Study of the basic laws of dissolution of gold and copper in solutions with an ultra-low concentration of sodium cyanide
Authors: Vasilkova A. O. , Khmelnitskaya O. D. , Voiloshnikov G. I.
Published: July 2023

The work sets out to study the basic physicochemical dissolution patterns of gold, copper, and natural copper-containing minerals (chalcopyrite, bornite and azurite) in solutions with an ultra-low concentration of sodium cyanide (from 0.102∙10-3 to 4.08∙10-3 mol/L). The influence of various factors on the rate of dissolution of Au and Cu in solutions with ultra-low NaCN concentrations was studied by the rotating disk method; for natural copper minerals, the powder diffraction method was used. The concentration of gold and copper in solutions was determined by atomic absorption analysis. The chemical composition of the studied copper minerals was determined using the X-ray phase method, while the specific surface of the minerals was detected using a laser granulometer. The process of gold dissolution is shown to proceed in both diffusion and kinetic regions. In the diffusion region, the rate constant was 0.334∙10-6 L∙cm-2∙s-1/2∙rad-1/2; in the kinetic region – 0.919∙10-6 L∙cm-2∙s-1/2. The calculated value of the apparent activation energy for the diffusion region was 22.5 kJ/mol; for the kinetic region – 40.1 kJ/mol. The addition of glycine to a solution with an ultra-low concentration of sodium cyanide is shown to increase the specific dissolution rate of gold by 1.2 times: from 0.692∙10-9 to 0.82∙10-9 mol/cm2∙s. The process of copper dissolution is shown to take place in the diffusion r egion. The rate constant was 0.496∙ 10-6 L∙cm-2∙s-1/2∙rad-1/2 at an activation energy of 17.0 kJ/mol. With a fractional supply of sodium cyanide, the dissolution rate of copper minerals is reduced by 10–30% compared to a single load. The calculated apparent activation energy values for chalcopyrite, bornite, and azurite were 22.03, 24.2, and 24.1 kJ/mol, respectively. Thus, the use of ultra-low concentrations of NaCN in the process of cyanidation of gold and copper has a positive effect, which can be used i n the processing of gold-copper raw materials to significantly reduce the consumption of sodium cyanide.

Published: July 2023

This work evaluated the multi-element concentration in grape must and soil samples employing inductively coupled plasma optical emission spectrometry (ICP OES), after microwave-assisted digestion. The study aimed to establish a profile of seven grape varieties produced in Petrolina, region Submedium São Francisco, Brazil. Principal component analysis (PCA) clearly showed a good separation of samples in terms of mineral constituents. Although some soil samples showed concentrations of Co, Cu and Ni higher than the prevention values (VP), no sample exceeded the values stipulated for an intervention in agricultural soils based on Resolution No. 420/2009 of the National Council for the Environment (CONAMA). So, the results obtained contribute to food mineral composition table, as it brings unprecedented information about the concentration of the elements in seven grape varieties, providing indicators of geographic location, and contributing to the preliminary construction of a geochemical base of the regional soil.

Published: July 2023

Long non-coding RNAs (lncRNAs) typically refer to non-protein coding RNAs that are
longer than 200 nucleotides. Historically dismissed as junk DNA, over two decades of research have revealed
that lncRNAs bind to other macromolecules (e.g., DNA, RNA, and/or proteins) to modulate signaling
pathways and maintain organism viability. Their discovery has been significantly aided by the
development of bioinformatics tools in recent years. However, the diversity of tools for lncRNA discovery
and functional prediction can present a challenge for researchers, especially bench scientists and clinicians.
This Perspective article aims to navigate the current landscape of bioinformatic tools suitable
for both protein-coding and lncRNA genes. It aims to provide a guide for bench scientists and clinicians
to select the appropriate tools for their research questions and experimental designs.

