melampaui sekadar eksplorasi fakta, prinsip, atau hukum karena mencakup nilai-nilai moral yang dapat ditanamkan kepada peserta didik sebagai alternatif pendekatan pendidikan karakter.
The Perspective of Plato Concerning the Position of Love in Philosophy Analysis of The Symposiu
Authors: Syaebani Muhammad Irfan , Yuwono Untung , Ekosiwi Embun Kenyowati
Published: July 2023

Plato was the first philosopher who discussed love philosophically. The discussion can be found in his work entitled Symposium. Through text analysis of Symposium, the perspective of Plato about love and the position of love in philosophical discourse can be concluded. For Plato, ultimate love does not have a relation to the body anymore. Plato believed that love is hierarchical, and it ascends from the lower level to the higher level as illustrates in Scala Amoris. The ultimate love is about a mental state which aims to gain absolute beauty and it is the highest level of love. However, in romantic relationships, love is not only about the mental state but also physical contact because romantic love relates to sexual things such as sexual intimacy. And according to Plato, love that still has attachment to the body is the lowest level of love. Thus, Plato's perspective about romantic love cannot be said as positive because romantic love strongly relates to the body. Plato believed that the highest level of love has left body behind, and it only focuses on mental aspiration.

Agama adalah fitrah bagi setiap umat manusia, dengan begitu kajian tentang agama selalu eksis sepanjang zaman. Agama telah menjadi sentral objek penelitian oleh para sarjana baik di dunia Timur atau Barat. Salah satu ilmuan Barat yang mengkaji agama adalah Max Weber, kajian agamanya sangat erat dengan tindakan sosial yang ada di masyarakat. Kendati setiap tindakan sosial, kelompok, memiliki makna subyektifitas baik secara individu atau kelompok. Teori tindakan sosial dibagi menjadi empat bagian diantara: Pertama, tindakan afektif, kedua, tindakan tradisional, Ketiga, tindakan rasional instrumental, Keempat rasional nilai. Tujuan dari penulisan ini adalah untuk mengkaji pandangan Max Weber tentang peran sosial dari agama. Penelitian ini menggunakan metode penelitian kualitatif sebanyak teks dengan sumber data penelitian dari studi pustaka baik berupa buku maupun laporan penelitian. Bagi Max Weber, agama adalah kepercayaan pada kekuatan sakral. Lebih dari kepercayaan, masing-masing agama seperti Islam, Kristen, Budha dan Yudaisme memiliki kebiasaan sosial yang berbeda satu sama lain. Lebih jauh lagi, agama berkaitan erat dengan sesuatu yang supranatural dan universal yang diakui semua umat manusia.

Authors: Banerjee Sumit Kumar , Lanta John
Published: July 2023

The well-known SIR models have been around for many years. Under some suitable assumptions, the models provide information about when the epidemic occurs and when it doesn’t. The models can be restructured by incorporating birth & death rate, portion of population vaccinated, carrying capacity of population, saturation rate, growth rate, time delay and immunization to analyze the outcome mathematically. In this regard several SIR models including birth, death and immunization as well as bifurcation analysis associated with disease free and epidemic equilibrium have been studied. Findings of this research are with some suitable assumptions how these incorporated parameters as well as bifurcation analysis can play an important role in determining epidemic status in the society in more reliable and convenient way.

Environmental Degradation in the Nepalese Society: An Eco-Critical Approach
Authors: Verma Rakhi
Published: July 2023

The paper aims to explore the direct or indirect link between the patriarchal Nepalese society and the degradation of Nepal’s forestry and environment. The males of Nepal have been dominating and disrespecting women as the inferior sex for centuries, and thereby treating natural resourses as feminine, weak to be manipulated and consumed objectively for their benefits. The research tool taken to carry out the research is eco-feminism. To notice the relationship between gender and natural resources of Nepal, the theoretical concerns of such eco-feminist critics as Greta Gaard and Vandana Shiva are chiefly focused on. The Nepalese society, like most of the South-Asian societies, is a male-dominated society. It exploits both women and nature regarding them to be inferior. The chief finding is that the natural resources of Nepal such as air, water, green fields, climate, land, forestry, minerals, environment, and the species of Nepal have been getting threatened because of the Nepalese patriarchal society. The Nepali people exploit nature as carelessly as they have been exploiting women. It is assumed that the research scholars interested in exploring Nepalese society from the perspective of eco-feminism can take the article as a reference.

