The simultaneous analysis of the maximum number of chemical elements present in plant tissues provides more comprehensive information about their chemical constitution and increases the number of characteristics for the selection process in various plant breeding programs. The objective of this study was to analyze productivity, grain yield, and concentration of chemical elements in tissues of clones to study phenotypic diversity and estimate genetic parameters for use in breeding. This experiment was carried out in Manaus, Amazonas, Brazil, in randomized blocks with four replications. The concentrations of elements in various organs were quantified using total reflection X-ray fluorescence (TXRF). Genetic parameters and genetic divergence were estimated, and genotypes were clustered using the UPGMA hierarchical method and non-metric multidimensional scaling analysis. The study allowed us to differentiate the performance of the clones in terms of the absorption of essential and non-essential chemical elements for plant development and to analyze the correlation of the characteristics in the selection process. TXRF efficiently characterizes the presence and concentration of multiple elements, aiding genotype discrimination for improvement.

Chapter 4: DIFFERENTIAL DIAGNOSIS of PRIMARY HYPERPARATHYROIDISM.
Ann Endocrinol (Paris)

The differential diagnosis of primary hyperparathyroidism can be considered clinically, biologically and radiologically. Clinically, primary hyperparathyroidism should be suspected in case of diffuse pain, renal lithiasis, osteoporosis, repeated fracture, cognitive or psychiatric disorder, or disturbance of consciousness. Nevertheless, the differential diagnosis of primary hyperparathyroidism is mainly biological, particularly in atypical forms, which must be differentiated from hypercalcemia with hypocalciuria or non- elevated PTH on the one hand, and from normo-calcemia with elevated PTH, hypophosphatemia or hypercalciuria on the other.

River quality management involves complex challenges due to inherent uncertainties in various parameters, especially when dealing with controllable and uncontrollable pollutants. This study integrates a finite volume approach, called SEF (symmetric exponential function), with Monte Carlo simulations in MATLAB to solve the advection-dispersion equation, focusing on evaluating river quality protection tools by considering failure probability (P). Critical specifications for maintaining reliable river ecosystem performance are identified.

Cryopreservation of rooster semen is a reproductive technology carried out to boost genetic gain and productivity in commercial flocks of chicken. However, semen freezing significantly reduces the quality and fertilizing potential of spermatozoa. This study examined cryoprotective effects of the mitochondria-targeted antioxidant mitoquinol mesylate added to the freezing extender by assessing post-thaw characteristics of rooster sperm.

Background: Joubert syndrome (JS) is an autosomal recessive disorder with a distinctive mid-hindbrain malformation known as the "molar tooth sign" which involves the breathing control center and its connections with other structures. Literature has reported significant respiratory abnormalities which included hyperpnea interspersed with apneic episodes during wakefulness. Larger-scale studies looking at polysomnographic findings or subjective reports of sleep problems in this population have not yet been published.

Type II restriction-modification (R-M) systems play a pivotal role in bacterial defense against invading DNA, influencing the spread of pathogenic traits. These systems often involve coordinated expression of a regulatory protein (C) with restriction (R) enzymes, employing complex feedback loops for regulation. Recent studies highlight the crucial balance between R and M enzymes in controlling horizontal gene transfer (HGT).
