Abstract
Apricot breeding programs could be strongly improved by the availability of molecular markers linked to the main fruit quality traits. Fruit acidity is one of the key factors in consumer acceptance, but despite its importance, the molecular bases of this trait are still poorly understood. In order to increase the genetic knowledge on the fruit acidity, an F1 apricot population ('Lito' × 'BO81604311') has been phenotyped for titratable acidity and juice pH for the three following years. In addition, the contents of the main organic acids of the juice (malate, citrate, and quinate) were also evaluated. A Gaussian distribution was observed for most of the traits in this progeny, confirming their quantitative inheritance. An available simple sequence repeat (SSR)-based molecular map, implemented with new markers in specific genomic regions, was used to perform a quantitative trait loci (QTL) analysis. The molecular map was also anchored to the recently published apricot genome sequence of 'Stella.' Several major QTLs linked to fruit acidity-related traits have been identified both in the 'Lito' (no. 21) and 'BO81604311' (no. 13), distributed in five linkage groups (LG 4, 5, 6, 7, and 8). Some of these QTLs show good stability between years and their linked markers were used to identify candidate genes in specific QTLs genomic regions.

Abstract
BACKGROUND Increasing evidence indicates that β-secretase 1 (BACE1) activity and concentration in blood are candidate biomarkers for Alzheimer's disease (AD). Investigating potential demographic, biological, and clinical determinants of BACE1 in the blood matrix is the critical step to validate and qualify BACE1 bio-indicators for different contexts-of-use (CoU), such as risk assessment, early detection, diagnosis, prognosis, management of AD, and outcome of amyloid pathway targeted drugs. OBJECTIVES To evaluate the influence of age, sex, HDL-cholesterol and comorbidities (cardiovascular diseases, hypertension, diabetes) on circulating BACE-1 activity. DESIGN prospective analysis of serum samples, clinical, biological, and demographic variables. SETTING Three cohorts: 1) Memory Clinic of the Department of Internal Medicine, S. Anna University Hospital, Ferrara (Italy); 2) outpatients attending the Menopause and Osteoporosis Centre (MOC) of the University of Ferrara (Ferrara, Italy); 3) Prevention Center of the University of Ferrara. PARTICIPANTS 504 cognitively healthy individuals (median age: 62 years, interquartile range: 51-73) and 175 patients with AD (78 years, 74-82). MEASUREMENTS serum BACE1 (sBACE1), age, sex, HDL-cholesterol, major comorbidities. RESULTS Age was the strongest independent predictor of sBACE1 variance (β=0.425, p<0.0001), followed by sex (β=0.180, p<0.0001), high density lipoprotein-cholesterol (HDL-C) (β=-0.168, p<0.0001) and hypertension (β=0.111, p<0.05) (overall model, R2: 0.232). The probability of having elevated sBACE1 activity increased after 70 years of age, with women being more susceptible to higher sBACE1 activity than men. CONCLUSIONS We provide evidence about potential clinical and biological determinants of sBACE1 activity with a strong association among biomarker, female sex, and older age.

Abstract
OBJECTIVE To investigate whether high serum homocysteine (Hcy) levels is associated with the risk of developing Alzheimer's disease (AD) by performing a meta-analysis based on updated published data. METHODS We conducted a comprehensive research using Medline (Pubmed), Scopus, Web of Science and EMBASE databases to identify all prospective studies published any time to July 7, 2020 evaluating the association between elevated Hcy levels and AD risk. RESULTS From an initial screening of 269 published papers, 9 prospective investigations conducted on a total of 7474 subjects with mean follow-up of 9.5 years (range: 3.7-10) were included in the meta-analysis. Eight seventy-five of these subjects converted to AD. Hcy was significantly higher in these individuals (HRadjusted:1.48, 95% CI:1.23-1.76, I2=65.6%, p<0.0001) compared with who did not convert to AD. There was a significant publication bias (Egger's test, t=6.39, p=0.0003) and this was overcome by the trim and fill method, which allowed to calculate a bias-corrected imputed risk estimate of HRadjusted:1.20, 95% CI:1.01-1.44, Q value=41.92. CONCLUSIONS The present meta-analysis found that having higher Hcy increases the risk of AD in the elderly and this finding is consistent with the widely suggested role of this non-proteinogenic α-amino acid in AD neurodegeneration.

