Osteoblast‐CD4+ CTL Crosstalk Mediated by SIRT1/DAAM2 Axis Prevents Age‐Related Bone Loss

Advanced Science, EarlyView.
In the osteoblastic niche, SIRT1 activates and recruits CD4+ CTLs by increasing DAAM2 expression via EZH2 deacetylation and boosting the secretion of key chemokines, such as CCL3, CCL5, and CXCL10. Then, CD4+ CTL directly eliminates senescent osteoblasts in an MHC‐II‐dependent way, thereby slowing down the process of bone ageing and effectively ...

Adipose Tissue Macrophages as Initiators of Exacerbated Periodontitis in Estrogen‐Deficient Environments via the Amplifier Extracellular Vesicles

Advanced Science, EarlyView.
Chronic systemic inflammation, worsened by estrogen deficiency, underlies and exacerbates periodontitis. Proinflammatory macrophages within visceral adipose tissue are hyperactivated due to hyper‐DNA methylation, releasing small extracellular vesicles (sEVs) similar to those of their parent cells.

Weak if any effect of estrogen on spatial memory in rats [PDF]

, 2002
In a number of species, males appear to have spatial abilities that are superior to those of females. The favored explanation for this cognitive difference is hormonal: higher testosterone levels in males than in females.

Assessing estrogenic activity of Nigella sativa in ovariectomized rats using vaginal cornification assay. [PDF]

, 2011
The aim of this study was to determine the estrogenic activity of Nigella sativa (NS) by vaginal cornification assay using an ovariectomized rat model. Forty ovariectomized Sprague Dawley rats, weighting 250 to 350 g were used in the study. N. sativa

Pharmacological effect of one icv dose of Allopregnanolone in female rat: behavioural profile [PDF]

, 2015
We have previously observed that intracerebroventricular allopregnanolone (ALLO) injection produced an anxiolytic effect and inhibited sexual receptivity when the test was performed in a separate manner. Also, ALLO reverts learning deficit in female rats

Single-Dose Local Simvastatin Injection Improves Implant Fixation via Increased Angiogenesis and Bone Formation in an Ovariectomized Rat Model

Medical Science Monitor, 2015
Background Statins have been reported to promote bone formation. However, taken orally, their bioavailability is low to the bones. Implant therapies require a local repair response, topical application of osteoinductive agents, or biomaterials that ...

Bioactive siRNA‐Based Liposomes Promoted Tendon‐Bone Healing in Osteoporotic Mice by Recovering the Stemness of CD248+ TSPCs

Advanced Science, EarlyView.
In this study, it is found that osteoporosis leads to disturbances in the Extracellular Matrix (ECM)of tendons and thus causes a decrease in TSPC stemness, resulting in a rotator cuff that is easily damaged and prone to retearing after repair. Targeted intervention with si‐CD248‐loaded liposomes can restore TSPC stemness, promote tendon‐bone healing ...

Synthetic epoxy-pregnan steroids: effects on anxiety behavior in rats [PDF]

, 2016
Neurosteroids like 3α-OH-5α-pregnan-20-one (allopregnanolone) and 3α-OH-5β-pregnan-20-one (pregnanolone) modulate the γ-aminobutyric acid-A (GABAA) receptor function and produce several effects that can be considered for therapeutical pruposes like ...
