Improving Fe uptake in crops, enabling them to grow in Fe-depleted soils, has become a major focal interest. The secretion of Fe-mobilizing coumarins by plant roots recently emerged as an important factor allowing nongrass species to cope with low Fe bioavailability. The main molecular actors involved in the biosynthesis and secretion of coumarins have been identified, but the precise regulatory mechanisms that tune their production remain poorly understood. Here, we review the recent progress in coumarin synthesis and transport in plants and future research directions to gain knowledge of these mechanisms, which will offer novel opportunities for improving plant growth and health and for generating Fe-fortified crops.Nectar is the most important reward offered by flowering plants to pollinators for pollination services. Since pollinator decline has emerged as a major threat for agriculture, and the food demand is growing globally, studying the nectar gland is of utmost importance. Although the genetic mechanisms that control the development of angiosperm flowers have been quite well understood for many years, the development and maturation of the nectar gland and the secretion of nectar in synchrony with the maturation of the sexual organs appears to be one of the flower's best-kept secrets. Here we review key findings controlling these processes. We also raise key questions that need to be addressed to develop crop ecological functions that take into consideration pollinators' needs.
The objective was to evaluate the clinical and biological factors associated with negative
Tc-MIBI scanning in patients with primary hyperparathyroidism (PHPT).

A retrospective observational study was designed in 195 patients (mean age 59.2±13.0years; 77% woman) with PHPT (calcium 11.3±1.1mg/dl and PTH 218±295pg/ml) studied in endocrinology setting between 2013 and 2020. An univariate and multivariate analysis was made to evaluate the clinical and biological factors associated with negative
Tc-MIBI scanning.

50 patients (26%) with negative
Tc-MIBI scanning had lower PTH levels (146±98 vs. 244±334; p<0.001), adenomas with smaller sonographic dimensions (maximum diameter 1.2±0.4 vs. 1.7±0.9cm; p=0.001 and volume 0.36±0.43 vs. 1.7±4.1cm
; p<0.001), localized more frequently in upper parathyroid glands (37% vs. 14%; p=0.005) and associated more frequently to thyroid nodules (72% vs. 57%; p=0.045) than patients with positive scanning. 116 patients were operated and parathyroid adenomas were smaller (maximum diameter 1.3±0.5 vs. 1.9±1.1cm; p=0.008 and volume 0.30±0.20 vs. 1.2±1.1cm
; p<0.001), less heavy (567±282 vs. 1470±1374mg; p=0.030) and were localized more frequently in upper situation (65% vs. 16%; p<0.001) than patients with positive scanning. In the multivariate analysis an independent association between negative
Tc-MIBI scanning and size of removed adenoma ≤1cm (OR 5.77; 95% CI 1.46-22.71) and upper adenoma localization were observed (OR 8.05; 95% IC 2.22-29.16).

One in four patients studied for PHPT had a negative
Tc-MIBI scanning and were independent associated with size of adenoma ≤1cm and upper adenoma localization.
One in four patients studied for PHPT had a negative 99mTc-MIBI scanning and were independent associated with size of adenoma ≤1cm and upper adenoma localization.In a previous Phase 2 study, olesoxime had a favorable safety profile. Although the primary endpoint was not met, analyses suggested that olesoxime might help in the maintenance of motor function in patients with Types 2/3 SMA. Selleckchem GPR84 antagonist 8 This open-label extension study (OLEOS) further characterizes the safety, tolerability and efficacy of olesoxime over longer therapy durations. In OLEOS, no new safety risks were identified. Compared to matched natural history data, patients treated with olesoxime demonstrated small, non-significant changes in motor function over 52 weeks. Motor function scores were stable for 52 weeks but declined over the remainder of the study. The greatest decline in motor function was seen in patients ≤15 years old, and those with Type 2 SMA had faster motor function decline versus those with Type 3 SMA. Previous treatment with olesoxime in the Phase 2 study was not protective of motor function in OLEOS. Respiratory outcomes were stable in patients with Type 3 SMA >15 years old but declined in patients with Type 2 SMA and in patients with Type 3 SMA ≤15 years old. Overall, with no stabilization of functional measures observed over 130 weeks, OLEOS did not support significant benefit of olesoxime in patients with SMA.Hereditary myotonia (HM) is a genetic disorder that occurs due to mutations in the chloride channel and results in delayed relaxation of the skeletal muscles. HM has been described in 12 dog breeds, and in five of them, molecular studies of this disorder were performed and mutations in the CLCN1 gene were described. In this study, an affected American Bulldog with HM clinically characterized by muscle hypertrophy, myotonic discharges, and nondystrophic myotonia with a "warm-up" phenomenon was evaluated, and the candidate canine CLCN1 gene was sequenced. The molecular analysis revealed a frameshift mutation NM_001003124.2c.436_437insCTCT that resulted in a frameshift and a premature stop codon NP_001003124.1pTyr146SerfsTer49 . Two aberrant alternative CLCN1 transcripts were observed in an affected dog, the expected transcript with the 4 bp insertion, NM_001003124.2r.436_437insctct, and an unexpected transcript containing parts of intron 6 in addition to the insertion in exon 4, NM_001003124.2[r.436_437insctct;r.774_775ins79]. In conclusion, the frameshift mutation in the CLCN1 gene is associated with autosomal recessive HM in American Bulldog and this study constitutes the first description of the disease in this breed.
To elucidate the differences in etiology of dyskinetic cerebral palsy (DCP) between term-born and preterm-born children and its relationship to functional outcomes.

We determined the etiology of DCP based on the clinical course and brain MRI of 163 term-born and 136 preterm-born children. Information about genetic abnormality was also collected if available. Functional outcomes were compared between the two major etiologies in each group, i.e., hypoxic ischemic encephalopathy (HIE) and bilirubin encephalopathy (BE), using four standardized classification systems, i.e., Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), Communication Function Classification System (CFCS), and Eating and Drinking Ability Classification System (EDACS).

The most common etiologies were HIE (123/163) in term-born and BE (93/136) in preterm-born children. Genetic mutations were identified in 14 of 30 term-born children with no other known etiology. GMFCS levels of the preterm children with BE were significantly poorer than those of term children with HIE (p<0.
