Delamanid (DLM), a nitro-dihydroimidazooxazole derivative currently approved for pulmonary multidrug-resistant tuberculosis (TB) therapy, is a prodrug activated by mycobacterial 7,8-didemethyl-8-hydroxy 5-deazaflavin electron transfer coenzyme (F₄₂₀)-dependent nitroreductase (Ddn). Despite inhibiting the biosynthesis of a subclass of mycolic acids, the active DLM metabolite remained unknown. Comparative liquid chromatography-mass spectrometry (LC-MS) analysis of DLM metabolites revealed covalent binding of reduced DLM with a nicotinamide ring of NAD derivatives (oxidized form) in DLM-treated Mycobacterium tuberculosis var. Bacille de Calmette et Guérin. Isoniazid-resistant mutations in the type II NADH dehydrogenase gene (ndh) showed a higher intracellular NADH/NAD ratio and cross-resistance to DLM, which were restored by complementation of the mutants with wild-type ndh. Our data demonstrated for the first time the adduct formation of reduced DLM with NAD in mycobacterial cells and its importance in the action of DLM.

Understanding how coronary blood vessels form and regenerate during development and progression of cardiac diseases will shed light on the development of new treatment options targeting coronary artery diseases. Recent studies with the state-of-the-art technologies have identified novel origins of, as well as new, cellular and molecular mechanisms underlying the formation of coronary vessels in the postnatal heart, including collateral artery formation, endocardial-to-endothelial differentiation and mesenchymal-to-endothelial transition. These new mechanisms of coronary vessel formation and regeneration open up new possibilities targeting neovascularization for promoting cardiac repair and regeneration. Here, we highlight some recent studies on cellular mechanisms of coronary vessel formation, and discuss the potential impact and significance of the findings on basic research and clinical application for treating ischemic heart disease.

Maintenance of the proteome, ensuring the proper locations, proper conformations, appropriate concentrations, etc., is essential to preserve the health of an organism in the face of environmental insults, infectious diseases, and the challenges associated with aging. Maintaining the proteome is even more difficult in the background of inherited mutations that render a given protein and others handled by the same proteostasis machinery misfolding prone and/or aggregation prone. Maintenance of the proteome or maintaining proteostasis requires the orchestration of protein synthesis, folding, trafficking, and degradation by way of highly conserved, interacting, and competitive proteostasis pathways. Each subcellular compartment has a unique proteostasis network compromising common and specialized proteostasis maintenance pathways. Stress-responsive signaling pathways detect the misfolding and/or aggregation of proteins in specific subcellular compartments using stress sensors and respond by generating an active transcription factor. Subsequent transcriptional programs up-regulate proteostasis network capacity (i.e., ability to fold and degrade proteins in that compartment). Stress-responsive signaling pathways can also be linked by way of signaling cascades to nontranscriptional means to reestablish proteostasis (e.g., by translational attenuation). Proteostasis is also strongly influenced by the inherent kinetics and thermodynamics of the folding, misfolding, and aggregation of individual proteins, and these sequence-based attributes in combination with proteostasis network capacity together influence proteostasis. In this review, we will focus on the growing body of evidence that proteostasis deficits leading to human pathology can be reversed by pharmacologic adaptation of proteostasis network capacity through stress-responsive signaling pathway activation. The power of this approach will be exemplified by focusing on the ATF6 arm of the unfolded protein response stress responsive-signaling pathway that regulates proteostasis network capacity of the secretory pathway.

Background:

We assessed the ability to supplement existing epidemiologic/etiologic studies with data on treatment and clinical outcomes by linking to publicly available cancer registry and administrative databases.

BACKGROUND AND PURPOSE:

The massa intermedia is a normal midline transventricular thalamic connection. Massa intermedia aberrations are common in schizophrenia, Chiari II malformation, X-linked hydrocephalus, Cornelia de Lange syndrome, and diencephalic-mesencephalic junction dysplasia, among others. We have noticed that massa intermedia abnormalities often accompany other midline malformations. The massa intermedia has never been formally evaluated in a group of exclusively pediatric patients, to our knowledge. We sought to compare and contrast the prevalence, size, and location of the massa intermedia in pediatric patients with and without congenital midline brain abnormalities.

BACKGROUND AND PURPOSE:

Endovascular embolization only has been advocated for treatment of brain arteriovenous malformations in recent trials. Our aim was to evaluate the results of embolization only in a cohort of patients who were enrolled in the A Randomized Trial of Unruptured Brain Arteriovenous Malformations (ARUBA) study at 39 clinical sites in 9 countries.

BACKGROUND AND PURPOSE:

Embolization is widely performed to treat brain arteriovenous malformations, but little has been reported on factors contributing to complications. We retrospectively reviewed a nationwide surveillance to identify risk factors contributing to complications and short-term clinical outcomes in the endovascular treatment of brain arteriovenous malformations.

Microsoft earlier announced it will share new information on the Xbox Series X every month in 2020 calling it "Xbox 20/20." The first event will be held on May 7th at 8am PT / 11am ET and will focus on gameplay from third-party partners. 

The event in June has now been revealed it will focus on platform and services, according to Bloomberg.

It is possible the June event will see the unveiling of the long rumored weaker next generation Xbox, codenamed Lockhart, with an expected official name of Xbox Series S. The price and launch date for the Xbox Series X is also possible, as well as information on Game Pass, Xbox Live Gold and Project xCloud. 

The July event will be focused on upcoming first-party games from Xbox Game Studios. 

"These monthly moments will take place throughout the rest of the year and will be a way for us to engage, connect and celebrate with you about what’s in store for the next generation of gaming, including what’s next for Xbox Series X, Xbox Game Studios, Xbox Game Pass and Project xCloud," said Microsoft. "Every month will bring something different. Stay tuned to Xbox Wire for more details."

The Xbox Series X will launch in Holiday 2020.

Developer Mirari & Co. announced the science-fiction action platformer Dark Light for Windows PC via Steam Early Access on May 8 and later for the Nintendo Switch when the game leaves Steam Early Access. 

Mirari & Co. is looking to release the game within one year of the Steam Early Access release, however, it depends "on how we are taking players suggestions and advice to shaping the game."

View the latest trailer of the game below:

Here is an overview of the game:

Dark Light is a science-fiction action-platformer with unique gameplay. Explore an apocalyptic cyberpunk world full of supernatural beings. Encounter and defeat creatures of darkness invisible to the naked eye, detected only with the light source from your drone. Experience the horror and feel their presence as they surround you.

As a Dark Hunter you were dropped into a wreaked world. To survive, you need to equip yourself, fight your way through, and collect ‘shards’ from killing supernatural creatures to reinforce your energy. Through survival, you will explore the mysterious dark zones of the apocalypse world.

Key Features:

• Cinematic quality graphic, detailed characters and environment design, and vivid animation with lush visual effect.
• A variety of range, melee, and throwable weapons; unique items; and multiple ways to upgrade weapons, special equipment, and the player to shape your own character skills.
• Non-linear map structure for you to choose your own path to explore the dark zones. Encounter horrifying supernatural enemies, fearsome bosses, and friendly NPCs, and fight with invisible creatures that can only be seen in a special light source.
• Detect invisible enemies and reveal hidden paths with the special light source from your drone.