In this paper, we report the conductivity behavior in the insulating phase at zero magnetic field. We have theoretically investigated the temperature dependence of the electrical conductivity of wet spun graphene fiber and its composites. The temperature dependence of electronic conduction follows the law σ~exp⁡〖(E_0/E)〗^m. Indeed, the electronic conduction is dominated by the coexistence of two regimes: Efros-Shklovskii variable range hopping mechanism where m=1/2 and the activated mechanism where m=1. By using two different methods: the numerical method based on the calculation of the percentage deviation Dev (%) and the conductance curve derivative analysis method which is based on the logarithmic derivative function W=dlnσ/dlnE, we have found the exponent m is close to 1.

The Effect of Micro and Nano Material on Critical Heat Flux (CHF) Enhancement
Authors: Sharef Enas M. , Ali Jamal M. A
Published: July 2023

The Nano materials play a very important role in the heat transfer enhancement. An experimental investigation has been done to understand the behaviors of nano and micro materials on critical heat flux. Pool boiling experiments have used for several concentrations of nano and micro particles on a 0.4 mm diameter nickel chrome (Ni-Cr) wire heater which is heated electrically at atmospheric pressure. Zinc oxide(ZnO) and silica(SiO2) were used as a nano and micro fluids with concentrations (0.01,0.05,0.1,0.3,0.5,1 g/L), a marked enhancement in CHF have been shown in the results for nano and micro fluids for different concentrations compared to distilled water. The deposition of the nano particles on the heater surface was the reason behind the enhancement of the wettability of the surface which will increase the CHF, this nano particles deposition will form a porous layer and the mechanism of the formation of this layers is that as vapor bubbles grow, the evaporating liquid in the micro layer leaves behind Nano particles which then will be concentrated at the base of the bubble to form this pours layer. The higher wettability can produce CHF enhancement, the enhancement ratio of Nano fluid is observed to be higher than that of micro fluid, the optimum   enhancement ratios of nano fluid is (1 g/l) which observed to be 9.2 % for ZnO and 8.7% for Sio2, and also (1 g/l) for micro fluid which observed to be   8.1%for ZnO and 7.4%for SiO2.

Published: July 2023

Содержание сахара в сырье и пищевых продуктах в значительной мере определяет их полноценность и качество. Поэтому большое внимание уделяется методам контроля содержания этого важного ингредиента. Предложена экспрессная методика определения общего сахара: выбран способ гидролиза сахарозы, уточнены условия (оптимальная температура, время, объем соляной кислоты) полного гидролиза сахарозы без разложения продуктов реакции, а также без гидролиза лактозы, мальтозы и декстрозы. Проведено сравнение двух методик с разными условиями гидролиза: стандартного метода (Бертрана) по ГОСТ 5903 89 (гидролиз сахарозы проводили при температуре 67 °C) и ускоренного феррицианидного метода, включающего гидролиз сахарозы при температуре 100 °C. Получены достоверные данные при значительном (в 5 раз) сокращении времени гидролиза сахарозы, а следовательно, и длительности всего анализа по сравнению со стандартным способом определения сахара. Ускоренную методику по определению редуцирующих веществ (РВ) и общего сахара в продуктах хлебопекарного и кондитерского производства можно считать приоритетной среди химических методов исследования и рекомендовать ее для поточного аналитического контроля.
Tafakkur: A Contemplation of Students’ Spiritual and Emotional Intelligence (in The Perspective of Sufism & Transpersonal Psychology)
Authors: Nufus Dewi Hayati , Sururin Sururin , Sodiq Akhmad
Published: July 2023

