Does hyperspectral always matter? A critical assessment of near infrared versus hyperspectral near infrared in the study of heterogeneous samples.

Near Infrared spectroscopy (NIR), in combination with Chemometrics, has been used for many years in diverse scenarios, mostly focused on the classification and quantitation of properties in food, pharmaceutical preparations, artwork material, etc. This success has been possible due to their desirable properties: fast, reliable (under certain conditions), non-destructive, easy to implement from a hardware perspective, and able to create robust and transferable multivariate models. For some years now, another modality has been gaining the attention of NIR users, especially in the Food sector.

Distal outpatients hemodynamic treatment of chronic venous insufficiency of the lower limbs: a new proposal.

The etiology of the venous insufficiency of the lower limbs is related to the increase of the district pressure. This occurs in case of pressure overload of the afferent compartment with a progressive increase of the gradient until the reversal of the flow direction. Varicose veins would be the effect and not the cause of the pressure overload which must always be researched in the efferent (draining) compartment.

A Feasibility Study towards the On-Line Quality Assessment of Pesto Sauce Production by NIR and Chemometrics.

The food industry needs tools to improve the efficiency of their production processes by minimizing waste, detecting timely potential process issues, as well as reducing the efforts and workforce devoted to laboratory analysis while, at the same time, maintaining high-quality standards of products. This can be achieved by developing on-line monitoring systems and models. The present work presents a feasibility study toward establishing the on-line monitoring of a pesto sauce production process by means of NIR spectroscopy and chemometric tools.

How Chemometrics Can Fight Milk Adulteration.

Adulteration and fraud are amongst the wrong practices followed nowadays due to the attitude of some people to gain more money or their tendency to mislead consumers. Obviously, the industry follows stringent controls and methodologies in order to protect consumers as well as the origin of the food products, and investment in these technologies is highly critical. In this context, chemometric techniques proved to be very efficient in detecting and even quantifying the number of substances used as adulterants.

Characterization of Basil Volatile Fraction and Study of Its Agronomic Variation by ASCA.

Basil is a plant known worldwide for its culinary and health attributes. It counts more than a hundred and fifty species and many more chemo-types due to its easy cross-breeds. Each species and each chemo-type have a typical aroma pattern and selecting the proper one is crucial for the food industry.

Echocolor Doppler morpho-functional study of the jugulo-subclavian confluence in chronic cerebro-spinal venous insufficiency and multiple sclerosis patients.

Objectives: The aim of this work is to measure the mean diameter of the confluence jugulo- subclavian, the impact of different types of jugular confluences and the correlation between the types of confluences and the Valsalva maneuver (jugular reflux) in subjects with Chronic Cerebro-Spinal Venous Insufficiency (CCSVI) and Multiple Sclerosis.

Method: We investigated by Echo-Color-Doppler (ECD) 103 subjects (67 F 36M) of mean age 45 ± 12 years (a minimum of 22 to a maximum of 79 years, with a median of 44 and a modal value 42 years), mean EDSS of 4.7 and average disease duration of 12 years.

LC-HRMS for Characterizing Durum Wheat Pasta Production Variability and Consumer Overall Liking.

Semolina pasta represents one of the most important dishes in Italian cuisine worldwide. Italy is the leader in its production and, recently, the worldwide diffusion of its production has begun to grow tremendously. The perceived quality of a food product, such as pasta, is a key feature that allows a company to increase and maintain the competitive advantage of a specific brand.

Venous compression syndrome of internal jugular veins prevalence in patients with multiple sclerosis and chronic cerebro-spinal venous insufficiency.

Objectives: Analysis of the incidence of Venous Compression Syndrome (VCS) with full block of the flow of the internal jugular veins (IJVs) in patients with Multiple Sclerosis and Chronic cerebro-spinal venous insufficiency.

Methods: We included 769 patients with MS and CCSVI (299 males, 470 females) and 210 controls without ms and ccsvi (92 males, 118 females). each subject was investigated by echo-color-doppler (ecd).

Risk of jugular compression blocks in workers exposed to prolonged upright posture.

Background: The working posture affects the peripheral venous circulation, although the current literature does not report any correlation between working posture and the abnormalities of the jugular veins flow. The purpose of this preliminary research is to study, in female workers, the prevalence of Venous Compressive Syndrome (VCS) caused by total block of the internal jugular veins flow, so-called "White Compression". Due to complete compression by postural, muscular, fascial, anatomical or bone anomalies, White Compression is not visible by EchoColorDoppler (ECD) and its flow can only be detected by the rotational movements of the head or by Valsalva's maneuver.

Jugular diameter and venous reflux.

Objectives: Aims of this study were to investigate the prevalence of reflux on internal jugular veins(IJV) by Valsalva maneuver and to define the association between reflux of IJV in subjects with both CCSVI and MS.

Methods: We recruited 393 patients with MS and CCSVI. Study participants underwent EchoColor Doppler exam in order to define IJV diameter at confluence in subclavian (JSd).

Co-located haptic interaction for virtual USG exploration.

Ultrasonography is a widespread diagnostic technique that can take advantage of virtual reality for the purpose of training and rehearsal. The placement, orientation and body interaction of the probe is fundamental for the execution of the exploration. This paper introduces a virtual reality setup that employs visuo-haptic feedback for virtual ultrasonography.

Effect of water and gluten on physico-chemical properties and stability of ready to eat shelf-stable pasta.

A multi-analytical and multi-dimensional approach was used to investigate the effect of moisture and gluten on physico-chemical properties of shelf-stable ready to eat (RTE) pasta. Moisture and frozen water contents were not affected by formulation nor storage time. Hardness and retrograded amylopectin significantly increased during storage in all samples, more markedly in pasta with the lowest moisture content.

C1-C2 X-Ray assessment of misalignment parameters in patients with Chronic Cerebra-spinal Venous Insufficiency and Multiple Sclerosis versus patients with other pathologies.

Purpose: The complete compression of the internal jugular veins, in front position, shows a prevalence of 48% and it is equally distributed in the various segments of these veins in patients with Chronic Cerebro-Spinal Venous Insufficiency (CCSVI) and Multiple Sclerosis (MS). The aim of this search is to identify radiological dislocation of C1-C2 as specific markers in patients with CCSVI and Multiple Sclerosis (MS).

Method: We investigated 386 patients suffering from CCSVI and Multiple Sclerosis and a control group of 156 patients without MS.

New acoustic wave therapy improves quality of life in patients with multiple sclerosis and chronic cerebrospinal venous insufficiency.

A Multiple Sclerosis patient with chronic cerebrospinal venous insufficiency (CCSVI) treated by acoustic waves, modulated in frequency and power of the Dreno-MAM® device, showed a progressive improvement in motor coordination, resistance to work, muscular power and rigidity, and distal microcirculation. Life quality, chronic fatigue, and clinical severity questionnaires EDSS show marked improvements with a follow-up of two years. We suggest that the method could be also used in the chronic fatigue syndrome and other neurological diseases such as Parkinson or Meniere syndrome.
