Surgical pathology and the diagnosis of invasive visceral yeast infection: two case reports and literature review
2013
Invasive mycoses are life-threatening opportunistic infections that have recently emerged as a cause of morbidity and mortality following general and gastrointestinal surgery. Candida species are the main fungal strains of gut flora. Gastrointestinal tract surgery might lead to mucosal disruption and cause Candida spp. to disseminate in the bloodstream. Here we report and discuss the peculiar clinical and morphological presentation of two cases of gastrointestinal Candida albicans lesions in patients who underwent abdominal surgery. Although in the majority of cases reported in the literature, diagnosis was made on the basis of microbiological criteria, we suggest that morphological feature…
A body weight loss- and health-promoting gut microbiota is established after bariatric surgery in individuals with severe obesity
2020
Obesity has reached an epidemic level worldwide, and bariatric surgery (BS) has been proven to be the most efficient therapy to reduce severe obesity-related comorbidities. Given that the gut microbiota plays a causal role in obesity development and that surgery may alter the gut environment, investigating the impact of BS on the microbiota in the context of severe obesity is important. Although, alterations at the level of total gut bacteria, total gene content and total metabolite content have started to be disentangled, a clear deficit exists regarding the analysis of the active fraction of the microbiota, which is the fraction that is most reactive to the BS. Here, active gut microbiota…
Analysis of gut microbiota in advanced non-small cell lung cancer (NSCLC) patients treated with immune-checkpoints blockers
2019
Abstract Background The microbiota community is considered as an organ of the human body. Recent studies have found that dysbiosis may have an impact on the interaction between immune regulation and tumor treatment. The main objective of this study is to characterize the gut microbiota in patients with non-small cell lung cancer (NSCLC) in advanced stages, and its relationship with obesity, smoking habits, clinical pathological features and response to treatment with immune-checkpoints blockers (ICB). Methods 16S rRNA gene sequencing was performed on 48 stool samples from advanced NSCLC patients prior to treatment with ICB (PD-1 inhibitor and PD-L1 inhibitor). The database used for the taxo…
A new species within the Centaurea busambarensis complex (Asteraceae, Cardueae) from Sicily
2022
The Centaurea busambarensis group is made up by eight species endemic to Sicily. We statistically evaluated a population found on the Nebrodi Mountain (NE Sicily) to verify if the observed morphological differences with the already known taxa justified the description of a new one. It resulted in being sufficiently distinct to deserve recognition at the species level. Centaurea valdemonensis, a new species endemic to Sicily is described and illustrated here. It is confined to the Nebrodi Mountains (NE Sicily). The distinction of this taxon from the others belonging to the C. busambarensis complex has been supported with the aid of statistical analyses on morphological characters. The differ…
The role of in situ species diversification for the evolution of high vascular plant species diversity in the European Alps—A review and interpretati…
2017
Abstract By harbouring ca. 3500 native vascular plant species in an area of ca. 170 000 km2, the European Alps represent a region of very high species diversity. Using the most recently published flora of the area and phylogenetic literature, I here review which proportion of the endemic flora of the Alps is the result of in situ diversification, i.e., of diversification in the area and (largely) restricted to the area. There exist only very few and mostly species-poor species diversifications in the Alps, accounting for ca. 1.2% of the native and for ca. 9% of the endemic flora of the Alps. In contrast to this, ca. 33% of the endemic species of the Alps belong to lineages widespread in the…
Sociālie tīkli kā mārketinga platforma - Latvijas mazo maiznīcu gadījuma analīze
2020
Bakalaura darba tēma ir “Sociālie tīkli kā mārketinga platforma - Latvijas mazo maiznīcu gadījuma analīze”. Sociālo mediju nozīme cilvēku ikdienas dzīvē ar katru brīdi pieaug ar vien vairāk. Uzņēmumi un zīmoli šo situāciju izmanto savā labā jau vairākus gadus, kas ir par pamatu tam, ka ir izveidojusies atsevišķa mārketinga sfēra – sociālo mediju mārketings. Mārketinga speciālisti pauž dažādus viedokļus par to, vai sociālo mediju mārketings tiks izmantots kā ilgtspējīga mārketinga plāna sastāvdaļa, vai tomēr šis mārketinga paveids ir mirkļa tendence, kas pazudīs pēc kāda laika. Darba mērķis ir apskatīt Latvijas mazo maiznīcu radīto saturu “Facebook” vidē, kā arī noskaidrot mērķauditorijas vi…
Chemical Ecology of Floral Resources in Conservation Biological Control.
2023
Conservation biological control aims to enhance populations of natural enemies of insect pests in crop habitats, typically by intentional provision of flowering plants as food resources. Ideally, these flowering plants should be inherently attractive to natural enemies to ensure that they are frequently visited. We review the chemical ecology of floral resources in a conservation biological control context, with a focus on insect parasitoids. We highlight the role of floral volatiles as semiochemicals that attract parasitoids to the food resources. The discovery that nectar-inhabiting microbes can be hidden players in mediating parasitoid responses to flowering plants has highlighted the co…

New developments in the pathogenesis of obesity-induced hypertension
2015
Obesity is a disorder that develops from the interaction between genotype and environment involving social, behavioral, cultural, and physiological factors. Obesity increases the risk for type 2 diabetes mellitus, hypertension, cardiovascular disease, cancer, musculoskeletal disorders, chronic kidney and pulmonary disease. Although obesity is clearly associated with an increased prevalence of hypertension, many obese individuals may not develop hypertension. Protecting factors may exist and it is important to understand why obesity is not always related to hypertension. The aim of this review is to highlight the knowledge gap for the association between obesity, hypertension, and potential …
Principi di spontaneizzazione in Sicilia di Aesculus hippocastanum (Hippocastanaceae)
2009
The first record of Aesculus hippocastanum naturalized in Sicily is presented from a locality near the Alcantara river (Floresta, Messina) in the montane belt where decidous Turkey oak and chestnut woods are found. This species is not frequently cultivated in Sicily. In that locality several mature individuals likely introduced several decades ago occur.