The phenomenon of the educational process creates students who frequently feel fatigue/boredom which has an impact on increasing levels of anxiety, suppression, repression, and depression. Various learning methods are applied to be able to overcome the boredom/burden of fluctuating thoughts and emotions, namely through implementing changes that tend to involve one's personal internal strength. The practice of contemplation is a training concept that is integrated with several schools. The purpose of this academic paper is to advance the concept of tafakkur in the discipline of education and establish a framework for developing instruments that enhance students' emotional and spiritual intelligence. Employing a qualitative research approach with a literature review and examination of information from Islamic scientific sources (the Qur'an and the Sunnah), as well as contemporary Islamic literature and Western literature for comparison. Description of a few previous research investigations on student therapy for anxiety and depression. Conclusions of the analysis of the concept of tafakkur from two perspectives, namely Sufism and transpersonal psychology, provide the foundation for thinking about school students' learning theory, which is inherent in the Islamic religious education curriculum because the content of tafakkur learning activities can present tawhid values, which function as the primary fundamentals of Islamic religious education. The utilization of tafakkur as a teaching tool will assist students to focus on their studies, which has implications for improving their spiritual and emotional intelligence. This provides students a strong soul and mentality as well as enables them to deal with the pressures and challenges of both the present and the future periods of globalization.

Published: July 2023

This article discusses the actual challenges in realizing an Islamic education curriculum in Aceh. As a province that was given permission to enforce the application of Islamic Sharia, including in the field of education, in fact, Aceh has not succeeded in realizing the implementation of an Islamic education curriculum. In fact, Aceh Qanun Number 9 of 2015 concerning the Implementation of Education mandates that the education curriculum in Aceh can be taught Islamically. However, until now the guidelines for implementing the Islamic education curriculum have not been successful. So, what is the reason and what are the challenges faced? This is what is answered in this study. This research method is qualitative where the interviewees are in-depth education stakeholders, both executive and legislative. The results show that there are a number of challenges in realizing Islamic education in Aceh such as Islamic curriculum guidelines that are not yet concrete, budget restrictions by the Aceh Government, problems in a top leader, the absence of a writing team, and clashes with the central government to the weakness of the executive branch. The results of this study are expected to be used as evaluation material for the success of the agenda for realizing Islamic education in Aceh.
Back to Nature: Sebuah Tinjauan Filosofis tentang Konsep Pendidikan Rousseau
Authors: ZA Tabrani
Published: July 2023

Rousseau's fundamental views or assumptions which discuss anthropology and epistemology lead to how children learn. These assumptions on human nature are related to the rapid development of human civilization, especially in this modern era. The purpose of human life which was originally good is reduced only by various developments of civilization so that humans increasingly leave their integrity as humans who are free, autonomous, and of good nature. This fact made Rousseau aware that the culture which had been admired and proud of by many people in Europe was in fact not the pinnacle of human life but a reflection of the decay of civilization. Culture, art, and science, along with technology, seem to have destroyed humanity and have created unhealthy dependence and injustice. One of the philosophers who criticized the situation of human civilization and proposed a revolutionary educational system in the early modern era was Jean Jacques Rousseau. Emile is one of Rousseau's most revolutionary works on education. In his book, Emile, Rousseau puts his thoughts on education back to nature in the book. Rousseau's view of education is broken down by age group and emphasizes a return to nature. Emile, as the main character, grows up in accordance with natural conditions and learns by the Rousseau method which emphasizes learning according to development and natural inquiry processes. It aims to achieve fundamental changes in education to free the individual from the shackles of civilization. Civilization is not only detrimental to society; it also harms the individual. Education should encourage children's self-expression and development.

State-of-the-art review on WWTPs in Antioquia: levels, technologies, flaws and operational setbacks
Authors: Londoño Vélez Santiago , Molina Pérez Francisco José
Published: July 2023

The number of wastewater treatment plants (WWTPs) in Antioquia (Colombia) increased 74 % over the last nine years. This increase brought to light we need for a unified guide to prevent flaws in the future WWTPs. Therefore we set out to design a guide to meet this new need. To achieve this design we had four main stages. First, we chose the 89 WWTPs from previous experience that we had in the operational stage. Second, we classified these WWTPs into levels and technologies. Third, we described various flaws in these WWTPs. Fourth, we designed a guide with these WWTPs technologies mostly used in Antioquia. Here we described that these WWTPs mostly used a combination of various levels and technologies. These levels were pre-treatment, primary treatment, secondary treatment, and sludge treatment. These technologies were primary sedimentation basins (with inclined plates), UASB reactors, anaerobic packed-bed reactors, anaerobic sludge digesters, and conventional sands beds. These WWTPs mostly served a population of less than 30.000. And these WWTPs had various flaws and operational setbacks. These flaws were the inappropriate localization of these WWTPs, low retention times in these anaerobic packed-bed reactors and the lack of proper size in these conventional sands beds. These setbacks were the unequal distribution 174 REVISTA PRODUCCIÓN + LIMPIA–Vol. 18 No 1 – enero/junio – 2023 / S.

