Molecular cloning, promoter analysis and SNP identification of Italian Nicastrese and Saanen lactoferrin gene
Lactoferrin (Lf) is an iron-binding glycoprotein found in exocrine secretions including milk. High levels of lactoferrin may have a role in the prevention of microbial infection of the mammary gland. In this report we sequenced and characterized goat lactoferrin cDNA and its promoter region in two different breeds of goat. The complete cDNA comprised 2356 nucleotides, including 38bp at the 5'-UTR and 194bp at the 3'-UTR. The open reading frame is 2127bp long and it encodes a mature protein of 689 aminoacids. A total of 19 nucleotide differences, 11 of them being responsible for 8 aminoacid changes, were identified through the comparison with French, Korean and Tibetan goat lactoferrin cDNAs. About 1700bp of the lactoferrin gene promoter were sequenced. Sequence analysis revealed a non-canonical TATA box, multiple SP1/GC elements, and other putative binding sites for transcription factors, such as NF-kappaB, STAT3 and AP2. Two SNPs were identified, one of which would seem to create a new putative AP2 consensus sequence. The presence of an additional AP2 binding site could be associated with quantitative differences of such protein fraction, which could enhance all the activities related to such protein, and improve mammary gland defence against bacterial infections
Electronic Instability in a Zero-Gap Semiconductor: The Charge-DensityWave in (TaSe4)(2)I
We report a comprehensive study of the paradigmatic quasi-1D compound (TaSe4)(2)I performed by means of angle-resolved photoemission spectroscopy (ARPES) and first-principles electronic structure calculations. We find it to be a zero-gap semiconductor in the nondistorted structure, with non-negligible interchain coupling. Theory and experiment support a Peierls-like scenario for the charge-density wave formation below T-CDW = 263 K, where the incommensurability is a direct consequence of the finite interchain coupling. The formation of small polarons, strongly suggested by the ARPES data, explains the puzzling semiconductor-to-semiconductor transition observed in transport at T-CDW.open114sciescopu
The assessment of vertebral fractures in elderly women with recent hip fractures: the BREAK Study
Summary This study aimed to evaluate the prevalence of
vertebral fractures in elderly women with a recent hip fracture.
The burden of vertebral fractures expressed by the Spinal
Deformity Index (SDI) is more strictly associated with the
trochanteric than the cervical localization of hip fracture and
may influence short-term functional outcomes.
Introduction This study aimed to determine the prevalence
and severity of vertebral fractures in elderly women with
recent hip fracture and to assess whether the burden of vertebral
fractures may be differently associated with trochanteric
hip fractures with respect to cervical hip fractures.
Methods We studied 689 Italian women aged 60 years or
over with a recent low trauma hip fracture and for whom an
adequate X-ray evaluation of spine was available. All radiographs
were examined centrally for the presence of any
vertebral deformities and radiological morphometry was
performed. The SDI, which integrates both the number and
the severity of fractures, was also calculated.
Results Prevalent vertebral fractures were present in 55.7 % of
subjects and 95 women (13.7 %) had at least one severe
fracture. The women with trochanteric hip fracture showed
higher SDI and higher prevalence of diabetes with respect to
those with cervical hip fracture, p00.017 and p00.001, respectively.
SDI, surgical menopause, family history of fragility
fracture, and type2 diabetes mellitus were independently associated
with the risk of trochanteric hip fracture. Moreover, a
higher SDI was associated with a higher percentage of postsurgery
complications (p00.05) and slower recovery (p<0.05).
Conclusions Our study suggests that the burden of prevalent
vertebral fractures is more strictly associated with the
trochanteric than the cervical localisation of hip fracture and
that elevated values of SDI negatively influence short term
functional outcomes in women with hip fracture
AI Meets Tradition: Enhancing Italian Small Ruminant Biodiversity through Breed Identification
The conservation and sustainable management of Italian small ruminant breeds are crucial for preserving livestock
biodiversity. Italy counts over 100 sheep and goat breeds, often raised in extensive farming systems and
mountainous and marginal areas, many of which hold high cultural and environmental value. Their presence supports
rural economies and contributes to the identity and landscape of regions with strong tourist appeal. However,
many local breeds are at risk due to limited distribution and declining populations. One key challenge in their
management is the correct registration of an animal to a breed, traditionally based on expert morphological evaluation
and assessment of standard adherence. Artificial intelligence (AI), particularly deep learning techniques, offers
innovative solutions to support this sector. A promising application, explored in few studies with encouraging
results, is the development of AI-powered image-based classification tools for breed identification. Extending this
approach to a broader scale could have significant practical implications. With photographic data collected under
diverse conditions and image augmentation techniques, it becomes possible to build a robust and efficient system
adaptable to the morphological variability of local breeds. Also, georeferencing images might be especially valuable,
as many populations are strongly localized in specific regions; spatial data could thus enhance breed recognition,
even in cases of high phenotypic variability or morphological similarity between breeds. A possible outcome
of this approach could be a user-friendly mobile application to assist breeders, technicians, and associations in
breed identification and registration, streamlining procedures and minimizing animal handling. Additionally, such
a tool could serve an educational purpose, providing users—including tourists and local communities—with information
about each breed’s history, risk status, and typical products. By raising public awareness and fostering
a connection between people and livestock biodiversity, this AI-based solution may contribute to the conservation
and valorization of Italy’s small ruminant heritage, while supporting the resilience of rural areas
PREVALENCE OF 'BORDERLINE' VALUES OF CARDIOVASCULAR RISK FACTORS IN THE CLINICAL PRACTICE OF GENERAL MEDICINE IN ITALY: RESULTS OF THE BORDERLINE STUDY.
