No causal treatment for chemotherapy‐induced peripheral neuropathy (CIPN) is known. Therefore, there is an urgent need to develop a therapy for CIPN. Only scarce clinical data are available concerning magnetic field therapy (MFT) in this context. We conducted a unicentric, randomized, double‐blind, placebo‐controlled phase‐III trial of an MFT device versus placebo. In this study, we randomized 44 patients with CIPN to two treatment groups, where 21 patients were treated with MFT (Group 1) and 23 patients received placebo (Group 2). We evaluated the efficacy of MFT at baseline (T1), after 3 weeks of study treatment (T2), and after 3 months of study treatment (T3). The primary endpoint was nerve conduction velocity (NCV), while secondary endpoints were the Common Toxicity Criteria (CTCAE) score and the Pain Detect End Score at T3. Seventeen of the patients in Group 1 and 14 patients in Group 2 completed the respective study treatment. The primary endpoint, significant improvement of NCV at T3, was achieved by MFT (P = 0.015), particularly for sensory neurotoxicity of the peroneal nerve. Also, in respect to the secondary endpoints, significant improvement (P = 0.04) was achieved in terms of the patients’ subjectively perceived neurotoxicity (CTCAE score), but not of neuropathic pain (P = 0.11). From data in the randomized study presented here, a positive effect on the reduction of neurotoxicity can be assumed for the MFT device. Patients with sensory neurotoxicity in the lower limbs, especially, should therefore be offered this therapy. Bioelectromagnetics. 38:85–94, 2017. © 2016 The Authors.

Freezing tolerance/intolerance and cryoprotectant synthesis in terrestrially overwintering anurans in the Great Plains,USA 总被引:2,自引:0,他引:2

Mechanistic bases for freezing tolerance in anurans have been well-studied only in wood frogs, Rana sylvatica, so comprehensive explanations for the mechanisms and evolution of freezing tolerance in anurans are lacking. We measured crystallization temperatures, freezing tolerance/intolerance, and tissue glucose and glycogen phosphorylase activities in frozen and unfrozen winter-acclimated Pseudacris triseriata, Bufo cognatus and B. woodhousei. Freezing occurred at higher subzero temperatures on wet substrate than on dry substrate in all species, indicating susceptibility to inoculative freezing. P. triseriata was freeze-tolerant, but survival was dependent on the level of supercooling prior to freezing. All Bufo were freezing intolerant, regardless of crystallization temperature. Glucose was significantly elevated by freezing in both liver (35-fold) and leg muscle (22-fold) in winter P. triseriata, but only liver glucose was significantly elevated in B. cognatus. However, freezing did not alter glycogen phosphorylase activity in either species. Liver phosphorylase activity was significantly higher in P. triseriata than in B. cognatus, suggesting that capacity for mobilizing glucose from liver glycogen is associated with freezing tolerance. Summer measurements of liver phosphorylase activity, however, did not differ between species. Thus, P. triseriata, but not B. cognatus, exhibited winter increment of liver phosphorylase activity that is correlated with the development of freezing tolerance.Abbreviation

During cold acclimation by higher plants, temperature perception via changes in redox state of Photosystem II (PSII) and subsequent
acclimation of the photosynthetic apparatus to cold is very important for achieving freezing tolerance. These properties were
studied in two groups (A and B) of the same backcross 3 (BC3) progeny derived from a triploid hybrid of Festuca pratensis (2×) × Lolium multiflorum (4×) backcrossed three times onto diploid L. multiflorum cultivars. Leaves of Group A plants formed at 20°C at medium-low light were unable to acclimate their photosynthetic apparatus
to cold. Compared to Group B, the Group A plants were also more frost sensitive. This acclimation ability correlated with
the freezing tolerance of the plants. However, leaves of the same Group A plants developed at 20°C, but under higher-light
conditions had increased ability to acclimate their photosynthetic apparatus to cold. It was concluded that Group A plants
may have impaired PSII temperature perception, and this then resulted in their poor capability to cold acclimate. 相似文献

In experiments using cryosurgical apparatus to freeze the canine palate in situ, observations were made on techniques of producing tissue destruction. Several time-temperature schedules of freezing were studied. The results showed the great tolerance of palatal tissues to extremely low temperatures for short time periods. Melanocytes were extraordinarily sensitive to cold injury. Tissue necrosis increased with duration of freezing, but repeated freezing was lethal and obviously critical for successful cryosurgical destruction. Thermocouples must be used in clinical cryosurgery to insure that lethal tissue temperatures (colder than ?50 °C) are attained. The incidence of sequestration in the canine palate showed the need for use of proper technique and suitable precautions in the cryosurgical treatment of human palatal tumors. 相似文献