With the increased growth of IoT devices, the supply of power to
low-power devices, such as sensors and communication modules, has become
problematic. This study develops a rectifier circuit that generates a
large DC output voltage from the received high-frequency signal,
targeting the frequency band of 470 to 710 MHz used in terrestrial
digital broadcasting towers. The size of our proposed rectifier is 35 ×
57 mm.
Next, we connect devices, such as a temperature and
humidity sensor and Bluetooth low energy module to the developed
rectifier circuit, and transmit data without a power supply. We validate
a sustained operation of the sensor system at a distance of 7.5 km from
a TV broadcasting tower.
A Multistage Distributionally Robust Optimization Approach for Generation Dispatch with Demand Response under Endogenous and Exogenous Uncertainties
Authors: Huang Yiwen , Huang Wentao , Tai Nengling , Li Canbing , Li Ran , Yu Moduo
Published: July 2023

Decision-dependent (endogenous) uncertainties (DDUs), as a new type of
uncertainties revealed recently, couple dispatch decisions with
uncertainty parameters and thus render power system dispatch more
challenging. However, most previous works handled various DDUs via
stochastic programming (SP) or robust optimization (RO) in a two-stage
framework, which undoubtedly introduces the drawbacks of SP and RO, and
cannot meet the nonanticipativity requirements in power scheduling. In
this paper, we propose a multistage distributionally robust optimization
(DRO) method for generation dispatch with demand response (DR)
considering the DDUs of deferrable loads and the decision-independent
(exogenous) uncertainties (DIUs) of wind power and regular loads. By
analyzing the structure of decision-dependency parameters, a novel
data-driven decision-dependent ambiguity set is proposed, which provides
a generic framework for formulating DDUs and DIUs simultaneously. Then a
multistage DRO model with nested max-min structure is developed to
integrate the merits of DRO and nonanticipativity into generation
dispatch. The proposed model is solved by tailored reformulation method
and improved stochastic dual dynamic integer programming (SDDiP). Case
studies illustrate the effectiveness of the proposed approach by
comparing with the multistage SP, RO, and decision-independent DRO
methods.
The Ancestral Karyotype of the Heliantheae Alliance, Herbicide Resistance and Human Allergens: Insights from the Genomes of Common and Giant Ragweed
Authors: Laforest Martin , Martin Sara , Bisaillon Katherine , Soufiane Brahim , Meloche Sydney , Tardif François , Page Eric
Published: July 2023

Ambrosia artemisiifolia and Ambrosia trifida (Asteraceae) are important
pest species and the two greatest sources of aeroallergens globally.
Here we took advantage of a hybrid to simplify genome assembly and
present high quality chromosome level assemblies for both species. These
assemblies show high levels completeness with BUSCOs of 94.5% for A.
artemisiifolia and 96.1% for A. trifida and LTR Assembly Index values
of 26.6 and 23.6, respectively. The genomes were annotated using RNA
data identifying 41,642 genes in A. artemisiifolia and 50,203 in A.
trifida. More than half the genome is comprised of repetitive elements,
with 62% in A. artemisiifolia and 69% in A. trifida, and this is
similar to other species in the Heliantheae alliance . Single copies of
herbicide resistance associated genes PPX2L, HPPD, and ALS where found,
while 2 copies of the EPSPS gene were identified; this latter
observation may reveal a possible mechanism of resistance to the
herbicide glyphosate. The evolution of genome structure has differed
among these two Ambrosia species. The genome of A. trifida has undergone
greater rearrangement, possibly the result of cataclysmic reorganization
through chromoplexy. In contrast, the genome of A. artemisiifolia
retains a structure that makes the allotetraploidization of the most
recent common ancestor of the Heliantheae alliance the clearest feature
of its genome. When compared other Heliantheae alliance species, this
allowed us to reconstruct the common ancestor’s karyotype – a key step
for further development of our understanding of the evolution and
diversification of this economically and allergenically important group.
Urbanization alters the relative importance of local and landscape factors affecting plant communities in the Tokyo megacity
Authors: Iwachido Yuki , Sasaki Takehiro , Uchida Kei
Published: July 2023