Abstract
The catalytic mechanism of 6-phosphogluconate dehydrogenase requires the inversion of a Lys/Glu couple from its natural ionization state. The pKa of these residues in free and substrate bound enzymes has been determined measuring by ITC the proton release/uptake induced by substrate binding at different pH values. Wt 6-phosphogluconate dehydrogenase from Trypanosoma brucei and two active site enzyme mutants, K185H and E192Q were investigated. Substrate binding was accompanied by proton release and was dependent on the ionization of a group with pKa 7.07 which was absent in the E192Q mutant. Kinetic data highlighted two pKa, 7.17 and 9.64, in the enzyme-substrate complex, the latter being absent in the E192Q mutant, suggesting that the substrate binding shifts Glu192 pKa from 7.07 to 9.64. A comparison of wt and E192Q mutant appears to show that the substrate binding shifts Lys185 pKa from 9.9 to 7.17. By comparing differences in proton release and the binding enthalpy of wt and mutant enzymes, the enthalpic cost of the change in the protonation state of Lys185 and Glu192 was estimated at ≈6.1kcal/mol. The change in protonation state of Lys185 and Glu192 has little effect on Gibbs free energy, 240-325cal/mol. However proton balance evidences the dissociation of other group(s) that can be collectively described by a single pKa shift from 9.1 to 7.54. This further change in ionization state of the enzyme causes an increase of free energy with a total cost of 1.2-2.3kcal/mol to set the enzyme into a catalytically competent form.

Abstract
Retinal diseases (RD), including diabetic retinopathy, are among the most important eye diseases in industrialized countries. RD is characterized by abnormal angiogenesis associated with an increase in cell proliferation and apoptosis. Hypoxia could be one of the triggers of the pathogenic mechanism of this disease. A key regulatory component of the cell's hypoxia response system is hypoxia-inducible factor 1 alpha (HIF-1α). It has been demonstrated that the induction of HIF-1α expression can be also achieved in vitro by exposure with cobalt chloride (CoCl2), leading to an intracellular hypoxia-like state. In this study we have investigated the effects of CoCl2 on human retinal epithelium cells (hRPE), which are an integral part of the blood-retinal barrier, with the aim to determine the possible role of oxidative stress in chemical hypoxia-induced damage in retinal epithelial cells. Our data showed that CoCl2 treatment is able to induce HIF-1α expression, that parallels with the formation of reactive oxygen species (ROS) and the increase of lipid 8-isoprostanes and 4-hydroxynonenal (4-HNE) protein adducts levels. In addition we observed the activation of the redox-sensitive transcription factor nuclear factor-kappaB (NFkB) by CoCl2 which can explain the increased levels of vascular endothelial growth factor (VEGF). The increased number of dead cells seems to be related to an apoptotic process. Taken together these evidences suggest that oxidative stress induced by hypoxia might be involved in RD development through the stimulation of two key-events of RD such as neo-angiogenesis and apoptosis.

Abstract
Amygdalin is a cyanogenic glycoside found in the seeds of several plants belonging to the Rosaceae family. Cyanogenic glycosides can be specifically probed by Raman spectroscopy due to an inherent nitrile group which shows a well-resolved band near 2245 cm(-1). In the current study the subcellular distribution of amygdalin in thin apricot (Prunus armeniaca) seed sections is probed by high-resolution Raman imaging with a step size of 2.5 μm. Further, Raman images and line maps were collected from four apricot seeds with step sizes between 30 and 70 μm. The data were processed by functional group mapping and the spectral unmixing algorithm vertex component analysis. Spectral contributions of amygdalin, lipids, and cellulose were identified. One seed had low amygdalin content in its center and higher content toward its epidermis. The other three specimens showed different distributions of amygdalin, with highest concentration in the center and local concentration spots throughout the seed. We conclude from these preliminary results on Raman imaging in apricot seeds that amygdalin is unevenly distributed and its location does not follow the same pattern for all seeds. The observed biological variability of the amygdalin distribution cannot yet be explained satisfactorily and requires further investigation.

