Στην βιολογία, το περιβάλλον μπορεί να καθοριστεί σαν ενα σύνολο κλιματικών, βιοτικών, κοινωνικών και εδαφικών παραγόντων που δρουν σε έναν οργανισμό και καθορίζουν την ανάπτυξη και την επιβίωση του. Έτσι, περιλαμβάνει οτιδήποτε μπορεί να επηρεάσει άμεσα τον μεταβολισμό ή τη συμπεριφορά των ζωντανών οργανισμών ή ειδών, όπως το φως, ο αέρας, το νερό, το έδαφος και άλλοι παράγοντες.

Στην αρχιτεκτονική, την εργονομία και την ασφάλεια στην εργασία, περιβάλλον είναι το σύνολο των χαρακτηριστικών ενός δωματίου ή κτιρίου που επηρεάζουν την ποιότητα ζωής και την αποδοτικότητα, περιλαμβανομένων των διαστάσεων και της διαρρύθμισης των χώρων διαβίωσης και της επίπλωσης, του φωτισμού, του αερισμού, της θερμοκρασίας, του θορύβου κλπ. Επίσης μπορεί να αναφέρεται στο σύνολο των δομικών κατασκευών. Δείτε επίσης το άρθρο για το δομημένο περιβάλλον.
Στην ψυχολογία, περιβαλλοντισμός είναι η θεωρία ότι το περιβάλλον (με τη γενική και κοινωνική έννοια) παίζει μεγαλύτερο ρόλο από την κληρονομικότητα καθορίζοντας την ανάπτυξη ενός ατόμου. Συγκεκριμένα, το περιβάλλον είναι ένας σημαντικός παράγοντας πολλών ψυχολογικών θεωριών.
Στην τέχνη, το περιβάλλον αποτελεί κινητήριο μοχλό και μούσα εμπνέοντας τους ζωγράφους ή τους ποιητές. Σε όλες τις μορφές της Τέχνης αποτελεί έμπνευση και οι Καλές Τέχνες φανερώνουν την επιρροή οπού άσκησε σε όλους τους καλλιτέχνες με όποιο είδος Τέχνης κι αν ασχολούνται. Ο άνθρωπος μέσα στο περιβάλλον δημιουργεί Μουσική, Ζωγραφική, Ποίηση, Γλυπτική, χορό, τραγούδι, θέατρο, αλλά και όλες οι μορφές τέχνης έχουν άμεση έμπνευση από το περιβάλλον.

Novel Methylated DNA Markers in the Surveillance of Colorectal Cancer Recurrence
Novel Methylated DNA Markers in the Surveillance of Colorectal Cancer Recurrence: Purpose: We aimed to assess the concordance of colorectal cancer (CRC)-associated methylated DNA markers (MDMs) in primary and metastatic CRC for feasibility in detection of distantly recurrent/metastatic CRC in plasma. Experimental Design: A panel of previously discovered CRC-associated MDMs was selected. MDMs from primary and paired metastatic CRC tissue were assayed with quantitative methylation-specific PCR. Plasma...

Image-guided surgical system
General first-order target registration error model considering a coordinate reference frame in an image-guided surgical system: AbstractPoint-based rigid registration (PBRR) techniques are widely used in many aspects of image-guided surgery (IGS). Accurately estimating target registration error (TRE) statistics is of essential value for medical applications such as optically surgical tool-tip tracking and image registration. For example, knowing the TRE distribution statistics of surgical tool tip...

The Virtual Circular Genome Model for Primordial RNA Replication
The Virtual Circular Genome Model for Primordial RNA Replication [Hypothesis]: We propose a model for the replication of primordial protocell genomes that builds upon recent advances in the nonenzymatic copying of RNA. We suggest that the original genomes consisted of collections of oligonucleotides beginning and ending at all possible positions on both strands of one or more virtual circular sequences. Replication is driven by feeding with activated monomers and by the activation of monomers and...

SMARCA4/SMARCA2-deficient Carcinoma of the Esophagus and Gastroesophageal Junction
SMARCA4/SMARCA2-deficient Carcinoma of the Esophagus and Gastroesophageal Junction: Undifferentiated carcinoma of the esophagus and gastroesophageal junction is a recently recognized entity in the fifth edition of the World Health Organization Classification of Digestive Tumors and is diagnostically challenging, particularly on small biopsies. SMARCA4 and SMARCA2 are chromatin remodeling genes with key roles in oncogenesis. We retrieved 14 cases of SMARCA4/SMARCA2-deficient undifferentiated carcinoma...

Molecular Profiling of Clear Cell Myoepithelial Carcinoma of Salivary Glands With EWSR1 Rearrangement Identifies Frequent PLAG1 Gene Fusions But No EWSR1 Fusion Transcripts
Molecular Profiling of Clear Cell Myoepithelial Carcinoma of Salivary Glands With EWSR1 Rearrangement Identifies Frequent PLAG1 Gene Fusions But No EWSR1 Fusion Transcripts: Myoepithelial carcinoma of salivary glands is an underrecognized and challenging entity with a broad morphologic spectrum, including an EWSR1-rearranged clear cell variant. Myoepithelial carcinoma is generally aggressive with largely unknown genetic features. A retrospective review of Salivary Gland Tumor Registry in Pilsen searching...

Evaluation of sleep quality and restless legs syndrome in adult patients with sickle cell anemia
Evaluation of sleep quality and restless legs syndrome in adult patients with sickle cell anemia: AbstractPurposeTo determine the prevalence of poor sleep quality and RLS in adult patients with sickle cell anemia (SCA). The second aim was to identify the risk factors for RLS and impairment of sleep quality in SCA patients. Materials and methodsPatients at least 18 years old, with hemoglobin electrophoresis confirmation of sickle cell disease, were included. Restless legs syndrome...

Atypical spinal neurocytoma with EGFR mutation in a 12-year-old boy
A rare case of atypical spinal neurocytoma with EGFR mutation in a 12-year-old boy: AbstractSpinal neurocytoma (SN), although frequently reportedly as tumors of the central nervous system (CNS), are a distinct class of tumors, which can achieve a better prognosis following subtotal or gross total tumor resection. Nonetheless, even with the premise of successful treatment after tumor resection, poor prognosis after treatment due to the SN high proliferation index (typically known as atypical SN) have...