Plant communities are impacted by local (related to environmental
filtering) and landscape (related to dispersal limitation) factors.
While previous studies have shown that the relative importance of these
factors varies depending on different aspects (i.e., spatial-temporal
scale), little is known about how they are altered by urbanization—a
significant threat to biodiversity. This study evaluates the relative
importance of local environmental (local factors), landscape, and
spatial (landscape factors) variables that influence plant communities
in 34 urban green spaces comprising two different habitats (forests and
grasslands) along the urban–rural gradients in the Tokyo megacity,
Japan. To continuously assess the relative importance of each factor
along the urban–rural gradients, we extracted 1,000 landscapes within a
certain range that contained several sites. Subsequently, the relative
importance of each factor and urbanization rate (proportion of
artificial built-up area) was estimated at each landscape. The relative
importance of the local factor increases, while the landscape factor
decreases with urbanization, and the local factor becomes a primary
factor in highly urbanized areas in forest habitats. However, the
relative importance of the local factor decreases, whereas the landscape
factor increases with urbanization in grassland habitats for native
species. Collectively, these findings suggest that city size and target
habitat characteristics must be considered when predicting changes in
plant communities caused by urbanization.

Effective target assignment plays a crucial role in maximizing the
efficiency and success of cooperative air combat involving multiple UAVs
in complex and dynamic environments. Accurate target threat assessment
is essential for successful target assignment. This study proposes a
threat assessment method that considers multiple threat factors of UAV
targets and introduces an uncertain information representation technique
using interval-valued intuitionistic fuzzy number. To achieve the fusion
of multi-moment target information, weights are assigned to the time
series using the normal distribution method. Furthermore, a weight
optimization model is presented to integrate the threat factor weights
obtained through the AHP method and the entropy method. For solving the
multi-weapon multi-target assignment problem, a target assignment method
based on the VNS-IBPSO algorithm is introduced. This method improves
upon the limitations of the BPSO algorithm, such as limited local search
capability and premature convergence, by combining variable neighborhood
search (VNS) and an improved binary particle swarm optimization
algorithm (IBPSO). The effectiveness of the proposed method is validated
through simulation experiments, which demonstrate its ability to quickly
and accurately complete target assignment tasks. This method provides an
effective solution for the coordination task allocation of multi-UAV
cooperative air combat.

Domestication and intensive management practices have significantly
shaped characteristics of modern crops. However, our understanding of
domestication’s impact had mainly focused on aboveground plant traits,
neglecting root and rhizospheric traits, as well as trait-trait
interactions and root-microbial interactions. To address this knowledge
gap, we grew modern ( Hordeum vulgare L. var. Barke) and wild
barley ( H. spontaneum K. Koch var. spontaneum) in large
rhizoboxes. We manipulated soil microbiome by comparing disturbed
(sterilized soil inoculum, DSM) versus non-disturbed (non-sterilized
inoculum, NSM) microbiome Results showed that modern barley grew faster
and increased organic-carbon exudation (OC ) compared
to wild barley. Interestingly, both barley species exhibited accelerated
root growth and enhanced OC under DSM, indicating
their ability to partially compensate and exploit the soil resources
independently of microbes if need be. Plant trait network analysis
revealed that modern barley had a denser, larger, and less modular
network than wild barley indicating domestication’s impact on trait
coordination. Further, soil microbiome influenced specific network
parameters. While the relative abundance of bacteria didn’t vary between
wild and modern barley rhizospheres, species-specific core bacteria were
identified, with stronger effects under DSM. Overall, our findings
highlight domestication-driven shifts in root traits, trait
coordination, and their modulation by the soil microbiome.
Comparison of Candida albicans adherence to human corneocytes from various populations.
Authors: Srebrnik A , Segal E
Published: July 2023