The objective of this study was to assess the effect of an elevated atmospheric CO2 molar ratio on freezing tolerance, photosynthetic apparatus performance and expression of CBF6, Cor14b and LOS2 in meadow fescue (Festuca pratensis Huds.). It was shown that cold acclimation under a CO2 molar ratio of 800 μmol mol(air)?1 decreased the freezing tolerance of meadow fescue when compared to the ambient CO2 level. This effect was not related either to changes observed in PSII redox state or to photosynthetic acclimation to cold, which was in fact more effective at an elevated CO2 level. The decrease in freezing tolerance was linked to changes in the expression of CBF6 and LOS2 genes, whereas the protective effect on photosynthetic apparatus was connected with the activation of a non-photochemical mechanism of photoprotection as well as upregulation of FpCOR14b expression. 相似文献

Rationale
The endurance time (Tend) during constant-workrate cycling exercise (CET) is highly variable in COPD. We investigated pulmonary and physiological variables that may contribute to these variations in Tend.Methods
Ninety-two patients with COPD completed a CET performed at 80% of peak workrate capacity (Wpeak). Patients were divided into tertiles of Tend [Group 1: <4 min; Group 2: 4–6 min; Group 3: >6 min]. Disease severity (FEV1), aerobic fitness (Wpeak, peak oxygen consumption [ peak], ventilatory threshold [ VT]), quadriceps strength (MVC), symptom scores at the end of CET and exercise intensity during CET (heart rate at the end of CET to heart rate at peak incremental exercise ratio [HRCET/HRpeak]) were analyzed as potential variables influencing Tend.Results
Wpeak, peak, VT, MVC, leg fatigue at end of CET, and HRCET/HRpeak were lower in group 1 than in group 2 or 3 (p≤0.05). VT and leg fatigue at end of CET independently predicted Tend in multiple regression analysis (r = 0.50, p = 0.001).Conclusion
Tend was independently related to the aerobic fitness and to tolerance to leg fatigue at the end of exercise. A large fraction of the variability in Tend was not explained by the physiological parameters assessed in the present study. Individualization of exercise intensity during CET should help in reducing variations in Tend among patients with COPD. 相似文献9.
Magnetic resonance imaging (MRI) of water during cold acclimation and freezing in winter wheat 总被引:4,自引:2,他引:2
Nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI) were used to analyse changes in the physical state of water in wheat crowns during cold acclimation and during the freezing/thawing cycle. Spectroscopically measured average spin-spin relaxation times (T2) decreased during cold acclimation and increased when plants were grown at normal temperature. Spin-spin relaxation images whose contrast is proportional to T2, times were calculated allowing association of water relaxation with regions of tissue in spin-echo images during acclimation and freezing. Images taken during freezing revealed nonuniform freezing of tissue in crowns and roots. Acclimated and non-acclimated wheat crowns were imaged during freezing and after thawing. Spin-echo image signal intensity and T2 times decreased dramatically between -4°C and -8°C as a result of a decrease in water mobility during freezing. Images collected during thawing were diffuse with less structure and relaxation times were longer, consistent with water redistribution in tissue after membrane damage. 相似文献

Seasonal changes in the physical state of crown water associated with freezing tolerance in winter wheat 总被引:9,自引:0,他引:9

The relationship between freezing tolerance (expressed as LT50, the lethal freezing temperature for 50% of plants) and the amount and physical state (as determined by spin-lattice [T1] and spin-spin [T2] relaxation times of protons) of water in crown tissue was examined in contrasting winter wheat (Triticum aestivum L.) varieties grown under field conditions from 1992 to 1994. During acclimation, the LT50 values decreased from around -7 to -17, -20 and -27°C in PI 173438, Chihokukomugi and Valuevskaya, respectively. Tissue water content decreased continuously through autumn to reach a plateau around 3 g H2O (g dry weight)-1 in early winter when LT50 was still decteasing, and then gradually increased under snow cover. A significant negative correlation was found between mean minimum air temperatures and freezing tolerance prior to the establishment of continuous snow cover. In contrast, a positive association between mean minimum temperatures and crown tissue water content was significant only when air temperatures were above 0°C, as water content did not decrease further at sub-zero temperatures. Seasonal changes in T1 were closely related to changes in freezing tolerance. T1 decreased until January even though water content stopped decreasing. Further tests on 15 field-grown varieties confirmed a strong negative association between freezing tolerance and T1. The results suggest that cold hardening is comprised of two stages, with the transition occurring at ca 0°C. Development of hardiness was related to (1) a reduction in water content in the first stage (at minimum temperatures > 0°C), and (2) a change in physical state of water without much reduction in water content in the second stage. Varietal differences in hardiness thus arise due to changes in both water content and physical state of water. 相似文献

