and gene polymorphisms influence graft survival, and response to therapy in kidney transplantation.

Background: Antibody-mediated rejection is a significant cause of kidney transplant failure. Recent studies have shown that the MHC class I gene influences the transplantation outcome. However, the role of the primary receptor, NKG2D, has yet to be explored.

The double-sided of human leukocyte antigen-G molecules in type 1 autoimmune hepatitis.

Unlabelled: The immunomodulatory effects of HLA-G expression and its role in cancers, human liver infections and liver transplantation are well documented, but so far, there are only a few reports addressing autoimmune liver diseases, particularly autoimmune hepatitis (AIH).

Method And Materials: We analyzed the genetic and phenotypic characteristics of HLA-G in 205 type 1 AIH patients (AIH-1) and a population of 210 healthy controls from Sardinia (Italy).

Results: Analysis of the HLA-G locus showed no substantial differences in allele frequencies between patients and the healthy control population.

Effect of Suckling Management and Ewe Concentrate Level on Methane-Related Carbon Footprint of Lamb Meat in Sardinian Dairy Sheep Farming.

The aim of this study was to estimate the methane-linked carbon footprint (CF) of the suckling lamb meat of Mediterranean dairy sheep. Ninety-six Sarda dairy ewes, divided into four groups of 24 animals each, were assigned to 2 × 2 factorial design. The experiment included the suckling lamb feeding system: traditional (TS), in which lambs followed their mothers on pasture during grazing time, vs.

The Design of a New Catheter for Transcervical Artificial Insemination in Ewes.

In ovine species, transcervical artificial insemination (TCAI) is limited by the poor quality of frozen-thawed semen and by the convoluted cervical lumen hampering the passage of inseminating devices. The aim of the study was to test the efficiency of three newly designed catheters with bent tips of 3.5 mm, 5.

Effect of Dams and Suckling Lamb Feeding Systems on the Fatty Acid Composition of Suckling Lamb Meat.

The effects of the dams and suckling lamb feeding systems on the fatty acid (FA) profile of lamb meat are reviewed in this article. The suckling lamb can be considered a functional monogastric, and therefore, its meat FA composition is strongly influenced by the FA composition of maternal milk. The major source of variation for ewe milk FA composition is represented by pasture amount and type.

Animal board invited review - Beef for future: technologies for a sustainable and profitable beef industry.

The global consumption, notably in developing countries, and production of beef are increasing continuously, and this requires the industry to improve performance and to reduce the environmental impact of the production chain. Since the improvement in efficiency and the highest impacts occur at farm level, it is appropriate to focus on the profitability and environmental sustainability of these enterprises. In many areas of the world, beef production is economically and socially relevant because it accounts for a significant portion of the agricultural production and represents a vital economic activity in mountain and hill districts of many regions, where few alternatives for other agricultural production exist.

Human Leukocyte Antigen Complex and Other Immunogenetic and Clinical Factors Influence Susceptibility or Protection to SARS-CoV-2 Infection and Severity of the Disease Course. The Sardinian Experience.

Aim: SARS-CoV-2 infection is a world-wide public health problem. Several aspects of its pathogenesis and the related clinical consequences still need elucidation. In Italy, Sardinia has had very low numbers of infections.

Effect of extruded linseed supplementation on blood metabolic profile and milk performance of Saanen goats.

This study assessed the effects of dietary supplementation with extruded linseed on milk yield and composition, milk fatty acid (FA) profile and renal and hepatic metabolism of grazing goats in mid-lactation. Forty Saanen goats were divided into two isoproductive groups: one group was fed the control diet (CON) composed of hay and pelleted concentrate and the other group was supplemented with additional 180 g/day of extruded linseed (LIN; dry matter basis), which supplied 70 g/day of fat per head for 9 weeks. Animals grazed on pasture for ∼3 h/day after the first of the 2 daily milkings.

Excretion pattern of aflatoxin M1 in milk of goats fed a single dose of aflatoxin B1.

The feedstuffs used in dairy animals must be able to give consumers confidence about the wholesomeness of milk with regard to aflatoxin contamination. The aim of this study was to determine the excretion patterns of aflatoxin M(1) (AFM1) in the milk of dairy goats fed a single dose of pure aflatoxin B(1) (AFB1), which can occasionally occur if feeds are infected by hot-spot growth of molds that produce aflatoxins. Five dairy goats in midlactation were administered 0.

Two patients with balanced translocations and autistic disorder: CSMD3 as a candidate gene for autism found in their common 8q23 breakpoint area.

