SMARCB1-Deficient Sinonasal Carcinoma: Case Report and Review of the Literature.

BACKGROUND SMARCB1-deficient sinonasal carcinoma is a rare neoplasm with inactivation of the SWI/SNF complex, with an aggressive clinical course as most of the lesions present as advanced in pT3/T4 stages with frequent recurrence, and many patients succumb to the disease. Reported initially in 2014, the lesion has male predominance, with an age range of 19 to 89 years and predilection for the ethmoid sinus and nasal cavity. Histopathological findings show a proliferation of small- to medium-sized monomorphic basaloid cells with indistinctive cytoplasmic borders and round variably prominent nuclei with scattered cells that show rhabdoid morphology. Cytoplasmic vacuoles are common. It has similar morphological findings to a wide array of neoplasms in the sinonasal area. CASE REPORT We report a case of SMARCB1-deficient sinonasal carcinoma in a 30-year-old man referred to our hospital with a preliminary diagnosis of sinonasal adenocarcinoma, intestinal type. Computed tomography showed a huge destructive soft tissue mass in the left maxillary sinus, extended to involve the left nasal cavity with extension to the skull base and perineural spread along the foramen rotundum. Histological examination revealed a malignant basaloid neoplasm embedded in a myxoid stroma that showed loss of SMARCB1 stain. The patient was treated with induction chemotherapy using etoposide and cisplatin for disease control. CONCLUSIONS SMARCB1-deficient sinonasal carcinoma is a rare neoplasm with an aggressive clinical course and high-grade behavior despite having uniform cytological features. This poses complex diagnoses, especially in small biopsies. Incorporating morphological findings with ancillary tests is required to identify this high-grade malignancy.

Installing the neurospora carotenoid pathway in plants enables cytosolic formation of provitamin A and its sequestration in lipid droplets.

Vitamin A deficiency remains a severe global health issue, which creates a need to biofortify crops with provitamin A carotenoids (PACs). Expanding plant cell capacity for synthesis and storing of PACs outside the plastids is a promising biofortification strategy that has been little explored. Here, we engineered PAC formation and sequestration in the cytosol of Nicotiana benthamiana leaves, Arabidopsis seeds, and citrus callus cells, using a fungal (Neurospora crassa) carotenoid pathway that consists of only three enzymes converting C

No Signs of Inclusive Fitness or Reciprocal Altruism in Advantageous Inequity Aversion.

Advantageous inequity aversion (i.e., the tendency to respond negatively to unfairness that benefits oneself) usually develops in 6-8-year-olds. However, little is known about the selection pressures that might have shaped this phenomenon. Using data collected from 120 4-8-year-old Finnish children, we tested two evolutionary explanations for the development of advantageous inequity aversion: reciprocal altruism (i.e., benefiting from sharing when the roles are likely reversed in the future) and inclusive fitness (i.e., benefiting from sharing with biological relatives that carry the same alleles). We first successfully replicated a previous experiment, showing that 6-8-year-olds display advantageous inequity aversion by preferring to throw away a resource rather than keep it for themselves. Here, this behavior was also displayed in 5-year-olds. Using a novel experiment, we then asked children to distribute five erasers between themselves, a sibling, a peer, and a stranger. That is, an equal distribution was only possible if throwing away one eraser. We found no support for advantageous inequity aversion being shaped by either inclusive fitness or reciprocal altruism. Future studies could investigate costly signaling and adherence to social norms to avoid negative consequences as ultimate explanations for advantageous inequity aversion.

Chironomidae in shallow water bodies of a protected lowland freshwater floodplain ecosystem.

