A divergent selection experiment for environmental variance of litter size variance was carried out in rabbits over thirteen generations. The aim of this study was to evaluate the inflammatory response in the two lines of the experiment, in order to analyse the effect of selection on susceptibility to diseases after challenging to stressful situations, such as 24 h after the first delivery. A total of 78 females were used in this study, 39 from each line. The line selected for litter size heterogeneity (the high line) showed lower white blood leukocyte count (WBC; −0.87 × 103/µL), lower percentage of basophils (−0.11%), higher concentration of TNF-α (+13.8 pg/mL), and greater concentration of CRP (+38.1 µg/mL) than the line selected for litter size homogeneity (the low line). The high line had also higher concentrations of bilirubin, cholesterol, gamma-glutamyl transferase (GGT) and alkaline phosphatase (ALP) compared to the low line (difference between lines were +0.08 µmol/L, +0.14 µmol/L, +0.35 U/L and +2.4 U/L, respectively). The high line showed higher inflammatory response than the low line, in accordance with a larger susceptibility to infectious disorders. In conclusion, the line selected to increase litter size environmental variability seems to have poor capacity coping with environmental stressors. Therefore, selection for litter size environmental variability can be a useful way to improve animal welfare.

A divergent selection experiment on environmental sensitivity was performed in rabbits. The aim of this study was to estimate the correlated response in kits’ weight and its survival, and weight distance from birth to weaning. Weight distance was calculated as the absolute values of the differences between the individual value and the mean value of its litter. Also, relationship between probability of survival at 4 d of age and weight at birth was studied. Environmental sensitivity was measured as litter size variability. A total of 2484 kits from 127 does of the low line (selected for reducing litter size variability) and 1916 kits of 114 does of the high line (selected for increasing litter size variability) of the 12th generation were weighed. Bayesian methodology was used to estimate the correlated response to selection, and LOGISTIC procedure of SAS was used to estimate the relationship between weight and probability of survival. Both lines showed similar individual weight at birth and at weaning, and similar survival at birth and at 4 d of age. Survival at weaning was higher in the low line than in the high line (0.67 and 0.62; P= 0.93). Weight distance was higher at birth but lower at weaning in the low line (47.8 g and 54.1 g; P=0.98). Kit’s weight at birth affected its survival. In conclusion, selection for environmental sensitivity showed correlated response in kits survival and in homogeneity of litter weight at weaning.

A divergent selection for litter size residual variability has been carried out in rabbits during 12 generations. Litter size residual variability was estimated as phenotypic variance of litter size within females after correcting for the year-season and the parity-lactation status effects. Stress causes an increase in core body temperature. Infrared thermography (IRT) has been shown to be a useful technique for identifying changes in body temperature emissivity. The aim of this work is to study the correlated response to selection for litter size residual variability in body temperature emissivity at natural mating. Natural mating can be considered a stressful stimulus for does. Temperature was measured in the eyeball by IRT before mating (basal temperature) and after 5 min, 30 min, and 60 min in does of the lines selected to decrease and to increase litter size residual variability (i.e., the Low and the High lines). Both lines showed similar basal temperature. Eyeball temperature was increased slightly in the Low line from basal state to 5 min after stressful stimulus (from 35.69 °C to 36.32 °C), and this increase remained up to 60 min after stress (36.55 °C). The High line showed a higher temperature than the Low line at 30 min (+0.96 °C, p = 0.99). At 60 min, temperature was similar between lines. The evolution of temperature was different between lines: the High line reached the peak of temperature later than the Low line (at 30 min vs. 5 min), and its peak was higher compared to the Low line (36.95 °C vs. 36.32 °C). In conclusion, the does selected for reducing litter size variability showed a lower increase in temperature after a stressful stimulus, therefore showing lower stress and consequently better welfare.

<p>A divergent selection experiment for litter size variability was carried out in rabbits. The litter size variability was estimated as the phenotypic variance of litter size within female. The aim of this study was to assess the effect of selecting for litter size variability on early embryonic development and survival after 7 generations of divergent selection (high and low variability lines). A total of 30 non-lactating multiparous does per line were used. The ovulation rate and early embryonic development were analysed using Bayesian methodology. Ovulation rate was not affected by the selection process. At 28 h of gestation, embryonic development and survival were similar in both lines. At 48 h of gestation, the majority of embryos in the high line were in the early morulae stage. The high line had a higher proportion of early morulae (79.54 vs. 53.43%; P=0.94) and a lower proportion of compacted morulae (20.46 vs. 46.57%; P=0.93%) than the low line. At 72 h of gestation, the high line had 1.59 fewer embryos than the more homogeneous line (P=0.85), due to reduced embryonic survival (0.60 vs. 0.74; P=0.93). The high line continued to show a higher proportion of early morulae (21.01 vs. 3.69%; P=0.93) and a lower proportion of compacted morulae and blastocysts (78.99 vs. 96.31%; P=0.94) than the low line at 72 h of gestation, indicative of reduced embryonic development. In conclusion, selection for homogeneity in litter size had a positive impact on embryonic traits.</p>

