Plant morphogenesis relies exclusively on oriented cell expansion and division. Nonetheless, the mechanism(s) determining division plane orientation remain elusive. Here, we studied tissue healing after laser-assisted wounding in roots of Arabidopsis thaliana and uncovered how mechanical forces stabilize and reorient the microtubule cytoskeleton for the orientation of cell division. We identified that root tissue functions as an interconnected cell matrix, with a radial gradient of tissue extendibility causing predictable tissue deformation after wounding...

INTRODUCTION: Serum levels of procalcitonin and C-reactive protein (CRP) have been used to predict anastomotic leakage after colorectal surgery, but information is scarce in advanced ovarian cancer (AOC) surgery with bowel resection. This study aimed to assess the predictive value of procalcitonin and CRP in detecting anastomotic leakage after AOC surgery with bowel resection. The study also aimed to determine the optimal postoperative reference values and the best day for evaluating these markers...

Surfactin is a natural surfactant almost exclusively produced by Bacillus species with excellent physical-chemical, and biological properties. Among innovative applications, surfactin has been recently used as an ingredient in formulations. The antibacterial and anti-acne activities, as well as the anti-wrinkle, moisturizing, and cleansing features, are some of the reasons this lipopeptide is used in cosmetics. Considering the importance of biosurfactants in the world economy and sustainability, their potential properties for cosmetic and dermatological products, and the importance of patents for technological advancement in a circular bioeconomy system, the present study aims to review all patents involving surfactin as an ingredient in cosmetic formulas...

This study evaluates our experience with Tezepelumab for those patients who received the indicated drug off-label prior to its commercialization. METHODS: We conducted a real-life observational study on three patients from the Severe Asthma Unit of the Hospital Universitario de Fuenlabrada, Spain, who received Tezepelumab off-label before its official approval...

BACKGROUND: Obsessive-compulsive disorder (OCD) and co-occurring posttraumatic stress disorder (PTSD) is associated with more severe and chronic OCD. However, findings regarding treatment effectiveness of cognitive behavioral treatment (CBT) with exposure and response prevention (ERP) with this comorbidity are mixed. Research aimed at understanding the precise barriers to OCD treatment effectiveness for individuals with co-occurring PTSD may help elucidate unique treatment needs. METHODS: The current study used linear regression and latent growth curve analysis comparing treatment response and trajectory from patients with OCD (n = 3083, 94...

OBJECTIVE: Vitamin D (VD) is a fat-soluble steroid hormone, synthesized by the skin, most known for its role in bone mineral balance. Vitamin D receptors (VDR) are also found in the female reproductive system, but their role remains unclear. The objective of this study was to analyze the relationship between serum vitamin D levels and the number of oocytes retrieved after ovarian stimulation. METHODS: This is a retrospective study involving 267 patients undergoing in vitro fertilization (IVF) carried out in the Fertipraxis clinic, a private practice facility...

Contraction and flow of the actin cell cortex have emerged as a common principle by which cells reorganize their cytoplasm and take shape. However, how these cortical flows interact with adjacent cytoplasmic components, changing their form and localization, and how this affects cytoplasmic organization and cell shape remains unclear. Here we show that in ascidian oocytes, the cooperative activities of cortical actomyosin flows and deformation of the adjacent mitochondria-rich myoplasm drive oocyte cytoplasmic reorganization and shape changes following fertilization...

BACKGROUND: In the different published studies, there is no consensus on the efficacy of virtual reality as an adjuvant treatment of mood states. AIM: The aim of this study is to evaluate the impact of no immersive virtual reality with the Nintendo Switch device in rehabilitation treatment on mood, anxiety and depression in stroke patients admitted to neurorehabilitation units. METHODS: Fifty-eight patients admitted to neurorehabilitation units underwent a 1:3 multicentre randomised clinical trial...

BACKGROUND: Post-stroke depression is the most common neuropsychiatric consequence and reduces rehabilitation effectiveness. However, the efficacy of virtual reality (VR) on mental health treatment for patients after a stroke is uncertain. AIMS: The aim of this study was to evaluate the efficacy of VR as a co-adjuvant form of treatment to reduce depression in stroke patients admitted to neurorehabilitation units. METHODS: We systematically searched medical databases including PubMed, CINAHL, PsycINFO, Embase, Cochrane Library, Web of Science, and ClinicalTrials...

The utilization of host-cell machinery during SARS-CoV-2 infection can overwhelm the protein-folding capacity of the endoplasmic reticulum and activate the unfolded protein response (UPR). The IRE1α-XBP1 arm of the UPR could also be activated by viral RNA via Toll-like receptors. Based on these premises, a study to gain insight into the pathogenesis of COVID-19 disease was conducted using nasopharyngeal exudates and bronchioloalveolar aspirates. The presence of the mRNA of spliced XBP1 and a high expression of cytokine mRNAs were observed during active infection...

AIM: To evaluate the relevance of signs and symptoms for the clinical identification of ESI and TI in HD-CVC, by means of international expert consensus, and to reach a consensus on a definition and clinical management (CM) for these infections. BACKGROUND: A recent systematic review showed a high heterogeneity in the signs/symptoms used for determining exit site infection (ESI) and tunnel infection (TI) of haemodialysis central venous catheter (HD-CVC). DESIGN: A modified Delphi ranking process was carried out between November 2020 and March 2021, consisting of four rounds using an online questionnaire with a panel of 26 experts from 12 countries...

Objectives Stereotactic radiosurgery combined with pharmacological treatment is currently one of the most acceptable alternatives for the treatment of trigeminal neuralgia (TN). Our primary endpoint was to report the short-term response (one month) outcomes of 10 patients with refractory TN after CyberKnife® (CK) radiosurgery; secondary endpoints were to assess early side effects and complications. Methods Ten female patients with TN refractory to pharmacological and/or non-pharmacological treatment received a single dose of 90 Gy with CyberKnife® radiosurgery...

Antibodies directed against donor-specific human leukocyte antigens (HLAs) can be detected de novo after heart transplantation and play a key role in long-term survival. De novo donor-specific antibodies (dnDSAs) have been associated with cardiac allograft vasculopathy, antibody-mediated rejection, and mortality. Advances in detection methods and international guideline recommendations have encouraged the adoption of screening protocols among heart transplant units. However, there is still a lack of consensus about the correct course of action after dnDSA detection...

Autophagy induction involves extensive molecular and membrane reorganization. Despite substantial progress, the mechanism underlying autophagy initiation remains poorly understood. Here, we used quantitative photoactivated localization microscopy with single-molecule sensitivity to analyze the nanoscopic distribution of endogenous ULK1, the kinase that triggers autophagy. Under amino acid starvation, ULK1 formed large clusters containing up to 161 molecules at the endoplasmic reticulum. Cross-correlation analysis revealed that ULK1 clusters engaging in autophagosome formation require 30 or more molecules...