Epidemiological data indicate that patients suffering from diabetes, hypothyroidism, obesity, or following prolonged treatment with antibiotics, corticosteroids or oral contraceptives, have an increased tendency to develop cutaneous candidiasis. Since it is generally believed that attachment of microorganisms to host cells is an initial step in the evolution of infection, the aim of the present study was to investigate whether cells from susceptible individuals have increased capacity to bind the fungus. Corneocytes collected from the forearms of individuals of these susceptible groups were exposed in vitro to Candida albicans and adhesion to the cells was evaluated in comparison with adherence to cells from a non-susceptible population. Adherence in vitro was assayed microscopically and evaluated quantitatively by two parameters: 1) percentage of adherence - number of corneocytes with adhering yeasts on their surface, and 2) the total number of adhered yeasts. Results of the study revealed that the mean percentage of adherence and the mean total number of yeasts adhering to cells from individuals of the susceptible populations was twice as high as values in a healthy population. Statistical analysis of the data by Student's t-test indicated that the difference was significant (p less than 0.001).

Authors: Nigale V , Trasi S S , Khopkar U S , Wadhwa S L , Nadkarni N J
Published: July 2023

A 5-year-old physically and mentally retarded female child born of non-consanguineous parents, who had had disseminated skin lesions for 4 1/2 years, is presented. She had persistent neonatal jaundice associated with clay-coloured stools and generalized pruritus which receded by the age of 2 years. Examination revealed characteristic facies, moderate hepatosplenomegaly, cardiac murmur and widespread smooth yellow papules and nodules on ears, trunk, bony prominences and palms. Ophthalmic examination revealed corneal opacities. Liver function tests and lipidogram were abnormal. A diagnosis of Watson-Alagille Syndrome was made on the basis of characteristic facies, xanthomatosis and cholestatic jaundice.
3H-thymidine labelling of epidermis and dermal infiltrate in psoriatic erythroderma
Authors: De la Brassinne M , Lachapelle JM.
Published: July 2023

The comparative pattern of 3H-thymidine (3H-T) pulse labelling in lesions of psoriatic erythroderma (3 cases) and of psoriasis vulgaris (20 cases) has been studied by means of radioautography. In the epidermis, no difference was noted between the two types of lesions concerning the epidermal 3H-T labelling index (L.I.) and the localization of labelled cells. The 3H-T L.I. of "round" cells infiltrating the dermis was much higher in lesions of psoriatic erythroderma (4.03 +/- 0.56%) than in lesions of psoriasis vulgaris (0.62 +/- 0.21%), and the difference is highly significant (p less than 0.0001). The findings indicate that most of these labelled cells could well be lymphoblasts, suggesting that an immunological process is possibly involved in the pathogenesis of psoriatic erythroderma.
Surgical treatment of paronychia granulomatosa hallucis
Authors: Jemec B , Anderson JE.
Published: July 2023

Paronychia granulomatosa is a complication incident to unguis incarnatus; surgery for this complaint was performed on 26 patients with 52 granulomas. The operation was first described by Bartlett in 1937. The postoperative hospitalization was 3 days and the patients returned a week later to have the sutures removed. After the operation, ten remaining granulomas were observed of which 6 were cured by operation and 2 conservatively, leaving 2 under continuing conservative treatment (5 months and 1 month, respectively).

