Accelerated Bone Healing via Electrical Stimulation

open access: yesAdvanced Science, EarlyView.
Electrical stimulation significantly impacts bone healing by enhancing osteoblast proliferation, differentiation, and vascularization through calmodulin/calcineurin/NFAT signaling. It also boosts macrophage function and cell migration, presenting a comprehensive approach to accelerating bone repair.

Secretory Phospholipase A2s in Insulin Resistance and Metabolism

open access: yesFrontiers in Endocrinology, 2021
The phospholipases A2 (PLA2) superfamily encompasses enzymes commonly found in mammalian tissues and snake venom. Many of these enzymes have unique tissue distribution, function, and substrate specificity suggesting distinct biological roles. In the past,

From sound to meaning in the auditory cortex: A neuronal representation and classification analysis [PDF]

open access: yesarXiv, 2023
The neural mechanisms underlying the comprehension of meaningful sounds are yet to be fully understood. While previous research has shown that the auditory cortex can classify auditory stimuli into distinct semantic categories, the specific contributions of the primary (A1) and the secondary auditory cortex (A2) to this process are not well understood.

Low-level laser therapy decreases local effects induced by myotoxins isolated from Bothrops jararacussu snake venom [PDF]

open access: yes, 2010
The prominent myotoxic effects induced by Bothrops jararacussu crude venom are due, in part, to its polycationic myotoxins, BthTX-I and BthTX-II. Both myotoxins have a phospholipase A2 structure: BthTX-II is an active enzyme Asp-49 PLA2, while BthTX-I is

Targeting Senescence with Apigenin Improves Chemotherapeutic Efficacy and Ameliorates Age‐Related Conditions in Mice

open access: yesAdvanced Science, EarlyView.
As a plant‐derived flavonoid, apigenin directly targets PRDX6 to inhibit its PLA2 activity, blocking HSPA8 activation and disturbing its interactions with ATM and p38MAPK in senescent cells. By dampening wide spectrum expression of the SASP, apigenin prevents loss of tissue homeostasis, improves organ function, and alleviates multiple age‐related ...

Apoptotic signaling through CD95 (Fas/Apo-1) activates an acidic sphingomyelinase. [PDF]

open access: yes, 1994
Intracellular pathways leading from membrane receptor engagement to apoptotic cell death are still poorly characterized. We investigated the intracellular signaling generated after cross-linking of CD95 (Fas/Apo-1 antigen), a broadly expressed cell ...

Engineering the Rod of Asclepius – A Biochemical Investigation of Snake Venom Components and their Application as Potential Cancer Treatments [PDF]

open access: yes, 2019
In the wild, venom is crucial to many snakes’ success as predators. While antivenin research focuses on combatting venoms’ abilities to disrupt physiological processes, new studies are attempting to manipulate these same abilities into anticancer ...

P/2010 A2 LINEAR II: dynamical dust modelling [PDF]

open access: yes, 2012
P/2010 A2 is an object on an asteroidal orbit that was observed to have an extended tail or debris trail in January 2010. In this work, we fit the outburst of P/2010 A2 with a conical burst model, and verify previous suspicions that this was a one--time collisional event rather than an sustained cometary outburst, implying that P/2010 A2 is not a new ...

Profiling Serine Hydrolases in the Leishmania Host‐Pathogen Interactome Using Cell‐Permeable Activity‐Based Fluorophosphonate Probes

open access: yesChemBioChem, Accepted Article.
Leishmaniasis, a vector borne neglected tropical disease, caused by the protozoan parasite Leishmania, is a major global public health challenge with millions of new cases annually. Treatment of leishmaniasis is difficult for many reasons including a multiple life‐cycle stages, involving both an infective insect vector form, the promastigote, and a ...
