Stomata respond to darkness by closing to prevent excessive water loss during the night. Although the reorganisation of actin filaments during stomatal closure is documented, the underlying mechanisms responsible for dark-induced cytoskeletal arrangement remain largely unknown. We used genetic, physiological and cell biological approaches to show that reorganisation of the actin cytoskeleton is required for dark-induced stomatal closure. The opal5 mutant does not close in response to darkness but exhibits wild-type (WT) behaviour when exposed to abscisic acid (ABA) or CaCl2 ...

Saniyya Khan, Imrana Naseem
The accompanied tissue devastation and systemic toxicity of chemotherapy has shifted the quest for having an effective and palliative cancer therapy towards photodynamic therapy (PDT). Riboflavin (Rf), an essential micronutrient is emerging as a potent tool of PDT, due to its excellent photosensitizing properties. It can be used as an efficient adjuvant for various anticancer drugs. The hemolytic and proteolytic effect of photoilluminated aminophylline (Am), a xanthine derivative, and Rf is well documented in literature...

Bilateral diffuse uveal melanocytic proliferation (BDUMP) is a rare paraneoplastic intraocular disease that causes progressive visual loss in patients driven by an IgG factor associated with an underlying malignancy. Characteristic ocular findings include exudative retinal detachment, rapid cataract formation and uveal melanocytic tumours. The awareness and documentation of BDUMP has increased during the past decade, and the increasing amount of data collected demonstrates the effect of treatment with plasmapheresis and the value of diagnostic tools in BDUMP such as genetic and immunologic investigations...

Aptamers are nucleic acids referred to as chemical antibodies as they bind to their specific targets with high affinity and selectivity. They are selected via an iterative process known as 'selective evolution of ligands by exponential enrichment' (SELEX). Aptamers have been developed against numerous cancer targets and among them, many tumor cell-membrane protein biomarkers. The identification of aptamers targeting cell-surface proteins has mainly been performed by two different strategies: protein- and cell-based SELEX, when the targets used for selection were proteins and cells, respectively...

Thyroid cancers are common endocrine malignancies that comprise tumors with different clinical and histological features. Indeed, papillary and follicular thyroid cancers are slow-growing, well-differentiated tumors, whereas anaplastic thyroid cancers are undifferentiated neoplasias that behave much more aggressively. Well-differentiated thyroid carcinomas are efficiently cured by surgery and radioiodine, unlike undifferentiated tumors that fail to uptake radioactive iodine and are usually resistant to chemotherapy...

OBJECTIVE: To demonstrate the clinical efficacy of topical 5% imiquimod for mycosis fungoides (MF) tumors. BACKGROUND: Treatment of tumor-stage MF represents a therapeutic challenge because of a limited number of effective topical therapies. Single tumors can be treated with localized radiation but may recur. Systemic therapies are also an option but are associated with serious adverse effects. Imiquimod is a topical agent whose efficacy has been documented in treating MF patches and plaques as well as one case of tumor-stage disease...

The association of infantile spasms and periventricular leukomalacia and/or intraventricular hemorrhage is well documented. Data regarding early treatment-based and long-term outcomes are limited. A retrospective chart review identified children with infantile spasms born prematurely (<37 weeks) with diagnoses of periventricular leukomalacia and/or intraventricular hemorrhage. Thirteen children were included. Median gestational age was 30 weeks and age of onset of infantile spasms was 8 months. Nine children had intraventricular hemorrhage, 10 had periventricular leukomalacia, and 6 children had both...

Compartmentalization is both a fundamental principle of cellular organization and an emerging theme in prokaryotic biology. Work in the past few decades has shown that protein-based organelles called microcompartments enhance the function of encapsulated cargo proteins. More recently, the repertoire of known prokaryotic organelles has expanded beyond microcompartments to include a new class of smaller proteinaceous compartments, termed nanocompartments (also known as encapsulins). Nanocompartments are icosahedral capsids that are smaller and less complex than microcompartments...

We assessed potential factors associated with "current" or "ever" self-injurious behaviors, reported in the Autism Diagnostic Interview-Revised, among children with autism spectrum disorder (n = 692) from the Study to Explore Early Development. Data on factors examined were obtained from questionnaires, standardized clinical instruments, and birth certificates. We employed a log-binomial regression to assess these associations. Although most associations were quite similar for currently and ever exhibiting self-injurious behaviors, a few differences were noted...

PURPOSE: Histological confirmation of endometrial cancer by dilatation/curettage (D/C) in women with postmenopausal bleeding (PMB) can be challenging due to anesthesiological and/or surgical risks. Thus, less invasive methods for diagnostics are required to identify patients with minimal risk for endometrial cancer (EC) to avoid unnecessary surgical intervention. The objective of this single-center cohort study was to assess the diagnostic validity of transvaginal ultrasound (TVUS) measurements of endometrial thickness (ET) in patients with PMB for the detection of EC...

Psoriatic Arthritis (PsA) is characterized by bone erosive damage often associated with exuberant bone formation especially in enthesial sites. Dkk-1 and sclerostin are the main inhibitors of the WNT/β-catenin signaling pathway and play a key role in the regulation of both bone formation and resorption. We performed this study in order to compare the serum levels of the WNT-pathway regulators along with bone turnover markers (BTM) and parathyroid hormone (PTH) between three different groups: one group of female patients affected by PsA, one group of female patients affected by rheumatoid arthritis (RA), and healthy female controls (HC)...

Age assessment in children and young adults is a relevant forensic issue. It is requested not only in evaluating criminal responsibility in youths without proper identification documents, often in relation to age thresholds, but also for release of a residency permit, and asylum seekers of minors. The analysis of the Risser sign and the iliac crest ossification process has been proposed as a useful tool for forensic age estimation. We evaluated the applicability of three different age estimation methods on a sample of 497 pelvic radiographs of Italian individuals between 10 and 25 years of age...

Currently we observe a gap between theory and practices of patient engagement. If both scholars and health practitioners do agree on the urgency to realize patient engagement, no shared guidelines exist so far to orient clinical practice. Despite a supportive policy context, progress to achieve greater patient engagement is patchy and slow and often concentrated at the level of policy regulation without dialoguing with practitioners from the clinical field as well as patients and families. Though individual clinicians, care teams and health organizations may be interested and deeply committed to engage patients and family members in the medical course, they may lack clarity about how to achieve this goal...

Life is mechanobiological: mechanical stimuli play a pivotal role in the formation of structurally and functionally appropriate body templates through mechanobiologically-driven cellular and tissue re/modeling. The body responds to mechanical stimuli engendered through physical movement in an integrated fashion, internalizing and transferring forces from organ, through tissue and cellular length scales. In the context of rehabilitation and therapeutic outcomes, such mechanical stimuli are referred to as mechanotherapy...
