A new pattern of morphofunctional relationship among cranial nerves: Evidence of anatomical and physiological connection between trigeminus and oculomotor nerves     

R. Bortolami  E. Callegari  M. L. Lucchi 《Veterinary research communications》1977,1(1):27-32

It is shown that the cell bodies of the afferent fibres supplying the proprioceptivity to the extrinsic eye muscles are located within the semilunar ganglion. Furthermore, some Gasserian cells have central processes which enter the midbrain through the oculomotor nerve. Sensory ganglion cells, derived from the same strand of placodal cells forming the ophthalmic lobe, can be constantly detected within the oculomotor nerve of ox, monkey and man.

Kurzfassung Unsere Forschungen haben ergeben, dass sich die Zellkörper der fibrae afferentes, die dem äusserlichen Augenmuskeln die propriozeptive Sensibilität geben, im Ganglion des Gasser befinden. Ausserdem haben einige Zellen des Gasserschenganglion zentrale Verzweigungen die durch den Nervus oculomotorius in den Hirnstamm führen. Sensitive Ganglionzellen, die von der gleichen Reihe plakodischer Zellen stammen, und den lobus oftalmicus Gasseri formen, sind regelmassig im nervus oculomotorius des Rindes, des Affen und des Menschen zu finden.

Resume Nos recherches ont démontré que, chez le Mouton et le Porc, le ganglion de Gasser contient les corps cellulaires des fibres nerveuses desservant les fuseaux neuromusculaires des muscles extrinsèques de l'oeil. En outre, quelques cellules du ganglion de Gasser ont leurs prolongements centraux qui se portent au tronc cérébral en suivant à rebours les radicules du nerf oculomoteur. En fin, on a trouvé constamment des cellules ganglionnaires sensitives dans l'oculomoteur du Boeuf, du Singe et de l'Homme; ces cellules proviennent du même cordon de cellules placodiales qui forme le lobe ophthalmique du ganglion semilunaire.

Riassunto Le nostre ricerche hanno dimostrato che i corpi cellulari delle fibre nervose afferenti, che danno la sensibilità propriocettica al muscolo oculare estrinseco, si trovano nel ganglione di Gasser. Inoltre, alcune cellule del ganglione di Gasser hanno diramazioni centrali che portano al tronco cerebrale attraverso il nervo oculomotore. Infine, si sono costantemente incontrati nel nervo oculomotore del bovino, della scimmia e dell'uomo, cellule sensitive che provengono dallo stessotronco di cellule placodali che formano il lobo oftalmico.

Effects of adding different concentrations of melatonin (10^?7, 10^?9 and 10^?11 M) to maturation (Experiment 1; Control, IVM  + 10^?7, IVM  + 10^?9, IVM  + 10^?11) and culture media (Experiment 2; Control, IVC  + 10^?7, IVC  + 10^?9, IVC  + 10^?11) were evaluated on in vitro bovine embryonic development. The optimal concentration of melatonin (10^?9 M) from Experiments 1–2 was tested in both maturation and/or culture media of Experiment 3 (Control, IVM  + 10^?9, IVC  + 10^?9, IVM /IVC  + 10^?9). In Experiment 1, maturated oocytes from Control and IVM  + 10^?9 treatments showed increased glutathione content, mitochondrial membrane potential and percentage of Grade I blastocysts (40.6% and 43%, respectively). In Experiment 2, an increase in the percentage of Grade I blastocysts was detected in IVC  + 10^?7 (43.5%; 56.7%) and IVC  + 10^?9 (47.4%; 57.4%). Moreover, a lower number and percentage of apoptotic cells in blastocysts were observed in the IVC  + 10^?9 group compared to Control (3.8 ± 0.6; 3.6% versus 6.1 ± 0.6; 5.3%). In Experiment 3, the IVC  + 10^?9 treatment increased percentage of Grade I blastocysts with a lower number of apoptotic cells compared to IVM /IVC  + 10^?9 group (52.6%; 3.0 ± 0.5 versus 46.0%; 5.4 ± 1.0). The IVC  + 10^?9 treatment also had a higher mRNA expression of antioxidant gene (SOD 2) compared to the Control, as well as the heat shock protein (HSPB 1) compared to the IVM  + 10^?9. Reactive oxygen species production was greater in the IVM /IVC  + 10^?9 treatment group. In conclusion, the 10^?9 M concentration of melatonin and the in vitro production phase in which it is used directly affected embryonic development and quality.  相似文献   

