Mummy 527 B* belongs to the “Giovanni Marro” Egyptian Collection of the Museum of Anthropology and Ethnography of the University of Turin. This mummy of a oneyear- old pre-dynastic child was found in Gebelein in 1935 in a small necropolis discovered during excavations of the “Missione Archeologica Italiana” led by G. Farina, the new Director of the Egyptian Museum of Turin, with the participation of Prof. G. Marro as anthropologist. A whole body spiral CT scan with thin slices (1,00 mm thickness, 0,5 mm reconstruction interval) was followed by multiplanar and 3D reconstruction. The aim was to evaluate the child’s age at death and the presence of lethal pathologies. This study confirms the fundamental role of non-invasive techniques in the study of such rare pre-dynastic specimens.

What is the relationship between anatomical connection strength and rhythmic synchronization? Simultaneous recordings of 15 cortical areas in two macaque monkeys show that interareal networks are functionally organized in spatially distinct modules with specific synchronization frequencies, i.e. frequency-specific functional connectomes. We relate the functional interactions between 91 area pairs to their anatomical connection strength defined in a separate cohort of twenty six subjects. This reveals that anatomical connection strength predicts rhythmic synchronization and vice-versa, in a manner that is specific for frequency bands and for the feedforward versus feedback direction, even if interareal distances are taken into account. These results further our understanding of structure-function relationships in large-scale networks covering different modality-specific brain regions and provide strong constraints on mechanistic models of brain function. Because this approach can be adapted to non-invasive techniques, it promises to open new perspectives on the functional organization of the human brain.

Temporal artery biopsy is considered the gold standard investigation of giant cell arteritis and is recommended in suspected cases despite a sensitivity of 81–91%. This review highlights the potential risk of facial nerve injury during temporal artery biopsy and introduces recent advances in the emerging role of imaging modalities. When these non-invasive techniques are used in conjunction with American College of Rheumatology scoring, which includes clinical features and biochemical test results, temporal artery biopsy may be avoided in selected cases.

Coenurosis is a fatal disease caused by the larval stage of Taenia multiceps that leads to enormous economic losses in sheep production. Five ewes affected by chronic coenurosis were studied by CT and one of them by MRI. CT allowed detection, localisation and characterisation of the parasitic cyst in all evaluated animals. MRI evinced the white and grey matter damage in the areas adjacent to the coenurus. One of the affected animals recovered spontaneously, showing a shrunken and collapsed parasitic cyst surrounded by partially mineralised tissue in the CT and MRI images. These findings were confirmed at postmortem examination. In conclusion, CT and MRI are valuable non-invasive techniques that allow early diagnosis, characterisation and follow-up of ovine CNS diseases. To the authors’ knowledge, this is the first report of a spontaneous clinical remission of chronic coenurosis in small ruminants.

Inflammation disturbs biochemical pathways involved in homeostasis of the endothelium. Research has established clear links between inflammatory mediators, particularly C-reactive protein and tumour necrosis factor alpha, endothelial dysfunction, and atherosclerosis. Endothelial dysfunction and atherosclerosis may be subclinical at early stages, and thus the ability to detect them with non-invasive techniques is crucially important, particularly in populations at increased risk for cardiovascular disease, such as those with rheumatoid arthritis. This may allow the identification of interventions that may reverse these processes early on. One of the best non-pharmacological interventions that may achieve this is physical activity. This review explores the associations between inflammation, endothelial dysfunction, and atherosclerosis and discusses the role of exercise in blocking specific pathways in the inflammation, endothelial dysfunction - atherosclerosis network.

Many researchers and clinicians have taken the value of hepatic venous pressure gradient (HVPG) as an essential prognostic factor in subjects with chronic liver disorders. And HVPG alterations characterize a predictive value in subjects at the beginning of the disease (HVPG 6 – 10 mmHg) as well as in subjects in whom hemodynamically significant portal hypertension has developed (HVPG ≥ 10 mmHg). Our review aims to present the feasibility and applicability of HVPG in modern clinical practice in patients with liver cirrhosis, including invasive and non-invasive methods. HVPG measurement is a feasible method with a favorable safety profile. However, hemodynamically significant portal hypertension also might be determined using non-invasive options as elastography, magnetic resonance imaging, and indices derived from laboratory parameters, e.g., aspartate aminotransferase-to-platelet ratio, platelet count/spleen diameter ratio, or VITRO score. Hepatic vein catheterization with the evaluation of HVPG is the current gold standard for determining portal pressure; however, new non-invasive techniques are nowadays more frequently used.

