City willing to comply to new loan rules says Guardiola

first_imgManchester City Pep Guardiola says the club will definitely comply if directed to reduce the number of loaned out players.According to reports, FIFA are considering to set the number of outgoing player loans allowed for each club to a maximum of between 6 and 8, from the start of the 2020-21 season, and Guardiola believes the club will have no problem adapting to the rule.Manchester City currently have 28 players on loan spells in different clubs all over Europe.Big clubs have been accused of stockpiling players that they could later sell for profit and thereby abusing the loan system which was meant to be used for player development.“We are going to adapt to the rules,” Guardiola told Sky Sports.“The new rules are coming. We’re going to see the situation about loan players and see what we can do.norwich city, manchester city, premier leagueReport: City are stunned by Norwich George Patchias – September 14, 2019 Manchester City was stunned by Norwich City in todays Premier League clash.Much has been made in recent days of the potential impact of Aymeric…“If we cannot loan them they are going to come back here. If we don’t believe they are going to play, if we cannot loan them, we are going to sell them. It’s simple.“We’re going to see before they take the players where they are going to play and if it is not possible to loan them we are not going to buy them.”Guardiola thinks the Under-23 competition in England is not enough preparation for players hoping to make it in the Premier League, as he supports the loan system.“It’s not good for me,” Guardiola added.“Loan players are in good leagues. To then come here to play in front of 10 people is not good for their development.”last_img read more

Credit: Scientific Reports, doi: https://doi.org/10.1038/s41598-018-36742-0 By nature, the craniofacial complex contains three distinct regions: the skull vault, cranial base and the face. The cranial base forms the floor of the braincase and the skull vault – the roof. Bones of the cranial base form via endochondral ossification, while osteogenesis in the skull vault occurs via intramembranous ossification. Both the skull vault and cranial base are of embryonic origin (neural-crest derived or mesodermally derived). Embryological study of the skull reveals dinosaur-bird connection In contrast, in the homozygous mutant (PrickleBJ/BJ), contributions of the frontal bone to the total length increased, while the proportion of the parietal bone remained unchanged. Taken together, the results indicated that the Prickle1 protein function was required during all stages of frontal bone development. Wan et al. focused on the function of Prickle1 in the developing skull vault by examining the tissue distribution of the protein in wild type vs. mutant embryos. They found that the Prickle1 mutation resulted in two defected processes during frontal bone development, which included delayed osteoblast differentiation and reduced migration in the frontal bone. Such frontal bone defects were also observed in the phenotypic spectrum of cleidocranial dysplasia (CCD). The observed frontal bone insufficiency could potentially result from defects in proliferation and cell death. The scientists conducted studies using Haematoxylin and Eosin (H&E) histology dyes to test the hypothesis by observing frontal bone condensation in the wild type vs. mutant animals at embryonic stage 12.5 (E12.5), at which time frontal bone condensation typically occurred. Thereafter, they conducted TUNEL apoptosis assays, where the results indicated very few apoptotic cells (depicted via TUNEL positive uptake) in either genotype. Wan et al. further determined if a defective signaling system led to the observed delayed frontal bone osteogenesis by studying the level of canonical Wnt and Hedgehog (HH) signaling in the mutants. The results suggested that the levels of HH signaling (required for cranial bone development) were, indeed, defective in the mutant animals. Finally, they conducted in situ hybridization to markers of osteoblast migration (with markers Engrailed1 (En1), Twist1, Msx1 and Msx2) in the wild type and mutant littermates. The expression level of the markers was reduced in the frontal bone primordia in the mutants. The results suggested the Prickle1 protein function was necessary to mediate cell migration of osteoblast precursors during all stages of skull vault development. In this way, Wan et al. analyzed the Beetlejuice mutant mouse as a new model to understand the etiology of microcephaly. The number of animal models currently in use to determine the growth patterns of the face and skull in microcephaly are limited. The scientists combined genetic, molecular and physical mechanisms in the study relative to Prickle1 mutants to show contributions to decreased growth of the craniofacial region in the new mouse model. Wan et al. will continue the work to understand how cell migration and the alteration of each compartment (brain, skull vault and cranial base) contribute to the development of microcephaly, clavarial patterning and growth.