Abstract
In apricot the bitter flavor of seeds is determined by the amount of amygdalin, a cyanogenic glucoside whose cleavage by endogenous enzymes, upon seed crushing, releases toxic hydrogen cyanide. The presence of such a poisonous compound is an obstacle to the use and commercialization of apricot seeds for human or animal nutrition. To investigate the genetic loci involved in the determination of the bitter phenotype a combined genetic and biochemical approach was used, involving a candidate gene analysis and a fine phenotyping via quantitative nuclear magnetic resonance, on an F1 apricot progeny. Seven functional markers were developed and positioned on the genetic maps of the parental lines Lito and BO81604311 and seven putative QTLs for the bitterness level were determined. In conclusion, this analysis has revealed some loci involved in the shaping of the bitterness degree; has proven the complexity of the bitter trait in apricot, reporting an high variance of the QTLs found over the years; has showed the critical importance of the phenotyping step, whose precision and accuracy is a pre-requisite when studying such a multifactorial character.

Abstract
The authors present their experience with a new crossed condylar and osteotomy plate, which is innovative because of the features of its design, and the instrumentation used for its application, as compared to the traditional AO blade plate. The plate is called "fork-shaped" because there are 2 prongs in place of the blade with a "U" profile, and it involves the use of more accurate and less traumatic instrumentation to implant it. The results of a study conducted on a group of 20 patients, who were homogeneous for pathology and surgery, treated by a fork-shaped osteotomy plate, compared with an equal number of patients treated by a blade plate, are reported. The results were better in the group treated with a fork plate because there was a more accurate correspondence with the preoperative planning, and because there were fewer intraoperative complications, and time required for surgery was shorter.

Abstract
Osteosynthesis with a humeral anchor nail may be listed along with other methods of intramedullary fixation for the treatment of diaphyseal fractures. The authors report their experience with 33 cases of humeral fractures treated between July 1987 and July 1991. Results were excellent in 61% of the cases, good in 24%, and fair in 15%; no particular complications were reported. The authors believe that the anchor nail constitutes a system of osteosynthesis involving only a small amount of trauma, and allowing for positive elastic stability for the consolidation of the fracture, as well as being a sufficiently safe system so that immobilization in plaster may be avoided. When compared with other systems of intramedullary fixation, the anchor nail is more effective than the Rush nail from a mechanical point of view, and the Kuntscher nail from a biological one.

Abstract
The size and shape of the patella make it suitable for the partial replacement of a femoral or tibial condyle resected for tumour, or destroyed by trauma. It can provide a good articular surface and may give satisfactory knee function. Nineteen cases of patellar grafts are presented, with follow-up from two to nine years. Good consolidation of the graft and fair stability of the joint were obtained; the range of movement was 90 degrees or more in 79% of cases. In contrast with an allograft of a femoral or tibial condyle, the technique described does not need an allograft bank, has a lower risk of infection, and allows better and quicker consolidation and revascularisation of the grafts, as well as a better range of movement at the knee, probably because of the lack of fibrosis from immunological reaction. Merle d'Aubigné's technique, using a patellar graft with a vascular muscle pedicle, is useful only for some cases, requires a longer period of immobilisation and weakens the extensor apparatus. Our series shows that consolidation and revascularisation of a patellar graft can occur in the absence of a pedicle.

Abstract
127 cases of aneurysmal bone cyst are analysed, seventy two of which were followed up from one to fifteen years after treatment. Statistics on sex, age, site and localisation are reported. Symptoms, radiographic features, histological appearances and differential diagnosis are discussed. In half the cases the cyst was clearly shown to be of subperiosteal origin. The aetiology is unknown, but the pathogenesis seems to consist of a haemorrhagic and hyperplastic (not neoplastic) process which is progressive but has a tendency to become stabilised on reaching a certain point of maturation. Local excision is indicated or, in cases where this is difficult to carry out, radiotherapy. Recurrences occurred in 12 per cent of the cases, always within one year after operation. All cases were eventually cured and there was no evidence of malignant transformation.
