A 1.8 kg, seven months old, intact, female, mix-breed cat was referred with dyspnea and paresis. Since the patient was in such a condition that she was too incapable of the operation, treatment for dyspnea was performed. The patient has abdominal enlargement. When the respiratory stress of the patient decreased, a radiograph was taken and lordosis was found. Medical treatment was applied, because the general condition was impaired. Lordosis is the excessive curvature of a certain number of vertebrae in the neck and back region. Congenital thoracic lordosis has been described as a highly progressive and low vital capacity disease in humans and cats. Because it compresses the lung, it can cause dyspnea in patients and rhythm disturbances in the heart. This case represents a severe example of untreatable and unmanageable lordosis encountered in a cat.

Recently, the space bvp of real or complex numbers consisting of all sequences whose differences are in the space lp has been studied by basar, Altay [Ukrainian Math. J. 55（1）（2003）, 136-147], where 1 ≤ p ≤ ∞. The main purpose of the present paper is to introduce the space bvp（F） of sequences of p-bounded variation of fuzzy numbers. Moreover, it is proved that the space bvp（F） includes the space lp（F） and also shown that the spaces bvp（F） and lp（F） axe isomorphic for 1 ≤ p ≤∞. Furthermore, some inclusion relations have been given.

Using the light-cone QCD sum rules,we evaluate the magnetic moment of the P_c(4312) pentaquark state by considering both the \bar D\Sigma_c molecular and diquark-diquark-antiquark state,with quantum numbers J^P=2/1^(-1).In the calculations,we use the diquark-diquark-antiquark and molecular form of the interpolating currents for the P_(c4312) pentaquark and the distribution amplitudes of the *** numerical results for the magnetic moment obtained using the two different pictures are quite different from each other,which can be used to pin down the underlying structure of P_(c4312) .Any experimental measurement of the magnetic moment in the near future will provide an understanding of the internal structure of this pentaquark state.

This paper explains that the terms“horizontal and vertical scales”are not appropriate in map projections ***,the authors suggest using the term“scales in the direction of coordinate axes.”Since it is not possible to read a local linear scale factor in the direction of a coordinate axis immediately from the definition of a local linear scale factor,this paper considers the derivation of new formulae that enable local linear scale factors in the direction of coordinate x and y axes to be *** formula for computing the local linear scale factor in any direction defined by dx and dy is also ***,the position and magnitude of the extreme values of the local linear scale factor are considered and new formulas derived.

The patient was admitted to OndokuzMayıs University Animal Hospital Internal Medicine outpatient clinic with complaints of epileptic seizures and hypothyroidism. A description of the patient’s owner is available in the history information. There was no physician information. Bradycardia was found in the electrocardiography of the patient. 2-D, M-Mode, PW, CW and Color doppler examinations were performed. Left-ventricular hypokinetic and mitral and tricuspidal valve movements were observed with limited M-Mode imaging. Anterior mitral orifice of 2 mm width was detected on septal mitral valve by PW doppler and color doppler. With this orifice, the presence of regurgitant jet, which covers LA at a rate of 1/3 and was 3.2 m/sec, together with mitral regurgitation (0.5 m/sec.), was demonstrated. PISA calculations;VFR (mL/s), ERO (mm2) and RVol (mL/pulse) values were calculated as if there were mitral regurgitation and data were obtained for mild-moderate mitral regurgitation. Therefore, no operative treatment of the orifice was recommended. Mitral valve orifice is a rare pathology and this is the first report in canine veterinary practice with degenerative mitral valve disorder. We aimed to underline the possibility of mitral orifice development in degenerative mitral valve disorders, known to present with vegetations and varying degrees of prolapsus, conventionally.

baCKGROUND： An emergency department （ED） visit may be distressing and anxiety-provoking for older adults （age 〉 65 years）. No studies have specifically evaluated the effect of music listening on anxiety in older adults in the ED. OBJECTIVE： The objective of this pilot study was to evaluate the effect of music listening on anxiety levels in older ED patients. DESIGN, SETTING, ParTICIPANTS AND INTERVENTIONS： This was a randomized pilot study in the geriatric ED of an urban academic tertiary medical center. This was a sample of English-speaking adults （age 〉 65 years） who were not deaf （n = 35）. Subjects consented to participate and were randomized to receive up to 60 min of music listening with routine care, while the control group received routine care with no music. Subjects in the music treatment group received headphones and an electronic tablet with pre-downloaded music, and were allowed to choose from 5 selections. MAIN OUTCOME MEASURES： The primary outcome was change in anxiety levels, measured by the state- trait anxiety inventory （STAI）, at enrollment and 1 h later. RESULTS： A total of 35 participants were enrolled： 74% were female, 40% were white, and 40% were black; of these, 32 subjects completed the study protocol. When comparing control （n = 18） against intervention subjects （n = 17）, there were no significant differences in enrollment STAI scores （43.00 ± 15.00 vs. 40.30± 12.80, P = 0.57）. STAI scores 1 hour after enrollment （after the music intervention） were significantly reduced in the intervention subjects compared to the control subjects （with reduction of 10.00± 12.29 vs. 1.88 ± 7.97, P = 0.03）. CONCLUSION： These pilot results suggest that music listening may be an effective tool for reducing anxiety among older adults in the ED.