Light chain deposition disease (LCDD) is a rare multisystemic disorder associated with plasma cell proliferation. It mainly affects the kidney, but liver and heart involvement may occur, sometimes mimicking the picture of systemic amyloidosis. Liver disease in LCDD is usually asymptomatic and exceptionally manifests with severe cholestatic hepatitis. We report the case of a 66-year-old female with κ-LCDD and cast nephropathy in the setting of symptomatic multiple myeloma who, after a first cycle of bortezomib-dexamethasone chemotherapy, developed severe and rapidly worsening intrahepatic cholestasis secondary to liver κ-light chain deposition. Intrahepatic cholestasis was attributed to LCDD on the basis of the liver histology and exclusion of possible diagnoses. Chemotherapy was maintained and resulted in progressive resolution of cholestasis. We report here an uncommon presentation of LCDD, with prominent liver involvement that fully recovered with bortezomib-based chemotherapy, and briefly review the relevant literature.

This in vitro study analyses the biochemical interaction between saliva and three types of dental composite resins (a direct resin, an indirect resin and a dual-cure resin used for cementation of indirect dental restorations). The resin samples were obtained following a specific protocol and in line with the producers� recommendations; the resin samples were incubated with saliva samples collected from 19 healthy volunteers. The obtained results showed that the tested composite resins did not produce significant changes in oxidative stress parameters that were analysed (albumin, uric acid, GGT / gamma glutamyl transferase, OXSR-1 / oxidative stress responsive kinase 1) and do not influence the inflammatory salivary status reflected by the levels of IL-6 - an inflammatory marker.

AimsPublic Health England has identified that in COVID-19, death rates among ethnic minorities far exceeds that of the white population. While the increase in ethnic minorities is likely to be multifactorial, to date, no studies have looked to see whether values for routine clinical biochemistry parameters differ between ethnic minority and white individuals.MethodsBaseline biochemical data for 22 common tests from 311 SARS-CoV-2 positive patients presenting to hospital in April 2020 in whom ethnicity data were available was retrospectively collected and evaluated. Data comparisons between ethnic minority and white groups were made for all patient data and for the subset of patients subsequently admitted to intensive care.ResultsWhen all patient data were considered, the ethnic minority population had statistically significant higher concentrations of C reactive protein (CRP), aspartate aminotransferase and gamma-glutamyl transferase, while troponin T was higher in the white group. A greater proportion of ethnic minority patients were subsequently admitted to intensive care, but when the presenting biochemistry of this subset of patients was compared, no significant differences were observed between ethnic minority and white groups.ConclusionOur data show for the first time that routine biochemistry at hospital presentation in COVID-19 differs between ethnic minority and white groups. Among the markers identified, CRP was significantly higher in the ethnic minority group pointing towards an increased tendency for severe inflammation in this group.

Abstract Background Nanomedicine contributes to the efficiency of pharmacological treatments and progresses rapidly. The present study was designed to produce exopolysaccharide (BSEPS) from Bacillus subtilis sp. strain reported in our previous study was further characterized, and its BSEPS for synthesis of the nanoparticle Ag-BSEPS using microwave heating to determine the possible effects of a prepared solution containing Ag-BSEPS versus thioacetamide (TAA) evoked liver fibrosis in Wister albino rats. Nanoparticles with silver (Ag) core have been synthesized in an aqueous solution after exposure of BSEPS to periodate oxidation. Animals were split into four groups: I - control rats, water ad libitum for 6 weeks; II - rats were injected with TAA 200 mg/kg-1 3 times/week for 4 weeks IP; III - Ag-BSEPS 100 mg/kg-1 IP twice a week for 6 weeks; and IV - TAA, as group II followed by Ag-BSEPS as group III. The antifibrotic effects of Ag-BSEPS were appraised by determining different hepatotoxicity indices, oxidative stress, and inflammatory and liver fibrosis markers. Results Nanoparticles were obtained with a diameter size range of 50–100 nm characterized by SEM and TEM without using any harmful reagents. Results evinced considerably reduced activity of liver functions such as transaminases (AST, ALT), gamma-glutamyl transferase (GGT), and alkaline phosphatase (ALP) in the group which received TAA followed by Ag-BSEPS compared to the other group which received only TAA. In the current results, the administration of Ag-BSEPS showed an improvement in the proinflammatory cytokines. On the contrary, the antioxidant enzymes in liver homogenates revealed significant improvement (concentration of glutathione peroxidase (GSH-PX), superoxide dismutase (SOD), and catalase (CAT) increases) in animals with TAA-induced liver damage followed by Ag-BSEPS. Moreover, the activities of the fibrotic markers transforming growth factor-beta 1(TGF-β1) and type III pro-collagen (PCIII) were increased in liver tissues in the group which was given TAA alone as compared to the controls. The percentage of fibrosis of hepatic tissue had a positive correlation with the levels of PCIII and TGF-β1, followed by Ag-BSEPS compared to the TAA group without nanocomposite treatment. Microscopic examinations revealed inhibitory effects of Ag-BSEPS on inflammatory changes and deterrent of liver fibrosis. Conclusion It was suggested that the biochemical and histological amelioration observed in Ag-BSEPS (100 mg/kg-1 twice a week for 6 weeks) treated the fibrotic rats.