Published: July 2023

In Oman, novice in-service primary English teachers struggle with the theoretical content of professional training programs, which impedes knowledge acquisition and transfer into teaching practices. This research stems from the benefits of continuous professional development, communities of practice, and practical and reflective learning on teachers’ exposure to teaching methods resulting in improved teaching skills and techniques. Considering the affordances of mobile learning, Padlet training was designed as an alternative to face-to-face programs during the Covid-19 pandemic to support in-service primary teachers with online synchronous teaching. The objectives were to improve participation, content acquisition, and knowledge transfer into teaching practices. Six novice Omani in-service English primary teachers participated in training for seven months. The data from semi-structured interviews, observations, interactions, peer feedback, and teaching e-portfolios were analysed with a systematic grounded theory three-step coding, which were performed until model emergence and saturation. The findings confirmed the contributions of the Padlet training to the enhancement of content acquisition and transfer due to ubiquitous access, simplified multimedia content, hands-on practice, instructor-peer feedback, and digital self-reflective e-portfolios. The teachers were enthusiastic about the program, which led to a virtual circle. Participants viewed Padlet as an engaging platform to host a community, access, create, and share content. Ubiquitous access and support within a peer community resulted in regular attendance, engaged participation, and increased confidence, which led to improved content acquisition and content transfer. The resulting Padlet training model presented in this article could be replicated to design mobile professional development training programs in similar contexts.
Classroom Discourse Analysis of Computer-Mediated Communication during COVID-19
Authors: Bani Alkahtani Mona
Published: July 2023

In March 2020, the Saudi government announced that school and university courses were to be held online to control the COVID-19 outbreak. A sudden yet smooth movement occurred from traditional face-to-face classrooms to online courses. This shift influenced the nature of classes, the nature of the interaction, and the participants’ roles. Interaction in online classes is viewed as a form of computer-mediated communication. This paper explores the nature of computer-mediated communication in online courses at one of the major research universities in Riyadh during the COVID-19 pandemic. Using an in-depth qualitative analysis of Walsh’s (2006) framework of Self-Evaluation of Teacher talk, this study examines the nature of classroom discourse and interactions among level six students who took a content course in English and lectures were transcribed for this study. Results answer questions regarding the common interaction modes and features and how efficient they are to encourage participation during Computerized Mediated Communication. Analysis reveals that using traditional interactional features is not suitable in virtual classes.Teacher dominated classes with excessive IRFs patterns do not cultivate interaction in Computerized Mediated Communication. New modes of communication and discursive features using more interactive tools and engaging features such as referential questions promote interaction. Results provide an insight into the nature of interaction in online university classrooms. It also adds to the current literature on Computerized Mediated Communication interaction to enhance the existing practices done in classrooms.

Tandan Kosong Kelapa Sawit (TKKS) merupakan limbah yang banyak ditemukan di pulau Sumatra dan berpotensi menjadi penguat dalam sebuah komposit. Pemanfaatan TTKS masih sangat terbatas sehingga perlu dilakukan penelitian lebih lanjut tentang komposit berpenguat serat TKKS. Penelitian ini bertujuan untuk mengetahui pengaruh variasi sudut anyaman terhadap kekuatan tarik komposit berpenguat serat TKKS. Proses pembuatan komposit dengan metode compression molding dengan perbandingan komposisi 60% resin dan 40% serat. Variasi sudut anyaman yang digunakan adalah 0°/90°, 15°/105°, 30°/120°, dan 45°/135°. Pengujian kekuatan tarik dengan standar ASTM 3039 dan dilakukan pengamatan patahannya. Hasil pengujian tarik menunjukkan kekuatan tarik terbesar adalah 12,88 MPa pada sudut anyaman 0°/90°. Hal ini disebabkan semakin banyak serat searah dengan gaya tarik maka semakin tinggi kekuatan tarik yang didapatkan.