INTRODUCTION:
The prevalence of patients with 'borderline' levels of cardiovascular risk factors has been rarely investigated, being often reported in studies evaluating abnormal values of these parameters. The BORDERLINE study represents a pilot experience to primarily identify the prevalence of 'high-normal' conditions, such as pre-hypertension, lipid and glucose levels in the upper range of normality in the setting of general practice in Italy.
AIM:
The aim of this study was to evaluate the prevalence of patients with 'borderline' values of cardiovascular risk factors in Italy.
METHODS:
Involved physicians were asked to evaluate the first 20 outpatients, consecutively seen in June 2009. Data were collected in a study-designed case-report form, in which physicians identified thresholds rather than reported absolute values of several clinical parameters. High-normal values were defined as follows: blood pressure (BP) 130-140/85-90 mmHg; total cholesterol 180-200 mg/dL; low-density lipoprotein cholesterol (LDL-C) 130-150 mg/dL; high-density lipoprotein cholesterol (HDL-C) 30-40 mg/dL in males and 40-50 mg/dL in females; triglycerides 130-150 mg/dL and fasting glucose 100-110 mg/dL.
RESULTS:
Fifty-three Italian physicians provided valuable clinical data on 826 individual outpatients, among which 692 (83.7%, 377 women, mean age 60.9 ± 13.2 years, body mass index 26.6 ± 5.0 kg/m2) were included in the present analysis. Prevalence of borderline values of systolic BP and total cholesterol levels were at least comparable with those in the normal limits of the corresponding parameters, whereas prevalence of borderline diastolic BP, LDL-C, HDL-C, triglycerides and fasting glucose levels was significantly lower than that of normal values, but higher than that of abnormal values of the corresponding parameters.
CONCLUSIONS:
Using this sample of healthy subjects in the setting of general practice in Italy, our results demonstrated a relatively high prevalence of borderline values of cardiovascular risk factors, which was at least comparable with that of normal, but significantly higher than that of abnormal thresholds. These preliminary findings may prompt more extensive investigations in the area of 'borderline' cardiovascular risk. This information may, in fact, potentially enable the design of more effective prevention strategies in the future to limit the burden of cardiovascular disease in the general population in Italy
Sustainability challenges in the Italian pet sector
Italy is home to 8.8 million dogs and 10 million cats, with an additional 1-2 million stray dogs and 2.5 million
stray cats. Despite only 15% of dogs and < 1% of cats have a registered pedigree, the purebred animal market
valued at €165-350 million per year. The Italian pet food industry generates €3 billion annually, selling 673,000
tons of pet food. Beyond food, Italians spend €100 million/year on cat litter and €85 million on accessories. A
rough estimate for the impact of pet food sector alone is 1.4-3.8 Mt CO2eq, accounting for 5-12% of agricultural
emissions. It consumes 0.13-0.28 km3 of freshwater, equal to 0.8-1.7% of agricultural water use, while occupying
6-9% (1-1.5MHa) of Italy’s total agricultural area. Our pilot survey describes 60 Italian dogs and 56 Italian cats.
Among dogs, 45% were purebred, including 15% with unregistered pedigrees, while 86% of cats were mixedbreed.
Regarding diet, 73% of cat owners provided both dry and wet food, primarily poultry and fish-based, while
65% of dog owners fed only dry food, with ruminant proteins (beef, lamb) as the most common, followed by
poultry and fish. Monthly food expenses ranged from €13-58 per cat and €35-60 per dog. Litter usage for cats
varied between 4-10 kg per month, costing €5-19, but only 23% of owners purchasing litter chose biodegradable
materials. Annual veterinary and medication costs ranged from €64-170 for cats and €160-400 for dogs. Additional
costs included pet sitters, boarding, accessories, grooming, training, and insurance. These findings highlight
economic and environmental challenges in pet ownership. Sustainable pet care requires multidisciplinary expertise,
genetic management, and alternative proteins to reduce the pet food carbon footprint. Life Cycle Assessment
should be applied across the supply chain, with environmental certification on packaging to promote sustainable
choices. Italy should foster scientific innovation while ensuring environmental responsibility and ethical animal
care. The future challenge is sustainable breeding and management of pets, safeguarding biodiversity and animal
welfare within a One Health approach
BOVITA: a first overview on genome-wide genetic diversity of Italian autochthonous cattle breeds
Analysis of genomic data is increasingly becoming part of the livestock industry and is an invaluable resource for effective management of breeding programs in small populations. The recent availability of genome-wide SNP panels allows providing background information concerning genome structure in domestic animals, opening new perspectives to livestock genetics. BOVITA was established to join local efforts and resources for the genomic characterization of Italian local cattle breeds. Despite the growing diffusion of some cosmopolite specialized breeds, several autochthonous breeds are still bred in Italy. The main aim of the BOVITA is to investigate the genomic structure of Italian local cattle breeds, to provide information on their genetic status that will be useful for the management of the genetic variability, as a contribution to biodiversity conservation and prioritization actions.
