Transcranial magnetic stimulation (TMS) is a noninvasive technique to assess neural impulse conduction along the cortico-diaphragmatic pathway. The reliability of diaphragm motor-evoked potentials (MEP) induced by TMS is unknown. Notwithstanding large variability in MEP amplitude, we found good-to-excellent reproducibility of all MEP characteristics (latency, duration, amplitude, and area) both within- and between-day in healthy adult men and women. Our findings support the use of TMS and surface EMG to assess diaphragm activation in humans.

Abstract Objective To describe our hospital's experience following expectant management of previable preterm prelabor rupture of membranes (pPPROM). Study Design Retrospective review of neonatal survival and maternal and neonatal outcomes of pPPROM cases between 2012 and 2019 at a tertiary referral center in South Central Louisiana. Regression analyses were performed to identify predictors of neonatal survival. Results Of 81 cases of pPPROM prior to 23 weeks gestational age (WGA), 23 survived to neonatal intensive care unit discharge (28.3%) with gestational age at rupture ranging from 180/7 to 226/7 WGA. Increased latency (adjusted odds ratio [aOR] = 1.30, 95% confidence interval [CI] = 1.11, 1.52) and increased gestational age at rupture (aOR = 1.62, 95% CI = 1.19, 2.21) increased the probability of neonatal survival. Antibiotics prior to delivery were associated with increased latency duration (adjusted hazard ratio = 0.55, 95% CI = 0.42, 0.74). Conclusion Neonatal survival rate following pPPROM was 28.3%. Later gestational age at membrane rupture and increased latency periods are associated with increased neonatal survivability. Antibiotic administration following pPPROM increased latency duration.

Attempts have been made to correlate different instability indices among themselves statistically. The study reveals that the Showalter Stability Index (SI) has moderate to good correlations with different instability indices except Dew-point Index (DPI), Vertical Total Index (VT), Modified Vertical Total Index (MVT) and Modified K-Index (MK). Most of the correlations co-efficient are found to be significant up to 99% level of significance except Dry Instability Index (DII), which has correlation with SI up to 95% level of significance. Lifted Index (LI) has moderate to good correlation with different instability indices except DII, K-Index (KI) and MVT. Most of the correlations co-efficient are significant up to 99% level of significance except VT, SWEAT Index (SWI) and MKI, which have correlation with LI up to 95% level of significance. Unmodified instability indices have moderate to strong correlation with the corresponding modified instability indices, having 99% level of significance. The correlation co-efficient of VT and MVT, SWI and Modified SWEAT Index (MSWI), and KI and MKI are comparatively large. Standard errors of estimate are small in almost all the cases except a few. The regression equations obtained are likely to be helpful in the computation of different instability indices.

Assessment of genetic diversity for various traits would contribute in hybridization projects in order to recover aspired recombinants. Therefore, metroglyph analysis and ANOVA were conducted out to estimate genetic diversity among seven caraway genotypes. Field experiment was applied in winter season of 2011/2012 with three replicates. Consequently, data were recorded on plant height, branches no., umbels no. umbels diameter, no. of umbellets and plant yield. Results showed that allotting of index scores for each trait of seven caraway genotypes represented the worth of the genotype in respects to the trait which the performance of genotype is represented by total index score for all traits of that genotype. Thus, Bery and Mosul genotypes ascertained the highest index scores of 16, for each one. Moreover, Metroglyph scatter diagram revealed three groups of caraway genotypes. Therefore, it could be concluded that metroglyph technique simply classified genotypes to groups and had potentiality to interpret genotypes performance regarding the index scores. Thus, it could be recommended to apply crossing or hybridization between individuals from different groups alternatively to individuals from same group. Genotypes of Bery, Mosul, Sury and selectedF1 (Group2), and Balady (Group3) were distinct which possible to apply crossing between one of group2 individuals with another one of group3.

Highly cooperative social species are expected to engage in frequent reconciliation following conflicts in order to maintain pack cohesiveness and preserve future cooperation. By contrast, in social species with low reliance on cooperation, reconciliation is expected to be less frequent. Here, we investigate the pattern of reconciliation in four captive wolf packs and four captive dog packs. We provide evidence for reconciliation in captive wolves, which are highly dependent on cooperation between pack members, while domestic dogs, which rely on conspecific cooperation less than wolves, avoided interacting with their partners after conflicts. Occurrence, intensity, latency, duration and initiation of wolf reconciliations appeared to vary as a consequence of a compromise between the costs (e.g. risk of further aggression) and the benefits (e.g. restoring relationship with opponents) of such interactions. Our results are in line with previous findings on various wolf packs living under different social and ecological conditions, suggesting that reconciliation is an important strategy for maintaining functional relationships and pack cohesiveness. However, current results on dogs are in contrast to the only other study showing that reconciliation can occur also in this species. Therefore, the occurrence of reconciliation in dogs may be influenced by social and environmental conditions more than in wolves. Which factors promote and modulate reconciliation in dogs needs to be further investigated.

