Egyptian Expeditionary Inscriptions of the Fourth Dynasty and Ancient Natural Landscapes of the Western (Libyan) Desert

Libyan Desert

The Middle Holocene epoch in northeastern Africa was marked by a steady trend towards aridization. However, the transformation of ecosystems and natural landscapes was gradual and had a complex nature. This change directly affected the development of the first ancient Egyptian centralized state as well as the development of its resource base beyond the Nile Valley. This study addresses the problem of using ancient Egyptian epigraphic sources (expeditionary inscriptions) for the study of both paleolandscapes and ecosystems of the Western (Libyan) Desert and the possible socio-economic impact of their change. The author studies several graffiti, which are believed to have preserved information on natural conditions near the Dakhla oasis and in the region of Wadi Toshka during the time of construction of the great pyramids (Fourth Dynasty). The author concludes that it is quite easy to make misleading assumptions when interpreting expeditionary artefacts. At the same time, as an example with an unusual toponym from the quarries near Wadi Toshka demonstrates, even the shortest graffiti can provide researchers with important additional information on possible changes in the ancient climate and landscape.

And Function

The review article discusses the possibilities of using fractal mathematical analysis to solve scientific and applied problems of modern biology and medicine. The authors show that only such an approach, related to the section of nonlinear mechanics, allows quantifying the chaotic component of the structure and function of living systems, that is a priori important additional information and expands, in particular, the possibilities of diagnostics, differential diagnosis and prediction of the course of physiological and pathological processes. A number of examples demonstrate the specific advantages of using fractal analysis for these purposes. The conclusion can be made that the expanded use of fractal analysis methods in the research work of medical and biological specialists is promising.

‘Time’, wrote Sir Thomas Browne, ‘which antiquates antiquities, and hath an art to make dust of all things, hath yet spared these minor monuments’. The Nile Valley is full of major monuments—pyramids, tombs and temples; each expedition which goes into the Libyan Desert learns that it is well-filled with minor ones and remarkable among these are paintings and gravings on rocks.

This study investigated the relevance of an occupational assessment, based on the model of human occupation, with elderly patients on rehabilitation wards. The assessment was implemented and evaluated on a three-part questionnaire administered by occupational therapists. The assessment showed some importance when establishing the needs of and planning treatment for this patient group. In particular, it collected important additional information about the patients' values and attitudes. The model was shown to be of particular benefit in one hospital and more relevant to patients expected to require longer-term treatment and those who had had a stroke.

Glucosinolate extracts from sprouts of common Brassica nigra, B. juncea cv. Scala, B. carinata cv. Eleven, and Sinapis alba cv. Ludique were analysed by reversed phase high-performance liquid chromatography-diode array detection-mass spectrometry. The effect of the glucosinolate–myrosinase system on in vitro mycelial growth of Phytophthora cinnamomi Rands and Pythium spiculum B. Paul was assessed. Likewise, sinigrin and sinalbin monohydrate commercial standards were also tested. The extracts from B. carinata, which contained 159 mmol/g plant DW equivalent (85% sinigrin, 5% gluconapin, and 3% glucotropaeolin), were the most effective against Phytophthora and Pythium isolates used in this study. However, the extract from S. alba, which contained 1 180 mmol/g (100% sinalbin), did not inhibit the mycelial growth of the isolates tested. The use of the glucosinolate-myrosinase system provides important additional information to advance in the implementation of field application of brassicaceous amendments for the control of soil-borne pathogens.

Electroencephalogram Eeg

For presurgical assessments for resection of an epileptogenic lesion or zone, evaluations over the last 20 years have established magnetoencephalography (MEG) as a valuable tool in routine clinical practice in both adult and paediatric age groups. MEG can accurately localize both ictal and inter-ictal spike sources. MEG yields important additional information in around 30% of patients with epilepsy of suspected neocortical origin, aiding in the modification or extension of invasive measurements. Seizure freedom is most likely to occur when there is concordance between electroencephalogram (EEG) and MEG localization, and least likely to occur when these results are divergent. In some patients, invasive recordings may not be viable or repeatable. In these cases, MEG localization frequently provides additional information for planning surgery. Recent developments in technology for movement compensation and enhanced noise reduction provide optimism for continually improving outcomes of MEG-enhanced presurgical evaluations.

AbstractIn the current coronavirus SARS-CoV-2 pandemic, certain patients are becoming seriously ill. Lung pathologies are common, and some patients even go on to develop acute respiratory distress syndrome (ARDS), which requires intubation and artificial respiration of the critically ill patient. Imaging of the lung is absolutely necessary to obtain a diagnosis, assess the course of disease and for treatment. Particularly in gynecology and obstetrics (OBGYN), ultrasound scans of the lung can be a useful additional tool when caring for pregnant patients in the delivery room. As obstetricians use ultrasound imaging a lot in routine clinical practice, in the current pandemic setting, routine prenatal imaging screening could be expanded by the addition of ultrasound scans of the lung. Lung sonography can offer important additional information, particularly in obstetrics where the indications for radiation-emitting imaging are particularly restrictive. If there is a sonographic suspicion of lung involvement, then, depending on the symptoms and the morphological extent of the ultrasound findings, it may be necessary to consider admitting the patient to hospital for close fetal and maternal monitoring.

