Genetic Evidence of the Black Death in the Abbey of San Leonardo (Apulia Region, Italy): Tracing the Cause of Death in Two Individuals Buried with Co…

2021

The Abbey of San Leonardo in Siponto (Apulia, Southern Italy) was an important religious and medical center during the Middle Ages. It was a crossroads for pilgrims heading along the Via Francigena to the Sanctuary of Monte Sant’Angelo and for merchants passing through the harbor of Manfredonia. A recent excavation of Soprintendenza Archeologica della Puglia investigated a portion of the related cemetery, confirming its chronology to be between the end of the 13th and beginning of the 14th century. Two single graves preserved individuals accompanied by numerous coins dating back to the 14th century, hidden in clothes and in a bag tied to the waist. The human remains of the individuals were …

Acute Parvovirus B19 Infection and Anemia duringPlasmodium falciparumMalaria

[NO TITLE AVAILABLE]

2014

Malaria is still a primary health problem in Colombia. The locality of Tierradentro is situated in the municipality of Montelibano, Cordoba, in the northwest of Colombia, and has one of the highest annual parasite index of malaria nationwide. However, the vectors involved in malaria transmission in this locality have not yet been identified. In this study, the local anthropophilic Anopheles composition and natural infectivity with Plasmodium were investigated. In August 2009, 927 female Anopheles mosquitoes were collected in eight localities using the human landing catch method and identified based on their morphology. Cryptic species were determined by restriction fragment length polymorph…

Biological Profiling of Semisynthetic C19-Functionalized Ferruginol and Sugiol Analogues

2021

[EN] The abietane-type diterpenoids are significant bioactive compounds exhibiting a varied range of pharmacological properties. In this study, the first synthesis and biological investigation of the new abietane-diterpenoid (+)-4-epi-liquiditerpenoid acid (8a) together with several of its analogs are reported. The compounds were generated from the readily available methyl callitrisate (7), which was obtained from callitrisic acid present in Moroccan Sandarac resin. A biological evaluation was conducted to determine the effects of the different functional groups present in these molecules, providing basic structure-activity relationship (SAR) elements. In particular, the ferruginol and sugi…

Microbiota Variation Across Life Stages of European Field-Caught Anopheles atroparvus and During Laboratory Colonization: New Insights for Malaria Re…

2021

The potential use of bacteria for developing novel vector control approaches has awakened new interests in the study of the microbiota associated with vector species. To set a baseline for future malaria research, a high-throughput sequencing of the bacterial 16S ribosomal gene V3-V4 region was used to profile the microbiota associated with late-instar larvae, newly emerged females, and wild-caught females of a sylvan Anopheles atroparvus population from a former malaria transmission area of Spain. Field-acquired microbiota was then assessed in non-blood-fed laboratory-reared females from the second, sixth, and 10th generations. Diversity analyses revealed that bacterial communities varied …

Health literacy and Infectious Diseases : Why does it matter?

2016

Objectives: Multifactorial interventions are crucial to arrest the threat posed by infectious diseases. Public involvement requires adequate information, but determinants such as health literacy can impact on the effective use of such knowledge. The influence of health literacy on infectious diseases is examined in this paper. Methods: Databases were searched from January 1999 through July 2015 seeking studies reporting on health literacy and infections such tuberculosis, malaria, and influenza, and infection-related behaviours such as vaccination and hand hygiene. HIV was excluded, as comprehensive reviews have already been published. Results: Studies were found on antibiotic knowledge and…

Toward fast malaria detection by secondary speckle sensing microscopy

2012

Diagnosis of malaria must be rapid, accurate, simple to use, portable and low cost, as suggested by the World Health Organization (WHO). Despite recent efforts, the gold standard remains the light microscopy of a stained blood film. This method can detect low parasitemia and identify different species of Plasmodium. However, it is time consuming, it requires well trained microscopist and good instrumentation to minimize misinterpretation, thus the costs are considerable. Moreover, the equipment cannot be easily transported and installed. In this paper we propose a new technique named "secondary speckle sensing microscopy" ((SM)-M-3) based upon extraction of correlation based statistics of s…

Novel image processing approach to detect malaria

2015

In this paper we present a novel image processing algorithm providing good preliminary capabilities for in vitro detection of malaria. The proposed concept is based upon analysis of the temporal variation of each pixel. Changes in dark pixels mean that inter cellular activity happened, indicating the presence of the malaria parasite inside the cell. Preliminary experimental results involving analysis of red blood cells being either healthy or infected with malaria parasites, validated the potential benefit of the proposed numerical approach.

Il servizio della Croce Rossa Italiana nelle zolfare di Sicilia dal 1898 al 1913.

2008

La Croce Rossa Italiana nelle miniere di zolfo in Sicilia ha iniziato a svolgere il suo primo servizio in tempo di pace nel 1898, a 34 anni dalla sua fondazione. E' stata ammirevole l'attività di I. Di Giovanni e di altri medici, anche dell'Università degli Studi di Palermo, quali A. Trmbusti ed i suoi allievi A. Amato e G. Gabrielli. Il servizio ha interessato all'esordio gli infortuni sul lavoro e successivamente anche la lotta all'anchilostomiasi e alla malari. Le norme hanno imposto agli industriali lo sviluppo di un sistema di tutela assicurativa e la costituzione in sindacato, al pari di altre nazioni europee. la presenza della Croce Rossa si è protratta fino al 1913, quando il Sindac…