An aggregated sample of 925 Atlantic cod Gadus morhua collected by four countries in different regions of the Baltic Sea during different seasons were measured (total length, LT = 161–890 mm and weighed (mass, M = 45–6900 g) both before freezing and after defrosting. The cod were found to decrease significantly in both LT and M following death and frozen storage. There was an average (±SD) change in LT of −2.91% (±0.05%) following freezing, independent of starting LT. Total M changed by −2.65% (±0.14%), independent of starting mass. Shrinkage of LT and M did not differ significantly between 1 and 4 months frozen storage, though LT shrinkage was significantly greater after 1 or 4 months in the freezer compared with after 5 days. There was significant variation in LT and M shrinkage between regions of capture. A significant negative relationship between condition of cod and LT or M change was also observed. Equations to back-calculate fresh LT and M from thawed LT, M and standard length (LS), gutted LT, gutted LS and gutted M are provided. 相似文献

Summary The reproduction of bacteriophages T1–T7 inE. coli B growing in a continuous culture apparatus at constant generation times of 50′ and 150′ was studied in a defined medium
with a high concentration of glucose and in a medium with glucose as a limiting factor.
It was shown that the propagation rate (as measured by the latent period) of phages T2, T4, T6 and T7 decreased with longer bacterial generation times and with reduced energy- and carbon-supply. In contrast the reproduction
of phages T1, T3 and T5 (which are mainly synthesized from the contents of the host cell) was unaffected by the slowing down of bacterial metabolism. 相似文献

The freezing of water in acclimated and nonacclimated cereals was studied using pulsed nuclear magnetic resonance spectroscopy. The quantity of unfreezable water per unit dry matter was not strongly dependent on the degree of cold acclimation. In contrast, the fraction of water frozen which was tolerated by nonacclimated winter cereals and by an acclimated spring wheat (Triticum aestivum L.) was less than in acclimated hardy cereals. The freezing curves had the following form:LT = L0ΔTm/T + KLT and L0 are liquid water per unit dry matter at T and 0 C, respectively. ΔTm is the melting point depression and K is the liquid water which does not freeze. 相似文献

Satiation-dependent, intra-cohort variations in prey size selection of young roach (Rutilus rutilus)
The tolerance to freezing and thawing of Leucodon sciuroides, a moss growing in mountainous areas of the Mediterranean (south-east Spain), was investigated by means of CO2 gas exchange, modulated chlorophyll (Chl) a fluorescence and pigment analysis by high-performance liquid chromatography. Evidence is presented for freezing-induced decreases
in CO2 fixation that enhance non-radiative dissipation of absorbed light energy, a process which protects the photosynthetic apparatus.
The photosynthetic apparatus of L. sciuroides remained fully recuperable after freezing, as indicated by the recovery of photosynthetic CO2 fixation and Chl fluorescence parameters to pre-freezing values during thawing. The rapid recovery of photosynthesis activity
during thawing in L. sciuroides suggests that this moss is capable of tolerating freeze-thaw cycles in a manner similar to that found at higher latitudes
or in the Antarctic. The resistance of the photosynthetic apparatus of this moss to freezing might be achieved, at least partially,
through the employment of dissipative pathways, such as non-radiative dissipation of absorbed light energy.