A total of about 800 animals (20-32 per breed) belonging to thirty Italian cattle breeds (Agerolese, Bar\ue0-Pustertaler, Burlina, Cabannina, Calvana, Chianina, Cinisara, Garfagnina, Italian Brown, Italian Holstein, Italian Simmental, Marchigiana, Maremmana, Modenese, Modicana, Mucca Pisana, Pezzata Rossa d\u2019Oropa, Piedmontese, Pinzgau, Podolica, Pontremolese, Pustertaler, Reggiana, Rendena, Romagnola, Rossa Siciliana, Sarda, Sardo-Bruna, Sardo-Modicana and Ottonese-Varzese) and two cosmopolitan breeds (Charolaise and Limousine) genotyped with the Illumina BovineSNP50 v2 BeadChip array were collected for the analysis. The genotypes of several breeds were detected in the frame of the project, whereas for some breeds these data are derived by previous studies. The dataset will be analyzed to: study several aspects of population genetic diversity, multi-dimensional scaling plot, population structure, linkage disequilibrium, and runs of homozygosity. In addition, comparative analysis of conserved haplotypes will be conducted to identify genomic segments under selection pressure. Such information also provides important insights into the mechanisms of evolution and is useful for the annotation of significant functional genomics regions. Data analysis will also be useful to select SNPs suitable for parentage test and breed genetic traceability. The analysis of the data will pinpoint the genetic distinctiveness of Italian breeds. Moreover, the obtained results contribute to a better characterization of history and genetic structure of Italian cattle breeds
Genetic and phenotypic characterization of African goat populations to prioritize conservation and production efforts for small-holder farmers in sub-Saharan Africa
Food production systems in Africa depend heavily on the use of locally adapted animals. Goats are critical to small-holder farmers being easier to acquire, maintain, and act as scavengers in sparse pasture. Indigenous goats have undergone generations of adaptation and genetic isolation that have led to great phenotypic variation. These indigenous goats serve as a genetic reservoir for the identification of genes important to environmental adaptation, disease resistance, and improved productivity under local conditions. The immediate goal is to characterize African goat populations to prioritize conservation and production efforts and to develop genomic tools for use in selective breeding programs. We have established a standardized phenotypic scoring system to characterize goats including geographical information data, body measurements, photo characterization, and DNA. To date, 2,443 goats from 12 countries, representing 46 breeds have been sampled. Using the 50K goat beadchip, we report parameters of population structure of 620 African goats
Ezrin interacts with the SARS coronavirus spike protein and restrains infection at the entry stage
© 2012 Millet et al. This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.Background: Entry of Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) and its envelope fusion with host cell membrane are controlled by a series of complex molecular mechanisms, largely dependent on the viral envelope glycoprotein Spike (S). There are still many unknowns on the implication of cellular factors that regulate the entry process. Methodology/Principal Findings: We performed a yeast two-hybrid screen using as bait the carboxy-terminal endodomain of S, which faces the cytosol during and after opening of the fusion pore at early stages of the virus life cycle. Here we show that the ezrin membrane-actin linker interacts with S endodomain through the F1 lobe of its FERM domain and that both the eight carboxy-terminal amino-acids and a membrane-proximal cysteine cluster of S endodomain are important for this interaction in vitro. Interestingly, we found that ezrin is present at the site of entry of S-pseudotyped lentiviral particles in Vero E6 cells. Targeting ezrin function by small interfering RNA increased S-mediated entry of pseudotyped particles in epithelial cells. Furthermore, deletion of the eight carboxy-terminal amino acids of S enhanced S-pseudotyped particles infection. Expression of the ezrin dominant negative FERM domain enhanced cell susceptibility to infection by SARS-CoV and S pseudotyped particles and potentiated S-dependent membrane fusion. Conclusions/Significance: Ezrin interacts with SARS-CoV S endodomain and limits virus entry and fusion. Our data present a novel mechanism involving a cellular factor in the regulation of S-dependent early events of infection.This work was supported by the Research Grant Council of Hong Kong (RGC#760208)and the RESPARI project of the International Network of Pasteur Institutes