The Wnt/Planar cell polarity signaling pathway (Wnt/PCP), usually regulates cell migration and movement in tissues during embryonic development. In a recent study, conducted by Yong Wan and colleagues at the Center for Craniofacial Regeneration, the central research emphasis was on the Prickle1 gene, a core component of the Wnt/PCP pathway, in the skull.

DOI: 10.1016/S0092-8674(00)80260-3 The study included BrdU-labelled cell counts in the mutant vs. wild type mice to show no difference in the ratio of proliferating cells either. The number of actively dividing cells were then tested using phosphor-histone H3 immunohistochemistry to show no difference in the number of dividing cells in littermates. Since there was no change in cell death and proliferation, the scientists were next determined to test if osteogenic differentiation was occurring correctly.For this, Wan et al conducted RNA in situ hybridization experiments to assess the expression of alkaline phosphatase (ALP) and Osterix (OSX, also known as Sp7) in the pre-osteoblasts and osteoblasts of the frontal bones. They determined the expression of RUNX2, an early marker of osteoblast commitment in the skull and of ALP, a marker of more mature osteoblasts. By embryonic stage 15.5 (E15.5), the expression of Runx2, ALP and OSX decreased in the ectocranial layer of the mutant frontal bones compared with wild type littermates. The scientists determined that intramembranous ossification (conversion of mesenchymal tissue into bone) delayed in the frontal bone results in the hypoplastic Beetlejuice mutants. , Cell No change in the rate of proliferation or apoptosis in the Prickle1Bj/Bj frontal bones. At embryonic stage 12.5 (E12.5), Prickle1+/+ (a–d) and Prickle1Bj/Bj (f–i) littermates assayed for histology (haemotoxylin and eosin) staining (a,f), TUNEL staining (b,g), proliferation with BrdU immunofluorescence (c,h) and mitosis with phospho-histone H3 immunohistochemistry (d,i). (a,d) The frontal bone mesenchymal condensation (black outline) is present in both wildtype (a) and Prickle1Bj/Bj (f) littermates. (b,g) TUNEL-positive cells were found near the eye (arrowheads) and absent in the frontal bone primordia.

Credit: Scientific Reports, doi: https://doi.org/10.1038/s41598-018-36742-0 For the studies, Wan et al. used the missense allele of Prickle1, named Prickle1Beetlejuice (PrickleBJ). The homozygous PrickleBJ/BJ ‘Beetlejuice’ mutants were microcephalic and developed enlarged fontanelles between insufficient frontal bones, although the parietal bones were normal. The homozygous mutants had several other craniofacial defects including a midline cleft lip, incompletely penetrant cleft palate and decreased proximal-distal growth of the head. The scientists observed decreased Wnt/β-catenin and hedgehog signaling in the frontal bone condensations of the homozygous mutants in the study.The results are now published on Scientific Reports. In the homozygous mutants, the frontal bone osteoblast precursors underwent delayed differentiation, alongside decreased expression of migratory markers, resulting in underdeveloped frontal bones. The study showed that the Prickle1 protein function contributed to both migration and differentiation of bone-forming cells (osteoblast precursors) and its absence in the mutant animal model resulted in the defects. The homozygous mutants (PrickleBJ/BJ) developed cardiac outflow tract misalignment and cleft palate, contributing to perinatal death of the mutant mice. Therefore, the observed phenotypic features were from early to late embryonic stages. , Journal of Bone and Mineral Research In the study model, the Beetlejuice mutants (Bj) contained a point-mutation in the Prickle1 gene (C161F), the Bj C161F mutation was deleterious to the function of the cytoplasmic protein Prickle1. Mutations of the protein in humans are usually associated with familial epilepsy. The mutant phenotype was consistent with another independent point mutation of Prickle1, known as C251X, which included stunted limbs and a cleft palate. While the protein product of the gene is widely expressed in the cytoplasm, little was known about its role in craniofacial osteogenesis. In the present study, Wan et al. analyzed the bones and cartilage of the head using alcian blue and alizarin red histology dyes. The homozygous mutant skulls were smaller, and the proximal-distal length of the head was reduced with an increased medial-lateral width of the skull. The results showed a statistically significant decrease in the contribution of the nasal bone to the total length of the skull vault in the wild type mice (Prickle+/+).