The temporal aspect of thyroxine (T4) enhanced development of several fetal adipose tissue depots (locations) and skin was examined in the present study. On day 70 of gestation pig fetuses were either hypophysectomized (hypox), hypoxed and implanted with T4 pellets or left intact (control). Subsequently, fetuses were removed for study at either 73, 75, 80, 85 and 90 days of gestation. Serum levels of T4 and insulin-like growth factor I (IGF-I) were significantly elevated by T4 after 3 days of treatment and throughout the study. T4 treatment enhanced development of skin, inner and outer subcutaneous (SQ) adipose tissue and adipocyte lobules around hair follicles (HFL's) but degree of response and response time were tissue or depot dependent. The T4 response time was shortest for skin and HFL's, longest for inner SQ and intermediate for the outer SQ. Considering the entire treatment period, magnitude of the T4 response was much greater for skin and HFL's than for outer and inner SQ tissues. Possibly, these developmental characteristics indicate that T4 directly influences skin and HFL's and indirectly influences inner SQ adipose tissue by increasing production of a locally produced adipogenic growth factor. Furthermore, developmental characteristics (morphological) indicated that putative local growth factor mediation of T4 action may depend on stage of development or maturity of the tissue. IGF-I is clearly the most logical candidate as a putative local mediator of T4, but evidence at the molecular level is needed to prove this suggestion. Regardless, the particular adipose tissue location or depot is an important aspect of hormone responsiveness during the critical or sensitive period of fetal adipose tissue development. 相似文献

We determined the homogeneous nucleation temperature depression, ΔTf,hom, the equilibrium melting point depression, ΔTm, and the value λ, which can be obtained from the linear relationship ΔTf,hom = λΔTm, for aqueous solutions of PEG (200-20,000 g mol−1), PVP (10,000, 35,000, 40,000 g mol−1), and dextran (10,000 g mol−1) in the concentration range 0-40 wt% using the emulsion method. The molecular weight dependence of Tf,hom, Tm, and λ in PEG aqueous solutions was found to change in the vicinity of Mw 600-1540 at all concentrations. In addition, it was confirmed that for all of the polymers studied, there was a good linear relationship between λ and the logarithmic value of the self-diffusion coefficient D0 of the solute molecule. These results indicate that the parameters that describe non-equilibrium freezing, such as Tf,hom and λ, are dependent on solution properties such as viscosity and self-diffusion of solute molecules. 相似文献

The purpose of these studies was to determine the effect of thyroidectomy (Tx), and thyroid hormone (T3/T4) treatment on concentrations of plasma CT in chicks. In addition, the turnover of CT in Tx- and T3/T4-treated chicks was estimated using a novel nonradioactive salmon CT preparation. One-week-old broiler chicks (Gallus domesticus) (n=75) were divided into three groups. Group I was sham-injected daily (i.m. saline), Group II was injected with 50 μg/day of T3/T4 while Group III was injected with the goitrogen, methimazole, (150 mg/kg BW per day) for 8 weeks. Chicks (8–9 weeks old) were implanted with catheters in the brachial wing vein and administered ruthenium-labeled salmon CT. Blood samples were collected at 30 s, 1, 2, 4, 8, 20 min, and 3 h after injection. Results showed that concentrations of plasma CT were decreased in T3/T4-injected birds. There was no significant effect of methimazole on circulating concentrations of plasma CT. The half-life of CT was significantly increased (P<0.05) in both T3/T4-injected (n=6; 1.34±0.16 min) and goitrogen-treated birds (n=2; 5.81±2.83 min) compared to controls (n=7; 54±3 s) The results demonstrate that changes in concentrations of plasma thyroid hormones can significantly affect concentrations of plasma CT. 相似文献

Novel actinobacterial strains, PAGU 1247T, PAGU 1251 and PAGU 1252, were isolated from the skin of atopic dermatitis patients and were characterized using a polyphasic approach. Phylogenetic analyses based on 16S rRNA gene sequences showed that these isolates were located within the family Dermacoccaceae. The most closely related species of PAGU 1247T in phylogenetic terms was Branchiibius hedensis Mer 29717T, with 16S rRNA gene sequence similarity of 99.6%, although the DNA–DNA relatedness value was less than 43.9%. Some biochemical traits, such as lipase (C14) and α-galactosidase activity, could distinguish these isolates from B. hedensis. Strain PAGU 1247T contained iso-C16:0 and brC18:0 as the major fatty acids. The quinone system consisted of menaquinone MK-8(H6 and H4). The G + C content of the genomic DNA was 67.6 mol%. On the basis of its phenotypic properties and genetic distinctiveness, strains PAGU 1247T, PAGU 1251 and PAGU 1252 represents a novel species of the genus Branchiibius, for which the name Branchiibius cervicis sp. nov. is proposed. The type strain is PAGU 1247T (=NBRC 106593T = DSM 24166T). 相似文献