Molecular markers for improving control of soil-borne pathogen <Emphasis Type="Italic">Fusarium oxysporum</Emphasis> in sugar beet     

Chiara De Lucchi  Piergiorgio Stevanato  Linda Hanson  Mitch McGrath  Lee Panella  Marco De Biaggi  Chiara Broccanello  Marco Bertaggia  Luca Sella  Giuseppe Concheri 《Euphytica》2017,213(3):71

Fusarium spp. cause severe damage in many agricultural crops, including sugar beet, with Fusarium oxysporum historically being considered as the most damaging of all species. Sugar beet needs to be protected from this class of soil-borne pathogens in order to ensure an optimal sugar yield in the field. Genetic control of the disease is crucial in managing these pathogens. Identification of single nucleotide polymorphism (SNP) markers linked to resistance can be a powerful tool for the introgression of valuable genes needed to develop Fusarium-resistant varieties. A candidate gene approach was carried out to identify SNP markers linked to putative Fusarium resistance sources in sugar beet. Five resistant analogue genes (RGAs) were screened by means of high resolution melting (HRM) analysis in a set of sugar beet lines, considered as resistant and susceptible to Fusarium oxysporum. HRM polymorphisms were observed in 80% of amplicons. Two HRM polymorphisms were significantly associated with Fusarium resistance (P < 0.05). The amplicons that showed association were sequenced and two SNPs were identified. The association was further validated on 96 susceptible and 96 resistant plants using competitive allele-specific PCR (KASPar) technology. The selected SNPs could be used for marker-assisted breeding of Fusarium resistance in sugar beet.  相似文献   

Artificial Insemination of Gilts with 1.5 Billion Sperms Stored in Different Periods Associated with Different Pre-ovulatory Intervals     

PE Bennemann  GN Diehl  E Milbradt  RM Vidor  HCC Fries  I Wentz  ML Bernardi  FP Bortolozzo 《Reproduction in domestic animals》2005,40(6):507-510

This study evaluated the reproductive performance of gilts inseminated at three intervals before ovulation (0-12, 13-23, 24-30 h) with sperm doses (SD) stored for 0-48 and 96-120 h. A total of 218 PIC Camborough 22 gilts were inseminated once with SD of 1.5 x 10(9) sperms. Pregnant gilts (n = 166) were slaughtered 30.8 +/- 3.7 days after artificial insemination. The number of corpora lutea (CL) and total embryos (TE) was counted. Pregnancy rates (PR) were analysed by chi-square test. TE and embryonic survival (ES), obtained as the ratio between viable embryos and CL, were analysed by GLM procedure (SAS) and mean values were compared by Tukey's test. Pregnancy rate was similar among artificial insemination-ovulation (AIOV) intervals when semen was stored for 0-48 h. However, the lowest PR was observed in the 24-30 h AIOV interval with storage time (ST) of 96-120 h (p < 0.05). There was a significant effect of the interaction between ST and AIOV (p < 0.05) on TE and ES variables. Total embryos and ES did not differ (p > 0.05) among AIOV intervals in ST of 0-48 h. However, gilts inseminated at 24-30 h AIOV interval with ST of 96-120 h showed a reduction of 6.7 embryos (p < 0.05) compared with gilts in the same interval inseminated with semen stored for 0-48 h. ES for the 24-30 h AIOV interval and ST of 96-120 h was lower than that observed in the other groups (p < 0.05).  相似文献