Recent studies estimated a rate of 3-5% of cytogenetic abnormalities involving many different chromosomes in autistic spectrum disorders (ASDs). Here, we report on two unrelated male patients with de novo translocations, autistic behaviour and psychomotor delay. These two patients carry a balanced chromosome translocation t(5;8)(q14.

IRAK-M is involved in the pathogenesis of early-onset persistent asthma.

Asthma is a multifactorial disease influenced by genetic and environmental factors. In the past decade, several loci and >100 genes have been found to be associated with the disease in at least one population. Among these loci, region 12q13-24 has been implicated in asthma etiology in multiple populations, suggesting that it harbors one or more asthma susceptibility genes.

Prenatal diagnosis of a mosaic supernumerary marker iso (8p) (tetrasomy 8p): discordance between chorionic villi culture and amniotic fluid karyotypes.

We describe the first case of mosaic supernumerary marker iso (8p) displaying a karyotype discordance between chorionic villi (CV) and amniotic fluid (AF) cultures during prenatal cytogenetic diagnosis. In the first trimester, cytogenetic analysis after chorionic villi sampling (CVS) was normal in all metaphases in the short-term cytotrophoblast cell culture, but an undefined supernumerary marker was detected in 60% of mesenchymal cells in the long-term CV culture. Informed of the mosaicism, the couple selected amniotic fluid sampling as a second-trimester confirmatory diagnostic procedure.

Parathyroid function and bone metabolism in children with beta thalassaemia major: effects of sex steroid treatment.

Objective: Data on parathyroid function in patients with homozygous beta-thalassaemia are discordant. Moreover, there is no report on the effects of sexual steroid treatment on bone metabolism in these patients.

Methods: Serum parathyroid hormone (PTH), calcitonin (CT) and osteocalcin (GLA protein) levels were measured in 121 patients.

Endocrine functioning in multitransfused prepubertal patients with homozygous beta-thalassemia.

Endocrine function was evaluated in 20 prepubertal patients with homozygous beta-thalassemia treated with frequent transfusions and long term iron chelation therapy. FSH, LH, PRL, and TSH secretion were evaluated by LRH and TRH testing and L-dopa and ACTH were used to assess GH and adrenocortical reserve. No statistically significant differences were found between FSH, LH, PRL, GH, and cortisol secretion in the patients and in normal subjects.

Suppression of electroacupuncture(EA)-induced beta-endorphin and ACTH release by hydrocortisone in man. Absence of effects on EA-induced anaesthesia.

Auricular electroacupuncture (EA) increased plasma ACTH and beta-endorphin levels significantly in 10 patients receiving EA as an analgesic aid during surgery. Pre-treatment with iv hydrocortisone (200 mg) completely suppressed both ACTH and beta-endorphin release in response to EA without significantly affecting EA anaesthesia in 6 other patients and in a patient with Addison's disease.

The TRH induced PRL release in patients with autonomous thyroid nodules before and after surgical treatment.

Total and free thyroid hormones (T3, T4, FT3, FT4), TSH and PRL were determined in basal conditions and after stimulation with TRH in 32 patients affected by autonomous thyroid nodules before and after nodulectomy and in 24 control subjects. Only 7 patients were clinically thyrotoxic and thyroid hormone concentrations were slightly elevated in most cases. In untreated patients the increment (delta) in PRL after TRH was significantly lower than in normal subjects but was not as severely depressed as that of TSH.

Acute effect of atenolol on serum thyroid hormones in hyperthyroid patients.

The effect of atenolol on serum thyroid hormones levels is controversial. To get more information on this problem we studied the effect of propranolol and atenolol on plasma thyroid hormone concentrations in 20 thyrotoxic patients. Propranolol but not atenolol caused a significant decrease in T3 levels whereas no significant changes wee observed in T4 levels after both propranolol and atenolol administration.

Effect of long-term treatment with sodium valproate on gonadotrophin and prolactin secretion in paediatric patients.

1 Luteinizing hormone (LH), follicle stimulating hormone (FSH) and prolactin levels were measured in twenty paediatric patients receiving sodium valproate (30 mg/kg body weight daily) and in ten control subjects under control conditions and following LRH-TRH administration. In addition, baseline GH levels were measured in the two groups. 2 No significant differences were observed between the basal and stimulated hormone levels in the two groups.

Growth hormone (GH) secretion in hepatic encephalopathy.

Elevated plasma concentrations and abnormal secretory patterns of GH have been found in patients with cirrhosis of the liver. Displacement of brain dopaminergic monoamines by false "neurotransmitters' produced in the gut has been postulated as a cause of encephalopathy. In this study basal GH plasma levels and their response to TRH and L-DOPA were determined in thirty-nine cirrhotic patients and fifteen controls.