Lowland floodplains are complex ecosystems comprised of standing and flowing waters interacting with terrestrial habitats, and the main force creating, shaping and influencing, both habitats and biotic communities, is a hydrological regime and water supply from the parent river. In areas not much altered by anthropogenic influence, the Danube creates such floodplain areas, and temporary shallow water bodies within represent biodiversity important habitats. In the Kopački Rit Nature Park floodplain in Croatia, diversity based on Chironomidae (Diptera) in both benthic and epiphytic communities was studied in eight ponds (temporary shallow water body) and at two channel locations (permanent shallow water body). At each location samples of sediment and macrophytes were taken at three sites. The benthic chironomid community was comprised of 29 taxa, most abundant being representatives of the

Recent advancement in protected delivery methods for carotenoid: a smart choice in modern nutraceutical formulation concept.

Carotenoids are fat-soluble bio pigments often responsible for red, orange, pink and yellow coloration of fruits and vegetables. They are commonly referred as nutraceutical which is an alternative to pharmaceutical drugs claiming to have numerous physiological benefits. However their activity often get disoriented by photonic exposure, temperature and aeration rate thus leading to low bioavailability and bio accessibility. Most of the market value for carotenoids revolves around food and cosmetic industries as supplement where they have been continuously exposed to rigorous physico-chemical treatment. Though several encapsulation techniques are now in practice to improve stability of carotenoids, the factors like shelf life during storage and controlled release from the delivery vehicle always appeared to be a bottleneck in this field. In this situation, different technologies in nanoscale is showing promising result for carotenoid encapsulation and delivery as they provide greater mass per surface area and protects most of their bioactivities. However, safety concerns related to carrier material and process must be evaluated crucially. Thus, the aim of this review was to collect and correlate technical information concerning the parameters playing pivotal role in characterization and stabilization of designed vehicles for carotenoids delivery. This comprehensive study predominantly focused on experiments carried out in past decade explaining how researchers have fabricated bioprocess engineering in amalgamation with nano techniques to improve the bioavailability for carotenoids. Furthermore, it will help the readers to understand the cognisance of carotenoids in nutraceutical market for their trendy application in food, feed and cosmeceutical industries in contemporary era.

The Impact of Homelessness, Substance Use, and Mental Illness on Surgical Inpatient Outcomes in Australia.

This study investigated inpatient surgical outcomes for people experiencing homelessness (PEH) in Australia. Retrospective administrative health data of emergency surgical admissions from a single center over five years, 2015 to 2020, was included. Independent associations between factors and outcomes were analyzed with binary logistic and log-linear regression. Of 11 229 admissions, 2% were experiencing homelessness. People experiencing homelessness were on average younger (49 vs 56 years), more likely to be males than females (77% vs 61%), suffer mental illness (10% vs 2%), and substance use disorders (54% vs 10%). People experiencing homelessness were not more likely to suffer surgical complications. However, male sex, older age, mental illness, and substance use were risk factors for poor surgical outcomes. Homelessness predicted greater odds of discharge against medical advice (4.3 times) and longer length of stay (1.25 times). These results highlighted the need for health interventions simultaneously addressing physical, mental health, and substance use issues in the care of PEH.

Mono- and three-tailed sugar and iminosugar decorated benzenesulfonamide carbonic anhydrase inhibitors.

A collection of novel mono- and three-tailed derivatives based on a sugar (glucose) or an iminosugar (trihydroxy piperidine) featuring a terminal benzenesulfonamide were synthesized to investigate the so-called "sugar" and "azasugar" approach with the aim of exploring the activity and selectivity towards the inhibition of human carbonic anhydrases (hCAs). The synthetic approach relies on a general copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction followed by an amine-isothiocyanate coupling. Biological assays were used to collect subtle information on the role of these single or multiple hydrophilic chains. Among the sugar-based inhibitors, the single-tailed compound 10 was identified as a better inhibitor than the reference compound (AAZ) towards three different hCAs, while, among the three sugar tailed derivatives, potent and selective inhibition was found for compounds 25 and 26. A promising and selective inhibitory activity was discovered for the iminosugar single-tailed compound 31 towards hCA VII (Ki = 9.7 nM).
