Although most previous studies in this area used
recombinant adiponectin, herein, the author used native high-molecular-weight
(HMW) adiponectin purified from human plasma, which is considered the most
active form of circulating adiponectin. The current results clearly demonstrate
that native HMW adiponectin preferentially inhibits lipopolysaccharide-induced interleukin-1β expression but not tumor
necrosis factor-α
expression by inhibiting the Akt-C/EBPβ inflammatory signaling pathway in macrophages. Furthermore, HMW
adiponectin preconditioning is essential for achieving the anti-inflammatory
effects of adiponectin. Thus, these findings highlight
the regulatory mechanisms underlying the anti-inflammatory function of adiponectin.
Authors suggest that plant extracts, including
quercetin and oenothein B, reduce the amount of virus in the cell supernatants
and induce cytotoxicity in HIV-1-infected T cells but not HTLV-1-infected T
cells. The large amount of oenothein B were detected in Onagraceae. Thus, the plant
extracts might block the HIV-1 release and kill the HIV-1-infected cells.
Consequently, the plant extracts from the plant library of Turkey might be
suitable candidates to develop novel anti-retroviral drugs that target the late
phase of the HIV-1 life cycle.
Citrus
sudachi is a popular fruit in Tokushima
Prefecture, Japan, and its peel contains high amounts of polymethoxyflavones
with the most abundant being sudachitin (SDC) followed by demethoxysudachitin (DMSDC).
The effects of SDC and DMSDC on the cardiovascular system have not been
investigated. The present study aimed to investigate the effects of SDC and
DMSDC on vascular tonus and to investigate mechanism of action of SDC using aorta
preparations isolated from rats. The results demonstrated that SDC and DMSDC
cause endothelial-independent relaxation, and that the mechanism of
vasorelaxation by SDC is associated with the enhancement of cAMP- and
cGMP-dependent pathways.
Antidepressants, such as
milnacipran, a serotonin and noradrenaline reuptake inhibitor, and mirtazapine,
a noradrenergic and specific serotonergic antidepressant attenuate the
induction of scratching events by chloroquine (CQ) or histamine. However, it
remains unclear whether serotonin or noradrenaline is involved in attenuating
effects of these antidepressants. Miyahara and colleagues show that 5-HT4
and 5-HT6 receptors are involved in the amelioration of CQ-induced
scratches, but not histamine-induced scratches, engendered by the antidepressants.
These findings suggest that 5-HT4, 5-HT5, and 5-HT6
receptors play differential roles in acute pruriceptive processing after
administration of CQ or histamine.
The authors validated the
modified Cockcroft-Gault equation, developed previously for aged-oriented
cohort, in a newly obtained dataset and found that good renal function estimates
were obtained for patients exceeding 65 years of age. Using statistical
analysis, estimates for a subset of patients in this cohort were identified to
be inadequate and this deviation from estimates was attributed to a decreased
albumin level. A multivariate linear regression estimating equation was
developed for this region by incorporating body composition parameters. A flow
diagram was proposed to select an appropriate renal function estimating
equation particularly for older patients.