Background: Non-invasive techniques such as ultrasound and CT scan (abdomen and pelvis) are widely used in investigations of pancreaticobiliary disease, though easily available and cheap, have limitations in term of sensitivity. Invasive procedures like ERCP, though considered gold standard for diagnosis of pancreaticobiliary disease, requires highly skilled team of supporting doctors. MR Cholangio Pancreatography (MRCP) is evolving as an effective non-invasive imaging technique for examining patients with pancreatic or biliary diseases. The purpose is to illustrate the findings of MRCP in various abnormalities affecting the pancreaticobiliary diseases. Objective was to study the role of MRCP as non-invasive imaging modality for diagnosis of pancreatobiliary diseases, in diagnosing lower biliary tract pathologies, pancreatic duct pathologies, determining treatment modality in pancreatobiliary diseases, surgical or endoscopicMethods: This is a prospective study conducted in Dr. D. Y. Patil Medical College and Hospital, Pimpri, Pune for a period of two years from July 2015 to September 2017. 60 patients were enrolled in the study, their MRCP was performed following ultrasonography.Results: The MRCP diagnosed the following pathologies- cholelithiasis, choledocholithiasis, CBD stricture, chronic pancreatitis, choledochal cyst, cholangiocarcinoma, pseudocyst of pancreas, sclerosing cholangitis and GB perforation. Out of 60, 32 underwent surgical procedure and 20 underwent endoscopic procedure and 8 were treated medically.Conclusions: MRCP is very accurate in diagnosing CBD and pancreatic duct pathologies. Its helps in deciding the treatment modality for the same. It decides whether the patient requires ERCP and thus cuts down the rate of ‘negative’ ERCP.

Many patients are dissatisfied with scars on both visible and non-visible body sites and would value any opportunity to improve or minimise scarring following surgery. Approximately 44 million procedures in the US and 42 million procedures in the EU per annum could benefit from scar reduction therapy. A wide range of non-invasive and invasive techniques have been used in an attempt to improve scarring although robust, prospective clinical trials to support the efficacy of these therapies are lacking. Differences in wound healing and scar outcome between early fetal and adult wounds led to interest in the role of the TGFβfamily of cytokines in scar formation and the identification of TGFβ3 (avotermin) as a potential therapeutic agent for the improvement of scar appearance. Extensive pre-clinical and human Phase I and II clinical trial programmes have confirmed the scar improving efficacy of avotermin which produces macroscopic and histological improvements in scar architecture, with improved restitution of the epidermis and an organisation of dermal extracellular matrix that more closely resembles normal skin. Avotermin is safe and well tolerated and is currently in Phase III of clinical development, with the first study, in patients undergoing scar revision surgery, fully recruited.

The review analyzes the role of chronic inflammatory diseases in the induction of endothelial dysfunction as a factor in the acceleration of atherosclerotic changes in the cardiovascular system. The importance of non-invasive techniques for evaluating endothelial dysfunction to detect preclinical atherosclerotic changes in children and adolescents with rheumatic was discussed. It is postulated that the detection of early signs of endothelial dysfunction in children and adolescents with rheumatic diseases, along with traditional risk factors, should become an integral part of the strategy for preventing adverse cardiovascular events in subsequent age periods.

During their evolutionary history, plants have evolved the ability to synthesize and accumulate small molecules known as secondary metabolites. These compounds are not essential in the primary cell functions but play a significant role in the plants’ adaptation to environmental changes and in overcoming stress. Their high concentrations may contribute to the resistance of the plants to the bacterium Xylella fastidiosa, which has recently re-emerged as a plant pathogen of global importance. Although it is established in several areas globally and is considered one of the most dangerous plant pathogens, no cure has been developed due to the lack of effective bactericides and the difficulties in accessing the xylem vessels where the pathogen grows and produces cell aggregates and biofilm. This review highlights the role of secondary metabolites in the defense of the main economic hosts of X. fastidiosa and identifies how knowledge about biosynthetic pathways could improve our understanding of disease resistance. In addition, current developments in non-invasive techniques and strategies of combining molecular and physiological techniques are examined, in an attempt to identify new metabolic engineering options for plant defense.
