IJERPH, Vol. 20, Pages 6810: School Memories about Homophobic Bullying: A Study Based on Cultural-Historical Psychology
This study is based on cultural-historical psychology in intersection with gender and sexuality studies. In-depth online interviews were conducted with three young subjects who identified themselves as non-heterosexual. The interviews were recorded, transcribed, and analyzed through the analytical discourse tool defined as Nuclei of Meanings. The results were organized in two topics of discussion: (a) the problems associated with non-heterosexual identity in schools; (b) the search for other ways of experiencing sexual identity in school. Throughout the article, reflections were held about the challenges participants had t...

Viruses, Vol. 15, Pages 1981: A Baculovirus Expression Vector Derived Entirely from Non-Templated, Chemically Synthesized DNA Parts
Slack Baculovirus expression system1s are a widely used tool in recombinant protein and biologics production. To enable the possibility of genome modifications unconstrained through low-throughput and bespoke classical genome manipulation techniques, we set out to construct a baculovirus vector (>130 kb dsDNA) built from modular, chemically synthesized DNA parts. We constructed a synthetic version of Autographa californica multiple nucleopolyhedrovirus (AcMNPV) through two steps of hierarchical Golden Gate assembly. Over 140 restriction endonuclease sites were removed to enable the discrimination of the synt...

Sensors, Vol. 23, Pages 8040: Joint Power and Channel Allocation for Non-Orthogonal Multiple Access in 5G Networks and Beyond
nkler Spectral efficiency is a crucial metric in wireless communication systems, as it defines how much information can be transmitted over a given amount of spectrum resources. Non-orthogonal multiple access (NOMA) is a promising technology that has captured the interest of the wireless research community because of its capacity to enhance spectral efficiency. NOMA allows multiple users to share the same frequency band and time slot by assigning different power levels and modulation schemes to different users. Furthermore, channel assignment is a critical challenge in OFDMA-NOMA systems that must be addressed to achie...

Sensors, Vol. 23, Pages 8038: An Access Control Scheme Based on Blockchain and Ciphertext Policy-Attribute Based Encryption
i Sihui Liu Ciphertext policy–attribute-based encryption (CP-ABE), which provides fine-grained access control and ensures data confidentiality, is widely used in data sharing. However, traditional CP-ABE schemes often choose to outsource data to untrusted third-party cloud service providers for storage or to verify users’ access rights through third parties, which increases the risk of privacy leakage and also suffers from the problem of opaque permission verification. This paper proposes an access control scheme based on blockchain and CP-ABE, which is based on multiple authorization cent...

Characterization of the extracellular vesicles, ultrastructural morphology, and intercellular interactions of multiple clinical isolates of the brain-eating amoeba, Naegleria fowleri
DiscussionHerein we propose that N. fowleri secretes EVs in clusters from the plasma membrane, from multivesicular bodies, and via beading of thin filaments extruding from the membrane. Uptake assays demonstrate that EVs are taken up by other amoebae and mammalian cells, and we observed a real-time increase in metabolic activity for mammalian cells exposed to EVs from amoebae. Proteomic analysis revealed >2,000 proteins within the N. fowleri-secreted EVs, providing targets for the development of diagnostics or therapeutics. Our work expands the knowledge of intercellular interactions among these amoebae and subsequently...

Months after hospitalization for COVID-19, MRIs reveal multiorgan damage
This study found abnormal MRI results in 20% to 25% of both controls and hospitalized patients, suggesting “a lot of these cardiac abnormalities that were seen in the COVID group must have been there beforehand.” Post–COVID-19 patients with lingering cardiac symptoms might have disorders like heartbeat irregularities that aren’t always visible with MRI, or dysfunction in other organs, he adds. Although it can offer clues to an organ’s health, MRI is an imperfect measure of how a patient is faring after infection. Researchers found no connection between abnormal liver MRIs and symptoms such as gastroin...

Mars Sample Return got a new price tag. It ’s big
NASA’s audacious Mars Sample Return (MSR) mission has serious technical flaws and “unrealistic” assumptions about its budget and timetable, an independent review found in a report released yesterday . Originally estimated to cost some $4 billion, the reviewers found that NASA’s share of the mission could end up costing between $8 billion to $11 billion, and that launch could happen no sooner than 2030, 2 years later than now planned. A joint project between NASA and the European Space Agency (ESA), MSR would gather rocks collected by the Perseverance rover, which has been drilling samples...

What It Will Take to Avoid a Tripledemic This Winter
Over the coming months, more than 100,000 Americans will likely die, mostly unnecessarily, from respiratory infections. Yes, that is the reality we are now facing this fall and winter—and likely every fall and winter for the foreseeable future. Unless we act. Between flu, COVID-19, and RSV, we are likely looking at a very large number of Americans getting sick, ending up in the hospital, and dying. Most of these Americans will be our most vulnerable: older Americans, the youngest children, and those with chronic diseases. And that number of 100,000 may be an underestimate, given that many of these infections go undet...
