Personal light treatment devices: a countermeasure to improve sleep, fatigue, and circadian misalignment in an operational setting.

Carefully timed light exposure is a promising countermeasure to overcome the negative sleep and circadian implications of shift work. However, many lighting interventions are static and applied at the group level (e.g.

The lack of thematic continuity in dreams with scene and plot discontinuities.

A central tenet of Freudian dream theory holds that there is thematic coherence within all dreams, even those containing scene and plot discontinuities. While other models support varying degrees of dream coherence, none address the question of how, or even whether, coherence can be identified in dreams with such discontinuities. Here, we objectively test the ability of judges to evaluate the coherence of individual dream narratives.

Does fragmented sleep mediate the relationship between deficits in sleep spindles and memory consolidation in schizophrenia?

Study Objectives: Sleep spindles, defining electroencephalographic oscillations of nonrapid eye movement (NREM) stage 2 sleep (N2), mediate sleep-dependent memory consolidation (SDMC). Spindles are also thought to protect sleep continuity by suppressing thalamocortical sensory relay. Schizophrenia is characterized by spindle deficits and a correlated reduction of SDMC.

Measuring the Impact of Beamwidth on the Correlation Distance of 60 GHz Indoor and Outdoor Channels.

Due to narrow beamwidth and channel sparseness, millimeter-wave receivers will detect much less multipath than their microwave counterparts, fundamentally changing the small-scale fading properties. By corollary, the de facto Rayleigh-Rice model, which assumes a rich multipath environment interpreted by the Clarke-Jakes omnidirectional ring of scatterers, does not provide an accurate description of this fading nor of the correlation distance that it predicts. Rather, a model interpreted by a directional ring of scatterers, recently proposed in seminal work by Va et al.

Mechanically robust surface-degradable implant from fiber silk composites demonstrates regenerative potential.

Through millions of years of evolution, bones have developed a complex and elegant hierarchical structure, utilizing tropocollagen and hydroxyapatite to attain an intricate balance between modulus, strength, and toughness. In this study, continuous fiber silk composites (CFSCs) of large size are prepared to mimic the hierarchical structure of natural bones, through the inheritance of the hierarchical structure of fiber silk and the integration with a polyester matrix. Due to the robust interface between the matrix and fiber silk, CFSCs show maintained stable long-term mechanical performance under wet conditions.

DNA methylation of long noncoding RNA cytochrome B in diabetic retinopathy.

Diabetic retinopathy, a microvascular complication of diabetes, is the leading cause of blindness in adults, but the molecular mechanism of its development remains unclear. Retinal mitochondrial DNA is damaged and hypermethylated, and mtDNA-encoded genes are downregulated. Expression of a long noncoding RNA (larger than 200 nucleotides, which does not translate into proteins), encoded by mtDNA, cytochrome B (Lnc), is also downregulated.

Terahertz-Rate Kerr-Microresonator Optical Clockwork.

Kerr microresonators generate interesting and useful fundamental states of electromagnetic radiation through nonlinear interactions of continuous-wave (CW) laser light. With photonic-integration techniques, functional devices with low noise, small size, low-power consumption, scalable fabrication, and heterogeneous combinations of photonics and electronics can be realized. Kerr solitons, which stably circulate in a Kerr microresonator, have emerged as a source of coherent, ultrafast pulse trains and ultra-broadband optical-frequency combs.

Changes in Plasma Levels of Prestin and Otolin-1 in Dental Students.

Introduction: Dentists and dental professionals report a high prevalence of noise-induced hearing loss (NIHL) and related symptoms. Chronic exposure to high-frequency dental instrument sounds, which can damage the outer hair cells (OHCs) of the cochlea, is strongly linked to their NIHL. Similarly, dental students in teaching clinics often report symptoms associated with NIHL.

A Comparative Review of the Terms Epipharyngitis and Nasopharyngitis in Medical Literature.

This review explores the usage of the term "epipharyngitis" in medical literature, particularly in non-English-speaking contexts. The term, although rarely used in contemporary English-language medical literature, may lead to confusion due to its overlap with more commonly used terms like "nasopharyngitis." This review aims to trace the origins of the term, analyze its usage across different languages, and discuss the implications of term differences in clinical practice and medical education.

Complex Cardiovascular Management in an 80-Year-Old Female With Gastrointestinal Bleeds and Klatskin Tumor: A Case of ST-Elevation Myocardial Infarction (MI) Management Complicated by Severe Anemia and Post-MI Ventricular Septal Defect Development.

Managing acute coronary syndrome (ACS) in patients with a recent history of gastrointestinal bleeding presents a unique and challenging clinical dilemma, necessitating a careful balance between minimizing ischemic risk and avoiding potentially life-threatening rebleeding. Standard treatment for ACS typically involves dual antiplatelet therapy (DAPT) to prevent recurrent thrombotic events. However, in patients with recent gastrointestinal hemorrhage or significant anemia, these therapies may substantially increase the risk of life-threatening bleeding, complicating the decision-making process and often leading to conservative management strategies.

Diffuse Large B-Cell Lymphoma Presenting Primarily as a Cutaneous Leg Lesion: A Case Report and Literature Review.

Primary cutaneous B-cell lymphoma (PCBCL) has three subtypes, among those, the leg type variant is the rarest with the highest rates of relapse and recurrence making it an intriguing focus for researchers. Nevertheless, prior to framing a diagnosis solely based on the lesion's location, it is prudent to reconsider whether it is genuinely a primary cutaneous B-cell lymphoma (PCBCL) or if it aligns more closely with the more prevalent lymphoma variants such as diffuse large B-cell lymphoma (DLBCL) with cutaneous involvement. We are reporting a case of an 85-year-old African American lady, who presented with unilateral left leg DLBCL with cutaneous involvement.

Pacemaker-Induced Superior Vena Cava Syndrome.

Superior vena cava (SVC) syndrome is a result of impaired blood flow from the SVC to the right atrium, leading to venous congestion in the head and neck. It can be caused by clotting disorders or compressive tumors of the head and neck but has become more prevalent in the setting of implantable devices such as pacemakers. As such, managing these patients can present challenges for physicians who have to account for SVC syndrome as well as their underlying condition requiring an implantable cardiac device.

Diffuse Pulmonary Ossification (DPO) in the Setting of Firefighter Occupation.
