Permanent hypoparathyroidism is an uncommon disease resulting most frequently from neck surgery. It has been associated with visceral calcifications but few studies have specifically this in patients with post-surgical hypoparathyroidism. The aim of the present study was to assess the prevalence of basal ganglia and carotid artery calcifications in patients with long-term post-thyroidectomy hypoparathyroidism compared with a control population.
 
  Case-control study.
 
  A cross-sectional review comparing 29 consecutive patients with permanent postoperative hypoparathyroidism followed-up in a tertiary reference unit for Endocrine Surgery with a contemporary control group of 501 patients who had an emergency brain CT scan. Clinical variables and prevalence of basal ganglia and carotid artery calcifications were recorded.
 
  From a cohort of 46 patients diagnosed with permanent hypoparathyroidism, 29 were included in the study.  https://www.selleckchem.com/products/Decitabine.html  The mean duration of disease was 9.2 ± 7 years. Age, diabetes, hypertension, smoking and dyslipidemia were similarly distributed in case and control groups. The prevalence of carotid artery and basal ganglia calcifications was 4 and 20 times more frequent in patients with permanent hypoparathyroidism, respectively. After propensity score matching of the 28 the female patients, 68 controls were matched for age and presence of cardiovascular factors. Cases showed a four-fold prevalence of basal ganglia calcifications, whereas that of carotid calcifications was similar between cases and controls.
 
  A high prevalence of basal ganglia calcifications was observed in patients with post-surgical permanent hypoparathyroidism. It remains unclear whether carotid artery calcification may also be increased.

Recent studies suggested that mice should be housed slightly below their thermoneutral temperature (26°C). On the other hand, the external temperature, also known as a zeitgeber, can reset the circadian rhythm. However, whether housing temperature affects the circadian oscillators of the liver remains unknown. Therefore, we have compared the effect of two housing temperatures, namely 21°C (conventional; TC) and 26°C (thermoneutral; TN), on the circadian rhythms in mice. We found that the rhythmicity of food intake showed an advanced phase at TC, while the activity was more robust at TN, with a prolonged period onset. The serum levels of norepinephrine were remarkably induced at TC, but failed to oscillate rhythmically at both temperatures. Likewise, circulating glucose levels were increased but were non-rhythmic under TC. Both total cholesterol and triglycerides levels were induced at TN, but showed an advanced phase under TC. Additionally, the expression of hepatic metabolic genes and clock genes remained rhythmic at both temperatures, with the exception of G6Pase, Fasn, Cpt1a and Cry2, at TN. Nevertheless, the liver histology examination did not show any significant changes in response to housing temperature. Although the non-consistent trends of phase changes in each temperature, our results suggest a non-reductant role of temperature in mouse internal rhythmicity resetting. Thus, the temperature-controlled internal circadian synchronization within organs should be taken into consideration when optimizing housing temperature for mice.
  Autonomous cortisol secretion (ACS) is a condition with ACTH-independent cortisol overproduction from adrenal incidentalomas (AI) or adrenal hyperplasia. The hypercortisolism is often mild, and most patients lack typical clinical features of overt Cushing's syndrome (CS). ACS is not well defined and diagnostic tests lack validation.
 
  Retrospective study of 165 patients with AI evaluated clinically and by assay of morning plasma ACTH, late-night saliva cortisol, serum DHEA sulphate (DHEAS), 24-h urine-free cortisol, and cortisol after dexamethasone suppression.
 
  Patients with AI (n = 165) were diagnosed as non-functioning incidentalomas (NFI) (n = 82) or ACS (n = 83) according to current European guidelines. Late-night saliva cortisol discriminated poorly between NFI and ACS, showing a high rate of false-positive (23/63) and false-negative (38/69) results. The conventional low-dose dexamethasone suppression test (LDDST) did not improve the diagnostic specificity, compared with the 1 mg overnight DST. Receiove the diagnostic workup of ACS.Late embryogenesis abundant (LEA) proteins are highly hydrophilic and thermostable proteins that could be induced by abiotic stresses in plants. Previously, we have isolated a group 3 LEA gene TdLEA3 in wheat. The data show that TdLEA3 was largely disordered under fully hydrated conditions and was able to prevent the inactivation of lactate dehydrogenase (LDH) under stress treatments. In the present work, we further investigate the role of TdLEA3 by analyzing its expression pattern under abiotic stress conditions in two contrasting wheat genotypes and by overexpressing it in Arabidopsis thaliana. Transgenic Arabidopsis plants showed higher tolerance levels to salt and oxidative stress compared to the wild type plants. Meanwhile, there was significant increase in antioxidants, catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) accumulation, increased root length and significant reduction in oxidants, hydrogen peroxide (H2O2) and malondialdehyde (MDA) content in the leaves of transgenic lines under stress conditions. Accordingly, Q-PCR results indicate that the higher levels of expression of different ROS scavenging genes (AtP5CS, AtCAT, AtPOD and AtSOD) and abiotic stress related genes (RAB18 and RD29B) were detected in transgenic lines. In addition, they showed increased resistance to fungal infections caused by Fusarium graminearum, Botrytis cinerea and Aspergillus niger. Finally, Q-PCR results for biotic stress related genes (PR1, PDF1.2, LOX3 and VSP2) showed differential expression in transgenic TdLEA3 lines. All these results strongly reinforce the interest of TdLEA3 in plant adaptation to various stresses.
