Napping has been scientifically linked to various health benefits, including improved brain and heart health, cognition, creativity, and memory. Experts recommend napping between 1 to 4 p.m., when alertness naturally dips. The ideal nap duration is 20 to 40 minutes, although some researchers suggest a slightly longer hour-long nap. Preparing for a nap with meditation or muscle relaxation can enhance its restorative effects, and creating a consistent and comfortable environment is important. Drinking coffee before a nap can help invigorate you upon waking, and setting an alarm for 60 minutes or longer can enhance creativity by accessing the "space between wake and deep sleep."

While other variants require both the ACE2 and TMPRSS2 proteins to inject their genome into a cell, Omicron bound only to ACE2. Second, while the Delta variant often dove down to infect TMPRSS2-rich lung cells, Omicron replicated quickly in the airway above the lungs, which probably helped it spread from person to person. THE OMICRON CORONAVIRUS VARIANT WAS LIKELY THE FASTEST-SPREADING VIRUS IN HUMAN history. [Extracted from the article]

Development of an anatomically accurate 3-dimensional (3D) digital model of the human nasopharynx, oropharynx, and hypopharynx derived from published literature and radiographic imaging. Muscles of the pharynx, including the palatopharyngeus, superior, middle, and inferior constrictor, salpingopharyngeus and stylopharyngeus were manually segmented from a head and neck CT angiogram of a healthy 29-year-old female. Data derived from published anatomical studies were compiled to provide additional anatomical detail to each muscle. The eustachian tube and supporting structures, adjacent supporting structures, and adjacent major neurovasculature were also segmented. These anatomical details were then incorporated into the model by a 3D medical illustrator. A total of 6 muscles were segmented from CT angiography data as were the hyoid bone, thyroid and cricoid cartilage, epiglottis, skull base, course of the eustachian tube, and nearby major arteries and veins. Meshes were further refined in digital 3D space based on data from peer-reviewed anatomical studies. The left trigeminal, glossopharyngeal, and hypoglossal nerves were incorporated into the model to highlight important anatomical relationships relevant for surgery. Finally, the model was uploaded to a publicly available 3D repository, which can be accessed here (https://shorturl.at/qJO16). The pharynx is a complex 3D structure that plays a critical role in swallowing, speaking, and airway protection. By combining radiographic data with published anatomical descriptions, and through the collaboration between neuroradiology, head and neck surgery, and medical illustration, we developed an anatomically accurate, detailed 3D model of the pharynx for education and training purposes.

Development of an anatomically accurate, digital, 3-dimensional (3D) model of the masticator space, including the muscles of mastication and temporomandibular joint, by combining data from radiographic imaging and published literature, and augmenting this with medical illustration. The present study involved the manual segmentation of the muscles of mastication, namely the masseter, temporalis, medial pterygoid, and lateral pterygoid muscles, as well as the buccinator muscle from a head and neck CT angiogram of a healthy 29-year-old female. The skull base, supporting structures, and adjacent major arteries were also segmented from the same study. The segmentation was then refined based on a compilation of data from published anatomical studies, which were utilized to provide additional anatomical detail for each muscle. Published studies were also used to incorporate structures unable to be segmented by this imaging technique, specifically major cranial nerves and the temporomandibular joint. The resulting anatomical details were subsequently incorporated into a 3D model by a professional medical illustrator. A total of 5 left-sided muscles were segmented from CT angiography data and were incorporated with segmentations of the skull base and mandible. Meshes were further refined in digital 3D space based on data from peer-reviewed anatomical studies. The left temporomandibular joint, sphenomandibular ligament, and stylomandibular ligament, as well as the left trigeminal nerve and maxillary artery and its branches were incorporated into the model to highlight important surgical anatomical relationships. Finally, the model was uploaded to a publicly available 3D repository, available at https://shorturl.at/hnrVZ. This 3D study serves to demonstrate, in a layered fashion, the complex anatomy of the muscles of mastication, including their relationship with important cranial base and neurovascular structures relevant to common surgical procedures and approaches to the infratemporal fossa. Moreover, it serves as an adjunct to the other studies published in this issue. [ABSTRACT FROM AUTHOR]

Using published literature and radiographic imaging, this study aims to develop an anatomically accurate 3-dimensional (3D) digital model of the human parotid gland, submandibular gland, facial nerve, and adjacent anatomy. The model is available for viewing at https://shorturl.at/uzADZ. The left parotid and submandibular glands, parotid ducts, retromandibular vein, external carotid artery, and its relevant branches were segmented from a computed tomography (CT) angiography study of a healthy female. The object segmentations were exported and refined based on a literature review of relevant anatomical structures. These structures were incorporated into the head and neck model to ensure compatibility with other anatomical structures, such as the mandible and skull base. Following the segmentation of the parotid and submandibular glands, the parotid gland was divided into superficial and deep lobes based on the course of the retromandibular vein. The facial nerve and its branches were added according to the most common anatomical variants. The internal maxillary artery and its first-order branches were identified; when below the resolution of the patient's imaging study, these branches were added according to the most commonly described anatomical variants. This applies to all other neurovascular structures depicted in the final renders. This study demonstrates the critical anatomic landmarks related to surgery of the parotid and submandibular glands, with particular emphasis on vascular structures including the maxillary and facial arteries, the common facial vein, external jugular vein, and retromandibular vein, as well as the facial nerve (CN VII), great auricular nerve, auriculotemporal nerve, lingual nerve, and hypoglossal nerve. The associated 3D model can serve as a helpful tool for improving the understanding of anatomical relationships, particularly in the parotid space. [ABSTRACT FROM AUTHOR]

Thyroidectomies are performed routinely by the head and neck surgeon, especially for neoplastic disease.

Back when Fittipaldi, Walker and Wisell were racing the car, they'd have got on the power while still braking, getting the turbine spinning into its powerband ready for the exit. The chassis is an aluminium monocoque, with steel bulkheads for the engine and the suspension pick-up points, the bodywork predominantly glassfibre, with a huge one-piece mould for its upper surface, which lifts up and away from the car in one go. The fascinating Rover-BRM turbine car ran three times at Le Mans, and the pretty Howmet TX from America competed at Daytona, Le Mans and beyond later in the decade, but it was at Indianapolis that the technology really made its mark. But there was still Formula 1 With four-wheel-drive traction and a huge horsepower advantage over the Cosworth DFV-powered F1 cars of the time, Chapman could see the inherent potential in the 56, and at the start of 1970 the Fl-evolution 56B was born, embarking on a season of testing before its '71 race debut.