The present study evaluates the anticonvulsant activity of the roots of Anacyclus pyrethrum using pilocarpine-induced experimental model of epilepsy in rat, and to determine its possible anticonvulsant mechanism. Ethanol extract (200 and 400 mg/kg) or alkylamides (25 and 50 mg/kg) was administered orally 45 min before the injection of pilocarpine-induced (400 mg/kg) seizures. The possible anticonvulsant mechanism was investigated by testing the effect of atropine (2 mL/kg) and scopolamine (1 mg/kg). The scoring of seizure severity, seizures time latency, duration of total seizures and percentage of mortality protection were recorded. Ethanol extract and alkylamides prolonged the time of onset seizure and decreased the duration of seizures compared to control group (p<0.001). The seizure protection was 100%. The co-administered of ethanol extract of A. pyrethrum and alkylamides with atropine completely abolished the pilocarpine-induced seizures.

Purpose. To investigate disk halo size changes produced by a glare source after surgical insertion of an implantable collamer lens with a central hole (ICL V4c) for myopia correction. Methods. In this prospective study, disk halo size and pupillary light response with a vision monitor were measured preoperatively and at 1 week, 1 month, and 3 months postoperatively. Pupillary light response parameters included contraction amplitude, latency, duration, and velocity; dilation latency, duration, and velocity; and initial, maximum, minimum, and average pupil diameters. Results. Forty-two right eyes of 42 patients were enrolled. Postoperative uncorrected distance visual acuity was better than or equal to 20/20 in all eyes. Compared to preoperative values, disk halo size showed no significant difference at 1 week postoperatively (P>0.05) and then decreased significantly at 1 and 3 months postoperatively (both P<0.001). Contraction amplitude and velocity, as well as dilation velocity, decreased significantly at all postoperative time points (all P<0.001). Disk halo size at 3 months postoperatively was significantly correlated with initial (r = 0.446, P=0.003), maximum (r = 0.483, P=0.001), minimum (r = 0.425, P=0.005), and average pupil diameters (r = 0.474, P=0.002). Conclusions. After ICL V4c implantation, disk halo size was reduced in the short term. Patients with smaller pupil sizes during pupillary response to light experienced smaller halos after ICL V4c implantation.

A group of 40 patients suffering from migraine underwent dihydroergotamine-retard therapy for a period of five months after a 30-day pre-treatment period. They had previously been treated with other medications but results were not relevant. Drug effectiveness was evaluated by means of Pain Total Index, number of attacks, analgesic consumption and number of awakenings with headache. The results show a significant difference between the observation period and the treatment phase, with relevant therapeutic success. Only moderate side-effects were observed. La dihydroergotamine à libération programmée a été administrée pendant cinq mois à quarante patients souffrants de céphalée qui avaient déjà été traités avec d'autres médicaments sans obtenir un résultat appréciable. Le commencement de la thérapie était précédé par une période d'observation de trente jours. L'éfficacité du traitement a été évaluée au moyen du Pain Total Index, de la fréquence des crises, de la consommation des analgésiques et du nombre de réveils avec la céphalée. Les résultats indiquent des différences significatives du point de vue de la statistique par rapport à la période d'observation. La thérapie a permis des succès thérapeutiques remarquables, vue aussi la mancance d'effets collatéraux qui auraient conseiller la suspension du traitement ou bien la réduction de la posologie. A quaranta pazienti affetti da cefalea emicranica e già trattati con scarsi risultati con altri farmaci, è stata somministrata diidroergotamina a cessione programmata per cinque mesi. Un periodo di osservazione di trenta giorni precedeva l'inizio della terapia. L'efficacia del trattamento è stata valutata per mezzo del Pain Total Index, della frequenza delle crisi, del consumo degli analgesici e del numero di risvegli con cefalea. I risultati mostrano differenze statisticamente significative rispetto al periodo di osservazione. La terapia ha permesso rilevanti successi terapeutici, in assenza di effetti collaterali tali da indurre la sospensione del trattamento o la riduzione della posologia.
