Subjecting a physical system to extreme conditions is one of the means often used obtain better understanding and deeper insight into its organization structure. In case atomic nucleus, such approach investigate isotopes that have very different neutron-to-proton (N/Z) ratios than in stable nuclei. Light, neutron-rich exhibit most asymmetric N/Z those lying beyond limits binding, which undergo spontaneous neutron emission exist only as short-lived resonances (about 10-21 s), provide...
The key parameter to discuss the possibility of pion condensation in nuclear matter, i.e., so-called Landau-Migdal g^{'}, was extracted by measuring double-differential cross sections for (p,n) reaction at 216 MeV/u on a neutron-rich doubly magic unstable nucleus, ^{132}Sn with quality comparable data taken stable nuclei. strengths Gamow-Teller (GT) transitions from leading ^{132}Sb exhibit GT giant resonance (GTR) excitation energy 16.3±0.4(stat)±0.4(syst) MeV width Γ=4.7±0.8 MeV....
Detailed spectroscopy of the neutron-unbound nucleus $^{28}\mathrm{F}$ has been performed for first time following proton/neutron removal from $^{29}\mathrm{Ne}/^{29}\mathrm{F}$ beams at energies around $230\text{ }\text{ }\mathrm{MeV}/\mathrm{nucleon}$. The invariant-mass spectra were reconstructed both $^{27}{\mathrm{F}}^{(*)}+n$ and $^{26}{\mathrm{F}}^{(*)}+2n$ coincidences revealed a series well-defined resonances. A near-threshold state was observed in reactions is identified as ground...
The last proton bound calcium isotope $^{35}\mathrm{Ca}$ has been studied for the first time, using $^{37}\mathrm{Ca}(p,t)^{35}\mathrm{Ca}$ two neutron transfer reaction. radioactive $^{37}\mathrm{Ca}$ nuclei, produced by LISE spectrometer at GANIL, interacted with protons of liquid hydrogen target CRYPTA, to produce tritons $t$ that were detected in MUST2 detector array, coincidence heavy residues Ca or Ar. atomic mass and energy its $3/{2}^{+}$ state are reported. A large $N=16$ gap...
This paper reports on new \(B\)(E2) values for \(^{36}\)Si and \(^{38}\)Si obtained by Coulomb excitation at GANIL during the LISE 2022 campaign. The results agree well with shell model calculations confirm increase in proton neutron excitations neutron-rich Si isotopes towards \(N=28\). experiment was performed a “brochette” mode together ACTAR TPC to measure simultaneously inelastic scattering.

Lenvatinib is an oral multitargeted tyrosine kinase inhibitor that has anticancer action in patients with differentiated thyroid cancer refractory to radioiodine. Knowledge of the efficacy and safety lenvatinib anaplastic (ATC) limited. Tyrosine inhibitors frequently cause hypothyroidism, but incidence hypothyroidism unclear.We conducted a retrospective study investigate ATC.Five unresectable ATC were enrolled. 24 mg once daily was administered until disease progression, unmanageable...
Primary squamous cell carcinoma (SCC) in the thyroid is extremely rare and has been reported < 1% of all cancer cases. SCC was thought to be a transitional form derived from adenocarcinomas; therefore, majority cases have focused on conjunction with other histological adenocarcinomas. A 73-year-old male presented our hospital bilateral vocal fold palsy an anterior neck mass. Ultrasound sonography revealed bulky tumor cervical lymphadenopathy. We performed fine-needle aspiration...
<b><i>Background:</i></b> Anaplastic thyroid carcinoma has an extremely poor prognosis, and no known drugs have exhibited acceptable efficacy. In recent years, novel anticancer tyrosine kinase inhibitors been developed. We encountered a case of tracheal stenosis due to mediastinal infiltration anaplastic for which lenvatinib remarkable effects; owing this, airway management could be performed, even though the patient’s condition was considered critical....
Piriform sinus fistula (PSF) is a rare branchial anomaly that causes repetitive acute suppurative thyroiditis or deep neck abscess. The definitive treatment of PSF open surgery. However, such surgery has cosmetic problem and high risk recurrence. Furthermore, identifying the difficult due to previous infections. We report case esophageal submucosal abscess caused by treated with endoscopic mucosal incision. patient underwent transoral video laryngoscopic (TOVS), endoscopy as well fluoroscopy...
Acoustic radiation force impulse (ARFI) imaging is a recent ultrasound elastography technique; consequently, its efficacy not fully known. In this study, we compared ARFI with conventional strain (SE) and shear wave velocities (SWVs) to evaluate the utility of for diagnosing thyroid nodules.In study examined 233 nodules (183 benign 50 malignant nodules) isolated from human patients. The were evaluated SE imaging, SWVs simultaneously measured. images classified using four-point score based on...
The spallation and fragmentation reactions of Xe136 induced by proton, deuteron, carbon targets at 168 MeV/nucleon were studied RIKEN Radioactive Isotope Beam Factory via the inverse kinematics technique. A wide range isotopic distributions reaction cross sections has been obtained systematically analyzed using Particle Heavy Ion Transport code System (PHITS) including dynamical intranuclear cascade processes plus evaporation process, semi-empirical parametrization for residue in (SPACS)...
The nucleus $^{29}$Ne is situated at the border of island inversion. Despite significant efforts, no bound low-lying intruder $f_{7/2}$-state, which would place firmly inside inversion, has yet been observed. Here, first investigation unbound states reported. were populated in $^{30}\mathrm{Ne}(p,pn)$ and $^{30}\mathrm{Na}(p,2p)$ reactions a beam energy around $230$ MeV/nucleon, analyzed terms their resonance properties, partial cross sections momentum distributions. distributions are...
We present an adult case of mumps brains tern encephalitis. He was successfully treated with steroid pulse therapy and recovered completely except for persistent dysuria. had not been vaccinated no history acute infection. consider that encephalitis in this caused by a reversible autoimmune process triggered emphasize the usefulness treatment some cases brainstem addition to importance vaccination prevent such severe complication as encephalitis.(Internal Medicine 39: 499-502, 2000)
Abstract The spin-isospin responses of the 11 Li drip-line nucleus has been measured. Preliminary results Li( p, n ) Be experiment in inverse kinematics at RI Beam Factory (RIBF) RIKEN Nishina Center are presented including observation 1 , 2 n, t, d α and 6 He+ decay channels reaction product. Details experimental setup based on PANDORA (Particle Analyzer Neutron Detector Of Real-time Acquisition) low-energy neutron detector SAMURAI large-acceptance magnetic spectrometer described.
Within the SEASTAR project at RIKEN-RIBF, 66Cr and 70,72Fe have been produced via protonknockout reactions, their first excited 2+ 4+ states discovered. The combination of liquid-hydrogen target TPC system MINOS has used in with DALI2 detector array for time. A 345 MeV/u 238U beam a mean intensity about 12 pnA impinged on Be target. Fission fragments were separated identified using BigRIPS spectrograph, reaction products analyzed ZeroDegree spectrograph. plateau excitation energies, small...