Surface ultrastructure of human skin
Authors: Hashimoto K , Kanzaki T.
Published: July 2023

The normal human skin surface was studied with a combination of scanning electron microscope, surface replication method, and transmission electron microscope. All specimens were prepared with the critical point drying (CPD) method. Horny cells were found to stack up in columnar fashion with their peripheries overlapping. The surface of a non-nucleated horny cell, therefore, showed a dome-shaped elevation in the center, transmitting the nuclear bulge of the underlying granular cells; parallel double lines at the periphery representing its true cell border and depressed, step-like imprint of the cell border of the cell which once overlapped; and on high magnification the true surface of the separated desmosomes. The surfaces of the horny cells showed many bizarre marks but were relatively smooth. The underside of the surface horny cells, however, bore villi except in areas overlapping the periphery of the underlying cell. Tissue cultured keratinocytes also stacked up when the keratinized and the cell periphery also overlapped. However, the overlapped cell border did not leave the imprint on the underlying cell, probably because of the lack of pressure from above.

Histological and histochemical investigations of lupus erythematosus in the skin and the oral mucosa
Authors: Gisslén H , Heyden G.
Published: July 2023

Skin and oral lesions of chronic discoid lupus erythematosus from 6 patients have been investigated histologically and histochemically. Intra-individual comparisons between skin and oral lesions and intrasection comparisons between clinically affected and unaffected regions were performed. Enzyme histochemical recordings consisted of oxido-reductase and hydrolase activities. A high degree of correlation was noted in the intra-individual comparisons. The intrasection comparisons provided information concerning metabolic dynamics of the disease. The data obtained support the view that serious vascular changes are involved in the development of the changes in the overlying epithelium. The enzyme histochemical results agreed generally with histological data and proved to be a valuable diagnostic aid.
Necrolytic migratory erythema and glucagon cell tumour of the pancreas: the glucagonoma syndrome. Report of two cases
Authors: Pedersen NB , Jonsson L , Holst JJ.
Published: July 2023

Two cases of necrolytic migratory erythema are described. Both patients also suffered from anaemia, weight loss, hypersedimentation and carbohydrate intolerance. A solitary pancreatic tumour was found in both cases-- at autopsy in one and at laparotomy in the other. Microscopic examination of skin biopsies showed necrolysis of superficial epidermis. Both patients had extremely elevated plasma concentrations of pancreatic glucagon. By means of specific staining and immunofluorescence techniques the tumours were shown to consist of glucagon-containing alpha2-cells. It is concluded that these patients suffered from the newly described glucagonoma syndrome.
The activation of antigens of the basement membrane zone by proteolytic enzymes in vitro
Authors: Remy W , Bockendahl H , Stüttgen G , Petersen G.
Published: July 2023

Following brief exposure of cryostat sections of human skin to the action of proteolytic enzymes (papain or trypsin), there was a pronounced increase in the antibody binding sites of the basement membrane zone, shown in indirect immunofluorescence by an increased intensity in fluorescence of the basement membrane zone as compared with preparations which had not previously undergone incubation, and by an increase of 5-6 (papain) or 4-5 (trypsin) titre dilution steps. This effect was practically absent when guinea-pig tongue was used as the antigenic substrate. In conjunction with findings published in the literature, our results can be interpreted as indicating that the activation of the basement membrane zone antigens by proteolytic enzymes is associated with an increase in antigenicity which results in the formation of "auto-antibodies" of the basement membrane zone antibody type.

The role of oxygen in the photodamaging effect on erythrocytes of some photoallergic and phototoxic compounds
Authors: Schothorst AA , Suurmond D.
Published: July 2023

Red blood cells irradiated with longwave ultraviolet light in the presence of a number of photoallergic or phototoxic compounds showed a marked loss of K+ ions. This process was strongly restricted by anaerobic conditions. During irradiation, oxygen was consumed. Since pre-irradiated photosensitizers were not toxic to erythrocytes, it is concluded that during irradiation, oxidative processes take place in the erythrocyte. The concentrations of the investigated photoallergic compounds required to induce photohaemolysis, were several times higher than those required for the phototoxic compound protoporphyrin. These findings indicate that photoallergic compounds, like the photodynamic compounds, also have photo-oxidative capacities, but to a much lower degree.