The two volumes of rock-drawings from southern Upper Egypt collected by Dr H. A. Winkler, and published by the Egypt Exploration Society, together form a work of the utmost interest and importance to all interested in the archaeology and ethnology of North Africa. In the first volume, published in 1938, Dr Winkler included a selection of the material collected from the deserts east of the Nile and from the Nile valley itself. In the second volume, just published, the drawings and paintings are all from the deserts west of the Nile and cover three main regions : first the edges of the Nile valley itself from Qena to Aswan ; secondly the regions between the Nile and Kharga; and thirdly certain parts of the central Libyan Desert towards the extreme south-western frontiers of Egypt, in particular the mountain ‘ desert oasis ’ of Gebel ’Uweinat.

Abstract Background : The Covid 19 pandemic introduced the need to outline new guidelines for the treatment of the Covid positive patient in surgery. With this report we present what we believe to be important additional information about an area that has not yet been studied, the potential infectivity of peritoneal secretions.Case presentation : A 73-year-old woman accesses our PS where she is found to be positive on the nosepharyngeal swab for Covid 19. The patient presents a picture of intestinal occlusion from imprisoned hernia, which is why she undergoes exploratory laparotomy surgery. During surgery a peritoneal swab is performed which is positive for Covid 19.Conclusion : This case suggests that, in the presence of patients susceptible to surgical therapy with negative Covid swab, performing a peritoneal swab may reveal a false negative. An extensive database that collects the results of pharyngeal and peritoneal swabs of patients undergoing surgery is necessary to delineate the appropriate approach to the patient in the Covid era.

Introduction Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the etiological agent of coronavirus disease (COVID-19). People infected with SARS-CoV-2 may exhibit no or mild non-specific symptoms; thus, they may contribute to silent circulation of the virus among humans. Since SARS-CoV-2 RNA can be detected in stool samples, monitoring SARS-CoV-2 RNA in waste water (WW) has been proposed as a complementary tool to investigate virus circulation in human populations. Aim To test if the quantification of SARS-CoV-2 genomes in WW correlates with the number of symptomatic or non-symptomatic carriers. Method We performed a time-course quantitative analysis of SARS-CoV-2 by RT-qPCR in raw WW samples collected from several major WW treatment plants in Greater Paris. The study period was 5 March to 23 April 2020, including the lockdown period in France (from 17 March). Results We showed that the increase of genome units in raw WW accurately followed the increase of human COVID-19 cases observed at the regional level. Of note, the viral genome could be detected before the epidemic grew massively (around 8 March). Equally importantly, a marked decrease in the quantities of genome units was observed concomitantly with the reduction in the number of new COVID-19 cases, 29 days following the lockdown. Conclusion This work suggests that a quantitative monitoring of SARS-CoV-2 genomes in WW could generate important additional information for improved monitoring of SARS-CoV-2 circulation at local or regional levels and emphasises the role of WW-based epidemiology.

Those who are dedicated to the analysis of structural changes in tissues have tried, over time, to seek increasingly "more rigorous" methods to be able to detach themselves from the merely observational and subjective. That is, leaving aside the semi-quantitative scores based on scores that are given to the lesion in a tissue according to its degree of severity. The argument is that the final injury score will depend more on the subjectivity and experience of the observer. With the advent of digital images and programs for their analysis, the application of numerical methods for estimating changes in tissues was greatly facilitated. With them we do not completely suppress the observational, but, to a large extent and if we are rigorous, we can significantly reduce its influence. Thus, in two-dimensional images, we can make direct measurements such as the diameter and length of a gland, its surface, etc., always in previously calibrated systems. We can also estimate the dimensions of structures that are part of a tissue and the spatial relationships between them based on a two-dimensional image. In this case we will use stereology, which uses simple mathematical formulas, but is very time consuming for analysis. Now, structuralists have realized that the normal components of a tissue or a cell maintain certain spatial relationships and proportionality to each other, which also defines their shapes and textures (complexity), constituting the characteristic histological images of a kidney, liver, uterus, etc. Both the pathology and the functional adaptations alter these normal relationships, which wanted to be estimated through the application of the fractal dimension. The justification is that, when faced with a certain insult or stimulus, the tissue or organ responds “in toto”, not one part yes and another no. The single measurement of diameters, surfaces, etc., while complementary, was always thought to be incomplete because we were missing those changes in the relationships between tissue components or from one cell to another, which provide important additional information.
