Kefir is a probiotic that has several health promising properties. Its grains can form microbial films on different types of substrates. In the present work, the surface characteristics of kefir biofilms associated with Maytenus rigida Mart. extract were minutely studied. Three different concentrations of plant extract were included in the biofilm forming solutions, where fresh grains of kefir were inoculated. The results showed that the plant extract was successfully incorporated into the exopolysaccharide matrix of the biofilm. The main chemical components found linked to the plant extract were triterpenes. The crystallinity of biofilms increased with the addition of the plant extract. The morphology revealed that at low concentrations of the extract there was a prevalence of lactobacilli, while at high concentrations yeasts were more observed. Adhesion and wettability were higher for biofilm with less extract. These results revealed that a combination of plant extract and kefir's exopolysaccharide could form biofilms with chemical and topographic properties of great interest in regenerative medicine.

Migraine is a multifactorial neurovascular disorder, which affects about 12% of the general population. In episodic migraine, the visual cortex revealed abnormal processing, most likely due to decreased preactivation level. Transcranial direct current stimulation (tDCS) is able to modify cortical excitability and might result in an alleviation of migraine occurrence if used repetitively.

To test the hypothesis that self-administered anodal tDCS over the visual cortex significantly decreases the number of monthly migraine days in episodic migraine.

The study was single-blind, randomized, and sham-controlled. Inclusion criteria were age 18-80 years and an ICHD-3 diagnosis of episodic migraine. Exclusion criteria were pregnancy, presence of a neurodegenerative disorder, a contraindication against MRI examinations, and less than two migraine days during the 28-day baseline period. Patients in whom the baseline period suggested chronic migraine were excluded. After baseline, participants applied daily eitherificantly lower number of monthly migraine days. see more However, it has neither an immediate nor a long-term effect.

This study provides Class II evidence that self-administered anodal tDCS over the visual cortex in episodic migraine results in a significantly lower number of monthly migraine days. However, it has neither an immediate nor a long-term effect.

This study aimed to identify the postoperative histological features affecting the prognosis of patients with early-stage cervical cancer who underwent open radical hysterectomy.

This retrospective study enrolled 374 patients with pT1a, 1b1 and 2a1 early-stage cervical cancer who underwent open radical hysterectomy between 2001 and 2018. Survival outcomes were analyzed by Kaplan-Meier method and compared with log-rank test. Using the Cox proportional hazards regression test, we conducted a multivariate analysis for disease-free survival and overall survival.

Others histology, including other epithelial tumors and neuroendocrine tumors, had a significantly worse prognosis in both disease-free survival and overall survival than those of squamous cell carcinoma and adenocarcinoma (hazard ratio, 4.37 and 11.76; P = 0.006 and P = 0.002, respectively), along with lymph node metastasis (hazard ratio, 2.99 and 7.03; P = 0.009 and P = 0.001, respectively).

Others histology including adenosquamous carcinoma had a poor prognosis in early-stage cervical cancer as with high-risk factors.

Yet, the mechanisms linking CSA to adverse outcomes have rarely been investigated within a longitudinal design. The current study aimed to examine the role of affect dysregulation in the association between depressive symptoms and suicidal ideation 1year after the first assessment in a sample of 119 sexually abused adolescent girls. An integrative mediational model was conceptualized to examine the explicatory role of affect dysregulation (Time 2) in the association between depressive symptoms (Time 1) and suicidal ideation (Time 3). Approximately 31% of the girls reported suicidal ideation at Time 3. Path analysis with logistic regressions revealed that the association between depressive symptoms and suicidal ideation presence was partly explained by affect dysregulation, which increased the risk of suicidal ideation presence by 18.4%, OR = 1.18, 95% CI [1.07, 1.33]. The integrative model explained 21.5% of the variance in suicidal ideation. These findings identify potential predictors of suicidal ideation among sexually abused adolescent girls. This present study highlights the role of affect dysregulation in the presence of suicidal ideation and provides potential targets for intervention practices when working with adolescent girl victims of CSA. As such, interventions for this vulnerable population should aim to decrease depressive symptoms and affect dysregulation to reduce suicidal risk.Endolithic (rock-dwelling) microbial communities are ubiquitous in hyper-arid deserts around the world and the last resort for life under extreme aridity. These communities are excellent models to explore biotic and abiotic drivers of diversity because they are of low complexity. Using high-throughput amplicon and metagenome sequencing, combined with X-ray computed tomography, we investigated how water availability and substrate architecture modulated the taxonomic and functional composition of gypsum endolithic communities in the Atacama Desert, Chile. We found that communities inhabiting gypsum rocks with a more fragmented substrate architecture had higher taxonomic and functional diversity, despite having less water available. This effect was tightly linked with community connectedness and likely the result of niche differentiation. Gypsum communities were functionally similar, yet adapted to their unique micro-habitats by modulating their carbon and energy acquisition strategies and their growth modalities.
